Severe atopic dermatitis often puts a dent in quality of life
In his role as head of the division of pediatric behavioral health at National Jewish Health, Denver, Bruce G. Bender, PhD, helps children and adults navigate the adverse effects of severe atopic dermatitis (AD) on their quality of life.
“There have been many surveys of adults with AD who report impairment of their sleep, reduced activity level, increased work absence, financial burden, emotional distress, and social avoidance,” he said at the Revolutionizing Atopic Dermatitis virtual symposium. “Similarly, children with AD or their parents report emotional distress, reduced activity, and increased school absence, social avoidance, and sleep disturbance. Families report financial burdens, conflict, particularly among the adults, social avoidance, sleep disturbance in the parents, and reduction of well-being in the siblings.”
In an effort to objectively measure sleep change in this population, Dr. Bender and colleagues recruited 14 adults with AD and 14 healthy controls who wore an ActiGraph for 1 week and completed questionnaires about sleep, itch, and quality of life. Patients with AD were awake almost twice as many minutes each night as the healthy controls (a mean of 57.3 vs. 32.3 minutes, respectively; P = .0480). Consequently, their sleep efficiency was significantly reduced based on the Pittsburgh sleep quality index (a mean of 90.6 vs. 95; P = .0305).
In another study, Dr. Bender and colleagues enrolled 20 adults with AD who underwent 2 nights of polysomnography and actigraphy. The lab was set up to measure a scratching event, which was recorded when a burst of electromyographic activity of at least 3 seconds was accompanied by a visible scratching motion. “We learned that sleep efficiency as measured by both PSG and actigraphy correlated with total body surface area and scratching index,” he said. “As we might assume, the more skin involved, the more patients scratch, the less well they sleep.”
Behavioral, neurocognitive effects
In a separate study of AD, sleep, and behavior, the researchers studied 1,041 children with asthma who were enrolled in the Childhood Asthma Management Program at eight North American sites. They used baseline parent ratings on standardized sleep and behavior rating scales and found that increased awakenings were associated with increased school absence and daytime behavior problems. “So, not only do children with AD sleep less well, but this shows up to impair their functioning during the day,” said Dr. Bender, professor of psychiatry at the University of Colorado, Denver.
In a report from Australia, researchers set out to explore the association between sleep and neurocognitive function in 21 children with eczema and 20 healthy controls. Participants underwent cognitive testing and polysomnography. The authors found that the children with eczema demonstrated lower test scores. Reduced scores were correlated with parental reports of sleep problems but not polysomnography.
In a much larger study funded by the Agency for Healthcare Research and Quality, investigators analyzed data on 354,416 children and 34,613 adults from 19 U.S. population surveys including the National Health Interview Survey 1997-2013 and the National Survey of Children’s Health 2003/4 and 2007/8. They found that AD was associated with ADHD in children (adjusted odds ratio, 1.14) and adults (aOR, 1.61). Higher odds of ADHD were found in children who had significant sleep disturbance (aOR, 16.83) and other allergic disease and asthma (aOR, 1.61).
“All of these findings show that AD can impact quality of life, especially sleep, with the result of poorer daytime functioning,” Dr. Bender said. “But those studies don’t answer this question: Are patients with AD at increased risk for psychological disorders such as depression and anxiety?”
Impact on depression, anxiety
Two systematic reviews on the topic suggest that patients with AD are twice as likely to experience depression. One was published in 2018 and the other in 2019. The 2018 review reported a little more than a twofold increase (OR, 2.19), the 2019 review a little bit less (OR, 1.71).
“At the more severe end of the depression continuum, we sometimes see suicidal ideation and suicide attempts,” Dr. Bender said. “A number of studies have asked whether these are increased in patients with AD. Quite a few studies collectively show an increased incidence of suicidal ideation. The question of suicide attempts is reflected in fewer studies. And while the result is small, it is significant. There is a significant increase reported of suicide attempts in AD patients.”
The 2018 review also found an increased incidence of anxiety in AD patients: a little more than twofold in adults (OR, 2.19) and a little less than twofold in children (OR, 1.81).
“It’s a two-way relationship between AD and psychological factors,” Dr. Bender said. “We generally think about AD – the stress that it brings, the burden that it puts on children, adults, and families. But it can work the other way around,” he said, referring to patients who have psychological problems, experience a great deal of stress, have trouble being adherent to their treatment regimen, and find it difficult to resist scratching. “The behavioral/psychological characteristics of the patient also drive the AD. It is well established that acute and chronic stress can result in a worsening of skin conditions in AD patients.”
Behavioral health interventions that have been described in the literature include cognitive therapy, stress management, biofeedback, hypnotherapy, relaxation training, mindfulness, habit reversal, and patient education – some of which have been tested in randomized trials. “All of them report a decrease in scratching as a consequence of the behavioral intervention,” Dr. Bender said.
“Other studies have been reported that look at the impact of behavioral interventions on the severity of the skin condition. Most report an improvement in the skin condition from these behavioral interventions but it’s not a perfect literature.” Critiques of these studies include the fact that there is often not enough detail about the intervention or the framework for the intervention that would allow a clinician to test an intervention in another study or actually pull that intervention into clinical practice (Cochrane Database Syst Rev. 2014 Jan 7;2014[1]:CD004054), (Int Arch Allergy Immunol.2007;144[1]:1-9).
“Some of the studies lack rigorous designs, some have sampling bias, and some have inadequate outcome measurements,” he said. “We really need additional, high-quality studies to look at what is helpful for patients with AD.”

ACR, AAD, AAO, RDS issue joint statement on safe use of hydroxychloroquine
Hydroxychloroquine can be used safely and effectively with attention to dosing, risk factors, and screening, but communication among physicians, patients, and eye care specialists is key to optimizing outcomes and preventing complications, according to a joint statement from four medical societies.
The American College of Rheumatology, American Academy of Dermatology, Rheumatologic Dermatology Society, and the American Academy of Ophthalmology have produced a statement, published in Arthritis & Rheumatology, “to emphasize points of agreement that should be recognized by practitioners in all specialties,” lead author James T. Rosenbaum, MD, of Oregon Health & Science University, Portland, and colleagues wrote.
The statement was developed by a working group that included rheumatologists, ophthalmologists, and dermatologists with records of published studies on the use of hydroxychloroquine (HCQ) and its toxicity. The statement updated elements of the 2016 American Academy of Ophthalmology guidelines for monitoring patients for retinal toxicity when using HCQ.
“The need for collaborative management has triggered this joint statement, which applies only to managing the risk of HCQ retinopathy and does not include consideration of cardiac, muscle, dermatologic, or other toxicities,” the authors noted.
The authors emphasized that HCQ plays a valuable role in controlling many rheumatic diseases, and should not be abandoned out of fear of retinopathy. However, proper dosing, recognition of risk factors, and screening strategies are essential.
Dosing data
Data on HCQ dosing and retinopathy are limited, but the authors cited a study of 2,361 rheumatic disease patients with an average HCQ dosing regimen of 5.0 mg/kg per day or less in which the toxicity risk was less than 2% for up to 10 years of use. Although data show some increase in risk with duration of use, “for a patient with a normal screening exam in a given year, the risk of developing retinopathy in the ensuing year is low (e.g., less than 5%), even after 20 years of use,” the authors said.
Risk factor recognition
“High daily [HCQ] dosage relative to body weight and cumulative dose are the primary risk factors for retinopathy,” the authors noted. Reduced renal function is an additional risk factor, and patients with renal insufficiency should be monitored and may need lower doses.
In addition, patients with a phenotype of initial parafoveal toxicity may be at increased risk for advanced disease evidenced by damage to the foveal center. “The phenotype of initial parafoveal toxicity is not universal, and in many patients (East Asians particularly) the retinal changes may appear initially along the pericentral vascular arcades,” so these patients should be screened with additional tests beyond the central macula, they emphasized.
Screening strategies
Patients should receive a baseline retinal exam within a few months of starting HCQ to rule out underlying retinal disease, according to the statement. The goal of screening is “to detect early retinopathy before a bullseye becomes visible on ophthalmoscopy, since at that severe stage the damage tends to progress even after discontinuing the medication and may eventually threaten central vision,” the authors said.
In the absence of risk factors, patients can defer screening for 5 years, but should be screened annually from 5 years and forward, they said. Examples of underlying retinal disease include “significant macular degeneration, severe diabetic retinopathy, or hereditary disorders of retinal function, but these are judgments best made by the ophthalmologist since mild and stable abnormalities that do not interfere with interpretation of critical diagnostic tests may not be a contraindication” to use of HCQ.
The consensus opinion statement has limitations, notably the shortage of data on optimum HCQ dosage and the lack of prospective studies of toxicity, including the need for studies of the impact of blood levels on toxicity and studies of pharmacogenomics to stratify risk, the authors noted.
“It is important that the drug is not stopped prematurely, but also that it is not continued in the face of definitive evidence of retinal toxicity except in some situations with unusual medical need,” they said.
“Suggestive or uncertain findings should be discussed with the patient and prescribing physician to justify further examinations, but the drug need not be stopped until evidence for retinopathy is definitive, in particular for patients with active rheumatic or cutaneous disease,” and the overall risk of retinopathy remains low if the principles described in the statement are followed, they concluded.
First author Dr. Rosenbaum disclosed financial relationships with AbbVie, UCB, Gilead, Novartis, Horizon, Roche, Eyevensys, Santen, Corvus, Affibody, Kyverna, Pfizer, Horizon, and UpToDate. Another 5 of the study’s 11 authors also disclosed relationships with multiple companies.

