About Chronic GVHD
Graft-versus-Host disease (GVHD) is a major complication of allogeneic hematopoietic cell transplantation. GVHD is an inflammatory disease initiated by T cells in the donor graft that recognize histocompatibility and other tissue antigens of the host, and is mediated by a variety of effector cells and inflammatory cytokines. GVHD presents in both acute and chronic forms. The symptoms of cGVHD typically present at between 100 days and three years post-transplant.
Chronic GVHD has features resembling autoimmune and other immunologic disorders such as scleroderma, Sjogren syndrome, primary biliary cirrhosis, wasting syndrome, bronchiolitis obliterans (BO), immune cytopenias and chronic immunodeficiency. The manifestations of cGVHD may be restricted to a single organ or tissue or may be widespread. Chronic GVHD can lead to debilitating consequences, e.g., joint contractures, loss of sight, end-stage lung disease, or mortality resulting from profound chronic immune suppression leading to recurrent or life-threatening infections.
Treatment of cGVHD is a challenge because it can be refractory to frontline immunosuppression. High-dose systemic corticosteroids are used with some success but carry significant toxicity. The risks of prolonged immunosuppression include local and disseminated infections, Epstein-Barr virus associated lymphoproliferative disease, hypothalamic-pituitary-adrenal (HPA) axis suppression, myopathy, glucose intolerance, neuropsychiatric disease and bone demineralization.
