Atopic Dermatitis

Patients with moderate to severe atopic dermatitis (AD) affecting between 10% and 50% of their body surface area (BSA) account for the majority of responders to baricitinib 2 mg, results from an analysis of phase 3 data showed.

“This proposed clinical tailoring approach for baricitinib 2 mg allows for treatment of patients who are more likely to respond to therapy and rapid decision on discontinuation of treatment for those who are not likely to benefit from baricitinib 2 mg,” Eric L. Simpson, MD, said during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis virtual symposium.

Baricitinib is an oral, reversible and selective Janus kinase 1/JAK2 inhibitor that is approved in Europe for the treatment of moderate to severe AD in adults who are candidates for systemic therapy. In the United States, it is approved for treating rheumatoid arthritis, and is currently under Food and Drug Administration review in the United States for AD.

For the current analysis, Dr. Simpson, professor of dermatology at Oregon Health & Science University, Portland, and colleagues set out to identify responders to baricitinib 2 mg using a tailored approach based on baseline BSA affected and early clinical improvement in the phase 3 monotherapy trial BREEZE-AD5. The trial enrolled 440 patients: 147 to placebo, 147 to baricitinib 1 mg once daily, and 146 to baricitinib 2 mg once daily. The primary endpoint was Eczema Area and Severity Index (EASI)–75 at week 16.

“Understanding which patients can benefit most from this treatment was our goal,” Dr. Simpson said. “By tailoring your therapy, you can significantly improve the patient experience, increase the cost-effectiveness of a therapy, and you can ensure that only patients who are likely to benefit are exposed to a drug.”

The researchers used a classification and regression tree algorithm that identified baseline BSA as the strongest predictor of EASI-75 response at week 16. A BSA cutoff of 50% was established as the optimal cutoff for sensitivity and negative predictive value. Results for EASI-75 and Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD) scores of 0 or 1 were confirmed using a BSA of 10%-50% at baseline to predict response, compared with a BSA or greater than 50% at baseline.

Sensitivity analyses revealed that about 90% of patients with an EASI-75 response were in the BSA 10%-50% group. Conversely, among patients with a BSA greater than 50%, the negative predictive value was greater than 90%, “so there’s a 90% chance you’re not going to hit that EASI-75 at week 16 if your BSA is greater than 50%,” Dr. Simpson explained. “The same holds true for vIGA-AD, so that 50% cutoff is important for understanding whether someone is going to respond or not.”

On the EASI-75, 38% of patients in the BSA 10%-50% group responded to baricitinib at week 16, compared with 10% in the BSA greater than 50% group. A similar association was observed on the vIGA-AD, where 32% of patients in the BSA 10%-50% group responded to baricitinib at week 16, compared with 5% in the BSA greater than 50% group.

When stratified by early response assessed at week 4, based on a 4-point improvement or greater on the Itch Numeric Rating Scale, 55% of those patients became EASI-75 responders, compared with 17% who were not. A similar association was observed by early response assessed at week 8.

“Due to the rapid onset of response, clinical assessment of patients after 4-8 weeks of initiation of baricitinib 2 mg treatment provided a positive feedback to patients who are likely to benefit from long-term therapy,” Dr. Simpson said. “This analysis may allow for a precision-medicine approach to therapy in moderate to severe AD.”

The study was supported by Eli Lilly, and was under license from Incyte. Dr. Simpson reported serving as an investigator for and consultant to numerous pharmaceutical companies.

Trigger avoidance is a common cornerstone of management for all patients with atopic dermatitis (AD), but implementing the strategy is easier said than done.

“Guidelines on trigger avoidance are written as if it’s easy to do,” Jonathan I. Silverberg, MD, PhD, MPH, said during the Revolutionizing Atopic Dermatitis virtual symposium. “It turns out that trigger avoidance is really complicated.”

He and his colleagues conducted a study of most common triggers for itch based on a prospective dermatology practice–based study of 587 adults with AD . About two-thirds (65%) reported one or more itch trigger in the past week and 36% had three or more itch triggers in the past week. The two most common triggers were stress (35%) and sweat (31%).

“To me, this is provocative, because this is not how I was trained in residency,” said Dr. Silverberg, director of clinical research in the division of dermatology at George Washington University, Washington. “I was trained that it’s all about excess showering, dry air, or cold temperature. Those are important, but the most common triggers are stress and sweat.”

AD triggers are also commonly linked to seasonality. “If you ask patients when their AD is worse, sometimes it’s winter,” he said. “Sometimes it’s spring. Sometimes it’s summer. It turns out that there is a distinct set of triggers that are associated with AD seasonality.” Wintertime worsening of disease is associated with cold temperature and weather change, he continued, while springtime worsening of disease is often linked to weather change and dry air. Common summertime triggers for flares include hot temperature, heat, sweat, weather change, sunlight, humid air, and dry air. “In the fall, the weather change again comes up as a trigger. Humid air does as well.”

