Clinician Reviews

CHARLOTTE, N.C. – Several factors appear to influence the risk for acute pancreatitis among patients who start taking glucagon-like peptide (GLP-1) receptor agonist medications for weight management, a new study has found.

Type 2 diabetes, advanced chronic kidney disease, and tobacco use were associated with greater risk for acute pancreatitis, researchers report.

On the other hand, a higher body mass index (BMI) – 36 kg/m² or higher – appeared to protect people against developing the condition.

“As this class of medications becomes increasingly popular in the United States, it is important for providers to know which patients are at a higher or lower risk of developing acute pancreatitis after being started on them,” said lead study author Robert Postlethwaite, MD, a gastroenterology resident at the University of Texas Southwestern Medical Center, Dallas.

The findings were presented at the annual meeting of the American College of Gastroenterology in Charlotte, N.C., being held in person and virtually.
 

Popularity comes at a price

The U.S. Food and Drug Administration has approved two GLP-1s for weight management – liraglutide (Victoza) in 2014 and semaglutide (Wegovy) in 2021. They work by targeting areas of the brain that control food intake and appetite. Other GLP-1s approved to treat type 2 diabetes include dulaglutide (Trulicity) and two other formulations of semaglutide (Rybelsus and Ozempic).

The demand for Wegovy has been so great that there is an ongoing shortage of the medication in the United States.

Although GLP-1s demonstrate a favorable side-effect profile, compared with other types of antiobesity medications, acute pancreatitis remains a serious and sometimes life-threatening complication, the researchers note. Some patients require hospitalization.

Dr. Postlethwaite and colleagues performed a retrospective, single-center study of 2,245 patients who attended an academic medical center’s Weight Wellness program from 2015 to 2019. The average age was about 50 years, and 81% were female. The average BMI of all patients was 39.7 kg/m².

The study only included patients starting GLP-1s for treating obesity, not for diabetes.

Of the 2,245 patients, 49 (2.2%) developed acute pancreatitis after starting a GLP-1.

A history of type 2 diabetes mellitus made acute pancreatitis twice as likely (95% confidence interval, 1.04-3.96; P = .04).

Stage 3 or higher chronic kidney disease increased risk 2.3 times (95% CI, 1.18-4.55; P = .01), while tobacco use upped it 3.3 times (95% CI, 1.70-6.50; P < .001).

In contrast, researchers found those with a BMI of 36-40 kg/m² were 88% less likely to develop acute pancreatitis (95% CI, 0.07-0.67; P = .007), compared with patients with a BMI of less than or equal to 30 kg/m². Patients with a BMI of greater than 40 kg/m² had a 73% lower risk (95% CI, 0.10-0.73; P = .01).

Dr. Postlethwaite and colleagues found no association with age, sex, or history of bariatric surgery or acute pancreatitis.

Because a history of acute pancreatitis was not a risk factor, he advised that clinicians not withhold these medications for this reason, “especially given the significant glycemic, cardiovascular, and weight-loss effects.”

“We hope that we can arm clinicians with evidence in order to risk stratify their patients and determine who is at high risk of developing pancreatitis,” Dr. Postlethwaite said.

“Hopefully, we can prevent the development of pancreatitis in some patients, especially high-risk individuals, or at least allow clinicians to be aware of it in higher-risk patients to identify it early enough to prevent complications of acute pancreatitis,” he added.
 

Larger studies needed

The study is “promising,” said session comoderator Baharak Moshiree, MD, a gastroenterologist at Atrium Health, Charlotte, N.C., who was not affiliated with the research.

However, because the study was retrospective and relatively small, it needs to be validated in larger, prospective studies, she added.

“With obesity being such a global issue, there are many patients on these GLP-1 agonists,” Dr. Moshiree said.

Generally, these medications are prescribed by endocrinologists, not gastroenterologists, she noted, and she said that gastroenterologists should be aware of the risks associated with them, including minor gastrointestinal side effects, like nausea and vomiting, that can occur because of delayed gastric emptying.

Dr. Postlethwaite noted that being unable to assess how much alcohol or tobacco individuals used was a limitation. The relatively low proportion of people who developed acute pancreatitis in the study also means larger studies are warranted, he added.

Going forward, Dr. Postlethwaite and colleagues want to study the risks for each individual GLP-1 and other therapies used to control high blood sugar in people with type 2 diabetes, such as DPP4 (dipeptidyl-peptidase 4) inhibitors.

The study was independently supported. Dr. Postlethwaite and Dr. Moshiree report no relevant financial relationships.

Welcome to Impact Factor, your weekly dose of commentary on a new medical study. I’m Dr F. Perry Wilson of the Yale School of Medicine.

It began in a petri dish.

Ivermectin, a widely available, cheap, and well-tolerated drug on the WHO’s list of essential medicines for its critical role in treating river blindness, was shown to dramatically reduce the proliferation of SARS-CoV-2 virus in cell culture.

You know the rest of the story. Despite the fact that the median inhibitory concentration in cell culture is about 100-fold higher than what one can achieve with oral dosing in humans, anecdotal reports of miraculous cures proliferated.

Cohort studies suggested that people who got ivermectin did very well in terms of COVID outcomes.

