Pediatric News

Although the only pediatric indication for chimeric antigen receptor T-cell therapy currently approved by the Food and Drug Administration is B-lineage acute lymphoblastic leukemia (ALL) that is refractory to at least two frontline induction attempts or is in second or later relapse, clinical trials of CAR-T therapy for pediatric solid tumors are also currently in progress, said Gregory Yanik, MD, from the CS Mott Children’s Hospital at the University of Michigan, Ann Arbor, at the Transplant & Cellular Therapies Meetings.

In his presentation, Dr. Yanik discussed progress in solid tumor studies as well as some issues involving the current use of CAR-T therapy for ALL.

Solid tumor studies

Malignancies such as sarcomas, brain tumors, and neuroblastomas pose unique challenges, “In contrast to hematologic malignancies, the protein we’re targeting may not be present on the cell surface of all the tumor cells. There are lower-expression profiles, and this is a problem. In fact, many people have postulated that with CAR-T for pediatric solid tumors we’ll have to do repeated cycles, almost like we do with chemotherapy,” he said at the meeting held by the American Society for Blood and Marrow Transplantation and the Center for International Blood and Marrow Transplant Research.

There are currently 14 studies of CAR-T for central nervous system tumors in children, targeting either epidermal growth factor receptor (EGFR) in glioblastoma multiforme and high-grade gliomas, HER2 in a variety of CNS tumors, the GD2 antigen on pontine gliomas, and the checkpoint molecular B7H3 in medulloblastomas and pontine gliomas.

“In sarcomas in kids there are currently 12 trials in progress. Most of the targeting epitopes are targeting either HER2 or GD2. Repetitive CAR-T infusions are being used in several of these trials in sarcomas.

For neuroblastomas there are currently 13 studies in progress, nearly all of which target GD2. Some of the trials include combining CAR-T with immune checkpoint inhibitors or C7R, an engineered cytokine driver designed to prevent T-cell exhaustion.

In addition, several trials of tumor pulsed dendritic cell vaccines are underway for treatment of children with Wilms tumor, Dr. Yanik noted.
 

Unresolved procedural questions

It’s still early days in CAR-T therapy, and there are several still unanswered questions regarding optimal therapy for and management of patients undergoing CAR-T procedures, Dr. Yanik said.

For example, the optimal time to collect T cells during apheresis is still unclear, he said. Collecting prior to reinduction therapy raises the risk of transducing leukemic cells, while collecting after reinduction may result in inadequate quantity or quality of cells. Regardless of when cells are collected, apheresis should be performed only when the absolute lymphocyte count is above 500/mcL or the CD3 count is above 150/mcL at the time of apheresis.

In the case tisagenlecleucel (Kymriah), his center typically collects 1x10⁹ CD3 cells regardless of age or weight.

The number of CAR T-cells infused also appears to matter, as responses are improved at CAR-T doses above 1.5x10⁶/kg, while risk for higher-grade cytokine release syndrome (CRS) occurs at higher infusion doses.
 

Blinatumomab or inotuzumab?

Along with CAR-T, two other agents, the bispecific T-cell engager blinatumomab (Blincyto) and the antibody conjugate inotuzumab ozogamicin (Besponsa) are also approved for the treatment of patients with relapsed/refractory B-cell ALL.

Like CAR-T therapy, the primary toxicities associated with blinatumomab are CRS and neurologic adverse events, whereas at inotuzumab is largely associated with hematologic and hepatic toxicities.

The logistics of therapy differ widely, with a 28-day infusion required for blinatumomab, compared with weekly dosing of inotuzumab, and the multiple visits for apheresis and infusion required for CAR-T.

Blinatumomab is approved for both children and adults with relapsed/refractory ALL, but inotuzumab is approved only for adults, and CAR-T with tisagenlecleucel is approved only for children in this indication.
 

CD-19 expression

There is evidence to suggest that CD19 expression prior to CAR-T has an effect on outcomes, Dr. Yanik said.

“Does blinatumomab pre–CAR-T impact outcome? The answer is probably yes,” he said.

He referred to a study by investigators at the Children’s Hospital of Philadelphia showing that, “if you’re giving blinatumomab prior to CAR-T therapy, you’re potentially reducing the cell-surface expression of CD19 on your leukemic blasts, and now while you’re bringing these patients in for CAR-T therapy, you’re getting a much higher population of dim CD19 expressers, and this is associated with a higher relapse rate and lower remission rate.”
 

Predicting relapse

Dr. Yanik referred to a study, currently unpublished, which will show that next-generation sequencing (NGS) is more sensitive than flow cytometry for detection of minimal residual disease (MRD), and that MRD analysis of marrow was more sensitive than analysis of peripheral blood.

“Poor outcomes were seen post CAR-T for patients who were in morphologic remission on day 28 or day 100, but had positive MRD. This especially held true if it was next-gen sequencing MRD-positive at day 100, for which relapse rates were over 95%,” he said.

The absence of B-cells is a surrogate marker for the persistence of CAR-T, and conversely, the recovery of CD19-positive B cells may be a predictor for relapse, especially if the B-cell recovery occurs within the first 6 months following CAR-T infusion.
 

Transplant after CAR-T?

Bone marrow transplant after CAR-T is recommend for patients with high risk of relapse, including those with B-cell recovery within the first 6 months after CAR-T, patients with MRD positivity at days 28 or 100, and patients with mixed lineage leukemia.

“Should we transplant good-risk patients, meaning, if you have NGS-MRD negative patients, is there a role for transplant? You have to look at the risk versus benefit there. These patients may have a cure rate that’s in the 80%-plus range, could we potentially optimize that even more if we consolidate them with an allo[geneic] transplant,” Dr. Yank said.
 

Move CAR-T up front?

A Children’s Oncology Group study is currently examining whether giving CAR-T therapy to patients with MRD of 0.01% or greater following first consolidation could result in lower tumor burden, fewer relapse, and less CRS with CAR-T.

Dr. Yanik reported that he had no conflicts of interest to disclose.

Several maternal chronic conditions increase the risk of giving birth to a child with cerebral palsy, based on data from more than 1.3 million Norwegian children.

Mothers with autoimmune disorders, such as diabetes and lupus, had the greatest risks, reported lead author Marianne S. Strøm, MD, of the University of Bergen (Norway) and colleagues.

“The etiologies of cerebral palsy are complex, and only a few prenatal risk factors have been identified,” the investigators wrote in Pediatrics. “Among these possible risk factors are maternal chronic conditions, although studies are typically underpowered and limited to one or two conditions.”

According to Dr. Strøm and colleagues, several components of maternal chronic conditions have been linked with cerebral palsy, including placental abnormalities, altered thrombotic state, and inflammation. Furthermore, mothers with chronic conditions are more likely to give birth prematurely and have children with congenital malformations, both of which have also been associated with cerebral palsy.

To date, however, “there has been no systematic description of maternal chronic conditions and risk of cerebral palsy in offspring,” the investigators noted.

The present, prospective cohort study aimed to meet this need with a population of 1,360,149 children born in Norway from 1990 to 2012, among whom 3,575 had cerebral palsy. Case data were extracted from the Norwegian Patient Registry and the National Insurance Scheme. Information about maternal chronic conditions was extracted from the Medical Birth Registry of Norway and the Norwegian Patient Registry, with the latter also providing information about paternal chronic conditions.

