Preemptive therapy for hepatitis C virus after living-donor liver transplantation
ABSTRACT Living-donor liver transplantation (LDLT) is important for patients with end-stage viral hepatitis because of the cadaveric organ shortage. Preliminary results, however, indicate that LDLT might be disadvantageous for patients positive for hepatitis C virus (HCV).
The subjects were 23 patients who underwent LDLT for HCV cirrhosis. All the patients preemptively received antiviral therapy consisting of interferon-alfa2b and ribavirin, which was started approximately 1 month after the operation. The therapy continued for 12 months after the first negative HCV RNA test. The patients were then observed without the therapy for 6 months (group 1). The therapy was continued for at least 12 months even when the HCV RNA test remained positive (group 2). The subjects were removed from the protocol if they could not continue the therapy for 12 months because of adverse effects or could not start the therapy because of early death.
Eight patients were removed from the protocol. Nine patients were assigned to group 1 and the other six to group 2. The sustained virologic response ratio was 39% (9 of 23). There was a significant difference between the groups in the histologic activity score 1 year after the therapy. The cumulated 3-year survival of the HCV-positive patients was 85%, which was comparable with that of patients negative for HCV (n=93 [90%]).
The present preemptive antiviral protocol after LDLT is safe and might warrant a controlled study for confirming its benefit on graft survival.

- "Prevention of graft reinfection may be achieved through eradication of the virus by use of antiviral therapy before transplantation and use of hepatitis C immunoglobulins    . Additionally, after transplantation, antiviral therapy can be used either preemptively to prevent allograft injury in the first weeks    or, more commonly, to prevent progression to cirrhosis in patients with recurrent hepatitis. Management of chronic hepatitis C in liver transplant recipients with recurrent hepatitis C has improved significantly during the past decade. "
ABSTRACT: The aim of our study was to conduct a systematic review of studies evaluating antiviral therapy with pegylated interferon (PEG-IFN) alfa in combination with ribavirin for the management of recurrent hepatitis C after liver transplantation. Data sources included electronic databases and a manual search. Studies evaluating the efficacy and tolerability of PEG-IFN alfa with ribavirin in patients with recurrent hepatitis C were selected for inclusion. The information extracted from each of the selected publications included study design details, patient characteristics, treatment regimens and efficacy and tolerability end points. Nineteen studies including 611 patients were identified. PEG-IFN alfa-2b was used in 16 studies. The mean rate of SVR was 30.2% (range, 8-50%). Dose reduction and discontinuation of treatment were common in these studies (73% and 27.6%, respectively). The lack of an early virologic response (EVR) at 3 months of therapy was the most frequently described predictive factor of nonresponse. Treatment discontinuation and dose reductions due to adverse events were frequent and possibly represent important obstacles to attainment of SVR. EVR at 3 months of treatment should be considered an important predictor of treatment outcome.Journal of Hepatology 09/2008; 49(2):274-87. DOI:10.1016/j.jhep.2008.05.002 · 10.40 Impact Factor

ABSTRACT: To review the use of antiviral therapy as prophylaxis or treatment of virus C liver disease in the liver transplantation setting. A search was made of the literature in PubMed with the strategy liver transplantation AND hepatitis C AND (interferon OR peginterferon OR ribavirin) from 1966 to June 2007 and a manual search of the journals Gastroenterología y Hepatología, Journal of Hepatology and Hepatology between 2001 and June 2007, to identify publications and communications to congresses relating to the subject. The studies identified were selected and evaluated. A total of 48 articles were chosen for review. Hepatitis C virus is one of the main indications for liver transplantation. Post-transplant re-infection is immediate and almost universal, and results, in many cases, in a recurrent liver disease that reduces the patients survival. Four basic therapeutic strategies have been studied: pre-transplant anti-viral treatment, prophylaxis, early or preventative treatment and treatment of acute or chronic recurrent hepatitis C. Currently, the hepatitis C treatment in the liver transplantation setting is based on the use of peginterferon associated with ribavirin as pre-transplant treatment in selected patients or as treatment of recurrent post-transplant hepatitis C, achieving sustained virological responses of around 20% and 35% respectively. The main limitation of these treatments is the high frequency of the adverse effects and interruptions to treatment, meaning it is important to carry out strict follow-up of the treatment safety.Farmacia Hospitalaria 32(2):102-12.

ABSTRACT: Hepatitis C is not cured with liver transplantation. Patients with hepatitis C virus (HCV) infection have reduced graft and patient survivals compared with non-HCV patients following liver transplantation. Both HCV recurrence and fibrosis are accelerated under the influence of transplantation and immunosuppression. Antiviral therapy has been shown to reduce fibrosis progression and graft loss. The goal of therapy is sustained virologic response and reduction of damage. However, the optimal timing and treatment regimen for patients with HCV following transplant is unclear. Following transplant, sustained virologic response rates are reduced and patient tolerance is limited. Improved treatment strategies are needed to reduce patient side effects and increase efficacy in this population of patients.