A narrative started to develop online – one that is still quite present today – that authorities were suppressing the good news about ivermectin in order to line their own pockets and those of the execs at Big Pharma. The official Twitter account of the Food and Drug Administration clapped back, reminding the populace that we are not horses or cows.

And every time a study came out that seemed like the nail in the coffin for the so-called horse paste, it rose again, vampire-like, feasting on the blood of social media outrage.

The truth is that, while excitement for ivermectin mounted online, it crashed quite quickly in scientific circles. Most randomized trials showed no effect of the drug. A couple of larger trials which seemed to show dramatic effects were subsequently shown to be fraudulent.

Then the TOGETHER trial was published. The 1,400-patient study from Brazil, which treated outpatients with COVID-19, found no significant difference in hospitalization or ER visits – the primary outcome – between those randomized to ivermectin vs. placebo or another therapy. 

But still, Brazil. Different population than the United States. Different health systems. And very different rates of Strongyloides infections (this is a parasite that may be incidentally treated by ivermectin, leading to improvement independent of the drug’s effect on COVID). We all wanted a U.S. trial.

And now we have it. ACTIV-6 was published Oct. 21 in JAMA, a study randomizing outpatients with COVID-19 from 93 sites around the United States to ivermectin or placebo.

A total of 1,591 individuals – median age 47, 60% female – with confirmed symptomatic COVID-19 were randomized from June 2021 to February 2022. About half had been vaccinated.

The primary outcome was straightforward: time to clinical recovery. Did ivermectin make people get better, faster?

It did not. The time to recovery, defined as having three symptom-free days, was 12 days in the ivermectin group and 13 days in the placebo group – that’s within the margin of error.

If you had fever, chills, nausea, or other common side effects to the Pfizer/BioNTech and Moderna COVID-19 vaccines, that’s good news.

It means your body had a greater antibody response than people who had just a little pain or rash at the injection site, or no reaction at all.

That’s according to new research published in the journal JAMA Network Open .

“These findings support reframing postvaccination symptoms as signals of vaccine effectiveness and reinforce guidelines for vaccine boosters in older adults,” researchers from Columbia University in New York, the University of Vermont, and Boston University wrote.

The vaccines provided strong protection regardless of the level of reaction, researchers said. Almost all the study’s 928 adult participants had a positive antibody response after receiving two doses of vaccine.

“I don’t want a patient to tell me that, ‘Golly, I didn’t get any reaction, my arm wasn’t sore, I didn’t have fever. The vaccine didn’t work.’ I don’t want that conclusion to be out there,” William Schaffner, MD, a professor in the division of infectious diseases at Vanderbilt University Medical Center, Nashville, Tenn., told CNN.

“This is more to reassure people who have had a reaction that that’s their immune system responding, actually in a rather good way, to the vaccine, even though it has caused them some discomfort,” said Dr. Schaffner, who was not involved in the study.

Vitamin D deficiency increases mortality risk and raising levels even slightly could decrease the risk, researchers examining data from the UK Biobank have found.

They used a Mendelian randomization approach, which uses genetic variants as “proxy indicators” for external factors that affect vitamin D levels, such as sun exposure or dietary intake. It allows for analysis of the relationship between deficiency and outcomes including mortality, which can’t be done in randomized clinical trials for ethical reasons.

Using this method, nutritionist Joshua P. Sutherland, PhD, of the Australian Centre for Precision Health, Adelaide, and colleagues found an association between genetically predicted vitamin D levels [25-(OH)D] and mortality from several major causes, with evidence of causality among people with measured concentrations below, but not above, 50 nmol/L. The findings were published online in Annals of Internal Medicine.

Genetic approach reveals causal relationship

The investigators analyzed data from 307,601 individuals in the UK Biobank, a prospective cohort of people recruited from England, Scotland, and Wales during March 2006 and July 2010. Most were of White European ancestry and were aged 37-73 years at baseline.

Genetically predicted vitamin D levels were estimated using 35 confirmed 25-(OH)D variants. Participants were followed for outcomes up to June 2020.

The average baseline measured 25-(OH)D concentration was 45.2 nmol/L, and 11.7% (n = 36,009) of participants had levels between 10.0  and 24.9 nmol/L. Higher levels were seen in people living in southern areas and nonsmokers as well as those with a higher level of physical activity, less socioeconomic deprivation, and lower body mass index.

During follow-up, 6.1% of participants died (n = 18,700). After adjustment for variables, odds ratios for all causes of mortality were highest among people with 25-(OH)D levels below 25 nmol/L and appeared to plateau between 50 and 75 nmol/L, with no further reduction in mortality at values of 75-125 nmol/L.
 

Mortality 36% higher in those deficient in vitamin D

The risk for mortality was a significant 36% higher for participants with 25-(OH)D 25 nmol/L compared with 50 nmol/L.

With the Mendelian randomization, there was an L-shaped association between genetically predicted 25-(OH)D level and all-cause mortality (P for nonlinearity < .001) and for mortality because of cancer and cardiovascular disease (P for nonlinearity ≤ .033).

Again, the strongest association with those outcomes and genetically predicted 25-(OH)D was found at levels below 25 nmol/L and a plateau was seen by 50 nmol/L.

