Abstract
The leading cause of non-HIV-related mortality is liver disease. Fatty liver disease can be characterized as alcoholic or nonalcoholic in nature. Alcohol use is prevalent among individuals with HIV infection and can lead to medication nonadherence, lower CD4+ cell count, inadequate viral suppression, and disease progression. The pathogenesis of nonalcoholic fatty liver disease (NAFLD) in individuals with HIV infection includes metabolic syndrome, hyperuricemia, HIV-related lipodystrophy, genetic polymorphisms, medications, HIV itself, and the gut microbiome. The prevalence of NAFLD in persons with HIV infection ranges from 30% to 65% depending on the modality of diagnosis. Individuals with HIV infection and NAFLD are at higher risk of cardiovascular disease; however, there is a dearth of longitudinal outcomes studies on this topic. Current therapies for NAFLD, such as vitamin E and pioglitazone, have not been studied in persons with HIV infection. There are several drugs in phase II and III clinical trials that specifically target NAFLD in HIV, including CC chemokine receptor 5 inhibitors, growth hormone-releasing factor agonists, and stearoyl-CoA desaturase inhibitors. Persons with HIV should be screened for NAFLD while pursuing aggressive risk factor modification and lifestyle changes, given the increased risk of cardiovascular mortality.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) infection and heavy drinking independently promote microbial translocation and inflammation. However, it is not known how alcohol use may affect these processes in people living with HIV (PLWH). This study tested the hypothesis that alcohol exacerbates innate immune dysfunction in PLWH. METHODS Participants were 75 PLWH and 34 uninfected controls. Groups were recruited to have similar proportions of nondrinkers, moderate drinkers, and heavy drinkers. Substance use data and plasma samples were collected at up to 3 visits over a 5-year study period. Recent alcohol use was assessed with the Timeline Followback Interview. Biomarkers of microbial translocation (lipopolysaccharide, LPS) and immune activation (lipopolysaccharide binding protein, LBP; soluble CD14, sCD14; soluble CD163, sCD163) were quantified using enzyme-linked immunosorbent assays. Analyses tested 2 hypotheses: (i) that biomarker levels would be significantly higher in PLWH than controls with comparable alcohol use and (ii) that current alcohol use would exacerbate biomarker elevations in PLWH. The second analysis included the interaction of alcohol use with hepatitis C virus (HCV) coinfection. RESULTS Groups were matched on alcohol use, smoking, and other drug use. All biomarkers were significantly higher in PLWH relative to controls (LBP: p = 0.005; LPS: p = 0.014; sCD14: p < 0.001; sCD163: p < 0.001). In PLWH, alcohol use showed a significant, positive association with sCD163, but not with other biomarkers. However, the interaction of alcohol use with HCV coinfection was significant for all biomarkers (LBP: p = 0.002; LPS: p = 0.026; sCD14: p = 0.0004; sCD163: p = 0.001). In pairwise tests with sequential Bonferroni correction, HIV/HCV coinfected individuals who drank heavily had significantly higher sCD163 compared to coinfected nondrinkers and to HIV monoinfected nondrinkers, moderate drinkers, and heavy drinkers (ps < 0.005). Coinfected moderate drinkers had significantly higher sCD163 than each monoinfected group (ps < 0.003). In addition, sCD14 was significantly higher in coinfected moderate drinkers than coinfected nondrinkers (p = 0.027). CONCLUSIONS As predicted, PLWH had higher levels of LBP, LPS, sCD14, and sCD163 than uninfected individuals with similar alcohol use. In PLWH, alcohol by itself was significantly associated only with higher sCD163. However, heavy or moderate alcohol use was associated with elevations in macrophage activation (sCD163) and monocyte activation (sCD14) in HIV/HCV coinfected individuals.

Abstract
Alcohol use may have significant negative impacts on individuals' ability to remain adherent to antiretroviral therapy (ART), and may also yield other negative psychosocial, health-related, and behavioral outcomes. In addition, false beliefs about the consequences of mixing alcohol with ART use may cause individuals to avoid taking ART when drinking (alcohol-related ART avoidance). Although research conducted in the U.S. and Europe has reported on alcohol-ART avoidance, the current study presents among the first quantitative evidence of alcohol-related intentional ART nonadherence in South Africa. Patients receiving ART from a community clinic in Cape Town (N = 441) completed anonymous surveys of alcohol use, ART adherence, and alcohol-ART avoidance. Results showed that 292 (66%) participants reported current alcohol use; 25% who use alcohol believed that people who drink should stop taking ART when they are drinking and 24% stop their own ART when drinking. Alcohol-ART avoidance mediated the association between alcohol use and ART adherence. Results were robust when controlling for participant age, gender, current care status, and first- versus second-line ART. We found alcohol-ART avoidance may threaten successful ART in South Africa. Corrective messages that take a harm reduction approach to maximize ART adherence when drinking should be implemented in existing clinical services.

Abstract
Little is known about disparities in depression prevalence, treatment, and remission by psychiatric comorbidities and substance use among persons living with HIV (PLWH). We conducted a cross-sectional analysis in a large cohort of PLWH in routine care and analyzed conditional probabilities of having an indication for depression treatment, receiving treatment, receiving indicated treatment adjustments, and achieving remission, stratified by alcohol use, illicit drug use, and panic symptoms. Overall, 34.7% (95% CI 33.9-35.5%) of participants had an indication for depression treatment and of these, 55.3% (53.8-56.8%) were receiving antidepressants. Among patients receiving antidepressants, 33.0% (31.1-34.9%) had evidence of remitted depression. In a subsample of sites with antidepressant dosage data, only 8.8% (6.7-11.5%) of patients received an indicated treatment adjustment. Current drug users (45.8%, 95% CI 43.6-48.1%) and patients reporting full symptoms of panic disorder (75.0%, 95% CI 72.9-77.1%) were most likely to have an indication for antidepressant treatment, least likely to receive treatment given an indication (current drug use: 47.6%, 95% CI 44.3-51.0%; full panic symptoms: 50.8%, 95% CI 48.0-53.6%), or have evidence of remitted depression when treated (22.3%, 95% CI 18.5-26.6%; and 7.3%, 95% CI 5.5-9.6%, respectively). In a multivariable model, drug use and panic symptoms were independently associated with poorer outcomes along the depression treatment cascade. Few differences were evident by alcohol use. Current drug users were most likely to have an indication for depression treatment, but were least likely to be receiving treatment or to have remitted depression. These same disparities were even more starkly evident among patients with co-occurring symptoms of panic disorder compared to those without. Achieving improvements in the depression treatment cascade will likely require attention to substance use and psychiatric comorbidities.

Abstract
The effect of non-injection substance use on HIV viral load (VL) is understudied in international settings. Data are from HPTN063, a longitudinal observational study of HIV-infected individuals in Brazil, Thailand, and Zambia, with focus on men with VL data (Brazil = 146; Thailand = 159). Generalized linear mixed models (GLMM) assessed whether non-injection substance use (stimulants, cannabis, alcohol, polysubstance) was associated with VL undetectability. ART adherence and depressive symptoms were examined as mediators of the association. In Thailand, substance use was not significantly associated with VL undetectability or ART adherence, but alcohol misuse among MSM was associated with increased odds of depression (AOR = 2.75; 95% CI 1.20, 6.32, p = 0.02). In Brazil, alcohol misuse by MSM was associated with decreased odds of undetectable VL (AOR = 0.34; 95% CI 0.13, 0.92, p = 0.03). Polysubstance use by heterosexual men in Brazil was associated with decreased odds of ART adherence (AOR = 0.25; 95% CI 0.08, 0.78, p = 0.02). VL suppression appears attainable among non-injection substance users. Substance use interventions among HIV-positive men should address depression, adherence, and VL undetectability.

Abstract
BACKGROUND Alcohol use has been shown to accelerate disease progression in experimental studies of simian immunodeficiency virus in macaques, but the results in observational studies of HIV have been conflicting. METHODS We conducted a prospective cohort study of the impact of unhealthy alcohol use on CD4 cell count among HIV-infected persons in southwestern Uganda not yet eligible for antiretroviral treatment (ART). Unhealthy alcohol consumption was 3-month Alcohol Use Disorders Identification Test-Consumption positive (≥3 for women, ≥4 for men) and/or phosphatidylethanol (PEth-an alcohol biomarker) ≥50 ng/mL, modeled as a time-dependent variable in a linear mixed effects model of CD4 count. RESULTS At baseline, 43% of the 446 participants were drinking at unhealthy levels and the median CD4 cell count was 550 cells/mm (interquartile range 416-685). The estimated CD4 cell count decline per year was -14.5 cells/mm (95% confidence interval: -38.6 to 9.5) for unhealthy drinking vs. -24.0 cells/mm (95% confidence interval: -43.6 to -4.5) for refraining from unhealthy drinking, with no significant difference in decline by unhealthy alcohol use (P value 0.54), adjusting for age, sex, religion, time since HIV diagnosis, and HIV viral load. Additional analyses exploring alternative alcohol measures, participant subgroups, and time-dependent confounding yielded similar findings. CONCLUSION Unhealthy alcohol use had no apparent impact on the short-term rate of CD4 count decline among HIV-infected ART naive individuals in Uganda, using biological markers to augment self-report and examining disease progression before ART initiation to avoid unmeasured confounding because of misclassification of ART adherence.

