We evaluated demographic characteristics and graft composition as risk factors for acute graft-versus-host disease (GVHD) in 160 adult recipients of HLA-identical allogeneic blood stem cell transplants. The patients received a median nucleated cell dose of 7.9 3 108/kg and median C341 cell dose of 5.6 3 106/kg. GVHD prophylaxis consisted of cyclosporine (CSA) and steroids, tacrolimus (FK506) an...

Results of a previous study suggested that recipient mismatching for the minor histocompatibility antigen HA-1 is associated with acute graft-versus-host disease (GVHD) after allogeneic marrow transplantation. In that study, most patients received either cyclosporine or methotrexate for GVHD prophylaxis, and a cytotoxic T-cell clone was used to test for HA-1 disparity. To facilitate large-scale...

BACKGROUND Graft-versus-host disease (GvHD) is a major challenge after hematopoietic stem cell transplantation but treatment options for patients are still limited. In many cases first-line treatment with glucocorticoids is not successful. Among second-line therapies the extracorporeal photopheresis (ECP) is frequently performed, due to induction of selective tolerance instead of general immuno...

engraftment by donor lymphocytes in an immunologically compromised host can result in donor t-cell activation against host major histocompatibility complex antigens, with resultant gvhd. the acute form of gvhd (agvhd) is characterized by erythroderma, cholestatic hepatitis, and enteritis. the intestinal symptoms of agvhd include crampy abdominal pain and watery diarrhea, often with blood. the c...

RATIONALE Central nervous system (CNS) involvement of graft versus host disease (GvHD) is a rare cause of CNS disorders after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Chronic CNS GvHD symptoms are heterogeneous and include cerebrovascular manifestations, demyelinating disease and immune-mediated encephalitis. CNS-Acute GvHD is not formally defined in literature. PATIENT...

During the past decade, progress in basic immunology has been impressive. In parallel, whereas our understanding of the pathophysiology of acute graft-versus-host disease (GVHD) has greatly improved, so has our knowledge of the complexities of the immune system. Much of the immunobiology of acute GVHD has been gleaned from preclinical models and far less from correlations with clinical observat...

BACKGROUND Results of a previous study with human leukocyte antigen (HLA)-identical siblings showed individual and synergistic associations of single nucleotide polymorphisms in the promoter region of the recipient's IL10 gene and the donor's IL10 receptor beta (IL-10RB) gene with development of grades III-IV acute graft-versus-host disease (GVHD) after allogeneic hematopoietic cell transplanta...

Oral graft-versus-host disease (GVHD) and oral mucositis (OM) are important complications of hematopoietic stem cell transplantation (HSCT) that significantly impact the patient's quality life. In this context, study aimed to evaluate profile patients undergoing allogeneic HSCT, assessing GVHD OM occurrence. Data from medical records underwent HSCT between 2019 2021 were collected. Patients ove...

Graft-versus-host disease (GVHD) is an important complication of bone marrow transplantation and is known to induce sweat gland abnormalities. We employed immunohistochemical staining for granulysin, dermcidin as well as IL-17 and Foxp3 in the lesional skin of 7 patients with acute GVHD. Granulysin-bearing cells were distributed in the epidermis, basal membrane zone of the dermis, and superfici...

The liver, skin, and gastrointestinal tract are major target organs of acute graft-versus-host disease (GVHD), the major complication of allogeneic bone marrow transplantation (BMT). In order to gain a better understanding of acute GVHD in the liver, we compared the gene expression profiles of livers after experimental allogeneic and syngeneic BMT using oligonucleotide microarray. At 35 days af...
