BackgroundTo assess the efficacy and safety of upadacitinib in adolescents with moderate-to-severe atopic dermatitis (AD).MethodsA comprehensive search was conducted using PubMed, Medline, Embase, Web of Science, Clinical Trials Website, and Cochrane Library databases, spanning from their inception until February 18, 2024. The review incorporated all randomized controlled trials examining upadacitinib's efficacy in managing moderate to severe AD among adolescent patients. The methodological quality of the selected studies underwent thorough assessment utilizing the Cochrane systematic review methodology. Statistical analyses of the outcome measures were executed employing the Review Manager 5.3 software.ResultsThe meta-analysis encompassed 4 studies in total. Compared to placebo, upadacitinib at doses of both 15 and 30 mg was associated with a significant enhancement in the eczema area and severity index-75% ([odds ratio, OR = 11.06, 95% confidence interval, CI (6.78-18.04), P < .00001]; [OR = 21.73, 95% CI (12.73-37.11), P < .00001]), a reduction in the numerical rating scale of ≥4 ([OR = 6.16, 95% CI (3.56-10.64), P < .00001]; [OR = 10.58, 95% CI (6.12-18.29), P < .00001]), and improvement in the investigator's global assessment to 0/1 ([OR = 8.85, 95% CI (4.86-16.10), P < .00001]; [OR = 21.43, 95% CI (11.64-39.46), P < .00001]). Regarding safety, upadacitinib at both 15 and 30 mg doses was linked to a statistically significant rise in the overall incidence of adverse events when juxtaposed with placebo ([OR = 1.57, 95% CI (1.01-2.44), P = .04]; [OR = 2.21, 95% CI (1.44-3.41), P = .0003]). Nevertheless, no statistically significant disparity was discovered in the occurrence of serious adverse events between upadacitinib and placebo ([OR = 1.02, 95% CI (0.27-3.84), P = .98]; [OR = 0.42, 95% CI (0.09-1.93), P = .26]).ConclusionThe findings from this meta-analysis indicate that upadacitinib demonstrates substantial effectiveness and tolerability in treating moderate to severe AD in adolescents. Moreover, upadacitinib provides a rapid reduction in pruritus and markedly ameliorates symptoms and signs, with the 30 mg dosage showing a more pronounced therapeutic effect relative to the 15 mg dosage.Copyright © 2024 the Author(s).
