There is currently no specific treatment for non-alcoholic fatty liver disease (NAFLD) in children, but recent studies have shown that vitamin E may be effective. Therefore, we conducted a meta-analysis of trials in which vitamin E was used to treat paediatric NAFLD.

We searched the PubMed, Embase, Scopus and Cochrane Library databases to identify related articles published prior to March 2020 that examined the effect of vitamin E for the treatment of paediatric NAFLD.

The results showed that vitamin E significantly decreased low-density lipoprotein (LDL) and total cholesterol (TCHO) levels. However, no significant changes were found in other indicators, including body mass index (BMI), triglyceride (TG) levels, high-density lipoprotein (HLD) levels, fasting insulin levels, homeostatic model assessment (HOMA-IR), alanine transaminase (ALT) levels, aspartate aminotransferase (AST) levels, glutamate transpeptidase (GGT) levels, ballooning degeneration and fibrosis (P > 0.05). Although the P value of NAS was less than 0.05, the evidence was not strong enough. We also found that treatment with vitamin E significantly increased fasting glucose (FSG) levels if the intervention time was ≤12 months.

Vitamin E therapy can improve blood lipids to some extent, but its effect on children's liver function and liver tissue is not apparent, and the finding that this therapy increases FSG levels still needs more research.
