BACKGROUND Needle exchange programmes (NEP) provide injection drug users (IDU) with sterile injection equipment and receive used needles in exchange. In this paper we describe the use of new syringes and NEP by IDU and characteristics associated with using NEP in 1993. METHODS Street-recruited IDU were interviewed in five US locations: Atlanta, Philadelphia, Chicago, New York City, and Los An...

BACKGROUND Injection drug users (IDU) commonly seek manual assistance with illicit drug injections, a practice known to be associated with various health-related harms. We investigated the social structural factors that shape risks related to assisted injection and the harms that may result. METHODS Twenty semi-structured qualitative interviews were conducted with IDU enrolled in the ACCESS o...

BACKGROUND HIV/AIDS related stigma interferes with the provision of appropriate care and support for people living with HIV/AIDS. Currently, programs to address the stigma approach it as if it occurs in isolation, separate from the co-stigmas related to the various modes of disease transmission including injection drug use (IDU) and commercial sex (CS). In order to develop better programs to ad...

BACKGROUND About a third of the global HIV infections outside sub-Saharan Africa are related to injecting drug use (IDU), and this accounts for a growing proportion of persons living with HIV. This paper is a response to the need to monitor the state of the HIV epidemic as it relates to IDU and the availability of HIV treatment and harm reduction services in 21 high epidemic countries. METHOD...

BACKGROUND Injecting drug use continues to be a primary driver of HIV epidemics in many parts of the world. Many people who inject drugs (PWID) are sexually active, so it is possible that high-seroprevalence HIV epidemics among PWID may initiate self-sustaining heterosexual transmission epidemics. METHODS Fourteen countries that had experienced high seroprevalence (<20%) HIV epidemics among P...

BACKGROUND Cohort data examining differences by gender in clinical responses to combination antiretroviral therapy (ART) remain inconsistent and have yet to be explored in a multi-province Canadian setting. This study investigates gender differences by injection drug use (IDU) history in virologic responses to ART and mortality. METHODS Data from the Canadian Observational Cohort (CANOC) coll...

The mechanisms by which DNA-incorporated radionuclides impart lethal damage to mammalian cells were investigated by examining the capacity of dimethyl sulfoxide (DMSO) to protect against lethal damage to Chinese hamster V79 cells caused by unbound tritium ((3)H(2)O), DNA-incorporated (125)I- and (131)I-iododeoxyuridine ((125)IdU, (131)IdU), and cytoplasmically localized (210)Po citrate. The rad...

Background Acquired immune deficiency syndrome (AIDS) is one of the greatest social health problems in many communities in the twenty-first century. Methadone maintenance treatment (MMT) could decrease HIV infection among injection drug users (IDU). The main aim of this paper was to determine the cost-effectiveness of the governmental MMT program to prevent human immunodeficiency virus (HIV) in...

BACKGROUND We report on an exercise to estimate the prevalence of injecting drug use (IDU) and associated harms in a single primary care trust. METHODS Covariate capture-recapture methods to estimate (i) IDU prevalence; respondent driven sampling to measure (ii) prevalence of HCV and HIV and record linkage to measure (iii) mortality risk. RESULTS (i) The overall estimated number of IDU was ...

Injection drug use has been the most growing rout of drug abuse in Iran in the past decade and it has been responsible for the transmission of HIV virus in more than two third of cases. The aim of the present study was to determine the prevalence of HIV and hepatitis B in a group of IDU cadavers and to compare the results to a group of cadavers of the normal population. In a case-control study ...
