Abstract
INTRODUCTION: Teneligliptin is a recently developed Dipeptidyl Peptidase 4 (DPP4) inhibitor. Teneligliptin is suitable for glycaemic control with renal impairment including end stage renal disease. AIM: To assess the efficacy and safety of teneligliptin in Asian Indian patients of Type 2 Diabetes Mellitus (T2DM) with early Diabetic Kidney Disease (DKD). MATERIALS AND METHODS: This was a single centre, retrospective analysis of patients with early DKD, who received teneligliptin 20 mg once daily for 24 weeks. Data related to glycaemic parameters, kidney function, lipid levels, retinopathy, neuropathy and safety variables available at 12 and 24 weeks were analysed. Descriptive statistical analysis was carried out. Statistical significance was assessed at a 5% level. RESULTS: Total 37 patients (21 males; 16 females) were analysed. Compared to baseline, significant reduction in Fasting Plasma Glucose (FPG) (mg/dl) (143.89±28.26 vs. 125.78±20.52, p=0.001); Postprandial Glucose (PPG) (mg/dl) (200.62±41.88 vs. 165.76±26.02, p=0.001); Glycated Haemoglobin (HbA1c) (%)(8.65±0.58 vs. 8.17±0.54, p=0.001) was noted at 12 weeks. This trend was further continued for 24 weeks with significant reduction in mean FPG, PPG and HbA1c to 113.73±16.82 mg/ dl (p=0.008); 142.95±20.76 mg/dl (p=0.001); and 7.65±0.45% (p=0.001) respectively. Significant improvement in serum creatinine (mg/dl) (2.45±0.27 vs. 2.26±0.23, p=0.001) and eGFR (CKD-EPI), (ml/min/1.73 m(2)) (53.35±4.24 vs. 55.08±4.19, p=0.001) was noted at 12 weeks and continued for 24 weeks with reduction in serum creatinine of 0.37±0.18 mg/ dl (p=0.001) and increase of eGFR of 4.60±1.59 ml/min/1.73 m(2) (p=0.001). At baseline, proteinuria was noted in all patients while at 24 weeks, 40.5% (p=0.001) patients did not report proteinuria. Significant improvements in lipid parameters with no deterioration in retinopathy and subjective improvement in peripheral neuropathy was also noted. No adverse events were noted. CONCLUSION: Teneligliptin reported significant and sustained improvement in glycaemic control in Asian Indian Patients of T2DM with early DKD and was well tolerated. Additionally, Teneligliptin reported significant improvement in renal function.