Compared with a measured 25-(OH)D concentration of 50 nmol/L, investigators estimated that the genetically predicted odds of all-cause mortality would increase sixfold (odds ratio, 6.00) for participants at 10 nmol/L and by 25% (OR, 1.25) for those at 25 nmol/L.

And, compared with a measured 25-(OH)D concentration of 50 nmol/L, those with 10 nmol/L had genetically predicted odds ratios of 5.98 for cardiovascular mortality, 3.37 for cancer mortality, and 12.44 for respiratory mortality.

Comparing measured 25-(OH)D concentrations of 25 nmol/L versus 50 nmol/L, odds ratios for those outcomes were 1.25, 1.16, and 1.96 (95% confidence interval, 1.88-4.67), respectively. All were statistically significant.

Consistent results supportive of a causal effect of genetically predicted 25-(OH)D on all-cause mortality in those with low measured vitamin D concentrations were also found in a sensitivity analysis of 20,837 people of non-White ethnic origin.

The study was funded by the Australian National Health and Medical Research Council. Dr. Sutherland’s studentship is funded by an Australian Research Training Program Scholarship.

Genetic approach reveals causal relationship

The investigators analyzed data from 307,601 individuals in the UK Biobank, a prospective cohort of people recruited from England, Scotland, and Wales during March 2006 and July 2010. Most were of White European ancestry and were aged 37-73 years at baseline.

Genetically predicted vitamin D levels were estimated using 35 confirmed 25-(OH)D variants. Participants were followed for outcomes up to June 2020.

The average baseline measured 25-(OH)D concentration was 45.2 nmol/L, and 11.7% (n = 36,009) of participants had levels between 10.0  and 24.9 nmol/L. Higher levels were seen in people living in southern areas and nonsmokers as well as those with a higher level of physical activity, less socioeconomic deprivation, and lower body mass index.

During follow-up, 6.1% of participants died (n = 18,700). After adjustment for variables, odds ratios for all causes of mortality were highest among people with 25-(OH)D levels below 25 nmol/L and appeared to plateau between 50 and 75 nmol/L, with no further reduction in mortality at values of 75-125 nmol/L.
 

Mortality 36% higher in those deficient in vitamin D

The risk for mortality was a significant 36% higher for participants with 25-(OH)D 25 nmol/L compared with 50 nmol/L.

With the Mendelian randomization, there was an L-shaped association between genetically predicted 25-(OH)D level and all-cause mortality (P for nonlinearity < .001) and for mortality because of cancer and cardiovascular disease (P for nonlinearity ≤ .033).

Again, the strongest association with those outcomes and genetically predicted 25-(OH)D was found at levels below 25 nmol/L and a plateau was seen by 50 nmol/L.

Compared with a measured 25-(OH)D concentration of 50 nmol/L, investigators estimated that the genetically predicted odds of all-cause mortality would increase sixfold (odds ratio, 6.00) for participants at 10 nmol/L and by 25% (OR, 1.25) for those at 25 nmol/L.

And, compared with a measured 25-(OH)D concentration of 50 nmol/L, those with 10 nmol/L had genetically predicted odds ratios of 5.98 for cardiovascular mortality, 3.37 for cancer mortality, and 12.44 for respiratory mortality.

Comparing measured 25-(OH)D concentrations of 25 nmol/L versus 50 nmol/L, odds ratios for those outcomes were 1.25, 1.16, and 1.96 (95% confidence interval, 1.88-4.67), respectively. All were statistically significant.

Consistent results supportive of a causal effect of genetically predicted 25-(OH)D on all-cause mortality in those with low measured vitamin D concentrations were also found in a sensitivity analysis of 20,837 people of non-White ethnic origin.

Vitamin D deficiency increases mortality risk and raising levels even slightly could decrease the risk, researchers examining data from the UK Biobank have found.

They used a Mendelian randomization approach, which uses genetic variants as “proxy indicators” for external factors that affect vitamin D levels, such as sun exposure or dietary intake. It allows for analysis of the relationship between deficiency and outcomes including mortality, which can’t be done in randomized clinical trials for ethical reasons.

Using this method, nutritionist Joshua P. Sutherland, PhD, of the Australian Centre for Precision Health, Adelaide, and colleagues found an association between genetically predicted vitamin D levels [25-(OH)D] and mortality from several major causes, with evidence of causality among people with measured concentrations below, but not above, 50 nmol/L.

The relationship between estrogen levels and heart health makes it particularly important for clinicians to be aware of those patients who might be at risk for cardiovascular disease despite not having other traditional risk factors, according to a presentation Oct. 12 at the North American Menopause Society annual meeting in Atlanta.

”Endogenous estrogens are protective for cardiovascular disease in premenopausal women,” Chrisandra L. Shufelt, MD, chair of the division of general internal medicine and associate director of the Women’s Health Research Center at Mayo Clinic in Jacksonville, Fla., told attendees. Yet, “a substantial population of young women are dying prematurely from cardiovascular disease,” with rates of cardiovascular death increasing in women aged 35-44 even as rates have decreased in postmenopausal women and in men. One potential reason may be premature estrogen loss.

