Patients with ulcerative colitis who were treated with upadacitinib showed significant improvement in symptoms compared to placebo within days of starting treatment, according to results of a new study.

Immunosuppressants and biologics used to treat moderate to severe disease can vary in their response times from weeks to months, and some ambulatory patients fail to respond to these treatments, wrote Edward V. Loftus Jr., MD, of the Mayo Clinic, Rochester, Minn., and colleagues.

“The lack of effective, quick-acting therapies may lead patients to experience prolonged relapses, reduced quality of life, and a significant burden of illness,” the researchers said.

Upadacitinib, an oral, once-daily reversible JAK inhibitor, is approved by the Food and Drug Administration for patients with moderate to severe ulcerative colitis (UC) who have not responded to at least one tumor necrosis factor (TNF) blocker, but the time frame for response to upadacitinib has not been well studied, they said.

In a study published online in Clinical Gastroenterology and Hepatology, the researchers reviewed data from two phase 3 randomized, placebo-controlled induction trials, U-ACHIEVE Induction (NCT02819635) and U-ACCOMPLISH (NCT03653026), that assessed the safety and efficacy of a 45-mg daily dose of upadacitinib for managing symptoms of moderate to severe UC over an 8-week period.

The intent-to-treat analysis included 660 patients who had been randomized to received upadacitinib and 328 in the placebo group. Demographics were similar between the groups. Symptom improvement was based on changes in inflammatory markers high-sensitivity C-reactive protein (hs-CRP) and fecal calprotectin (FCP) measured at week 2. Quality of life was assessed at 2 and 8 weeks.

Between 1 and 3 days after starting treatment, significantly greater percentages of patients in the treatment arm achieved a reduction of at least 50% from baseline in hs-CRP (75.7% vs. 21.9%) and FCP (48.2% vs. 20.2%).

The significant differences in symptom improvement persisted for 14 days from the first dose.

Patients in the upadacitinib group also showed increased rates of clinical remission/response (26.9%/59.4%) based on Partial Mayo scores at week 2 compared with placebo patients (4.3%/22.3%). Treated patients showed significant improvements in quality of life at weeks 2 and 8.

In addition, patient-reported UC symptoms of stool frequency, rectal bleeding, abdominal pain, and bowel urgency improved significantly compared with placebo by day 3, the researchers noted. “In this study, upadacitinib led to absence of rectal bleeding by day 1 and absence of abdominal pain and bowel urgency by day 3 in a significant proportion of patients vs. placebo (all P < .05),” they said.

The findings were limited by the post hoc design, but reflect results of other studies, including those of the JAK inhibitor tofacitinib, the researchers noted. The results of the current study demonstrate the ability of upadacitinib to alleviate key UC symptoms as early as 1 day after the first dose, they concluded.
 

Need for rapid onset treatment

A majority of biologics used to treat IBD take weeks to months to exert an effect, “so it is crucial that a drug with more rapid onset of action become available,” Atsushi Sakuraba, MD, director of clinical trial/IBD research at the University of Chicago, said in an interview.

Dr. Sakuraba, who was not involved in the study, said he was surprised by the findings.

“It is amazing that upadacitinib started to show response in 1-3 days and showed superior rates of remission/response versus placebo by week 2,” he said.

“Clinicians treating IBD patients should take the time to response into consideration, because it leads to rapid improvement in quality of life and reduced need for steroids,” Dr. Sakuraba said. The current study findings need to be confirmed in real life studies, he cautioned.
 

Expanding clinical options

Jeffrey Berinstein, MD, of the University of Michigan, Ann Arbor, who was not involved with the study, said in an interview that he was not surprised by upadacitinib’s quick action, which supports what he has seen in clinical practice. “We now have post hoc data from the phase 3, multicenter induction trials ... to provide us with hard evidence to support our observations,” he noted.

The current study is important because many patients with UC can be very symptomatic, with rectal bleeding, diarrhea, urgency, and abdominal pain, he said in an interview.

“It is often critical to have a fast-acting medication to avoid worsening symptoms, hospitalization, and severe complications. This study shows that upadacitinib, a new oral small molecule that selectively inhibits JAK-1, works within 1 day to improve symptoms and within 2 weeks to improve CRP and fecal calprotectin,” he said.

The takeaway message to clinicians is that upadacitinib is effective, relatively safe, and fast-acting option for patients with UC who have previously failed an anti-TNF agent, he said.

Challenges remain, however.

“Despite this exciting new therapeutic, there is still significant research needed to break our current therapeutic efficacy ceiling and get more IBD patients into a stable and durable remission,” Dr. Berinstein said. “Additional research is needed to develop personalized treatment strategies to address the unique needs of individual patients and to guide optimal medical management.”

Dr. Berinstein and his team are exploring the use of upadacitinib on the sickest IBD patients, “those admitted to the hospital with acute severe ulcerative colitis,” he said. Emerging data from multiple academic centers suggest that “upadacitinib induction may be a viable treatment strategy for these very high-risk patients. Of course, large prospective trials will be needed to confirm this,” he added.

The study was funded by AbbVie, which markets upadacitinib (Rinvoq). Lead author Dr. Loftus and several study authors disclosed financial relationships with AbbVie and other companies. Dr. Sakuraba and Dr. Berinstein reported having no relevant financial conflicts.

The rate of postpartum hemorrhage for hospital deliveries in the United States increased significantly over a 20-year period, according to data from more than 76 million delivery hospitalizations from the National Inpatient Sample.

Postpartum hemorrhage remains the leading cause of maternal morbidity and mortality worldwide, and many clinical and patient-level risk factors appear to be on the rise, wrote Chiara M. Corbetta-Rastelli, MD, of the University of California, San Francisco, and colleagues.

Although practice changes have been introduced to reduce postpartum hemorrhage, recent trends in postpartum hemorrhage risk and outcomes in the context of such changes as hemorrhage safety bundles have not been examined, they said.

In a study published in Obstetrics & Gynecology, the researchers reviewed data from hospitalizations for females aged 15-54 years for deliveries between 2000 and 2019 using the National Inpatient Sample. They used a regression analysis to estimate average annual percentage changes (AAPC). Their objectives were to characterize trends and also to assess the association between risk factors and the occurrence of postpartum hemorrhage and related interventions. Demographics, clinical factors, and hospital characteristics were mainly similar between the group of patients with postpartum hemorrhage and those with no postpartum hemorrhage.

Approximately 3% (2.3 million) of 76.7 million hospitalizations for delivery were complicated by postpartum hemorrhage during the study period, and the annual rate increased from 2.7% to 4.3%.

Overall, 21.4% of individuals with delivery hospitalizations complicated by postpartum hemorrhage had one postpartum risk factor, and 1.4% had two or more risk factors. The number of individuals with at least one risk factor for postpartum hemorrhage increased significantly, from 18.6% to 26.9%, during the study period, with an annual percentage change of 1.9%.

Compared with deliveries in individuals without risk factors, individuals with one risk factor had slightly higher odds of postpartum hemorrhage (odds ratio, 1.14), but those with two or more risk factors were more than twice as likely to experience postpartum hemorrhage as those with no risk factors (OR, 2.31).

The researchers also examined the association of specific risk factors and interventions related to hemorrhage, notably blood transfusion and peripartum hysterectomy. Blood transfusions in individuals with postpartum hemorrhage increased from 5.4% to 16.7% between 2000 and 2011, (AAPC, 10.2%) then decreased from 16.7% to 12.6% from 2011 to 2019 (AAPC, –3.9%).

Peripartum hysterectomy in the study population increased from 1.4% to 2.4% from 2000 to 2009 (AAPC 5.0%), remained steady from 2009 to 2016, and then decreased from 2.1% to 0.9% from 2016 to 2019 (AAPC –27%).

