Study affirms shorter regimens for drug-resistant tuberculosis
Two short-course bedaquiline-containing treatment regimens for rifampicin-resistant tuberculosis showed “robust evidence” for superior efficacy and less ototoxicity compared to a 9-month injectable control regimen, researchers report.
The findings validate the World Health Organization’s current recommendation of a 9-month, bedaquiline-based oral regimen, “which was based only on observational data,” noted lead author Ruth Goodall, PhD, from the Medical Research Council Clinical Trials Unit at University College London, and colleagues.
The study was published in The Lancet.
The Standard Treatment Regimen of Anti-tuberculosis Drugs for Patients With MDR-TB (STREAM) stage 2 study was a randomized, phase 3, noninferiority trial conducted at 13 hospital clinics in seven countries that had prespecified tests for superiority if noninferiority was shown. The study enrolled individuals aged 15 years or older who had rifampicin-resistant TB without fluoroquinolone or aminoglycoside resistance.
The study’s first stage, STREAM stage 1, showed that The 9-month regimen was recommended by the WHO in 2016. That recommendation was superceded in 2020 when concerns of hearing loss associated with aminoglycosides prompted the WHO to endorse a 9-month bedaquiline-containing, injectable-free alternative, the authors write.
Seeking shorter treatment for better outcomes
STREAM stage 2 used a 9-month injectable regimen as its control. The investigators measured it against a fully oral 9-month bedaquiline-based treatment (primary comparison), as well as a 6-month oral bedaquiline regimen that included 8 weeks of a second-line injectable (secondary comparison).
The 9-month fully oral treatment included levofloxacin, clofazimine, ethambutol, and pyrazinamide for 40 weeks; bedaquiline, high-dose isoniazid, and prothionamide were given for the 16-week intensive phase.
The 6-month regimen included bedaquiline, clofazimine, pyrazinamide, and levofloxacin for 28 weeks, supplemented by high-dose isoniazid with kanamycin for an 8-week intensive phase.
For both comparisons, the primary outcome was favorable status at 76 weeks, defined as cultures that were negative for Mycobacterium tuberculosis without a preceding unfavorable outcome (defined as any death, bacteriologic failure or recurrence, or major treatment change).
Among 517 participants in the modified intention-to-treat population across the study groups, 62% were men, and 38% were women (median age, 32.5 years).
For the primary comparison, 71% of the control group and 83% of the oral regimen group had a favorable outcome.
In the secondary comparison, 69% had a favorable outcome in the control group, compared with 91% of those receiving the 6-month regimen.
Although the rate of grade 3 or 4 adverse events was similar in all three groups, there was significantly less ototoxicity among patients who received the oral regimen, compared with control patients (2% vs. 9%); 4% of those taking the 6-month regimen had hearing loss, compared with 8% of control patients.
Exploratory analyses comparing both bedaquiline-containing regimens revealed a significantly higher proportion of favorable outcomes among participants receiving the 6-month regimen (91%), compared with patients taking the fully oral 9-month regimen (79%). There were no significant differences in the rate of grade 3 or 4 adverse events.
The trial’s main limitation was its open-label design, which might have influenced decisions about treatment change, note the investigators.
“STREAM stage 2 has shown that two short-course, bedaquiline-containing regimens are not only non-inferior but superior to a 9-month injectable-containing regimen,” they conclude.
“The STREAM stage 2 fully oral regimen avoided the toxicity of aminoglycosides, and the 6-month regimen was highly effective, with reduced levels of ototoxicity. These two regimens offer promising treatment options for patients with MDR or rifampicin-resistant tuberculosis,” the authors write.
Dr. Goodall added, “Although both STREAM regimens were very effective, participants experienced relatively high levels of adverse events during the trial (though many of these were likely due to the close laboratory monitoring of the trial).
“While hearing loss was reduced on the 6-month regimen, it was not entirely eliminated,” she said. “Other new regimens in the field containing the medicine linezolid report side effects such as anemia and peripheral neuropathy. So more work needs to be done to ensure the treatment regimens are as safe and tolerable for patients as possible. In addition, even 6 months’ treatment is long for patients to tolerate, and further regimen shortening would be a welcome development for patients and health systems.”
‘A revolution in MDR tuberculosis’
“The authors must be commended on completing this challenging high-quality, phase 3, non-inferiority, randomized controlled trial involving 13 health care facilities across Ethiopia, Georgia, India, Moldova, Mongolia, South Africa, and Uganda ... despite the COVID-19 pandemic,” noted Keertan Dheda, MD, PhD, and Christoph Lange, MD, PhD, in an accompanying comment titled, “A Revolution in the Management of Multidrug-Resistant Tuberculosis”.
Although the WHO recently approved an all-oral 6-month bedaquiline, pretomanid, and linezolid plus moxifloxacin (BPaLM) regimen, results from the alternate 6-month regimen examined in STREAM stage 2 “do provide confidence in using 2 months of an injectable as part of a salvage regimen in patients for whom MDR tuberculosis treatment is not successful” or in those with extensively drug-resistant (XDR) or pre-XDR TB, “for whom therapeutic options are few,” noted Dr. Dheda, from the University of Cape Town (South Africa) and the London School of Hygiene and Tropical Medicine, and Dr. Lange, from the University of Lübeck (Germany), Baylor College of Medicine, and Texas Children’s Hospital, both in Houston.
The study authors and the commentators stress that safer and simpler treatments are still needed for MDR TB. “The search is now on for regimens that could further reduce duration, toxicity, and pill burden,” note Dr. Dheda and Dr. Lange.
However, they also note that “substantial resistance” to bedaquiline is already emerging. “Therefore, if we are to protect key drugs from becoming functionally redundant, drug-susceptibility testing capacity will need to be rapidly improved to minimize resistance amplification and onward disease transmission.”
The study was funded by USAID and Janssen Research and Development. Dr. Goodall has disclosed no relevant financial relationships. Dr. Dheda has received funding from the EU and the South African Medical Research Council for studies related to the diagnosis or management of drug-resistant tuberculosis. Dr. Lange is supported by the German Center for Infection Research and has received funding from the European Commission for studies on the development of novel antituberculosis medicines and for studies related to novel diagnostics of tuberculosis; consulting fees from INSMED; speaker’s fees from INSMED, GILEAD, and Janssen; and is a member of the data safety board of trials from Medicines sans Frontiers, all of which are unrelated to the current study.

New genetic variant linked to maturity-onset diabetes of the young
A newly discovered genetic variant that is associated with type 2 diabetes (T2D) is responsible for almost 7% of all diabetes cases in Greenland, according to a whole-genome sequencing analysis of 448 Greenlandic Inuit individuals.
