Abstract
Among people living with HIV (PLWH), heavy alcohol use is associated with many negative health consequences. However, the impacts of heavy alcohol use are not well described for PLWH who use drugs. Thus, we investigated the prevalence and correlates of heavy alcohol use among a cohort of people who use drugs (PWUD) living with HIV in Vancouver, Canada. We accessed data from an ongoing community-recruited prospective cohort of PLWH who use drugs with linked comprehensive HIV clinical monitoring data. We used generalized linear mixed-effects modeling to identify factors longitudinally associated with periods of heavy alcohol use between December 2005 and December 2019. Of the 896 participants included, 291 (32.5%) reported at least one period with heavy alcohol use. Periods of recent incarceration (Adjusted Odds Ratio [AOR] = 1.48, 95% Confidence Interval [CI]: 1.01-2.17), encounters with police (AOR = 1.87, 95% CI: 1.37-2.56), and older age (AOR = 1.05, 95% CI: 1.02-1.07) were positively associated with heavy alcohol use. Engagement in drug or alcohol treatment (AOR = 0.54, 95% CI: 0.42-0.70) and male gender (AOR = 0.46; 95% CI: 0.27-0.78) were negatively associated with heavy alcohol use. We observed that heavy alcohol use was clearly linked to involvement with the criminal justice system. These findings, together with the protective effects of substance use treatment, suggest the need to expand access for drug and alcohol treatment programs overall, and in particular through the criminal justice system to reduce alcohol-related harms among PLWH who use drugs.

Addict Behav Rep 2023; 17:100486. [PMID: 36950716 PMCID: PMC10025983 DOI: 10.1016/j.abrep.2023.100486] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Revised: 02/27/2023] [Accepted: 03/07/2023] [Indexed: 03/14/2023] Open
Abstract
Objectives People living with HIV (PWH) with substance or alcohol use often have unsuppressed plasma HIV viral loads (pVL). The degree to which substance and alcohol use effects on HIV viral suppression are mediated through medication nonadherence is incompletely understood. Methods We included PWH prescribed antiretroviral therapy and receiving care at an academic HIV clinic between 2014 and 2018 who completed both patient-reported outcomes (PRO) questionnaires and had subsequent pVL measurements. Measures included assessments of alcohol use (AUDIT-C), drug use (NIDA-ASSIST), and self-reported adherence measured using four different methods. Substances found in bivariate analysis to predict detectable pVL were modeled separately for mediation effects through adherence. We report natural direct (NDE) and indirect effect (NIE), marginal total effect (MTE), and percentage mediated. Results Among 3125 PWH who met eligibility criteria, 25.8% reported hazardous alcohol use, 27.1% cannabis, 13.1% amphetamines, 1.9% inhalants, 5.3% cocaine, 4.5% sedative-hypnotics, 2.9% opioids, and 2.3% hallucinogens. Excellent adherence was reported by 58% of PWH, and 10% had detectable pVL. Except for sedatives, using other substances was significantly associated with worse adherence. Bivariate predictors of detectable pVL were [OR (95% CI)]: amphetamine use 2.4 (1.8-3.2) and opioid use 2.3 (1.3-4.0). The percent of marginal total effect mediated by nonadherence varied by substance: 36% for amphetamine use, 27% for opioid use, and 39% for polysubstance use. Conclusion Use of amphetamines, opioids, and multiple substances predicted detectable pVL. Up to 40% of their effects were mediated by self-reported nonadherence. Confirmation using longitudinal measurement models will strengthen causal inference from this cross-sectional analysis.

Diagnosis, Treatment, and Prevention of HIV Infection among Detainees: A Review of the Literature. Healthcare (Basel) 2022; 10:healthcare10122380. [PMID: 36553904 PMCID: PMC9777892 DOI: 10.3390/healthcare10122380] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 11/23/2022] [Accepted: 11/24/2022] [Indexed: 11/29/2022] Open
Abstract
Detainees are one of the most vulnerable populations to human immunodeficiency virus (HIV). This is mostly caused by the lack of knowledge on the topic among the inmates; the lack of prophylaxis; the high percentage of risky behaviors in jail, such as sexual abuse, unprotected sexual intercourses, and injective drug use; and the generally low perception of the risk of transmission. It has also been observed that the problem does not cease to exist at the moment of release, but it also may be aggravated by the weak support system or the total absence of programs for people living with HIV/AIDS (PLWHA) to avoid discontinuation of antiretroviral drugs. Difficulty in providing housing and jobs and, therefore, a form of stability for ex-detainees, also contributes to none adherence to antiretroviral therapy. Among the detainees, there are also categories of people more susceptible to discrimination and violence and, therefore, to risky behaviors, such as black people, Hispanics, transgender people, and men who have sex with men (MSM). We reviewed the literature in order to provide a more complete picture on the situation of PLWHA in jail and to also analyze the difficulties of ex-detainees in adhering to HIV therapy.

Abstract
The intestinal microbiome is an essential so-called human "organ", vital for the induction of innate immunity, for metabolizing nutrients, and for maintenance of the structural integrity of the intestinal barrier. HIV infection adversely influences the richness and diversity of the intestinal microbiome, resulting in structural and functional impairment of the intestinal barrier and an increased intestinal permeability. Pathogens and metabolites may thus cross the "leaky" intestinal barrier and enter the systemic circulation, which is a significant factor accounting for the persistent underlying chronic inflammatory state present in people living with HIV (PLWH). Additionally, alcohol use and abuse has been found to be prevalent in PLWH and has been strongly associated with the incidence and progression of HIV/AIDS. Recently, converging evidence has indicated that the mechanism underlying this phenomenon is related to intestinal microbiome and barrier function through numerous pathways. Alcohol acts as a "partner" with HIV in disrupting microbiome ecology, and thus impairing of the intestinal barrier. Optimizing the microbiome and restoring the integrity of the intestinal barrier is likely to be an effective adjunctive therapeutic strategy for PLWH. We herein critically review the interplay among HIV, alcohol, and the gut barrier, thus setting the scene with regards to development of effective strategies to counteract the dysregulated gut microbiome and the reduction of microbial translocation and inflammation in PLWH.

Abstract
The HIV treatment cascade is an effective tool to track progress and gaps in the HIV response among key populations. People who inject drugs (PWID) remain the most affected key population in Ukraine with HIV prevalence of 22% in 2015. We performed secondary analysis of the 2017 Integrated Bio-Behavioral Surveillance (IBBS) survey data to construct the HIV treatment cascade for PWID and identify correlates of each indicator achievement. The biggest gap in the cascade was found in the first "90", HIV status awareness: only 58% [95% CI: 56%-61%] of HIV-positive PWID reported being aware of their HIV-positive status. Almost 70% [67%-72%] of all HIV-infected PWID who were aware of their status reported that they currently received antiretroviral therapy (ART). Almost three quarters (74% [71%-77%]) of all HIV-infected PWID on ART were virally suppressed. Access to harm reduction services in the past 12 months and lifetime receipt of opioid agonist treatment (OAT) had the strongest association with HIV status awareness. Additionally, OAT patients who were aware of HIV-positive status had 1.7 [1.2-2.3] times the odds of receiving ART. Being on ART for the last 6 months or longer increased odds to be virally suppressed; in contrast, missed recent doses of ART significantly decreased the odds of suppression. The HIV treatment cascade analysis for PWID in Ukraine revealed substantial gaps at each step and identified factors contributing to achievement of the outcomes. More intensive harm reduction outreach along with targeted case finding could help to fill the HIV awareness gap among PWID in Ukraine. Scale up of OAT and community-level linkage to care and ART adherence interventions are viable strategies to improve ART coverage and viral suppression among PWID.

