Early Biologic Initiation in Inflammatory Bowel Disease Reduces Hospitalization and Surgical Risk: A Meta-Analysis of Real-World Evidence

Key Points

This research evaluates the impact of early biologic therapy initiation on clinical outcomes in inflammatory bowel disease.
Conducted a meta-analysis following PRISMA guidelines.
Searched multiple databases for studies over the past 25 years.
Included four studies comparing early versus delayed biologic therapy in adults with IBD.
Calculated risk ratios and confidence intervals using a random-effects model.
Early therapy reduced hospitalization risk by 37%.
Corticosteroid dependence decreased by 44%.
Surgical risks were halved with early therapy.
Early therapy modestly favored clinical remission but was not statistically significant.
Adverse events were comparable between early and late treatment groups.

Abstract

Abstract INTRODUCTION Despite advances in biologic therapies for IBD, the optimal timing for initiating treatment remains debated. Traditional step-up approaches may delay effective disease control. This meta-analysis evaluates whether earlier biologic use alters real-world outcomes in IBD, including remission, hospitalizations, corticosteroid dependence, and surgical risk. This study aimed to determine the comparative effectiveness of early versus late biologic therapy initiation in IBD using real-world clinical endpoints. METHODS Following PRISMA guidelines, we searched PubMed, Cochrane Library, ClinicalTrials.gov, PLOS ONE, and Google Scholar for studies from the past 25 years. Included studies compared early versus delayed biologic therapy in adults with Crohn’s disease or ulcerative colitis. Four eligible studies (n = 2,168) were included. Risk ratios (RR) and 95% confidence intervals (CI) were calculated using a random-effects model. Heterogeneity was assessed using the I2 statistic. RESULTS • Hospitalization: Early therapy reduced risk by 37% (RR 0.63; 95% CI: 0.49–0.81; I2 = 21%). • Corticosteroid Use: 44% reduction in dependence (RR 0.56; 95% CI: 0.41–0.75; I2 = 18%). • IBD-related Surgery: Risk halved (RR 0.51; 95% CI: 0.35–0.75; I2 = 0%). • Clinical Remission: Modestly favored early therapy (RR 1.24; 95% CI: 0.92–1.67; I2 = 27%) without reaching statistical significance. • Adverse Events: Comparable between early and late groups (RR 1.08; 95% CI: 0.88–1.33). CONCLUSION Early biologic initiation in IBD significantly reduces hospitalization, steroid use, and surgery without increasing adverse events. These findings advocate for a proactive treatment paradigm, particularly in patients with moderate-to-severe disease phenotypes. Future prospective studies should confirm whether early initiation translates to sustained remission and improved quality of life.
