Filter by:The purpose of this trial is to assess whether an adaptation of cyclosporine (CsA) dose according to a longitudinal calcineurin (CN) activity monitoring would prevent the onset of graft-versus-host disease (GVHD).
This randomized phase III trial is studying low-dose prednisone or methylprednisolone to see how well they work compared with standard-dose prednisone or methylprednisolone in treating patients with newly diagnosed acute graft-versus-host disease (GVHD). Glucocorticoids, such as prednisone or methylprednisolone at a starting dose of 2 mg/kg/day are standard treatment for acute graft-versus-host disease caused by a donor stem cell transplant. It is not yet known whether low-dose glucocorticoids are more effective than standard-dose glucocorticoids in treating acute graft-versus-host-disease
Background: Low-dose chemotherapy is easier for the body to tolerate than typical high-dose chemotherapy and involves a shorter period of complete immune suppression. Donor immune cells called lymphocytes, or T cells, fight residual tumor cells that might have remained in the recipients body after stem cell transplant, in what is called a graft-versus-tumor (GVT) effect. The immune-suppressing drug sirolimus appears to help prevent graft-versus-host disease (GVHD), a side effect of stem cell transplant in which donated T cells sometimes attack healthy tissues, damaging organs such as the liver, intestines and skin. Th2 cells are cells collected from the transplant donor and grown in a high concentration of sirolimus. Objectives: To determine whether stem cell transplantation using low-dose chemotherapy and sirolimus-generated Th2 cells can cause a remission of advanced kidney cancer. Eligibility: Patients between 18 and 75 years of age who have kidney cancer that has spread beyond the kidney and who have a tissue-matched sibling stem cell donor. Design: Patients undergo stem cell transplantation as follows: - Low-intensity chemotherapy with pentostatin and cyclophosphamide over a 21-day period to reduce the level of the immune system to prepare for the transplant. Pentostatin is given through a vein (intravenous (IV)) on days 1, 8 and 15; cyclophosphamide tablets are taken by mouth for 21 consecutive days. - Sirolimus tablets, taken by mouth, starting 2 days before the transplant and continuing until 60 days after the transplant. - IV infusions of stem cells and Th2 cells. Following the transplant, patients have the following procedures: - Additional Th2 cell infusions on days 14 and 45 after the transplant. - Follow-up visits at the National Institutes of Health (NIH) Clinical Center twice a week for the first 6 months after the transplant and then less frequently for at least 5 years to evaluate response to treatment and treatment side effects. Evaluations include a bone marrow aspirate and biopsy 1 month after transplant and periodic blood tests and imaging procedures (e.g., computed tomography (CT) or magnetic resonance imaging (MRI) scans).
RATIONALE: Collecting and storing samples of blood, urine, and tissue from patients undergoing a donor stem cell transplant to test in the laboratory may help the study of graft-versus-host disease in the future. PURPOSE: This research study is collecting and storing tissue and DNA samples from patients undergoing a donor stem cell transplant.
Introduction: Graft-versus-host-disease (GVHD) is the major cause of morbidity and mortality in patients submitted to the Bone Marrow Transplantation (BMT). The oral manifestations can be very debilitating and interfere in the results of medical therapy, leading to systemic complications, committing the prognosis and quality of life of the patient. The early diagnosis can be done through biopsies of oral mucosa with or without apparent injury clinic. The association between the clinical and histopathological tables of GVHD, especially through the use of recent consensus established in these areas, can bring new benefits to physicians. Objective: This study aims to apply and compare the two classifications histological to GVHD, Horn (1995) and Consensus (2006) in specimens obtained from clinical oral lesions suggestive of GVHD; correlate them with clinical classification according Akpek (2001) and with the survival of the patients.
For numerous malignant diseases allogeneic hematopoietic stem cell transplantation (HSCT) is the only curative therapy. One of the major complications is the occurrence of acute graft-versus-host-disease (aGVHD). Thirty to eighty percent of patients after HSCT develop aGVHD despite the prophylactic application of different immunosuppressive drugs. The response rates to the conventional first line treatment are only 15-35%4. In case of a steroid refractory aGVHD different therapeutic strategies have been evaluated, but with no satisfactory results so far. The mortality of patients suffering from steroid refractory aGVHD remains at 75-80%. Therefore, it remains important to search for new therapeutical strategies for the treatment of aGVHD.
Natural Killer (NK) cells play a unique role during innate immune responses as they are able to recognize and eliminate, without specific sensitization, tumors, microbe-infected cells as well as allogeneic cells.In a first time, we will characterize the tissue distribution, the phenotype and the effector functions of NK cells present in the human healthy skin.
