Ribavirin promotes liver fibrosis in HCV-positive kidney recipients
Hepatitis Weekly via NewsEdge Corporation :
2005 MAY 23 - (NewsRx . com ) -- Ribavirin promotes liver fibrosis in HCV-
positive kidney recipients.
According to published research from France, "in untreated hepatitis
virus (HCV)-positive renal transplant patients, the rate of liver
fibrosis progression is low. In contrast, in those treated by
ribavirin monotherapy, liver fibrosis score increased significantly
after only 1 year of ribavirin monotherapy. The aim of this study was
to identify the factors that might contribute to accelerate liver
fibrosis progression in this population."
"Eleven patients were included in the study. Intrahepatic transforming
growth factor (TGF)-beta, interferon (IFN)-gamma, and interleukin
(IL)-10 mRNA quantification determined by real-time reverse
transcription-polymerase chain reaction (RT-PCR) were similar before
and after ribavirin therapy," according to N. Kamar and colleagues,
CHU Rangueil, Department of Nephrology, Dialysis and Transplantation.
"The number of amino acid substitutions observed in the hypervariable
region (HVR)-1 of the HCV genome between baseline and 1 year after
ribavirin monotherapy was low, i.e, 3 (1-11) amino acid substitutions,
suggesting the absence of a high selection pressure induced by
ribavirin. In contrast, due to ribavirin-induced hemolysis, there was
a significant increase in serum ferritin levels (p=0.02) and in
intrahepatic iron deposition (p=0.04). Transferrin level and total
iron-binding capacity decreased significantly during ribavirin
monotherapy (p=0.004).
"The increased liver fibrosis observed in renal transplant patients
receiving ribavirin monotherapy could be related to ribavirin-induced
anemia. Severe chronic hemolysis is responsible for iron overload,
liver iron deposition, and an acceleration in the progression of liver
fibrosis," study authors suggested.
Kamar and colleagues published their findings in the Journal of
Medical Virology (Factors accelerating liver fibrosis progression in
renal transplant patients receiving ribavirin monotherapy for chronic
hepatitis C. J Med Virol, 2005;76(1):61-68).