The variant, identified as c.1108G>T, “has the largest population impact of any previously reported variant” within the HNF1A gene – a gene that can cause maturity-onset diabetes of the young (MODY), reported senior author Torben Hansen, MD, PhD, of the University of Copenhagen, and colleagues in The Lancet Regional Health–Europe. The c.1108G>T variant does not cause MODY, but other variants within the HNF1A gene do. However, carriers of this variant, which is present in 1.9% of the Greenlandic Inuit population and has not been found elsewhere, have normal insulin sensitivity, but decreased beta-cell function and a more than fourfold risk of developing type 2 diabetes. “This adds to a previous discovery that about 11% of all diabetes in Greenlandic Inuit is explained by a mutation in the TBC1D4 variant,” Dr. Hansen told this publication. “Thus 1 in 5 patients diagnosed with type 2 diabetes in Greenland have a specific mutation explaining their diabetes. In European populations only about 1%-2% of patients diagnosed with type 2 diabetes have a known genetic etiology.”
The finding “provides new avenues to subgroup patients, detect diabetes in family members, and pursue precision treatment trials,” noted the authors, although they acknowledged that treatment choices for individuals with this variant still need to be explored. “We know from HNF1A-mutation carriers with European ancestry that they benefit from sulfonylurea treatment,” said Dr. Hansen. “However, we have not yet done treatment studies in Inuit.” The investigators noted that “it is not always the case that variants in HNF1A result in an increased insulin secretory response to sulfonylurea. ... Whether carriers of the c.1108G>T variant could benefit from treatment with sulfonylurea should be pursued within the context of a randomized clinical trial establishing both short- and long-term efficacy of sulfonylurea in these patients.”
A total of 4,497 study participants were randomly sampled from two cross-sectional cohorts in an adult Greenlandic population health survey. Among 448 participants who had whole genome sequencing, 14 known MODY genes were screened for both previously identified as well as novel variants. This identified the c.1108G>T variant, which was then genotyped in the full cohort in order to estimate an allele frequency of 1.3% in the general Greenlandic population, and 1.9% in the Inuit component. The variant was not found in genome sequences of other populations.
The researchers then tested the association of the variant with T2D and showed strong association with T2D (odds ratio, 4.35) and higher hemoglobin A1c levels.
“This is very well-conducted and exciting research that highlights the importance of studying the genetics of diverse populations,” said Miriam Udler, MD, PhD, director of the Massachusetts General Diabetes Genetics Clinic, and assistant professor at Harvard University, both in Boston. “This manuscript builds on prior work from the researchers identifying another genetic variant specific to the Greenlandic Inuit population in the gene TBC1D4,” she added. “About 3.8% of people in this population carry two copies of the TBC1D4 variant and have about a 10-fold increased risk of diabetes. Together the two variants affect 18% of Greenlanders with diabetes.”
With its fourfold increased risk of diabetes, the new variant falls into “an ever-growing category” of “intermediate risk” genetic variants, explained Dr. Udler – “meaning that they have a large impact on diabetes risk, but cannot fully predict whether someone will get diabetes. The contribution of additional risk factors is particularly important for ‘intermediate risk’ genetic variants,” she added. “Thus, clinically, we can tell patients who have variants such as HNF1A c.1108>T that they are at substantial increased risk of diabetes, but that many will not develop diabetes. And for those who do develop diabetes, we are not yet able to advise on particular therapeutic strategies.”
Still, she emphasized, the importance of studying diverse populations with specific genetic risk factors is the end-goal of precision medicine. “An active area of research is determining whether and how to return such information about ‘intermediate risk’ variants to patients who get clinical genetic testing for diabetes, since typically only variants that are very high risk ... are returned in clinical testing reports.” Dr. Udler added that “many more such “intermediate risk’ variants likely exist in all populations, but have yet to be characterized because they are less common than HNF1A c.1108>T; however, ongoing worldwide efforts to increase the sample sizes of human genetic studies will facilitate such discovery.”
The study was funded by Novo Nordisk Foundation, Independent Research Fund Denmark, and Karen Elise Jensen’s Foundation. Dr. Hansen and Dr. Udler had no disclosures.

Still, she emphasized, the importance of studying diverse populations with specific genetic risk factors is the end-goal of precision medicine. “An active area of research is determining whether and how to return such information about ‘intermediate risk’ variants to patients who get clinical genetic testing for diabetes, since typically only variants that are very high risk ... are returned in clinical testing reports.” Dr. Udler added that “many more such “intermediate risk’ variants likely exist in all populations, but have yet to be characterized because they are less common than HNF1A c.1108>T; however, ongoing worldwide efforts to increase the sample sizes of human genetic studies will facilitate such discovery.”
The study was funded by Novo Nordisk Foundation, Independent Research Fund Denmark, and Karen Elise Jensen’s Foundation. Dr. Hansen and Dr. Udler had no disclosures.

Study finds chronic jet lag–like body clocks in people with HIV
, according to findings that suggest both a possible mechanism for increased comorbidities in PLWH and potential solutions.
“It is very well known that sleep problems are common in people living with HIV, and many different reasons for this have been proposed,” coauthor Malcolm von Schantz, PhD, professor of chronobiology at Northumbria University in Newcastle upon Tyne, England, said in an interview. “But the novelty of our findings is the observation of delayed circadian rhythms.”
The mistimed circadian phase in PLWH is linked to later sleep onset and earlier waking and has “important potential implications” for the health and well-being of PLWH, wrote senior author Karine Scheuermaier, MD, from the University of the Witwatersrand, in Johannesburg, South Africa, and coauthors.
Until now, research on sleep in HIV has focused primarily on its homeostatic components, such as sleep duration and staging, rather than on circadian-related aspects, they noted.
“If the lifestyle‐independent circadian misalignment observed in the current study is confirmed to be a constant feature of chronic HIV infection, then it may be a mediator both of poorer sleep health and of poorer physical health in PLWH, which could potentially be alleviated through light therapy or chronobiotic medication or supplements,” they suggested.
HIV endemic in study population
The study analyzed a random sample of 187 participants (36 with HIV and 151 without) in the HAALSI (Health and Ageing in Africa: A Longitudinal Study of an INDEPTH Community in South Africa) study, which is part of the Agincourt Health and Socio-demographic Surveillance System.
The study population ranged in age from 45 to 93 years, with an average age of 60.6 years in the HIV-positive group and 68.2 years in the HIV-negative group. Demographic data, Pittsburgh Sleep Quality Index score, and valid actigraphy (measured with an accelerometer for 14 consecutive days) were available for 172 participants (18% with HIV). A subgroup of 51 participants (22% with HIV) also had valid dim light melatonin onset (DLMO) data, a sensitive measure of the internal circadian clock. DLMO was measured for a minimum of 5 consecutive days with hourly saliva sampling between 5 p.m. and 11 p.m. while sitting in a dimly lit room.
