RESUMEN
BACKGROUND: In South Africa, an estimated 11% of the population have high alcohol use, a major risk factor for TB. Alcohol and other substance use are also associated with poor treatment response, with a potential mechanism being altered TB drug pharmacokinetics. OBJECTIVES: To investigate the impact of alcohol and illicit substance use on the pharmacokinetics of first-line TB drugs in participants with pulmonary TB. METHODS: We prospectively enrolled participants ≥15 years old, without HIV, and initiating drug-susceptible TB treatment in Worcester, South Africa. Alcohol use was measured via self-report and blood biomarkers. Other illicit substances were captured through a urine drug test. Plasma samples were drawn 1 month into treatment pre-dose, and 1.5, 3, 5 and 8 h post-dose. Non-linear mixed-effects modelling was used to describe the pharmacokinetics of rifampicin, isoniazid, pyrazinamide and ethambutol. Alcohol and drug use were tested as covariates. RESULTS: The study included 104 participants, of whom 70% were male, with a median age of 37 years (IQR 27-48). Alcohol use was high, with 42% and 28% of participants having moderate and high alcohol use, respectively. Rifampicin and isoniazid had slightly lower pharmacokinetics compared with previous reports, whereas pyrazinamide and ethambutol were consistent. No significant alcohol use effect was detected, other than 13% higher ethambutol clearance in participants with high alcohol use. Methaqualone use reduced rifampicin bioavailability by 19%. CONCLUSION: No clinically relevant effect of alcohol use was observed on the pharmacokinetics of first-line TB drugs, suggesting that poor treatment outcome is unlikely due to pharmacokinetic alterations. That methaqualone reduced rifampicin means dose adjustment may be beneficial.

Although alcohol use is associated with depression, it is unclear if brief alcohol reduction interventions can ameliorate depression and psychological distress among people with HIV (PWH). We use data from a two-arm randomised controlled trial to examine this question. PWH on antiretroviral treatment (ART) were randomly assigned to receive a brief intervention or treatment as usual (n = 622). Screening was done with the Alcohol Use Disorders Identification Test (AUDIT), AUDIT-C, Centre for Epidemiological Studies Depression inventory and Kessler Psychological Distress Scale, at baseline and at 3- and 6-months post-baseline. Changes in depression and psychological distress was assessed using analysis of covariance models with baseline measures of alcohol consumption, sex and age included as covariates and adjusting for baseline symptom severity. Changes in alcohol consumption between baseline and follow-up were included in the analysis to establish if this affected outcomes. For both the intervention and control groups, there were significant reductions in symptom severity at 3-months and 6-months for depression and psychological distress, but no significant between group differences were observed. Reductions in alcohol consumption were significantly associated with reductions in depression and psychological distress, supporting the hypothesis that alcohol use is linked to depression among PWH.Trial Registration Pan African Clinical Trials Register, PACTR201405000815100.nh.

Alcohol use disorders (AUD) among people living with HIV (PLHIV) are associated with poor health outcomes. This cross-sectional study examined current alcohol use and AUD among 300 PLHIV on ART at four HIV care centres in Northwest Tanzania. Participants' data were collected using questionnaires. Alcohol use was assessed using Alcohol Use Disorders Identification Test (AUDIT). Logistic regression was used to examine associations between each outcome (current drinking and AUD) and sociodemographic and clinical factors. Association between alcohol use and ART adherence was also studied. The median age of participants was 43 years (IQR 19-71) and 41.3% were male. Twenty-two (7.3%) participants failed to take ART at least once in the last seven days. The prevalence of current drinking was 29.3% (95% CI 24.2-34.8%) and that of AUD was 11.3% (8.2%-15.5%). Males had higher odds of alcohol use (OR 3.03, 95% CI 1.79-5.14) and AUD (3.89, 1.76-8.60). Alcohol use was associated with ART non-adherence (OR = 2.78, 1.10-7.04). There was a trend towards an association between AUD and non-adherence (OR = 2.91, 0.92-9.21). Alcohol use and AUD were common among PLHIV and showed evidence of associations with ART non-adherence. Screening patients for alcohol use and AUD in HIV clinics may increase ART adherence.

