ABSTRACT

El diagnóstico de la hepatitis autoinmune (HAI), se basa en una serie de criterios definidos por elGrupo Internacional de HAI (IAIHG) que permite clasificarla como HAI probable o definitiva. Un criterio clave para el diagnóstico de la HAI es la detección de ANA, SMA, y anti- LKM-1 por inmunofluorescencia indirecta. Otros anticuerpos menos frecuentes probados, pero de importancia diagnóstica en HAI pediátrica incluyen los anticuerpos tipo: citosol 1 hígado (LC-1), anti- citoplasma de los neutrófilos (ANCA) y el antígeno soluble hepático (SLA). La Ig G está usualmente elevada en ambos tipos de HAI, cerca del 15% de niños con HAI I y el 25% de niños con HAI tipo II tienen valores normales. La biopsia hepática es necesaria para establecer el diagnóstico de HAI.


The diagnosis of autoimmune hepatitis (HAI), is based on a set of criteria defined by the International HAI Group (IAIHG) that allows classified as a probable or definite HAI. A key criterion for the diagnosis of HAI is the detection of ANA, SMA, and anti-LKM-1 by indirectimmunofluorescence. Other less common antibodies tested, but important diagnostic tool in pediatric HAI include antibodies such as: liver cytosol 1 (LC-1), anti-neutrophil cytoplasmic (ANCA) and soluble liver antigen (SLA). The Ig G is usually high in both types of HAI, about 15% of children with HAI I and 25% of children with HAI type II are normal. Liver biopsy is necessary to establish the diagnosis of HAI.
