Influence of proton pump inhibitor use on clinical outcomes of patients with inflammatory bowel disease
Abstract
Objective: Proton pump inhibitor (PPI) use has been associated with reduced diversity of the gut microbiome and may lead to worse clinical outcomes in inflammatory bowel disease (IBD). We aimed to evaluate whether PPI use affects clinical outcomes in a real-world setting.
Design: Healthcare claims data of adult IBD patients were obtained from the IBM MarketScan Database. Multivariable analysis and propensity score-matched analysis were performed to assess associations between PPI use and new biologic start, and IBD-related hospitalizations and surgeries.
Results: A total of 46,234 IBD patients were identified (6,488 (14%) and 39,746 (86%) patients with and without PPI, respectively). Patients on PPI were more likely to be older, female, and smokers and less likely to be on immunomodulators. Multivariable analyses demonstrated that PPI use was associated with new biologic start (odds ratio (OR) 1.11, 95% confidence interval (CI) 1.04-1.18), and IBD-related admissions (OR 1.95, 95% CI 1.74-2.19) and surgeries (OR 1.46, 95% CI 1.26-1.71). Following propensity score matching, patients on PPI remained more likely to start a new biologic (23% vs 21%, p = 0.011), and have IBD-related admissions (8% vs 4%, p p p p < 0.001).
Conclusion: PPI use was associated with worse clinical outcomes in patients with IBD in the real-world setting. Further studies are warranted to validate these findings, but caution may be needed when prescribing a PPI to IBD patients.Study highlights WHAT IS…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 46,234 participants or records.
