Insights
Olmesartan, a hypertension medication, can cause sprue-like enteropathy, a rare gastrointestinal condition. Discontinuing olmesartan resolved the patient's symptoms, highlighting the importance of medication review.
Area of Science:
- Gastroenterology
- Pharmacology
- Internal Medicine
Background:
- Ischemic heart disease and stroke are leading global causes of mortality.
- Hypertension is a significant risk factor for cardiovascular diseases.
- Olmesartan, an angiotensin II receptor blocker (ARB), is prescribed for hypertension management.
Observation:
- A 72-year-old patient presented with chronic diarrhea, vomiting, and weight loss.
- Intestinal biopsy revealed villous atrophy, indicative of malabsorption.
- The patient was taking olmesartan for hypertension.
Findings:
- The patient's gastrointestinal symptoms resolved after olmesartan was discontinued.
- This suggests a causal link between olmesartan use and sprue-like enteropathy.
- Villous atrophy normalized, confirming the diagnosis.
Implications:
- This case underscores the importance of detailed medication histories in diagnosing unexplained gastrointestinal symptoms.
- Physicians should consider olmesartan-induced enteropathy in patients with similar presentations.
- Regular medication review is crucial for patient safety and effective treatment.
Abstract:
Ischemic heart disease and stroke are the leading causes of mortality worldwide according to the World Health Organization. Hypertension is a major factor in the development of these diseases. Olmesartan is an angiotensin II receptor blocker (ARB) indicated in the treatment of hypertension. There are several case reports describing sprue-like enteropathy caused by olmesartan. We report on a 72-year-old patient referred to our hospital for work-up of chronic diarrhoea, vomiting and weight-loss, and villous atrophy on intestinal biopsy. The patient's symptoms abated upon cessation of olmesartan. This case illustrates the need for a thorough medication history and regular review during work-up. We hope it will add to the current understanding of this rare phenomenon.