Abstract
INTRODUCTION While considerable progress has been made in the fight against HIV/AIDS, to date there has not been a cure, and millions of people around the world are currently living with HIV/AIDS. People living with HIV/AIDS have substance abuse disorders at higher rates than non-infected individuals, which puts them at an increased risk of drug-drug interactions. AREAS COVERED Potential drug-drug interactions are reviewed for a variety of potential drugs of abuse, both licit and illicit. These drugs include alcohol, cigarettes or other nicotine delivery systems, methamphetamine, cocaine, opioids, and marijuana. Potential interactions include decreased adherence, modulation of drug transporters, or modulation of metabolic enzymes. We also review the relative incidence of the use of these drugs of abuse in People living with HIV/AIDS. EXPERT OPINION Despite considerable improvements in outcomes, disparities in outcomes between PLWHA who use drugs of abuse, vs those who do not still exist. It is of critical necessity to improve outcomes in these patients and to work with them to stop abusing drugs of abuse.

Abstract
BACKGROUND Incarcerated people are at increased risk of human immunodeficiency virus (HIV) infection relative to the general population. Despite a high burden of infection, HIV care use among prison populations is often suboptimal and varies among settings, and little evidence exists explaining the discrepancy. Therefore, this review assessed barriers to optimal use of HIV care cascade in incarcerated people. METHODS Quantitative and qualitative studies investigating factors affecting linkage to care, ART (antiretroviral therapy) initiation, adherence and/or outcomes among inmates were systematically searched across seven databases. Studies published in English language and indexed up to 26 October 2018 were reviewed. We performed a narrative review for both quantitative and qualitative studies, and meta-analyses on selected quantitative studies. All retrieved quantitative studies were assessed for risk of bias. Meta-analyses were conducted using RevMan-5 software and pooled odds ratios were calculated using Mantel-Haenszel statistics with 95% confidence interval at a p<0.05. The review protocol has been published at the International Prospective Register of Systematic Reviews (PROSPERO; Number: CRD42019135502). RESULTS Of forty-two studies included in the narrative review, eight were qualitative studies. Sixteen of the quantitative studies were eligible for meta-analyses. The narrative synthesis revealed structural factors such as: a lack of access to community standard of HIV care, particularly in resource limited countries; loss of privacy; and history of incarceration and re-incarceration as risk factors for poor HIV care use in prison populations. Among social and personal characteristics, lack of social support, stigma, discrimination, substance use, having limited knowledge about, and negative perception towards ART were the main determinants of suboptimal use of care in incarcerated people. In the meta-analyses, lower odds of ART initiation was noticed among inmates with higher baseline CD4 count (CD4 ≥500celss/mm3) (OR = 0.37, 95%CI: 0.14-0.97, I2 = 43%), new HIV diagnosis (OR = 0.07, 95%CI: 0.05-0.10, I2 = 68%), and in those who lacked belief in ART safety (OR = 0.32, 95%CI: 0.18-0.56, I2 = 0%) and efficacy (OR = 0.31, 95%CI: 0.17-0.57, I2 = 0%). Non-adherence was high among inmates who lacked social support (OR = 3.36, 95%CI: 2.03-5.56, I2 = 35%), had low self-efficiency score (OR = 2.50, 95%CI: 1.64,-3.80, I2 = 22%) and those with depressive symptoms (OR = 2.02, 95%CI: 1.34-3.02, I2 = 0%). Lower odds of viral suppression was associated with history of incarceration (OR = 0.40, 95%CI: 0.35-0.46, I2 = 0%), re-incarceration (OR = 0.09, 95%CI: 0.06-0.13, I2 = 64%) and male gender (OR = 0.55, 95%CI: 0.42-0.72, I2 = 0%). Higher odds of CD4 count <200cells/mm3 (OR = 2.01, 95%CI: 1.62, 2.50, I2 = 44%) and lower odds of viral suppression (OR = 0.20, 95%CI: 0.17-0.22, I2 = 0%) were observed during prison entry compared to those noticed during release. CONCLUSION Given the high HIV risk in prison populations and rapid movements of these people between prison and community, correctional facilities have the potential to substantially contribute to the use of HIV treatment as a prevention strategy. Thus, there is an urgent need for reviewing context specific interventions and ensuring standard of HIV care in prisons, particularly in resource limited countries.

Abstract
Among HIV-positive people who use illicit drugs (PWUD) in our setting, repeated periods of incarceration adversely affect ART adherence in a dose-dependent manner. However, the impact of non-custodial criminal justice involvement on HIV-related outcomes has not been previously investigated. Data were obtained from a longitudinal cohort of HIV-positive PWUD in a setting of universal no-cost ART and complete dispensation records. Multivariate generalized estimating equations were used to calculate the longitudinal odds of having a detectable HIV VL (VL) associated with custodial and non-custodial CJS exposure. Between 2005 and 2014, 716 HIV-positive ART-exposed PWUD were recruited. In multivariate analysis, both custodial [Adjusted odds ratio (AOR) 0.61, 95% CI 0.45-0.82] and noncustodial (AOR 0.78, 95% CI 0.62-0.99) involvement in the criminal justice system was associated with detectable HIV VL. Among HIV-positive PWUD, both custodial and non-custodial criminal justice involvement is associated with worse HIV treatment outcomes. Our findings highlight the need for increased ART adherence support across the full spectrum of the criminal justice system.

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.

Abstract
BACKGROUND Low levels of medical care engagement have been noted for HIV-positive people leaving systems of incarceration in the United States. Substance misuse frequently co-occurs with criminal justice involvement in individuals who are living with HIV. METHODS We analyzed data from in-depth interviews with 19 HIV-positive individuals who were currently or formerly incarcerated in order to elucidate challenges faced in accessing care and maintaining HIV treatment regimens when cycling out of (and often back into) custody. Our thematic analysis used an ecosocial framework to describe participants' shifts between substance use treatment, medical care, and criminal justice systems. RESULTS Dominant themes included the dramatic increase in HIV-treatment-related autonomy required following release from jail because of differences in care delivery between custody-based and community-based care systems; the important, but temporary stabilization provided by residential substance use treatment programmes; and the inconsistency of substance use treatment approaches with chronic care models of disease management. CONCLUSION Enhanced integration of criminal justice, medical care, and substance use treatment institutions in planning for reentry of HIV populations may ease the impact of the dramatic shifts in context that often dissuade linkage and retention. This integration should include coordination with custody release processes, periodic assessments for active substance misuse in HIV treatment settings, support for (re)establishing health-promoting social networks, and options for long-term, residential substance use treatment programmes.

Abstract
The HIV epidemic in Estonia affects the population of people who inject drugs (PWID) the most, but factors associated with adherence to antiretroviral therapy (ART) among PWID have not been thoroughly examined in Estonia, with particularly limited data regarding beliefs and attitudes of PWID. The objective of this study was to explore the association between ART adherence and individual beliefs, perceived effectiveness of ART, and self-rated health in particular, in this specific population. The study used baseline survey data from a longitudinal intervention study of HIV prevention among PWID in Estonia, in which 107 HIV-infected participants reported current use of ART. Current adherence was measured through the use of a visual analog scale. Approximately half (49%) of the participants reported optimal (≥95%) adherence. The vast majority (81%) believed in the effectiveness of ART. Less than a quarter of the participants (22%) rated their health as good or very good, and a half (52%) reported average health. Individual beliefs and self-reported health were not associated with ART adherence in both bivariate and multivariable analyses. Participants with problem drinking reported significant suboptimal adherence to ART (adjusted odds ratio [AOR] 0.42, 95% CI 0.19-0.97). Daily injection drug use was also associated with suboptimal adherence (AOR 0.34, 95% CI 0.13-0.91). Problem drinking has not been commonly reported as a factor of suboptimal ART adherence among PWID; further research would be useful to identify the pathways that might be involved.

