Abstract
INTRODUCTION Substance use disorders (SUD) are associated with HIV acquisition and care disruptions. Most research focuses on clinical samples; however, we used a nationally representative, community-based sample to estimate SUD treatment need and utilization by HIV status. METHODS We included participants from the 2015-2019 National Survey on Drug Use and Health aged 18 and older who met past-year DSM-IV SUD criteria (n = 22,166). Participants self-reported whether a healthcare professional ever told them they had HIV or AIDS [i.e., people with HIV (PWH), non-PWH, HIV status unknown]. Outcomes included past-year: 1) any SUD treatment use; 2) any specialty SUD treatment use; and 3) perceived SUD treatment need. Survey weighted multivariable logistic regression models estimated the likelihood of each outcome by HIV status, adjusting for age, sex, race/ethnicity, education, survey year, health insurance status, and household income. RESULTS Overall, 0.5 % were PWH and 0.8 % had an HIV unknown status. Any past-year SUD treatment utilization was low across all groups (10.3 % non-PWH, 24.2 % PWH, and 17.3 % HIV status unknown respondents). Specialty SUD treatment utilization was reported by 7.2 % of non-PWH, 17.8 % PWH, and 10.9 % HIV status unknown respondents. Perceived treatment need was reported by 4.9 % of non-PWH, 12.4 % of PWH, and 3.7 % of HIV status unknown respondents. In adjusted models, PWH were more likely than non-PWH to report any past-year SUD treatment utilization (aOR = 2.06; 95 % CI = 1.08-3.94) or past-year specialty SUD treatment utilization (aOR = 2.07; 95 % CI = 1.07-4.01). Among those with a drug use disorder other than cannabis, respondents with HIV-unknown status were less likely than HIV-negative individuals to report past-year perceived treatment need (aOR = 0.39; 95 % CI = 0.20-0.77). CONCLUSIONS Despite high SUD treatment need among PWH, more than three quarters of PWH with SUD reported no past-year treatment. Compared to non-PWH, PWH had higher treatment utilization and higher specialty treatment utilization, but SUD treatment was low across all groups. As SUD is associated with adverse HIV outcomes, our findings highlight the need for the integration of SUD treatment with HIV testing and care. Increasing access to SUD treatment could help reduce negative SUD-related outcomes along the HIV care continuum.

Past-year medical and non-medical opioid use by HIV status in a nationally representative US sample: Implications for HIV and substance use service integration. JOURNAL OF SUBSTANCE USE AND ADDICTION TREATMENT 2023; 147:208976. [PMID: 36827878 PMCID: PMC10100645 DOI: 10.1016/j.josat.2023.208976] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 12/22/2022] [Accepted: 01/31/2023] [Indexed: 02/19/2023]
Abstract
AIM In the context of the continued overdose epidemic, recent population estimates of opioid use in highly affected groups, such as people at risk for or people living with HIV (PLWH), are essential for service planning and provision. Although nonmedical opioid use is associated with HIV transmission and with lowered adherence and care engagement, most studies rely on clinic-based samples and focus on medical use of opioids only. We examine associations between opioid-related outcomes by HIV status in a community-based nationally representative sample. METHODS The 2015-2019 National Survey on Drug Use and Health included 213,203 individuals aged 18 and older. Respondents self-reported whether a health care professional ever told them they had HIV/AIDS (i.e., HIV-positive/PLWH, HIV-negative, HIV-unknown). Opioid-related outcomes included past-year medical opioid use and past-year nonmedical (i.e., prescription opioid and heroin) use. Multinomial logistic regression estimated adjusted relative risk ratios between past-year opioid-related outcomes and HIV status, controlling for age, gender, race/ethnicity, income, population density, and year. RESULTS In 2015-2019, 0.2 % of respondents were PLWH and 0.3 % self-reported an HIV-unknown status. Past-year medical opioid use was 37.3 % among PLWH, 30.4 % among HIV-negative and 21.9 % among HIV-unknown individuals. Past-year nonmedical use was 11.1 % among PLWH, 4.2 % among HIV-negative and 7.2 % among HIV-unknown individuals. Compared to HIV-negative individuals, PLWH had 3.21 times higher risk of past-year nonmedical use vs. no use (95 % CI:2.02-5.08) and 2.02 times higher risk of past-year nonmedical vs. medical opioid use only (95 % CI:1.24-2.65). CONCLUSION Nonmedical opioid use prevalence was almost three times higher among PLWH than HIV-negative individuals. Because opioid use and its related harms disproportionately burden PLWH, integrating HIV and substance use prevention and treatment services may improve both HIV-related and opioid-related outcomes, including overdose.

Abstract
BACKGROUND People who inject drugs living with HIV (PWIDLH) suffer the lowest rates of HIV viral suppression due to episodic injection drug use and poor mental health coupled with poor retention in HIV care. Approximately 44% of PWIDLH along the US-Mexico border are retained in care and only 24% are virally suppressed. This underserved region faces a potential explosion of transmission of HIV due to highly prevalent injection drug use. This protocol describes an optimization trial to promote sustained viral suppression among Spanish-speaking Latinx PWIDLH. METHODS The multiphase optimization strategy (MOST) is an engineering-inspired framework for designing and building optimized interventions and guides this intervention. The primary aim is to conduct a 24 factorial experiment in which participants are randomized to one of 16 intervention conditions, with each condition comprising a different combination of four behavioral intervention components. The components are peer support for methadone uptake and persistence; behavioral activation therapy for depression; Life-Steps medication adherence counseling; and patient navigation for HIV care. Participants will complete a baseline survey, undergo intervention, and then return for 3-,6-,9-, and 12-month follow-up assessments. The primary outcome is sustained viral suppression, defined as viral loads of < 40 copies per mL at 6-,9-, and 12-month follow-up assessments. Results will yield effect sizes for each component and each additive and interactive combination of components. The research team and partners will make decisions about what constitutes the optimized multi-component intervention by judging the observed effect sizes, interactions, and statistical significance against real-world implementation constraints. The secondary aims are to test mediators and moderators of the component-to-outcome relationship at the 6-month follow-up assessment. DISCUSSION We are testing well-studied and available intervention components to support PWIDLH to reduce drug use and improve their mental health and engagement in HIV care. The intervention design will allow for a better understanding of how these components work in combination and can be optimized for the setting. TRIAL REGISTRATION This project was registered at clinicaltrials.gov (NCT05377463) on May 17th, 2022.

Abstract
Background: Methadone maintenance treatment (MMT) is an effective treatment for opioid use disorder. However, subtherapeutic dosing may lead to continued opioid use by failing to suppress opioid withdrawal and craving. Preclinical and pilot experimental research suggests that cannabinoids may reduce opioid withdrawal and craving. We sought to test whether the association between low methadone dose and illicit opioid use differs according to concurrent cannabis use patterns. Methods: Data for this study were derived from two community-recruited cohorts of people (≥18 years old) who use illicit drugs in Vancouver, Canada. We used generalized estimating equations to estimate the adjusted association between lower daily MMT dose (<90 mg/day) and daily illicit opioid use, testing for interaction between dose and daily cannabis use. Results: Between December 2005 and December 2018, 1389 participants reported MMT enrolment and were included in the study. We observed a significant interaction (p<0.01) between daily cannabis and lower MMT dose on concurrent daily illicit opioid use: lower MMT doses increased the odds of daily illicit opioid use by 86% (adjusted odds ratio [AOR]=1.86, 95% confidence interval [CI]=1.61-2.16) during periods of no or low-frequency cannabis use and by 30% during periods of daily cannabis use (AOR=1.30, 95% CI=1.01-1.67). Discussion: This study provides preliminary observational evidence that cannabis may mitigate some of the negative effects of subtherapeutic MMT dosing, guiding future clinical investigations into the safety and efficacy of cannabis and cannabinoids as adjunct treatment for MMT.