Peanut sublingual immunotherapy feasible and effective in toddlers
Sublingual immunotherapy for the treatment of peanut allergy is safe and effective, even in children as young as age 1 year.
In a double-blind, placebo-controlled, food challenge (DBPCFC) of some 36 peanut-allergic children (mean age 2.2 years, range 1-4 years), those who were randomly assigned to receive peanut sublingual immunotherapy (PNSLIT) showed significant desensitization compared with those who received placebo.
In addition, there was a “strong potential” for sustained unresponsiveness at 3 months for the toddlers who received the active treatment.
The findings were presented in a late breaking oral abstract session at the 2021 American Academy of Allergy, Asthma & Immunology virtual annual meeting (Abstract L2).
“A year ago, the Food and Drug Administration approved the oral agent Palforzia (peanut allergen powder) for the treatment of peanut allergy in children 4 and older, and it is a great option, but I think what we have learned over time is that this approach is not for everybody,” Edwin H. Kim, MD, director of the UNC Food Allergy Initiative, University of North Carolina at Chapel Hill, said in an interview.
Palforzia is a powder that is mixed in food like yogurt or pudding which the child then eats daily, according to a rigorous schedule. But Palforzia treatment presents some difficulties.
“Palforzia requires getting the powder dose, mixing it with food, like pudding or apple sauce, then eating it, which can take up to 30 minutes depending on age and kids’ cooperation. It tastes and smells like peanut which can cause aversion. Kids have to refrain from exercise or strenuous activity for at least 30 minutes before and after dosing and have to be observed for up to 2 hours post dose for symptoms,” Dr. Kim said.
“It’s a great drug, but the treatment could be overly difficult for certain families to be able to do, and in some cases the side effects may be more than certain patients are able or willing to handle, so there is a real urgent need for alternative approaches,” Dr. Kim said. “SLIT is several drops under the tongue, held for 2 minutes, swallowed and done.”
In the current placebo-controlled study, he and his group tested the feasibility, efficacy, and safety of the sublingual approach to peanut allergy in children age 4 years and younger.
Both groups were similar with regard to gender, race, ethnicity, atopic history, peanut skin prick test, and qualifying DBPCFC, and all children were previously allergic with positive blood and skin tests, with a positive reaction during baseline food challenge, thus proving the allergy and establishing the baseline threshold.
“We have learned from some studies, for instance the DEVIL and LEAP studies, that strongly suggest that the immune systems in younger patients may be more amenable to change, and there may be some justification for early intervention,” he said.
“Based on both of those ideas, we wanted to take our sublingual approach, which we have shown to have a pretty good efficacy in older children, and bring it down to this younger group and see if it still could have the same efficacy and also maintain what seems to be a very good safety signal.”
The researchers randomly assigned the children to receive PNSLIT at a daily maintenance dose of 4 mg peanut protein (n = 19) or to receive placebo (n = 17) for 36 months.
“There was a 5- to 6-month buildup period where the SLIT dose was increased every 1-2 weeks up to the target dose of 4 mg, and then the final dose of 4 mg was continued through to the end of the study,” Dr. Kim noted.
Over a total of 20,593 potential dosing days, the children took 91.2% of SLIT doses and 93.5% of placebo doses.
At the end of the 3-year study period, the children were challenged by DBPCFC with up to 4,333 mg of peanut protein.
Sustained unresponsiveness was assessed by an identical DBPCFC after discontinuation of the immunotherapy for 3 months.
Cumulative tolerated dose increased from a median of 143 mg to 4,443 mg in the PNSLIT group, compared with a median of 43 mg to 143 mg in the placebo group (P < .0001).
Fourteen of the children receiving PNSLIT, and none of the children receiving placebo, passed the desensitization food challenge. Twelve of the children receiving PNSLIT and two of the children receiving placebo passed the sustained unresponsiveness challenge.
Children who underwent the immunotherapy saw a decrease in their peanut skin prick test from 10 mm to 3.25 mm, compared to an increase from 11.5 mm to 12 mm with placebo (P < .0001).
The most common side effect reported was itching or irritation in the mouth. Most side effects resolved on their own, although some patients used an antihistamine. Getting children as young as 1 to hold the dose under their tongue was a challenge in some instances, but it eventually worked out, Dr. Kim said.
“It took a lot of work from the parents as well as from our research coordinators in trying to train these young kids to, first of all, allow us to put the peanut medication in the mouth and then to try as best as possible to keep it in their mouth for up to 2 minutes, but the families involved in our study were very dedicated and so we were able to get through that,” he said.
Study merits larger numbers
“Among the 36 who completed the 3 years of therapy, the authors report significant rates of desensitization among treated children compared with those receiving placebo. Furthermore, this effect was persistent for at least 3 months after stopping therapy in a subgroup of the children,” said Leonard B. Bacharier, MD, director of the Center for Pediatric Asthma, Monroe Carell Jr. Children’s Hospital at Vanderbilt, Nashville, Tenn.
“Overall, these findings suggest the promise of peanut SLIT, which should be studied in larger numbers of preschool children,” Dr. Bacharier, who was not part of the study, said in an interview.
Jonathan A. Bernstein, MD, professor of medicine, University of Cincinnati, agreed.
“It’s a well-designed study, it’s small, but it’s promising,” Dr. Bernstein, who was not involved with the study, said in an interview.
“They did show that most of the patients who got the sublingual therapy were able to get to the target dose and develop tolerance, so I think it’s promising. We know that this stuff works. This is just more data from a well-controlled study in a younger population,” he said.
“We do OIT [oral immunotherapy] and sublingual but we don’t do it in such young children in our practice. The youngest is 3 years old, because they have to understand what is going on and cooperate. If they don’t cooperate it’s not possible.”
Dr. Kim reported financial relationships with DBV Technologies, Kenota Health, Ukko, Aimmune Therapeutics, ALK, AllerGenis, Belhaven Pharma, Duke Clinical Research Institute, Nutricia, NIH/NIAID, NIH/NCCIH, NIH/Immune Tolerance Network, FARE, and the Wallace Foundation.

