Practical pearls guide treatment of psoriasis in tricky areas
LAS VEGAS – With the right regimen, a majority of patients with psoriasis can achieve at least a Psoriasis Area and Severity Index (PASI) 75 score, Jennifer Soung, MD, said in a presentation at MedscapeLive’s annual Las Vegas Dermatology Seminar.
The array of treatment options includes mainstay topicals, new nonsteroidals, traditional oral systemics, new oral systemics, biologics, and light therapy, said Dr. Soung, director of clinical research at Harbor-UCLA Medical Center, Santa Ana, Calif. However, she said.
For these areas, make sure the diagnosis of psoriasis is correct, to avoid wasting time on the wrong course of treatment, Dr. Soung emphasized.
Scalp strategies
The scalp is often the first area of the body affected by psoriasis, and patients with severe scalp psoriasis may have minimal plaques on the body, Dr. Soung said. However, a differential diagnosis should include seborrheic dermatitis, she noted.
For most cases of scalp psoriasis, “start with localized topical treatment,” such as vitamin D and corticosteroid combination therapy, or excimer laser, Dr. Soung advised.
Systemic treatments with demonstrated effectiveness on scalp psoriasis in post hoc analyses of patients with moderate to severe plaque psoriasis include adalimumab, etanercept, ixekizumab, and secukinumab. Studies specifically focused on treatment of scalp psoriasis have shown success with secukinumab and apremilast, she noted.
Roflumilast foam, 0.3%, is in development and is an emerging option for scalp psoriasis. (A cream formulation of roflumilast, a topical phosphodiesterase 4 inhibitor, was approved for treatment of plaque psoriasis in July 2022.) A phase 2b study of roflumilast foam showed that approximately one-third of patients with scalp psoriasis achieved a status of clear based on scalp-investigator global assessment, compared with approximately 3% of those on vehicle, and similar results were seen in a recently completed phase 3 trial for scalp and body psoriasis, she added.
Facial psoriasis
Patients with facial psoriasis tend to be younger, and they may have more severe disease overall, Dr. Soung said. Given the sensitivity of facial skin, “it is nice to have a nonsteroidal option,” she noted. Current novel nonsteroidal therapies include a cream formulation of tapinarof, an aryl hydrocarbon receptor agonist, which was approved earlier this year for plaque psoriasis in adults, and roflumilast cream. Vitamin D and topical calcineurin inhibitors are options as well, she said.
Intertriginous tricks
Intertriginous (inverse) psoriasis is distinct from other areas in that the plaques are usually smooth and well-demarcated, with little or no scaling, Dr. Soung said. Erosions or signs of maceration may be present. The prevalence of inverse psoriasis is approximately 30%, but the prevalence on external genitalia is 80%, she noted. For inverse psoriasis, topical corticosteroids can result in adverse events such as poor wound healing and skin fragility, and some patients resist the idea of a steroid and don’t adhere to the medication, she added. Dr. Soung recommended topical corticosteroids for the short term, and topical calcineurin inhibitors or calcipotriol for the long term.
New topical options for inverse psoriasis include tapinarof and roflumilast, Dr. Soung said. For tapinarof, the phase 3 PSOARING program included assessment of tolerability in sensitive skin areas and found little to no irritation. Similarly, treatment with roflumilast cream was effective and well tolerated by patients with intertriginous plaque psoriasis in the DERMIS-1 and DERMIS-2 studies, she said.
Genital psoriasis
Ask patients with psoriasis about genital psoriasis, because they often are too embarrassed to provide that information on their own, said Dr. Soung. In fact, 63% of patients with psoriasis report ever experiencing genital psoriasis, but it often goes undiagnosed and undertreated, which has a significant impact on patient quality of life and sexual health.
A differential diagnosis of genital psoriasis should include dermatitis, tinea or candidiasis, and even squamous cell carcinoma, she noted. Other considerations include fixed drug eruption, lichen nitidus, lichen sclerosus, and scabies.
Dr. Soung’s first line of treatment for genital psoriasis is low-potency topical corticosteroids for 2-4 weeks. If long-term topical therapy is needed, alternatives include calcineurin inhibitors and vitamin D analogs, she said. The new topicals roflumilast and tapinarof are options as well, she said.
For those patients with severe and extensive genital psoriasis, consider systemic therapy, possibly with ixekizumab or secukinumab, she added. Patients with moderate to severe genital psoriasis treated with apremilast have shown improvement at week 16, in an ongoing clinical trial, she noted.
Palmoplantar involvement
For patients with palmar plantar psoriasis, “don’t underestimate the impact on quality of life,” said Dr. Soung. Approximately 12%-16% of patients with psoriasis report palmoplantar involvement, she noted.
Palmoplantar psoriasis can be stubborn, and many patients will need combination therapy with topicals and systemics, she said. “I am very curious about how well our new topical nonsteroidals will work in these areas,” she added.
Dr. Soung starts patients with palmoplantar psoriasis with a “potent to super-potent” twice daily topical corticosteroid, with or without occlusion. Her first-line systemic therapy is acitretin, 10-50 mg daily. However, keep in mind that acitretin is contraindicated in pregnancy, and also may cause side effects including cheilitis, alopecia, and peeling skin, she cautioned.
