  1. Risk factors associated with chronic hepatitis C virus infection : Limited frequency of an unidentified source of transmission.

    Article - En anglais

    Objectives 

    Risk factors have been studied in patients with acute non-A, non-B hepatitis, and approximately 40-50% have no known risk factor for viral acquisition.

    A significant undefined source of viral transmission has been suggested.

    We sought to clearly delineate the risk factors in a population of patients with documented chronic hepatitis C virus (HCV) infection to assess the magnitude of HCV transmission without known risk factors.

    Methods 

    Risk factor profiles were carefully assessed in 301 consecutive patients with chronic HCV infection.

    Patients were classified by gender and age.

    Overall risk factor distributions were calculated and comparisons were made between groups to detect differences in mode of HCV acquisition.

    Results 

    One hundred ninety-six men and 105 women were studied ; 223 were age <= 45 yr and 78 were>45 yr.

    Overall, 25% of patients had a history of transfusion and 49% had a history of intravenous drug use (IVDU).

    Only 12% had no history of risk factor exposure.

    Men were more likely to have a history of IVDU and less likely to have a history of blood transfusion or sexual exposure/household contact.

    Younger patients were more likely to have a history of IVDU and older patients were more likely to have a history of blood transfusion and to deny all risk factor exposure.

    Conclusions 

    A careful history delineated a potential risk factor for HCV acquisition in 88% of patients with chronic HCV infection. (...)