BACKGROUND: This study is the ninth cross-sectional community study of fetal alcohol spectrum disorders (FASD) conducted by the multidisciplinary Fetal Alcohol Syndrome Epidemiology Research team in the Western Cape Province of South Africa. It is the third comprehensive study of FASD in a rural, agricultural region of South Africa. METHODS: Population-based, active case ascertainment methods were employed among a school-based cohort to assess child physical and neurobehavioral traits, and maternal risk factor interviews were conducted to identify all children with FASD to determine its prevalence. RESULTS: Consent was obtained for 76.7% of 1158 children attending first grade in the region's public schools. Case-control results are presented for 95 with fetal alcohol syndrome (FAS), 64 with partial fetal alcohol syndrome (PFAS), 77 with alcohol-related neurodevelopmental disorder (ARND), 2 with alcohol-related birth defects (ARBD), and 213 randomly-selected controls. Four techniques estimating FASD prevalence from in-person examinations and testing yielded a range of total FASD prevalence of 206-366 per 1000. The final weighted, estimated prevalence of FAS was 104.5 per 1000, PFAS was 77.7 per 1000, ARND was 125.2 per 1000, and total FASD prevalence was 310 per 1000 (95% CI = 283.4-336.7). Expressed as a percentage, 31% had FASD. Although the rate of total FASD remained steady over 9 years, the proportion of children within the FASD group has changed significantly: FAS trended down and ARND trended up. A detailed evaluation is presented of the specific child physical and neurobehavioral traits integral to assessing the full continuum of FASD. The diagnosis of a child with FASD was significantly associated with maternal proximal risk factors such as: co-morbid prenatal use of alcohol and tobacco (OR = 19.1); maternal drinking of two (OR = 5.9), three (OR = 5.9), four (OR = 38.3), or more alcoholic drinks per drinking day; and drinking in the first trimester (OR = 8.4), first and second trimesters (OR = 17.7), or throughout pregnancy (OR = 18.6). Distal maternal risk factors included the following: slight or small physical status (height, weight, and head circumference), lower BMI, less formal education, late recognition of pregnancy, and higher gravidity, parity, and older age during the index pregnancy. CONCLUSION: The prevalence of FASD remained a significant problem in this region, but the severity of physical traits and anomalies within the continuum of FASD is trending downwards.

OBJECTIVE: To investigate gestational age and growth at birth as predictors of fetal alcohol spectrum disorders (FASD). METHODS: The sample analyzed here comprises 737 randomly selected children who were assessed for growth, dysmorphology, and neurobehavior at 7 years of age. Maternal interviews were conducted to ascertain prenatal alcohol exposure and other maternal risk factors. Birth data originated from clinic records and the data at 7 years of age originated from population-based, in-school studies. Binary linear regression assessed the relationship between preterm birth, small for gestational age (SGA), and their combination on the odds of a specific FASD diagnosis or any FASD. RESULTS: Among children diagnosed with FASD at 7 years of age (n = 255), a review of birth records indicated that 18.4% were born preterm, 51.4% were SGA, and 5.9% were both preterm and SGA. When compared to non-FASD controls (n = 482), the birth percentages born preterm, SGA, and both preterm and SGA were respectively 12.0%, 27.7%, and 0.5%. Mothers of children with FASD reported more drinking during all trimesters, higher gravidity, lower educational attainment, and older age at pregnancy. After controlling for usual drinks per drinking day in the first trimester, number of trimesters of drinking, maternal education, tobacco use, and maternal age, the odds ratio of an FASD diagnosis by age 7 was significantly associated with SGA (OR = 2.16, 95% CI: 1.35 to 3.45). SGA was also significantly associated with each of the 3 most common specific diagnoses within the FASD continuum: fetal alcohol syndrome (FAS; OR = 3.1), partial FAS (OR = 2.1), and alcohol-related neurodevelopmental disorder (OR = 2.0). CONCLUSION: SGA is a robust early indicator for FASD in this random sample of children assessed at 7 years of age.