Other risk factors associated with postpartum hemorrhage itself and with blood transfusion and hysterectomy in the setting of postpartum hemorrhage included prior cesarean delivery with placenta previa or accreta, placenta previa without prior cesarean delivery, and antepartum hemorrhage or placental abruption, the researchers noted.

“In addition to placental abnormalities, risk factors such as preeclampsia with severe features, polyhydramnios, and uterine leiomyomas demonstrated the highest rates of increase in our data,” they wrote in their discussion. These trends may lead to continuing increases in postpartum hemorrhage risk, which was not fully explained by the increase in risk factors seen in the current study, the researchers said.

The study findings were limited by several factors, including the use of billing codes that could lead to misclassification of diagnoses, as well as possible differences in the definition and coding for postpartum hemorrhage among hospitals, the researchers noted. Other limitations were the exclusion of cases of readmission for postpartum hemorrhage and lack of clinical details involving use of medications or nonoperative interventions, they said.

Notably, the study finding of stable to decreasing peripartum hysterectomy rates in hospitalized patients with postpartum hemorrhage conflicts with another recent study showing an increase in peripartum hysterectomy from 2009 to 2020, but this difference may reflect changes in billing, indications for hysterectomy, or study modeling, they said.

The current study was strengthened by the use of a large database to analyze population trends, a contemporary study period, and the inclusion of meaningful outcomes such as peripartum hysterectomy, the researchers wrote.

The shift in blood transfusion and peripartum hysterectomy may reflect the implementation of protocols to promote early intervention and identification of postpartum hemorrhage, they concluded.
 

Interventions can have an effect

“Hemorrhage remains a leading cause of maternal mortality in the United States and blood transfusion is the most common severe maternal morbidity,” Catherine M. Albright, MD, MS, associate professor of maternal-fetal medicine at the University of Washington, Seattle, said in an interview. “It is important to understand the current state, especially given that many hospitals have implemented policies and procedures to better identify and treat postpartum hemorrhage,” she said.

Dr. Albright said, “I was pleased to see that they did not just look at a diagnosis of postpartum hemorrhage but rather also looked at complications arising from postpartum hemorrhage, such as blood transfusion or hysterectomy.”

Postpartum hemorrhage is often a clinical diagnosis that uses estimated blood loss, a notoriously inaccurate measure, said Dr. Albright. “Additionally, the definitions of postpartum hemorrhage, as well as the ICD codes, changed during the time period of the study,” she noted. “These factors all could lead to both underreporting and overreporting of the true incidence of postpartum hemorrhage. Blood transfusion and hysterectomy are more objective outcomes and demonstrate true morbidity,” she said.

“Most of the risk factors that are listed in the article are not modifiable during that pregnancy,” said Dr. Albright. For example, a history of a prior cesarean or having a twin pregnancy is not something that can be changed, she said. “Many of the other risk factors or associated clinical factors, such as obesity, chronic hypertension, and pregestational diabetes, are modifiable, but before pregnancy. Universal and easy access to primary medical care prior to and between pregnancies may help to mitigate some of these factors,” she noted.

Looking ahead, “It would be helpful to ensure that these types of data are available at the state and hospital level; this will allow for local evaluation of programs that are in place to reduce postpartum hemorrhage risk and improve identification and treatment,” Dr. Albright said.

The study received no outside funding. Dr. Corbetta-Rastelli and Dr. Albright had no financial conflicts to disclose.

Albright, MD, MS, associate professor of maternal-fetal medicine at the University of Washington, Seattle, said in an interview. “It is important to understand the current state, especially given that many hospitals have implemented policies and procedures to better identify and treat postpartum hemorrhage,” she said.

Dr. Albright said, “I was pleased to see that they did not just look at a diagnosis of postpartum hemorrhage but rather also looked at complications arising from postpartum hemorrhage, such as blood transfusion or hysterectomy.”

Postpartum hemorrhage is often a clinical diagnosis that uses estimated blood loss, a notoriously inaccurate measure, said Dr. Albright. “Additionally, the definitions of postpartum hemorrhage, as well as the ICD codes, changed during the time period of the study,” she noted. “These factors all could lead to both underreporting and overreporting of the true incidence of postpartum hemorrhage. Blood transfusion and hysterectomy are more objective outcomes and demonstrate true morbidity,” she said.

“Most of the risk factors that are listed in the article are not modifiable during that pregnancy,” said Dr. Albright. For example, a history of a prior cesarean or having a twin pregnancy is not something that can be changed, she said. “Many of the other risk factors or associated clinical factors, such as obesity, chronic hypertension, and pregestational diabetes, are modifiable, but before pregnancy. Universal and easy access to primary medical care prior to and between pregnancies may help to mitigate some of these factors,” she noted.

Looking ahead, “It would be helpful to ensure that these types of data are available at the state and hospital level; this will allow for local evaluation of programs that are in place to reduce postpartum hemorrhage risk and improve identification and treatment,” Dr. Albright said.

The study received no outside funding. Dr. Corbetta-Rastelli and Dr. Albright had no financial conflicts to disclose.

Researchers have identified pathogenic gene variations in 12% of cases of sudden unexplained death in children.

The new study, which involved 116 cases of sudden infant death syndrome or sudden unexplained deaths in children (SUDC), suggests that available methods of chromosome testing could be used to help screen for the conditions, which together account for roughly 1,800 fatalities a year in the United States.

“Even though the Back to Sleep campaign has been incredibly effective and safe sleep practices have been promoted for years, sudden unexplained death in pediatrics remains a leading cause of death for infants and children,” said Catherine Brownstein, MPH, PhD, of Boston Children’s Hospital, lead author of the new study.

The findings suggest that chromosomal microarray analysis (CMA), the method that the researchers used in the study, “should be considered in the genetic evaluation of SUDC,” Dr. Brownstein said. The approach is the first-line method of identifying conditions such as autism spectrum disorder, developmental disabilities, multiple congenital anomalies, and epilepsy, she noted.

In the study, published in Advanced Genetics, Dr. Brownstein and her colleagues used CMA to test genes from 116 deceased infants and toddlers up to age 28 months whose deaths were classified as SIDS or SUDC (the latter term applies to children older than 1 year).

The average age at the time of death was 5.7 months; 59% of the patients were boys. In 14 of the children (12%), the CMA test identified genetic variations in the form of deletions or duplications that were pathogenic (five cases) or uncertain but “favoring pathogenicity” (nine cases). Such deletions or duplications are known as copy number variants (CNVs).

CNVs are present in most people and are not necessarily associated with disease, according to the researchers. However, certain CNVs have been linked to ASD, attention-deficit/hyperactivity disorder, schizophrenia, Crohn’s disease, epilepsy, and various congenital abnormalities.

Dr. Brownstein’s group also compared pathogenicity in the SUDC group with that of a cohort of children with ASD and with healthy control persons. They found no significant difference in pathogenicity between SUDC and autism with regard to duplications. However, children in the SUDC group were significantly more likely to have higher pathogenicity scores for deletions, compared with control persons. Some of the CMVs did not appear connected to SIDS or SUDC; two cases in boys were undiagnosed cases of Klinefelter syndrome.

The study findings were limited by several factors, including the small sample size and the inability to conduct CMA analyses on parents or obtain family history, the researchers note. Other limitations were that phenotypic data were available only from autopsy material and medical records and that the study focused on younger children, the researchers add. They did not speculate about the causes of deaths in the other cases they examined.

In the current study, the other 88% of cases could involve nongenetic factors or genetic factors that aren’t measured by next-generation sequencing or chromosomal microarray, Dr. Brownstein said. “Undiagnosed disease programs looking for genetic causes for diseases in living patients identify a cause in about 1 in 4 cases,” she said. “While 12% is a modest percentage, the CNVs identified provide additional information. In the future, the goal would be to capture the full range of potential genetic changes.”