Dr. Shufelt reminded attendees of four major causes of premature estrogen loss: Natural premature menopause, surgical menopause, chemotherapy-induced menopause, and premature ovarian insufficiency. But she would go on to discuss a less widely recognized condition, functional hypothalamic amenorrhea, that also may be contributing to increased cardiovascular risk.

First, Dr. Shufelt reviewed the evidence supporting the relationship between estrogen and cardiovascular health, starting with the Framingham study’s findings that cardiovascular disease is approximately two to four times more common in postmenopausal women than in premenopausal women, depending on the age range.

“Menopause at an early age, particularly under the age of 40, matters,” Dr. Shufelt said. “So we should be discussing this with our patients.”

Surgical menopause makes a difference to cardiovascular health as well, she said. In women under age 35, for example, the risk of a nonfatal heart attack in those with a bilateral oophorectomy was 7.7 times greater than in women who retained both ovaries and their uterus, and 1.5 times greater in women who had a hysterectomy without bilateral oophorectomy.

In a 2019 study, surgical premature menopause was associated with an 87% increased risk of heart disease even after researchers accounted for age, cardiovascular risk factors, and some forms of hormone therapy. The increased risk from natural premature menopause, on the other hand, was lower – a 36% increased risk of heart disease – compared with those producing endogenous hormones. Although randomized controlled trials are unavailable and unlikely to be done, the Nurses’ Health Study and the Danish Nurses Cohort Study, both observational studies, found that heart disease risk was diminished in those taking hormone therapy after surgical premature menopause.

Recommendations for premature or early menopause, from a wide range of different medical societies including NAMS, are that women without contraindications be given estrogen-based hormone therapy until the average age of natural menopause. Though not included in the same guidance, research has also shown that estrogen after oophorectomy does not increase the risk of breast cancer in women with a BRCA1 mutation, Dr. Shufelt said. Hormone therapy for premature or early menopause should adequately replace the levels women have lost and that means younger menopausal women often need higher doses than what older women receive, such as 2 mg/day of oral estradiol rather than the standard doses of 0.5 or 1 mg/day.
 

Functional hypothalamic amenorrhea and cardiovascular risk

Dr. Shufelt then discussed functional hypothalamic amenorrhea (hypogonadotropic hypogonadism), a common type of secondary amenorrhea that affects at least 1.4 million U.S. women. Diagnosis includes lack of a period for at least 3 months in someone who previously menstruated plus lab values below 50 pg/mL for estradiol, below 10 mIU/L for follicle stimulating hormone, and below 10 mIU/L for luteinizing hormone. Causes of this reversible form of infertility can include stress, overexercising, undereating, or some combination of these, plus an underlying genetic predisposition.

“After ruling out polycystic ovary syndrome, prolactinoma, and thyroid dysfunction, clinicians need to consider the diagnosis of hypothalamic amenorrhea,” Dr. Shufelt said. This condition goes beyond low estrogen levels: Women have elevated cortisol, low thyroid levels, low leptin levels, and increased ghrelin.

”This is not going away,” Dr. Shufelt said, sharing data on stress levels among U.S. adults, particularly Gen Z and millennial adults, noting that the ongoing “national mental health crisis” may be contributing to functional hypothalamic amenorrhea.

A 2020 substudy from the Nurses’ Health Study II found an increased risk of premature death in those who didn’t have a period or always had irregular periods starting as early as 14-17 years old. The increased risk of premature death rose with age in those with irregular or absent cycles – a 37% higher risk in 18- to 22-year-olds and a 39% increased risk in 29- to 46-year-olds.

But clinicians aren’t adequately identifying the “phenotype of the hypothalamic women,” Dr. Shufelt said, despite research showing overlap between hypothalamic amenorrhea and a higher risk of cardiovascular disease. Hypothalamic amenorrhea is so understudied that the last original research on the topic was in 2008, Dr. Shufelt said in an interview. ”No research except mine has been done to evaluate heart health in these young women,” she said.

Dr. Shufelt described a study she led involving 30 women with functional hypothalamic amenorrhea, 29 women with normal menstrual cycles, and 30 women who were recently menopausal and not on hormone therapy. The women with hypothalamic amenorrhea had average stress levels but their depression scores were higher than those of the other two groups.

The results showed that women with hypothalamic amenorrhea had lower estradiol and leptin levels and higher testosterone levels compared with the control group, and they had higher cortisol levels than those of both groups. Despite having similar body mass indexes as the control and menopausal groups, women with hypothalamic amenorrhea had lower blood pressure than that of the other two groups, yet they had higher cholesterol levels than those of the control group. EndoPAT^© (Itamar Medical) testing showed that they had poor vascular function.

“In fact, one-third of the women [with hypothalamic amenorrhea] entered the trial with a diagnosis of what would be considered endothelial dysfunction,” Dr. Shufelt said. “Our results demonstrated significantly higher circulating levels of serum proinflammatory cytokines in the women with hypothalamic amenorrhea compared to eumenorrheic controls.”

Dr. Shufelt’s team then tested whether giving estradiol to the women with hypothalamic amenorrhea for 12 weeks would improve their vascular health, but they saw no significant differences between the women who received estrogen and those who received placebo.

