Rollout Of Antiretroviral Treatment Research Articles

Despite delayed kinetics, people living with HIV achieve equivalent antibody function after SARS-CoV-2 infection or vaccination.

The kinetics of Fc-mediated functions following SARS-CoV-2 infection or vaccination in people living with HIV (PLWH) are not known. We compared SARS-CoV-2 spike-specific Fc functions, binding, and neutralization in PLWH and people without HIV (PWOH) during acute infection (without prior vaccination) with either the D614G or Beta variants of SARS-CoV-2, or vaccination with ChAdOx1 nCoV-19. Antiretroviral treatment (ART)-naïve PLWH had significantly lower levels of IgG binding, neutralization, and antibody-dependent cellular phagocytosis (ADCP) compared with PLWH on ART. The magnitude of antibody-dependent cellular cytotoxicity (ADCC), complement deposition (ADCD), and cellular trogocytosis (ADCT) was differentially triggered by D614G and Beta. The kinetics of spike IgG-binding antibodies, ADCC, and ADCD were similar, irrespective of the infecting variant between PWOH and PLWH overall. However, compared with PWOH, PLWH infected with D614G had delayed neutralization and ADCP. Furthermore, Beta infection resulted in delayed ADCT, regardless of HIV status. Despite these delays, we observed improved coordination between binding and neutralizing responses and Fc functions in PLWH. In contrast to D614G infection, binding responses in PLWH following ChAdOx-1 nCoV-19 vaccination were delayed, while neutralization and ADCP had similar timing of onset, but lower magnitude, and ADCC was significantly higher than in PWOH. Overall, despite delayed and differential kinetics, PLWH on ART develop comparable responses to PWOH, supporting the prioritization of ART rollout and SARS-CoV-2 vaccination in PLWH.

Kaposi sarcoma-associated herpesvirus, HIV-1 and Kaposi sarcoma risk in black South Africans diagnosed with cancer during antiretroviral treatment rollout.

Kaposi sarcoma-associated herpesvirus (KSHV) causes Kaposi sarcoma (KS). The risk of KS is amplified in HIV-immunosuppressed individuals and antiretroviral therapy (ART) reduces KS incidence. Reliable data on the relationship between these factors are lacking in Africa. We used questionnaires and serum from 7886 black South Africans (18-74 years) with incident cancer, recruited between 1995 and 2016. ART rollout started in 2004. We measured associations between KS, HIV-1 and KSHV before and after ART rollout. We measured seropositivity to HIV-1, KSHV latency-associated nuclear antigen (LANA) and glycoprotein (K8.1) and calculated case-control-adjusted odds ratios (ORadj ) and 95% confidence intervals (CI) in relation to KS and KSHV infection, before (1995-2004), early (2005-2009) and late (2010-2016) ART rollout periods. KSHV seropositivity among 1237 KS cases was 98%. Among 6649 controls, KSHV seropositivity was higher in males (ORadj =1.4 [95%CI 1.23-1.52]), in persons with HIV, (ORadj =4.2 [95%CI 3.74-4.73]) and lower in high school leavers (ORadj =0.7 [95%CI 0.59-0.83]). KSHV seropositivity declined over the three ART rollout periods (37%, 28% and 28%, Ptrend < .001) coinciding with increases in high school leavers over the same periods (46%, 58% and 67%, Ptrend < .001). HIV-1 seroprevalence increased from 10% in the pre-ART period to 22% in the late ART period (Ptrend < .001). Compared to HIV-1 and KSHV seronegatives, KSHV seropositives yielded an OR for KS of 26 (95%CI 11-62) in HIV-1 seronegative participants and an OR of 2501 (95%CI 1083-5776) in HIV-1 seropositive participants. HIV-1 increases the risk of KS in those infected with KSHV by 100-fold. Declines in KSHV seroprevalence coincide with ART rollout and with improvements in educational standards and general hygiene.

The influence of HIV infection and antiretroviral treatment on pulmonary function in individuals in an urban setting in sub-Saharan Africa.

