Abstract

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in the world. Oral administration of symbiotic and Vitamin E has been proposed as an effective treatment in NAFLD patients. This study was carried out to assess the effects of symbiotic and/or Vitamin E supplementation on liver enzymes, leptin, lipid profile, and some parameters of insulin resistance (IR) in NAFLD patients. Materials and Methods: We randomly assigned sixty NAFLD adult patients to receive (1) symbiotic twice daily + Vitamin E-like placebo capsule; (2) 400 IU/d Vitamin E + symbiotic-like placebo; (3) symbiotic twice daily + 400 IU/d Vitamin E; and (4) symbiotic-like placebo + Vitamin E-like placebo for 8 weeks. Results: Symbiotic plus Vitamin E supplementation led to a significant decrease in concentrations of liver transaminase (P � 0.05). Mean difference of apolipoprotein A-1 was more significant in symbiotic group compared to control. However, mean difference of apolipoprotein B100/A-1 was only significant in symbiotic group compared to control. At the end of the study, significant differences in total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) were seen between the symbiotic plus Vitamin E and control groups (P < 0.001). Furthermore, intake of symbiotic plus Vitamin E supplements led to a significant decrease in concentrations of triglycerides (TG) after the intervention. Significant differences in leptin, fasting blood sugar (FBS), and insulin levels were seen between the symbiotic plus Vitamin E and control groups at the end of the study (P < 0.001). In contrast, symbiotic and/or Vitamin E supplementation did not affect high-density lipoprotein cholesterol and homeostasis model assessment for IR levels. Conclusion: In our study, symbiotic plus Vitamin E supplementation was the most effective treatment in lowering liver enzymes, leptin, FBS, insulin, TG, TC, and LDL-C among NAFLD patients. © 2016 Journal of Research in Medical Sciences.
