CONTEXT: Sub-Saharan Africa faces an increasing incidence and prevalence of life-limiting and life-threatening conditions. These conditions are associated with a significant burden of pain linked to high morbidity and disability that is poorly assessed and undertreated. Barriers to effective pain management partly relate to lack of access to opioid analgesia and challenges in their administration. OBJECTIVES: To identify country-specific and broader regional barriers to access, as well as the administration of opioids, and generate recommendations for advancing pain management in Southern Africa...

The HIV-1 regulatory protein, trans-activator of transcription (Tat), interacts with opioids to potentiate neuroinflammation and neurodegeneration within the CNS. These effects may involve the C-C chemokine receptor type 5 (CCR5); however, the behavioral contribution of CCR5 on Tat/opioid interactions is not known. Using a transgenic murine model that expresses HIV-1 Tat protein in a GFAP-regulated, doxycycline-inducible manner, we assessed morphine tolerance, dependence, and reward. To assess the influence of CCR5 on these effects, mice were pretreated with oral vehicle or the CCR5 antagonist, maraviroc, prior to morphine administration...

Past drug epidemics have disproportionately criminalized drug addiction among African Americans, leading to disparate health outcomes, increased rates of HIV/AIDS, and mass incarceration. Conversely, the current opioid addiction crisis in the USA focuses primarily on white communities and is being addressed as a public health problem. The 21st Century Cures Act has the potential to reduce racial health disparities in the criminal justice system through the Act's public health approach to addiction and mental health issues...

Cytochrome 2B6 (CYP2B6) has substantial clinical effects on morbidity and mortality and its effects on drug metabolism should be part of hepatotoxicity screening. Examples of CYP2B6's impacts include its linkage to mortality during cyclophosphamide therapy and its role in determining hepatotoxicity and CNS toxicity during efavirenz therapy for HIV infection. CYP2B6 is key to metabolism of many common drugs from opioids to antidepressants, anesthetics, and anticonvulsants. But CYP2B6 has been extremely difficult to express in cell culture, and as a result, it has been largely deemphasized in preclinical toxicity studies...

BACKGROUND: People who inject drugs (PWID) are a key population affected by the global HIV and hepatitis C virus (HCV) epidemics. HIV and HCV prevention interventions for PWID include needle and syringe programmes (NSP), opioid substitution therapy (OST), HIV counselling and testing, HIV antiretroviral therapy (ART), and condom distribution programmes. We aimed to produce country-level, regional, and global estimates of coverage of NSP, OST, HIV testing, ART, and condom programmes for PWID...

BACKGROUND: Sharing of equipment used for injecting drug use (IDU) is a substantial cause of disease burden and a contributor to blood-borne virus transmission. We did a global multistage systematic review to identify the prevalence of IDU among people aged 15-64 years; sociodemographic characteristics of and risk factors for people who inject drugs (PWID); and the prevalence of HIV, hepatitis C virus (HCV), and hepatitis B virus (HBV) among PWID. METHODS: Consistent with the GATHER and PRISMA guidelines and without language restrictions, we systematically searched peer-reviewed databases (MEDLINE, Embase, and PsycINFO; articles published since 2008, latest searches in June, 2017), searched the grey literature (websites and databases, searches between April and August, 2016), and disseminated data requests to international experts and agencies (requests sent in October, 2016)...

BACKGROUND: In Germany, medical care of prisoners is completely separated from extramural health care. The extent and quality of medical care among prisoners in Germany are therefore largely unknown. We performed a secondary data analysis of pharmacy sales data for tuberculosis (TB), HIV, hepatitis C (HCV) and opioid substitution treatment (OST) delivered to prisons in 11 federal states (FS) in Germany between 01/2012 and 03/2013. The aims of this study were to assess (i) the treatment availability for the selected diseases and OST in German prisons, (ii) the proportion of prisoners treated per FS and overall for TB, HIV, HCV and OST during the study period...

BACKGROUND: Substance use is common among people with HIV infection. Alcohol, marijuana, and HIV can have negative effects on cognition. We examined associations between current and lifetime marijuana and alcohol use, and cognitive dysfunction in people with HIV infection. METHODS: We studied a cohort of 215 HIV-infected adults with Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) substance dependence or ever injection drug use. In adjusted cross-sectional regression analyses we tested the associations between current marijuana use, current heavy alcohol use, lifetime marijuana use, lifetime alcohol use, duration of heavy alcohol use (the independent variables), and three measures of cognitive dysfunction (dependent variables): both the i) memory and ii) attention domains from the Montreal Cognitive Assessment (MoCA), and iii) the 4-item cognitive function scale (CF4) from the Medical Outcomes Study HIV Health Survey (MOS-HIV)...