“Endothelial function is partly mediated by estrogen, and it was expected that giving back estrogen would ‘fix’ the endothelium, but that is not what happened,” Nanette Santoro, MD, professor and chair of obstetrics and gynecology at the University of Colorado at Denver, Aurora, said in interview. “The mechanisms that maintain vascular function in women are not limited to hormones,” said Dr. Santoro, who was not involved in Dr. Shufelt’s study but attended her lecture. “We need to think beyond the simple model of estrogen-good, no-estrogen-bad.”

Dr. Santoro noted how easy it is to overlook the women who may have cardiovascular risk because of hypothalamic amenorrhea.

“Because many women with functional hypothalamic amenorrhea are super athletic and do not have the typical features of people with cardiometabolic disease – such as glucose intolerance, obesity, abnormal cholesterol or triglycerides, or high blood pressure – clinicians tend to think of them as healthy and to think that simply giving back hormones will fix the problems with bone density and vascular function, but that is not enough,” Dr. Santoro said. “The cognitive-behavioral therapy model for treatment of women with functional hypothalamic amenorrhea addresses the stress-related factors that drive the disorder, and this needs to be considered the standard of care for treatment.”

Stephanie S. Faubion, MD, professor of medicine and director of Mayo Clinic’s Center for Women’s Health in Jacksonville, Fla., who was not involved in Dr. Shufelt’s presentation, also emphasized the importance of recognizing functional hypothalamic amenorrhea.

“This is an underrecognized entity to begin with, and the fact that these women appear to be at increased risk for vascular dysfunction and potentially increased risk for cardiovascular disease down the road makes it even more important for clinicians to identify them and provide interventions early on,” Dr. Faubion said in an interview. “These women need to be identified and the etiology of the amenorrhea addressed, whether it relates to overexercising, being underweight, or experiencing significant stressors that have led to the loss of menstrual cycles.”

Dr. Shufelt’s research was funded by the National Institutes of Health. She had no disclosures. Dr. Santoro is a member of the scientific advisory board for Astellas, Menogenix, Amazon Ember, and Que Oncology, and she consults for Ansh Labs. Dr. Faubion had no disclosures.

MONTREAL – Remote assessment of atopic dermatitis (AD) severity is possible through the use of patient-provided clinical photos – opening a new avenue for improving access for patients, as well as the possibility of conducting remote clinical trials that would be less expensive and less burdensome for participants, according to investigators, who presented the study at the annual meeting of the International Society of Atopic Dermatitis.

Still, practical barriers need to be addressed, particularly the problem of image quality, noted study investigator Aviël Ragamin, MD, from the department of dermatology, Erasmus MC, University Medical Center, Rotterdam, the Netherlands.

“Good-quality images are crucial, [and] in our study, patients didn’t have any incentive to provide images because they had already received their medical consultation,” he explained. He suggested that this problem could be overcome by providing technical support for patients and compensation for trial participants.

The study included 87 children (median age, 7 years), who were assessed for AD severity at an academic outpatient clinic. The in-person visit included assessment with the Eczema Area and Severity Index (EASI) score, as well as the collection of whole-body clinical images. Parents were then asked to return home and to provide their own clinical images and self-administered EASI assessments of their child for comparison. Four raters were asked to rate all images twice and to compare in-clinic and self-administered EASI scores based on the images.

At the in-clinic visit, the median EASI score of the group was 8.8. The majority of patients had moderate (46.6%) or severe (14.8%) AD. Roughly 40% of the patients had darker skin (Fitzpatrick skin types IV–VI).

Using Spearman rank correlation of 1,534 in-clinic and 425 patient-provided images, the study found good inter- and intra-rater reliability for clinical image assessment and strong agreement between images and the in-clinic EASI scores. The top outliers in the assessment were individuals with either darker skin or significant postinflammatory hyperpigmentation, which are “the most difficult cases to rate, based on images,” Dr. Ragamin noted.

There was only moderate correlation between the in-clinic and self-administered EASI scores, with a significant number of patients either underestimating or overestimating their AD severity, he added.

Overall, the main problem with remote assessment seems to be the feasibility of patients providing images, said Dr. Ragamin. Only 36.8% of parents provided any images at all, and of these, 1 of 5 were deemed too blurry, leaving just 13 for final assessment, he explained.

“Pragmatically, it’s tricky,” said Aaron Drucker, MD, a dermatologist at Women’s College Hospital and associate professor at the University of Toronto, who was asked to comment on the study. “It takes long enough to do an EASI score in person, let alone looking through blurry pictures that take too long to load into your electronic medical record. We know it works, but when our hospital went virtual [during the COVID pandemic] ... most of my patients with chronic eczema weren’t even sending me pictures.”

Regarding the utility of remote, full-body photography in clinical practice, he said, “There’s too many feasibility hoops to jump through at this point. The most promise I see is for clinical trials, where it’s hard to get people to come in.”

Dr. Ragamin and Dr. Drucker have disclosed no relevant financial relationships.

MONTREAL – Remote assessment of atopic dermatitis (AD) severity is possible through the use of patient-provided clinical photos – opening a new avenue for improving access for patients, as well as the possibility of conducting remote clinical trials that would be less expensive and less burdensome for participants, according to investigators, who presented the study at the annual meeting of the International Society of Atopic Dermatitis.

