Comparative effectiveness of sitagliptin and vildagliptin in the management of patients with type 2 diabetes mellitus undergoing haemodialysis: an Indian rural tertiary care centre experience

Suthakaran C., Bhaskaran S.


Background: The prevalence of chronic kidney disease is increasing with diabetic nephropathy as the common underlying cause. Although numerous drugs are being used to improve glycaemic control, evidence in patients with diabetic nephropathy is sparse. The aim of the present was to evaluate the effectiveness of sitagliptin or vildagliptin addition on glycaemic control in patients with T2DM undergoing haemodialysis as part of their routine care in a rural tertiary care setting.

Methods: Type 2 diabetic patients on maintenance haemodialysis as part of routine care and whose glycaemia was not controlled adequately and prescribed one of the oral gliptins once daily in addition to existing therapy for a period of 24 weeks were included in the present study. Effectiveness was assessed in terms of glycaemic control as measured by the change over time in glycated haemoglobin. Data analysis included glycated haemoglobin, body weight, serum creatinine, urine albumin creatinine ratio and the occurrence of hypoglycaemia.

Results: Significant reduction in glycated haemoglobin values were noted after 24 weeks of therapy with gliptins similar to insulin glargine with a small weight loss. There was an insignificant decrease in the serum creatinine and urine albumin excretion levels after treatment with vildagliptin with Vildagliptin producing a slightly higher decrease but there was no correlation with changes in A1c levels. The overall incidence of adverse experiences was low and generally mild in both groups.

Conclusions: In a group of Asian Indian patients with diabetic nephropathy due to T2DM undergoing haemodialysis in whom glycaemia was not controlled adequately, addition of gliptins helped to achieve glycaemic control to a similar extent as insulin glargine but with a marginal weight advantage.