BACKGROUND: Though timely initiation of antiretroviral therapy (ART) is a vital component of effective HIV prevention, care and treatment, people who inject drugs are less likely to receive ART than their non-drug using counterparts. In an effort to increase access to ART for people who inject drugs, we examined perceived benefits, challenges, and recommendations for implementing an integrated methadone and ART service delivery model at an opioid treatment program (OTP) clinic in Dar es Salaam, Tanzania...

Although people with HIV infection (PLWH) are at higher risk of polypharmacy and substance use, there is limited knowledge about potential harms associated with polypharmacy such as falls and fractures in this population. The study objective was to determine whether polypharmacy, as measured by the number and type of medication, is associated with falls and fractures among PLWH and DSM-IV substance dependence in the past year or ever injection drug use (IDU). We identified the number of medications by electronic medical record review in the following categories: (i) systemically active, (ii) non-antiretroviral (non-ARV), (iii) sedating, (iv) non-sedating as well as any opioid medication and any non-opioid sedating medication...

PURPOSE: Injection drug users are at high risk for both infection with blood-borne pathogens, namely, human immune deficiency virus (HIV), hepatitis-B, -C virus, various bacterial infections, as well as early primary and secondary joint degeneration. When total knee arthroplasty (TKA) is anticipated the risk of septic complications is a major concern. The purpose of this study was to assess the clinical and radiographic outcome of patients with a history of intravenous drug use after total knee arthroplasty...

Multi-institutional collaboration offers a promising approach to the dissemination of resources for capacity building and the improvement of the training of new investigators and residents, especially in areas of novel curricular content. Physicians should keep pace with the rapid growth of curricular content in an era of restricted resources. Such collaborations, in which educational entities work together and share resources and infrastructure, have been employed in health care to improve quality of care, capacity building, disparity reduction, and resident training...

INTRODUCTION: A lack of access to hepatitis C virus (HCV) diagnostics is a significant barrier to achieving the World Health Organization 2030 global elimination goal. HCV core antigen (HCVcAg) quantification and dried blood spot (DBS) are appealing alternatives to conventional HCV serology and nucleic acid testing (NAT) for resource-constraint settings, particularly in difficult-to-reach populations. We assessed the accuracy of serum and DBS HCVcAg testing in people who inject drugs in Tanzania using HCV NAT as a reference...

Methadone maintenance therapy (MMT) treats opioid use disorder among people who inject drugs (PWID). To understand why PWID may voluntarily discontinue MMT, we analyzed data from 25 focus groups conducted in five Ukrainian cities from February to April 2013 with 199 participants who were currently, previously, or never on MMT. Using constant comparison method, we uncovered three themes explaining why PWID transition off MMT: (a) purposeful resistance to rigid social control associated with how MMT is delivered and to power asymmetries in provider-patient relationships, (b) self-management of a PWID's "wounded identity" that is common in socially stigmatized and physically sick persons-MMT serves as a reminder of their illness, and (c) the quest for a "normal life" uninterrupted by daily MMT site visits, harassment, and time inefficiencies, resources, and social capital...

BACKGROUND: Needle syringe programmes and opioid substitution therapy for preventing hepatitis C transmission in people who inject drugsNeedle syringe programmes (NSP) and opioid substitution therapy (OST) are the primary interventions to reduce hepatitis C (HCV) transmission in people who inject drugs. There is good evidence for the effectiveness of NSP and OST in reducing injecting risk behaviour and increasing evidence for the effectiveness of OST and NSP in reducing HIV acquisition risk, but the evidence on the effectiveness of NSP and OST for preventing HCV acquisition is weak...

BACKGROUND: Methadone maintenance therapy (MMT) is a mainstay for treating opioid use disorder and preventing and managing HIV among people who inject drugs (PWID). While previous research suggested low dosing of methadone and high rates of discontinuation of MMT among PWID in Thailand, little is known about patients' lived experiences with MMT in this setting. Therefore, we conducted a mixed-methods study to examine barriers to retention in MMT among PWID in Bangkok, Thailand, with particular attention to methadone dosing...