In 36 participants (16% with HIV) with both valid actigraphy and DLMO data, circadian phase angle of entrainment was calculated by subtracting DLMO time from habitual sleep-onset time obtained from actigraphy.
After adjustment for age and sex, the study found a slightly later sleep onset (adjusted average delay of 10 minutes), earlier awakening (adjusted average advance of 10 minutes), and shorter sleep duration in PLWH compared with HIV-negative participants.
At the same time, melatonin production in PLWH started more than an hour later on average than in HIV-negative participants, “with half of the HIV+ group having an earlier habitual sleep onset than DLMO time” the authors wrote. In a subgroup of 36 participants with both valid actigraphy and DLMO data, the median circadian phase angle of entrainment was smaller in PLWH (–6 minutes vs. +1 hour 25 minutes in the HIV-negative group).
“Collectively, our data suggest that the sleep phase occurred earlier than what would be biologically optimal among the HIV+ participants,” they added.
Asynchrony between bedtime and circadian time
“Ideally, with this delayed timing of circadian phase, they should have delayed their sleep phase (sleep timing) by an equal amount to be sleeping at their optimal biological time,” Dr. Scheuermaier explained. “Their sleep onset was delayed by 12 minutes (statistically significant but biologically not that much) while their circadian phase was delayed by more than an hour.”
Possible consequences of a smaller phase angle of entrainment include difficulty in initiating and maintaining sleep, the authors wrote. “The shorter, potentially mistimed sleep relative to the endogenous circadian cycle observed in this study provides objectively measured evidence supporting the abundant previous subjective reports of poor sleep quality and insomnia in PLWH.”
They noted that a strength of their study is that participants were recruited from rural South Africa, where HIV prevalence is not confined to the so-called “high-risk” groups of gay men, other men who have sex with men, people who inject drugs, and sex workers.
“Behavioral factors associated with belonging to one or more of these groups would be strong potential confounders for studies of sleep and circadian phase,” they explained. “By contrast, in rural southern Africa, the epidemic has been less demographically discriminating ... There are no notable differences in lifestyle between the HIV– and HIV+ individuals in this study. The members of this aging population are mostly beyond retirement age, living quiet, rural lives supported by government remittances and subsistence farming.”
Direct evidence warrants further study
The study is “unique” in that it provides “the first direct evidence for potential circadian disturbances in PWLH,” agreed Peng Li, PhD, who was not involved in the study.
“The assessment of dim light melatonin onset in PLWH is a strength of the study; together with actigraphy-based sleep onset assessment, it provides a measure for the phase angle of entrainment,” said Dr. Li, who is research director of the medical biodynamics program, division of sleep and circadian disorders, Brigham and Women’s Hospital, Boston.
But actigraphy has limitations that affect the interpretation of the results, he told this news organization.
“Without the help of sleep diaries, low specificity in assessing sleep using actigraphy has been consistently reported,” he said. “The low specificity means a significant overestimation of sleep. This lowers the value of the reported sleep readouts and limits the validity of sleep onset estimation, especially considering that differences in sleep measures between the two groups are relatively small, compromising the clinical meaning.”
Additionally, he explained that it’s not clear whether sleep onset in the study participants was spontaneous or was “forced” to accommodate routines. “This is a limitation in field study as compared with in-lab studies,” he said.
Dr. Li also pointed to the small sample size and younger age of PLWH, suggesting the study might have benefited from a matched design. Finally, he said the study did not examine gender differences.
“In the general population, it is known that females usually have advanced circadian phase compared to males. ... More rigorous design and analyses based on sex/gender especially in this often-marginalized population are warranted to better inform HIV-specific or general clinical guidelines.”
The study was supported by the Academy of Medical Sciences. The authors did not mention any competing interests. Dr. Li reported grant support from the BrightFocus Foundation. The study is not directly related to this paper. He also receives grant support from the NIH through a Departmental Award, Harvard University Center for AIDS Research and a Pilot Project, HIV and Aging Research Consortium. The projects are on circadian disturbances and cognitive performance in PLWH.

New statement guides the diagnosis of pediatric anxiety
The Canadian Paediatric Society (CPS) has issued a position statement on the diagnosis of anxiety disorders in children and youth. The organization aims to “offer evidence-informed guidance to support pediatric health care providers making decisions around the care of children and adolescents with these conditions.”
“It’s been a long time coming,” lead author Benjamin Klein, MD, assistant clinical professor of pediatrics at McMaster University, Hamilton, Ont., told this news organization. The target audience for the documents includes community pediatricians, subspecialists, family doctors, and nurse practitioners. “There was a great demand from that audience for a position statement, for guidance, obviously in the backdrop of rising child and adolescent mental health incidence over the years and of course COVID,” said Dr. Klein.
The statement was published on the CPS website.
‘A comprehensive approach’
Although many other guidelines on this topic are available, it was important to have a Canadian document, said Dr. Klein. “Obviously, there’s going to be a great deal of overlap with European or American guidelines, but it’s just kind of assumed that people want specifically Canadian content. ... Physicians want to know that they’re practicing within a standard of care in Canada.” Dr. Klein is medical director of the Lansdowne Children’s Centre, Brantford, Ont., which provides help for children with communication, developmental, and physical special needs across Ontario.
Anxiety disorders are the most common mental disorders among children and adolescents in Canada, according to the position statement. The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) groups these disorders into separation anxiety disorder, selective mutism, specific phobia, social anxiety disorder (social phobia), panic disorder, agoraphobia, and generalized anxiety disorder.
Distinguishing normal, age-appropriate anxiety from anxiety disorder, while also recognizing other comorbidities, is complicated, said Dr. Klein. “Anxiety is one possible diagnosis or feature, and children with mental health and developmental problems often present with a number of problems. Anxiety may be one of them, but if it’s one of them, it may not be the main driver. So, a comprehensive approach is needed ... combining the medical model with biopsychosocial thinking to give a better picture of anxiety in the context of anything else that may be contributing to a presentation.”
The statement outlines recommendations for anxiety assessment, starting with a screening questionnaire such as the Screen for Child Anxiety Related Disorders (SCARED), which is completed by parents and children, to assess symptom severity. Standardized measures for medical, mental health, and developmental histories are available on the CPS website.
The document next recommends an interview about presenting concerns (such as sleep problems or school difficulties), inciting events, and parent-child interactions. The process includes confidential, nonjudgmental interviews with adolescents using a history-taking tool such as HEEADSSS (Home, Education/Employment, Eating, Activities, Drugs, Sexuality, Suicide/Mental Health, and Safety).
“The diagnosis and treatment of anxiety disorders kind of sounds simple if you just read about it as an isolated thing, but the reality is ... there’s no MRI. It’s detective work,” said Dr. Klein. Clinicians must distinguish between normal anxiety, situational anxiety, and specific anxiety disorder, he added. He usually allows 90 minutes for an anxiety assessment, partly to gain the patient’s trust. “These are sensitive issues. It’s common that people don’t trust a diagnosis if you haven’t spent enough time with them. That relational care piece just needs to be there, or people aren’t going to buy in.”