Using log binomial regression models, the investigators determined relative risks of having children with cerebral palsy among parents with chronic conditions versus parents from the general population. This revealed that chronic conditions in fathers had no correlation with cerebral palsy. In contrast, mothers with chronic conditions had a 30% increased risk (relative risk, 1.3; 95% confidence interval, 1.2-1.5), which could be further stratified by number of chronic conditions; mothers with one chronic condition, for instance, had a 20% increased risk (RR, 1.2; 95% CI, 1.1-1.4), while those with two chronic conditions had a 60% increased risk (RR, 1.6; 95% CI, 1.1-2.2), and those with more than two chronic conditions had triple the risk (RR, 3.1; 95% CI, 1.4-6.8)

“The lack of associations between the father’s chronic illness and cerebral palsy risk supports the interpretation that cerebral palsy risk in offspring is the direct result of the mother’s condition and not genetic predisposition or unmeasured situational factors,” the investigators wrote.

Maternal autoimmune conditions were particularly relevant, as they were associated with a 40% increased risk of cerebral palsy (RR, 1.4; 95% CI, 1.1-1.7), a rate that climbed dramatically, to 270%, among mothers with more than one autoimmune condition (RR, 2.7; 95% CI, 1.1-6.6).

“The role of autoimmune diseases in cerebral palsy risk (and maternal inflammation specifically) deserves closer attention,” the investigators wrote. “Using studies with larger sample sizes and a more clinical focus, including measures of placental structure and perinatal blood assays, researchers may be able to explore these possible connections between maternal autoimmune diseases and fetal neurodevelopment.”

Specifically, cerebral palsy in offspring was most strongly associated with maternal Crohn’s disease (RR, 2.1; 95% CI, 1.0-4.1), type 1 diabetes (RR, 2.2; 95% CI, 1.4-3.4), lupus erythematosus (RR, 2.7; 95% CI, 0.9-8.3), and type 2 diabetes (RR, 3.2; 95% CI, 1.8-5.4). Associations were also found for migraine (RR, 1.6; 95% CI, 1.2-2.2), multiple sclerosis (RR, 1.8; 95% CI, 0.8-4.4), and rheumatoid arthritis (RR, 2.0; 95% CI, 1.3-2.9). Several “weaker and less convincing associations” were detected for ulcerative colitis, thyroid disorder, epilepsy, asthma, anemia, and hypertension. Adjusting for parental education level, age, smoking status, and single-mother status did not significantly alter findings. Poisson and logistic regression models generated similar results.

In an accompanying editorial, Sandra Julsen Hollung, PhD, of the Cerebral Palsy Registry of Norway, Vestfold Hospital Trust, Tønsberg, and colleagues, advised that clinicians maintain perspective when discussing these findings with the general public.

“As the authors state, the absolute risk of cerebral palsy associated with at least one chronic maternal condition is low,” wrote Dr. Hollung and colleagues. “Among 1,000 pregnant women with any chronic and/or autoimmune disorder, more than 990 will deliver an infant who will not be diagnosed with cerebral palsy.”

They went on to emphasize that the study findings should not be viewed as firm evidence of causal relationships.

“Thus, the study cannot give clues to any specific preventive treatment,” wrote Dr. Hollung and colleagues. “However, if these disorders are part of a causal pathway, optimal treatment might reduce the risk of cerebral palsy.”

Although Dr. Hollung and colleagues advised that such efforts “would hardly affect the birth prevalence of cerebral palsy,” they also cited the Royal College of Obstetricians and Gynaecologists in the United Kingdom, noting that “each baby counts.”

Emeritus Professor Alastair MacLennan, AO, MB ChB, FRCOG, FRANZCOG, head of the Australian Collaborative Cerebral Palsy Research Group at the University of Adelaide (Australia) suggested that the findings may guide future research.

“An increasing proportion of cerebral palsy cases are being diagnosed by genome sequencing and other genetic techniques to have causative genetic variations,” Dr. MacLennan said. “The possibility of epigenetic interactions are also likely and are still to be investigated. Maternal disorders such as diabetes, lupus, or Crohn’s disease are possible epigenetic factors and this study helps to target these in future genetic and environmental studies of cerebral palsy causation. The days of attributing cerebral palsy to ‘birth asphyxia’ are over.”

The study was supported by the National Institutes of Health and the Western Norwegian Regional Health Authorities. The investigators reported no conflicts of interest.

Maternal autoimmune conditions were particularly relevant, as they were associated with a 40% increased risk of cerebral palsy (RR, 1.4; 95% CI, 1.1-1.7), a rate that climbed dramatically, to 270%, among mothers with more than one autoimmune condition (RR, 2.7; 95% CI, 1.1-6.6).

“The role of autoimmune diseases in cerebral palsy risk (and maternal inflammation specifically) deserves closer attention,” the investigators wrote. “Using studies with larger sample sizes and a more clinical focus, including measures of placental structure and perinatal blood assays, researchers may be able to explore these possible connections between maternal autoimmune diseases and fetal neurodevelopment.”

Specifically, cerebral palsy in offspring was most strongly associated with maternal Crohn’s disease (RR, 2.1; 95% CI, 1.0-4.1), type 1 diabetes (RR, 2.2; 95% CI, 1.4-3.4), lupus erythematosus (RR, 2.7; 95% CI, 0.9-8.3), and type 2 diabetes (RR, 3.2; 95% CI, 1.8-5.4). Associations were also found for migraine (RR, 1.6; 95% CI, 1.2-2.2), multiple sclerosis (RR, 1.8; 95% CI, 0.8-4.4), and rheumatoid arthritis (RR, 2.0; 95% CI, 1.3-2.9). Several “weaker and less convincing associations” were detected for ulcerative colitis, thyroid disorder, epilepsy, asthma, anemia, and hypertension. Adjusting for parental education level, age, smoking status, and single-mother status did not significantly alter findings. Poisson and logistic regression models generated similar results.

In an accompanying editorial, Sandra Julsen Hollung, PhD, of the Cerebral Palsy Registry of Norway, Vestfold Hospital Trust, Tønsberg, and colleagues, advised that clinicians maintain perspective when discussing these findings with the general public.

“As the authors state, the absolute risk of cerebral palsy associated with at least one chronic maternal condition is low,” wrote Dr. Hollung and colleagues. “Among 1,000 pregnant women with any chronic and/or autoimmune disorder, more than 990 will deliver an infant who will not be diagnosed with cerebral palsy.”

They went on to emphasize that the study findings should not be viewed as firm evidence of causal relationships.

“Thus, the study cannot give clues to any specific preventive treatment,” wrote Dr. Hollung and colleagues. “However, if these disorders are part of a causal pathway, optimal treatment might reduce the risk of cerebral palsy.”

Although Dr. Hollung and colleagues advised that such efforts “would hardly affect the birth prevalence of cerebral palsy,” they also cited the Royal College of Obstetricians and Gynaecologists in the United Kingdom, noting that “each baby counts.”

Emeritus Professor Alastair MacLennan, AO, MB ChB, FRCOG, FRANZCOG, head of the Australian Collaborative Cerebral Palsy Research Group at the University of Adelaide (Australia) suggested that the findings may guide future research.

“An increasing proportion of cerebral palsy cases are being diagnosed by genome sequencing and other genetic techniques to have causative genetic variations,” Dr. MacLennan said. “The possibility of epigenetic interactions are also likely and are still to be investigated. Maternal disorders such as diabetes, lupus, or Crohn’s disease are possible epigenetic factors and this study helps to target these in future genetic and environmental studies of cerebral palsy causation. The days of attributing cerebral palsy to ‘birth asphyxia’ are over.”

The study was supported by the National Institutes of Health and the Western Norwegian Regional Health Authorities. The investigators reported no conflicts of interest.

