Factors Predicting Serum HLA Antibody Persistence or Decline in Kidney Transplant Patients

In the UK, over 8,000 patients are on the waiting list for kidney transplants. Approximately 26% of these patients are classified as highly sensitised, which significantly extends their median waiting time to around six years. The presence of HLA antibodies complicates the transplant process, as potential donors with corresponding HLA mismatches are avoided. Understanding the factors that influence the persistence or decline of HLA antibodies can aid in making informed clinical decisions and enhance the management of waiting list patients. This information is crucial for optimizing patient management and improving the chances of successful transplantation for highly sensitized patients—those with high levels of HLA antibodies who face longer waiting times and fewer compatible donor options.
