Conference Coverage

Modifying 12 risk factors over the life course could delay or prevent 40% of dementia cases, according to an update of the Lancet Commission on Dementia Prevention, Intervention, and Care.

The original report, published in 2017, identified nine modifiable risk factors that were estimated to be responsible for one-third of dementia cases. The commission has now added three new modifiable risk factors to the list.

“We reconvened the 2017 Lancet Commission on Dementia Prevention, Intervention, and Care to identify the evidence for advances likely to have the greatest impact since our 2017 paper,” the authors wrote.

The 2020 report was presented at the virtual annual meeting of the Alzheimer’s Association International Conference (AAIC) 2020 and also was  published online July 30 in the Lancet.
 

Alcohol, TBI, air pollution

The three new risk factors that have been added in the latest update are excessive alcohol intake, traumatic brain injury (TBI), and air pollution. The original nine risk factors were not completing secondary education; hypertension; obesity; hearing loss; smoking; depression; physical inactivity; social isolation; and diabetes. Together, these 12 risk factors are estimated to account for 40% of the world’s dementia cases.

“We knew in 2017 when we published our first report with the nine risk factors that they would only be part of the story and that several other factors would likely be involved,” said lead author Gill Livingston, MD, professor, University College London (England). “We now have more published data giving enough evidence” to justify adding the three new factors to the list, she said.

The report includes the following nine recommendations for policymakers and individuals to prevent risk for dementia in the general population:

• Aim to maintain systolic blood pressure of 130 mm Hg or less in midlife from around age 40 years.
• Encourage use of hearing aids for hearing loss, and reduce hearing loss by protecting ears from high noise levels.
• Reduce exposure to air pollution and second-hand tobacco smoke.
• Prevent , particularly by targeting high-risk occupations and transport.
• Prevent alcohol misuse and limit drinking to less than 21 units per week.
• Stop smoking and support individuals to stop smoking, which the authors stress is beneficial at any age.
• Provide all children with primary and secondary education.
• Lead an active life into midlife and possibly later life.
• Reduce obesity and diabetes.

The report also summarizes the evidence supporting the three new risk factors for dementia.

TBI is usually caused by car, motorcycle, and bicycle injuries; military exposures; boxing, horse riding, and other recreational sports; firearms; and falls. The report notes that a single severe TBI is associated in humans and in mouse models with widespread hyperphosphorylated tau pathology. It also cites several nationwide studies that show that TBI is linked with a significantly increased risk for long-term dementia.

“We are not advising against partaking in sports, as playing sports is healthy. But we are urging people to take precautions to protect themselves properly,” Dr. Livingston said.

For excessive alcohol consumption, the report states that an “increasing body of evidence is emerging on alcohol’s complex relationship with cognition and dementia outcomes from a variety of sources including detailed cohorts and large-scale record-based studies.” One French study, which included more than 31 million individuals admitted to the hospital, showed that alcohol use disorders were associated with a threefold increased dementia risk. However, other studies have suggested that moderate drinking may be protective.

“We are not saying it is bad to drink, but we are saying it is bad to drink more than 21 units a week,” Dr. Livingston noted.

On air pollution, the report notes that in animal studies, airborne particulate pollutants have been found to accelerate neurodegenerative processes. Also, high nitrogen dioxide concentrations, fine ambient particulate matter from traffic exhaust, and residential wood burning have been shown in past research to be associated with increased dementia incidence.

“While we need international policy on reducing air pollution, individuals can take some action to reduce their risk,” Dr. Livingston said. For example, she suggested avoiding walking right next to busy roads and instead walking “a few streets back if possible.”
 

Hearing loss

The researchers assessed how much each risk factor contributes to dementia, expressed as the population-attributable fraction (PAF). Hearing loss had the greatest effect, accounting for an estimated 8.2% of dementia cases. This was followed by lower education levels in young people (7.1%) and smoking (5.2%).

Dr. Livingston noted that the evidence that hearing loss is one of the most important risk factors for dementia is very strong. New studies show that correcting hearing loss with hearing aids negates any increased risk.

Hearing loss “has both a high relative risk for dementia and is a common problem, so it contributes a significant amount to dementia cases. This is really something that we can reduce relatively easily by encouraging use of hearing aids. They need to be made more accessible, more comfortable, and more acceptable,” she said.

“This could make a huge difference in reducing dementia cases in the future,” Dr. Livingston added.

Other risk factors for which the evidence base has strengthened since the 2017 report include systolic blood pressure, social interaction, and early-life education.

Dr. Livingston noted that the SPRINT MIND trial showed that aiming for a target systolic blood pressure of 120 mm Hg reduced risk for future mild cognitive impairment. “Before, we thought under 140 was the target, but now are recommending under 130 to reduce risks of dementia,” she said.

Evidence on social interaction “has been very consistent, and we now have more certainty on this. It is now well established that increased social interaction in midlife reduces dementia in late life,” said Dr. Livingston.

On the benefits of education in the young, she noted that it has been known for some time that education for individuals younger than 11 years is important in reducing later-life dementia. However, it is now thought that education to the age of 20 also makes a difference.

“While keeping the brain active in later years has some positive effects, increasing brain activity in young people seems to be more important. This is probably because of the better plasticity of the brain in the young,” she said.
 

Sleep and diet

Two risk factors that have not made it onto the list are diet and sleep. “While there has also been a lot more data published on nutrition and sleep with regard to dementia in the last few years, we didn’t think the evidence stacked up enough to include these on the list of modifiable risk factors,” Dr. Livingston said.

The report cites studies that suggest that both more sleep and less sleep are associated with increased risk for dementia, which the authors thought did not make “biological sense.” In addition, other underlying factors involved in sleep, such as depression, apathy, and different sleep patterns, may be symptoms of early dementia.

More data have been published on diet and dementia, “but there isn’t any individual vitamin deficit that is associated with the condition. The evidence is quite clear on that,” Dr. Livingston said. “Global diets, such as the Mediterranean or Nordic diets, can probably make a difference, but there doesn’t seem to be any one particular element that is needed,” she noted.

“We just recommend to eat a healthy diet and stay a healthy weight. Diet is very connected to economic circumstances and so very difficult to separate out as a risk factor. We do think it is linked, but we are not convinced enough to put it in the model,” she added.

Among other key information that has become available since 2017, Dr. Livingston highlighted new data showing that dementia is more common in less privileged populations, including Black and minority ethnic groups and low- and middle-income countries.

Although dementia was traditionally considered a disease of high-income countries, that has now been shown not to be the case. “People in low- and middle-income countries are now living longer and so are developing dementia more, and they have higher rates of many of the risk factors, including smoking and low education levels. There is a huge potential for prevention in these countries,” said Dr. Livingston.

She also highlighted new evidence showing that patients with dementia do not do well when admitted to the hospital. “So we need to do more to keep them well at home,” she said.
 

COVID-19 advice

The report also has a section on COVID-19. It points out that patients with dementia are particularly vulnerable to the disease because of their age, multimorbidities, and difficulties in maintaining physical distancing. Death certificates from the United Kingdom indicate that dementia and Alzheimer’s disease were the most common underlying conditions (present in 25.6% of all deaths involving COVID-19).

The situation is particularly concerning in care homes. In one U.S. study, nursing home residents living with dementia made up 52% of COVID-19 cases, yet they accounted for 72% of all deaths (increased risk, 1.7), the commission reported.

The authors recommended rigorous public health measures, such as protective equipment and hygiene, not moving staff or residents between care homes, and not admitting new residents when their COVID-19 status is unknown. The report also recommends regular testing of staff in care homes and the provision of oxygen therapy at the home to avoid hospital admission.

It is also important to reduce isolation by providing the necessary equipment to relatives and offering them brief training on how to protect themselves and others from COVID-19 so that they can visit their relatives with dementia in nursing homes safely when it is allowed.
 

“Most comprehensive overview to date”

Alzheimer’s Research UK welcomed the new report. “This is the most comprehensive overview into dementia risk to date, building on previous work by this commission and moving our understanding forward,” Rosa Sancho, PhD, head of research at the charity, said.

“This report underlines the importance of acting at a personal and policy level to reduce dementia risk. With Alzheimer’s Research UK’s Dementia Attitudes Monitor showing just a third of people think it’s possible to reduce their risk of developing dementia, there’s clearly much to do here to increase people’s awareness of the steps they can take,” Dr. Sancho said.

She added that, although there is “no surefire way of preventing dementia,” the best way to keep a brain healthy as it ages is for an individual to stay physically and mentally active, eat a healthy balanced diet, not smoke, drink only within the recommended limits, and keep weight, cholesterol level, and blood pressure in check. “With no treatments yet able to slow or stop the onset of dementia, taking action to reduce these risks is an important part of our strategy for tackling the condition,” Dr. Sancho said.

The Lancet Commission is partnered by University College London, the Alzheimer’s Society UK, the Economic and Social Research Council, and Alzheimer’s Research UK, which funded fares, accommodation, and food for the commission meeting but had no role in the writing of the manuscript or the decision to submit it for publication.

The rapid decline in pediatric hospital visits that came quickly after COVID-19 has emerged as a major public health threat, creating the need for adaptations among those offering hospital-based care, according to an objective look at patient numbers that was presented at the virtual Pediatric Hospital Medicine.

“Pre-COVID, operating margins had already taken a significant decline – and there are lots of different reasons for why this was happening – but a lot of hospitals in the United States were going from seeing about a 5% operating margin to closer to 2% to 3%,” said Magna Dias, MD, medical director, pediatric inpatient services, at Yale New Haven Children’s Hospital, Bridgeport, Conn.

This nearly 50% decline “was already putting pressure on us in the community hospital setting where pediatrics is not necessarily generating a ton of revenue to justify our programs, but post COVID, our operating revenue – and this is a report from May – was down 282%,” Dr. Dias reported.

Dr. Dias said that hundreds of hospitals have furloughed workers in the United States since the pandemic began. Although the job losses are not confined to pediatric care, statistics show that pediatrics is one of the hardest hit specialties.

“Looking specifically at ED [emergency department] visits under age 14, one study showed a 71% to 72% decrease post COVID,” Dr. Dias said. This included a 97% reduction in ED visits for flu and more than an 80% reduction in visits for asthma, otitis media, and nausea or vomiting.

It is not clear when children will return to the hospital in pre-COVID-19 numbers, but it might not be soon if the a second wave of infections follows the first, according to Dr. Dias. She suggested that pediatric hospitalists should be thinking about how to expand their services.

“One thing we are really good at in terms of working in the community hospital is diversification. We are used to working in more than one area and being flexible,” Dr. Dias said. Quoting Charles Darwin, who concluded that adaption to change predicts species survival, Dr. Dias advised pediatric hospitalists to look for new opportunities.

Taking on a broader range of responsibilities will not be a significant leap for many pediatric hospitalists. In a survey conducted several years ago by the American Academy of Pediatrics (AAP), hospital staff pediatricians were associated with activities ranging from work in the neonatal intensive care unit to primary ED coverage, according to Dr. Dias. Now with declining patient volumes on pediatric floors, she foresees an even greater expansion, including the care of young adults.

One organization formed in response to the COVID-19 pandemic, called the Pediatric Overflow Planning Contingency Response Network (POPCoRN) has been taking a lead in guiding the delivery of adult care in a pediatric environment. As a cochair of a community hospital special interest group within POPCoRN, Dr. Dias said she has participated in these discussions.

“At some centers, they have gone from age 18 to 21, some have gone up to age 25, some have gone up to 30 years,” she said.

Many centers are working to leverage telemedicine to reach pediatric patients no longer coming to the hospital, according to Dr. Dias.

“There are a lot of people being very creative in telemedicine,” she said. While it is considered as one way “to keep children at your institution,” Dr. Dias said others are considering how telemedicine might provide new opportunities. For one example, telemedicine might be an opportunity to deliver care in rural hospitals without pediatric services.

In an AAP survey of pediatric hospitalists conducted several years ago, justifying services was listed as the second most important concern right after access to subspecialty support. Due to COVID-19, Dr. Dias expects the order of these concerns to flip. Indeed, she predicted that many pediatric hospitalists are going to need to reassess their programs.

“We have started looking at what are our opportunities for building back revenue as well as how to recession-proof our practices should there be another surge and another decrease in pediatric volume,” Dr. Dias said.

The changes in pediatric care are not confined to the hospital setting. According to Amy H. Porter, MD, assistant professor of pediatrics at the Kaiser Permanente Bernard J. Tyson School of Medicine, Pasadena, Calif., COVID-19 has “changed the way pediatric medicine is being practiced.”

Although she works in outpatient pediatric care, she said that routine care “is way down” in this setting as well. Like Dr. Dias, she has witnessed a major increase in the use of telemedicine to reach pediatric patients, but she is very concerned about the large proportion of children who are missing routine care, including vaccinations.

“We were already seeing outbreaks of whooping cough and measles pre COVID, so we are quite worried that we will see more,” Dr. Porter said.