Abstract
OBJECTIVES Lower daily methadone dose is negatively associated with retention in methadone maintenance treatment (MMT). Cannabis use during MMT is common, with many patients reporting its use for opioid withdrawal mitigation. We sought to test whether the association between lower MMT dose and treatment retention differs by concurrent high-frequency cannabis use in a community sample of people on MMT. METHODS We obtained data from participants initiating MMT in 2 community-recruited prospective cohorts of people who use drugs in Vancouver, Canada. We built multivariable Cox frailty models to estimate the relationships between MMT dose (<90 mg/d vs ≥90 mg/d) and time to treatment discontinuation. We included an interaction term to test whether high-frequency (≥daily) cannabis use modified the measured effect of lower treatment dose on treatment retention. RESULTS Between December 2005 and December 2018, 829 participants (54.1%) initiated at least 1 MMT episode and were included in the analysis. Lower MMT dose was strongly positively associated with treatment discontinuation regardless of concurrent high-frequency cannabis use (interaction P > 0.05). Structural factors including homelessness and incarceration were significantly and positively associated with treatment discontinuation. CONCLUSIONS Although we previously found the magnitude and strength of the relationship between lower MMT dose and high-frequency unregulated opioid use to be tempered during high-frequency cannabis use periods, this effect measure modification does not appear to translate to time retained in treatment. Cannabis-based interventions to promote retention in MMT are unlikely to produce long-term benefit without addressing external factors that place MMT patients at increased risk of treatment discontinuation.

Abstract
BACKGROUND Methadone treatment of opioid use disorder in HIV-infected individuals is complicated by drug-drug interactions. Genetic and other cofactors further contribute to interindividual variability in methadone pharmacokinetics. We used population pharmacokinetics to estimate the effect of drug-drug interactions, genetics, and other cofactors on methadone pharmacokinetics in a methadone maintained population in Vietnam. METHODS Plasma R- and S-methadone levels were measured in 309 methadone maintained individuals just before and 2-5 h following methadone dosing. A linear one-compartment population pharmacokinetic model with first-order conditional estimation with interaction was used to evaluate methadone clearance (CL/F) and volume of distribution (V/F). The influence of covariates on parameter estimates was evaluated using stepwise covariate modeling. Covariates included HIV status, antiretroviral use (efavirenz or nevirapine), weight, BMI, age, methadone dose, and 8 single nucleotide polymorphisms in across the CYP2B6, ABCB1, and NR1I3 genes. RESULTS Taking either efavirenz or nevirapine increased R-methadone CL/F 220%. Nevirapine and efavirenz increased S-methadone CL/F by 404% and 273%, respectively. Variants in NR1I3 increased R- and S-methadone CL/F by approximately 20% only in patients taking efavirenz. Different alleles in ABCB1 rs2032582 either increased or decreased R-methadone CL/F by 10%. The CYP 2B6*4 variant decreased S-methadone CL/F by 18%. HIV-infection increased R- and S-methadone CL/F and V/F by 24%-39%. CONCLUSIONS The HIV antiretrovirals nevirapine and efavirenz significantly increase methadone clearance. Variants inNR1I3 increased the effect of efavirenz on methadone clearance. Other variants affecting methadone CL/F were also confirmed. To our knowledge, this is the first report of HIV itself affecting methadone pharmacokinetics.

Abstract
The opioid epidemic has fueled infectious disease epidemics. We determined the impact of medications for opioid use disorder (MOUD) on treatment outcomes of opioid use disorder (OUD)-associated infectious diseases: antiretroviral therapy (ART) adherence, human immunodeficiency virus (HIV) viral suppression, hepatitis C virus (HCV) sustained virologic response, HCV reinfection, new hepatitis B virus infections, and infectious endocarditis-related outcomes. Manuscripts reporting on these infectious disease outcomes in adults with OUD receiving MOUD compared with those with OUD "not" receiving MOUD were included. Initial search yielded 8169 papers; 9 were included in the final review. The meta-analysis revealed that MOUD was associated with greater ART adherence (odds ratio [OR] = 1.55; 95% confidence interval [CI] = 1.12-2.15) and HIV viral suppression (OR = 2.19; 95% CI = 1.88-2.56). One study suggested a positive association between MOUD and HCV sustained virologic response. There is significant support for integrating MOUD with HIV treatment to improve viral suppression among persons with HIV (PWH) and OUD. Treatment of OUD among PWH should be a priority to combat the opioid and HIV epidemics.

Abstract
AIMS Opioids have been hypothesized to suppress the immune function and worsen outcomes among people living with human immunodeficiency virus (HIV). The study aimed to identify key factors associated with the increased cluster of differentiation 4 (CD4) cell counts among HIV-positive people who inject heroin and receive methadone maintenance treatment (MMT). METHODS This longitudinal study was conducted at a psychiatric hospital in Northern Taiwan. Participants were recruited from 2006 through 2011, and received CD4 cell counts and HIV viral load monitoring once every 4 to 6 months. Trend in CD4 cell counts, defined as change in CD4 cell count over time, was used as the outcome measure. Independent variables included MMT-related factors and baseline characteristics. Baseline characteristics included age, gender, CD4 cell count, HIV viral load, tests for other infections, liver function tests, and urine drug screens. RESULTS Three hundred and fifty one participants were recruited during the study period. The multivariate linear mixed model analysis revealed a higher MMT attendance rate, a higher baseline CD4 cell count, and a shorter duration of MMT were associated with an increase in CD4 cell count over time. CONCLUSIONS The study showed better adherence to MMT was associated with better preserved immune functions. The negative impact of duration of MMT on CD4 cell counts may be ameliorated by improving the attendance rate, initiation of MMT earlier when the baseline CD4 cell count is still relatively high and by the other beneficial effects of MMT, such as healthier lifestyles with reduced use of short-acting opioids.

Abstract
Hepatitis C virus (HCV) prevalence is high among people living with HIV co-infected with HCV, people who inject drugs, men who have sex with men and inmates in correctional settings. The barriers to eliminate HCV among these key populations include diagnosis challenges, lack of awareness, discrimination and stigmatization. In addition, scaling up of HCV treatment has been a challenge in Asia–Pacific with the lack of national policies, targets and unavailability of appropriate direct-acting antivirals regimens. In order to achieve HCV micro elimination within these high-risk populations, novel strategies to improve the cascade of care from diagnosis to treatment with direct-acting antivirals, complemented by behavioral change interventions, harm reduction services for people who inject drugs, civil society led advocacy and policies from the government, will be necessary.

Harm Reduct J 2021; 18:45. [PMID: 33892743 PMCID: PMC8063421 DOI: 10.1186/s12954-021-00495-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Accepted: 04/11/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Injection drug use drives HIV transmission in Southeast Asia, where around a quarter of users are living with HIV. Vietnam developed Methadone Maintenance Therapy (MMT) programs to reduce unsafe drug abuse. Common mental health disorders (CMD), including depression, anxiety and post-traumatic stress disorder (PTSD), can worsen MMT outcomes and are highly prevalent among people living with HIV (PLH). We aimed to characterize HIV and CMD among MMT patients and assess the impact of HIV and CMD on MMT engagement outcomes in Hanoi, Vietnam. METHODS This cross-sectional study was conducted at an urban MMT clinic in Hanoi. Participants were screened for CMD with the relevant sections of the Mini International Neuropsychiatric Interview (MINI). Tabular comparisons and regression models were used to understand the association of HIV and CMD with substance use and methadone compliance. RESULTS Of the 400 MMT participants, 22% were living with HIV, 11% a CMD, 27% reported injection drug use, and 27% reported methadone noncompliance. Around 17% of those with HIV also had a CMD. Reporting non injection and injection drug use were each higher among those with CMD regardless of HIV status. In addition, reporting any drug use was much higher among those with both HIV and CMD than among those with neither (73% vs 31%, p value 0.001). While methadone noncompliance was lower among PLH than among those without HIV (16.3% vs 30.1%, p value 0.010), noncompliance was higher among those with CMD than among those without (40.5% vs 25.6%, p value 0.045). Among those without HIV, noncompliance was higher among those with CMD than among those without, but among those with HIV, the opposite relationship was observed. CONCLUSION There is complex overlap between substance use and methadone noncompliance among MMT patients living with HIV, CMD or both. In this population, we found a high prevalence of CMD and substance use among PLH, and a high prevalence of substance use and methadone noncompliance among those with CMD. Prioritizing provision of mental health care services to MMT patients living with HIV can help improve engagement with substance use disorder treatment and reduce the risk of HIV transmission.

