BACKGROUND Tacrolimus (formerly FK 506) is an immunosuppressive drug that works by inhibiting calcineurin, a calcium-dependent protein phosphatase required for immune function. Tacrolimus has been shown to be effective topically in atopic dermatitis and systemically in psoriasis and graft-vs-host disease (GVHD). However, its efficacy in treating cutaneous GVHD when applied topically has not bee...
Acute graft-versus-host disease (GVHD) is the most frequent, morbid complication following allogeneic hematopoietic stem cell transplantation (HSCT). Its clinical toxicity, requirement for intensive immunosup-pressive management, and associated infections lead to the greatest risks of nonrelapse mortality in HSCT recipients. In acute GVHD, donor-derived T lymphocyte-mediated alloreactivity is c...
Splenic T cells from B10 donors were injected into irradiated (B10 x DBA/2)F1 mice. Either 5 or 6 d later, activated donor T cells were recovered from the spleens of these primary F1 (1 degree F1) recipients and transferred to groups of nonirradiated syngeneic F1 (2 degrees F1) recipients. Whereas day-5-activated parental T cells induced the characteristic symptoms of acute graft-vs.-host disea...
This report describes a study of humoral and cellular immune reactivities in 56 patients who have survived for 1 yr to more than 6 yr after marrow transplantation from an HLA-identical sibling for the treatment of aplastic anemia or hematologic malignancy. All were conditioned for the transplant by high doses of cyclophosphamide and/or total body irradiation. Immunologic studies on the marrow d...
Graft versus host disease (GvHD) is one of the most feared adverse events of allogeneic hematopoietic stem cell transplantation. In severe grades of GvHD patients die from infections due to impairment of their immune defense or therapy-refractory involvement of intestines, liver and lung. Extracorporeal photopheresis is an effective treatment for acute and chronic graft versus host disease with...
One of the major drawbacks for unrelated donor (UD) bone marrow transplantation (BMT) is graft-versus-host disease (GVHD). Despite results from randomized trials, antithymocyte globulin (ATG) is not routinely included for GVHD prophylaxis in UD BMT by many centers. One of ways to demonstrate the usefulness of rabbit ATG in UD BMT is to evaluate how its results approximate to those observed in m...
Donor lymphocyte infusions can reinduce complete remission in the majority of patients with chronic myelogenous leukemia (CML) who relapse into chronic phase after allogeneic bone marrow transplantation (BMT). Such infusions are associated with a high incidence of graft-versus-host disease (GVHD) and marrow aplasia. BMT using selective depletion of CD8+ lymphocytes from donor cells reduces the ...
The Ancillary Therapy and Supportive Care Working Group had 3 goals: (1) to establish guidelines for ancillary therapy and supportive care in chronic graft-versus-host disease (GVHD), including treatment for symptoms and recommendations for patient education, preventive measures, and appropriate follow-up; (2) to provide guidelines for the prevention and management of infections and other commo...
Chronic graft versus host disease (GvHD) after allogeneic stem cell transplantation (SCT) may involve any organ system, but male genital involvement is rare. Peyronie's Disease (PD) is an acquired, localized fibrotic disorder of the tunica albuginea, which leads to penile deformity, pain, and eventually to erectile dysfunction. We report the case of a 52 year old African American male with Acut...
The development of chronic graft-versus-host disease (GVHD), which is induced by the transfer of DBA/2 spleen cells into (C57BL/6 x DBA/2)F1 (BDF1) mice, is closely related to diminished donor anti-host CTL activity and host B cell hyperactivation. Therefore, an approach which activates donor CD8+ T cells or suppresses donor CD4+ T cell-host B cell interaction may have clinical utility in the t...