In their prospective study, Dr. Silverberg and colleagues found that 90% of those who had at least three itch triggers reported 3 months or less of AD remission in the past year, “meaning that 90% are reporting persistent disease when they have multiple itch triggers,” he said. In addition, 78% reported two or more flares per year and 61% reported that AD is worse during certain seasons.

Potential mitigation strategies for stress include stress management, biofeedback, meditation, relaxation training, and mindfulness. “These don’t necessarily require expensive psychotherapy,” he said. Freely available iPhone apps can be incorporated into daily practice, such as Calm, Relax with Andrew Johnson, Nature Sounds Relax and Sleep, Breathe2Relax, and Headspace.

Many AD patients are sedentary and avoid vigorous physical activity owing to heat and sweat as triggers. Simple solutions include exercising in a cooler temperature environment, “not just using fans,” he said. “Take a quick shower right after working out and consider pre- and/or post treatment with topical medication.”

High temperature and sweating can be problematic at bedtime, he continued. Even if the indoor temperature is 70° F, that might jump to 85° F or 90° F under a thick blanket. “That heat can trigger itch and may cause sweating, which can trigger itch,” said Dr. Silverberg, who has AD and is director of patch testing at George Washington University. Potential solutions include using a lighter blanket, lowering the indoor temperature, and wearing breathable pajamas.

Dryness, another common AD trigger, can be secondary to a combination of low outdoor and/or indoor humidity. “Lower outdoor humidity is a particular problem in the wintertime, because cold air doesn’t hold moisture as well,” he said. “That’s why the air feels much dryer in the wintertime. There’s also a problem of indoor heating and cooling. Sometimes central air systems can lower humidity to the point where it’s bone dry.”

In an effort to determine the impact of specific climatic factors on the U.S. prevalence of AD, Dr. Silverberg and colleagues conducted a study using a merged analysis of the 2007 National Survey of Children’s Health from a representative sample of 91,642 children aged 0-17 years and 2006-2007 measurements from the National Climate Data Center and Weather Service. They found that childhood AD prevalence was increased in geographical areas that use more indoor heat and cooling and had lower outdoor humidity. “So, we see that there’s a direct correlate of this dryness issue that is leading to more AD throughout the U.S.,” he said.

Practical solutions to mitigate the effect of dry air on AD include opening windows to allow entry of moist air, “which can be particularly helpful in residences that are overheated,” he said. “I deal with this a lot in patients who live in dormitories. Use humidifiers to add moisture back into the air. Aim for 40%-50% indoor humidity to avoid mold and dust mites. It’s better to use demineralized water to reduce bacterial growth. This can be helpful for aeroallergies. Of note, there are really no well-done studies that have examined the efficacy of humidifiers in AD, but based on our anecdotal experience, this is a good way to go.”

Cold temperatures and trigger intense itch, even in the setting of high humidity. “For me personally, this is one of my most brutal triggers,” Dr. Silverberg said. “When I’m in a place with extremes of cold, I get a rapid onset of itch, a mix of itch and pain, particularly on the dorsal hands. For solutions, you can encourage patients to avoid extremely low temperatures, to bundle up, and to potentially use hand warmers or other heating devices.”

Clothing can be a trigger as well, especially tight-fitting clothes, hot and nonbreathable clothes, and large-diameter wool, which has been shown to induce itching and irritation. Mitigation strategies include wearing loose-fitting, lightweight, nonirritating fabric. “Traditional cotton and silk fabrics have mixed evidence in improving AD but are generally safe,” he said. “Ultra- or superfine merino wool has been shown to be nonpruritic. There is sparse evidence to support chemically treated/coated clothing for AD, but this may be an emerging area.”

Dr. Silverberg pointed out variability of cultural perspectives and preferences for bathing practices, including temperature, duration, frequency, optimal bathing products, and the use of loofahs and other scrubbing products. “This stems from different perceptions of what it means to be clean, and how dry our skin should feel after a shower,” he said. “Many clinicians and patients were taught that regular bathing is harmful in AD. It turns out that’s not true.”

In a recently published systematic review and meta-analysis of 13 studies, he and his colleagues examined efficacy outcomes of different bathing/showering regimens in AD. All 13 studies showed numerically reduced AD severity with any bathing regimen in at least one time point. Numerical decreases over time were observed for body surface area (BSA), Eczema Area and Severity Index (EASI), and/or SCORAD measures for daily and less than daily bathing, with or without application of emollients or topical corticosteroids. In random effects regression models, taking baths more than or less than seven times per week were not associated with significant differences of Cohen’s D scores for EASI, SCORAD, or BSA. “The take-home message here is, let your AD patients bathe,” Dr. Silverberg said. “Bathing is good. It can be channeled to help the eczema, but it has to be done the right way.”

Patients should be counseled to use nonirritating cleansers and shampoos, avoid excessively long baths/showers, avoid excessively hot baths/showers, avoid excessive rubbing or scrubbing of skin, and to apply emollients and/or topical corticosteroids immediately after the bath/shower.