Methadone maintenance therapy service components linked to improvements in HIV care cascade outcomes: A systematic review of trials and observational studies. Drug Alcohol Depend 2021; 218:108342. [PMID: 33097340 PMCID: PMC7750271 DOI: 10.1016/j.drugalcdep.2020.108342] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Revised: 09/17/2020] [Accepted: 10/04/2020] [Indexed: 11/24/2022]
Abstract
BACKGROUND The beneficial links between engagement in methadone maintenance therapy (MMT) and HIV treatment outcomes have been extensively described. Nevertheless, people who use drugs (PWUD) continue to experience suboptimal HIV treatment outcomes. In this systematic review, we sought to identify components of MMT service provision that are associated with improvements in HIV care outcomes across the HIV care cascade. METHODS We searched for peer-reviewed studies in online databases. To be eligible for inclusion in this review, studies must have involved a population or sub-population of PWUD engaged in MMT; report improved uptake of HIV testing, exposure to ART, or HIV-1 RNA plasma viral load suppression; provide details on MMT services; and be published in English between 1 January 2006 until 31 December 2018. RESULTS Out of the 5594 identified records, 22 studies were eligible for this systematic review. Components of MMT services associated with HIV care cascade outcomes described in the studies were classified in three categories of care models: 1) standard MMT care with adequate doses, 2) standard MMT care and alongside additional medical component(s), and 3) standard MMT care, additional medical component(s) as well as informational or instrumental social support. CONCLUSION The few studies identified reflect a scarcity of evidence on the role of social support to increase the benefits of MMT for PWUD who are living with HIV. Further research is needed to assess the role of medical and social service components in MMT care delivery in advancing PWUD along the HIV care cascade.

Abstract
BACKGROUND In addition to numerous infections and frequent pain constantly affecting people living with HIV (PLWH), various risk factors might contribute to prescription drug diversion. The purpose of the study is to map existing evidence on risk factors contributing to prescription drug diversion among PLWH. METHODS Arksey and O'Malley's framework and the recommendation by Levac et al. (2010) guided this study. We searched for relevant literature from the following databases: PubMed; Google Scholar; EBSCOhost (Academic Search Complete, MEDLINE and Newspaper Source), Cochrane, WHO, HIV, ScienceDirect and Open Access Theses and Dissertations. Studies reporting evidence on risk factors contributing to prescription drug diversion and published in the period January 1996 to July 2017 were included. Thematic content analysis was performed to summarize the findings. RESULTS The search identified 734 studies. After full-text screening of the eligible studies, risk factors contributing to prescription drug diversion among PLWH were reported in 20 included studies. It was found that there is limited research on prescription drug diversion among PLWH in low-middle-income countries (LMICs). Risk factors contributing to prescription drug diversion were being a substance user or substance dependent; being male; young in age; being stigmatized; not disclosed HIV status; diagnosed with mental health problems; being HIV infected; poor health and well being; being White; being homeless or not owing a home; having low educational level; having history of diversion, misuse or abuse; in possession of addictive prescriptions; being unemployed and living in high neighbourhood disorder. CONCLUSION Evidence shows that there is limited research on prescription drug diversion among PLWH in LMICs. The study findings show that the risk factors contributing to prescription drug diversion are related with risk factors for HIV transmission and infection.

Abstract
Introduction: Methadone maintenance therapy (MMT) program helped to improve access to antiretroviral therapy (ART) among people who inject drugs (PWID) with human immunodeficiency virus (HIV). However, the time to treatment initiation (TTI) and outcomes of ART intervention in this population have scarcely been analyzed. Objectives: The aim of this study was to analyze the TTI and outcomes of ART among MMT clients in primary health-care centers in Kuantan, Pahang. Materials and Methods: This was a retrospective evaluation of MMT clients from 2006 to 2019. The TTI was calculated from the day of MMT enrolment to ART initiation. The trends of CD4 counts and viral loads were descriptively evaluated. Cox proportional hazard model was used to analyze the survival and treatment retention rate. Results: A total of 67 MMT clients from six primary health-care centers were HIV-positive, of which 37 clients were started on ART. The mean TTI of ART was 27 months. The clients who were given ART had a mean CD4 count of 119 cells/mm3 at baseline and increased to 219 cells/mm3 after 6 months of ART. Only two patients (5.4%) in the ART subgroup had an unsuppressed viral load. The initiation of ART had reduced the risk of death by 72.8% (hazard ratio = 0.27, P = 0.024), and they are 13.1 times more likely to remain in treatment (P < 0.01). Conclusion: The TTI of ART was delayed in this population. MMT clients who were given ART have better CD4 and viral load outcomes, helped reduced death risk and showed higher retention rates in MMT program.

Lake S, St Pierre M. The relationship between cannabis use and patient outcomes in medication-based treatment of opioid use disorder: A systematic review. Clin Psychol Rev 2020; 82:101939. [PMID: 33130527 DOI: 10.1016/j.cpr.2020.101939] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Revised: 10/14/2020] [Accepted: 10/20/2020] [Indexed: 10/23/2022]
Abstract
Despite high rates of cannabis use during medication-based treatment of opioid use disorder (MOUD), uncertainty remains around how cannabis influences treatment outcomes. We sought to investigate the relationship between cannabis use during MOUD and a number of patient outcomes. We searched seven databases for original peer-reviewed studies documenting the relationship between cannabis use and at least one primary outcome (opioid use, treatment adherence, or treatment retention) among patients enrolled in methadone-, buprenorphine-, or naltrexone-based therapy for OUD. In total, 41 articles (including 23 methadone, 7 buprenorphine, 6 naltrexone, and 5 mixed modalities) were included in this review. For each primary outcome area, there was a small number of studies that produced findings suggestive of a supportive or detrimental role of concurrent cannabis use, but the majority of studies reported that cannabis use was not statistically significantly associated with the outcome. No studies of naltrexone treatment demonstrated significantly worse outcomes for cannabis users. We identified methodological shortcomings and future research priorities, including exploring the potential role of adjunct cannabis use for improving opioid craving and withdrawal during MOUD. While monitoring for cannabis use may help guide clinicians towards an improved treatment plan, cannabis use is unlikely to independently threaten treatment outcomes.

Abstract
BACKGROUND Whether HIV-positive injecting drug users (IDUs) are at higher risk of developing drug resistance mutations (DRMs) after methadone maintenance therapy (MMT) than any other HIV-positive population is unclear. OBJECTIVE To compare the incidence of new DRMs in two population groups: antiretroviraltreatment (ART) HIV-positive IDUs and non-drug users. METHODS A prospective cohort of ART HIV-positive patients including IDUs who received MMT (MMT group) and non-drug users (N-MMT group) was established from April 2016 to December 2017 in Guangxi, China. RESULTS Of the 80 participants, 43 were in the MMT group and 37 were in the N-MMT group. Compared with the N-MMT group, the HRs of PIs, NRTIs and NNRTIs for new DRMs in the MMT group was 1.55 (95%CI: 0.28-8.64; P = 0.616), 1.51 (95%CI: 0.44-5.20; P = 0.512) and 0.45 (95%CI: 0.15-1.35; P = 0.155), respectively. There was no dose-response relationship between MMT and new DRMs for PIs, NRTIs and NNRTIs (P > 0.05). The new DRM incidence for NRTIs (138.23 per 104 person-months) was higher than for PIs (94.16 per 104 person-months) and NNRTIs (95.41per 104 person-months) in the MMT group, while the new DRM incidence for NNRTIs (208.24 per 104 person-months) was higher than for PIs (44.13 per 104 person-months) and NRTIs (91.78 per 104 person-months) in the N-MMT group. CONCLUSION Among ART HIV-positive patients, there is no significant difference in the incidence of new DRMs between IDUs receiving MMT and non-drug users. MMT has little impact on the development of DRMs among IDUs.

