Non-donor specific anti-human leukocyte antigen (HLA) antibodies are not associated with poor outcome in hematopoietic stem cell transplant recipients.
Testing for anti-human leukocyte antigen (HLA) antibodies has now become standard practice in allogeneic hematopoietic stem cell transplantation (HSCT), and anti-HLA antibodies (both donor specific and non-donor specific) are being identified and have many potential consequences. Most studies suggest that donor-specific HLA antibodies lead to adverse outcomes, though little is reported on non-donor specific anti-HLA antibodies. We present the results of a retrospective cohort analysis of 157 patients who received HSCT at the University of Rochester over a period of four years. We identified 45 patients (28.7%) who had detectable anti-HLA antibodies, while only one patient (0.6%) had donor-specific anti-HLA antibodies. Patients with prior pregnancies and multiple transfusions were at increased risk to develop antibodies. In our cohort, the presence of non-donor specific anti-HLA antibodies did not significantly impact overall survival, progression free survival, graft failure, or transplant-related mortality.
