These studies demonstrated improvement in biochemical profiles , with a decline in or normalization of liver enzymes .
However , some concerns have been raised regarding the use of vitamin E in patients with NASH due to its adverse effects profile and lack of significant improvement in hepatic fibrosis .
There has been a growing interest in the role of vitamin E supplementation in the treatment and /or prevention of nonalcoholic fatty liver ( NAFLD ) .
Furthermore , histological assessment showed favorable outcomes in lobular inflammation and hepatic steatosis following treatment with vitamin E. Current guidelines regarding the use of vitamin E in the setting of NAFLD recommend that vitamin E-based treatment be restricted to biopsy-proven nondiabetic patients with NASH only .
Lifestyle intervention and antioxidant therapy in children with nonalcoholic fatty liver disease: a randomized, controlled trial.
UNLABELLED No proven treatment exists for nonalcoholic fatty liver disease ( NAFLD ) in children and adolescents . We sought to determine the efficacy of lifestyle intervention with or without antioxidant therapy in pediatric NAFLD . A total of 53 patients ( age 5.7 - 18.8 years , 37 boys ) were included .  Lifestyle intervention consisting of a diet tailored to the patient 's calorie needs , and increased physical activity was prescribed in all . Patients were concomitantly r and omized to alpha-tocopherol 600 IU/day plus ascorbic acid 500 mg/day ( n = 25 ) or placebo ( n = 28 ) , and treated for 24 months . The study was an extension of a previous study aim ed at evaluating the effect of 12-month lifestyle intervention and antioxidant therapy on serum levels of aminotransferases . The primary end point of the present study was change in liver histology on repeated biopsy at 24 months . Secondary end points were changes in body weight , liver enzymes , and insulin sensitivity indices on 2-hour oral glucose tolerance test . The amount of weight lost at 24 months was similar in the placebo and antioxidant groups ( -4.75 [ range , -16 - 4.0 ] versus -5.5 [ range , -12.2 - 0.4 ] kg , respectively , P = 0.9 ) . A significant improvement occurred in the grade of steatosis , lobular inflammation , and hepatocyte ballooning , and in the NAFLD activity score in both groups . Levels of aminotransferases , triglycerides , cholesterol , fasting glucose , and insulin , and insulin sensitivity indices improved significantly as well . The improvement in all these parameters was not significantly different between the two groups . CONCLUSION Lifestyle intervention with diet and increased physical activity induces weight loss and is associated with a significant improvement in liver histology and laboratory abnormalities in pediatric NAFLD . Alpha-tocopherol plus ascorbic acid does not seem to increase the efficacy of lifestyle intervention alone