Previous research by Dr. Brownstein’s group at Robert’s Program, a clinical service for SUDC families at Boston Children’s Hospital, found genetic variants that might cause sudden death in children.

“We began this study with the simple question of whether, as a population, these children carry more copy number variation, which they do,” she said. “However, none of the CMA findings we identified are currently associated with SUDC, so much more investigation is necessary to find out if they are coincidental, risk factors, or causative.”

Looking ahead, she said, “Ideally, we would want every family affected by sudden unexplained death in pediatrics to have genetic testing, including a chromosomal microarray. Once we have more families enrolled and tested, we will be able to understand the risk factors for SIDS and SUDC much better.”

Benjamin Solomon, MD, clinical director at the National Human Genome Research Institute, Bethesda, Md., said the new research “may bring answers for individual situations as well as enable research to understand the overall biological underpinnings and causes of disease.”

The findings “help reinforce the heterogeneous nature of SUDC and related conditions,” Dr. Solomon said. “The results also highlight some of the challenges regarding how to interpret the possible clinical effects of genetic changes. That is, every person has genetic changes, and interpreting how certain genetic changes may or may not contribute to a disease or health care outcome can be challenging.”

Research is needed to understand not only the overall causes of SUDC but also how the different causes interact, Dr. Solomon said. “Eventually, better understanding of the causes could lead to knowledge that would enable interventions that could help prevent or reduce these devastating outcomes.”

The study was supported by the Robert’s Program on Sudden Unexplained Death in Pediatrics, the Jude Zayac Foundation, multiple grants from the Eunice Kennedy Shriver National Institutes of Health/National Institute of Child Health and Human Development, the Boston Children’s Hospital Intellectual and Developmental Disabilities Research Center Molecular Genetics Core Facility (supported by the NIH/NICHD), and by the NIH National Institute of Mental Health. The researchers and Dr. Solomon have disclosed no relevant financial relationships.

The exploration started in 2004 with a 62-year-old man who presented to an emergency department with acute shortness of breath, tachycardia with chest discomfort, and light-headedness, Amado Alejandro Baez, MD, said in a presentation at the 2022 scientific assembly of the American College of Emergency Physicians.

The patient arrived on day 20 after a radical cystoprostatectomy. He had driven 4 hours from another city for a urology follow-up visit. On arrival, he developed respiratory distress symptoms and presented to the emergency department, said Dr. Baez, professor of emergency medicine and epidemiology at the Medical College of Georgia/Augusta University and triple-board certified in EMS, emergency medicine, and critical care.

The patient developed a massive pulmonary embolism with acute cor pulmonale (right-sided heart failure). An electrocardiogram showed an S1Q3T3, demonstrating the distinctive nature of right ventricular failure, said Dr. Baez.

Research has demonstrated the differences in physiology between the right and left ventricles, he said.

Dr. Baez highlighted some of the features of right ventricle (RV) failure and how to manage it. Notably, the RV is thinner and less resilient. “RV failure patients may fall off the Starling curve,” in contrast to patients with isolated left ventricle (LV) failure.

RV pressure overload is associated with a range of conditions, such as pericardial disease, pulmonary embolism, acute respiratory distress syndrome, and pulmonary arterial hypertension. When combined with RV overload, patients may develop intracardiac shunting or coronary heart disease, Dr. Baez said. Decreased contractility associated with RV failure can result from sepsis, right ventricular myocardial infarction, myocarditis, and arrhythmia.

Dr. Baez cited the 2018 scientific statement from the American Heart Association on the evaluation and management of right-sided heart failure. The authors of the statement noted that the complicated geometry of the right heart makes functional assessment a challenge. They wrote that various hemodynamic and biochemical markers can help guide clinical assessment and therapeutic decision-making.

Increased RV afterload drives multiple factors that can ultimately lead to cardiogenic shock and death, said Dr. Baez. These factors include decreased RV oxygen delivery, decreased RV coronary perfusion, decreased systemic blood pressure, and low carbon monoxide levels. RV afterload also leads to decreased RV contractility, an increase in RV oxygen demand, and tension in the RV wall, and it may contribute to tricuspid valve insufficiency, neurohormonal activation, and RV ischemia.

Treatment strategies involve improving symptoms and stopping disease progression, said Baez. In its scientific statement, the AHA recommends steps for assessing RV and LV function so as to identify RV failure as soon as possible, he said. After excluding pericardial disease, the AHA advises diagnosis and treatment of etiology-specific causes, such as right ventricular MI, pulmonary embolism, and sepsis. For arrhythmias, it recommends maintaining sinus rhythm when possible and considering a pacemaker to maintain atrioventricular synchrony and to avoid excessive bradycardia.

In its statement, the AHA also recommends optimizing preload with right arterial pressure/central venous pressure of 8-12 mm Hg, said Dr. Baez. Preload optimization combined with afterload reduction and improved contractility are hallmarks of care for patients with RV failure.

Avoiding systemic hypotension can prevent sequelae, such as myocardial ischemia and further hypotension, he said.

Optimization of fluid status is another key to managing RV failure, said Dr. Baez. Right heart coronary perfusion pressure can be protected by maintaining mean arterial pressure, and consideration should be given to reducing the RV afterload. Other strategies include inotropic medications and rhythm stabilization.

In general, for RV failure patients, “correct hypoxia, hypercarbia, and acidosis and avoid intubation when possible,” he said. Extracorporeal membrane oxygenation (ECMO) may be an option, depending on how many mechanical ventilator settings need to be adjusted.

In a study by Dr. Baez and colleagues published in Critical Care Medicine, the authors presented a Bayesian probability model for plasma lactate and severity of illness in cases of acute pulmonary embolism. “This Bayesian model demonstrated that the combination of shock index and lactate yield superior diagnostic gains than those compare to the sPESI and lactate,” Dr. Baez said.

The care model needs to be specific to the etiology, he added. Volume management in congested pulmonary hypertension involves a “squeeze and diurese” strategy.

According to the Internet Book of Critical Care, for patients with mean arterial pressure (MAP) of 60 mm Hg, central venous pressure (CVP) of 25 mm Hg, renal perfusion pressure of 25 mm Hg, and no urine output, a vasopressor should be added to treatment, Dr. Baez said. In cases in which the MAP 75 mm Hg, the CVP is 25 mm Hg, the renal perfusion pressure is 50 mm Hg, and the patient has good urine output, vasopressors should be continued and fluid should be removed through use of a diuretic. For patients with a MAP of 75 mm Hg, a CVP of 12 mm Hg, and renal perfusion pressure of 63 mm Hg who have good urine output, the diuretic and the vasopressor should be discontinued.

Dr. Baez also reviewed several clinical studies of the utility of acute mechanical circulatory support systems for RV failure.

In two small studies involving a heart pump and a right ventricular assistive device, the 30-day survival rate was approximately 72%-73%. A study of 179 patients involving ECMO showed an in-hospital mortality rate of 38.6%, he said.

Overall, “prompt diagnosis, hemodynamic support, and initiation of specific treatment” are the foundations of managing RV failure, he concluded.

Dr. Baez disclosed no relevant financial relationships.

LAS VEGAS – Effective management of alopecia areata starts with confirmation of the correct diagnosis and assessment of disease severity, Brett King, MD, said in a presentation at MedscapeLive’s annual Las Vegas Dermatology Seminar.

“Some patients don’t have alopecia, but they have been managed for it,” he said. “Whenever there is an ounce of doubt, take a biopsy,” he advised.

Assessing disease severity in patients with alopecia areata (AA) is especially important as new therapies become available, said Dr. King, associate professor of dermatology at Yale University, New Haven, Conn. The Severity of Alopecia Tool (SALT) Score has been available since 2004, and remains a useful tool to estimate percent hair loss. The SALT Score divides the scalp into four sections: 18% each for the right and left sides, 40% for the top of the head, and 24% for the back of the head, said Dr. King. However, the SALT Score can be enhanced or modified based on a holistic approach to disease severity that categorizes alopecia as mild (scalp hair loss of 20% or less), moderate (scalp hair loss of 21 to 49%), or severe (scalp hair loss of 50% or more).