Abstract
BACKGROUND Despite the fact that prisoners are exposed to different health problems, prison health problems are often overlooked by researchers and no previous study has investigated nutritional problems of prisoners in Ethiopia. METHODS Cross-sectional data were collected from 809 prisoners from nine major prison setups in the Tigray region of Ethiopia. A proportional stratified sampling technique was used to select the total number of participants needed from each prison site. The outcome of this study was underweight defined as body mass index (BMI) of less than 18.5 kg/m2. Multivariable binary logistic regression was performed to identify determinants of underweight at a p-value of less than 0.05. RESULTS The prevalence of underweight was 25.2% (95% CI; 22.3%- 28.3%). Khat Chewing (OR = 2.08; 95% CI = 1.17, 3.70) and longer duration of incarceration (OR = 1.07; 95% CI = 1.01, 1.14) were associated with a significantly increased risk of underweight. Additionally, previous incarceration (OR = 1.54; 95% CI = 0.99, 2.42) was a relevant determinant of underweight with a borderline significance. In contrast, family support (OR = 0.61; 95% CI = 0.43, 0.85) and farmer occupation (OR = 0.59; 95% CI = 0.36, 0.98) compared to those who were unemployed were important protective determinants significantly associated with lower risk of underweight. CONCLUSION In summary, the burden of underweight was higher among prisoners in Tigray region who had respiratory tract infections. The study has enhanced our understanding of the determinants of underweight in the prison population. We strongly recommend that nutritional support, such as therapeutic feeding programs for severely or moderately underweight prisoners, and environmental health interventions of the prison setups should be urgently implemented to correct the uncovered nutritional problem and its associated factors for improving the health status of prisoners.

Abstract
BACKGROUND Alcohol use disorders (AUDs) are highly prevalent among persons living with HIV (PLH) within the criminal justice system (CJS). Extended-release naltrexone (XR-NTX) has not been previously evaluated among CJS-involved PLH with AUDs. METHODS A randomized, double-blind, placebo-controlled trial was conducted among 100 HIV+ prisoners with AUDs. Participants were randomized 2:1 to receive 6 monthly injections of XR-NTX or placebo starting one week prior to release. Using multiple imputation strategies for data missing completely at random, data were analyzed for the 6-month post-incarceration period. Main outcomes included: time to first heavy drinking day; number of standardized drinks/drinking day; percent of heavy drinking days; pre- to post-incarceration change in average drinks/day; total number of drinking days; and a composite alcohol improvement score comprised of all 5 parameters. RESULTS There was no statistically significant difference overall between treatment arms for time-to-heavy-drinking day. However, participants aged 20-29 years who received XR-NTX had a longer time to first heavy drinking day compared to the placebo group (24.1 vs. 9.5days; p<0.001). There were no statistically significant differences between groups for other individual drinking outcomes. A sub-analysis, however, found participants who received ≥4 XR-NTX were more likely (p<0.005) to have improved composite alcohol scores than the placebo group. Post-hoc power analysis revealed that despite the study being powered for HIV outcomes, sufficient power (0.94) was available to distinguish the observed differences. CONCLUSIONS Among CJS-involved PLH with AUDs transitioning to the community, XR-NTX lengthens the time to heavy drinking day for younger persons; reduces alcohol consumption when using a composite alcohol consumption score; and is not associated with any serious adverse events.

Abstract
BACKGROUND Alcohol abuse is an important public health problem, frequently unrecognized among people living with HIV/AIDS (PLWHA), and requires investigation and intervention. It is usually associated with lower adherence to highly active antiretroviral therapy (HAART). It can also produce adverse clinical outcomes, such as changes in certain HIV markers, particularly CD4 cell counts and HIV viral loads (VLs). Thus, this study aimed to evaluate the prevalence of alcohol abuse among PLWHA, its associated risk factors and effects on CD4 cell counts and HIV VLs in southern Brazil. METHODS Between December 2012 and July 2013, 343 patients were interviewed at a reference hospital in southern Brazil. The instrument used was the Alcohol Use Disorder Identification Test (AUDIT), and a cutoff of eight points or more was applied. Socioeconomic, demographic, clinical and laboratory data were also collected. The statistical analysis included a Poisson regression to evaluate the factors associated with alcohol use disorder, and a linear regression was performed to assess the relationship between AUDIT scores and CD4 cell counts and HIV VLs. RESULTS Alcohol abuse was present in 28.6% of the respondents, and possible dependence was present in 5%. The risk factors identified included being male, mixed or black skin color, low education and the use of intravenous or inhaled drugs. A higher AUDIT score was associated with a lower CD4 cell count but was not associated with higher HIV VL values. CONCLUSIONS Our results show the importance of screening for alcohol abuse in this group. The prevalence of alcohol abuse was high, and it was associated with socioeconomic factors and the use of illicit drugs. Moreover, AUDIT score negatively affected CD4 cell counts as well.

Abstract
BACKGROUND Alcohol is associated with a multitude of severe health consequences. While risk behaviors related to illicit drug use are commonly studied among people who inject drugs (PWID), the role of alcohol use has received substantially less attention in this population. We explored whether drug and sexual risk behaviors as well as experiences of violence were associated with hazardous alcohol use in a cohort of PWID. METHODS Analyses were conducted using observational data from a prospective cohort of community-recruited HIV-negative PWID in Vancouver, Canada. We used the U.S. National Institute on Alcohol Abuse and Alcoholism definition of hazardous alcohol use (i.e., >14 drinks/wk or >4 drinks on 1 occasion for men, and >7 drinks/wk or >3 drinks on 1 occasion for women). We used multivariable generalized estimating equations (GEE) to identify the factors associated with hazardous alcohol use. RESULTS Between 2006 and 2012, 1,114 HIV-negative individuals were recruited, and 186 (16.7%) reported hazardous alcohol use in the previous 6 months at baseline. In multivariable GEE analyses, having multiple sex partners (adjusted odds ratio [AOR] = 1.25), history of sexually transmitted infection (AOR = 1.50), experiencing violence (AOR = 1.36), and incarceration (AOR = 1.29) were each independently associated with hazardous alcohol use. Caucasian ethnicity (AOR = 0.56), ≥ daily heroin injection (AOR = 0.81), and engagement in addiction treatment (AOR = 0.84) were negatively associated with hazardous alcohol use (all p < 0.05). CONCLUSIONS A considerable proportion of PWID reported hazardous alcohol use, which was independently associated with reporting sexual, but not drug-related, HIV risk behaviors and experiencing recent violence. Findings suggest a need to integrate regular screening and evidence-based alcohol interventions into treatment efforts for PWID.

Abstract
Highly active antiretroviral therapy (HAART) has resulted in major reductions in HIV-related morbidity and mortality. However, long-term use of HAART is challenging, and substantial numbers of patients discontinue their medications prematurely. The purpose of this analysis is to describe HAART adherence rates among a large urban cohort and examine factors associated with adherence (based on refill compliance). Of the 184 eligible participants, 129 (70%) were less than 95% adherent. Variables independently associated with nonadherence included frequent heroin injection (adjusted odds ratio [AOR] = 2.6, 95% confidence interval [CI], 1.6-4.0), baseline CD4 count less than 200 cells/mm(3) (AOR = 2.5; 95% CI, 1.9-3.2), and poor treatment by health care professionals (AOR = 1.7; 95% CI, 1.2-3.0). Variables inversely associated with HAART nonadherence included attaining viral load suppression (AOR = 0.3; 95% CI, 0.2-0.5) and methadone maintenance therapy (AOR = 0.5; 95% CI, 0.4-0.9). Innovative strategies that address the social barriers facing marginalized populations are needed to support the long-term continuation of HAART.

Abstract
Alcohol use disorders (AUDs) are highly prevalent among people living with HIV/AIDS (PLWHA) and are associated with increased HIV risk behaviors, suboptimal treatment adherence, and greater risk for disease progression. We used the ADAPT-ITT strategy to adapt an evidence-based intervention (EBI), the Holistic Health Recovery Program (HHRP+), that focuses on secondary HIV prevention and antiretroviral therapy (ART) adherence and apply it to PLWHA with problematic drinking. Focus groups (FGs) were conducted with PLWHA who consume alcohol and with treatment providers at the largest HIV primary care clinic in New Orleans, LA. Overall themes that emerged from the FGs included the following: (1) negative mood states contribute to heavy alcohol consumption in PLWHA; (2) high levels of psychosocial stress, paired with few adaptive coping strategies, perpetuate the use of harmful alcohol consumption in PLWHA; (3) local cultural norms are related to the permissiveness and pervasiveness of drinking and contribute to heavy alcohol use; (4) healthcare providers unanimously stated that outpatient options for AUD intervention are scarce, (5) misperceptions about the relationships between alcohol and HIV are common; (6) PLWHA are interested in learning about alcohol's impact on ART and HIV disease progression. These data were used to design the adapted EBI.

