Sevelamer-Induced Gastrointestinal Injury Presenting as Gastroenteritis

Abstract

End-stage renal disease (ESRD) is a common disease encountered in clinical practice and is associated with increasing metabolic derangements through disease progression. Phosphate retention is one of the most common derangements and is associated with increased mortality. Hyperphosphatemia becomes increasingly prevalent as glomerular filtration rate decreases. Non-calcium phosphate-binding resins and dietary phosphate restriction are the mainstays for managing hyperphosphatemia in patients with ESRD. Sevelamer carbonate is the most frequently used non-calcium phosphate binder in the US due to ease of administration and an excellent safety profile. However, there is increasing recognition of gastrointestinal injury associated with medication use. Here we report a case of an 81-year-old male with biopsy-proven gastrointestinal mucosal injury secondary to sevelamer carbonate administration.
