Nonstimulants: A better option for ADHD?
.
Investigators studied patients who started out taking atomoxetine and, after a washout period, initiated treatment with viloxazine. Participants’ ADHD symptoms were assessed prior to initiation of each treatment and after 4 weeks.
Children and adults showed significantly larger improvement in inattentiveness and hyperactivity/impulsivity when taking viloxazine vs. atomoxetine, with almost all patients preferring the former to the latter, according to results of the study.
In addition, close to one half of the study participants were taking a prior stimulant, and 85% were able to taper off stimulant treatment. Viloxazine’s effects were more rapid than were those of atomoxetine.
“It is timely to have a rapidly acting, and highly effective nonstimulant option across the full spectrum of ADHD symptoms, for both children and adults, in light of recent stimulant shortages and the new [Food and Drug Administration] boxed warnings regarding increased mortality associated with overuse of stimulants” study investigator Maxwell Z. Price, a medical student at Hackensack Meridian School of Medicine, Nutley, N.J., said in an interview.
Nonstimulant treatment options
Study coauthor Richard L. Price, MD, noted that the study was conducted to find a more acceptable alternative to psychostimulant treatments for ADHD, which are currently considered the “gold standard.”
Although they are effective, said Dr. Price, they are fraught with adverse effects, including appetite suppression, insomnia, exacerbation of mood disorders, anxiety, tics, or misuse.
Atomoxetine, a nonstimulant option, has been around for a few decades and is often used in combination with a stimulant medication. However, he said, the drug has a mild effect, requires frequent dosage adjustment, takes a long time to work, and people have “soured” on its utility, Dr. Price added.
Like atomoxetine, viloxazine is a selective norepinephrine inhibitor that has been used an antidepressant in Europe for 30 years. It was recently reformulated as an extended-release medication and approved by the FDA for pediatric and adult ADHD.
However, unlike atomoxetine, viloxazine is associated with increased prefrontal cortex 5-hydroxytrytamine, norepinephrine, and dopamine levels in vivo.
There have been no head-to-head trials comparing the two agents. However, even in head-to-head ADHD medication trials, the agents that are under investigation are typically compared in matched patients. The current investigators wanted to compare the two agents in the same patients whose insurers mandate a trial of generic atomoxetine prior to covering branded viloxazine.
“We wanted to find out whether patients taking atomoxetine for ADHD combined type would experience improvement in ADHD symptoms following voluntary, open-label switch to viloxazine,” said Dr. Price.
The researchers studied 50 patients who presented with ADHD combined type and had no other psychiatric, medical, or substance-related comorbidities or prior exposure to atomoxetine or viloxazine.
The study included 35 children (mean age, 11.9 ± 2.9 years; 94.3% male) and 15 adults (mean age, 29.3 ± 9.0 years; 73.3% male). Of these, 42.9% and 73.3%, respectively, were taking concurrent stimulants.
Patients received mean doses of atomoxetine once daily followed by viloxazine once daily after a 5-day washout period between the two drugs. Participants were seen weekly for titration and monitoring.
At baseline, the pediatric ADHD–Rating Scale 5 (ADHD-RS-5) and the Adult Investigator Symptoms Rating Scale (AISRS) were completed, then again after 4 weeks of treatment with atomoxetine (or upon earlier response or discontinuation due to side effects, whichever came first), and 5 days after discontinuing atomoxetine, which “reestablished the baseline score.” The same protocol was then repeated with viloxazine.
‘Paradigm shift’
At baseline, the total ADHD-RS-5 mean score was 40.3 ± 10.3. Improvements at 4 weeks were greater in viloxazine vs atomoxetine, with scores of 13.9 ± 10.2 vs 33.1 ± 12.1, respectively (t = -10.12, P < .00001). In inattention and hyperactivity/impulsivity, the t values were –8.57 and –9.87, respectively (both P values < .0001).
Similarly, from the baseline total, AISRS mean score of 37.3 ± 11.8, improvements were greater on viloxazine vs. atomoxetine, with scores of 11.9 ± 9.4 vs. 28.8 ± 14.9, respectively (t = −4.18, P = .0009 overall; for inattention, t = −3.50, P > .004 and for hyperactivity/impulsivity, t = 3.90, P > .002).
By 2 weeks, 86% of patients taking viloxazine reported a positive response vs. 14% when taking atomoxetine.
Side effects were lower in viloxazine vs. atomoxetine, with 36% of patients discontinuing treatment with atomoxetine because of side effects that included gastrointestinal upset, irritability, fatigue, and insomnia vs. 4% who discontinued viloxazine because of fatigue.
Almost all participants (96%) preferred viloxazine over atomoxetine and 85% were able to taper off stimulant treatment following stabilization on viloxazine.
“These were not small differences,” said Dr. Richard L. Price. “These were clinically and statistically meaningful differences.”
The findings could represent “a paradigm shift for the field” because “we always think of starting ADHD treatment with stimulants, but perhaps treatment with viloxazine could help patients to avoid stimulants entirely,” he suggested.
Real-world study
Commenting for this article, Greg Mattingly, MD, associate clinical professor, Washington University, St. Louis, called it “a timely addition to the clinical literature where for the first time ever we have two nonstimulant options approved for adults with ADHD.”
This real-world clinic study “yields many answers,” said Dr. Mattingly, president-elect of the American Professional Society of ADHD and Related Disorders (APSARD), who was not involved with the study.
“Simply put, this real-world study of 50 clinic patients found that viloxazine ER had faster onset, was significantly more effective, and was preferred by 96% of patients as compared to atomoxetine,” he said.
“Another intriguing part of the study that will be of high interest to both patients and providers was that, of those initially treated concurrently with stimulant and viloxazine ER, 85% were able to discontinue their stimulant medication,” Dr. Mattingly added.
This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors. The open access fee was funded by the investigators. Dr. Maxwell Z. Price certifies that there is no conflict of interest with any financial organization regarding the material discussed in the manuscript. Dr. Richard L. Price has received honoraria from AbbVie, Alkermes, Idorsia, Intra-Cellular Therapies, Janssen, Jazz, Lundbeck, Neuronetics, Otsuka, and Supernus. Dr. Mattingly reports financial disclosures with various pharmaceutical companies, which are listed in full in the paper.

FROM CNS DRUGS
FDA approves cantharidin for molluscum contagiosum
On July 21, 2023, .
The product is a drug-device combination that contains a formulation of cantharidin solution (0.7%), delivered topically via a single-use applicator, which allows for precise dosing and targeted administration. According to a press release from Verrica Pharmaceuticals, cantharidin is expected to be available by September 2023 and should be administered only by a trained health care professional; it is not for use in the home.
The approval of the product, also known as VP-102, is based on results from two identical multicenter phase 3 randomized, double-blind, placebo-controlled trials that evaluated the drug’s safety and efficacy in patients 2 years of age and older diagnosed with molluscum: Cantharidin Application in Molluscum Patients-1 (CAMP-1) and CAMP-2. Patients in both trials met the primary endpoint of complete clearance of all treatable molluscum lesions. Specifically, 46% of CAMP-1 participants treated with VP-102 achieved complete clearance of molluscum lesions compared with 18% of participants in the vehicle group (P < .0001), while 54% of CAMP-2 participants treated with VP-102 achieved complete clearance of molluscum lesions compared with 13% of participants in the vehicle group (P < .0001).
A post hoc analysis of both trials found that complete clearance of all lesions was significantly higher in the VP-102 group than vehicle across all body regions. It also found that there were no serious adverse reactions reported in the trials. Adverse reactions were mostly mild to moderate and included application site vesicles, erythema, pain, dryness, scab, discoloration, pruritus, and edema.
The product will be marketed as Ycanth.
In March of 2023, the FDA accepted a new drug application for another treatment for molluscum contagiosum, berdazimer gel 10.3%. That product is being developed by Novan.

Study examines pediatric skin biopsy trends at a tertiary care center
.
In addition, fewer biopsies were performed in the first 3 years of the global COVID-19 pandemic than in the previous 3 years.
These findings from a retrospective analysis were presented during a poster session at the annual meeting of the Society for Pediatric Dermatology. The analysis set out to evaluate which patients required biopsy, which skin conditions were sampled, and if practice patterns changed following the start of the COVID-19 pandemic.
“The work is important because very few pediatric patients, relative to adult patients seen in dermatology clinics, have a biopsy done,” Kelly M. Cordoro, MD, one of the study authors, told this news organization.
“Approximately 1%-4% of pediatric patients visiting a dermatology clinic will have a biopsy done as compared to 30%-50% of adult patients. Understanding what is being biopsied in children sheds light on the medical decision-making required to decide when a biopsy is necessary,” said Dr. Cordoro, chief of pediatric dermatology at UCSF.
For the study, the researchers retrospectively reviewed 1,196 biopsy specimens from 1,080 unique patients that were performed by pediatric dermatologists at UCSF from 2017 to 2022. Half of the patients were female, their mean age was 11.5 years, and they ranged in age from 1 day to 61 years. Nearly half of biopsies (47%) were performed in patients aged 12-18 years and one-quarter (25.6%) were performed in those aged 6-11 years. In the remaining biopsies, 6.6% came from patients younger than 1 year, 5.8% of those aged 1-2 years, 7.3% from those aged 3-5 years, and 3.9% each in those aged 19-21 years and in those older than 21 years.
The five most common biopsy results were compound nevus (99 biopsies), pyogenic granuloma (96), spongiotic dermatitis (57), intradermal nevus (53), and pilomatricoma (40).