PROMIS Itch-Triggers is a simple and feasible checklist to screen for the most common itch triggers in AD in clinical practice (patients are asked to check off which of the following have caused their itch in the previous 7 days: cold temperature, hot temperature, heat, sweat, tight clothing, fragrances, boredom, talking about itch, stress, weather change, sunlight, humid air, dry air). “It takes less than 1 minute to complete,” he said. “Additional testing with skin patch and/or prick testing may be warranted to identify allergenic triggers.”

Dr. Silverberg reported that he is a consultant to and/or an advisory board member for several pharmaceutical companies. He is also a speaker for Regeneron and Sanofi and has received a grant from Galderma.

Numerical decreases over time were observed for body surface area (BSA), Eczema Area and Severity Index (EASI), and/or SCORAD measures for daily and less than daily bathing, with or without application of emollients or topical corticosteroids. In random effects regression models, taking baths more than or less than seven times per week were not associated with significant differences of Cohen’s D scores for EASI, SCORAD, or BSA. “The take-home message here is, let your AD patients bathe,” Dr. Silverberg said. “Bathing is good. It can be channeled to help the eczema, but it has to be done the right way.”

Patients should be counseled to use nonirritating cleansers and shampoos, avoid excessively long baths/showers, avoid excessively hot baths/showers, avoid excessive rubbing or scrubbing of skin, and to apply emollients and/or topical corticosteroids immediately after the bath/shower.

PROMIS Itch-Triggers is a simple and feasible checklist to screen for the most common itch triggers in AD in clinical practice (patients are asked to check off which of the following have caused their itch in the previous 7 days: cold temperature, hot temperature, heat, sweat, tight clothing, fragrances, boredom, talking about itch, stress, weather change, sunlight, humid air, dry air). “It takes less than 1 minute to complete,” he said. “Additional testing with skin patch and/or prick testing may be warranted to identify allergenic triggers.”

Dr. Silverberg reported that he is a consultant to and/or an advisory board member for several pharmaceutical companies. He is also a speaker for Regeneron and Sanofi and has received a grant from Galderma.

Dupilumab treatment with concomitant topical corticosteroids provided rapid and sustained improvement in itch intensity and frequency in children aged 6-11 years with severe atopic dermatitis.

The findings come from a post hoc analysis of a phase 3 trial known as LIBERTY AD PEDS (NCT03345914) that Gil Yosipovitch, MD, presented during a late-breaking research session at the Revolutionizing Atopic Dermatitis virtual symposium.

By week 16, a higher weekly proportion of dupilumab-treated patients achieved a 2-point or more improvement in worst itch score, compared with placebo (72% in the 300-mg q4w group vs. 74% in the 200-mg q2w group; P less than or equal to .001). The same association held true for the daily proportion of dupilumab-treated patients who achieved a 4-point or more improvement in worst itch score, compared with placebo (54% vs. 61%; P less than or equal to .001).

Next, the researchers evaluated the proportion of patients reporting the number of days with itchy skin over the previous 7 days as assessed from the Patient-Oriented Eczema Measure (POEM) itch item question: “Over the last week, on how many days has your child’s skin been itchy because of their eczema?” By week 16, the majority of children treated with dupilumab achieved a reduction of days experiencing itch from every day at baseline to at most 2 days, with some improvement to zero days per week.

“Overall, in the LIBERTY AD PEDS trial, dupilumab was well tolerated and data were consistent with the known dupilumab safety profile observed in adults and adolescents,” Dr. Yosipovitch said. “Injection site reactions and conjunctivitis were more common with dupilumab. Infections and AD exacerbations were more common with placebo.”

The study was sponsored by Sanofi and Regeneron Pharmaceuticals. Dr. Yosipovitch and coauthors reporting having received financial grants and research grants from numerous pharmaceutical companies.

A diagnosis of atopic dermatitis in individuals ages 15 years or older, compared with controls without atopic dermatitis, was nearly twice as likely to be associated with autoimmune disease, in a case control study derived from Swedish national health care registry data.

Atopic dermatitis (AD) is known to be associated with other atopic conditions, and there is increasing evidence it is associated with some nonatopic conditions, including some cancers, cardiovascular disease, and neuropsychiatric disorders, according to Lina U. Ivert, MD, of the dermatology and venereology unit at the Karolinska Institutet, Stockholm, and coauthors. There are also some data indicating that autoimmune diseases, particularly those involving the skin and gastrointestinal tract, are more common in people with AD.

The aim of their study, published in the British Journal of Dermatology, was to investigate a wide spectrum of autoimmune diseases for associations with AD in a large-scale, population-based study using Swedish registers. Findings could lead to better monitoring of comorbidities and deeper understanding of disease burden and AD pathophysiology, they noted.
 

Large-scale study

With data from the Swedish Board of Health and Welfare’s National Patient Register on inpatient diagnoses since 1964 and specialist outpatient visits since 2001, the investigators included all patients aged 15 years and older with AD diagnoses (104,832) and matched them with controls from the general population (1,022,435). The authors noted that the large number of people included in the analysis allowed for robust estimates, and underscored that 80% of the AD patients included had received their diagnosis in a dermatology department, which reduces the risk of misclassification.