During the question and answer session, Dr. Soung was asked whether she routinely biopsies patients with palmoplantar psoriasis. “Not always,” was her answer. Instead, she looks for clues elsewhere on the body to confirm the diagnosis.
Nail know-how
Approximately 23%-27% of patients with psoriasis experience nail involvement, said Dr. Soung. Nail psoriasis can appear on the nail plate as pitting, onycholysis, or subungual hyperkeratosis, or in the nail bed as splinter hemorrhages or oil spots, she said.
For patients with psoriasis of the nails only, Dr. Soung described the use of high-potency topical corticosteroids, with or without calcipotriol. In her experience, she said that intralesional steroids for nail psoriasis are torturous to patients. For patients who have failed topical therapy or have psoriasis in other areas, with or without psoriatic arthritis, she advised the use of either IL-17 antagonists (secukinumab, ixekizumab, brodalumab) or IL-23 antagonists (risankizumab, guselkumab).
Dr. Soung disclosed serving as a consultant or advisor for Arcutis, Bristol Myers Squibb Company, Dermavant, and Novartis. She also disclosed serving as a speaker or member of the speakers’ bureau for AbbVie, Amgen, Arcutis, Bristol Myers Squibb Company, Celgene, Leo Pharma, Eli Lilly, Novartis, Ortho Dermatologics, Pfizer, Regeneron, and Sanofi, as well as research funding from AbbVie, Amgen, Arcutis, Castle Biosciences, Dermavant, KoBio, Kyowa Kirin, Leo Pharma, Eli Lilly, Novartis, Pfizer, and UCB.

AT INNOVATIONS IN DERMATOLOGY
A cost-effective de-escalation strategy in advanced melanoma
Response-adapted , an economic analysis found.
“The rising costs of cancer therapies are becoming untenable for both patients and payers, and there is both clinical and economic benefit to finding less expensive treatment alternatives,” Wolfgang Kunz, MD, University Hospital, Ludwig Maximilian University of Munich, told this news organization.
This economic analysis “highlights that leveraging modern diagnostic capabilities can do just that: Pairing drug regimens with CT-image analysis to optimize dosages can reduce health care costs and improve clinical outcomes,” Dr. Kunz said.
The study was published online in JAMA Dermatology.
While the use of immunotherapies over the past decade has improved the prognosis for patients with advanced melanoma, these drugs come with a hefty price tag.
One potential way to help reduce costs: de-escalate therapy. The ADAPT-IT trial demonstrated similar progression-free and overall survival among patients who received response-adapted ipilimumab discontinuation and those who received standard of care.
In the current analysis, Dr. Kunz and colleagues wanted to understand whether this response-adapted approach was also cost effective.
The team applied economic modeling to data from the ADAPT-IT trial as well as CheckMate 067, in which patients received standard of care four doses of combination ipilimumab-nivolumab followed by nivolumab monotherapy. In the ADAPT-IT trial, patients also initially received the immunotherapy combination but had CT scans to determine their response after two doses; if they responded, patients discontinued ipilimumab and continued with nivolumab monotherapy.
Overall, ADAPT-IT showed that responders could forgo the additional two doses of ipilimumab plus nivolumab while maintaining similar progression-free survival and overall survival seen at 18 months in the CheckMate 067 trial.
The current economic analysis, based on 41 patients from ADAPT-IT and 314 from CheckMate 067, showed a potential reduction in health care costs of $19,891 per patient with the response-adapted approach.
Response-adapted treatment was the cost-effective option in 94% of simulated scenarios.
When extrapolated to 2019 incidence rates of distant melanoma cases, yearly national savings could reach about $58 million.
“In the relatively small space of immunotherapies in advanced melanoma, we hope this analysis motivates clinicians to consider response-adapted treatment,” Dr. Kunz told this news organization.
“On the larger scale, this analysis serves as a stepping stone to more response-guided treatment protocols,” Dr. Kunz added. “With drug costs rising and imaging capabilities growing, more frequent image-guided adjustments are a perfect fit into the personalized care model.”
When applying the cost savings noted in this analysis across all treated patients, “the economic impact may be profound,” said Joseph Skitzki, MD, surgical oncologist, Roswell Park Comprehensive Cancer Center, Buffalo, N.Y., who wasn’t involved in the study. The “financial toxicity of cancer care is increasingly recognized as a potential barrier to optimal outcomes and any measures to mitigate cost may be impactful.”
However, Dr. Skitzki said several caveats need to be considered.
One is that the data included from ADAPT-IT only included 41 patients, compared with 314 patients from CheckMate 067.
“It is possible that a larger real-world study utilizing the ADAPT-IT protocol may not be as favorable in terms of outcomes and could lessen the economic impact of de-escalation, although any form of de-escalation is likely to have a cost benefit,” Dr. Skitzki said in an interview.
A real-world response–adapted de-escalation clinical trial, with an emphasis on costs and a benchmark of similar progression-free and overall survival, should be conducted before the de-escalated option becomes “practice changing,” Dr. Skitzki said.
Jeffrey Weber, MD, PhD, deputy director, Perlmutter Cancer Center, NYU Langone Health, New York, also urged caution in interpreting the results.
“I would not base treatment decisions on a small sampling of 41 patients in the absence of a randomized comparison,” Dr. Weber told this news organization. “Without a proper comparison, I would not advocate using only two doses of ipilimumab-nivolumab to make decisions on treatment.”