For example, if a patient’s hair loss based on SALT Score is mild or moderate, increase the severity by 1 level (from mild to moderate, or moderate to severe) if any of the following conditions apply: Noticeable eyebrow or eyelash involvement, inadequate treatment response after 6 months, diffuse positive hair pull test consistent with rapid progression of AA, or a negative impact on psychosocial functioning because of AA, he said.
 

Treatment advances

Understanding of the pathogenesis of AA has been slow to evolve, Dr. King noted. “We haven’t been able to shake this concept that people are causing the disease by being depressed,” as noted in the literature from the 1950s.

In 2014, breakthrough research changed the game by identifying the roles of interferon gamma and interleukin 15, Dr. King said. Since then, more research has been conducted on Janus kinase (JAK) inhibitors for AA. Dr. King was a coinvestigator on a 2014 case report in which a patient with psoriasis and alopecia universalis experienced regrowth of most of his body hair after 8 months of daily oral tofacitinib, a JAK inhibitor.

However, despite the dramatic results in some patients, “tofacitinib doesn’t always work,” said Dr. King. In his experience, patients for whom tofacitinib didn’t work were those with complete or nearly complete scalp hair loss for more than 10 years.

Approval of baricitinib

Dr. King’s recent work supported the approval in June 2022 of oral baricitinib, a JAK inhibitor, for AA. He reviewed data from his late-breaker abstract presented at the annual meeting of the American Academy of Dermatology in March 2022, where he reported that almost 40% of adults with AA treated with 4 mg of baricitinib daily had significant hair regrowth over 52 weeks.

Two other oral JAK inhibitors in the pipeline for AA are deuruxolitinib and ritlecitinib, which significantly increased the proportion of patients achieving SALT scores of 20 or less, compared with patients on placebo in early clinical trials. Data on both were presented at the annual meeting of the European Academy of Dermatology and Venereology.

So far, topical JAK inhibitors have not shown success in hair regrowth for AA patients, said Dr. King. Phase 2 studies of both ruxolitinib 1.5% cream and delgocitinib ointment were ineffective for AA.
 

Emerging role for oral minoxidil

Oral minoxidil has had a recent resurgence as an adjunct therapy to the new JAK inhibitors. A study published in 1987 found that, with oral minoxidil monotherapy, a cosmetic response was seen in 18% of patients with AA, Dr. King said.

In a study published in the Journal of the American Academy of Dermatology, Dr. King and colleagues noted that dose escalation is sometimes needed for effective treatment of AA with tofacitinib. They examined the effect of adding oral minoxidil to tofacitinib in patients with severe AA as a way to increase efficacy without increasing tofacitinib dosage. They reviewed data from 12 patients ages 18-51 years who were prescribed 5 mg of tofacitinib twice daily, plus 2.5 mg oral minoxidil daily for women and 2.5 mg of minoxidil twice daily for men; women received a lower dose to minimize the side effect of hypertrichosis.

After 6 months, 67% (eight patients) achieved at least 75% hair regrowth; of those eight patients, seven (58% of the total) had hair regrowth on a twice-daily dose of 5 mg tofacitinib with no need for dose escalation, Dr. King said.

More research is needed, but oral minoxidil may be a useful adjunct treatment for some patients with AA, he added.

During a question and answer session, Dr. King was asked to elaborate on the mechanism of minoxidil in combination with JAK inhibitors. “The truth is that I just don’t know” why the combination works for some patients. However, the majority of patients who succeed with this combination regrow hair by 4 months. “There is something special about that combination.”

LAS VEGAS – Effective management of alopecia areata starts with confirmation of the correct diagnosis and assessment of disease severity, Brett King, MD, said in a presentation at MedscapeLive’s annual Las Vegas Dermatology Seminar.

“Some patients don’t have alopecia, but they have been managed for it,” he said. “Whenever there is an ounce of doubt, take a biopsy,” he advised.

Being male, being older, and having a clear intent to die were among the key independent predictors of psychiatric hospital admission after self-harm, based on data from more than 1,800 individuals.

Clinicians who assess suicidal patients in the emergency department setting face the challenge of whether to admit the patient to inpatient or outpatient care, and data on predictors of compulsory admission are limited, wrote Laurent Michaud, MD, of the University of Lausanne, Switzerland, and colleagues.

To better identify predictors of hospitalization after self-harm, the researchers reviewed data from 1,832 patients aged 18 years and older admitted to four emergency departments in Switzerland between December 2016 and November 2019 .

Self-harm (SH) was defined in this study as “all nonfatal intentional acts of self-poisoning or self-injury, irrespective of degree of suicidal intent or other types of motivation,” the researchers noted. The study included 2,142 episodes of self-harm.

The researchers conducted two analyses. They compared episodes followed by any hospitalization and those with outpatient follow-up (1,083 episodes vs. 1,059 episodes) and episodes followed by compulsory hospitalization (357 episodes) with all other episodes followed by either outpatient care or voluntary hospitalization (1,785 episodes).

Overall, women were significantly more likely to be referred to outpatient follow-up compared with men (61.8% vs. 38.1%), and hospitalized patients were significantly older than outpatients (mean age of 41 years vs. 36 years, P < .001 for both).

“Not surprisingly, major psychopathological conditions such as depression, mania, dementia, and schizophrenia were predictive of hospitalization,” the researchers noted.

Other sociodemographic factors associated with hospitalization included living alone, no children, problematic socioeconomic status, and unemployment. Clinical factors associated with hospitalization included physical pain, more lethal suicide attempt method, and clear intent to die.

In a multivariate analysis, independent predictors of any hospitalization included male gender, older age, assessment in the Neuchatel location vs. Lausanne, depression vs. personality disorders, substance use, or anxiety disorder, difficult socioeconomic status, a clear vs. unclear intent to die, and a serious suicide attempt vs. less serious.

Differences in hospitalization based on hospital setting was a striking finding, the researchers wrote in their discussion. These differences may be largely explained by the organization of local mental health services and specific institutional cultures; the workload of staff and availability of beds also may have played a role in decisions to hospitalize, they said.

The findings were limited by several factors including the lack of data on the realization level of a self-harm episode and significant events such as a breakup, the researchers explained. Other limitations included missing data, multiple analyses that could increase the risk of false positives, the reliance on clinical diagnosis rather than formal instruments, and the cross-sectional study design, they said.

However, the results have clinical implications, as the clinical factors identified could be used to target subgroups of suicidal populations and refine treatment strategies, they concluded.

The study was supported by institutional funding and the Swiss Federal Office of Public Health. The researchers had no financial conflicts to disclose.

LAS VEGAS – The delay in the diagnosis of hidradenitis suppurativa (HS) often ranges from 7 to 10 years, which results in increased morbidity and disease severity, and an extended impact on quality of life, Robert G. Micheletti, MD, said in a presentation at MedscapeLive’s annual Las Vegas Dermatology Seminar.

For patients with HS, “the quality-of-life impact is profound, greater than any other systematically studied dermatologic condition,” said Dr. Micheletti, associate professor of dermatology at the Hospital of the University of Pennsylavnia, and chief of hospital dermatology, and chief of dermatology at Pennsylvania Hospital, Philadelphia.

Two key aspects of quality of life that affect HS patients are sexual health and overall pain, he said. The female-to-male ratio of HS is approximately 3:1, and data show that approximately 40% of female HS patients experience fertility issues and have unaddressed questions about HS and pregnancy, said Dr. Micheletti. Additionally, data from a systematic review showed that 50%-60% of patients with HS reported sexual dysfunction. Impaired sexual function is also associated with both overall impaired quality of life ratings and the presence of mood disorders, he noted.

