RESUMO
OBJECTIVE: To evaluate the efficacy and safety of upadacitinib in the treatment of moderate-to-severe atopic dermatitis (AD), and provide reference for rational clinical medication. METHODS: PubMed, Medline, Embase, Web of Science, Clinical Trials Website, and Cochrane Library databases were searched from the time of establishment until January 6, 2024, to compile a list of all randomized controlled trials (RCTs) including upadacitinib in the treatment of moderate-to-severe AD. The quality of the included studies was evaluated using the Cochrane Systematic Review. Review Manager 5.3 software was utilized for statistical analysis of outcome measures. RESULTS: A total of five studies were included in the meta-analysis. The results revealed that the 15 mg and 30 mg upadacitinib significantly improved Eczema Area and Severity Index (EASI) 75% {[Odds Ratio (OR) = 8.58, 95% confidence interval (CI) (5.84-12.60), P < 0.00001] [OR = 15.62, 95% CI (10.89-22.42), P < 0.00001]}, Numerical Rating Scale (NRS) ≥ 4 {[OR = 7.13, 95% CI (5.63-9.01), P < 0.00001] [OR = 11.30, 95% CI (8.93-14.31), P < 0.00001]}, and Investigator's Global Assessment (IGA) 0/1 {[OR = 8.63, 95% CI (6.60-11.27), P < 0.00001] [OR = 16.04, 95% CI (12.26-20.99), P < 0.00001]} compared to placebo. In terms of safety, although 15 mg and 30 mg upadacitinib significantly increased the overall adverse events rate compared to placebo {[OR = 1.31, 95% CI (1.09-1.58), P = 0.004] [OR = 1.85, 95% CI (1.54-2.21), P < 0.00001]}, there was no significant difference in the serious adverse events rate {[OR = 0.73, 95% CI (0.41-1.29), P = 0.28] [OR = 0.69, 95% CI (0.39-1.23), P = 0.21]} and withdrawal rate due to adverse events {[OR = 0.66, 95% CI (0.39-1.11), P = 0.12] [OR = 0.85, 95% CI (0.52-1.38), P = 0.50]} compared to placebo. CONCLUSION: This meta-analysis preliminarily suggests that upadacitinib is effective and safe for usage in the treatment of moderate-to-severe AD. Additionally, upadacitinib can instantly relieve itchiness and effectively reduce symptoms and signs, with its 30-mg dose being more effective than the 15-mg dose.