Association with autoimmune disease

The investigators found an association between AD and autoimmune disease, with an adjusted odds ratio) of 1.97 (95% confidence interval, 1.93-2.01). The association was present with several organ systems, particularly the skin and gastrointestinal tract, and with connective tissue diseases. The strongest associations with autoimmune skin diseases were found for dermatitis herpetiformis (aOR, 9.76; 95% CI, 8.10-11.8), alopecia areata (aOR, 5.11; 95% CI, 4.75-5.49), and chronic urticaria (aOR, 4.82; 95% CI, 4.48-5.19).

AD was associated with gastrointestinal diseases, including celiac disease (aOR, 1.96; 95% CI, 1.84-2.09), Crohn disease (aOR 1.83; CI, 1.71-1.96), and ulcerative colitis (aOR 1.58; 95% CI, 1.49-1.68).

Connective tissue diseases significantly associated with AD included systemic lupus erythematosus (aOR, 1.65; 95% CI, 1.42-1.90), ankylosing spondylitis (aOR, 1.46; 95% CI, 1.29-1.66), and RA (aOR, 1.44; 95% CI,1.34-1.54]). Hematologic or hepatic autoimmune disease associations with AD were not observed.
 

Stronger association with multiple diseases

The association between AD and two or more autoimmune diseases was significantly stronger than the association between AD and having one autoimmune disease. For example, the OR for AD among people with three to five autoimmune diseases was 3.33 (95% CI, 2.86-3.87), and was stronger in men (OR, 3.96; 95% CI, 2.92-5.37) than in women (OR, 3.14; 95% CI, 2.63-3.74).
 

Sex differences

In the study overall, the association with AD and autoimmune diseases was stronger in men (aOR, 2.18; 95% CI, 2.10-2.25), compared with women (aOR, 1.89; 95% CI, 1.85-1.93), but this “sex difference was only statistically significant between AD and RA and between AD and Celiac disease,” they noted.

Associations between AD and dermatomyositis, systemic scleroderma, systemic lupus erythematosus, Hashimoto’s disease, Graves disease, multiple sclerosis, and polymyalgia rheumatica were found only in women. Dr. Ivert and coauthors observed that “women are in general more likely to develop autoimmune diseases, and 80% of patients with autoimmune diseases are women.”
 

Provocative questions

Commenting on the findings, Jonathan Silverberg, MD, PhD, MPH, associate professor of dermatology, George Washington University, Washington, said, “At a high level, it is important for clinicians to recognize that atopic dermatitis is a systemic immune-mediated disease. AD is associated with higher rates of comorbid autoimmune disease, similar to psoriasis and other chronic inflammatory skin diseases.”

“At this point, there is nothing immediately actionable about these results,” noted Dr. Silverberg, who was not an author of this study. “That said, in my mind, they raise some provocative questions: What is the difference between AD in adults who do versus those who do not get comorbid autoimmune disease? Does AD then present differently? Does it respond to the same therapies? These will have to be the subject of future research.”

The study was funded by the Swedish Asthma and Allergy Association Research Foundation, Hudfonden (the Welander-Finsen Foundation), and the Swedish Society for Dermatology and Venereology. The authors disclosed no conflicts of interest.

Poor sleep health and attention regulation problems are common in young children with atopic dermatitis (AD), and the burden intensifies with worse severity, results from a national survey demonstrated.

“We think it’s important for dermatologists and pediatricians to be monitoring children with AD for sleep and attention dysregulation,” Nina Y. Zhou said during a late-breaking research session at the Revolutionizing Atopic Dermatitis virtual symposium. “It’s also important to highlight sleep hygiene habits to improve sleep health overall.”

In an effort to determine the impact of AD severity on these symptoms in young children with AD and characterize sleep health and attention regulation behaviors, Ms. Zhou, a medical student at Northwestern University, Chicago, and colleagues drew from a national survey distributed via panel company OP4G and the National Eczema Association that was conducted with parents of 60 children with AD aged 1-5 years. Questionnaires included the Patient Reported Outcomes Measurement Information System (PROMIS) Early Childhood Sleep Health Measures to assess sleep health, the Peak Pruritus NRS to measure itch severity, and the Multidimensional Assessment Profile of Attention Regulation (MAPS-AR) to measure attention dysregulation related to inattention and hyperactivity. The researchers performed linear regression to determine the predictors of sleep health and attention dysregulation.

The mean age of 60 children was 3 years, 55% were male, 32% were black, 42% had severe disease, 42% had moderate disease, and 16% had mild disease. Children with more extensive AD were significantly more likely to report worse sleep disturbance. The proportion of children who reported sleep disturbance on at least 5 nights per week was 67% among those with severe AD, 24% among those with moderate AD, and 0% among those with mild AD.

In addition, 72% of parents of children with severe AD reported trouble paying attention at least 3 times per week “no matter what was going on,” compared with 24% of those with moderate AD and none of those with mild AD.

Parents of children with more severe AD reported more itch-related burden and significantly decreased quality of life for their children. For example, 76% of parents with children who had severe AD reported “because of itch, their child was frustrated,” compared to 44% of those with moderate AD and 10% with mild AD.