The CPS position statement was reviewed and endorsed by the Canadian Academy of Child and Adolescent Psychiatry.
Methodology unclear
Joanna Henderson, MD, professor of psychiatry at the University of Toronto and director of the Margaret and Wallace McCain Centre for Child, Youth, and Family Mental Health at the Centre for Addiction and Mental Health, Toronto, said that the guidelines have been released at an important time. “Conversations about mental health have become more common, and many children, youth, and families are reaching out for support. It is essential that health care professionals be equipped with accessible information about practices to provide appropriate care. These guidelines support that vision.”
It would be helpful to know more about the methods used to arrive at the recommendations, however, said Dr. Henderson. “It is critical that health care providers be guided by evidence-based guidelines that adhere to criteria for establishing high-quality guidelines. Because the authors did not provide information about their methods, I am not able to provide a comment about the quality of their guidelines. There are established approaches for evaluating quality, and I would encourage the authors to publish as a supplement to this article their methods, including in reference to the Appraisal of Guidelines for Research and Evaluation (AGREE II) checklist.”
In the absence of readily available information about methods, she said, “clinicians are encouraged to use guidelines from sources that provide information about the guideline development process and include quality appraisal,” such as the UK National Institute for Health and Care Excellence, which is “generally recognized as a reputable source for high-quality practice guidelines.”
Responding to this concern, Dr. Klein said, “There is no specific evidence base for diagnosis. That robust science doesn’t exist. No one has done randomized controlled trials of different methods of diagnosing kids with anxiety. We looked at other position statements, we looked at textbooks, and obviously we drew from our own clinical experience, so it comes from clinical judgment and expert opinion.”
Dr. Henderson also noted that in the future “it will be important to contextualize the recommendations by highlighting the importance of cultural competence in conducting assessments and providing treatment.” Moreover, current evidence can be expanded through the incorporation of diverse cultural and racial perspectives, experiences, and data, she added.
Health service providers should reflect on their own potential biases, which can influence clinician-patient interactions, Dr. Henderson continued. It also is important to consider biases in the evidence, which influence practice. Clinicians should also consider how their recommendations fit with patients’ “cultural and race-based experiences, beliefs, and practices.”
No source of funding for the position statement was reported. Dr. Klein and Dr. Henderson had disclosed no relevant financial relationships.

The process includes confidential, nonjudgmental interviews with adolescents using a history-taking tool such as HEEADSSS (Home, Education/Employment, Eating, Activities, Drugs, Sexuality, Suicide/Mental Health, and Safety).
“The diagnosis and treatment of anxiety disorders kind of sounds simple if you just read about it as an isolated thing, but the reality is ... there’s no MRI. It’s detective work,” said Dr. Klein. Clinicians must distinguish between normal anxiety, situational anxiety, and specific anxiety disorder, he added. He usually allows 90 minutes for an anxiety assessment, partly to gain the patient’s trust. “These are sensitive issues. It’s common that people don’t trust a diagnosis if you haven’t spent enough time with them. That relational care piece just needs to be there, or people aren’t going to buy in.”
The CPS position statement was reviewed and endorsed by the Canadian Academy of Child and Adolescent Psychiatry.
Methodology unclear
Joanna Henderson, MD, professor of psychiatry at the University of Toronto and director of the Margaret and Wallace McCain Centre for Child, Youth, and Family Mental Health at the Centre for Addiction and Mental Health, Toronto, said that the guidelines have been released at an important time. “Conversations about mental health have become more common, and many children, youth, and families are reaching out for support. It is essential that health care professionals be equipped with accessible information about practices to provide appropriate care. These guidelines support that vision.”
It would be helpful to know more about the methods used to arrive at the recommendations, however, said Dr. Henderson. “It is critical that health care providers be guided by evidence-based guidelines that adhere to criteria for establishing high-quality guidelines. Because the authors did not provide information about their methods, I am not able to provide a comment about the quality of their guidelines. There are established approaches for evaluating quality, and I would encourage the authors to publish as a supplement to this article their methods, including in reference to the Appraisal of Guidelines for Research and Evaluation (AGREE II) checklist.”
In the absence of readily available information about methods, she said, “clinicians are encouraged to use guidelines from sources that provide information about the guideline development process and include quality appraisal,” such as the UK National Institute for Health and Care Excellence, which is “generally recognized as a reputable source for high-quality practice guidelines.”
Responding to this concern, Dr. Klein said, “There is no specific evidence base for diagnosis. That robust science doesn’t exist. No one has done randomized controlled trials of different methods of diagnosing kids with anxiety. We looked at other position statements, we looked at textbooks, and obviously we drew from our own clinical experience, so it comes from clinical judgment and expert opinion.”
Dr. Henderson also noted that in the future “it will be important to contextualize the recommendations by highlighting the importance of cultural competence in conducting assessments and providing treatment.” Moreover, current evidence can be expanded through the incorporation of diverse cultural and racial perspectives, experiences, and data, she added.
Health service providers should reflect on their own potential biases, which can influence clinician-patient interactions, Dr. Henderson continued. It also is important to consider biases in the evidence, which influence practice. Clinicians should also consider how their recommendations fit with patients’ “cultural and race-based experiences, beliefs, and practices.”
No source of funding for the position statement was reported. Dr. Klein and Dr. Henderson had disclosed no relevant financial relationships.

Rapid action or sustained effect? Methotrexate vs. ciclosporin for pediatric AD
MONTREAL – in the TREAT study, investigators reported at the annual meeting of the International Society of Atopic Dermatitis.
The findings are important, since many regulatory bodies require patients to have tried such first-line conventional systemic therapies before moving on to novel therapeutics, explained Carsten Flohr, MD, PhD, research and development lead at St John’s Institute of Dermatology, Guy’s and St Thomas’ NHS Foundation Trust London.
“We don’t really have much pediatric trial data; very often the pediatric data that we have is buried in adult trials and when it comes to an adequately powered randomized controlled trial with conventional systemic medication in pediatric patients, we don’t have one – so we’re lacking that gold standard,” said Dr. Flohr, chair in dermatology and population health sciences at King’s College London.
In the TREAT trial, 103 patients with AD (mean age, 10 years) who had not responded to topical treatment, were randomly assigned to oral ciclosporin (4 mg/kg daily) or methotrexate (0.4 mg/kg weekly) for 36 weeks and then followed for another 24 weeks off therapy for the co-primary outcomes of change in objective Scoring Atopic Dermatitis (o-SCORAD) at 12 weeks, as well as time to first significant flare after treatment cessation, defined as returning to baseline o-SCORAD, or restarting a systemic treatment.
