Nakano S, Uchida K, Ishii T, Takeuchi M, Azukizawa S, Kigoshi T, Morimoto S. Association of a nocturnal rise in plasma alpha-atrial natriuretic peptide and reversed diurnal blood pressure rhythm in hospitalized normotensive subjects with non-insulin dependent diabetes mellitus. Eur J Endocrinol 1994;131:184–90. ISSN 0804–4643 Diurnal changes in plasma atrial natriuretic peptide (ANP), plasma renin activity (PRA) and plasma aldosterone as related to those in blood pressure (BP) were studied under hospital conditions in 18 diabetic subjects without proteinuria and 8 age-matched control subjects. Of 18 diabetic subjects, 10 had a normal diurnal BP rhythm with the peak value in the afternoon (group 1) and 8 had a reversed BP rhythm with the peak value during the night (group 2). Autonomic dysfunction estimated by measuring orthostatic BP and heart-rate changes and beat-to-beat heart-rate variations was more pronounced in group 2 than in group 1. Fasting plasma glucose and HbA1c were similarly high in both diabetic groups. Group 1 showed modestly elevated mean 24-h MBP and plasma ANP levels, modestly low mean 24-h PRA and plasma aldosterone levels, and a lack of diurnal ANP changes similar to that in controls. Group 2 showed markedly elevated mean 24-h BP and plasma ANP levels, markedly low mean 24-h PRA and plasma aldosterone levels, and nocturnal rises in plasma ANP and BP. PRA and plasma aldosterone exhibited circadian rhythms with their peak values found in the early morning in all three groups. The daytime/overnight excretion ratios of sodium and water were normal in group 1 and low in group 2. These results indicate that diurnal changes in plasma ANP, PRA and plasma aldosterone are altered in diabetic subjects with normal and reversed diurnal BP rhythms, predominantly in the latter.
