title: Plasma renin activity and blood volume in uncontrolled diabetes. Ketoacidosis, a state of secondary aldosteronism.
abstract: The renin-angiotensin-aldosterone system was evaluated in two types of uncontrolled diabetes: a) diabetic ketoacidosis, and b) nonketotic hyperglycemia. In thirteen patients with ketoacidosis, mean plasma renin activity (PRA) was 58 plus or minus 12 (S.E.M.) ng. per milliliter per hour and in four patients, plasma aldosterone was 82 plus or minus 17 ng. per 100 ml. Corresponding values for upright salt-depleted subjects were 13 plus or minus 2 and 62 plus or minus 8. In eleven diabetics with nonketotic hyperglycemia (mean glucose 318 plus or minus 19 mg. per cent), mean blood volume was 4,660 ml. and PRA 2.1 plus or minus .7. After control of the diabetes (mean glucose 129 plus or minus 13) blood volume was 4,553 ml. and PRA 3.3 plus or minus 1 (NS). The results suggest that: 1) diabetic ketoacidosis is a state of severe secondary aldosteronism, 2) no significant change in blood volume or PRA occurs during short periods of hyperglycemia, and 3) insulin is not necessary for renin release.
