Patients with inflammatory bowel disease (IBD) on infliximab have a higher incidence of hospitalization when there is concurrent proton pump inhibitor (PPI) therapy, according to research presented at the Advances in Inflammatory Bowel Diseases (AIBD) 2021 Annual Meeting, held from December 9 to 11, 2021, in Orlando, Florida and virtually.
Investigators performed a cohort study including 104 patients with IBD on infliximab therapy. They aimed to assess whether PPI therapy in this patient population was associated with lower rates of clinical remission and increased rates of hospitalization. Minimum follow-up was 54 weeks. The primary endpoints were deep remission at week 54 and need for hospitalization, treatment with corticosteroids, or abdominal surgery, following induction of infliximab.
In total, 53.8% of patients included in the analysis were women with a mean age of 38.2±13.1 years. The majority of patients (74%) had CD and 20.2% were undergoing PPI therapy.
After 54 weeks, patients receiving PPIs had significantly lower rates of remission compared with non-PPI patients (7.7% vs 28.3%; P =.034); however, the difference was minimized when additional confounders such as smoking habit, age, and sex were factored in (odds ratio [OR], 0.16; 95% CI, 0.02-1.63; P =.121). IBD-related hospitalization was 3-times higher in patients receiving PPIs, even after adjusting for confounders (OR, 3.22; 95% CI, 1.11-9.34; P =.04).
Researchers believe, “These findings emphasize the importance of restricting PPI treatment to those with a clear clinical indication, especially in this set of patients.”