Assisted injection within supervised injection services: Uptake and client characteristics among people who require help injecting in a Canadian setting. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2020; 86:102967. [PMID: 33039705 PMCID: PMC8026755 DOI: 10.1016/j.drugpo.2020.102967] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 09/18/2020] [Accepted: 09/24/2020] [Indexed: 01/24/2023]
Abstract
BACKGROUND People who require help injecting illicit drugs experience elevated rates of a range of health-related harms, including overdose and acquisition of blood-borne pathogens. In response, some supervised injection services (SIS) in Canada have begun to permit clients to be physically injected by fellow clients or staff members. However, little is known about uptake and characteristics of clients who engage in this practice. We therefore sought to examine factors associated with receiving injection assistance at SIS among people who require help injecting drugs in Vancouver, Canada. METHODS Data were drawn from two community-recruited prospective cohort studies of people who inject drugs (PWID). We used multivariable generalized estimating equation (GEE) analyses with time-updated covariates to identify factors associated with self-reported receipt of injection assistance at SIS. RESULTS Between June 2017 and December 2018, 319 individuals who reported having recently required help injecting were included in the study. Of these, 160 (51.0%) were women and the median age was 42 years at baseline. In total, 54 (16.9%) participants reported receiving injection assistance at a SIS at least once over an average of 3.3 months of follow-up. In multivariable GEE analyses, recent homelessness (Adjusted Odds Ratio [AOR] = 2.04; 95% confidence interval [CI]: 1.13 - 3.66), fentanyl injection (AOR = 3.45; 95% CI: 1.42 - 8.41), non-fatal overdose (AOR = 1.86; 95% CI: 1.02 - 3.38) and enrolment in methadone maintenance therapy (AOR = 1.89; 95% CI: 1.03 - 3.47) were associated with increased odds of receiving injection assistance at SIS. CONCLUSION Although uptake of assisted injection at SIS was relatively low among this sample of people who require help injecting, this practice was associated with several indicators of structural vulnerability and drug-related risk. These findings suggest that accommodating assisted injection within SIS may be providing opportunities to engage and reduce harms among higher-risk subpopulations of PWID in this setting.

Abstract
Objectives: Unhealthy alcohol use is associated with negative health outcomes in clients attending methadone maintenance therapy (MMT) programs. However, debates exist regarding the methadone dose of drinkers, and little is known about the health outcomes of drinkers with other types of alcohol use. This study examined the drinking pattern and its association with methadone dose, and depressive and anxiety symptoms in Chinese clients undergoing MMT. Methods: A secondary data analysis was conducted with data from a large-scale cross-sectional survey of 549 clients of 3 MMT clinics in Wuhan, China. Depression, anxiety, and alcohol dependence were measured with Zung Self-rating Depression Scale, Zung Self-rating Anxiety Scale, and Alcohol Dependence Scale, respectively. Drinking pattern was assessed using 3 indicators: weekly amount of alcohol consumed, weekly frequency of alcohol consumed, and severity of alcohol dependence. Results: The prevalence of current drinking, hazardous drinking, regular drinking, and alcohol abuse/dependence was 29.0%, 10.4%, 14.2%, and 8.7%, respectively. In adjustment analyses, relative to nondrinkers, drinkers had significantly lower weight-based methadone dose (β = −0.136, P = 0.008); hazardous drinkers, irregular drinkers, and drinkers without alcohol abuse/dependence had less severe depression (β = −3.67, P = 0.004; β = −2.37, P = 0.034; β = −3.20, P = 0.001) and anxiety (β = −4.90, P < 0.001; β = −3.24, P = 0.006; β = −4.52, P < 0.001), but drinkers with alcohol abuse/dependence had more severe depression (β = 5.55, P < 0.001) and anxiety (β = 4.31, P = 0.005). Conclusion: In Chinese MMT clinics, drinkers may use alcohol to compensate for inadequate MMT and self-medicate negative emotions. Compared with nondrinkers, the severities of depression and anxiety were lower among drinkers without alcohol abuse/dependence, but higher among those with alcohol abuse/dependence.

Abstract
Purpose of review To summarize the status of HIV and substance use in Central Asia and discuss potential ways to move forward to effective epidemic control among people who inject drugs (PWID) in the region and beyond. Recent findings PWID and their partners remain the population most affected by HIV in Central Asia. Lack of effective substance use prevention and treatment options and limited involvement of PWID-led community-based organizations in HIV programs, combined with the requirement for official registration, stigma and discrimination of PWID, and criminalization of drug use remain key barriers to effective HIV prevention and treatment. Summary Sustainable HIV epidemic control among PWID will not be feasible without decriminalization of drug use, addressing stigma and discrimination and policy changes to enhance uptake of HIV-related prevention, treatment and support services by PWID. It is also critical to ensure adoption of innovations, particularly those that combine evidence-based biomedical, behavioral and structural interventions tailored to the needs of the PWID.

Abstract
BACKGROUND AND AIMS HIV-positive drug users' poor adherence to antiretroviral regimens can pose a significant and negative impact on individual and global health. This review aims to identify knowledge gaps and inconsistencies within the current evidence base and to measure HIV-positive drug users' adherence rates and the factors that influence their adherence. METHODS A search of quantitative and qualitative studies in relation to HIV-positive drug users' adherence to antiretroviral treatment was performed using five databases: Applied Social Sciences Index and Abstract (ASSIA), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, Embase and PsycINFO (Ovid interface). Relevant studies were retrieved based on the inclusion and exclusion criteria stated in the review. Findings were compared, contrasted and synthesized to provide a coherent account of HIV-positive drug users' adherence rates and the factors that influence their adherence. RESULTS The proportion of HIV-positive drug users who achieved ≥ 95% adherence across the studies varied widely, from 19.3 to 83.9%. Adherence rates changed over the course of HIV treatment. The factors that influenced adherence were reported as follows: stigmatization, motivation, active drug use, accessibility and conditionality of HIV and addiction care, side effects and complexity of treatment regimens, forgetfulness and non-incorporation of dosing times into daily schedules. CONCLUSIONS HIV-positive drug users' medication-taking is a dynamic social process that requires health professionals to assess adherence to HIV treatment on a regular basis.

Abstract
OBJECTIVES Among people living with HIV (PLWH), high levels of adherence to prescribed antiretroviral therapy (ART) is required to achieve optimal treatment outcomes. However, little is known about the effects of daily pill burden on adherence amongst PLWH who use drugs. We sought to investigate the association between daily pill burden and adherence to ART among members of this key population in Vancouver, Canada. METHODS We used data from the AIDS Care Cohort to Evaluate Exposure to Survival Services study, a long-running community-recruited cohort of PLWH who use illicit drugs linked to comprehensive HIV clinical records. The longitudinal relationship between daily pill burden and the odds of ≥95% adherence to ART among ART-exposed individuals was analyzed using multivariable generalized linear mixed-effects modeling, adjusting for sociodemographic, behavioural, and structural factors linked to adherence. RESULTS Between December 2005 and May 2014, the study enrolled 770 ART-exposed participants, including 257 (34%) women, with a median age of 43 years. At baseline, 437 (56.7%) participants achieved ≥95% adherence in the previous 180 days. Among all interview periods, the median adherence was 100% (interquartile range 71%-100%). In a multivariable model, a greater number of pills per day was negatively associated with ≥95% adherence (adjusted odds ratio [AOR] 0.87 per pill, 95% confidence interval [CI] 0.84-0.91). Further analysis showed that once-a-day ART regimens were positively associated with optimal adherence (AOR 1.39, 95% CI 1.07-1.80). CONCLUSIONS In conclusion, simpler dosing demands (ie, fewer pills and once-a-day single tablet regimens) promoted optimal adherence among PLWH who use drugs. Our findings highlight the need for simpler dosing to be encouraged explicitly for PWUD with multiple adherence barriers.

Abstract
OBJECTIVES Globally, people living with HIV (PLWH) are at greater risk for various infections and chronic pain, therefore, vulnerable to prescription drug diversion which might negatively impact HIV care. The study purpose is to gather evidence on prescription drug diversion among PLWH. STUDY DESIGN This is a systematic scoping review. METHODS Arksey and O'Malley's framework and recommendation by Levac et al. were used to guide this study. Literature was searched in PubMed, Google Scholar, EBSCOhost (Academic Search Complete, MEDLINE and Newspaper Source) and Open Access Theses and Dissertations. Studies reporting evidence of prescription drug diversion from January 1996 to July 2017 were included. Thematic content analysis was performed to summarize data on the prevalence. RESULTS Twenty-nine studies were eligible for data synthesis. Twenty-six studies were conducted in the United States of America (USA), one study in France and two multicountry studies; one study in Kenya and Uganda and the other study in Botswana, Kenya, Malawi, South Africa; Zimbabwe, India, Thailand, Brazil and the USA. Research evidence shows high prevalence of prescription drug diversion for analgesics and antiretroviral drugs; meanwhile, stimulants and erectile dysfunction drugs were the least diverted drugs among PLWH. There is a research gap in low- to middle-income countries (LMICs) investigating prescription drug diversion among PLWH. CONCLUSION Our findings reveal that diversion of various prescription drug classes among PWLH exists. There is lack of research in LMICs. We recommend research in LMICs where there is high HIV prevalence. PROSPERO REGISTRATION NUMBER CRD42017074076.