In his role as head of the division of pediatric behavioral health at National Jewish Health, Denver, Bruce G. Bender, PhD, helps children and adults navigate the adverse effects of severe atopic dermatitis (AD) on their quality of life.

“There have been many surveys of adults with AD who report impairment of their sleep, reduced activity level, increased work absence, financial burden, emotional distress, and social avoidance,” he said at the Revolutionizing Atopic Dermatitis virtual symposium. “Similarly, children with AD or their parents report emotional distress, reduced activity, and increased school absence, social avoidance, and sleep disturbance. Families report financial burdens, conflict, particularly among the adults, social avoidance, sleep disturbance in the parents, and reduction of well-being in the siblings.”

Getting adequate sleep is especially challenging for patients with AD, and loss of sleep can have serious daytime consequences. In an effort to objectively measure sleep change in this population, Dr. Bender and colleagues recruited 14 adults with AD and 14 healthy controls who wore an ActiGraph for 1 week and completed questionnaires about sleep, itch, and quality of life. Patients with AD were awake almost twice as many minutes each night as the healthy controls (a mean of 57.3 vs. 32.3 minutes, respectively; P = .0480). Consequently, their sleep efficiency was significantly reduced based on the Pittsburgh sleep quality index (a mean of 90.6 vs. 95; P = .0305).

In another study, Dr. Bender and colleagues enrolled 20 adults with AD who underwent 2 nights of polysomnography and actigraphy. The lab was set up to measure a scratching event, which was recorded when a burst of electromyographic activity of at least 3 seconds was accompanied by a visible scratching motion. “We learned that sleep efficiency as measured by both PSG and actigraphy correlated with total body surface area and scratching index,” he said. “As we might assume, the more skin involved, the more patients scratch, the less well they sleep.”
 

Behavioral, neurocognitive effects

In a separate study of AD, sleep, and behavior, the researchers studied 1,041 children with asthma who were enrolled in the Childhood Asthma Management Program at eight North American sites. They used baseline parent ratings on standardized sleep and behavior rating scales and found that increased awakenings were associated with increased school absence and daytime behavior problems. “So, not only do children with AD sleep less well, but this shows up to impair their functioning during the day,” said Dr. Bender, professor of psychiatry at the University of Colorado, Denver.

In a report from Australia, researchers set out to explore the association between sleep and neurocognitive function in 21 children with eczema and 20 healthy controls. Participants underwent cognitive testing and polysomnography. The authors found that the children with eczema demonstrated lower test scores. Reduced scores were correlated with parental reports of sleep problems but not polysomnography.

In a much larger study funded by the Agency for Healthcare Research and Quality, investigators analyzed data on 354,416 children and 34,613 adults from 19 U.S. population surveys including the National Health Interview Survey 1997-2013 and the National Survey of Children’s Health 2003/4 and 2007/8. They found that AD was associated with ADHD in children (adjusted odds ratio, 1.14) and adults (aOR, 1.61). Higher odds of ADHD were found in children who had significant sleep disturbance (aOR, 16.83) and other allergic disease and asthma (aOR, 1.61).

“All of these findings show that AD can impact quality of life, especially sleep, with the result of poorer daytime functioning,” Dr. Bender said. “But those studies don’t answer this question: Are patients with AD at increased risk for psychological disorders such as depression and anxiety?”
 

Impact on depression, anxiety

Two systematic reviews on the topic suggest that patients with AD are twice as likely to experience depression. One was published in 2018 and the other in 2019. The 2018 review reported a little more than a twofold increase (OR, 2.19), the 2019 review a little bit less (OR, 1.71).

“At the more severe end of the depression continuum, we sometimes see suicidal ideation and suicide attempts,” Dr. Bender said. “A number of studies have asked whether these are increased in patients with AD. Quite a few studies collectively show an increased incidence of suicidal ideation. The question of suicide attempts is reflected in fewer studies. And while the result is small, it is significant. There is a significant increase reported of suicide attempts in AD patients.”

The 2018 review also found an increased incidence of anxiety in AD patients: a little more than twofold in adults (OR, 2.19) and a little less than twofold in children (OR, 1.81).

“It’s a two-way relationship between AD and psychological factors,” Dr. Bender said. “We generally think about AD – the stress that it brings, the burden that it puts on children, adults, and families. But it can work the other way around,” he said, referring to patients who have psychological problems, experience a great deal of stress, have trouble being adherent to their treatment regimen, and find it difficult to resist scratching. “The behavioral/psychological characteristics of the patient also drive the AD. It is well established that acute and chronic stress can result in a worsening of skin conditions in AD patients.”

Behavioral health interventions that have been described in the literature include cognitive therapy, stress management, biofeedback, hypnotherapy, relaxation training, mindfulness, habit reversal, and patient education – some of which have been tested in randomized trials. “All of them report a decrease in scratching as a consequence of the behavioral intervention,” Dr. Bender said.

“Other studies have been reported that look at the impact of behavioral interventions on the severity of the skin condition. Most report an improvement in the skin condition from these behavioral interventions but it’s not a perfect literature.” Critiques of these studies include the fact that there is often not enough detail about the intervention or the framework for the intervention that would allow a clinician to test an intervention in another study or actually pull that intervention into clinical practice (Cochrane Database Syst Rev. 2014 Jan 7;2014[1]:CD004054), (Int Arch Allergy Immunol.2007;144[1]:1-9).

“Some of the studies lack rigorous designs, some have sampling bias, and some have inadequate outcome measurements,” he said. “We really need additional, high-quality studies to look at what is helpful for patients with AD.”

Metformin has a modest favorable effect on body mass index z score and insulin resistance in children and adolescents with obesity, compared with placebo, according to a systematic review of trial data.

moodboard/thinkstockphotos

“The available evidence is of varying quality,” however, and the drug increases the likelihood of gastrointestinal adverse effects, reported Reem Masarwa, PharmD, PhD, and colleagues in Pediatrics. “Nonetheless, metformin may be considered for use as a pharmacologic therapy in this pediatric population because of its modest efficacy, availability, cost, and safety profile.”

The Food and Drug Administration has approved metformin for the treatment of type 2 diabetes in children and adolescents. Doctors have used the drug off label for weight loss in children with obesity, but this use “remains controversial,” the review authors said.

To assess the efficacy and safety of metformin plus lifestyle interventions compared with placebo plus lifestyle interventions in children and adolescents with obesity, Dr. Masarwa, with the Center for Clinical Epidemiology, Lady Davis Institute, Jewish General Hospital, and the department of epidemiology, biostatistics, and occupational health, McGill University, Montreal, and colleagues systematically reviewed data from randomized controlled trials (RCTs). Their review was published online in Pediatrics.

The investigators focused on studies that examined outcomes such as body mass index, BMI z score, insulin resistance, and gastrointestinal adverse effects. They excluded studies of children with type 2 diabetes.

The researchers included 24 RCTs in their review. The studies included 1,623 children and adolescents who received metformin (861 participants) or placebo (762 participants). Indications included uncomplicated obesity in 10 studies, obesity with insulin resistance in 9 studies, prediabetes in 3 studies, and nonalcoholic fatty liver disease in 2 studies. One of the trials did not incorporate a lifestyle cointervention.

Participants ranged in age from 4 years to 19 years, and trial durations ranged from 2 months to 2 years. The total daily dose of metformin ranged from 500 mg to 2,000 mg.

