BACKGROUND
This study was conducted to evaluate the effects of probiotic supplementation on metabolic profiles in diabetic patients with coronary heart disease (CHD).
METHODS
This randomized, double-blind, placebo-controlled trial was performed among 60 diabetic patients with CHD, aged 40-85 years at a cardiology clinic in Kashan, Iran, from October 2017 through January 2018. Patients were randomly divided into two groups to take either probiotic supplements (n = 30) or placebo (n = 30) for 12 weeks. Fasting blood samples were taken at the beginning of the study and after the 12-week intervention to determine related markers.
RESULTS
After 12-week intervention, probiotic supplementation significantly decreased fasting plasma glucose (β - 20.02 mg/dL; 95% CI - 33.86, - 6.17; = 0.005), insulin (β - 2.09 µIU/mL; 95% CI - 3.77, - 0.41; = 0.01), insulin resistance (β - 0.50; 95% CI - 0.96, - 0.03; = 0.03) and total-/HDL-cholesterol ratio (β - 0.27; 95% CI - 0.52, - 0.03; = 0.02), and significantly increased insulin sensitivity (β 0.008; 95% CI 0.001, 0.01; = 0.02) and HDL-cholesterol levels (β 2.52 mg/dL; 95% CI 0.04, 5.00; = 0.04) compared with the placebo. Moreover, probiotic supplementation led to a significant reduction in serum high sensitivity C-reactive protein (β - 0.88 mg/L; 95% CI - 1.39, - 0.38; = 0.001), and a significant elevation in total antioxidant capacity (β 108.44 mmol/L; 95% CI 47.61, 169.27; = 0.001) and total glutathione levels (β 45.15 µmol/L; 95% CI 5.82, 84.47; = 0.02) compared with the placebo. Probiotic supplementation did not affect other metabolic profiles.
CONCLUSIONS
Overall, we found that probiotic supplementation for 12 weeks had beneficial effects on glycemic control, HDL-cholesterol, total-/HDL-cholesterol ratio, biomarkers of inflammation and oxidative stress in diabetic patients with CHD.

背景
本研究旨在评估补充益生菌对冠心病（CHD）糖尿病患者代谢谱的影响。
方法
本随机、双盲、安慰剂对照试验于2017年10月至2018年1月在伊朗卡尚的一家心脏病诊所对60例年龄在40 - 85岁的冠心病糖尿病患者进行。患者被随机分为两组，分别服用益生菌补充剂（n = 30）或安慰剂（n = 30），为期12周。在研究开始时和12周干预后采集空腹血样以测定相关指标。
结果
经过12周干预，与安慰剂相比，补充益生菌显著降低了空腹血糖（β - 20.02mg/dL；95%CI - 33.86，- 6.17；P = 0.005）、胰岛素（β - 2.09µIU/mL；95%CI - 3.77，- 0.41；P = 0.01）、胰岛素抵抗（β - 0.50；95%CI - 0.96, - 0.03；P = 0.03）和总胆固醇/高密度脂蛋白胆固醇比值（β - 0.27；95%CI - 0.52，- 0.03；P = 0.02），并显著提高了胰岛素敏感性（β 0.008；95%CI 0.001，0.01；P = 0.02）和高密度脂蛋白胆固醇水平（β 2.52mg/dL；95%CI 0.04，5.00；P = 0.04）。此外，与安慰剂相比，补充益生菌导致血清高敏C反应蛋白显著降低（β - 0.88mg/L；95%CI - 1.39，- 0.38；P = 0.001），总抗氧化能力显著升高（β 108.44mmol/L；95%CI 47.61，169.27；P = 0.001）和总谷胱甘肽水平显著升高（β 45.15µmol/L；95%CI 5.82，84.47；P = 0.02）。补充益生菌未影响其他代谢谱。
结论
总体而言，我们发现补充益生菌12周对冠心病糖尿病患者的血糖控制、高密度脂蛋白胆固醇、总胆固醇/高密度脂蛋白胆固醇比值、炎症和氧化应激生物标志物具有有益影响。临床试验注册号http://www.irct.ir：IRCT2017082733941N5。
