Abstract
BACKGROUND Coronavirus disease (COVID-19) severely disrupted routine health care globally. This study assessed the impact of successive COVID-19 waves on HIV viral load (VL) suppression in South Africa, using the national public sector laboratory database. Guidelines recommend VL monitoring at 6 months after treatment initiation, annually once if suppressed, or more frequently if unsuppressed. METHODS Specimen-level VL data were extracted for the period January 2019-December 2021. We assessed the national percentage of samples with a VL <50 (virological suppression), 50-999 (low-level viremia), and ≥1000 (viremia) copies/mL. Data were analyzed by calendar year and month. Data for 2019 (pre-COVID-19) were compared with the 2020 and 2021 calendar years (lockdowns imposed). The national number of COVID-19 cases was reported to indicate the wave periods as follows: 1 (ancestral)-June-August 2020; 2 (Beta)-December 2020-January 2021; 3 (Delta)-June-August 2021, and 4 (Omicron)-December 2021. RESULTS Data are reported for 17,460,264 samples, with 5,608,733, 5,840,056, and 6,011,475 tests performed in 2019, 2020, and 2021 respectively. Overall, a VL of <50, 50-999, and ≥1000 copies/mL were reported for 69.4%, 17.3%, and 13.4% of samples, respectively. A VL <50 copies/mL was reported for 67.7%, 70.3%, and 70.0% of patients in 2019, 2020, and 2021, respectively. For the 2020 and 2021 calendar years, the monthly percentage of patients with a VL <50 copies/mL ranged between 64.6% and 72.7%. CONCLUSION Our findings indicate that COVID-19 has not had a substantial impact on the percentage of samples with virological suppression at the national level.

Abstract
A large proportion of people living with HIV (PLHIV) in sub-Saharan Africa reside in rural areas. Knowledge of enablers and barriers of adherence to antiretroviral treatment (ART) in these populations is limited. We conducted a cohort study of 501 adult PLHIV on ART at a rural South African treatment facility as a sub-study of a clinical trial (ClinicalTrials.gov NCT03357588). Socio-economic, psychosocial and behavioral characteristics were assessed as covariates of self-reported adherence difficulties, suboptimal pill count adherence and virological failure during 96 weeks of follow-up. Male gender was an independent risk factor for all outcomes. Food insecurity was associated with virological failure in males. Depressive symptoms were independently associated with virological failure in both males and females. Household income and task-oriented coping score were protective against suboptimal pill-count adherence. These results underscore the impact of low household income, food insecurity and depression on outcomes of ART in rural settings and confirm other previously described risk factors. Recognition of these factors and targeted adherence support strategies may improve patient health and treatment outcomes.

Abstract
Cardiovascular disease (CVD) is the leading cause of death globally. The occupational challenges of bus drivers may increase their risk of CVD, including developing obesity, hypertension, and diabetes. We evaluated the medical records of 266 bus drivers visiting an occupational medical practice between 2007 and 2017 in Johannesburg, South Africa, to determine the health status of bus drivers and investigate risk factors for CVD, and their impact on the ability to work. The participants were in majority male (99.3%) with a median age of 41.2 years (IQR 35.2); 23.7% were smokers, and 27.1% consumed alcohol. The median body mass index (BMI) was 26.8 m/kg2 (IQR 7.1), with 63.1% of participants having above normal BMI. Smoking, BMI, and hypertension findings were in line with national South African data, but diabetes prevalence was far lower. Undiagnosed hypertension was found in 9.4% of participants, uncontrolled hypertension in 5.6%, and diabetes in 3.0%. Analysis by BMI category found that obesity was significantly associated with increased odds of hypertension. Uncontrolled hypertension was the main reason for being deemed 'unfit to work' (35.3%). Our research highlights the need for more regular screening for hypertension and interventions to address high BMI.

Abstract
Aim Dolutegravir is associated with more weight gain than efavirenz in people starting antiretroviral therapy (ART). We investigated the concentration-response relationships of efavirenz and dolutegravir with weight gain. Methods We determined concentration-response relationships of dolutegravir and efavirenz (both combined with tenofovir disoproxil fumarate and emtricitabine) with changes in weight and fat distribution, derived from dual-energy x-ray absorptiometry scans, in a nested study of ART-naïve participants from a randomised controlled trial. Pharmacokinetic parameters used in analyses were efavirenz mid-dosing interval (MDI) concentrations and estimated dolutegravir area under the concentration-time curve (AUC0-24) using a population pharmacokinetic model developed in the study population. Study outcomes were percentage changes from baseline to week 48 in weight, and visceral and subcutaneous adipose tissue (VAT and SAT) mass. Results Pharmacokinetic data were available for 158 and 233 participants in the efavirenz arm and dolutegravir arms respectively; 57.0% were women. On multivariable linear regression there were independent negative associations between efavirenz concentrations and changes in both weight (P <0.001) and SAT mass (P = 0.002). Estimated dolutegravir AUC0-24 was not associated with change in weight (P = 0.109) but was negatively associated with change in VAT mass (P = 0.025). Conclusion We found an independent negative concentration-response relationship between efavirenz concentrations and weight change in ART-naïve participants. Dolutegravir concentrations were not independently associated with weight change. These findings suggest that weight gain differences between efavirenz and dolutegravir are driven by efavirenz toxicity impairing weight gain rather than by off-target effects of dolutegravir causing weight gain.

Abstract
Obesity develops in a substantial number of people initiating and maintaining modern antiretroviral therapy. The comorbidities associated with obesity make significant weight gain and metabolic changes a major consideration in clinical trials studying different regimens' potency and safety. It is as yet unclear what role individual antiretrovirals or classes play in weight gain but the issue is a complex one for clinical trial design, especially when deciding when "too much" weight has been gained, in a context where we do not yet know if switching to alternative regimens will slow, halt or reverse weight gain or metabolic changes. In addition, clinician and trial participant opinion on acceptable weight gain may differ. We offer preliminary guidance for discussion for future antiretroviral clinical trial design.