Dr. Skitzki added that, while “studies like this one are desperately needed to lessen the economic impact of new and emerging combination immunotherapies,” there is likely also a “disincentive for pharmaceutical companies to conduct this type of research.”
This research had no specific funding. Dr. Kunz and Dr. Skitzki reported no relevant conflicts of interest. Dr. Weber disclosed relationships with Merck, Genentech, AstraZeneca, Pfizer, Regeneron, and GSK, among others, and holds equity in Cytomx, Biond, NexImmune, and Immunomax.

This research had no specific funding. Dr. Kunz and Dr. Skitzki reported no relevant conflicts of interest. Dr. Weber disclosed relationships with Merck, Genentech, AstraZeneca, Pfizer, Regeneron, and GSK, among others, and holds equity in Cytomx, Biond, NexImmune, and Immunomax.

Education about OTC tools key for patients with acne and rosacea
LAS VEGAS – , Hilary E. Baldwin, MD, of Rutgers Robert Wood Johnson Medical Center, New Brunswick, N.J., said in a presentation at Medscape Live’s annual Las Vegas Dermatology Seminar.
In some cases, the use of good-quality over-the -counter skin care products can improve acne without prescription treatment, said Dr. Baldwin, who is medical director of the Acne Treatment and Research Center, New York. Good skin care can enhance the effects of prescription medication by decreasing side effects such as inflammation, pain, and erythema, and improving compliance; and use of OTC products has not been shown to interfere with the efficacy of prescription products, she noted.
However, patient education about OTC products is key, she said. In particular, “cleansers are a double-edged sword,” Dr. Baldwin emphasized.
Cleansing is important to preserve barrier function, but “there is a risk of skin damage” if cleansers are too harsh, she said. The goal is to remove dirt, oils, and bacteria without disrupting the lipids, proteins, and normal flora that keep skin healthy, and to avoid altering pH, she added.
Key considerations for OTC cleansers include surfactants, pH, and patient preferences, Dr. Baldwin said.
Surfactants, the main components of OTC cleansers, can do more harm than good in some cases. Surfactants break down impurities on the skin surface, but not all are created equal, and some may cause skin irritation, she explained.
Surfactants fall into four categories: nonionic (no charge), anionic (negative charge), cationic (positive charge), and amphoteric (dual charge). Of these, cationic surfactants have the highest level of antimicrobial activity.
Many patients with acne seek out antibacterial cleansers, but many of these products have a high pH, which can inhibit healthy skin function and promote inflammation, Dr. Baldwin noted.
The right OTC skin care products can normalize pH, which promotes repair of the skin barrier and reduces inflammation, she said. While some products are labeled as “gentle,” they may have a high pH, and many products don’t list a pH, Dr. Baldwin pointed out. Many antibacterial products have pH levels in the 10-12 range, while true soaps fall in the 9-10 range, and hydrating liquid cleansers often land in the 5-7 range, she said.
“Most of our patients don’t know what ingredients to look for” in a cleanser, she noted. However, data show that a majority of patients prefer a foaming cleanser, enjoy the face-washing experience – and wash their faces at least twice a day, with a range of products including bath soap, said Dr. Baldwin. Consequently, “educate your patient about moisturizing,” she advised.
For patients with greasy or oily skin, Dr. Baldwin recommends lipid-free foaming cleansers, such as those with ceramides or glycerin. For patients with dry, irritated acne, she advises once-daily washing only, without cleansing devices, which includes washcloths, she said. Look for hydrating cleansers that are nonfoaming or slightly foaming for these patients, she added.
Another tip for patients is to remind them that “sebum is not a moisturizer,” said Dr. Baldwin. Acne patients may still need moisturizers, especially if they experience dry skin as a side effect of their acne medication, but finding the right fit can be a challenge requiring some trial and error, she noted.
OTC products for rosacea
Dr. Baldwin also addressed the use of OTC products for patients with rosacea. For cleansers, she recommends the same hydrating, nonfoaming categories as for her acne patients, with a once-daily, no-device regimen. She advises rosacea patients to avoid pure humectants for moisturizing and noted that silicone-based products are often the least irritating.
Seek moisturizers with ceramides, hyaluronic acid, glycerin, or niacinamide, she said. Data have shown that effective moisturization improves the ability of patients with rosacea to use and adhere to their prescription medications, Dr. Baldwin emphasized. Moisturizers also can make the medication more effective by enhancing the penetration of products such as azelaic acid, she added.
No acne or rosacea visit is complete until overall skin care has been discussed, Dr. Baldwin said.
Dr. Baldwin disclosed serving as a consultant or adviser for Almirall, EPI Health, Galderma, La Roche Posay, Ortho Dermatologics, Sun, and Vyne; and serving as a speaker or member of the speakers’ bureau for Almirall, Galderma, La Roche Posay, Ortho Dermatologics, and Sun.

AT INNOVATIONS IN DERMATOLOGY
Hairdressers have ‘excess risk’ of contact allergies
.
“Research has shown that up to 70% of hairdressers suffer from work-related skin damage, mostly hand dermatitis, at some point during their career,” write Wolfgang Uter of Friedrich-Alexander University Erlangen-Nürnberg and coauthors. In general, they write, occupational skin diseases such as hand dermatitis represent up to 35% of reported occupational diseases. The study was published online in Contact Dermatitis.
