BACKGROUND Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening hyperinflammatory syndrome that remains difficult to treat. Even with current standard HLH therapy, only approximately half of patients will experience complete resolution of disease, and early mortality remains a significant problem. Salvage therapies have been described only in(More)
Matched sibling donor (MSD) bone marrow transplantation is the treatment of choice for pediatric patients with severe aplastic anemia (SAA); however, only about 33% of patients will have an HLA-identical sibling. Alternative donor (AD) transplants may be an option for these patients, but such therapies have been associated with greater incidence of graft(More)
In 87 patients with aplastic anemia who failed to respond to immunosuppressive treatment, we determined the minimal dose of total body irradiation (TBI) required when added to antithymocyte globulin (ATG, 30 mg/kg x 3) plus cyclophosphamide (CY, 50 mg/kg x 4) to achieve engraftment of unrelated donor marrow. TBI was started at 3 x 200 cGy, to be escalated(More)
BACKGROUND Randomized trials have shown that the transplantation of filgrastim-mobilized peripheral-blood stem cells from HLA-identical siblings accelerates engraftment but increases the risks of acute and chronic graft-versus-host disease (GVHD), as compared with the transplantation of bone marrow. Some studies have also shown that peripheral-blood stem(More)
A prospective multicenter trial was conducted to evaluate the safety and feasibility of granulocyte colony-stimulating factor (G-CSF)-primed bone marrow (G-BM) in children receiving allogeneic bone marrow transplantation (BMT). A total of 42 children with a median age of 9.8 years (range, 0.8-17 years) were enrolled. Donors with median age of 9.2 years(More)
Given the rarity of follicular lymphoma (FL) in children, there is limited data on which to base treatment recommendations. Herein, we report our institutional experience of using rituximab with multiagent chemotherapy for pediatric FL. Six pediatric patients were diagnosed with FL from 2000 to 2009. All patients received rituximab in combination with(More)
Guillain-Barré syndrome is a rare complication in the setting of hematopoietic stem cell transplantation. We report three children with T cell lymphoma/leukemia in whom this syndrome developed soon after they received unrelated donor transplants. The rapid onset of symptoms raises the concern that the bone marrow transplant conditioning regimen (ie, total(More)
Patients with Fanconi anemia (FA) commonly develop bone marrow failure, which may evolve to myelodysplasia or acute myeloid leukemia (AML). Treatment of these patients is complicated by their marked hypersensitivity to DNA cross-linking agents. In this report we describe the results of allogeneic unrelated donor bone marrow transplantation in seven FA(More)
Infliximab-daclizumab was used to treat acute and chronic liver and gut graft-versus-host disease (GVHD) in two children after standard immunosuppressive therapy failed. Infliximab (10 mg/kg weekly, 4 doses) and daclizumab (1 mg/kg, days 1, 4, 8, 15, and 22) were given over 1 month. In case 1, grade 2 chronic GVHD of the liver developed 1 year after(More)
