This study reviews patients who received haploidentical hematopoietic stem cell transplantation (haplo-HSCT). Some patients develop donor-specific antibodies (DSA), which can block engraftment and cause transplant failure. Before transplant, a treatment called protein A immunoadsorption (a blood purification method to remove antibodies) was used, sometimes with additional medications. The study aims to see whether this approach lowers antibody levels, increases the chance of successful engraftment, reduces complications such as infections or graft failure, and improves short-term survival. The results may help guide safer and more effective transplants for highly sensitized patients.