Wet work and skin contact with detergents and hairdressing chemicals are top risk factors for developing occupational skin disease in this population, according to the researchers.
To further understand the burden of occupational contact allergy in hairdressers, the investigators gathered evidence published since 2000 on contact allergies to hair cosmetic chemicals. They searched the literature for nine substances selected beforehand by experts and stakeholders. The researchers also examined the prevalence of sensitization between hairdressers and other individuals given skin patch tests.
Substance by substance
Common potentially sensitizing cosmetic ingredients reported across studies included p-phenylenediamine (PPD), persulfates (mostly ammonium persulfate [APS]), glyceryl thioglycolate (GMTG), and ammonium thioglycolate (ATG).
In a pooled analysis, the overall prevalence of contact allergy to PPD was 4.3% in consecutively patch-tested patients, but in hairdressers specifically, the overall prevalence of contact allergy to this ingredient was 28.6%, reviewers reported.
The pooled prevalence of contact allergy to APS was 5.5% in consumers and 17.2% in hairdressers. In other review studies, contact allergy risks to APS, GMTG, and ATG were also elevated in hairdressers compared with all controls.
The calculated relative risk (RR) of contact allergy to PPD was approximately 5.4 higher for hairdressers, while the RR for ATG sensitization was 3.4 in hairdressers compared with consumers.
Commenting on these findings, James A. Yiannias, MD, professor of dermatology at the Mayo Medical School, Phoenix, told this news organization in an email that many providers and patients are concerned only about hair dye molecules such as PPD and aminophenol, as well as permanent, wave, and straightening chemicals such as GMTG.
“Although these are common allergens in hairdressers, allergens such as fragrances and some preservatives found in daily hair care products such as shampoos, conditioners, and hair sprays are also common causes of contact dermatitis,” said Dr. Yiannias, who wasn’t involved in the research.
Consequences of exposure
Dr. Yiannias explained that progressive worsening of the dermatitis can occur with ongoing allergen exposure and, if not properly mitigated, can lead to bigger issues. “Initial nuisances of mild irritation and hyperkeratosis can evolve to a state of fissuring with the risk of bleeding and significant pain,” he said.
But once severe and untreated dermatitis occurs, Dr. Yiannias said that hairdressers “may need to change careers” or at least face short- or long-term unemployment.
The researchers suggest reducing exposure to the allergen is key for prevention of symptoms, adding that adequate guidance on the safe use of new products is needed. Also, the researchers suggested that vocational schools should more rigorously implement education for hairdressers that addresses how to protect the skin appropriately at work.
“Hairdressers are taught during their training to be cautious about allergen exposure by avoiding touching high-risk ingredients such as hair dyes,” Dr. Yiannias added. “However, in practice, this is very difficult since the wearing of gloves can impair the tactile sensations that hairdressers often feel is essential in performing their job.”
The study received no industry funding. Dr. Yiannias reports no relevant financial relationships.

A 95-year-old White male with hypertension presented with itchy patches and bullae on the trunk and extremities
and is associated with various predisposing factors, including HLA genes, comorbidities, aging, and trigger factors such as drugs, trauma, radiation, chemotherapy, and infections. The autoimmune reaction is mediated by a dysregulation of T cells in which IgG and IgE autoantibodies form against hemidesmosomal proteins (BP180 and BP230). These autoantibodies induce neutrophil activation, recruitment, and degradation in the basement membrane of the skin.
Typically, patients present with intense pruritus followed by an urticarial or eczematous eruption. Tense blisters and bullae occur commonly on the trunk and extremities. Drug-associated bullous pemphigoid (DABP) is a common manifestation of the disease with histologic and immunologic features similar to those of the idiopathic version. Eruptions can be triggered by systemic or topical medications, and incidence of these reactions may be related to a genetic predisposition for the disease.
Some research suggests that drug-induced changes to the antigenic properties of the epidermal basement membrane result in an augmented immune response, while others point to structural modification in these zones that stimulate the immune system. Thiol- and phenol-based drugs have been largely implicated in the development of DABP because they are capable of structural modification and disruption of the dermo-epidermal junction in the basement membrane.
DABP often presents with patients taking multiple medications. Some of the most common medications are gliptins, PD-1 inhibitors, diuretics, antibiotics, anti-inflammatory drugs, and ACE-inhibitors, and other cardiovascular drugs. DABP may present with mucosal eruptions unlike its idiopathic counterpart that is mostly contained to the skin.
On this patient, two punch biopsies were taken. Histopathology revealed an eosinophil-rich subepidermal blister with a smooth epidermal undersurface consistent with bullous pemphigoid. Direct immunofluorescence was positive with a deposition of IgG and C3 at the epidermal side of salt split basement membrane zone.
Treatment for BP includes high potency topical and systemic steroids. Tetracyclines and niacinamide have been reported to improve the condition. Treatment is tailored to allow for cutaneous healing and control pruritus, but the physician must be mindful of the patient’s comorbidities and capacity for self-care. Prognosis is often better for DABP as withdrawal of the medication greatly accelerates clearance of the lesions. Worse prognosis is related to increased number of comorbidities and older age. Our patient’s BP is controlled currently with topical steroids and oral doxycycline.

