ObjectivesThe purpose of this study was to assess the incidence of type 2 diabetes mellitus (T2DM) after 6 years in patients with IGT who received early probiotic intervention in the Probiotics Prevention Diabetes Program (PPDP) trial.Methods77 patients with IGT in the PPDP trial were randomized to either probiotic or placebo. After the completion of the trial, 39 non-T2DM patients were invited to follow up glucose metabolism after the next 4 years. The incidence of T2DM in each group was assessed using Kaplan-Meier analysis. The 16S rDNA sequencing technology was used to analyze gut microbiota’s structural composition and abundance changes between the groups.ResultsThe cumulative incidence of T2DM was 59.1% with probiotic treatment versus 54.5% with placebo within 6 years, there was no significant difference in the risk of developing T2DM between the two groups (P=0.674).ConclusionsSupplemental probiotic therapy does not reduce the risk of IGT conversion to T2DM.Clinical Trial Registrationhttps://www.chictr.org.cn/showproj.aspx?proj=5543, identifier ChiCTR-TRC-13004024.