Sublingual immunotherapy for the treatment of peanut allergy is safe and effective, even in children as young as age 1 year.
In a double-blind, placebo-controlled, food challenge (DBPCFC) of some 36 peanut-allergic children (mean age 2.2 years, range 1-4 years), those who were randomly assigned to receive peanut sublingual immunotherapy (PNSLIT) showed significant desensitization compared with those who received placebo.
In addition, there was a “strong potential” for sustained unresponsiveness at 3 months for the toddlers who received the active treatment.
The findings were presented in a late breaking oral abstract session at the 2021 American Academy of Allergy, Asthma & Immunology virtual annual meeting (Abstract L2).
“A year ago, the Food and Drug Administration approved the oral agent Palforzia (peanut allergen powder) for the treatment of peanut allergy in children 4 and older, and it is a great option, but I think what we have learned over time is that this approach is not for everybody,” Edwin H. Kim, MD, director of the UNC Food Allergy Initiative, University of North Carolina at Chapel Hill, said in an interview.
Palforzia is a powder that is mixed in food like yogurt or pudding which the child then eats daily, according to a rigorous schedule. But Palforzia treatment presents some difficulties.
“Palforzia requires getting the powder dose, mixing it with food, like pudding or apple sauce, then eating it, which can take up to 30 minutes depending on age and kids’ cooperation. It tastes and smells like peanut which can cause aversion. Kids have to refrain from exercise or strenuous activity for at least 30 minutes before and after dosing and have to be observed for up to 2 hours post dose for symptoms,” Dr. Kim said.
“It’s a great drug, but the treatment could be overly difficult for certain families to be able to do, and in some cases the side effects may be more than certain patients are able or willing to handle, so there is a real urgent need for alternative approaches,” Dr. Kim said. “SLIT is several drops under the tongue, held for 2 minutes, swallowed and done.”
In the current placebo-controlled study, he and his group tested the feasibility, efficacy, and safety of the sublingual approach to peanut allergy in children age 4 years and younger.
Both groups were similar with regard to gender, race, ethnicity, atopic history, peanut skin prick test, and qualifying DBPCFC, and all children were previously allergic with positive blood and skin tests, with a positive reaction during baseline food challenge, thus proving the allergy and establishing the baseline threshold.

Data on atopic dermatitis risk factors are accumulating
, according to Zelma Chiesa Fuxench, MD.
This gene codes for profilaggrin, a protein, which is then cleaved to form filaggrin, which helps to organize the cytoskeleton of the skin and is an important structural component of the skin. The understanding is that patients who have filaggrin mutations tend to have earlier onset and more persistent disease, Dr. Chiesa Fuxench, of the department of dermatology at the University of Pennsylvania, Philadelphia, said during the Revolutionizing Atopic Dermatitis virtual symposium.
“Prior studies have shown that mutations in the FLG gene can confer a risk of developed AD that is two- to sevenfold with variants R501X and the 22804del4 frequently described. It is important to note that most of these findings have been described primarily in populations of European descent, with other variants being found in populations of African nation descent, and seem to be more prevalent in populations with early onset disease.”
Environmental factors
Other AD-related risk factors that have been previously described in the literature include environmental factors such as climate, diet, breastfeeding, obesity, pollution, tobacco smoke, pet ownership, and microbiome or gut microflora. “The list of culprits is ever increasing,” she said. “However, it’s important to recognize that data to support some of these associations are lacking, and oftentimes, a lot of the results are contradictory.”
As part of the International Study of Asthma and Allergies in Childhood, researchers evaluated the association between climate factors with the 12-month period prevalence rates of symptoms of atopic eczema in children. They found that patients who lived at higher latitudes and those who lived in areas where there were lower mean outdoor temperatures tended to have a higher prevalence of eczema symptoms. Worldwide, they found that symptoms of eczema were also prevalent in areas where there was lower indoor humidity.
“The authors concluded that they can’t really demonstrate a cause and effect, and that while latitude and temperature changes appear to affect the prevalence of eczema, they may do so indirectly, perhaps to changes in behavior and differences in sun exposure,” said Dr. Chiesa Fuxench, who was not involved with the study. “For example, we know that vitamin D is a protective risk factor for AD. Low vitamin D has been associated with more severe disease in some studies. We also know that UV exposure leads to the conversion of filaggrin degradation products such as trans-urocanic acid into cis-urocanic acid, which has been demonstrated to have immunosuppressive effects.”
A systematic review and meta-analysis of nine articles found small associations, which were significant, between being born in the winter (odds ratio, 1.15) and fall (OR, 1.16) and the risk of developing AD, compared with being born in the spring and summer. However, an analysis of satellite-derived data on air temperature across the United States from 1993 to 2011 found that as ambient air temperature increases, so did the risk for an ambulatory visit for AD to physicians from the National Ambulatory Medical Care Survey.
In all areas but the south, the largest number of AD visits occur in the spring. In the south, more AD visits occur in the summer. “This raises the point that we don’t really know everything when it comes to the influence of temperature and climate change on AD,” Dr. Chiesa Fuxench said.
Several maternal and neonatal risk factors for AD have been described in the literature, including the effect of prenatal exposure to antibiotics. In one large analysis, investigators assessed the association among 18-month-old children in the Danish National Birth Cohort, which included 62,560 mother-child pairs. They found that prenatal antibiotic use was associated with an increased odds of AD among children born to atopic mothers but only when used during all three trimesters (adjusted OR, 1.45). When they further stratified these analyses by type of birth (vaginal versus C-section), the association persisted in both groups, but was stronger among those delivered by C-section.
Probiotics
The role of probiotics to reduce the risk for AD has also been investigated. “We do know that probiotics could potentially be helpful, and it is often a readily available intervention,” Dr. Chiesa Fuxench said. “But the question still is how and when to supplement.”
In a systematic review and meta-analysis, researchers examined supplementation with probiotics given to breastfeeding mothers, pregnant mothers, or directly given to infants, and the risk of developing AD up to 18 months of age. They found that overall, probiotic exposure resulted in decreased risk of developing AD. In stratified analyses, the strongest association was observed for those who received probiotics during their pregnancy, during breastfeeding, and as an infant, which conferred about a 25% reduced risk.
Antibiotic exposure
What about early-life exposure to antibiotics on one’s risk for developing AD? A meta-analysis of 22 studies found that children who had been exposed to antibiotics during the first 2 years of life had an increased risk of eczema (OR, 1.26), compared with children who had not been exposed during the same period of time. “Interesting hypotheses can be generated from this study,” she said. “Perhaps future steps should focus on the impact of antibiotic exposure, the gut microbiome, and maternal risk factors for AD.”
In a separate study that supported these findings, researchers evaluated the association between the use of acid-suppressive medications and antibiotics during infancy and the development of allergic disease in early childhood. They found that exposure to either of these medications during the first six months of infancy resulted in a mild increased risk of developing AD, and concluded that they should be used during infancy only in situations of clear clinical benefit. “We should be good stewards of antibiotic use, in particular due to concern for antibiotic resistance in the population overall,” Dr. Chiesa Fuxench said.
Prevention strategies
Several AD prevention strategies have also been described in the medical literature, including the use of daily emollients during infancy. In a multicenter trial carried out in the United Kingdom, researchers tested whether daily use of emollient in the first year of life could prevent eczema in high-risk children, which was defined as having at least one first-degree relative with parent-reported eczema, allergic rhinitis, or asthma. The primary outcome was eczema at age 2 years. The researchers found no evidence to suggest that daily emollient use during the first year of life prevents eczema.
Another study, the PreventADALL trial of 2,397 infants, consisted of four treatment arms: a control group advised to follow national guidelines on infant nutrition; a skin intervention group that was asked to use skin emollients, a food intervention group with early introduction of peanut, cow’s milk, wheat, and egg, and a combined skin and food intervention. The investigators found no difference in the risk reduction of developing AD among patients who were treated with skin emollients or early complementary feeding, and concluded that these types of interventions should not be considered as interventions to prevent AD in this cohort of patients.
However, Dr. Chiesa Fuxench emphasized that emollients and moisturizers are an important part of the treatment regimen for AD patients. A Cochrane systematic review of nearly 80 randomized, controlled trials evaluating the use of emollients in eczema found that most moisturizers showed some beneficial effects in addition to active treatment, including prolonging the time to flare, reducing the number of flares, and reducing the amount of topical corticosteroids used.
For treatment, Dr. Chiesa Fuxench recommends a proactive approach focused on short-term induction therapy with intensive topical anti-inflammatories until the affected area is almost healed, followed by maintenance therapy that involves use of a long-term, low- to mid-potency steroid or a topical calcineurin inhibitor to previously affected areas. “These interventions have been shown to decrease the risk of recurrence and can shorten the treatment duration in the event of a flare,” she said.
She also favors a time-contingent approach to treating patients with AD. “As physicians, we tend to do our visits more as symptom contingent, which means when a patient is flaring. This reinforces the view that this is a difficult disease to treat, and that there is no hope,” she pointed out. But for chronic diseases, she added, “a time-contingent approach with appointments at set intervals leads to a different perception. It can result in better compliance, because skin care might be performed more regularly. It’s analogous to when you know you’re going to see the dentist so you floss more regularly the week before your appointment. There also seems to be less pressure on physicians and patients because you are seeing each other more frequently; you can talk more openly about what’s working and what’s not.”
Dr. Chiesa Fuxench reported having no disclosures relevant to her presentation.

