Clinical remission attainment, definitions, and correlates among patients with severe asthma treated with biologics: a systematic review and meta-analysis
Abstract
BACKGROUND
Clinical remission has emerged as an important treatment goal in severe asthma; however, studies have reported variable attainment due to differences in study populations, definitions, and methods. We aimed to perform a systematic review and meta-analysis of clinical remission attainment, definitions, and correlates among patients with severe asthma who have been treated with biologics.
METHODS
In this systematic review and meta-analysis, we searched Web of Science, Embase, and MEDLINE, using the keywords "asthma" and "remission", for studies published between database inception and June 13, 2024, that reported clinical remission among patients with severe asthma treated with biologics. Studies were eligible for inclusion in both the systematic review and meta-analysis if they were published in English language peer-reviewed journals and reported rates of clinical remission for patients treated with biologics for severe asthma. There were no limitations by study design. Two reviewers independently screened identified papers (AS and CR), with disagreements resolved through consensus or referral to a third reviewer (JB). Study-level data on study characteristics, clinical remission definitions, clinical remission attainment, and the potential correlates of clinical remission were extracted independently by two reviewers (AS and CR) using Covidence. We defined a three-component definition of clinical remission, which included use of maintenance oral corticosteroids,…
How strong is the evidence?
Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid.
