ABSTRACT

Com o objetivo de contribuir para um melhor conhecimento do envolvimento das infecções pelos vírus das hepatites B e C, na etioepidemiologia do CHC na Amazônia Oriental, estudou-se 36 pacientes em Belém-PA. Foram avaliados marcadores sorológicos e a pesquisa do HBV-DNA e HCV-RNA pela reação em cadeia da polimerase. Observou-se etilismo em 33,3% e cirrose em 83,3%. Marcadores sorológicos das infecções pelo HBV e HCV foram encontrados respectivamente em 88,9% e 8,3%. O HBsAg foi encontrado em 58,3%; anti-HBc em 86%; anti-HBe em 85,7; HBeAg em 9,5%; anti-HBc IgM em 57,1%. O HBV-DNA foi detectado em 37,7% e em 65% dos HBsAg positivos; o HCV-RNA em 8,5% e em 100% dos anti-HCV positivos. AFP esteve alterada em 88,9% e acima de 400ng/ml em 75% dos casos. Conclui-se que a infecção pelo HBV parece ter importância na etiologia do CHC e ressalta-se a importância de implementar programas de vacinação e detecção precoce do tumor.


In order to contribute to a better understanding of the possible role of hepatits B and C in the etiopathogenis of HCC in the East Amazon, there were studied 36 patients in Belém/PA. Serological hepatitis markers were evaluated and polymerase chain reaction assays were used to detect HBV-DNA and HCV-RNA. Alcohol abuse was observed in 33.3% and cirrhosis in 83.3%. In 88.9% of the sample, one or more hepatitis B markers were positive. Also, 8.3% those patients had anti-HCV simultaneously positive. The HBsAg serological test was positive in 58.3%; anti-HBc in 86%; anti-HBe in 85.7%; anti-HBe in 9.5%; IgM anti-HBc in 57.1%. The HBV DNA was found in 37.7% and in 65% of the HBsAg positive. The HCV RNA was detected in 8.5% and in 100% of' the patients positive to anti-HCV. The AFP was above the normal value in 88.9% of patients, with levels up to 400ng/ml in 75% of them. In conclusion, hepatitis B virus infection seems to be important in the etiology of HCC and improving measures such immunization and screening in the risk population should be emphasyzed.
