Study summary

Patients newly diagnosed with T2D will be recruited and will receive sitagliptin treatment for 3 months. The gut microbiome of the participants before and after the treatment and the effectiveness of sitagliptin treatment on type 2 diabetes will be evaluated.

Read the detailed description

The dipeptidyl peptidase-4 inhibitor sitagliptin is a classic anti-diabetic drug(1) and is widely applied to both scientific research and clinical trial(2-6). This clinical trial aims to study the effectiveness of sitagliptin treatment in T2D patients and related change of gut microbiome. 50 Patients newly diagnosed with T2D will be recruited. With patient's informed consent, patient-related vital signs (such as age, height, weight, body mass index), laboratory indicators (including glycated hemoglobin, glycated albumin, low-density lipoprotein, total cholesterol, triglycerides), fasting blood glucose, insulin levels and Insulin resistance index (HOMA-IR)(7) will be recorded and analyzed. The feces of the patients will be collected to analyze the gut microbiome. All of the patients will receive the sitagliptin treatment for 3 months. The gut microbiome of the patients and the effectiveness of sitagliptin treatment on diabetes will be evaluated at indicated times during follow-up.
