Abstract

An 87-year-old man with history of hypertension, diabetes mellitus, atrial fibrillation, recurrent kidney stones, and prostate cancer was referred for recurrent “Clostridium difficile”-associated diarrhea. The patient’s only gastrointestinal past medical history included an asymptomatic 5-8 mm tubular adenoma and diverticulosis noted on colonoscopy several years prior to presentation. He presented with a urinary tract infection for which he received a 2-week course of ciprofloxacin. On day 10 of ciprofloxacin, he was brought to the emergency room in extremis with diarrhea, vomiting, fever, dehydration, and leukocytosis.