Abstract
Progression in the development of antiretroviral therapy has been remarkable, with new agents continuing to appear as options for modern regimens, including in low-and-middle income countries where the HIV epidemic is concentrated. Here, we reflect on progress made in guiding regimen changes to public health programmes, and the challenges facing selection of newer agents.

Abstract
PURPOSE OF REVIEW HIV treatment has evolved since the introduction of antiretroviral therapy (ART) in the 1990s. Earlier treatment strategies, and the introduction of integrase inhibitors in preferred first-line ART have fundamentally changed cardiovascular side effects due to HIV infection and ART. This review provides an update on cardiovascular toxicity of contemporary ART. RECENT FINDINGS Cardiovascular disease (CVD) risk, including heart failure, is still increased in people living with HIV (PLWH). Exposure to older antiretrovirals, including stavudine and zidovudine, still impact on CVD risk through persistent changes in body fat distribution years after discontinuation. Protease inhibitors (PI) and efavirenz have associated metabolic disturbances and increased risk of CVD, although use is decreasing worldwide. Integrase inhibitors and CCR5 antagonists seem to have negligible immediate CVD toxicity. Weight gain on newer antiretrovirals including integrase inhibitors is a reason for concern. SUMMARY CVD risk should be monitored carefully in PLWH who were exposed to first generation ART, efavirenz or to PIs. Registries should capture ART use and CVD events to stay informed on actual clinical risk in the current era of rapid initiation on integrase inhibitor-based ART.

Abstract
Introduction Insight into inflammation patterns is needed to understand the pathophysiology of HIV and related cardiovascular disease (CVD). We assessed patterns of inflammation related to HIV infection and CVD risk assessed with carotid intima media thickness (CIMT). Methods A cross-sectional study was performed in Johannesburg, South Africa, including participants with HIV who were virally suppressed on anti-retroviral therapy (ART) as well as HIV-negative participants who were family members or friends to the HIV-positive participants. Information was collected on CVD risk factors and CIMT. Inflammation was measured with the Olink panel ‘inflammation’, allowing to simultaneously assess 92 inflammation markers. Differences in inflammation patterns between HIV-positive and HIV-negative participants were explored using a principal component analysis (PCA) and ANCOVA. The impact of differentiating immune markers, as identified by ANCOVA, on CIMT was assessed using linear regression while adjusting for classic CVD risk factors. Results In total, 185 HIV-positive and 104 HIV negative participants, 63% females, median age 40.7 years (IQR 35.4 – 47.7) were included. HIV-positive individuals were older (+6 years, p <0.01) and had a higher CIMT (p <0.01). No clear patterns of inflammation were identified by use of PCA. Following ANCOVA, nine immune markers differed significantly between HIV-positive and HIV-negative participants, including PDL1. PDL1 was independently associated with CIMT, but upon stratification this effect remained for HIV-negative individuals only. Conclusion HIV positive patients on stable ART and HIV negative controls had similar immune activation patterns. CVD risk in HIV-positive participants was mediated by inflammation markers included in this study.

Abstract
Africa's readiness to respond to the SARS-COV-2 pandemic was tested due to reliance on rapid turn-around-time of polymerase chain reaction results for clinical management, isolation and quarantine decisions. The NHLS HIV Molecular Laboratory in Johannesburg, South Africa, is one of the largest automated HIV molecular laboratories worldwide. Despite its extensive molecular capacity and experience in managing high volumes acquired from a large HIV program, significant challenges were encountered during its rapid transition to large scale SARS-CoV-2 testing. We describe the strategies employed to manage these challenges that resulted in a 30% improvement in SARS-CoV-2 test turn-around-time during the first wave peak during which approximately 25000 samples were tested per month, and further improvement during the second wave peak, with 81% within targeted turn-around-time.

Abstract
OBJECTIVES Long-haul truck drivers (TDs) may have lifestyles that promote cardiovascular disease (CVD), including diet, sleep and activity issues. Most studies conducted among truckers investigated the relationship between poor sleep and cardiometabolic health, but none assessed whether suspected obstructive sleep apnoea (OSA) and shortened sleep were associated with markers of cardiometabolic risk. We determined whether sleep disorders and circadian misalignment were associated with chronic inflammation and CVD risk in TDs from Southern Africa. METHODS Participants were recruited at roadside wellness centres in Gauteng and Free State Provinces, South Africa. OSA risk was assessed using the Berlin Questionnaire, while sleep duration and sleep quality were assessed using items from the Pittsburgh Sleep Quality Index. Clinical information, neck circumference (NC), metabolic profile, elevated BP, HIV status and C-reactive protein (CRP) were collected. CVD risk was assessed using the Framingham Risk Score (FRS). RESULTS Out of 575 participants aged on average 37.7 years, 17.2% were at OSA risk, 72.0% had elevated BP, 9.4% had HIV and 28.0% were obese. Mean sleep duration was 7.4±1.8 hours, and 49.6% reported working night shift at least once a week. Shortened sleep, OSA risk, age, body mass index, NC and years as full-time TD were associated with greater FRS independently of HIV status and night shift. Working night shift was associated with higher CRP levels in HIV+ compared with HIV- participants. CONCLUSIONS Circadian misalignment in HIV, and OSA and short sleep duration in all truckers were associated with increased CVD risk. Truckers should be given careful attention in terms of health management and sleep education.

