Objectives

Narrative objectives1

To clarify the follow hypothesis.: Administration of an Olmesartan, which is an angiotensin II receptor blocker, reduces urinary angiotensinogen excretion, and suppresses oxidative stress and the inflammations with suppressing urinary albumin excretion.

Interventions/Control_1

This Study is a prospective randomized control trial. The entry period of this study is one year. Subjects are hypertensive diabetic nephropathy, who has not been taken RAS inhibitors. The patients are randomly assigned to two groups, a Olmesartan group (20mg/day or 40 mg/day) and Nifedipine CR group (20 mg/day or 40 mg/day). Both drugs can be properly increased to 40 mg/day, when the anti-hypertensive effect is insufficient.

Interventions/Control_2

The subjects were given Olmesartan or Nifedipine CR, and the following parameters were measured before administration and 16 weeks later: blood pressure, body weight, hemoglobin A1c, serum creatinine, urinary angiotensinogen, oxidative stress markers such as 8-epi-prostaglandinF2alpha and 8-hydroxydeoxyguanosine, inflammatory makers such as monocyte chemoattractant protein-1, interleukin-6, and albumin-to-creatinine ratio (ACR).

Key inclusion criteria

The subjects enrolled in the present study are hypertensive type 2 diabetic outpatients with nephropathy, who visit our hospitals and fulfilled the following criteria: 1) mild or moderate hypertension (blood pressure 130-200/90-110 mmHg) 2) mild or moderate hyperglycemia (HbA1c < 8%) 3) an urinary albumin excretion higher than 30 mg/g creatinine.

Key exclusion criteria
