ABSTRACT: The aim of his study was to compare the efficacy of pioglitazone with metformin on the reduction of albuminuria in type 2 diabetic patients with hypertension and microalbuminuria treated with renin-angiotensin system inhibitors (RAS-Is).
The open-label, randomized trial was performed in type 2 diabetic patients with hypertension and microalbuminuria. On the basis of the treatment with RAS-Is, 68 patients with microalbuminuria received either pioglitazone (15-30 mg/day; n = 32) or metformin (500-750 mg/day; n = 31) for 52 weeks. Urinary albumin-to-creatinine ratio (UACR) was measured every 12 weeks.
After 52 weeks of treatment, the changes in the log-UACR from baseline were -8.3% in the pioglitazone group and +4.2% in the metformin group (p = 0.01), with similar glycemic and blood pressure changes.
The combination of pioglitazone and RAS-Is showed therapeutic benefit in the reduction of urinary albumin excretion for type 2 diabetic patients with hypertension and microalbuminuria.
