Life expectancies of South African adults starting antiretroviral treatment: collaborative analysis of cohort studies

Association among therapeutic adherence, health literacy, and engagement in care: How to increase health-conscious management of HIV disease

BACKGROUND

In the context of People Living with HIV (PLWH), poor health literacy (HL) seems to be linked to poorer health outcomes and reduced engagement in care. Additionally, the level of HL can affect HIV knowledge and may impact adherence to antiretroviral therapy (ART). This research explored the connection between ART adherence, HL, and engagement in care in a cohort of 250 PLWH receiving ART in Italy.

METHODS

A questionnaire was given to PLWH at Policlinico Gemelli in Rome to assess their health literacy and adherence to therapy. The Brief Health Literacy Screening (BHLS) and the Newest Vital Sign (NVS) were used to evaluate subjective and objective HL. Adherence levels were self-reported as poor, good, or excellent, and the assessment included the Patient Health Engagement Scale (PHE-S).

RESULTS

Notably, the majority of the sample comprised male individuals (67.9%), with 69.2% reporting a 10-years or longer duration between their HIV diagnosis and their initiation of ART. It was found that PLWH with poor adherence had low schooling, had been living with HIV for 1-5 years, were HCV co-infected, had a viremia >50 copies/mL, poor health status, poor engagement in care, and poor HL (p = <0.001). They exhibited lower mean scores on the subjective HL scale and lower CD4 T-cell counts and nadir CD4 T-cell counts (p < .001).

CONCLUSION

Our study demonstrated a positive correlation between higher HL levels and improved disease management, treatment adherence, and overall physical and mental well-being. Enhanced HL capabilities are paramount in bolstering health management and treatment adherence.

Including the Household: Individual, Community and Household Factors Affecting Antiretroviral Therapy Adherence After ART Initiation in Cape Town, South Africa

Antiretroviral therapy (ART) adherence is crucial for health outcomes of people living with HIV (PLHIV), influenced by a complex interplay of individual, community, and household factors. This article focuses on the influence of household factors, as well as individual and community factors, on ART adherence among PLHIV in Cape Town who have recently initiated ART. Baseline data for a cluster-randomized controlled trial were collected from 316 PLHIV in 12 districts in Cape Town between 6th May 2021 and 22nd May 2022. Zero-inflated Poisson models, with cluster-adjusted standard errors, were used to analyse the association between individual, household, and community factors and ART adherence measures. At the household-level, household support was associated with both better self-rated adherence (exp(β) = 0.81, z =  - 4.68, p < 0.001) and fewer days when pills were missed (exp(β) = 0.65, z =  - 2.92, p = 0.003). Psychological violence (exp(β) = 1.37, z = 1.97, p = 0.05) and higher household asset scores (exp(β) = 1.29, z =  - 2.83, p = 0.05) were weakly associated with poorer ART adherence. At the individual-level, male gender (exp(β) = 1.37, z = 3.95, p < 0.001) and reinitiating ART (exp(β) = 1.35, z = 3.64, p < 0.001) were associated with worse self-rated ART adherence; higher education levels (exp(β) = 0.30 times, z =  - 3.75, p < 0.001) and better HIV knowledge (exp(β) = 0.28, z =  - 2.83, p = 0.005) were associated with fewer days where pills were missed. At the community-level, community stigma was associated with worse self-rated ART adherence (exp(β) = 1.24, z = 3.01, p = 0.003). When designing interventions to improve ART adherence, household, individual and community factors should all be considered, particularly in addressing gender-based disparities, reducing stigma, tackling violence, and enhancing household support.Clinical Trial Number: Pan African Clinical Trial Registry, PACTR201906476052236.

The cost of adding rapid screening for diabetes, hypertension, and COVID-19 to COVID-19 vaccination queues in Johannesburg, South Africa

BACKGROUND

Non-communicable diseases (NCDs) are responsible for 51% of total mortality in South Africa, with a rising burden of hypertension (HTN) and diabetes mellitus (DM). Incorporating NCDs and COVID-19 screening into mass activities such as COVID-19 vaccination programs could offer significant long-term benefits for early detection interventions. However, there is limited knowledge of the associated costs and resources required. We evaluated the cost of integrating NCD screening and COVID-19 antigen rapid diagnostic testing (Ag-RDT) into a COVID-19 vaccination program.

