Postremission therapy in patients with acute myeloid leukemia (AML) may consist of continuing chemotherapy or transplantation using either autologous or allogeneic stem cells. Patients with favorable subtypes of AML generally receive chemotherapeutic consolidation, although recent studies have also suggested favorable outcome after hematopoietic stem cell transplantation (HSCT). Although alloge...

Allogeneic hematopoietic stem cell transplantation is an established treatment modality for malignant and nonmalignant hematologic diseases. Acute and chronic graft-versus-host diseases (GVHDs) are a major cause of morbidity and mortality after allogeneic stem cell transplantation. T cells have been identified as key players in the graft-versus-host reaction and, therefore, most established dru...

The CD30-targeted agent brentuximab vedotin has shown impressive activity in relapsed/refractory Hodgkin lymphoma and anaplastic large cell lymphoma in phase II studies. We have treated 24 patients with relapsed/refractory disease enrolled onto a Named Patient Programme during 2010-11 at a single UK center. Overall response rate across all histologies was 67% (Hodgkin 72%; anaplastic large cell...

Human herpesvirus 6 (HHV-6) infection was studied in 82 bone marrow transplant (BMT) recipients (72 allogeneic, 10 autologous). All recipients and 30 donors were seropositive for HHV-6 antibody at the time of bone marrow transplantation. Thirty-one recipients (37.8%) had HHV-6 viremia 2-4 weeks after transplantation. The incidence of HHV-6 viremia was significantly higher among allogeneic BMT r...

Allogeneic transplants with PBSC are rapidly expanding, but a number of problems concerning both donors and recipients are still unsolved. GITMO (Italian Bone Marrow Transplant Group) has established a committee for allogeneic PBSC transplants. We present here an analysis of the main aspects of this evolving area and suggest revised guidelines for the use of allogeneic PBSC transplantation.

Delayed recovery of platelet count post allogeneic hematopoietic stem cell transplantation (allo-HSCT) has been associated with worse transplant outcomes. Thrombopoietic agents have been successfully used in immune mediated thrombocytopenia or thrombocytopenia from bone marrow failure syndromes; however, the experience regarding their use after allo-HSCT is limited. Here we report on the safety...

Bone marrow transplantation has become the accepted treatment for several hematologic disorders. We have done 3 autologous and 6 allogeneic bone marrow transplantations at Ramathibodi Hospital since July 1989 in patients with acute lymphoblastic leukemia, acute non-lymphocytic leukemia, chronic myeloid leukemia, non-Hodgkin's lymphoma and severe aplastic anemia. Only one patient with aplastic a...

Background: Mesenchymal stem cells (MSCs) are considered as effective therapeutic cells in transplantation due to their immunomodulatory activities. However, precise mechanism of MSCs immunomodulatory activity is not completely understood. Objectives: To study the role of Immunoglobulin-like transcripts-3 (ILT3) immunomodulatory receptor in immune tolerance induced by MSCs in skin transpla...

The subpopulation of regulatory T cells (Treg) was shown to play a key role in alloreactive responses. In allogeneic hematopoietic stem cell transplantation, several groups tested whether Treg content in transplants correlates with graft-versus-host disease (GVHD) with controversial results. In a retrospective study of 49 consecutive HLA-matched sibling transplantations, we studied the relation...

Mycosis Fungoides is typically an indolent disease in early stages. However, approximately 30% of patients have advanced staged disease at presentation and 20% will develop it at some time. These patients have a poorer prognosis with a median survival of 2-4 years. The only curative option for mycosis fungoides may be hematopoietic allogeneic stem cell transplantation. We report the case of a p...
