Objective: To determine the effect of glucagon-like peptide-1 receptor agonist (GLP-1RA) on cases with type 2 diabetes mellitus (T2DM) in terms of insulin dosage and blood glucose (BG) control.
Methods: A total of 180 patients with T2DM admitted to our hospital between March 2016 and March 2019 were selected and assigned to a GLP-1RA group (GLP-1 group, n=100) and a control group (control group, n=80). Patients in the GLP-1 group were treated with GLP-1RA combined with insulin, while those in the other group were treated with insulin alone. The following items of each patient were determined: Body weight, body mass index (BMI), waist circumference, blood pressure (BP), BG-related indexes, insulin dosage, insulin resistance index, cardiovascular function, serum lipid-related indexes, adverse reactions, total effective rate, and treatment satisfaction.
Results: Compared with the control group, the GLP-1 group showed a decrease in weight, BMI, waist circumference, BP, BG-related indexes, and insulin resistance index, consumed less insulin dosage, and also showed a decline in cardiovascular function, serum lipid-related indexes (total cholesterol (TC), triacylglycerol (TG), and low density lipoprotein cholesterol (LDL-C)), an increase in high density lipoprotein cholesterol (HDL-C), less adverse reactions, and higher total effective rate and treatment satisfaction.
Conclusion: GLP-1RA contributes to better BG control of patients with T2DM, and it reduces the insulin dosage required during operation for its stimulation to the production of insulin.