Abstract
This study sought to examine if age moderated the effect of alcohol on viral suppression among women living with HIV. A secondary data analysis, using data from the 550 Clinic Women's HIV Cohort Study was completed. Individuals were included if they were HIV positive, sought care in an urban clinic in Kentucky between 2009 and 2012, and had ≥1 year of follow-up. The primary independent variable was current alcohol use; the moderating variable was age (<50 years versus ≥50 years); and the outcome was suppression. Logistic regression models examined the interaction between age and alcohol. Among 360 women (average age 45.8 ± 10.1 years, 38 percent were ≥50 years), approximately 32.0 percent had consumed alcohol, and 40 percent achieved suppression. Women aged ≥50 years were more likely to achieve suppression than younger women. Age interacted significantly with alcohol (p = .038). Stratified by age, alcohol was associated with poor viral suppression among older women; for older women, alcohol users had lower odds of suppression compared to nonusers (odds ratio = 0.37; 95 percent confidence interval = 0.14-0.99). Alcohol may impede the opportunity for older women to achieve suppression. Further study is needed to examine alcohol use among older women, specifically addressing quantity and frequency and their impact on suppression.

Abstract
We evaluated associations between levels of alcohol use and HIV care continuum components using national Veterans Aging Cohort Study data for all patients with HIV and AUDIT-C screening (2/1/2008-9/30/2014). Poisson regression models evaluated associations between alcohol use levels (non-drinking, low-, medium-, high-, and very high-level drinking) and: (1) engagement with care (documented CD4 cells/µl or viral load copies/ml labs), (2) ART treatment (≥ 1 prescription), and (3) viral suppression (HIV RNA < 500 copies/ml) within one year. Among 33,224 patients, alcohol use level was inversely associated with all care continuum outcomes (all p < 0.001). Adjusted prevalence of care engagement ranged from 77.8% (95% CI 77.1-78.4%) for non-drinking to 69.1% (66.6-71.6%) for high-level drinking. The corresponding range for ART treatment was 74.0% (73.3-74.7%) to 60.1% (57.3-62.9%) and for viral suppression was 57.3% (56.5-58.1%) to 38.3% (35.6-41.1%). Greater alcohol use is associated with suboptimal HIV treatment across the HIV care continuum.

Abstract
We sought to test the efficacy of extended-release naltrexone (XR-NTX) on HIV-related and drinking outcomes. From April 2011-February 2015, we conducted a 4-site randomized double-blind placebo controlled clinical trial involving 51 HIV-positive patients with heavy drinking and < 95% antiretroviral (ART) adherence. All participants received counseling. The primary outcome was proportion with ≥ 95% ART adherence. Secondary outcomes included HIV biomarkers, VACS Index score, and past 30-day heavy drinking days. Based on receipt of ≥ 5 injections, 23 participants were retained at 24 weeks. We did not detect an effect of XR-NTX on ART adherence (p = 0.38); undetectable HIV viral load (p = 0.26); CD4 cell count (p = 0.75) or VACS Index score (p = 0.70). XR-NTX was associated with fewer heavy drinking days (p = 0.03). While XR-NTX decreases heavy drinking days, we did not detect improvements in ART adherence or HIV outcomes. Strategies to improve retention in alcohol treatment and HIV-related outcomes among heavy drinking HIV-positive patients are needed.

Abstract
In sub-Saharan Africa, harmful alcohol use among male drinkers is high and has deleterious consequences on adherence to antiretroviral therapy (ART), HIV clinical outcomes, and couple relationship dynamics. We conducted in-depth qualitative interviews with 25 Malawian couples on ART to understand how relationships influence adherence to ART, in which alcohol use emerged as a major theme. Almost half of men (40%) reported current or past alcohol use. Although alcohol use was linked to men's non-adherence, women buffered this harm by encouraging husbands to reduce alcohol use and by offering adherence support when men were drinking. Men's drinking interfered with being an effective treatment guardian for wives on ART and also weakened couple support systems needed for adherence. Relationship challenges including food insecurity, intimate partner violence, and extramarital relationships appeared to exacerbate the negative consequences of alcohol use on ART adherence. In this setting, alcohol may be best understood as a couple-level issue. Alcohol interventions for people living with HIV should consider approaches that jointly engage both partners.

Abstract
PURPOSE The use of opioids in patients with chronic non-cancer pain is common and can be associated with opioid-induced androgen deficiency (OPIAD) in men. This review aims to evaluate the current literature regarding the prevalence, clinical consequence and management of OPIAD. METHODS A database search was performed in Medline, Embase and Cochrane using terms such as "analgesics", "opioids" and "testosterone". Relevant literature from January 1969 to March 2018 was evaluated. RESULTS The prevalence of patients with OPIAD ranges from 19 to 86%, depending on the criteria for diagnosis of hypogonadism. The opioid-induced suppression of gonadotropin-releasing and luteinizing hormones represents the main important pathogenetic mechanisms. OPIAD has significant negative clinical consequences on sexual function, mood, bone density and body composition. In addition, OPIAD can also impair pain control leading to hyperalgesia, which can contribute to sexual dysfunction and mood impairment. CONCLUSIONS OPIAD is a common adverse effect of opioid treatment and contributes to sexual dysfunction, impairs pain relief and reduces overall quality of life. The evaluation of serum testosterone levels should be considered in male chronic opioid users and the decision to initiate testosterone treatment should be based on the clinical profile of individuals, in consultation with the patient.

Abstract
BACKGROUND For people living with HIV (PLWH), alcohol use is harmful and may be influenced by unique challenges faced by PLWH living in rural areas. We describe patterns of alcohol use across rurality among PLWH. METHODS Veterans Aging Cohort Study electronic health record data were used to identify patients with HIV (ICD-9 codes for HIV or AIDS) who completed AUDIT-C alcohol screening between February 1, 2008, and September 30, 2014. Regression models estimated and compared 4 alcohol use outcomes (any use [AUDIT-C > 0] and alcohol use disorder [AUD; ICD-9 codes for abuse or dependence] diagnoses among all PLWH, and AUDIT-C risk categories: lower- [1-3 men/1-2 women], moderate- [4-5 men/3-5 women], higher- 6-7]), and severe-risk [8-12], and heavy episodic drinking (HED; ≥1 past-year occasion) among PLWH reporting use) across rurality (urban, large rural, small rural) and census-defined region. FINDINGS Among 32,699 PLWH (29,540 urban, 1,301 large rural, and 1,828 small rural), both any alcohol use and AUD were highest in urban areas, although this varied across region. Predicted prevalence of any alcohol use was 54.1% (53.5%-54.7%) in urban, 49.6% (46.9%-52.3%) in large rural, and 50.6% (48.3%-52.9%) in small rural areas (P < .01). Predicted prevalence of AUD was 14.4% (14.0%-14.8%) in urban, 11.8% (10.0%-13.5%) in large rural, and 12.3% (10.8%-13.8%) in small rural areas (P < .01). Approximately 12% and 25% had higher- or severe-risk drinking and HED, respectively, but neither differed across rurality. CONCLUSION Though some variation across rurality and region was observed, alcohol-related interventions are needed for PLWH across all geographic locations.

Abstract
Ugandan fishing communities are dually burdened with high rates of HIV and alcohol use. This qualitative study explores context and motivation of alcohol consumption, and alcohol's effect on antiretroviral treatment (ART) adherence, among male fisherfolk living with HIV in Wakiso District, Uganda. We conducted in-depth semi-structured interviews with 30 men in HIV care and on ART, and used a thematic analysis approach for analysis. Alcohol use was identified as a major barrier to ART adherence through cognitive impairment and the intentional skipping of doses when drinking. Men reportedly reduced their drinking since HIV diagnosis - motivated by counseling received from providers and a newfound desire to live a healthy lifestyle. However, social, occupational, and stress-related influences that make alcohol reduction difficult were identified. Our findings suggest alcohol use may pose a challenge to ART adherence for fishermen living with HIV - and has implications for the tailoring of screening and brief intervention for alcohol reduction in HIV care for this population.

