Hydroxytyrosol and Vitamin E in Pediatric NASH

Summary

Non-alcoholic fatty liver disease (NAFLD) has reached epidemic proportions and is rapidly becoming the one of most common causes of chronic liver disease in children. The pathogenesis of NAFLD is generally considered the result of a series of liver injuries, commonly referred as "multi-hit" hypothesis. Several studies suggest that inflammatory pathways and oxidative stress could be responsible of disease progression to non-alcoholic steatohepatitis (NASH). Hydroxytyrosol is a simple phenolic compound naturally occurring in olive and olive oil with antioxidant properties. Some studies have demonstrated that hydroxytyrosol show several anti-inflammatory and anti-atherogenic activities, such as the inhibition of LDL oxidation and platelet aggregation. Alpha tocopherol (Vitamin E) is the most studied anti-oxydant in pediatric NAFLD with conflicting results. It inhibits proinflammatory cytokine production and attenuates the release of profibrogenic agents and liver collagen. The purpose of this interventional study is to evaluate the efficacy and tolerability of Hydroxytyrosol and Vitamin E in the treatment of children with biopsy-proven NASH.
