Living With Hiv

Abstract Globally, South Africa ranks worst for people living with HIV (PLHIV) and the unique legacy of internal labour migration continues to be a major driver of the regional epidemic, interrupting treatment-as-prevention efforts. The study examined levels, trends, and predictors of migration in rural KwaZulu-Natal Province, South Africa, using population-based surveillance data from 2005 through 2017. We followed 69 604 adult participants aged 15-49 years and recorded their migration events (i.e., out-migration from the surveillance area) in 423 038 person-years over 525 397 observations. Multiple failure Cox-regression models were used to measure the risk of migration by socio-demographic factors: age, sex, educational status, marital status, HIV, and community antiretroviral therapy (ART) coverage. Overall, 69% of the population cohort experienced at least one migration event during the follow-up period. The average incidence rate of migration was 9.96 events and 13.23 events per 100 person-years in women and men, respectively. Migration rates declined from 2005 to 2008 then peaked in 2012 for both women and men. Adjusting for other covariates, the risk of migration was 3.4-times higher among young women aged 20-24 years compared to those aged ≥40 years (adjusted Hazard Ratio [aHR]=3.37, 95% Confidence Interval [CI]: 3:19-3.57), and 2.9-times higher among young men aged 20-24 years compared to those aged ≥40 years (aHR=2.86, 95% CI:2.69-3.04). There was a 9% and 27% decrease in risk of migration among both women (aHR=0.91, 95% CI: 0.83 – 0.99) and men (aHR=0.73, 95% CI 0.66 – 0.82) respectively per every 1% increase in community ART coverage. Young unmarried women including those living with HIV, migrated at a magnitude similar to that of their male counterparts, and lowered as ART coverage increased over time, reflecting the role of improved HIV services across space in reducing out-migration. A deeper understanding of the characteristics of a migrating population provides critical information towards identifying and addressing gaps in the HIV prevention and care continuum in an era of high mobility.

Background: Privacy-preserving probabilistic record linkage (PPPRL) methods were developed and applied in high-income countries to link records within and between organizations under strict privacy protections. PPPRL has not yet been used in African settings.Methods: We used HIV-related laboratory records from National Health Laboratory Services (NHLS) in South Africa to construct a cohort of HIV-positive patients and link them to the National Cancer Registry (NCR) with PPPRL. The study was restricted to Gauteng province from 2004 to 2014. We used records with national IDs (gold standard) to determine precision, recall, and f-measure of the linkages. We included all patients with ≥ 2 HIV-related lab records measured in the cohort and assessed the number of cancers diagnosed in people living with HIV (PLWH).Results: We included 11,480,118 HIV-related laboratory records and 664,869 cancer records in the linkage. We included 1,173,908 persons in the HIV cohort; 66.6% were female and median age at first HIV-related lab test was 33.9 years (IQR 27.4-41.3). Of the patients in the cohort, 26,348 were diagnosed with at least one cancer and 8,329 of these cancers were diagnosed before or on the date of the patient’s first HIV-related record; 18,019 were diagnosed after their first HIV-related record. For all linkages, precision, recall, and f-measures were high.Conclusion: Our study showed it is feasible to use PPPRL in an African setting to link routinely collected health records from different data sources and create a longitudinal HIV cohort with cancer outcomes while strictly protecting patient privacy. This work served as the foundation to create a nationwide population-based cohort including all South African provinces which will be used to inform cancer control programs.

Background: It is unclear whether HIV infection is associated with risk of COVID-19 death. We aimed to investigate this in a large-scale population-based study in England. Methods: Working on behalf of NHS England, we used the OpenSAFELY platform to analyse routinely collected electronic primary care data linked to national death registrations. People with a primary care record for HIV infection were compared to people without HIV. COVID-19 death was defined by ICD-10 codes U07.1 or U07.2 anywhere on the death certificate. Cox regression models were used to estimate the association between HIV infection and COVID-19 death, initially adjusted for age and sex, then adding adjustment for index of multiple deprivation and ethnicity, and finally for a broad range of comorbidities. Interaction terms were added to assess effect modification by age, sex, ethnicity, comorbidities and calendar time. Results: 17.3 million adults were included, of whom 27,480 (0.16%) had HIV recorded. People living with HIV were more likely to be male, of black ethnicity, and from a more deprived geographical area than the general population. There were 14,882 COVID-19 deaths during the study period, with 25 among people with HIV. People living with HIV had nearly three-fold higher risk of COVID-19 death than those without HIV after adjusting for age and sex (HR=2.90, 95% CI 1.96-4.30). The association was attenuated but risk remained substantially raised, after adjustment for deprivation and ethnicity (adjusted HR=2.52, 1.70-3.73) and further adjustment for comorbidities (HR=2.30, 1.55-3.41). There was some evidence that the association was larger among people of black ethnicity (HR = 3.80, 2.15-6.74, compared to 1.64, 0.92-2.90 in non-black individuals, p-interaction=0.045) Interpretation: HIV infection was associated with a markedly raised risk of COVID-19 death in a country with high levels of antiretroviral therapy coverage and viral suppression; the association was larger in people of black ethnicity.

