PROSPECTS OF NEPHROPROTECTION AGAINST TYPE 2 DIABETES USING THE DPP-4 INHIBITOR VILDAGLIPTIN

Abstract

Diabetic nephropathy (DN) is a serious complication of diabetes mellitus (DM), which increases morbidity and mortality. Accumulated evidence, mostly experimental ones that DPP-4 inhibitors have non-glycemic tissue effects including renal protection. Clinical data confirming these effects are insufficient. This makes it relevant to study the influence of iDPP-4 on the renal function in patients with Type 2 diabetes.To study the effects of iDPP vildagliptin on glycemic, metabolic and renal parameters in patients with type 2 diabetes with CKD 1–2 receiving insulin therapy 44 patients were randomized to continue therapy with insulin or insulin + vildagliptin at a dose of 50 mg/day, with the evaluation of results in 6 months.In group of vildagliptin therapy a significant decrease of HbA1c, postprandial glycemia, diastolic blood pressure, HOMA-IR, insulin demand and a reduction in the frequency of hypoglycemia occurred. The positive dynamics of indicators of glomerular functions of the kidney were noted in this group - a significant reduction in albuminuria and a significant increase in eGFR by cystatin C and decreased urinary excretion of type IV collagen. The findings suggest the positive effect of vildagliptin on metabolic status and indicators of glycaemia and hemodynamics as earlier confirmed in clinical studies and the ability of vildagliptin independent from glycemic effects to slow the development of glomerular dysfunction in patients with type 2 diabetes and the initial manifestations of DN.