Substance use is a recognized risk factor for HIV acquisition, transmission and progression in South Africa. Persons who use drugs (PWUD) and access specialist substance abuse treatment centers (SSATCs) are a potentially critical target group for HIV services because of the severity of their substance use and associated health risks. SSATCs represent an opportunity for integrated programming, particularly HIV testing services (HTS), to reach PWUD who are at an increased risk of or living with HIV. This analysis of national SSATC admission data explores self-reported HIV testing and associated factors to identify coverage gaps and integration opportunities. The South African Community Epidemiology Network on Drug Use (SACENDU) collects routine surveillance data to monitor national treatment admission trends in alcohol and other drug use. SACENDU data from 2012 to 2017 was analyzed using chi-square test of independence and logistic regression to examine associations between HTS, demographic characteristics and substances of use. Of 87,339 treatment admissions, 47.5% (n = 41,481) of patients had not accessed HTS in the prior 12 months. HTS was reported less frequently by patients whose primary substance of use was cannabis or those with polysubstance use (36.9% and 41.1%, respectively). None of the substance use sub-groups reported a testing rate above 70%. Compared to specific reference groups, logistic regression showed those with lower odds of HTS were: 15-19 years (OR = 0.59); had primary-level education (OR = 0.51); were scholars/learners (OR = 0.27); and primarily cannabis users (OR = 0.64). Patients whose primary drug was heroin had higher odds of testing (OR = 2.45) as did those who injected drugs (OR = 2.86). Given the low coverage and decreased odds of self-reported HTS among sub-groups of patients in SSATCs, the integration of HIV services for PWUD should be a priority in South Africa and a focus of the national HIV strategy.

BACKGROUND: Sexual reproductive health communication between parents and children has been shown to promote safer sexual choices. In many South African households, third-generation female caregivers, often grandmothers or other older females, locally known as gogos, are primary caregivers of children due to parents being deceased or absent. Subsequently, the responsibility of talking about sex and related issues has shifted to these gogos. This study explored the experiences of gogos living in Alexandra, Johannesburg on talking about sex, sexuality and HIV and AIDS with children aged 10-18 years that are in their care. METHODS: Ten primary caregivers were purposively selected. Data were collected through in-depth individual interviews. Thematic analysis was performed and inductive codes and themes identified. RESULTS: All gogos selected found it difficult to discuss sex, sexuality and HIV and AIDS due to culture and traditional values impacting on personal experiences as well as generation and gender barriers. Perceived low self-efficacy due to low levels of knowledge and limited skills in speaking about sex, sexuality and HIV and AIDS also contributed to low levels of sexual reproductive health communication. CONCLUSIONS: This study highlights the need for interventions that focus on improving gogos' knowledge about sexual reproductive health in addition to providing them with the skills to talk about sex, sexuality and HIV and AIDS with children in their care.

