Microbial metabolites and graft versus host disease

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...

Relationship between Molecular Chimerism and Graft Versus Host Disease after Allogenic Hematopoietic Stem Cell Transplantation

Background: Bone marrow transplantation (BMT) is considered as a curative therapy for a broad range of diseases. However, complications such as relapse and graft versus host disease (GVHD) may be observed following BMT. Chimerism analysis serves as a reliable indicator of transplant outcome. Complete chimerism refers to the complete replacement of hematopoietic system by donor cells, while mixe...

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-...
