ABSTRACT

Abstract Introduction: Vaccination is the most effective tool in preventing transmission of Hepatitis B Virus (HBV). The patient with chronic kidney disease (CKD) on dialysis appear to be at greater risk of becoming infected with this virus and does not show the same vaccine response when compared to patients without uremia. Objectives: To evaluate the results related to the HBV vaccine and identify factors associated with the response in patients with CKD on hemodialysis. Methods: Individuals with HBsAG and negative anti-HBC, under hemodialysis were assessed in two units of São Luis, Maranhão and were undergone full vaccination schedule for HBV. They were divided in groups: anti-HBs10 mUI/mL and compared as to age, gender, presence of diabetes mellitus (DM), time on dialysis and anti-HCV status. Logistic regression analysis was performed to identify factors independently associated with the vaccine response. p10mUI/Ml (or = 5.239 IC: 1.279-21.459, p = 0.021). Conclusion: The rate of vaccine response to HBV in patients with CKD on dialysis was 70% and the lack of anti-HCV infection was associated with seroconversion of anti-HBs suggesting that infection by the hepatitis C virus may be a factor that decreases the response of the HBV vaccine in dialysis CKD patients.


Resumo Introdução: A vacinação é a medida mais efetiva na prevenção da transmissão do vírus da hepatite B (HBV). O portador de doença renal crônica (DRC) em diálise apresenta maior risco de se contaminar com este vírus e não tem a mesma resposta vacinal quando comparada com indivíduos sem uremia. Objetivos: Avaliar os resultados da vacina para o HBV e identificar fatores associados à resposta, em portadores de DRC em hemodiálise. Metodologia: Foram avaliados indivíduos com HBsAg e anti-HBc negativos, que estavam sob hemodiálise em duas unidades de São Luís, Maranhão e que haviam sido submetidos ao esquema completo de vacinação para o HBV. Foram distribuídos em dois grupos: anti-HBs < 10mUI/mL e anti-HBs ≥ 10mUI/mL e comparados quanto à idade, gênero, presença de diabetes mellitus (DM), tempo em diálise e status do anti-HCV. Análise de regressão logística foi realizada para identificar fatores independentemente associados à resposta vacinal. Anti-HBs ≥ 10mUI/mL(OR = 5.239 IC:1.279-21.459, p = 0.021) Conclusões: A taxa de resposta vacinal ao HBV em portadores de DRC em diálise foi de 70% e a ausência do anti-HCV foi associada à soroconversão do anti-HBs, sugerindo que a infecção pelo vírus da hepatite C pode ser um fator que diminui a resposta da vacina para o HBV em indivíduos portadores de DRC em diálise.
