In which stage of an EBV-infection is a selective reduction of immunosuppressive medication reasonable to minimize the risk for PTLD, without putting the transplant recipient at risk of acute rejection episodes due to under immunosuppression?

Aim of study:

Identification of patients at high-risk for PTLD.

Epstein-Barr Virus Infections

Study Type: Observational

Biospecimen Retention:   Samples Without DNA

EDTA plasma for EB viral load, serum for differentiated serology and sodium heparine whole-blood for EBV-specific t cells

Estimated Enrollment: 100
Study Start Date: July 2003
Estimated Study Completion Date: August 2010
Estimated Primary Completion Date: August 2010 (Final data collection date for primary outcome measure)
Detailed Description:

PTLD represents a heterogeneous group of abnormal lymphoid proliferations, generally of B-cells, that occur in the setting of ineffective T-cell function because of pharmacological immunosuppression. Because the vast majority of PTLDs are associated with Epstein-Barr virus (EBV) infection, surveillance of EBV infection may have the potential to prevent the development of PTLD by early intervention. However, the cut-off values of "high" EBV viral load remain badly defined due to a lack of prospective studies and assay standardization. The aim of this ongoing multicenter prospective study is the serial detection of primary EBV infection or reactivation in a homogeneous patient population of pediatric renal transplant recipients during the first 2 years posttransplant by the combined analysis of quantitative EBV viral load by a standardized quantitative PCR technique, EBV serology and EBV-specific T-lymphocytes for the identification of high-risk patients.