In 14 RCTs that reported BMI, metformin generally decreased BMI (range of mean changes: –2.70 to 1.30), compared with placebo (range of mean changes: –1.12 to 1.90), although three trials suggested that metformin increased BMI. The average difference in the treatment effect between the metformin and placebo groups ranged from –2.72 to 0.70. “Importantly, the authors of many RCTs reported variable treatment effects, preventing definitive conclusions from being drawn from individual trials,” Dr. Masarwa and coauthors wrote.

In seven RCTs that reported BMI z score, metformin consistently decreased BMI z score (range of mean changes: –0.37 to –0.03), compared with placebo (range of mean changes: –0.22 to 0.15). The mean difference in the treatment effect between treatment groups ranged from –0.15 to –0.07. The largest decrease occurred in patients with nonalcoholic fatty liver disease.

The rate of gastrointestinal adverse events nearly doubled with metformin treatment, relative to placebo (rate range: 2%-74% for metformin vs. 0%-42% for placebo).

Metformin adherence rates ranged from 60% to 90%, and lifestyle cointerventions varied substantially across the trials, the researchers noted. The clinical significance and long-term effects of metformin treatment in this population “remain uncertain,” they said.
 

Off-label use may not be ideal

“Ideally, children with obesity should be entered into a clinical trial rather than placed on an off-label medication,” Vandana Raman, MD, and Carol M. Foster, MD, said in a related commentary. Still, treatment with metformin may be reasonable in certain cases, said Dr. Raman and Dr. Foster of the division of endocrinology in the department of pediatrics at the University of Utah in Salt Lake City. “Metformin is a low-cost option and may provide modest clinical benefit for weight loss with minimal side effects. If lifestyle modification has been pursued but has achieved minimal weight loss, it may be reasonable to try an agent such as metformin as adjunctive therapy,” they said.

Lifestyle modification therapy – including nutritional changes, physical activity, and behavior modification – has been the “mainstay of management” for patients with obesity, and this approach underpins successful weight loss, they said. But durable weight loss with lifestyle modification may be challenging, and pharmacologic treatments “are attractive options before proceeding to bariatric surgery,” they said.

For younger patients, FDA-approved medications for obesity include orlistat and liraglutide for patients aged 12 years and older, and phentermine for patients aged 16 years and older.

“Orlistat has been associated with modest BMI reduction but may cause intolerable gastrointestinal side effects and possible fat-soluble vitamin deficiency,” they said. “Phentermine is approved for short-term therapy only and may increase heart rate and blood pressure and cause irritability and insomnia.”

Liraglutide, which was approved for the treatment of pediatric obesity in December 2020, reduced BMI in a trial that included adolescents with obesity. About 43% of the participants who received liraglutide, compared with 18% who received placebo, had a 5% reduction in BMI. In addition, 26% and 8%, respectively, had a 10% reduction in BMI. The use of liraglutide “is limited by the need for daily subcutaneous injections and high frequency of gastrointestinal side effects and high cost,” however, the commentary authors noted.

In addition, the FDA has approved setmelanotide for children older than 6 years with obesity caused by three rare genetic conditions.

Some small studies have suggested that topiramate may lead to meaningful weight loss in children, but the medication has been associated with cognitive dysfunction, they said.
 

Considering surgery

“This is an important review of the efficacy of metformin as a tool for weight loss in children with obesity,” said Suzanne C. Boulter, MD, adjunct professor emeritus of pediatrics and community and family medicine at the Geisel School of Medicine at Dartmouth in Hanover, N.H. “Results showed modest decreases in BMI z scores compared to placebo but there were a significant percentage of GI side effects and dropouts from the trials.”

“Tools other than lifestyle changes are needed to address” pediatric obesity, Dr. Boulter said. “Another tool is gastric bypass which is now a recommended intervention in selected clinical sites for adolescents 14 years of age and older with BMIs greater than 35.”

Dr. Boulter highlighted a recent study in Pediatrics that examined data from more than 200 adolescents who underwent bariatric surgery. The researchers found that outcomes were similar for older and younger patients.

“It would be interesting to pediatricians in practice to see a comparison study between metformin and bariatric surgery long-term results,” Dr. Boulter added.

Dr. Masarwa and coauthors received support from the Quebec Foundation for Health Research and the Canadian Institutes of Health Research Drug Safety and Effectiveness Cross-Disciplinary Training Program. One coauthor also is supported by an award from McGill University.

The authors of the systematic review and the accompanying commentary had no relevant financial disclosures. Dr. Boulter is a member of the editorial advisory board for Pediatric News and had no relevant financial disclosures.

If lifestyle modification has been pursued but has achieved minimal weight loss, it may be reasonable to try an agent such as metformin as adjunctive therapy,” they said.

Lifestyle modification therapy – including nutritional changes, physical activity, and behavior modification – has been the “mainstay of management” for patients with obesity, and this approach underpins successful weight loss, they said. But durable weight loss with lifestyle modification may be challenging, and pharmacologic treatments “are attractive options before proceeding to bariatric surgery,” they said.

For younger patients, FDA-approved medications for obesity include orlistat and liraglutide for patients aged 12 years and older, and phentermine for patients aged 16 years and older.

“Orlistat has been associated with modest BMI reduction but may cause intolerable gastrointestinal side effects and possible fat-soluble vitamin deficiency,” they said. “Phentermine is approved for short-term therapy only and may increase heart rate and blood pressure and cause irritability and insomnia.”

Liraglutide, which was approved for the treatment of pediatric obesity in December 2020, reduced BMI in a trial that included adolescents with obesity. About 43% of the participants who received liraglutide, compared with 18% who received placebo, had a 5% reduction in BMI. In addition, 26% and 8%, respectively, had a 10% reduction in BMI. The use of liraglutide “is limited by the need for daily subcutaneous injections and high frequency of gastrointestinal side effects and high cost,” however, the commentary authors noted.

In addition, the FDA has approved setmelanotide for children older than 6 years with obesity caused by three rare genetic conditions.

Some small studies have suggested that topiramate may lead to meaningful weight loss in children, but the medication has been associated with cognitive dysfunction, they said.
 

Considering surgery

“This is an important review of the efficacy of metformin as a tool for weight loss in children with obesity,” said Suzanne C. Boulter, MD, adjunct professor emeritus of pediatrics and community and family medicine at the Geisel School of Medicine at Dartmouth in Hanover, N.H. “Results showed modest decreases in BMI z scores compared to placebo but there were a significant percentage of GI side effects and dropouts from the trials.”

“Tools other than lifestyle changes are needed to address” pediatric obesity, Dr. Boulter said. “Another tool is gastric bypass which is now a recommended intervention in selected clinical sites for adolescents 14 years of age and older with BMIs greater than 35.”

Dr. Boulter highlighted a recent study in Pediatrics that examined data from more than 200 adolescents who underwent bariatric surgery. The researchers found that outcomes were similar for older and younger patients.

“It would be interesting to pediatricians in practice to see a comparison study between metformin and bariatric surgery long-term results,” Dr. Boulter added.

Dr. Masarwa and coauthors received support from the Quebec Foundation for Health Research and the Canadian Institutes of Health Research Drug Safety and Effectiveness Cross-Disciplinary Training Program. One coauthor also is supported by an award from McGill University.

Metformin has a modest favorable effect on body mass index z score and insulin resistance in children and adolescents with obesity, compared with placebo, according to a systematic review of trial data.

“The available evidence is of varying quality,” however, and the drug increases the likelihood of gastrointestinal adverse effects, reported Reem Masarwa, PharmD, PhD, and colleagues in Pediatrics. “Nonetheless, metformin may be considered for use as a pharmacologic therapy in this pediatric population because of its modest efficacy, availability, cost, and safety profile.”

