Chiosi JJ, Mueller PP, Chhatwal J, Ciaranello AL. A multimorbidity model for estimating health outcomes from the syndemic of injection drug use and associated infections in the United States. BMC Health Serv Res 2023; 23:760. [PMID: 37461007 DOI: 10.1186/s12913-023-09773-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Accepted: 07/01/2023] [Indexed: 07/20/2023] Open
Abstract
BACKGROUND Fatal drug overdoses and serious injection-related infections are rising in the US. Multiple concurrent infections in people who inject drugs (PWID) exacerbate poor health outcomes, but little is known about how the synergy among infections compounds clinical outcomes and costs. Injection drug use (IDU) converges multiple epidemics into a syndemic in the US, including opioid use and HIV. Estimated rates of new injection-related infections in the US are limited due to widely varying estimates of the number of PWID in the US, and in the absence of clinical trials and nationally representative longitudinal observational studies of PWID, simulation models provide important insights to policymakers for informed decisions. METHODS We developed and validated a MultimorbiditY model to Reduce Infections Associated with Drug use (MYRIAD). This microsimulation model of drug use and associated infections (HIV, hepatitis C virus [HCV], and severe bacterial infections) uses inputs derived from published data to estimate national level trends in the US. We used Latin hypercube sampling to calibrate model output against published data from 2015 to 2019 for fatal opioid overdose rates. We internally validated the model for HIV and HCV incidence and bacterial infection hospitalization rates among PWID. We identified best fitting parameter sets that met pre-established goodness-of-fit targets using the Pearson's chi-square test. We externally validated the model by comparing model output to published fatal opioid overdose rates from 2020. RESULTS Out of 100 sample parameter sets for opioid use, the model produced 3 sets with well-fitting results to key calibration targets for fatal opioid overdose rates with Pearson's chi-square test ranging from 1.56E-5 to 2.65E-5, and 2 sets that met validation targets. The model produced well-fitting results within validation targets for HIV and HCV incidence and serious bacterial infection hospitalization rates. From 2015 to 2019, the model estimated 120,000 injection-related overdose deaths, 17,000 new HIV infections, and 144,000 new HCV infections among PWID. CONCLUSIONS This multimorbidity microsimulation model, populated with data from national surveillance data and published literature, accurately replicated fatal opioid overdose, incidence of HIV and HCV, and serious bacterial infections hospitalization rates. The MYRIAD model of IDU could be an important tool to assess clinical and economic outcomes related to IDU behavior and infections with serious morbidity and mortality for PWID.

Pharmacokinetic serum concentrations of VRC01 correlate with prevention of HIV-1 acquisition. EBioMedicine 2023; 93:104590. [PMID: 37300931 PMCID: PMC10363420 DOI: 10.1016/j.ebiom.2023.104590] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 04/06/2023] [Accepted: 04/12/2023] [Indexed: 06/12/2023] Open
Abstract
BACKGROUND The phase 2b proof-of-concept Antibody Mediated Prevention (AMP) trials showed that VRC01, an anti-HIV-1 broadly neutralising antibody (bnAb), prevented acquisition of HIV-1 sensitive to VRC01. To inform future study design and dosing regimen selection of candidate bnAbs, we investigated the association of VRC01 serum concentration with HIV-1 acquisition using AMP trial data. METHODS The case-control sample included 107 VRC01 recipients who acquired HIV-1 and 82 VRC01 recipients who remained without HIV-1 during the study. We measured VRC01 serum concentrations with a qualified pharmacokinetic (PK) Binding Antibody Multiplex Assay. We employed nonlinear mixed effects PK modelling to estimate daily-grid VRC01 concentrations. Cox regression models were used to assess the association of VRC01 concentration at exposure and baseline body weight, with the hazard of HIV-1 acquisition and prevention efficacy as a function of VRC01 concentration. We also compared fixed dosing vs. body weight-based dosing via simulations. FINDINGS Estimated VRC01 concentrations in VRC01 recipients without HIV-1 were higher than those in VRC01 recipients who acquired HIV-1. Body weight was inversely associated with HIV-1 acquisition among both placebo and VRC01 recipients but did not modify the prevention efficacy of VRC01. VRC01 concentration was inversely correlated with HIV-1 acquisition, and positively correlated with prevention efficacy of VRC01. Simulation studies suggest that fixed dosing may be comparable to weight-based dosing in overall predicted prevention efficacy. INTERPRETATION These findings suggest that bnAb serum concentration may be a useful marker for dosing regimen selection, and operationally efficient fixed dosing regimens could be considered for future trials of HIV-1 bnAbs.

Virally Suppressed People Living with HIV Who Use Opioids Have Diminished Latency Reversal. Viruses 2023; 15:415.

Abstract
Of the 12 million people who inject drugs worldwide, 13% live with HIV. Whether opioid use impacts HIV pathogenesis and latency is an outstanding question. To gain insight into whether opioid use influences the proviral landscape and latent HIV reservoir, we performed intact proviral DNA assays (IPDA) on peripheral blood mononuclear cells (PBMCs) from antiretroviral therapy (ART)-suppressed people living with HIV (PWH) with or without current opioid use. No differences were observed between PWH with and without opioid use in the frequency of HIV intact and defective proviral genomes. To evaluate the latent reservoir, we activated PBMCs from ART-suppressed PWH with or without opioid use and assessed the induction of HIV RNA. PWH using opioids had diminished responses to ex vivo HIV reactivation, suggesting a smaller reversible reservoir of HIV-1 latently infected cells. However, in vitro studies using primary CD4+ T cells treated with morphine showed no effect of opioids on HIV-1 infection, replication or latency establishment. The discrepancy in our results from in vitro and clinical samples suggests that while opioids may not directly impact HIV replication, latency and reactivation in CD4+ T cells, opioid use may indirectly shape the HIV reservoir in vivo by modulating general immune functions.

Escalated (Dependent) Oxycodone Self-Administration Is Associated with Cognitive Impairment and Transcriptional Evidence of Neurodegeneration in Human Immunodeficiency Virus (HIV) Transgenic Rats. Viruses 2022; 14:669. [PMID: 35458399 PMCID: PMC9030762 DOI: 10.3390/v14040669] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2022] [Revised: 03/02/2022] [Accepted: 03/09/2022] [Indexed: 02/05/2023] Open
Abstract
Substance use disorder is associated with accelerated disease progression in people with human immunodeficiency virus (HIV; PWH). Problem opioid use, including high-dose opioid therapy, prescription drug misuse, and opioid abuse, is high and increasing in the PWH population. Oxycodone is a broadly prescribed opioid in both the general population and PWH. Here, we allowed HIV transgenic (Tg) rats and wildtype (WT) littermates to intravenously self-administer oxycodone under short-access (ShA) conditions, which led to moderate, stable, "recreational"-like levels of drug intake, or under long-access (LgA) conditions, which led to escalated (dependent) drug intake. HIV Tg rats with histories of oxycodone self-administration under LgA conditions exhibited significant impairment in memory performance in the novel object recognition (NOR) paradigm. RNA-sequencing expression profiling of the medial prefrontal cortex (mPFC) in HIV Tg rats that self-administered oxycodone under ShA conditions exhibited greater transcriptional evidence of inflammation than WT rats that self-administered oxycodone under the same conditions. HIV Tg rats that self-administered oxycodone under LgA conditions exhibited transcriptional evidence of an increase in neuronal injury and neurodegeneration compared with WT rats under the same conditions. Gene expression analysis indicated that glucocorticoid-dependent adaptations contributed to the gene expression effects of oxycodone self-administration. Overall, the present results indicate that a history of opioid intake promotes neuroinflammation and glucocorticoid dysregulation, and excessive opioid intake is associated with neurotoxicity and cognitive impairment in HIV Tg rats.

