Severe and ChRonic Atopic dermatitis Treatment CoHort (SCRATCH): A Danish Real-world Evidence Atopic Dermatitis Treatment Registry.

Data from real-world use of new systemic treatments in atopic dermatitis (AD) is important for assessing safety and efficacy. The aim of this study is to describe the baseline characteristics of adult patients with moderate-to-severe AD enrolled in the Danish nationwide Severe and ChRonic Atopic dermatitis Treatment CoHort (SCRATCH) database, between October 2017 and August 2021. A total of 282 adult patients were included. Most (62%) were men, the median age at baseline was 43 years (interquartile range (IQR) 29-54 years), and median age at onset of AD was 1 year (IQR 0-6 years). The median Eczema Area and Severity Index at treatment initiation was 19.1 (IQR 11.9-25.7); median Patient Oriented Eczema Measure 21.0 (IQR 16.0-25.0); median Dermatology Life Quality Index 13.0 (IQR 7.0-19.0); and median itch and sleep numerical rating scale scores 8.0 (IQR 6.0-9.0) and 6.0 (IQR 4.0-8.0). Differences were found between the sexes. This registry will provide a source for future efficacy and safety studies.

Bidirectional association between atopic dermatitis, conjunctivitis, and other ocular surface diseases: A systematic review and meta-analysis.

BACKGROUND: Conjunctivitis and several other ocular surface diseases (OSDs) have been linked to atopic dermatitis (AD) and its treatment. OBJECTIVES: To examine the association between AD, conjunctivitis, and other OSDs. METHODS: A systematic review and meta-analysis was performed. Two authors independently searched EMBASE, PubMed, SCOPUS, and Web of Science and performed title/abstract and full-text review and data abstraction. Pooled random-effects prevalence and odds ratios (ORs) with 95% confidence intervals (CIs) were estimated. RESULTS: The search yielded 5719 nonduplicate articles; 134 were included in the quantitative analysis. AD was associated with conjunctivitis compared to reference individuals (OR, 2.78; 95% CI, 2.33-3.32); the prevalences of conjunctivitis in patients with AD and reference individuals were 31.7% (95% CI, 27.7-35.9) and 13.3% (95% CI, 11.0-15.7), respectively. Keratoconus (OR, 3.71; 95% CI, 1.99-6.94) and ocular herpes simplex (OR, 3.65; 95% CI 2.04-6.51) were also associated with AD. LIMITATIONS: Disease definitions differed and often relied on self-reports. Few studies provided data concerning AD phenotype or OSDs other than conjunctivitis. CONCLUSIONS: Conjunctivitis is the most common ocular comorbidity in AD. Signs and symptoms of conjunctivitis and other OSDs in AD may be underreported, making proactive inquiry and examination by physicians treating patients with AD important.