Since the pharmaceutical turn, using HIV treatment to prevent transmission is increasingly common. Treatment as Prevention®, or TasP, has relied on HIV treatment to prevent HIV transmission, targeting people living with HIV. However, TasP is predicated on troublesome heterosexist, classist, and racist medical practices borrowed from various times and spaces that enact biopolitical and necropolitical relations. This paper discusses the debate surrounding the first clinical trial that used HIV treatment to prevent transmission from woman-to-foetus. The 1994 landmark AIDS Clinical Trials Group 076 study laid the groundwork for using HIV treatment to prevent HIV transmission, the essential precursor to TasP. By examining the concerns of HIV positive women of colour and other AIDS activists, we are able to understand the ethical dilemmas and practical consequences that still haunt today's game-changing uses of HIV treatment for prevention and to see how biopolitics and necropolitics persist in TasP.

ObjectivesAs people living with HIV (PLWH) live longer, morbidity and mortality from non-AIDS comorbidities have emerged as major concerns. Our objective was to compare prevalence trends and age at diagnosis of nine chronic age-associated comorbidities between individuals living with and without HIV.Design and settingThis population-based cohort study used longitudinal cohort data from all diagnosed antiretroviral-treated PLWH and 1:4 age-sex-matched HIV-negative individuals in British Columbia, Canada.ParticipantsThe study included 8031 antiretroviral-treated PLWH and 32 124 HIV-negative controls (median age 40 years, 82% men). Eligible participants were ≥19 years old and followed for ≥1 year during 2000 to 2012.Primary and secondary outcome measuresThe presence of non-AIDS-defining cancers, diabetes, osteoarthritis, hypertension, Alzheimer’s and/or non-HIV-related dementia, cardiovascular, kidney, liver and lung diseases were identified from provincial administrative databases. Beta regression assessed annual age-sex-standardised prevalence trends and Kruskal-Wallis tests compared the age at diagnosis of comorbidities stratified by rate of healthcare encounters.ResultsAcross study period, the prevalence of all chronic age-associated comorbidities, except hypertension, were higher among PLWH compared with their community-based HIV-negative counterparts; as much as 10 times higher for liver diseases (25.3% vs 2.1%, p value<0.0001). On stratification by healthcare encounter rates, PLWH experienced most chronic age-associated significantly earlier than HIV-negative controls, as early as 21 years earlier for Alzheimer’s and/or dementia.ConclusionsPLWH experienced higher prevalence and earlier age at diagnosis of non-AIDS comorbidities than their HIV-negative controls. These results stress the need for optimised screening for comorbidities at earlier ages among PLWH, and a comprehensive HIV care model that integrates prevention and treatment of chronic age-associated conditions. Additionally, the robust methodology developed in this study, which addresses concerns on the use of administrative health data to measure prevalence and incidence, is reproducible to other settings.

Abstract Introduction A higher proportion of people living with HIV (PLWH) smoke compared to the general population, but little information exists about the prevalence and correlates of smokeless tobacco use among PLWH. In South Africa, dry powdered tobacco is inhaled nasally as snuff. Methods A cross-sectional survey among PLWH attending three HIV clinics was conducted. Snuff use was assessed via self-report and urine cotinine. Results Given the low (3%) prevalence of snuff use among men, analysis was restricted to n = 606 nonsmoking women living with HIV. Half (n = 298, 49%) were snuff users, the majority of whom (n = 244, 84%) had a positive urine cotinine test. In adjusted analysis, snuff use was negatively associated with higher education (relative risk [RR] 0.55; 95% confidence interval [CI]: 0.39, 0.77) and mobile phone ownership (RR 0.83; 95% CI: 0.71, 0.98), and positively associated with ever having tuberculosis (TB) (RR 1.22; 95% CI: 1.03, 1.45). In adjusted analysis, with current TB as the outcome, snuff use was marginally statistically significantly associated with a twofold increase in odds of a current TB diagnosis (odds ratio [OR] 1.99; 95% CI: 0.98, 4.15). Discussion A high proportion of nonsmoking South African women living with HIV use snuff, which was a risk factor for TB. Additional research is needed to understand the relationship between snuff, TB, and other potential health risks. Implications PLWH have a higher prevalence of smoking than their seronegative peers, but there is a paucity of research on smokeless tobacco use in this population, especially in low-resource settings. TB is the leading cause of death among PLWH, and with improvements to HIV treatment and care, PLWH are at greater risk of tobacco-related diseases. We report an extremely high prevalence of snuff use among women living with HIV in South Africa. Further, in this population snuff use is positively associated with ever having a TB diagnosis, as well as currently having TB.

Despite increased access to highly active anti-retroviral therapy (HAART) in South Africa, there remains a high risk of people living with HIV (PLHIV) developing a wide range of disabilities. Physiotherapists are trained to rehabilitate individuals with the disabilities related to HIV. Not only can South African physiotherapists play a significant role in improving the lives of PLHIV, but by responding proactively to the HIV epidemic they can reinforce the relevance and value of the profession in this country at a time when many newly qualified therapists are unable to secure employment. This paper offers recommendations that may help to fuel this response. These ideas include enhancing HIV curricula at a tertiary level, designing and attending continuing education courses on HIV and researching Southern African rehabilitation interventions for HIV at all levels of practice. furthermore, it is vital that physiotherapists are at the forefront of directing multi-disciplinary responses to the rehabilitation of PLHIV in order to influence stakeholders who are responsible for health policy formulation. it is hoped that this paper stimulates discussion and further ideas amongst physiotherapists and other health professionals in order to improve the quality and access to care available to PLHIV in South Africa.