Abstract
Drug abuse is a common comorbidity in people infected with HIV. HIV-infected individuals who abuse drugs are a key population who frequently experience suboptimal outcomes along the HIV continuum of care. A modest proportion of HIV-infected individuals develop HIV-associated neurocognitive issues, the severity of which further increases with drug abuse. Moreover, the tendency of the virus to go into latency in certain cellular reservoirs again complicates the elimination of HIV and HIV-associated illnesses. Antiretroviral therapy (ART) successfully decreased the overall viral load in infected people, yet it does not effectively eliminate the virus from all latent reservoirs. Although ART increased the life expectancy of infected individuals, it showed inconsistent improvement in CNS functioning, thus decreasing the quality of life. Research efforts have been dedicated to identifying common mechanisms through which HIV and drug abuse lead to neurotoxicity and CNS dysfunction. Therefore, in order to develop an effective treatment regimen to treat neurocognitive and related symptoms in HIV-infected patients, it is crucial to understand the involved mechanisms of neurotoxicity. Eventually, those mechanisms could lead the way to design and develop novel therapeutic strategies addressing both CNS HIV reservoir and illicit drug use by HIV patients.

Abstract
The United States and Canada are experiencing an opioid overdose crisis driven largely by exposure to fentanyl (a potent synthetic opioid), with little known about fentanyl exposure among HIV-positive people who use unregulated drugs (PWUD). We sought to estimate the prevalence and correlates of fentanyl exposure among a community-recruited sample derived from a prospective cohort study of HIV-positive PWUD in Vancouver, Canada. Generalized linear mixed-effects analyses were used to identify longitudinal factors associated with a fentanyl-positive urine drug screen test. Between June 2016-November 2017, 456 participants were recruited and contributed 1007 observations. At baseline, 96% of participants were ART-exposed, 72% had an HIV viral load (VL) <50 copies/mL and 21% had a fentanyl-positive test. Longitudinally, fentanyl-positive tests were characterized by: younger participant age (Adjusted Odds Ratio [AOR] = 0.45), recent non-fatal overdose (AOR = 2.30), engagement in opioid agonist therapy (AOR = 1.91), and at least daily heroin injection (AOR = 11.27). CD4+ cell count was negatively associated with fentanyl urine positivity (AOR = 0.92) (all p < 0.05). We identified several risk factors for overdose linked to fentanyl exposure among this sample, although no link with HIV treatment engagement or detectable HIV VL. Innovative strategies are needed to reduce the harmful effects of the contaminated unregulated drug supply experienced by PWUD.

[PMID: 34758887 PMCID: PMC8579672 DOI: 10.1186/s13722-021-00277-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2021] [Accepted: 11/01/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The CHOICES study randomized participants with HIV and opioid use disorder (OUD) to HIV clinic-based extended-release naltrexone (XR-NTX), which requires complete cessation of opioid use, versus treatment-as-usual (i.e., buprenorphine, methadone). Study participants randomized to XR-NTX were interviewed to assess their experiences with successful and unsuccessful XR-NTX induction. METHODS Semi-structured qualitative interviews were completed with a convenience sample of study participants with HIV and OUD (n = 37) randomized to XR-NTX in five HIV clinics between 2018 and 2019. All participants approached agreed to be interviewed. Interviews were digitally recorded, professionally transcribed, and analyzed using thematic analysis. RESULTS Participants included women (43%), African Americans (62%) and Hispanics (16%), between 27 to 69 years of age. Individuals who completed XR-NTX induction (n = 20) reported experiencing (1) readiness for change, (2) a supportive environment during withdrawal including comfort medications, and (3) caring interactions with staff. Four contrasting themes emerged among participants (n = 17) who did not complete induction: (1) concern and anxiety about withdrawal including past negative experiences, (2) ambivalence about or reluctance to stop opioids, (3) concerns about XR-NTX effects, and (4) preferences for other medications. CONCLUSIONS The results highlight opportunities to improve initiation of XR-NTX in high-need groups. Addressing expectations regarding induction may enhance XR-NTX initiation rates.

Assessing combinatorial effects of HIV infection and former cocaine dependence on cognitive control processes: A high-density electrical mapping study of response inhibition. Neuropharmacology 2021; 195:108636.

Abstract
Stimulant drug use in HIV + patients is associated with poor personal and public health outcomes, including high-risk sexual behavior and faster progression from HIV to AIDS. Inhibitory control--the ability to withhold a thought, feeling, or action--is a central construct involved in the minimization of risk-taking behaviors. Recent neuroimaging and behavioral evidence indicate normalization of inhibitory control processes in former cocaine users as a function of the duration of drug abstinence, but it is unknown whether this recovery trajectory persists in former users with comorbid HIV. Here, we investigate the neural correlates of inhibitory control in 103 human subjects using high-density EEG recording as participants performed a Go/NoGo response inhibition task. Four groups of participants were recruited, varying on HIV and cocaine-dependence status. Electrophysiological responses to successful inhibitions and behavioral task performance were compared among groups. Results indicate persistent behavioral and neurophysiological impairment in HIV+ patients' response inhibition despite current abstinence from cocaine. Analysis of task performance showed that HIV+ abstinent cocaine-dependent participants demonstrate the lowest performance of all groups across all metrics of task accuracy. Planned comparisons of electrophysiological components revealed a main effect of scalp site and an interaction between HIV-status and scalp site on N2 amplitudes during successful inhibitions. Analysis of the P3 time region showed a main effect of scalp site and an interaction between HIV-status and cocaine dependence. These results suggest synergistic alterations in the neurophysiology of response inhibition and indicate that abstinence-related recovery of inhibitory control may be attenuated in patients with HIV.

Abstract
Psychostimulant use is a major comorbidity in people living with HIV, which was initially explained by them adopting risky behaviors that facilitate HIV transmission. However, the effects of drug use on the immune system might also influence this phenomenon. Psychostimulants act on peripheral immune cells even before they reach the central nervous system (CNS) and their effects on immunity are likely to influence HIV infection. Beyond their canonical activities, classic neurotransmitters and neuromodulators are expressed by peripheral immune cells (e.g., dopamine and enkephalins), which display immunomodulatory properties and could be influenced by psychostimulants. Immune receptors, like Toll-like receptors (TLRs) on microglia, are modulated by cocaine and amphetamine exposure. Since peripheral immunocytes also express TLRs, they may be similarly affected by psychostimulants. In this review, we will summarize how psychostimulants are currently thought to influence peripheral immunity, mainly focusing on catecholamines, enkephalins and TLR4, and shed light on how these drugs might affect HIV infection. We will try to shift from the classic CNS perspective and adopt a more holistic view, addressing the potential impact of psychostimulants on the peripheral immune system and how their systemic effects could influence HIV infection.

Abstract
BACKGROUND People living with HIV who report substance use (PLWH-SU) face many barriers to care, resulting in an increased risk for poor health outcomes and the potential for ongoing disease transmission. This study evaluates the mechanisms by which Patient Navigation (PN) and Contingency Management (CM) interventions may work to address barriers to care and improve HIV outcomes in this population. METHODS Mediation analysis was conducted using data from a randomized, multi-site trial testing PN interventions to improve HIV care outcomes among 801 hospitalized PLHW-SU. Direct and indirect effects of PN and PN + CM were evaluated through five potential mediators-psychosocial conditions, healthcare avoidance, financial hardship, system barriers, and self-efficacy for HIV treatment adherence-on engagement in HIV care and viral suppression. RESULTS The PN + CM intervention had an indirect effect on improving engagement in HIV care at 6 months by increasing self-efficacy for HIV treatment adherence (β = 0.042, 95% CI = 0.008, 0.086). PN + CM also led to increases in viral suppression at 6 months (β = 0.090, 95% CI = 0.023, 0.168) and 12 months (β = 0.069, 95% CI = 0.009, 0.129) via increases in self-efficacy, although the direct effects were not significant. No mediating effects were observed for PN alone. CONCLUSION PN + CM interventions for PLWH-SU can increase an individual's self-efficacy for HIV treatment adherence, which in turn improves engagement in care at 6 months and may contribute to viral suppression over 12 months. Building self-efficacy may be a key factor in the success of such interventions and should be considered as a primary goal of PN + CM in practice.

