Successful Treatment of Chronic Hepatitis E After an Orthotopic Liver Transplant With Ribavirin Monotherapy.Exp Clin Transplant. 2015 Jun; 13(3):283-6.EC
Hepatitis E virus infection is increasingly reported as a cause of chronic hepatitis in organ transplant recipients. Besides reduction of immunosuppressive therapy or pegylated-interferon therapy, promising results have been reported for ribavirin monotherapy of hepatitis E virus after kidney transplant. To our knowledge, this is the first report of a successful ribavirin monotherapy for chronic hepatitis E virus infection after and orthotopic liver transplant.
MATERIALS AND METHODS
This is a case report of a 55-year-old man with a diagnosis of chronic hepatitis E (genotype 3f) 26 months after an orthotopic liver transplant. A reduction of immunosuppressive therapy was not tolerated, and the patient did not qualify for pegylated-interferon therapy. Because of progressively elevated liver transaminases accompanied by histologic changes in the liver allograft, ribavirin monotherapy was undertaken for 16 weeks.
We saw a decrease in liver enzymes after 1 week of ribavirin monotherapy. Hepatitis E virus RNA anti-HEV-IgM were tested after 8 weeks of ribavirin therapy, and were both negative. Antiviral therapy was continued for 16 weeks, and hepatitis E virus RNA remained undetectable; there also was a significant decrease in liver transaminases levels to normal values. In the 8-week and 8-month follow-ups at the end of antiviral therapy, the patient presented with normal liver enzymes and no detectable hepatitis E virus RNA.
In conclusion, successful therapy of chronic hepatitis E after an orthotopic liver transplant may be achieved by ribavirin monotherapy and should be considered in patients who are sensitive to a reduction of immunosuppressive therapy or pegylated-interferon therapy.