The researchers identified 30 malignant diagnoses in 28 unique patients, most commonly mycosis fungoides (in 16 patients with a median age of 12.5 years), basal cell carcinoma (in 5 patients with a median age of 9 years), and dermatofibrosarcoma protuberans (in 4 patients with a median age of 2 years).
There was no significant sex-based difference in the number of biopsies performed at a given age (P = .47), but Dr. Cordoro and colleagues noted a statistically significant decrease in the number of biopsies during the pandemic compared with the 3 years prior to the pandemic (P = .04).
“There was a slight uptick in 2022, although it remains to be seen whether this trend will continue,” they wrote in their abstract. “While the most common diagnoses in the years leading up to – versus following the start of the pandemic – were similar, there was one clear outlier. The histopathologic diagnosis of pernio spiked in 2020, reflecting the ‘COVID toes’ phenomenon”.
In an interview, Dr. Cordoro said that growths and rashes in children of all ages can, and should, be biopsied, but special considerations are necessary depending on the patient’s age and context.
“Our data showed that neoplastic conditions were biopsied more often than inflammatory conditions, with an emphasis on lesions that required removal (such as pyogenic granuloma), raised concerns for atypia (nevi), or had implications for systemic management (such as Langerhans cell histiocytosis and graft-versus-host disease). Importantly, cutaneous malignancies in children are rare but do occur, and a high index of suspicion is required when approaching any child with a complex neoplasm or rash.”
Dr. Cordoro characterized the medical decision making and rationale for biopsying skin lesions and rashes in children as “a complex process that involves weighing the risks of the biopsy itself against the benefit of the information it will provide; shared decision-making with the caregivers, the patient (if age-appropriate), and other members of the health care team; age of the child and clinical context; and whether the biopsy can be done at the bedside or requires sedation.”
Based on the study results, Dr. Cordoro said, the rationale to proceed with a biopsy boils down to three main goals: To make or confirm a diagnosis, to make decisions about management, and/or the biopsy itself is therapeutic.
UCSF dermatopathology fellow Suzanne W. Birmingham, MD, performed the study in collaboration with Dr. Cordoro and UCSF dermatopathologist Thaddeus W. Mully, MD. Additional analyses of this data set are in progress. The researchers reported having no relevant financial disclosures.

The researchers identified 30 malignant diagnoses in 28 unique patients, most commonly mycosis fungoides (in 16 patients with a median age of 12.5 years), basal cell carcinoma (in 5 patients with a median age of 9 years), and dermatofibrosarcoma protuberans (in 4 patients with a median age of 2 years).
There was no significant sex-based difference in the number of biopsies performed at a given age (P = .47), but Dr. Cordoro and colleagues noted a statistically significant decrease in the number of biopsies during the pandemic compared with the 3 years prior to the pandemic (P = .04).
“There was a slight uptick in 2022, although it remains to be seen whether this trend will continue,” they wrote in their abstract. “While the most common diagnoses in the years leading up to – versus following the start of the pandemic – were similar, there was one clear outlier. The histopathologic diagnosis of pernio spiked in 2020, reflecting the ‘COVID toes’ phenomenon”.
In an interview, Dr. Cordoro said that growths and rashes in children of all ages can, and should, be biopsied, but special considerations are necessary depending on the patient’s age and context.
“Our data showed that neoplastic conditions were biopsied more often than inflammatory conditions, with an emphasis on lesions that required removal (such as pyogenic granuloma), raised concerns for atypia (nevi), or had implications for systemic management (such as Langerhans cell histiocytosis and graft-versus-host disease). Importantly, cutaneous malignancies in children are rare but do occur, and a high index of suspicion is required when approaching any child with a complex neoplasm or rash.”
Dr. Cordoro characterized the medical decision making and rationale for biopsying skin lesions and rashes in children as “a complex process that involves weighing the risks of the biopsy itself against the benefit of the information it will provide; shared decision-making with the caregivers, the patient (if age-appropriate), and other members of the health care team; age of the child and clinical context; and whether the biopsy can be done at the bedside or requires sedation.”
Based on the study results, Dr. Cordoro said, the rationale to proceed with a biopsy boils down to three main goals: To make or confirm a diagnosis, to make decisions about management, and/or the biopsy itself is therapeutic.
UCSF dermatopathology fellow Suzanne W. Birmingham, MD, performed the study in collaboration with Dr. Cordoro and UCSF dermatopathologist Thaddeus W. Mully, MD. Additional analyses of this data set are in progress. The researchers reported having no relevant financial disclosures.

In addition, fewer biopsies were performed in the first 3 years of the global COVID-19 pandemic than in the previous 3 years.
These findings from a retrospective analysis were presented during a poster session at the annual meeting of the Society for Pediatric Dermatology. The analysis set out to evaluate which patients required biopsy, which skin conditions were sampled, and if practice patterns changed following the start of the COVID-19 pandemic.
“The work is important because very few pediatric patients, relative to adult patients seen in dermatology clinics, have a biopsy done,” Kelly M. Cordoro, MD, one of the study authors, told this news organization.
“Approximately 1%-4% of pediatric patients visiting a dermatology clinic will have a biopsy done as compared to 30%-50% of adult patients. Understanding what is being biopsied in children sheds light on the medical decision-making required to decide when a biopsy is necessary,” said Dr. Cordoro, chief of pediatric dermatology at UCSF.
For the study, the researchers retrospectively reviewed 1,196 biopsy specimens from 1,080 unique patients that were performed by pediatric dermatologists at UCSF from 2017 to 2022. Half of the patients were female, their mean age was 11.5 years, and they ranged in age from 1 day to 61 years. Nearly half of biopsies (47%) were performed in patients aged 12-18 years and one-quarter (25.6%) were performed in those aged 6-11 years. In the remaining biopsies, 6.6% came from patients younger than 1 year, 5.8% of those aged 1-2 years, 7.3% from those aged 3-5 years, and 3.9% each in those aged 19-21 years and in those older than 21 years.

What makes teens choose to use sunscreen?
a cornerstone of skin cancer prevention, according to results from a systematic review.
“We know that skin cancer is one of the most common malignancies in the world, and sun protection methods such as sunscreen make it highly preventable,” first author Carly R. Stevens, a student at Tulane University, New Orleans, said in an interview. “This study demonstrates the adolescent populations that are most vulnerable to sun damage and how we can help mitigate their risk of developing skin cancer through education methods, such as Sun Protection Outreach Teaching by Students.”
Ms. Stevens and coauthors presented the findings during a poster session at the annual meeting of the Society for Pediatric Dermatology.
To investigate predictors of sunscreen use among high school students, they searched PubMed, Embase, and Web of Science using the terms (“sunscreen” or “SPF” or “sun protection”) and (“high school” or “teen” or “teenager” or “adolescent”) and limited the analysis to English studies reporting data on sunscreen use in U.S. high school students up to November 2021.
A total of 20 studies were included in the final review. The study populations ranged in number from 208 to 24,645. Of 11 studies that examined gender, all showed increased sunscreen use in females compared with males. Of five studies that examined age, all showed increased sunscreen use in younger adolescents, compared with their older counterparts.
Of four studies that examined the role of ethnicity on sunscreen use, White students were more likely to use sunscreen, compared with their peers of other ethnicities. “This may be due to perceived sun sensitivity, as [these four studies] also showed increased sunscreen use in populations that believed were more susceptible to sun damage,” the researchers wrote in their abstract.
In other findings, two studies that examined perceived self-efficacy concluded that higher levels of sunscreen use correlated with higher self-efficacy, while four studies concluded that high school students were more likely to use sunscreen if their parents encouraged them the wear it or if the parent used it themselves.
“With 40%-50% of ultraviolet damage being done before the age of 20, it’s crucial that we find ways to educate adolescents on the importance of sunscreen use and target those populations who were found to rarely use sunscreen in our study,” Ms. Stevens said.
In one outreach program, Sun Protection Outreach Teaching by Students (SPOTS), medical students visit middle and high schools to educate them about the importance of practicing sun protection. The program began as a collaboration between Saint Louis University and Washington University in St. Louis, but has expanded nationwide. Ms. Stevens described SPOTS as “a great way for medical students to present the information to middle and high school students in a way that is engaging and interactive.”

When treating AD in children, experts consider adherence, other aspects of treatment
ASHEVILLE, N.C. – according to a three-member expert panel mulling over strategies at the annual meeting of the Society for Pediatric Dermatology.
In introductory remarks, the three panelists briefly addressed different aspects for controlling AD, including drugs in the pipeline, the potential value of alternative therapies, and whom to blame when compliance is poor.
But panel discussion following these presentations provided an opportunity for audience engagement on practical strategies for improving AD control.
In her formal remarks prior to the panel discussion, Amy S. Paller, MD, professor of dermatology and pediatrics and chair of dermatology, Northwestern University, Chicago, and a pediatric dermatologist at the Lurie Children’s Hospital of Chicago, described emerging AD treatments. This included an update on the status of the interleukin-13 (IL-13) inhibitors tralokinumab (Adbry), which was approved by the FDA for treating AD in adults in December 2021, and lebrikizumab, which is thought likely to be soon approved in the United States on the basis of two recently published phase 3 trials.
Along with dupilumab (Dupixent) for moderate-to-severe AD in children who do not respond to optimized use of topical therapies, these new biologics appear likely to further expand choices for AD control for adults (and for kids with AD too, if eventually licensed in children), according to the data from the phase 3 studies.