METHODS

We conducted a prospective cost analysis at three public sector primary healthcare clinics and one academic hospital in Johannesburg, South Africa, conducting vaccinations. Participants were assessed for eligibility and recruited during May-Dec 2022. Costs were estimated from the provider perspective using a bottom-up micro-costing approach and reported in 2022 USD.

RESULTS

Of the 1,376 enrolled participants, 240 opted in to undergo a COVID-19 Ag-RDT, and none tested positive for COVID-19. 138 (10.1%) had elevated blood pressure, with 96 (70%) having no prior HTN diagnosis. 22 (1.6%) were screen-positive for DM, with 12 (55%) having no prior diagnosis. The median cost per person screened for NCDs was $1.70 (IQR: $1.38-$2.49), respectively. The average provider cost per person found to have elevated blood glucose levels and blood pressure was $157.99 and $25.19, respectively. Finding a potentially new case of DM and HTN was $289.65 and $36.21, respectively. For DM and DM + HTN screen-positive participants, diagnostic tests were the main cost driver, while staff costs were the main cost driver for DM- and HTN screen-negative and HTN screen-positive participants. The median cost per Ag-RDT was $5.95 (IQR: $5.55-$6.25), with costs driven mainly by test kit costs.

CONCLUSIONS

We show the cost of finding potentially new cases of DM and HTN in a vaccine queue, which is an essential first step in understanding the feasibility and resource requirements for such initiatives. However, there is a need for comparative economic analyses that include linkage to care and retention data to fully understand this cost and determine whether opportunistic screening should be added to general mass health activities.

Evaluating the spatial accessibility and spatial layout optimization of HIV/AIDS healthcare services in Shandong Province, China

Improving access to HIV/AIDS healthcare services is of great concern to government and policymakers striving to strengthen overall public health. How to reasonably allocate HIV/AIDS healthcare resources and maximize the equality of access to healthcare services across subdistrict areas has become an urgent problem to be solved. However, there is limited research on this topic in China. It is necessary to evaluate spatial accessibility to improve the accessibility and equity of HIV/AIDS healthcare services. In this study, the improved multi-modal two-step floating catchment area (2SFCA) and inverted 2SFCA (i2SFCA) methods are used to measure the spatial accessibility of HIV/AIDS healthcare services and the crowdedness of the healthcare sites in Shandong Province, China. Then, the theoretical supply and the optimal spatial distribution of resources are calculated and visualized by minimizing the accessibility gaps between demand locations. This study showed that the spatial accessibility of HIV/AIDS service resources in Shandong Province was concentrated and unevenly distributed, and the accessibility scores in the marginal areas of prefecture-level cities were significantly lower than those in other areas. Regions with a large number of doctors had significantly higher levels of spatial accessibility. The ART accessibility scores in the southwest of Shandong Province were higher than those in other regions. As the travel friction coefficient increased, the accessibility scores formed an approximately circular cluster distribution centered on the healthcare sites in geographical distribution. More ART drugs needed to be supplied in marginal areas and more doctors were needed to work on HIV/AIDS in urban areas to address the spatial distribution imbalance of HIV/AIDS healthcare services. This study profoundly analyzed the spatial accessibility of HIV/AIDS healthcare services and provided essential references for decision-makers. In addition, it gives a significant exploration for achieving the goal of equal access to HIV/AIDS healthcare services in the future.

