简要总结
Investigation of the efficacy of fecal microbiota transplantation added to calorie-restricted diet and semaglutide versus calorie-restricted diet and semaglutide alone for weight loss and metabolic improvement in patients with moderate to severe obesity and type 2 diabetes mellitus.
详细描述
This study is designed as a single-center, randomized, open-label, parallel-controlled trial. A total of 20 patients with moderate to severe obesity and T2DM (BMI 30-40 kg/m²) whose T2DM duration is less than one year will be enrolled, and randomly assigned to either the intervention group (FMT + ccalorie-restricted diet + semaglutide) or the control group (calorie-restricted diet + semaglutide). The intervention period will be 24 weeks. The primary endpoint is the percentage change in body weight from baseline to post-intervention. Secondary endpoints include the proportion of patients achieving a >5% weight loss, as well as metabolic parameters such as fasting blood glucose, lipid profile, glycated hemoglobin, visceral fat parameters, and gut microbiota diversity (Shannon/Simpson index).