BackgroundWith the roll-out of antiretroviral treatment (ART), the life expectancy of people with HIV and, hence, morbidity from non-communicable diseases, including pulmonary diseases, have increased.ObjectivesThis research study aims to investigate whether HIV infection and ART use are associated with pulmonary function, given the high frequency of pulmonary infections, including tuberculosis (TB), associated with HIV.MethodAdults living with HIV (ART-naïve, on first- or second-line ART), and age and sex matched HIV-negative controls were included in a cross-sectional study in Johannesburg, South Africa. Spirometry was performed to determine lung function, measuring the forced expiratory volume in one second (FEV1), the forced vital capacity (FVC) and the FEV1/FVC ratio before (pre), and after (post), short-acting bronchodilator. The association of HIV infection and ART use with pulmonary function was analysed using linear regression models, adjusting for age, gender, body surface area (BSA), employment, education, smoking and TB.ResultsOverall, 548 participants (62% women) were included with a mean age of 38 (standard deviation [s.d.] 9.5) years. No effect of HIV or ART on post-FEV1 was observed in adjusted analysis. Additional adjustment for TB resulted in a higher post-FEV1 in participants on ART compared with HIV-negative participants, whereas TB was associated with a lower FEV1. No effect of HIV and ART on post-FEV1/FVC was observed.ConclusionHIV infection and ART use were not associated with reduced pulmonary function in this urban African population. Tuberculosis showed a mediating effect on the association between HIV, ART and pulmonary function.

'You Have to Withstand That Because You Have Come for What You Have Come for': Barriers and facilitators to antiretroviral treatment access among older South Africans living with HIV.

Nationwide rollout of antiretroviral treatment (ART) is increasing the number of older persons living with HIV (OPLWH) in South Africa. Yet, little is known about how the sociological aspects of ageing - stigma, finances and family dynamics - impact access to ART. Qualitative interviews with 23 persons aged 50-plus living near Cape Town highlight the barriers and facilitators to the acceptability, affordability and availability of ART access among OPLWH. Key age-related barriers included perceived shame of sexuality and disclosing HIV status to others, perceived disrespect by clinical staff, affording transportation to clinics and pre-existing co-morbidities. Key age-related facilitators included family moral and financial support, particularly from children and grandchildren, and access to social grants. Importantly, many barriers and facilitators had feedback loops, for example social grants reduced transportation barriers to clinics when ageing and poor health limited mobility. As the population living with HIV ages, it is critical to assess the ways ageing, as a social process, impacts ART access and to address these to improve older persons' HIV care.

Did sexual behaviour differences between HIV infection and treatment groups offset the preventative biological effects of ART roll-out in Zimbabwe?

Declines in HIV incidence have been slower than expected during the roll-out of antiretroviral treatment (ART) services in sub-Saharan African populations suffering generalized epidemics. Using data from a population-based, open cohort HIV sero-survey (2004–13), we found evidence for initial reductions in sexual activity and multiple sexual partnerships, followed by increases during the period of ART scale-up in areas of high HIV prevalence in Manicaland, east Zimbabwe. Recent population-level increases in condom use were also recorded, but largely reflected high use by the rapidly growing proportion of HIV-infected individuals on treatment. Sexual risk behaviour increased in susceptible uninfected individuals and in untreated (and therefore more infectious) HIV-infected men, which may have slowed the decline in HIV incidence in this area. Intensified primary HIV prevention programmes, together with strengthened risk screening, referral, and support services following HIV testing, could help to maximize the impact of ‘test-and-treat’ programmes in reducing new infections.

HIV-associated neurocognitive impairment in stable people living with HIV on ART in rural Tanzania.

Few studies have assessed cognitive impairment among healthy people living with HIV (PLWH) who are stable on antiretroviral treatment (ART) in sub-Saharan Africa. We conducted a cross-sectional study among a random sample of stable adult PLWH from rural Tanzania on ART for more than 1year and without immunological failure or pre-existing neurological disease. We evaluated the prevalence and risk factors for neurocognitive impairment (NCI), assessed through neuropsychological tests, functional and depression questionnaires and defined as a mean Z-score≤-1 in two or more cognitive domains. Among 243 participants [median age = 44.3 years (interquartile range: 36-52] and 71% female] we found a rate of NCI of 19.3% (95% confidence interval: 14.8-24.8%). Memory and psychomotor domains demonstrated the highest impairment. Independent predictors of NCI were age and self-reported alcohol use. Other classical risk factors were not associated with HIV-associated NCI. Despite effective ART roll-out, NCI remained a prevalent condition in this healthy rural Tanzanian population of PLWH on ART. Age and alcohol use were key risk factors.