It can result in better compliance, because skin care might be performed more regularly. It’s analogous to when you know you’re going to see the dentist so you floss more regularly the week before your appointment. There also seems to be less pressure on physicians and patients because you are seeing each other more frequently; you can talk more openly about what’s working and what’s not.”

This gene codes for profilaggrin, a protein, which is then cleaved to form filaggrin, which helps to organize the cytoskeleton of the skin and is an important structural component of the skin. The understanding is that patients who have filaggrin mutations tend to have earlier onset and more persistent disease, Dr. Chiesa Fuxench, of the department of dermatology at the University of Pennsylvania, Philadelphia, said during the Revolutionizing Atopic Dermatitis virtual symposium.
“Prior studies have shown that mutations in the FLG gene can confer a risk of developed AD that is two- to sevenfold with variants R501X and the 22804del4 frequently described. It is important to note that most of these findings have been described primarily in populations of European descent, with other variants being found in populations of African nation descent, and seem to be more prevalent in populations with early onset disease.”
Environmental factors
Other AD-related risk factors that have been previously described in the literature include environmental factors such as climate, diet, breastfeeding, obesity, pollution, tobacco smoke, pet ownership, and microbiome or gut microflora. “The list of culprits is ever increasing,” she said. “However, it’s important to recognize that data to support some of these associations are lacking, and oftentimes, a lot of the results are contradictory.”
As part of the International Study of Asthma and Allergies in Childhood, researchers evaluated the association between climate factors with the 12-month period prevalence rates of symptoms of atopic eczema in children. They found that patients who lived at higher latitudes and those who lived in areas where there were lower mean outdoor temperatures tended to have a higher prevalence of eczema symptoms. Worldwide, they found that symptoms of eczema were also prevalent in areas where there was lower indoor humidity.
“The authors concluded that they can’t really demonstrate a cause and effect, and that while latitude and temperature changes appear to affect the prevalence of eczema, they may do so indirectly, perhaps to changes in behavior and differences in sun exposure,” said Dr. Chiesa Fuxench, who was not involved with the study. “For example, we know that vitamin D is a protective risk factor for AD. Low vitamin D has been associated with more severe disease in some studies. We also know that UV exposure leads to the conversion of filaggrin degradation products such as trans-urocanic acid into cis-urocanic acid, which has been demonstrated to have immunosuppressive effects.”
A systematic review and meta-analysis of nine articles found small associations, which were significant, between being born in the winter (odds ratio, 1.15) and fall (OR, 1.16) and the risk of developing AD, compared with being born in the spring and summer. However, an analysis of satellite-derived data on air temperature across the United States from 1993 to 2011 found that as ambient air temperature increases, so did the risk for an ambulatory visit for AD to physicians from the National Ambulatory Medical Care Survey.
In all areas but the south, the largest number of AD visits occur in the spring. In the south, more AD visits occur in the summer. “This raises the point that we don’t really know everything when it comes to the influence of temperature and climate change on AD,” Dr. Chiesa Fuxench said.
Several maternal and neonatal risk factors for AD have been described in the literature, including the effect of prenatal exposure to antibiotics. In one large analysis, investigators assessed the association among 18-month-old children in the Danish National Birth Cohort, which included 62,560 mother-child pairs. They found that prenatal antibiotic use was associated with an increased odds of AD among children born to atopic mothers but only when used during all three trimesters (adjusted OR, 1.45). When they further stratified these analyses by type of birth (vaginal versus C-section), the association persisted in both groups, but was stronger among those delivered by C-section.
Probiotics
The role of probiotics to reduce the risk for AD has also been investigated. “We do know that probiotics could potentially be helpful, and it is often a readily available intervention,” Dr. Chiesa Fuxench said. “But the question still is how and when to supplement.”
In a systematic review and meta-analysis, researchers examined supplementation with probiotics given to breastfeeding mothers, pregnant mothers, or directly given to infants, and the risk of developing AD up to 18 months of age. They found that overall, probiotic exposure resulted in decreased risk of developing AD. In stratified analyses, the strongest association was observed for those who received probiotics during their pregnancy, during breastfeeding, and as an infant, which conferred about a 25% reduced risk.
Antibiotic exposure
What about early-life exposure to antibiotics on one’s risk for developing AD? A meta-analysis of 22 studies found that children who had been exposed to antibiotics during the first 2 years of life had an increased risk of eczema (OR, 1.26), compared with children who had not been exposed during the same period of time. “Interesting hypotheses can be generated from this study,” she said. “Perhaps future steps should focus on the impact of antibiotic exposure, the gut microbiome, and maternal risk factors for AD.”
In a separate study that supported these findings, researchers evaluated the association between the use of acid-suppressive medications and antibiotics during infancy and the development of allergic disease in early childhood. They found that exposure to either of these medications during the first six months of infancy resulted in a mild increased risk of developing AD, and concluded that they should be used during infancy only in situations of clear clinical benefit. “We should be good stewards of antibiotic use, in particular due to concern for antibiotic resistance in the population overall,” Dr. Chiesa Fuxench said.
Prevention strategies
Several AD prevention strategies have also been described in the medical literature, including the use of daily emollients during infancy. In a multicenter trial carried out in the United Kingdom, researchers tested whether daily use of emollient in the first year of life could prevent eczema in high-risk children, which was defined as having at least one first-degree relative with parent-reported eczema, allergic rhinitis, or asthma. The primary outcome was eczema at age 2 years. The researchers found no evidence to suggest that daily emollient use during the first year of life prevents eczema.
Another study, the PreventADALL trial of 2,397 infants, consisted of four treatment arms: a control group advised to follow national guidelines on infant nutrition; a skin intervention group that was asked to use skin emollients, a food intervention group with early introduction of peanut, cow’s milk, wheat, and egg, and a combined skin and food intervention. The investigators found no difference in the risk reduction of developing AD among patients who were treated with skin emollients or early complementary feeding, and concluded that these types of interventions should not be considered as interventions to prevent AD in this cohort of patients.
However, Dr. Chiesa Fuxench emphasized that emollients and moisturizers are an important part of the treatment regimen for AD patients. A Cochrane systematic review of nearly 80 randomized, controlled trials evaluating the use of emollients in eczema found that most moisturizers showed some beneficial effects in addition to active treatment, including prolonging the time to flare, reducing the number of flares, and reducing the amount of topical corticosteroids used.
For treatment, Dr. Chiesa Fuxench recommends a proactive approach focused on short-term induction therapy with intensive topical anti-inflammatories until the affected area is almost healed, followed by maintenance therapy that involves use of a long-term, low- to mid-potency steroid or a topical calcineurin inhibitor to previously affected areas. “These interventions have been shown to decrease the risk of recurrence and can shorten the treatment duration in the event of a flare,” she said.
She also favors a time-contingent approach to treating patients with AD. “As physicians, we tend to do our visits more as symptom contingent, which means when a patient is flaring. This reinforces the view that this is a difficult disease to treat, and that there is no hope,” she pointed out. But for chronic diseases, she added, “a time-contingent approach with appointments at set intervals leads to a different perception. It can result in better compliance, because skin care might be performed more regularly. It’s analogous to when you know you’re going to see the dentist so you floss more regularly the week before your appointment. There also seems to be less pressure on physicians and patients because you are seeing each other more frequently; you can talk more openly about what’s working and what’s not.”

