ABSTRACT

Objective:

To explore the characteristics and significance of Epstein-Barr virus-infected lymphocyte cell types in peripheral blood mononuclear cells(PBMC)in post-transplant lymphoproliferative disorder(PTLD)after pediatric liver transplantation.

Methods:

From June 2013 to March 2021, retrospective data analysis was performed for 14 pediatric liver transplant recipients with PTLD.The determination of EBV-DNA in PBMC, plasma and TBNK lymphocyte cells was analyzed.

Results:

EBV-DNA in PBMC showed a high viral load(>10 4 copies/ml)and plasma EBV-DNA was >10 3 copies/ml( n=8). There were dominant B-cell-type infection( n=12)and T/NK-cell-type infection( n=2). After treatment, EBV-DNA in PBMC and plasma turned negative in 7 patients with a decline( n=6)and an increase( n=1). EBV-DNA in B lymphocyte became negative( n=10)with a decline( n=3). In one case, EBV-DNA increased in T, B and NK cells with a high viral load.The remainders recovered after treatment.One case of hemophagocytic syndrome died from a progression of PTLD.

Conclusions:

A large majority of EBV-related PTLD are dominated by B-cell-type infection and a few belong to T or NK-cell-type infection.Patients with T/NK-cell-type infection have a worse response to therapy and poorer prognosis than those with B-cell-type infection.Determination of EBV-infected lymphocyte cell types is of vital research value for treatment and prognosis.