Abstract
OBJECTIVES We sought to examine the association between dispensation of methadone maintenance therapy (MMT) and antiretroviral therapy (ART) at the same facility, across multiple low-barrier dispensing outlets, and achieving optimal adherence to ART among people who use illicit drugs (PWUD). METHODS We used data from the AIDS Care Cohort to Evaluate Exposure to Survival Services (ACCESS) study, a long-running study of a community-recruited cohort of HIV-positive PWUD, linked to comprehensive HIV clinical records in Vancouver, Canada, a setting of no-cost, universal access to HIV care. The longitudinal relationship between MMT-ART dispensation at the same facility and the odds of ≥ 95% ART adherence was analysed using multivariable generalized linear mixed-effects modelling. We conducted a further analysis using a marginal structural mode with inverse probability of treatment weights as a sensitivity analysis. RESULTS This study included data on 1690 interviews of 345 ART- and MMT-exposed participants carried out between June 2012 and December 2017. In the final multivariable model, MMT-ART dispensation, compared with nondispensation at the same facility, was associated with greater odds of achieving ≥ 95% adherence [adjusted odds ratio (AOR) 1.56; 95% confidence interval (CI) 1.26-1.96]. A marginal structural model estimated a 1.48 (95% CI 1.15-1.80) greater odds of ≥ 95% adherence among participants who reported MMT-ART dispensation at the same facility compared with those who did not. CONCLUSIONS The odds of achieving optimal adherence to ART were 56% higher during periods in which MMT and ART medications were dispensed at the same facility, in a low-barrier setting. Our findings highlight the need to consider a simpler integrated approach with medication dispensation at the same facility in low-threshold settings.

Abstract
Background HIV spread in injecting drug users (IDU) occurs efficiently between individuals within their social networks. While methadone maintenance treatment has long known to be effective in combating HIV transmission in IDU, the impacts of one’s social connections and HIV status have not been well characterised. A study was conducted with the objective of differentiating the pattern of treatment participation between HIV-positive and negative methadone users and to understand its association with social connections with peers. Methods Attendance data in one calendar year were extracted from a territory-wide electronic clinical record database of over 8000 methadone users attending 19 clinics in Hong Kong, a city with a relatively low HIV prevalence in injecting drug users. A case-control design was used by matching HIV positive methadone users with HIV negative controls. A temporal-social co-occurrence approach was adopted to construct a social network. Multiple logistic regression and network-based analyses were conducted. Results In 2016, a total of 8332 methadone users had attended a clinic at least once, giving 1694016 attendance records that were included in the study. Some 432 methadone, 54 of whom HIV positive, were included in the case-control analyses. Multivariable logistic regression model showed that HIV-positive status was associated with drug injection history (adjusted odds ratio [aOR] 2.28, 95% confidence interval [95% CI] 1.19–4.38), not working fulltime (aOR 3.34, 95% CI 1.15–9.72), ethnic minority (aOR 2.59, 95% CI 1.33–5.02) and minimum daily dose of at least 20mg (aOR 3.64, 95% CI 1.08–12.26). Those having connections with other peers were older (aOR 1.02, 95% CI 1.00–1.04), had a higher mode dose (aOR 1.03, 95% CI 1.02–1.04) and had been admitted to methadone programme for longer time (aOR 1.07, 95% CI 1.02–1.13). Among those with connections, HIV-negative users did not have more connections (median degree centrality 21.00 vs 34.50, p = 0.26) but the network structure was stronger (clustering coefficient 0.65 vs 0.53, p = 0.03). Conclusion The weak and sparse linkages may explain the generally low HIV prevalence and incidence in opioid-dependent persons in Hong Kong. Social support could play a constructive role in harm reduction and ethnic minority community-based organisations could help and reinforce treatment adherence.

J Subst Abuse Treat 2018; 94:41-46. [PMID: 30243416 DOI: 10.1016/j.jsat.2018.08.009] [Citation(s) in RCA: 32] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2018] [Revised: 08/09/2018] [Accepted: 08/21/2018] [Indexed: 12/16/2022]
Abstract
BACKGROUND Methadone maintenance therapy (MMT) continues to be a key treatment for opioid use disorder, although premature discontinuation of MMT can increase risk for overdose and other severe harms. We examined sociodemographic characteristics, substance use patterns and social-structural exposures associated with MMT discontinuation among a cohort of people who use drugs (PWUD) in Vancouver, Canada. METHODS Data were derived from VIDUS and ACCESS, prospective cohorts of PWUD in Vancouver, Canada. The outcome of interest was self-reported discontinuation of MMT within the last six months. Multivariable Generalized Estimating Equations (GEE) were conducted to identify factors independently associated with MMT discontinuation. RESULTS Between 2005 and 2015, 1301 PWUD who had accessed MMT were recruited, among whom 288 (22.1%) discontinued MMT at least once during the study period. In multivariable GEE analyses, homelessness (Adjusted Odds Ratio [AOR] = 1.46, 95% Confidence Interval [95% CI]: 1.09-1.95), daily heroin injection (AOR = 5.17, 95% CI: 3.82-6.99), daily prescription opioid use (injection or non-injection) (AOR = 2.18, 95% CI: 1.30-3.67), recent incarceration (AOR = 1.46, 95% CI: 1.01-2.12), and not being on any form of income assistance (AOR = 2.14, 95% CI: 1.33-3.46) were each independently positively associated with MMT discontinuation. Participants with more study visits on methadone (>50% vs. ≤50% of visits) (AOR = 0.63, 95% CI: 0.47-0.85) and those with higher methadone dose (>100 mg vs. <60 mg per day) (AOR = 0.44, 95% CI: 0.31-0.62) were less likely to discontinue MMT. DISCUSSION AND CONCLUSIONS Discontinuation of MMT in this urban setting was associated with recent homelessness and incarceration, not accessing social income assistance, as well as daily prescription opioid use and daily heroin injection drug use. These findings underscore a need to reduce potential barriers to MMT retention by providing access to stable housing and preventing treatment interruptions during transitions between community and custodial settings.

Abstract
BACKGROUND Our previous research has found low and stable mean drug treatment coverage among people who inject drugs (PWID) across 90 large US metropolitan statistical areas (MSAs) during 1993-2002. This manuscript updates previous estimates of change in drug treatment coverage for PWID in 90 MSAs during 1993-2007. METHODS Our drug treatment sample for calculating treatment coverage includes clients enrolled in residential or ambulatory inpatient/outpatient care, detoxification services, and methadone maintenance therapy at publicly- and privately-funded substance abuse agencies receiving public funds. Coverage was measured as the number of PWID in drug treatment, calculated by using data from the Substance Abuse and Mental Health Service Administration, divided by numbers of PWID in each MSA. We modeled change in drug treatment coverage rates using a negative binomial mixed-effects model. Fixed-effects included an intercept and a main effect for time. Incidence rate ratios (IRR) were calculated for both average change from 1993 to 2007 and MSA-specific estimates of change in coverage rates. RESULTS On average over all MSAs, coverage was low in 1993 (6.1%) and showed no improvement from 1993 to 2007 (IRR = 0.99; 95% CI, 0.86, 1.2). There was modest variability across MSAs in coverage in 1993 (log incidence rate SD = 0.36) as well as in coverage change from 1993 to 2007 (log IRR SD = 0.32). In addition, results indicate significant variability among MSAs in coverage. CONCLUSIONS Inadequate treatment coverage for PWID may produce a high cost to society in terms of the spread of overdose mortality and injection-related infectious diseases. A greater investment in treatment will likely be needed to have a substantial and more consistent impact on injection drug use-related harms. Future research should examine MSA-level predictors associated with variability in drug treatment coverage.