Cutaneous SCC is the second most common skin cancer in the United States (after basal cell carcinoma) and increases in frequency with age and cumulative sun damage. It is the most common skin cancer in patients who are Black.
SCC is frequently found on the head and neck, including the ear, but is less commonly found within the conchal bowl (as seen here). Often, SCC manifests as a rough plaque or dome-shaped papule in a sun damaged location, but it may occasionally manifest as an ulcer. While most patients are cured with outpatient surgery, an estimated 8000 patients will develop nodal metastasis and 3000 patients will die from the disease in the United States annually.1 Chronically immunosuppressed patients, such as organ transplant recipients, are at high risk.
This patient underwent Mohs microsurgery (MMS) and clear margins were achieved after 2 stages. The resulting defect was repaired with a full-thickness graft from the postauricular fold. MMS is an excellent technique for keratinocyte carcinomas (SCC and basal cell carcinomas) of the head and neck, recurrent skin cancers on the trunk and extremities, high-risk cancer subtypes, and tumors with indistinct clinical borders. Follow-up for patients with SCCs includes full skin exams every 6 months for 2 years.

Genital HSV shedding declines rapidly in first year post infection
Shedding of genital herpes simplex virus was frequent soon after first-time infection but declined significantly during the first year, based on data from 82 individuals.
Genital herpes simplex virus (HSV) infections remain common and incurable; consequently, the population with residual infection continues to rise, Christine Johnston, MD, of the University of Washington, Seattle, and colleagues wrote. However, data on the viral shedding trajectory of genital HSV-1 are limited, although HSV-1 accounts for an increasing number of infections.
In a study published in JAMA the researchers recruited 82 women with first-episode genital HSV-1 infections from sexual health and primary care clinics in Seattle, between 2013 and 2018. The participants supplied self-collected oral and genital swabs for daily HSV polymerase chain reaction testing for two 30-day periods at 2 months and 11 months after their initial symptoms. The study population was not pregnant and did not have HIV infection. The median age of the participants was 26 years, 54 were women, and 42 had primary HSV-1 infections. Primary HSV-1 infection was defined as the lack of HSV antibody at baseline or an evolving antibody profile, based on the University of Washington HSV Western Blot.
The primary outcome was the rates of genital and oral HSV shedding and lesions at 2 and 11 months and up to 2 years after an initial HSV-1 infection.
At 2 months, approximately two-thirds (64.6%) of the participants had HSV-1 in the genital tract and 29.3% had virus in the mouth. Genital shedding of HSV-1 was detected in 12.1% of 2,264 total testing days at 2 months, but this rate declined to 7.1% of 1,719 testing days at 11 months (relative risk, 0.52).
The researchers identified oral HSV-1 shedding on 3.9% of 2,247 testing days at 2 months, with a slight increase to 5.1% of 1,714 testing days at 11 months.
Both genital and oral lesions were rare, with reports of 2.6% and 0.4%, respectively, at 2 months and 3.8% and 0.5%, respectively, at 11 months.
The risk of genital shedding was significantly higher in individuals with primary HSV-1, compared with those with nonprimary infections (7.9% vs. 2.9%; RR, 2.75). The overall rate of genital shedding was 17.2% for those with primary HSV-1, of which 15.2% was asymptomatic. Oral shedding was similar for individuals with primary and nonprimary HSV in a multivariate analysis.
In addition, HSV-specific CD4+ and CD8+ T-cell responses were identified in all participants, and these remained stable during the study period. No association appeared between rates of genital and oral shedding and the proportion of cells that expressed two, three, or four cytokines.
The current study is the first known to comprehensively assess genital and oral HSV-1 viral shedding using polymerase chain reaction, the researchers wrote. “Characterizing shedding rates is clinically important because patients with genital herpes are often concerned about transmission to sexual partners, which usually occurs in the absence of lesions.”
The study findings were limited by several factors including the 22% loss of participants to follow-up by the end of the first year, and the use of data from a single location with a primarily White population, the researchers noted. Another limitation was reliance on self-reports and the potential underestimation of recurrences because of the possible use of antiviral medications between swabbing periods.
However, the results indicate the early frequency of HSV-1 shedding and suggest that suppressive therapy might benefit individuals with primary HSV-1 during their first year of infection, the researchers said.
Findings may improve HSV management
The current study helps fill a knowledge gap regarding the natural history of genital HSV-1 infections, Richard J. Whitley, MD, and Edward W. Hook III, MD, both of the University of Alabama at Birmingham, wrote in an accompanying editorial. Despite the small study population, the data represent the largest cohort to date of individuals with first-episode infection and up to 2 years’ follow-up.
Although HSV-2 shedding is greater and associated with more symptoms, seroprevalence of HSV-2 in the United States is declining, they noted. Therefore, the findings can inform patient counseling and recommendations for antiviral therapy that may extend to managing HSV-1 in pregnant women as well, although no pregnant women were included in the study.
“For clinicians, these data emphasize the importance of determining the HSV viral type in persons presenting with initial episodes of genital herpes to accurately counsel patients regarding risk of clinical recurrence, the likelihood of asymptomatic shedding of virus and hence transmission, and antiviral prophylaxis,” the editorialists emphasized. For investigators, the results should prompt additional studies of the host defense against HSV and improved serological testing.
