Allogeneic hematopoietic cell transplantation (HCT) is an effective treatment for adult T-cell leukemia (ATL), raising the question about the role of graft-versus-leukemia effect against ATL. In this study, we retrospectively analyzed the effects of acute and chronic graft-versus-host disease (GVHD) on overall survival, disease-associated mortality, and treatment-related mortality among 294 ATL...
Corticosteroids are the accepted primary therapy for acute graft-versus-host disease (GVHD), but durable responses are seen in only about half of the patients. Blood and Marrow Transplant Clinical Trials Network (BMT CTN) 0802, a phase 3 multicenter randomized double-blinded trial, was designed to test whether mycophenolate mofetil (MMF) plus corticosteroids was superior to corticosteroids alon...
While increased numbers of eosinophils may be detected in patients with graft-versus-host disease (GVHD) following hematopoietic stem cell transplantation, it is not known if eosinophils play a role in GVHD. The aims of this study were to determine: whether eosinophils are activated during GVHD; whether the patterns of activation are similar in acute and chronic GVHD; and the ways in which syst...
Graft-versus-host disease (GVHD) is still one of the major causes of morbidity and mortality in allogeneic hematopoietic stem cell transplantation (HSCT). In the pathogenesis of acute GVHD, it has been established that donor-derived T-cells activated in the recipient play a major role in GVHD in initiation and maintenance within an inflammatory cascade. To reduce the risk of GVHD, intensificati...
We have demonstrated that a single injection of interleukin (IL)-12 on the day of bone marrow transplantation (BMT) inhibits acute graft-versus-host disease (GVHD) in mice. This effect of IL-12 can be diminished by anti-interferon (IFN)-gamma mAb. To determine the mechanism by which IFN-gamma affects IL-12-mediated GVHD protection, we have compared the effect of IL-12 on GVHD in C57BL/6 wild-ty...
Kinetics of IFN-γ and IL-17 Production by CD4 and CD8 T Cells during Acute Graft-versus-Host Disease
Graft-versus-host disease (GVHD) is a fatal complication that occurs after allogeneic hematopoietic stem cell transplantation. To understand the dynamics of CD4 and CD8 T cell production of IFN-γ and IL-17 during GVHD progression, we established a GVHD model by transplanting T cell-depleted bone marrow (TCD-BM) and purified T cells from B6 mice into irradiated BALB.B, creating an MHC-matched bu...
Myeloid-derived suppressor cells (MDSCs) inhibit T-cell expansion and functions by versatile mechanisms such as nutrient depletion, nitrosylation, or apoptosis. Since graft-versus-host disease (GVHD) is characterized by the expansion of donor-derived T cells destroying recipient tissue, we analyzed whether MDSCs can be used for GVHD prevention in murine allogeneic bone marrow transplantation mo...
Acute graft-versus-host disease (GVHD) is a common complication of allogeneic hematopoietic stem cell transplantation (HSCT). It has been proposed that tumor necrosis factor alpha (TNF-alpha) blockade with infliximab may be an effective treatment for severe (grades III-IV) GVHD. We determined if infliximab use in this high-risk population was associated with an additional increased risk of non-...
Kinetics of bilirubin and liver enzymes is useful for predicting of liver graft-versus-host disease.
Graft-versus-host disease (GVHD) is the most frequent complication after allogeneic hematopoietic cell transplantation. We analyzed the kinetics of bilirubin and liver enzymes in 47 cases with liver GVHD and in 47 cases without GVHD after allogeneic transplantation for various hematological malignancies. The duration of an liver GVHD episode (LGVHD) was defined as the interval from the point wh...
Mesenchymal stromal cells (MSCs) have been reported to have immunomodulatory effects and ameliorate severe graft-versus-host disease (GVHD) after allogeneic stem cell transplantation (SCT). We have conducted a pilot study using human MSCs for the treatment of steroid-resistant GVHD. Between January 2006 and December 2010, 10 patients (7 males and 3 females) with a median age of 37.9 years (rang...