A reduction in demand for care does not have the same immediate effect on revenue at a large health maintenance organization like Kaiser Permanente, but growing unemployment in the general population will mean fewer HMO members. In turn, this could have an impact on the entire system.

“When membership goes down, then it will have implications for how we can provide services,” Dr. Porter said.

In the meantime, social workers at Kaiser Permanente “are tirelessly working” to help parents losing benefits to obtain medicines for sick children with chronic diseases, according to Dr. Porter. She echoed the comments of Dr. Dias in predicting major changes in pediatric care if the COVID-19 pandemic and its economic consequences persist.

The conference was sponsored by the Society of Hospital Medicine, the American Academy of Pediatrics, and the Academic Pediatric Association.

The rapid decline in pediatric hospital visits that came quickly after COVID-19 has emerged as a major public health threat, creating the need for adaptations among those offering hospital-based care, according to an objective look at patient numbers that was presented at the virtual Pediatric Hospital Medicine.

“Pre-COVID, operating margins had already taken a significant decline – and there are lots of different reasons for why this was happening – but a lot of hospitals in the United States were going from seeing about a 5% operating margin to closer to 2% to 3%,” said Magna Dias, MD, medical director, pediatric inpatient services, at Yale New Haven Children’s Hospital, Bridgeport, Conn.

This nearly 50% decline “was already putting pressure on us in the community hospital setting where pediatrics is not necessarily generating a ton of revenue to justify our programs, but post COVID, our operating revenue – and this is a report from May – was down 282%,” Dr. Dias reported.

Dr. Dias said that hundreds of hospitals have furloughed workers in the United States since the pandemic began. Although the job losses are not confined to pediatric care, statistics show that pediatrics is one of the hardest hit specialties.

“Looking specifically at ED [emergency department] visits under age 14, one study showed a 71% to 72% decrease post COVID,” Dr. Dias said. This included a 97% reduction in ED visits for flu and more than an 80% reduction in visits for asthma, otitis media, and nausea or vomiting.

It is not clear when children will return to the hospital in pre-COVID-19 numbers, but it might not be soon if the a second wave of infections follows the first, according to Dr. Dias. She suggested that pediatric hospitalists should be thinking about how to expand their services.

“One thing we are really good at in terms of working in the community hospital is diversification. We are used to working in more than one area and being flexible,” Dr. Dias said. Quoting Charles Darwin, who concluded that adaption to change predicts species survival, Dr. Dias advised pediatric hospitalists to look for new opportunities.

Taking on a broader range of responsibilities will not be a significant leap for many pediatric hospitalists. In a survey conducted several years ago by the American Academy of Pediatrics (AAP), hospital staff pediatricians were associated with activities ranging from work in the neonatal intensive care unit to primary ED coverage, according to Dr. Dias. Now with declining patient volumes on pediatric floors, she foresees an even greater expansion, including the care of young adults.

One organization formed in response to the COVID-19 pandemic, called the Pediatric Overflow Planning Contingency Response Network (POPCoRN) has been taking a lead in guiding the delivery of adult care in a pediatric environment. As a cochair of a community hospital special interest group within POPCoRN, Dr. Dias said she has participated in these discussions.

“At some centers, they have gone from age 18 to 21, some have gone up to age 25, some have gone up to 30 years,” she said.

Many centers are working to leverage telemedicine to reach pediatric patients no longer coming to the hospital, according to Dr. Dias.

“There are a lot of people being very creative in telemedicine,” she said. While it is considered as one way “to keep children at your institution,” Dr. Dias said others are considering how telemedicine might provide new opportunities. For one example, telemedicine might be an opportunity to deliver care in rural hospitals without pediatric services.

Immune checkpoint inhibition was not associated with an increased mortality risk from COVID-19 in patients with cancer in an international observational study.

The study included 113 cancer patients who had laboratory-confirmed COVID-19 within 12 months of receiving immune checkpoint inhibitor therapy. The patients did not receive chemotherapy within 3 months of testing positive for COVID-19.

In all, 33 patients were admitted to the hospital, including 6 who were admitted to the ICU, and 9 patients died.

“Nine out of 113 patients is a mortality rate of 8%, which is in the middle of the earlier reported rates for cancer patients in general [7.6%-12%],” said Aljosja Rogiers, MD, PhD, of the Melanoma Institute Australia in Sydney.

COVID-19 was the primary cause of death in seven of the patients, including three of those who were admitted to the ICU, Dr. Rogiers noted.

He reported these results during the AACR virtual meeting: COVID-19 and Cancer.
 

Study details

Patients in this study were treated at 19 hospitals in North America, Europe, and Australia, and the data cutoff was May 15, 2020. Most patients (64%) were treated in Europe, which was the epicenter for the COVID-19 pandemic at the time of data collection, Dr. Rogiers noted. A third of patients were in North America, and 3% were in Australia.

The patients’ median age was 63 years (range, 27-86 years). Most patients were men (65%), and most had Eastern Cooperative Oncology Group performance scores of 0-1 (90%).

The most common malignancies were melanoma (57%), non–small cell lung cancer (17%), and renal cell carcinoma (9%). Treatment was for early cancer in 26% of patients and for advanced cancer in 74%. Comorbidities included cardiovascular disease in 27% of patients, diabetes in 15%, pulmonary disease in 12%, and renal disease in 5%.

Immunosuppressive therapy equivalent to a prednisone dose of 10 mg or greater daily was given in 13% of patients, and other immunosuppressive therapies, such as infliximab, were given in 3%.

Among the 60% of patients with COVID-19 symptoms, 68% had fever, 59% had cough, 34% had dyspnea, and 15% had myalgia. Most of the 40% of asymptomatic patients were tested because they had COVID-19–positive contact, Dr. Rogiers noted.

Immune checkpoint inhibitor treatment included monotherapy with a programmed death–1/PD–ligand 1 inhibitor in 82% of patients, combination anti-PD-1 and anti-CTLA4 therapy in 13%, and other therapy – usually a checkpoint inhibitor combined with a different type of targeted agent – in 5%.

At the time of COVID-19 diagnosis, 30% of patients had achieved a partial response, complete response, or had no evidence of disease, 18% had stable disease, and 15% had progression. Response data were not available in 37% of cases, usually because treatment was only recently started prior to COVID-19 diagnosis, Dr. Rogiers said.

Treatments administered for COVID-19 included antibiotic therapy in 25% of patients, oxygen therapy in 20%, glucocorticoids in 10%, antiviral drugs in 6%, and intravenous immunoglobulin or anti–interleukin-6 in 2% each.

Among patients admitted to the ICU, 3% required mechanical ventilation, 2% had vasopressin, and 1% received renal replacement therapy.

At the data cutoff, 20 of 33 hospitalized patients (61%) had been discharged, and 4 (12%) were still in the hospital.
 

Mortality results

Nine patients died. The rate of death was 8% overall and 27% among hospitalized patients.

“The mortality rate of COVID-19 in the general population without comorbidities is about 1.4%,” Dr. Rogiers said. “For cancer patients, this is reported to be in the range of 7.6%-12%. To what extent patients on immune checkpoint inhibition are at a higher risk of mortality is currently unknown.”

Theoretically, immune checkpoint inhibition could either mitigate or exacerbate COVID-19 infection. It has been hypothesized that immune checkpoint inhibitors could increase the risk of severe acute lung injury or other complications of COVID-19, Dr. Rogiers said, explaining the rationale for the study.

The study shows that the patients who died had a median age of 72 years (range, 49-81 years), which is slightly higher than the median overall age of 63 years. Six patients were from North America, and three were from Italy.

“Two melanoma patients and two non–small cell lung cancer patients died,” Dr. Rogiers said. He noted that two other deaths were in patients with renal cell carcinoma, and three deaths were in other cancer types. All patients had advanced or metastatic disease.

Given that 57% of patients in the study had melanoma and 17% had NSCLC, this finding may indicate that COVID-19 has a slightly higher mortality rate in NSCLC patients than in melanoma patients, but the numbers are small, Dr. Rogiers said.

Notably, six of the patients who died were not admitted to the ICU. In four cases, this was because of underlying malignancy; in the other two cases, it was because of a constrained health care system, Dr. Rogiers said.

Overall, the findings show that the mortality rate of patients with COVID-19 and cancer treated with immune checkpoint inhibitors is similar to the mortality rate reported in the general cancer population, Dr. Rogiers said.

“Treatment with immune checkpoint inhibition does not seem to pose an additional mortality risk for cancer patients with COVID-19,” he concluded.

Dr. Rogiers reported having no conflicts of interest. There was no funding disclosed for the study.

Among women who have a coincidental appendectomy during surgery for chronic pelvic pain or endometriosis, about 15% have appendiceal endometriosis confirmed by pathological examination, according to a study.

“In the women with appendiceal endometriosis, only 26% had an appendix that looked abnormal,” said Whitney T. Ross, MD, of the department of obstetrics and gynecology at Penn State Health, Hershey.

The results, presented at the virtual annual scientific meeting of the Society of Gynecologic Surgeons, indicate that “appendiceal endometriosis is common in women receiving surgery for chronic pelvic pain or endometriosis,” she said. “This study and multiple other studies have also demonstrated that coincidental appendectomy is safe.”

The long-term impact of coincidental appendectomy and its effect on quality of life are not known, however, which may make it difficult to weigh the costs and benefits of the procedure, Dr. Ross said. “It is important to talk to patients about this procedure and determine which approach is the right approach for your institution.”

The study of 609 coincidental appendectomies did not include patients with retrocecal appendices, which may confound the true rate of appendiceal endometriosis, commented Saifuddin T. Mama, MD, MPH, of Rowan University, Camden, N.J.

When the investigators started the study, they were not sure of the risks and benefits of the procedure in patients with retrocecal appendices. An anecdotal report from another research group suggests that outcomes with retrocecal appendices may not be significantly different. “But that is certainly an important question and one that we would like to address in a future prospective study,” Dr. Ross said.

Surgeons have debated the role of coincidental appendectomy during gynecologic surgery. Concerns about safety and questions about the prevalence of appendiceal pathology are reasons that coincidental appendectomy has not been more widely adopted. On the other hand, the procedure may benefit patients and aid diagnosis.

To evaluate the role of coincidental appendectomy in the surgical excision of endometriosis, Dr. Ross and colleagues analyzed data from consecutive coincidental appendectomies performed at one institution between 2013 and 2019. They identified cases in a prospectively maintained surgical database to assess safety and the prevalence of appendiceal pathology.

The indication for surgery was chronic pelvic pain but no visualized endometriosis for 42 patients, stage I-II endometriosis for 388 patients, and stage III-IV endometriosis for 179 patients.

Surgeries included laparoscopic hysterectomy (77.5%), operative laparoscopy (19.9%), and laparoscopic trachelectomy (2.6%). Pathological analysis of the appendices identified endometriosis in 14.9%, malignancy in 0.7%, polyps in 0.5%, and appendicitis in 0.3%.

Among women with chronic pelvic pain but no visualized endometriosis, 2.4% had appendiceal endometriosis. Among those with stage I-II endometriosis, 7% had appendiceal endometriosis, and in patients with stage III-IV endometriosis, the rate of appendiceal endometriosis was 35.2%.

In about 6% of patients with appendiceal endometriosis, the appendix was the only site of pathologically confirmed endometriosis.

Compared with chronic pelvic pain, stage III-IV endometriosis was associated with a significantly increased risk of appendiceal endometriosis (odds ratio, 22.2). The likelihood of appendiceal endometriosis also increased when the appendix looked abnormal (odds ratio, 6.5).

The probability of diagnosing appendiceal endometriosis also increases with the number of other locations of confirmed endometriosis.

“Our surgical decision making is based off of intraoperative findings. However, the final gold-standard diagnosis can’t take place until the pathologic specimen is analyzed,” she said. “We also know that there is a significant discordance, as high as 50%, in early-stage endometriosis between visual inspection and pathology findings.”

There were no complications related to the performance of a coincidental appendectomy during surgery or in the 12 weeks after.

Dr. Ross outlined surgeons’ three main options for performing coincidental appendectomy in patients undergoing surgery for chronic pelvic pain or endometriosis: universal coincidental appendectomy, targeted appendectomy based on operative findings, and performing the procedure based on the appearance of the appendix.

Basing the decision on appearance “is going to miss a lot of appendiceal endometriosis,” Dr. Ross said. In the present study, 67 of the 91 cases, about 74%, would have been missed.

Among women who have a coincidental appendectomy during surgery for chronic pelvic pain or endometriosis, about 15% have appendiceal endometriosis confirmed by pathological examination, according to a study.

“In the women with appendiceal endometriosis, only 26% had an appendix that looked abnormal,” said Whitney T. Ross, MD, of the department of obstetrics and gynecology at Penn State Health, Hershey.

The results, presented at the virtual annual scientific meeting of the Society of Gynecologic Surgeons, indicate that “appendiceal endometriosis is common in women receiving surgery for chronic pelvic pain or endometriosis,” she said. “This study and multiple other studies have also demonstrated that coincidental appendectomy is safe.”