Still, practical barriers need to be addressed, particularly the problem of image quality, noted study investigator Aviël Ragamin, MD, from the department of dermatology, Erasmus MC, University Medical Center, Rotterdam, the Netherlands.

“Good-quality images are crucial, [and] in our study, patients didn’t have any incentive to provide images because they had already received their medical consultation,” he explained. He suggested that this problem could be overcome by providing technical support for patients and compensation for trial participants.

A new study shows that Black Americans received ventricular assist devices (VADs) and heart transplants about half as often as White Americans, even when receiving care at an advanced heart failure (HF) center.

The analysis, drawn from 377 patients treated at one of 21 VAD centers in the United States as part of the RIVIVAL study, found that 22.3% of White adults received a heart transplant or VAD, compared with 11% of Black adults.

“That’s what is so concerning to us, that we’re seeing this pattern within this select population. I think it would be too reasonable to hypothesize that it very well could be worse in the general population,” study author Thomas Cascino, MD, MSc, University of Michigan, Ann Arbor, commented.

The study was published online in Circulation: Heart Failure, and it builds on previous work by the researchers, showing that patient preference for early VAD therapy is associated with higher New York Heart Association (NYHA) class and lower income level but not race.

In the present analysis, the number of Black and White participants who said they “definitely or probably” wanted VAD therapy was similar (27% vs. 29%), as was the number wanting “any and all life-sustaining therapies” (74% vs. 65%).

Two-thirds of the cohort was NYHA class III, the average EuroQoL visual analog scale (EQ-VAS) score was 64.6 among the 100 participants who identified as Black and 62.1 in the 277 White participants, and the average age was 58 and 61 years, respectively.

Death rates were also similar during the 2-year follow-up: 18% of Black patients and 13% of White patients.

After controlling for multiple clinical and social determinants of health, including age, Interagency Registry for Mechanically Assisted Circulator Support (INTERMACS) patient profile, EQ-VAS score, and level of education, Black participants had a 55% lower rate of VAD or transplant, compared with White participants (hazard ratio, 0.45; 95% confidence interval, 0.23-0.85). Adding VAD preference to the model did not affect the association.

“Our study suggests that we as providers may be making decisions differently,” Dr. Cascino said. “We can’t say for sure what the reasons are but certainly structural racism, discrimination, and provider biases are the things I worry about.”

“There’s an absolute need for us to look inwards, reflect, and acknowledge that we are likely playing a role in this and then start to be part of the change,” he added.

“The lives disabled or lost are simply too many,” coauthor Wendy Taddei-Peters, PhD, a clinical trials project official at the National Heart, Lung, and Blood Institute, said in an NIH statement. “An immediate step could be to require implicit bias training, particularly for transplant and VAD team members.”

Other suggestions are better tracking of underserved patients and the reasons why they do not receive VAD or become listed for transplant; inclusion of psychosocial components into decision-making about advanced therapy candidacy; and having “disparity experts” join in heart team meetings to help identify biases in real time.

Commenting on the study, Khadijah Breathett, MD, HF/transplant cardiologist and tenured associate professor of medicine, Indiana University Bloomington, said, “I’m glad there’s more push for awareness, because there’s still a population of people that don’t believe this is a real problem.”

Cocaine, methamphetamine, opioids, and cannabis may independently increase risk of atrial fibrillation (AFib), based on data from almost 24 million people.

While more work is needed to uncover causal links, physicians should be aware that these commonly abused substances could be driving new cases of AFib, reported investigators from the University of California, San Francisco.

“Though alcohol and tobacco smoking have each been associated with a heightened risk of [AFib], relationships between other drug use and [AFib] are poorly understood,” they wrote in European Heart Journal.

Some previous studies have ventured into this terrain, but most focused on fatal arrhythmias, or offered anecdotal evidence. This knowledge gap is particularly concerning for cannabis, the researchers noted, as medical and recreational use are on the rise.

American Heart Association

The present analysis included data from 23.5 million adults in California who received care through a hospital, emergency department, or outpatient surgery center during 2005-2015. Based on ICD-9 diagnostic codes, 132,834 of these patients used cannabis, 98,271 used methamphetamines, 48,701 used cocaine, and 10,032 used opiates. Inclusion required lack of AFib at baseline.

Reliance on ICD-9 codes makes the data “quite specific,” but lacking sensitivity, according to principal author Gregory M. Marcus, MD, cardiologist and professor of medicine at UCSF.

“If they were designated as using these drugs, that is very likely true,” Dr. Marcus said in an interview. “But certainly, the absence of any mention of use of these drugs does not exclude the possibility that some people were still using them. That would not create spurious false-positive relationships; if anything, it attenuates existing relationships.”

In other words, using ICD-9 codes reduced the power to detect an association between each drug and AFib, meaning any relationship needed to be sufficiently strong enough to generate a significant result.

At the end of the decade-long study period, 998,747 patients (4.2%) had developed incident AFib. After adjusting for potential confounders and mediators, all four drugs showed significant, independent associations with AFib. Methamphetamines presented the greatest risk (hazard ratio, 1.86%), followed by opiates (HR, 1.74), cocaine (HR, 1.61), and cannabis (HR, 1.35).

