title: [Nonalcoholic fatty liver disease in children].
abstract: Nonalcoholic fatty liver disease (NAFLD) is currently the most common cause of liver disease in children and adolescents in the United States of America (USA) and probably in the entire western hemisphere, due to the increase in the prevalence of overweight and obesity. Steatosis can progress to inflammation, fibrosis and even cirrhosis, which increases the morbidity and mortality associated to liver disease. In every overweight and obese child a thorough analysis should be performed including liver function tests and liver ultrasound, in order to establish a timely diagnosis. The liver biopsy is the most specific study to rule out other potentially treatable entities. It is necessary to count on non-invasive methods to detect children with NAFLD and identify those in risk of progression. Biomarkers related to inflammation, oxidative stress, apoptosis and fibrosis have been reported. The main goal of the treatment is to modify the life style, starting with a healthy diet and an increase of physical activity. Regarding pharmacological treatment, there is evidence of histological improvement with vitamin E use, as opposed to metformin, but more conclusive studies regarding this subject are needed.