Abstract
PURPOSE OF REVIEW People who use drugs face multiple challenges to achieve optimal HIV treatment outcomes. This review discusses the current knowledge in substance use and antiretroviral therapy adherence, highlighting recent findings and potential interventions. RECENT FINDINGS Studies continue to demonstrate the negative impacts of substance use and related disorders on antiretroviral therapy adherence, with the exception of cannabis. Evidence-based addiction treatment, in particular, opioid agonist therapy, appears to improve adherence levels. Most individual-level adherence specific interventions did not provide sustained effects, and no studies evaluating structural-level interventions were found. Findings suggest the urgent need to scale-up opioid agonist therapy, as well as to simultaneously address multiple structural barriers to care to optimize HIV treatment outcomes among people who use drugs.

Social and structural factors associated with greater time with a plasma HIV-1 RNA viral load above log10(1500) copies/ml among illicit drug users. AIDS 2018; 32:1059-1067.

Abstract
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. METHODS We used generalized estimating equations modeling to longitudinally examine factors associated with person-time (in days) with a VL more than log10(1500) copies/ml plasma in the previous 180 days. RESULTS Between December 2005 and May 2014, 845 PWUD were eligible and included in the study. Participants spent an average of 26.8% of observation time with a VL more than log10(1500) copies/ml. In multivariable analyses, homelessness (Adjusted Rate Ratio [ARR] = 1.45) and lack of social support (ARR = 1.27) were positively associated with person-time with a VL more than log10(1500) copies/ml. Older age (ARR = 0.97) and enrolment in addiction treatment (ARR = 0.75) were negatively associated with the outcome in multivariable analyses (all P < 0.05). CONCLUSION Social and structural factors, including periods of homelessness or lacking in social support, were independently associated with greater amount of time with heightened HIV transmission potential. These findings suggest the need for targeted efforts to address modifiable contextual factors that contribute to increased risk of onward HIV transmission among PWUD.

The impact of methadone maintenance therapy on access to regular physician care regarding hepatitis C among people who inject drugs. PLoS One 2018; 13:e0194162. [PMID: 29579073 PMCID: PMC5868786 DOI: 10.1371/journal.pone.0194162] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2017] [Accepted: 02/26/2018] [Indexed: 12/27/2022] Open
Abstract
Background & aims People who inject drugs (PWID) living with hepatitis C virus (HCV) infection often experience barriers to accessing HCV treatment and care. New, safer and more effective direct-acting antiviral-based therapies offer an opportunity to scale-up HCV-related services. Methadone maintenance therapy (MMT) programs have been shown to be effective in linking PWID to health and support services, largely in the context of HIV. The objective of the study was to examine the relationship between being enrolled in MMT and having access to regular physician care regarding HCV among HCV antibody-positive PWID in Vancouver, Canada. Design Three prospective cohort studies of people who use illicit drugs. Setting Vancouver, Canada. Participants We restricted the study sample to 1627 HCV-positive PWID between September 2005 and May 2015. Measurements A marginal structural model using inverse probability of treatment weights was used to estimate the longitudinal relationship between being enrolled in MMT and having a regular HCV physician and/or specialist. Findings In total, 1357 (83.4%) reported having access to regular physician care regarding HCV at least once during the study period. A marginal structural model estimated a 2.12 (95% confidence interval [CI]: 1.77–2.20) greater odds of having a regular HCV physician among participants enrolled in MMT compared to those not enrolled. Conclusions HCV-positive PWID who enrolled in MMT were more likely to report access to regular physician care regarding HCV compared to those not enrolled in MMT. These findings demonstrate that opioid agonist treatment may be helpful in linking PWID to HCV care, and highlight the need to better engage people who use drugs in substance use care, when appropriate.

Abstract
We used latent class analysis to identify substance use patterns for 1363 women living with HIV in Canada and assessed associations with socio-economic marginalization, violence, and sub-optimal adherence to combination antiretroviral therapy (cART). A six-class model was identified consisting of: abstainers (26.3%), Tobacco Users (8.81%), Alcohol Users (31.9%), 'Socially Acceptable' Poly-substance Users (13.9%), Illicit Poly-substance Users (9.81%) and Illicit Poly-substance Users of All Types (9.27%). Multinomial logistic regression showed that women experiencing recent violence had significantly higher odds of membership in all substance use latent classes, relative to Abstainers, while those reporting sub-optimal cART adherence had higher odds of being members of the poly-substance use classes only. Factors significantly associated with Illicit Poly-substance Users of All Types were sexual minority status, lower income, and lower resiliency. Findings underline a need for increased social and structural supports for women who use substances to support them in leading safe and healthy lives with HIV.

Abstract
Cultural adaptation is a research strategy used to tailor evidence-informed interventions for new populations and settings. We describe a pragmatic approach used to culturally adapt a nurse-led medication adherence intervention, Adherence Through Home Education and Nursing Assessment (ATHENA), for prisoners living with HIV in Indonesia. Researchers reviewed data from completed studies in Indonesia and identified core components of the ATHENA intervention considered essential for effectiveness. Adaptations likely to render ATHENA acceptable and feasible in the Indonesian prison setting were proposed. An intervention led by nurses and peer educators was feasible and congruent with existing models in Indonesian prisons. Involving prisoners with HIV in successive developmental phases helped to ensure a good cultural fit. In the context of prisons and other freedom-limiting environments, a pragmatic approach that integrates members of the target population within an anti-oppressive Freirian pedagogical framework is highly appropriate for adapting evidence-informed interventions.

Abstract
Objectives HIV-related mortality is increasing in Indonesia, where prisons house many people living with HIV and addiction. We examined all-cause mortality in HIV-infected Indonesian prisoners within prison and up to 24 months postrelease. Materials and methods Randomly selected HIV-infected male prisoners (n=102) from two prisons in Jakarta, Indonesia, completed surveys in prison and were followed up for 2 years (until study completion) or until they died or were lost to follow-up. Death dates were determined from medical records and interviews with immediate family members. Kaplan–Meier and Cox proportional hazards regression models were analyzed to identify mortality predictors. Results During 103 person-years (PYs) of follow-up, 15 deaths occurred, including ten in prison. The crude mortality rate within prison (125.2 deaths per 1,000 PYs) was surpassed by the crude mortality rate (215.7 deaths per 1,000 PYs) in released prisoners. HIV-associated opportunistic infections were the most common probable cause of death. Predictors of within-prison and overall mortality were similar. Shorter survival overall was associated with being incarcerated within a specialized “narcotic” prison for drug offenders (hazard ratio [HR] 9.2, 95% confidence interval [CI] 1.1–76.5; P=0.03), longer incarceration (HR 1.06, 95% CI 1.01–1.1; P=0.01), and advanced HIV infection (CD4+ T-cell count <200/µL, HR 4.8, 95% CI 1.2–18.2; P=0.02). Addiction treatment was associated with longer survival (HR 0.1, 95% CI 0.01–0.9; P=0.03), although treatment with antiretroviral therapy (ART) or methadone was not. Conclusion Mortality in HIV-infected prisoners is extremely high in Indonesia, despite limited provision of ART in prisons. Interventions to restore immune function with ART and provide prophylaxis for opportunistic infections during incarceration and after release would likely reduce mortality. Narcotic prisons may be especially high-risk environments for mortality, emphasizing the need for universal access to evidence-based HIV treatments.

