RT Journal Article SR Electronic T1 Reversible impairment of renal function associated with enalapril in a diabetic patient JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 1279 OP 1281 VO 159 IS 10 A1 M. M. Albareda A1 R. Corcoy YR 1998 UL http://www.cmaj.ca/content/159/10/1279.abstract AB Acute renal failure and hyperkalemia due to angiotensin-converting enzyme inhibitors have been described in diabetic patients with other predisposing conditions. The case reported here involves a patient with type 1 diabetes mellitus, microalbuminuria and normal renal function who was treated with enalapril. Two years after initiation of this therapy, at a time when glycemic control was poor, he presented with symptomatic hyperkalemia and impaired renal function accompanied by hyporeninemic hypoaldosteronism. This case illustrates that reversible impairment of renal function and hyperkalemia can present after 2 years of treatment with angiotensin-converting enzyme inhibitors in patients with precipitating factors.
