European Task Force on Atopic Dermatitis statement on severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infection and atopic dermatitis Atopic dermatitis (AD) is a complex disease with elevated risk of respiratory comorbidities.[[1]] Severely affected patients are often treated with immune-modulating systemic drugs.[[3]] On 11 March 2020, the World Health Organization declared the 2019 novel coronavirus severe acute respiratory syndrome (SARS-Cov-2) epidemic to be a pandemic. If systemic treatment of AD needs to be paused, patients should be supplied with ample topical therapy and guidance on the amount needed to prevent flares until systemic therapy can be reinstated.

Background: Phototherapy is used to treat atopic dermatitis (AD). Evidence for its efficacy, impact on quality of life, cost‐effectiveness and short‐ and long‐term safety with real‐life usage is weak. Objectives: We established a taskforce to examine how phototherapy is currently being used as a treatment for AD across the United Kingdom and Europe to inform our understanding and guide future research into management of patients with AD using UV‐based phototherapies. Methods: An anonymous electronic multiple‐response survey exploring phototherapy prescribing practices and experience of phototherapy modalities was developed by the study authors and sent to members of phototherapy networks from the United Kingdom and Europe. Responses were received between February and July 2021. Results: About 144 respondents from 27 European countries completed the survey. NBUVB was the most widely used [n = 138 (96%)]. Home‐based NBUVB was available in 8/27 countries (25/144 respondents, 17%). Oral psoralen‐UVA (PUVA) was more widely available than bath PUVA (n = 106, 74% vs. n = 60, 42%) and used mainly in adult patients. 49/144 (34%) of respondents had access to UVA1. Phototherapy would be considered instead of systemic treatment in 96% of adults and 82% of children for NBUVB, versus 40% of adults and 3% of children for PUVA. Starting doses, standard dosing increments, length of treatment courses, lifetime limits for treatments and thresholds for performing annual skin assessments varied between responders. Conclusions: NBUVB was the most widely used phototherapy for AD in adult and paediatric patients, while PUVA and UVA1 were less used. Prescribing practices varied considerably, highlighting the lack of consensus practice in many different aspects of phototherapy for the treatment of AD in children and adults. This indicates that further studies are required to determine optimal phototherapeutic regimens for AD and informs our understanding of parameters that should be included in future high‐quality randomized controlled trials (RCT) of phototherapy.

Atopic dermatitis (AD) and food allergy (FA) share similar type 2 inflammation and commonly co‐occur, but the precise proportion of AD patients with FA and vice versa, as well as the effect of AD disease severity on the strength of this association remains uncertain. The aim of this comprehensive systematic review and meta‐analysis was to determine the prevalence and bidirectional associations of AD with food sensitivity (FS), FA and challenge‐proven food allergy (CPFA). We searched PubMed and EMBASE and three independent reviewers performed title/abstract and full‐text review and data extraction. Overall, 557 articles (n = 225,568 individuals with AD, n = 1,128,322 reference individuals; n = 1,357,793 individuals with FS, FA or CPFA, n = 1,244,596 reference individuals) were included in quantitative analyses. The overall pooled prevalence of FS, FA and CPFA in individuals with AD were 48.4% (95% confidence interval: 43.7–53.2), 32.7% (28.8–36.6) and 40.7% (34.1–47.5) respectively. AD prevalence among individuals with FS, FA and CPFA were 51.2% (46.3–56.2), 45.3% (41.4–49.3) and 54.9% (47.0–62.8) respectively. Children with AD had higher pooled FS (49.8% (44.4–55.1)) and FA (31.4% (26.9–36.1)) prevalences than adults with AD (28.6% (13.4–46.8) and 24.1% (12.1–38.7) respectively). Prevalences of FS and FA numerically increased with AD severity. FS, FA and CPFA are common comorbidities of AD and are closely related. Physicians should be attentive to this relationship to optimize management and treatment strategies in patients. [ABSTRACT FROM AUTHOR]

How to integrate atopic dermatitis in the management of skin neglected tropical diseases in Sub-Saharan Africa? However, NTDs represent only 2%-4% of all skin diseases in SSA.[1] Geographical and financial hurdles make skin NTDs in SSA diseases of poverty affecting underserved people. Itch is a common denominator between skin NTDs, such as scabies and skin non NTDs such as AD. [Extracted from the article]

Background: Chronic inflammatory skin diseases such as atopic dermatitis (AD) and psoriasis (PSO) present major challenges in health care. Thus, biomarkers to identify disease trajectories and response to treatments to improve the lives of affected individuals warrant great research consideration. The requirements that these biomarkers must fulfil for use as practical clinical tools have not yet been adequately investigated. Aim: To identify the core elements of high‐quality AD and PSO biomarkers to prepare recommendations for current biomarker research. Method: A cross‐sectional two‐round Delphi survey was conducted from August to October 2019 and October to November 2020. All participants were members of the BIOMAP project, an EU‐funded consortium of clinicians, researchers, patient organizations and pharmaceutical industry partners. The first round consisted of three open‐ended questions. Responses were qualitatively analysed, and 26 closed statements were developed. For the second round, 'agreement' was assumed when the responses of ≥70% of the participants were ≥5 points on a 7‐point Likert scale for each statement. Priority classification was based on mean scores (<20th percentile = low, 20th to 60th percentile = medium, >60th percentile = high). Results: Twenty‐one and twenty‐six individuals participated in rounds one and two, respectively. From 26 statements that were included in round 2, 18 achieved agreement (8 concerning the performance, 8 for the purpose and 2 on current obstacles). Seven statements were classified as high priority, e.g. those concerning reliability, clinical validity, a high positive predictive value, prediction of the therapeutic response and disease progression. Another seven statements were assigned medium priority, e.g. those about analytical validity, prediction of comorbidities and therapeutic algorithm. Low priority included four statements, like those concerning cost effectiveness and prediction of disease flares. Conclusion: The core requirements that experts agreed on being essential for high‐quality AD and PSO biomarkers require rapid validation. Biomarkers can therefore be assessed based on these prioritized requirements. [ABSTRACT FROM AUTHOR]

Atopic dermatitis (AD) is a common inflammatory skin disease that affects both children and adults, including a large number of adults of reproductive age. Several guidelines for the treatment of AD exist, yet specific recommendations for the treatment of pregnant or lactating women and for adults planning to have a child are often lacking. This position paper from the European Task force on Atopic Dermatitis (ETFAD) is based on up‐to‐date scientific literature on treating pregnant and lactating women as wells as adults with AD planning to have a child. It is based on the expert opinions of members of the ETFAD and on existing safety data on the proposed treatments, many of which are derived from patients with other inflammatory diseases or from transplantation medicine. For treating future parents, as well as pregnant and lactating women with AD, the use of topical treatments including moisturizers, topical corticosteroids, tacrolimus, antiseptics such as chlorhexidine, octenidine, potassium permanganate and sodium hypochlorite (bleach) is deemed to be safe. Ultraviolet (UV) therapy may also be used. Systemic treatment should be prescribed only after careful consideration. According to the opinion of the ETFAD, treatment should be restricted to systemic corticosteroids and cyclosporine A, and, in selected cases, azathioprine. [ABSTRACT FROM AUTHOR]