Households in HIV Care: Designing an Intervention to Stimulate HIV Competency in Households in South Africa.

Despite the Universal Test and Treat program and widespread antiretroviral treatment rollout, South Africa is still facing HIV prevention and treatment challenges, which are aggravated by human resource shortages in the healthcare sector. Individual- and community-level responses to these HIV-related challenges are increasingly being explored, for example, in community and home-based care. The role of the household as a crucial mediating social level has, however, largely been omitted. This paper outlines the design of an intervention to stimulate the involvement of the household in support for people living with HIV in South Africa. The 6SQuID model guided the intervention development process in four phases: (1) formative research, theory formulation, and a review of the existing literature, (2) integration of the results from the formative research into the “Positive Communication Process” (P2CP model) as a mechanism of change, (3) design of a community-health-worker-led intervention as the way to deliver the change mechanism, and (4) testing and revision of the developed intervention material—called Sinako—in a small-scale pilot study. The Sinako intervention anticipates that the future of chronic HIV care in resource-constrained settings will need to integrate the patient's household into the fight against HIV.

Transmitted HIV drug resistance among individuals with newly diagnosed HIV infection: a multicenter observational study

Fifteen years after the roll-out of antiretroviral treatment (ART) in China, there is limited information available on transmitted HIV drug resistance (TDR). This study aimed to characterize the epidemiology of TDR in China. We conducted a prospective cross-sectional observational study. We analyzed the demographic, clinical, and virological data of individuals with newly diagnosed HIV infection using data from the Beijing HIV laboratory network collected between 2001 and 2017. We did population-based sequencing of the pol gene on plasma specimens and identified TDR mutations using the WHO list for surveillance of TDR mutations. Data on TDR were available for 91% of the 10 115 individuals with newly diagnosed HIV infection tested, of whom 19.2% were from rural areas. The overall prevalence of TDR was 4.1% [95% confidence interval (CI): 3.7-4.5%], with a declining trend over the period 2001-2017. In the multivariable analysis, the risk of TDR differed significantly according to sex [odds ratio (OR) for women vs. men: 0.41, 95% CI: 0.22-0.69, P = 0.002]; infection type (OR for CRF07_BC vs. CRF01_AE: 0.24, 95% CI: 0.16-0.36, P < 0.001); and sampling period (OR for 2009-2012 vs. 2001-2008: 0.57, 95% CI: 0.41-0.79; P = 0.01), and was significantly higher among individuals from Hebei province than in those from Beijing (OR: 1.43, 95% CI: 1.05-1.96; P = 0.02). In China, the prevalence of TDR among individuals with newly diagnosed HIV infection is relatively low. Trends in TDR should be assessed in other countries with a high TDR burden.

HIV and cardiovascular diseases risk: exploring the interplay between T-cell activation, coagulation, monocyte subsets, and lipid subclass alterations.

Although rollout of combined antiretroviral treatment (cART) has blunted human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) onset, there is increased development of cardiovascular diseases (CVDs) in HIV-infected individuals. While most HIV-infected individuals on cART achieve viral suppression, this may not necessarily result in complete immunological recovery. This study therefore evaluated T-cell-mediated changes and coagulation markers in HIV-positive individuals to ascertain their potential to increase CVD risk. Eighty participants were recruited (Worcester, South Africa), and fasted blood was collected to evaluate: 1) immune activation (CD38 expression on CD4+ and CD8+ T cells) and thrombus formation [tissue factor (CD142)] on CD4+ and CD8+ T cells; 2) monocyte subpopulations (nonclassical, intermediate, and classical); and 3) classical regulatory T (Treg) cells with activation markers [glycoprotein A repetitions predominant (GARP) and special AT-rich sequence-binding protein 1 (SATB-1)]. High- and low-density lipoprotein subclasses (Lipoprint) were also determined. This study revealed four key findings for HIV-positive patients: 1) coexpression of the CD142 coagulation marker together with immune activation on both CD4+ and CD8+ T cells during chronic infection stages; 2) Treg cell activation and upregulated GARP and SATB-1 contributing to Treg dysfunction in chronic HIV; 3) proatherogenic monocyte subset expansion with significant correlation between T-cell activation and macrophage activation (marker: CD163); and 4) significant correlation between immune activation and lipid subclasses, revealing crucial changes that can be missed by traditional lipid marker assessments (LDL and HDL). These data also implicate lipopolysaccharide-binding protein as a crucial link between immune activation, lipid alterations, and increased CVD risk. NEW & NOTEWORTHY With combined antiretroviral treatment rollout, HIV-AIDS patients are increasingly associated with cardiovascular diseases onset. This study demonstrated the significant interplay between adaptive immune cell activation and monocyte/macrophage markers in especially HIV-positive individuals with virological failure and on second line treatment. Our data also show a unique link between immune activation and lipid subclass alterations, revealing important changes that can be missed by traditional lipid marker assessments (e.g., LDL and HDL).