In fully adjusted linear regression analysis, the strongest predictors of sleep disturbance were AD severity (unstandardized beta value = 0.79, P less than .01) and being Black (unstandardized beta value = 3.89, P = .03). AD severity (unstandardized beta value = 1.22, P less than .01) and being Black (unstandardized beta value = 7.79, P less than .01) also predicted more attention dysregulation.

Household income appeared to differ significantly based on AD severity groups. “If you have mild AD, you are more likely to come from a higher income household,” Ms. Zhou said.

She concluded her presentation by calling for future studies with larger samples sizes to establish causality and directional effects between AD severity, itch, sleep, race, and attention.

The study was funded by the Agency for Healthcare Research and Quality. Ms. Zhou reported having no financial disclosures.

A child with eczema is more likely to be given food allergy tests if seen by an allergist or a pediatrician and less likely to be given these tests if seen by a general practitioner or dermatologist.

“In our survey, we found evidence of variation in practice and a spectrum of opinion on what to do to treat eczema in children,” Matthew Ridd, MD, University of Bristol (England) said in an interview.

His clinician survey was sent to 155 health care providers. Findings were presented at the Food Allergy and Anaphylaxis Meeting–European Consortium on Application of Flow Cytometry in Allergy Congress, held virtually. They revealed big differences in the way physicians follow up on eczema. For a child with eczema with reported reactions to food, 20 of 22 (91%) allergists and 22 of 30 (73%) pediatricians always order food allergy tests.

But only 16 of 65 (25%) general practitioners and 3 of 12 (25%) dermatologists always order tests in the same situation.

A total of 155 health care practitioners responded to the survey, sent by a U.K. research team. Of those, 26 were unable to order allergy tests. Of the remaining 129, 65 (50%) specialized in general practice, 30 (23%) in pediatrics, 22 (17%) in the treatment of allergies, and 12 (9%) in dermatology.

Their opinions varied on when to order food allergy tests. For children with severe eczema who had no prior reaction to food, 8 of 22 (36%) practitioners specializing in allergy said they would order food allergy tests, as did 9 of 30 (30%) in pediatrics.

Of those surveyed, only 6 of 65 in general practice (9%) said they would request an allergy test for severe eczema for a patient with no allergy history, and no dermatologists (0%) would order the tests.

Only if a parent specifically requested a food allergy test would practitioners respond in a similar way. About two-thirds of all respondents said they would sometimes order the test if a parent asked (general practice, 75%; pediatrics, 63%; allergy, 68%; dermatology, 75%).

Dr. Ridd said in an interview that it’s not surprising there’s a wide variation in practice, inasmuch as the guidelines are quite convoluted and complex. “Eczema is a common problem, but we don’t have any good evidence to guide clinicians on when to consider food allergy as a possible cause.”

Current guidelines advise calling for allergy tests only when eczema is difficult to treat. “But this is a complex decision. We know that a third of children with eczema are at higher risk for food allergy,” Dr. Ridd said. A 2014 study published in Clinical and Experimental Allergy showed that infants with eczema are six times more likely to have egg allergy and 11 times more likely to have peanut allergy by 12 months than infants without eczema (Clin Exp Allergy. 2014;45:255-64).

Food allergy is a sticky subject, he said. “So we have to wonder, are general practitioners frightened to raise the question?

“We definitely see uncertainty around it.”

He suspects that parents may also be hesitant to bring it up. “They are likely thinking about it even if they don’t ask,” Dr. Ridd said. “I think it’s important to test for food allergy, to provide reassurance. Once we show it’s not an allergy, we can focus on topical treatment.”
 

Treating eczema with emollients may increase likelihood of food allergy

In a separate presentation at the FAAM-EUROBAT congress, Maeve Kelleher, MD, Imperial College London, said that, rather than help reduce eczema, emollients in infants probably cause an increase in the risk for skin infection and food allergy. Her research team performed a systematic review of 25,827 participants in randomized controlled trials of the use of skin care interventions in term infants for primary prevention of eczema and food allergy. The study focused especially on topical creams.

Dr. Kelleher reported that skin care interventions “probably don’t prevent eczema. They probably increase local skin infections and may increase food allergy.”

Other interventions need to be explored, she said. “Maybe prevention should be along the line of looking at the microbiome, or exposures on the skin when you’re younger.”

Dr. Ridd and Dr. Kelleher have disclosed no relevant financial relationships.

Eczema herpeticum and staphylococcal scalded skin syndrome can be emergencies in children and require immediate care, warned dermatologist George Hightower, MD, PhD, in a presentation at MedscapeLive’s virtual Women’s & Pediatric Dermatology Seminar.

Eczema herpeticum is a condition in which a herpes simplex virus (HSV-1 or HSV-2) is superimposed over preexisting eczema. “The infection may be primary and sustained from a close contact or result in some of our older patients from reactivation and spread through autoinoculation,” said Dr. Hightower, of Rady Children’s Hospital and the University of California, both in San Diego.

