ABSTRACT
ABSTRACT Background Occult hepatitis B infection is characterized by negative hepatitis B surface antigen (HBsAg) and also detectable hepatitis B virus (HBV) -DNA, with or without hepatitis B core antibody (anti-HBc). HBV reactivation in individuals under immunosuppressive therapy is critical, occurring in occult HBV. Objective In this study, we aimed to determine the prevalence of occult HBV infection among hepatitis B surface antigen negative in cancer patients before receiving chemotherapy. Methods Sera from 204 cancer patients who were negative for HBsAg, were tested for anti-HBc antibodies. The samples that were negative for HBsAg but positive for anti-HBc also examined for HBV-DNA by polymerase chain reaction (PCR). Results Of the 204 HBsAg negative blood samples, 11 (5.4%) samples were positive for anti-HBc antibodies. HBV-DNA was detected in 9/11 (81%) of anti-HBc positive samples. Occult HBV infection in hematological cancers was more than solid cancers, 4.8% and 4.3% respectively. There was no significant difference in HBc antibody positivity based on vaccination, previous blood transfusions, history of familial hepatitis or biochemical parameters (ALT, AST, total and direct bilirubin levels) (P>0.05). Conclusion Screening of occult HBV infection by HBsAg, HBV DNA and anti HB core antibody should be suggested as a routine investigation in cancer patients before receiving chemotherapy.
RESUMO
RESUMO Contexto A infecção oculta da hepatite B caracteriza-se por antígeno de superfície da hepatite B (AgHBs) negativo com vírus detectável da hepatite B (HBV) -DNA, com ou sem anticorpo de núcleo da hepatite B (anti-HBc). A reativação do HBV em indivíduos sob terapia imunossupressora é crítica, originando a infecção oculta pelo VHB. Objetivo Este estudo teve como objetivo determinar a prevalência de infecção oculta pelo VHB entre em pacientes com câncer e com antígeno de superfície da hepatite B negativo antes de receber quimioterapia. Métodos Soro de 204 pacientes com câncer que foram negativos para AgHBs, foram testados para anticorpos anti-HBc. As amostras que foram negativos para AgHBs, mas positivo para anti-HBc foram também examinadas para HBV-DNA, por reação em cadeia da polimerase. Resultados Entre 204 amostras de sangue AgHBs negativas, 11 (5,4%) foram positivos para anticorpos anti-HBc. HBV-DNA foi detectado em 9/11 (81%) das amostras positivas de anti-HBc. Infecção oculta de VHB em câncer hematológico foi maior que em cânceres sólidos, 4,8% e 4,3% respectivamente. Não houve diferença significativa na positividade anti-HBc, com base na vacinação, transfusões de sangue anteriores, história de hepatite familiar ou parâmetros bioquímicos (ALT, AST, total e níveis de bilirrubina total) (P & gt; 0,05). Conclusão A triagem de infecção oculta por AgHBs, HBV-DNA e anti-anticorpo de núcleo HB deve ser sugerida como uma investigação de rotina em pacientes com câncer antes de receber a quimioterapia.