Pain also has a significant impact on quality of life for HS patients. When these patients present in an emergency department, 70% report severe pain, and approximately 60% receive opioids, said Dr. Micheletti.

Data from a 2021 study showed that HS patients are significantly more likely to receive opioids compared with controls, and also more likely to be diagnosed with opioid use disorder than controls, especially if they are seen by nondermatologists, he noted.

For acute pain, Dr. Micheletti recommended starting with acetaminophen 500 mg every 4 to 6 hours as needed, and topical nonsteroidal anti-inflammatory drugs (NSAIDs). “It still makes sense to do topical care,” said Dr. Micheletti, but he added that he also prescribes medications for anxiety for these patients.

Patients with increased pain severity or refractory disease may benefit from systemic NSAIDs, or intralesional triamcinolone, he noted. Incision and draining of abscesses may provide temporary symptomatic relief, but keep in mind that lesions will recur, he noted.

For the most severe cases, Dr. Micheletti advised adding tramadol as a first-line opioid, or another short-acting opioid for breakthrough pain.

To manage patients with HS who have chronic pain, Dr. Micheletti recommended starting with HS disease–directed therapy, but also screening for pain severity and psychological comorbidities.

His strategies in these cases include nonpharmacological pain management in the form of physical therapy, wound care, and behavioral health. His algorithm for nociceptive pain is NSAIDs with or without acetaminophen; duloxetine or nortriptyline are other options. For neuropathic pain, gabapentin and/or duloxetine are top choices, but pregabalin, venlafaxine, and nortriptyline are on the list as well.

Topical NSAIDs or topical lidocaine may serve as add-ons to systemic therapy in more severe cases, or as first-line therapy for milder chronic pain, Dr. Micheletti noted. Patients who have failed treatment with at least two pharmacologic agents, suffer medically refractory HS with debilitating pain, or use opioids on an ongoing basis should be referred to a pain management specialist, he said.
 

Don’t forget lifestyle

Although data on the impact of diet on patients with HS are limited, “we know anecdotally that dairy and refined carbohydrates are associated with exacerbations,” said Dr. Micheletti.

In addition, many patients use complementary medicine “and they aren’t always telling us,” he emphasized. Smoking is prevalent among patients with HS, and is a risk factor for the disease in general, and for more severe and refractory disease, he added. Consequently, screening for tobacco smoking is recommended for patients with HS not only because of the impact on disease, but because it is a potentially modifiable cardiovascular risk factor, he explained.
 

Consider comorbidities

Cardiovascular disease is among several comorbidities associated with HS, said Dr. Micheletti. HS foundations in the United States and Canada recently published evidence-based recommendations for comorbidity screening. The recommendations included screening for 19 specific comorbidities: acne, dissecting cellulitis, pilonidal disease, pyoderma gangrenosum, depression, anxiety, suicide, smoking, substance abuse, polycystic ovary syndrome, obesity, dyslipidemia, diabetes mellitus, metabolic syndrome, hypertension, cardiovascular disease, inflammatory bowel disease, spondyloarthritis, and sexual dysfunction.

Dr. Micheletti highlighted cardiovascular comorbidities, and noted the association between HS and modifiable cardiovascular risk factors: smoking, obesity, diabetes mellitus, and dyslipidemia. “HS is also independently associated with cardiovascular disease leading to myocardial infarction, stroke, cardiovascular-associated death, and all-cause mortality compared to controls,” he said. Studies show an incidence rate ratio of 1.53 for major adverse cardiovascular events in patients with HS compared with controls, with the highest relative risk among those aged 18-29 years, he added.
 

Medical management

Depending on the patient, medical management of HS may involve antibiotics, hormonal agents, and biologics, said Dr. Micheletti. Some of the most commonly used antibiotic regimens for HS are those recommended in treatment guidelines, including doxycycline and a clindamycin/rifampin combination, he said. However, the use of trimethoprim-sulfamethoxazole or ciprofloxacin has been associated with increased antibiotic resistance and is not supported by available evidence, he noted.

Hormonal therapies may help some women with HS, said Dr. Micheletti. Options include spironolactone, metformin, or estrogen-containing hormonal contraceptives, he said.

When it comes to biologics, only 33% of HS patients meet criteria for their use (Hurley stage II or III, moderate or severe HS), he noted. However, research suggests “a huge gap” in the use of anti-TNF therapy even among patients for whom it is recommended, he said.

Of the TNF-alpha inhibitors, data on adalimumab, which is FDA-approved for HS, are the most recent. Adalimumab “is our gold standard biologic and our gateway biologic, for HS at this time,” Dr. Micheletti said.

However, those who respond to adalimumab “can continue to do better, but they can wax and wane and flare,” he cautioned. Infliximab, while not approved for HS, has been studied in patients with HS and is prescribed by some providers. Although no comparative studies have been done for infliximab versus adalimumab, “anecdotally, response to infliximab tends to be better, and it is the most effective biologic in common use for severe HS,” he noted.

Dr. Micheletti’s top treatment recommendations for using biologics start with considering biosimilars. Most patients on biosimilars do fine, but some patients who previously responded to infliximab will unpredictably lose efficacy or have reactions when switched to a biosimilar, he said.

Patients on biologics also may experience waning efficacy in the wake of an immune response stimulated by foreign antibodies, said Dr. Micheletti. “Anti-drug antibody formation is more likely to occur when treatment is interrupted,” he noted. Minimize the risk of antibody formation by paying attention to adherence issues and dosing frequency, he advised.

If patients fail both adalimumab and infliximab, Dr. Micheletti tells them not to lose hope, and that treatment is a trial-and-error process that may involve more than one therapy. Other biologics in active use for HS include ustekinumab, anakinra, secukinumab, brodalumab, golimumab, and JAK inhibitors, any of which might be effective in any given patient, he said.
 

Surgical solutions

For HS patients with chronic, recurring inflammation and drainage associated with a sinus tract, surgical deroofing may the best treatment option, Dr. Micheletti said. “Deroofing involves the use of a probe to trace the extent of the subcutaneous tract, followed by incision and removal of the tract ‘roof,’ ’’ he explained. The deroofing procedure involves local anesthesia and has a low morbidity rate, as well as a low recurrence rate and high levels of patient satisfaction, he said.

“The acute role for surgery is to remove active foci of inflammation and relieve pain,” which is achieved more effectively with deroofing, said Dr. Micheletti. By contrast, incision and drainage is associated with an almost 100% recurrence rate, he added.

When planning elective surgery for HS, Dr. Micheletti noted that holding infliximab for less than 4 weeks does not affect postoperative infection rates in patients with rheumatoid arthritis, and a recent randomized, controlled trial showed that adalimumab can be continued safely through HS surgeries.

In fact, “continuing TNF inhibitors through elective surgery does not increase infection risk and results in better disease control,” and dermatologists should work with surgery to balance infection and disease flare concerns in HS patients, he said.

LAS VEGAS – The delay in the diagnosis of hidradenitis suppurativa (HS) often ranges from 7 to 10 years, which results in increased morbidity and disease severity, and an extended impact on quality of life, Robert G. Micheletti, MD, said in a presentation at MedscapeLive’s annual Las Vegas Dermatology Seminar.

For patients with HS, “the quality-of-life impact is profound, greater than any other systematically studied dermatologic condition,” said Dr. Micheletti, associate professor of dermatology at the Hospital of the University of Pennsylavnia, and chief of hospital dermatology, and chief of dermatology at Pennsylvania Hospital, Philadelphia.