Signs, he said, include acute worsening of atopic dermatitis with new-onset vesicles, pustules, and “punched-out” hemorrhagic crusted erosions. “Presentation ranges from mild to transient to life threatening.”

Potential complications include meningitis, encephalitis, hepatitis, and chronic conjunctivitis. “That’s why immediate ophthalmological evaluation is needed when there’s involvement on the face near the eye,” he said.

As for management and care, “where I have concern for HSV patients, I get HSV [polymerase chain reaction] as well as a bacterial culture,” he said. But even before the results are available, empiric treatment with acyclovir can be appropriate. “It’s got to be systemic for these kids with severe involvement,” he said, and they should also be started on medication for staphylococci and streptococci.

During his presentation, Dr. Hightower also highlighted staphylococcal scalded skin syndrome. Patients with the disease commonly have concurrent skin pain (which can appear to be fussiness), fever, irritability, malaise, and poor feeding. Examination may reveal widespread erythema with accentuation at folds/peeling at hands and large sheets of superficial peeling scale with diffuse erythema.

Widespread skin involvement “results not from the presence of staph throughout the skin, but the exotoxin that it produces that becomes systemic,” he said. “Clinical diagnosis is supported by presence of S. aureus on bacterial culture, but the presence of staph is not necessary to make the diagnosis. When in doubt, histopathology is helpful. But again, it’s not necessary to make the diagnosis.”

Cases can be managed with a first- or second-generation cephalosporin, he said. Alternative therapies include antistaphylococcus penicillinase-resistant penicillins (oxacillin or nafcillin) or vancomycin.

While Dr. Hightower doesn’t use clindamycin in these patients, he said it’s an option that some dermatologists consider because of its antistaphylococcus activity. “Historically, people thought it may decrease exotoxin production. The big concern if you are going to use clindamycin is that there are high rates of community resistance,” he said. “So you want to be careful that you know your resistance patterns wherever you are. Follow up on culture to make sure that you have adequate coverage for the bug that the kiddo in front of you has.”

Dermatologists frequently learn about skin conditions that are directly linked to diet. For example, we know that nutritional deficiencies can impact the hair, skin, and nails, and that celiac disease manifests with dermatitis herpetiformis of the skin. Patients commonly ask their dermatologists about the impact of diet on their skin. There are many outdated myths, but research on the subject is increasingly demonstrating important associations. Dermatologists must become familiar with the data on this topic so that we can provide informed counseling for our patients. This article reviews the current literature on associations between diet and 3 common cutaneous conditions—acne, psoriasis, and atopic dermatitis [AD]—and provides tips on how to best address our patients’ questions on this topic.

Acne

Studies increasingly support an association between a high glycemic diet (foods that lead to a spike in serum glucose) and acne; Bowe et al1 provided an excellent summary of the topic in 2010. This year, a large prospective cohort study of more than 24,000 participants demonstrated an association between adult acne and a diet high in milk, sugary beverages and foods, and fatty foods.2 In prospective cohort studies of more than 6000 adolescent girls and 4000 adolescent boys, Adebamowo et al3^,4 demonstrated a correlation between skim milk consumption and acne. Whey protein supplementation also has been implicated in acne flares.^5,6 The biological mechanism of the impact of high glycemic index foods and acne is believed to be mainly via activation of the insulinlike growth factor 1 (IGF-1) pathway, which promotes androgen synthesis and increases androgen bioavailability via decreased synthesis of sex hormone binding globulin.^1,2 Insulinlike growth factor 1 also stimulates its downstream target, mammalian target of rapamycin (mTOR), leading to activation of antiapoptotic and proliferation signaling, ultimately resulting in oxidative stress and inflammation causing acne.² Penso et al² noted that patients with IGF-1 deficiency (Laron syndrome) never develop acne unless treated with exogenous IGF-1, further supporting its role in acne formation.⁷ There currently is a paucity of randomized controlled trials assessing the impact of diet on acne.

Psoriasis 

The literature consistently shows that obesity is a predisposing factor for psoriasis. Additionally, weight gain may cause flares of existing psoriasis.⁸ Promotion of a healthy diet is an important factor in the management of obesity, alongside physical activity and, in some cases, medication and bariatric surgery.⁹ Patients with psoriasis who are overweight have been shown to experience improvement in their psoriasis after weight loss secondary to diet and exercise.^8,10 The joint American Academy of Dermatology and National Psoriasis Foundation guidelines recommend that dermatologists advise patients to practice a healthy lifestyle including a healthy diet and communicate with a patient’s primary care provider so they can be appropriately evaluated and treated for comorbidities including metabolic syndrome, diabetes, and hyperlipidemia.¹¹ In the NutriNet-Santé cohort study, investigators found an inverse correlation between psoriasis severity and adherence to a Mediterranean diet, which the authors conclude supports the hypothesis that this may slow the progression of psoriasis.¹² In a single meta-analysis, it was reported that patients with psoriasis have a 3-fold increased risk for celiac disease compared to the general population.1³ It remains unknown if these data are generalizable to the US population. Dermatologists should consider screening patients with psoriasis for celiac disease based on reported symptoms. When suspected, it is necessary to order appropriate serologies and consider referral to gastroenterology prior to recommending a gluten-free diet, as elimination of gluten prior to testing may lead to false-negative results.