Secondary outcomes included disease severity and quality of life (QOL) measures, as well as safety. At baseline, the mean o-SCORAD was 46.81, with mean Eczema Area and Severity Index (EASI) and Patient Oriented Eczema Measure (POEM) scores of 28.05 and 20.62 respectively. The mean Children’s Dermatology Life Quality Index (CDLQI) score was 14.96.
Looking at change in eczema severity measured by o-SCORAD at 12 weeks, ciclosporin was superior to methotrexate, with a mean difference in o-SCORAD change of -5.69 (P =.01). For the co-primary endpoint of time to first significant flare during the 24 weeks after treatment cessation, “there was a trend toward more flare activity in the ciclosporin group, although with a hazard ratio of 1.55, this was statistically not significant,” Dr. Flohr said.
On a graph showing mean EASI scores from baseline through the 60-week study period, Dr. Flohr explained how the score first dropped more precipitously in patients treated with ciclosporin compared with those treated with methotrexate, reaching a statistically significant difference between the groups by 12 weeks (–3.13, P = .0145).
However, after that time, while the EASI score among those on methotrexate continued to drop, the ciclosporin score evened out, so that by 20 weeks, methotrexate EASI scores were better, and remained so until the end of treatment and further, out to 60 weeks (mean difference -6.36, P < .001). “The most interesting bit of this graph is [that] the curve is pointing downwards for methotrexate up to the 9-month point, suggesting these people had not reached their full therapeutic potential yet, whereas if you’re on ciclosporin you plateau and there’s not much additional improvement, if at all, and then people [on ciclosporin] start going up in their disease activity off therapy,” he said.
The same pattern was seen with all the other outcome measures, including o-SCORAD and POEM.
Quality of life significantly improved by about 8 points in both treatment groups, with no significant differences between groups, and this improvement was sustained through the 24 weeks following cessation of therapy. However, during this treatment-free phase, patients on methotrexate had fewer parent-reported flares compared with those on ciclosporin (mean 6.19 vs 5.40 flares, P =.0251), although there was no difference between groups in time to first flare.
Describing the treatment safety as “overall reassuring,” Dr. Flohr said there were slightly more nonserious adverse events in the methotrexate arm (407 vs. 369), with nausea occurring more often in this group (43.1% vs. 17.6%).
“I think we were seeing this clinically, but to see it in a clinical trial gives us more confidence in discussing with parents,” said session moderator Melinda Gooderham, MD, assistant professor at Queens University, Kingston, Ont., and medical director at the SKiN Centre for Dermatology in Peterborough.
What she also took away from the study was safety of these treatments. “The discontinuation rate was not different with either drug, so it’s not like ciclosporin works fast but all these people have problems and discontinue,” Dr. Gooderham told this news organization. “That’s also reassuring.”
Asked which treatment she prefers, Dr. Gooderham, a consultant physician at Peterborough Regional Health Centre, picked methotrexate “because of the lasting effect. But there are times when you may need more rapid control ... where I might choose ciclosporin first, but for me it’s maybe 90% methotrexate first, 10% ciclosporin.”
Dr. Flohr and Dr. Gooderham report no relevant financial relationships. The study was funded by the National Institute for Health and Care Research.

Online support tool improves AD self-management
MONTREAL – for up to 1 year, according to two randomized controlled trials presented at the annual meeting of the International Society of Atopic Dermatitis.
The intervention, directed either at parents of children with AD or young adults with AD, “is very low cost, evidence based, easily accessible, and free from possible commercial bias,” said investigator Kim Thomas, MD, professor of applied dermatology research and codirector of the Centre of Evidence Based Dermatology, faculty of medicine & health sciences, University of Nottingham (England).
The main focus of the intervention, along with general education, is “getting control” of the condition with flare-control creams and “keeping control” with regular emollient use.
Efficacy of the intervention, available free online, was compared with “usual eczema care” in 340 parents of children with AD up to age 12 and 337 young patients with AD aged 13-25. Participants were randomized to the intervention plus usual care or usual care alone. The primary outcome was the Patient-Oriented Eczema Measure(POEM) at 24 weeks, with a further measurement at 52 weeks.
In the parent group, about half were women and 83% were White, and the median age of their children was 4 years. About 50% of parents had a university degree, making them “possibly better educated than we might want our target audience for this type of intervention,” Dr. Thomas commented. Most of the children had moderate AD.
In the young patient group, the mean age was 19 years, more than three-quarters were female, 83% were White, and most had moderate AD.
At 24 weeks, both intervention groups had improved POEM scores, compared with controls, with a mean difference of 1.5 points in the parent group (P = .002) and 1.7 points in the young patient group (P = .04). “A small difference, but statistically significant and sustained,” Dr. Thomas said, adding that this difference was sustained up to 52 weeks.
In terms of mechanism of action, a secondary outcome looked at the concept of enablement, “which again, seemed to be improved in the intervention group, which suggests it’s something to do with being able to understand and cope with their disease better,” she said. The tool is targeted to “people who wouldn’t normally get to a dermatologist and certainly wouldn’t get access to group interventions.”
An additional aim of the intervention was “to provide a single, consistent message received from every point of contact that people might engage with ... [from] community doctors, pharmacists, dermatologists, and importantly, eczema charities all signposting [the intervention] and sharing a consistent message.”
While the intervention is free and available to patients anywhere, Dr. Thomas emphasized that it is tailored to the U.K. health care system. “If people would like to get in touch and help work with us to maybe adapt it slightly to make it more suitable for your own health care systems, that’s something we’d be very happy to look at with you.”
Asked for comment, Natalie Cunningham, MD, panel moderator, was lukewarm about the tool. “It can be a supplement, but you can never replace the one-on-one patient–health care provider interaction,” she told this news organization. “That could be provided by a nondermatologist and supplemented by an online component,” said Dr. Cunningham, from the Izaak Walton Killam Hospital for Children in Halifax, N.S.
“First-line treatment for eczema, no matter what kind of eczema, is topical steroids, and that is something that requires a lot of education – and something you want to do one on one in person because everyone comes to it with a different experience, baggage, or understanding,” she said. “We need to figure out what the barrier is so that you can do the right education.”
In addition, with systemic AD therapies currently approved for children, parents and young patients need to be able to advocate for specialist care to access these medications, she noted.
Dr. Thomas and Dr. Cunningham reported no relevant financial relationships.

Plant-based diet cut hot flashes 78%: WAVS study
Women eating a reduced-fat vegan diet combined with a daily serving of soybeans experienced a 78% reduction in frequency of menopausal hot flashes over 12 weeks, in a small, nonblinded, randomized-controlled trial.