The Food and Drug Administration has approved metformin for the treatment of type 2 diabetes in children and adolescents. Doctors have used the drug off label for weight loss in children with obesity, but this use “remains controversial,” the review authors said.

To assess the efficacy and safety of metformin plus lifestyle interventions compared with placebo plus lifestyle interventions in children and adolescents with obesity, Dr. Masarwa, with the Center for Clinical Epidemiology, Lady Davis Institute, Jewish General Hospital, and the department of epidemiology, biostatistics, and occupational health, McGill University, Montreal, and colleagues systematically reviewed data from randomized controlled trials (RCTs). Their review was published online in Pediatrics.

The investigators focused on studies that examined outcomes such as body mass index, BMI z score, insulin resistance, and gastrointestinal adverse effects. They excluded studies of children with type 2 diabetes.

The researchers included 24 RCTs in their review. The studies included 1,623 children and adolescents who received metformin (861 participants) or placebo (762 participants). Indications included uncomplicated obesity in 10 studies, obesity with insulin resistance in 9 studies, prediabetes in 3 studies, and nonalcoholic fatty liver disease in 2 studies. One of the trials did not incorporate a lifestyle cointervention.

Participants ranged in age from 4 years to 19 years, and trial durations ranged from 2 months to 2 years. The total daily dose of metformin ranged from 500 mg to 2,000 mg.

In 14 RCTs that reported BMI, metformin generally decreased BMI (range of mean changes: –2.70 to 1.30), compared with placebo (range of mean changes: –1.12 to 1.90), although three trials suggested that metformin increased BMI. The average difference in the treatment effect between the metformin and placebo groups ranged from –2.72 to 0.70. “Importantly, the authors of many RCTs reported variable treatment effects, preventing definitive conclusions from being drawn from individual trials,” Dr. Masarwa and coauthors wrote.

In seven RCTs that reported BMI z score, metformin consistently decreased BMI z score (range of mean changes: –0.37 to –0.03), compared with placebo (range of mean changes: –0.22 to 0.15). The mean difference in the treatment effect between treatment groups ranged from –0.15 to –0.07. The largest decrease occurred in patients with nonalcoholic fatty liver disease.

The rate of gastrointestinal adverse events nearly doubled with metformin treatment, relative to placebo (rate range: 2%-74% for metformin vs. 0%-42% for placebo).

Metformin adherence rates ranged from 60% to 90%, and lifestyle cointerventions varied substantially across the trials, the researchers noted. The clinical significance and long-term effects of metformin treatment in this population “remain uncertain,” they said.
 

Off-label use may not be ideal

“Ideally, children with obesity should be entered into a clinical trial rather than placed on an off-label medication,” Vandana Raman, MD, and Carol M. Foster, MD, said in a related commentary. Still, treatment with metformin may be reasonable in certain cases, said Dr. Raman and Dr. Foster of the division of endocrinology in the department of pediatrics at the University of Utah in Salt Lake City. “Metformin is a low-cost option and may provide modest clinical benefit for weight loss with minimal side effects.

A 16-year-old patient sits in front of you and says, “I think I’m transgender.”

Origovisualis/Getty Images

What do you do?

Whether you are an endocrinologist, family physician, pediatrician, or emergency physician, it’s probably a situation for which medical school education did not sufficiently prepare you. What you know is that you want to do your best to guide your patient and offer every resource necessary for a healthy and happy life. The good news is that your patient trusted you enough to disclose this information to you.

Sadly, this isn’t always the case. About 23% of transgender adults responding to the 2015 U.S. Transgender Survey put off necessary health care because they fear being mistreated or disrespected. Nearly one-third (31%) of survey respondents reported that none of their health care providers knew they were transgender.

Now that your patient feels comfortable enough with you to share this information, you must make sure you do everything in your power to continue to earn your patient’s trust.
 

Language matters

First, make sure that you are respectful with your terminology. Ask the patient for their name, pronouns, and gender identity. For example: “My name is Dr. Pine, and my pronouns are she/her. What are your pronouns? How do you describe your gender identity?” Each person may have terminology that is specific to their own experience, so allowing people to use their own language is the most respectful method.

People may identify as male, female, transwoman, transman, gender fluid, nonbinary, agender, neutrois, pangender, two-spirit, or other options not listed here. Physicians can be supportive by ensuring that their paperwork or electronic medical systems are sensitive to the needs of the transgender community. Having an option for the patient’s chosen name is courteous to all patients, regardless of gender identity; not everyone uses their legal name in everyday conversation.

Paperwork and electronic medical systems should ask for gender identity and sex assigned at birth, allow write-in options for issues of gender and sexual orientation, and ask for an anatomical inventory or organ inventory so that cancer screening can be conducted for the appropriate body parts.
 

Questions to ask

Ask patients about their gender journey: How long have they felt this way? How did they come to understand themselves and their gender? When did they start to disclose their experience with others? With pediatric patients, I ask if they have discussed this with their parents/guardians, and if they would like to have that conversation together.

Ask how you can support the patient on their journey. Are they interested in therapy, puberty blockers, hormones, or surgery? People may seek therapy for help coping with internalized transphobia, family rejection, or stigma. They may also want information or support with accessing hormones or surgery. In addition to individual therapy, there are numerous support groups for children, individuals, parents/guardians, and partners, such as PFLAG.org and Genderspectrum.org.

If you are the right kind of doctor and ready to prescribe, you can begin counseling. If not, you should know how to find local resources. The World Professional Association for Transgender Health has a directory of providers, and there are other resources listed below.
 

What does gender transitioning entail?

There are many components to gender transition. Some transitions may consist primarily of a social transition, with people using a different name, pronouns, and external expression, such as hairstyle and clothing. For others, there may be a medical component.

Mental health care is also an important component of gender transition for children, adolescents, adults, and family members. Mental health concerns are significantly greater in transgender and gender-nonconforming people, with higher rates of depression, anxiety, suicidal ideation, self-harm, substance abuse, eating disorders, and neurodiversity on the autism spectrum. In a study of more than 6,400 transgender people in the United States, 41% reported attempting suicide – a rate 25 times higher than that of the general population. Numerous studies show that hormonal treatment decreases depression, suicidal ideation, and anxiety, and also improves quality of life.

One common misperception, especially when working with children, is that youth transition involves a “sex change” (an outdated term) or any type of surgery. In reality, the main intervention before puberty is psychological support and social transition. The use of a chosen name at school, home, work, and with friends was shown to be associated with lower depression, suicidal ideation, and suicidal behavior. Another study demonstrated that children supported in their identities have mental health similar to that of cisgender siblings and peers.

When puberty approaches, if there is distress around natal pubertal development, then gonadotropin-releasing hormone agonists or “puberty blockers” may be used to temporarily pause the pubertal process, but only after Tanner stage II-III is reached. These medications have been safely used for decades for patients with central precocious puberty. Access to puberty-blocking medication in adolescence (when desired) has been associated with lower rates of suicidal ideation in adulthood and can truly be a lifesaving intervention.

When teens are older, they may choose to take gender-affirming hormone therapy to go through the puberty that is concordant with their affirmed gender. Adults who decide to transition medically may decide to take hormone therapy and may have gender-confirmation surgery, if desired, to align the body with their gender identity and alleviate gender dysphoria. Overall, access to medical care and hormone therapy have been shown to decrease depression, anxiety, and suicidality, and improve quality of life.
 