During a panel discussion that followed, Stephen Gellis, MD, pediatric dermatologist and former chief of pediatric dermatology at Boston Children’s Hospital and Harvard Medical School, raised the point of optimizing tried and true topical therapies before using systemic agents. He noted that parents sometimes pressure clinicians to use a biologic – and that moving too quickly to the latest and most expensive drugs may not be necessary.
Dr. Paller acknowledged that she, like many pediatric dermatologists, employed immunosuppressants as her drugs of choice for many years – commonly starting with a few months of cyclosporine before transitioning to methotrexate, which has a delayed onset of action. In fact, she still uses this regimen in some children.
However, she now prefers dupilumab, which is the first biologic available for children in the United States with an AD indication in children as young as 6 months. She said dupilumab has fewer potential risks than cyclosporine, and it offers clinically meaningful improvement in most children. She noted that current guidelines discourage the use of systemic corticosteroids for AD in children, given their potential toxicity.
She strongly agreed with Dr. Gellis that clinicians should resist pressure to use any systemic agent if children are responding well to topical medications. In her own practice, Dr. Paller moves to systemic medications only after ensuring that there has been adherence to appropriate therapy and that there is not another diagnosis that might explain the recalcitrance to topical agents.
When a systemic medication is considered the next step, Dr. Paller reminded the audience of the importance of presenting the benefits and risks of all the options for AD control, which could include dupilumab and immunosuppressants as initial systemic therapy.
“Many parents choose biologic treatment first, given its lack of requirement for blood monitoring and faster action than methotrexate,” Dr. Paller noted.
Nevertheless, “biologics are much more costly than immunosuppressants, require an injection – which is stressful for the child and the parents – and may not be accessible for our patients,” Dr. Paller said. Cyclosporine and methotrexate are effective and are often the best options for moderate to severe disease in areas of the world where dupilumab is not available, but Dr. Paller most commonly uses these therapies only when reimbursement for dupilumab cannot be secured, injection is not an option, or when dupilumab is not sufficiently effective and tolerated.
Providing different perspectives, the two other panelists discussing the treatment of pediatric AD also saw a role for ensuring that topical agents are not offering adequate AD control before turning to the latest and most sophisticated therapies for AD.
For meeting parent expectations when children are improving slowly on topical therapies, Peter A. Lio, MD, director of the Chicago Integrative Eczema Center and clinical assistant professor of dermatology and pediatrics at Northwestern University, suggested that integrative medicine might be helpful.
For parents not fully comfortable with standard pharmacologic agents, Dr. Lio said there is evidence to support some of the complementary approaches, and these can be reassuring to parents with an interest in alternative medicines.
In Western medicine, it is common to hear terms like “attack,” “kill,” and “suppress,” disease, but alternative therapies are generally coupled with terms like “restore,” “strengthen,” and “tonify,” he said. “Who doesn’t want to be tonified?” he asked, noting that there are many sources of data suggesting that the number of patients seeking alternative medicine is “huge.” The alternative medicines are not generally taught in medical school and remain widely ignored in typical practice, but “our patients are interested even if we are not.”
Yet, there are data to support benefit from some of these alternative therapies, providing a win-win situation for patients who derive satisfaction from nontraditional therapies alone or combined with established pharmaceutical treatments.
Of these, Dr. Lio said there is support for the use of hempseed oil as a moisturizing agent and a strategy for improving barrier function in the skin of patients with AD. In a controlled crossover study, 2 teaspoons per day of dietary hempseed oil, a product that can be purchased in some grocery stores, was associated with significant reductions in skin dryness, itchiness, and use of topical medications relative to the same amount of olive oil, he noted.
Other examples include a compress made with black tea that was associated with an anti-inflammatory effect when followed by a moisturizer, a published study asserts. Although this was a trial in adults with facial dermatitis, Dr. Lio suggested that the same anti-inflammatory effect would be anticipated for other skin conditions, including AD in children.
As a third example, Dr. Lio said topical indigo, a traditional Chinese medicine used for a variety of dermatologic conditions, including psoriasis, has also demonstrated efficacy in a randomized trial, compared with vehicle for mild to severe AD.
Complementary medicines are not for everyone, but they may have a role when managing the expectations of parents who are not fully satisfied or express concern about regimens limited to mainstream therapies alone, according to Dr. Lio. In diseases that are not curable, such as AD, he thinks this is a strategy with potential for benefit and is reassuring to patients.
Another way to avoid moving to riskier or more expensive drugs quickly is to assure patients use the drugs that were prescribed first, according to Steven R. Feldman, MD, PhD, professor of dermatology, Wake Forest University, Winston-Salem, N.C.
Dr. Feldman believes that failure to adhere to therapy is basically the fault of the medical care system, not the patient. He made an analogy to a successful piano teacher, who provides a child with sheet music and then sees the child once a week to track progress. He juxtaposed this piano teacher to one who gives the child sheet music and tells the child to come back in 10 weeks for the recital. It is not hard to guess which approach would be more effective.
“Typically, doctors are worse than that second teacher,” he said. “Doctors are like a piano teacher that does not give you the sheet music but says, ‘Here is a prescription for some sheet music. Take this prescription to the sheet music store. I have no idea how much it will cost or whether your insurance will pay for it. But once you fill this prescription for sheet music, I want you to practice this every day,’ ” he said, adding, “Practicing this sheet music may cause rashes, diarrhea, or serious infection. When the patient next comes in 10-12 weeks later and is not better, the doctor says, ‘I will give you a harder piece of sheet music and maybe two or three other instruments to practice at the same time,’ ” said Dr. Feldman, expressing why the way clinicians practice might explain much of the poor adherence problem.
This largely explains why patients with AD do not immediately respond to the therapies doctors prescribe, Dr. Feldman implied, reiterating the theme that emerged from the AD panel: Better and more options are needed for AD of the most severe types, but better management, not better drugs, is typically what is needed for most patients.
Dr. Feldman, Dr. Lio, and Dr. Paller have financial relationships with more than 30 pharmaceutical and cosmetic companies, some of which manufacture therapies for atopic dermatitis.

This included an update on the status of the interleukin-13 (IL-13) inhibitors tralokinumab (Adbry), which was approved by the FDA for treating AD in adults in December 2021, and lebrikizumab, which is thought likely to be soon approved in the United States on the basis of two recently published phase 3 trials.
Along with dupilumab (Dupixent) for moderate-to-severe AD in children who do not respond to optimized use of topical therapies, these new biologics appear likely to further expand choices for AD control for adults (and for kids with AD too, if eventually licensed in children), according to the data from the phase 3 studies.
During a panel discussion that followed, Stephen Gellis, MD, pediatric dermatologist and former chief of pediatric dermatology at Boston Children’s Hospital and Harvard Medical School, raised the point of optimizing tried and true topical therapies before using systemic agents. He noted that parents sometimes pressure clinicians to use a biologic – and that moving too quickly to the latest and most expensive drugs may not be necessary.
Dr. Paller acknowledged that she, like many pediatric dermatologists, employed immunosuppressants as her drugs of choice for many years – commonly starting with a few months of cyclosporine before transitioning to methotrexate, which has a delayed onset of action. In fact, she still uses this regimen in some children.
However, she now prefers dupilumab, which is the first biologic available for children in the United States with an AD indication in children as young as 6 months. She said dupilumab has fewer potential risks than cyclosporine, and it offers clinically meaningful improvement in most children. She noted that current guidelines discourage the use of systemic corticosteroids for AD in children, given their potential toxicity.
She strongly agreed with Dr. Gellis that clinicians should resist pressure to use any systemic agent if children are responding well to topical medications. In her own practice, Dr. Paller moves to systemic medications only after ensuring that there has been adherence to appropriate therapy and that there is not another diagnosis that might explain the recalcitrance to topical agents.
When a systemic medication is considered the next step, Dr. Paller reminded the audience of the importance of presenting the benefits and risks of all the options for AD control, which could include dupilumab and immunosuppressants as initial systemic therapy.
“Many parents choose biologic treatment first, given its lack of requirement for blood monitoring and faster action than methotrexate,” Dr. Paller noted.
Nevertheless, “biologics are much more costly than immunosuppressants, require an injection – which is stressful for the child and the parents – and may not be accessible for our patients,” Dr. Paller said. Cyclosporine and methotrexate are effective and are often the best options for moderate to severe disease in areas of the world where dupilumab is not available, but Dr. Paller most commonly uses these therapies only when reimbursement for dupilumab cannot be secured, injection is not an option, or when dupilumab is not sufficiently effective and tolerated.
Providing different perspectives, the two other panelists discussing the treatment of pediatric AD also saw a role for ensuring that topical agents are not offering adequate AD control before turning to the latest and most sophisticated therapies for AD.
For meeting parent expectations when children are improving slowly on topical therapies, Peter A. Lio, MD, director of the Chicago Integrative Eczema Center and clinical assistant professor of dermatology and pediatrics at Northwestern University, suggested that integrative medicine might be helpful.
For parents not fully comfortable with standard pharmacologic agents, Dr. Lio said there is evidence to support some of the complementary approaches, and these can be reassuring to parents with an interest in alternative medicines.
In Western medicine, it is common to hear terms like “attack,” “kill,” and “suppress,” disease, but alternative therapies are generally coupled with terms like “restore,” “strengthen,” and “tonify,” he said. “Who doesn’t want to be tonified?” he asked, noting that there are many sources of data suggesting that the number of patients seeking alternative medicine is “huge.” The alternative medicines are not generally taught in medical school and remain widely ignored in typical practice, but “our patients are interested even if we are not.”
