About

The purpose of the study is to look at cells of the immune system to see if the cells are different among people with different risk factors that have received a liver transplant. We will enroll 50 patients receiving liver transplant and their donors. Both donor and recipient must participate in the order for the recipient to participate in the study. We will take blood samples from these patients and their donors.

Full description

To establish whether in-vitro donor-specific immune reactivity patterns can differentiate between those liver transplant recipients who are positive for the Hepatitis C virus (HCV) who are at high risk and those who are at low risk for graft loss secondary to early recurrence of HCV.

An assessment of the recipient's donor-specific immune status can be achieved by measuring T-cell activity, specifically alloreactive primed (donor-specific) T cell activity. It has been shown that detection of IFN-y in short-term enzyme-linked-immunosorbent-spot (ELISPOT) assay is consistent with the presence of primed memory T cells (6). In the transplantation setting, T cells of an allograft recipient that secret IFN-y after short in-vitro exposure to donor cells represent a prior sensitization of recipient to donor antigens in vivo. Clinically interpreted - this priming event may signify the presence of an up-coming, or an on-going, rejection episode. Our limited preliminary data suggest an additional potential clinical value for the in-vitro assessment of donor-specific IFN-y production in predicting those liver transplant recipients at higher risk for recurrence of Hepatitis C.