“Our findings provide the first evidence utilizing a longitudinal cohort to demonstrate that cannabis use predicts the future onset of AFib,” Dr. Marcus and colleagues wrote.

Dose-response relationships were not detected for any of the substances; however, usage levels were also derived from ICD-9 codes, which may have been insufficient for this purpose, according to the investigators.
 

Causal mechanisms deserve a closer look

Causal links between AFib and each of the drugs remain unclear. Citing prior research, Dr. Marcus and colleagues explained how methamphetamines are capable of “significant cardiac electrical remodeling,” while cocaine may cause sodium channel dysregulation, and opioids can render atrial myocytes more susceptible to oxidative damage. Although cannabis has previously been linked with hospitalization for arrhythmia, a pharmacologic driver of this phenomenon remains largely unexamined.

“We don’t know for sure precisely what the constituents are that are responsible for our findings,” Dr. Marcus said. “It’s possible that there are some effects that are much more generic, such as inhaling a burned substance. There is good evidence that if you inhale pretty much any sort of particulate matter, that increases inflammation in the body. Inflammation is known to be a trigger for atrial fibrillation.”

Alternatively, all four drugs – whether stimulants or depressants – cause “quite dramatic and often rapid effects on the autonomic nervous system,” Dr. Marcus said, noting that these rapid swings are a known trigger for AFib.

Brian Olshansky, MD, emeritus professor of internal medicine-cardiovascular medicine at the University of Iowa, Iowa City, suggested that nonpharmacologic factors are likely also playing a role.

“All these drugs have slightly different mechanisms of action, so there’s not one mechanism that would explain why all of them would cause atrial fibrillation,” Dr. Olshansky said in an interview. “That does suggest that there’s something else going on, besides just the drug itself. It would be potentially concerning if we were to lay the blame totally on these drugs.”

Dr. Olshansky, who recently coauthored a review of stimulant drugs and arrhythmias, suggested that lifestyle, comorbidities, and drug impurities may have added to the risk of AF.

“[The investigators] did try to correct for that kind of stuff, but it’s very hard to correct for a lot of the issues that may be ongoing with individuals who partake in these drugs,” Dr. Olshansky said in an interview. “They may not be a healthy lot, in general.”

Still, considering previous data linking drugs of abuse with arrhythmias, he said the detected risks were “intriguing,” and deserved a closer look.

“It’s a nice groundbreaking study, with regard to the fact that they showed unique relationships that we don’t completely understand,” Dr. Olshansky said. “It opens up a new opportunity for further investigation.”

The investigators disclosed relationships with InCarda, Baylis Medical, Johnson & Johnson, and others. Dr. Olshansky disclosed no relevant competing interests.

Histopathologic analysis of the biopsy specimen revealed a dense infiltrate of large, hyperchromatic, mucin-producing cells exhibiting varying degrees of nuclear pleomorphism (Figure 1). Immunohistochemical (IHC) staining was negative for cytokeratin (CK) 20; however, CK7 was found positive (Figure 2), which confirmed the presence of a metastatic adenocarcinoma, consistent with the clinical diagnosis of a Sister Mary Joseph nodule (SMJN). Subsequent IHC workup to determine the site of origin revealed densely positive expression of both cancer antigen 125 and paired homeobox gene 8 (PAX-8)(Figure 3), consistent with primary ovarian disease. Furthermore, expression of estrogen receptor and p53 both were positive within the nuclei, illustrating an aberrant expression pattern. On the other hand, cancer antigen 19-9, caudal-type homeobox 2, gross cystic disease fluid protein 15, and mammaglobin were all determined negative, thus leading to the pathologic diagnosis of a metastatic ovarian adenocarcinoma. Additional workup with computed tomography of the abdomen and pelvis highlighted a large left ovarian mass with multiple omental nodules as well as enlarged retroperitoneal and pelvic lymph nodes.

The SMJN is a rare presentation of internal malignancy that appears as a nodule that metastasizes to the umbilicus. It may be ulcerated or necrotic and is seen in up to 10% of patients with cutaneous metastases from internal malignancy.¹ These nodules are named after Sister Mary Joseph, the surgical assistant of Dr. William Mayo who first described the relationship between umbilical nodules seen in patients with gastrointestinal and genitourinary cancer. The most common underlying malignancies include primary gastrointestinal and gynecologic adenocarcinomas. In a retrospective study of 34 patients by Chalya et al,² the stomach was found to be the most common primary site (41.1%). The presence of an SMJN affords a poor prognosis, with a mean overall survival of 11 months from the time of diagnosis.³ The mechanism of disease dissemination remains unknown but is thought to occur through lymphovascular invasion of tumor cells and spread via the umbilical ligament.^1,4

Merkel cell carcinoma is a cutaneous neuroendocrine tumor that most commonly presents in elderly patients as red-violet nodules or plaques. Although Merkel cell carcinoma most frequently is encountered on sun-exposed skin, they also can arise on the trunk and abdomen. Positive IHC staining for CK20 would be expected; however, it was negative in our case.⁵

Cutaneous endometriosis is a rare disease presentation and most commonly occurs as a secondary process due to surgical inoculation of the abdominal wall. Primary cutaneous endometriosis in which there is no history of abdominal surgery less frequently is encountered. Patients typically will report pain and cyclical bleeding with menses. Pathology demonstrates ectopic endometrial tissue with glands and uterine myxoid stroma.⁶

