Abstract

Patients with end-stage renal disease (ESRD) and on dialysis are at increased risk of pneumococcal disease. We evaluated the immunogenicity of the 13-valent pneumococcal conjugate vaccine (PCV13) in this population. Eligible patients with ESRD and on dialysis were given a single dose of PCV13. The concentrations of serum antibodies against 13 pneumococcal capsular polysaccharides were measured at the baseline and at 2 and 12 months postvaccination. A response to the vaccine was defined as a ≥2-fold increase in antibody concentration from that at the baseline and an absolute postvaccination value of at least 1 μg/ml. Seventeen patients completed the study. Increases in the concentrations of antibodies to the vaccine serotype were demonstrated 2 months after vaccination. The geometric mean antibody concentrations at 12 months postvaccination declined by 38% to 72% compared to those measured at 2 months postvaccination. A response to at least 1 serotype in the vaccine was seen in all patients at both 2 and 12 months postvaccination. The overall rate of the response to each individual vaccine serotype varied between 23.5% and 94.1% at 2 months postvaccination and 23.5% and 65% at 12 months postvaccination. Pain at the injection site was the most common local reaction. Vaccination with PCV13 induces antibody responses to vaccine serotypes in patients with ESRD and on dialysis at 2 months postvaccination. However, the decline in antibody concentrations at 12 months postvaccination with a conjugate pneumococcal vaccine requires further study. (This study has been registered at ClinicalTrials.gov under registration no. NCT01974817.).