Changes in alcohol use associated with changes in HIV disease severity over time: A national longitudinal study in the Veterans Aging Cohort. Drug Alcohol Depend 2018; 189:21-29. [PMID: 29859388 PMCID: PMC6344121 DOI: 10.1016/j.drugalcdep.2018.04.022] [Citation(s) in RCA: 30] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2017] [Revised: 04/06/2018] [Accepted: 04/23/2018] [Indexed: 02/04/2023]
Abstract
BACKGROUND Among groups of persons living with HIV (PLWH), high-risk drinking trajectories are associated with HIV severity. Whether changes in individuals' alcohol use are associated with changes in HIV severity over the same period is unknown. METHODS Veterans Aging Cohort Study (VACS) data from VA's EHR (2/1/2008-9/30/2016) identified AUDIT-C screens for all PLWH. Pairs of AUDIT-C screens within 9-15 months were included if CD4 and/or viral load (VL) was measured within 9 months after baseline and follow-up AUDIT-Cs. Linear regression assessed change in HIV severity (CD4 and logVL) associated with AUDIT-C change adjusted for confounders. Mean changes in HIV severity were estimated for each AUDIT-C change value. For all measures of change, positive values indicate improvements (lower drinking and improved HIV severity). RESULTS Among PLWH, 21,999 and 22,143 were eligible for CD4 and VL analyses, respectively. Most had non- or low-level drinking and stable consumption over time (mean AUDIT-C change = .08, SD = 1.91). HIV severity improved over time [mean CD4 change = 20.5 (SD 180.8); mean logVL change = 0.12 (SD 0.71)]. AUDIT-C changes were associated non-linearly with changes in CD4 (p = 0.03) and logVL (p < 0.001). Improvement in HIV severity was greatest among those with stable AUDIT-C scores over time; those with greater AUDIT-C increases fared worse than those with smaller increases in or stable AUDIT-Cs. CONCLUSIONS Improvement in HIV severity was greatest among PLWH with relatively stable drinking, most of whom initially did not drink or drank at low levels. Those with large changes (especially increases) in drinking appear at greatest risk for poor HIV control.

Abstract
Our understanding of how community-level context impacts care of persons living with HIV (PLWH), including antiretroviral therapy (ART) adherence and retention in care, is limited. The objective of this study was to characterize the activity spaces of PLWH from an urban area in Southeastern U.S., where the epidemic is among the nation's highest, and to examine how such activity spaces are associated with daily mood and health behaviors. In this small, pilot study, 11 participants were tracked with a global positioning system (GPS)-enabled application on their smartphones for 2 weeks. Activity spaces were created by connecting GPS points sequentially and adding buffers. Contextual exposure data (e.g., alcohol outlets) were connected to activity spaces. Participants also completed daily diary entry through texts 3 times per day regarding outcomes of substance use behaviors, mood, and medication adherence. This yielded a total of 18,007 GPS polyline records that we aggregated into 258 person-days that captured discrete occasions of exposure to contextual factors and subjects' behaviors and moods. On average, the participants spent 19% of their time awake during the 2-week periods in their residential census tract. Exposure to social and built environment factors such as alcohol outlets was greater when participants were outside versus inside their residential census tract. Exposures on daily routes were also significantly associated with ART adherence, alcohol consumption, and mood. Findings suggest substantial differences between activity spaces and residential contexts. Activity spaces are relevant for PLWH and may impact HIV care and behavioral outcomes such as ART adherence and substance use.

Abstract
HIV disease continues to be a serious health issue all over the world. By the end of 2016, 36.7 million people were living with HIV, 1.8 million people became newly infected and 1 million died of HIV-related causes/diseases. In order to develop effective treatment strategies, is important to assess the risk factors that affect negatively the HIV-positive patients. HIV-infected patients are at high risk of developing psychiatric disorders in every stage of the illness. Psychiatric disorders can negatively influence the treatment adherence, induce risk behavior and influence the quality of life. The purpose of this study is to determine if the severity of HIV disease is associated with increased frequency of psychiatric disorders. We evaluated 101 HIV-positive patients receiving antiretroviral therapy in Western Romania via Psychiatric Diagnostic Screening Questionnaire (PDSQ). We conducted a risk analysis in order to see if the patients have a higher risk of developing psychiatric disorders depending on HIV serostatus factor (HIV asymptomatic, symptomatic, AIDS converted). Our study shows that, the patients having AIDS and symptomatic HIV have a higher prevalence for the most common psychiatric disorders: major depressive disorder (OR = 5.81;p < 0.001), panic disorder (OR = 3.11; p = 0.016), agoraphobia (OR = 4.31; p = 0.024), social phobia (OR = 2.81; p = 0.038), generalized anxiety disorder (OR = 4.79; p = 0.006), somatization (OR = 8.72; p < 0.0010) and hypochondria (OR = 4.66; p = 0.0013). Symptomatic HIV and AIDS converted serostatus is also a risk factor for post-traumatic stress disorder, obsessive-compulsive disorder and psychosis. The main conclusion of this study is that the more severe HIV clinical disease was associated with increased frequency of psychiatric disorders. As a consequence, we conclude that psychiatric disorders and HIV/AIDS treatment should be addressed simultaneously, depending on the risk specific factors such as the HIV infection stage and, due to psychiatric repercussions of HIV is expected to become more relevant in the coming years.

Abstract
Despite medical advancements that have significantly improved the health outcomes of people living with HIV (PLWH), many do not achieve optimal health outcomes due to psychosocial barriers. This 5-year retrospective longitudinal study draws upon the International Classification of Functioning, Disability, and Health (ICF) framework to conceptualize the relationships between personal and environmental factors and health and retention outcomes among a sample of 704 PLWH in Pennsylvania. A generalized estimated equations (GEE) model was used to model retention in care outcomes (at least one medical visit every 6 months) and a general linear mixed (GLM) model was used to analyze immune system health outcomes (CD4%). This exploratory study reveals that gender, age, race, use of antiretroviral (ARV) medications, use of case management service, mental health diagnosis, and alcohol use were significantly associated with retention in care, whereas race, ethnicity, gender, mental health treatment, use of ARV medications, use of case management services, and retention in care status were significantly associated with the immune system health outcome of CD4%. The results suggest a need for rehabilitation interventions to address key psychosocial issues, as rehabilitation counselors have a unique skill set to address the medical case management needs of individuals with HIV. Implications for rehabilitation counselors and educators are discussed.

Abstract
BACKGROUND Increasing alcohol use is associated with increased risk of mortality among patients living with HIV (PLWH). This association varies by race/ethnicity among general outpatients, but racial/ethnic variation has not been investigated among PLWH, among whom racial/ethnic minorities are disproportionately represented. METHODS VA electronic health record data from the Veterans Aging Cohort Study (2008-2012) were used to describe and compare mortality rates across race/ethnicity and levels of alcohol use defined by the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) questionnaire. Within each racial/ethnic group, Cox proportional hazards models, adjusted for age, disease severity, and comorbidities, compared mortality risk for moderate-risk (AUDIT-C = 4-7) and high-risk (AUDIT-C ≥ 8) relative to lower-risk (AUDIT-C = 1-3) alcohol use. RESULTS Mean follow-up time among black (n = 8518), Hispanic (n = 1353), and white (n = 7368) male PLWH with documented AUDIT-C screening (n = 17,239) was 4.3 years. Black PLWH had the highest mortality rate among patients reporting lower-risk alcohol use (2.9/100 person-years) relative to Hispanic and white PLWH (1.8 and 2.3, respectively) (p value for overall comparison = 0.011). Mortality risk was increased for patients reporting high-risk relative to lower-risk alcohol use in all racial/ethnic groups [black adjusted hazard ratio (AHR) = 1.36, 95% confidence interval (CI) 1.12-1.66; Hispanic AHR = 2.18, 95% CI 1.30-3.64; and white AHR = 2.04, 95% CI 1.61-2.58]. For only white PLWH, mortality risk was increased for patients reporting moderate-relative to lower-risk alcohol use (black AHR = 1.09, 95% CI 0.93-1.27; Hispanic AHR = 1.36, 95% CI 0.89-2.09; white AHR = 1.51, 95% CI 1.28-1.77). CONCLUSION Among all PLWH, mortality risk was increased among patients reporting high-risk alcohol use across all racial/ethnic groups, but mortality risk was only increased among patients reporting moderate-risk relative to lower-risk alcohol use among white PLWH, and black patients appeared to have higher mortality risk relative to white patients at lower-risk levels of alcohol use. Findings of the present study further underscore the need to address unhealthy alcohol use among PLWH, and future research is needed to understand mechanisms underlying observed differences.