Amelanotic melanoma is an uncommon subtype of malignant melanoma that presents as nonpigmented nodules that have a propensity to ulcerate and bleed. Furthermore, the umbilicus is an exceedingly rare location for primary melanoma. However, one report does exist, and amelanotic melanoma should be considered in the differential for patients with umbilical nodules.⁷

Dermoid cysts are benign congenital lesions that typically present as a painless, slow-growing, and wellcircumscribed nodule, as similarly experienced by our patient. They most commonly are found on the testicles and ovaries but also are known to arise in embryologic fusion planes, and reports of umbilical lesions exist.⁸ Dermoid cysts are diagnosed based on histopathology, supporting the need for a biopsy to distinguish a malignant process from benign lesions.⁹

CHARLOTTE, N.C. – Nearly one-fourth of patients with early-onset colorectal cancer don’t get referrals for genetic counseling or testing, and although acceptance of genetic counseling has improved over the last 10 years, there is still a notable gap between referrals and uptake, investigators have found.

Among 791 patients with young- or early-onset colorectal cancer (YOCRC) seen at a large medical center from 2010 through 2019, 62.1% were referred for genetic counseling, but only 80.1% of this group followed through with the referrals by scheduling an appointment with a counselor or having genetic testing performed, reported Hareem Syed, MD, from the department of internal medicine at the Cleveland Clinic.

“Our findings highlight the need for health systems to implement care pathways to optimize genetic counseling referral and testing in all young-onset colorectal cancer patients,” she said at the annual meeting of the American College of Gastroenterology.

The incidence of CRC diagnosed in persons younger than 50 years is increasing and has been projected to double by 2030, Dr. Syed noted.

In 2009, the Eastern Cooperative Oncology Group recommended that all patients with colorectal cancer be screened for the Lynch syndrome, and earlier this year the National Comprehensive Cancer Network issued a recommendation that patients with YOCRC undergo germline multigene panel testing (MGPT). MGPT has shown that as many as 30% of patients with YOCRC carry a germline pathogenic variant that predisposes them to CRC, regardless of family history, she said.

“We hypothesized that the rate of referral to genetic counseling in this population is low despite the high incidence of pathogenic germline variants, but the uptake of genetic counseling is high [when referred],” Dr. Syed said.
 

How often, and who needs it?

The investigators sought to determine the frequency of referral to genetic counseling and patient uptake of referrals to assess factors associated with referrals and with uptake, and to evaluate the results of genetic testing.

They reviewed records on all patients younger than 50 years seen at the Cleveland Clinic for CRC from 2010 through 2019, excluding those with appendiceal cancers, a family history of a hereditary cancer syndrome, or irritable bowel syndrome.

The information they extracted from electronic medical records included patient age, sex, family history of CRC, income, tumor stage, and the location and time period of CRC diagnosis.

They considered a genetic counseling referral to be either an order for counseling in the record; clinical documentation of a referral in an office visit with colorectal surgery, oncology, or gastroenterology specialists; or documentation of a completed visit with a genetic counselor.

They considered patient uptake of a counseling referral as either a completed visit to the counselor or documentation of genetic testing results.

The mean patient age at diagnosis was 44 years, with 57.3% of patients male, and 42.7% female. The large majority of patients (86.5%) were White. In all, 40.2% of patients had a family history of CRC.

As noted above, 62.1% of the 791 patients included in the study were referred for counseling, and 80.1% of those referred followed through with uptake. Of this group, nearly all (97.1%) completed genetic testing.

In univariate analysis, factors associated with referral included older patient age at diagnosis, which showed that patients approaching 50 were less likely to receive a referral (odds ratio, 0.904), year of diagnosis with patients diagnosed in the most recent period more likely to receive a referral (OR, 1.247), and family history of CRC (OR, 2.195).

In multivariate analysis, factors significantly associated with referral were age at diagnosis (OR, 0.89), family history of CRC (OR, 2.112), and year of diagnosis (for 2017-19 vs. 2010-13, OR, 5.361).

Among 377 patients who completed genetic testing, 21% were found to have a pathogenic variant, 23% had variants of unknown significance, and 56% had no variants detected. The most commonly detected pathogenic variants were the Lynch syndrome and adenomatous polyposis.
 

Educate patients and physicians

In an interview, Daniel J. Pambianco, MD, from Charlottesville (Va.) Gastroenterology Associates, who was not involved in the study, commented that patient perceptions about the consequences of genetic testing may be a barrier to either getting a referral for counseling or following through on one.

“Oftentimes patients will perceive anything with ‘genetic’ in it as if their genes are somehow being manipulated, and we need to do a better job at educating patients in that regard,” he said.

Physicians, both primary care practitioners and gastroenterologists, also need to fully appreciate the importance of genetic testing in this population, “because in essence there may be a 4%, 5%, or 6% risk of genetic syndromes that we’re missing and cannot pick up just from getting patients’ histories,” he said.

The investigators did not report a study funding source. Dr. Syed and Dr. Pambianco reported having no relevant financial disclosures.