Two key aspects of quality of life that affect HS patients are sexual health and overall pain, he said. The female-to-male ratio of HS is approximately 3:1, and data show that approximately 40% of female HS patients experience fertility issues and have unaddressed questions about HS and pregnancy, said Dr. Micheletti. Additionally, data from a systematic review showed that 50%-60% of patients with HS reported sexual dysfunction. Impaired sexual function is also associated with both overall impaired quality of life ratings and the presence of mood disorders, he noted.

Pain also has a significant impact on quality of life for HS patients. When these patients present in an emergency department, 70% report severe pain, and approximately 60% receive opioids, said Dr. Micheletti.

Data from a 2021 study showed that HS patients are significantly more likely to receive opioids compared with controls, and also more likely to be diagnosed with opioid use disorder than controls, especially if they are seen by nondermatologists, he noted.

For acute pain, Dr. Micheletti recommended starting with acetaminophen 500 mg every 4 to 6 hours as needed, and topical nonsteroidal anti-inflammatory drugs (NSAIDs). “It still makes sense to do topical care,” said Dr. Micheletti, but he added that he also prescribes medications for anxiety for these patients.

Patients with increased pain severity or refractory disease may benefit from systemic NSAIDs, or intralesional triamcinolone, he noted. Incision and draining of abscesses may provide temporary symptomatic relief, but keep in mind that lesions will recur, he noted.

For the most severe cases, Dr. Micheletti advised adding tramadol as a first-line opioid, or another short-acting opioid for breakthrough pain.

To manage patients with HS who have chronic pain, Dr. Micheletti recommended starting with HS disease–directed therapy, but also screening for pain severity and psychological comorbidities.

His strategies in these cases include nonpharmacological pain management in the form of physical therapy, wound care, and behavioral health. His algorithm for nociceptive pain is NSAIDs with or without acetaminophen; duloxetine or nortriptyline are other options. For neuropathic pain, gabapentin and/or duloxetine are top choices, but pregabalin, venlafaxine, and nortriptyline are on the list as well.

Topical NSAIDs or topical lidocaine may serve as add-ons to systemic therapy in more severe cases, or as first-line therapy for milder chronic pain, Dr. Micheletti noted. Patients who have failed treatment with at least two pharmacologic agents, suffer medically refractory HS with debilitating pain, or use opioids on an ongoing basis should be referred to a pain management specialist, he said.
 

Don’t forget lifestyle

Although data on the impact of diet on patients with HS are limited, “we know anecdotally that dairy and refined carbohydrates are associated with exacerbations,” said Dr. Micheletti.

In addition, many patients use complementary medicine “and they aren’t always telling us,” he emphasized. Smoking is prevalent among patients with HS, and is a risk factor for the disease in general, and for more severe and refractory disease, he added. Consequently, screening for tobacco smoking is recommended for patients with HS not only because of the impact on disease, but because it is a potentially modifiable cardiovascular risk factor, he explained.
 

Consider comorbidities

Cardiovascular disease is among several comorbidities associated with HS, said Dr. Micheletti. HS foundations in the United States and Canada recently published evidence-based recommendations for comorbidity screening. The recommendations included screening for 19 specific comorbidities: acne, dissecting cellulitis, pilonidal disease, pyoderma gangrenosum, depression, anxiety, suicide, smoking, substance abuse, polycystic ovary syndrome, obesity, dyslipidemia, diabetes mellitus, metabolic syndrome, hypertension, cardiovascular disease, inflammatory bowel disease, spondyloarthritis, and sexual dysfunction.

Dr. Micheletti highlighted cardiovascular comorbidities, and noted the association between HS and modifiable cardiovascular risk factors: smoking, obesity, diabetes mellitus, and dyslipidemia. “HS is also independently associated with cardiovascular disease leading to myocardial infarction, stroke, cardiovascular-associated death, and all-cause mortality compared to controls,” he said. Studies show an incidence rate ratio of 1.53 for major adverse cardiovascular events in patients with HS compared with controls, with the highest relative risk among those aged 18-29 years, he added.
 

Medical management

Depending on the patient, medical management of HS may involve antibiotics, hormonal agents, and biologics, said Dr. Micheletti. Some of the most commonly used antibiotic regimens for HS are those recommended in treatment guidelines, including doxycycline and a clindamycin/rifampin combination, he said. However, the use of trimethoprim-sulfamethoxazole or ciprofloxacin has been associated with increased antibiotic resistance and is not supported by available evidence, he noted.

Hormonal therapies may help some women with HS, said Dr. Micheletti. Options include spironolactone, metformin, or estrogen-containing hormonal contraceptives, he said.

When it comes to biologics, only 33% of HS patients meet criteria for their use (Hurley stage II or III, moderate or severe HS), he noted. However, research suggests “a huge gap” in the use of anti-TNF therapy even among patients for whom it is recommended, he said.

Of the TNF-alpha inhibitors, data on adalimumab, which is FDA-approved for HS, are the most recent. Adalimumab “is our gold standard biologic and our gateway biologic, for HS at this time,” Dr. Micheletti said.

However, those who respond to adalimumab “can continue to do better, but they can wax and wane and flare,” he cautioned. Infliximab, while not approved for HS, has been studied in patients with HS and is prescribed by some providers. Although no comparative studies have been done for infliximab versus adalimumab, “anecdotally, response to infliximab tends to be better, and it is the most effective biologic in common use for severe HS,” he noted.

Dr. Micheletti’s top treatment recommendations for using biologics start with considering biosimilars. Most patients on biosimilars do fine, but some patients who previously responded to infliximab will unpredictably lose efficacy or have reactions when switched to a biosimilar, he said.

Patients on biologics also may experience waning efficacy in the wake of an immune response stimulated by foreign antibodies, said Dr. Micheletti. “Anti-drug antibody formation is more likely to occur when treatment is interrupted,” he noted. Minimize the risk of antibody formation by paying attention to adherence issues and dosing frequency, he advised.

If patients fail both adalimumab and infliximab, Dr. Micheletti tells them not to lose hope, and that treatment is a trial-and-error process that may involve more than one therapy. Other biologics in active use for HS include ustekinumab, anakinra, secukinumab, brodalumab, golimumab, and JAK inhibitors, any of which might be effective in any given patient, he said.
 

Surgical solutions

For HS patients with chronic, recurring inflammation and drainage associated with a sinus tract, surgical deroofing may the best treatment option, Dr. Micheletti said. “Deroofing involves the use of a probe to trace the extent of the subcutaneous tract, followed by incision and removal of the tract ‘roof,’ ’’ he explained. The deroofing procedure involves local anesthesia and has a low morbidity rate, as well as a low recurrence rate and high levels of patient satisfaction, he said.

“The acute role for surgery is to remove active foci of inflammation and relieve pain,” which is achieved more effectively with deroofing, said Dr. Micheletti. By contrast, incision and drainage is associated with an almost 100% recurrence rate, he added.

When planning elective surgery for HS, Dr. Micheletti noted that holding infliximab for less than 4 weeks does not affect postoperative infection rates in patients with rheumatoid arthritis, and a recent randomized, controlled trial showed that adalimumab can be continued safely through HS surgeries.

In fact, “continuing TNF inhibitors through elective surgery does not increase infection risk and results in better disease control,” and dermatologists should work with surgery to balance infection and disease flare concerns in HS patients, he said.

COVID-19 vaccines retained the ability to prevent deaths from COVID-19 in children and adolescents regardless of the dominant circulating variant, in a new study.

The vaccine’s effectiveness against infection in the short term has been established, as has the waning effectiveness of the vaccine over time, wrote Juan Manuel Castelli, MD, of the Ministry of Health of Argentina, Buenos Aires, and colleagues, in the British Medical Journal.

However, data on the impact of vaccine effectiveness on mortality in children and adolescents are limited, especially during periods of omicron variant dominance, the researchers said.

In their new study, the researchers reviewed data from 844,460 children and adolescents aged 3-17 years from the National Surveillance System and the Nominalized Federal Vaccination Registry of Argentina, during a time that included a period of omicron dominance.

