Core Tip

Core tip: The prevalence of hepatic steatosis is increased in the last three decades concomitantly with the increased prevalence of pediatric obesity. Non-alcoholic fatty liver disease (NAFLD) is the most common form of liver disease in children. The PNPLA3 rs738409 and the glucokinase regulatory protein rs1260326 are the strongest variants associated with fatty liver in paediatrics. Important risk factors are obesity, insulin resistence, gender, ethnicity and excessive dietetic intake of n-6 polyunsatured fatty acids and fructose. New pharmacological approaches are object of study, in NAFLD children poorly adherent to or being unresponsive/partially responsive to lifestyle changes.