The long-term impact of coincidental appendectomy and its effect on quality of life are not known, however, which may make it difficult to weigh the costs and benefits of the procedure, Dr. Ross said. “It is important to talk to patients about this procedure and determine which approach is the right approach for your institution.”

The study of 609 coincidental appendectomies did not include patients with retrocecal appendices, which may confound the true rate of appendiceal endometriosis, commented Saifuddin T. Mama, MD, MPH, of Rowan University, Camden, N.J.

When the investigators started the study, they were not sure of the risks and benefits of the procedure in patients with retrocecal appendices. An anecdotal report from another research group suggests that outcomes with retrocecal appendices may not be significantly different. “But that is certainly an important question and one that we would like to address in a future prospective study,” Dr. Ross said.

Surgeons have debated the role of coincidental appendectomy during gynecologic surgery. Concerns about safety and questions about the prevalence of appendiceal pathology are reasons that coincidental appendectomy has not been more widely adopted. On the other hand, the procedure may benefit patients and aid diagnosis.

To evaluate the role of coincidental appendectomy in the surgical excision of endometriosis, Dr. Ross and colleagues analyzed data from consecutive coincidental appendectomies performed at one institution between 2013 and 2019. They identified cases in a prospectively maintained surgical database to assess safety and the prevalence of appendiceal pathology.

The indication for surgery was chronic pelvic pain but no visualized endometriosis for 42 patients, stage I-II endometriosis for 388 patients, and stage III-IV endometriosis for 179 patients.

Surgeries included laparoscopic hysterectomy (77.5%), operative laparoscopy (19.9%), and laparoscopic trachelectomy (2.6%). Pathological analysis of the appendices identified endometriosis in 14.9%, malignancy in 0.7%, polyps in 0.5%, and appendicitis in 0.3%.

Among women with chronic pelvic pain but no visualized endometriosis, 2.4% had appendiceal endometriosis. Among those with stage I-II endometriosis, 7% had appendiceal endometriosis, and in patients with stage III-IV endometriosis, the rate of appendiceal endometriosis was 35.2%.

In about 6% of patients with appendiceal endometriosis, the appendix was the only site of pathologically confirmed endometriosis.

Compared with chronic pelvic pain, stage III-IV endometriosis was associated with a significantly increased risk of appendiceal endometriosis (odds ratio, 22.2). The likelihood of appendiceal endometriosis also increased when the appendix looked abnormal (odds ratio, 6.5).

The probability of diagnosing appendiceal endometriosis also increases with the number of other locations of confirmed endometriosis.

“Our surgical decision making is based off of intraoperative findings. However, the final gold-standard diagnosis can’t take place until the pathologic specimen is analyzed,” she said. “We also know that there is a significant discordance, as high as 50%, in early-stage endometriosis between visual inspection and pathology findings.”

There were no complications related to the performance of a coincidental appendectomy during surgery or in the 12 weeks after.

Dr. Ross outlined surgeons’ three main options for performing coincidental appendectomy in patients undergoing surgery for chronic pelvic pain or endometriosis: universal coincidental appendectomy, targeted appendectomy based on operative findings, and performing the procedure based on the appearance of the appendix.

Basing the decision on appearance “is going to miss a lot of appendiceal endometriosis,” Dr. Ross said. In the present study, 67 of the 91 cases, about 74%, would have been missed.

First responders to the World Trade Center (WTC) attacks on Sept. 11, 2001, who have cognitive impairment show cortical thinning across multiple brain regions, including those commonly affected by Alzheimer’s disease, suggest results from the first structural neuroimaging study conducted in this population. The study clarifies that a neurodegenerative condition is present in first responders who experience cognitive impairment in midlife, which “is incredibly important to know,” said lead author Sean Clouston, PhD, of Stony Brook (N.Y.) University.

The findings were presented at the virtual annual meeting of the Alzheimer’s Association International Conference and were published online in Alzheimer’s and Dementia: Diagnosis, Assessment and Disease Monitoring.
 

Brain atrophy in midlife

During the 9/11 attack and in its aftermath, WTC responders were exposed to a range of inhaled neurotoxicants, as well as extreme psychosocial stressors. A growing number of WTC responders who are now in their 50s and early 60s are experiencing early cognitive impairment.

Using MRI, the investigators examined cortical thickness (CTX), a surrogate marker for neurodegeneration, in 99 mostly male WTC responders; 48 had cognitive impairment, and 51 did not. The age range of the participants was 45 to 65 years, a range during which cortical atrophy is uncommon in the general population, the researchers noted.

Compared with cognitively normal responders, those with cognitive impairment were found to have reductions in CTX across the whole brain and across 21 of 34 cortical regions, including frontal, temporal, and occipital lobes.

In both cognitively impaired and cognitively unimpaired WTC responders, CTX was reduced in the entorhinal and temporal cortices compared with normative data, but reductions were greater with cognitive impairment. Posttraumatic distress disorder (PTSD) status was not predictive of a reduction in CTX across groups.

Dr. Clouston said the level of reduction in CTX in many responders is similar to that commonly found in patients with dementia and may reflect early-stage dementia occurring in midlife.

Limitations of the study include the small sample size, the cross-sectional design, the unique nature of the exposure, and a lack of a non-WTC external control group.
 

‘Illuminating’ study

Keith N. Fargo, PhD, director of scientific engagement for the Alzheimer’s Association, called the findings “interesting and illuminating” but cautioned that it is not possible to show cause and effect with this type of study.

“We also don’t know when cortical thinning might have started or how quickly it might be progressing,” Dr. Fargo said in an interview.

He noted that the pattern of cortical thinning is “somewhat consistent with what we see among people who live with high levels of air pollution, which is an emerging risk factor for Alzheimer’s disease and other dementias.”

The Lancet Commission on Dementia Prevention, Intervention, and Care added air pollution to its list of modifiable risk factors for dementia, which was recently updated.

Clinicians “need to be aware that their middle-aged 9/11 first responders are at a higher risk level for cognitive impairment, as well as PTSD and depression,” Dr. Fargo said.

The study was funded by the Centers for Disease Control and Prevention and the National Institute on Aging. Dr. Clouston and Dr. Fargo have reported no relevant financial relationships.

People living with HIV who put on extra pounds and develop metabolic syndrome or related disorders linked in part to certain antiretroviral agents remain a concern today, even as the drugs used to suppress HIV infection have evolved over the decades.

Linkage of HIV treatment with lipodystrophy and insulin resistance or diabetes began in the 1990s with protease inhibitors (Clin Infect Dis. 2000 Jun;30[suppl 2]:s135-42). Several reports over the years also tied any form of effective antiretroviral therapy to weight gain in HIV patients (Antivir Ther. 2012;17[7]:1281-9). More recently, reports have rattled the HIV-treatment community by associating alarmingly high levels of weight gain with a useful and relatively new drug, tenofovir alafenamide fumarate (TAF) – a nucleoside reverse transcriptase inhibitor (NRTI) approved for use in the United States in late 2016, as well as certain agents from an entirely different antiretroviral therapy (ART) class, the integrase strand transfer inhibitors (INSTIs). Both TAF and the INSTIs have come to play major roles in the HIV-treatment landscape, despite relevant and concerning recent weight gain observations with these drugs, such as in a 2019 meta-analysis of eight trials with 5,680 treatment-naive patients who started ART during 2003-2015 (Clin Infect Dis. 2019 Oct 14;doi: 10.1093/cid/ciz999).

“Weight gain is clearly seen in studies of dolutegravir [DTG] or bictegravir [BTG] with TAF,” wrote W.D. Francois Venter, PhD and Andrew Hill, PhD in a recent published commentary on the topic (Lancet HIV. 2020 Jun 1;7[6]:e389-400). Both DTG and BTG are INSTI class members.

“Excessive weight gain, defined as more than 10% over baseline, has recently been observed among people with HIV initiating or switching to regimens incorporating TAF, an INSTI, or both, particularly DTG,” wrote Jordan E. Lake, MD, an HIV specialist at the University of Texas Health Science Center at Houston, in a recent commentary posted online. Women and Black patients “are at even greater risk for excessive weight gain,” Dr. Lake added.

“In recent times, it has emerged that weight gain is more pronounced with the integrase inhibitor class of agents, especially dolutegravir and bictegravir, the so-called second-generation” INSTIs, said Anna Maria Geretti, MD, a professor of clinical infection, microbiology, and immunology at the University of Liverpool, England. ”The effect is more pronounced in women and people of non-White ethnicity, and is of concern because of the associated potential risk of metabolic syndrome, cardiovascular disease, etc.,” Dr. Geretti said in an interview.

The unprecedented susceptibility to weight gain seen recently in non-White women may in part have resulted from the tendency of many earlier treatment trials to have cohorts comprised predominantly of White men, Dr. Venter noted in an interview.
 

Alarming weight gains reported

Perhaps the most eye-popping example of the potential for weight gain with the combination of TAF with an INSTI came in a recent report from the ADVANCE trial, a randomized, head-to-head comparison of three regimens in 1,053 HIV patients in South Africa. After 144 weeks on a regimen of TAF (Vemlidy), DTG (Tivicay), and FTC (emtricitabine, Emtriva), another NRTI, women gained an averaged of more than 12 kg, compared with their baseline weight, significantly more than in two comparator groups, Simiso Sokhela, MB, reported at the virtual meeting of the International AIDS conference. The women in ADVANCE on the TAF-DTG-FTC regimen also had an 11% rate of incident metabolic syndrome during their first 96 weeks on treatment, compared with rates of 8% among patients on a different form of tenofovir, tenofovir disoproxil fumarate (TDF), along with DTG-FTC, and 5% among those on TDF–EFV (efavirenz, Sustiva)–FTC said Dr. Sokhela, an HIV researcher at Ezintsha, a division of the University of the Witwatersrand in Johannesburg, South Africa.

“We believe that these results support the World Health Organization guidelines that reserve TAF for only patients with osteoporosis or impaired renal function,” Dr. Sokhela said during a press briefing at the conference. The WHO guidelines list the first-line regimen as TDF-DTG-3TC (lamivudine; Epivir) or FTC. “The risk for becoming obese continued to increase after 96 weeks” of chronic use of these drugs, she added.

“All regimens are now brilliant at viral control. Finding the ones that don’t make patients obese or have other long-term side effects is now the priority,” noted Dr. Venter, a professor and HIV researcher at University of the Witwatersrand, head of Ezintsha, and lead investigator of ADVANCE. Clinicians and researchers have recently thought that combining TAF and an INSTI plus FTC or a similar NRTI “would be the ultimate regimen to replace the nonnucleoside reverse transcriptase inhibitors (NNRTIs)” such as EFV, “but now we have a major headache” with unexpectedly high weight gains in some patients, Dr. Venter said.

Weight gains “over 10 kg are unlikely to be acceptable in any circumstances, especially when starting body mass index is already borderline overweight,” wrote Dr. Venter along with Dr. Hill in their commentary. Until recently, many clinicians chalked up weight gain on newly begun ART as a manifestation of the patient’s “return-to-health,” but this interpretation “gives a positive spin to a potentially serious and common side effect,” they added.
 

More from ADVANCE

The primary efficacy endpoint of ADVANCE was suppression of viral load to less than 50 RNA copies/mL after 48 weeks on treatment, and the result showed that the TAF-DTG-FTC regimen and the TDF-DTG-FTC regimen were each noninferior to the control regimen of TDF-EFV-FTC (New Engl J Med. 2019 Aug 29;381[9]:803-15). Virtually all of the enrolled patients were Black, and 59% were women. Planned follow-up of all patients ran for 96 weeks. After 48 weeks, weight gain among the women averaged 6.4 kg, 3.2 kg, and 1.7 kg in the TAF-DTG, TDF-DTG, and TDF-EFV arms respectively. After 96 weeks, the average weight gains among women were 8.2 kg, 4.6 kg, and 3.2 kg, respectively, in new results reported by Dr. Sokhela at the IAC. Follow-up to 144 weeks was partial and included about a quarter of the enrolled women, with gains averaging 12.3 kg, 7.4 kg, and 5.5 kg respectively. The pattern of weight gain among men tracked the pattern in women, but the magnitude of gain was less. Among men followed for 144 weeks, average gain among those on TAF-DTG-FTC was 7.2 kg, the largest gain seen among men on any regimen and at any follow-up time in the study.

Dr. Sokhela also reported data on body composition analyses, which showed that the weight gains were largely in fat rather than lean tissue, fat accumulation was significantly greater in women than men, and that in both sexes fat accumulated roughly equally in the trunk and on limbs.

An additional analysis looked at the incidence of new-onset obesity among the women who had a normal body mass index at baseline. After 96 weeks, incident obesity occurred in 14% of women on the TAG-DTG-FTC regimen, 8% on TDF-DTG-FTC, and in 2% of women maintained on TDF-EFV-FTC, said Dr. Hill in a separate report at the conference.
 

