Chronic graft-v-host disease (chronic GVHD) is a frequent cause of late morbidity and death after bone marrow transplantation (BMT). The actuarial survival after onset of chronic GVHD in 85 patients was 42% (95%Cl = 29%, 54%) at 10 years. Baseline characteristics present at the onset of chronic GVHD (before therapy) in 85 patients were reviewed to determine which were risk factors for death. In...

The morbidity and mortality associated with graft-host-disease (GVHD) is a significant obstacle to the greater use of allogeneic stem cell transplantation. Donor T cells that predominantly differentiate into TH1/Tc1 T cells and generate pro-inflammatory cytokines such as interferon-gamma (IFN-gamma) mediate GVHD. Although numerous studies have described a pathogenic role for IFN-gamma, multiple...

We investigated the effect of CD137 costimulatory blockade in the development of murine acute and chronic graft-vs-host diseases (GVHD). The administration of anti-CD137 ligand (anti-CD137L) mAb at the time of GVHD induction ameliorated the lethality of acute GVHD, but enhanced IgE and anti-dsDNA IgG autoantibody production in chronic GVHD. The anti-CD137L mAb treatment efficiently inhibited do...

Acute graft-versus-host disease (GVHD) is the most frequent, morbid complication following allogeneic hematopoietic stem cell transplantation (HSCT). Its clinical toxicity, requirement for intensive immunosup-pressive management, and associated infections lead to the greatest risks of nonrelapse mortality in HSCT recipients. In acute GVHD, donor-derived T lymphocyte-mediated alloreactivity is c...

To gain further insights in the pathogenesis of herpesvirus pneumonia in allogeneic bone marrow transplant recipients, transplanted mice (B10.BR = CBA) with graft-versus-host disease (GVHD) and control mice (transplanted mice without GVHD and normal CBA mice) were infected intranasally with herpes simplex virus type 1 (HSV-1). When compared with infected control mice, infected allogeneic transp...

Graft-versus-host disease (GvHD) is a key contributor to the morbidity and mortality after allogeneic hematopoetic stem cell transplantation (HSCT). Regulatory Foxp3(+) CD4(+) T cells (Treg) suppress conventional T cell activation and can control GvHD. In our previous work, we demonstrate that a basic mechanism of Treg mediated suppression occurs by the transfer of cyclic adenosine monophosphat...

Donor T lymphocyte transfer with hematopoietic stem cells suppresses residual tumor growth (graft-versus-tumor [GVT]) in cancer patients undergoing bone marrow transplantation (BMT). However, donor T cell reactivity to host organs causes severe and potentially lethal inflammation called graft-versus-host disease (GVHD). High-dose steroids or other immunosuppressive drugs are used to treat GVHD ...

BACKGROUND AND OBJECTIVES Graft-versus-host disease (GVHD) is a complex syndrome observed after bone marrow transplantation (BMT) affecting several organs including the lower genital female tract. We tried to evaluate the incidence of genital tract involvement and whether there are specific risk factors. DESIGN AND METHODS A retrospective study was conducted in order to describe genital manif...

BACKGROUND & OBJECTIVES This study was aimed to report the occurrence of ocular graft versus host disease (oGVHD) in allogeneic haematopoietic stem cell transplantation (allo-HSCT) patients in a tertiary care hospital setting. METHODS A cross-sectional study of ocular surface of allo-HSCT patients was done. Slit lamp biomicroscopy, symptom score, tear meniscus height, fluorescein tear break-u...