Atopic Dermatitis

Patients and parents/guardians of children with AD often ask about the impact of diet on the condition. A small minority of patients may experience flares of AD due to ongoing, non–IgE-mediated allergen exposure.¹⁴ Diet as a trigger for flares should be suspected in children with persistent, moderate to severe AD. In these patients, allergen avoidance may lead to improvement but not resolution of AD. Allergens ordered from most common to least common are the following: eggs, milk, peanuts/tree nuts, shellfish, soy, and wheat.¹⁵ Additionally, it is important to note that children with AD are at higher risk for developing life-threatening, IgE-mediated food allergies compared to the general population (37% vs 6.8%).^16,17 The LEAP (Learning Early about Peanut Allergy) study led to a paradigm shift in prevention of peanut allergies in high-risk children (ie, those with severe AD and/or egg allergy), providing data to support the idea that early introduction of allergenic foods such as peanuts may prevent severe allergies.¹⁸ Further studies are necessary to clarify the population in which allergen testing and recommendations on food avoidance are warranted vs early introduction.¹⁹

Conclusion

Early data support the relationship between diet and many common dermatologic conditions, including acne, psoriasis, and AD. Dermatologists should be familiar with the evidence supporting the relationship between diet and various skin conditions to best answer patients’ questions and counsel as appropriate. It is important for dermatologists to continue to stay up-to-date on the literature on this subject as new data emerge. Knowledge about the relationship between diet and skin allows dermatologists to not only support our patients’ skin health but their overall health as well.

Additionally, weight gain may cause flares of existing psoriasis.⁸ Promotion of a healthy diet is an important factor in the management of obesity, alongside physical activity and, in some cases, medication and bariatric surgery.⁹ Patients with psoriasis who are overweight have been shown to experience improvement in their psoriasis after weight loss secondary to diet and exercise.^8,10 The joint American Academy of Dermatology and National Psoriasis Foundation guidelines recommend that dermatologists advise patients to practice a healthy lifestyle including a healthy diet and communicate with a patient’s primary care provider so they can be appropriately evaluated and treated for comorbidities including metabolic syndrome, diabetes, and hyperlipidemia.¹¹ In the NutriNet-Santé cohort study, investigators found an inverse correlation between psoriasis severity and adherence to a Mediterranean diet, which the authors conclude supports the hypothesis that this may slow the progression of psoriasis.¹² In a single meta-analysis, it was reported that patients with psoriasis have a 3-fold increased risk for celiac disease compared to the general population.1³ It remains unknown if these data are generalizable to the US population. Dermatologists should consider screening patients with psoriasis for celiac disease based on reported symptoms. When suspected, it is necessary to order appropriate serologies and consider referral to gastroenterology prior to recommending a gluten-free diet, as elimination of gluten prior to testing may lead to false-negative results.

Atopic Dermatitis

Patients and parents/guardians of children with AD often ask about the impact of diet on the condition. A small minority of patients may experience flares of AD due to ongoing, non–IgE-mediated allergen exposure.¹⁴ Diet as a trigger for flares should be suspected in children with persistent, moderate to severe AD. In these patients, allergen avoidance may lead to improvement but not resolution of AD. Allergens ordered from most common to least common are the following: eggs, milk, peanuts/tree nuts, shellfish, soy, and wheat.¹⁵ Additionally, it is important to note that children with AD are at higher risk for developing life-threatening, IgE-mediated food allergies compared to the general population (37% vs 6.8%).^16,17 The LEAP (Learning Early about Peanut Allergy) study led to a paradigm shift in prevention of peanut allergies in high-risk children (ie, those with severe AD and/or egg allergy), providing data to support the idea that early introduction of allergenic foods such as peanuts may prevent severe allergies.¹⁸ Further studies are necessary to clarify the population in which allergen testing and recommendations on food avoidance are warranted vs early introduction.¹⁹

Conclusion

Early data support the relationship between diet and many common dermatologic conditions, including acne, psoriasis, and AD. Dermatologists should be familiar with the evidence supporting the relationship between diet and various skin conditions to best answer patients’ questions and counsel as appropriate. It is important for dermatologists to continue to stay up-to-date on the literature on this subject as new data emerge. Knowledge about the relationship between diet and skin allows dermatologists to not only support our patients’ skin health but their overall health as well.

Dermatologists are more likely than are nondermatologists to follow practice guidelines when prescribing antihistamines to treat pruritus associated with atopic dermatitis (AD), according to an analysis of a national database.