Abstract
Lower nadir CD4 cell counts and higher HIV viral loads are associated with increased risks of adverse events in the progression of HIV disease. In cases where medical records are inaccessible or incomplete, little evidence is available regarding whether nadir CDR cell count or HIV viral load is reliably reported in any patient population. We compare survey data collected from 207 HIV-infected individuals detained in San Francisco jails to data collected from electronic medical records (EMR) kept by the jails and community health providers. The sensitivity of self-reported nadir CD4 cell count less than 200 was 82 % [95 % confidence interval (CI) 68, 88], and the sensitivity of reporting an undetectable most recent HIV viral load was 93 % (95 % CI 84, 97). This suggests that in a highly socially marginalized population, nadir CD4 cell count and most recent HIV viral load are recalled accurately when compared to EMR.

Abstract
BACKGROUND Alcohol use disorders (AUDs) are a frequent comorbidity in a large percentage of people living with HIV/AIDS (PLWHA). PLWHA with comorbid AUDs are consistently found to perform poorly at most levels of the HIV treatment cascade, resulting in a higher likelihood of virologic nonsuppression. This has been partly attributed to lower rates of persistence with and adherence to antiretroviral therapies (ART). Focus groups of in-care PLWHA identify the need to suspend ART on drinking days because of the potential for toxicity and/or lack of therapeutic effectiveness. The aim of this study was to examine whether chronic binge alcohol (CBA) consumption decreases the effectiveness of uninterrupted ART, specifically that of nucleoside reverse-transcriptase inhibitors (NRTI) tenofovir and emtricitabine in suppressing viral replication, or results in drug toxicity in simian immunodeficiency virus (SIV)-infected rhesus macaques. METHODS Daily CBA or isocaloric sucrose (SUC) administration was initiated 3 months prior to intrarectal SIVmac251 inoculation and continued throughout the study period. ART was initiated 2.5 months after SIV infection and continued through the study period. RESULTS CBA administration did not prevent or delay the ART-mediated reduction in viral load. Following ART, circulating levels of total protein and creatinine were significantly higher than baseline values in both SUC- and CBA-treated animals, but still within a normal range. No evidence of ART toxicity was observed in either CBA- or SUC-administered macaques. CONCLUSIONS These findings indicate that CBA does not attenuate effectiveness of NRTI suppression of viral load, nor does it appear to interact with NRTI to produce toxicity during the initial 2 months of treatment. We conclude that while efforts to reduce AUD in PLWHA should be a priority, counseling on the importance of adherence to ART even on drinking days should also be promoted.

Abstract
BACKGROUND AND OBJECTIVES One in seven HIV-infected individuals is incarcerated each year. We used data from the Veterans Aging Cohort Study (VACS) to explore the relationship between incarceration and HIV disease outcomes and evaluate potential mediators of this relationship. METHODS HIV disease outcomes included: low CD4 counts (<200 cells/mL), detectable viral RNA loads (>500 copies/mL), and the VACS Index score. We performed a mediation analysis among 1,591 HIV-infected patients to examine whether unhealthy alcohol use, drug use, primary care engagement, or antiretroviral adherence mediated observed associations. RESULTS Among 1,591 HIV-infected patients, 47% reported having a history of incarceration. In multivariate analyses, a history of incarceration was associated with a higher VACS Index score (β 2.47, 95% CI 0.52-4.43). Mediation analysis revealed that recent drug use attenuated the association by 22% (β 1.93, 95% CI -0.06, 3.91) while other proposed mediators did not. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE Improving access to drug treatment when incarcerated and upon release may be an important target to improving the health of HIV-infected individuals with a history of incarceration.

Abstract
HIV disease and alcohol independently influence the human immune system, so it stands to reason that, together, their influence may be additive. Here, we review the evidence that alcohol can exacerbate HIV's influence on the immune system, thereby affecting disease progression and transmission. We focus particularly on alcohol's effect on the mucosal immune system in the tissues of the gastrointestinal tract, the genital tract and the lungs, all of which play a role in transmission and progression of HIV disease.

Pain is associated with risky drinking over time among HIV-infected persons in St. Petersburg, Russia. Drug Alcohol Depend 2014; 144:87-92. [PMID: 25220898 PMCID: PMC4252482 DOI: 10.1016/j.drugalcdep.2014.08.013] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2014] [Revised: 08/17/2014] [Accepted: 08/18/2014] [Indexed: 11/23/2022]
Abstract
BACKGROUND Pain is highly prevalent among persons with HIV. Alcohol may be used to "self-medicate" pain. This study examined the association between pain and risky alcohol use over time in a cohort of HIV-infected Russian drinkers. METHODS This secondary analysis utilized longitudinal data from a randomized trial of a behavioral intervention. Subjects included HIV-infected adults who reported past 6-month risky drinking and unprotected sex and were recruited from HIV and addiction treatment sites in St. Petersburg, Russia. The main independent variable was pain that at least moderately interfered with daily living. The primary outcome was past month risky drinking amounts based on NIAAA guidelines. General estimating equations (GEE) logistic regression models were used to calculate odds ratios and 95% confidence intervals for the association between pain and risky drinking over time (i.e., baseline, 6 and 12 months), adjusting for potential confounders. RESULTS Baseline characteristics of participants (n=699) were mean age of 30 (SD ±5) years, 41% female, and 22% <9th grade education. Nearly one quarter (24%) had a CD4 cell count <200 cells/μl, and only 17% were on antiretroviral therapy. Nearly half (46%) reported at least moderate pain interference in the past month and 81% were drinking risky amounts. In adjusted longitudinal GEE models, pain was significantly associated with greater odds of reporting past month risky drinking (AOR = 1.34, 95% CI: 1.05-1.71, p value=0.02). CONCLUSIONS Among a cohort of HIV-infected Russian drinkers, pain that at least moderately interfered with daily living was associated with higher odds of reporting risky drinking amounts over time.

Abstract
As international guidelines increase access to antiretroviral therapy (ART) globally, ART adherence becomes increasingly important to achieve HIV treatment as prevention (TasP) goals. In the concentrated HIV epidemic among men who have sex with men (MSM) and transgendered women (TGW) in Lima, Peru, the independent correlates of ART nonadherence were examined to inform treatment intervention priorities. Cross sectional survey of HIV-infected MSM and TGW who are engaged in clinical care in Lima, Peru. From June to August 2012, 302 HIV-infected Peruvian MSM/TGW from three clinical care sites were recruited using convenience sampling to participate in a cross-sectional computer-assisted adherence survey. Several standardized screening measures associated with ART nonadherence were examined in order to determine the independent correlates of optimal (≥90%) and perfect (100%) adherence, which were assessed using logistic regression. Of the 302 participants recruited, 263 (87.1%) were prescribed ART. Among those prescribed ART, 229 (87.1%) reported optimal and 146 (55.5%) reported perfect adherence. The prevalence of alcohol use disorders (AUD; 43.2%), alcohol dependence (5.3%), recent drug use (6.0%), and depression (44.5%) was high, and most participants had some evidence of neurocognitive impairment. Meeting criteria for having an AUD and depression were collinear (p < 0.001). On multivariate analysis, having an AUD was inversely related and the only independent correlate of optimal (AOR = 0.427; 95% CI = 0.187-0.976) and perfect (AOR = 0.552; 95% CI = 0.327-0.930) ART adherence. AUDs are highly prevalent among Peruvian HIV-infected MSM and contribute significantly to ART nonadherence. These findings support the need for screening and treating underlying AUDs. In order to meet HIV TasP goals, evidence-based strategies targeting AUDs are likely to directly improve ART adherence and indirectly improve overall individual health, HIV treatment engagement, and reduce transmission to sexual partners among this vulnerable and disproportionally affected population.