Abstract
Systemic biomarkers of inflammation, including cytokines and chemokines, are potentially useful in the management of both HIV infection and non-AIDS-defining disorders. However, relatively little is known about the utility of measurement of circulating biomarkers of platelet activation as a strategy to monitor the efficacy of combination antiretroviral therapy (cART), as well as the persistence of systemic inflammation following virally-suppressive therapy in HIV-infected persons. These issues have been addressed in the current study to which a cohort consisting of 199 HIV-infected participants was recruited, 100 of whom were cART-naïve and the remainder cART-treated and virally-suppressed. Fifteen healthy control participants were included for comparison. The study focused on the effects of cART on the responsiveness of three biomarkers of platelet activation, specifically soluble CD40 ligand (sCD40L), sCD62P (P-selectin), and platelet-derived growth factor-BB (PDGF-BB), measured using multiplex suspension bead array technology. Most prominently sCD40L in particular, as well as sCD62P, were significantly elevated in the cART-naïve group relative to both the cART-treated and healthy control groups. However, levels of PDGF-BB were of comparable magnitude in both the cART-naïve and -treated groups, and significantly higher than those of the control group. Although remaining somewhat higher in the virally-suppressed group relative to healthy control participants, these findings identify sCD40L, in particular, as a potential biomarker of successful cART, while PDGF-BB may be indicative of persistent low-level antigenemia.

Abstract
Background In South Africa, the trucking industry employs over 70,000 people and the prevalence of chronic pain in this occupational group was reported at 10%. We investigated factors associated with chronic pain in truck drivers including mental health, physical activity, and sleep, as no study has done so. Methods Southern African male, long-distance truck drivers were recruited at truck stops in Gauteng and Free State Provinces, South Africa (n = 614). Chronic pain was defined as pain present for at least the last three months. Depressive symptoms were assessed with the Patient Health Questionnaire-9, post-traumatic stress disorder with the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), exposure to traumatic events with the Life Events Checklist-5 (LEC-5) and daytime sleepiness with the Epworth Sleepiness Scale. Sleep quality was measured on a four-point Likert scale. Leisure-time physical activity was measured using the Godin-Shephard leisure-time physical activity questionnaire. Associations between these factors, demographic factors and chronic pain were investigated. Results Multivariate analysis showed that working ≥ 2 nights/week (OR = 2.68, 95% CI = 1.55–4.68) was associated with chronic pain and physical activity was protective (OR = 0.97, 95% CI 0.95–0.98). In an exploratory analysis, greater depressive symptoms (p = 0.004), daytime sleepiness (p = 0.01) and worse sleep quality (p = 0.001) was associated with working ≥ 2 nights/week. Lower leisure-time physical activity was associated with worse sleep quality (p = 0.006), but not daytime sleepiness or depressive symptoms (p>0.05). Conclusions There is a clear relationship between working nights and activity levels, and chronic pain, sleep quality, and depression in truck drivers.

Abstract
OBJECTIVES Lifestyle and working conditions of truck drivers predisposes them to risk-factors associated with communicable and non-communicable diseases, but little is known about the health status of African truck driver. This study aims to assess a cross-section of truckers in South Africa to describe their health information. SETTING The study took place across three truck-stop rest areas in the South African provinces of Free State and Gauteng. PARTICIPANTS Eligibility criteria included being males aged 18 years and older, full-time employment as a long-distance truck driver. A total of 614 male truck drivers participated; 384 (63%) were Zimbabwean and 325 (55%) completed high-school. PRIMARY AND SECONDARY OUTCOME MEASURES The trucker survey explored demographics; working conditions; sexual, eating and sleeping behaviours; mental health status, medical history and cardiac risk-factors. Medical assessments included physical measurements, glucose and lipid measurements, ECG, carotid intima-media thickness (CIMT) and cardiac ultrasound. RESULTS In the previous month, 554 (91%) participants were sexually active; 522 (86%) had sex with a regular partner; 174 (27%) with a casual partner; 87 (14%) with a sex worker. Average time driving was 10 hours/day, 20 days/month, 302 (50%) never worked night shifts and 74 (12%) worked nights approximately four times per week. 112 (18%) experienced daytime sleepiness and 59 (10%) were ever hospitalised from an accident. Forty-seven (8%, 95% CI 5.3 to 9.5) were HIV-positive, with half taking antiretrovirals. Forty-eight (8%) truckers had some moderate depression, while 21 (4%) suffered from post-traumatic stress disorder. Reported tuberculosis, myocardial infarction, and diabetes were <3%. Prominent cardiac risk-factors included smoking (n=63, 11%), consuming alcohol (>15 drinks/week) (n=54, 9%), overweight/obesity (n=417, 69%), and hypertension (n=220, 36%,95% CI 32.1 to 39.7). ECG results showed 23 (4.9%) and 29 (5.3%) drivers had left ventricular hypertrophy using the Cornell criterion and product, respectively. CIMT measurements indicated nine (4.2%) drivers had a carotid atherosclerotic plaque. CONCLUSION This first holistic assessment of health among southern African male truck drivers demonstrates substantial addressable cardiovascular risk factors, mental health issues and sexual risk behaviours.

