Abstract
Olmesartan-associated enteropathy is a rare cause of severe enteropathy that should be considered in the differential diagnosis of patients with unexplained chronic diarrhoea. It may be difficult to recognise because of its clinical and histologic similarities to other clinical entities. The authors present the case of a 72-year-old woman with a 6-month clinical history of non-bloody diarrhoea and weight loss. Discontinuation of olmesartan resulted in clinical and histologic recovery, and therefore, physicians need to be aware of olmesartan-associated enteropathy in order to avoid unnecessary testing. Although rare, it is considered an emerging and underdiagnosed enteropathy.LEARNING POINTSOlmesartan-associated enteropathy is characterised by chronic diarrhoea (often severe) and weight loss that is unresponsive to a gluten-free diet.When a patient presents with unexplained chronic diarrhoea, a detailed medication review is needed. If duodenal biopsies reveal villous atrophy and coeliac disease is excluded, drug-induced enteropathy is likely.Clinical response and histologic improvement are expected after olmesartan is withdrawn.