Abstract
Alcohol abuse is the most common and costly form of drug abuse in the United States. It is well known that alcohol abuse contributes to risky behaviors associated with greater incidence of human immunodeficiency virus (HIV) infections. As HIV has become a more chronic disease since the introduction of antiretroviral therapy, it is expected that alcohol use disorders will have an adverse effect on the health of HIV-infected patients. The biomedical consequences of acute and chronic alcohol abuse are multisystemic. Based on what is currently known of the comorbid and pathophysiological conditions resulting from HIV infection in people with alcohol use disorders, chronic alcohol abuse appears to alter the virus infectivity, the immune response of the host, and the progression of disease and tissue injury, with specific impact on disease progression. The combined insult of alcohol abuse and HIV affects organ systems, including the central nervous system, the immune system, the liver, heart, and lungs, and the musculoskeletal system. Here we outline the major pathological consequences of alcohol abuse in the HIV-infected individual, emphasizing its impact on immunomodulation, erosion of lean body mass associated with AIDS wasting, and lipodystrophy. We conclude that interventions focused on reducing or avoiding alcohol abuse are likely to be important in decreasing morbidity and improving outcomes in people living with HIV/AIDS.

Design and methods of a double blind randomized placebo-controlled trial of extended-release naltrexone for alcohol dependent and hazardous drinking prisoners with HIV who are transitioning to the community. Contemp Clin Trials 2013; 37:209-18.

Abstract
BACKGROUND HIV-infected prisoners have a high prevalence of alcohol use disorders and commonly relapse to alcohol soon after release to the community which is linked to high morbidity, poor antiretroviral therapy (ART) adherence and increased sexual risk-taking behaviors. Extended-release naltrexone (XR-NTX) effectively reduces relapse to alcohol in alcohol dependent persons, yet it remains unexamined among criminal justice system (CJS) populations transitioning to the community. METHODS A randomized double-blind, placebo-controlled trial of XR-NTX to improve HIV treatment outcomes via reducing relapse to alcohol use after prison release for HIV-infected hazardous drinking and alcohol dependent prisoners is discussed. RESULTS Acceptability of study participation is high with 86% of those referred who met eligibility criteria and 85% of those who were able to receive injections prior to release accepted injections, yet important implementation issues are identified and addressed during the study and are discussed in this paper. CONCLUSION Medication-assisted therapies for prevention of relapse to alcohol use for CJS populations transitioning to the community, especially for HIV-infected patients, are urgently needed in order to reduce alcohol relapse after release and improve HIV treatment outcomes and contribute to improved individual and public health.

Abstract
Globally, there are over 33 million persons living with HIV/AIDS resulting in 1.8 million deaths annually. While the rate of HIV transmission is slowing, it is estimated that 2.6 million new infections occur yearly [1]. In the United States, there are approximately 1.2 million living with HIV/AIDS, with 50,000 new HIV infections and 17,000 deaths from the disease annually [2]. For those who can obtain effective antiretroviral therapy (ART), HIV/AIDS has become a chronic disease with life expectancies over 30 years [3]. Research in the last 10 years has revealed the importance of alcohol in the HIV/AIDS epidemic. Alcohol use, in moderate or hazardous amounts, has been associated with increased acquisition of HIV infection, progression of HIV infection, deleterious effects on HIV treatment, and acceleration in the comorbidities of HIV infection [4–9]. Yet alcohol remains the “forgotten drug” of the HIV/AIDS epidemic [10].

Abstract
PURPOSE Little is known about the association of intimate partner violence (IPV) with specific HIV-treatment outcomes, especially among criminal justice (CJ) populations who are disproportionately affected by IPV, HIV, mental, and substance use disorders (SUDs) and are at high risk of poor post-release continuity of care. DESIGN/METHODOLOGY/APPROACH Mixed methods were used to describe the prevalence, severity, and correlates of lifetime IPV exposure among HIV-infected jail detainees enrolled in a novel jail-release demonstration project in Connecticut. Additionally, the effect of IPV on HIV treatment outcomes and longitudinal healthcare utilization was examined. FINDINGS Structured baseline surveys defined 49 percent of 84 participants as having significant IPV exposure, which was associated with female gender, longer duration since HIV diagnosis, suicidal ideation, having higher alcohol use severity, having experienced other forms of childhood and adulthood abuse, and homo/bisexual orientation. IPV was not directly correlated with HIV healthcare utilization or treatment outcomes. In-depth qualitative interviews with 20 surveyed participants, however, confirmed that IPV was associated with disengagement from HIV care especially in the context of overlapping vulnerabilities, including transitioning from CJ to community settings, having untreated mental disorders, and actively using drugs or alcohol at the time of incarceration. ORIGINALITY/VALUE Post-release interventions for HIV-infected CJ populations should minimally integrate HIV secondary prevention with violence reduction and treatment for SUDs.

Abstract
OBJECTIVE To systematically review factors associated with HIV disease progression among illicit drug users, focusing on exposures exogenous to individuals that likely shape access and adherence to HIV treatment. DESIGN A systematic review of peer-reviewed English-language studies among HIV-seropositive illicit drug users with at least one of these endpoint of interest: a diagnosis of AIDS; death; changes/differences in CD4 cell counts; or changes/differences in plasma HIV-1 RNA levels. METHODS Articles were included if they reported factors associated with an outcome of interest among a group of illicit drug users. Studies were identified, screened and selected using systematic methods. RESULTS Of 2668 studies matching the search criteria, 58 (2%) met the inclusion criteria, all but one from North America or western Europe. Overall, 41 (71%) studies contained significant individual-level clinical characteristics or behaviors (e.g. illicit drug use) associated with disease progression. Fifteen studies (26%) identified significant social, physical, economic or policy-level exposures, including incarceration, housing status or lack of legal income. CONCLUSION Although past studies demonstrate important environmental exposures that appear to shape access to care and subsequent disease progression, the limited literature to examine these factors demonstrates the need for future research to consider risk environment characteristics and the role they may play in shaping health outcomes from HIV infection among drug users through determining access and adherence to evidence-based care.

Abstract
The incarcerated population has increased to unprecedented levels following the 1970 US declaration of war on illicit drug use. A substantial proportion of people with or at risk for HIV infection, including those with substance use and mental health disorders, have become incarcerated. The overlapping epidemics of incarceration and HIV present a need for academic medical centers to collaborate with the criminal justice system to improve the health of incarcerated populations. With coordinated collaboration and new programmatic initiatives it is possible to reduce HIV-associated risk behaviors and the likelihood of acquisition and transmission of HIV. Centers for AIDS Research (CFAR), funded by the National Institutes of Health, have proactively responded to this need through Collaboration on HIV in Corrections (CHIC) to improve the diagnosis, treatment, linkage to care, and prevention of HIV. This collaboration serves as a model for aligning academic expertise with criminal justice to confront this challenge to individual and public health. This is especially relevant given recent evidence of the effectiveness of antiretroviral therapy in reducing HIV transmission.

Abstract
The criminal justice system bears a disproportionate burden of the HIV epidemic. Continuity of care is critical for HAART-based prevention of HIV-related morbidity and mortality. This paper describes four major challenges to successful management of HIV in the criminal justice system: relapse to substance use, homelessness, mental illness, and loss of medical and social benefits. Each of these areas constitutes a competing priority upon release that demands immediate attention and diverts time, energy, and valuable resources away from engagement in care and adherence to HAART. Numerous gaps exist in scientific knowledge about these issues and potential solutions. In illuminating these knowledge deficits, we present a contemporary research agenda for the management of HIV in correctional systems. Future empirical research should focus on these critical issues in HIV-infected prisoners and releasees while interventional research should incorporate evidence-based solutions into the criminal justice setting.

