AbstractObjectivesWe retrospectively compared the prophylactic effect of basiliximab and antithymocyte globulin (ATG) after haploidentical hematopoietic stem cell transplantation (HSCT) in patients with leukemia.MethodsHaploidentical HSCT using basiliximab for graft-versus-host disease (GVHD) prophylaxis in 10 patients with leukemia was retrospectively compared to ATG for GVHD prophylaxis in 24 patients.ResultsAll the patients achieved neutrophil engraftment. One patient in the ATG group did not achieve platelet engraftment. The incidence of grade II–IV and grade III–IV acute GVHD was 30 and 20%, respectively, in the basiliximab group and 16.7 and 4.2%, respectively, in the ATG group (P > 0.05). Extensive cGVHD developed in 40 and 22.2% of patients in the basiliximab group and ATG group, respectively (P > 0.05). Basiliximab resulted in mild infection and a low incidence (10%) of infection-related mortality; ATG resulted in relative severe infection with 29.2% infection-related mortality (P > 0.05). During the follow-up period, 20% of the basiliximab group and 22.7% of the ATG group relapsed (P > 0.05). In the basiliximab group and the ATG group, the 3-year accumulative overall survival rate was, respectively, 80 and 52.5% and the 3-year leukemia-free survival, respectively, was 60 and 49.6% (P > 0.05).DiscussionThe incidences of grade II–IV and grade III–IV aGVHD in the basiliximab group were similar to those in halpoidentical HSCT containing ATG. Compared to the ATG group, the basiliximab group had a lower rate of transplantation-related mortality and better long-term survival, but without statistical significance.ConclusionThe prophylactic regimen of basiliximab with haploidentical HSCT against GVHD seems safe and promising. More studies needed to verify this. 相似文献

Sickle cell disease (SCD) is an inherited disorder; despite significant improvements in supportive care, SCD continues to cause substantial morbidity, mortality, and reduced life expectancy. Allogeneic hematopoietic stem cell transplantation (HSCT) is currently the only widely available curative therapy for SCD, which is offered as a standard of care for patients with a matched sibling donor (MSD). Donor availability is limited to a minority of patients. Thus, αβ/CD3-depleted haploidentical HSCT, as an efficient means for depletion of graft-versus-host disease (GvHD)-mediating T cells, can be offered as an alternative curative therapy, particularly for nonmalignant diseases such as SCD.Out of 38 patients with advanced stage SCD, 25 were transplanted with CD3/CD19- or T-cell receptor αβ/CD19 T-cell-depleted peripheral stem cell grafts (T-haplo-HSCT group), whereas 13 transplanted from MSD (MSD group); both groups received an almost identical conditioning regimen. Engraftment was achieved in all. However, in the T-haplo-HSCT group, three patients succumbed to an uncontrolled cytomegalovirus pneumonitis, a macrophage activation syndrome, and a major blood group incompatibility with a late graft failure and multiorgan failure. The overall survival was 88% and 100% in T-haplo-HSCT and MSD groups, respectively. None of our patients developed a Glucksberg Grade III–IV acute GvHD. Four patients (16%) in the T-haplo-HSCT group and two patients (15%) in the MSD group developed a steroid-sensitive, mild-to-moderate chronic GvHD that resolved within 18 months posttransplant.These results are encouraging and demonstrate the feasibility, safety, and efficacy of T-haplo-HSCT in advanced stage SCD in children and adults, thus offering a curative alternative to majority of patients. 相似文献

IL-2 activated NK cell immunotherapy of three children after haploidentical stem cell transplantation 总被引:5,自引:0,他引:5

Natural killer (NK) cells are thought to be of benefit in HLA-mismatched hematopoietic transplantation (H-SCT). Therefore, we developed a protocol for clinical-use expansion of highly enriched and IL-2-stimulated NK cells. Purification of unstimulated leukaphereses by a two-step T cell depletion with a final CD56 enrichment procedure leads to a mean purity of 95% CD56(+)CD3- NK cells with a four- to five-log depletion of T cells. So far, three pediatric patients with multiply relapsed acute lymphoblastic leukemia (ALL) or acute myelogenous leukemia (AML) were treated with repeated transfusions post-H-SCT. Directed killer immunoglobulin-like receptor (KIR) mismatches were demonstrated in all three cases. Although all patients showed blast persistence at the time of transplant, they reached complete remission and complete donor chimerism within 1 month post-H-SCT. NK cell therapy was tolerated well without graft-versus-host disease (GvHD) induction or other adverse events. The AML patient died of early relapse on day +80, while the ALL patients died of thrombotic-thrombocytopenic purpura and atypical viral pneumonia on days +45 and +152, respectively. This initial trial showed the feasibility of good manufacturing practice (GMP)-compliant NK cell isolation and expansion for clinical applications. We now launch a clinical phase I trial with activated NK cells post-H-SCT. 相似文献