Abstract
INTRODUCTION To achieve epidemic control of HIV by 2030, countries aim to meet 90-90-90 targets to increase knowledge of HIV-positive status, initiation of antiretroviral therapy (ART) and viral suppression by 2020. We assessed the progress towards these targets from 2014 to 2016 in South Africa as expanded treatment policies were introduced using population-representative surveys. METHODS Data were collected in January to March 2014 and August to November 2016 in Dr. Ruth Segomotsi Mompati District, North West Province. Each multi-stage cluster sample included 46 enumeration areas (EA), a target of 36 dwelling units (DU) per EA, and a single resident aged 18 to 49 per DU. Data collection included behavioural surveys, rapid HIV antibody testing and dried blood spot collection. We used weighted general linear regression to evaluate differences in the HIV care continuum over time. RESULTS Overall, 1044 and 971 participants enrolled in 2014 and 2016 respectively with approximately 77% undergoing HIV testing. Despite increases in reported testing, known status among people living with HIV (PLHIV) remained similar at 68.7% (95% Confidence Interval (CI) = 60.9-75.6) in 2014 and 72.8% (95% CI = 63.6-80.4) in 2016. Men were consistently less likely than women to know their status. Among those with known status, PLHIV on ART increased significantly from 80.9% (95% CI = 71.9-87.4) to 91.5% (95% CI = 84.4-95.5). Viral suppression (<5000 copies/mL using DBS) among those on ART increased significantly from 55.0% (95% CI = 39.6-70.4) in 2014 to 81.4% (95% CI = 72.0-90.8) in 2016. Among all PLHIV an estimated 72.0% (95% CI = 63.8-80.1) of women and 45.8% (95% CI = 27.0-64.7) of men achieved viral suppression by 2016. CONCLUSIONS Over a period during which fixed-dose combination was introduced, ART eligibility expanded, and efforts to streamline treatment were implemented, major improvements in the second and third 90-90-90 targets were achieved. Achieving the first 90 target will require targeted and improved testing models for men.

Abstract
Like HIV infection, smoking, which is common among HIV-infected persons, is associated with chronic, systemic inflammation. However, the possible augmentative effects of HIV infection and smoking and other types of tobacco usage on indices of systemic inflammation and the impact of combination antiretroviral therapy (cART) thereon remain largely unexplored and represent the focus of the current study. Of the total number of HIV-infected persons recruited to the study (n = 199), 100 were categorised as pre-cART and 99 as virally suppressed (HIV viral load < 40 copies/mL). According to serum cotinine levels, 144 and 55 participants were categorised as nonusers and users of tobacco, respectively. In addition to cytokines (IL-6, IL-8, and TNF-α) and chemokines (IP-10, MIG, IL-8, MCP-1, and RANTES), other biomarkers of systemic inflammation included C-reactive protein (CRP), β2-microglobulin, and those of neutrophil activation [ICAM-1, L-selectin, matrix metalloproteinase-9 (MMP-9)], microbial translocation (soluble CD14, LPS-binding protein), and oxidative stress (cyclophilin A, surfactant D). These were measured using multiplex bead array, ELISA, and immunonephelometric procedures. Viral suppression was associated with significant decreases in the levels of most of the biomarkers tested (P < 0.0037-0.0008), with the exceptions of CRP, cyclophilin A, and MMP-9. With respect to tobacco usage, irrespective of cART status, circulating levels of β2-microglobulin, cyclophilin A, and RANTES were significantly elevated (P < 0.042-0.012) in users vs nonusers. Additional analysis of the groups of tobacco users and nonusers according to cART status revealed high levels of RANTES in pre-cART/tobacco users relative to the three other subgroups (P < 0.004-0.0001), while more modest increases in cyclophilin A and MMP-9 (P < 0.019-0.027) were observed in comparison with the cART/tobacco user subgroup. Notwithstanding the efficacy of cART in attenuating HIV-associated, chronic systemic inflammation, the current study has identified RANTES as being significantly and seemingly selectively increased in those with active HIV infection who use tobacco, a mechanism which may underpin augmentative proinflammatory activity.

Abstract
BACKGROUND The World Health Organization recommends rapid (≤ 7 days) or same-day initiation of antiretroviral treatment (ART) for HIV-positive patients. South Africa adopted this recommendation in 2017, but multiple clinic visits, long waiting times, and delays for laboratory tests remain common. Streamlined approaches to same-day initiation that allow the majority of patients to start ART immediately, while ensuring that patients who do require additional services receive them, are needed to achieve national and international treatment program goals. METHODS/DESIGN The SLATE II (Simplified Algorithm for Treatment Eligibility) study is an individually randomized evaluation of a clinical algorithm to reliably determine a patient's eligibility for immediate ART initiation without waiting for laboratory results or additional clinic visits. It differs from the earlier SLATE I study in management of patients with symptoms of tuberculosis (under SLATE II these patients may be started on ART immediately) and other criteria for immediate initiation. SLATE II will randomize (1:1) 600 adult, HIV-positive patients who present for HIV testing or care and are not yet on ART in South Africa. Patients randomized to the standard arm will receive standard-of-care ART initiation from clinic staff. Patients randomized to the intervention arm will be administered a symptom report, medical history, brief physical exam, and readiness assessment. Symptomatic patients will also have a tuberculosis (TB) module with lipoarabinomannan antigen of mycobacteria test. Patients who have satisfactory results for all four components will be dispensed antiretrovirals (ARVs) immediately, at the same clinic visit. Patients who have any negative results will be referred for further investigation, care, counseling, tests, or other services prior to being dispensed ARVs. Follow-up will be by passive medical record review. The primary outcomes will be ART initiation in ≤ 7 days and retention in care 8 months after study enrollment. DISCUSSION SLATE II improves upon the SLATE I study by reducing the number of reasons for delaying ART initiation and allowing more patients with TB symptoms to start ART on the day of diagnosis. If successful, SLATE II will provide a simple and streamlined approach that can readily be adopted in other settings without investment in additional technology.

