BACKGROUND: Illicit drug use (DU) and hazardous drinking (HD) among marginalized populations may be associated with greater barriers to care. METHODS: We used baseline data on the participants of the Seek, Test, Treat, and Retain data harmonization initiative. DU includes use of any illicit drugs within the past 6 months. HD was defined as scores ≥8 for men and ≥ 7 for women on Alcohol Use Disorders Identification Test within the past 12 months. Social support scores were assigned by summing scores from individual questions related to social support...

BACKGOUND: Intravenous drug users (IVDUs) are among the high-risk groups who are most vulnerable to HIV infection. Several illicit drugs alter host immune function with increased incidence of infections including that of HIV. Many studies of the immune response of NK cells in HIV-1 seronegative IVDUs and HIV-1 seropositive IVDUs have been published from the Western countries and yet no data is available from Thailand. OBJECTIVE: To determine natural killer cell cytotoxicity and lymphocyte subsets in Thai HIV-1 infected intravenous drug users...

Background: This paper explores associations between use of party-and-play drugs, including crystal methamphetamine, and wellbeing among HIV positive gay and bisexual men (GBM) in Australia. This study considers whether use of drugs in a social or sex-based setting facilitates access to social and support networks, which may in turn support wellbeing. Methods: A cross-sectional survey of Australian people living with HIV (PLHIV) was conducted. There were 714 participants (79.7%) who identified as GBM. Differences between party-and-play drug users and non-users were examined using bivariate and multinomial logistic regressions...

BACKGROUND: The HIV care cascade has improved in Latin America over the last decade. However, the influence of alcohol and noninjected drug use (NIDU) on cascade outcomes is mostly unknown. This study estimated the association of alcohol and NIDU with retention in care, loss to follow up (LTFU), and virologic failure (VF). METHODS: Individuals ≥18 years attending routine HIV clinic visits and completing the Rapid Screening Tool (RST; evaluating NIDU and ART adherence in 7-day recall period) during 2012-13 were followed up to 2015 in the Caribbean, Central and South America network for HIV epidemiology...

Introduction: In low/middle-income countries with substantial HIV and tuberculosis epidemics, health services often neglect other highly prevalent chronic conditions, such as hypertension, which as a result are poorly managed. This paper reports on a study to assess the effect on hypertension management of lay health workers (LHW) working in South African rural primary healthcare clinics to support the provision of integrated chronic care. Methods: A pragmatic cluster randomised trial with a process evaluation in eight rural clinics assessed the effect of adding two LHWs supporting nurses in providing chronic disease care in each intervention clinic over 18 months...

OBJECTIVES: People who inject drugs (PWID) represent the main risk group for hepatitis C virus (HCV) infection in most middle and high-income countries. Testing PWID is considered as an important prevention measure. Identification of PWID characteristics associated with HCV testing may contribute to strategies targeting the containment of the HCV and HIV epidemics in Greece. METHODS: Anonymous behavioural data from 2747 heroin users were collected upon entry in 38 opioid substitution treatment (OST) clinics in Greece during the period 2013-2015...

Background: Cannabis is a widely used drug in the United States, and the frequency of cannabis use in the human immunodeficiency virus (HIV)-infected population is disproportionately high. Previous human and macaque studies suggest that cannabis may have an impact on plasma viral load; however, the relationship between cannabis use and HIV-associated systemic inflammation and immune activation has not been well defined. Methods: The impact of cannabis use on peripheral immune cell frequency, activation, and function was assessed in 198 HIV-infected, antiretroviral-treated individuals by flow cytometry...

OBJECTIVES: Although previous cross-sectional studies have identified correlates of detectable plasma HIV-1 RNA viral load (VL) among HIV-positive people who use drugs (PWUD), longitudinal factors associated with heightened HIV transmission potential have not been well described. Therefore, we longitudinally examined factors associated with amount of person-time spent above log10(1500) copies/ml plasma among HIV-positive PWUD in Vancouver, Canada. DESIGN: Data were derived from a long-running prospective cohort of HIV-positive PWUD linked to comprehensive clinical records including systematic VL monitoring...

BACKGROUND: Methamphetamine use increases the risk of HIV-1 infection among seronegative users, and can exacerbate disease progression in HIV-positive users. The biological mechanisms underlying these associations remain unclear. In this cross-sectional pilot study, we examine the associations between recent methamphetamine use and inflammation in the rectal mucosa and peripheral blood compartments in HIV-1 seropositive and seronegative men who have sex with men (MSM). METHODS: HIV-seronegative and seropositive MSM participants were enrolled (N=24)...

International best practices call for a gender-responsive approach to HIV prevention for women, including those who use drugs and those who engage in sex work. This paper draws on multiple qualitative data sources collected over five years in Ukraine to explore the notions of gender, women and family that buttress HIV-related programmes for women. Our analysis reveals that service providers often cast women as hapless victims of unfortunate family circumstances and troubled personal relationships that produce sudden poverty, or social strivers who seek access to wealth and privilege at the expense of their health...

Prevention of male-to-female HIV transmission remains a huge challenge and topical pre-exposure prophylaxis (PrEP) using microbicides may help overcoming the problem. In this work, different types of films containing the antiretroviral drugs tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) were developed. Formulations based in poly(vinyl alcohol) and pectin were produced as single- or double-layered films. Films containing TDF/FTC or TDF/FTC-loaded Eudragit® L 100 nanoparticles (NPs) obtained by nano spray-drying were tested for physicochemical, technological and biological properties relevant to microbicide development...

BACKGROUND: Analysis of specific drug use patterns in men who have sex with men (MSM) is important in targeting HIV prevention and harm reduction interventions and in developing a fuller picture of drug use in context beyond consideration of use of specific drugs in isolation. OBJECTIVES: We sought to develop a typology of recent drug use in MSM, and to explore how distribution of MSM across the classes in this typology differs by socio-sexual characteristics. METHODS: We examined last-year drug use reported by 16,814 MSM as part of a cross-sectional, internet-based survey of MSM living in the UK for which data were collected in late summer 2014...