AI detects ugly-duckling skin lesions for melanoma follow-up
.
The system could use photographs of large areas of patients’ bodies taken with ordinary cameras in primary care or by the patients themselves to screen for early-stage melanoma, said Luis R. Soenksen, PhD, a postdoctoral associate and venture builder at Massachusetts Institute of Technology in Cambridge, Mass.
“We believe we’re providing technology for that to happen at a massive scale, which is what is needed to reduce mortality rates,” he said in an interview.
He and his colleagues published their findings in Science Translational Medicine.
Diagnosing skin lesions has already proved one of the most promising medical applications of AI. In a 2017 paper, researchers reported that a deep neural network had classified skin lesions more accurately than did dermatologists. But so far, most such programs depend on experts to preselect the lesions worthy of analysis. And they use images from dermoscopy or single-lesion near-field photography.
Dr. Soenksen and colleagues wanted a system that could use a variety of cameras such as those in smartphones under a variety of conditions to assess lesions over wide areas of anatomy.
So they programmed their convolutional neural network to simultaneously use two approaches for screening lesions. Like the earlier systems, theirs looks for characteristics of individual lesions, such as asymmetry, border unevenness, color distribution, diameter, and evolution (ABCDE.) But it also looks for lesion saliency, a comparison of the lesions on the skin of one individual to identify the “ugly ducklings” that stand out from the rest.
They trained the system using 20,388 wide-field images from 133 patients at the Hospital Gregorio Marañón in Madrid, as well as publicly available images. The images were taken with a variety of consumer-grade cameras, about half of them nondermoscopy, and included backgrounds, skin edges, bare skin sections, nonsuspicious pigmented lesions, and suspicious pigmented lesions. The lesions in the images were visually classified by a consensus of three board-certified dermatologists.
Once they trained the system, the researchers tested it on another 6,796 images from the same patients, using the dermatologists’ classification as the gold standard. The system distinguished the suspicious lesions with 90.3% sensitivity (true positive), 89.9% specificity (true negative), and 86.56% accuracy.
Dr. Soenksen said he could envision photos acquired for screening in three scenarios. First, people could photograph themselves, or someone else at their homes could photograph them. These photos could even include whole nude bodies.
Second, clinicians could photograph patients’ body parts during medical visits for other purposes. “It makes sense to do these evaluations in the point of care where a referral can actually happen, like the primary care office,” said Dr. Soenksen.
Third, photos could be taken at places where people show up in bathing suits.
In each scenario, the system would then tell patients whether any lesions needed evaluation by a dermatologist.
To ensure privacy, Dr. Soenksen envisions using devices that do not transmit all the data to the cloud but instead do at least some of the calculations on their own. High-end smartphones have sufficient computing capacity for that, he said.
In their next phase of this work, the researchers would like to test the system on more skin of color cases and in more varied conditions, said Dr. Soenksen. And they would like to put it through randomized clinical trials, potentially using biopsies to validate the results.
That’s a key step, said Veronica Rotemberg, MD, PhD, director of the dermatology imaging informatics program at Memorial Sloan Kettering Cancer Center, New York.
“Usually when we think about melanoma, we think of histology as the gold standard, or specific subtypes of melanoma as a gold standard,” she said in an interview.
The technology also raises the question of excessive screening, she said. “Identifying the ugly duckling could be extremely important in finding more melanoma,” she said. “But in a patient who doesn’t have melanoma, it could lead to a lot of unnecessary biopsies.”
The sheer number of referrals generated by such a system could overwhelm the dermatologists assigned to follow up on them, she added.
Still, Dr. Rotemberg said, the study is “a good proof of concept.” Ugly duckling analysis is a very active area of AI research with thousands of teams of researchers worldwide working on systems similar to this one, she added. “I’m so excited for the authors.”
Neither Dr. Soenksen nor Dr. Rotemberg disclosed any relevant financial interests.