Yet, there are data to support benefit from some of these alternative therapies, providing a win-win situation for patients who derive satisfaction from nontraditional therapies alone or combined with established pharmaceutical treatments.
Of these, Dr. Lio said there is support for the use of hempseed oil as a moisturizing agent and a strategy for improving barrier function in the skin of patients with AD. In a controlled crossover study, 2 teaspoons per day of dietary hempseed oil, a product that can be purchased in some grocery stores, was associated with significant reductions in skin dryness, itchiness, and use of topical medications relative to the same amount of olive oil, he noted.
Other examples include a compress made with black tea that was associated with an anti-inflammatory effect when followed by a moisturizer, a published study asserts. Although this was a trial in adults with facial dermatitis, Dr. Lio suggested that the same anti-inflammatory effect would be anticipated for other skin conditions, including AD in children.
As a third example, Dr. Lio said topical indigo, a traditional Chinese medicine used for a variety of dermatologic conditions, including psoriasis, has also demonstrated efficacy in a randomized trial, compared with vehicle for mild to severe AD.
Complementary medicines are not for everyone, but they may have a role when managing the expectations of parents who are not fully satisfied or express concern about regimens limited to mainstream therapies alone, according to Dr. Lio. In diseases that are not curable, such as AD, he thinks this is a strategy with potential for benefit and is reassuring to patients.
Another way to avoid moving to riskier or more expensive drugs quickly is to assure patients use the drugs that were prescribed first, according to Steven R. Feldman, MD, PhD, professor of dermatology, Wake Forest University, Winston-Salem, N.C.
Dr. Feldman believes that failure to adhere to therapy is basically the fault of the medical care system, not the patient. He made an analogy to a successful piano teacher, who provides a child with sheet music and then sees the child once a week to track progress. He juxtaposed this piano teacher to one who gives the child sheet music and tells the child to come back in 10 weeks for the recital. It is not hard to guess which approach would be more effective.
“Typically, doctors are worse than that second teacher,” he said. “Doctors are like a piano teacher that does not give you the sheet music but says, ‘Here is a prescription for some sheet music. Take this prescription to the sheet music store. I have no idea how much it will cost or whether your insurance will pay for it. But once you fill this prescription for sheet music, I want you to practice this every day,’ ” he said, adding, “Practicing this sheet music may cause rashes, diarrhea, or serious infection. When the patient next comes in 10-12 weeks later and is not better, the doctor says, ‘I will give you a harder piece of sheet music and maybe two or three other instruments to practice at the same time,’ ” said Dr. Feldman, expressing why the way clinicians practice might explain much of the poor adherence problem.
This largely explains why patients with AD do not immediately respond to the therapies doctors prescribe, Dr. Feldman implied, reiterating the theme that emerged from the AD panel: Better and more options are needed for AD of the most severe types, but better management, not better drugs, is typically what is needed for most patients.
Dr. Feldman, Dr. Lio, and Dr. Paller have financial relationships with more than 30 pharmaceutical and cosmetic companies, some of which manufacture therapies for atopic dermatitis.

Ocular complications of dermatologic treatments: Advice from a pediatric ophthalmologist
ASHEVILLE, N.C. – The, according to one of several clinical messages from a pediatric ophthalmologist who spoke at the annual meeting of the Society for Pediatric Dermatology.
“There is a lot of steroid fear out there, which you can argue is actually harmful in itself, because not treating periorbital eczema is related to a lot of eye problems, including chronic discomfort and the eye rubbing that can cause corneal abrasions and keratoconus,” said Sara Grace, MD, a pediatric ophthalmologist who is on the clinical staff at Duke University, Durham, N.C. She maintains a practice at North Carolina Eye, Ear, Nose, and Throat in Durham.
Although the risks of periorbital steroid absorption are real, a limited course of low potency topical steroids is generally adequate for common periorbital indications, and these appear to be safe.
“There is insufficient evidence to link weak periocular topical corticosteroids such as desonide or hydrocortisone with ocular complications,” said Dr. Grace, suggesting that pediatric dermatologists can be reassured when using these medications at low concentrations.
“Potent periocular steroids have been associated with ocular complications, but this has typically involved exposures over months to years,” Dr. Grace specified.
When topical corticosteroids are applied at high concentrations on the face away from the periorbital area, glaucoma and other feared ophthalmic complications cannot be entirely ruled out, but, again, the risk is low in the absence of “very large quantities” of potent topical agents applied for lengthy periods of time, according to Dr. Grace, basing this observation on case studies.
In children, as in adults, the potential exception is a child with existing ocular disease. In such cases, or in children with risk factors for ocular disease, Dr. Grace recommends referral to an ophthalmologist for a baseline examination prior to a course of topical corticosteroids with the potential of periocular absorption. With a baseline assessment, adverse effects are more easily documented if exposure is prolonged.
The message, although not identical, is similar for use of dupilumab (Dupixent) or other biologics that target the interleukin-13 (IL-13) pathway. The potential for complications cannot be ignored but these are often time-limited and the benefit is likely to exceed the risk in children who have severe atopic dermatitis or other skin conditions for which these treatments are effective.
There are several potential mechanisms by which biologics targeting IL-13 might increase risk of ocular complications, one of which is the role that IL-13 plays in ocular mucus production, regulation of conjunctival goblet cells, and tear production, according to several published reports.
“Up to 30% of children will get some type of eye complication but, fortunately, most of them will not have to stop therapy,” Dr. Grace said. These side effects include conjunctivitis, blepharitis, keratitis, dry eye, and itching, but they are typically manageable. Topical steroids or calcineurin inhibitors can be offered if needed, but many of these conditions will self-resolve. Dr. Grace estimated that less than 1% of patients need to stop treatment because of ophthalmic side effects.
Lesions that obstruct vision
Dr. Grace urged pediatric dermatologists to be aware of the risk for amblyopia in young children with lesions that obstruct vision in one eye. In early development, prolonged obstruction of vision in one eye can alter neural communication with the brain, producing permanent vision impairment.
She explained that clearing the obstructed vision, whether from a capillary hemangioma or any periorbital growth, should be considered urgent to avoid irreversible damage.
Similarly, periorbital port-wine stains associated with Sturge-Weber syndrome, which is primarily a vascular disorder that predisposes children to glaucoma, represents a condition that requires prompt attention. Sturge-Weber syndrome is often but not always identified at birth, but it is a condition for which evaluation and treatment should involve the participation of an ophthalmologist.
Meibomian gland disease is another disorder that is often seen first by a pediatric dermatologist but also requires collaborative management. The challenge is sorting out the underlying cause or causes and initiating a therapy that unclogs the gland without having to resort to incision and drainage.
“Drainage is hard to do and is not necessarily effective,” explained Dr. Grace. While scrubs, warmth, and massage frequently are adequate to unclog the gland – which secretes meibum, a complex of lipids that perform several functions in protecting the eye – therapies specific to the cause, such as Demodex-related blepharitis, chalazions, and styes, might be needed.
Dr. Grace indicated that patience is often needed. The process of unclogging these glands often takes time, but she emphasized that a first-line conservative approach is always appropriate to avoid the difficulty and potential problems of incisions.
In general, these messages are not novel, but they provide a refresher for pediatric dermatologists who do not regularly confront complications that involve the eyes. According to session moderator, Elizabeth Neiman, MD, assistant professor of pediatric dermatology, University of North Carolina at Chapel Hill, the messages regarding topical steroids on the face and the eyes are “important” and worth emphasizing.
“It’s useful to reinforce the point that corticosteroids should be used when needed in the periorbital area [to control skin diseases] if they are used in low concentrations,” Dr. Neiman told this news organization.
Similarly, conjunctivitis and other ocular complications of dupilumab are a source of concern for parents as well as dermatologists. Dr. Neiman indicated that a review of the benefit-to-risk ratio is important when considering these treatments in patients with indications for severe skin disorders.
Dr. Grace and Dr. Nieman have no potential financial conflicts related to this topic.

Rising patient costs tied to private equity ownership
The report was a collaboration of University of California, Berkeley, staff and researchers from two nonprofits, the American Antitrust Institute and the Washington Center for Equitable Growth. It provides “convincing evidence that incentives to put profits before patients have grown stronger with an increase in private equity ownership of physician practices,” lead author Richard Scheffler, PhD, of UC Berkeley said in a statement.
The report also noted that private equity acquisitions of physician groups have risen sixfold in just a decade, increasing from 75 deals in 2012 to 484 deals in 2021.
Separately, the American Medical Association earlier released a separate report on trends in physician practice arrangements, finding that the percentage of physicians working in private equity–owned groups was 4.5% in 2022, the same as in its previous 2020 report. The share of physicians working in private practices fell by 13 percentage points from 60.1% to 46.7% between 2012 and 2022, the AMA reported.
The Berkeley report and the AMA update come amid rising concerns about the effects of the decline of independent physician practices. The U.S. Senate Finance Committee, which oversees most federal health spending, held a June hearing examining the causes and consequences of increased corporate ownership in health care, including a look at physician practices.
“It’s increasingly clear that consolidation in health care is not lowering costs or increasing the quality of Americans’ health care,” Senate Finance Chairman Ron Wyden (D-Ore.) said in an email. “For private equity in health care in particular, there needs to be more transparency around ownership so the effect on these business relationships can be better understood.”
Federal and state agencies do not generally track acquisitions of physician practices.