Abstract
Human immunodeficiency virus (HIV) enters the brain early after infecting humans and may remain in the central nervous system despite successful antiretroviral treatment. Many neuroimaging techniques were used to study HIV+ patients with or without opportunistic infections. These techniques assessed abnormalities in brain structures (using computed tomography, structural magnetic resonance imaging (MRI), diffusion MRI) and function (using functional MRI at rest or during a task, and perfusion MRI with or without a contrast agent). In addition, single-photon emission computed tomography with various tracers (e.g., thallium-201, Tc99-HMPAO) and positron emission tomography with various agents (e.g., [18F]-dexoyglucose, [11C]-PiB, and [11C]-TSPO tracers), were applied to study opportunistic infections or HIV-associated neurocognitive disorders. Neuroimaging provides diagnoses and biomarkers to quantitate the severity of brain injury or to monitor treatment effects, and may yield insights into the pathophysiology of HIV infection. As the majority of antiretroviral-stable HIV+ patients are living longer, age-related comorbid disorders (e.g., additional neuroinflammation, cerebrovascular disorders, or other dementias) will need to be considered. Other highly prevalent conditions, such as substance use disorders, psychiatric illnesses, and the long-term effects of combined antiretroviral therapy, all may lead to additional brain injury. Neuroimaging studies could provide knowledge regarding how these comorbid conditions impact the HIV-infected brain. Lastly, specific molecular imaging agents may be needed to assess the central nervous system viral reservoir.

Abstract
Background Engaging people who drink alcohol or inject drugs in HIV care can be challenging, particularly in Eastern Europe. Healthcare facilities in Russia are organized by specialty; therefore linking patients from addiction care to HIV hospitals has been difficult. The HIV care cascade outlines stages of HIV care (e.g., linkage to care, prescribed antiretroviral therapy [ART], and achieving HIV viral suppression). We hypothesized that unhealthy alcohol use, injection drug use, and opioid craving are associated with unfavorable HIV care cascade outcomes. Methods We analyzed data from a cohort (n = 249) of HIV-positive Russians who have been in addiction hospital treatment in the past year and had a lifetime history of injection drug use (IDU). We evaluated the association between unhealthy alcohol use (AUDIT score > 7 [both hazardous drinking and dependence]), past-month injection drug use (IDU), and opioid craving (visual analogue scale from 1 to 100) with HIV care cascade outcomes. The primary outcome was linkage to HIV care within 12 months. Other outcomes were prescription of ART (secondary) and achievement of undetectable HIV viral load (HVL < 500 copies/mL) within 12 months (exploratory); the latter was analyzed on a subset in which HVL was measured (n = 48). We assessed outcomes via medical record review (linkage, ART) and serum tests (HVL). To examine the primary outcome, we used multiple logistic regression models controlling for potential confounders. Results Among 249 study participants, unhealthy alcohol use (n = 148 [59%]) and past-month IDU (n = 130 [52%]) were common. The mean opioid craving score was 49 (SD: 38). We were unable to detect significant associations between the independent variables (i.e., unhealthy alcohol use, IDU and opioid craving) and any HIV care cascade outcomes in unadjusted and adjusted analyses. Conclusion In this cohort of HIV-positive Russians with a history of IDU, individual substance use factors were not significantly associated with achieving HIV care cascade milestones (i.e., linkage to HIV care; prescription for ART; or suppressed viral load). Given no detection of an association of cascade outcomes with recent unhealthy use of alcohol or injection drugs in this cohort, examining systemic factors to understand determinants of HIV care engagement for people with drug use would be important.

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
Alcohol abuse can influence sexual risk behavior; however, its measurement is not straightforward. This study compared self-reported alcohol use, via the AUDIT and CAGE, with levels of phosphatidylethanol (Peth), a phospholipid biomarker that forms with chronic, heavy drinking, among high-risk MSM and TW in Lima, Peru. Chi square, Fisher's exact, Wilcoxon ranksum tests compared the instruments. Receiver operating curves determined sensitivity and specificity of the self-reported measures. Among 69 MSM and 17 TW, PEth was positive for 86% (95% CI 77-93%) of participants, while 67% reported binge-drinking in the last 2 weeks. The AUDIT classified 25% as hazardous drinkers while CAGE identified 6% as problem drinkers. Self-reported binge drinking was more sensitive than the AUDIT for PEth positivity (71% vs. 27%, p = 0.022). Among high-risk MSM and TW in Lima, validated, self-report measures of alcohol abuse underestimated biological measures. Further research correlating bio-markers and self-reported alcohol abuse measures is needed.

Abstract
Alcohol use can limit the effectiveness of antiretroviral therapy (ART) for people living with HIV (PLH) who have a history of injecting drug use. This study described the patterns of alcohol use among PLH with a history of injecting drug use in Vietnam and examined the relationships between alcohol use, adherence to ART, and sexual risks. We utilized cross-sectional data of 109 PLH on ART collected from a randomized controlled intervention trial in Vietnam. Approximately 30 and 46% of the participants were frequent and occasional drinkers, respectively. Frequent drinkers reported the highest number of missed medication days. About 61% of frequent drinkers reported having sex after using alcohol. Additionally, 23, 34, and 24% of nondrinkers, occasional drinkers, and frequent drinkers, respectively, reported inconsistent condom use during sex. Future intervention programs should address the issues of alcohol use and sexual risks to maximize the effectiveness of HIV treatment programs in Vietnam.

Abstract
In HIV-infected drinkers, alcohol types more likely to cause inflammation could plausibly increase the risk of HIV disease progression. We therefore assessed the association between alcohol type and plasma HIV RNA level (HIV viral load) among HIV-infected drinkers not on antiretroviral therapy (ART) in Russia and Uganda. We analyzed the data of participants from cohorts in Russia and Uganda and assessed their HIV viral load at enrollment by the alcohol type predominantly consumed. We defined predominant alcohol type as the alcohol type contributing >50% of total alcohol consumption in the 1 month (Russia) or 3 months (Uganda) prior to enrollment. Using multiple linear regression, we compared log10 HIV viral load by predominant alcohol type, controlling for age, gender, socioeconomic status, total number of standard drinks, frequency of drinking ≥6 drinks/occasion, and in Russia, history of injection drug use. Most participants (99.2% of 261 in Russia and 98.9% of 352 in Uganda) predominantly drank one alcohol type. In Russia, we did not find evidence for differences in viral load levels between drinkers of fortified wine (n = 5) or hard liquor (n = 49), compared to drinkers of beer/low-ethanol-content cocktails (n = 163); however, wine/high-ethanol-content cocktail drinkers (n = 42) had higher mean log10 viral load than beer/low-ethanol-content cocktail drinkers (β = 0.38, 95% CI 0.07-0.69; p = 0.02). In Uganda, we did not find evidence for differences in viral load levels between drinkers of locally-brewed beer (n = 41), commercially-distilled spirits (n = 38), or locally-distilled spirits (n = 43), compared to drinkers of commercially-made beer (n = 218); however, wine drinkers (n = 8) had lower mean log10 HIV viral load (β = -0.65, 95% CI -1.36 to 0.07, p = 0.08), although this did not reach statistical significance. Among HIV-infected drinkers not yet on ART in Russia and Uganda, we observed an association between the alcohol type predominantly consumed and the HIV viral load level in the Russia sample. These exploratory results suggest that, in addition to total number of drinks and drinking patterns, alcohol type might be a dimension of alcohol use that merits examination in studies of HIV and alcohol related outcomes.

Abstract
The link between HIV stigma with substance use is understudied. We characterized individuals with high HIV stigma and examined whether HIV stigma contributes to substance use among HIV-positive Russians reporting risky alcohol use. We analyzed data from HERMITAGE, a randomized controlled trial of 700 people living with HIV/AIDS (PLWHA) with past 6-month risky sex and risky alcohol use in St. Petersburg, Russia (2007-2011). Participants who were female and reported depressive symptoms and lower social support were more likely to endorse high HIV stigma (all p's < 0.001). In adjusted models, high HIV stigma was not significantly associated with the primary outcome unhealthy substance use and was not consistently associated with secondary substance use outcomes. Interventions to enhance social and mental health support for PLWHA, particularly women, may reduce stigma, though such reductions may not correspond to substantial decreases in substance use among this population.

Association between alcohol consumption and injection and sexual risk behaviors among people who inject drugs in rural Puerto Rico. J Subst Abuse Treat 2017; 82:34-40.

