Insights
Pediatric kidney transplant patients in Brazil have poor vaccination coverage. Most children lack essential vaccines before and after transplantation, highlighting missed opportunities for immunization.
Area of Science:
- Pediatric Nephrology
- Immunology
- Transplantation
Background:
- Pediatric renal transplant recipients require specific vaccination protocols due to their immunocompromised state.
- Inadequate immunization increases the risk of vaccine-preventable diseases in this vulnerable population.
Purpose of the Study:
- To evaluate the immunization status of pediatric patients undergoing renal transplantation.
- To identify gaps in vaccination coverage before and after transplantation.
Main Methods:
- Retrospective analysis of vaccination charts for 46 pediatric patients (aged 1-18 years).
- Assessment of immunization according to the Brazilian National Immunization Program and Special Immunobiological Agents Program.
- Evaluation of vaccination status pre- and post-kidney transplantation.
Main Results:
- Only 4.3% of patients had up-to-date vaccination records pre- and post-transplant.
- While routine vaccines were often administered, special vaccines for immunocompromised children were frequently missed.
- A significant proportion of patients (62.2% pre-transplant, 52.1% post-transplant) received only routine vaccines, not specialized ones.
Conclusions:
- Pediatric renal transplant patients in Brazil exhibit incomplete immunization status.
- Missed vaccination opportunities and apprehension contribute to suboptimal immunization coverage.
- Improved vaccination strategies are crucial, particularly before kidney transplantation, for children with kidney diseases.
Abstract:
To assess the immunization status of pediatric renal transplant patients followed at a single center in Brazil, vaccination charts of all patients aged between one and 18 yr were analyzed both pre- and post-transplantation. Appropriate immunization was defined according to the National Immunization Program (routine vaccines) - for all Brazilian children - and the Special Immunobiological Agents Program that also includes special vaccines for immunodeficient or other high-risk children. A total of 46 patients was evaluated (mean age 13.7 yr; range 4-17 yr). Vaccination charts were found to be up to date in only two patients (4.3%) pretransplant and in two (4.3%) post-transplant. Although 36 patients (62.2%) in the pretransplant phase and 24 (52.1%) in the post-transplant phase had been vaccinated according to the National Immunization Program, they had not received the special vaccines indicated for their immunocompromised condition. Therefore, despite being followed at a referral center, almost all patients presented an incomplete immunization status pre- and post-transplant. This probably reflects missed opportunities and medical/parental apprehension related to vaccination of patients with chronic renal insufficiency, dialysis or kidney transplantation. Efforts should be made to ensure adequate vaccination in children with kidney diseases, especially before kidney transplantation.
