ABSTRACT
Abstract

Introduction:

Bacterial or viral diseases are one of the major causes of death in patients with chronic kidney disease (CKD). These patients show a quantitative reduction of levels of antibodies over time. Among the infectious diseases that affect CKD patients, stands out hepatitis B (HB). Immunization and control of antibodies levels against the hepatitis B surface antigen (anti-HBs) are ways to prevent the HB infection in this population. Patients with anti-HBs levels ≥10 IU/ml are considered adequate responders, whereas those with anti-HBs levels ≥ 100 IU/ml are considered excellent responders.

Objective:

To analyze the variation of the anti-HBs levels obtained after vaccination against HB in children and adolescents in the pre-dialysis stage of CKD.

Methods:

A retrospective cohort study on anti-HBs levels of children and adolescents in the pre-dialysis stage of CKD. Correlation between levels of anti-HBs titers and time since the vaccination were estimated.

Results:

From the total of 116 studied patients most of the studied patients were considered excellent responders, obtaining in the three anti-HBs titers percentages of 70.7%, 62.1% and 54.9% respectively. The anti-HBs titer levels showed a negative correlation with the time since vaccination (Kendall Tau-b = -0.16; p = 0.02).

Conclusion:

The majority of the studied population was vaccinated by PNI and showed excellent anti-HBs titer levels, even experiencing a progressive reduced response over the time.
RESUMO
Resumo

Introdução:

As doenças infecciosas, bacterianas ou virais, são uma das principais causas de morte dos pacientes com doença renal crônica (DRC), que apresentam um decréscimo na duração da imunidade em comparação às pessoas saudáveis. Entre as doenças infecciosas que acometem os portadores de DRC, destaca-se a hepatite B (HB). A imunização e o controle dos níveis de anticorpos contra o antígeno da superfície da hepatite B (anti-HBs) são formas de evitar a contaminação da HB nessa população. Pacientes com o nível de anti-HBs ≥ 10 UI/ml são considerados adequados respondedores, enquanto aqueles com níveis de anti-HBs ≥ 100 UI/ml são considerados excelentes respondedores.

Objetivo:

Analisar a variação dos níveis de anti-HBs adquiridos após a vacinação contra a HB em crianças e adolescentes na fase pré-dialítica da DRC.

Métodos:

Estudo de coorte retrospectivo dos níveis de anti-HBs de crianças e adolescentes na fase pré-dialítica da DRC.

Resultados:

Dos 116 pacientes do estudo, a maior parte foi considerada respondedores excelentes, obtendo nas três titulagens percentuais de 70,7%, 62,1% e 54,9%, respectivamente. Os níveis de anti-HBs apresentaram uma correlação negativa com o tempo de vacinação (Kendall Tau-b = - 0,16; p = 0,02).

Conclusão:

Conclui-se que a maior parte da população do estudo apresenta níveis de anti-HBs excelentes, ocorrendo uma queda progressiva da titulagem ao longo do tempo.
