    Abstract:
    BACKGROUND: Little is known about the complex stepwise process of giving up intravenous (i.v.) drugs. However, HIV risk reduction programs directed towards i.v. drug users have been accused by some opponents to encourage users to continue. In order to better assess the relationships between risk reduction and abstinence, we studied factors associated with abstinence in HIV-infected patients using i.v. drugs at enrollment in the SEROCO cohort (1988-1994). METHODS: 63 HIV-infected patients injecting i.v. drugs at enrollment were followed-up every 6 months with a clinical examination and a questionnaire concerning sexual and drugs practices since last consultation. Abstinence was defined as non injecting for at least 6 months. The 30 patients who became abstinent during a follow-up period of 3 years were compared to the 33 remaining. RESULTS: Abstinence during follow-up was not related to age at inclusion, duration of i.v. drug use, gender or marital status. However, patients who became abstinent were more likely to have a professional activity at inclusion than the remaining (70% vs 42%, p = 0.03). Before knowledge of HIV infection, frequency of injections, needle sharing and use of condoms did not differ between the 2 groups. During follow-up, behavioural changes occurred in the two groups, but were more marked in those who lately became abstinent. These latter were more likely to always inject with new needles/syringes (57% vs 18%, p = 0.003), and to use condoms with HIV-negative partners or of unknown status (73% vs 39%, p = 0.06). Professional activity and systematic use of new needles/syringes remained independently associated with abstinence in multivariate analysis. CONCLUSION: In this cohort, abstinence appeared as a stepwise process in which risk reduction preceded abstinence. This confirms that risk reduction programs do not work against those messages aimed at stopping i.v. drug use. Since this analysis selected particular subjects, enrolled in a cohort of HIV-infected patients, results should be confirmed in other samples of i.v. drugs users. Few prospective studies have described the stepwise process of giving up intravenous drug (IV) use. In an effort to deepen the understanding of the relationship between risk reduction related to IV drug use and giving up such drug use, the authors studied factors associated with IV drug abstinence among HIV-infected patients using IV drugs at their enrollment in the multicenter French cohort SEROCO between 1988 and 1994. 63 HIV-infected patients injecting IV drugs at enrollment were followed clinically every 6 months and with a questionnaire on their sexual practices and drug use since their most recent consultations. The termination of drug use was defined as not using drugs for a period of at least 6 months. The 30 subjects who gave up IV drug use over the 3-year follow-up were compared to the 33 subjects who continued using IV drugs. Those who gave up IV drugs were more likely to be professionally active at enrollment than those who kept injecting, they more often used during the follow-up period new injection materials for each injection, and more often used condoms with HIV-negative partners and those of unknown serostatus. The abandonment of IV drug use in this study followed a stepwise process in which the reduction of risks preceded the eventual cessation of drug use.
