A systematic review and meta-analysis study was conducted to assess the effectiveness of probiotic/prebiotic/synbiotic supplementation on the effects of cardiovascular risk factors in patients with type 2 diabetes mellitus(T2DM)based on data from randomized controlled trials(RCTs).We searched electronic databases including PubMed,Cochrane Library,Embase,and Web of Science to identify clinical trials published up to 31 March 2023.Data was pooled using a random-effects model if significant heterogeneity(I2＞50％),otherwise use a fixed-effects model.Fifty-six trials that included 3 317 patients were enrolled for analysis.Meta-analysis reported that probiotic/prebiotic/synbiotic supplementation significantly reduced systolic blood pressure(SBP)(weighted mean difference(WMD):-3.57 mmHg,95％confidence interval(CI):-5.36,-1.78;P=0.000),diastolic blood pressure(DBP)(WMD:-2.05 mmHg,95％CI:-3.07,-1.04;P=0.000),triglycerides(TG)(WMD:-16.10 mg/dL,95％CI:-20.16,-12.05;P=0.000),total cholesterol(TC)(WMD:-14.00 mg/dL,95％CI:-20.46,-7.55;P=0.000),low-density lipoprotein cholesterol(LDL-C)(WMD:-7.03 mg/dL,95％CI:-9.25,-4.81;P=0.000),fasting plasma glucose(FPG)(WMD:-16.57 mg/dL,95％CI:-20.39,-12.74;P=0.000),hemoglobin Ale(HbAlc)(WMD:-0.44％,95％CI:-0.68,-0.20;P=0.000),insulin(standardized mean difference(SMD):-0.37,95％CI:-0.53,-0.21;P=0.000),homeostatic model assessment of insulin resistance(HOMA-IR)(WMD:-1.05,95％CI:-1.56,-0.54;P=0.000),C-reactive protein(CRP)(SMD:-0.35,95％CI:-0.57,-0.13;P=0.002),tumor necrosis factor-α(TNF-α)(SMD:-1.07,95％CI:-1.57,-0.56;P=0.000),interleukin-6(IL-6)(SMD:-0.37,95％CI:-0.61,-0.13;P=0.003)levels,they also increased the high-density lipoprotein cholesterol(HDL-C)(WMD:3.70 mg/dL,95％CI:1.80,5.60;P=0.000)levels in T2DM patients,as compared to the placebo groups.This meta-analysis supports the use of probiotic/prebiotic/synbiotic supplementation as an adjunctive therapy to improve blood pressure,glycemic control parameters,lipid profile and inflammatory markers in patients with T2DM,which are well-known cardiovascular risk factors.