'Remember there is that thing called confidentiality': experiences of institutional discrimination in the health system among adolescent boys and young men living with HIV in the Eastern Cape province of South Africa

Adolescents and men are two populations that perform poorly within the HIV cascade of care, having worse AIDS-related health outcomes, and experiencing higher levels of HIV-related stigma. This paper explores institutional health system discrimination as experienced by adolescent boys with perinatally-acquired HIV, situating them within the social and gendered contexts of the Eastern Cape Province, South Africa. Life history narratives (n = 36) and in-depth semi-structured interviews (n = 32) with adolescent boys living with HIV aged 13-22 were conducted in 2017-2018. In-depth semi-structured interviews with biomedical and traditional health practitioners (n = 14), analysis of health facility files (n = 41) and clinic observations were also conducted. Together, triangulated sources point to an incongruence between the complex needs of adoelscent boys and young men living with HIV and their experiences within the health system. Two institutional discrimination-related deterrents to retention in care were identified: (1) lack of confidentiality due to health facility layouts and practices that visibilised people living with HIV; and (2) mistreatment in the form of shouting. This article contributes to the limited literature on the experiences of young men within the HIV continuum of care, focusing on how stigma influences how young men experience and engage with the health sector.

Improving linkage to HIV care following a reactive HIV self-testing result among men in KwaZulu-Natal, South Africa

BACKGROUND

Despite the many interventions that have been implemented in sub-Saharan Africa to improve the uptake of HIV testing and antiretroviral (ART) initiation services, the rates at which men are tested for HIV and initiated on ART have remained consistently lower compared to those for women. We aim to investigate barriers and facilitators for linkage to care following HIVST positive results among men aged between 18 and 49 years, and use these findings to design an intervention to improve linkage to care among men in a high-HIV prevalent district in KwaZulu-Natal province, South Africa.

METHODS

This multi-method study will be conducted over 24 months in eight purposively selected HIV testing and treatment facilities from December 2023 to November 2025. For the quantitative component, a sample of 197 HIV positive men aged 18-49 years old who link to care after HIV self-test (HIVST) will be recruited into the study. HIVST kits will be distributed to a minimum of 3000 men attending community services through mobile clinics that are supported by the Health Systems Trust, at different service delivery points, including schools, taxi ranks and other hotspots. The qualitative component will consist of in-depth interviews (IDIs) with 15 HIVST users and IDIs with 15 key informants. To design and develop acceptable, feasible, effective, and sustainable models for improving linkage to care, three groups of HIVST users (2*positive (N = 12) and 1*negative (N = 12)) will be purposively select to participate in a design workshop. Chi square tests will be used to identify social and demographic factors associated with linkage, while logistic regression will be used to identify independent factors. Kaplan Meier curves and cox proportional hazard models will be used to identify factors associated with time to event. Content and thematic approaches will be used to analyze the qualitative data.

DISCUSSION

There remains an urgent need for designing and implementing innovative intervention strategies that are convenient and tailored for addressing the needs of men for improving HIV testing and linkage to care at early stages in resource-limited settings, to improve individual health outcomes, reduce transmission from HIV and minimize HIV-related mortality rates. Our proposed study offers several important innovations aimed at improving linkage to care among men. Our study targets men, as they lag the HIV continuum but are also under-researched in public health studies.

Psychometric and Circumplex Properties Evaluation of the International Personality Item Pool-Interpersonal Circumplex (IPIP-IPC) in Chinese People Living with HIV (PLWH)

Background and Purpose

With the improved life expectancy of people living with HIV (PLWH) due to widespread use of antiretroviral therapy (ART), there is a greater emphasis on enhancing long-term well-being and overall quality of life for PLWH. Understanding interpersonal personalities of PLWH can gain further insight into how to improve the overall quality of life in this population. The International Personality Item Pool-Interpersonal Circumplex (IPIP-IPC) scale has been developed to assess interpersonal personalities of individuals, and this scale has been translated into Chinese. However, the Chinese version of IPIP-IPC has not been tested among PLWH in China. In this study, we aimed to test the psychometric properties and circumplex structure of this scale.

Methods

This study was based on cross-sectional, multi-center, large sample data. We employed the Chinese version of IPIP-IPC scale on 3040 PLWH from April 2022 to April 2023 in China to test its psychometric as well as circumplex properties. The structural summary method (SSM) was employed to analyze the circumplex structure of the scale.