“We do not fully understand yet why this combination works, but it seems that these three elements are key: avoiding animal products, reducing fat, and adding a serving of soybeans,” lead researcher Neal Barnard, MD, explained in a press release. “These new results suggest that a diet change should be considered as a first-line treatment for troublesome vasomotor symptoms, including night sweats and hot flashes,” added Dr. Barnard, who is president of the Physicians Committee for Responsible Medicine, and adjunct professor at George Washington University, Washington. 
But, while “the findings from this very small study complement everything we know about the benefits of an excellent diet and the health benefits of soy,” they should be interpreted with some caution, commented Susan Reed, MD, president of the North American Menopause Society, and associate program director of the women’s reproductive research program at the University of Washington, Seattle.
For the trial, called WAVS (Women’s Study for the Alleviation of Vasomotor Symptoms), the researchers randomized 84 postmenopausal women with at least two moderate to severe hot flashes daily to either the intervention or usual diet, with a total of 71 subjects completing the 12-week study, published in Menopause. Criteria for exclusion included any cause of vasomotor symptoms other than natural menopause, current use of a low-fat, vegan diet that includes daily soy products, soy allergy, and body mass index < 18.5 kg/m2.
Participants in the intervention group were asked to avoid animal-derived foods, minimize their use of oils and fatty foods such as nuts and avocados, and include half a cup (86 g) of cooked soybeans daily in their diets. They were also offered 1-hour virtual group meetings each week, in which a registered dietitian or research staff provided information on food preparation and managing common dietary challenges.
Control group participants were asked to continue their usual diets and attend four 1-hour group sessions.
At baseline and then after the 12-week study period, dietary intake was self-recorded for 2 weekdays and 1 weekend day, hot flash frequency and severity was recorded for 1 week using a mobile app, and the effect of menopausal symptoms on quality of life was measured using the vasomotor, psychosocial, physical, and sexual domains of the Menopause-Specific Quality of Life (MENQOL) questionnaire.
Equol production was also assessed in a subset of 15 intervention and 12 control participants who had urinary isoflavone concentrations measured after eating half a cup (86 g) of soybeans twice daily for 3 days. This was based on the theory that diets such as the intervention in this study “seem to foster the growth of gut bacteria capable of converting daidzein to equol,” noted the authors. The ability to produce equol is detected more frequently in individuals following vegetarian diets than in omnivores and … has been proposed as a factor in soy’s apparent health benefits.”
The study found that total hot flash frequency decreased by 78% in the intervention group (P < .001) and 39% (P < .001) in the control group (between-group P = .003), and moderate to severe hot flashes decreased by 88% versus 34%, respectively (from 5.0 to 0.6 per day, P < .001 vs. from 4.4 to 2.9 per day, P < .001; between-group P < .001). Among participants with at least seven moderate to severe hot flashes per day at baseline, moderate to severe hot flashes decreased by 93% (from 10.6 to 0.7 per day) in the intervention group (P < .001) and 36% (from 9.0 to 5.8 per day) in the control group (P = .01, between-group P < .001). The changes in hot flashes were paralleled by changes in the MENQOL findings, with significant between-group differences in the vasomotor (P = 0.004), physical (P = 0.01), and sexual (P = 0.03) domains.
Changes in frequency of severe hot flashes correlated directly with changes in fat intake, and inversely with changes in carbohydrate and fiber intake, such that “the greater the reduction in fat intake and the greater the increases in carbohydrate and fiber consumption, the greater the reduction in severe hot flashes,” noted the researchers. Mean body weight also decreased by 3.6 kg in the intervention group and 0.2 kg in the control group (P < .001). “Equol-production status had no apparent effect on hot flashes,” they added.
The study is the second phase of WAVS, which comprises two parts, the first of which showed similar results, but was conducted in the fall, raising questions about whether cooler temperatures were partly responsible for the results. Phase 2 of WAVS enrolled participants in the spring “ruling out the effect of outside temperature,” noted the authors.
“Eating a healthy diet at midlife is so important for long-term health and a sense of well-being for peri- and postmenopausal women,” said Dr Reed, but she urged caution in interpreting the findings. “This was an unblinded study,” she told this news organization. “Women were recruited to this study anticipating that they would be in a study on a soy diet. Individuals who sign up for a study are hoping for benefit from the intervention. The controls who don’t get the soy diet are often disappointed, so there is no benefit from a nonblinded control arm for their hot flashes. And that is exactly what we saw here. Blinded studies can hide what you are getting, so everyone in the study (intervention and controls) has the same anticipated benefit. But you cannot blind a soy diet.”
Dr. Reed also noted that, while the biologic mechanism of benefit should be equol production, this was not shown – given that both equol producers and nonproducers in the soy intervention reported marked symptom reduction.
“Only prior studies with estrogen interventions have observed reductions of hot flashes of the amount reported here,” she concluded. “Hopefully future large studies will clarify the role of soy diet for decreasing hot flashes.”

Women eating a reduced-fat vegan diet combined with a daily serving of soybeans experienced a 78% reduction in frequency of menopausal hot flashes over 12 weeks, in a small, nonblinded, randomized-controlled trial.
“We do not fully understand yet why this combination works, but it seems that these three elements are key: avoiding animal products, reducing fat, and adding a serving of soybeans,” lead researcher Neal Barnard, MD, explained in a press release. “These new results suggest that a diet change should be considered as a first-line treatment for troublesome vasomotor symptoms, including night sweats and hot flashes,” added Dr. Barnard, who is president of the Physicians Committee for Responsible Medicine, and adjunct professor at George Washington University, Washington.
But, while “the findings from this very small study complement everything we know about the benefits of an excellent diet and the health benefits of soy,” they should be interpreted with some caution, commented Susan Reed, MD, president of the North American Menopause Society, and associate program director of the women’s reproductive research program at the University of Washington, Seattle.
For the trial, called WAVS (Women’s Study for the Alleviation of Vasomotor Symptoms), the researchers randomized 84 postmenopausal women with at least two moderate to severe hot flashes daily to either the intervention or usual diet, with a total of 71 subjects completing the 12-week study, published in Menopause. Criteria for exclusion included any cause of vasomotor symptoms other than natural menopause, current use of a low-fat, vegan diet that includes daily soy products, soy allergy, and body mass index < 18.5 kg/m2.
Participants in the intervention group were asked to avoid animal-derived foods, minimize their use of oils and fatty foods such as nuts and avocados, and include half a cup (86 g) of cooked soybeans daily in their diets. They were also offered 1-hour virtual group meetings each week, in which a registered dietitian or research staff provided information on food preparation and managing common dietary challenges.
Control group participants were asked to continue their usual diets and attend four 1-hour group sessions.
At baseline and then after the 12-week study period, dietary intake was self-recorded for 2 weekdays and 1 weekend day, hot flash frequency and severity was recorded for 1 week using a mobile app, and the effect of menopausal symptoms on quality of life was measured using the vasomotor, psychosocial, physical, and sexual domains of the Menopause-Specific Quality of Life (MENQOL) questionnaire.
