[The effect of trandolapril, in monotherapy and associated with verapamil, on arterial pressure, albuminuria, and metabolic control in hypertensive patients with type 2 diabetes and albuminuria].
The aim of this study was to analyse the effect of the ACE-1, Trandolapril, alone or with Verapamil on blood pressure, albuminuria and metabolic profile in type 2 diabetic patients with hypertension and albuminuria. It was an open multicenter, consecutive and prospective study conducted in 281 patients. There was a four-week wash-out period of antihypertensive drugs, after which we carried out a measurement over a 24-h period of the urinary excretion of albumina (UEA). Blood pressure was recorded after at least 5 minutes of rest in the sitting position at 1 to 3 minute intervals with a mercury sphygmomanometer in good condition. Average BP was obtained from three consecutive readings. Within treatment changes were analysed using descriptive statistics and t-tests on the change from baseline. Analysis of variance, chi-square and Mc Nemar tests were also used. If after 8 weeks of treatment with Trandolapril 2 mg o.q.d. the patients were non-responders (mean blood pressure reduction of 5 mmHg or less) or their blood pressure remained uncontrolled (blood pressure > or = 140/90 mmHg), Verapamil 180 mg o.q.d. was added. Two hundred and thirty patients completed the 12 weeks study. Population included 157 (55.9%) males with an average of 61.7 +/- 9.2 years. Baseline measurements were systolic 165.4 +/- 14.6 and diastolic 94.8 +/- 8.5 mmHg blood pressures, fasting glucose 162.7 +/- 43.9 mg/dL, glycosylated hemoglobin (HbAlc) 6.8 +/- 1.2%, and albuminuria 520.9 +/- 602 mg/day. UEA fell significantly (p < 0.001) after treatment to 177.9 +/- 24.3 mg/day (CI 95%, 129.9 to 225.8). The percent reduction reached 29.6%. Albuminuria was lower than 30 mg/day in 47 patients. Blood pressure was completely controlled in 125 (54%) patients. Glucemia fell significantly (p < 0.001) to 153.2 +/- 42.7 mg/dL, and the HbAlc to 6.5 +/- 1.3% (p = 0.012). In summary, in those diabetic type 2 patients with arterial hypertension and proteinuria, Trandolapril alone or associated with Verapamil significant lowered albuminuria and blood pressure facilitated the control or their metabolic profile.
