Abstract Recent experience suggests that reduced-intensity conditioning (RIC) regimens can improve the outcomes of patients with hemophagocytic lymphohistiocytosis (HLH) undergoing allogeneic hematopoietic cell transplantation (HCT). However, studies directly comparing RIC to myeloablative conditioning (MAC) regimens are lacking. Forty patients with HLH underwent allogeneic HCT between 2003-2009 at Cincinnati Children's Hospital. Fourteen patients received MAC consisting of busulfan, cyclophosphamide, and antithymocyte globulin plus or minus etoposide. Twenty-six patients received RIC consisting of fludarabine, melphalan, and alemtuzumab. All patients engrafted. Acute graft-versus-host disease grades II to III occurred in 14% of MAC patients and 8% of RIC patients (P = .3171). Posttransplantation mixed donor/recipient chimerism developed in 18% of MAC patients and 65% of RIC patients (P = .0110). The majority of patients with mixed chimerism received intervention with reduction of immune suppression plus or minus donor lymphocyte infusion or stem cell boost, which stabilized or increased donor contribution to hematopoiesis and prevented relapse of HLH in all but 1 patient. Grade II to III graft-versus-host disease occurred in 5 of 14 RIC patients after donor lymphocyte infusion. The overall estimated 3-year survival after HCT was 43% (confidence interval = ± 26%) for MAC patients and 92% (confidence interval = ± 11%) for RIC patients (P = .0001). We conclude that RIC significantly improves the outcome of patients with HLH undergoing allogeneic HCT.

Reduced Intensity

Allogeneic hematopoietic cell transplantation (allo-HCT) preconditioning intensity, donor choice, and graft-versus-host disease (GVHD) prophylaxis for advanced myelofibrosis (MF) have not been fully elucidated. Thirty-five patients with advanced MF were treated with reduced-intensity conditioning (RIC) allo-HCT. We searched for matched sibling (n=16) followed by matched (n=10) or mismatched (n=5) unrelated and familial mismatched donors (n=4). Preconditioning regimen consisted of fludarabine (total 150 mg/m2) and busulfan (total 6.4 mg/kg) with total body irradiation≤ 400cGy. All showed engraftments, but four (11.4%) showed either leukemic relapse (n=3) or delayed graft failure (n=1). Two-year overall survival (OS) and non-relapse mortality (NRM) was 60.0% and 29.9%, respectively. Acute GVHD was observed in 19 patients, and grade III-IV acute GVHD was higher with HLA-mismatch (70% vs. 20%, p=0.008). Significant hepatic GVHD was observed in nine patients (5 acute, 4 chronic), and six of them died. Multivariate analysis revealed inferior OS with HLA-mismatch (HR=6.40, 95%CI 1.6-25.7, p=0.009) and in patients with high ferritin level at post-HCT D+21 (HR=7.22, 95%CI 1.9-27.5, p=0.004), which were related to hepatic GVHD and high NRM. RIC allo-HCT can be a valid choice for advanced MF. However, HLA-mismatch and high post-HCT ferritin levels related to significant hepatic GVHD should be regarded as poor-risk parameters.
