PURPOSE: Phase II trial to study the effectiveness of peripheral blood lymphocyte therapy in treating and preventing lymphoproliferative disorders in patients who have Epstein-Barr virus infection following transplantation.
- 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.
Primary Purpose: Treatment
allogeneic Epstein-Barr virus-specific cytotoxic T lymphocytes, autologous Epstein-Barr virus-specific cytotoxic T lymphocytes

A common, acute infection usually caused by the Epstein-Barr virus (HERPESVIRUS 4, HUMAN). There is an increase in mononuclear white blood cells and other atypical lymphocytes, generalized lymphadenopathy, splenomegaly, and occasionally hepatomegaly with hepatitis.
A critical subpopulation of regulatory T-lymphocytes involved in MHC Class I-restricted interactions. They include both cytotoxic T-lymphocytes (T-LYMPHOCYTES, CYTOTOXIC) and CD8+ suppressor T-lymphocytes.
Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
Epithelial hyperplasia of the oral mucosa associated with Epstein-Barr virus (HERPESVIRUS 4, HUMAN) and found almost exclusively in persons with HIV infection. The lesion consists of a white patch that is often corrugated or hairy.
A genus of the family HERPESVIRIDAE, subfamily GAMMAHERPESVIRINAE, infecting B-cells in humans and new world primates. The type species human herpesvirus 4 (HERPESVIRUS 4, HUMAN) is better known as the Epstein-Barr virus.