BACKGROUND: Medical treatment and detoxification from opiate disorders includes oral administration of opioid agonists. Dihydrocodeine (DHC) substitution treatment is typically low threshold and therefore has the capacity to reach wider groups of opiate users. Decisions to prescribe DHC to patients with less severe opiate disorders centre on its perceived safety, reduced toxicity, shorter half-life and more rapid onset of action, and potential retention of patients. This review set out to investigate the effects of DHC in comparison to other pharmaceutical opioids and placebos in the detoxification and substitution of individuals with opiate use disorders. OBJECTIVES: To investigate the effectiveness of DHC in reducing illicit opiate use and other health-related outcomes among adults compared to other drugs or placebos used for detoxification or substitution therapy. SEARCH METHODS: In February 2019 we searched Cochrane Drugs and Alcohol's Specialised Register, CENTRAL, PubMed, Embase and Web of Science. We also searched for ongoing and unpublished studies via ClinicalTrials.gov, the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) and Trialsjournal.com. All searches included non-English language literature. We handsearched references of topic-related systematic reviews and the included studies. SELECTION CRITERIA: We included randomised controlled trials that evaluated the effect of DHC for detoxification and maintenance substitution therapy for adolescent (aged 15 years and older) and adult illicit opiate users. The primary outcomes were abstinence from illicit opiate use following detoxification or maintenance therapy measured by self-report or urinalysis. The secondary outcomes were treatment retention and other health and behaviour outcomes. DATA COLLECTION AND ANALYSIS: We followed the standard methodological procedures that are outlined by Cochrane. This includes the GRADE approach to appraise the quality of evidence. MAIN RESULTS: We included three trials (in five articles) with 385 opiate-using participants that measured outcomes at different follow-up periods in this review. Two studies with 150 individuals compared DHC with buprenorphine for detoxification, and one study with 235 participants compared DHC to methadone for maintenance substitution therapy. We downgraded the quality of evidence mainly due to risk of bias and imprecision. For the two studies that compared DHC to buprenorphine, we found low-quality evidence of no significant difference between DHC and buprenorphine for detoxification at six-month follow-up (risk ratio (RR) 0.59, 95% confidence interval (CI) 0.25 to 1.39; P = 0.23) in the meta-analysis for the primary outcome of abstinence from illicit opiates. Similarly, low-quality evidence indicated no difference for treatment retention (RR 1.29, 95% CI 0.99 to 1.68; P = 0.06). In the single trial that compared DHC to methadone for maintenance substitution therapy, the evidence was also of low quality, and there may be no difference in effects between DHC and methadone for reported abstinence from illicit opiates (mean difference (MD) -0.01, 95% CI -0.31 to 0.29). For treatment retention at six months' follow-up in this single trial, the RR calculated with an intention-to-treat analysis also indicated that there may be no difference between DHC and methadone (RR 1.04, 95% CI 0.94 to 1.16). The studies that compared DHC to buprenorphine reported no serious adverse events, while the DHC versus methadone study reported one death due to methadone overdose. AUTHORS' CONCLUSIONS: We found low-quality evidence that DHC may be no more effective than other commonly used pharmacological interventions in reducing illicit opiate use. It is therefore premature to make any conclusive statements about the effectiveness of DHC, and it is suggested that further high-quality studies are conducted, especially in low- to middle-income countries.

The prevalence and risk factors associated with peripartum psychological distress-a unifying factor among common mental disorders (CMDs)-are not widely understood in underresourced settings. Cross-sectional data were collected from 664 pregnant women who reported for antenatal care at any of one of the 11 midwife and obstetrics units in Cape Town, South Africa. The prevalence of prepartum psychological distress was 38.6%. Associated factors included low socioeconomic status as measured by asset ownership (odds ratio [OR], 1.45; 95% CI, 1.24-1.68), recent physical abuse and/or rape (OR, 1.94; 95% CI, 1.57-2.40), complications during a previous birth (OR, 1.18; 95% CI, 1.01-1.38), and having given birth before (OR, 1.61; 95% CI, 1.21-2.14). The high prevalence of psychological distress is consistent with those found in other South African studies of peripartum CMDs. If effective context-specific interventions are to be appropriately designed, closer investigation of a broader symptomology associated with peripartum CMDs in these settings is warranted.

Fascin is an actin binding and bundling protein that is not expressed in normal epithelial tissues but overexpressed in a variety of invasive epithelial tumors. It has a critical role in cancer cell metastasis by promoting cell migration and invasion. Here we report the crystal structures of fascin in complex with a series of novel and potent inhibitors. Structure-based elaboration of these compounds enabled the development of a series with nanomolar affinities for fascin, good physicochemical properties and the ability to inhibit fascin-mediated bundling of filamentous actin. These compounds provide promising starting points for fascin-targeted anti-metastatic therapies.