The UC Berkeley report impressively documents the rising influence of private equity in health care, for which it’s tough to find good data, said Karen Joynt Maddox, MD, MPH, of Washington University in St. Louis. Dr. Maddox, a cardiologist and policy researcher who also has studied the effects of consolidation in health care, examined the new report at the request of this news organization.
“They did a great job with the data,” Dr. Maddox said. “One of the big issues around private equity, and in general, ‘corporatization’ and consolidation of health care, is that there’s not a great way to track ownership changes. It’s really difficult to study.”
Dr. Scheffler and colleagues used data from the commercial firm PitchBook to identify acquisitions of physician practices by private equity firms. They consulted IQVIA’s physician databases – OneKey and SK&A Office-Based Physicians Database – to learn about the location, size, and specialties of acquired practices. They also used data from the nonprofit Health Care Cost Institute, which tracks commercial health plan claims, to assess how private equity acquisitions affected prices.
The researchers then matched the findings for practices acquired by private equity firms from 2015 to 2021 against those for comparable physician practices that remained independent from 2012 to 2021.
The authors then tied private-equity ownership to the following price increases:
- Gastroenterology (14%; 95% confidence interval, 7.9%-20.4%
- Oncology (16.4%; 95% CI, 5.5%-28.4%)
- Dermatology (4.0%; 95% CI, 1%-7.1%)
- Ob.gyn. (8.8%; 95% CI, 3.8%-14%)
- Ophthalmology (8.7%; 95% CI, 5.1%-12.3%)
- Radiology (8.2%; 95% CI, 0.8%-16.1%)
- Orthopedics (7.1%; 95% CI, 2.2%-12.3%)
- Primary care (4.1%; 95% CI, 1.3%-7%)
The analysis also found higher prices for cardiology (8.7%; 95% CI, –6.4% to 26.1%) and urology (4.2%; 95% CI, –2.3% to 11.1%), but neither of these findings was statistically significant, one of the authors, Daniel R. Arnold, PhD, of UC Berkeley, said in an email. This was most likely caused by smaller sample sizes for these fields.
Factors driving consolidation
The two reports and the Senate Finance consolidation hearing raised similar issues, including calls to look at the factors driving more physicians out of independent practice, including Medicare reimbursement that may not keep up with rising inflation.
The Berkeley report authors called for Congress to add a broad inflation component to the Medicare physician fee schedule. It also called on Congress to add cases where Medicare, the biggest U.S. purchaser of health care, pays less for services when performed in independent practices than in hospital-affiliated ones.
Shawn Martin, executive vice president and CEO of the American Academy of Family Physicians, said his group appreciates how the report from UC Berkeley and nonprofit groups echoed recommendations many clinicians have made, including the call for a broad inflation adjustment for the fee schedule.
“To move the needle forward, Congress must advance site-neutral payment policies while also addressing the administrative requirements that take physicians away from the important work of caring for patients,” Mr. Martin said in an email.
Arnold Ventures provided funding for the report, which was a joint project of the American Antitrust Institute, the Nicholas C. Petris Center on Health Care Markets and Consumer Welfare, UC Berkeley, and the Washington Center for Equitable Growth.

It provides “convincing evidence that incentives to put profits before patients have grown stronger with an increase in private equity ownership of physician practices,” lead author Richard Scheffler, PhD, of UC Berkeley said in a statement.
The report also noted that private equity acquisitions of physician groups have risen sixfold in just a decade, increasing from 75 deals in 2012 to 484 deals in 2021.
Separately, the American Medical Association earlier released a separate report on trends in physician practice arrangements, finding that the percentage of physicians working in private equity–owned groups was 4.5% in 2022, the same as in its previous 2020 report. The share of physicians working in private practices fell by 13 percentage points from 60.1% to 46.7% between 2012 and 2022, the AMA reported.
The Berkeley report and the AMA update come amid rising concerns about the effects of the decline of independent physician practices. The U.S. Senate Finance Committee, which oversees most federal health spending, held a June hearing examining the causes and consequences of increased corporate ownership in health care, including a look at physician practices.
“It’s increasingly clear that consolidation in health care is not lowering costs or increasing the quality of Americans’ health care,” Senate Finance Chairman Ron Wyden (D-Ore.) said in an email. “For private equity in health care in particular, there needs to be more transparency around ownership so the effect on these business relationships can be better understood.”
Federal and state agencies do not generally track acquisitions of physician practices.
The UC Berkeley report impressively documents the rising influence of private equity in health care, for which it’s tough to find good data, said Karen Joynt Maddox, MD, MPH, of Washington University in St. Louis. Dr. Maddox, a cardiologist and policy researcher who also has studied the effects of consolidation in health care, examined the new report at the request of this news organization.
“They did a great job with the data,” Dr. Maddox said. “One of the big issues around private equity, and in general, ‘corporatization’ and consolidation of health care, is that there’s not a great way to track ownership changes. It’s really difficult to study.”
Dr. Scheffler and colleagues used data from the commercial firm PitchBook to identify acquisitions of physician practices by private equity firms. They consulted IQVIA’s physician databases – OneKey and SK&A Office-Based Physicians Database – to learn about the location, size, and specialties of acquired practices. They also used data from the nonprofit Health Care Cost Institute, which tracks commercial health plan claims, to assess how private equity acquisitions affected prices.
The researchers then matched the findings for practices acquired by private equity firms from 2015 to 2021 against those for comparable physician practices that remained independent from 2012 to 2021.
The authors then tied private-equity ownership to the following price increases:
- Gastroenterology (14%; 95% confidence interval, 7.9%-20.4%
- Oncology (16.4%; 95% CI, 5.5%-28.4%)
- Dermatology (4.0%; 95% CI, 1%-7.1%)
- Ob.gyn. (8.8%; 95% CI, 3.8%-14%)
- Ophthalmology (8.7%; 95% CI, 5.1%-12.3%)
- Radiology (8.2%; 95% CI, 0.8%-16.1%)
- Orthopedics (7.1%; 95% CI, 2.2%-12.3%)
- Primary care (4.1%; 95% CI, 1.3%-7%)
The analysis also found higher prices for cardiology (8.7%; 95% CI, –6.4% to 26.1%) and urology (4.2%; 95% CI, –2.3% to 11.1%), but neither of these findings was statistically significant, one of the authors, Daniel R. Arnold, PhD, of UC Berkeley, said in an email. This was most likely caused by smaller sample sizes for these fields.
Factors driving consolidation
The two reports and the Senate Finance consolidation hearing raised similar issues, including calls to look at the factors driving more physicians out of independent practice, including Medicare reimbursement that may not keep up with rising inflation.
The Berkeley report authors called for Congress to add a broad inflation component to the Medicare physician fee schedule. It also called on Congress to add cases where Medicare, the biggest U.S. purchaser of health care, pays less for services when performed in independent practices than in hospital-affiliated ones.
Shawn Martin, executive vice president and CEO of the American Academy of Family Physicians, said his group appreciates how the report from UC Berkeley and nonprofit groups echoed recommendations many clinicians have made, including the call for a broad inflation adjustment for the fee schedule.
“To move the needle forward, Congress must advance site-neutral payment policies while also addressing the administrative requirements that take physicians away from the important work of caring for patients,” Mr. Martin said in an email.
Arnold Ventures provided funding for the report, which was a joint project of the American Antitrust Institute, the Nicholas C. Petris Center on Health Care Markets and Consumer Welfare, UC Berkeley, and the Washington Center for Equitable Growth.

Case report describes pediatric RIME triggered by norovirus
, according to a newly published case report.
Lead author Anna Yasmine Kirkorian, MD, chief of dermatology at Children’s National Hospital in Washington, said she wanted to get the word out in part because it seems like RIME is occurring more frequently. “I do feel like we’re seeing more cases and from a more diverse number of pathogens,” Dr. Kirkorian told this news organization.
There was a decrease in RIME during the early stages of the COVID-19 pandemic when people were isolating more, Dr. Kirkorian said. SARS-CoV-2 has been a trigger for some cases, but she did not find that remarkable, given that respiratory viruses are known RIME precursors. The question is why RIME is being triggered more frequently now that people have essentially gone back to their normal lives, she said.
Dr. Kirkorian and colleagues at Children’s National Hospital and George Washington University, Washington, wrote about a 5-year-old boy with norovirus-triggered RIME in a case report published in Pediatric Dermatology.
RIME – previously known as Mycoplasma pneumoniae–induced rash and mucositis (MIRM) – tends to arise after a viral infection, with upper respiratory viruses such as mycoplasma and Chlamydophila pneumoniae, influenza, and enterovirus among the common triggers. “We think this is actually your own immune system overreacting to a pathogen,” Dr. Kirkorian said in an interview, adding that the mechanism of RIME is still not understood.
While the norovirus discovery was a surprise, it shows that much is still unknown about this rare condition. “I don’t think we know what is usual and what is unusual,” Dr. Kirkorian said.
In this case, the boy swiftly declined, with progressive conjunctivitis, high fever, and rapidly developing mucositis. By the time the 5-year-old got to Children’s National Hospital, he had a spreading, painful rash, including tense vesicles and bullae involving more than 30% of his total body surface area, and areas of denuded skin on both cheeks and the back of his neck.
He had hemorrhagic mucositis of the lips, a large erosion at the urethral meatus, and hemorrhagic conjunctivitis of both eyes with thick yellow crusting on the eyelids.
