Objectives

Narrative objectives1

To clarify the renoprotective effects of pioglitazone in diabetic nephropathy.The purpose of this study was to investigate whether pioglitazone inhibits imflammation and oxidative stresses more potently than other hypoglycemic agents under blockade of RAS and exerts renoprotection in type 2 diabetic nephropathy

Interventions/Control_1

This study is a prospective randomized control trial. The entry period of this study is one year. Subjects were type 2 diabetics with nephropathy, taking RAS inhibitors. The patients were randomly assigned to two groups, a pioglitazone group (7.5 mg/day or 15 mg/day) and other hypoglycemic agents group. Pioglitazone can be properly increased to 30mg/day when the anti-hyperglycemic effect is insufficient.

Interventions/Control_2

Blood pressure, body weight, hemoglobin A1c (HbA1c), serum creatine, serum lipids, the plasma and urinary levels of monocyte chemoattractant protein (MCP)-1, interleukin-6 (IL-6) and, urinary albumin excretion (albumin to creatinine ratio: ACR) and urinary excretions of 8-hydroxydeoxyguanosine (8-OHdG) were determined before (baseline levels) and after the treatment for 6 months , 12 months and 24 months.. We collected fasting blood and first urine samples in early morning.

Key inclusion criteria

The subjects enrolled in the present study were type 2 diabetic out-patients with nephropathy, who visit our hospitals and fulfilled the following criteria:1) Mild or moderate hyperglycemia, defined as the HbA1c of 6.0-7.9 %. 2) Use of RAS inhibitors, such as an angiotensin-converting enzyme inhibitor (ACEI) or an angiotensin II type-1 receptor blocker (ARB), for at least six months. 3) A urinary albumin-to-creatinine ratio (ACR) higher than 30 (mg/mgCr) (stage of diabetic nephropathy: stage II and higher).4) Not severe hypertension (blood pressure < 160/110 mmHg)

Key exclusion criteria

1) A serum creatinine (Cr) level is more than 2.5 (mg/dl) and existence of hematuria.2) Patient who has received continuous dialysis.3) Severe diabetic complications such as retinal hemorrhage, neuropathy, and so on.4) Existence of severe hepatic damages, and cerebrovascular disorders including heart failure.5) Severe hypertension (BP>160/110 mmHg)6) Patients who judged that physician in charge is improper.
