Acute graft versus host disease
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...
متن کاملImmunobiology of acute graft-versus-host disease Immunobiology of acute graft-versus-host disease
Graft-versus-host disease (GVHD) has been the primary limitation to the wider application of allogeneic bone marrow transplantation (BMT). The immunobiology of acute GVHD is complex and can be conceptualized to be a three-step process. In step 1, the conditioning regimen (irradiation and/or chemotherapy) leads to the damage and activation of host tissues and induces the secretion of inflammator...
متن کاملAdvances in the treatment of acute graft-versus-host disease
Allogeneic hematopoietic stem cell transplantation (HSCT) has been widely used for the treatment of hematologic malignant and non-malignant hematologic diseases and other diseases. However, acute graft-versus-host disease (GVHD) is a life-threatening complication of allogeneic transplantation. Acute GVHD may occur in 30% of transplant recipients, which is a syndrome of erythematous skin eruptio...
متن کاملInfliximab treatment for steroid-refractory acute graft-versus-host disease.
BACKGROUND AND OBJECTIVES Tumor necrosis factor a is one of the principal cytokines involved in the pathogenesis of acute graft-versus-host-disease (GVHD). Infliximab is an antibody to this cytokine. DESIGN AND METHODS We performed a retrospective analysis to evaluate the activity of infliximab in 32 patients with severe steroid-refractory acute GVHD. The patients received a median of 3 weekl...
متن کاملAntigenaemia during acute graft versus host disease.
AIMS Animal studies have shown that antigens present within the gut play an important role in the development of acute graft versus host disease (GvHD) following allogeneic bone marrow transplantation (BMT). In previous studies, inert sugars have been found to penetrate the small bowel mucosa after conditioning therapy for BMT; endotoxaemia can also occur during acute GvHD. Data on absorption o...
