Renoprotective Effects of Teneligliptin: An Observational Study

Abstract

Aim: The aim of this study was to validate the potential of teneligliptin in managing type 2 diabetes mellitus (T2DM) with renal impairment and to evaluate its effect on renal parameters in Indian subjects. Patients and Methods: The prospective observational study included 86 subjects aged >40 years with suboptimal control of T2DM (HbA1c >7.5). The demographic details of the selected subjects were recorded. The patients were continued on existing oral hypoglycemic agents (OHAs) and antihypertensives. The following clinical and anthropometric parameters were measured at baseline, 4 months, 8 months, and 12 months during the treatment using 20 mg of teneligliptin per day: HbA1c, eGFRs, UACR, FBG, and PPBG levels. Comparisons of anthropometric and laboratory parameters were carried out using analysis of variance (ANOVA) and t test for normal data, Kruskal-Wallis for nonnormal data, and chi-square test for counts data. Results: The mean age of the subjects was 54.28 ± 6.8 years and the male-To-female ratio noted was 1:0.65. The mean values of FBG (mg/dL ± SD) at 4, 8, and 12 months were found to be statistically significant (P < 0.001, 117.12 ± 30.51, 109.69 ± 43.66, and 113.16 ± 56.93, respectively).T test carried out for PPBG indicated that the levels at respective intervals were significantly reduced as opposed to baseline (P < 0.05). The difference in HbA1c (%) across baseline, 4, 8, and 12 months was found to be statistically significant (P < 0.001) and the mean levels noted were 8.09 ± 2.26, 7.57 ± 1.84, 6.95 ± 1.80, and 6.46 ± 1.81, respectively. The difference in UACR across different intervals was found to be statistically significant (P < 0.001) and the corresponding mean UACRs (mg/g ± SD) noted were 417.21 ± 182.87, 291.82 ± 98.30, 296.84 ± 109.48 and 284.18 ± 103.26. Conclusion: Teneligliptin monotherapy is well tolerated with a persistent reduction in HbA1C and significant improvement in renal function.
