Evaluation of the efficacy and safety of immunoadsorption or plasma exchange combined with rituximab and high-dose IVIG to reduce high titres of anti-HLA antibodies in patients prior to allogeneic haematopoietic stem cell transplantation
Full description
Approximately 10-21% of allogeneic hematopoietic stem cell transplantation (allo-HSCT) patients have non-specific or donor-specific anti-HLA antibodies (DSAs) prior to transplantation. Patients with combined DSAs and mean fluorescence intensity (MFI) ≥ 5000 can lead to a significantly higher incidence of primary graft failure and graft dysfunction after transplantation, and increased transplant-related mortality (TRM). Meanwhile, a retrospective study at our centre found that patients with high titre non-specific antibodies (MFI ≥ 5000) present before cord blood transplantation had significantly higher TRM in the early post-transplantation period. Therefore, our centre intends to conduct a single-arm prospective cohort study to explore whether the desensitisation regimen of immunosorbent or plasma exchange combined with rituximab and high-dose IVIG before transplantation in allogeneic hematopoietic stem cell transplantation patients with high titres of anti-HLA antibodies can lower the antibody titres in the patient's body, reduce the incidence of transplant-related complications, and improve the prognosis of transplantation.