Abstract
BACKGROUND Although some studies have identified impressive clinical gains for incarcerated HIV-seropositive injection drug users (IDUs) undergoing antiretroviral therapy (ART), the effect of incarceration on adherence to ART remains undetermined. METHODS We used data from a long-term community-recruited cohort of HIV-seropositive IDUs, including comprehensive ART dispensation records, in a setting where HIV care is free. We estimated the relationship between the cumulative burden of incarceration, measured longitudinally, and the odds of < 95% adherence to ART, with use of multivariate modeling. RESULTS From 1996 through 2008, 490 IDUs were recruited and contributed 2220 person-years of follow-up; 271 participants (55.3%) experienced an incarceration episode, with the number of incarcerations totaling 1156. In a multivariate model, incarceration had a strong dose-dependent effect on the likelihood of nonadherence to ART: 1-2 incarceration events (adjusted odds ratio [AOR], 1.49; 95% confidence interval [95% CI], 1.03-2.05), 3-5 events (AOR, 2.48; 95% CI, 1.62-3.65), and > 5 events (AOR, 3.11; 95% CI, 1.86-4.95). CONCLUSIONS Among HIV-seropositive IDUs receiving ART, an increasing burden of incarceration was associated with poorer adherence in a dose-dependent fashion. Our findings support improved adherence support for HIV-seropositive IDUs experiencing incarceration.

Abstract
OBJECTIVE This study was part of a national, multisite demonstration project evaluating the impact of integrated buprenorphine/naloxone treatment and HIV care. The goals of this study were to describe the baseline demographic, clinical, and substance use characteristics of the participants and to explore HIV transmission risk behaviors in this group. METHODS Nine sites across the United States participated. Data obtained by interview and chart review included demographic information, medical history, substance use, and risk behaviors.We performed a descriptive analysis of patient characteristics at entry and used logistic regression to evaluate factors associated with 1) unprotected anal or vaginal sex; and 2) needle-sharing within the previous 90 days. RESULTS Three hundred eighty-six individuals were included in the study: 303 (78.5%) received buprenorphine/naloxone; 41 (10.6%) received methadone; and 42 (10.9%) received another form of treatment. The analysis of risk behaviors was limited to those in the buprenorphine group (n = 303). Among those reporting vaginal or anal sex in the previous 90 days, 24% had sex without a condom. Factors significantly associated with unprotected sex were: having a partner; female gender; and alcohol use in previous 30 days. A total of 8.9% of participants shared needles in the previous 90 days. Factors significantly associated with needle-sharing were: amphetamine use; marijuana use; homelessness; and anxiety. CONCLUSIONS Addressing transmission risk behaviors is an important secondary HIV prevention strategy. In addition to treatment for opioid dependence, addressing other substance use, social issues, particularly housing, and mental health may have important implications for reducing HIV transmission in HIV-infected opioid-dependent patients.

Abstract
BACKGROUND People with both HIV and alcohol use disorders (AUDs) are disproportionately concentrated within the U.S. criminal justice system; approximately one-quarter of all people with HIV cycle through the system each year. HIV-infected prisoners with AUDs face many obstacles as they transition back to the community. Specifically, although they have impressive HIV treatment outcomes during the period of incarceration while they are free from alcohol; upon [corrected] release, however, they face inordinate challenges including relapse to alcohol use resulting in significant morbidity and mortality. OBJECTIVE To review the existing literature regarding the relationship of HIV and treatment for AUDs within the criminal justice system in an effort to determine "best practices" that might effectively result in improved treatment of HIV and AUDs for released prisoners. METHODS PubMed, PsychInfo and Medline were queried for articles published in English from 1990 to 2009. Selected references from primary articles were also examined. RESULTS Randomized controlled trials affirm the role of pharmacotherapy using naltrexone (NTX) as the therapeutic option conferring the best treatment outcome for AUDs in community settings. Absent from these trials were inclusion of released prisoners or HIV-infected individuals. Relapse to alcohol abuse among HIV-infected prisoners is associated with reduced retention in care, poor adherence to antiretroviral therapy with consequential poor HIV treatment outcomes and higher levels of HIV risk behaviors. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE Untreated alcohol dependence, particularly for released HIV-infected prisoners, has negative consequences both for the individual and society and requires a concentrated effort and rethinking of our existing approaches for this vulnerable population.

Abstract
BACKGROUND Alcohol use disorders (AUDs) are highly prevalent and associated with non-adherence to antiretroviral therapy, decreased health care utilization and poor HIV treatment outcomes among HIV-infected individuals. OBJECTIVES To systematically review studies assessing the impact of AUDs on: (1) medication adherence, (2) health care utilization and (3) biological treatment outcomes among people living with HIV/AIDS (PLWHA). DATA SOURCES Six electronic databases and Google Scholar were queried for articles published in English, French and Spanish from 1988 to 2010. Selected references from primary articles were also examined. REVIEW METHODS Selection criteria included: (1) AUD and adherence (N=20); (2) AUD and health services utilization (N=11); or (3) AUD with CD4 count or HIV-1 RNA treatment outcomes (N=10). Reviews, animal studies, non-peer reviewed documents and ongoing studies with unpublished data were excluded. Studies that did not differentiate HIV+ from HIV- status and those that did not distinguish between drug and alcohol use were also excluded. Data were extracted, appraised and summarized. DATA SYNTHESIS AND CONCLUSIONS Our findings consistently support an association between AUDs and decreased adherence to antiretroviral therapy and poor HIV treatment outcomes among HIV-infected individuals. Their effect on health care utilization, however, was variable.

Abstract
OBJECTIVE: To determine if significant differences exist in substance use among people living with HIV/AIDS (PLWHA) before and after establishing their HIV infection status. METHOD: The study participants are HIV positive clients of a community based HIV/AIDS outreach facility located in Montgomery, Alabama. The questionnaire includes demographics, substance use and risky sexual behaviors pertaining to HIV transmission. Each participant completed an anonymous questionnaire. A total of 341 questionnaires were distributed and 326 were fully completed and returned, representing a response rate of 96%. RESULTS: Findings revealed a statistically significant difference in alcohol consumption before sex among PLWHA before and after establishing their HIV infection status (p = .001). No significant differences were observed among participants who reported as having used drugs intravenously (p = .89), and among those sharing the same syringe/needle with another person (p = .87) before and after establishing their HIV infection status. CONCLUSION: There is continued substance use and alcohol consumption before sex among PLWHA after establishing their HIV status despite clear evidence of such risky behaviors that could lead to an increase in exposure to HIV.

Abstract
OBJECTIVES Risk factors for human immunodeficiency virus (HIV) disease progression among American Indians (AIs) have been poorly characterized. We assessed the impact of socioeconomic factors and use of traditional healing on HIV disease progression in a rural AI community. METHODS From January 2004 through December 2006, we interviewed 36 HIV-positive AIs regarding their socioeconomic status, incarceration, and use of traditional healing. We also collected chart-abstracted adherence and substance-abuse data. Through bivariate analysis, we compared these factors with the CD4-cell counts and log HIV-1 viral loads (VLs). Using a simple regression model, we assessed interactions between the significant associations and the outcome. RESULTS Participant characteristics included being male (58.3%), being transgender (13.9%), having ever been incarcerated (63.9%), having a household income of < $1,000/month (41.7%), being unemployed (61.1%), being diagnosed with alcohol abuse (50.0%), and using traditional medicine (27.8%) in the last 12 months. Higher VLs were associated with recent incarceration (p < 0.05), household income of < $1,000/month (p < 0.05), and provider-assessed alcohol abuse (p < 0.05). We found an interaction between incarceration and alcohol abuse, and alcohol abuse was the factor more strongly associated with higher VLs. A lower CD4 count was associated with recent incarceration (p < 0.05) and use of traditional medicine (p < 0.05). CONCLUSIONS Alcohol abuse is an important contributor to HIV disease progression, and participants with lower CD4 counts were more likely to use traditional medicine. HIV care among this rural AI population should focus on addressing alcohol abuse and other socioeconomic risk factors and promote collaboration between Western medical and Navajo traditional practitioners.