Abstract
BACKGROUND Operational research is required to design delivery of pre-exposure prophylaxis (PrEP) and early antiretroviral treatment (ART). This paper presents the primary analysis of programmatic data, as well as demographic, behavioural, and clinical data, from the TAPS Demonstration Project, which offered both interventions to female sex workers (FSWs) at 2 urban clinic sites in South Africa. METHODS AND FINDINGS The TAPS study was conducted between 30 March 2015 and 30 June 2017, with the enrolment period ending on 31 July 2016. TAPS was a prospective observational cohort study with 2 groups receiving interventions delivered in existing service settings: (1) PrEP as part of combination prevention for HIV-negative FSWs and (2) early ART for HIV-positive FSWs. The main outcome was programme retention at 12 months of follow-up. Of the 947 FSWs initially seen in clinic, 692 were HIV tested. HIV prevalence was 49%. Among those returning to clinic after HIV testing and clinical screening, 93% of the women who were HIV-negative were confirmed as clinically eligible for PrEP (n = 224/241), and 41% (n = 110/270) of the women who were HIV-positive had CD4 counts within National Department of Health ART initiation guidelines at assessment. Of the remaining women who were HIV-positive, 93% were eligible for early ART (n = 148/160). From those eligible, 98% (n = 219/224) and 94% (n = 139/148) took up PrEP and early ART, respectively. At baseline, a substantial fraction of women had a steady partner, worked in brothels, and were born in Zimbabwe. Of those enrolled, 22% on PrEP (n = 49/219) and 60% on early ART (n = 83/139) were seen at 12 months; we observed high rates of loss to follow-up: 71% (n = 156/219) and 30% (n = 42/139) in the PrEP and early ART groups, respectively. Little change over time was reported in consistent condom use or the number of sexual partners in the last 7 days, with high levels of consistent condom use with clients and low use with steady partners in both study groups. There were no seroconversions on PrEP and 7 virological failures on early ART among women remaining in the study. Reported adherence to PrEP varied over time between 70% and 85%, whereas over 90% of participants reported taking pills daily while on early ART. Data on provider-side costs were also collected and analysed. The total cost of service delivery was approximately US$126 for PrEP and US$406 for early ART per person-year. The main limitations of this study include the lack of a control group, which was not included due to ethical considerations; clinical study requirements imposed when PrEP was not approved through the regulatory system, which could have affected uptake; and the timing of the implementation of a national sex worker HIV programme, which could have also affected uptake and retention. CONCLUSIONS PrEP and early ART services can be implemented within FSW routine services in high prevalence, urban settings. We observed good uptake for both PrEP and early ART; however, retention rates for PrEP were low. Retention rates for early ART were similar to retention rates for the current standard of care. While the cost of the interventions was higher than previously published, there is potential for cost reduction at scale. The TAPS Demonstration Project results provided the basis for the first government PrEP and early ART guidelines and the rollout of the national sex worker HIV programme in South Africa.

Abstract
BACKGROUND Long-distance truck drivers are occupationally susceptible to poor health outcomes. Their patterns of healthcare utilisation and the suitability of healthcare services available to them are not well documented. We report on truck driver healthcare utilisation across South Africa and characterise the client population of the clinics serving them for future service development. METHODS We analysed anonymised data routinely collected over a two-year period at nine Roadside Wellness Centres. Associations between services accessed and socio-demographic characteristics were assessed using univariable and multivariable logistic regression models. RESULTS We recorded 16,688 visits by 13,252 individual truck drivers (average of 1.26 visits/person) who accessed 17,885 services for an average of 1.07 services/visit and 1.35 services/person. The mean age of truck drivers was 39 years. Sixty-seven percent reported being in stable relationships. The most accessed services were primary healthcare (PHC)(62%) followed by HIV (32%). Low proportions (≤6%) accessed STI,TB and malaria services. Most visits were characterised by only one service being accessed (93%, n = 15,523/16,688). Of the remaining 7% of visits, up to five services were accessed per visit and the combination of TB /HIV services in one visit remained extremely low (<1%, n = 14/16,688). Besides PHC services at the beginning of the reporting period, all service categories displayed similar seasonal utilisation trends(i.e. service utilisation peaked in the immediate few months post clinics opening and substantially decreased before holidays). Across all service categories, younger truck drivers, those with a stable partner currently, and those of South African origin were the main clinic attendees. Older truck drivers (≥40 years) were more likely to access TB and PHC services, yet less likely to access HIV and STI services. Those with stable partners were less likely to access STI and TB services but more likely to access malaria and PHC services. South African attendees were more likely to access PHC, while attendees from other nationalities were more likely to access HIV and malaria services. CONCLUSIONS This utilisation analysis shows that tailored services assist in alleviating healthcare access challenges faced by truck drivers, but it underscores the importance of ensuring that service packages and clinics speak to truck drivers' needs in terms of services offered and clinic location.

Abstract
INTRODUCTION Updated guidelines from the WHO recommend antiretroviral treatment for adults with HIV at any CD4 count and daily oral pre-exposure prophylaxis (PrEP) for people at substantial risk of HIV infection. However, implementation challenges may hinder the ability of programmes to translate these recommendations into successful practice. This demonstration project is the first to integrate PrEP and immediate treatment (ITx) for female sex workers (FSWs) in South Africa to answer operational research questions. METHODS AND ANALYSIS This is a prospective cohort study where the main outcome is retention at 12 months. The study population is recruited into two arms across two urban sites: (1) PrEP for HIV-negative FSWs (n=400) and (2) ITx for HIV-positive FSWs with CD4 greater than national guidelines (n=300). We investigate process and other health indicators, uptake and use of PrEP and ITx through qualitative research, and evaluate cost-effectiveness analysis combined with estimates of impact through epidemiological modelling. ETHICS AND DISSEMINATION The Treatment And Prevention for female Sex workers in South Africa (TAPS) Project was designed as an implementation study before emtricitabine/tenofovir disoproxil fumarate was licenced as an indication for PrEP in South Africa. Therefore, clinical trial requirements for ethical and South African Medicines Control Council approvals were followed. Results will be disseminated to participants, local health officials and other stakeholders, as well as in peer-reviewed journals and at conferences.