Abstract
In the era of combined antiretroviral therapy (cART), human immunodeficiency virus type 1 (HIV-1) is considered a chronic disease with an inflammatory component that specifically targets the brain and causes a high prevalence of HIV-1-associated neurocognitive disorders (HAND). The endocannabinoid (eCB) system has attracted interest as a target for treatment of neurodegenerative disorders, due to the potential anti-inflammatory and neuroprotective properties of cannabinoids, including its potential therapeutic use in HIV-1 neuropathogenesis. In this review, we summarize what is currently known about the structural and functional changes of the eCB system under conditions of HAND. This will be followed by summarizing the current clinical and preclinical findings on the effects of cannabis use and cannabinoids in the context of HIV-1 infection, with specifically focusing on viral load, cognition, inflammation, and neuroprotection. Lastly, we present some potential future directions to better understand the involvement of the eCB system and the role that cannabis use and cannabinoids play in neuroHIV.

Abstract
Antiretroviral therapy (ART) has transformed HIV into a chronic condition, lengthening and improving the lives of individuals living with this virus. Despite successful suppression of HIV replication, people living with HIV (PLWH) are susceptible to a growing number of comorbidities, including neuroHIV that results from infection of the central nervous system (CNS). Alterations in the dopaminergic system have long been associated with HIV infection of the CNS. Studies indicate that changes in dopamine concentrations not only alter neurotransmission, but also significantly impact the function of immune cells, contributing to neuroinflammation and neuronal dysfunction. Monocytes/macrophages, which are a major target for HIV in the CNS, are responsive to dopamine. Therefore, defining more precisely the mechanisms by which dopamine acts on these cells, and the changes in cellular function elicited by this neurotransmitter are necessary to develop therapeutic strategies to treat neuroHIV. This is especially important for vulnerable populations of PLWH with chemically altered dopamine concentrations, such as individuals with substance use disorder (SUD), or aging individuals using dopamine-altering medications. The specific neuropathologic and neurocognitive consequences of increased CNS dopamine remain unclear. This is due to the complex nature of HIV neuropathogenesis, and logistical and technical challenges that contribute to inconsistencies among cohort studies, animal models and in vitro studies, as well as lack of demographic data and access to human CNS samples and cells. This review summarizes current understanding of the impact of dopamine on HIV neuropathogenesis, and proposes new experimental approaches to examine the role of dopamine in CNS HIV infection. Graphical abstract HIV Neuropathogenesis in the Presence of a Disrupted Dopamine System. Both substance abuse disorders and the use of dopaminergic medications for age-related diseases are associated with changes in CNS dopamine concentrations and dopaminergic neurotransmission. These changes can lead to aberrant immune function, particularly in myeloid cells, which contributes to the neuroinflammation, neuropathology and dysfunctional neurotransmission observed in dopamine-rich regions in HIV+ individuals. These changes, which are seen despite the use antiretroviral therapy (ART), in turn lead to further dysregulation of the dopamine system. Thus, in individuals with elevated dopamine, the bi-directional interaction between aberrant dopaminergic neurotransmission and HIV infection creates a feedback loop contributing to HIV associated neurocognitive dysfunction and neuroHIV. However, the distinct contributions and interactions made by HIV infection, inflammatory mediators, ART, drugs of abuse, and age-related therapeutics are poorly understood. Defining more precisely the mechanisms by which these factors influence the development of neurological disease is critical to addressing the continued presence of neuroHIV in vulnerable populations, such as HIV-infected older adults or drug abusers. Due to the complexity of this system, understanding these effects will require a combination of novel experimental modalities in the context of ART. These will include more rigorous epidemiological studies, relevant animal models, and in vitro cellular and molecular mechanistic analysis.

Abstract
People living with HIV (PLWH) who use drugs experience worse health outcomes than their non-using counterparts. Little is known about how often they seek dental care and the factors that influence their utilization. PLWH with substance use disorders who were inpatients at 11 urban hospitals (n = 801) participated in a National Institute on Drug Abuse Clinical Trials Network study to improve engagement in HIV outcomes. Dental care utilization at each time point during the study period (baseline, 6 months and/or 12 months) was assessed (n = 657). Univariate analysis and logistic regression were used to examine factors associated with dental care utilization. Over half (59.4%) reported not having received any dental care at any timepoint. Participants with less than high school education had lower odds of reporting dental care utilization than those with more than education (aOR = 0.60 [95% CI 0.37-0.99], p = 0.0382). Participants without health insurance also had lower odds of reporting dental care utilization than those with insurance (aOR = 0.50 [95% CI 0.331-0.76], p = 0.0012). Higher food insecurity was associated with having recent dental care utilization (OR = 1.03 [95% CI 1.00, 1.05], p = 0.0359). Additionally, those from Southern states were less likely to report dental care utilization (aOR = 0.55 [95% CI 0.38, 0.79], p = 0.0013). Having health insurance and education are key factors associated with use of dental care for PLWH with substance use disorders. The association between food insecurity and dental care utilization among this population suggests the need for further exploration.

Abstract
OBJECTIVES HIV-positive people who use illicit drugs (PWUD) experience elevated rates of HIV-associated morbidity and mortality compared with members of other key affected populations. Although suboptimal levels of access and adherence to antiretroviral therapy (ART) are common among HIV-positive PWUD, there is a need for studies investigating the possible biological impacts of noninjection illicit drug use among people living with HIV in real-world settings. METHODS We accessed data from the ACCESS study, an ongoing prospective cohort of illicit drug users with systematic HIV viral load monitoring in a setting with universal care and ART dispensation records. We used multivariable generalized linear mixed models to estimate the longitudinal associations between noninjection use of crack cocaine, powder cocaine, opioids, methamphetamine, cannabis and alcohol on plasma HIV-1 RNA viral load, adjusted for ART exposure and relevant confounders. RESULTS Between 2005 and 2018, 843 individuals from the ACCESS cohort were included and contributed to 8698 interviews. At baseline, the mean age was 43 years, 566 (67%) reported male sex and 659 (78%) used crack cocaine in the previous 6 months. In multivariable models adjusted for ART exposure, only crack cocaine use in the last 6 months was found to be significantly associated with higher HIV viral load. CONCLUSION We observed significantly higher HIV viral load during periods of crack cocaine use independent of ART exposure. Our findings support further research to investigate the possible biological mechanisms of this effect.

Abstract
Opioid abuse alters the functions of immune cells in both in vitro and in vivo systems, including macrophages. Here, we investigated the effects of methadone, a widely used opioid receptor agonist for treatment of opiate addiction, on the expression of intracellular viral restriction factors and HIV replication in primary human macrophages. We showed that methadone enhanced the HIV infectivity in primary human macrophages. Mechanistically, methadone treatment of macrophages reduced the expression of interferons (IFN-β and IFN-λ2) and the IFN-stimulated anti-HIV genes (APOBEC3F/G and MxB). In addition, methadone-treated macrophages showed lower levels of several anti-HIV microRNAs (miRNA-28, miR-125b, miR-150, and miR-155) compared to untreated cells. Exogenous IFN-β treatment restored the methadone-induced reduction in the expression of the above genes. These effects of methadone on HIV and the antiviral factors were antagonized by pretreatment of cells with naltrexone. These findings provide additional evidence to support further studies on the role of opiates, including methadone, in the immunopathogenesis of HIV disease.

Abstract
Cannabis use is prevalent among HIV-positive persons, but evidence regarding the impact of cannabis in HIV-positive persons is limited. We conducted a retrospective cohort study of HIV-positive adults initiating their first antiretroviral therapy (ART) regimen. A dedicated intake form assessed self-reported cannabis use in the preceding 7 days at each visit. The relationships between time-varying cannabis use and body mass index (BMI), CD4+ T-cell count, and HIV-1 RNA levels were assessed using random effects models adjusted for age, sex, race, and other reported substance use. 4290 patient-visits from 2008 to 2011 were available from 1010 patients. Overall, there were no statistically significant differences in CD4+ T-cell count and BMI across multiple adjusted models using different measures of cannabis use (ever use during the study period, any use, and number of times used in the preceding 7 days). Cannabis use by all three measures was associated with greater odds of having a detectable viral load at a given visit than no reported use (OR 2.02, 1.72, and 1.08, respectively; all adjusted p < 0.05). Self-reported cannabis use was not associated with changes in BMI or CD4+ T-cell count in ART-naïve HIV-positive persons starting treatment. However, reported cannabis use by multiple categories was associated with having a detectable HIV-1 RNA during the study period. Associations between cannabis use, adherence, and HIV-related outcomes merit further study.

