Interventions/Control_1
Patients of intervention group are treated with pioglitazone orally from the dose of 15mg/day, increasecd to the continuous dose of 15-45mg/day within one month, and continued for 3 years. The efficacy and side effects are evaluated.
Interventions/Control_2
Patients of control group are treated with pioglitazone dipyridamole orally from the dose of 150mg/day, increasecd to the continuous dose of 300mg/day within one month, and continued for 3 years. The efficacy and side effects are compared with intervention group.

Results
Short-term (6 months) treatment effects of the study were announced at the Japanese Society of Nephrology in June 2010 that, although there was no improvement in renal function in the pioglitazone group, there was a slight reduction in proteinuria. Therefore, this study was planned to investigate the long-term treatment effects, but at the same time there were reports of side effects caused by pioglitazone, and patient enrollment did not progress at all, so the study was discontinued.
