Acute graft-versus-host disease (aGVHD) remains one of the most severe complications in organ and bone marrow transplantation, leading to much morbidity and mortality. Obesity has been associated with increased risk of development of various inflammatory diseases. Here, we investigated the in vitro and in vivo effects of obese donor splenocytes on the development of acute graft-versus-host dise...

For circulating lymphocytes to migrate to inflammatory sites, they must first adhere to the target tissue endothelium with sufficient strength to overcome the shear forces of blood flow. We previously reported that dermal papillary vessels in acute graft-versus-host disease (aGVHD) support shear-resistant lymphocyte adherence. We now identify the relevant adhesion molecule(s) directing this bin...

Steroid refractory gastrointestinal (GI) acute graft-versus-host disease (aGVHD) is a major cause of mortality in hematopoietic stem cell transplantation (HCT) without immune markers to establish a diagnosis or guide therapy. We found that T-cell receptor β (TCRβ) complementarity-determining region 3 repertoire sequencing reveals patterns that could eventually serve as a disease biomarker of T-...

Acute graft-versus-host disease (aGVHD) is a frequent and at times unpredictably severe inflammatory complication of allogeneic hematopoietic cell transplantation (HCT). Despite over 5 decades of extensive laboratory and clinical investigation into methods to prevent severe aGVHD, this complication remains a significant cause of morbidity and mortality in allogeneic HCT recipients. Each year, ;...

Acute GVHD (aGVHD) remains a major source of morbidity after allogeneic hematopoietic cell transplantation. CD30 is a cell-surface protein expressed on certain activated T cells. We analyzed CD30 expression on peripheral blood T-cell subsets and soluble CD30 levels in 26 patients at the time of presentation of aGVHD, before the initiation of treatment, compared with 27 patients after hematopoie...

Narrowband ultraviolet B (NB-UVB) has been widely used in dermatological phototherapy. As for the application of NB-UVB phototherapy to graft-versus-host disease (GVHD), we previously reported that it was highly efficacious for cutaneous lesions of acute GVHD (aGVHD) and that expansion of regulatory T (Treg) cells induced by NB-UVB might be one of the mechanisms. In order to examine whether NB-...

Acute graft-versus-host disease (aGVHD) remains a clinical challenge and a major source of morbidity and mortality following allogeneic hematopoietic stem cell transplantation (allo-HSCT). Dimethyl fumarate (DMF), an activator of Nrf2, has been shown to have anti-inflammatory and immunomodulatory properties without significant immunosuppression. We therefore hypothesized that DMF could be poten...

Abstract Acute graft-versus-host disease (aGvHD) is a severe, often lethal, complication of hematopoietic stem cell transplantation, and although prophylactic regimens are given as standard pretransplantation therapy, up to 60% these patients develop aGvHD, require additional immunosuppressive intervention. We treated mice with purified probiotic molecule, exopolysaccharide (EPS) from Bacillus ...

BACKGROUND The prognostic value of the NIH consensus criteria for graft-versus-host disease (GVHD) is not well defined yet. PATIENTS AND METHODS We analyzed NIH-defined GVHD in 147 acute lymphoblastic leukemia (ALL) patients. RESULTS The cumulative incidence of classic acute GVHD (aGVHD), late aGVHD and chronic GVHD (cGVHD) was 63%, 12% and 41%, respectively. cGVHD was subclassified as clas...

Risk factors for acute GVHD (AGVHD), overall survival, and transplant-related mortality were evaluated in adults receiving allogeneic hematopoietic cell transplants (1999-2005) from HLA-identical sibling donors (SDs; n = 3191) or unrelated donors (URDs; n = 2370) and reported to the Center for International Blood and Marrow Transplant Research, Minneapolis, MN. To understand the impact of trans...
