The time progression of allograft damage in patients with recurrent hepatit
is C after orthotopic liver transplantation (OLT) is not precisely determin
ed. The aim of this analysis is to study the progression of disease recurre
nce and its impact on patient and graft survival. Data for 300 patients who
underwent OLT for hepatitis C were analyzed regarding the incidence of his
tological recurrence, risk factors, immunosuppressive regimen, rejection ep
isodes, and survival. For patients with histological recurrence, the timing
and risks for disease progression were analyzed. Data for 30 patients who
underwent retransplantation were studied. Histological recurrence occurred
in 40.3% of patients, 27.2% of whom progressed to bridging fibrosis or cirr
hosis. Eighty-seven percent of the patients experienced recurrence of disea
se within 24 months of OLT. Patients with histological recurrence within 6
months of OLT had an increased risk for progression to cirrhosis compared w
ith patients with recurrence later than 6 months (risk ratio, 2.3). Recurre
nce within I year was associated with decreased patient and graft survival
rates at I and 5 years (65.1% and 56.4% versus 80.6% and 78.4%; P = .004 an
d P = .0008, respectively). Patients with histological recurrence had a gre
ater incidence of acute cellular rejection, as well as multiple episodes of
rejection, steroid-resistant rejections, and greater cumulative doses of c
orticosteroids. Histological recurrence after OLT for hepatitis C is common
and usually occurs within 2 years of OLT, Early recurrence negatively affe
cts patient and graft survival. Host factors impacting on recurrence need f
urther study. A relation between the hepatitis C virus, allograft rejection
, and immunosuppression exists and needs investigation.