Study supports need for attention to HSV-1
“Genital herpes is an extremely common sexually transmitted infection, and often only HSV-2 is measured,” Sarah W. Prager, MD, of the University of Washington, Seattle, said in an interview. “This study shows that HSV-1 also accounts for a significant amount of genital disease, and should also be considered when determining prevalence of genital herpes.
“I was not surprised to see that viral shedding decreased significantly over the first year after diagnosis, and similarly not surprised that lesions were rare after the initial infection,” said Dr. Prager, who was not involved in the study. “I was somewhat surprised to see that genital HSV-1 shedding was more common than oral shedding.”
Dr. Prager said that she would advise clinicians against serum HSV testing unless someone has an active genital lesion. “Testing after a lesion will often reveal HSV-1, and patients should be counseled that shedding will decrease over the first year. Subsequent genital lesions are uncommon, but certainly possible, and oral lesions and shedding are both rare.” ]
More research is needed in a more diverse population, Dr. Prager emphasized. Following patients for more than a year and learning more about the use of antiviral medications also would be useful.
The study was supported in part by the National Institutes of Health/National Institute of Allergy and Infectious Diseases through grants to several authors, including lead author Dr. Johnston. Dr. Johnston also disclosed personal fees from AbbVie, grants from Gilead, royalties from UpToDate, and personal fees from GlaxoSmithKline unrelated to the current study.

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

“I think we were seeing this clinically, but to see it in a clinical trial gives us more confidence in discussing with parents,” said session moderator Melinda Gooderham, MD, assistant professor at Queens University, Kingston, Ont., and medical director at the SKiN Centre for Dermatology in Peterborough.
What she also took away from the study was safety of these treatments. “The discontinuation rate was not different with either drug, so it’s not like ciclosporin works fast but all these people have problems and discontinue,” Dr. Gooderham told this news organization. “That’s also reassuring.”
Asked which treatment she prefers, Dr. Gooderham, a consultant physician at Peterborough Regional Health Centre, picked methotrexate “because of the lasting effect. But there are times when you may need more rapid control ... where I might choose ciclosporin first, but for me it’s maybe 90% methotrexate first, 10% ciclosporin.”
Dr. Flohr and Dr. Gooderham report no relevant financial relationships. The study was funded by the National Institute for Health and Care Research.

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

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

An integrative approach to atopic dermatitis features a long list of options
to probiotics and acupressure – that he encourages patients to try as they use the big guns, or as they attempt to wean off of them or avoid their use altogether.
During a presentation at the annual Integrative Dermatology Symposium, Dr. Lio said that he uses “5 pillars” to guide his integrative treatment plans: The skin barrier, the psyche, the microbiome, inflammation, and itch. “I try to flag approaches that predominantly address the categories that I think need the most help,” he said. “And I tell patients [which pillar or pillars] each treatment is addressing.”
Most commonly, the greatest challenge with AD – and the “single biggest weakness of conventional Western medicine” – lies not with getting patients clear in the first place, but in keeping them clear safely, he said. “I don’t think that using immunosuppressive [medications] is okay for the long-term unless there is no other choice,” said Dr. Lio, who cofounded the Chicago Integrative Eczema Center about 6 years ago and is clinical assistant professor of dermatology and pediatrics at Northwestern University, Chicago. Oftentimes, he said, complementary approaches, including dietary changes, can also serve as supportive adjunctive therapy to biologics and JAK inhibitors.
He has three main criteria, or “filters,” for evaluating these treatments before recommending them to patients: At least some clinical evidence for efficacy (preferably randomized trials but not necessarily), safety, and practicality. The “only way we’re going to move things forward [for AD and other conditions] is to try out less tested treatments ... to open up to them,” Dr. Lio said in an interview after the meeting. And in doing so, he said, dermatologists “can connect with a lot of patients whom naysayers can’t connect with.”
An integrative menu
Dr. Lio individualizes plans, suggesting treatments after “listening to patients’ stories” and considering their age, history, symptoms and skin presentation, and other factors. He said he “goes little by little,” telling a patient, for instance, “I’d love for us to try adding a little hemp oil to your diet.”
If patients aren’t pleased with or are tired of treatments, he said in the interview, “we move on and try something else.”
At the meeting, he described some of the treatments on his menu and the supporting evidence for those treatments:
Oral hempseed oil. A randomized crossover study of 20 adult patients with AD found that daily consumption of 2 tablespoons of hempseed oil decreased skin dryness, itchiness, and use of topical medications compared with consumption of olive oil. “It was statistically significant and seemed clinically meaningful,” likely resulting from the high concentration of polyunsaturated fatty acids in the oil, Dr. Lio said.
Topical vitamin B12. In a phase 3 randomized controlled trial of topical B12 applied twice a day for 8 weeks, patients experienced significant improvements in the extent and severity of AD compared with placebo. Another study in children with AD aged 6 months to 18 years found significant improvement in as early as 2 weeks of use. “It really does help, and is very gentle in babies,” Dr. Lio said.
Black tea compresses. “It’s absolutely my favorite kind of compress,” he said. “It was studied on the face and eyelids but I use it all over the body for adults and kids.” A German study of 22 patients with AD or contact facial dermatitis showed significant improvements in facial dermatitis within the first 3 days of treatment with application of black tea dressings plus an emollient cream, with significant reductions in four disease activity scores (the Facial Eczema Area and Severity Index, visual analog scale for pruritus, Investigator’s Global Assessment score, and Patient’s Self-Assessment Score) that continued through day 6.
