BACKGROUND Following a heroin shortage, fentanyl and 3-methylfentanyl, known as "China White" and "White Persian", have become the most widely used drugs, along with amphetamine, among injecting drug users (IDUs) in Tallinn, Estonia. METHODS In order to assess the relationships between the injection of fentanyl and amphetamine, and levels of HIV(More)
BACKGROUND Both syringe exchange programs (SEPs) and pharmacy sales of syringes are available in Estonia, though the current high incidence and high prevalence of HIV among injection drug users (IDUs) in Tallinn, Estonia requires large-scale implementation of additional harm reduction programs as a matter of great urgency. The aims of this report were to(More)
BACKGROUND A high copy number of CCL3L1, the most potent human immunodeficiency virus (HIV)-suppressive chemokine, associates with reduced HIV susceptibility. Whether CCL3L1 influences acquisition of multiple blood-borne infections (eg, hepatitis C virus [HCV], HIV, and hepatitis B virus [HBV] infections), which occur commonly among injection drug users(More)
BACKGROUND The paper aims to provide a snapshot of the drug situation in Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan using the EU methodology of "harmonised indicators of drug epidemiology." METHODS Most of the data reported here were gathered and analysed within the framework of the EU-funded CADAP project in 2012. Together with members of CADAP(More)
We used the findings from two, cross-sectional studies of HIV serostatus and risk behaviours to assess the effects of knowledge of HIV serostatus and risk behaviours (relating to sex and injection drug use) among injecting drug users (IDUs). Respondent-driven sampling was used simultaneously at two sites in Estonia (the capital Tallinn, and the(More)
BACKGROUND Estonia has experienced an HIV epidemic among intravenous drug users (IDUs) with the highest per capita HIV prevalence in Eastern Europe. We assessed the effects of expanded syringe exchange programs (SEP) in the capital city, Tallinn, which has an estimated 10,000 IDUs. METHODS SEP implementation was monitored with data from the Estonian(More)
Despite the high number of injecting drug users (IDUs) in Estonia, little is known about involving pharmacies into human immunodeficiency virus (HIV) prevention activities and potential barriers. Similarly, in other Eastern European countries, there is a need for additional sources for clean syringes besides syringe exchange programmes (SEPs), but data on(More)
BACKGROUND Within the fifth phase of the Central Asia Drug Action Programme (CADAP) covering five post-Soviet Central Asian countries, an analysis of the mortality of drug users was performed. The results for Kazakhstan and Uzbekistan are presented in detail in this paper since results from Kyrgyzstan and Tajikistan are not considered valid and Turkmenistan(More)
OBJECTIVES HIV/AIDS risk is embodied within multiple levels including structural and social levels. The aim of this study was to assess the effects of neighbourhood characteristics on HIV prevalence among injection drug users (IDU) residing in the area of Tallinn, Estonia in 2007. METHODS A cross-sectional, multilevel design collecting individual-level(More)
Few recent publications have highlighted theoretical and methodological challenges using respondent-driven sampling (RDS). To explore why recruitment with RDS may work in some populations and not in others, we assess the implementation of RDS to recruit female sex workers (FSWs) and injection drug users (IDUs) into a human immunodeficiency virus biological(More)
