Curcumin Offers No Additional Benefit to Lifestyle Intervention on Cardiometabolic Status in Patients with Non-Alcoholic Fatty Liver Disease.

Cardiovascular disease (CVD) is the leading cause of death in patients with non-alcoholic fatty liver disease (NAFLD). Curcumin has been shown to exert glucose-lowering and anti-atherosclerotic effects in type 2 diabetes. Hence, we investigated curcumin's effects on atherogenesis markers, fatty liver, insulin resistance, and adipose tissue-related indicators in patients with NAFLD. In this secondary analysis of a 12-week randomized controlled trial, fifty-two patients with NAFLD received lifestyle modification. In addition, they were randomly allocated to either the curcumin group (1.5 g/day) or the matching placebo. Outcome variables (assessed before and after the study) were: the fatty liver index (FLI), hepatic steatosis index (HSI), fatty liver score (FLS), BMI, age, ALT, TG score (BAAT), triglyceride glucose (TyG) index, Castelli risk index-I (CRI-I), Castelli risk index-II (CRI-II), TG/HDL-C ratio, atherogenic coefficient (AC), atherogenic index of plasma (AIP), lipoprotein combine index (LCI), cholesterol index (CHOLINDEX), lipid accumulation product (LAP), body adiposity index (BAI), visceral adiposity index (VAI), metabolic score for visceral fat (METS-VF), visceral adipose tissue (VAT), and waist-to-height ratio (WHtR) values. The TyG index decreased in the curcumin group and increased in the placebo group, with a significant difference between the groups (p = 0.029). However, a between-group change was not significant after adjustment for multiple testing. Other indices were not significantly different between the groups either before or after multiple test correction. After the intervention, there was a lower number of patients with severe fatty liver (FLI ≥ 60) and metabolic syndrome in the curcumin group compared to the placebo (p = 0.021 and p = 0.012, respectively). In conclusion, curcumin offers no additional cardiometabolic benefits to lifestyle intervention in patients with NAFLD.

Beneficial effects of probiotic and synbiotic supplementation on some cardiovascular risk factors among individuals with prediabetes and type 2 diabetes mellitus: A grade-assessed systematic review, meta-analysis, and meta-regression of randomized clinical trials.

Previous studies suggested that probiotics/synbiotics administration exerts some beneficial effects on cardiometabolic risk factors. However, the results from trials have been inconsistent. This study aimed to identify the impact of probiotic and synbiotic supplements on cardiovascular health factors in patients with type 2 diabetes mellitus (T2DM) and prediabetes We searched PubMed/MEDLINE, Web of Science, and Scopus up to February 2022 to identify eligible RCTs. Estimating 95 % confidence (CI) and the weighted mean difference (WMD) for weight, body mass index (BMI), waist circumferences (WC), triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), systolic blood pressure (SBP), and diastolic blood pressure (DBP), the random-effects model was used. In the current meta-analysis, 54 RCTs were included. With the probiotic/synbiotics intervention, several parameters changed significantly, including weight (WMD: -0.38, 95 % CI: -0.63 to -0.12 Kg), TG (WMD: -19.08, 95 % CI: -27.65 to -10.51 mg/dl), TC (WMD: -10.46, 95 % CI: -15.19 to -5.72 mg/dl), LDL-C (WMD: -4.87, 95 % CI: -7.65 to -2.09 mg/dl), HDL-C (WMD: -2.70, 95 % CI: 1.33-4.07 mg/dl), SBP (WMD: -3.81, 95 % CI: -6.24 to -1.38 mmHg), and DBP (WMD: -2.01, 95 % CI: -3.12 to -0.91 mmHg). In the subgroup analysis, probiotics/synbiotics supplementation resulted in a greater change in lipid profile components in T2DM patients. Weight and BMI reduced only after synbiotic supplementation. We found that the administration of probiotics and synbiotics had beneficial effects on lipid profiles, anthropometric indices, and blood pressure in individuals with T2DM.
