The effects of GLP-1 analogues on pre-diabetes of the children.

The aim of the study was to evaluate the clinical efficacy of glucagon-like peptide-1 (GLP-1) analogues in children of pre-diabetes to delay or reverse the development of pre-diabetes into the state of diabetes by early intervention. Prospective and randomized controlled clinical trials were performed in 42 cases of newly diagnosed pre-diabetes in children. The sample size was randomly divided into the two groups. The first group included 21 subjects comprising the lifestyle intervention group, i.e., control group, and the second group included 21 subjects comprising the lifestyle intervention+GLP-1 analogues liraglutide group, i.e., observation group. Interventions carried out lasted 3 months. A review of intervention was carried out at 1 month and after 3 months. Medical examinations were carried out at the the time following diagnosis with pre-diabetes and after the intervention of 3 months. The medical test examinations included the fasting blood glucose (FPG), 2-hour postprandial blood glucose (2hPG), detection of glycated hemoglobin A1c (HbA1C), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), body mass index (BMI), insulin resistance (IR) and the islet cell functions. After 1 month of intervention, the observation group exhibited a better control on FPG and 2hPG compared with the control group (P<0.05). After 3 months of the intervention, FPG and 2hPG levels of the observation group were significantly lower than those of the control group (P<0.01). The levels of HbA1C, TC, TG, LDL-C, HDL-C, and BMI of the observation group were statistically better controlled, when compared with the control group after the intervention of 3 months. The IR index of the observation group was significantly decreased compared to that of the control group (P<0.05) and the islet function index of the β-cell of the observation group showed statistically higher values than that of the control group (P<0.05). In conclusion, GLP-1 analogues are a better regulator of blood sugar levels, effectively improve lipid profile, body mass, IR and islet β-cell function. Furthermore, GLP-1 analogues opens up a new way to intervene pre-diabetes in children.
