    Abstract:
    INTRODUCTION: Adiponectin is secreted from adipose tissue and exhibits a protective effect against cardiovascular disease; plasma adiponectin concentrations are decreased in type 2 diabetic and in hypertensive patients. OBJECTIVE: The aim of this study was to compare the effect of trandolapril (T) and its fixed-dose combination with verapamil (FDTV) on adiponectin levels in hypertensive type 2 diabetic patients. METHODS: A total of 40 type 2 diabetic patients with never-treated hypertension were randomly assigned to two groups. One group received FDTV 180 mg + T 2 mg, once a day; the other group received T 2 mg once a day, administered for 3 months in both groups. Adiponectin was measured by enzyme-linked immunosorbent assay (ELISA) at the beginning and end of the study. Patients were evaluated monthly for blood pressure, fasting serum glucose and adverse events. Statistical analysis was performed with analysis of variance (ANOVA). RESULTS: All patients experienced a significant reduction of blood pressure. Both therapeutics regimens increased the levels of adiponectin, However, FDTV produces a higher increase in the levels of the hormone (8.15 ± 4.6 to 10.96 ± 5.6 µg/ml) when compared with the T treatment (7.64 ± 3.8 to 8.92 ± 4.4 µg/ml), p < 0.05. None of the patients suffered adverse events. CONCLUSION: Our results show that the addition of FDTV to T produced a greater increase on adiponectin levels than trandolapril alone.