The clinicians intubated the boy and admitted him to the intensive care unit. He was given a one-time injection of etanercept (25 mg) followed by 8 days of intravenous cyclosporine at a dose of 5 mg per kilogram, divided twice daily, which helped calm the mucositis and stopped the rash from progressing. There is not an accepted protocol or list of evidence-based therapeutics for RIME, Dr. Kirkorian noted.
The severe eye damage required amniotic membrane grafts. The patient was extubated after 9 days but remained in the hospital for a total of 26 days because he needed to receive nutritional support (the mucositis kept him from eating), and for pain control and weaning of sedation.
As the clinicians searched for a potential triggering virus, they came up empty. Results were negative for adenovirus, Epstein Barr virus, cytomegalovirus, herpes simplex, and varicella zoster. But they noted that the child’s household contacts had all been sick a week before with presumed viral gastroenteritis. They decided to run a stool screen and the polymerase chain reaction for norovirus was positive. The boy never had GI symptoms.
Dr. Kirkorian said in the interview that she has seen other RIME cases where a child did not have symptoms associated with the original virus but did have a sudden onset of mucositis.
Although the definition of RIME is evolving, it is defined in part by mucositis in at least two of three areas: the mouth, eyes, and genitals. “Once you have the inflammation of the mucous membranes you should be on alert to think about more serious conditions,” like RIME, said Dr. Kirkorian. “Why does it manifest with the mucositis? I don’t think we know that,” she added.
RIME recurrence has also been vexing for patients, families and clinicians. In May, at the annual Atlantic Dermatology Conference, held in Baltimore, Dr. Kirkorian also discussed an 11-year-old patient who had RIME after SARS-CoV-2 infection early in the pandemic, resulting in a 22-day hospitalization and placement of a peripherally inserted central catheter and a feeding tube. He improved with cyclosporine and was discharged on systemic tacrolimus.
He was fine for several years, until another COVID infection. He again responded to medication. But not long after, an undetermined viral infection triggered another episode of RIME.
Dr. Kirkorian said there is no way to predict recurrence – making a devastating condition all the more worrisome. “Knowing that it might come back and it’s totally haphazard as to what might make it come back – that is very stressful for families,” she said in the interview.
“Some of the most perplexing patients with RIME are those with recurrent disease,” wrote Warren R. Heymann, MD, professor of dermatology and pediatrics at Rowan University, Camden, N.J., wrote in an online column on RIME in the American Academy of Dermatology’s “Dermatology World Insights and Inquiries”.
“Recurrent RIME is of particular interest, given that we could potentially intervene and prevent additional disease,” wrote Camille Introcaso, MD, associate professor of medicine at Rowan University, in response to Dr. Heymann’s remarks. “Although multiple possible mechanisms for the clinical findings of RIME have been proposed, including molecular mimicry between infectious agent proteins and keratinocyte antigens, immune complex deposition, and combinations of medication and infection, the pathophysiology is unknown,” she added.
In the interview, Dr. Kirkorian said that she and colleagues in the Pediatric Dermatology Research Alliance (PeDRA) are trying to assemble more multicenter trials to assess the underlying pathology of RIME, effectiveness of various treatments, and to “find some predictive factors.” Given that RIME is an acute-onset emergency, it is not easy to conduct randomized controlled trials, she added.
Dr. Kirkorian, Dr. Heymann, and Dr. Introcaso report no relevant financial relationships.

Infection-related chronic illness: A new paradigm for research and treatment
Experience with long COVID has shone a spotlight on persistent Lyme disease and other often debilitating chronic illnesses that follow known or suspected infections – and on the urgent need for a common and well-funded research agenda, education of physicians, growth of multidisciplinary clinics, and financially supported clinical care.
“We critically need to understand the epidemiology and pathogenesis of chronic symptoms, and identify more effective ways to manage, treat, and potentially cure these illnesses,” Lyle Petersen, MD, MPH, director of the division of vector-borne diseases at the Centers for Disease Control and Prevention, said at the start of a 2-day National Academies of Science, Engineering, and Medicine (NASEM) workshop, “Toward a Common Research Agenda in Infection-Associated Chronic Illnesses.”
Thinking about infection-associated chronic illnesses as an entity – one predicated on commonalities in chronic symptoms and in leading hypotheses for causes – represents a paradigm shift that researchers and patient advocates said can avoid research redundancies and is essential to address what the NASEM calls an overlooked, growing public health problem.
An estimated 2 million people in the United States are living with what’s called posttreatment Lyme disease (PTLD) – a subset of patients with persistent or chronic Lyme disease – and an estimated 1.7-3.3 million people in the United States have diagnoses of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). More than 700,000 people are living with multiple sclerosis. And as of January 2023, 11% of people in the United States reported having long COVID symptoms; the incidence of long COVID is currently estimated at 10%-30% of nonhospitalized cases of COVID-19.
These illnesses “have come under one umbrella,” said Avindra Nath, MD, clinical director of the National Institute of Neurologic Disorders and Stroke (NINDS), Bethesda, Md.
To date, common ground in the literature has grown largely around long COVID and ME/CFS, the latter of which is often associated with a prior, often unidentified infection.
Symptoms of both have been “rigorously” studied and shown to have overlaps, and the illnesses appear to share underlying biologic abnormalities in metabolism and the gut microbiome, as well as viral reactivation and abnormalities in the immune system, central and autonomic nervous systems, and the cardiovascular and pulmonary systems, said Anthony L. Komaroff, MD, professor of medicine at Harvard Medical School and a senior physician at Brigham & Women’s Hospital, both in Boston. (An estimated half of patients with long COVID meet the diagnostic criteria for ME/CFS.)
Although less thoroughly researched, similar symptoms are experienced by a subset of people following a variety of viral, bacterial, and protozoal infections, Dr. Komaroff said. To be determined, he said, is whether the pathophysiology believed to be shared by long COVID and ME/CFS is also shared with other postinfectious syndromes following acute illness with Ebola, West Nile, dengue, mycoplasma pneumonia, enteroviruses, and other pathogens, he said.
Persistent infection, viral reactivation
RNA viral infections can lead to persistent inflammation and dysregulated immunity, with or without viral persistence over time, Timothy J. Henrich, MD, MMSc, associate professor of medicine at the University of California, San Francisco, said in a keynote address.
Research on Ebola survivors has documented long-lasting inflammation and severe immune dysfunction 2 years after infection, for instance. And it’s well known that HIV-1 leads to aberrant immune responses, inflammation, and organ damage despite antiretroviral therapy, said Dr. Henrich, who leads a laboratory/research group that studies approaches to HIV-1 cure and PET-based imaging approaches to characterize viral reservoirs and immune sequelae.
Viral persistence, which can be difficult to measure, has also been documented in Ebola survivors. And in patients living with HIV-1, HIV-1 RNA and protein expression have been shown to persist, again despite antiretroviral therapy. The UCSF Long-Term Immunological Impact of Novel Coronavirus (LIINC) study, for which Dr. Henrich is the principal investigator, found spike RNA in colorectal tissue more than 22 months post COVID, and other research documented viral protein in gut tissue for up to 6 months, he said.
“I think we’re appreciating now, in at least the scientific and treatment community, that there’s a potential for ‘acute’ infections to exhibit some degree of persistence leading to clinical morbidity,” said Dr. Henrich, one of several speakers to describe reports of pathogen persistence. Regarding long COVID, its “etiology is likely heterogeneous,” he said, but persistence of SARS-CoV-2 “may lay behind” other described mechanisms, from clotting/microvascular dysfunction to inflammation and tissue damage to immune dysregulation.
Reactivation of existing latent viral infections in the setting of new acute microbial illness may also play an etiologic role in chronic illnesses, Dr. Henrich said. Epstein-Barr virus (EBV) reactivation has been shown in some studies, including their UCSF COVID-19 cohort, to be associated with long COVID.
“Physicians have been trained to be skeptical about the role [of latent viral infections],” Michael Peluso, MD, an infectious disease physician and assistant professor at UCSF, said during a talk on viral reactivation. This skepticism needs to be “reexamined and overcome,” he said.
Herpesviruses have frequently been associated with ME/CFS, he noted. And evidence of a strong association between EBV and multiple sclerosis came recently from a prospective study of 10 million military recruits that found a 32-fold increased risk of MS after EBV infection but no increase after infection with other viruses, Dr. Peluso and Dr. Henrich both noted.
Research needs, treatment trials
Research needs are vast: The need to learn more about the mechanisms of pathogen persistence and immune evasion, for instance, and the need for more biomarker studies, more imaging studies and tissue analyses, more study of microbiome composition and activity, and continued development and application of metagenomic next-generation sequencing.
Workshop participants also spoke of the need to better understand the molecular mimicry that can occur between pathogen-produced proteins and self-antigens, for instance, and the effects of inflammation and infection-related immune changes on neuronal and microglial function in the brain.
“We should perform similar forms of analysis [across] patients with different infection-associated chronic conditions,” said Amy Proal, PhD, president of the PolyBio Research Foundation, which funds research on infection-associated chronic infections. And within individual conditions and well-characterized study groups “we should perform many different forms of analysis … so we can define endotypes and get more solid biomarkers so that industry [will have more confidence] to run clinical trials.”
In the meantime, patients need fast-moving treatment trials for long COVID, long Lyme, and other infection-associated chronic illnesses, speakers emphasized. “We all agree that treatment trials are overdue,” said the NINDS’ Dr. Nath. “We can’t afford to wait for another decade until we understand all the mechanisms, but rather we can do clinical trials based on what we understand now and study the pathophysiology in the context of the clinical trials.”
