Introduction: Recent studies have confirmed the possibility of using upadacitinib for treating atopic dermatitis (AD). However, there is no meta-analysis to summarize and quantify the efficacy and safety of the drug, especially for adolescents with AD.
Aim: To evaluate the overall efficacy and safety of upadacitinib in adults and adolescents with AD.
Material and methods: We developed this systematic review and meta-analysis according to PRISMA guidelines. Risk-of-bias assessment tool, RoB2 (revised version 2019) was used for quality assessment.
Results: Four RCTs were enrolled in the analysis, 3 of which on both adults and adolescents, while the other on adults only. For either adults or adolescents, the group treated with upadacitinib all had better performance than controls: EASI-75 (adults): RR = 4.68, 95% CI: 4.09, 5.35; NRS4 (adults): RR = 4.07, 95% CI: 3.15, 5.25; EASI-75 (adolescents): RR = 4.16, 95% CI: 2.70, 6.42; NRS4 (adolescents): RR = 4.52, 95% CI: 2.49, 8.21. Furthermore, upadacitinib 30 mg was more effective than 15 mg. For serious AEs, upper respiratory tract infection and headache, there was no significant difference between the upadacitinib group and controls. However, the treatment of upadacitinib may increase the risk of nasopharyngitis, increase blood creatine phosphokinase and cause acne.
Conclusions: Upadacitinib seems to be a promising drug for AD. More long-term and larger-sized randomized clinical trials are required to further assess the safety and efficacy of upadacitinib for AD.
