PG - 493-8 LID - 10.4158/EP11378.OR [doi] AB - OBJECTIVE: To observe the effects of pioglitazone hydrochloride on urinary sediment podocalyxin and monocyte chemoattractant protein-1 (MCP-1) excretion in patients with type 2 diabetes and to explore its possible renoprotective mechanisms. METHODS: Ninety-eight patients with uncontrolled type 2 diabetes, who were previously prescribed metformin, acarbose, or both, were randomly assigned to a DP group (add-on pioglitazone; n = 49) or a DS group (add-on sulfonylurea; n = 49). RESULTS: After 12 weeks of treatment, both add-on pioglitazone therapy (the DP group) and add-on sulfonylurea therapy (the DS group) demonstrated a similar improvement in fasting blood glucose and hemoglobin A1c, but systolic and diastolic blood pressure declined significantly in only the DP group. Moreover, the DP group showed significantly better efficacy in reducing urinary MCP-1 excretion in comparison with the DS group. Furthermore, both urinary albumin and urinary sediment podocalyxin excretion decreased significantly in the DP group but not in the DS group. The urinary sediment podocalyxin to creatinine ratio had a positive correlation with urinary albumin to creatinine ratio (r = 0.624; P<.01) and urinary MCP-1 to creatinine ratio (r = 0.346; P<.01). CONCLUSION: Pioglitazone treatment revealed a podocyte-protective capacity in patients with type 2 diabetes, and the underlying mechanisms may be partly attributed to its effective suppression of excessive local renal inflammation.