Abstract
We conducted a meta-analysis of studies assessing adherence to highly active antiretroviral therapy (HAART) and a qualitative systematic review of factors associated with better HAART outcomes among HIV+ drug users (DU). Thirty-eight studies were considered, which analyzed 14,960 patients (11,394 HIV+ DU, 76.2%). Overall adherence (pooled percent of DU classified as adherent in each study) was 0.60 (95% CI: 0.52-0.68), similar to levels identified by studies conducted with HIV+ patients who are not drug users. Time frame used to measure adherence was an independent predictor of inter-study heterogeneity. The systematic review identified better HAART outcomes among former DU, those with less severe psychiatric conditions, those receiving opioid substitution therapy and/or psychosocial support. Patients initiating HAART with lower viral load and higher CD4 counts, and those without co-infections also had better treatment outcomes. Our findings suggest that HIV+ DU tend to be inappropriately assumed to be less adherent and unlikely to achieve desirable treatment outcomes, when compared to their non-DU cohort.

Abstract
HIV-infected drug users have increased age-matched morbidity and mortality compared with HIV-infected people who do not use drugs. Substance-use disorders negatively affect the health of HIV-infected drug users, who also have frequent medical and psychiatric comorbidities that complicate HIV treatment and prevention. Evidence-based treatments are available for the management of substance-use disorders, mental illness, HIV and other infectious complications such as viral hepatitis and tuberculosis, and many non-HIV-associated comorbidities. Tuberculosis co-infection in HIV-infected drug users, including disease caused by drug-resistant strains, is acquired and transmitted as a consequence of inadequate prescription of antiretroviral therapy, poor adherence, and repeated interfaces with congregate settings such as prisons. Medication-assisted therapies provide the strongest evidence for HIV treatment and prevention efforts, yet are often not available where they are needed most. Antiretroviral therapy, when prescribed and adherence is at an optimum, improves health-related outcomes for HIV infection and many of its comorbidities, including tuberculosis, viral hepatitis, and renal and cardiovascular disease. Simultaneous clinical management of multiple comorbidities in HIV-infected drug users might result in complex pharmacokinetic drug interactions that must be adequately addressed. Moreover, interventions to improve adherence to treatment, including integration of health services delivery, are needed. Multifaceted, interdisciplinary approaches are urgently needed to achieve parity in health outcomes in HIV-infected drug users.

Abstract
We evaluated the association of alcohol consumption and depression, and their effects on HIV disease progression among women with HIV. The study included 871 women with HIV who were recruited from 1993-1995 in four US cities. The participants had physical examination, medical record extraction, and venipuncture, CD4+T-cell counts determination, measurement of depression symptoms (using the self-report Center for Epidemiological Studies-Depression Scale), and alcohol use assessment at enrollment, and semiannually until March 2000. Multilevel random coefficient ordinal models as well as multilevel models with joint responses were used in the analysis. There was no significant association between level of alcohol use and CD4+ T-cell counts. When participants were stratified by antiretroviral therapy (ART) use, the association between alcohol and CD4+ T-cell did not reach statistical significance. The association between alcohol consumption and depression was significant (p<0.001). Depression had a significant negative effect on CD4+ T-cell counts over time regardless of ART use. Our findings suggest that alcohol consumption has a direct association with depression. Moreover, depression is associated with HIV disease progression. Our findings have implications for the provision of alcohol use interventions and psychological resources to improve the health of women with HIV.

Abstract
BACKGROUND Alcohol use is frequently implicated as a factor in nonadherence to highly active antiretroviral therapy (HAART). There have not been efforts to systematically evaluate findings across studies. This meta-analysis provides a quantitative evaluation of the alcohol-adherence association by aggregating findings across studies and examining potential moderators. METHODS Literature searches identified 40 qualifying studies totaling over 25,000 participants. Studies were coded on several methodological variables. RESULTS In the combined analysis, alcohol drinkers were approximately 50%-60% as likely to be classified as adherent [odds ratio (OR) = 0.548, 95% confidence interval (CI): 0.490 to 0.612] compared with abstainers (or those who drank relatively less). Effect sizes for problem drinking, defined as meeting the National Institute on Alcohol Abuse and Alcoholism criteria for at-risk drinking or criteria for an alcohol use disorder, were greater (OR = 0.474, 95% CI = 0.408 to 0.550) than those reflecting any or global drinking (OR = 0.604, 95% CI = 0.531 to 0.687). Several variables moderated the alcohol-adherence association. CONCLUSIONS Results support a significant and reliable association of alcohol use and medication nonadherence. Methodological variables seem to moderate this association and could contribute to inconsistent findings across studies. Future research would benefit from efforts to characterize theoretical mechanisms and mediators and moderators of the alcohol-adherence association.

Abstract
INTRODUCTION HIV-positive injection drug users (IDU) often do not derive the full benefits of highly active antiretroviral therapy (HAART). Among IDU, recent incarceration has been associated with discontinuation of HAART for non-clinical reasons. We sought to qualitatively evaluate experiences with HAART among HIV-positive IDU who had been recently incarcerated within provincial prisons in British Columbia in order to identify factors influencing adherence to treatment. METHODS Twelve in-depth qualitative interviews were conducted with males recruited from a cohort study (ACCESS) involving over 450 HIV-positive IDU. All participants had been incarcerated after initiating HAART. Audio-recorded interviews were conducted to examine experiences of taking HAART in prison, with particular attention to adherence and experiences of treatment discontinuation. FINDINGS Participant accounts described situations where adherence to HIV treatment was compromised in custody. A small number of participants reported treatment interruptions that lasted over a week when they were unable to obtain HIV medications through institutional healthcare. Short-term interruptions in treatment were said to be common during intake into the correctional system and at the point of release from custody. High levels of HIV discrimination motivate prisoners to hide the fact that they are HIV-positive by making efforts to take medications discreetly, which may result in missed doses. CONCLUSIONS The current study identified contextual factors within correctional environments that hinder individuals' ability to adhere to HAART. These findings also indicate that improved health services and coordination with community care providers are needed to enhance the quality of HIV treatment within correctional environments.

Abstract
Alcohol use has negative effects on HIV disease progression through several mechanisms, including transmission, viral replication, host immunity, and treatment efficacy. Research with animal models has explored the effect of alcohol intake on several aspects of simian immunodeficiency virus (SIV) disease progression. Data suggest that the increased SIV levels observed in alcohol-consuming animals may represent an increase in virus production as opposed to a decrease in host defense. Results also suggest that changes in nutritional balance and metabolism, as a possible consequence of a proinflammatory state, together with increased virus production in animals consuming alcohol, accelerate SIV and possibly HIV disease progression. Further studies using the animal model are necessary.

Abstract
OBJECTIVES The aim of the study was to determine the relationship between alcohol consumption and liver fibrosis as assessed by aspartate aminotransferase to platelet ratio index (APRI) in HIV-infected adults and to explore the relative contributions of alcohol and hepatitis C virus (HCV) to APRI among HIV/HCV-coinfected adults. METHODS We performed a cross-sectional analysis of data from an observational clinical cohort. Alcohol consumption was categorized according to National Institute on Alcohol Abuse and Alcoholism guidelines. We defined significant liver disease as APRI>1.5, and used multinomial logistic regression to identify correlates of increased APRI. RESULTS Among 1358 participants, 10.4% reported hazardous drinking. It was found that 11.6% had APRI>1.5, indicating liver fibrosis. Hazardous drinking was associated with increased APRI [adjusted relative risk ratio (RRR) 2.30; 95% confidence interval (CI) 1.26-4.17]. Other factors associated with increased APRI were male gender, viral hepatitis, and HIV transmission category of injecting drug use. Among coinfected individuals, 18.3% had APRI>1.5, and hazardous drinking was not associated with APRI. Among non-HCV-infected individuals, 5.3% had APRI>1.5 and hazardous drinking was associated with increased APRI (adjusted RRR 3.72; 95% CI 1.40-9.87). CONCLUSIONS Hazardous drinking is an important modifiable risk factor for liver fibrosis, particularly among non-HCV-infected patients. Clinicians and researchers must address alcohol use as the burden of liver disease increases among HIV-positive individuals.