Methotrexate-associated hepatotoxicity risk differs between psoriasis, PsA, and RA patients
, in a large population-based study published in the Journal of the American Academy of Dermatology.
“These findings suggest that conservative liver monitoring is warranted in patients receiving methotrexate for psoriatic disease,” particularly psoriasis, the investigators concluded.
Joel M. Gelfand, MD, professor of dermatology at the University of Pennsylvania, Philadelphia, and colleagues performed a population-based cohort study of patients in Denmark in a hospital clinic with psoriasis, PsA, or RA who received methotrexate between 1997 and 2015; they compared rates of mild liver disease, moderate to severe liver disease, cirrhosis, and cirrhosis-related hospitalization between the groups.
In total, 5,687 patients with psoriasis, 6,520 patients with PsA, and 28,030 patients with RA met inclusion criteria: receiving one or more methotrexate prescriptions or having been dispensed methotrexate at the hospital clinic during the study period. Patients with RA tended to be older (mean, 59.7 years) and the group consisted of more women (71.6%) than the psoriasis patients (47.7 years; 45.3% women) or PsA patients (50.7 years; 57.3% women). In the groups, 17.9% to 23.5% had a history of smoking, and 2.8% to 7.4% had a history of alcohol abuse; the rates of diabetes were between 7.0% and 8.3%, and hyperlipidemia or statin use between 13.6% and 16.4%.
The average weekly methotrexate dose was similar in the three patient groups (a mean of 19.2-19.9 mg). However, the duration of methotrexate use among patients with RA was longer (a mean of 72.1 weeks) compared with the PsA (56.3 weeks) and psoriasis (43.0 weeks) groups. In addition, 50% of the patients in the RA group discontinued treatment after 80 months, 50% in the PsA group discontinued after 54 months, and 50% of patients with psoriasis discontinued after 26 months.
Patients with RA also had a higher cumulative methotrexate dose (a mean of 4.0 g) compared with PsA (3.0 g) and psoriasis (2.1) groups.
When the researchers looked at the incidence rate (IR) for the different categories of liver disease, they found the following differences:
- Mild liver disease: The IR per 1,000 person-years for patients with psoriasis was 4.22 per 1,000 person-years (95% confidence interval, 3.61-4.91), compared with 2.39 per 1,000 person-years (95% CI, 1.95-2.91) for patients with PsA, and 1.39 per 1,000 person-years (95% CI, 1.25-1.55) for patients with RA.
- Moderate to severe liver disease: The IR for patients with psoriasis was 0.98 per 1,000 person years (95% CI, 0.70-1.33), compared with 0.51 (95% CI, 0.32-0.77) for patients with PsA, and 0.46 (95% CI, 0.37-0.55) for patients with RA.
- Cirrhosis: The IR for patients with psoriasis was 1.89 per 1,000 person years (95% CI, 1.49-2.37), compared with 0.84 (95% CI, 0.59-1.16) for patients with PsA, and 0.42 (95% CI, 0.34-0.51) for patients with RA.
- Cirrhosis-related hospitalization: This was the least common outcome, with an IR per 1,000 person years of 0.73 (95% CI, 0.49-1.05) for patients with psoriasis, 0.32 (95% CI, 0.18-0.54) for patients with PsA, and 0.22 (95% CI, 0.17-0.29) for patients with RA.
When results were adjusted with Cox regression analyses, the psoriasis group had a significantly increased risk compared with the RA group with regard to mild liver disease (hazard ratio, 2.22; 95% CI, 1.81-2.72), moderate to-severe liver disease (HR, 1.56; 95% CI, 1.05-2.31), cirrhosis (HR, 3.38; 95% CI, 2.44-4.68), and cirrhosis-related hospitalization (HR, 2.25; 95% CI, 1.37-3.69). Compared with patients with RA, patients with PsA had a significantly increased risk of mild liver disease (HR, 1.27; 95% CI, 1.01-1.60) and cirrhosis (HR, 1.63; 95% CI, 1.10-2.42), but not moderate to severe liver disease or hospitalizations related to cirrhosis.
The researchers noted it is unclear why there was a difference in risk between the three groups of patients.
“While such differences in hepatotoxicity risk were previously attributed to differences in rates of alcoholism, obesity, diabetes, and other comorbidities between the disease populations, our study finds that the underlying disease influences liver disease risk independent of age, sex, smoking, alcohol use, diabetes, hyperlipidemia, overall comorbidity, and weekly methotrexate dose,” wrote Dr. Gelfand and colleagues.
As far as they know, their study “ is one of the first and largest population-based studies to directly compare” liver disease in these three groups of patients on methotrexate, they wrote, noting that earlier studies were smaller and frequently used indirect hepatic injury measures.
Limitations of the study included the inability to account for disease severity as well as the potential for disease misclassification, surveillance bias, and confounding by unmeasured variables such as body mass index. Further, the results do not show whether “liver disease is attributed to methotrexate use, the underlying disease, or a combination of both,” the researchers noted.

“These findings suggest that conservative liver monitoring is warranted in patients receiving methotrexate for psoriatic disease,” particularly psoriasis, the investigators concluded.
Joel M. Gelfand, MD, professor of dermatology at the University of Pennsylvania, Philadelphia, and colleagues performed a population-based cohort study of patients in Denmark in a hospital clinic with psoriasis, PsA, or RA who received methotrexate between 1997 and 2015; they compared rates of mild liver disease, moderate to severe liver disease, cirrhosis, and cirrhosis-related hospitalization between the groups.
In total, 5,687 patients with psoriasis, 6,520 patients with PsA, and 28,030 patients with RA met inclusion criteria: receiving one or more methotrexate prescriptions or having been dispensed methotrexate at the hospital clinic during the study period. Patients with RA tended to be older (mean, 59.7 years) and the group consisted of more women (71.6%) than the psoriasis patients (47.7 years; 45.3% women) or PsA patients (50.7 years; 57.3% women). In the groups, 17.9% to 23.5% had a history of smoking, and 2.8% to 7.4% had a history of alcohol abuse; the rates of diabetes were between 7.0% and 8.3%, and hyperlipidemia or statin use between 13.6% and 16.4%.
The average weekly methotrexate dose was similar in the three patient groups (a mean of 19.2-19.9 mg). However, the duration of methotrexate use among patients with RA was longer (a mean of 72.1 weeks) compared with the PsA (56.3 weeks) and psoriasis (43.0 weeks) groups. In addition, 50% of the patients in the RA group discontinued treatment after 80 months, 50% in the PsA group discontinued after 54 months, and 50% of patients with psoriasis discontinued after 26 months.
Patients with RA also had a higher cumulative methotrexate dose (a mean of 4.0 g) compared with PsA (3.0 g) and psoriasis (2.1) groups.
When the researchers looked at the incidence rate (IR) for the different categories of liver disease, they found the following differences:
- Mild liver disease: The IR per 1,000 person-years for patients with psoriasis was 4.22 per 1,000 person-years (95% confidence interval, 3.61-4.91), compared with 2.39 per 1,000 person-years (95% CI, 1.95-2.91) for patients with PsA, and 1.39 per 1,000 person-years (95% CI, 1.25-1.55) for patients with RA.
- Moderate to severe liver disease: The IR for patients with psoriasis was 0.98 per 1,000 person years (95% CI, 0.70-1.33), compared with 0.51 (95% CI, 0.32-0.77) for patients with PsA, and 0.46 (95% CI, 0.37-0.55) for patients with RA.
- Cirrhosis: The IR for patients with psoriasis was 1.89 per 1,000 person years (95% CI, 1.49-2.37), compared with 0.84 (95% CI, 0.59-1.16) for patients with PsA, and 0.42 (95% CI, 0.34-0.51) for patients with RA.
- Cirrhosis-related hospitalization: This was the least common outcome, with an IR per 1,000 person years of 0.73 (95% CI, 0.49-1.05) for patients with psoriasis, 0.32 (95% CI, 0.18-0.54) for patients with PsA, and 0.22 (95% CI, 0.17-0.29) for patients with RA.
When results were adjusted with Cox regression analyses, the psoriasis group had a significantly increased risk compared with the RA group with regard to mild liver disease (hazard ratio, 2.22; 95% CI, 1.81-2.72), moderate to-severe liver disease (HR, 1.56; 95% CI, 1.05-2.31), cirrhosis (HR, 3.38; 95% CI, 2.44-4.68), and cirrhosis-related hospitalization (HR, 2.25; 95% CI, 1.37-3.69). Compared with patients with RA, patients with PsA had a significantly increased risk of mild liver disease (HR, 1.27; 95% CI, 1.01-1.60) and cirrhosis (HR, 1.63; 95% CI, 1.10-2.42), but not moderate to severe liver disease or hospitalizations related to cirrhosis.
The researchers noted it is unclear why there was a difference in risk between the three groups of patients.
“While such differences in hepatotoxicity risk were previously attributed to differences in rates of alcoholism, obesity, diabetes, and other comorbidities between the disease populations, our study finds that the underlying disease influences liver disease risk independent of age, sex, smoking, alcohol use, diabetes, hyperlipidemia, overall comorbidity, and weekly methotrexate dose,” wrote Dr. Gelfand and colleagues.
As far as they know, their study “ is one of the first and largest population-based studies to directly compare” liver disease in these three groups of patients on methotrexate, they wrote, noting that earlier studies were smaller and frequently used indirect hepatic injury measures.
Limitations of the study included the inability to account for disease severity as well as the potential for disease misclassification, surveillance bias, and confounding by unmeasured variables such as body mass index. Further, the results do not show whether “liver disease is attributed to methotrexate use, the underlying disease, or a combination of both,” the researchers noted.