Physician Decisions to Defer Antiretroviral Therapy in Key Populations: Implications for Reducing Human Immunodeficiency Virus Incidence and Mortality in Malaysia. Open Forum Infect Dis 2017; 4:ofw219. [PMID: 28480230 PMCID: PMC5414088 DOI: 10.1093/ofid/ofw219] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2016] [Accepted: 10/12/2016] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Antiretroviral therapy (ART) is recommended for all people living with human immunodeficiency virus (HIV), yet physician attitudes and prescribing behaviors toward members of key risk populations may limit ART access and undermine treatment as prevention strategies. METHODS Physicians in Malaysia (N = 214) who prescribe antiretroviral therapy (ART) responded in an Internet-based survey to hypothetical clinical scenarios of HIV patients, varying by key risk population and CD4+ T-cell count, on whether they would initiate or defer ART compared with a control patient with sexually acquired HIV. RESULTS The proportion of physicians who would defer ART in patients with advanced HIV (CD4 = 17 cells/μL) was significantly higher (P < .0001) for 4 key populations, including people who inject drugs ([PWID] 45.3%) or consume alcohol (42.1%), released prisoners (35.0%), and those lacking social support (26.6%), compared with a control patient (4.2%). People who inject drugs with advanced HIV (CD4 = 17 cells/μL) were 19-fold (adjusted odds ratio [AOR] = 18.9; 95% confidence interval [CI], 9.8-36.5) more likely to have ART deferred compared with the control. This effect was partially mitigated for PWID receiving methadone (AOR = 2.9; 95% CI, 1.5-5.7). At the highest CD4+ T-cell count (CD4 = 470 cells/μL), sex workers (AOR = 0.55; 95% CI, .44-.70) and patients with an HIV-uninfected sexual partner (AOR = 0.43; 95% CI, .34-.57) were significantly less likely to have ART deferred. CONCLUSIONS Physicians who prescribe antiretroviral therapy in Malaysia may defer ART in some key populations including PWID and released prisoners, regardless of CD4+ T-cell count, which may help to explain very low rates of ART coverage among PWID in Malaysia. Reducing HIV incidence and mortality in Malaysia, where HIV is concentrated in PWID and other key populations, requires clinician-level interventions and monitoring physician adherence to international evidence-based treatment guidelines.

Abstract
BACKGROUND Patients on opioid replacement therapy (ORT) to treat opioid use disorder are frequently monitored for these medications, but it is not known if they are also adhering to their psychotropic medications. This is an analysis of measure of potential adherence to psychotropic medications by patients on ORT. METHODS This is a retrospective cohort study of patients (n=1470) on antidepressants and/or antipsychotics and tested by the Millennium Health laboratory. Potential adherence to psychotropic medications was measured by urine drug test (UDT) results. The consistency of UDT for expected psychotropic medication in patients on ORT was compared to patients not on ORT (control group) during 3-months period. The study used propensity score methods to match individuals from both groups on their demographics and their psychotropic medication. RESULTS There were 457 participants (31.09%) on ORT and 1013 participants (68.91%) in the control group. Only 55.33% of UDTs (n=1388) were consistent for expected psychotropic medications in the ORT group compared to 73.69% of UDTs (n=4953) consistent for expected psychotropic medications in the control group (χ2=172.99, p<0.001). After matching, patients in the ORT group were less likely than the control group to have consistent UDTs for expected psychotropic medications (OR: 0.81, 95% CI: 0.76-0.85, P<0.001). CONCLUSION There is a high rate of inconsistent UDT for prescribed psychotropic medication among patients on ORT. This could reflect potential poor adherence. Monitoring adherence to psychotropic medications should be part of every clinical visit for patients on ORT.

Abstract
BACKGROUND Methadone maintenance therapy (MMT) is associated with improved HIV treatment outcomes among people who use drugs (PWUD). The extent to which these benefits are sustained in the context of ongoing cocaine use is unclear. We assessed differential impacts of MMT on HIV viral load (VL) suppression in relation to discrete patterns of cocaine use. METHODS Data was drawn from ACCESS, a prospective cohort of HIV-positive PWUD in Vancouver, Canada. Generalized linear mixed-effects were used to model the independent effect of MMT on VL suppression across strata of frequency of cocaine injection and crack smoking (≥daily versus <daily), after adjustment for confounders. RESULTS The analysis included 397 HIV-positive opioid users who completed ≥1 study interview between 2005 and 2014. At baseline, 304 (77%) reported participation in MMT, 37 (9%) ≥daily cocaine injection, and 158 (40%) ≥daily crack smoking. In adjusted analyses, MMT remained independently associated with increased odds of VL suppression in both strata of crack smokers (AOR=3.11, 95% CI: 1.86-5.21 and AOR=1.48, 95%CI: 1.04-2.09, for ≥daily and <daily smokers, respectively), and among <daily cocaine injectors (AOR=1.88, 95%CI 1.38-2.56), but not among ≥daily cocaine injectors (AOR=1.37, 95%CI 0.53-3.49). Longer retention on MMT was positively associated with VL suppression in all strata of cocaine injection and crack smoke. CONCLUSIONS Exposure to MMT was associated with increased odds of VL suppression among HIV- positive opioid users regardless of crack use. However, this beneficial effect of MMT was lost among frequent cocaine injectors with shorter retention on MMT.

Abstract
OBJECTIVES Certain prescribed opioids have immunosuppressive properties, yet their impact on clinically relevant outcomes, including antiretroviral therapy (ART) response among HIV-infected patients, remains understudied. METHODS Using the Veterans Aging Cohort Study data, we conducted a longitudinal analysis of 4358 HIV-infected patients initiating ART between 2002 and 2010 and then followed them for 24 months. The primary independent variable was prescribed opioid duration, categorized using pharmacy data as none prescribed, short-term (< 90 days) and long-term (≥ 90 days). Outcomes included CD4 cell count over time. Analyses adjusted for demographics, comorbid conditions, ART type and year of initiation, and overall disease severity [ascertained with the Veterans Aging Cohort Study (VACS) Index]. Sensitivity analyses examined whether effects varied according to baseline CD4 cell count, achievement of viral load suppression, and opioid properties (i.e. dose and known immunosuppressive properties). RESULTS Compared to those with none, patients with short-term opioids had a similar increase in CD4 cell count (mean rise per year: 74 vs. 68 cells/μL; P = 0.11), as did those with long-term prescribed opioids (mean rise per year: 74 vs. 75 cells/μL; P = 0.98). In sensitivity analysis, compared with no opioids, the effects of short-term prescribed opioids were statistically significant among those with a baseline CD4 cell count ≥ 500 cells/μL (mean rise per year: 52 cells/μL for no opioids vs. 20 cells/μL for short-term opioids; P = 0.04); findings were otherwise unchanged. CONCLUSIONS Despite immunosuppressive properties intrinsic to opioids, prescribed opioids appeared to have no effect on CD4 cell counts over 24 months among HIV-infected patients initiating ART.

Abstract
PURPOSE OF REVIEW The modern antiretroviral therapy (ART) era has seen substantial reductions in mortality among people living with HIV. However, HIV-positive people who inject drugs (PWIDs) continue to experience high rates of suboptimal HIV-related outcomes. We review recent findings regarding factors contributing to premature and preventable mortality among HIV-positive PWID, and describe the promise of interventions to improve survival in this group. RECENT FINDINGS The current leading causes of death among HIV-positive PWID are HIV/AIDS-related causes, overdose, and liver-related causes, including infection with hepatitis C virus. Elevated mortality levels in this population are driven by social-structural barriers to ART access and adherence, particularly criminalization and stigmatization of drug use. In contexts where opioid substitution therapy and ART adherence support programs are widely accessible, evidence highlights comparable levels of survival among HIV-positive PWID and people living with HIV who do not inject drugs. SUMMARY The life-saving benefits of ART can be realized among HIV-positive PWID when it is paired with strategies that address barriers to evidence-based medical care. Joint administration of ART and opioid substitution therapy, as well as repeal of punitive laws that criminalize drug users, are urgently needed to reduce HIV and injection-related mortality among PWID.