Sexuality and fertility

It is important to understand that sexuality is separate from gender identity, and that attraction and sexual activity cannot be assumed. Take a sensitive romantic and sexual history from your patient to get the information necessary to counsel patients about safe relationships and sexual practices. It is important not to make assumptions; a patient who is asexual may still be having sex, and a transgender man may be having receptive vaginal intercourse and may need information about contraception and family planning.

Also, be careful about using clinical language. Some people may want to use anatomical terms, but others may be uncomfortable or triggered by them. For instance, a transgender man may use “chest” for breasts, or “genital canal,” and “junk,” “dick,” or “front hole” for the vagina. Ask patients what terms they prefer to use.

It is also important to consider the impact that medical and surgical interventions may have on fertility, especially when discussing the topic with children and adolescents who may not have spent much time thinking about family planning. Be careful not to make assumptions about plans for parenthood, and remember that there are many paths to becoming a parent.
 

What does the patient need right now?

When I was a fourth-year medical student on my outpatient child psychiatry rotation, a 5-year-old child assigned male at birth was guarded and frightened of me until their mother said: “It’s okay, Dr. Elyse likes girl things too,” at which point the child became animated and happy while chatting with me about Barbie dolls. My patient had already endured teasing about gender nonconformity, starting in kindergarten; it was unclear to my patient whether I would be a safe person or a bully.

The mother was kind and affirming, but she also wanted answers. Would her child grow up to be a gay man? Or a transgender woman? Would her child be able to live freely, or would they always be quiet around others, scared of what people might say? Would her child be safe?

We can’t predict the future, but as doctors, we want to use all of our knowledge and tools to help our patients live healthy lives. In this case, it meant helping the mother know how to support her child’s identity, how to advocate for a safe school and community, where to connect with other gender-creative children, and how to tolerate ambiguity and celebrate the child she has, not the child she expected.

We know that people with higher support and higher self-esteem can have greater resilience and greater success. This family may need medical resources for puberty blockers, hormone therapy, and even surgery someday, but reassurance is what was needed in the moment. When your patient comes out to you, they are trusting you. It is your obligation and privilege as a medical professional to help them begin a journey to an authentic life.

One dose of the novel agent, REGN1908-1909 (Regeneron Pharmaceuticals) resulted in a rapid and durable reduction in cat-allergen-induced bronchoconstriction in cat-allergic subjects with mild asthma.

The finding, from a phase 2 randomized placebo-controlled study, is good news for the millions of people who are plagued by cat allergies, the investigators say.

The study, which was sponsored by Regeneron, was presented in a late breaking oral abstract session at the annual meeting of the American Academy of Allergy, Asthma, and Immunology, held virtually this year.

“REGN1908-1909 contains antibodies against Fel d 1, the major cat allergen, and here we show that it quickly and lastingly reduces acute bronchoconstriction in people with cat allergy,” lead author Frederic J. de Blay, MD, Strasbourg University Hospital, France, said in an interview.

Dr. de Blay admitted he is “quite excited” about the results.

“This study was performed in an environmental exposure chamber, and we clearly demonstrate that these antibodies decrease the asthmatic response to cat allergen within 8 days, and that these effects last 3 months. I never saw that in my life. I was a little bit skeptical at first, so to obtain such robust results after just 8 days, after just one injection, I was very surprised,” he said.

Dr. de Blay and his team screened potential participants to make sure they were cat allergic by exposing them to cat allergen for up to 2 hours while they were in the environmental exposure chamber. To be eligible for the study, participants had to show an early asthmatic response (EAR), defined as a reduction in forced expiratory volume in 1 second (FEV₁₎ of at least 20% from baseline.

The participants were then randomized to receive either single-dose REGN1908-1909, 600 mg, subcutaneously (n = 29 patients) or placebo (n = 27 patients) prior to cat-allergen exposure in the controlled environmental chamber.

Dr. de Blay developed the chamber used in the study: the ALYATEC environmental exposure chamber.

“The chamber is 60 meters square, or 150 cubic meters, and can accommodate 20 patients. We are able to nebulize cat allergen, mice allergen, or whatever we wish to study so we can standardize the exposure. We can control the particle size and the amount so we know the exact amount of allergen that the patient has been exposed to,” he explained.

To test the efficacy of REGN1908-1909 in reducing acute bronchoconstriction, or EAR, the researchers measured FEV₁ at baseline, and on days 8, 29, 57, and 85 in both groups. During each exposure, measurements were taken every 10 minutes for periods that lasted up to 4 hours.

They found that the probability of remaining in the chamber with no asthmatic response was substantially elevated in the group treated with REGN1908-1909.

Compared with placebo, REGN1908-1909 significantly increased the median time to EAR, from 51 minutes at baseline to more than 4 hours on day 8, (hazard ratio [HR], 0.36; P < .0083), day 29 (HR, 0.24; P < .0001), day 57 (HR, 0.45; P = .0222), and day 85 (HR, 0.27; P = .0003).

The FEV₁ area under the curve (AUC) was also better with REGN1908-1909 than with placebo at day 8 (15.2% vs. 1.6%; P < .001). And a single dose reduced skin-test reactivity to cat allergen at 1 week, which persisted for up to 4 months.

In addition, participants who received REGN1908-1909 were able to tolerate a threefold higher amount of the cat allergen than those who received placebo (P = .003).

“We initially gave 40 nanograms of cat allergen, and then 8 days later they were able to stay longer in the chamber and inhale more of the allergen, to almost triple the amount they had originally been given. That 40 nanograms is very close to real world exposure,” Dr. de Blay noted.

Regeneron plans to start a phase 3 trial soon, he reported.
 

Promising results

“The study is well designed and shows a reduction in drop of FEV₁ in response to cat allergen provocation and a decreased AUC in cat SPT response over 4 months,” Jonathan A. Bernstein, MD, professor of medicine at the University of Cincinnati, said in an interview.

“These are very promising results, which show that REGN1908-1909 can be a novel treatment for cat-induced asthma, which is often the only sensitization patients have. And they love their cats – one-third of the U.S. population has a cat and one-third has a dog, and 50% have both,” noted Dr. Bernstein, who was not involved with the study.

“This novel study used our scientific knowledge of the cat allergen itself to design a targeted antibody-based treatment that demonstrates significant benefit even after the first shot,” added Edwin H. Kim, MD, director of the UNC Food Allergy Initiative at the University of North Carolina at Chapel Hill.

“This strategy has the potential to revolutionize not only our treatment of common environmental allergies but also other allergic diseases with well-described triggers, such as food and drug allergy,” Dr. Kim, who was not part of the study, said in an interview.

Dr. de Blay reported a financial relationship with Regeneron Pharmaceuticals, which sponsored the study. Dr. Bernstein and Dr. Kim have disclosed no relevant financial relationships.

Adalimumab has received approval from the Food and Drug Administration for use in pediatric patients aged 5 years and older with moderately to severely active ulcerative colitis (UC), according to a press release from manufacturer AbbVie.

Approval was based on data from the phase 3 ENVISION 1 randomized, double-blind study (NCT02065557) in which 60% of patients receiving the higher induction dose showed clinical remission according to Partial May Score (PMS) at 8 weeks, 45% of whom were in remission according to Full Mayo Score (FMS) at 1 year. The approval means that children with UC and their families have the option of a subcutaneous biologic that can be administered at home.

In the ENVISION 1 study, clinical remission was defined as a PMS (based on stool frequency, rectal bleeding, and physician’s global assessment) ranging from 0 to 3 at the end of the 8-week induction period or FMS (which adds endoscopy) at the end of 52 weeks as less than or equal to 2 points total, with no individual subscore greater than 1. The study included children aged 4-17 years with active UC who were randomized to a low-dose or high-dose group.