Abstract
Although alcohol use has been associated with risky behavior generally, the relationship between alcohol use and multiple types of risk behaviors that could lead to the acquisition and transmission of HIV and hepatitis C (HCV) among people who inject drugs (PWID) has not been fully examined. The current study seeks to contribute to the understanding of how alcohol use is related to both injection risk and sexual risk, among a non-treatment, cross-sectional sample of mostly male PWID in rural Puerto Rico (n=315). "At-risk" alcohol use was defined as consuming ≥14 drinks per week for males and ≥7 drinks per week for females. Binge drinking frequency was defined as consuming ≥5 drinks on one occasion for males and ≥4 drinks on a single occasion for females. Multivariate regression models were used to examine the association between the alcohol use variables and injection and sexual risk outcomes, adjusting for demographic characteristics. Overall, 14% (n=45) of the participants in this sample were considered at-risk drinkers (44% low risk drinkers and 42% alcohol abstainers), and participants reported binge drinking, on average, at least once per month. At-risk drinking, compared to low risk or no drinking, increased both injection and sexual risk behaviors. Frequency of past year binge drinking was also associated with both injection and sexual risk behaviors. Interventions aimed at reducing HIV and HCV transmission among injection drug users non-PWID networks should both target individuals who drink alcohol frequently and in high volumes, and include strategies for reducing risky behaviors while heavy drinking is occurring.

Abstract
BACKGROUND Alcohol use is a risk factor for nonadherence to antiretroviral therapy (ART) among people living with HIV/AIDS (PLWHA); however, differences in ART adherence across levels of alcohol use are unclear. This study examined whether "at-risk" alcohol use, defined by National Institute of Alcohol Abuse and Alcoholism guidelines, was associated with ART nonadherence among PLWHA. METHODS Participants were 535 HIV-infected adults enrolled in studies at the HIV Neurobehavioral Research Program. ART nonadherence was identified by either self-reported missed dose or plasma viral load detectability (≥50 copies/ml). Potential covariates for multivariable logistic regression included demographics, depression, and substance use disorders. RESULTS Using a stepwise model selection procedure, we found that at-risk alcohol use (OR = 0.64; p = 0.032) and low education (OR = 1.09 per 1 year increase in education; p = 0.009) significantly predict lower ART adherence. CONCLUSIONS A greater focus on the treatment of at-risk alcohol use may improve ART adherence among HIV-infected persons.

Abstract
The present study investigated the associations among alcohol use, socioeconomic status (SES), and human immunodeficiency virus (HIV) status, in the South African context. It was hypothesized that SES (predictor; measured as median split asset score) and alcohol use in the past 12 months (predictor) would interact such that current drinkers of low SES would be at an increased risk of testing HIV-positive (outcome). Nationally representative, cross-sectional survey data from 2005 (N = 16,110), 2008 (N = 13,055), and 2012 (N = 25,979) were analyzed using multinomial regression models. Current drinkers of low SES had an elevated risk of HIV infection in all survey years, ranging from a relative risk ratio (RRR) of 1.94 (95% confidence interval (CI) 1.29-3.00, t = 2.93, p = 0.002) in 2012 to RRR of 3.51 (95% CI 2.02-6.08, t = 4.47, p < 0.001) in 2008. Targeting preventive strategies to alcohol users of low SES could help reduce HIV burden and associated socioeconomic differences.

Abstract
Introduction There is limited data on the effects of alcohol on immunological response among persons living with HIV (PLHIV) in sub-Saharan Africa. We assessed the relationship between hazardous alcohol use and CD4+ T-cell count, among PLHIV in Uganda. Methods PLHIV aged ≥ 18 years were enrolled in a cohort study at the Infectious diseases clinic Kampala, Uganda. Alcohol consumption was assessed at enrolment (baseline) and 6 monthly thereafter using the alcohol use disorders identification test (AUDIT). The CD4+ T-cell counts, assessed at baseline and over the next 12 months were compared between alcohol use strata, using linear mixed effects regression. Using longitudinal mediation analysis methods, we estimated the effect of alcohol induced ART non-adherence on CD4+ T-cell count. Results Of the 1566 participants enrolled, 863(44.1%) were non-alcohol users (AUDIT score = 0), 433(27.7%) were non-hazardous (AUDIT score 1–7) alcohol users while 270 (17.2%) were hazardous (AUDIT score ≥ 8) alcohol users. The overall median (IQR) baseline CD4+ T-cell count was 356 (243–516) cells/μl. There were no differences in the median baseline CD4+ T-cell count between hazardous and non-hazardous alcohol users compared to non-alcohol users in both the non-ART (p = 0.43) and ART group (p = 0.77). The mean CD4+ T-cell count over 12 months was not different between hazardous alcohol users and non-alcohol users (non-ART group p = 0.88 and ART group p = 0.62), nor between non-hazardous alcohol users and non-alcohol users (and non-ART group p = 0.66 and ART group p = 0.20). Alcohol use was not associated with a significant natural direct effect on CD4+ T-cell count (1.37 95%CI [-1.78, 4.52] cells/μl, p = 0.39) but had a statistically significant natural indirect effect on reduction of CD4+ T-cell count (-0.91 cells/μl [-1.36, -0.45], p < 0.001) mediated through ART non-adherence. Conclusion Hazardous alcohol use among PLHIV was not directly associated with lower CD4+ T-cell count but had a significant natural indirect effect on CD4+ T-cell count mediated through ART non-adherence. Among PLHIV with lower than expected CD4+ T-cell count, alcohol consumption should be excluded as an underlying factor for non-adherence to ART and any interventions targeting alcohol use should tackle possible ART non-adherence.

Abstract
BACKGROUND Women living with HIV/AIDS who drink alcohol are at increased risk for adverse health outcomes, but there is little evidence on best methods for reducing alcohol consumption in this population. We conducted a pilot study to determine the acceptability and feasibility of conducting a larger randomized clinical trial of naltrexone vs. placebo to reduce alcohol consumption in women living with HIV/AIDS. METHODS We designed the trial with input from community and scientific review. Women with HIV who reported current hazardous drinking (>7 drinks/week or ≥4 drinks per occasion) were randomly assigned to daily oral naltrexone (50mg) or placebo for 4months. We evaluated willingness to enroll, adherence to study medication, treatment side effects, and drinking and HIV-related outcomes. RESULTS From 2010 to 2012, 17 women enrolled (mean age 49years, 94% African American). Study participation was higher among women recruited from an existing HIV cohort study compared to women recruited from an outpatient HIV clinic. Participants took 73% of their study medication; 82% completed the final assessment (7-months). Among all participants, mean alcohol consumption declined substantially from baseline to month 4 (39.2 vs. 12.8 drinks/week, p<0.01) with continued reduction maintained at 7-months. Drinking reductions were similar in both naltrexone and placebo groups. CONCLUSIONS A pharmacologic alcohol intervention was acceptable and feasible in women with HIV, with reduced alcohol consumption noted in women assigned to both treatment and placebo groups. However, several recruitment challenges were identified that should be addressed to enhance recruitment in future alcohol treatment trials.

Abstract
BACKGROUND AND AIMS Alcohol use is a major contributor to injuries, mortality and the burden of disease. This review updates knowledge on risk relations between dimensions of alcohol use and health outcomes to be used in global and national Comparative Risk Assessments (CRAs). METHODS Systematic review of reviews and meta-analyses on alcohol consumption and health outcomes attributable to alcohol use. For dimensions of exposure: volume of alcohol use, blood alcohol concentration and patterns of drinking, in particular heavy drinking occasions were studied. For liver cirrhosis, quality of alcohol was additionally considered. For all outcomes (mortality and/or morbidity): cause of death and disease/injury categories based on International Classification of Diseases (ICD) codes used in global CRAs; harm to others. RESULTS In total, 255 reviews and meta-analyses were identified. Alcohol use was found to be linked causally to many disease and injury categories, with more than 40 ICD-10 three-digit categories being fully attributable to alcohol. Most partially attributable disease categories showed monotonic relationships with volume of alcohol use: the more alcohol consumed, the higher the risk of disease or death. Exceptions were ischaemic diseases and diabetes, with curvilinear relationships, and with beneficial effects of light to moderate drinking in people without heavy irregular drinking occasions. Biological pathways suggest an impact of heavy drinking occasions on additional diseases; however, the lack of medical epidemiological studies measuring this dimension of alcohol use precluded an in-depth analysis. For injuries, except suicide, blood alcohol concentration was the most important dimension of alcohol use. Alcohol use caused marked harm to others, which has not yet been researched sufficiently. CONCLUSIONS Research since 2010 confirms the importance of alcohol use as a risk factor for disease and injuries; for some health outcomes, more than one dimension of use needs to be considered. Epidemiological studies should include measurement of heavy drinking occasions in line with biological knowledge.