Pesky metrics: the challenges of measuring ART adherence among HIV-positive adolescents in South Africa

ABSTRACTThe global rollout of antiretroviral treatment (ART) for HIV is one of the largest public health interventions ever undertaken. As the rollout expands, a growing body of research has focused on adherence to ART: how is it measured, what are the flaws of these metrics, and how may these be improved? We provide an overview of current, critical developments in adherence research among adolescents, and of how research on adherence to ART among adolescents within hyper-epidemic contexts has challenged definitions and measurements of adherence. We then explore the development of adherence metrics within an interdisciplinary study about HIV-positive adolescents: the Mzantsi Wakho study. Tracing the conceptualisation and adaptation of adherence metrics within this study, we examine how qualitative and quantitative approaches may be combined to establish more comprehensive adherence metrics. Findings highlight the challenges and the imperatives of synthesising numerous methods, data points, and temporalities. They also point to the need for researchers to establish direct and continued participation by adolescents themselves to better conceptualise and measure adherence, as well as other health behaviours.

‘Yummy or crummy?’ The multisensory components of medicines-taking among HIV-positive youth

ABSTRACTThe global rollout of Antiretroviral Treatment (ART) has revealed an urgent need to understand the medicines-taking practices of HIV-positive adolescents. In the last decade, the literature on the social determinants of health has broadened the evidence-base on ART adherence. Interdisciplinary studies have expanded conceptions of medicines-taking beyond clinical or health systems frameworks, recognising the importance of socio-structural conditions and of patients’ beliefs and experiences. Participatory research techniques which foreground the perspectives of adolescents provide greater insights still into their adherence. This article explores the use of participatory methods within a broader study on the social determinants of ART adherence among HIV-positive adolescents in South Africa. We describe how participatory methods were incorporated into this study (n = 1,059 in the quantitative baseline). We focus on an exercise, ‘Yummy or crummy?’, that explored the multisensory dimensions of medicines-taking, including their colour, smell, shape, and delivery mechanism. We describe two principal findings: first, adolescents’ preference for greater understanding of the chemical workings of medicines, manifested in their preferences for colour, taste and shape of medicines; and second, the vital relationship between sensory preferences and the social imperatives of discretion and confidentiality regarding HIV-status.

Change in HIV-related stigma in South Africa between 2004 and 2016: a cross-sectional community study

ABSTRACTA critical component of an AIDS-free generation is to reduce HIV-related stigma. Previous research predicted that stigma would decline over time with increased contact with PLWH, understanding of the disease and availability of treatment. The aim of the research was to explore change in stigma over a 12-year period, by comparing data collected from two large cross-sectional samples from South African communities in 2004 (before the roll-out of antiretroviral treatment (ART)) and in 2016. Students recruited respondents according to criteria related to age, gender, race and area of living. A survey assessing moral judgement and interpersonal distance was used to assess personal and perceived community stigma. Responses to ten identical items used in the 2004 and 2016 data collection were compared. Personal stigma attached to HIV decreased significantly over time, except in respect of having close contact with PLWH, such as dating and befriending. Perceived community stigma remained high in all subgroups. It is argued that perceived community stigma contributes to high levels of internalised stigma among PLWH. Interventions should focus on helping PLWH to cope with perceived stigma and strategies to address stereotyping, which contributes to perceived community stigma.

Assessing the utility of the tipping point ratio to monitor HIV treatment programmes in the era of universal access to ART.

