About

There is a distinct lack of published literature on the effect of combination treatment of PEG-interferon and ribavirin on post-renal transplantation hepatitis C virus (HCV) patients. Small case series have been published utilizing conventional interferon and/or ribavirin and the available data is extremely preliminary in nature. A small retrospective series of patients treated with Pegylated interferon and ribavirin published recently suggests that the treatment may be safe and efficacious. Unpublished reports from a few centers within Saudi Arabia also suggest a good safety profile and reasonable efficacy from this form of combination treatment.

The investigators aim to prospectively study the safety and efficacy of PEG-interferon and ribavirin combination therapy in post-renal transplant HCV-infected patients. Towards this 40 patients with histological evidence of liver disease will be recruited and the efficacy of the above medications studied.

The proposed study aims to evaluate the efficacy and safety of PEG-interferon and ribavirin combination therapy in the treatment of chronic HCV in renal transplant patients in a way that will allow management of such patients in an optimized manner.

Inclusion criteria

Patients, male and female, aged 18 - 68 years
Post renal transplant patients exceeding one year
Anti-HCV (Abbott HCV EIA 2.0, Abbott Diagnostic, Chicago, IL) positive > 6 months AND/OR
Detectable serum quantitative HCV-RNA (Cobas Amplicor HCV Monitor v2.0, Roche Molecular Systems, Pleasanton, CA) with lower limit of detection at 50 IU/mL
Compensated liver disease with the following minimum hematologic and biochemical criteria:
Hemoglobin > 10 g/dL
WBC > 3000/mm3 ; granulocyte count > 1,500/mm3
Platelet count > 75,000/mm3
Albumin within normal limits
TFT within normal limits
ANA < 1:320
Ultrasound of the liver obtained within the preceding 6 months of study entry
Liver biopsy prior to entry confirming a histological diagnosis consistent with HCV necroinflammatory score (METAVIR) > 1, and fibrosis score >/= 2.

Exclusion criteria

Previous treatment with interferon and / or Ribavirin - based therapy for chronic hepatitis C
Co-infection with HBV or HIV
Chronic alcohol abuse (daily consumption > 20 g/day)
Autoimmune or metabolic liver disease liver disease
Active drug-induced hepatitis or HAV
Decompensated liver disease (Child-Pugh classification B or C) including a past history of decompensation
Variceal bleeding
Evidence of severe retinopathy (e.g. CMV retinitis, macula degeneration) or clinically relevant ophthalmological disorder due to diabetes mellitis or hypertension
Neoplastic disease
Patients with a value of alpha-fetoprotein >100 ng/mL will be excluded from the study until imaging studies confirm the absence of HCC. Presence of HCC, as determined by other means will also exclude the patient from histological sampling.
Patients with documented or presumed coronary artery disease or cerebrovascular disease should not be enrolled if, in the judgment of the investigator, an acute decrease in hemoglobin by up to 4 g/dL (40 g/L) (as may be seen with ribavirin therapy) would not be well-tolerated
History of severe psychiatric disease, especially depression. Severe psychiatric disease is defined as treatment with an antidepressant medication or a major tranquilizer at therapeutic doses for major depression or psychosis, respectively, for at least 3 months at any previous time or any history of the following: a suicidal attempt, hospitalization for psychiatric disease, or a period of disability due to a psychiatric disease
Evidence of drug abuse (including excessive alcohol consumption) within one year of study entry
Current pregnancy, ongoing breast feeding or unwilling to have contraception
Bleeding or clotting diatheses
Recent history of renal allograft rejection (< 6 months)
Inability or unwillingness to provide informed consent or abide by the requirements of the study.
History or other evidence of severe illness or any other conditions which would make the patient, in the opinion of the investigator, unsuitable for the study.
History of organ transplantation, other than kidney, with an existing functional graft.
Patients requiring dialysis or in whom dialysis is impending.
