The efficacy and tolerability of Peg-IFNα-2a and RBV, the cumulative dose effect, time to achieve planned cumulative dose and role of HCV phenotype on treatment response were determined in patients with decompensated HCV-induced cirrhosis.
Recently, elevated bile salt levels were shown to be significantly associated with rates and risk of cirrhosis in patients with chronic hepatitis C virus (HCV) infection treated with pegylated interferon-α2 and ribavirin, suggesting a potential role for bile salt levels in HCV treatment outcomes and in the fibrogenic evolution of HCV-related liver disease.
Between 1998 and 2007, we treated 36 LT recipients for hepatitis C cirrhosis and subsequent HCV recurrence (27 genotype 1 and 9 genotypes 2/3) with pegylated interferon alpha-2a (180 microg/week), pegylated interferon alpha-2b (1.5 microg/kg per week), or standard interferon alpha-2b (3 MIU 3X/week) plus ribavirin (600-1200 mg/day) for 48 weeks.
A total of 71 treatment-naive HCV RNA-positive patients with biopsy-confirmed chronic hepatitis, with genotype 2b or 3a, viral load < or = 3 million copies per ml and no cirrhosis were randomized to receive either standard interferon therapy (3 MIU interferon-alpha-2a thrice weekly) for 26 weeks or 6 MIU interferon-alpha-2a daily for 4 weeks (induction group) followed by the standard dose (3 MIU thrice weekly) for 22 weeks.
In the third Australian multicentre hepatitis C trial, Aushep-3, we examined the efficacy and tolerability of an intensive 24-week course of interferon-alpha 2a in Child-Pugh grade A patients with chronic hepatitis C and cirrhosis.