BackgroundThe epidemiological tipping point ratio (TPR) has been suggested as a useful indicator to monitor the scale-up of antiretroviral treatment (ART) programmes and determine when scale-up is sufficient to control the epidemic. TPR has been defined as the ratio of yearly number of new HIV infections to the yearly number of new ART initiations or to the yearly net increase in the number of people on ART. It has been used to rank the progress of treatment programmes across countries, with the objective of reaching a TPR value under 1. Our study aims to assess if TPR alone can be used as an indicator of ART success across settings by comparing the expected changes in HIV incidence and ART coverage when TPR is maintained constant over time. In particular, we focus on the effect of ART initiation timing (emphasis on ART being initiated early or late during HIV progression) on the interpretation of the TPR.MethodsWe used a dynamic model of HIV transmission in South Africa representing ART rollout leading to universal treatment in 2017. The model is calibrated to HIV incidence, HIV prevalence and ART coverage in 2012 in South Africa, and 1000 simulations are selected for the base-case scenario. To measure the effect of TPR, we simulate TPR-preserving interventions, maintaining TPR (yearly number of new ART initiations denominator) at the value observed in 2019 (between 0.65 and 1.25) for 15 years. We compare ART coverage and HIV incidence across TPR values and across strategies in which ART access is prioritized differently. In a secondary analysis, we illustrate the sensitivity of new ART initiations to ART retention, and we compare both definitions of the TPR.ResultsOur analysis shows that HIV incidence reduction is weakly correlated to TPR: the same reduction in HIV incidence (15%) can be achieved by implementing the same strategy with a wide range of TPR maintained (0.65–1.12). Assuming high retention in ART, TPR-preserving strategies prioritizing early ART initiation yield greater reduction in HIV incidence than strategies where most individuals initiate ART late. High ART coverage is associated with low HIV incidence and it can be reached with a TPR below or equal to one with strategies favoring early ART initiation. Low ART retention over time results in higher HIV incidence even if TPR is maintained low. If ART retention is low, strategies prioritizing late ART initiation are associated with lower HIV incidence than strategies where ART is initiated early. Maintaining a fixed TPR value based on the net increase in people on ART gives higher HIV incidence reduction and requires fast ART scale-up.ConclusionOur analysis suggests that the TPR is not an adequate indicator of ART programme impact, without information on ART coverage and retention. Achieving early initiation and adherence to treatment to improve ART coverage might be as important as attaining a specific TPR target. Comparisons of TPR in different settings should account for differences in epidemic conditions.

Estimating the impact of antiretroviral treatment on adult mortality trends in South Africa: A mathematical modelling study.

BackgroundSubstantial reductions in adult mortality have been observed in South Africa since the mid-2000s, but there has been no formal evaluation of how much of this decline is attributable to the scale-up of antiretroviral treatment (ART), as previous models have not been calibrated to vital registration data. We developed a deterministic mathematical model to simulate the mortality trends that would have been expected in the absence of ART, and with earlier introduction of ART.Methods and findingsModel estimates of mortality rates in ART patients were obtained from the International Epidemiology Databases to Evaluate AIDS–Southern Africa (IeDEA-SA) collaboration. The model was calibrated to HIV prevalence data (1997–2013) and mortality data from the South African vital registration system (1997–2014), using a Bayesian approach. In the 1985–2014 period, 2.70 million adult HIV-related deaths occurred in South Africa. Adult HIV deaths peaked at 231,000 per annum in 2006 and declined to 95,000 in 2014, a reduction of 74.7% (95% CI: 73.3%–76.1%) compared to the scenario without ART. However, HIV mortality in 2014 was estimated to be 69% (95% CI: 46%–97%) higher in 2014 (161,000) if the model was calibrated only to HIV prevalence data. In the 2000–2014 period, the South African ART programme is estimated to have reduced the cumulative number of HIV deaths in adults by 1.72 million (95% CI: 1.58 million–1.84 million) and to have saved 6.15 million life years in adults (95% CI: 5.52 million–6.69 million). This compares with a potential saving of 8.80 million (95% CI: 7.90 million–9.59 million) life years that might have been achieved if South Africa had moved swiftly to implement WHO guidelines (2004–2013) and had achieved high levels of ART uptake in HIV-diagnosed individuals from 2004 onwards. The model is limited by its reliance on all-cause mortality data, given the lack of reliable cause-of-death reporting, and also does not allow for changes over time in tuberculosis control programmes and ART effectiveness.ConclusionsART has had a dramatic impact on adult mortality in South Africa, but delays in the rollout of ART, especially in the early stages of the ART programme, have contributed to substantial loss of life. This is the first study to our knowledge to calibrate a model of ART impact to population-level recorded death data in Africa; models that are not calibrated to population-level death data may overestimate HIV-related mortality.

