BACKGROUND Blood safety warrants strict screening measures to minimize the risk of transmitting blood-borne pathogens. However, transfusion-transmitted infections for which testing is not currently performed continue to be a concern. Among these untested agents is Epstein-Barr virus (EBV) which, in the transplant setting, is associated with lymphoproliferative disease, a potentially fatal cance...
OBJECTIVE To evaluate the role of chemotherapy and/or rituximab for treatment of posttransplant lymphoproliferative disorder (PTLD) in solid organ transplantation. DATA SOURCES A MEDLINE search (1966-May 2007) was conducted using the key words posttransplant lymphoproliferative disorder, solid organ transplantation, chemotherapy, and rituximab. References of relevant articles and abstracts fr...
In a recent phase II clinical trial using banked allogeneic CTL lines to treat EBV-associated posttransplant lymphoproliferative disease, a response rate of 52% was recorded 6 mo posttreatment. Tumor response was associated with an increase in both CTL/recipient HLA matches and CD4(+) T cells within the infused CTL lines. The present study was undertaken to correlate tumor response with CTL spe...
X-linked lymphoproliferative disease (XLP1) is a rare immunodeficiency characterized by severe immune dysregulation and caused by mutations in the SH2D1A/SAP gene. Clinical manifestations are varied and include hemophagocytic lymphohistiocytosis (HLH), lymphoma and dysgammaglobulinemia, often triggered by Epstein-Barr virus infection. Historical data published before improved treatment regimens...
Cytomegalovirus (CMV) remains the most common single infective cause of death following allogeneic bone marrow transplantation (BMT) from major histocompatibility complex (MHC)-identical siblings, whereas Epstein-Barr virus (EBV)-related disease is infrequent. We show here that MHC-unrestricted cytotoxic effector cells in the peripheral blood of BMT recipients are highly effective at killing EB...
The transfer of antigen-specific cellular immunity in human bone marrow transplantation (BMT) was studied in 49 donor-recipient pairs, using a varicella-zoster-virus (VZV) specific lymphoproliferative response (LPR) assay. Posttransplant VZV-LPR could be serially measured in 31 long-term surviving recipients. VZV-specific T-cell immunity was detected in the early posttransplant period in 4 of 1...
