Abstract

While metabolic acidosis is one of the most common complications in patients with chronic kidney disease (CKD), there are several uncommon etiologies that are challenging to diagnose. Here, we describe a patient on peritoneal dialysis who developed high anion gap metabolic acidosis secondary to acquired 5-oxoprolinemia from acetaminophen use. While CKD is a known risk factor for developing this potentially serious complication, this case further highlights how 5-oxoproline accumulation can occur, even with therapeutic dosing of acetaminophen.
