    Abstract:
    Hypertension is more frequently found in patients with diabetes mellitus than in subjects with normal glucose tolerance. On the other hand, concomitant hypertension accelerates the progression of diabetic nephropathy. To examine whether human atrial natriuretic peptide (human ANF-[99-126], hANP) is involved into the pathogenesis of hypertension and nephropathy of diabetic patients and to find out whether the detection of increased hANP levels can serve as an early marker, helping to identify diabetic patients at increased risk of developing these diabetes complications, we studied 107 randomly selected patients with Type 1 or Type 2 diabetes mellitus (53 women, 54 men). There were no differences between patients with normal hANP levels and patients with hANP levels above normal range regarding age, diabetes duration, metabolic control, kidney function (creatinine clearance and proteinuria), electrolytes, and in plasma renin activity, aldosterone, epinephrine and norepinephrine levels in plasma. However, higher blood pressure was measured and antihypertensive therapy was found more frequently in patients with increased hANP levels (p less than 0.05). This was confirmed by analyzing the subgroup of patients with normal blood pressure without antihypertensive therapy: Again, diastolic blood pressure was found to be higher (p less than 0.05) in patients with elevated hANP than in patients with normal hANP levels. In this subgroup, increased creatinine clearance tended to be found more frequently among patients with increased hANP levels.(ABSTRACT TRUNCATED AT 250 WORDS)