Abstract
BACKGROUND Active illicit drug use can present a barrier to the medical management of HIV infection by complicating adherence to antiretroviral therapy (ART). Plasma HIV-1 RNA viral load (VL) rebound, defined as a period of detectable HIV VL following ART and VL suppression, can lead to the generation of viral resistance and potential treatment failure. We sought to investigate the contribution of substance use patterns on rates of VL rebound. METHODS We used data from the ACCESS study, a long-running community-recruited prospective cohort of HIV-positive people who use illicit drugs in Vancouver, Canada, a setting of universal no-cost HIV treatment. We analysed time to VL rebound (that is, two consecutive observations ≥1,000 copies/ml) after ART initiation and sustained viral suppression (that is, two consecutive observations <50 copies/ml) using extended Cox regression models with a recurrent events framework. RESULTS Between May 1996 and November 2013, 564 ART-exposed participants achieved at least one instance of VL suppression and contributed 1,893.8 person-years of observation. Over follow-up, 198 (35.1%) participants experienced ≥ one instance of VL rebound. In adjusted analyses, VL rebound was associated with younger age (adjusted hazard ratio [AHR] =0.97, 95% CI: 0.95, 0.98), heroin injection (≥ daily versus < daily, AHR =1.52, 95% CI: 1.01, 2.30), crack use (≥ daily versus < daily, AHR = 1.73, 95% CI: 1.08, 1.92) and heavy alcohol use (≥ four versus < four drinks/day, AHR =1.97, 95% CI: 1.17, 3.31). CONCLUSIONS The present study suggests that in addition to heavy alcohol use, high-intensity illicit drug use, particularly ≥ daily heroin injection and ≥ daily crack smoking are risk factors for VL rebound. In addition to the impact of high-intensity drug use on health-care engagement and ART adherence, some evidence exists on the direct impact of psychoactive substances on ART metabolism and the natural progression of HIV disease. At-risk individuals should be provided additional supports to preserve virological control and maintain the benefits of ART.

Abstract
The abuse of stimulants, such as methamphetamine (METH), is associated with treatment non-compliance, a greater risk of viral transmission, and the more rapid clinical progression of immunological and central nervous system human immunodeficiency virus (HIV) disease. The behavioral effects of METH in the setting of HIV remain largely uncharacterized. We used a state-of-the-art paradigm of the escalation of voluntary intravenous drug self-administration in HIV transgenic (Tg) and wildtype rats. The rats were first allowed to self-administer METH under short-access (ShA) conditions, which is characterized by a nondependent and more "recreational" pattern of METH use, and then allowed to self-administer METH under long-access (LgA) conditions, which leads to compulsive (dependent) METH intake. HIV Tg and wildtype rats self-administered equal amounts of METH under ShA conditions. HIV Tg rats self-administered METH under LgA conditions following a 4-week enforced abstinence period to model the intermittent pattern of stimulant abuse in humans. These HIV Tg rats developed greater motivation to self-administer METH and self-administered larger amounts of METH. Impairments in function of the medial prefrontal cortex (mPFC) contribute to compulsive drug and alcohol intake. Gene expression profiling of the mPFC in HIV Tg rats with a history of escalated METH self-administration under LgA conditions showed transcriptional evidence of increased inflammation, greater neural injury, and impaired aerobic glucose metabolism than wildtype rats that self-administered METH under LgA conditions. The detrimental effects of the interaction between neuroHIV and escalated METH intake on the mPFC are likely key factors in the greater vulnerability to excessive drug intake in the setting of HIV.

Barriers and facilitators to recruitment and enrollment of HIV-infected individuals with opioid use disorder in a clinical trial. BMC Health Serv Res 2019; 19:862.

Abstract
BACKGROUND The CTN-0067 CHOICES trial tests implementation of extended-release naltrexone (XR-NTX) versus treatment-as-usual (TAU) for opioid use disorders (OUD) in HIV clinics to improve HIV viral suppression. The study team investigated recruitment strategies to elucidate the barriers and facilitators to recruitment and enrollment in the study. MAIN TEXT Methods: Semi-structured, in-depth, digitally recorded interviews were completed with study recruitment-related staff and medical providers (n = 26) from six participating HIV clinics in the fall of 2018. Interviews probed 1) factors that might prevent prospective participants from engaging in study recruitment and enrollment procedures and 2) strategies used by study staff that encourage eligible patient participation. Interviews were transcribed and thematically analyzed using a content analysis approach. RESULTS All respondents reported that barriers to recruitment and enrollment included challenging patient social and structural factors (e.g., homelessness or living environments with high substance use, criminal justice involvement), difficulty locating patients with unsuppressed HIV viral load and OUD within the HIV clinic, time-consuming study enrollment processes, and stigma around HIV and OUD which inhibited treatment seeking. Some respondents observed that distrust of research and researchers impeded recruitment activities in the community. A specific medication-related barrier was patient fear of opioid abstinence required prior to XR-NTX induction. Facilitators of recruitment included use of trusted peer outreach/recruitment workers in the community, hospitalizations that offered windows of opportunities for screening and XR-NTX induction, providing participant transportation, and partnerships with harm reduction organizations for referrals. CONCLUSIONS Though study personnel encountered barriers to recruitment in the CHOICES study, persons with untreated HIV and OUD can be enrolled in multisite clinical trials by using enhanced recruitment strategies that extend outside of the HIV clinic. Employing peer outreach workers and collaborating with syringe service programs may be especially helpful in facilitating recruitment and merit inclusion in similar study protocols.

Abstract
The brain is particularly sensitive to changes in energy supply. Defects in glucose utilization and mitochondrial dysfunction are hallmarks of nearly all neurodegenerative diseases and are also associated with the cognitive decline that occurs as the brain ages. Chronic neuroinflammation driven by glial activation is commonly implicated as a contributing factor to neurodegeneration and cognitive impairment. Human immunodeficiency virus-1 (HIV-1) disrupts normal brain homeostasis and leads to a spectrum of HIV-associated neurocognitive disorders (HAND). HIV-1 activates stress responses in the brain and triggers a state of chronic neuroinflammation. Growing evidence suggests that inflammatory processes and bioenergetics are interconnected in the propagation of neuronal dysfunction. Clinical studies of people living with HIV and basic research support the notion that HIV-1 creates an environment in the CNS that interrupts normal metabolic processes at the cellular level to collectively alter whole brain metabolism. In this review, we highlight reports of abnormal brain metabolism from clinical studies and animal models of HIV-1. We also describe diverse CNS cell-specific changes in bioenergetics associated with HIV-1. Moreover, we propose that attention should be given to adjunctive therapies that combat sources of metabolic dysfunction as a mean to improve and/or prevent neurocognitive impairments.

Abstract
OBJECTIVES Antiretroviral therapy is affording longer lifespans for people living with HIV (PLWH), yet factors such as substance use play an increasing role in morbidity and mortality in this population. Though previous studies have examined substance use differences between age cohorts of PLWH, no study has examined the influence of birth cohort on current substance use patterns. Thus, this study investigated the prevalence of past 12-month self-reported substance use between four birth cohorts, <1970 (M age = 54.1), 1970s (M age = 41.5), 1980s (M age = 31.3 years old), and 1990s (M age = 23.2 years old) of PLWH in Florida. METHODS PLWH (N = 934) recruited from community health clinics in Florida completed a questionnaire assessing sociodemographics, health status, and substance use. Multivariate logistic regressions utilizing the <1970 cohort as the referent group examined the relationship between birth cohort and substance use. RESULTS The 1980s cohort had significantly greater odds of marijuana use compared to the oldest cohort (<1970s), while the three younger cohorts (1970s, 1980s, and 1990s) evidenced a significantly greater odds of ecstasy use compared to the oldest group. Contrastingly, the three younger birth cohorts reported significantly less crack use than the oldest cohort, while the youngest group (1990s) also demonstrated an 80% reduction in injection drug use compared to the oldest group. CONCLUSION The older cohort evidenced significantly greater crack and injection drug use, while the younger cohorts evidenced greater marijuana and ecstasy use. Therefore, it is important to develop age-specific substance use interventions among PLWH.

