Peripheral Blood Lymphocyte Therapy to Prevent Lymphoproliferative Disorders Caused by Epstein-Barr Virus in Patients Who Have Undergone Transplantation

OBJECTIVES: * Compare the efficacy of Epstein Barr virus (EBV) reactive autologous and allogeneic lymphocyte clones ex vivo in targeting EBV immortalized lymphoblasts in patients undergoing a solid organ transplant or T cell depleted bone marrow transplant. * Determine the efficacy of these regimens as treatment and prophylaxis in those patients who develop EBV viremia or EBV induced lymphoproliferative disease. OUTLINE: Autologous and allogeneic Epstein Barr virus (EBV) reactive lymphocytes are isolated from patients and siblings and tested in vitro for cytotoxic activity. Patients who develop EBV viremia or EBV related lymphoproliferative disease after transplant receive autologous Epstein Barr virus (EBV) reactive lymphocytes IV over 20 minutes. Patients receive allogeneic EBV reactive lymphocytes if autologous lymphocytes fail to control EBV proliferation or when sufficient autologous reactive lymphocytes cannot be isolated. Treatment repeats every 4 weeks in the presence of EBV viremia or lymphoproliferative disease. After 5 patients have received therapy without unacceptable toxicity, patients may receive lymphocytes as prophylactic therapy. Patients are followed at 4 weeks, 8 weeks, 6 months, and 12 months. PROJECTED ACCRUAL: A total of 10-20 patients will be accrued for this study.