“Through week 8, patients in both dosage groups received 2.4 mg/kg (maximum of 160 mg) at week 0, 1.2 mg/kg (maximum of 80 mg) at week 2, and 0.6 mg/kg (maximum of 40 mg) at weeks 4 and 6. The higher-dosage group also received an additional dosage of 2.4 mg/kg (maximum of 160 mg) at week 1,” according to the company press release. Between weeks 8 and 52, patients received double-blind placebo or 0.6 mg/kg adalimumab (maximum of 40 mg) every other week (maintenance standard dose) or every week (maintenance high dose). 

No new adalimumab safety signals were noted in the study; headache and worsening UC were the most frequently reported treatment-emergent adverse events, and 22.6% of patients experienced a serious adverse event. “No deaths, malignancies, active tuberculosis or demyelinating disease were observed in this study,” according to the company. Full prescribing information can be found on the FDA website.
 

Approval expands options

“The number of FDA-approved biologics to treat pediatric UC has been limited,” said Atsushi Sakuraba, MD, PhD, an inflammatory bowel disease specialist at the University of Chicago, in an interview. “Infliximab is approved for pediatric UC and CD [Crohn’s disease], but adalimumab was only approved for CD in pediatric patients, and vedolizumab and ustekinumab are approved for neither UC nor CD in pediatric patients,” he said. “Thus, the addition of adalimumab as a treatment option for pediatric UC is of great benefit for pediatricians and patients.”

The approval will impact clinical practice in several ways, Dr. Sakuraba said. “Adalimumab may be used for those who lose response to infliximab, but may also be used as a first-line biologic because it is self-injectable,” he emphasized. Given that adalimumab is already in use for pediatric patients with Crohn’s disease, Dr. Sakuraba said he does not see any barriers to implementation of its use for children with UC. In addition, “the potential for better disease control, reduction of disease-related complications, and improved quality of life outweighs the risk of adverse reactions,” Dr. Sakuraba said. “The news of no new safety concern in the 52-week study period further supports the safety of biologic treatment in pediatric patients,” he added.

As for additional research: “It remains to be determined whether combination therapy with an immunomodulator would be more effective than monotherapy, and also whether there are any additional risks of adverse events with the addition of immunomodulators such as long-term risk of malignancy, especially lymphoproliferative disorders,” Dr. Sakuraba noted. “Therapeutic options for pediatric [inflammatory bowel disease] are limited and lagging, compared to adult patients, so studies of non-TNF [tumor necrosis factor] biologics such vedolizumab and ustekinumab are also awaited,” he said.

Dr. Sakuraba had no financial conflicts to disclose.

The number of new COVID-19 cases in children declined for the sixth consecutive week, but the drop was the smallest yet, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

New child cases in the United States totaled 64,264 for the week of Feb. 19-25, down from 70,640 the week before. That drop of almost 6,400 cases, or 9.0%, falls short of the declines recorded in any the previous 5 weeks, which ranged from 18,000 to 46,000 cases and 15.3% to 28.7%, based on data from the heath departments of 49 states (excluding New York), as well as the District of Columbia, New York City, Puerto Rico, and Guam.

The total number of children infected with SARS-CoV-2 is up to almost 3.17 million, which represents 13.1% of cases among all age groups. That cumulative proportion was unchanged from the previous week, which has occurred only three other times over the course of the pandemic, the AAP and CHA said in their weekly COVID-19 report.

Despite the 6-week decline in new cases, however, the cumulative rate continued to climb, rising from 4,124 cases per 100,000 children to 4,209 for the week of Feb. 19-25. The states, not surprisingly, fall on both sides of that national tally. The lowest rates can be found in Hawaii (1,040 per 100,000 children), Vermont (2,111 per 100,000), and Maine (2,394), while the highest rates were recorded in North Dakota (8,580), Tennessee (7,851), and Rhode Island (7,223), the AAP and CHA said.

The number of new child deaths, nine, stayed in single digits for a second consecutive week, although it was up from six deaths reported a week earlier. Total COVID-19–related deaths in children now number 256, which represents just 0.06% of coronavirus deaths for all ages among the 43 states (along with New York City and Guam) reporting such data.

Among those jurisdictions, Texas (40), Arizona (27), and New York City (23) have reported the most deaths in children, while nine states and the District of Columbia have reported no deaths yet, the AAP and CHA noted.

The lowest rates can be found in Hawaii (1,040 per 100,000 children), Vermont (2,111 per 100,000), and Maine (2,394), while the highest rates were recorded in North Dakota (8,580), Tennessee (7,851), and Rhode Island (7,223), the AAP and CHA said.

The number of new child deaths, nine, stayed in single digits for a second consecutive week, although it was up from six deaths reported a week earlier. Total COVID-19–related deaths in children now number 256, which represents just 0.06% of coronavirus deaths for all ages among the 43 states (along with New York City and Guam) reporting such data.

Among those jurisdictions, Texas (40), Arizona (27), and New York City (23) have reported the most deaths in children, while nine states and the District of Columbia have reported no deaths yet, the AAP and CHA noted.

The number of new COVID-19 cases in children declined for the sixth consecutive week, but the drop was the smallest yet, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

New child cases in the United States totaled 64,264 for the week of Feb. 19-25, down from 70,640 the week before. That drop of almost 6,400 cases, or 9.0%, falls short of the declines recorded in any the previous 5 weeks, which ranged from 18,000 to 46,000 cases and 15.3% to 28.7%, based on data from the heath departments of 49 states (excluding New York), as well as the District of Columbia, New York City, Puerto Rico, and Guam.

The total number of children infected with SARS-CoV-2 is up to almost 3.17 million, which represents 13.1% of cases among all age groups. That cumulative proportion was unchanged from the previous week, which has occurred only three other times over the course of the pandemic, the AAP and CHA said in their weekly COVID-19 report.

What happened to Hasan Gokal, MD, should stick painfully in the craws of all physicians. It should serve as a call to action, because Dr. Gokal is sitting at home today without a job and under threat of further legal action while we continue about our day.

Dr. Gokal’s “crime” is that he vaccinated 10 strangers and acquaintances with soon-to-expire doses of the Moderna COVID-19 vaccine. He drove to the homes of some in the dark of night and injected others on his Sugar Land, Texas, lawn. He spent hours in a frantic search for willing recipients to beat the expiration clock. With minutes to spare, he gave the last dose to his at-risk wife, who has symptomatic pulmonary sarcoidosis, but whose age meant she did not fall into a vaccine priority tier.

According to the New York Times, Dr. Gokal’s wife was hesitant, afraid he might get into trouble. But why would she be hesitant? He wasn’t doing anything immoral. Perhaps she knew how far physicians have fallen and how bitterly they both could suffer.

In Barren County, Ky., where I live, a state of emergency was declared by our judge executive because of inclement weather. This directive allows our emergency management to “waive procedures and formalities otherwise required by the law.” It’s too bad that the same courtesy was not afforded to Dr. Gokal in Texas. It’s a shame that ice and snow didn’t drive his actions. Perhaps that would have protected him against the harsh criticism. Rather, it was his oath to patients and dedication to his fellow humans that motivated him, and for that, he was made to suffer.

Dr. Gokal was right to think that pouring the last 10 vaccine doses down the toilet would be an egregious act. But he was wrong in thinking his decision to find takers for the vaccine would be viewed as expedient. Instead, he was accused of graft and even nepotism. And there is the rub. That he was fired and charged with the theft of $137 worth of vaccines says everything about how physicians are treated in the year 2021. Dr. Gokal’s lawyer says the charge carried a maximum penalty of 1 year in prison and a fine of nearly $4,000.