Argentina began vaccinating adolescents aged 12-17 years against COVID-19 in August 2021 and added children aged 3-11 years in October 2021. Those aged 12-17 years who were considered fully vaccinated received two doses of either Pfizer-BioNTech and/or Moderna vaccines, and fully-vaccinated 3- to 11-year-olds received two doses of Sinopharm vaccine.

The average time from the second vaccine dose to a COVID-19 test was 66 days for those aged 12-17 years and 54 days for 3- to 11-year-olds. The researchers matched COVID-19 cases with uninfected controls, and a total of 139,321 cases were included in the analysis.

Overall, the estimated vaccine effectiveness against COVID-19 was 64.2% during a period of delta dominance (61.2% in children aged 3-11 years and 66.8% in adolescents aged 12-17 years).

During a period of omicron dominance, estimated vaccine effectiveness was 19.9% across all ages (15.9% and 26.0% for younger and older age groups, respectively).

Effectiveness of the vaccine decreased over time, regardless of the dominant variant, but the decline was greater during the omicron dominant period, the researchers noted. During the omicron period, effectiveness in children aged 3-11 years decreased from 37.6% at 15-30 days postvaccination to 2.0% at 60 days or longer after vaccination. In adolescents aged 12-17 years, vaccine effectiveness during the omicron period decreased from 55.8% at 15-30 days postvaccination to 12.4% at 60 days or longer after vaccination.

Despite the waning protection against infection, the vaccine’s effectiveness against death from COVID-19 was 66.9% in children aged 3-11 years and 97.6% in adolescents aged 12-17 during the period of omicron dominance, the researchers noted.

The results are consistent with similar studies showing a decreased vaccine effectiveness against infection but a persistent effectiveness against deaths over time, the researchers wrote in the discussion section of their paper.

“Our results suggest that the primary vaccination schedule is effective in preventing mortality in children and adolescents with COVID-19 regardless of the circulating SARS-CoV-2 variant,” the researchers said.
 

Study limitations and strengths

The study was limited by several factors including the incomplete data on symptoms and hospital admissions, the possible impact of unmeasured confounding variables, and the observational design that prevents conclusions of causality, the researchers noted. However, the results were strengthened by the large sample size and access to detailed vaccination records, they said.

Both heterologous and homologous mRNA vaccine schedules showed similar effectiveness in preventing short-term infection and mortality from COVID-19 during periods of differing dominant variants, they noted.

The study findings support the vaccination of children against COVID-19 as an important public health measure to prevent mortality in children and adolescents, they concluded.
 

Data support value of vaccination, outside experts say

“COVID vaccines may not be as effective over time as the gene variants in the SARS-CoV-2 virus change,” Adrienne G. Randolph, MD, a pediatrician at Harvard Medical School and Boston Children’s Hospital, said in an interview. “Therefore, it is essential to assess vaccine effectiveness over time to look at effectiveness against variants and duration of effectiveness.” Dr. Randolph, who was not involved in the study, said she was not surprised by the findings, which she described as consistent with data from the United States. “COVID vaccines are very effective against preventing life-threatening disease, but the effectiveness against less severe illness for COVID vaccines is not as effective against Omicron,” she noted. 

The take-home message for clinicians is that it’s important to get children vaccinated against COVID to prevent severe and life-threatening illness, said Dr. Randolph. “Although these cases are uncommon in children, it is not possible to predict which children will be the most severely affected by COVID,” she emphasized.

However, “we need more data on the new COVID booster vaccines in children that are designed to be more effective against Omicron’s newer variants,” Dr. Randolph said in an interview. “We also need more data on COVID vaccine effectiveness in the youngest children, under 5 years of age, and data on vaccinating mothers to prevent COVID in infants,” she said.

Tim Joos, MD, a Seattle-based clinician who practices a combination of internal medicine and pediatrics, agreed that future research should continue to assess how the new COVID boosters are faring against new variants, noting that the current study did not include data from children who received the new bivalent vaccine.

“The methodology of this study uses a test negative case control design which is common for estimating vaccine effectiveness post-release of a vaccine, but is subject to biases,” Dr. Joos explained. “These are not the clean effectiveness numbers of the prospective randomized control trials that we are used to hearing about when a vaccine is first being approved.”

“Nevertheless, the study reinforces the initial manufacturers’ studies that the vaccines are effective at preventing infection in the pediatric population,” Dr. Joos said in an interview. The current study also reinforces the effectiveness of vaccines in preventing “the rare but devastating mortality from COVID-19 in the pediatric population.”

Commenting on other research showing an increasing ratio of COVID deaths among vaccinated individuals compared to total COVID deaths, he noted that this finding is “likely reflecting a denominator effect of rapidly declining COVID deaths overall,” partly from the vaccines and partly from immunity after previous natural infection.

The study received no outside funding. The researchers, Dr. Randolph, and Dr. Joos had no financial conflicts to disclose. Dr. Joos serves on the Editorial Advisory Board of Pediatric News.

Randolph, MD, a pediatrician at Harvard Medical School and Boston Children’s Hospital, said in an interview. “Therefore, it is essential to assess vaccine effectiveness over time to look at effectiveness against variants and duration of effectiveness.” Dr. Randolph, who was not involved in the study, said she was not surprised by the findings, which she described as consistent with data from the United States. “COVID vaccines are very effective against preventing life-threatening disease, but the effectiveness against less severe illness for COVID vaccines is not as effective against Omicron,” she noted. 

The take-home message for clinicians is that it’s important to get children vaccinated against COVID to prevent severe and life-threatening illness, said Dr. Randolph. “Although these cases are uncommon in children, it is not possible to predict which children will be the most severely affected by COVID,” she emphasized.

However, “we need more data on the new COVID booster vaccines in children that are designed to be more effective against Omicron’s newer variants,” Dr. Randolph said in an interview. “We also need more data on COVID vaccine effectiveness in the youngest children, under 5 years of age, and data on vaccinating mothers to prevent COVID in infants,” she said.

Tim Joos, MD, a Seattle-based clinician who practices a combination of internal medicine and pediatrics, agreed that future research should continue to assess how the new COVID boosters are faring against new variants, noting that the current study did not include data from children who received the new bivalent vaccine.

“The methodology of this study uses a test negative case control design which is common for estimating vaccine effectiveness post-release of a vaccine, but is subject to biases,” Dr. Joos explained. “These are not the clean effectiveness numbers of the prospective randomized control trials that we are used to hearing about when a vaccine is first being approved.”

“Nevertheless, the study reinforces the initial manufacturers’ studies that the vaccines are effective at preventing infection in the pediatric population,” Dr. Joos said in an interview. The current study also reinforces the effectiveness of vaccines in preventing “the rare but devastating mortality from COVID-19 in the pediatric population.”

Commenting on other research showing an increasing ratio of COVID deaths among vaccinated individuals compared to total COVID deaths, he noted that this finding is “likely reflecting a denominator effect of rapidly declining COVID deaths overall,” partly from the vaccines and partly from immunity after previous natural infection.

The study received no outside funding. The researchers, Dr. Randolph, and Dr. Joos had no financial conflicts to disclose. Dr. Joos serves on the Editorial Advisory Board of Pediatric News.

The uptake and treatment costs of biosimilar drugs in the United States from 2011 to 2020 were significantly higher than in both Germany and Switzerland, based on data from a cohort study of publicly available commercial databases.

Biologics remain the fastest growing segment of drug research and development, but their costs remain high, David L. Carl, MSc, of the University of Zurich, and colleagues wrote in their study, published online in JAMA Network Open.

As patents and regulatory exclusivity periods expire, biologics face competition from biosimilars, which may drive competition and lower prices, they said.

