Abstract:Objective To explore the efficacy of repaglinide combined with glyburide in the treatment of gestational diabetes mellitus (GDM) and its effects on levels of fasting blood glucose (FBG), 2-hour postprandial glucose (2hPG) and serum neutrophil gelatinase-associated lipocalin (NGAL).Methods The 112 GDM patients admitted to our hospital from January 2020 to January 2023 were selected and divided into the control group (treatment with glyburide) and the observation group (treatment with repaglinide combined with glyburide) by the random number table method, with 56 cases in each group. Glucose metabolism indexes (FBG, 2hPG, HbA1c) and levels of NGAL, homocysteine (Hcy), cystatin C (CysC), irisin and galanin (GAL) before and after treatment were compared between the two groups, and maternal and infant outcomes were statistically analyzed.Results The differences of levels of FBG, 2 hPG, and HbA1c before and after treatment in the observation group were higher than those in the control group (P < 0.05). The differences of levels of serum GAL and irisin before and after treatment in the observation group were higher than those in the control group (P < 0.05). The differences of levels of NGAL, Hcy, and CysC before and after treatment in the observation group were higher than those in the control group (P < 0.05). There was no statistically significant difference in the overall incidence of prolonged labor, gestational hypertension, polyhydramnios, and premature rupture of membranes between the observation group and the control group (P > 0.05). The incidence of hypoglycemia in premature infants and newborns in the observation group was lower than that in the control group (P < 0.05).Conclusions Repaglinide combined with glyburide can effectively control blood glucose in patients with GDM, down-regulate serum levels of NGAL, Hcy, CysC and GAL, up-regulate the serum level of irisin, and improve the insulin resistance with a high safety profile, and should be recommended for clinical practice.