Just as was done with HIV, said Steven G. Deeks, MD, professor of medicine at UCSF, researchers must “practice experimental medicine” and select pathways and mechanisms of interest, interrupt those pathways in a controlled manner, and assess impact. “Much of this can be done by repurposing existing drugs,” he said, like antivirals for persistent viral infection, EBV-directed therapies for EBV reactivation, anti-inflammatory drugs for inflammation, B–cell-directed therapies for autoantibodies, and antiplatelet drugs for microvascular disease.
When done correctly, he said, such “probe” studies can deepen mechanistic understandings, lead to biomarkers, and provide proof-of-concept that “will encourage massive investment in developing new therapies” for long COVID and other infection-associated chronic illnesses.
Trials of treatments for long COVID “are starting, so I’m optimistic,” said Dr. Deeks, an expert on HIV pathogenesis and treatment and a principal investigator of the Researching COVID to Enhance Recovery (RECOVER) study. Among the trials: A study of intravenous immunoglobulin (IVIG) for neurologic long COVID; a study of an anti-SARS-CoV-2 monoclonal antibody that can deplete tissue/cellular reservoirs of viral particles (replicating or not); and a study evaluating baricitinib (Olumiant), a Janus kinase inhibitor, for neurocognitive impairment and cardiopulmonary symptoms of long COVID.
Alessio Fasano, MD, professor of pediatrics at Harvard Medical School and professor of nutrition at the Harvard T.H. Chan School of Public Health, Boston, described at the workshop how he began investigating the use of larazotide acetate – an inhibitor of the protein zonulin, which increases intestinal permeability – in children with COVID-19 Multisystem Inflammatory Syndrome (MIS-C) after learning that SARS-CoV-2 viral particles persist in the gastrointestinal tract, causing dysbiosis and zonulin upregulation.
In an ongoing phase 2, double-blind, placebo-controlled trial, the agent thus far has expedited the resolution of gastrointestinal symptoms and clearance of spike protein from the circulation, he said. A phase 2 trial of the agent for pediatric patients with long COVID and SARS-CoV-2 antigenemia is underway. “What if we were to stop [chains of events] by stopping the passage of elements from the virus into circulation?’ he said.
In the realm of Lyme disease, a recently launched Clinical Trials Network for Lyme and Other Tick-Borne Diseases has awarded pilot study grants to evaluate treatments aimed at a variety of possible disease mechanisms that, notably, are similar to those of other chronic illnesses: persistence of infection or remnants of infection, immune dysregulation and autoimmune reactions, neural dysfunction, and gut microbiome changes. (Microclots and mitochondrial dysfunction have not been as well studied in Lyme.)
Current and upcoming studies include evaluations of transcutaneous auricular vagus nerve stimulation for those with persistent Lyme fatigue, transcranial direct current stimulation with cognitive retraining for Lyme brain fog, and tetracycline for PTLD, said Brian Fallon, MD, MPH, professor of clinical psychiatry at Columbia University, New York, who directs the Lyme & Tick-Borne Diseases Research Center and the coordinating center of the new network.
Moving forward, he said, it is important to loosen exclusion criteria and include patients with “probable or possible” Lyme and those with suspected infections with other tick-borne pathogens. All told, these patients comprise a large portion of those with chronic symptoms and have been neglected in an already thin research space, Dr. Fallon said, noting that “there haven’t been any clinical trials of posttreatment Lyme disease in ages – in 10-15 years.”
(PTLD refers to symptoms lasting for more than 6 months after the completion of standard Infectious Diseases Society of America–recommended antibiotic protocols. It occurs in about 15% of patients, said John Aucott, MD, director of the Johns Hopkins Lyme Disease Research Center, Baltimore, a member of the new clinical trials network.)
Calls for a new NIH center and patient involvement
Patients and patient advocacy organizations have played a vital role in research thus far: They’ve documented post-COVID symptoms that academic researchers said they would not otherwise have known of. Leaders of the Patient-Led Research Collaborative have coauthored published reviews with leading long COVID experts. And patients with tick-borne illnesses have enrolled in the MyLymeData patient registry run by LymeDisease.org, which has documented patient-experienced efficacy of alternative treatments and described antibiotic responders and nonresponders.
At the workshop, they shared findings alongside academic experts, and researchers called for their continued involvement. “Patient engagement at every step of the research process is critical,” Dr. Nath said.
“We need to ensure that research is reflective of lived experiences … and [that we’re] accelerating clinical trials of therapeutics that are of priority to the patient community,” said Lisa McCorkell, cofounder of the long COVID-focused Patient-Led Research Collaborative.
Ms. McCorkell also called for the creation of an office for infection-associated chronic illnesses in the NIH director’s office. Others voiced their support. “I think it’s a great idea to have an NIH center for infection-associated chronic illnesses,” said Dr. Fallon. “I think it would have a profound impact.”
The other great need, of course, is funding. “We have ideas, we have drugs that can be repurposed, we have a highly informed and engaged community that will enroll in and be retained in studies, and we have outcomes we can measure,” Dr. Deeks said. “What we’re missing is industry engagement and funding. We need massive engagement from the NIH.”
Real-world treatment needs
In the meantime, patients are seeking treatment, and “clinicians need to have uncertainty tolerance” and try multiple treatments simultaneously, said David Putrino, PT, PhD, director of rehabilitation innovation for the Mount Sinai Health System and professor of rehabilitation and human performance at the Icahn School of Medicine at Mount Sinai, New York. He oversees a multidisciplinary hybrid clinical care research center that has seen over 1,500 patients with long COVID and is beginning to see patients with other infection-associated chronic illnesses.
It’s a model that should be replicated to help fill the “enormous unmet clinical need” of patients with infection-associated chronic illness, said Peter Rowe, MD, professor of pediatrics at the Johns Hopkins School of Medicine and an expert on ME/CFS. And “as we request [more research funding], we will also need [financial] support for clinical care,” he emphasized, to provide equitable access for patients and to attract treating physicians.
Moreover, said Linda Geng, MD, PhD, the culture of stigma needs to change. Right now, patients with long COVID often feel dismissed not only by friends, families, and coworkers, but by clinicians who find it find it hard “to grasp that this is real and a biological condition.”
And it’s not just conditions such as long COVID that are stigmatized, but treatments as well, she said. For instance, some clinicians view low-dose naltrexone, a treatment increasingly being used for inflammation, with suspicion because it is used for opioid use disorder and alcohol use disorder – or because the “low-dose” label summons mistrust of homeopathy. “Even with therapies, there are preconceived notions and biases,” said Dr. Geng, cofounder and codirector of the Stanford (Calif.) Long COVID program.
“What almost killed me,” said Meghan O’Rourke, who has ongoing effects from long-undiagnosed tick-borne illness, “was the invisibility of the illness.” Ms. O’Rourke teaches at Yale University and is the author of “The Invisible Kingdom: Reimagining Chronic Illness.”
Teaching young physicians about these illnesses would help, she and others said. During a question and answer session, Dr. Putrino shared that the Icahn School of Medicine has recently committed to “create a complex chronic illness medical curriculum” that will impact medical education from the first year of medical school through residencies. Dr. Putrino said his team is also working on materials to help other clinics develop care models similar to those at his Mount Sinai clinic.

Experience with long COVID has shone a spotlight on persistent Lyme disease and other often debilitating chronic illnesses that follow known or suspected infections – and on the urgent need for a common and well-funded research agenda, education of physicians, growth of multidisciplinary clinics, and financially supported clinical care.
“We critically need to understand the epidemiology and pathogenesis of chronic symptoms, and identify more effective ways to manage, treat, and potentially cure these illnesses,” Lyle Petersen, MD, MPH, director of the division of vector-borne diseases at the Centers for Disease Control and Prevention, said at the start of a 2-day National Academies of Science, Engineering, and Medicine (NASEM) workshop, “Toward a Common Research Agenda in Infection-Associated Chronic Illnesses.”
Thinking about infection-associated chronic illnesses as an entity – one predicated on commonalities in chronic symptoms and in leading hypotheses for causes – represents a paradigm shift that researchers and patient advocates said can avoid research redundancies and is essential to address what the NASEM calls an overlooked, growing public health problem.
An estimated 2 million people in the United States are living with what’s called posttreatment Lyme disease (PTLD) – a subset of patients with persistent or chronic Lyme disease – and an estimated 1.7-3.3 million people in the United States have diagnoses of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). More than 700,000 people are living with multiple sclerosis. And as of January 2023, 11% of people in the United States reported having long COVID symptoms; the incidence of long COVID is currently estimated at 10%-30% of nonhospitalized cases of COVID-19.
These illnesses “have come under one umbrella,” said Avindra Nath, MD, clinical director of the National Institute of Neurologic Disorders and Stroke (NINDS), Bethesda, Md.
To date, common ground in the literature has grown largely around long COVID and ME/CFS, the latter of which is often associated with a prior, often unidentified infection.
Symptoms of both have been “rigorously” studied and shown to have overlaps, and the illnesses appear to share underlying biologic abnormalities in metabolism and the gut microbiome, as well as viral reactivation and abnormalities in the immune system, central and autonomic nervous systems, and the cardiovascular and pulmonary systems, said Anthony L. Komaroff, MD, professor of medicine at Harvard Medical School and a senior physician at Brigham & Women’s Hospital, both in Boston. (An estimated half of patients with long COVID meet the diagnostic criteria for ME/CFS.)
