ARTICLE HIGHLIGHTS
Research background

Diabetes is believed to accelerate the process of atherosclerosis in patients, and abnormal endothelial function is an important factor leading to diabetic kidney damage.

Research motivation

The dipeptidyl peptidase 4 inhibitor ligliptin can effectively reduce blood sugar. It has certain effects on the cardiovascular system and does not increase adverse reactions.

Research objectives

This study aimed to investigate the efficacy of ligliptin in the treatment of type 2 diabetes mellitus (T2DM) with early renal injury and its effect on serum endogenous hydrogen sulfide, endothelial cell particles, and endothelial function.

Research methods

Totally 110 patients with T2DM and early kidney injury were divided into either an observation group to receive ligliptin treatment or a control group to receive gliquidone therapy. Blood glucose and renal function were compared between before and after treatment and between the two groups.

Research results

The differences in fasting blood glucose, 2 h blood glucose, and glycated hemoglobin were not statistically significant between the two groups after treatment. The urinary albumin excretion rate after treatment in the ligliptin group was significantly lower than that of the gliquidone group. Serum endogeneous H2S and endothelial cell microparticles of the ligliptin treatment group were significantly lower than those of the gliquidone treatment group; endothelin-dependent diastolic function and nitric oxide after treatment in the ligliptin group were significantly higher than those of the gliquidone treatment group.

Research conclusions

Ligliptin treatment of T2DM with early renal injury has the same glucose-lowering effect as gliquidone treatment. Ligliptim treatment has a better effect and can significantly improve the renal function and vascular endothelial function of patients, and reduce serum endogenous hydrogen sulfide and endothelial cell particle levels.

Research perspectives

The follow-up time in this study was short, the number of patients enrolled was small, and there may be measurement errors that have affected the accuracy of the results. Therefore, it is necessary to expand the sample size and conduct long-term follow-up studies to confirm our findings.
