    Article - En anglais


    The authors utilized a cohort study among Seattle injection drug users (IDUs) to assess whether participation in a syringe exchange program was associated with incidence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection.

    Susceptible IDU subjects (187 seronegative for antibody to HCV, and 460 seronegative for core antibody to HBV) were identified in drug treatment, corrections, and social service agencies from June 1994 to January 1996, and followed for seroconversion one year later.

    The subjects included in the analysis were Seattle-King County (Washington State) area IDUs enrolled in a larger multipurpose cohort study, the Risk Activity Variables, Epidemiology, and Network Study (RAVEN Study).

    There were 39 HCV infections (20.9/100/year) and 46 HBV infections (10.0/100/year).

    There was no apparent protective effect of syringe exchange against HBV (former exchange users, relative risk (RR)=0.68,95% confidence interval (Cl) 0.2-2.5 ; sporadic exchange users, RR=2.4,95% Cl 0.9-6.5 ; regular users, RR=1.81,95% Cl 0.7-4.8 ; vs.

    RR=1.0 for nonusers of the exchange ; adjusted for daily drug injection).

    Neither did the exchange protect against HCV infection (sporadic users, RR=2.6,95% Cl 0.8-8.5 ; regular users, RR=1.3,95% Cl 0.8-2.2 ; vs.

    RR=1.0 for nonusers ; adjusted for recent onset of injection and syringe sharing prior to enrollment). (...)