Although physicians commit themselves to providing equitable treatment to all patients, significant disparities remain in the dermatologic care of Black patients, who constitute 13% of the US population, which continues to grow increasingly diverse.¹ Despite these changes in the population, the literature demonstrates that dermatologic training does not adequately focus on unique presentations of cutaneous pathology in the Black population.^2,3 Accordingly, medical students lack proper training in how skin disorders manifest in people of color. Compounding the problem, only 3% of dermatologists are Black, creating a cultural barrier that can compromise care for Black patients.^2,4 Racial disparities in dermatology training can compromise treatment, patient satisfaction, and outcomes.³

Issues in Medical Education Training and Resources

Lack of diversity in the resources used for dermatology training in medical schools affects diagnosis and treatment, as skin manifestations such as hypersensitivity reactions, rashes, and cancer can appear differently on different skin tones.⁵ A study of medical students’ ability to diagnose common dermatologic pathologies found that when trainees were presented with photographs of dark skin, their accuracy in identifying urticaria, squamous cell carcinoma, and even atopic dermatitis was reduced, despite these diseases being more prevalent in children of African American ancestry.^4,6

Dermatologic diseases also can have different distributions in different races; for example, on non–sun-exposed sites, squamous cell carcinoma in Black patients occurs at 8.5 times the frequency of White patients.⁷ Failure to identify diseases accurately due to insufficient training can have grave consequences for patients. Although skin cancer is less common in individuals with skin of color, it is associated with greater morbidity and mortality, in part due to delayed diagnosis.⁷

Inadequate research, reporting, and instruction on dermatologic findings in patients with darker complexions further compound racial disparities in dermatology. A 2006 study of the representation of darker skin in major dermatology educational resources found that only 2% of teaching events at American Academy of Dermatology annual meetings focused on skin of color. Furthermore, the study determined that many common diseases in patients with dark skin, such as acne vulgaris and pityriasis rosea, were completely absent or limited in dermatology textbooks.⁸

Impact on the Black Patient Experience

Patients’ therapeutic relationship with their physician also is damaged by limitations in training in diverse skin color. A study that assessed Black patients seen in a skin of color clinic (SOCC) compared to Black patients seen in a non-SOCC found that non-SOCC patients reported a lower degree of respect, dignity, understanding, and trust compared to the patients seen in a SOCC. Black patients expressed specific concerns about non-SOCC dermatologists’ knowledge of abnormalities that present in darker skin and Black hair.³ These findings are compounded by reports suggesting that, independent of care, structural racism contributes to dermatologic disease severity by influencing patient education level, household income, and degree of exposure to harmful environmental irritants.⁶

Racial disparities continue to be seen in the makeup of the universe of dermatologists and skin researchers. As of 2016, only 3% of dermatologists were Black, making dermatology one of the least diverse medical specialties.² Increasing the diversity of the dermatology workforce is important to improve patient satisfaction and treatment, both for minority and nonminority patients. Compared to race-discordant medical visits, race-concordant visits were shown to have a higher rate of satisfaction and better shared decision-making.⁹ Also, minority physicians are more likely to practice health care in areas that are traditionally underserved and to care for patients who do not have health insurance, making their participation essential in addressing some of the baseline disparities Black patients face in securing quality dermatologic care.¹

Structural Racism in Medicine

Changing dermatology training to ensure improved treatment of Black patients requires not only increased attention to differences in disease presentation but also heightened awareness of underlying genetic, environmental, and structural factors that contribute to the disease course.⁶ For example, there is evidence suggesting that structural racism in the form of residential segregation, lower socioeconomic status, and lower educational attainment contribute to disease severity in conditions such as atopic dermatitis. There is additional evidence suggesting that White patients are more readily offered therapeutic options than Black patients. A study of racial disparities in psoriasis treatment found that Black patients with moderate to severe psoriasis were 70% less likely to receive treatment with a biologic than White patients, independent of socioeconomic factors, comorbidities, and insurance plans.¹⁰

Moving Forward

Although research continues to underscore racial disparities in dermatology, some leaders in the field are actively combating these problems. A recent study that looked at representations of dark skin images in medical educational resources found far greater representation of dark pigmented skin in web-based resources than in traditional printed texts. Specifically, the online resource VisualDx (https://www.visualdx.com/) features 28.5% dark skin images compared to 10.3% (on average) in printed dermatology books.¹¹ There also is increasing public awareness of these issues, with organizations such as the Skin of Color Society (http://skinofcolorsociety.org/) helping to promote interest in racial disparities in dermatology. Physicians also have created textbooks and social media accounts focused on dermatologic manifestations in skin of color.¹² The Instagram account Brown Skin Matters (@brownskinmatters) has created a publicly accessible online resource where physicians and patients can see and post dermatologic diseases in skin of color.⁵

Final Thoughts

It is critical that physicians be trained to identify skin and hair manifestations of disease and disorders in Black patients. Training can be improved by including more images of skin manifestations in dark skin, both in medical school curricula and in new editions of dermatology textbooks. Training also must teach students about hair in Black individuals and how to properly treat it as well as related conditions of the hair and scalp.¹³ More research also is needed to better understand how dermatologists can improve the patient experience for Black patients. Residency programs must work to increase diversity among dermatology trainees.

Lastly, dermatology education should increasingly be supplemented with newer, web-based resources that show dermatologic manifestations across the spectrum of skin tones. Dermatology training must be adapted to better account for diverse patient populations and increase its focus on the systems that produce baseline disparities in disease morbidity and mortality.
