Abstract

AIM:

The aim of the present study was to quantitatively monitor the response of CD95 molecules expressed on CD3(+) T cells (CD95(+)CD3(+) cells) and CD38 molecules expressed on CD8(+) T cells (CD38(+)CD8(+) cells) to ganciclovir treatment after orthotopic liver transplant (OLT) in recipients with active human cytomegalovirus (HCMV) infection.

METHODS:

Blood samples were collected from 20 liver transplanted recipients with active HCMV infection and 24 recipients without HCMV infection. CD95(+)CD3(+) cells and CD38(+)CD8(+) cells were quantitatively detected with QuantiBRITE bead methods by dual-color flow cytometry analysis during the post-transplantation period.

RESULTS:

CD95(+)CD3(+) cells and CD38(+)CD8(+) cells were not significantly different among different ages of healthy adults (P > 0.05). CD95(+)CD3(+) cells and CD38(+)CD8(+) cells were drastically increased in the active HCMV infection group compared with that in the stable group or in the healthy group (P < 0.001), and then they were gradually decreased within the next several weeks after ganciclovir treatment when compared with active HCMV infection recipients (P < 0.001).

CONCLUSIONS:

The present study showed that CD38(+)CD8(+) T cells can be an appropriate immunological marker for early detection and antiviral therapeutic monitoring of HCMV infection. The evaluation of CD95 molecule levels may be used routinely in clinical practice to assess the level of immunosuppression.