Abstract
OBJECTIVE We examined the relationship between alcohol use trajectories and HIV disease severity among men and women participating in the Veterans Aging Cohort Study (VACS). DESIGN Prospective cohort of HIV-infected persons in care at eight US Veterans Health Administration sites. METHODS Between 2002 and 2010, we assessed alcohol consumption annually using the alcohol use disorders identification test-consumption (AUDIT-C). HIV disease severity was ascertained using the VACS index, a validated measure of morbidity and all-cause mortality. We examined the relationship between alcohol use and HIV disease severity patterns using joint trajectory modeling. Alcohol use trajectories were validated using phosphatidylethanol - a biomarker of alcohol consumption - measured between 2005 and 2006 among a subset of participants. We examined associations between membership in alcohol use and VACS index trajectories using multinomial regression. RESULTS Among eligible participants, we identified four alcohol consumption trajectories: abstainers (24% of the sample), lower risk (44%), moderate risk (24%), and higher risk drinkers (8%). Alcohol use trajectories were highly correlated with phosphatidylethanol (Cramér's V = 0.465, P < 0.001): mean concentrations were 4.4, 17.8, 57.7, and 167.6 ng/ml in the abstainer, lower risk, moderate risk, and higher risk groups, respectively. Four VACS index trajectories were identified: low (2%), moderate (46%), high (36%), and extreme (16%). Higher risk drinkers were most common in the extreme VACS index group, and were absent in the low index group. In multivariable analysis, the association between alcohol use and VACS index trajectory membership remained significant (P = 0.002). CONCLUSION Alcohol use trajectories characterized by persistent unhealthy drinking are associated with more advanced HIV disease severity among HIV-infected veterans in the United States.

Among patients with unhealthy alcohol use, those with HIV are less likely than those without to receive evidence-based alcohol-related care: A national VA study. Drug Alcohol Depend 2017; 174:113-120. [PMID: 28324813 PMCID: PMC5444382 DOI: 10.1016/j.drugalcdep.2017.01.018] [Citation(s) in RCA: 55] [Impact Index Per Article: 7.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2016] [Revised: 01/10/2017] [Accepted: 01/11/2017] [Indexed: 12/12/2022]
Abstract
BACKGROUND Alcohol use has important adverse effects on people living with HIV (PLWH). This study of patients with recognized unhealthy alcohol use estimated and compared rates of alcohol-related care received by PLWH and HIV- patients. METHODS Outpatients from the Veterans Health Administration who had one or more positive screen(s) for unhealthy alcohol use (AUDIT-C≥5) documented in their medical records 10/2009-5/2013 were eligible. Primary and secondary outcomes were brief intervention documented ≤14days after a positive alcohol screen, and a composite measure of any alcohol-related care (brief intervention, specialty addictions treatment or pharmacotherapy documented ≤365 days), respectively. Unadjusted and adjusted regression analyses compared alcohol-related care outcomes in PLWH and HIV- patients. RESULTS The sample included 830,825 outpatients (3,514 PLWH), reflecting 1,172,606 positive screens (1-5 per patient). For PLWH, 57.0% (95% confidence interval 55.4-58.5%) of positive screens were followed by brief intervention, compared to 73.8% (73.7-73.9%) for HIV- patients [relative rate: 0.77 (0.75-0.79), p<0.001]. After adjustment, comparable proportions were 61.0% (59.3-62.6%) for PLWH and 73.7% (73.6-73.8%) for HIV- patients [adjusted RR=0.83 (0.80-0.85); p<0.001]. Secondary outcome results were similar: for PLWH and HIV- patients, 67.1% (65.7-68.6%) and 77.7% (95% CI 77.7-77.8%) of positive screens, respectively, were followed by any alcohol-related care after adjustment [adjusted RR=0.86 (0.85-0.88), p<0.001]. CONCLUSIONS In this large national sample of VA outpatients with unhealthy alcohol use, PLWH were less likely to receive alcohol-related care than HIV- patients. Special efforts may be needed to ensure alcohol-related care reaches PLWH.

Abstract
In the first part of this review, the nature of the associations between alcohol use and HIV/AIDS is discussed. Alcohol use has been found to be strongly associated with incidence and progression of HIV/AIDS, but the extent to which this association is causal has traditionally remained in question. Experiments where alcohol use has been manipulated as the independent variable have since helped establish a causal effect of alcohol use on the intention to engage in condomless sex. As the intention to engage in condomless sex is a surrogate measure of actual condom use behavior, which itself is linked to HIV incidence and re-infection, the causal chain has been corroborated. Moreover, there are biological pathways between alcohol use and the course of HIV/AIDS, only in part being mediated by adherence to antiretroviral medication. In the second part of the contribution, we provide suggestions on the quantification of the link between alcohol use and HIV incidence, using risk relations derived from experimental data. The biological links between alcohol use and course of HIV/AIDS are difficult to quantify given the current state of knowledge, except for an operationalization for the link via adherence to medication based on meta-analyses. The suggested quantifications are exemplified for South Africa.

Abstract
BACKGROUND Emerging research points to innate immune mechanisms in the neuropathological and behavioral consequences of heavy alcohol use. Alcohol use is common among people living with HIV infection (PLWH), a chronic condition that carries its own set of long-term effects on brain and behavior. Notably, neurobiological and cognitive profiles associated with heavy alcohol use and HIV infection share several prominent features. This observation raises questions about interacting biological mechanisms as well as compounded impairment when HIV infection and heavy drinking co-occur. OBJECTIVE AND METHOD This narrative overview discusses peer-reviewed research on specific immune mechanisms of alcohol that exhibit apparent potential to compound the neurobiological and psychiatric sequelae of HIV infection. These include microbial translocation, systemic immune activation, blood-brain barrier compromise, microglial activation, and neuroinflammation. RESULTS Clinical and preclinical evidence supports overlapping mechanistic actions of HIV and alcohol use on peripheral and neural immune systems. In preclinical studies, innate immune signaling mediates many of the detrimental neurocognitive and behavioral effects of alcohol use. Neuropsychopharmacological research suggests potential for a feed-forward cycle in which heavy drinking induces innate immune signaling, which in turn stimulates subsequent alcohol use behavior. CONCLUSION Alcohol-induced immune activation and neuroinflammation are a serious health concern for PLWH. Future research to investigate specific immune effects of alcohol in the context of HIV infection has potential to identify novel targets for therapeutic intervention.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) is stigmatized and disproportionately impacts vulnerable populations. Thus, people living with HIV (PLWH) may have greater exposure to psychosocial stressors than those without HIV. Exposure to psychosocial stressors may increase alcohol use and serve as barriers to alcohol treatment receipt. The authors evaluate whether psychosocial stressors and alcohol use, symptom severity, and treatment receipt vary across HIV status in a general population sample of US residents and assess whether psychosocial stressors mediate identified associations. METHODS Data from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were used to assess associations between HIV status and psychosocial stressors (perceived stress, alcohol-related stigma, and perceived discrimination based on race/ethnicity, sexual orientation, or sex) and alcohol-related outcomes (any use, heavy drinking, symptom severity, and treatment receipt). For each outcome, regression models were fit and iteratively adjusted for sociodemographic characteristics and comorbidities. Indirect effects of HIV on alcohol-related outcomes through stressors were estimated to assess mediation when main effects were significant. RESULTS Among 34,653 NESARC Wave 2 respondents, 161 were PLWH. PLWH were more likely than those without HIV to experience discrimination and had higher levels of perceived stress than those without HIV (P values <.05), but the 2 groups did not differ regarding alcohol-related stigma. PLWH were less likely to use alcohol and had similar rates of heavy drinking relative to participants without HIV, but alcohol symptom severity and treatment receipt were greater among PLWH. Perceived stress but not discrimination mediated associations. CONCLUSIONS Findings from this first study of variation in psychosocial stressors and alcohol use, severity, and treatment receipt across HIV status further highlight PLWH as a population that is particularly vulnerable to experiences of psychosocial stress and certain adverse alcohol-related outcomes. Future longitudinal research is needed in a larger sample of PLWH to identify intervention targets.

Abstract
INTRODUCTION Heavy drinking can be harmful for individuals with HIV, particularly those coinfected with hepatitis C virus (HCV). HIV patients' reasons for drinking predict short-term alcohol involvement, but whether they predict longer-term involvement is unknown. Also, it remains unknown whether these motives are differentially predictive for HIV monoinfected and HIV/HCV coinfected patients. METHOD HIV-infected heavy drinkers (n = 254) participated in a randomized trial of brief alcohol interventions, 236 (92.9%) of whom reported on baseline motives and alcohol involvement 12 months later (77.1% male, 94.9% minority, 30.6% with HCV). RESULTS Greater endorsement of baseline drinking to cope with negative affect predicted greater alcohol dependence symptoms at 12 months (incident rate ratio [IRR] = 1.80, p < 0.05), while greater endorsement of baseline drinking due to social pressure predicted fewer drinks consumed at 12 months (IRR = 0.67, p < 0.05). Coping and social reasons were both predictive for HIV monoinfected patients, whereas only coping reasons were predictive for HIV/HCV coinfected patients. DISCUSSION Drinking for coping and social reasons predict alcohol involvement 12 months later; however, social reasons may only be important for HIV monoinfected patients. Understanding patient reasons for drinking may help predict patient risk up to a year later. KEY MESSAGES Among HIV patients, drinking motives predict alcohol involvement 12 months later. For HIV monoinfected patients, drinking to cope and drinking for social reasons predict 12-month alcohol involvement. For HIV/Hepatitis C coinfected patients, coping (but not social) motives predict 12-month alcohol involvement.

