Captopril Treatment in Bartter's Syndrome

Abstract

A 13-year-old girl presented with lassitude, polyuria and hypokalemia. Plasma renin concentration and urinary prostaglandin excretion were elevated, whereas plasma aldosterone concentration, urinary aldosterone excretion and blood pressure were normal. A diagnosis of Bartter's syndrome was made. The result of treatment with oral potassium was unsatisfactory. Treatment with acetylsalicylic acid had some effect, but an allergic reaction rendered withdrawal necessary. Treatment with the angiotensin converting enzyme inhibitor captopril and oral potassium led to clinical and biochemical improvement.
