The contribution of two Brazilian multi-center studies to the assessment of HIV and HCV infection and prevention strategies among injecting drug users: the AjUDE-Brasil I and II Projects.

This study assessed 1,144 Brazilian injecting drug users (IDUs) recruited on the street through outreach syringe exchange programs by two multi-center cross-sectional studies: 287 IDUs were recruited during the AjUDE-Brasil I Project and 857 during the AjUDE-Brasil II Project. IDU characteristics related to drug use and sexual behavior, and legal and health conditions for the two studies were compared, using decision tree and logistic regression for each individual study, with HIV infection as the outcome. Fifty-two percent of IDUs were HIV-infected in AjUDE I versus 36.

Brazilian response to the human immunodeficiency virus/acquired immunodeficiency syndrome epidemic among injection drug users.

The Brazilian response to the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) epidemic is being observed all over the world because of its success. Understanding the role of injection drug users (IDUs) in the epidemic and the political response thereto is a key factor in the control of the epidemic in Brazil. This paper summarizes some of the most important analyses of the Brazilian response to the HIV/AIDS epidemic among and from IDUs.

The dynamics of the human immunodeficiency virus epidemics in the south of Brazil: increasing role of injection drug users.

Changes in human immunodeficiency virus (HIV) infection among injection drug users (IDUs) are provoking a shift in the pattern of the HIV/AIDS epidemic in some regions of Brazil. IDUs living in 2 cities (Porto Alegre and Itajaí) in southern Brazil were contacted, interviewed, and tested for HIV. In 1998, 187 IDUs were surveyed and, in 2000, 352 IDUs.

Estimation of the number of injecting drug users attending an outreach syringe-exchange program and infection with human immunodeficiency virus (HIV) and hepatitis C virus: the AjUDE-Brasil project.

This study estimated the number of street injecting drug user (IDU) clients of a syringe-exchange program (SEP) who were infected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV). A two-sample capture-recapture method was carried out. The first capture listed all interviewed IDUs outreached for syringe exchange from April 1 to May 1, 1998; the second capture involved those outreached from May 2 to June 6, 1998.

[The concepts of risk and prevention from the perspective of injecting drug users].

This paper provides an exploratory analysis, using a qualitative approach, to perceptions by injecting drug users (IDUs) on: (a) risks associated with injecting practices; (b) risks of HIV/AIDS; and (c) prevention of HIV/AIDS. The study was conducted in five harm reduction programs in Brazil (the AjUDE-Brasil Project). Forty semi-structured interviews were carried out.