Contemp Clin Trials 2016; 52:80-90.

Abstract
Unhealthy alcohol use is common among HIV-positive patients, yet effective evidence-based treatments are rarely provided in clinical settings providing HIV care. Further, given patient variability in response to initial treatments, stepped care approaches may be beneficial. We describe the rationale, aims and study design for the current StartingTreatment forEthanol inPrimary care Trials (STEP Trials); three parallel randomized controlled effectiveness trials being conducted in five Infectious Disease Clinics. Participants meeting criteria for: 1) at-risk drinking, 2) moderate alcohol use with liver disease (MALD), or 3) alcohol use disorder (AUD) are randomized to integrated stepped care versus treatment as usual. For those with at-risk drinking or MALD, integrated stepped care starts with a one session brief intervention and follow-up 2-week telephone booster. Based on pre-specified nonresponse criteria, participants may be "stepped up" at week 4 to receive four sessions of motivational enhancement therapy (MET) and "stepped up" again at week 12 for addiction physician management (APM) and consideration of alcohol pharmacotherapy. For those with AUD, integrated stepped care begins with APM. Non-responders may be "stepped up" at week 4 to receive MET and again at week 12 for a higher level of care (e.g. intensive outpatient program). The primary outcome is alcohol consumption assessed at 24weeks, and secondary outcome is the VACS Index, a validated measure of HIV morbidity and mortality risk. Results from the STEP Trials should inform future research and the implementation of interventions to address unhealthy alcohol use among HIV-positive individuals.

Abstract
OBJECTIVES HIV-infected adults have heightened monocyte activation and inflammation, at least partially as a consequence of altered gut integrity. The role of dietary factors in microbial translocation and inflammation and their downstream effect on markers of cardiovascular disease (CVD) have not been explored. Our purpose was to describe the longitudinal dietary patterns of HIV-infected adults, and to examine the relationship between dietary intake, gut integrity, inflammation and subclinical markers of CVD in HIV-infected adults. METHODS We conducted a secondary analysis of 147 HIV-infected participants in a 96-week randomized clinical trial of rosuvastatin as primary CVD prevention. Dietary intake was assessed using dietary recall; plasma gut integrity, monocyte activation and inflammation markers were measured using an enzyme-linked immunosorbent assay (ELISA); and CVD risk was assessed using carotid ultrasound and the coronary artery calcium score. Linear mixed models were used to analyse longitudinally measured biomarkers. RESULTS The median age was 45 years and 78% of patients were male. At baseline, participants consumed a mean (standard deviation) of 108 (70) g of fat daily, 19 (15.6) g of fibre, 266 (186) g of carbohydrates and 15.6 (5.9) g of protein; 45% of the sample consumed alcohol. Over time, alcohol consumption was associated with several markers of gut integrity and inflammation (all P < 0.05). CONCLUSIONS HIV-infected adults in a contemporary, high-resource setting have poor dietary patterns. Alcohol use was associated with worse gut integrity and increased inflammation, while other aspects of diet (fibre, carbohydrates and fat) were not. These data add to growing evidence illustrating the need for a better understanding of the effect of lifestyle factors on comorbidities in HIV-infected adults.

Abstract
Alcohol use disorder (AUD) and hepatitis C virus (HCV) infection frequently co-occur. AUD is associated with greater exposure to HCV infection, increased HCV infection persistence, and more extensive liver damage due to interactions between AUD and HCV on immune responses, cytotoxicity, and oxidative stress. Although AUD and HCV infection are associated with increased morbidity and mortality, HCV antiviral therapy is less commonly prescribed in individuals with both conditions. AUD is also common in human immunodeficiency virus (HIV) infection, which negatively impacts proper HIV care and adherence to antiretroviral therapy, and liver disease. In addition, AUD and HCV infection are also frequent within a proportion of patients with HIV infection, which negatively impacts liver disease. This review summarizes the current knowledge regarding pathological interactions of AUD with hepatitis C infection, HIV infection, and HCV/HIV co-infection, as well as relating to AUD treatment interventions in these individuals.

Abstract
Independently, HIV infection and heavy alcohol use increase microbial translocation (MT) of gut products into systemic circulation. MT and consequent immune response have been linked to chronic inflammation and a host of negative health outcomes in individuals living with HIV. However, previous research has not systematically investigated the immune correlates of heavy drinking specifically within the HIV-positive population. This pilot study investigated MT and immune activation as a function of alcohol use in 21 HIV-positive men who met NIAAA criteria for heavy drinking. Participants averaged 46.7 ± 8.5 (mean ± standard deviation) years of age, 12.2 ± 9.2 years since HIV diagnosis, 337 ± 158 CD4 nadir, and 643 ± 245 current CD4 count. All participants were virologically suppressed on antiretroviral therapy. Data on alcohol use and immune function were collected at baseline and three-month follow-up. Plasma concentrations of markers of MT and immune activation (lipopolysaccharide (LPS), soluble CD14 (sCD14), endotoxin core antibody immunoglobulin M (EndoCAb)) were measured using enzyme-linked immunosorbent assays. Generalized estimating equation models tested alcohol use variables as predictors of LPS, sCD14, and EndoCAb levels. Greater quantity and frequency of drinking significantly predicted higher sCD14 levels (p's < .01). Conversely, longer duration of abstinence from alcohol significantly predicted lower sCD14 levels (p < .001). These results remained significant after controlling for age, HIV duration, smoking status, current CD4 count, CD4 nadir, and antiretroviral drug type. In addition, participants with ≥50% relative reduction in drinks per week showed a significant decrease (p < .05) in sCD14 from baseline to three-month follow-up. This pilot study provides preliminary evidence that heavy drinking may increase a key inflammatory marker in HIV-infected individuals with suppressed infection.

Abstract
BACKGROUND Using electronic medical record (EMR) data for clinical decisions, quality improvement, and research is common. While unhealthy alcohol use is particularly risky among HIV infected individuals (HIV+), the validity of EMR data for identifying unhealthy alcohol use among HIV+ is unclear. Among HIV+ and uninfected, we: (1) assess agreement of EMR and research AUDIT-C at validated cutoffs for unhealthy alcohol use; (2) explore EMR cutoffs that maximize agreement; and (3) assess subpopulation variation in agreement. METHODS Using data from the Veterans Aging Cohort Study (VACS), EMR AUDIT-C cutoffs of 2+, 3+, and 4+ for men (2+ and 3+ for women) were compared to research AUDIT-C 4+ for men (3+ for women). Agreement was compared by demographics, HIV, hepatitis C infection, and alcohol related diagnosis. RESULTS Among 1082 HIV+ and 1160 uninfected men, 14% and 22% had an EMR and research AUDIT-C 4+, respectively. Among 32 HIV+ and 115 uninfected women, 9% and 14% had an EMR and research AUDIT-C 3+. For men, EMR agreement with the research AUDIT-C 4+ was highest at a cutoff of 3+ (kappa=0.49). For women, EMR agreement with AUDIT-C 3+ was highest at a cutoff of 2+ (kappa=0.46). Moderate agreement was consistent across subgroups. CONCLUSIONS EMR AUDIT-C underestimates unhealthy alcohol use compared to research AUDIT-C in both HIV+ and uninfected individuals. Methods for improving quality of clinical screening may be in need of investigation. Researchers and clinicians may consider alternative EMR cutoffs that maximize agreement given limitations of clinical screening.