Equol production was also assessed in a subset of 15 intervention and 12 control participants who had urinary isoflavone concentrations measured after eating half a cup (86 g) of soybeans twice daily for 3 days. This was based on the theory that diets such as the intervention in this study “seem to foster the growth of gut bacteria capable of converting daidzein to equol,” noted the authors. The ability to produce equol is detected more frequently in individuals following vegetarian diets than in omnivores and … has been proposed as a factor in soy’s apparent health benefits.”
The study found that total hot flash frequency decreased by 78% in the intervention group (P < .001) and 39% (P < .001) in the control group (between-group P = .003), and moderate to severe hot flashes decreased by 88% versus 34%, respectively (from 5.0 to 0.6 per day, P < .001 vs. from 4.4 to 2.9 per day, P < .001; between-group P < .001).

Remote assessment of atopic dermatitis is feasible with patient-provided images: Study
MONTREAL – , as well as the possibility of conducting remote clinical trials that would be less expensive and less burdensome for participants, according to investigators, who presented the study at the annual meeting of the International Society of Atopic Dermatitis.
Still, practical barriers need to be addressed, particularly the problem of image quality, noted study investigator Aviël Ragamin, MD, from the department of dermatology, Erasmus MC, University Medical Center, Rotterdam, the Netherlands.
“Good-quality images are crucial, [and] in our study, patients didn’t have any incentive to provide images because they had already received their medical consultation,” he explained. He suggested that this problem could be overcome by providing technical support for patients and compensation for trial participants.
The study included 87 children (median age, 7 years), who were assessed for AD severity at an academic outpatient clinic. The in-person visit included assessment with the Eczema Area and Severity Index (EASI) score, as well as the collection of whole-body clinical images. Parents were then asked to return home and to provide their own clinical images and self-administered EASI assessments of their child for comparison. Four raters were asked to rate all images twice and to compare in-clinic and self-administered EASI scores based on the images.
At the in-clinic visit, the median EASI score of the group was 8.8. The majority of patients had moderate (46.6%) or severe (14.8%) AD. Roughly 40% of the patients had darker skin (Fitzpatrick skin types IV–VI).
Using Spearman rank correlation of 1,534 in-clinic and 425 patient-provided images, the study found good inter- and intra-rater reliability for clinical image assessment and strong agreement between images and the in-clinic EASI scores. The top outliers in the assessment were individuals with either darker skin or significant postinflammatory hyperpigmentation, which are “the most difficult cases to rate, based on images,” Dr. Ragamin noted.
There was only moderate correlation between the in-clinic and self-administered EASI scores, with a significant number of patients either underestimating or overestimating their AD severity, he added.
Overall, the main problem with remote assessment seems to be the feasibility of patients providing images, said Dr. Ragamin. Only 36.8% of parents provided any images at all, and of these, 1 of 5 were deemed too blurry, leaving just 13 for final assessment, he explained.
“Pragmatically, it’s tricky,” said Aaron Drucker, MD, a dermatologist at Women’s College Hospital and associate professor at the University of Toronto, who was asked to comment on the study. “It takes long enough to do an EASI score in person, let alone looking through blurry pictures that take too long to load into your electronic medical record. We know it works, but when our hospital went virtual [during the COVID pandemic] ... most of my patients with chronic eczema weren’t even sending me pictures.”
Regarding the utility of remote, full-body photography in clinical practice, he said, “There’s too many feasibility hoops to jump through at this point. The most promise I see is for clinical trials, where it’s hard to get people to come in.”
Dr. Ragamin and Dr. Drucker have disclosed no relevant financial relationships.

Dupilumab-associated ocular surface disease in patients with AD: Unraveling the link
MONTREAL – , according to a study presented at the annual meeting of the International Society of Atopic Dermatitis.
In a prospective trial of 69 patients with AD starting dupilumab (Dupixent), baseline OSD was found in 91.3%, with about half of these patients reporting no symptoms, said investigator Roselie Achten, MD, from the National Expertise Center for Atopic Dermatitis at University Medical Center Utrecht, the Netherlands. Among these patients, ophthalmologic assessment revealed no OSD in 6 patients and mild OSD in 37 patients, but moderate and severe disease in 20 and 6 patients, respectively, she said, adding that 71% of the group also reported allergic conjunctivitis at baseline.
The patients enrolled in the study who started dupilumab were aged 36-38 years, with Eczema Area and Severity Index (EASI) scores of 14.7-16.5. Baseline ocular surface health was assessed with the Utrecht Ophthalmic Inflammatory and Allergic disease (UTOPIA) score. Tear fluid was collected to analyze biomarkers and dupilumab levels, and impression cytology was performed to collect conjunctival tissue cells for analysis of goblet cells. These measurements were repeated at 4 and 28 weeks after the start of therapy.
Over 28 weeks of treatment, 14.5% of patients experienced worsening of OSD, with worsening disease associated with a decline in the number of goblet cells. In addition, dupilumab treatment was associated with a significant decline in the production of Mucin5AC, suggesting a decline in function of the goblet cells. “Our hypothesis that the blocking effect of dupilumab on [interleukin-] IL-13 might lead to less goblet cells and less mucin production,” she explained.
In a subset of 48 patients, the researchers also detected significantly higher tear fluid dupilumab levels among those patients with more severe OSD, with comparable serum levels.
OSD has been reported in up to 34% of dupilumab-treated patients with AD and is the most frequently reported side-effect of this treatment, noted Dr. Achten. This side effect is not reported by other patients treated with dupilumab for other indications, she added, “suggesting that AD patients may have a predisposition to develop OSD during dupilumab treatment.”
Indeed, as recently noted by Vivian Shi, MD, from the department of dermatology, University of Arkansas for Medical Sciences, Little Rock, and colleagues, “for reasons not well understood, the incidence of conjunctivitis in dupilumab patients with asthma (0%-2.3%), chronic rhinosinusitis with nasal polyps (1.6%), or eosinophilic esophagitis (0%) is low to none; thus, patients with AD may be particularly susceptible.”
Dr. Achten said that dupilumab-treated patients with AD at her center are prescribed topical tacrolimus and ketotifen eye drops if they develop OSD.
Asked for comment, Melinda Gooderham, MD, who moderated the session, was impressed with the study. “I’d heard about the goblet cells, there were little bits of data here and there, but the tear analysis is something I hadn’t seen before. It was a nice series of experiments that pulled everything together,” she told this news organization. Dr. Gooderham, who is assistant professor at Queens University, in Kingston, Ontario, medical director at the SKiN Centre for Dermatology in Peterborough, Ontario, and consultant physician at Peterborough Regional Health Centre, said that she first began noticing dupilumab-related OSD as an early trial investigator for the drug. “When you put some patients on the drug it’s almost like tipping the balance – that little bit of mucin they’re dependent on is now reduced and it makes them more symptomatic,” she said.