Exploring the health status of older persons in Sub-Saharan Africa.

Sub-Saharan Africa (SSA) has traditionally had a low life expectancy due to the onslaught of the HIV epidemic, high levels of chronic diseases, injuries, conflict and undernutrition. Therefore, research into public health concerns of older persons has largely been overlooked. With a growing population, the roll-out of antiretroviral treatment, and the effects of globalisation, SSA is experiencing an increase in the number of people over 50 years of age as well as an increase in the prevalence of non-communicable diseases (NCD). The aim of this review is to highlight available research on the health status of older persons in SSA, and to identify the current gaps that warrant further investigation. A literature search was conducted across multiple databases to identify studies in SSA on older persons (aged 50 years and older) related to health indicators including nutritional status, NCD and HIV burden. While it was concluded that older persons are at an increased risk of poor health, it was also determined that significant gaps exist in this particular area of research; namely nutrient deficiency prevalence. Resources should be directed towards identifying the health concerns of older persons and developing appropriate interventions.

The effects of HIV on fertility by infection duration: evidence from African population cohorts before antiretroviral treatment availability.

To estimate the relationship between HIV natural history and fertility by duration of infection in east and southern Africa before the availability of antiretroviral therapy and assess potential biases in estimates of age-specific subfertility when using retrospective birth histories in cross-sectional studies. Pooled analysis of prospective population-based HIV cohort studies in Masaka (Uganda), Kisesa (Tanzania) and Manicaland (Zimbabwe). Women aged 15-49 years who had ever tested for HIV were included. Analyses were censored at antiretroviral treatment roll-out. Fertility rate ratios were calculated to see the relationship of duration of HIV infection on fertility, adjusting for background characteristics. Survivorship and misclassification biases on age-specific subfertility estimates from cross-sectional surveys were estimated by reclassifying person-time from the cohort data to simulate cross-sectional surveys and comparing fertility rate ratios with true cohort results. HIV-negative and HIV-positive women contributed 15 440 births and 86 320 person-years; and 1236 births and 11 240 000 person-years, respectively, to the final dataset. Adjusting for age, study site and calendar year, each additional year since HIV seroconversion was associated with a 0.02 (95% confidence interval 0.01-0.03) relative decrease in fertility for HIV-positive women. Survivorship and misclassification biases in simulated retrospective birth histories resulted in modest underestimates of subfertility by 2-5% for age groups 20-39 years. Longer duration of infection is associated with greater relative fertility reduction for HIV-positive women. This should be considered when creating estimates for HIV prevalence among pregnant women and prevention of mother-to-child transmission need over the course of the HIV epidemic and antiretroviral treatment scale up.

Conceptualising the Factors Affecting Retention in Care of Patients on Antiretroviral Treatment in Kabwe District, Zambia, Using the Ecological Framework.

Background HIV remains a major public health challenge in Zambia. The roll-out of antiretroviral treatment (ART) has engendered new challenges in retention in care. Objective To conceptualise the factors affecting retention in care of ART patients at three primary healthcare facilities using the ecological framework. Method Qualitative data were collected through in-depth interviews with 45 ART patients and three focus group discussions with 20 healthcare providers from three primary healthcare facilities in Kabwe district, Zambia, and subjected to thematic content analysis. Results Individual level barriers to retention in care included side effects, gaining weight, belief in faith healing, and use of herbal remedies and alcohol. Interpersonal barriers such as stigma and nondisclosure of HIV status were reported. At the institutional level, inadequate space in the clinic, long waiting times, long travel distances, and shortage of third-line drugs presented barriers to retention in care. Food shortages and patient mobility were reported as community barriers to retention in care. Conclusion The ecological framework conceptualises the complex and dynamic factors affecting retention in ART care and highlights the need for multifaceted interventions that combine health education, disease management, and opportunities for income generation in a socially responsive and accountable environment.