Abstract
Alcohol use is common among people living with human immunodeficiency virus (HIV). In this narrative review, we describe literature regarding alcohol's impact on transmission, care, coinfections, and comorbidities that are common among people living with HIV (PLWH), as well as literature regarding interventions to address alcohol use and its influences among PLWH. This narrative review identifies alcohol use as a risk factor for HIV transmission, as well as a factor impacting the clinical manifestations and management of HIV. Alcohol use appears to have additive and potentially synergistic effects on common HIV-related comorbidities. We find that interventions to modify drinking and improve HIV-related risks and outcomes have had limited success to date, and we recommend research in several areas. Consistent with Office of AIDS Research/National Institutes of Health priorities, we suggest research to better understand how and at what levels alcohol influences comorbid conditions among PLWH, to elucidate the mechanisms by which alcohol use is impacting comorbidities, and to understand whether decreases in alcohol use improve HIV-relevant outcomes. This should include studies regarding whether state-of-the-art medications used to treat common coinfections are safe for PLWH who drink alcohol. We recommend that future research among PLWH include validated self-report measures of alcohol use and/or biological measurements, ideally both. Additionally, subgroup variation in associations should be identified to ensure that the risks of particularly vulnerable populations are understood. This body of research should serve as a foundation for a next generation of intervention studies to address alcohol use from transmission to treatment of HIV. Intervention studies should inform implementation efforts to improve provision of alcohol-related interventions and treatments for PLWH in healthcare settings. By making further progress on understanding how alcohol use affects PLWH in the era of HIV as a chronic condition, this research should inform how we can mitigate transmission, achieve viral suppression, and avoid exacerbating common comorbidities of HIV and alcohol use and make progress toward the 90-90-90 goals for engagement in the HIV treatment cascade.

Abstract
Heavy drinking among HIV-infected individuals is associated with health complications. Health-behavior self-efficacy may be characteristically low among this population or negatively affected by HIV-infected status. We assessed whether self-efficacy to resist drinking increased during brief educational and motivational drinking-reduction interventions within HIV primary care and whether increases in self-efficacy predicted drinking among HIV-infected heavy drinkers. Results indicate that increases in self-efficacy from baseline to end-of-intervention inversely predicted drinking at end-of-intervention and at follow-up. Findings suggest that brief treatment interventions within HIV primary care may promote self-efficacy and that increases in self-efficacy predict initiation and maintenance of drinking reductions among HIV patients.

Abstract
BACKGROUND The role of alcohol consumption in HIV-related adaptive immune dysfunction is debated. We hypothesized that heavy drinking would be associated with greater evidence of immunosenescence (i.e., aging-related decline of adaptive immune function) among antiretroviral therapy (ART)-naïve HIV-infected individuals. METHODS Using data from the Russia ARCH cohort study, we conducted a cross-sectional analysis of ART-naïve HIV-infected individuals recruited between 2012 and 2014. INDEPENDENT VARIABLE Heavy drinking defined as >4 standard drinks in a day (or >14 standard drinks per week) for men and >3 per day (or >7 per week) for women, respectively. DEPENDENT VARIABLES Percentage of CD8+ and CD4+ T-cells with a phenotype consistent with immunosenescence (i.e., expressing CD28- CD57+, or memory [CD45RO+ CD45RA+] phenotype and not the naïve [CD45RO- CD45RA+] phenotype). STATISTICAL ANALYSIS Multiple linear regression adjusted for confounders. RESULTS Of 214 eligible participants, 61% were heavy drinkers. Mean age was 33 years and the cohort was predominantly male (72%). Hepatitis C prevalence was high (87%) and mean log10 HIV-1 RNA copies/ml was 4.6. We found no significant differences by drinking status in the percentage of immunosenescent, memory, or naïve CD8+ or CD4+ T-cells. CONCLUSIONS In this cross-sectional analysis, heavy drinking in the setting of untreated HIV infection did not appear to be associated with alterations in T-cell phenotypes consistent with immunosenescence. To substantiate these findings, longitudinal studies should assess whether changes in alcohol consumption are associated with changes in these and other immunosenescent T-cell phenotypes.

Abstract
Female sex workers (FSW) have a high prevalence of substance use and HIV, but the impact of substance use on HIV treatment engagement is not well established. We evaluated the association between alcohol and marijuana use and sub-optimal HIV treatment engagement outcomes among HIV-infected FSW in Lilongwe, Malawi. We enroled FSW using venue-based recruitment into a cross-sectional evaluation assessing substance use and HIV treatment engagement. Seropositive FSW, identified through HIV rapid testing, received rapid CD4 count and viral load testing. We used Poisson regression with robust variance estimates to ascertain associations of alcohol and marijuana use with sub-optimal HIV treatment outcomes: (1) lack of ART use among previously diagnosed, ART-eligible FSW and (2) viral nonsuppression among FSW on ART. Of previously diagnosed, ART-eligible FSW (n = 96), 29% were not using ART. Patterns of hazardous drinking were identified in 30%, harmful drinking in 10%, and alcohol dependence in 12%. ART-eligible FSW with harmful drinking or alcohol dependency were 1.9 (95% CI: 1.0, 3.8) times as likely to not use ART compared to FSW without harmful or dependent drinking. Among those on ART, 14% were virally nonsuppressed. The prevalence ratio for viral nonsuppression was 2.0 (95% CI: 0.6, 6.5) for harmful drinkers and alcohol-dependent FSW. Over 30% of ART-eligible FSW reported using marijuana. Marijuana-using FSW were 1.9 (95% CI: 0.8, 4.6) times as likely to not use ART compared to FSW who were not using marijuana. Given the high prevalence of alcohol use and its association with lack of ART use, ART uptake and alcohol reduction strategies should be tailored for alcohol-using FSW in Malawi.

Abstract
BACKGROUND Alcohol consumption is highly prevalent in the general population and among HIV-infected population. This study aimed to compare the pattern of alcohol consumption and to describe characteristics associated with heavy alcohol consumption in individuals from the general population with patients infected with HIV. METHODS Participants for this analysis came from a population-based cross-sectional study and from a consecutive sampling of patients infected with HIV. Participants aged 18 years or older were interviewed using similar questionnaires with questions pertaining to socio-demographic characteristics, alcohol consumption, smoking, physical activity, and HIV-related characteristics, among others. Blood pressure and anthropometric measures were measured using standardized procedures. RESULTS Weekly alcohol consumption was more prevalent among individuals from the general population than HIV-infected patients: 57.0 vs. 31.1%, P<0.001. The prevalence of heavy episodic drinking was higher in the population sample as well: 46.1 vs. 17.0%, P<0.001. In the general population, heavy alcohol consumption was more prevalent in men. Cigarette smoking was independently associated with heavy alcohol consumption among HIV infected (Prevalence Ratio; PR = 5.9; 95%CI 2.6-13.9; P<0,001) and general population (PR = 2.6; 95%CI 1.9-3.0; P<0.001). Years at school were inversely associated with heavy alcohol consumption among HIV-infected patients and directly associated among participants from the general population, even after controlling for sex, age, skin color, and smoking. CONCLUSIONS Heavy alcohol consumption is more prevalent in the general population than among HIV-infected patients. Individuals aware about their disease may reduce the amount of alcoholic beverages consumption comparatively to healthy individuals from the general population.

Abstract
BACKGROUND Certain anti-HIV drugs alone or in combination are often associated with liver damages, which are frequently worsened by alcohol consumption. We previously found an endoplasmic reticulum (ER) stress mechanism for the drug- and alcohol-induced hepatic injuries in animal models and in vitro hepatocytes. However, it is unknown whether anti-HIV drugs and alcohol induce similar cellular stress responses and injuries in liver nonparenchymal cells. METHODS Primary mouse hepatocytes (PMH), kupffer cells (KC), and hepatocellular stellate cells (HSC) were freshly isolated from mouse liver and treated with DMSO, stress-inducing pharmaceutical agents, alcohol alone, or in combination with antiviral ritonavir (RIT), lopinavir (LOP), or efavirenz (EFV). Expression of cellular stress markers, protein colocalization, and cell death were analyzed with immunoblotting, immunocytochemistry, and positive double staining with Sytox green and Hoechst blue, respectively. RESULTS Expression of the ER stress markers of BiP, CHOP, and SERCA and the autophagy marker LC3 was significantly changed in PMH in response to combined alcohol, RIT, and LOP, which was companied by increased cell death compared with control. In contrast, although pharmaceutical agents induced ER stress and cell death, no significant ER stress or cell death was found in KC treated with alcohol, RIT, LOP, and EFV singly or in combination. In HSC, alcohol, RIT, LOP, or EFV induced BiP, but not CHOP, SERCA, or cell death compared with vehicle control. Further in PMH, RIT and LOP or in combination with alcohol-induced dose-dependent inhibition of β-actin. Inhibition of β-actin by RIT and LOP was companied with an inhibited nuclear expression of the antioxidant response regulator Nrf2 and reduced GST downstream of Nrf2. Ascorbic acid treatment reduced the alcohol-, RIT-, and LOP-induced cell death. CONCLUSIONS The data suggest for the first time that sensitivities of hepatocytes and nonparenchymal cells to alcohol and anti-HIV drugs in vitro are different in terms of cellular stress response and cell death injury. Oxidative stress mediated by Nrf2 contributes to the alcohol- and drug-induced toxicity in the hepatocytes.