Abstract
BACKGROUND Truck drivers have unique health needs, and by virtue of their continuous travel, experience difficulty in accessing healthcare. Currently, planning for effective care is hindered by lack of knowledge about their health needs and about the impact of on-going programmes on this population's health outcomes. We reviewed healthcare programmes implemented for sub-Saharan African truck drivers, assessed the evaluation methods, and examined impact on health outcomes. METHODS We searched scientific and institutional databases, and online search engines to include all publications describing a healthcare programme in sub-Saharan Africa where the main clients were truck drivers. We consulted experts and organisations working with mobile populations to identify unpublished reports. Forest plots of impact and outcome indicators with unadjusted risk ratios and 95% confidence intervals were created to map the impact of these programmes. We performed a subgroup analysis by type of indicator using a random-effects model to assess between-study heterogeneity. We conducted a sensitivity analysis to examine both the summary effect estimate chosen (risk difference vs. risk ratio) and model to summarise results (fixed vs. random effects). RESULTS Thirty-seven publications describing 22 healthcare programmes across 30 countries were included from 5,599 unique records. All programmes had an HIV-prevention focus with only three expanding their services to cover conditions other primary healthcare services. Twelve programmes were evaluated and most evaluations assessed changes in input, output, and outcome indicators. Absence of comparison groups, preventing attribution of the effect observed to the programme and lack of biologically confirmed outcomes were the main limitations. Four programmes estimated a quantitative change in HIV prevalence or reported STI incidence, with mixed results, and one provided anecdotal evidence of changes in AIDS-related mortality and social norms. Most programmes showed positive changes in risk behaviours, knowledge, and attitudes. Our conclusions were robust in sensitivity analyses. CONCLUSION Diverse healthcare programmes tailored to the needs of truck drivers implemented in 30 sub-Saharan African countries have shown potential benefits. However, information gaps about availability of services and their effects impede further planning and implementation of effective healthcare programmes for truck drivers.

Abstract
For the past 25 years, South Africa has had to deal with the inexorable and monumental rise of HIV. From one or two isolated cases, in the late 1980s, South Africa now has an estimated 6.4 million people infected with HIV, with high rates of concomitant tuberculosis, which will profoundly affect the country for decades to come. For nearly 10 years, the South African government's response to the HIV epidemic was described as denialist, which was estimated to have resulted in the deaths of 330,000 people because lifesaving antiretroviral therapy (ART) was not provided (Chigwedere et al. J Acquir Immune Defic Syndr. 49:410-15, 2008; Heywood 2004). However, the story of the HIV and AIDS response in South Africa over the past 5 years is one of great progress after almost a decade of complex and tragic denialism that united civil society in a way not seen since the opposition to apartheid. Today, South Africa can boast of close to 3 million people on ART, by far the largest number in the world. Prevention efforts appear to be yielding results but there continues to be large numbers of new infections, with a profound peak in incidence in young women aged 15 to 24 years. In addition, infections occur across the gender spectrum in older age groups. As a result of the massive increase in access to ART after 2004 and particularly after 2008 as political will towards the HIV ART programme improved, there has been a marked increase in life expectancy, from 56 to 61 years in the period 2009-2012 alone; the aggressive expansion of the prevention of mother to child transmission (PMTCT) to HIV-positive pregnant women has been accompanied by dramatic decrease in HIV transmission to infants; and a 25 % decrease in child and infant mortality rates in the period 2009-2012. This progress in access is significantly due to a civil society movement that was prepared to pose a rights-based challenge to a governing party in denial and to brave health officials, politicians and clinicians working in a hostile system to bring about change.

Abstract
SETTING In South Africa, health care workers (HCWs) are at two-fold greater risk of acquiring tuberculosis (TB) disease than the general population. Few studies have evaluated the risk of incident tuberculous infection. OBJECTIVE To determine the incidence and risk factors for latent tuberculous infection (LTBI) among HCWs and to compare the results of the interferon-gamma release assay (IGRA) with those of the tuberculin skin test (TST). DESIGN HCWs, including medical students, underwent a TST and human immunodeficiency virus (HIV) and IGRA testing at baseline and 12 months, and IGRA at 6 months. The participants kept 12-month TB exposure logs. RESULTS Among 199 participants (150 [76%] females, median age 31 years [range 20-61]), incident LTBI was documented using IGRA in 25/97 (26%; incident rate 29 cases/100 person-years [py], 95%CI 20-44) and using TST in 25/93 (27%; incident rate 29 cases/100 py, 95%CI 19-42). Agreement between TST and IGRA was poor (44.8%, κ = 0.23). Higher annual exposure to TB cases was reported among persons with LTBI than in those who were persistently IGRA-negative (81 cases, 95%CI 61-102 vs. 50 cases, 95%CI 43-57, P < 0.01). CONCLUSION The high LTBI incidence and the association of incident LTBI with annual TB caseload among HCWs indicate that more effective TB infection control should be implemented in South African health care facilities.

Abstract
As antiretroviral treatment has led to decreased morbidity, HIV testing policy has increasingly shifted towards routine, provider-initiated approaches. Yet, few studies have examined the acceptability of provider-initiated HIV testing in the intensive, or critical care setting, where knowledge of HIV status is likely to impact on clinical management but explicit consent for testing is difficult to obtain. We conducted qualitative research in an urban hospital and clinic in Johannesburg. In-depth interviews were conducted among HIV testing clients (n = 20), recently discharged critical care patients (n = 13) and family members of critical care patients (n = 14). One focus group discussion was held with health care providers (n = 10). HIV testing in critical care was viewed as acceptable but challenging to implement. An overarching theme of ambivalence emerged from patients and families, who saw HIV testing as a pre-requisite to appropriate clinical care, but were concerned about the quality of its delivery. While providers were aware of the current "no testing without consent" policy, they expressed frustration in cases when testing was in the patient's best interest but consent could not be obtained. Furthermore, providers found it stressful to weigh up patient confidentiality against medical necessity when assessing patients' "best interests". Without specific guidelines, they often developed pragmatic, ad hoc ways to resolve dilemmas around testing in critical care. Our findings suggest that HIV testing guidelines specific to the critical care setting may help providers do their jobs more ethically and transparently. Provider-initiated approaches are likely to be acceptable to patients and may improve clinical outcomes, but training and support in policy implementation and ethical decision-making are essential.

