Extended duration therapy with pegylated interferon and ribavirin for patients with genotype 3 hepatitis C and advanced fibrosis: final results from the STEPS trial.

BACKGROUND & AIMS: Patients with genotype 3 hepatitis C virus (HCV) infection and cirrhosis have poor response rates after 24 weeks treatment with pegylated interferon and ribavirin. Treatment for 48 weeks is therefore recommended, although the benefits of this are untested. We examined extended therapy in patients with genotype 3 HCV and advanced fibrosis. METHODS: Multicentre, open labelled randomized trial comparing therapy with 24 weeks pegylated interferon and ribavirin to 48 weeks of the same therapy. RESULTS: 136 patients completed the study. 67 received 24 weeks therapy and the SVR rate (48%) did not differ from that seen in the 69 patients who received 48 weeks therapy (42%). The response rates in patients with biopsy proven cirrhosis (13 patients treated for 24 weeks, 18 patients treated for 48 weeks) or cirrhosis proven on imaging (28 patients treated for 24 weeks and 25 patients treated for 48 weeks) were 46% in those treated for 24 weeks and 40% in those treated for 48 weeks. The differences were not significantly different. Treatment failure was due to relapse in the majority of patients. CONCLUSIONS: Patients with genotype 3 HCV and advanced fibrosis do not benefit from extended therapy with pegylated interferon and ribavirin.

Prevalence of chronic viral hepatitis in people of south Asian ethnicity living in England: the prevalence cannot necessarily be predicted from the prevalence in the country of origin.

The prevalence of hepatitis B and hepatitis C in immigrant communities is unknown. Immigrants from south Asia are common in England and elsewhere, and the burden of viral hepatitis in these communities is unknown. We aimed to determine the prevalence of viral hepatitis in immigrants from south Asia living in England, and we therefore undertook a community-based testing project in such people at five sites in England. A total of 4998 people attending community centres were screened for viral hepatitis using oral fluid testing. The overall prevalence of anti-hepatitis C virus (HCV) in people of south Asian origin was 1.6% but varied by country of birth being 0.4%, 0.2%, 0.6% and 2.7% in people of this ethnic group born in the UK, India, Bangladesh and Pakistan, respectively. The prevalence of hepatitis B surface antigen was 1.2%-0.2%, 0.1%, 1.5% and 1.8% in people of this ethnic group born in the UK, India, Bangladesh and Pakistan, respectively. Analysis of risk factors for HCV infection shows that people from the Pakistani Punjab and those who have immigrated recently are at increased risk of infection. Our study suggests that migrants from Pakistan are at highest risk of viral hepatitis, with those from India at low risk. As prevalence varies both by country and region of origin and over time, the prevalence in migrant communities living in western countries cannot be easily predicted from studies in the country of origin.