Painful hand and foot plaques
This patient had hand and foot psoriasis with the classic thick scale and erythema on his palms and soles. Additionally, in the area of the sole toward the heel, he had hyperpigmented macules called mahogany spots that are another hallmark of psoriasis. Pitting and distal onycholysis were also visible on his right ring finger.
This case illustrates how the painful plaques seen in hand and foot psoriasis—and other forms of psoriasis—can interfere with work and usual daily activities. UVA or narrowband UVB light therapy is a treatment option but requires 3 visits per week, which is not conducive to most people’s work schedules. Acitretin can be prescribed to decrease the abnormal proliferation of keratinocytes; however, adverse reactions can be expected, like this patient’s dry skin and itching. Furthermore, acitretin is a retinoid, like isotretinoin, which can cause severe birth defects, as well as hypertriglyceridemia and transaminitis. Pregnancy needs to be avoided for 3 years due to the teratogenicity and long washout period, so it should not be used in women with reproductive potential.1
This patient was initially treated with topical calcipotriene (a vitamin D derivative) and clobetasol (high-potency topical steroid) bid but did not have adequate improvement. Screening lab tests showed elevated liver enzymes, precluding treatment with methotrexate (and acitretin, which he’d received previously). He was started on apremilast, an oral phosphodiesterase inhibitor, because his insurance denied adalimumab. Apremilast can cause diarrhea, depression, nausea, and headache. Other than some loose stools, the patient tolerated apremilast well and showed significant improvement in his psoriasis at his 3-month follow-up visit.

Emerging treatments for molluscum contagiosum and acne show promise
, but that could soon change, according to Leon H. Kircik, MD.
“The treatment of molluscum is still an unmet need,” Dr. Kircik, clinical professor of dermatology at the Icahn School of Medicine at Mount Sinai, New York, said at the Orlando Dermatology Aesthetic and Clinical Conference. However, a proprietary drug-device combination of cantharidin 0.7% administered through a single-use precision applicator, which has been tested in phase 3 studies, is currently under FDA review. The manufacturer, Verrica Pharmaceuticals resubmitted a new drug application for the product, VP-102, in December 2020.
“VP-102 features a visualization agent so the injector can see which lesions have been treated, as well as a bittering agent to mitigate oral ingestion by children. Complete clearance at 12 weeks ranged from 46% to 54% of patients, while lesion count reduction compared with baseline ranged from 69% to 82%.”
Acne
In August, 2020, clascoterone 1% cream was approved for the treatment of acne in patients 12 years and older, a development that Dr. Kircik said “can be a game changer in acne treatment.” Clascoterone cream 1% exhibits strong, selective anti-androgen activity by targeting androgen receptors in the skin, not systemically. “It limits or blocks transcription of androgen responsive genes, but it also has an anti-inflammatory effect and an anti-sebum effect,” he explained.
According to results from two phase 3 trials of the product, a response of clear or almost clear on the IGA scale at week 12 was achieved in 18.4% of those on treatment vs. 9% of those on vehicle in one study (P less than .001) and 20.3% vs. 6.5%, respectively, in the second study (P less than .001). Clascoterone is also being evaluated for treating androgenetic alopecia.
In Dr. Kircik’s clinical experience, retinoids can be helpful for patients with moderate to severe acne. “We always use them for anticomedogenic effects, but we also know that they have anti-inflammatory effects,” he said. “They actually inhibit toll-like receptor activity. They also inhibit the AP-1 pathway by causing a reduction in inflammatory signaling associated with collagen degradation and scarring.”
The most recent retinoid to be approved for the topical treatment of acne was 0.005% trifarotene cream, in 2019, for patients aged 9 years and older. “But when we got the results, it was not that exciting,” a difference of about 3.6 (mean) inflammatory lesion reduction between the active and the vehicle arm, said Dr. Kircik, medical director of Physicians Skin Care in Louisville, Ky. “According to the package insert, treatment side effects included mild to moderate erythema in 59% of patients, scaling in 65%, dryness in 69%, and stinging/burning in 56%, which makes it difficult to use in our clinical practice.”
The drug was also tested for treating truncal acne. However, one comparative study showed that tazarotene 0.045% lotion spread an average of 36.7 square centimeters farther than the trifarotene cream, which makes the tazarotene lotion easier to use on the chest and back, he said.
Dr. Kircik also discussed 4% minocycline, a hydrophobic, topical foam formulation of minocycline that was approved by the FDA in 2019 for the treatment of moderate to severe acne, for patients aged 9 and older. In a 12-week study that involved 1,488 patients (mean age was about 20 years), investigators observed a 56% reduction in inflammatory lesion count among those treated with minocycline 4%, compared with 43% in the vehicle group.
Dr. Kircik, one of the authors of the study, noted that the hydrophobic composition of minocycline 4% allows for stable and efficient delivery of an inherently unstable active pharmaceutical ingredient such as minocycline. “It’s free of primary irritants such as surfactants and short chain alcohols, which makes it much more tolerable,” he said. “The unique physical foam characteristics facilitate ease of application and absorption at target sites.”
Dr. Kircik reported that he serves as a consultant and/or adviser to numerous pharmaceutical companies, including Galderma, the manufacturer of trifarotene cream.

Cellulitis treatment recommendations
He noticed discomfort today and saw that his left lower leg had redness and was warm. He does not recall scratches or injury to his leg. He has not had fever or chills. He has no other symptoms. His diabetes has been well controlled with diet and metformin.
On exam, his blood pressure is 120/70, pulse is 80, temperature is 37 degrees Celsius.
In the left lower extremity, the patient had 1+ edema at the ankle, with a 14-cm x 20-cm warm, erythematous area just above the ankle and extending proximally.
His labs found an HCT of 44 and a WBC of 12,000. What do you recommend?
A) Vascular duplex exam
B) 1st generation cephalosporin
C) 1st generation cephalosporin + TMP/Sulfa
D) Oral clindamycin
E) IV vancomycin
This patient has cellulitis and should receive a beta lactam antibiotic, which will have the best coverage and lowest minimal inhibitory concentration for the likely organism, beta hemolytic streptococci. Clindamycin would likely work, but it has greater side effects. This patient does not need coverage for methicillin-resistant staphylococcus aureus (MRSA). I know many of you, if not most, know this, but I want to go through relevant data and formal recommendations, because of a recent call I received from a patient.
My patient had a full body rash after receiving cephalexin + TMP/sulfa [trimethoprim-sulfamethoxazole] treatment for cellulitis. In recent years the addition of TMP/sulfa to strep treatment to also cover MRSA has become popular, especially in emergency department and urgent care settings.
Moran and colleagues studied cephalexin + TMP/sulfa vs. cephalexin and placebo in patients with uncomplicated cellulitis.1 The outcome measured was clinical cure, and there was no difference between groups; clinical cure occurred in 182 (83.5%) of 218 participants in the cephalexin plus TMP/sulfa group vs. 165 (85.5%) of 193 in the cephalexin group (difference, −2.0%; 95% confidence interval, −9.7% to 5.7%; P = .50).
Jeng and colleagues studied patients admitted for a cellulitis, and evaluated the patients’ response to beta-lactam antibiotics.2 Patients had acute and convalescent serologies for beta hemolytic strep. Almost all evaluable patients with positive strep studies (97%) responded to beta-lactams, and 21 of 23 (91%) with negative studies responded to beta-lactams (overall response rate 95%). This study was done during a time of high MRSA prevalence.
The most recent Infectious Diseases Society of America guidelines for skin and soft tissue infections, recommend oral penicillin, cephalexin, dicloxacillin, or clindamycin for mild cellulitis, and IV equivalent if patients have moderate cellulitis.3 If abscesses are present, then drainage is recommended and MRSA coverage. Kamath and colleagues reported on how closely guidelines for skin and soft tissue infections were followed.4 In patients with mild cellulitis, only 36% received guideline-suggested antibiotics. The most common antibiotic prescribed that was outside the guidelines was trimethoprim-sulfamethoxazole.
Myth: Cellulitis treatment should include MRSA coverage.
My advice: Stick with beta-lactam antibiotics, unless an abscess is present. There is no need to add MRSA coverage for initial treatment of mild to moderate cellulitis.

