英文摘要
Background: End-stage liver disease secondary to hepatitis C virus (HCV)
infection is the leading indication for orthotopic liver transplantation
(OLT) in the United States. Recurrence of HCV infection is nearly
universal, with 10 of HCV-infected recipients experiencing early graft
loss or death secondary to recurrent HCV disease. The National
Institutes of Diabetes and Digestive and Kidney Diseases Liver
Transplantation Database (LTD) has recently demonstrated that the pre-
OLT viral load, as measured by HCV RNA, is predictive of patient and
graft survival. It is not known whether lowering pre-OLT viral load will
improve the rate of virological recurrence, or patient or graft survival
following OLT in HCV-infected recipients.
Aims: A planning grant is proposed for the design of a multi-center,
double-blind, randomized, controlled trial incorporating interferon-
alpha (IFN-alpha) and ribavirin to be conducted by the National
Institute of Diabetes and Digestive and Kidney Diseases Liver
Transplantation Database in conjunction with three additional Liver
Transplant Centers. In order to design such a study, the specific aims
of the planning grant proposal are: 1) to establish optimal study size
and duration (power calculations, stratification strategy) through the
virological characterization of the HCV-infected patients currently
awaiting liver transplantation at the participating centers and 2) to
determine the tolerability and efficacy of two forms of IFN-alpha and
ribavirin in patients with end-stage liver disease secondary to HCV.
Methods: HCV-infected patients awaiting OLT at the participating centers
(the Mayo Clinic and Foundation, Mount Sinai Medical Center, New York,
the University of California San Francisco, the University of
Pittsburgh, the University of Nebraska and Baylor University Medical
Center) will be invited to participate in the study. Sixty participants
will be randomized to receive either non-pegylated IFN-alpha alone, non-
pegylated IFN-alpha + ribavirin or pegylated IFN-alpha + ribavirin.
Statistical analysis will be performed by the Graduate School of Public
Health at the University of Pittsburgh.
Significance: The results of the planning phase will facilitate the
design and coordination of the multi-center double-blind, randomized,
controlled trial incorporating IFN-alpha and ribavirin to determine the
effect of lowering pre-OLT HCV RNA titers on posttransplant outcomes,
including HCV recurrence.