Results

The total scale exhibited a Cronbach's alpha of 0.85 and McDonald's omega of 0.91. Out of the 288 possible relationships, 275 relationships satisfy the circular properties hypothesis. The scale demonstrates good reliability and validity, meeting the requirements of psychometrics.

Conclusion

Our findings demonstrate that the Chinese version of the IPIP-IPC scale is a reliable tool for evaluating interpersonal personalities in this population. These results highlight the validity and applicability of the IPIP-IPC scale specifically in the Chinese context, providing valuable insights into the intricacies of interpersonal traits among PLWH.

The impact of geriatric syndromes on quality of life among older people living with HIV in Kampala, Uganda

Objective

Older people living with HIV (OPWH) often have lower quality of life (QoL) compared to general population. Measuring their QoL is an important step in HIV care to ensure they have long healthy lives. This study aimed to evaluate the quality of life and its associated factors among people living with HIV aged 60 years and above in Uganda.

Methods

We used a cross-sectional analysis of older people living with HIV (OPWH) enrolled in a prospective cohort from December 2020 - December 2021. Quality of life was assessed using the World Health Organisation QoL OLD instrument (WHOQOL-OLD). Linear regression model was used to determine associated factors.

Results

Of the 500 participants enrolled, 51.2% were men and their median age was 64 years (IQR: 62 - 68). WHOQOL-OLD mean score (SD) was 90.1 (8.3) out of 120. Factors that increased overall QoL were (Coefficient [95% Confidence Interval]): being male 2.35 (1.21 - 3.73), having an income of ≥$1 1.30 (-0.16 - 2.76) and paradoxically having more than 2 non-communicable diseases 0.69 (-0.76 - 2.14) in the past, present and future domain of QoL. Those that decreased QoL in the overall and various domains included: an increasing number of geriatric syndromes, depression, pre-frailty, frailty, malnutrition, and low physical function.

Conclusion

Our findings suggest that financial stability contributed to good QoL while geriatric syndromes decreased QoL for OPWH. Integrating the screening and management of geriatric syndromes into HIV care has the potential to improve the overall QoL of OPWH.

Validation of the Global Leadership Initiative on Malnutrition criteria for diagnosis of malnutrition and mortality prediction for people living with HIV or AIDS

OBJECTIVES

To validate the Global Leadership Initiative on Malnutrition (GLIM) criteria to diagnose malnutrition in hospitalized people living with HIV or AIDS (HA) considering different combinations, using the Subjective Global Assessment (SGA) as the semi-gold standard, and to assess the predictive effects of malnutrition according to the GLIM criteria on hospital length of stay and mortality.

METHODS

Retrospective observational study including hospitalized people living with HA aged >18 y. Forty GLIM combinations were obtained by combining the different phenotypic and etiologic criteria. The concurrent validity was assessed according to the sensitivity and specificity values, and the agreement with the SGA was tested using κ values. Multivariate logistic and Cox regression models were used to test the independent predictors for longer length of stay (LOS) and mortality, respectively.

RESULTS

The sample comprised 320 patients (mean age, 44.6 ± 12.1 y; 69.1% were men, and 68.4% were malnourished, according to the SGA). The prevalence of malnutrition, according to GLIM, varied from 10.3% to 69.1%. The combination of any phenotypic criteria with the etiologic criteria of low food intake and the combination of any phenotypic criteria with the etiologic criteria of disease severity were independent predictors for mortality (Hazard Ratio: 2.09 [95% CI, 1.15-3.77] and 2.09 [95% CI, 1.25-3.51], respectively). The combination of low body mass index and reduced absorption was independently associated with LOS higher than the median value (Oodds Ratio; 2.57; 95% CI, 1.21-5.45).

CONCLUSIONS

Nine GLIM combinations had satisfactory sensitivity and specificity values to determine concurrent validity, all of them including weight loss and low weight; two combinations were independent predictors of mortality (any phenotypic criteria and low food intake or opportunistic infections), and one combination predicted longer LOS. Combining any phenotypic criteria with low food intake resulted in adequate concurrent and predictive validity.