Abstract
BACKGROUND Drug use (DU) represents a significant barrier to maintaining physical health among people living with HIV (PLWH). Few studies, however, have examined the relationship between DU over time and HIV treatment outcomes. Such studies are needed because an individual's risk of poor health outcomes may vary with their DU behaviors. We examined associations between DU patterns over time and unsuppressed viral load (VL). METHODS The sample included 7896 PLWH in New York City who completed ≥3 substance use assessments over a 24-month period. DU was defined as crystal methamphetamine, crack/cocaine, heroin, and/or recreational prescription medication use in the last three months. Four behavior patterns were constructed: (1) persistent use (DU reported on each assessment); (2) intermittent use-active (DU reported on the third, but not all previous assessments); (3) intermittent use-inactive (DU reported previously with no DU reported on the third assessment); (4) persistent non-use (no DU reported on any assessment). Unsuppressed VL (>200 copies/mL) was assessed based on the last VL value in the New York City HIV Surveillance Registry in the 12 months following an individual's third DU assessment. RESULTS Compared with persistent non-users, individuals with intermittent use-inactive (aOR = 1.24, 95% CI = 1.03-1.49), intermittent use-active (aOR = 1.68, 95% CI = 1.36-2.06), and persistent use (aOR = 2.21, 95% CI = 1.69-2.89) were significantly more likely to have unsuppressed VL. CONCLUSIONS While providers may be more likely to intervene with persistent or active drug users, our findings suggest the importance of addressing the risk of poor HIV treatment outcomes among those with any DU behavior.

Abstract
Using baseline data from the NIDA Clinical Trials Network 0049 study (Project HOPE), we performed latent class analyses (LCA) to identify discrete classes, or clusters, of people living with HIV (PLWH) based on their past year substance use behaviors and lifetime arrest history. We also performed multinomial logistic regressions to identify key characteristics associated with class membership. We identified 5 classes of substance users (minimal drug users, cocaine users, substantial cocaine/hazardous alcohol users, problem polysubstance users, substantial cocaine/heroin users) and 3 classes of arrest history (minimal arrests, non-drug arrests, drug-related arrests). While several demographic variables such as age and being Black or Hispanic were associated with class membership for some of the latent classes, participation in substance use treatment was the only covariate that was significantly associated with membership in all classes in both substance use and arrest history LCA models. Our analyses reveal complex patterns of behaviors among substance using PLWH and suggest that HIV intervention strategies may need to take into consideration such nuanced differences to better inform future studies and program implementation.

Abstract
Accurate, routine measurement of recent illicit substance use is challenging. The Johns Hopkins Human Immunodeficiency Virus Clinical Cohort (Baltimore, Maryland) collects 2 imperfect but routine measurements of recent substance use: medical record review and self-interview. We used Bayesian latent class modeling to estimate sensitivity and specificity of each measurement as well as prevalence of substance use among 2,064 patients engaged in care during 2007-2015. Sensitivity of medical record review was higher than sensitivity of self-interview for cocaine and heroin use; posterior estimates ranged from 44% to 76% for cocaine use and from 39% to 67% for heroin use, depending on model assumptions and priors. In contrast, sensitivity of self-interview was higher than sensitivity of medical record review for any alcohol use, hazardous alcohol use, and cigarette smoking. Posterior estimates of sensitivity of self-interview were generally above 80%, 85%, and 87% for each substance, respectively. Specificity was high for all measurements. From one model, we estimated prevalence of substance use in the cohort to be 12.5% for cocaine, 9.3% for heroin, 48.5% for alcohol, 21.4% for hazardous alcohol, and 55.4% for cigarettes. Prevalence estimates from other models were generally comparable. Measurement error of substance use is nontrivial and should be accounted for in subsequent analyses.

Abstract
Determining the barriers and facilitators of antiretroviral adherence among former and current substance users may be useful in the creation of successful interventions that target this hard-to-reach population. We performed a cross-sectional study of HIV-infected patients (N = 123) prescribed antiretroviral therapy at four Chicago healthcare venues. Bivariate and multivariable analyses were performed to determine factors associated with non-adherence based on definitions of non-adherence (any missed doses) within the past 4-day, 14-day, and 1-month time periods. Factors consistently associated with non-adherence in bivariate and multivariate analyses, regardless of duration of non-adherence definition, were lower confidence in taking medication consistently and less self-reported ability to read. These data reveal the importance of self-efficacy and ability to read (rather than specific knowledge of CD4 and viral load definitions) in the design of interventions in a population of HIV-infected persons with significant substance use.

Abstract
Among persons living with HIV/AIDS (PLHIV), approximately two-thirds report moderate to severe pain. Chronic pain can negatively affect PLHIVs' health behaviors and outcomes by interfering with their reciprocity (mutual exchange) of support in their caregiving relationships, which has been found to be associated with PLHIVs' antiretroviral adherence and viral suppression. Data were longitudinal (baseline, 6- and 12-month follow-up) from 383 PLHIV who were formerly or currently using drugs. Utilizing a longitudinal lagged fixed effects structural equation model, we found that never having pain in the past 6 months was predictive of increased reciprocity of support. Sub-analyses by care relationship type revealed never having pain was a significant predictor of greater reciprocity for sexual partner caregiving dyads, but not for kin or friend caregiving dyads. Our study emphasizes the importance of pain management in quality caregiving relationships characterized by reciprocity, which has consistently been found to be associated with stronger, more supportive caregiving relationships and better quality of life. Our findings suggest the importance of pain management intervention for improving reciprocity between vulnerable PLHIVs and their primary caregivers, especially between PLHIVs and caregivers who are current or former sexual partners.

Abstract
We aimed to determine the prevalence of drug and polydrug use in people living with HIV in Austria for the first time for which a two center cross-sectional study was performed. Participants were recruited from consecutive patients during their regularly scheduled visits. In total 438 participants were included in the analysis. For this study we used paper-pencil and online-based questionnaires. The prevalence of illicit drug use was 60.5%; with cannabis use at 31.5%, nitrates at 31.5%, sildenafil/tadalafil at 24% and cocaine at 14%, being the most used substances. Use of more than one substance (polydrug) in drug users was 69.4% or 42.0% in the total study population. Younger age, male gender, and living in an urban area were associated with drug use. Moreover, drug use during clubbing and sex, HIV therapy non-adherence and younger age were associated with polydrug use. Drug users reported condomless sex in 42.4% and performing sexual acts they would not do sober in 44.1%. Results indicate a high prevalence of illicit drug use in PLWHIV in Austria. New research focusing on illicit drug use in PLWHIV should focus on the use of substances during sex and surrounding practices.

Abstract
The success of anti-retroviral therapy has improved the quality of life and lifespan of HIV + individuals, transforming HIV infection into a chronic condition. These improvements have come with a cost, as chronic HIV infection and long-term therapy have resulted in the emergence of a number of new pathologies. This includes a variety of the neuropathological and neurocognitive effects collectively known as HIVassociated neurocognitive disorders (HAND) or NeuroHIV. These effects persist even in the absence of viral replication, suggesting that they are mediated the long-term changes in the CNS induced by HIV infection rather than by active replication. Among these effects are significant changes in catecholaminergic neurotransmission, especially in dopaminergic brain regions. In HIV-infected individuals not treated with ARV show prominent neuropathology is common in dopamine-rich brain regions and altered autonomic nervous system activity. Even infected individuals on therapy, there is significant dopaminergic neuropathology, and elevated stress and norepinephrine levels correlate with a decreased effectiveness of antiretroviral drugs. As catecholamines function as immunomodulatory factors, the resultant dysregulation of catecholaminergic tone could substantially alter the development of HIVassociated neuroinflammation and neuropathology. In this review, we discuss the role of catecholamines in the etiology of HIV neuropathogenesis. Providing a comprehensive examination of what is known about these molecules in the context of HIV-associated disease demonstrates the importance of further studies in this area, and may open the door to new therapeutic strategies that specifically ameliorate the effects of catecholaminergic dysregulation on NeuroHIV.

