Olmesartan-associated enteropathy. A rare but easily treatable entity

A 76-year old woman, with a history of atrial fibrillation, hypertension and hypothyroidism, was referred to our clinic due to a 6-month history of severe diarrhea (7-8 watery stools per day and weight loss of about 30kg). She also complained of intense pruritus in the past 3 months. She reported an unsuccessful trial of empirical treatment for scabies and inadequate response to oral antihistamines. At presentation, a widespread maculopapular rash with scabs was noted. Previous evaluation included a colonoscopy and esopha- gogastroduodenoscopy (without biopsies), an abdominal CT and MRI and an endoscopic ultrasound without significant findings.