Weight starts to weigh in

“I am very mindful of weight gain potential, and I talk to patients about it. It doesn’t determine what regimen I choose for a patient” right now, “but it’s only a matter of time before it starts influencing what we do, particularly if we can achieve efficacy with fewer drugs,” commented Babafemi O. Taiwo, MD, professor of medicine and chief of infectious diseases at Northwestern University in Chicago. “I’ve had some patients show up with a weight gain of 20 kg, and that shouldn’t happen,” he said during a recent online educational session. Dr. Taiwo said his recent practice has been to warn patients about possible weight gain and to urge them to get back in touch with him quickly if it happens.

“Virologic suppression is the most important goal with ART, and the U.S. Department of Health and Human Services currently recommends INSTI-based ART for most PWH [people with HIV],” wrote Dr. Lake in April 2020. “I counsel all PWH initiating ART about the potential for weight gain, and I discuss their current diet and healthy lifestyle habits. I explain to patients that we will monitor their weight, and if weight gain seems more than either of us are comfortable with then we will reassess. Only a small percentage of patients experience excessive weight gain after starting ART.” Dr. Lake also stressed that she had not yet begun to change the regimen a patient is on solely because of weight gain. “We do not know whether this weight gain is reversible,” she noted.

“I do not anticipate that a risk of weight gain at present will dictate a change in guidelines,” said Dr. Geretti. “Drugs such as dolutegravir and bictegravir are very effective, and they are unlikely to cause drug resistance. Further data on the mechanism of weight gain and the reversibility after a change of treatment will help refine drug selection in the near future,” she predicted.

“I consider weight gain when prescribing because my patients hear about this. It’s a side effect that my patients really care about, and I don’t blame them,” said Lisa Hightow-Weidman, MD, a professor and HIV specialist at the University of North Carolina at Chapel Hill, during an on-line educational session. “If you don’t discuss it with a patient and then weight gain happens and the patient finds out [the known risk from their treatment] they may have an issue,” she noted. But weight gain is not a reason to avoid these drugs. “They are great medications in many ways, with once-daily regimens and few side effects.”
 

Weight gain during pregnancy a special concern

An additional analysis of data from ADVANCE presented at the conference highlighted what the observed weight gain on ART could mean for women who become pregnant while on treatment. Based on a systematic literature review, the ADVANCE investigators calculated the relative risk for six obesity-related pregnancy complications, compared with nonobese women: preterm delivery, gestational diabetes, gestational hypertension, preeclampsia, postpartum hemorrhage, and caesarean delivery. Based on the obesity changes among women on their assigned ART in ADVANCE, the researchers calculated the predicted incidence of these six complications. The analysis showed that for every 1,000 women, those on TAG-DTG-FTC would have an excess of 53 obesity-related pregnancy complications, those on TDF-DTG-FTC would develop 28 excess pregnancy complications, and those on TDG-EFV-FTC would have four excess complications, reported Dr. Hill at the International AIDS conference.

The researchers also ran a similar simulation for the incidence of neonatal complications that could result when mothers are obese because of their ART. The six neonatal complications included in this analysis were small for gestational age, large for gestational age, macrosomia, neonatal death, stillbirth, and neural tube defects. Based on the excess rate of incident obesity, they calculated that for every 1,000 pregnancies women on TAD-DTG-FTC would have 24 additional infants born with one of these complications, women on TDF-DTG-FTC would have an excess of 13 of these events, and women on TDG-EFV-FTC would have an excess of three such obesity-related neonatal complications, Dr. Hill said.
 

Sorting out the drugs

Results from several additional studies reported at the conference have started trying to discern exactly which ART drugs and regimens pose the greatest weight gain risk and which have the least risk while retaining high efficacy and resistance barriers.

Further evidence implicating any type of ART as a driver of increased weight came from a review of 8,256 adults infected with HIV and members of the Kaiser Permanente health system in three U.S. regions during 2000-2016. Researchers matched these cases using several demographic factors with just under 130,000 members without HIV. Those infected by HIV had half the prevalence of obesity as the matched controls at baseline. During 12 years of follow-up, those infected with HIV had a threefold higher rate of weight gain than those who were uninfected. Annual weight gain averaged 0.06 kg/year among the uninfected people and 0.22 kg/year among those infected with HIV, a statistically significant difference that was consistent regardless of whether people started the study at a normal body mass index, overweight, or obese, reported Michael J. Silverberg, PhD, an epidemiologist with Kaiser Permanente in Oakland, Calif.

Another study tried to focus on the weight gain impact when patients on three-drug ART regimens changed from taking TDF to TAF. This analysis used data collected in the OPERA (Observational Pharmaco-Epidemiology Research & Analysis) longitudinal cohort of about 115,000 U.S. PWH. The observational cohort included nearly 7,000 patients who made a TDF-to-TAF switch, including 3,288 patients who maintained treatment during this switch with an INSTI, 1,454 who maintained a background regimen based on a NNRTI, 1,430 patients who also switched from an INSTI to a different drug, and 747 patients maintained on a boosted dose of a protease inhibitor. All patients were well controlled on their baseline regimen, with at least two consecutive measures showing undetectable viral load.

Patients who maintained their background regimens while changing from TDF to TAF had a 2.0-2.6 kg increase in weight during the 9 months immediately following their switch to TAF, reported Patrick Mallon, MB, a professor of microbial diseases at University College Dublin. Among the patients who both switched to TAF and also switched to treatment with an INSTI, weight gain during the 9 months after the switch averaged 2.6-4.5 kg, depending on which INSTI was started. Patients who switched to treatment with elvitegravir/cobicistat (an INSTI plus a boosting agent) averaged a gain of 2.6 kg during 9 months, those who switched to DTG averaged a 3.1-kg gain, and those who switched to BTG averaged a 4.6-kg increase, Dr. Mallon reported at the conference.

These findings “give us a good sense that the weight gain is real. This is not just overeating or not exercising, but weight changes coincidental with a change in HIV treatment,” commented David Wohl, MD, professor of medicine and site leader of the HIV Prevention and Treatment Clinical Trials Unit at the University of North Carolina at Chapel Hill, during an online educational session.

Contrary to this evidence suggesting a consistent uptick in weight when patients start TAF treatment was a recent report on 629 HIV patients randomized to treatment with TAF-BTG-FTC or abacavir (an NRTI, Ziagen)–DTG-3TC, which found similar weight gains between these two regimens after 144 weeks on treatment (Lancet HIV. 2020 Jun;7[6]:e389-400). This finding had the effect of “strengthening the argument that TAF is simply an innocent bystander” and does not play a central role in weight gain, and supporting the notion that the alternative tenofovir formulation, TDF, differs from TAF by promoting weight loss, Dr. Venter and Dr. Hill suggested in their commentary that accompanied this report.

The new findings from Dr. Mallon raise “serious questions about the way we have moved to TAF as a replacement for TDF, especially because the benefits [from TAF] are for a small subgroup – patients with renal disease or osteoporosis,” Dr. Venter said in an interview. “The question is, will we see weight gain like this” if TAF was combined with a non-INSTI drug? he wondered.

While some study results have suggested a mitigating effect from TDF on weight gain, that wasn’t the case in the AFRICOS (African Cohort Study) study of 1,954 PWH who started treatment with TDF-DTG-FTC (742 patients) or a different three-drug regimen. After a median of 225 days on treatment, those who started on TDF-DTG-FTC had an adjusted, 85% higher rate of developing a high body mass index, compared with patients on a different ART regimen, Julie Ake, MD, reported in a talk at the conference. Her conclusion focused on the possible involvement of DTG: “Consistent with previous reports, dolutegravir was significantly associated with an increased risk of developing high body mass index,” said Dr. Ake, director of the U.S. Military HIV Research Program in Bethesda, Md. and leader of AFRICOS.

A potential workaround to some drugs that cause excessive the weight gain is to just not use them. That was part of the rationale for the TANGO study, which took 741 HIV-infected patients with successful viral suppression on a regimen of TAF-FTC plus one or two additional agents and switched half of them to a TAF-less, two-drug regimen of DTG-FTC. This open-label study’s primary endpoint was noninferiority for viral suppression of the DTG-FTC regimen, compared with patients who stayed on their starting regimen, and the results proved that DTG-FTC was just as effective over 48 weeks for this outcome (Clin Infect Dis. 2020 Jan 6. doi: 10.1093/cid/ciz1243).

At the conference, TANGO’s lead investigator, Jean van Wyk, MD, reported the weight and metabolic effects of the switch. The results showed a similar and small weight gain (on average less than 1 kg) during 48 week follow-up regardless of whether patients remained on their baseline, TAF-containing regimen or switched to DTG-FTC, said Dr. van Wyk, global medical lead for HIV treatment at Viiv Healthcare, the company that markets DTG. About three-quarters of patients in both arms received “boosted” dosages of their drugs, and in this subgroup, patients on DTG-FTC showed statistically significant benefits in several lipid levels, fasting glucose level, and in their degree of insulin resistance. Dr. van Wyk said. These between-group differences were not statistically significant among the “unboosted” patients, and the results failed to show a significant between-group difference in the incidence of metabolic syndrome.

Dr. Venter called these results “exciting,” and noted that he already uses the DTG-FTC two-drug combination “a lot” to treat PWH and renal disease.

A second alternative regimen showcased in a talk at the conference used the three-drug regimen of TDF-FTC plus the NNRTI, DOR (doravirine, Pifeltro). The DRIVE-SHIFT trial enrolled 670 HIV patients with successfully suppressed viral load on conventional regimens who were either switched to TDF-DOR-FTC or maintained on their baseline treatment. After 48 weeks, results confirmed the primary efficacy endpoint of noninferiority for maintenance of suppression with the investigational regimen (J Acquir Immune Defic Syndr. 2019 Aug;81[4]:463-72).

A post-hoc analysis looked at weight changes among these patients after as much as 144 weeks of follow-up. The results showed that patients switched to TDF-DOR-FTC had an average weight increase of 1.2-1.4 kg after more than 2 years on the new regimen, with fewer than 10% of patients having a 10% or greater weight gain with DOR, a “next-generation” NNRTI, reported Princy N. Kumar, MD, professor at Georgetown University and chief of infectious diseases at MedStar Georgetown University Hospital in Washington. “Weight gain was minimal, even over the long term,” she noted.

The tested DOR-based regimen also looks “very exciting,” but the populations it’s been tested have also been largely limited to White men, and limited data exist about the regimen’s performance in pregnant women, commented Dr. Venter. The DRIVE-SHIRT patient cohort was about 85% men, and about three-quarters White.

More weight data needed

HIV-treatment researchers and clinicians seem agreed that weight gain and other metabolic effects from HIV treatment need more assessment and evidence because current data, while suggestive, is also inconclusive.

“Clinical trials are desperately needed to understand the mechanisms of and potential therapeutic options for excessive weight gain on ART,” wrote Dr. Lake in her commentary in April. “While more research is needed,” the new data reported at the virtual International AIDS conference “get us closer to understanding the effects of integrase inhibitors and TAF on weight and the potential metabolic consequences,” she commented as chair of the conference session where these reports occurred.

“Further data on the mechanism of weight gain and its reversibility after a change of treatment will help refine drug selection in the near future,” predicted Dr. Geretti.

“It’s hard to understand physiologically how drugs from such different classes all seem to have weight effects; it’s maddening,” said Dr. Venter. “We need decent studies in all patient populations. That will now be the priority,” he declared. “Patients shouldn’t have to choose” between drugs that most effectively control their HIV infection and drugs that don’t pose a risk for weight gain or metabolic derangements. PWH “should not have to face obesity as their new epidemic,” he wrote with Dr. Hill.

People living with HIV who put on extra pounds and develop metabolic syndrome or related disorders linked in part to certain antiretroviral agents remain a concern today, even as the drugs used to suppress HIV infection have evolved over the decades.

Linkage of HIV treatment with lipodystrophy and insulin resistance or diabetes began in the 1990s with protease inhibitors (Clin Infect Dis. 2000 Jun;30[suppl 2]:s135-42). Several reports over the years also tied any form of effective antiretroviral therapy to weight gain in HIV patients (Antivir Ther. 2012;17[7]:1281-9). More recently, reports have rattled the HIV-treatment community by associating alarmingly high levels of weight gain with a useful and relatively new drug, tenofovir alafenamide fumarate (TAF) – a nucleoside reverse transcriptase inhibitor (NRTI) approved for use in the United States in late 2016, as well as certain agents from an entirely different antiretroviral therapy (ART) class, the integrase strand transfer inhibitors (INSTIs). Both TAF and the INSTIs have come to play major roles in the HIV-treatment landscape, despite relevant and concerning recent weight gain observations with these drugs, such as in a 2019 meta-analysis of eight trials with 5,680 treatment-naive patients who started ART during 2003-2015 (Clin Infect Dis. 2019 Oct 14;doi: 10.1093/cid/ciz999).