BACKGROUND: People living with HIV (PLWH) who drink alcohol and use tobacco are particularly vulnerable to tobacco-induced diseases due to an already compromised immune system. This study investigated the prevalence and factors associated with tobacco use (cigarette and snuff) among PLWH who drink heavily. METHODS: Participants (n = 623) on antiretroviral therapy for HIV who reported heavy drinking using the Alcohol Use Disorders Identification Test (AUDIT) and AUDIT-C were recruited from six hospitals in Gauteng Province, South Africa. The Fagerström test was used to assess nicotine dependence. Chi Square tests and modified Poisson regression analyses were conducted to identify factors associated with tobacco use. RESULTS: Almost half of the participants reported ever smoking (44.0%; CI: 40.1-47.9) and about a quarter reported ever using snuff (25.5%; CI: 22.2-29.1). Current smokers and current snuff users comprised 27.3% (CI: 23.9-30.9) and 19.1% (CI: 16.2-22.3) of all participants respectively. Among current smokers, 37.9% (CI: 30.8-45.3) were moderately/highly dependent on nicotine. Current 'any tobacco product users' (ATPU: use cigarettes or snuff) were 45.4% (CI: 41.5-49.3) while 1.0% (CI: 0.4-2.0) currently used cigarettes and snuff. Adjusted regression analyses showed that, compared to males, females were less at risk of being: ever smokers (Relative Risk Ratio [RRR] = 0.33; CI: 0.27-0.41), current smokers (RRR = 0.18; CI: 0.12-0.25), and ATPU (RRR = 0.75; CI: 0.63-0.89) but were more at risk of ever snuff use (RRR = 5.23; CI: 3.31-8.25), or current snuff use (RRR = 26.19; CI: 8.32-82.40) than males. Ever snuff users (RRR = 1.32; CI: 1.03-1.70), current snuff users (RRR = 1.40; CI: 1.03-1.89) and ATPU (RRR = 1.27; CI: 1.07-1.51) were more at risk of reporting significant depressive symptoms. We found no significant associations between smoking status and years on ART and viral load. CONCLUSION: There is a high prevalence of cigarette and snuff use among PLWH who drink heavily. Tobacco use cessation interventions tailored specifically for this population and according to their tobacco product of choice are urgently needed given their vulnerability to ill-health.

Background: Alcohol harm is a major contributor to the burden of disease in South Africa. This study aimed to identify the extent of heavy drinking and symptoms of alcohol problems among adult drinkers and associated demographic and other risk factors in the Tshwane Metropole of South Africa. Methods: A household survey was conducted using multi-stage stratified cluster random sampling. Heavy drinking was defined as consuming at least 120 mL for men and at least 90 mL for women of absolute alcohol on one occasion at least monthly while symptoms of alcohol problems were measured using the Rapid Alcohol Problems Screen 4 (RAPS4). Stata 14.0 was used for the analysis. Results: Just over half (52%) of the sample reported heavy drinking, and half (50%) reported symptoms of alcohol problems. Gender race/ethnicity, marital status, mode of transport used to purchase alcohol, perceptions of alcohol availability and exposure to alcohol promotions and advertising through SMS and free offers when buying alcohol all impacted heavy drinking. Gender, age, personal income and exposure to alcohol promotions and advertising in magazines and newspapers all impacted symptoms of alcohol problems. Conclusion: The study raises important questions about various policy related mechanisms to curtail heavy drinking and highlights the need for more extensive research to assess the nature and extent of heavy drinking and alcohol problems in South Africa.

