Abstract
INTRODUCTION Olmesartan‐related sprue‐like enteropathy is a malabsorption syndrome characterized by chronic diarrhea and weight loss that develops after olmesartan initiation. The symptom onset often occurs from several months to years [...]
: Herein, we describe a case of olmesartan‐related sprue‐like enteropathy in which improvement in villous atrophy was confirmed by small‐bowel capsule endoscopy (CE). We successfully treated a 66‐year‐old man with a chief complaint of loose diarrhea. The patient had persistent watery diarrhea 10 times a day and experienced a weight loss of 9 kg in 3 months. An abdominal computed tomography scan showed fluid retention in the small intestine. Blood test results revealed no inflammatory reaction. Esophagogastroduodenoscopy detected villous atrophy in the stomach and duodenum. Moreover, small‐bowel CE showed villous atrophy in about two‐thirds of the small intestine. Based on other examinations, hyperthyroidism, intestinal tuberculosis, intestinal amyloidosis, and intestinal malignant lymphoma were ruled out. Therefore, the patient was suspected of having an olmesartan‐related sprue‐like disease. Early after discontinuation of medication, diarrhea symptoms improved, and a repeat CE indicated improvements in small intestinal villous atrophy. Since the patient had been administered olmesartan for a long time and CE showed villous atrophy throughout the small bowel, we suspected him of having the olmesartan‐associated sprue‐like disease. The findings of gastric mucosa atrophy on esophagogastroduodenoscopy may lead to an early diagnosis of this disease. Olmesartan‐related sprue‐like enteropathy should be considered as a differential diagnosis in patients with chronic severe watery diarrhea.