“Weight gain is clearly seen in studies of dolutegravir [DTG] or bictegravir [BTG] with TAF,” wrote W.D. Francois Venter, PhD and Andrew Hill, PhD in a recent published commentary on the topic (Lancet HIV. 2020 Jun 1;7[6]:e389-400). Both DTG and BTG are INSTI class members.

“Excessive weight gain, defined as more than 10% over baseline, has recently been observed among people with HIV initiating or switching to regimens incorporating TAF, an INSTI, or both, particularly DTG,” wrote Jordan E. Lake, MD, an HIV specialist at the University of Texas Health Science Center at Houston, in a recent commentary posted online. Women and Black patients “are at even greater risk for excessive weight gain,” Dr. Lake added.

“In recent times, it has emerged that weight gain is more pronounced with the integrase inhibitor class of agents, especially dolutegravir and bictegravir, the so-called second-generation” INSTIs, said Anna Maria Geretti, MD, a professor of clinical infection, microbiology, and immunology at the University of Liverpool, England. ”The effect is more pronounced in women and people of non-White ethnicity, and is of concern because of the associated potential risk of metabolic syndrome, cardiovascular disease, etc.,” Dr. Geretti said in an interview.

The unprecedented susceptibility to weight gain seen recently in non-White women may in part have resulted from the tendency of many earlier treatment trials to have cohorts comprised predominantly of White men, Dr. Venter noted in an interview.
 

Alarming weight gains reported

Perhaps the most eye-popping example of the potential for weight gain with the combination of TAF with an INSTI came in a recent report from the ADVANCE trial, a randomized, head-to-head comparison of three regimens in 1,053 HIV patients in South Africa. After 144 weeks on a regimen of TAF (Vemlidy), DTG (Tivicay), and FTC (emtricitabine, Emtriva), another NRTI, women gained an averaged of more than 12 kg, compared with their baseline weight, significantly more than in two comparator groups, Simiso Sokhela, MB, reported at the virtual meeting of the International AIDS conference. The women in ADVANCE on the TAF-DTG-FTC regimen also had an 11% rate of incident metabolic syndrome during their first 96 weeks on treatment, compared with rates of 8% among patients on a different form of tenofovir, tenofovir disoproxil fumarate (TDF), along with DTG-FTC, and 5% among those on TDF–EFV (efavirenz, Sustiva)–FTC said Dr. Sokhela, an HIV researcher at Ezintsha, a division of the University of the Witwatersrand in Johannesburg, South Africa.

“We believe that these results support the World Health Organization guidelines that reserve TAF for only patients with osteoporosis or impaired renal function,” Dr. Sokhela said during a press briefing at the conference. The WHO guidelines list the first-line regimen as TDF-DTG-3TC (lamivudine; Epivir) or FTC. “The risk for becoming obese continued to increase after 96 weeks” of chronic use of these drugs, she added.

“All regimens are now brilliant at viral control. Finding the ones that don’t make patients obese or have other long-term side effects is now the priority,” noted Dr. Venter, a professor and HIV researcher at University of the Witwatersrand, head of Ezintsha, and lead investigator of ADVANCE. Clinicians and researchers have recently thought that combining TAF and an INSTI plus FTC or a similar NRTI “would be the ultimate regimen to replace the nonnucleoside reverse transcriptase inhibitors (NNRTIs)” such as EFV, “but now we have a major headache” with unexpectedly high weight gains in some patients, Dr. Venter said.

Weight gains “over 10 kg are unlikely to be acceptable in any circumstances, especially when starting body mass index is already borderline overweight,” wrote Dr. Venter along with Dr. Hill in their commentary. Until recently, many clinicians chalked up weight gain on newly begun ART as a manifestation of the patient’s “return-to-health,” but this interpretation “gives a positive spin to a potentially serious and common side effect,” they added.
 

More from ADVANCE

The primary efficacy endpoint of ADVANCE was suppression of viral load to less than 50 RNA copies/mL after 48 weeks on treatment, and the result showed that the TAF-DTG-FTC regimen and the TDF-DTG-FTC regimen were each noninferior to the control regimen of TDF-EFV-FTC (New Engl J Med. 2019 Aug 29;381[9]:803-15). Virtually all of the enrolled patients were Black, and 59% were women. Planned follow-up of all patients ran for 96 weeks. After 48 weeks, weight gain among the women averaged 6.4 kg, 3.2 kg, and 1.7 kg in the TAF-DTG, TDF-DTG, and TDF-EFV arms respectively. After 96 weeks, the average weight gains among women were 8.2 kg, 4.6 kg, and 3.2 kg, respectively, in new results reported by Dr. Sokhela at the IAC. Follow-up to 144 weeks was partial and included about a quarter of the enrolled women, with gains averaging 12.3 kg, 7.4 kg, and 5.5 kg respectively. The pattern of weight gain among men tracked the pattern in women, but the magnitude of gain was less. Among men followed for 144 weeks, average gain among those on TAF-DTG-FTC was 7.2 kg, the largest gain seen among men on any regimen and at any follow-up time in the study.

Dr. Sokhela also reported data on body composition analyses, which showed that the weight gains were largely in fat rather than lean tissue, fat accumulation was significantly greater in women than men, and that in both sexes fat accumulated roughly equally in the trunk and on limbs.

An additional analysis looked at the incidence of new-onset obesity among the women who had a normal body mass index at baseline. After 96 weeks, incident obesity occurred in 14% of women on the TAG-DTG-FTC regimen, 8% on TDF-DTG-FTC, and in 2% of women maintained on TDF-EFV-FTC, said Dr. Hill in a separate report at the conference.
 

Weight starts to weigh in

“I am very mindful of weight gain potential, and I talk to patients about it. It doesn’t determine what regimen I choose for a patient” right now, “but it’s only a matter of time before it starts influencing what we do, particularly if we can achieve efficacy with fewer drugs,” commented Babafemi O. Taiwo, MD, professor of medicine and chief of infectious diseases at Northwestern University in Chicago. “I’ve had some patients show up with a weight gain of 20 kg, and that shouldn’t happen,” he said during a recent online educational session. Dr. Taiwo said his recent practice has been to warn patients about possible weight gain and to urge them to get back in touch with him quickly if it happens.

“Virologic suppression is the most important goal with ART, and the U.S. Department of Health and Human Services currently recommends INSTI-based ART for most PWH [people with HIV],” wrote Dr. Lake in April 2020. “I counsel all PWH initiating ART about the potential for weight gain, and I discuss their current diet and healthy lifestyle habits. I explain to patients that we will monitor their weight, and if weight gain seems more than either of us are comfortable with then we will reassess. Only a small percentage of patients experience excessive weight gain after starting ART.” Dr. Lake also stressed that she had not yet begun to change the regimen a patient is on solely because of weight gain. “We do not know whether this weight gain is reversible,” she noted.

“I do not anticipate that a risk of weight gain at present will dictate a change in guidelines,” said Dr. Geretti. “Drugs such as dolutegravir and bictegravir are very effective, and they are unlikely to cause drug resistance. Further data on the mechanism of weight gain and the reversibility after a change of treatment will help refine drug selection in the near future,” she predicted.

“I consider weight gain when prescribing because my patients hear about this. It’s a side effect that my patients really care about, and I don’t blame them,” said Lisa Hightow-Weidman, MD, a professor and HIV specialist at the University of North Carolina at Chapel Hill, during an on-line educational session. “If you don’t discuss it with a patient and then weight gain happens and the patient finds out [the known risk from their treatment] they may have an issue,” she noted. But weight gain is not a reason to avoid these drugs. “They are great medications in many ways, with once-daily regimens and few side effects.”
 

Weight gain during pregnancy a special concern

An additional analysis of data from ADVANCE presented at the conference highlighted what the observed weight gain on ART could mean for women who become pregnant while on treatment. Based on a systematic literature review, the ADVANCE investigators calculated the relative risk for six obesity-related pregnancy complications, compared with nonobese women: preterm delivery, gestational diabetes, gestational hypertension, preeclampsia, postpartum hemorrhage, and caesarean delivery. Based on the obesity changes among women on their assigned ART in ADVANCE, the researchers calculated the predicted incidence of these six complications. The analysis showed that for every 1,000 women, those on TAG-DTG-FTC would have an excess of 53 obesity-related pregnancy complications, those on TDF-DTG-FTC would develop 28 excess pregnancy complications, and those on TDG-EFV-FTC would have four excess complications, reported Dr. Hill at the International AIDS conference.

The researchers also ran a similar simulation for the incidence of neonatal complications that could result when mothers are obese because of their ART. The six neonatal complications included in this analysis were small for gestational age, large for gestational age, macrosomia, neonatal death, stillbirth, and neural tube defects. Based on the excess rate of incident obesity, they calculated that for every 1,000 pregnancies women on TAD-DTG-FTC would have 24 additional infants born with one of these complications, women on TDF-DTG-FTC would have an excess of 13 of these events, and women on TDG-EFV-FTC would have an excess of three such obesity-related neonatal complications, Dr. Hill said.
 

Sorting out the drugs

Results from several additional studies reported at the conference have started trying to discern exactly which ART drugs and regimens pose the greatest weight gain risk and which have the least risk while retaining high efficacy and resistance barriers.

Further evidence implicating any type of ART as a driver of increased weight came from a review of 8,256 adults infected with HIV and members of the Kaiser Permanente health system in three U.S. regions during 2000-2016. Researchers matched these cases using several demographic factors with just under 130,000 members without HIV. Those infected by HIV had half the prevalence of obesity as the matched controls at baseline. During 12 years of follow-up, those infected with HIV had a threefold higher rate of weight gain than those who were uninfected. Annual weight gain averaged 0.06 kg/year among the uninfected people and 0.22 kg/year among those infected with HIV, a statistically significant difference that was consistent regardless of whether people started the study at a normal body mass index, overweight, or obese, reported Michael J. Silverberg, PhD, an epidemiologist with Kaiser Permanente in Oakland, Calif.

Another study tried to focus on the weight gain impact when patients on three-drug ART regimens changed from taking TDF to TAF. This analysis used data collected in the OPERA (Observational Pharmaco-Epidemiology Research & Analysis) longitudinal cohort of about 115,000 U.S. PWH. The observational cohort included nearly 7,000 patients who made a TDF-to-TAF switch, including 3,288 patients who maintained treatment during this switch with an INSTI, 1,454 who maintained a background regimen based on a NNRTI, 1,430 patients who also switched from an INSTI to a different drug, and 747 patients maintained on a boosted dose of a protease inhibitor. All patients were well controlled on their baseline regimen, with at least two consecutive measures showing undetectable viral load.

Patients who maintained their background regimens while changing from TDF to TAF had a 2.0-2.6 kg increase in weight during the 9 months immediately following their switch to TAF, reported Patrick Mallon, MB, a professor of microbial diseases at University College Dublin. Among the patients who both switched to TAF and also switched to treatment with an INSTI, weight gain during the 9 months after the switch averaged 2.6-4.5 kg, depending on which INSTI was started. Patients who switched to treatment with elvitegravir/cobicistat (an INSTI plus a boosting agent) averaged a gain of 2.6 kg during 9 months, those who switched to DTG averaged a 3.1-kg gain, and those who switched to BTG averaged a 4.6-kg increase, Dr. Mallon reported at the conference.

These findings “give us a good sense that the weight gain is real. This is not just overeating or not exercising, but weight changes coincidental with a change in HIV treatment,” commented David Wohl, MD, professor of medicine and site leader of the HIV Prevention and Treatment Clinical Trials Unit at the University of North Carolina at Chapel Hill, during an online educational session.

Contrary to this evidence suggesting a consistent uptick in weight when patients start TAF treatment was a recent report on 629 HIV patients randomized to treatment with TAF-BTG-FTC or abacavir (an NRTI, Ziagen)–DTG-3TC, which found similar weight gains between these two regimens after 144 weeks on treatment (Lancet HIV. 2020 Jun;7[6]:e389-400).

The new findings from Dr. Mallon raise “serious questions about the way we have moved to TAF as a replacement for TDF, especially because the benefits [from TAF] are for a small subgroup – patients with renal disease or osteoporosis,” Dr. Venter said in an interview. “The question is, will we see weight gain like this” if TAF was combined with a non-INSTI drug? he wondered.

The WHO guidelines list the first-line regimen as TDF-DTG-3TC (lamivudine; Epivir) or FTC. “The risk for becoming obese continued to increase after 96 weeks” of chronic use of these drugs, she added.

“All regimens are now brilliant at viral control. Finding the ones that don’t make patients obese or have other long-term side effects is now the priority,” noted Dr. Venter, a professor and HIV researcher at University of the Witwatersrand, head of Ezintsha, and lead investigator of ADVANCE. Clinicians and researchers have recently thought that combining TAF and an INSTI plus FTC or a similar NRTI “would be the ultimate regimen to replace the nonnucleoside reverse transcriptase inhibitors (NNRTIs)” such as EFV, “but now we have a major headache” with unexpectedly high weight gains in some patients, Dr. Venter said.