Marriage, violence and HIV: the shifting policy context in Uganda

The policy environment for vulnerable women in Uganda is rapidly changing, with the aim of introducing more punitive measures for violent offenders and more options for women seeking help. This paper examines HIV-positive women who experienced intimate partner violence in two regions of Uganda prior to the enactment of the Domestic Violence Act of 2010. Based on in-depth interviews and observations, it reports on women’s views of marriage and relationships, and their strategies for help seeking to show the interaction between the two phenomena within the local cultural and political context. HIV-positive women in Uganda reshape their notions of marriage and love based on experiences of violence, illness management and broader social factors. Their narratives of relationships and conflict reveal an ambivalence toward formal marriage because of both its security and rights and its potential to inhibit leaving, as well as a reluctance to seek help through formal means. This construction of marriage is intertwined with the shifting social backdrop in Uganda, in particular the increasing rollout of antiretroviral treatment for HIV and the development of new policies surrounding violence, marriage and divorce. Women’s experiences show potential points of intervention and the need for multi-sectoral responses to violence.

'Deep down in their heart, they wish they could be given some incentives': a qualitative study on the changing roles and relations of care among home-based caregivers in Zambia.

BackgroundAcross Sub-Saharan Africa, the roll-out of antiretroviral treatment (ART) has contributed to shifting HIV care towards the management of a chronic health condition. While the balance of professional and lay tasks in HIV caregiving has been significantly altered due to changing skills requirements and task-shifting initiatives, little attention has been given to the effects of these changes on health workers’ motivation and existing care relations.MethodsThis paper draws on a cross-sectional, qualitative study that explored changes in home-based care (HBC) in the light of widespread ART rollout in the Lusaka and Kabwe districts of Zambia. Methods included observation of HBC daily activities, key informant interviews with programme staff from three local HBC organisations (n = 17) and ART clinic staff (n = 8), as well as in-depth interviews with home-based caregivers (n = 48) and HBC clients (n = 31).ResultsSince the roll-out of ART, home-based caregivers spend less time on hands-on physical care and support in the household, and are increasingly involved in specialised tasks supporting their clients’ access and adherence to ART. Despite their pride in gaining technical care skills, caregivers lament their lack of formal recognition through training, remuneration or mobility within the health system. Care relations within homes have also been altered as caregivers’ newly acquired functions of monitoring their clients while on ART are met with some ambivalence. Caregivers are under pressure to meet clients and their families’ demands, although they are no longer able to provide material support formerly associated with donor funding for HBC.ConclusionsAs their responsibilities and working environments are rapidly evolving, caregivers’ motivations are changing. It is essential to identify and address the growing tensions between an idealized rhetoric of altruistic volunteerism in home-based care, and the realities of lay worker deployment in HIV care interventions that not only shift tasks, but transform social and professional relations in ways that may profoundly influence caregivers’ motivation and quality of care.

Reducing the overall HIV-burden in South Africa: is ‘reviving ABC’ an appropriate fit for a complex, adaptive epidemiological HIV landscape?

This article questions the recommendations to ‘revive ABC (abstain, be faithful, condomise)’ as a mechanism to ‘educate’ people in South Africa about HIV prevention as the South African National HIV Prevalence, Incidence and Behaviour Survey, 2012, suggests. We argue that ABC was designed as a response to a particular context which has now radically changed. In South Africa the contemporary context reflects the mass roll-out of antiretroviral treatment; significant bio-medical knowledge gains; a generalised population affected by HIV that has made sense of and embodied those diverse experiences; and a government committed to confronting the epidemic. We suggest that the situation can now be plausibly conceptualised as a complex, adaptive epidemiological landscape that could benefit from an expansion of the existing, ‘descriptive’ prevention paradigm towards strategies that focus on the dynamics of transmission. We argue for this shift by proposing a theoretical framework based on complexity theory and pattern management. We interrogate one educational prevention heuristic that emphasises the importance of risk-reduction through the lens of transmission, called A-3B-4C-T. We argue that this type of approach provides expansive opportunities for people to engage with the epidemic in contextualised, innovative ways that supersede the opportunities afforded by ABC. We then suggest that framing the prevention imperative through the lens of ‘dynamic prevention’ at scale opens more immediate opportunities, as well as developing a future-oriented mind-set, than the ‘descriptive prevention’ parameters can facilitate. The parameters of the ‘descriptive prevention’ paradigm, that maintain — and partially reinforce — the presence of ABC, do not have the flexibility required to develop the armamentarium of tools required to contribute to the management of a complex epidemiological landscape. Uncritically adhering to both the ‘descriptive paradigm’, and ABC, represents an historically dislocated form of prevention — with restrictive options for reducing the overall burden of HIV-related challenges in South Africa.
