title: [Effect of 5-month guanfacine treatment on the renin-angiotensin-aldosterone system and some metabolic factors in patients with diabetes mellitus type II and hypertension].
abstract: The group of the investigated included 25 individuals (11 F, 14 M), aged 55 +/- 1.5 years, with diabetes type II and hypertension. Known diabetes duration was 4.9 +/- 0.8 years and known hypertension duration--7.4 +/- 1.4 years. Two weeks after administering placebo in place of hypertension drugs applied so far, guanfacine was included as the only hypertensive drug. The dosage was increased from 0.5 mg up to 3 mg daily until a good control of blood pressure was achieved. The diabetic treatment, diet and the smoking habit were unchanged. The resting activity of the renin-angiotension-aldosterone system (RAA), cholesterol, triglycerides, HDL and LDL, serum glucose levels and HbA1c were assayed after a 5-month guanfacine period. After treatment a significant decrease in blood pressure both systolic and diastolic (p < 0.001), heart rate (p < 0.005) and plasma renin activity (p < 0.02) were observed. Preliminary measurements of RAA activity and its changes during treatment were not helpful in predicting guanfacine hypotensive effect. The level of lipids, lipoproteins, atherogenic factors, glucose and HbA1c did not change significantly during the study.