Barriers and facilitators for interventions to improve ART adherence in Sub-Saharan African countries: A systematic review and meta-analysis

BACKGROUND

The HIV/AIDS pandemic remains a significant public health issue, with sub-Saharan Africa (SSA) at its epicentre. Although antiretroviral therapy (ART) has been introduced to decrease new infections and deaths, SSA reports the highest incidence of HIV/AIDS, constituting two-thirds of the global new infections. This review aimed to elucidate the predominant barriers and facilitators influencing ART adherence and to identify effective strategies to enhance ART adherence across SSA.

METHODS

A comprehensive review was conducted on studies examining barriers to ART adherence and interventions to boost adherence among HIV-positive adults aged 15 and above in SSA, published from January 2010 onwards. The research utilized databases like Medline Ovid, CINAHL, Embase, and Scopus. Included were experimental and quasi-experimental studies, randomized and non-randomized controlled trials, comparative before and after studies, and observational studies such as cross-sectional, cohort, prospective and retrospective studies. Two independent reviewers screened the articles, extracted pertinent data, and evaluated the studies' methodological integrity using Joanna Briggs Institute's standardized appraisal tools. The compiled data underwent both meta-analysis and narrative synthesis.

RESULTS

From an initial pool of 12,538 papers, 45 were selected (30 for narrative synthesis and 15 for meta-analysis). The identified barriers and facilitators to ART adherence were categorized into seven principal factors: patient-related, health system-related, medication-related, stigma, poor mental health, socioeconomic and socio-cultural-related factors. Noteworthy interventions enhancing ART adherence encompassed counselling, incentives, mobile phone short message service (SMS), peer delivered behavioural intervention, community ART delivery intervention, electronic adherence service monitoring device, lay health worker lead group intervention and food assistance. The meta-analysis revealed a statistically significant difference in ART adherence between the intervention and control groups (pooled OR = 1.56, 95%CI:1.35-1.80, p = <0.01), with evidence of low none statistically significant heterogeneity between studies (I2 = 0%, p = 0.49).

CONCLUSION

ART adherence in SSA is influenced by seven key factors. Multiple interventions, either standalone or combined, have shown effectiveness in enhancing ART adherence. To optimize ART's impact and mitigate HIV's prevalence in SSA, stakeholders must consider these barriers, facilitators, and interventions when formulating policies or treatment modalities. For sustained positive ART outcomes, future research should target specific underrepresented groups like HIV-infected children, adolescents, and pregnant women in SSA to further delve into the barriers, facilitators and interventions promoting ART adherence.

"I was scared dating… who would take me with my status?"-Living with HIV in the era of UTT and U = U: A qualitative study in Johannesburg, South Africa

South Africa rolled out Universal Test-and-Treat (UTT) in 2016, extending treatment eligibility to all persons living with HIV (PLHIV). We sought to understand how PLHIV in Johannesburg, South Africa, interpret and experience their HIV status, five years into the UTT era. In May 2021, we conducted in-depth interviews (IDI) (N = 27) with adult (≥18 years) PLHIV referred by HIV counsellors at three peri-urban primary healthcare clinics. We also conducted three focus group discussions (FGDs) (N = 27) with adult PLHIV recruited from clinics or from civil society organisations through snowball sampling. Follow-up interviews were conducted with 29 IDI and FGD participants. Participants were asked to reflect on their HIV diagnosis, what their HIV status meant to them and how, if at all, being HIV-positive affected their lives. Interviews and focus group discussions were audio-recorded, transcribed, translated to English, and analysed using a grounded theory approach. Participants perceived that HIV was common, that PLHIV could live a normal life with antiretroviral therapy (ART), and that ART was widely accessible. However, HIV elicited feelings of guilt and shame as a sexually transmitted disease. Participants used the language of "blame" in discussing HIV transmission, citing their own reckless behaviour or blaming their partner for infecting them. Participants feared transmitting HIV to others and felt responsible for avoiding transmission. To manage transmission anxiety, participants avoided sexual relationships, chose HIV-positive partners, and/or insisted on using condoms. Many participants feared-or had previously experienced-rejection by partners due to their HIV status and reported hiding their medication, avoiding disclosure, or avoiding relationships altogether. Most participants were not aware that undetectable HIV is untransmittable (U = U). Participants who were aware of U = U expressed less anxiety about transmitting HIV to others and greater confidence in having relationships. Despite perceiving HIV as a manageable chronic condition, PLHIV still faced transmission anxiety and fears of rejection by their partners. Disseminating information on U = U could reduce the psychosocial burdens of living with HIV, encourage open communication with partners, and remove barriers to HIV testing and treatment adherence.

