RESUMEN
El Hígado graso no alcohólico (HGNA) se define como la infiltración grasa del hígado mayor al 5% de su peso incluyendo un amplio espectro de trastornos hepáticos que van desde la esteatosis simple hasta la esteatohepatitis pudiendo progresar a fibrosis, cirrosis, carcinoma hepatocelular y muerte. Para establecer el diagnóstico deben encontrarse hallazgos histológicos o imagenológicos, excluirse una causa secundaria de esteatosis y existir asociación con el Síndrome metabólico, en donde la Resistencia a la insulina es la piedra angular en su fisiopatología. Su prevalencia va en aumento de la mano con la epidemia de la obesidad a nivel mundial. La biopsia hepática sigue siendo el patrón de oro, sin embargo han surgido marcadores serológicos como índices predictivos de fibrosis así como métodos imagenológicos para lograr de manera no invasiva seleccionar a aquellos pacientes candidatos a biopsia hepática. El tratamiento de elección siguen siendo los cambios en el estilo de vida. La Vitamina E y las Tiazolidinedionas son los únicos que han demostrado evidencia en Ensayos Clínicos Controlados. Otros medicamentos serán discutidos así como drogas promisorias(AU)
ABSTRACT
Non-alcoholic fatty liver disease (NAFLD) is defined as fatty infiltration of the liver that is more than 5% of its weight including a wide spectrum of liver disorders ranging from simple steatosis to steatohepatitis, which can progress to fibrosis, cirrhosis, hepatocellular carcinoma and death. To establish the diagnosis histological or imaging findings to exclude a secondary cause of steatosis and have an association with metabolic syndrome, where insulin resistance is a cornerstone in its pathophysiology. Its prevalence is increasing with the obesity epidemic worldwide. Liver biopsy remains the gold standard; however serological markers have emerged as predictive indices of fibrosis and imaging methods to achieve noninvasively select candidates for liver biopsy. The treatment of choice remains the changes in lifestyle. Vitamin E and hiazolidinediones have shown evidence in Randomized Clinical Trials. Other medicines will be discussed as well as promising drugs. The present review aims to update the current information of this entity in terms of epidemiology, etiology, diagnosis and treatment(AU)