Although less thoroughly researched, similar symptoms are experienced by a subset of people following a variety of viral, bacterial, and protozoal infections, Dr. Komaroff said. To be determined, he said, is whether the pathophysiology believed to be shared by long COVID and ME/CFS is also shared with other postinfectious syndromes following acute illness with Ebola, West Nile, dengue, mycoplasma pneumonia, enteroviruses, and other pathogens, he said.
Persistent infection, viral reactivation
RNA viral infections can lead to persistent inflammation and dysregulated immunity, with or without viral persistence over time, Timothy J. Henrich, MD, MMSc, associate professor of medicine at the University of California, San Francisco, said in a keynote address.
Research on Ebola survivors has documented long-lasting inflammation and severe immune dysfunction 2 years after infection, for instance. And it’s well known that HIV-1 leads to aberrant immune responses, inflammation, and organ damage despite antiretroviral therapy, said Dr. Henrich, who leads a laboratory/research group that studies approaches to HIV-1 cure and PET-based imaging approaches to characterize viral reservoirs and immune sequelae.
Viral persistence, which can be difficult to measure, has also been documented in Ebola survivors. And in patients living with HIV-1, HIV-1 RNA and protein expression have been shown to persist, again despite antiretroviral therapy. The UCSF Long-Term Immunological Impact of Novel Coronavirus (LIINC) study, for which Dr. Henrich is the principal investigator, found spike RNA in colorectal tissue more than 22 months post COVID, and other research documented viral protein in gut tissue for up to 6 months, he said.
“I think we’re appreciating now, in at least the scientific and treatment community, that there’s a potential for ‘acute’ infections to exhibit some degree of persistence leading to clinical morbidity,” said Dr. Henrich, one of several speakers to describe reports of pathogen persistence. Regarding long COVID, its “etiology is likely heterogeneous,” he said, but persistence of SARS-CoV-2 “may lay behind” other described mechanisms, from clotting/microvascular dysfunction to inflammation and tissue damage to immune dysregulation.
Reactivation of existing latent viral infections in the setting of new acute microbial illness may also play an etiologic role in chronic illnesses, Dr. Henrich said. Epstein-Barr virus (EBV) reactivation has been shown in some studies, including their UCSF COVID-19 cohort, to be associated with long COVID.
“Physicians have been trained to be skeptical about the role [of latent viral infections],” Michael Peluso, MD, an infectious disease physician and assistant professor at UCSF, said during a talk on viral reactivation. This skepticism needs to be “reexamined and overcome,” he said.
Herpesviruses have frequently been associated with ME/CFS, he noted. And evidence of a strong association between EBV and multiple sclerosis came recently from a prospective study of 10 million military recruits that found a 32-fold increased risk of MS after EBV infection but no increase after infection with other viruses, Dr. Peluso and Dr. Henrich both noted.
Research needs, treatment trials
Research needs are vast: The need to learn more about the mechanisms of pathogen persistence and immune evasion, for instance, and the need for more biomarker studies, more imaging studies and tissue analyses, more study of microbiome composition and activity, and continued development and application of metagenomic next-generation sequencing.
Workshop participants also spoke of the need to better understand the molecular mimicry that can occur between pathogen-produced proteins and self-antigens, for instance, and the effects of inflammation and infection-related immune changes on neuronal and microglial function in the brain.
“We should perform similar forms of analysis [across] patients with different infection-associated chronic conditions,” said Amy Proal, PhD, president of the PolyBio Research Foundation, which funds research on infection-associated chronic infections. And within individual conditions and well-characterized study groups “we should perform many different forms of analysis … so we can define endotypes and get more solid biomarkers so that industry [will have more confidence] to run clinical trials.”
In the meantime, patients need fast-moving treatment trials for long COVID, long Lyme, and other infection-associated chronic illnesses, speakers emphasized. “We all agree that treatment trials are overdue,” said the NINDS’ Dr. Nath. “We can’t afford to wait for another decade until we understand all the mechanisms, but rather we can do clinical trials based on what we understand now and study the pathophysiology in the context of the clinical trials.”
Just as was done with HIV, said Steven G. Deeks, MD, professor of medicine at UCSF, researchers must “practice experimental medicine” and select pathways and mechanisms of interest, interrupt those pathways in a controlled manner, and assess impact. “Much of this can be done by repurposing existing drugs,” he said, like antivirals for persistent viral infection, EBV-directed therapies for EBV reactivation, anti-inflammatory drugs for inflammation, B–cell-directed therapies for autoantibodies, and antiplatelet drugs for microvascular disease.
When done correctly, he said, such “probe” studies can deepen mechanistic understandings, lead to biomarkers, and provide proof-of-concept that “will encourage massive investment in developing new therapies” for long COVID and other infection-associated chronic illnesses.
Trials of treatments for long COVID “are starting, so I’m optimistic,” said Dr. Deeks, an expert on HIV pathogenesis and treatment and a principal investigator of the Researching COVID to Enhance Recovery (RECOVER) study. Among the trials: A study of intravenous immunoglobulin (IVIG) for neurologic long COVID; a study of an anti-SARS-CoV-2 monoclonal antibody that can deplete tissue/cellular reservoirs of viral particles (replicating or not); and a study evaluating baricitinib (Olumiant), a Janus kinase inhibitor, for neurocognitive impairment and cardiopulmonary symptoms of long COVID.
Alessio Fasano, MD, professor of pediatrics at Harvard Medical School and professor of nutrition at the Harvard T.H. Chan School of Public Health, Boston, described at the workshop how he began investigating the use of larazotide acetate – an inhibitor of the protein zonulin, which increases intestinal permeability – in children with COVID-19 Multisystem Inflammatory Syndrome (MIS-C) after learning that SARS-CoV-2 viral particles persist in the gastrointestinal tract, causing dysbiosis and zonulin upregulation.
In an ongoing phase 2, double-blind, placebo-controlled trial, the agent thus far has expedited the resolution of gastrointestinal symptoms and clearance of spike protein from the circulation, he said. A phase 2 trial of the agent for pediatric patients with long COVID and SARS-CoV-2 antigenemia is underway. “What if we were to stop [chains of events] by stopping the passage of elements from the virus into circulation?’ he said.
In the realm of Lyme disease, a recently launched Clinical Trials Network for Lyme and Other Tick-Borne Diseases has awarded pilot study grants to evaluate treatments aimed at a variety of possible disease mechanisms that, notably, are similar to those of other chronic illnesses: persistence of infection or remnants of infection, immune dysregulation and autoimmune reactions, neural dysfunction, and gut microbiome changes. (Microclots and mitochondrial dysfunction have not been as well studied in Lyme.)
Current and upcoming studies include evaluations of transcutaneous auricular vagus nerve stimulation for those with persistent Lyme fatigue, transcranial direct current stimulation with cognitive retraining for Lyme brain fog, and tetracycline for PTLD, said Brian Fallon, MD, MPH, professor of clinical psychiatry at Columbia University, New York, who directs the Lyme & Tick-Borne Diseases Research Center and the coordinating center of the new network.
Moving forward, he said, it is important to loosen exclusion criteria and include patients with “probable or possible” Lyme and those with suspected infections with other tick-borne pathogens. All told, these patients comprise a large portion of those with chronic symptoms and have been neglected in an already thin research space, Dr. Fallon said, noting that “there haven’t been any clinical trials of posttreatment Lyme disease in ages – in 10-15 years.”
(PTLD refers to symptoms lasting for more than 6 months after the completion of standard Infectious Diseases Society of America–recommended antibiotic protocols. It occurs in about 15% of patients, said John Aucott, MD, director of the Johns Hopkins Lyme Disease Research Center, Baltimore, a member of the new clinical trials network.)
Calls for a new NIH center and patient involvement
Patients and patient advocacy organizations have played a vital role in research thus far: They’ve documented post-COVID symptoms that academic researchers said they would not otherwise have known of. Leaders of the Patient-Led Research Collaborative have coauthored published reviews with leading long COVID experts. And patients with tick-borne illnesses have enrolled in the MyLymeData patient registry run by LymeDisease.org, which has documented patient-experienced efficacy of alternative treatments and described antibiotic responders and nonresponders.
At the workshop, they shared findings alongside academic experts, and researchers called for their continued involvement. “Patient engagement at every step of the research process is critical,” Dr. Nath said.
“We need to ensure that research is reflective of lived experiences … and [that we’re] accelerating clinical trials of therapeutics that are of priority to the patient community,” said Lisa McCorkell, cofounder of the long COVID-focused Patient-Led Research Collaborative.
Ms. McCorkell also called for the creation of an office for infection-associated chronic illnesses in the NIH director’s office. Others voiced their support. “I think it’s a great idea to have an NIH center for infection-associated chronic illnesses,” said Dr. Fallon. “I think it would have a profound impact.”
The other great need, of course, is funding. “We have ideas, we have drugs that can be repurposed, we have a highly informed and engaged community that will enroll in and be retained in studies, and we have outcomes we can measure,” Dr. Deeks said. “What we’re missing is industry engagement and funding. We need massive engagement from the NIH.”

In the meantime, patients are seeking treatment, and “clinicians need to have uncertainty tolerance” and try multiple treatments simultaneously, said David Putrino, PT, PhD, director of rehabilitation innovation for the Mount Sinai Health System and professor of rehabilitation and human performance at the Icahn School of Medicine at Mount Sinai, New York. He oversees a multidisciplinary hybrid clinical care research center that has seen over 1,500 patients with long COVID and is beginning to see patients with other infection-associated chronic illnesses.