Abstract
A widely accepted explanation of the dramatically high rates of HIV infection in sub-Saharan Africa appeals to a supposedly distinct model of sexual partnering, referred to as 'multiple concurrent partnerships' or 'concurrency.' We discuss two problems with the concurrency explanation, and argue that it does not contribute to understanding the unusual rates of HIV infection in the region. We argue that there is no single 'concurrency hypothesis,' and the term 'concurrency' is imprecise and does not pick out an explanatorily distinct form of sexual behavior.

Abstract
Background Mortality in the first months of antiretroviral therapy (ART) is a significant clinical problem in sub-Saharan Africa. To date, no post-mortem study has investigated the causes of mortality in these patients. Methods HIV-positive adults who died as in-patients at a Johannesburg academic hospital underwent chart-review and ultrasound-guided needle autopsy for histological and microbiological examination of lung, liver, spleen, kidney, bone marrow, lymph node, skin and cerebrospinal fluid. A clinico-pathologic committee considered all available data and adjudicated immediate and contributing causes of death. Results Thirty-nine adults were enrolled: 14 pre-ART, 15 early-ART (7–90 days), and 10 late-ART (>90 days). Needle sampling yielded adequate specimen in 100% of kidney, skin, heart and cerebrospinal fluid samples, 97% of livers and lungs, 92% of bone marrows, 87% of spleens and 68% of lymph nodes. Mycobacterial infections were implicated in 69% of deaths (26 of 27 of these due to M. tuberculosis), bacterial infections in 33%, fungal infections in 21%, neoplasm in 26%, and non-infectious organ failure in 26%. Immune reconstitution inflammatory syndrome (IRIS) was implicated in 73% of early-ART deaths. Post-mortem investigations revealed previously undiagnosed causes of death in 49% of cases. Multiple pathologies were common with 62% of subjects with mycobacterial infection also having at least one other infectious or neoplastic cause of death. Conclusions Needle biopsy was efficient and yielded excellent pathology. The large majority of deaths in all three groups were caused by M. tuberculosis suggesting an urgent need for improved diagnosis and expedited treatment prior to and throughout the course of antiretroviral therapy. Complex, unrecognized co-morbidities pose an additional challenge.

Abstract
In a South African context, we consider the implications of the United States Food and Drug Administration’s recent approval of the OraQuick HIV self-testing kit. We argue that current law and policy inhibit the roll-out of accurate and well-regulated self-testing kits, and create a loophole for sale in supermarkets, but not pharmacies.

Abstract
Introduction The authors report on a health systems strengthening intervention using quality improvement (QI) methods at the subdistrict level to accelerate highly active antiretroviral treatment (HAART) initiation in South Africa. Methods Using a phased scale-up design between August 2006 and November 2009, 14 primary healthcare clinics, one community health centre, one district hospital and one tertiary hospital in a subdistrict were recruited into a ‘learning network’ using QI methods to facilitate cross-facility learning/mentorship/support. Clinic teams consisting of nurses, counsellors, clerks and/or doctors set collective and individual performance targets, analysed their care systems using ‘real-time’ data feedback, and designed/implemented a set of simple changes to improve HIV testing and HAART initiation rates across the region. Data analysis Primary clinic data were used to measure HAART initiation rates (primary outcome) and HIV testing (secondary outcome). We analysed data variation/trends using an interrupted time series design. Logistic regression analysis was applied to examine trends in HAART initiation during the intervention phases. Results Clinics in the learning network increased HIV testing by 301.8% from 891/month (SD=94.2) to 3580/month (SD=327.7) (p<0.0001). Monthly HAART initiations increased by 185.5% from 179/month (SD=17.22) to 511/month (SD=44.93) (p<0.0001). During the pilot (phase I), the monthly rate of HAART initiations increased by 3.6 patients. In the prototype collaborative (phase II), there was no acceleration in the rate of increase (3.3/month, p=0.92). Significant acceleration was observed in the rate of increase during the QI scale up (phase III) (10.1/month, p<0.001). The proportion of estimated need for HAART met in the region increased from 35.8% to 72.4% at a time of rapid population growth. Conclusion A QI approach, using learning networks to teach simple data-driven methods for addressing system failures, with increased training and resource inputs, can assist districts to quickly reach universal coverage targets.

Abstract
The debate around relooking at stavudine dosing, both in terms of the adult low-dose stavudine study and more broadly, is welcome. The study being proposed to evaluate low-dose stavudine v. tenofovir is a fairly standard placebo-controlled non-inferiority study. The study design is not controversial; however, the choice of study drug has attracted critical attention.

