Resumo: | Introduction: Seroconversion to the vaccine against hepatitis B virus (HBV) in immunocompetent individuals ranges from 90-95% while in hemodialysis patients varies from 40-80%. The maintenance of adequate levels of antibodies against HBV in the dialysis units is an important strategy for reducing the risk of HBV transmission and of incidence of chronic complications of hepatitis B. Objectives: To evaluate the factors influencing seroconversion of antibody anti-HbS in patients vaccinated against HBV in different stages of chronic kidney disease (CKD) and treated by hemodialysis (HD) or peritoneal dialysis (PD). Patients and Methods: We included patients greater than 18 years, patients with CKD prevalent in December 2011 and 2012 incidents between January and April 2014, who received the first full vaccination scheme against HBV. The patients were divided into four groups according to the stage of CKD and dialysis modality: DRC Group (patients in stage IV of the CKD), Pre-dialysis group (patients in stage V of the CKD), HD group (patients treated by HD), and PD Group (patients treated by PD). Associations between demographic, clinical, laboratory, dialytic, and nutritional factors with seroconversion to the vaccine against HBV (antibody anti-HBS > 10 IU/dl) were analyzed by univariate and multivariate logistic regression. Results: A total of 191 patients were included; 72 in the HD, 40 at DP, 36 in the DRC, and 43 in the Pre dialysis group). The average age was 59.6 ± 15.1 years; 49.7% were male, 83.5% of the white race and 47.6% diabetics. The overall percentage of seroconversion was 72.8%; 76.4% for the HD, 67.5% for DP, 75% for the DRC and 69.8% for Pre dialysis group (p = 0.72). The factors independently associated with the greater chance of seroconversion were the total lymphocyte count (p = 0.02) and the phase angle (p = 0.02), considering the total sample of patients; the total lymphocyte count (p = 0.033) and the use of vitamin D ... |
