Immunization in end stage renal disease: The perception of waiting list patients

The number of patients with chronic kidney disease is increasing worldwide, as well as the number of patients in kidney transplant waiting lists. In order to prevent infections related to immunosuppressive therapy, immunization guidelines for CKD patients before transplantation have been proposed. The aim of the present study was to evaluate adherence to immunization in a cohort of CKD patients in transplant waiting list and their renal replacement therapy clinics.

CKD patients older than 18 years old, receiving renal replacement therapy longer than 12 months and included in kidney transplant waiting list at University of Campinas (Unicamp) were enrolled.

From February 2014 to December 2015, 105 patients fulfilled the inclusion criteria. Complete hepatitis B vaccination was observed in 73% and influenza vaccine in 67%. None of the other vaccine protocols reached 50% of coverage. Patients receiving immunization at primary health units presented higher coverage for diphtheria, tetanus (dT), measles, mumps, rubella (MMR), and hepatitis B vaccines, while patients immunized at renal replacement therapy clinics showed higher prevalence of pneumococcus (pneumo23).

The low rates of immunization could reflect the RRT's clinics knowledge about the vaccines guidelines and its application on daily care. We suggest an integration between transplant center and RRT clinics, through lectures, periodic checking of vaccination cards, and easy to follow guidelines in order to provide a better vaccine coverage and to obtain higher immunization rates.
