  • 1. To investigate atrial natriuretic factor (ANF) and its relationship to the renin system in diabetes, we measured plasma immunoreactive ANF and plasma renin activity (PRA) in 27 non-ketotic diabetic patients without evidence of cardiac or overt renal disease, and compared them with 26 age- and sex-matched normal subjects. 2. Diabetic patients were divided prospectively into poor (PGC, n = 14) or moderate (MGC, n = 13) glycaemic control depending on their concurrent plasma glycohaemoglobin (HbA1) levels (greater than 9% or less than 9%, respectively). Plasma ANF was elevated in PGC diabetic patients (15.7 +/- 1.8 fmol/ml, mean +/- SEM) compared with MGC diabetics (9.9 +/- 0.8 fmol/ml, P less than 0.001) and normal subjects (10.1 +/- 1.3 fmol/ml, P less than 0.05). 3. In contrast, PRA was lower in the PGC diabetic patients (1.3 +/- 0.3 pmol of angiotensin 1 h-1 ml-1) compared with the other groups (2.5 +/- 0.5 and 2.1 +/- 0.2 pmol of angiotensin I h-1 ml-1, P less than 0.05). Diabetic groups had proportionally more patients with high prorenin values (over 30 ng h-1 ml-1) than the normal group, but there was no difference between the diabetic groups. 4. Among the diabetic patients, ANF was directly related to HbA1 (r = 0.49, P less than 0.005) and urinary albumin excretion (r = 0.40, P less than 0.02), and was inversely related to PRA (r = 0.36, P less than 0.04) and plasma creatinine (r = -0.42, P less than 0.02).(ABSTRACT TRUNCATED AT 250 WORDS)