Abstract
BACKGROUND While in its early years the HIV epidemic affected primarily the male and the young, nowadays, the population living with HIV/AIDS is approximately 24% women, and its age composition has shifted towards older ages. Many of the older women who live with HIV/AIDS also live with the medical and social conditions that accompany aging. This work aims to identify and characterize empirical studies of strategies for the comprehensive management of women over 40, including transgender women, who live with HIV/AIDS. Forty was chosen as an operational age cutoff to identify premenopausal women who are less likely to bear children, as well as peri- and postmenopausal women. METHODS We conducted a literature search after discussions with a diverse panel of content experts and other stakeholders and developed an evidence map that identified 890 citations that address questions having to do with programs and barriers to engaging with programs, as well as the role of insurance and comorbidities, and have enrolled older women who live with HIV/AIDS. RESULTS Of these, only 37 (4%) reported results of interest for women over 40 who live with HIV/AIDS, or examined interactions between gender and older age that would allow predictions in this subgroup. Few of the 37 eligible studies focused on women facing obvious challenges, such as immigrants, transgender, physically abused, or those recently released from prison. No studies focused on women caring for dependents, including children and grandchildren, or those diagnosed after age 40. CONCLUSION The evidence base that is directly applicable to women over 40 who live with HIV/AIDS in the USA is limited, and the research need is broad. We propose research prioritization strategies for this population.

Abstract
BACKGROUND Substance use among HIV-positive persons exacerbates health problems. This study sought to estimate the prevalence of alcohol and drug-use diagnoses and examined hypothesized predictors associated with alcohol and drug-use diagnoses among HIV-positive patients in New York City (NYC). METHODS This cohort study reviewed electronic medical records (EMRs) of 4965 HIV-positive patients based on diagnostic codes. These patients attended a comprehensive care clinic in NYC in 2012. Multinomial logistic regression was used to predict the odds of classification into substance use diagnosis grouping. RESULTS Of the full sample, only 12.7% of patients had an alcohol use diagnosis documented in their EMR compared with more than one-quarter (26.4%) of patients having a recorded drug use diagnosis (p<0.001). Compared with the No Alcohol or Drugs group, the regression model showed that older age and having a recent inpatient hospital stay independently predicted being in the Alcohol Only group; years living with HIV, having an unsuppressed viral load, and having a recent inpatient hospital stay were associated with higher odds of being in the Drugs Only and Alcohol and Drugs groups; and being women and men who have sex with men (MSM) were associated with decreased odds of being in the Drugs Only and Alcohol and Drugs groups. CONCLUSIONS Substance use diagnosis was associated with viremia and low CD4 counts and hospital stays. This implies that providers should screen for substance use in HIV-positive patients with poor health. Further examination of the extent of such comorbidity is instrumental for intervention efforts.

Abstract
BACKGROUND Contemporary studies about HIV care continuum (HCC) outcomes within substance using populations primarily focus on individual risk factors rather than provider- or systems-level influences. Over 25% of people living with HIV (PLWH) have substance use disorders that can alter their path through the HCC. As part of a study of HCC outcomes in nine small cities in Southern New England (population 100,000-200,000 and relatively high HIV prevalence particularly among substance users), this qualitative analysis sought to understand public health staff and HIV service providers' perspectives on how substance use may influence HCC outcomes. METHODS Interviews with 49 participants, collected between November 2015 and June 2016, were analyzed thematically using a modified social ecological model as the conceptual framework and codes for substance use, HCC barriers and facilitators, successes and failures of initiatives targeting the HCC, and criminal justice issues. RESULTS Eight themes were identified concerning the impact of substance use on HCC outcomes. At the individual level, these included coping and satisfying basic needs and could influence all HCC steps (i.e., testing, treatment linkage, adherence, and retention, and viral load suppression). The interpersonal level themes included stigma issues and providers' cultural competence and treatment attitudes and primarily influenced treatment linkage, retention, and viral load suppression. These same HCC steps were influenced at the health care systems level by organizations' physical environment and resources as well as intra-/inter-agency communication. Testing and retention were the most likely steps to affect at the policy/society level, and the themes included opposition within an organization or community, and activities with unintended consequences. CONCLUSIONS The most substantial HCC challenges for PLWH with substance use problems included linking and retaining in treatment those with multiple co-morbidities and meeting their basic living needs. Recommendations to improve HCC outcomes for PLWH with substance use problems include increasing easy access to effective drug and mental health treatment, expanding case management and peer navigation services, training staff about harm reduction, de-stigmatizing, and culturally competent approaches to interacting with patients, and increasing information-sharing and service coordination among service providers and the social service and criminal justice systems.

Abstract
Human Immunodeficiency Virus (HIV) is a progressive infection that targets the immune system, affecting more than 37 million people around the world. While combinatorial antiretroviral therapy (cART) has lowered mortality rates and improved quality of life in infected individuals, the prevalence of HIV associated neurocognitive disorders is increasing and HIV associated cognitive decline remains prevalent. Recent research has suggested that HIV accessory proteins may be involved in this decline, and several studies have indicated that the HIV protein transactivator of transcription (Tat) can disrupt normal neuronal and glial function. Specifically, data indicate that Tat may directly impact dopaminergic neurotransmission, by modulating the function of the dopamine transporter and specifically damaging dopamine-rich regions of the CNS. HIV infection of the CNS has long been associated with dopaminergic dysfunction, but the mechanisms remain undefined. The specific effect(s) of Tat on dopaminergic neurotransmission may be, at least partially, a mechanism by which HIV infection directly or indirectly induces dopaminergic dysfunction. Therefore, precisely defining the specific effects of Tat on the dopaminergic system will help to elucidate the mechanisms by which HIV infection of the CNS induces neuropsychiatric, neurocognitive and neurological disorders that involve dopaminergic neurotransmission. Further, this will provide a discussion of the experiments needed to further these investigations, and may help to identify or develop new therapeutic approaches for the prevention or treatment of these disorders in HIV-infected individuals.

Abstract
Background Interventions are needed to improve viral suppression rates among persons with HIV
and substance use. A 3-arm randomized multi-site study (Metsch et al. in JAMA 316:156–70, 2016) was conducted to evaluate the effect on HIV outcomes of usual care referral to HIV and substance use services (N = 253) versus patient navigation delivered alone (PN: N = 266) or together with contingency management (PN + CM; N = 271) that provided financial incentives targeting potential behavioral mediators of viral load suppression. Aims This secondary analysis evaluates the effects of financial incentives on attendance at PN sessions and the relationship between session attendance and viral load suppression at end of the intervention. Methods Frequency of sessions attended was analyzed over time and by distribution of individual session attendance frequency (PN vs PN + CM). Percent virally suppressed (≤200 copies/mL) at 6 months was compared for low, medium and high rate attenders. In PN + CM a total of $220 could be earned for attendance at 11 PN sessions over the 6-month intervention with payments ranging from $10 to $30 under an escalating schedule. Results The majority (74%) of PN-only participants attended 6 or more sessions but only 28% attended 10 or more and 16% attended all eleven sessions. In contrast, 90% of PN + CM attended 6 or more visits, 69% attended 10 or more and 57% attended all eleven sessions (attendance distribution χ2[11] = 105.81; p < .0001). Overall (PN and PN + CM participants combined) percent with viral load suppression at 6-months was 15, 38 and 54% among those who attended 0–5, 6–9 and 10–11 visits, respectively (χ2(2) = 39.07, p < .001). Conclusion In this secondary post hoc analysis, contact with patient navigators was increased by attendance incentives. Higher rates of attendance at patient navigation sessions was associated with viral suppression at the 6-month follow-up assessment. Study results support use of attendance incentives to improve rates of contact between service providers and patients, particularly patients who are difficult to engage in care.