Oolong tea. In a 2001 study, after 1 month of drinking oolong tea after each meal, 64% of patients with recalcitrant AD who continued with their regular treatment showed marked to moderate improvements in AD, with a beneficial effect first noticed after 1-2 weeks. At 6 months, 54% still had a good response to treatment. “It’s super cheap and accessible,” Dr. Lio said.
Coconut oil. One of the greatest benefits of coconut oil is on the microbiome and the dysbiosis that can result from a disrupted, or “leaky,” skin barrier – especially overgrowth of Staphylococcus aureus, which “drives AD,” Dr. Lio said. In a study of adults with AD from the Philippines, topically applied coconut oil decreased S. aureus colonization by 95% when applied twice daily for 4 weeks, compared with a 50% decrease in an olive oil control group. Other research has shown coconut oil to be superior to mineral oil as a moisturizer, he said at the meeting.
Acupressure. After a pilot study conducted by Dr. Lio and colleagues showed greater decreases in itch (per the visual analogue scale) in adults with AD who applied an acupressure bead at the LI11 point (near the elbow) for 3 minutes three times a week for 4 weeks, than among those who did not use the acupressure tool, Dr. Lio began trying it with some of his patients. “Now I use it broadly,” he added in the interview. “Kids over 10 can figure out how to use it and teenagers love it [to relief itch]. Some don’t use the beads anymore, they just use their fingertips.”
Advice on diet, vitamin D, and probiotics
AD severity is “powerfully” correlated with IgE food allergy, but Dr. Lio said at the meeting that he currently takes a cautious approach toward strict elimination diets.
There is a growing school of thought among allergists, he said, that positive IgE tests without evidence of acute reactions may not indicate true allergy, but rather sensitivity – and may not warrant food eliminations. And as has been shown with peanuts, there can be a serious downside to elimination, as food avoidance can lead to serious allergy later on, he said.
“More and more people are thinking that if you can tolerate [a food], continue it,” he added in the interview. In the absence of clear reactions, the only way to really know if a food is making eczema worse is to do a double-blind, placebo-controlled food challenge test, he noted.
Patients often come to see him believing that food is the “root cause” of their eczema and feeling frustrated, even anxious, about strict dietary restrictions they’ve implemented. But for many of these patients, the right question “would be to ask, why is my eczema causing my food allergy?” he said at the meeting, referring to the epithelial barrier hypothesis, which posits that skin barrier dysfunction can lead to asthma, allergic rhinitis, and food allergy.
Dr. Lio often recommends the Autoimmune Protocol (AIP) diet, a “close cousin” of the paleo diet for patients with AD, as general guidance to be followed “holistically” and often without the strict eliminations it prescribes. Minimizing processed foods and dairy and grains, which “can be inflammatory in some people,” and focusing on whole, nutrient-rich foods – all in keeping with the AIP principles – should have positive effects on the microbiome, overall health, and likely AD as well, he said.
Across the board, Dr. Lio recommends vitamin D (at nationally recommended dosages) and probiotics. Vitamin D has been shown to significantly help a small percentage of patients with eczema, he said, so he advises patients that it’s worth a trial. “I tell patients that I don’t know how to pick that small group out, so let’s try for a few months and see,” he said. “Inevitably, a percentage of patients come back and say it makes a huge difference.”
Dr. Lio’s understanding and use of probiotics has been “dynamic” over the years. “The “best, most reliable evidence” that probiotics can improve AD symptoms comes with the use of multiple probiotic strains together, he said. Based on limited but growing literature, he ensures that recommended formulations for babies include Lactobacillus rhamnosus, and that formulations for adults include Lactobacillus salivarius.
Dr. Lio works closely with dietitians, hypnotherapists, and psychologists – and will occasionally refer interested patients with AD to a Chinese medicine practitioner who personalizes the use of herbal formulations.
He reported no relevant disclosures.

Most commonly, the greatest challenge with AD – and the “single biggest weakness of conventional Western medicine” – lies not with getting patients clear in the first place, but in keeping them clear safely, he said. “I don’t think that using immunosuppressive [medications] is okay for the long-term unless there is no other choice,” said Dr. Lio, who cofounded the Chicago Integrative Eczema Center about 6 years ago and is clinical assistant professor of dermatology and pediatrics at Northwestern University, Chicago. Oftentimes, he said, complementary approaches, including dietary changes, can also serve as supportive adjunctive therapy to biologics and JAK inhibitors.
He has three main criteria, or “filters,” for evaluating these treatments before recommending them to patients: At least some clinical evidence for efficacy (preferably randomized trials but not necessarily), safety, and practicality. The “only way we’re going to move things forward [for AD and other conditions] is to try out less tested treatments ... to open up to them,” Dr. Lio said in an interview after the meeting. And in doing so, he said, dermatologists “can connect with a lot of patients whom naysayers can’t connect with.”
An integrative menu
Dr. Lio individualizes plans, suggesting treatments after “listening to patients’ stories” and considering their age, history, symptoms and skin presentation, and other factors. He said he “goes little by little,” telling a patient, for instance, “I’d love for us to try adding a little hemp oil to your diet.”
