Resumen

Se ha investigado la prevalencia de los diferentes genotipos del virus de la hepatitis C (VHC) en el Área de Salud de Elche sobre un total de 281 pacientes estudiados entre marzo de 2000 y marzo de 2002. De ellos, 55 estaban coinfectados con el virus de la inmunodeficiencia humana (VIH).

Abstract

Se ha relacionado el genotipo con la carga viral y la coexistencia de infección por el VIH. Asimismo, se ha establecido la relación de estos parámetros con la presencia del antígeno del core del VHC.

Los resultados permiten establecer que el genotipo 1b es el que presenta mayor prevalencia (38,4%), seguido del genotipo 3a (23,1%). Los pacientes coinfectados por el VIH presentan menos infecciones debidas a genotipos del grupo 1 (p < 0,05).

Los pacientes infectados por el VIH presentan una mayor carga viral en todos los genotipos, sobre todo el genotipo 3. La detección del antígeno del core del VHC presenta una buena correlación con la determinación de la carga viral. Aunque todavía no ha sido suficientemente evaluada, la determinación del antígeno del core del VHC constituye una técnica sencilla que puede contribuir, en el futuro, a mejorar el manejo de los pacientes con hepatitis crónica por el VHC.

Abstract

We investigated the prevalence of the various genotypes of hepatitis C virus (HCV) in 281 patients evaluated between March, 2000 and March, 2002 in the health area of Elche. Of these patients, 55 were coinfected with human immunodeficiency virus (HIV).

The genotype was related to viral load and the co-existence of HIV infection. Likewise, the relationship between these parameters and the presence of the HCV core antigen was established.

The results indicate that genotype 1b was the most prevalent (38.4%) followed by genotype 3a (23.1%). Patients coinfected with HIV presented fewer infections due to group 1 genotypes (p < 0.05).

Patients with HIV presented a greater viral load in all the genotypes, with genotype 3 presenting a high viral load. Detection of the HCV core antigen showed a close correlation with viral load determinations. Although not yet sufficiently assessed, determination of the HCV core antigen constitutes a simple technique that could eventually contribute to improving the management of patients with chronic HCV hepatitis.
