ABSTRACT

The risk of HBV infections in health workers and the different prevalence according to the hospital activities has been shown in a great number of papers. In order to establish the prevalence of serological HBV markers in health workers fron high complexity hospital, we have analyzed 730 inquiries refilled in the period 1994-1995 before receiving the antihepatitis B vaccine. We studied 730 health workers, 282 (38.8%) males and 447 (61.2%) females with a mean age of 40.1 years old. We found 75/730 (10.2) serums antiçHBc reactives. The found prevalence was significantly larger than the one found in blood donors. The analysis of the prevalence according to the hospital activities showed that the infirmary personnel is the only with anti-HBc prevalence significantly superior to the blood donors, and the other health workers prevalence. Differences in the anti-HBc prevalence between the physicians specialties were not found. Our results agree with other publications that clearly show that health workers are a risk group for HBV infection. However, what attracts attention in the analyzed population is that the only ones with anti-HBc prevalence significantly superior to the blood donors' and the other health workers prevalence were the nurses, suggesting that nurses are the only health workers that have risk of HBV infections.

ABSTRACT

El mayor riesgo de contagio de HBV en trabajadores de la salud y la distinta prevalencia según las categorias del personal ha sido demostrada en numerosos trabajos. Para evaluar la prevalencia de marcadores serológicos de infección por HBV en un hospital de alta complejidad, se analizaron retrospectivamente 730 encuestas prevacunales anti HBV realizadas en el período 1994-1995. La muestra estudiada se integró con 283 (38,8 por ciento) hombres y 47 (61,2 por ciento) mujeres que tenían una média de edad de 40.1 años. A la totalidad (730) se le investigó la presencia sérica de anti-HBc, 75 (10.2 por ciento) resultaron positivos siendo este valor significativamente mayor de la población general. El análisis de la prevalencia según la ocupación comparando los grupos en forma independiente con I grupo control y con el resto del personal hospitalario que los enfermeros son los únicos con prevalencia de enti-HBc significativamente mayor que la población general y que el resto del personal hospitalario. No se halló diferencia estadística entre las distintas especialidades del grupo de los médicos. Nuestros resultados son coincidentes con la literatura y muestran claramente que el personal sanitario constituye un grupo de riesgo de infección por HBV. A pesar de esta similitud, llama la atención que el único grupo de esta serie que presentó valores de prevalencia mayores a los de la población general y al resto del personal sanitario, fué el de enfermeros, sugiriendo que dicha ocupación seria la única que tendría riesgo de infección por HBV.

ABSTRACT

In order to have knowledge on the histopatologic characteristics of the HCV infections in our geographical area and its relation with some epidemiologic variables, a serie of 54 biopsias of Anti HCV (R) patients was analized. The histologic lesions found in this study correspond mostly to patients with relatively early infections, on the contrary to other studies of the some kind. The most frequent histopathologic diagnosis were crhonic hepatitis 38/54 (70.4 percent), steatosis 4/54 (7.4 percent) and 12/54 (22.2 percent) with no changes. The presence of lymphoid follicles in the portal tracts was the most frequent histological change in this series (66.7 percent), followed by the alteration in bile ducts (53.7 percent); they occurred in a significally higher proportion in the biopsies which had a diagnosis of chronic hepatitis (p=0.02) (p=0.000002). The presence of steatosis and acidophilic bodies in the acinus were found in nearly one third of the biopsies. This findings suggest that the hepatic damage in the anti HCV reactive patients might take through inmunologic mechanisms and citopatic direct action. It was not found that histologic changes produced by HCV might differ according to epidemiologic variables (post-tranfutional, drug abuse IV and sporadic).

The presence of steatosis and acidophilic bodies in the acinus were found in nearly one third of the biopsies. This findings suggest that the hepatic damage in the anti HCV reactive patients might take place through immunologic mechanisms and cytopathic direct action. It was not found that histologic changes produced by HCV might differ according to epidemiologic variables (post-transfusional, drug abuse i.v. and sporadic).

ABSTRACT

The aim of this prospectively designed study is to analyse the prevalence of HBV and HCV infections in 115 chronic alcohol abusers, their relation to epidemiological variables, and their meaning in pathogenesis and severity of alcoholic liver injury. A prevalence of 13.9% anti-HBc and 20.0% anti-HCV reactivity (EIA II) were found, significantly higher that found in blood donors (3.75 and 0.65% respectively). It is striking our finding of 69.6% "sporadic" type of HCV infection. Histological diagnostic of chronic hepatitis was done in 3 cases, all of them reactive to anti-HCV, enhancing the ethiologic role of HCV in the so called "alcoholic chronic hepatitis". No differences in histological final diagnosis were found related to HBV and HCV markers reactivity, suggesting no clear influence of viral infections on the severity of liver damage in alcoholics in our series. Neither anti-HCV positivity ratio seemed have to influence on these results. Despite a high prevalence of HBV and HCV infection in chronic alcohol abusers, our finding suggest no clear role for them in histological damage.

ABSTRACT

Se presenta un estudio prospectivo sobre 115 alcohólicos crónicos destinado a conocer la prevalencia de marcadores séricos de virus de hepatitis B y C (HBV) (HCV) en ese tipo de pacientes, la asociación de las infecciones por HBV y HCV con diversas variables epidemiológicas y la influencia de esos virus sobre el grado de lesión hepatica. Se halló una prevalencia de marcadores de HBV del 13.9 por ciento de Anti HCV del 20.0 por ciento ambas significativamente mayores a las de los donantes de sangre. La alta prevalencia de Anti HCV en esta serie de alcohólicos, con un 69.6 por ciento de formas espor dicas de infección, resulta difícil de justificar. El diagnóstico histológico de hepatitis crónica (HC) realizado en 3 de los 115 pacientes estudiados, recayó la totalidad de las veces sobre pacientes Anti HCV (R), demonstrando una clara asociación de las HC con el HCV en los alcohólicos crónicos. Con respecto a los otros diagnósticos histológicos, no se halló diferencias entre los pacientes con sueros reactivos para algún marcador del HBV o para el Anti HCV y aquellos con sueros no reactivos; sugiriendo que el HBV y el HCV no influyen en el grado de lesión hep tica de los alcohólicos crónicos. No hallamos que la relación de positividad del Anti HCV en los 23 pacientes fuera diferente según los distintos diagnósticos histopatológicos. Tampoco apreciamos en esta serie, que la cirrosis acurriera mas tempranamente en los Anti HCV R que en los NR; discrepando con algunas comunicaciones recientes.
