BACKGROUND: Peginterferon plus ribavirin treatment induced a sustained virological response in >50% of HCV-RNA-positive individuals enrolled in published clinical trials. AIM: To determine anti-HCV treatment effectiveness at a general population level. PATIENTS AND METHODS: In 2002, a 1:5 random sample of >11 years old inhabitants of a small Italian town (Cittanova) was invited for HCV screening. HCV-RNA-positive individuals were evaluated for antiviral treatment. RESULTS: 1645 of 1924 invited individuals (85.5%) participated in the screening. 84 HCV-RNA-positive individuals were detected: median age was 65 years (range: 32-87); 67% was infected with genotype 1 or 4. Antiviral treatment was judged unnecessary for 43 (51.2%), due to persistently normal alanine aminotransferases, mild disease at liver biopsy or age >70 years without cirrhosis. Twenty-eight of the remaining 41 patients (68.3%) were ineligible for treatment, because of medical/psychiatric contraindications (42.9%), alcohol/drug abuse (17.9%), decompensated cirrhosis/hepatocellular carcinoma (17.9%), not attending official appointments (10.7%), previous intolerance/non-response to interferon plus ribavirin (10.7%). 5 of 13 eligible patients (38.5%) did not receive treatment (4 refused and 1 accidental death). 3 of 8 treated patients (37.5%) reached a sustained virological response. CONCLUSIONS: Although efficacy of anti-HCV therapy improved in recent years, we found that low eligibility to treatment still limited its effectiveness at general population level in a highly endemic town.