BACKGROUND: Globally, illness and life expectancy follow a social gradient that puts people of lower socioeconomic status (SES) at higher risk of dying prematurely. Alcohol consumption has been shown to be a factor contributing to socioeconomic differences in mortality. However, little evidence is available from low- and middle-income countries. The objective of this study was to quantify mortality attributable to alcohol consumption in the adult (15+ years) general population of South Africa in 2015 by SES, age, and sex. METHODS: A comparative risk assessment was performed using individual and aggregate data from South Africa and risk relations reported in the literature. Alcohol-attributable fractions (AAFs) and alcohol-attributable mortality rates were estimated for cause-specific mortality by SES, sex, and age. Monte Carlo simulation techniques were used to calculate 95% uncertainty intervals (UI). RESULTS: Overall, approximately 62,300 (95% UI 27,000-103,000) adults died from alcohol-attributable causes in South Africa in 2015, with 60% of deaths occurring in people in the low and 15% in the high SES groups. Age-standardized, alcohol-attributable mortality rates per 100,000 adults were highest for the low SES group (727 deaths, 95% UI 354-1208 deaths) followed by the middle (377 deaths, 95% UI 165-687 deaths) and high SES groups (163 deaths, 95% UI 71-289 deaths). The socioeconomic differences were highest for mortality from infectious diseases. People of low SES had a lower prevalence of current alcohol use but heavier drinking patterns among current drinkers. Among men, AAFs were elevated at low and middle SES, particularly for the middle and higher age groups (35+). Among women, AAFs differed less across SES groups and, in the youngest age group (15-34), women of high SES had elevated AAFs. CONCLUSIONS: Alcohol use contributed to vast socioeconomic differences in mortality. Where observed, elevated AAFs for people of low and middle SES arose from higher levels of consumption among current drinkers and not from the prevalence of current alcohol use per se. The findings can direct preventive measures and interventions on those at highest risk. Future research is needed to investigate socioeconomic differences in the risk functions relating alcohol use to cause-specific mortality.

RESUMEN
BACKGROUND: An estimated 10% of tuberculosis (TB) deaths are attributable to problematic alcohol use globally, however the causal pathways through which problem alcohol use has an impact on TB treatment outcome is not clear. This study aims to improve understanding of these mechanisms. Specifically, we aim to 1) assess whether poor TB treatment outcomes, measured as delayed time-to-culture conversion, are associated with problem alcohol use after controlling for non-adherence to TB pharmacotherapy; and 2) to determine whether pharmacokinetic (PK) changes in those with problem alcohol use are associated with delayed culture conversion, higher treatment failure/relapse rates or with increased toxicity. METHODS: Our longitudinal, repeated measures, prospective cohort study aims to examine the associations between problem alcohol use and TB treatment outcomes and to evaluate the effect of alcohol on the PK and pharmacodynamics (PD) of TB drugs. We will recruit 438 microbiologically confirmed, pulmonary TB patients with evidence of rifampicin susceptibility in Worcester, South Africa with 200 HIV uninfected patients co-enrolled in the PK aim. Participants are followed for the six months of TB treatment and an additional 12 months thereafter, with sputum collected weekly for the first 12 weeks of treatment, alcohol consumption measures repeated monthly in concert with an alcohol biomarker (phosphatidylethanol) measurement at baseline, and in person directly observed therapy (DOT) using real-time mobile phone-based adherence monitoring. The primary outcome is based on time to culture conversion with the second objective to compare PK of first line TB therapy in those with and without problem alcohol use. DISCUSSION: Globally, an urgent need exists to identify modifiable drivers of poor TB treatment outcomes. There is a critical need for more effective TB treatment strategies for patients with a history of problem alcohol use. However, it is not known whether poor treatment outcomes in alcohol using patients are solely attributable to noncompliance. This study will attempt to answer this question and provide guidance for future TB intervention trials. TRIAL REGISTRATION: Clinicaltrials.gov Registration Number: NCT02840877 .

INTRODUCTION: Little is known about the nature and extent of substance use among pregnant women in Cape Town (South Africa) despite the very high levels of substance use and related consequences such as FASD in this part of the country. The aim of the study was to determine predictors of alcohol use among pregnant women. METHODS: A cross-sectional survey was conducted among pregnant women attending 11 Midwife Obstetric Units (MOUs) in greater Cape Town. A two-stage cluster survey design was used. In total, 5231 pregnant women were screened to assess self-reported prevalence estimates. Of these, 684 (13.1%) were intentionally sub-sampled and completed an interviewer-administered questionnaire and provided a urine sample for biological screening. Univariate and multivariate statistical procedures were used to determine factors predictive of alcohol use. RESULTS: Findings highlight various demographic, social and partner substance use predictors for both self-reported and biologically verified alcohol use in two different models. Being Coloured, having a marital status other than being married, experiencing violence or aggression in the past 12 months compared to more than 12 months ago, having a partner who drinks, and partner drug use are all independently associated with higher odds of self-reported alcohol use. In contrast, only partner tobacco use is independently associated with higher odds of biologically verified alcohol use. CONCLUSION: Knowing the risk factors for alcohol use in pregnancy is important so that intervention efforts can accurately target those women in need of services. Intervention programs addressing risk factors of high-risk pregnant women are needed.

