Efficacy of moisturizers in paediatric atopic dermatitis: A systematic review and meta-analysis of randomised controlled trials

Abstract

Background: Topical moisturizer is recommended for atopic dermatitis. Aims: The aim of the study was to investigate the knowledge gap regarding the efficacy of moisturizer in young patients. Methods: A systematic review and meta-analysis were conducted on randomised controlled trials comparing participant’s ≤15 years with atopic dermatitis, receiving either topical moisturizer or no moisturizer treatment. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework. Results: Six trials were included (intervention n= 436; control n= 312). Moisturizer use extended time to flare by 13.52 days (95% confidence interval 0.05–26.99, I2 88%). Greater reduction in risk of relapse was observed during the first month of latency (pooled risk ratio 0.47, 95% confidence interval 0.31–0.72, I2 28%) compared to the second and third months (pooled risk ratio 0.65, 95% confidence interval 0.47–0.91, I2 35% and pooled risk ratio 0.63, 95% confidence interval 0.47–0.83, I2 33%, respectively).Treated patients were 2.68 times more likely to experience a three–six months remission (95% confidence interval1.18–6.09, I2 56%). Moisturizer minimally improved disease severity and quality of life. Limitations: There is a dire need to conduct randomised controlled trials with more robust and standardised designs. Conclusion: Moisturizer benefits young patients with atopic dermatitis. However, more research is needed to better estimate its efficacy. © 2022 Indian Journal of Dermatology, Venereology and Leprology - Published by Scientific Scholar