Abstract
Foreigners, including displaced persons, often have limited health-care access, especially to HIV services. Outcomes of antiretroviral therapy (ART) in South Africans and foreigners were compared at a Johannesburg non-governmental clinic. Records were reviewed of 1297 adults enrolled between April 2004 and March 2007 (568 self-identified foreigners, 431 South Africans citizens and 298 with unknown origin). Compared with citizens, foreigners had fewer hospital admissions (39%, 90/303 versus 51%, 126/244; P < 0.001), less missed appointments for ART initiation (20%, 39/200 versus 25%, 51/206; P < 0.001), faster median time to ART initiation (14 versus 21 days, P = 0.008), better retention in care (88%, 325/369 versus 69%, 155/226; P < 0.001) and lower mortality (2.5%, 14/568 versus 10%, 44/431; P < 0.001) after 426 person-years. In logistic regression, after controlling for baseline CD4 count and tuberculosis status, foreigners were 55% less likely to fail ART than citizens (95% CI = 0.23–0.87). These findings support United Nations High Commissioner for Refugees recommendations that ART should not be withheld from displaced persons.

Abstract
OBJECTIVE To ascertain the immediate and underlying causes of death in adults who died in hospital with a premortem diagnosis of tuberculosis. DESIGN Causes of death were assessed independently by internists and pathologists in 50 adults admitted to two Soweto hospitals who died 24 h or more after admission. Detailed record reviews and complete autopsies, including HIV tests when not performed premortem, were performed. In addition, a variety of postmortem microbiological tests were performed. RESULTS Forty-seven patients had HIV infection; all were antiretroviral naive. Their median age was 34.5 years, median CD4 cell count was 48 cells/microl and median length of hospitalization before death was 6 days. Autopsy confirmed the premortem diagnosis of tuberculosis in 37 HIV-infected patients (79%), whereas 10 (21%) did not demonstrate tuberculosis. Bronchopneumonia and cytomegalovirus pneumonitis were the leading pathologies in these 10 patients. In 47 HIV-infected cadavers immediate or contributory causes of death were: extensive pulmonary tuberculosis, 32 (68%); disseminated tuberculosis, 28 (60%); bacterial pneumonia, 13 (26%); cytomegalovirus pneumonitis in seven (15%); cytomegalovirus DNA was found in 31 (66%) and Pneumocystis pneumonia was found in five cadavers (11%). The lung, followed by lymph nodes, liver and kidney, were the commonest sites of tuberculosis. Mycobacterium tuberculosis was cultured from 19 spleens, one of which was multidrug resistant, and Salmonella spp. was cultured from 11 splenic specimens. CONCLUSION We demonstrated disseminated, extensive tuberculosis associated with advanced HIV disease. Severe bacterial infections, including salmonellosis, were the leading co-morbidity, suggesting that hospitalized HIV-infected adults in whom tuberculosis is suspected may benefit from broad-spectrum antibiotic therapy.

Abstract
This prospective non-randomized study of clinic attendees, compares self-reported HIV disclosure patterns in relation to access to antiretroviral access and counselling. It was carried out in public sector hospital HIV clinics in Johannesburg, South Africa, and 144 HIV-positive men and women attending the HIV clinics participated in the study.The results showed that there was no correlation between being on antiretroviral therapy and disclosure of HIV status. There was also no correlation between disclosure of HIV status and with different levels of counselling and access to support groups. Disclosure levels were high (92% told at least one person), however, there was a high level of delayed (15% greater than a year) or non-disclosure (21%) to partners. Family members and partners provided most moral support after disclosure. Having access to antiretroviral therapy and support groups and available counselling did not seem to affect disclosure patterns. It is possible that a patients beliefs about their treatment plays a more important role for disclosure than the actual treatment itself. Other factors are also likely important for disclosure, such as the patient's social network especially with their families, and knowledge of the disease.

Abstract
OBJECTIVE To assess whether adrenocortical function was compromised in patients with active tuberculosis (TB) during the first 5 days of therapy with either a rifampicin-based or ciprofloxacin-based regimen. DESIGN Patients were randomised into two groups of 10 each. Adrenocortical function was compared in both groups by the measurement of biochemical indices, electrolytes, osmolality and pituitary-adrenocortical hormones. Adrenal reserve was assessed by intravenous 250 mug adrenocorticotropin hormone (ACTH) stimulation tests. SETTING Department of Medicine, Johannesburg Hospital. SUBJECTS Twenty hospitalised patients who were diagnosed with TB. OUTCOME MEASURES Respiratory rate, pulse rate and blood pressure were recorded, and urinary sodium and osmolality were measured. Serum ACTH, cortisol, dehydroepiandrosterone- sulphate (DHEA-S) and aldosterone were assayed. RESULTS None of the patients demonstrated biochemical evidence of overt adrenal insufficiency. There were no significant differences between the two groups before or during therapy for any biochemical indices, electrolytes, hormones or calculated osmolality. Mean basal cortisol concentrations were substantially elevated and DHEA-S levels were consistently subnormal, resulting in a high cortisol/ DHEA-S ratio. In the ciprofloxacin group, cortisol responses to ACTH stimulation on day 1 were not significantly lower than on day 5. In the rifampicin group, cortisol concentrations decreased at each time point on day 5 compared with day 1 (p = 0.001). However, a significantly higher mean incremental rise from the basal cortisol concentration was measured on day 5 at 60 minutes (p = 0.04). In the entire cohort of 20 patients, 40% demonstrated an incremental cortisol rise of < 250 nmol/l after ACTH stimulation on day 1. CONCLUSIONS Rifampicin did not additionally impair adrenocortical function during the initial period of therapy. The high cortisol/DHEA-S ratio might be of clinical relevance.

Abstract
Antiretroviral therapy has changed the face of the treatment of HIV throughout the world, converting a fatal into a chronic disease. HIV has reached disastrous levels of infection in southern Africa, and increased use of life-saving therapy is being implemented. The antiretrovirals have a variety of metabolic side effects that have been implicated in cardiovascular disease in other populations. This article discusses the impact of HIV on southern Africa, the metabolic and cardiac complications of both HIV and antiretrovirals, and strategies for dealing with drug side effects.
