ABSTRACT

Objetivo: determinar a soroprevalência de anticorpos anti-HAV total em pacientes com hepatite crônica C,correlacionando-a aos aspectos clínico-epidemiológicos e à necessidade de vacina contra a hepatite A. Método.: no período de janeiro a julho de 2004, selecionaram-se pacientes portadores de anti-HCV e RNA-HCV positivos com diagnóstico de hepatite crônica, cirrose e carcinoma hepatocelular do Programa de Hepatopatias Crônicas da Fundação Santa Casa de Misericórdia do Pará para a realização de sorologia anti-HAV total. Resultados: testados 243 pacientes dos quais 177 (72,8%) eram do sexo masculino e 200 (84,4%) procediam de zona urbana. Deste total, 220 (90,5%) eram anti-HAV positivos. Comparando-se os grupos anti-HAV positivo e negativo, obteve-se média de idade de 46,9 anos (DP=13,86) e 22,2 anos (DP=12,67; p<0,0001), respectivamente. Dentre aqueles com mais de 35 anos, cinco (2,7%) eram anti-HAV negativos (p<0,0001). Não houve diferença quanto à distribuição por sexo nem quanto aos diagnósticos entre os dois grupos. Conclusão: foi alta a prevalência de anti-HAV total (90,5%) em pacientes cronicamente infectados pelo vírus da hepatite C, com menor média de idade no grupo anti-HAV negativo em relação ao positivo (22,2 versus 46,9), sugerindo que a vacinação contra a hepatite A na população estudada, deveria ser feita com base na triagem sorológica prévia, principalmente após os 35 anos de idade.


Background: there are evidences that hepatitis A virus (HAV) infection in patients with pre-existing liver disease (CLD) exhibits more serious outcomes, including fulminant hepatitis and the risk is greater in those with chronic hepatitis C (CHC). Aim: to access seroprevalence of total anti-HAV antibodies in patients with CHC correlating it to clinical-epidemiological features and need of vaccination against HAV Methods: From January to July 2004, anti-HCV (Elisa 3th generation) and HCV-RNA (Ampticor Roche) positive carriers who had chronic hepatitis, liver cirrhosis and hepatocellular carcinoma were selected to be tested to total anti-HAV (Elisa) from the CLD Program of Santa Casa de Misericórdia do Pará Hospital. Results: Two hundred forty-three patients were tested being 177 (72.8%) male and 200 (84.4%) from urban zone. At all, 220 (90.5%) were" anti-HAV positives. The mean age was 46.9 (SD=13.8) and 22.2 years (SD=12.7) to positive and negative anti-HAV groups, each one (p<0,0001). Among those patients older than 35 years, 5 (2.7%) were HAV negative (p<0.0001). There was no difference statistically significant between sexes and diagnostics. Conclusion: the total anti-HAV prevalence was high (90.5%) among patients chronically infected by hepatitis C virus and the anti-HAV negative group showed a lower mean age than positive one (22.2 vs. 46.9). These data suggest that hepatitis A vaccination in Brazilian Amazonia should be considered with a previous serological screening mainly in patients older than 35 years.
