Brief Summary

The Akkermania muciniphila may play an important role in the occurrence and development of Prediabetes. The purpose of this study was to evaluate the safety and efficacy of AKK in the treatment of Prediabetes among obese patients. In this study, a single center, randomized, double-blind, placebo-controlled design is adopted. 90 obese subjects with Prediabetes are included in this study, and are allocated to AKK group, BBR group, and placebo group at a ratio of 1:1:1. The study treatment lasts for 12 weeks. The changes of body fat, glucose metabolism, lipid metabolism indicators compared with the baseline at the end of the treatment will be analyzed. In addition, glucagon like peptide-1 (GLP-1) and inflammatory markers (hsCRP、TNF-α、IL-6、IL-8、IL-1β) in blood will be analyzed before and after treatment. The changes in fecal flora structure and the AKK bacteria also will be analyzed.
