Background: Having a stroke, which is a devastating condition, is a major cause of deaths worldwide and is also accountable for long time disability with high personal and social cost in adults. Hyperlipidemia plays an important role in atherothrombosis, which is the precursor to stroke. One way for decreasing the risk of a stroke is treatment of dyslipidemia. Alpha-lipoic acid (ALA) is an eight-carbon, sulfur-containing compound with antioxidant properties and effective in protecting against hypercholesterolemia and hepatic fat accumulation.Objectives: We designed this trial to scrutinize the possible effects of ALA consumption on lipid profiles in patients who experienced a stroke.Methods: In this randomized, double blind, placebo-controlled clinical trial, 67 patients who experienced a stroke were randomly allocated into 2 groups (taking a 600 mg ALA supplement or placebo daily for 12 weeks). The triglyceride (TG), total cholesterol (TC), LDL-cholesterol (LDL), and HDL-cholesterol (HDL) were measured and LDL-cholesterol/ HDL-cholesterol (LDL/ HDL) as well as total cholesterol/ HDL-cholesterol (TC/ HDL) were calculated before and after intervention in this study. Dietary intake and statistical analyses were carried out using the N4 and SPSS16 software, respectively.Results: Primary features were similar in the intervention and placebo groups (P < 0.05). After the intervention period, serum levels of TG (123.21 ± 49.63 vs. 152.97 ± 58.83) (P < 0.001), TC (148.67 ± 37.71 vs. 174.35 ± 36.86) (P < 0.001), and LDL (85.09 ± 23.81 vs. 107.56 ± 31.73) (P = 0.002) decreased, and HDL level (58±9.33 vs. 42.97 ± 8.07) (P < 0.001) increased significantly in ALA group compared with the placebo. In addition, LDL/ HDL (P < 0.001) and TC/ HDL (P < 0.001) reduced significantly.Conclusions: Results of this trial indicated that 12 weeks of supplementation with 600 mg alpha-lipoic acid has beneficial effects on lipid profile (TG, TC, LDL, HDL, LDL-/HDL, and TC/HDL) in patients who have experienced a stroke.

Background: Regarding the growing prevalence of non-alcoholic fatty liver disease, concentrating on various strategies for its prevention and management seems necessary.Objectives: This study aimed to assess the effects of synbiotic administration on body composition and lipid profile in patients with NAFLD.Methods: Eighty patients with NAFLD participated in this randomized, double-blind, placebo-controlled clinical trial (from March to July 2014) in Iran. Based on AST and ALT as main variables of the study, 34 patients were required in each group (power 80% and α = 5%). Considering a 20% sample loss, 80 patients were enrolled. Synbiotic supplement in form of a 500 mg capsule (containing 7 species of probiotic bacteria and Fructooligosaccharides) was administrated to patients in the intervention group and those in the placebo group received 1 placebo capsule daily for 8 weeks. At the baseline and the end of the study, body composition and lipid profile were evaluated.Results: A significant reduction was observed in weight (P = 0.001), body fat (P = 0.02), and total cholesterol (P = 0.04) within the synbiotic group. On the other hand, WC (P = 0.02), total cholesterol, and LDL-c (P = 0.04 and P = 0.001, respectively) were significantly increased in the placebo group. TG, HDL-c, and FBG levels remained statistically unchanged in both groups. Significance betweengroup differences were seen in total cholesterol (P = 0.01), LDL (P = 0.01), weight, WC, and body fat after adjustment for energy intake (P = 0.05).Conclusions: Synbiotic supplementation may improve lipid profile and body composition in patients with NAFLD and might be useful in prevention of the disease progression.
