GLUCOSE-INDUCED HYPERKALEMIA WITH NORMAL ALDOSTERONE LEVELS - STUDIES IN A PATIENT WITH DIABETES-MELLITUS

A diabetic patient exhibited glucose-induced hyperkalemia despite normal plasma and urinary aldosterone levels. The patient received no diuretics, was not acidotic, and had a creatinine clearance of 39 ml/min. Insulin or pharmacologic doses of desoxycorticosterone acetate eliminated the glucose-induced hyperkalemia. Normal aldosterone levels may be insufficient to protect certain diabetic patients from glucose-induced hyperkalemia.
