Real-World Effectiveness and Safety of JAK Inhibitors in Atopic Dermatitis: A Systematic Review and Meta-Analysis
Abstract
OBJECTIVE: The aim of this study is to evaluate the effectiveness and safety of JAK inhibitors in patients with moderate to severe atopic dermatitis by performing a systematic review and meta-analysis using data from studies in real-world settings.
DESIGN: Systematic review and meta-analysis. Pooled estimates for effectiveness and safety were assessed using the Freeman-Tukey Double ArcSine method. Statistical heterogeneity was assessed using I2 statistics. A random-effects model (DerSimonian-Laird method) was applied to consider the heterogeneity within and between studies and to give a more conservative estimate. The study quality assessment tools developed by the National Heart, Lung, and Blood Institute were used.
DATA SOURCE: Relevant studies were searched in March 2025 using four databases: PubMed, Embase, Scopus, and Web of Science.
ELIGIBILITY CRITERIA: Studies evaluating the effectiveness or safety of systemic JAK inhibitors among patients with moderate to severe atopic dermatitis in a real-world setting were included.
RESULTS: A total of 50 studies were included in this review. Regarding their effectiveness, the pooled estimates with a 95% CI of Eczema Area and Severity Index (EASI)-75 were 44% (34%-55%), 45% (28%-62%), 59% (51%-66%), 73% (64%-81%), 70% (57%-81%), and 86% (72%-96%) at 4, 8, 12, 16, 24, and 52 weeks. For safety, the most common adverse events were acne (16%), followed by increased creatine phosphokinase levels (13%) and increased lipids (12%).…
