Human leukocyte antigen immunization in transfusion-dependent Moroccan patients with beta-thalassemia major: prevalence and risk factors.

Introduction: Beta-thalassemia major patients need a regular blood transfusion to have an initial normal growth. However, these patients have an increased risk of developing alloantibodies. Our main goal was to study HLA alloimmunization in Moroccan Beta-thalassemia patients by confronting it with transfusion and demographic criteria, exploring the involvement of HLA typing profile in the development of HLA antibodies and in turn determining risk factors for their development.

Renal transplantation is the best therapeutic approach for end-stage kidney disease. Renal transplantation can be performed using living donors or brain-dead donors. Vaccination in recipients poses a real problem with the transplantation process because it is responsible for particular difficulties in choosing a donor and above all exposes to the risk of transplant rejection.
