Introducción

La hepatitis C es una de las causas más frecuentes de enfermedad hepática crónica en nuestro medio. La mayoría de los pacientes que presentan una infección aguda por el virus de la hepatitis C (VHC) desarrollan hepatitis crónica, y sólo entre un 15 y un 30% se resuelven espontáneamente.

Pacientes y método

Se analizaron de forma retrospectiva las características clínicas, biológicas y virales, así como la tolerancia al tratamiento y el grado de repuesta sostenida, en 9 pacientes con hepatitis C aguda tratados con terapia combinada con interferón alfa más ribavirina durante 12-48 semanas.

Resultados

La media de alaninaminotransferasa (ALT) y bilirrubina total de los pacientes en el momento del diagnóstico fue de 1,469 U/l y 5,5 mg/dl, respectivamente. Todos los pacientes, excepto uno, estaban infectados por el genotipo 1b y presentaban una carga viral media de 634.924 U/ml. Al final del seguimiento, en 7 pacientes (77,7%) los valores de ARN-VHC fueron indetectables y los valores de ALT normales. La terapia fue bien tolerada excepto en 2 pacientes, uno de los cuales presentó un síndrome depresivo leve que fue controlado con medicación, y el otro una tiroiditis que obligó a la interrupción del tratamiento a las 12 semanas.

Conclusiones

A pesar de ser una serie reducida de pacientes, el tratamiento combinado con inteferón alfa más ribavirina parece conseguir una tasa de respuesta sostenida elevada, con una buena tolerancia y escasos efectos secundarios.

Introduction

Hepatitis C virus (HCV) is one of the most frequent causes of chronic liver disease in our environment. Most patients who present acute HCV infection develop chronic hepatitis, and only between 15 and 30% resolve spontaneously.

Patients and method

The clinical, biological and viral characteristics, as well as tolerance to treatment and level of response were retrospectively analyzed in nine patients with acute hepatitis C who underwent treatment with interferonalfa plus ribavirin for 12 to 48 weeks.

Results

The mean alanine-aminotransferase (ALT) and total bilirubin concentrations of patients at diagnosis was 1.469 U/l and 5.5 mg/dl, respectively. All the patients except one were infected with genotype 1b and presented a mean viral load of 634,924 U/ml. At the end of follow-up, in seven patients (77.7%) HCV-RNA levels were undetectable and ALT levels were normal. The therapy was well tolerated except in two patients: one presented a mild depressive syndrome that was controlled with drugs and the other presented thyroiditis, which led to treatment withdrawal at 12 weeks.

Conclusions

Despite the small number of patients, interferon alfa plus ribavirin seems to achieve a high, sustained response. The treatment was well tolerated and there were few adverse effects.