“However, studies have shown that there are varying policies and biosimilar uptake in European countries and that the observed levels of competition and uptake have not reached the expected levels in the U.S.,” the researchers said.

To assist the discussions of policy makers in the United States and Europe as they consider legislative and regulatory reforms that are intended to promote the competition of biosimilars, the researchers reviewed data from 15 biosimilars and 6 biologics in the United States, 52 biosimilars and 15 biologics in Germany, and 28 biosimilars and 13 biologics in Switzerland.

They analyzed temporal trends in the uptake of biosimilars and their relative prices, compared with the prices of biologics in each country, by obtaining wholesale acquisition costs from online drug pricing databases. They extracted quarterly sales volume data for 2011-2020 from the IQVIA database. In the case of confidential rebates in Switzerland, the researchers obtained list prices.

Overall, the uptake of biosimilars increased in all three countries during the study period. However, the prices of biosimilars and the reference products were significantly higher in the United States, compared with Germany and Switzerland, both of which have national mechanisms for drug price negotiation. The monthly treatment cost of biosimilars was a median of 1.94 and 2.74 times higher in the United States than in Germany and Switzerland, respectively.

On average, the biosimilar market share at launch was highest in Germany; however, it increased at the fastest rate in the United States.

The findings were limited by several factors, including the sample size and the inclusion only of sales data provided by IQVIA, and by the use of list prices only without accounting for drug rebates, the researchers noted. Other limitations were the inability to compare conclusions from the United States and European Union directly because the drugs entered markets at different times, and not all the same drugs have been approved or designated as biosimilars, they said.

However, the results illustrate a difference in uptake of biosimilars in the United States with a reduced impact on drug costs, they said.

Looking ahead, “Policies for drug pricing negotiations in the U.S. against anticompetitive practices of exclusionary contracts could allow biosimilars to enter the market sooner and at lower costs, which could result in lower health care costs and improved patient access,” they concluded.

The study was partially funded by the Swiss National Science Foundation. Lead author Mr. Carl had no financial conflicts to disclose; several coauthors disclosed funding from organizations including The Health Foundation, the U.K. National Institute for Health Research, and the Pharmaceutical Group of the European Union; all were unrelated to the current study.

Low energy–density diets that are based either on potatoes or beans similarly reduced insulin resistance in adults with poor blood glucose control, according to a controlled feeding study in 36 individuals.

PxHere

Potatoes have gotten a bad rap for their high glycemic index, but they have little fat and a low energy density, wrote the study investigators. In fact, “cooling of gelatinized potatoes generates appreciable levels of slowly digested starch (resistant starch type 3) and substantially lowers the blood glucose response that potatoes elicit.”

“There is a view that potatoes are a less healthy plant food, but there is very little empirical data from randomized trials to support this view,” senior investigator John P. Kirwan, PhD, said in an interview.

Dry beans and peas (known as pulses) also contain resistant starch that improves insulin sensitivity and glucose tolerance, and multiple studies support pulses as part of a low-glycemic diet to improve glucose control in adults, the researchers explained, but because the density of food often guides how much people eat, they hypothesized that potatoes could substitute for beans and provide similar glucose control benefits.

In a study published in the Journal of Medicinal Food, the researchers randomized 36 adults aged 18-60 years with insulin resistance to 8 weeks of a low energy–density diet (1 kcal/g) high in either potatoes or beans. The baseline body mass index ranged from 25 to 40 kg/m². Insulin resistance was defined using the homeostatic model assessment of insulin resistance (HOMA-IR) with a score greater than 2.

The controlled diet consisted of 50%-55% carbohydrates, 30%-35% fats, and 15%-20% protein. Each meal in the potato group included a side of potatoes, and each meal in the bean group included a side of beans.

The primary outcome was the mean change in blood glucose concentration; the researchers also assessed weight loss.

A total of 14 individuals in the potato group and 17 in the bean group completed the study; but data from the 18 individuals in each group were included in an intent-to-treat analysis.

Among study completers, HOMA-IR in the bean group showed an average decrease of 1.4 from baseline (P = .02 ); a similar decrease of 1.3 occurred in the potato group (P < .05) with no significant difference between the two diets.

Overall compliance with both diets was roughly 88%. Body weight reductions were similar in both groups and significantly reduced from baseline over the study period, with average reductions in intent-to-treat analysis of 5.82 kg in the potato group and 4.0 kg in the bean group. BMI also was significantly reduced from baseline in both potato and bean groups (2.04 kg/m² and 1.35 kg/m², respectively). Although baseline differences were not significant, “BMI at baseline was higher and the reduction in response to the treatment was significantly greater in the potato diet compared with the bean diet,” the researchers noted. The effect on blood glucose response was not significantly different between the two groups or from baseline, they said.

The findings were limited by several factors including the small size, relatively short study period, and controlled nature of the study diet, the researchers noted. “The addition of a typical Western diet would have enhanced our understanding of the effect of low energy–dense diets on metabolic outcomes,” they noted in their discussion.

However, both diets led to a reduction in body weight, and the low energy density of both potato and bean diets promoted weight loss without affecting appetite or requiring calorie restriction, the researchers explained. Therefore, “this weight loss if sustained over time could have a substantial impact on body weight,” they said.

“We hypothesized that there would be equivalence between the potato and bean diet and this hypothesis proved to be correct,” said Dr. Kirwan, of the Pennington Biomedical Research Center, Baton Rouge, La., in an interview.

The take-home message for clinicians is that, though small, the study was very well-controlled, Dr. Kirwan emphasized. “Clinicians ought to consider the health benefits of the potato when it is cooked and served appropriately.”

Looking ahead, larger randomized controlled trials with additional control arms, longer time of at least 12 weeks, and different patient populations are needed, Dr. Kirwan added.
 

Findings mitigate food myths

The debate continues about whether there are foods that are “good” or “evil;” or foods that one “should not eat” or “should eat,” said Amy Rothberg, MD, associate professor of internal medicine and of nutritional sciences at the University of Michigan, Ann Arbor, in an interview.

“This study dispels the myth that incorporating a small portion of potato into the diet (although these are not potatoes that are fried, or are topped with cheese, bacon, sour cream, etc.) results in deleterious metabolic outcomes when compared to a diet that is comprised of beans (pulses) as part of a low energy–dense diet,” she explained.

“The diet in both groups was of low energy density, which has been shown to result in fewer calories consumed, weight loss, and improvement in insulin resistance,” so the similarity in results was not so surprising, said Dr. Rothberg.  

For the clinical takeaway, Dr. Rothberg agreed with the study authors: “Clinicians may counsel their patients that they can still consume a small potato (with the caveat above regarding cooking methods and toppings) as part of a balanced meal so long as they are keeping their overall calories low and not exceeding their metabolic requirements based on body weight/BMI,” she said.

As for additional research, studies with a longer time frame and a larger and more diverse study population are needed, including populations with common insulin resistance comorbidities such as type 2 diabetes, fatty liver disease, and cardiovascular disease, Dr. Rothberg noted.
 

Consumer considerations, with caveats

The key message for consumers is that, “based on this very small study of short duration, consuming a small portion of potato as part of an overall balanced, low-energy diet did not produce adverse effects on glucose or insulin when compared to a diet of pulses known to have favorable effects on glucose and insulin,” Dr. Rothberg told this news organization. However, “consumers should note that, although the results from this small study are encouraging, it would be premature to extrapolate the findings from this study to other populations,” she said. Also, keep in mind that the study was supported in part by the Alliance for Potato Research, although the authors stated that none of the funders (Alliance for Potato Research and Education and the National Institutes of Health) had any role in the design, analysis, or writing of the article, she added.

The study was supported in part by the Alliance for Potato Research and Education and the National Institutes of Health, which funds the Louisiana Clinical and Translational Science Center. The researchers and Dr. Rothberg had no financial conflicts to disclose.
