Graft-versus-host disease versus graft-versus-leukemia

Graft-versus-host disease and graft-versus-leukemia.

Allogeneic bone marrow transplantation (BMT) remains the treatment of choice for a number of malignant conditions. Much of the therapeutic potential of this procedure for these diseases relates to the graft-versusleukemia (GVL) effect, which eradicates host malignancy after BMT and is mediated by donor T and natural killer (NK) cells (1). GVL effects are closely associated, however, with graft-...

Graft Versus Host Disease

Commonly referred to as GVHD, graft-versus-host disease is a man-made condition that arises when patients are transplanted with donor tissue that is not identical to their own. Transplants from other individuals are called allogeneic (‘allo’ meaning ‘other’ and ‘geneic’ referring to ‘genes’). GVHD occurs after hematopoietic stem cell or bone marrow transplantation but is most commonly experienc...

Graft versus Host Disease

Definition Graft-versus-host disease (GVHD) is the most common complication of allogeneic hematopoietic stem cell transplantation (HSCT). In HSCT, the patient’s bone marrow is destroyed with chemotherapy and/or radiation and replaced by donor hematopoietic stem cells. In allogeneic HSCT the donor is usually a close family member or occasionally someone outside the family who has been found to b...

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...