Abstract
AIMS To estimate the relationship between daily alcohol use and HIV seroconversion among people who inject drugs (PWID) in a Canadian setting. DESIGN AND SETTING Data from an open prospective cohort study of PWID in Vancouver, Canada, recruited via snowball sampling and street outreach between May 1996 and November 2013. An interviewer-administered questionnaire including standardized behavioural assessment and HIV antibody testing were conducted semi-annually. Baseline HIV-seronegative participants completing ≥ 1 follow-up visits were eligible for the present analysis. PARTICIPANTS A total of 1683 eligible participants, were followed for a median of 79.8 [interquartile range (IQR) = 33.3-119.1] months. MEASUREMENTS The primary end-point was time to HIV seroconversion, with the date of HIV seroconversion estimated as the mid-point between the last negative and the first positive antibody test results. The primary explanatory variable was self-reported daily alcohol use in the previous 6 months assessed semiannually. Other covariates considered included demographic, behavioural, social/structural and environmental risk factors for HIV infection among PWID (e.g. daily cocaine injection, methadone use, etc.). FINDINGS Of 1683 PWID, there were 176 HIV seroconversions during follow-up with an incidence density of 1.5 [95% confidence interval (CI) = 1.3-1.7] cases per 100 person-years. At baseline, 339 (20.1%) consumed alcohol at least daily in the previous 6 months. In multivariable extended Cox regression analyses, daily alcohol use remained associated independently with HIV seroconversion (adjusted hazard ratio: 1.48; 95% CI = 1.00-2.17). CONCLUSIONS Daily alcohol use appears to be an independent risk factor for HIV seroconversion among our cohort of PWID.

Abstract
Background People who inject drugs (PWID) living with HIV often experience sub-optimal antiretroviral therapy (ART) treatment outcomes, including HIV plasma viral load (PVL) rebound. While previous studies have identified risk factors for PVL rebound among PWID, no study has examined the perspectives of PWID who have experienced PVL rebound episodes. We conducted an ethno-epidemiological study to investigate the circumstances surrounding the emergence of rebound episodes among PWID in Vancouver, BC, Canada. Methods Comprehensive clinical records linked to a community-based prospective observational cohort of HIV-positive drug users were used to identify PWID who had recently experienced viral rebound. In-depth qualitative interviews with 16 male and 11 female participants explored participant perspectives regarding the emergence of viral rebound. A timeline depicting each participant’s HIV viral load and adherence to ART was used to elicit discussion of circumstances surrounding viral rebound. Findings Viral rebound episodes were shaped by interplay between various individual, social, and environmental factors that disrupted routines facilitating adherence. Structural-environmental influences resulting in non-adherence included housing transitions, changes in drug use patterns and intense drug scene involvement, and inadequate care for co-morbid health conditions. Social-environmental influences on ART adherence included poor interactions between care providers and patients producing non-adherence, and understandings of HIV treatment that fostered intentional treatment discontinuation. Conclusions This study describes key pathways which led to rebound episodes among PWID receiving ART and illustrates how environmental forces may increase vulnerability for non-adherence leading to treatment failure. Our findings have potential to help inform interventions and supports that address social-structural forces that foster non-adherence among PWID.

Abstract
Opioid use disorder is associated with significant health and social harms. Various evidence-based interventions have proven successful in mitigating these harms, including harm reduction strategies and pharmacological treatment such as methadone. We present a case of a 35-year-old HIV-positive woman who was off antiretroviral therapy due to untreated opioid use disorder, and had a history of frequently self-discharging from hospital against medical advice. During the most recent hospital admission, the patient was transferred to an innovative community-based clinical support residence that supported harm reduction. Initially, she received methadone to only manage the withdrawal symptoms rather than for long-term maintenance therapy. However, with gradual dose increases to treat cravings and withdrawal, she ultimately discontinued all drug use and reinitiated antiretroviral therapy. This case highlights that patients whose goal is not abstinence can be successfully treated for acute medical illnesses and comorbid substance use disorders using harm reduction approaches, including appropriate dosing of pharmacotherapy.

Abstract
In September 2015, the member states of the United Nations endorsed sustainable development goals (SDG) for 2030 that aspire to human rights-centered approaches to ensuring the health and well-being of all people. The SDGs embody both the UN Charter values of rights and justice for all and the responsibility of states to rely on the best scientific evidence as they seek to better humankind. In April 2016, these same states will consider control of illicit drugs, an area of social policy that has been fraught with controversy, seen as inconsistent with human rights norms, and for which scientific evidence and public health approaches have arguably played too limited a role. The previous UN General Assembly Special Session (UNGASS) on drugs in 1998 – convened under the theme “a drug-free world, we can do it!” – endorsed drug control policies based on the goal of prohibiting all use, possession, production, and trafficking of illicit drugs. This goal is enshrined in national law in many countries. In pronouncing drugs a “grave threat to the health and well-being of all mankind,” the 1998 UNGASS echoed the foundational 1961 convention of the international drug control regime, which justified eliminating the “evil” of drugs in the name of “the health and welfare of mankind.” But neither of these international agreements refers to the ways in which pursuing drug prohibition itself might affect public health. The “war on drugs” and “zero-tolerance” policies that grew out of the prohibitionist consensus are now being challenged on multiple fronts, including their health, human rights, and development impact. The Johns Hopkins – Lancet Commission on Drug Policy and Health has sought to examine the emerging scientific evidence on public health issues arising from drug control policy and to inform and encourage a central focus on public health evidence and outcomes in drug policy debates, such as the important deliberations of the 2016 UNGASS on drugs. The Johns Hopkins-Lancet Commission is concerned that drug policies are often colored by ideas about drug use and drug dependence that are not scientifically grounded. The 1998 UNGASS declaration, for example, like the UN drug conventions and many national drug laws, does not distinguish between drug use and drug abuse. A 2015 report by the UN High Commissioner for Human Rights, by contrast, found it important to emphasize that “[d]rug use is neither a medical condition nor does it necessarily lead to drug dependence.” The idea that all drug use is dangerous and evil has led to enforcement-heavy policies and has made it difficult to see potentially dangerous drugs in the same light as potentially dangerous foods, tobacco, alcohol for which the goal of social policy is to reduce potential harms.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2016; 31:25-31. [PMID: 26919826 DOI: 10.1016/j.drugpo.2016.01.022] [Citation(s) in RCA: 42] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2015] [Revised: 01/13/2016] [Accepted: 01/22/2016] [Indexed: 11/30/2022]
Abstract
Extra-medical prescription opioid (EMPO) use - intentional use without a prescription or outside of prescribed parameters - is a public health crisis in the United States and around the world. Epidemiological evidence suggests that the prevalence of EMPO use and adverse sequelae, including opioid overdose and hepatitis C infection, are elevated among people aged 18-25. Despite these preventable health risks, many harm reduction interventions are underutilized by, or inaccessible to, EMPO-using youth. In this commentary, we describe key harm reduction strategies for young people who use prescription opioids. We examine individual, social, and policy-level barriers to the implementation of evidence-based approaches that address EMPO use and related harms among young people. We highlight the need for expanded services and new interventions to engage this diverse and heterogeneous at-risk population. A combination of medical, social, and structural harm reduction interventions are recommended. Furthermore, research to inform strategies that mitigate particularly high-risk practices (e.g., polysubstance use) is warranted. Finally, we discuss how the meaningful involvement of youth in the implementation of harm reduction strategies is a critical component of the public health response to the prescription opioid epidemic.

Abstract
In many individuals, drug abuse is intimately linked with HIV-1 infection. In addition to being associated with one-third of all HIV-1 infections in the United States, drug abuse also plays a role in disease progression and severity in HIV-1-infected patients, including adverse effects on the central nervous system (CNS). Specific systems within the brain are known to be damaged in HIV-1-infected individuals and this damage is similar to that observed in drug abuse. Even in the era of anti-retroviral therapy (ART), CNS pathogenesis occurs with HIV-1 infection, with a broad range of cognitive impairment observed, collectively referred to as HIV-1-associated neurocognitive disorders (HAND). A number of HIV-1 proteins (Tat, gp120, Nef, Vpr) have been implicated in the etiology of pathogenesis and disease as a result of the biologic activity of the extracellular form of each of the proteins in a number of tissues, including the CNS, even in ART-suppressed patients. In this review, we have made Tat the center of attention for a number of reasons. First, it has been shown to be synthesized and secreted by HIV-1-infected cells in the CNS, despite the most effective suppression therapies available to date. Second, Tat has been shown to alter the functions of several host factors, disrupting the molecular and biochemical balance of numerous pathways contributing to cellular toxicity, dysfunction, and death. In addition, the advantages and disadvantages of ART suppression with regard to controlling the genesis and progression of neurocognitive impairment are currently under debate in the field and are yet to be fully determined. In this review, we discuss the individual and concerted contributions of HIV-1 Tat, drug abuse, and ART with respect to damage in the CNS, and how these factors contribute to the development of HAND in HIV-1-infected patients.
