Abstract
PURPOSE: Since children referred for orthotopic liver transplantation (OLT) in Switzerland were not vaccinated optimally, new guidelines were set up and recommended to base catch-up immunization on serum antibody titers against vaccinepreventable diseases, before and after OLT.
METHOD: We measure the results of this serology-based intervention by comparing vaccine coverage and antibody titers in the pre- (1990-2002, P1) and post-intervention (2003-2008, P2) cohorts. Antibodies are measured by ELISA.
RESULTS: 44 P1 and 30 P2 children were evaluated. At pre-OLT visit, diphtheria (D), tetanus (T), S. pneumoniae (SPn) and measles-mumps-rubella (MMR) serologies were checked more frequently in P2 than P1 (P<0.05). More P2 children were up-todate for diphtheria-tetanus-pertussis (DTaP) and MMR (P<0.05) or had received ≥1 dose of hepatitis B (HBV), hepatitis A (HAV), SPn and varicella-zoster virus (VZV) vaccines (P<0.05). One year post-OLT, DT, SPn, MMR and VZV serologies were more frequently checked (P<0.05) and antibody titers were higher for DT and HAV (P<0.05) in P2. Gender, age or diagnosis didn't explain these differences. Among P2 patients, pre- and post-OLT titers for D, T, Haemophilus influenzae type b (Hib), HBV, SPn14 and SPn19 were correlated (P<0.05 for all).
CONCLUSION: Protection against vaccine-preventable diseases of high-risk children like OLT patients can be significantly improved by serology-based intervention for vaccine-preventable diseases
