Primary Outcome Measures:
  • proteinuria [ Time Frame: 12 weeks ]

Secondary Outcome Measures:
  • efficacy: filtration fraction, renal nitric oxide bioavailability, insulin resistance, platelet function safety: tolerability, plasma glucose, body weight, edema [ Time Frame: 12 weeks ]

Study Start Date: July 2007
Study Completion Date: September 2009
Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: pioglitazone
    Pioglitazone 30 mg o.d. tablet for 12 weeks or placebo o.d. tablet for 12 weeks in random order. After 12 wk treatment there is a 4 wk washout out which is followed by switch of study medication in a cross over fashion and a further 12 wk treatment.
Detailed Description:

About 30 % of kidney transplant recipients will develop diabetes mellitus. This condition is a risk factor for graft dysfunction, graft loss and increased mortality of patients. Inflammatory reactions within the graft and proteinuria are considered as pathogenetic mechanisms.

Recent studies indicated that pioglitazone might have beneficial effects on the urinary protein excretion of type 2 diabetic patients with diabetic nephropathy and was able to reduce systemic inflammation.

This lead to the hypothesis that pioglitazone could improve proteinuria of kidney transplant patients with diabetes.

Comparison: Effects of pioglitazone vs. placebo on proteinuria and renal function of kidney transplant recipients in a cross over study.