Abstract
AIMS Adherence to highly active antiretroviral therapy (HAART) is a key predictor of survival for human immunodeficiency virus (HIV)-infected people. Suboptimal adherence among marginalized populations such as HIV-positive drug users could be associated with clinical failure and the emergence of viral resistance. OBJECTIVE To conduct a systematic review of studies assessing adherence to HAART among HIV-positive drug users (DU) and identify factors associated with non-adherence to HIV treatment. DATA SOURCES Seven electronic databases were searched for peer-reviewed papers published in English, French, Spanish or Portuguese, from 1996 to 2007. STUDY SELECTION AND DATA ABSTRACTION Studies were excluded if they presented only qualitative data, were reviews themselves or assessed other populations without disaggregating data on DU. Findings on adherence were extracted and summarized. DATA SYNTHESIS Forty-one studies were considered, which studied a total of 15 194 patients, the majority of whom were HIV-positive DU (n = 11 628, 76.5%). Twenty-two studies assessed adherence using patient self-reports, eight used pharmacy records, three used electronic monitoring [i.e. Medication Event Monitoring Systems (MEMS) caps], six studies used a combination of patient self-report, clinical data and MEMS-caps, and two analyzed secondary data. Overall, active substance use was associated with poor adherence, as well as depression and low social support. Higher adherence was found in patents receiving care in structured settings (e.g. directly observed therapy) and/or drug addiction treatment (especially substitution therapy). CONCLUSION While lower than other populations-especially among users of stimulants, incarcerated DU and patients with psychiatric comorbidities-adherence to HAART among HIV-positive DU can be achieved. Better adherence was identified among those engaged in comprehensive services providing HIV and addiction treatment with psychosocial support.

Abstract
Globally, injection drug use continues to account for a substantial proportion of HIV infections. There have not, however, been any evidence-based reviews of the barriers and facilitators of HIV treatment among injection drug users. For this review, published studies were extracted from nine academic databases, with no language or date specified in the search criteria. Existing evidence demonstrates that, although injection drug users often have worse outcomes from HIV treatment than non-injection drug users, major antiretroviral-associated survival gains still have been observed among this population. Inferior outcomes are explained by a range of barriers to antiretroviral access and adherence, which often stem from the negative influences of illicit drug policies, as well as issues within medical systems, including lack of physician education about substance abuse. Evidence demonstrates that several under-utilized interventions and novel antiretroviral delivery modalities have helped to greatly address these barriers in several settings, and there is sufficient evidence to support immediate scale-up of these programmes. These interventions include coupling antiretroviral therapy with opioid substitution therapies as well as directly administered antiretroviral therapy programmes. Of particular interest for future evaluation is the coupling of HIV treatment programmes within comprehensive services, which also provide low-threshold (harm reduction) HIV prevention programmes. Scale-up of evidence-based HIV treatment and prevention to injection drug users, however, will require increasing political will among both national policy-makers and international public health agencies.

Abstract
OBJECTIVE We examined the independent effect of alcohol and combined effects of drug and alcohol use on antiretroviral (ART) utilization, adherence, and viral suppression in an urban cohort of HIV-infected individuals. METHODS In an observational clinical cohort, alcohol use, active drug use, and adherence were prospectively assessed at 6-month intervals. We classified hazardous alcohol use as >7 drinks/week or >3 drinks/occasion in women, and >14 drinks/week or >4 drinks/occasion in men and active drug use as any use in the previous 6 months. Our outcomes included ART utilization, 2-week adherence, and viral suppression. We used generalized estimating equations to analyze the association between independent variables and outcomes. Analyses were adjusted for age, sex, race, years on ART, and clinic enrollment time. RESULTS Between 1998 and 2003, 1711 individuals participated in 5028 interviews. 1433 of these individuals received ART accounting for 3761 interviews. The prevalence of any alcohol use at the first interview was 45%, with 10% classified as hazardous drinkers. One-third of the sample used illicit drugs. In multivariate analyses adjusting for age, sex, race, active drug use, years on ART, and clinic enrollment time, hazardous alcohol use was independently associated with decreased ART utilization (AOR, 0.65; 95% CI: 0.51 to 0.82), 2-week adherence (AOR, 0.46; 95% CI: 0.34 to 0.63), and viral suppression (AOR, 0.76; 95% CI: 0.57 to 0.99) compared to no alcohol use. Concurrent injection drug use (IDU) exacerbated this negative effect on ART use, adherence, and suppression. CONCLUSIONS Hazardous alcohol use alone and combined with IDU was associated with decreased ART uptake, adherence, and viral suppression. Interventions targeting alcohol use may improve HIV outcomes in individuals with hazardous alcohol use.

Abstract
OBJECTIVE We examined the association of methadone maintenance therapy (MMT) with highly active antiretroviral therapy (HAART) adherence and HIV treatment outcomes among a cohort of HIV/HCV co-infected injection drug users (IDUs). METHODS We obtained demographic, drug use, and addiction care history from the Vancouver Injection Drug User Study (VIDUS), which is an open cohort study of IDUs. The questionnaires were longitudinally linked to the British Columbia HIV/AIDS Drug Treatment Program to obtain HAART adherence and HIV treatment outcome data. There were 278 VIDUS participants who accessed HAART from August 1, 1996 to November 24, 2003. We constructed longitudinal logistic models using generalized estimating equations to examine the independent associations between methadone maintenance therapy and the following outcomes: HAART adherence; plasma HIV-1 RNA suppression; and CD4 cell rise of 100cells/mm(3). RESULTS Among participants who reported at least weekly heroin use, MMT was independently associated with lower odds of subsequent weekly heroin use during the follow-up period (adjusted odds ratio; 95% confidence interval [AOR; 95% CI]: 0.24; 0.14-0.40). We also found that MMT was positively associated with adherence (AOR 1.52; 95% CI 1.16-2.00), HIV-1 RNA suppression (AOR 1.34; 95% CI 1.00-1.79), and CD4 cell count rise (AOR 1.58; 95% CI 1.26-1.99). CONCLUSIONS Among HIV/HCV co-infected IDUs on HAART, enrollment in MMT was associated with reduced heroin use, and improved adherence, HIV-1 RNA suppression and CD4 cell count response. Integrating opiate addiction care and HIV care may provide improved health outcomes for this vulnerable population and should be further explored.

Abstract
There is a high prevalence of substance abuse and psychiatric disorders among HIV-infected individuals. Importantly, drug and alcohol-use disorders are frequently co-morbid with depression, anxiety and severe mental illness. Not only do these disorders increase the risk of contracting HIV, they have also been associated with decreased highly active antiretroviral therapy (HAART) utilisation, adherence and virological suppression. The literature evaluating the relationship between substance abuse and HIV outcomes has primarily focused on injection drug users, although there has been increasing interest in alcohol, cocaine and marijuana. Similarly, the mental health literature has focused largely on depression, with a lesser focus on severe mental illness or anxiety. To date, there is little literature evaluating the association between co-occurring HIV, substance abuse and mental illness on HAART uptake, adherence and virological suppression. Adherence interventions in these populations have demonstrated mixed efficacy. Both directly observed therapy and pharmacist-assisted interventions appear promising, as do integrated behavioural interventions. However, the current intervention literature has several limitations: few of these studies are randomised, controlled trials; the sample sizes have generally been small; and co-occurring substance abuse and mental illness has not specifically been targeted in these studies. Future studies examining individual substances of abuse, psychiatric disorders and co-occurring substance abuse and psychiatric disorders on HIV outcomes will inform targeted adherence interventions.