Thank God a sage judge threw out the case and “rebuked” the office of District Attorney Kim Ogg. That hasn’t stopped her from threatening to bring the case to a grand jury. That threat invites anyone faced with the same scenario to flush the extra vaccine doses into the septic system. It encourages us to choose the toilet handle to avoid a mug shot.

And we can’t ignore the racial slant to this story. The Times reported that Dr. Gokal asked the officials, “Are you suggesting that there were too many Indian names in this group?”

“Exactly” was the answer. Let that sink in.

None of this would have happened 20 years ago. Back then, no one would have questioned the wisdom a physician gains from all our years of training and residency. In an age when anyone who conducts an office visit is now called “doctor,” respect for the letters “MD” has been leveled. We physicians have lost our autonomy and been cowed into submission.

But whatever his profession, Hasan Gokal was fired for being a good human. Today, the sun rose on 10 individuals who now enjoy better protection against a deadly pandemic. They include a bed-bound nonagenarian. A woman in her 80s with dementia. A mother with a child who uses a ventilator. All now have antibodies against SARS-CoV2 because of the tireless actions of Dr. Gokal.

Yet Dr. Gokal’s future is uncertain. Will we help him, or will we leave him to the wolves? In an email exchange with his lawyer’s office, I learned that Dr. Gokal has received offers of employment but is unable to entertain them because the actions by the Harris County District Attorney triggered an automatic review by the Texas Medical Board. A GoFundMe page was launched, but an appreciative Dr. Gokal stated publicly that he’d rather the money go to a needy charity.

 In the last paragraph of the Times article, Dr. Gokal asks, “How can I take it back?” referencing stories about “the Pakistani doctor in Houston who stole all those vaccines.”

Let’s help him take back his story. In helping him, perhaps we can take back a little control. We could start with letters of support that could be mailed to his lawyer, Paul Doyle, Esq., of Houston, or tweet, respectfully of course, to the district attorney @Kimoggforda.

We can also let the Harris County Public Health Department in Houston know what we think of their actions.

On Martin Luther King Day, Kim Ogg, the district attorney who charged Dr. Gokal, tweeted MLK’s famous quote: “Injustice anywhere is a threat to justice everywhere.”

Let that motivate us to action.

Among individuals with asthma and allergies who use cannabis, more than half said they aren’t willing to discuss their use of cannabis with their doctor and their doctor doesn’t ask, according to recent research at the annual meeting of the American Academy of Allergy, Asthma, and Immunology, held virtually this year.

In an online survey of respondents with asthma and allergies in the Allergy & Asthma Network, 88 of 489 (18.0%) reported cannabis use. Of these respondents, 37.5% said they wanted to discuss their cannabis use with their doctor, 51.1% said they would not want to, and 11.4% reported they were unsure. In addition, 40.9% of respondents said their doctor inquired about cannabis use, while 51.1% said their doctor did not bring up cannabis use at all, either through a verbal discussion or on an intake form.

To date, there has not been much research on use of cannabis among patients with allergies and asthma, Joanna S. Zeiger, MS, PhD, of the Canna Research Foundation in Boulder, Colo., said in her presentation. “This is a group with whom route of administration could have broad adverse effects. Smoking or vaping cannabis in this population could lead to increased symptoms of cough and wheeze, as well as increased use of asthma medications and exacerbations of their disease.”

Dr. Zeiger and colleagues recruited 489 respondents for the AAN Pain, Exercise, and Cannabis Experience Survey study through social media channels between May 2020 and September 2020. In the survey, the researchers asked questions about the nature of the respondent’s cannabis use (medical, recreational, or both), the types of cannabinoids used (tetrahydrocannabinol [THC], cannabidiol [CBD], or both), the route of administration (capsule, edible, oil/tincture, smoke, spray, topical, or vaporizer), and subjective effects. Most of the respondents reported using both THC and CBD, with smoking, edibles, and vaping being the most comment route of administration.

Of the 88 respondents who said they currently used cannabis, 60.2% were aged less than 50 years, 72.4% were women, and 71.6% were White. A majority of respondents had been using cannabis for 3 or more years (54.5%) , used it less than one time per day (60.2%), and used it for pain (68.2%). Current asthma was reported in 51 respondents (58.0%), and 39.2% had uncontrolled asthma. Half of those respondents with uncontrolled asthma reported smoking cannabis, and 25.0% reported coughing because of cannabis. Both THC and CBD were used by 47.7% of respondents; 33% reported THC use alone, while 19.3% used CBD alone.

Reported effects of cannabis use

The most common positive effects of using cannabis reported among respondents were that it helped with sleep (66 respondents), calmed them down (60 respondents), reduced pain (60 respondents), or decreased anxiety (59 respondents). Many respondents who reported positive effects were using both THC and CBD. For example, respondents who reported using cannabinoids for calming, 46.7% reported using both, compared with 36.7% who used THC only and 16.7% who used CBD only. Among respondents who reported that cannabis helped them sleep, 51.5% used both THC and CBD.

Regarding adverse effects, there were no significant differences based on use of THC or CBD, but 31.9% of respondents who said they smoked cannabis and 4.9% of respondents who used cannabis through a route of administration that wasn’t smoking reported they coughed with their cannabis use (P < .001). No respondents reported anaphyalaxis, although, among individuals who did not use cannabis, 2.5% reported a cannabis allergy.
 

‘Cannabis allergy is real’

Commenting on the research, Gordon L. Sussman MD, allergist, clinical immunologist, and clinical professor of medicine at the University of Toronto, said the survey is a thorough questionnaire that is likely representative of attitudes about cannabis in the United States and countries where cannabis is not broadly legalized.

Cannabis allergy, however, is not uncommon, and “is something that people should be aware of,” he said. “Cannabis IgE allergy is real, is probably fairly common, and is something that [clinicians] should be asking about routinely.”

One limitation of the research was not knowing the number of people who declined to answer the survey, as there may be a bias in the results toward people who want to answer the questions, compared with those who did not want to answer. “When you do a survey, only a certain number of people are going to answer, and [you also want input from] people that don’t answer,” Dr. Sussman said.

Dr. Sussman acknowledged it can be difficult to get patients to admit cannabis use, even in countries like Canada where it is legal. Surveys like the one administered by Dr. Zeiger and colleagues are “the first step” to getting updated assessments of cannabis attitudes and recommendations. “The next step is doing an international survey, so you get different countries’ viewpoints and perspectives,” he said.

This study was supported by the Allergy & Asthma Network and the Canna Research Foundation. Three authors are affiliated with the Canna Research Foundation. Dr. Sussman reported no financial conflicts of interest. Dr. Sussman participates in the International Cannabis Allergy KAP Collaboration, a group founded by one of the coauthors, William Silvers, MD, but Dr. Sussman was not involved with this study.

Dr. Sussman acknowledged it can be difficult to get patients to admit cannabis use, even in countries like Canada where it is legal. Surveys like the one administered by Dr. Zeiger and colleagues are “the first step” to getting updated assessments of cannabis attitudes and recommendations. “The next step is doing an international survey, so you get different countries’ viewpoints and perspectives,” he said.

This study was supported by the Allergy & Asthma Network and the Canna Research Foundation. Three authors are affiliated with the Canna Research Foundation. Dr. Sussman reported no financial conflicts of interest. Dr. Sussman participates in the International Cannabis Allergy KAP Collaboration, a group founded by one of the coauthors, William Silvers, MD, but Dr. Sussman was not involved with this study.