Abstract
HIV is common among individuals with substance use disorders, but relatively few studies have examined the impact of HIV status on response to substance abuse treatment. This secondary analysis compared patients seeking treatment for cocaine use with and without HIV in terms of substance use treatment outcomes. Primary treatment outcomes included treatment retention, longest duration of abstinence, and percent of negative samples; both substance use outcomes reflect abstinence from cocaine, alcohol and opioids concurrently. Participants (N=432) were enrolled in randomized clinical trials comparing contingency management (CM) to standard care, and 32 (7%) reported being positive for HIV. Overall, CM improved both treatment retention (average of 8.2weeks compared to 6.0weeks in the standard care condition) and longest duration of abstinence (average of 5.8weeks compared to 2.8weeks in the standard care condition). HIV status was not associated with treatment outcomes as a main effect, nor did it have an interaction effect with treatment condition. These results suggest a benefit of CM in substance abuse treatment irrespective of HIV status.

Abstract
Transgender women living with HIV experience high rates of substance use, violence, and post-traumatic stress disorder (PTSD). Seeking Safety is a manualized, present-focused, cognitive-behavioral therapy program designed to address co-occurring substance use and PTSD. Seeking Safety has evidence of efficacy in a variety of populations but had not been evaluated specifically with people living with HIV or transgender women. We pilot-tested a 12-session Seeking Safety program with a group of transgender women living with HIV who reported substance use and a history of violence. Seven transgender women living with HIV were recruited from two HIV primary care clinics in San Francisco and completed pre- and post-intervention assessments. Participants attended an average of 8 of the 12 sessions. Mean scores for all three outcome measures improved: PTSD symptom scores declined 17.5%, alcoholism screening scores declined 23.9%, and drug abuse screening scores declined 68.8%, on average. Despite the small sample, this pilot study showed Seeking Safety to be a promising intervention among transgender women living with HIV. The findings are encouraging and justify larger studies of Seeking Safety among transgender women and other people living with HIV who experience high rates of substance use and PTSD.

Impact of illicit opioid use on T cell subsets among HIV-infected adults. PLoS One 2017; 12:e0176617. [PMID: 28472064 PMCID: PMC5417591 DOI: 10.1371/journal.pone.0176617] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2016] [Accepted: 04/13/2017] [Indexed: 12/18/2022] Open
Abstract
Objectives Opioids have immunosuppressive properties, yet opioid effects on T cell abnormalities consistent with the immune risk phenotype among HIV-infected individuals are understudied. Methods To assess associations between illicit opioid use and T cell characteristics (CD4/CD8 ratio, memory profiles based on CD45RO and CD28 expression, and senescence based on CD57 expression), we conducted an exploratory cross-sectional analysis of Russia ARCH, a cohort of antiretroviral therapy (ART)-naïve HIV-infected individuals recruited 11/2012 to 10/2014 in St. Petersburg, Russia. The main independent variable was past 30 day illicit opioid use (yes vs. no). Secondary analyses evaluated none (0 days), intermittent (1 to 7 days), and persistent (8 to 30 days) opioid use. Outcomes were determined with flow cytometry. Analyses were conducted using linear regression models. Results Among 186 participants, 38% reported any illicit opioid use (18% intermittent and 20% persistent). Any illicit opioid use was not significantly associated with T cell characteristics. Intermittent opioid use appeared to be associated with decreased memory CD8+ T cells proportion (CD45RO+CD45RA- CD8+ T cells: adjusted mean difference [AMD] [95% CI] = -6.15 [-11.50, -0.79], p = 0.02) and borderline significant increased senescent T cells (%CD57+ of total CD28-CD8+ T cells (AMD [95% CI] = 7.70 [-0.06, 15.46], p = 0.05). Conclusions Among ART-naïve HIV-infected Russians, any illicit opioid use was not significantly associated with T cell abnormalities although intermittent illicit opioid use may be associated with CD8 T cell abnormalities. Longitudinal studies are warranted to confirm these findings given increased risk of infections and comorbidities seen among HIV-infected individuals with illicit opioid use.

Abstract
Compared to HIV-infected persons who do not inject drugs (non-IDU), persons who inject drugs (PWID) experience disparities in linking to medical care, initiating antiretroviral therapy (ART) and achieving viral suppression. There has been little attention to changes in these disparities over time. We estimated the proportion of PWID and non-IDU retained in care, on ART, and virally suppressed each year from 2001-2012 in the Johns Hopkins HIV Clinical Cohort (JHHCC). We defined active clinic patients as those who had ≥1 clinical visit, CD4 cell count, or viral load between July 1 of the prior year, and June 30 of the analysis year. Within a calendar year, retention was defined as ≥2 clinical visits or HIV-related laboratory measurements >90 days; ART use was defined as ≥1 ART prescription active ≥30 days; and viral suppression was defined as ≥1 HIV viral load <400 copies/mL. While PWID were less likely to be retained in earlier years, the gaps in retention closed around 2010. After 2003-2004, PWID and non-IDU retained in care had similar probability of receiving a prescription for ART and PWID and non-IDU on ART had similar probability of viral suppression.

Reducing non-injection drug use in HIV primary care: A randomized trial of brief motivational interviewing, with and without HealthCall, a technology-based enhancement. J Subst Abuse Treat 2016; 74:71-79. [PMID: 28132704 DOI: 10.1016/j.jsat.2016.12.009] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2016] [Revised: 12/14/2016] [Accepted: 12/28/2016] [Indexed: 01/18/2023]
Abstract
AIMS In HIV-infected individuals, non-injection drug use (NIDU) compromises many health outcomes. In HIV primary care, the efficacy of brief motivational interviewing (MI) to reduce NIDU is unknown, and drug users may need greater intervention. We designed an enhancement to MI, HealthCall (HC), for daily patient self-monitoring calls to an interactive voice response (IVR) phone system, and provided participants with periodic personalized feedback. To reduce NIDU among HIV primary care patients, we compared the efficacy of MI+HealthCall to MI-only and an educational control condition. DESIGN Participants age >18 with >4days of NIDU during the prior 30days were recruited from large urban HIV primary care clinics. Of the 240 participants, 83 were randomly assigned to control, 77 to MI-only, and 80 to MI+HC. Counselors provided educational control, MI-only or MI+HC at baseline. At 30 and 60days (end-of-treatment), counselors briefly discussed drug use, moods and health behaviors, using HealthCall-generated graphs with MI+HC patients. Primary outcomes (last 30days) were number of days used primary drug (NumDU), and total quantity of primary drug used (dollar amount spent; QuantU), derived from the Time-Line Follow-Back. FINDINGS Across all groups, at end-of-treatment, frequency and quantity of NIDU decreased, with significantly greater reductions in the MI-Only group. A twelve-month post-treatment follow-up indicated sustained benefits of MI+HC and MI-only relative to control. CONCLUSIONS Brief interventions can be successfully used to reduce non-injection drug use in HIV primary care. IVR-based technology may not be sufficiently engaging to be effective. Future studies should investigate mobile technology to deliver a more engaging version of HealthCall to diverse substance abusing populations.

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.

Assessing Problematic Substance Use in HIV Care: Which Questions Elicit Accurate Patient Disclosures? J Gen Intern Med 2016; 31:1141-7.