Weight gains “over 10 kg are unlikely to be acceptable in any circumstances, especially when starting body mass index is already borderline overweight,” wrote Dr. Venter along with Dr. Hill in their commentary. Until recently, many clinicians chalked up weight gain on newly begun ART as a manifestation of the patient’s “return-to-health,” but this interpretation “gives a positive spin to a potentially serious and common side effect,” they added.
 

More from ADVANCE

The primary efficacy endpoint of ADVANCE was suppression of viral load to less than 50 RNA copies/mL after 48 weeks on treatment, and the result showed that the TAF-DTG-FTC regimen and the TDF-DTG-FTC regimen were each noninferior to the control regimen of TDF-EFV-FTC (New Engl J Med. 2019 Aug 29;381[9]:803-15). Virtually all of the enrolled patients were Black, and 59% were women. Planned follow-up of all patients ran for 96 weeks. After 48 weeks, weight gain among the women averaged 6.4 kg, 3.2 kg, and 1.7 kg in the TAF-DTG, TDF-DTG, and TDF-EFV arms respectively. After 96 weeks, the average weight gains among women were 8.2 kg, 4.6 kg, and 3.2 kg, respectively, in new results reported by Dr. Sokhela at the IAC. Follow-up to 144 weeks was partial and included about a quarter of the enrolled women, with gains averaging 12.3 kg, 7.4 kg, and 5.5 kg respectively. The pattern of weight gain among men tracked the pattern in women, but the magnitude of gain was less. Among men followed for 144 weeks, average gain among those on TAF-DTG-FTC was 7.2 kg, the largest gain seen among men on any regimen and at any follow-up time in the study.

Dr. Sokhela also reported data on body composition analyses, which showed that the weight gains were largely in fat rather than lean tissue, fat accumulation was significantly greater in women than men, and that in both sexes fat accumulated roughly equally in the trunk and on limbs.

An additional analysis looked at the incidence of new-onset obesity among the women who had a normal body mass index at baseline. After 96 weeks, incident obesity occurred in 14% of women on the TAG-DTG-FTC regimen, 8% on TDF-DTG-FTC, and in 2% of women maintained on TDF-EFV-FTC, said Dr. Hill in a separate report at the conference.
 

Weight starts to weigh in

“I am very mindful of weight gain potential, and I talk to patients about it. It doesn’t determine what regimen I choose for a patient” right now, “but it’s only a matter of time before it starts influencing what we do, particularly if we can achieve efficacy with fewer drugs,” commented Babafemi O. Taiwo, MD, professor of medicine and chief of infectious diseases at Northwestern University in Chicago. “I’ve had some patients show up with a weight gain of 20 kg, and that shouldn’t happen,” he said during a recent online educational session. Dr. Taiwo said his recent practice has been to warn patients about possible weight gain and to urge them to get back in touch with him quickly if it happens.

“Virologic suppression is the most important goal with ART, and the U.S. Department of Health and Human Services currently recommends INSTI-based ART for most PWH [people with HIV],” wrote Dr. Lake in April 2020. “I counsel all PWH initiating ART about the potential for weight gain, and I discuss their current diet and healthy lifestyle habits. I explain to patients that we will monitor their weight, and if weight gain seems more than either of us are comfortable with then we will reassess. Only a small percentage of patients experience excessive weight gain after starting ART.” Dr. Lake also stressed that she had not yet begun to change the regimen a patient is on solely because of weight gain. “We do not know whether this weight gain is reversible,” she noted.

“I do not anticipate that a risk of weight gain at present will dictate a change in guidelines,” said Dr. Geretti. “Drugs such as dolutegravir and bictegravir are very effective, and they are unlikely to cause drug resistance. Further data on the mechanism of weight gain and the reversibility after a change of treatment will help refine drug selection in the near future,” she predicted.

“I consider weight gain when prescribing because my patients hear about this. It’s a side effect that my patients really care about, and I don’t blame them,” said Lisa Hightow-Weidman, MD, a professor and HIV specialist at the University of North Carolina at Chapel Hill, during an on-line educational session. “If you don’t discuss it with a patient and then weight gain happens and the patient finds out [the known risk from their treatment] they may have an issue,” she noted. But weight gain is not a reason to avoid these drugs. “They are great medications in many ways, with once-daily regimens and few side effects.”
 

Weight gain during pregnancy a special concern

An additional analysis of data from ADVANCE presented at the conference highlighted what the observed weight gain on ART could mean for women who become pregnant while on treatment. Based on a systematic literature review, the ADVANCE investigators calculated the relative risk for six obesity-related pregnancy complications, compared with nonobese women: preterm delivery, gestational diabetes, gestational hypertension, preeclampsia, postpartum hemorrhage, and caesarean delivery. Based on the obesity changes among women on their assigned ART in ADVANCE, the researchers calculated the predicted incidence of these six complications. The analysis showed that for every 1,000 women, those on TAG-DTG-FTC would have an excess of 53 obesity-related pregnancy complications, those on TDF-DTG-FTC would develop 28 excess pregnancy complications, and those on TDG-EFV-FTC would have four excess complications, reported Dr. Hill at the International AIDS conference.

The researchers also ran a similar simulation for the incidence of neonatal complications that could result when mothers are obese because of their ART. The six neonatal complications included in this analysis were small for gestational age, large for gestational age, macrosomia, neonatal death, stillbirth, and neural tube defects. Based on the excess rate of incident obesity, they calculated that for every 1,000 pregnancies women on TAD-DTG-FTC would have 24 additional infants born with one of these complications, women on TDF-DTG-FTC would have an excess of 13 of these events, and women on TDG-EFV-FTC would have an excess of three such obesity-related neonatal complications, Dr. Hill said.
 

Sorting out the drugs

Results from several additional studies reported at the conference have started trying to discern exactly which ART drugs and regimens pose the greatest weight gain risk and which have the least risk while retaining high efficacy and resistance barriers.

Further evidence implicating any type of ART as a driver of increased weight came from a review of 8,256 adults infected with HIV and members of the Kaiser Permanente health system in three U.S. regions during 2000-2016. Researchers matched these cases using several demographic factors with just under 130,000 members without HIV. Those infected by HIV had half the prevalence of obesity as the matched controls at baseline. During 12 years of follow-up, those infected with HIV had a threefold higher rate of weight gain than those who were uninfected. Annual weight gain averaged 0.06 kg/year among the uninfected people and 0.22 kg/year among those infected with HIV, a statistically significant difference that was consistent regardless of whether people started the study at a normal body mass index, overweight, or obese, reported Michael J. Silverberg, PhD, an epidemiologist with Kaiser Permanente in Oakland, Calif.

Another study tried to focus on the weight gain impact when patients on three-drug ART regimens changed from taking TDF to TAF. This analysis used data collected in the OPERA (Observational Pharmaco-Epidemiology Research & Analysis) longitudinal cohort of about 115,000 U.S. PWH. The observational cohort included nearly 7,000 patients who made a TDF-to-TAF switch, including 3,288 patients who maintained treatment during this switch with an INSTI, 1,454 who maintained a background regimen based on a NNRTI, 1,430 patients who also switched from an INSTI to a different drug, and 747 patients maintained on a boosted dose of a protease inhibitor. All patients were well controlled on their baseline regimen, with at least two consecutive measures showing undetectable viral load.

Patients who maintained their background regimens while changing from TDF to TAF had a 2.0-2.6 kg increase in weight during the 9 months immediately following their switch to TAF, reported Patrick Mallon, MB, a professor of microbial diseases at University College Dublin. Among the patients who both switched to TAF and also switched to treatment with an INSTI, weight gain during the 9 months after the switch averaged 2.6-4.5 kg, depending on which INSTI was started. Patients who switched to treatment with elvitegravir/cobicistat (an INSTI plus a boosting agent) averaged a gain of 2.6 kg during 9 months, those who switched to DTG averaged a 3.1-kg gain, and those who switched to BTG averaged a 4.6-kg increase, Dr. Mallon reported at the conference.

These findings “give us a good sense that the weight gain is real. This is not just overeating or not exercising, but weight changes coincidental with a change in HIV treatment,” commented David Wohl, MD, professor of medicine and site leader of the HIV Prevention and Treatment Clinical Trials Unit at the University of North Carolina at Chapel Hill, during an online educational session.

Contrary to this evidence suggesting a consistent uptick in weight when patients start TAF treatment was a recent report on 629 HIV patients randomized to treatment with TAF-BTG-FTC or abacavir (an NRTI, Ziagen)–DTG-3TC, which found similar weight gains between these two regimens after 144 weeks on treatment (Lancet HIV. 2020 Jun;7[6]:e389-400). This finding had the effect of “strengthening the argument that TAF is simply an innocent bystander” and does not play a central role in weight gain, and supporting the notion that the alternative tenofovir formulation, TDF, differs from TAF by promoting weight loss, Dr. Venter and Dr. Hill suggested in their commentary that accompanied this report.

The new findings from Dr. Mallon raise “serious questions about the way we have moved to TAF as a replacement for TDF, especially because the benefits [from TAF] are for a small subgroup – patients with renal disease or osteoporosis,” Dr. Venter said in an interview. “The question is, will we see weight gain like this” if TAF was combined with a non-INSTI drug? he wondered.

While some study results have suggested a mitigating effect from TDF on weight gain, that wasn’t the case in the AFRICOS (African Cohort Study) study of 1,954 PWH who started treatment with TDF-DTG-FTC (742 patients) or a different three-drug regimen. After a median of 225 days on treatment, those who started on TDF-DTG-FTC had an adjusted, 85% higher rate of developing a high body mass index, compared with patients on a different ART regimen, Julie Ake, MD, reported in a talk at the conference. Her conclusion focused on the possible involvement of DTG: “Consistent with previous reports, dolutegravir was significantly associated with an increased risk of developing high body mass index,” said Dr. Ake, director of the U.S. Military HIV Research Program in Bethesda, Md. and leader of AFRICOS.

A potential workaround to some drugs that cause excessive the weight gain is to just not use them. That was part of the rationale for the TANGO study, which took 741 HIV-infected patients with successful viral suppression on a regimen of TAF-FTC plus one or two additional agents and switched half of them to a TAF-less, two-drug regimen of DTG-FTC. This open-label study’s primary endpoint was noninferiority for viral suppression of the DTG-FTC regimen, compared with patients who stayed on their starting regimen, and the results proved that DTG-FTC was just as effective over 48 weeks for this outcome (Clin Infect Dis. 2020 Jan 6. doi: 10.1093/cid/ciz1243).

At the conference, TANGO’s lead investigator, Jean van Wyk, MD, reported the weight and metabolic effects of the switch. The results showed a similar and small weight gain (on average less than 1 kg) during 48 week follow-up regardless of whether patients remained on their baseline, TAF-containing regimen or switched to DTG-FTC, said Dr. van Wyk, global medical lead for HIV treatment at Viiv Healthcare, the company that markets DTG. About three-quarters of patients in both arms received “boosted” dosages of their drugs, and in this subgroup, patients on DTG-FTC showed statistically significant benefits in several lipid levels, fasting glucose level, and in their degree of insulin resistance. Dr. van Wyk said. These between-group differences were not statistically significant among the “unboosted” patients, and the results failed to show a significant between-group difference in the incidence of metabolic syndrome.

Dr. Venter called these results “exciting,” and noted that he already uses the DTG-FTC two-drug combination “a lot” to treat PWH and renal disease.

A second alternative regimen showcased in a talk at the conference used the three-drug regimen of TDF-FTC plus the NNRTI, DOR (doravirine, Pifeltro). The DRIVE-SHIFT trial enrolled 670 HIV patients with successfully suppressed viral load on conventional regimens who were either switched to TDF-DOR-FTC or maintained on their baseline treatment. After 48 weeks, results confirmed the primary efficacy endpoint of noninferiority for maintenance of suppression with the investigational regimen (J Acquir Immune Defic Syndr. 2019 Aug;81[4]:463-72).

A post-hoc analysis looked at weight changes among these patients after as much as 144 weeks of follow-up. The results showed that patients switched to TDF-DOR-FTC had an average weight increase of 1.2-1.4 kg after more than 2 years on the new regimen, with fewer than 10% of patients having a 10% or greater weight gain with DOR, a “next-generation” NNRTI, reported Princy N. Kumar, MD, professor at Georgetown University and chief of infectious diseases at MedStar Georgetown University Hospital in Washington. “Weight gain was minimal, even over the long term,” she noted.

The tested DOR-based regimen also looks “very exciting,” but the populations it’s been tested have also been largely limited to White men, and limited data exist about the regimen’s performance in pregnant women, commented Dr. Venter. The DRIVE-SHIRT patient cohort was about 85% men, and about three-quarters White.

More weight data needed

HIV-treatment researchers and clinicians seem agreed that weight gain and other metabolic effects from HIV treatment need more assessment and evidence because current data, while suggestive, is also inconclusive.

