[Nonalcoholic steatohepatitis, the enigma of bad progression]. / Esteatohepatitis no alcohólica, el enigma de una mala evolucion.

Still, very little is known about the precise pathogenetic mechanisms, the triggering events and in particular, the evolution and treatment of nonalcoholic steatohepatitis (NASH). It is part of the broad spectrum of nonalcoholic fatty liver diseases (NAFLDs). Mainly, it has been reported as a benign disease, associated with metabolic disorders commonly occurrence en the general population. Nevertheless, the syndrome can lead to cirrhosis, liver failure or hepatocellular carcinoma, requiring liver transplantation. We present one patient with diagnosis of NASH, who was treated initially for overweight, HTA and hyperlipaemia with incompleted response and who showed a quickly progress to cirrhosis but no cause of liver decompensated disease could be identified. Currently she is at end-stage waiting a liver transplantation. Controlled and multicentric studies with the same definition of NASH and the study end-points are needed, and will provide information about diagnosis features and novel therapies to early management of the disease.

Esteatohepatitis no alcohólica, el enigma de una mala evolucion / Nonalcoholic steatohepatitis, the enigma of bad progress

Hasta ahora poco se sabe acerca de la patogenia, los desencadenantes y en particular de la evolución y terapia de la esteatohepatitis no alcohólica (EHNA). Incluída en el amplio espectro de enfermedades del hígado graso no alcohólicas. Se ha considerado una enfermedad mayoritariamente benigna y asociada a alteraciones metabólicas muy prevalentes en la población general. Sin embargo no es raro que progrese a cirrosis, insuficiencia hepática o hepatocarcinoma que precise transplante hepático. Presentamos el caso de una paciente que diagnosticamos de EHNA, al inicio con respuesta parcial y tardía al tratamiento para el sobrepeso, la HTA y la hiperlipidemia, pero con una evolución rápida a cirrosis hepática sin identificarse ningún factor desencadenante. Actualmente es candidata a transplante hepático.Son necesarios estudios multicéntricos y controlados, con la misma definición de EHNA y objetivos comunes que aportarán información sobre datos diagnósticos y nuevas terapias para el manejo precoz de la enfermedad