If patients aren’t pleased with or are tired of treatments, he said in the interview, “we move on and try something else.”
At the meeting, he described some of the treatments on his menu and the supporting evidence for those treatments:
Oral hempseed oil. A randomized crossover study of 20 adult patients with AD found that daily consumption of 2 tablespoons of hempseed oil decreased skin dryness, itchiness, and use of topical medications compared with consumption of olive oil. “It was statistically significant and seemed clinically meaningful,” likely resulting from the high concentration of polyunsaturated fatty acids in the oil, Dr. Lio said.
Topical vitamin B12. In a phase 3 randomized controlled trial of topical B12 applied twice a day for 8 weeks, patients experienced significant improvements in the extent and severity of AD compared with placebo. Another study in children with AD aged 6 months to 18 years found significant improvement in as early as 2 weeks of use. “It really does help, and is very gentle in babies,” Dr. Lio said.
Black tea compresses. “It’s absolutely my favorite kind of compress,” he said. “It was studied on the face and eyelids but I use it all over the body for adults and kids.” A German study of 22 patients with AD or contact facial dermatitis showed significant improvements in facial dermatitis within the first 3 days of treatment with application of black tea dressings plus an emollient cream, with significant reductions in four disease activity scores (the Facial Eczema Area and Severity Index, visual analog scale for pruritus, Investigator’s Global Assessment score, and Patient’s Self-Assessment Score) that continued through day 6.
Oolong tea. In a 2001 study, after 1 month of drinking oolong tea after each meal, 64% of patients with recalcitrant AD who continued with their regular treatment showed marked to moderate improvements in AD, with a beneficial effect first noticed after 1-2 weeks. At 6 months, 54% still had a good response to treatment. “It’s super cheap and accessible,” Dr. Lio said.
Coconut oil. One of the greatest benefits of coconut oil is on the microbiome and the dysbiosis that can result from a disrupted, or “leaky,” skin barrier – especially overgrowth of Staphylococcus aureus, which “drives AD,” Dr. Lio said. In a study of adults with AD from the Philippines, topically applied coconut oil decreased S. aureus colonization by 95% when applied twice daily for 4 weeks, compared with a 50% decrease in an olive oil control group. Other research has shown coconut oil to be superior to mineral oil as a moisturizer, he said at the meeting.
Acupressure. After a pilot study conducted by Dr. Lio and colleagues showed greater decreases in itch (per the visual analogue scale) in adults with AD who applied an acupressure bead at the LI11 point (near the elbow) for 3 minutes three times a week for 4 weeks, than among those who did not use the acupressure tool, Dr. Lio began trying it with some of his patients. “Now I use it broadly,” he added in the interview. “Kids over 10 can figure out how to use it and teenagers love it [to relief itch]. Some don’t use the beads anymore, they just use their fingertips.”
Advice on diet, vitamin D, and probiotics
AD severity is “powerfully” correlated with IgE food allergy, but Dr. Lio said at the meeting that he currently takes a cautious approach toward strict elimination diets.
There is a growing school of thought among allergists, he said, that positive IgE tests without evidence of acute reactions may not indicate true allergy, but rather sensitivity – and may not warrant food eliminations. And as has been shown with peanuts, there can be a serious downside to elimination, as food avoidance can lead to serious allergy later on, he said.
“More and more people are thinking that if you can tolerate [a food], continue it,” he added in the interview. In the absence of clear reactions, the only way to really know if a food is making eczema worse is to do a double-blind, placebo-controlled food challenge test, he noted.
Patients often come to see him believing that food is the “root cause” of their eczema and feeling frustrated, even anxious, about strict dietary restrictions they’ve implemented. But for many of these patients, the right question “would be to ask, why is my eczema causing my food allergy?” he said at the meeting, referring to the epithelial barrier hypothesis, which posits that skin barrier dysfunction can lead to asthma, allergic rhinitis, and food allergy.
Dr. Lio often recommends the Autoimmune Protocol (AIP) diet, a “close cousin” of the paleo diet for patients with AD, as general guidance to be followed “holistically” and often without the strict eliminations it prescribes. Minimizing processed foods and dairy and grains, which “can be inflammatory in some people,” and focusing on whole, nutrient-rich foods – all in keeping with the AIP principles – should have positive effects on the microbiome, overall health, and likely AD as well, he said.
Across the board, Dr. Lio recommends vitamin D (at nationally recommended dosages) and probiotics. Vitamin D has been shown to significantly help a small percentage of patients with eczema, he said, so he advises patients that it’s worth a trial. “I tell patients that I don’t know how to pick that small group out, so let’s try for a few months and see,” he said. “Inevitably, a percentage of patients come back and say it makes a huge difference.”
Dr. Lio’s understanding and use of probiotics has been “dynamic” over the years. “The “best, most reliable evidence” that probiotics can improve AD symptoms comes with the use of multiple probiotic strains together, he said. Based on limited but growing literature, he ensures that recommended formulations for babies include Lactobacillus rhamnosus, and that formulations for adults include Lactobacillus salivarius.
Dr. Lio works closely with dietitians, hypnotherapists, and psychologists – and will occasionally refer interested patients with AD to a Chinese medicine practitioner who personalizes the use of herbal formulations.
