Abstract:
The absence of suitable intervention significantly increases the likelihood of type 2 diabetes mellitus (T2DM) development in people with prediabetes. Recent statistical findings indicate that the gut microbiome might influences the development of insulin resistance. The objective of our study was to assess the efficacy and safety of probiotic supplementation in individuals diagnosed with prediabetes. A thorough search was carried out on the Cochrane Library, Medline, Scopus, and ClinicalTrials.gov databases until September 12th, 2024, using a mix of pertinent keywords. This review incorporates randomized clinical trials (RCTs) concerning the effect of probiotics for prediabetes. We used random-effect models to examine the mean difference (MD). A total of eight RCTs were incorporated. The results of our meta-analysis indicated that probiotics supplementation was associated with higher reduction in hemoglobin A1c (HbA1c) (MD -0.07% (95% CI -0.11, -0.03), p = 0.0005, I2 = 0%) among individuals with prediabetes when compared to placebo. Other indicators such as total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), and body mass index (BMI) did not differ significantly between probiotics and placebo. No significant difference was observed in the occurrence of adverse events (AEs) between the two groups. This study indicates the efficacy and safety of probiotics supplementation to improve the glycemic parameters in patients with prediabetes.