“Clinical trials are desperately needed to understand the mechanisms of and potential therapeutic options for excessive weight gain on ART,” wrote Dr. Lake in her commentary in April. “While more research is needed,” the new data reported at the virtual International AIDS conference “get us closer to understanding the effects of integrase inhibitors and TAF on weight and the potential metabolic consequences,” she commented as chair of the conference session where these reports occurred.

“Further data on the mechanism of weight gain and its reversibility after a change of treatment will help refine drug selection in the near future,” predicted Dr. Geretti.

“It’s hard to understand physiologically how drugs from such different classes all seem to have weight effects; it’s maddening,” said Dr. Venter. “We need decent studies in all patient populations. That will now be the priority,” he declared. “Patients shouldn’t have to choose” between drugs that most effectively control their HIV infection and drugs that don’t pose a risk for weight gain or metabolic derangements. PWH “should not have to face obesity as their new epidemic,” he wrote with Dr. Hill.

Prostate cancer treatments have significant detrimental effects on patients’ quality of life, and these effects may have been downplayed or not fully appreciated, according to a presentation at the virtual annual congress of the European Association of Urology (EAU).

Results of EUPROMS – the first patient-driven, international, prostate cancer quality of life study – showed that fatigue, insomnia, urinary incontinence, and sexual function were worse with certain types of treatments.

“Quality of life is negatively impacted by any treatment for prostate cancer other than active surveillance,” said André Deschamps, the chairman of the patient advocacy movement Europa Uomo, which conducted the study with support from Erasmus University Medical Center in Rotterdam, the Netherlands.

Active surveillance “should be promoted as the first option for treatment for those men where it can be offered safely,” Mr. Deschamps said when presenting the study at the EAU congress.

The study showed that quality of life related to urinary incontinence was lowest in patients who had undergone radical prostatectomy, and sexual function was greatly affected by radiotherapy. Radiotherapy and chemotherapy had the greatest impact on patients’ levels of fatigue, and chemotherapy was associated with “the worst possible outcomes in quality of life,” Mr. Deschamps said.

Conversely, “reported quality of life scores are the best in patients where the cancer is discovered in an early, curable stage. Hence, efforts toward early detection and awareness are essential to avoid unnecessary deterioration in quality of life,” Mr. Deschamps said.
 

About the survey and respondents

Between August and November 2019, 2,943 prostate cancer patients from 24 European countries completed a web-based survey made available via the Europa Uomo website. The survey took around 20 minutes to complete and used three validated quality of life questionnaires, the EORTC-QLQ-C30, the EQ-5D-5L, and EPIC-26.

“The questionnaires were available in 19 languages, so every patient could answer in their mother tongue,” Mr. Deschamps pointed out, highlighting that this was a Europe-wide survey and was estimated to account for 0.1% of the patient population in Europe.

Countries with the highest number of respondents were Norway (n = 506), Sweden (n = 386), Belgium (n = 339), Germany (n = 253), Netherlands (n = 244), France (n = 234), Denmark (n = 188), the United Kingdom (n = 187), and Poland (n = 109).

The average age of respondents was 70 years at the time of the survey and 64 years at the time of diagnosis. Most patients (82%) were living with a partner.

Two-thirds of patients had received only one treatment for prostate cancer. This was most often radical prostatectomy, external beam radiotherapy, or active surveillance. Among the 22% of patients who had received two treatments, the therapies were most often a combination of surgery and radiotherapy, androgen deprivation therapy (ADT) and radiotherapy or chemotherapy, and active surveillance and surgery.
 

Fatigue and insomnia

According to the EORTC-QLQ-C30 symptoms questionnaire, fatigue and insomnia were particular problems for men with prostate cancer, as denoted by scores of 25 and 24, respectively, out of a possible 100. Low scores are associated with worse fatigue and insomnia.

The researchers focused their attention on how specific cancer treatments might influence fatigue. They found that radiotherapy doubled and chemotherapy tripled the number of patients reporting fatigue, when compared with active surveillance. The incidence of fatigue was 22% (n = 304), 33% (n = 246), and 11% (n = 179), respectively.

As for insomnia, “it’s bit of a mixed view,” Mr. Deschamps said. “We believe that the progression of disease is more important for insomnia. The only thing you can say is that chemotherapy leads to an increase in reported insomnia.”
 

Urinary continence and sexual function

The EPIC-26 questionnaire was used to look at the health-related quality of life domains of urinary and sexual function. Sexual function was the most impacted area.

“We often hear that decline in sexual functioning is a relatively small problem for prostate cancer patients, and the effect on their quality of life should not be exaggerated,” Mr. Deschamps said in a press statement.

“We also hear that prostate cancer is typically a disease of ‘old men,’ implying that the loss of sexual function is less relevant. This survey paints a different picture,” he added.

Higher EPIC-26 scores signify better function. For urinary incontinence, the score was 100/100 for active surveillance but 65/100 when active surveillance was combined with surgery and 71/100 for surgery alone. The combination of surgery and radiotherapy carried a score of 73/100 for urinary incontinence. Radiotherapy on its own had a score of 92/100, suggesting it was the addition of the surgery that was having a significant effect. The score for radiotherapy plus ADT was 100/100, and the score for chemotherapy was 86/100.

Chemotherapy appeared to have the worst effect on sexual function, with a score of just 12/100. Radiotherapy was not far behind at 17/100, and surgery alone was 21/100. When radiotherapy and surgery were combined, the score was 15/100.

Sexual function scores were also low for all the other treatments considered – 18/100 for radiotherapy and ADT, 26/100 for active surveillance and surgery, and 57/100 for active surveillance alone.
 

Implications for practice

“The data collected and the analysis done provide patients and healthcare professionals with a ‘snapshot’ on the impact of treatments based on the experience of fellow patients,” Mr. Deschamps said. “We hope these results will be used to establish and disseminate realistic expectations on the effects of different treatments for prostate cancer on [quality of life].”

“This study is important because it was initiated by patients and meant for patients,” noted Monique Roobol, PhD, professor of decision-making in urology at the Erasmus University Medical Center in Rotterdam, the Netherlands, where the survey data were analyzed.

“The questionnaires were completed unrelated to a hospital visit, which means respondents had more freedom to answer and provide insight into the effect of treatment on quality of life over a longer period,” she added.

“For me, the key point is that, as health care professionals, we have underestimated the impact on the quality of life for patients treated for prostate cancer,” said Hein van Poppel, MD, PhD, of University Hospitals Leuven (Belgium), who chaired the session in which the data were presented.

Arnulf Stenzl, MD, of Tübingen (Germany) University said in a statement that the survey provided valuable information. “It uses the same questionnaires used in standard clinical settings, but it is both qualitatively and quantitatively different to the kind of study usually undertaken, so it needs to be read alongside these previous studies,” Dr. Stenzl said.

There were several strong points, he said, such as the fact that EUPROMS was the largest study of its kind and thus would “reflect the impact of treatment on a wide range of patients, with different health systems.”

As an official EAU spokesperson, Dr. Stenzl added, “We completely agree that early detection and treatment is essential if we are to avoid problems with quality of life later on. It shows that, for many men, quality of life can be poor after most prostate cancer treatment, especially in advanced disease. This message is clear, and we need to listen to the voices of these patients.”

EUPROMS was conducted by Europa Uomo in conjunction with the Erasmus University Medical Centre in Rotterdam, the Netherlands. Funding was received from Bayer, Ipsen, and Janssen. The companies had no influence over any aspect of the study. The commentators did not have conflicts of interest to disclose.

Active surveillance “should be promoted as the first option for treatment for those men where it can be offered safely,” Mr. Deschamps said when presenting the study at the EAU congress.

The study showed that quality of life related to urinary incontinence was lowest in patients who had undergone radical prostatectomy, and sexual function was greatly affected by radiotherapy. Radiotherapy and chemotherapy had the greatest impact on patients’ levels of fatigue, and chemotherapy was associated with “the worst possible outcomes in quality of life,” Mr. Deschamps said.

Conversely, “reported quality of life scores are the best in patients where the cancer is discovered in an early, curable stage. Hence, efforts toward early detection and awareness are essential to avoid unnecessary deterioration in quality of life,” Mr. Deschamps said.
 

About the survey and respondents

Between August and November 2019, 2,943 prostate cancer patients from 24 European countries completed a web-based survey made available via the Europa Uomo website. The survey took around 20 minutes to complete and used three validated quality of life questionnaires, the EORTC-QLQ-C30, the EQ-5D-5L, and EPIC-26.

“The questionnaires were available in 19 languages, so every patient could answer in their mother tongue,” Mr. Deschamps pointed out, highlighting that this was a Europe-wide survey and was estimated to account for 0.1% of the patient population in Europe.

Countries with the highest number of respondents were Norway (n = 506), Sweden (n = 386), Belgium (n = 339), Germany (n = 253), Netherlands (n = 244), France (n = 234), Denmark (n = 188), the United Kingdom (n = 187), and Poland (n = 109).

The average age of respondents was 70 years at the time of the survey and 64 years at the time of diagnosis. Most patients (82%) were living with a partner.

Two-thirds of patients had received only one treatment for prostate cancer. This was most often radical prostatectomy, external beam radiotherapy, or active surveillance. Among the 22% of patients who had received two treatments, the therapies were most often a combination of surgery and radiotherapy, androgen deprivation therapy (ADT) and radiotherapy or chemotherapy, and active surveillance and surgery.
 

Fatigue and insomnia

According to the EORTC-QLQ-C30 symptoms questionnaire, fatigue and insomnia were particular problems for men with prostate cancer, as denoted by scores of 25 and 24, respectively, out of a possible 100. Low scores are associated with worse fatigue and insomnia.

The researchers focused their attention on how specific cancer treatments might influence fatigue. They found that radiotherapy doubled and chemotherapy tripled the number of patients reporting fatigue, when compared with active surveillance. The incidence of fatigue was 22% (n = 304), 33% (n = 246), and 11% (n = 179), respectively.

As for insomnia, “it’s bit of a mixed view,” Mr. Deschamps said. “We believe that the progression of disease is more important for insomnia. The only thing you can say is that chemotherapy leads to an increase in reported insomnia.”
 

Urinary continence and sexual function

The EPIC-26 questionnaire was used to look at the health-related quality of life domains of urinary and sexual function. Sexual function was the most impacted area.

“We often hear that decline in sexual functioning is a relatively small problem for prostate cancer patients, and the effect on their quality of life should not be exaggerated,” Mr. Deschamps said in a press statement.

“We also hear that prostate cancer is typically a disease of ‘old men,’ implying that the loss of sexual function is less relevant. This survey paints a different picture,” he added.

Higher EPIC-26 scores signify better function. For urinary incontinence, the score was 100/100 for active surveillance but 65/100 when active surveillance was combined with surgery and 71/100 for surgery alone. The combination of surgery and radiotherapy carried a score of 73/100 for urinary incontinence. Radiotherapy on its own had a score of 92/100, suggesting it was the addition of the surgery that was having a significant effect. The score for radiotherapy plus ADT was 100/100, and the score for chemotherapy was 86/100.

Chemotherapy appeared to have the worst effect on sexual function, with a score of just 12/100. Radiotherapy was not far behind at 17/100, and surgery alone was 21/100. When radiotherapy and surgery were combined, the score was 15/100.

Sexual function scores were also low for all the other treatments considered – 18/100 for radiotherapy and ADT, 26/100 for active surveillance and surgery, and 57/100 for active surveillance alone.
 

Implications for practice

“The data collected and the analysis done provide patients and healthcare professionals with a ‘snapshot’ on the impact of treatments based on the experience of fellow patients,” Mr. Deschamps said. “We hope these results will be used to establish and disseminate realistic expectations on the effects of different treatments for prostate cancer on [quality of life].”

“This study is important because it was initiated by patients and meant for patients,” noted Monique Roobol, PhD, professor of decision-making in urology at the Erasmus University Medical Center in Rotterdam, the Netherlands, where the survey data were analyzed.

“The questionnaires were completed unrelated to a hospital visit, which means respondents had more freedom to answer and provide insight into the effect of treatment on quality of life over a longer period,” she added.

“For me, the key point is that, as health care professionals, we have underestimated the impact on the quality of life for patients treated for prostate cancer,” said Hein van Poppel, MD, PhD, of University Hospitals Leuven (Belgium), who chaired the session in which the data were presented.

Arnulf Stenzl, MD, of Tübingen (Germany) University said in a statement that the survey provided valuable information. “It uses the same questionnaires used in standard clinical settings, but it is both qualitatively and quantitatively different to the kind of study usually undertaken, so it needs to be read alongside these previous studies,” Dr. Stenzl said.

There were several strong points, he said, such as the fact that EUPROMS was the largest study of its kind and thus would “reflect the impact of treatment on a wide range of patients, with different health systems.”

