HLA Allele Distribution Associated with Adverse Drug Reactions in Organ Transplant Patients

Abstract

The results of Human Leukocyte Antigen (HLA) antigen testing in transplant patients are not generally used to predict future adverse events. In this study, free-text HLA screening results of transplant patients were analyzed and stored in a database, and the frequencies of patients with adverse events according to HLA allele were extracted. Approximately 25% of patients had HLA alleles associated with serious drug side effects.