The cost of adding rapid screening for diabetes, hypertension, and COVID-19 to COVID-19 vaccination queues in Johannesburg, South Africa

Background

Non-communicable diseases (NCDs) are responsible for 51% of total mortality in South Africa, with a rising burden of hypertension (HTN) and diabetes mellitus (DM). Incorporating NCD and COVID-19 screening into mass activities such as COVID-19 vaccination programs could offer significant long-term benefits for early detection interventions. However, there is limited knowledge of the associated costs and resources required. We evaluated the cost of integrating NCD screening and COVID-19 antigen rapid diagnostic testing (Ag-RDT) into a COVID-19 vaccination program.

Methods

We conducted a prospective cost analysis at three public sector primary healthcare clinics and one academic hospital in Johannesburg, South Africa, conducting vaccinations. Participants were assessed for eligibility and recruited during May-Dec 2022. Costs were estimated from the provider perspective using a bottom-up micro-costing approach and reported in 2022 USD.

Results

Of the 1,376 enrolled participants, 240 opted in to undergo a COVID-19 Ag-RDT, and none tested positive for COVID-19. 138 (10.1%) had elevated blood pressure, with 96 (70%) having no prior HTN diagnosis. 22 (1.6%) were screen-positive for DM, with 12 (55%) having no prior diagnosis. The mean and median costs per person screened for NCDs were $2.53 (SD: 3.62) and $1.70 (IQR: $1.38-$2.49), respectively. The average provider cost per person found to have elevated blood glucose levels and blood pressure was $157.99 and $25.19, respectively. Finding a new case of DM and HTN was $289.65 and $36.21, respectively. For DM and DM + HTN screen-positive participants, diagnostic tests were the main cost driver, while staff costs were the main cost driver for - and HTN screen-positive and screen-negative participants. The mean and median cost per Ag-RDT was $6.13 (SD: 0.87) and $5.95 (IQR: $5.55-$6.25), with costs driven mainly by test kit costs.

Conclusions

We show the cost of finding new cases of DM and HTN in a vaccine queue, which is an essential first step in understanding the feasibility and resource requirements for such initiatives. However, there is a need for comparative economic analyses that include linkage to care and retention data to fully understand this cost and determine whether opportunistic screening should be added to general mass health activities.

The benefits of care: treated HIV infection and health-related quality of life among older-aged people in Uganda

OBJECTIVES

The objective of this study is to explore how HIV care affects health-related quality of life (HRQoL) among older people in Uganda.

METHODS

We enrolled older-aged (≥49 years) people with HIV receiving HIV care and treatment, along with age- and sex-similar people without HIV. We measured health-related quality of life using the EQ-5D-3L scale.

RESULTS

People with HIV (n = 298) and people without HIV (n = 302) were similar in median age (58.4 vs. 58.5 years), gender, and number of comorbidities. People with HIV had higher self-reported health status (b = 7.0; 95% confidence interval [CI], 4.2-9.7), higher EQ-5D utility index (b = 0.05; 95% CI, 0.02-0.07), and were more likely to report no problems with self-care (adjusted odds ratio [AOR], 2.0; 95% CI, 1.2-3.3) or pain/discomfort (AOR = 1.8, 95% CI, 1.3-2.8). Relationships between HIV serostatus and health-related quality of life differed by gender, but not age.

CONCLUSIONS

Older people with HIV receiving care and treatment reported higher health-related quality of life than people without HIV in Uganda. Access to primary care through HIV programs and/or social network mobilization may explain this difference, but further research is needed to elucidate the mechanisms.

