Introduction: Diagnosis and initial management of diabetes mellitus (DM) in the young are clinical dilemma. Gliptins may be a safer and more effective option than sulfonylureas. Few Indian studies have addressed this issue of clinical relevance. Aim: To compare the use of sitagliptin and glimepiride as early add-on drugs along with metformin in young patients with DM to achieve optimum glycemic targets. Methods: This was a prospective, open-label, cohort study set in a tertiary care hospital in North India. Newly diagnosed patients of DM ≤35 year of age were initially treated to pre-defined glycemic goals (Fasting plasma glucose (FPG) 70-130, post prandial glucose (PPG) < 180 mg/dl) with insulin and metformin 1 g for 8 weeks. Insulin was discontinued and metformin increased to 2 g daily for next 4 weeks. Thereafter, glimepiride 1 mg or sitagliptin 100 mg was randomly added to those who were not maintaining the set glucose targets. Dose of glimepiride was uptitrated every 4 weeks upto a maximum of 4 mg. Three groups (Gp A: Metfromin 2 g/d, Gp B: Metformin 2 g + Glimepiride 1-4 mg/d, and Gp C: Metformin 2 g + sitagliptin 100 mg/d) were followed up over next 24 weeks. They were compared for glycemic control and weight change. Those failing therapy on these drugs (FPG > 180, PPG > 250 mg/dl with/without catabolic symptoms/ketosis) were withdrawn. Results: Sitagliptin with metfromin and metfromin alone group fared better than the glimepiride group for glycemic control, lesser treatment failures, and less weight gain. Conclusion : In this limited study, we found that sitagliptin is a safer and more effective option in young, newly diagnosed patients with DM. Findings of this study are relevant for clinical practice in Indian setting.
