The limiting factor for successful hematopoietic stem cell transplantation (HSCT) is graft-versus-host disease (GvHD), a post-transplant disorder that results from immune-mediated attack of recipient tissue by donor T cells contained in the transplant. Mouse models of GvHD have provided important insights into the pathophysiology of this disease, which have helped to improve the success rate of...

Graft-versus-host disease (GVHD) is characterized by an impairment of mechanisms that underlie the development of immunologic tolerance. Although the cytokine storm associated with GVHD leads to expression of cell surface markers on both effector and regulatory T cells, regulatory CD4+ T cells that play an instrumental role in the maintenance of tolerance appear to uniquely express the Foxp3 tr...

Graft versus host disease (GVHD) occurs after a hematopoietic stem cell transplantation (HSCT) when the donor's immune system rejects the recipient's body, leading to significant morbidity and mortality. Increased numbers of chronic GVHD (c-GVHD) patients are likely to be seen by dental professionals because of the advances made in transplantation. The oral cavity may be the primary or the only...

This report describes a study of humoral and cellular immune reactivities in 56 patients who have survived for 1 yr to more than 6 yr after marrow transplantation from an HLA-identical sibling for the treatment of aplastic anemia or hematologic malignancy. All were conditioned for the transplant by high doses of cyclophosphamide and/or total body irradiation. Immunologic studies on the marrow d...

Acute graft-versus-host disease (GVHD) occurs after allogeneic hematopoietic stem cell transplant and is a reaction of donor immune cells against host tissues. Activated donor T cells damage host epithelial cells after an inflammatory cascade that begins with the preparative regimen. About 35%-50% of hematopoietic stem cell transplant (HSCT) recipients will develop acute GVHD. The exact risk is...

BACKGROUND Patients who have received a hematopoietic cell transplantation can develop graft-versus-host disease (GVHD). The liver, the gastrointestinal tract, and/or the skin can be affected by GVHD. Chronic sclerotic-type cutaneous GVHD can occur at sites of repetitive skin friction. PURPOSE To describe isomorphic sclerotic-type GVHD and review chronic GVHD appearing in a cutaneous immunoco...

RATIONALE Central nervous system (CNS) involvement of graft versus host disease (GvHD) is a rare cause of CNS disorders after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Chronic CNS GvHD symptoms are heterogeneous and include cerebrovascular manifestations, demyelinating disease and immune-mediated encephalitis. CNS-Acute GvHD is not formally defined in literature. PATIENT...

We evaluated demographic characteristics and graft composition as risk factors for acute graft-versus-host disease (GVHD) in 160 adult recipients of HLA-identical allogeneic blood stem cell transplants. The patients received a median nucleated cell dose of 7.9 3 108/kg and median C341 cell dose of 5.6 3 106/kg. GVHD prophylaxis consisted of cyclosporine (CSA) and steroids, tacrolimus (FK506) an...

Although graft-versus-host disease (GVHD) is a life-threatening complication of hematopoietic stem-cell transplantation (HSCT), its current diagnosis depends mainly on clinical manifestations and invasive biopsies. Specific biomarkers for GVHD would facilitate early and accurate recognition of this grave condition. Using proteomics, we screened for plasma proteins specific for GVHD in a mouse m...

This study was conducted to elucidate the influence of immunosuppressive treatment (IST) and GVHD on risk of recurrent malignancy after allogeneic hematopoietic cell transplantation (HCT). The study cohort included 2656 patients who received allogeneic HCT after high-intensity conditioning regimens for treatment of hematologic malignancies. Rates and hazard ratios of relapse and mortality were ...
