RESUMEN
Introducción El virus de la hepatitis E (VHE) es el principal agente causal de hepatitis no-A no-B de transmisión entérica. El incremento de casos autóctonos y la elevada prevalencia detectada en el ganado porcino sugieren la posibilidad de la existencia de un reservorio animal. El objetivo de este trabajo es determinar la presencia del VHE, de anticuerpos anti-VHE de clase IgG e IgM así como los factores de riesgo en individuos sanos con y sin exposición a ganado porcino. Métodos Se incluyeron un total de 212 individuos, 113 con exposición y 99 sin exposición a ganado porcino. En todos los sueros se determinó la presencia del ARN-VHE y anticuerpos anti-VHE IgG e IgM. Las muestras positivas para anti-VHE IgM e IgG se confirmaron por inmunoblot. Resultados El ARN-VHE y los anticuerpos anti-VHE IgM no se detectaron en ninguna muestra. De las 212 personas analizadas, 25 (11,8%) presentaron anti-VHE IgG, siendo 21 (18,6%) expuestos y 4 (4%) no expuestos a ganado porcino (p=0,004); 19 personas de todos los analizados (12,8%) habían viajado al extranjero en el último año (p=0,507). En cuanto a los datos de los 25 individuos que presentaban anti-VHE IgG, ninguno de ellos había consumido marisco crudo (p=0,999); 23 (12,6%) consumieron verduras crudas (p=0,387); y 12 (30%) consumían habitualmente agua no tratada (p=0,008).Conclusiones Los datos obtenidos en este estudio sugieren que la infección por el VHE puede tratarse como una enfermedad ocupacional en trabajadores del sector porcino y que deberían tomarse las medidas higiénico-sanitarias correspondientes en este grupo para disminuir la exposición al VHE (AU)
ABSTRACT
Introduction Hepatitis E virus (HEV) is the main causative agent of enterically transmitted non-A non-B hepatitis with a self-limiting clinical presentation in humans. The increasing number of non-immigrant cases of hepatitis E and the high prevalence detected in pigs suggested that this species is a reservoir. Several studies have been published describing differences in the prevalence of anti-HEV antibodies between people exposed and not exposed to pigs, but the risk factors for the acquisition of the virus have not been well studied. The aim of this work was to study the prevalence of hepatitis E virus (HEV), IgG and IgM antibodies anti-HEV and the risk factors for the acquisition of this virus in a populations exposed and unexposed to pigs.MethodsSera from 212 people were tested for the presence of RNA-HEV, IgG and IgM antibodies anti-HEV. Positive results obtained using ELISA assays were confirmed by western-blot.ResultsRNA-HEV and IgM anti-VHE were not detected in any of the individuals. Twenty-five samples (11.8%) showed IgG anti-HEV, 21 (18.6%) persons in contact with pigs and 4 (4%) unexposed individuals (P=0.004); 19 (12.8%) had travelled out of Spain in the last year (P=0.507). None of the 25 seropositive people had consumed raw shellfish (P=0.999), whereas 23 (12.6%) had consumed raw vegetables (P=0.387) and 12 (30%) usually drank untreated water (P=0.008).ConclusionThese data support that HEV infection should be treated as an occupational disease illness in pig workers. Therefore, systematic application of hygiene measures in this group is highly recommended to avoid exposure to this virus (AU)