Though she prescribes lubricating eye drops as prophylaxis for all her dupilumab-treated patients with AD, she recommends referring any patients who develop OSD to an ophthalmologist who is familiar with this specific side effect. “If they just see a random ophthalmologist who doesn’t know dupilumab, and doesn’t know the story around it, they could get any sort of diagnosis, or even be told to stop the medication altogether.”
The study was sponsored by Sanofi. Dr. Achten disclosed no other conflicts of interest. Dr. Gooderham is an investigator with Sanofi Genzyme for dupilumab.

Over 28 weeks of treatment, 14.5% of patients experienced worsening of OSD, with worsening disease associated with a decline in the number of goblet cells. In addition, dupilumab treatment was associated with a significant decline in the production of Mucin5AC, suggesting a decline in function of the goblet cells. “Our hypothesis that the blocking effect of dupilumab on [interleukin-] IL-13 might lead to less goblet cells and less mucin production,” she explained.
In a subset of 48 patients, the researchers also detected significantly higher tear fluid dupilumab levels among those patients with more severe OSD, with comparable serum levels.
OSD has been reported in up to 34% of dupilumab-treated patients with AD and is the most frequently reported side-effect of this treatment, noted Dr. Achten. This side effect is not reported by other patients treated with dupilumab for other indications, she added, “suggesting that AD patients may have a predisposition to develop OSD during dupilumab treatment.”
Indeed, as recently noted by Vivian Shi, MD, from the department of dermatology, University of Arkansas for Medical Sciences, Little Rock, and colleagues, “for reasons not well understood, the incidence of conjunctivitis in dupilumab patients with asthma (0%-2.3%), chronic rhinosinusitis with nasal polyps (1.6%), or eosinophilic esophagitis (0%) is low to none; thus, patients with AD may be particularly susceptible.”
Dr. Achten said that dupilumab-treated patients with AD at her center are prescribed topical tacrolimus and ketotifen eye drops if they develop OSD.
Asked for comment, Melinda Gooderham, MD, who moderated the session, was impressed with the study. “I’d heard about the goblet cells, there were little bits of data here and there, but the tear analysis is something I hadn’t seen before. It was a nice series of experiments that pulled everything together,” she told this news organization. Dr. Gooderham, who is assistant professor at Queens University, in Kingston, Ontario, medical director at the SKiN Centre for Dermatology in Peterborough, Ontario, and consultant physician at Peterborough Regional Health Centre, said that she first began noticing dupilumab-related OSD as an early trial investigator for the drug. “When you put some patients on the drug it’s almost like tipping the balance – that little bit of mucin they’re dependent on is now reduced and it makes them more symptomatic,” she said.
Though she prescribes lubricating eye drops as prophylaxis for all her dupilumab-treated patients with AD, she recommends referring any patients who develop OSD to an ophthalmologist who is familiar with this specific side effect. “If they just see a random ophthalmologist who doesn’t know dupilumab, and doesn’t know the story around it, they could get any sort of diagnosis, or even be told to stop the medication altogether.”
The study was sponsored by Sanofi. Dr. Achten disclosed no other conflicts of interest. Dr. Gooderham is an investigator with Sanofi Genzyme for dupilumab.

Evidence mounting that full-body emollients don’t prevent AD in at-risk babies
MONTREAL – , according to 5-year results of the BEEP randomized trial, reported at the annual meeting of the International Society of Atopic Dermatitis.
“So far, the science does not look convincing, and I am concerned about the possible harms,” commented senior investigator Hywel C. Williams, DSc, from the Centre of Evidence Based Dermatology, University of Nottingham (England).
The rate of AD at 2 years – the primary outcome of the BEEP trial – have already shown no benefit of either Diprobase cream or DoubleBase gel plus standard skin-care advice versus standard skin-care advice alone among 1,394 infants at high risk for developing AD. “These are children born to parents with a first-degree relative with eczema,” Dr. Williams explained.
At 2 years, 23% of the emollient group versus 25% of the control group developed eczema (adjusted relative risk, 0.95), and the parent-reported clinical skin infection rate was statistically increased (incidence rate ratio, 1.55). Despite these results, follow-up of BEEP was extended to 5 years to determine if there was a delayed benefit of emollients, both in AD prevention but also with other related disorders, he explained.
“Prevention is so much more logical than treating sick individuals with severe disease who present after a long chain of pathological events with expensive drugs. And even if you can’t primarily prevent eczema, even a small shift in the severity of distribution to the left has major public health implications,” Dr. Williams added. “And if you believe in the atopic march, then if you could prevent eczema, you might be able to prevent subsequent food allergy, asthma, and allergic rhinitis.”
The extension data was based on questionnaires at 3, 4, and 5 years documenting parental reports of doctor-diagnosed eczema and eczema severity, wheezing, allergic rhinitis, food allergy symptoms, and clinical diagnosis, as well as 5-year clinical diagnoses of asthma or allergic rhinitis. About 70% of parents returned their questionnaires at each point, showing no significant difference at 5 years for a clinical diagnosis of eczema (31% in the emollient group vs. 28% in controls), clinical diagnosis of food allergy (15% vs. 14%, respectively), or other outcomes.
“It’s a lovely hypothesis, but did we use the wrong emollients, or did we start it too late? Or should we start facing the possibility that maybe emollients really do not prevent eczema?” Dr. Williams commented, adding that he does not recommend use of emollients for AD prevention.
“There’s more research needed,” agreed panelist Eric Simpson, MD, professor of dermatology at Oregon Health & Science University, Portland, whose AD primary prevention CASCADE trial is expected to shed more light on the role of emollients in the near future. “And we can’t just ignore [another] randomized controlled trial that was done really well ... showing a positive effect,” he added, referring to the small, single-center STOP-AD trial.
“We’re always hoping, and it’s scientifically incredibly frustrating that none of this has borne out,” Aaron Drucker, MD, a dermatologist at Women’s College Hospital and associate professor at the University of Toronto, told this news organization. “It’s so appealing that emollients early in life would improve the skin barrier and then decrease likelihood of getting eczema. It’s great that there’s a new, large study from Dr. Simpson that is going to be coming out soon, so we’ll have another piece of this puzzle.”
Dr. Drucker said that although it sounds simple, there is much nuance in the question of emollients and skin barrier protection: “Who is the population that you ought to use the emollients in? What kind of emollient? How often and where? All of these things can influence potentially what the results of a trial might be. That’s where there’s still hope. I think the hope fades more and more as more evidence piles up.”
He added that although there currently is not enough evidence to recommend emollients for AD prevention, there is also not enough evidence of harm. “It’s nothing we should be afraid of,” Dr. Drucker advised.
Dr. Williams and Dr. Drucker report no relevant financial relationships.