The harmful use of alcohol is a component cause for more than 200 diseases. The association between alcohol consumption, risk taking behavior and a range of infectious diseases such as HIV/AIDS is well established. The prevalence of HIV/AIDS as well as harmful alcohol use in low and middle income countries is high. Alcohol has been identified as a modifiable risk factor in the prevention and treatment of HIV/AIDS. The objective of this paper is to define research priorities for the interaction of alcohol and HIV/AIDS in low and middle income countries. The Child Health and Nutrition Research Initiative (CHNRI) priority setting methodology was applied in order to assess research priorities of the interaction of alcohol and HIV/AIDS. A group of 171 global and local experts in the field of alcohol and or HIV/AIDS related research were identified and invited to generate research questions. This resulted in 205 research questions which have been categorized and refined by senior researchers into 48 research questions to be evaluated using five criteria: answerability, effectiveness, feasibility, applicability and impact, as well as equity. A total of 59 experts participated independently in the voluntary scoring exercise (a 34% response rate). There was substantial consensus among experts on priorities for research on alcohol and HIV. These tended to break down into two categories, those focusing on better understanding the nexus between alcohol and HIV and those directed towards informing practical interventions to reduce the impact of alcohol use on HIV treatment outcomes, which replicates what Bryant (Subst Use Misuse 41:1465-1507, 2006) and Parry et al. (Addiction 108:1-2, 2012) found. Responses from experts were stratified by location in order to determine any differences between groups. On average experts in the LMIC gave higher scores than the HIC experts. Recent research has shown the causal link between alcohol consumption and the incidence of HIV/AIDS including a better understanding of the pathways through which alcohol use affects ARV adherence (and other medications to treat opportunistic infections) and CD4 counts. The results of this process clearly indicated that the important priorities for future research related to the development and assessment of interventions focusing on addressing alcohol and HIV/AIDS, addressing and exploring the impact of HIV risk and comorbid alcohol use, as well as exploring the risk and protective factors in the field of alcohol and HIV/AIDS. The findings from this priority setting exercise could guide international research agenda and make research funding more effective in addressing the research on intersection of alcohol and HIV/AIDS.

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.

Working in an interdisciplinary manner at the crossroads of alcohol and HIV research is a challenge. This paper presents six novel approaches that could be applied to activities at the intersection of alcohol and HIV. These approaches are (i) address the fact that the availability of new technology is unevenly distributed around the world, (ii) use technology to move beyond both paper and digital surveys, (iii) introduce a focus on advocacy and partnerships with large technology companies, (iv) harness technological innovation to utilise digital counselling, (v) explore the use of virtual reality in both research and delivering interventions, and (vi) consider alternative funding models to those currently in existence to improve efficiencies and innovations. Aiming to understand the interplay of alcohol and HIV will require creativity. The six approaches outlines in this paper provide possible directions from which new approaches may emerge.

Although hazardous/harmful alcohol use impacts response to HIV treatment, there have been few attempts to deliver alcohol-reduction interventions within South African HIV treatment services. As a first step towards implementing alcohol-focused interventions in these settings, we explored patients' views of the acceptability of a brief motivational interviewing and problem-solving intervention. In-depth interviews were conducted with 11 patients recruited from three HIV treatment sites in Tshwane, South Africa, who had completed the intervention. Participants noted that the intervention was acceptable and appropriate. As a result of the intervention, participants reported less use of alcohol as a coping mechanism. They described greater use of problem-focused and emotional coping strategies for dealing with mutable and immutable problems, respectively. Their only recommendation for improving the intervention was the addition of booster sessions. Findings suggest that this intervention is acceptable to patients receiving HIV treatment and is perceived to be helpful for reducing their use of alcohol.