Effect of the Friendship Bench Intervention on Antiretroviral Therapy Outcomes and Mental Health Symptoms in Rural Zimbabwe: A Cluster Randomized Trial

Importance

Common mental disorders (CMD), which include depression and anxiety, are prevalent among people living with HIV and are associated with suboptimal antiretroviral therapy (ART) adherence.

Objective

To assess the effect of a lay health worker-led psychological intervention on ART adherence, virologic suppression, and mental health symptoms.

Design, Setting, and Participants

Open-label pragmatic cluster trial with 1:1 block randomization of 16 health facilities in rural Bikita, Zimbabwe. Recruitment occurred from October 2018 to December 2019, and participants were followed up for 12 months, ending in December 2020. Participants were adults aged 18 years and older, who spoke English or Shona, screened positive for CMD (Shona Symptoms Questionnaire [SSQ]-14 score ≥9), received first-line ART for 6 or more months, had no World Health Organization stage 4 disease, no psychosis, were not pregnant, and provided informed consent. Data were analyzed from March 2021 to February 2022.

Intervention

The Friendship Bench, consisting of 6 lay health worker-led weekly problem-solving therapy sessions and optional peer-led group support.

Main Outcomes and Measures

The primary outcome was mean adherence during 2 to 6 months of follow-up, and the secondary outcomes were mean adherence during 1 to 12 months of follow-up, change in SSQ-14 and Patient Health Questionnaire (PHQ-9) scores (3, 6, 9, and 12 months), and viral load suppression (6 and 12 months).

Results

A total of 516 participants were recruited (244 in Friendship Bench and 272 in enhanced standard care facilities); 438 (84.9%) were female and the mean (SD) age was 45.6 (10.9) years. Mean (SD) adherence between 2 to 6 months was 89.9% (18.4%) in the Friendship Bench group and 87.2% (20.1%) in the control group. The intervention had no statistically significant effect on adherence between 2 to 6 months (unadjusted mean difference, 1.93 percentage points; 95% CI, -1.20 to 5.06 percentage points; P = .23), between months 1 to 12 (mean difference 0.79 percentage points; 95% CI, -2.14 to 3.71 percentage points; P = .60), or viral suppression. Declines in SSQ-14 scores from baseline to 3 months (difference, -1.65; 95% CI, -3.07 to -0.24), 6 months (difference, -1.57; 95% CI, -2.98 to -0.15), and 9 months (difference, -1.63; 95% CI, -3.05 to -0.22) were greater in the Friendship Bench than the standard care group (P < .05). There were no differences in the decline in the SSQ-14 scores from baseline to 12 months and in declines in PHQ-9 scores from baseline to 3, 6, 9, and 12 months.

Conclusions and Relevance

In this randomized trial of HIV-positive participants with CMD, the Friendship Bench intervention had no effect on adherence and viral suppression, possibly due to the absence of skill-based adherence training and a ceiling effect.

Estimating the welfare gains from anti-retroviral therapy in Sub-Saharan Africa

Since the start of the century, many countries in Sub-Saharan Africa have experienced large gains in life expectancy and average consumption levels. Around the same time, an unprecedented international effort has taken place to combat HIV/AIDS mortality with the expansion of anti-retroviral therapy (ART) across many of the hardest hit countries. In this paper, I estimate the impact of ART on average welfare over time in 42 countries using the equivalent consumption approach. I decompose the change in welfare to isolate the relative contribution of ART-driven improvements in life expectancy and consumption. The results indicate that ART has accounted for around 12% of total welfare growth in SSA between 2000 and 2017. In those countries most affected by HIV/AIDS, this figure rises to around 40%. Moreover, the estimates suggest that welfare in some of the worst-hit countries would have declined over time without the ART expansion.

Record linkage without patient identifiers: proof of concept using data from South Africa's national HIV program

Background

Linkage between health databases typically requires identifiers such as patient names and personal identification numbers. We developed and validated a record linkage strategy to combine administrative health databases without the use of patient identifiers, with application to South Africa's public sector HIV treatment program.