Abstract
BACKGROUND Substance use is associated with higher rates of antiretroviral non-adherence and poor HIV outcomes. This study examined how HIV care providers assess substance use, and which questions elicit accurate patient disclosures. METHODS We conducted a conversation analysis of audio-recorded encounters between 56 providers and 162 patients living with HIV (PLWH) reporting active substance use in post-encounter interviews (cocaine or heroin use in the past 30 days, > 4 days intoxicated in past 30 days, or AUDIT score ≥ 8). We assessed the frequency of substance use discussion, characterized the types of questions used by providers, and determined the frequency of accurate patient disclosure by question type. RESULTS In 55 reports of active substance use, providers already knew about the use (n = 16) or patients disclosed unpromptednn = 39). Among the remaining 155 instances of substance use in which providers had the opportunity to elicit disclosure, 78 reports (50 %) of substance use were not discussed. Of the remaining 77 reports in which the provider asked about substance use, 55 (71 %) patients disclosed and 22 (29 %) did not disclose. Questions were classified as: open-ended (n = 18, "How's the drinking going?"); normalizing (n = 14, "When was the last time you used?"); closed-ended (n = 36, "Have you used any cocaine?"); leading towards non-use (n = 9, "Have you been clean?"). Accurate disclosure followed 100 % of open-ended and normalizing questions, 58 % of closed-ended questions, and 22 % of leading questions. After adjusting for drug type, closed-ended questions were 41 % less likely (p < 0.001), and 'leading' questions 78 % less likely (p = 0.016) than broad and normalizing questions to elicit disclosures. CONCLUSION Providers in this sample missed almost half of the opportunities to identify and discuss substance use with PLWH. Providers can increase the probability of patient disclosure by using open-ended or normalizing questions that ask about the "last time" that the patient used drugs or alcohol.

Abstract
OBJECTIVES We present a novel, patient-centric, longitudinal summary of patient progress through the HIV care continuum. Using this new approach, we compare person-time spent alive, in care, on antiretroviral therapy (ART), and virally suppressed among people who inject drugs (PWID) and those who do not (non-IDU). DESIGN Prospective clinical observational cohort study. METHODS We followed ART-naive patients with detectable HIV viral loads who enrolled in the Johns Hopkins HIV Clinical Cohort from enrollment until the occurrence of several care continuum-related milestones, including ART initiation and viral suppression, and until several care continuum-related failures, including loss to clinic and death. We added and subtracted cumulative incidence curves to estimate the proportion of the cohort in each of seven continuum stages across the 10 years following enrollment in clinical care. RESULTS PWID composed 32% of the study sample (n = 1443). Over 10 years following enrollment in care, PWID and non-IDU spent only 23 and 37%, respectively, of person-time in care, on ART, and virally suppressed. PWID lost 8.9 more months of life compared with non-IDU and spent an additional 5.0 months on ART but not virally suppressed, and an additional 5.5 months in care but not on ART. There were not meaningful improvements in the 5-year restricted mean person-time differences comparing PWID to non-IDU across enrollment cohorts (2000-2003, 2004-2007, 2008-2014). CONCLUSION Efforts to increase viral suppression among PWID should focus on increasing ART initiation and improving adherence to therapy.

Abstract
Tobacco smoking is associated with adverse health effects among people living with HIV (PLWH), including a higher risk of cancer and cardiovascular problems. Further, there is evidence that PLWH are two to three times more likely to smoke than the general population. The aim of this study was to examine the association between tobacco smoking and biomarkers of HIV disease progression, including unsuppressed viral load (viral load >200 copies/mL) and low CD4 cell count (<200 cells/mm(3)). Recent tobacco smoking was reported by 40 % (n = 5942) of 14,713 PLWH enrolled in Ryan White Part A programs in the New York City metropolitan area. In multivariate analyses controlling for sociodemographic and clinical characteristics, recent tobacco smoking was independently associated with unsuppressed viral load (AOR = 1.38, CI 1.26-1.50) and low CD4 cell count (AOR = 1.12, CI 1.01-1.24). Findings suggest the importance of routine assessments of tobacco use in clinical care settings for PLWH.

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
OBJECTIVE Incidence of HIV-associated non-AIDS (HANA) related comorbidities is increasing in HIV-infected individuals. Our objective was to estimate the risk of HANA comorbidity associated with history of injection drug use (IDU) correctly accounting for higher death rates among people who inject drugs (PWID). DESIGN We followed HIV-infected persons aged 25-59 years who enrolled in the Johns Hopkins HIV Clinical Cohort between 1995 and May 2014, from enrollment until HANA comorbidity diagnosis, death, age 60, or administrative censoring. METHODS We compared cumulative incidence ('risk'), by age, of validated diagnoses of HANA comorbidities among HIV-infected PWID and non-IDU; specifically, we considered end-stage renal disease (ESRD), end-stage liver disease (ESLD), myocardial infarction, stroke, and non-AIDS-defining cancer. We used competing risk methods appropriate to account for death, standardized to the marginal distribution of baseline covariates, and adjusted for potential differential loss-to-clinic. RESULTS Of 5490 patients included in this analysis, 37% reported IDU as an HIV transmission risk. By age 55 years, PWID had higher risk of ESLD [risk difference = 6.8, 95% confidence interval (CI): -1.9, 15.5] and ESRD (risk difference = 11.1, 95% CI: 1.2, 21.0) than did non-IDU. Risk of myocardial infarction and stroke were similar among PWID and non-IDU. Risk of non-AIDS-defining cancer was lower among PWID than among non-IDU (risk difference at 55 years: -4.9, 95% CI: -11.2, 1.3). CONCLUSION Not all HANA comorbidities occur with higher incidence in PWID compared with non-IDU. However, higher incidence of ESRD and ESLD among PWIDs highlights the importance of recognition and management of markers of these comorbidities in early stages among PWID.

Abstract
Understanding the nexus of aging, HIV, and substance use is key to providing appropriate services and support for their aging, HIV seropositive patients. The proportion of PLWHA aged 50 and older is growing due to a variety of factors like decreases in mortality due to highly active retroviral therapy and non-negligible HIV incidence. We describe prevalence of alcohol, tobacco, and other drug use and participation in substance use treatment and 12-step programs among 95 HIV-positive patients aged 50 and older engaged in care. Most (73.7%) smoked cigarettes in their lifetime and 46.3% were current smokers. Most were at medium (81.1%) or high risk (13.7%) for an alcohol use disorder. With respect to illicit drug use, 48.4% had used marijuana, cocaine, crack, methamphetamines, heroin, and/or prescription opiates without a prescription in the last 12 months; 23.2% met criteria for drug dependence. Marijuana was the most commonly reported illicit drug (32.6%) followed by cocaine and crack (10.5% each), heroin and prescription opiates (7.4% each), and methamphetamines (6.3%). Among those who had not used drugs in the past 12 months, 36.7% had been in a substance use treatment program and 26.5% had participated in a 12-step program in their lifetime; 8.2% were currently in treatment and 16.3% were currently participating in a 12-step program. Among those who had used an illicit drug in the past 12 months, 37.0% had never been in treatment, 34.8% had been in treatment in their lifetime, and 28.3% were currently in treatment. With respect to 12-step programs, 27.3% of those meeting dependence criteria had never participated, 45.5% had participated in their lifetimes, and 27.3% were currently participating. Our findings suggest that older adults in HIV care settings could benefit from Screening, Brief Intervention, and Referral to Treatment interventions and/or integrated services for substance abuse and medical treatment.

Abstract
BACKGROUND Persons living with HIV (PLWH) and substance use/misuse experience significant barriers to engagement in HIV care at every step of the HIV care continuum including: (1) HIV testing and diagnosis (2) linkage to clinical care (3) retention in care pre-antiretroviral therapy (ART) (4) ART initiation and adherence (5) viral suppression. We qualitatively explored the facilitators of and barriers to participation in the HIV care continuum among PLWH with substance use/misuse. METHODS We performed semi-structured in-depth interviews with 34 PLWH in care with recent substance use. The transcripts were analyzed in an iterative process using an editing style analysis. Interviews were conducted until thematic saturation was achieved. RESULTS Participants attributed an escalation in drug use at the time of diagnosis to denial of their disease and the belief that their death was inevitable and cited this as a barrier to treatment entry. In contrast, participants reported that experiencing adverse physical effects of uncontrolled HIV infection motivated them to enroll in care. Reported barriers to retention and adherence to care included forgetting medications and appointments because of drug use, prioritizing drug use over HIV treatment and side effects associated with medications. Participants described that progression of illness, development of a medication taking ritual and a positive provider-patient relationship all facilitated engagement and reengagement in care. CONCLUSIONS PLWH with substance use engaged in care describe barriers to and facilitators of optimal engagement related to and distinct from substance use. Greater understanding of the biologic, psychological and social factors that promote and impair engagement in care can inform interventions and reduce the increased morbidity and mortality experienced by PLWH with substance use.
