• Blood pressure less than 130/80 mmHg after 16 and 20 weeks of treatment
• Change from baseline 48-hour ambulatory blood pressure, and blood pressure less than 130/80 mmHg after 16 and 20 weeks of treatment
• Blood pressure less than 130/80 mmHg at night, measured by 48-hour ambulatory blood pressure monitoring, after 16 and 20 weeks of treatment
• Change from baseline in size of left heart ventricle by electrocardiogram (ECG) after 20 weeks
• Change from baseline in kidney function after 16 and 20 weeks

Title: Antialbuminuric effect of valsartan, lisinopril and valsartan versus lisinopril in non-diabetic and diabetic renal disease: a randomized (3:3:1), open label, parallel group, 20 weeks follow-up.

Objective: To evaluate the antialbuminuric effect of high doses of valsartan vs lisinopril vs combo treatment in non-diabetic and diabetic patients.

Hypothesis: Combo treatment reduces microalbuminuria and the albumin/creatinine ratio more than monotherapies..

Design: Multicentric, randomized, open label, parallel group, active controlled.

Dose / regimen: Valsartan 320 vs Lisinopril 40 vs Valsartan/lisinopril 160/20

Primary Endpoint: Antialbuminuric effect of valsartan 320 mg, lisinopril and valsartan versus lisinopril 40 mg in non-diabetic and diabetic renal disease following 5 months of follow-up. Description % of change in albuminuria from baseline at 20 weeks.

Secondary Endpoint : To investigate the effect of 5 months treatment with valsartan,lisinopril and valsartan versus lisinopril in GFR (Cl creatinine), also to investigate the effect of 5 months treatment with valsartan, lisinopril and valsartan plus lisinopril on blood pressure and the effect on left ventricular mass index using electrocardiogram and Cornell-Sokolow method.
