Sevelamer-Induced Gastrointestinal Disease in 12 Patients with End-Stage Renal Disease: A Case Series.

Abstract

Isolated case reports and case series have linked the use of sevelamer to severe gastrointestinal (GI) inflammation and perforation among patients with end-stage renal disease. In this study, we identified 12 cases of biopsy-proven sevelamer-induced gastrointestinal disease from a large urban community hospital over the course of 5 years. We described baseline characteristics, sites and types of injury, histological findings, timing and dosing of sevelamer initiation compared with symptom onset, and in a smaller subset, endoscopic resolution post drug cessation. We also reviewed preexisting conditions to identify trends in populations at risk. Several of the patients reviewed had preexisting conditions of decreased motility and/or impaired mucosal integrity. The presentation of disease was broad and included both upper-GI and lower-GI pathologies and in varying severity. There is a broad phenotypic range of sevelamer-induced gastrointestinal disease. As this becomes a more frequently recognized pathology, clinicians should be aware of how it may present and which populations may be more susceptible.
