Evaluating the effectiveness of systemic corticosteroids to mitigate relapse in children assessed and treated for acute asthma: A network meta-analysis.

OBJECTIVE: The objective of this systematic review was to explore the effectiveness of various systemic corticosteroid (SCS) regimens to mitigate relapse in children with asthma discharged from an acute care setting. DATA SOURCES: Medline, EMBASE, Global Health, International Pharmaceutical Abstracts, EMB ALL, CINAHL, SCOPUS, Proquest Dissertations and Theses Global, and LILACS were searched using controlled vocabulary and key words. Additional citations were searched via clinical trial registries, Google Scholar, bibliographies, a SCOPUS forward search of a sentinel paper, and hand searching conference abstracts. STUDY SELECTION: No limitations based on language, publication status, or year of publication were applied. Two independent reviewers searched to identify randomized controlled trials comparing the effectiveness of SCS regimens to prevent relapse in children following treatment for acute asthma. RESULTS: Fifteen studies were included. In three studies comparing SCS to placebo, asthma relapse was significantly reduced (RR = 0.10; 95% CI: 0.01, 0.77; I CONCLUSION: This review found evidence that SCS corticosteroids reduce relapse in children following treatment for acute asthma, albeit based on a limited number of studies. Additional studies are required to assess the differential effect of SCS doses and treatment duration to prevent relapse in children following discharge for acute asthma.