As an official EAU spokesperson, Dr. Stenzl added, “We completely agree that early detection and treatment is essential if we are to avoid problems with quality of life later on. It shows that, for many men, quality of life can be poor after most prostate cancer treatment, especially in advanced disease. This message is clear, and we need to listen to the voices of these patients.”

EUPROMS was conducted by Europa Uomo in conjunction with the Erasmus University Medical Centre in Rotterdam, the Netherlands. Funding was received from Bayer, Ipsen, and Janssen. The companies had no influence over any aspect of the study. The commentators did not have conflicts of interest to disclose.

Perioperative bleeding risk was not associated with platelet count in a fairly large cohort of patients with liver cirrhosis, according to a review of cases, including some involving severe thrombocytopenia.

The findings raise questions about current recommendations that call for transfusing platelet concentrates to reduce bleeding risk during surgery in cirrhosis patients with extremely low platelet counts, Gian Marco Podda, MD, PhD, said at the International Society on Thrombosis and Haemostasis virtual congress.

The overall rate of perioperative bleeding was 8.9% in 996 patients who underwent excision of hepatocellular carcinoma by resection (42%) or radiofrequency ablation (58%) without platelet transfusion between 1998 and 2018. The rates were slightly higher among 65 patients with platelet count of fewer than 50 × 10⁹/L indicating severe thrombocytopenia, and in 292 patients with counts of 50-100 × 10⁹/L, indicating moderate thrombocytopenia (10.8% and 10.2%, respectively), compared with those with a platelet count of higher than 100 × 10⁹/L (8.1%), but the differences were not statistically significant, said Dr. Podda of the University of Milan (Italy).

The corresponding rates among those who underwent radiofrequency ablation were 8.6%, 5.9%, and 5%, and among those who underwent resection, they were 18.8%, 17.7%, and 15.9%.

On multivariate analysis, factors associated with an increased incidence of major bleeding were low hemoglobin level (odds ratio, 0.57), age over 65 years (OR, 1.19), aspartate aminotransferase level greater than twice the upper limit of normal (OR, 2.12), hepatitis B or C cirrhosis versus cryptogenic cirrhosis (OR, 0.08), and resection versus radiofrequency ablation (OR, 3.74), he noted. Logistic regression analysis showed no significant association between platelet count and major bleeding events.

Mortality, a secondary outcome measure, was significantly higher among those with moderate or severe thrombocytopenia (rate of 5.5% for each), compared with those with mild or no thrombocytopenia (2.4%), Dr. Podda said.

Factors associated with mortality on multivariate analysis were severe liver dysfunction as demonstrated by Model for End-Stage Liver Disease score of 10 or greater versus less than 10 (OR, 3.13) and Child-Pugh B and C score versus Child-Pugh A score (OR, 16.72), advanced tumor status as measured by Barcelona-Clínic Liver Cancer staging greater than A4 versus A1 (OR, 5.78), major bleeding (OR, 4.59), and resection versus radiofrequency ablation (OR, 3.31).

“Low platelet count was associated with an increased risk of mortality at 3 months. However, this association disappeared at the multivariate analysis, which took into account markers of severity of liver cirrhosis,” he said.

Dr. Podda and his colleagues conducted the study in light of a recommendation from a consensus conference of the Italian Association for the Study of Liver Disease and the Italian Society of Internal Medicine that called for increasing platelet count by platelet transfusions in patients with cirrhosis who undergo an invasive procedure and who have a platelet count lower than 50 × 10⁹/L.

“This recommendation mostly stemmed from consideration of biological plausibility prospects rather than being based on hard experimental evidence,” he explained, noting that such severe thrombocytopenia affects about 10% of patients with liver cirrhosis.

Based on the findings of this study, the practice is not supported, he concluded.

Most interventional cardiologists still rely solely upon angiography in making revascularization decisions about intermediate stenoses in the setting of stable coronary artery disease – and in doing so they end up making the wrong call nearly 40% of the time, according to the results of an international survey presented at the virtual annual meeting of the European Association of Percutaneous Cardiovascular Interventions.

“We saw a strong tendency to visually overestimate the percent diameter stenosis,” reported Gabor G. Toth, MD, an interventional cardiologist at the Medical University of Graz (Austria).

The same tendency has been highlighted in numerous randomized trials and observational studies. That’s why both European and U.S. guidelines now strongly recommend invasive functional assessment, such as fractional-flow reserve (FFR) testing, in evaluating the significance of intermediate stenoses in the absence of noninvasive evidence of ischemia. The new survey findings point to an important disconnect between these guideline recommendations and current clinical practice, he noted.

Dr. Toth presented the results of the second web-based, international survey on interventional decision-making strategy sponsored by the European Association of Percutaneous Cardiovascular Interventions. He contrasted the findings with those of the previously reported first international online survey, conducted 6 years earlier, for which he was first author (Circ Cardiovasc Interv. 2014 Dec;7[6]:751-9).

The two surveys were identically designed. In both, participants answered questions that enabled investigators to place them into one of four categories based upon the extent of their experience in interventional cardiology. The participants were also presented with 5 angiograms of focal intermediate stenoses and asked to determine the stenosis significance of each lesion. No information on the functional significance of the stenoses was included; however, the respondents could request additional diagnostic information by “ordering” adjunctive invasive functional assessment tests, including FFR, quantitative coronary angiography, intravascular ultrasound, or optical coherence tomography. Importantly, participating cardiologists were asked to make their decisions based upon best possible clinical practice in a hypothetical scenario where financial constraints had no role.

The second international survey was conducted during the latter half of 2019. The 334 interventional cardiologists who responded performed a total of 978 case evaluations including 2,054 coronary lesion assessments.

About 59% of all decisions were made solely on the basis of angiographic appearance without any information as to the functional significance of a given stenosis: Indeed, 13% of all stenoses were thereby declared to be “certainly” nonsignificant, and 46% were deemed “certainly” significant. In total, that figure was down significantly from the 71% rate in the first survey. In the first survey, 47% of decisions based upon angiographic appearance alone were discordant with FFR results known to the investigators, compared with a 39% discordance rate in the second survey.

Of the physician decisions made in the second survey, 10% involved a request for intravascular imaging, essentially unchanged from the 9% rate in the first survey. However, there was a significant increase over time in requests for invasive functional assessment tests: 25% in the first survey, rising to 31% in the second. This increase was entirely driven by additional requests for data on nonhyperemic pressure ratios; there was no difference in requests for FFR testing between the 2013 and 2019 surveys.

Clinician experience played an interesting role in decision-making: “Experience does not have an impact on the accuracy of angiographically based decisions, but experience does have an impact on understanding the need for adjunctive functional diagnostic testing,” Dr. Toth explained.

Indeed, 21% of decisions made by the least-experienced interventional cardiologists involved a request for adjunctive invasive functional assessment, compared with 24% of decisions by physicians in the third quartile of experience, 32% in the second, and 37% of decisions made by the most experienced clinicians.

Discussant Michael Haude, MD, PhD, said that “these results clearly show that eyeball angioguidance is still the dominant tool used in decision-making, and that this eyeball angioguidance continuously overestimates the stenosis when you compare the results to quantitative coronary angiography.

“These results, surprisingly for me, show a quite low uptake of the invasive functional assessments despite overwhelming scientific data leading to clear guideline-based recommendations. Why is this the case, even after financial constraints are ruled out? Probably because FFR is still a complex invasive procedure. Maybe, in the future, quantitative flow-ratio angiography [which requires no pressure wire] or CT-based FFR will be more popular,” said Dr. Haude, an interventional cardiologist at the Rheinland Clinic in Neuss, Germany.

He reported receiving research grants from Biotronik and serving as a paid consultant to that company as well as Cardiac Dimensions, Orbus Neich, and Philips. Dr. Toth reported having no financial conflicts regarding the international survey.

Polycystic ovarian syndrome (PCOS) was associated with a nearly doubled risk of developing psoriasis in a propensity score–matched analysis conducted in Taiwan.

PCOS is characterized by androgen elevation that can lead to insulin resistance and metabolic syndrome, which have also been associated with an increased risk of psoriasis. Previous retrospective analyses have suggested an increased risk of psoriasis associated with PCOS, and psoriasis patients with PCOS have been reported to have more severe skin lesions, compared with those who do not have PCOS.

“The incidence of psoriasis is indeed higher in the PCOS group than in the control group, and the comorbidities related to metabolic syndrome did not modify the adjusted hazard ratio,” said Ming-Li Chen, during her presentation of the study results at the virtual annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis. Dr. Chen is at Chung Shan Medical University in Taiwan.

The researchers analyzed 1 million randomly selected records from Taiwan’s Longitudinal Health Insurance database, a subset of the country’s National Health Insurance Program. Between 2000 and 2012, they identified a case group with at least three outpatient diagnoses or one inpatient diagnosis of PCOS; they then compared each with four patients who did not have PCOS who were matched by age and index year. The mean age in both groups was about 27 years.

The mean follow-up times were 6.99 years for 4,707 cases and 6.94 years for 18,828 controls. Comorbidities were slightly higher in the PCOS group, including asthma (6.7% vs. 4.9%; P less than .001), chronic obstructive pulmonary disease (14% vs. 11%; P less than .001), chronic liver disease (8.0% vs. 5.0%; P less than .001), diabetes mellitus (3.0% vs. 1.4%; P less than .001), hypertension (2.4% vs. 1.5%; P less than .001), hyperlipidemia (5.4% vs. 2.5%; P less than .001), depression (5.4% vs. 3.9%; P less than .001), and sleep apnea (0.23% vs. 0.10%; P = .040).

There was a higher cumulative incidence of psoriasis in the PCOS group (adjusted hazard ratio, 2.07; 95% confidence interval, 1.25-3.44). Other factors associated with increased risk of psoriasis were advanced age (greater than 50 years old; aHR, 14.13; 95% CI, 1.8-110.7) and having a cancer diagnosis (aHR, 11.72; 95% CI, 2.87-47.9).

When PCOS patients were stratified by age, the researchers noted a higher risk of psoriasis among those 20 years or younger (aHR, 4.02; 95% CI, 1.16-13.9) than among those aged 20-50 years (aHR, 1.88; 95% CI, 1.07-3.29). Among those older than 50 years, there was no significantly increased risk, although the number of psoriasis diagnoses and population sizes were small in the latter category. Among patients with PCOS, a cancer diagnosis was not associated with a statistically significant increased risk of psoriasis.

The mechanisms underlying the association between PCOS and psoriasis should be studied further, she noted.

Following Dr. Chen’s prerecorded presentation, there was a live discussion session led by Alice Gottlieb, MD, PhD, medical director of Mount Sinai Beth Israel Dermatology, New York, and Ennio Lubrano, MD, associate professor of rheumatology at the University of Molise (Italy). Dr. Gottlieb noted that the study did not appear to account for weight in the association between PCOS and psoriasis, since heavier people are known to be at greater risk of developing psoriasis. Dr. Chen acknowledged that the study had no records of BMI or weight.

Dr. Gottlieb also wondered if treatment of PCOS led to any improvements in psoriasis in patients with the two diagnoses. “If we treat PCOS, does the psoriasis get better?” Again, the study did not address the question. “We didn’t follow up on therapies,” Dr. Chen said.

Polycystic ovarian syndrome (PCOS) was associated with a nearly doubled risk of developing psoriasis in a propensity score–matched analysis conducted in Taiwan.

PCOS is characterized by androgen elevation that can lead to insulin resistance and metabolic syndrome, which have also been associated with an increased risk of psoriasis. Previous retrospective analyses have suggested an increased risk of psoriasis associated with PCOS, and psoriasis patients with PCOS have been reported to have more severe skin lesions, compared with those who do not have PCOS.

“The incidence of psoriasis is indeed higher in the PCOS group than in the control group, and the comorbidities related to metabolic syndrome did not modify the adjusted hazard ratio,” said Ming-Li Chen, during her presentation of the study results at the virtual annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis. Dr. Chen is at Chung Shan Medical University in Taiwan.

The researchers analyzed 1 million randomly selected records from Taiwan’s Longitudinal Health Insurance database, a subset of the country’s National Health Insurance Program. Between 2000 and 2012, they identified a case group with at least three outpatient diagnoses or one inpatient diagnosis of PCOS; they then compared each with four patients who did not have PCOS who were matched by age and index year. The mean age in both groups was about 27 years.

The mean follow-up times were 6.99 years for 4,707 cases and 6.94 years for 18,828 controls. Comorbidities were slightly higher in the PCOS group, including asthma (6.7% vs. 4.9%; P less than .001), chronic obstructive pulmonary disease (14% vs. 11%; P less than .001), chronic liver disease (8.0% vs. 5.0%; P less than .001), diabetes mellitus (3.0% vs. 1.4%; P less than .001), hypertension (2.4% vs. 1.5%; P less than .001), hyperlipidemia (5.4% vs. 2.5%; P less than .001), depression (5.4% vs. 3.9%; P less than .001), and sleep apnea (0.23% vs. 0.10%; P = .040).