My advice: Stick with beta-lactam antibiotics, unless an abscess is present. There is no need to add MRSA coverage for initial treatment of mild to moderate cellulitis.

He noticed discomfort today and saw that his left lower leg had redness and was warm. He does not recall scratches or injury to his leg. He has not had fever or chills. He has no other symptoms. His diabetes has been well controlled with diet and metformin.
On exam, his blood pressure is 120/70, pulse is 80, temperature is 37 degrees Celsius.
In the left lower extremity, the patient had 1+ edema at the ankle, with a 14-cm x 20-cm warm, erythematous area just above the ankle and extending proximally.
His labs found an HCT of 44 and a WBC of 12,000. What do you recommend?
A) Vascular duplex exam
B) 1st generation cephalosporin
C) 1st generation cephalosporin + TMP/Sulfa
D) Oral clindamycin
E) IV vancomycin
This patient has cellulitis and should receive a beta lactam antibiotic, which will have the best coverage and lowest minimal inhibitory concentration for the likely organism, beta hemolytic streptococci. Clindamycin would likely work, but it has greater side effects. This patient does not need coverage for methicillin-resistant staphylococcus aureus (MRSA). I know many of you, if not most, know this, but I want to go through relevant data and formal recommendations, because of a recent call I received from a patient.
My patient had a full body rash after receiving cephalexin + TMP/sulfa [trimethoprim-sulfamethoxazole] treatment for cellulitis. In recent years the addition of TMP/sulfa to strep treatment to also cover MRSA has become popular, especially in emergency department and urgent care settings.
Moran and colleagues studied cephalexin + TMP/sulfa vs. cephalexin and placebo in patients with uncomplicated cellulitis.1 The outcome measured was clinical cure, and there was no difference between groups; clinical cure occurred in 182 (83.5%) of 218 participants in the cephalexin plus TMP/sulfa group vs. 165 (85.5%) of 193 in the cephalexin group (difference, −2.0%; 95% confidence interval, −9.7% to 5.7%; P = .50).
Jeng and colleagues studied patients admitted for a cellulitis, and evaluated the patients’ response to beta-lactam antibiotics.2 Patients had acute and convalescent serologies for beta hemolytic strep. Almost all evaluable patients with positive strep studies (97%) responded to beta-lactams, and 21 of 23 (91%) with negative studies responded to beta-lactams (overall response rate 95%). This study was done during a time of high MRSA prevalence.
The most recent Infectious Diseases Society of America guidelines for skin and soft tissue infections, recommend oral penicillin, cephalexin, dicloxacillin, or clindamycin for mild cellulitis, and IV equivalent if patients have moderate cellulitis.3 If abscesses are present, then drainage is recommended and MRSA coverage. Kamath and colleagues reported on how closely guidelines for skin and soft tissue infections were followed.4 In patients with mild cellulitis, only 36% received guideline-suggested antibiotics. The most common antibiotic prescribed that was outside the guidelines was trimethoprim-sulfamethoxazole.

Pandemic puts patients with psoriatic disease off seeking medical help
More than half of respondents to a recent survey looking at how the COVID-19 pandemic has affected people with psoriasis or psoriatic arthritis (PsA) said that they had avoided seeking medical care in person with a doctor or at a hospital.
Moreover, around a quarter had their appointment with a rheumatologist canceled, rescheduled, or conducted virtually. Another 1 in 10 had their treatment plan disrupted, and 6% had to change or stop treatment entirely.
The mental health impact of living with these conditions during the pandemic was also notable, said Rachael Manion, the executive director of the Canadian Association of Psoriasis Patients (CAPP), which conducted the survey in collaboration with the Canadian Psoriasis Network (CPN) and Unmasking Psoriasis.
“It’s important to know that there have been a lot of different impacts of the pandemic on people living with psoriatic arthritis and psoriasis. Mental health in particular has had a really big hit as a result,” she said at the Canadian Arthritis Research Conference: Research with Impact.
“About half of the people who responded to our survey noted that their mental health was ‘worse’ or ‘much worse’ during the pandemic,” she said at the meeting, which was sponsored by the Arthritis Society, the Canadian Rheumatology Association, and Canada’s Institute of Musculoskeletal Health and Arthritis. Anxiety and feelings of isolation were reported by a respective 57% and 58% of respondents, and 40% reported depression.
“We can compare that to our earlier information around depression,” Ms. Manion said, which showed that, prior to the pandemic, 24% of people with psoriasis and 23% of those with PsA had said they experienced depression.
“What I found alarming looking at these results was that about a third of people were experiencing despair. Now that’s a really big, scary, overwhelming emotion that has a lot of burden on your mental health,” Ms. Manion said.
Despite the substantial effects on mental health, only 29% of respondents said they had been able to access mental health services during the pandemic.
To look at the impact of the COVID-19 pandemic on the psoriasis and PsA community in Canada, three patient advocacy groups – CAPP, CPN, and Unmasking Psoriasis – codeveloped a survey to look at the disease experience before and after the start of the COVID-19 pandemic. The survey was performed once, with 830 respondents providing information on their lives with psoriasis or PsA in the months before the start of the pandemic and at the time they were surveyed in September and October 2020.
Most of the survey respondents lived in Ontario, Quebec, British Columbia, or Alberta, although other provinces or territories were represented. Almost all respondents (96%) had psoriasis, and 60% also had PsA.
Pre-COVID, nearly half (49%) of patients said that they had not been seen by a rheumatologist, and 39% had not seen a dermatologist for treatment. Asked why, 56% and 27%, respectively, had not been referred, 9% and 15% said they had no specialist located nearby, and 7% and 10% stated that the wait list was too long.
“This tells us that there’s a lot more work that can be done and a lot more education of general practitioners and family medicine professionals about the benefits and the value of specialized care for psoriatic arthritis,” Ms. Manion suggested.
Before the pandemic, joint pain was occurring in 88% of patients, stiffness in 71%, and joint swelling in 67%. Disease flares or sudden periods of worsening occurred on a daily basis for 17%, and around one in five (21%) experienced multiple flares every month.
Prepandemic data also highlighted the negative impact that living with psoriasis or PsA has on people’s ability to sleep, interactions and intimacy with others, and on their school or work lives.
During the pandemic, around a quarter (26%) of respondents said they had worse or much worse access to employment, as well as its benefits such as a stable income (24%). A minority of respondent also described worse access to prescription medication (15%) and over-the-counter medication (13%).
“There are all kinds of things going on for patients in our community: changes to their work, changes to their drug coverage, their ability to sleep and sleep well, their mental health, and their ability to access care and treatments as part of their disease management,” Ms. Manion said.
Her final message to health care professionals was: “I just want to encourage you to continue to check in with your patients about what their experiences have been during the pandemic, and to really consider those impacts as you’re working with them to manage their disease.”
The survey received funding support from AbbVie, Bausch Health, Boehringer Ingelheim, Janssen, LEO Pharma, and Novartis.