Methods

We linked CD4 counts and HIV viral loads from South Africa's HIV clinical monitoring database (TIER.Net) and the National Health Laboratory Service (NHLS) for patients receiving care between 2015-2019 in Ekurhuleni District (Gauteng Province). We used a combination of variables related to lab results contained in both databases (result value; specimen collection date; facility of collection; patient year and month of birth; and sex). Exact matching linked on exact linking variable values while caliper matching applied exact matching with linkage on approximate test dates (± 5 days). We then developed a sequential linkage approach utilising specimen barcode matching, then exact matching, and lastly caliper matching. Performance measures were sensitivity and positive predictive value (PPV); share of patients linked across databases; and percent increase in data points for each linkage approach.

Results

We attempted to link 2,017,290 lab results from TIER.Net (representing 523,558 unique patients) and 2,414,059 lab results from the NHLS database. Linkage performance was evaluated using specimen barcodes (available for a minority of records in TIER.net) as a "gold standard". Exact matching achieved a sensitivity of 69.0% and PPV of 95.1%. Caliper-matching achieved a sensitivity of 75.7% and PPV of 94.5%. In sequential linkage, we matched 41.9% of TIER.Net labs by specimen barcodes, 51.3% by exact matching, and 6.8% by caliper matching, for a total of 71.9% of labs matched, with PPV=96.8% and Sensitivity = 85.9%. The sequential approach linked 86.0% of TIER.Net patients with at least one lab result to the NHLS database (N=1,450,087). Linkage to the NHLS Cohort increased the number of laboratory results associated with TIER.Net patients by 62.6%.

Conclusions

Linkage of TIER.Net and NHLS without patient identifiers attained high accuracy and yield without compromising patient privacy. The integrated cohort provides a more complete view of patients' lab history and could yield more accurate estimates of HIV program indicators.

High frequency of memory stem cells with a distinct gene signature in HIV patients with treatment interruption

Reservoirs of HIV remain a major obstacle to the complete eradication of virus despite regular anti-retroviral therapy (ART). Memory stem cells (Tscm), one of the major reservoirs, are relatively less studied owing to their presence in lower numbers and inaccessible anatomical locations. We have evaluated the molecular characteristics of Tscms in patients with ART interruption (n = 15) versus patients on uninterrupted ART (n = 12) using flow cytometry. RNA sequencing was done in the sorted Tscms to study the differential gene expression. Patients with ART interruption had significantly lower baseline CD4+T-cell counts and high viral loads as compared to patients on ART. The former group had significantly higher frequency of CD4+ and CD8+Tscms with a higher expression of PD-1 on CD8+Tscms. The transcriptome profile of Tscm was significantly different among the patient groups. The main pathways were cellular and metabolic pathways, cellular development pathways, cell differentiation and negative regulation of cellular migratory pathways. An increased yet dysfunctional CD8+ memory stem cells describe HIV-1-infected patients with break-in ART and a distinct transcriptional signature of CD4+ Tscm as compared to those of patients on ART. A more detailed understanding of the biology and dynamics of Tscm in future studies is warranted. Strategies to improve the functionality of the CD8+ Tscm will help these patients to tackle the outburst of viral replication that occurs after the cessation of therapy.

Improving the quality of life of people living with HIV/AIDS: A cross-sectional study of the role of religion

Background

Previous studies have found religion as a useful tool in coping with chronic medical conditions including HIV/AIDS. Aim: This study assessed how religiosity and religious coping are associated with quality of life (QOL) among people living with HIV/AIDS (PLWHA).

Patients and Methods

This was a cross-sectional study of 140 HIV clinic attendees of a Nigerian tertiary health facility. Religiosity, religious coping and QOL were measured with religious orientation scale-revised (ROS-R), Brief Religious Coping (Brief RCOPE) and World Health Organization Quality of Life-Bref (WHOQOL-BREF), respectively. Correlation analysis assessed the relationship between ROS-R, Brief RCOPE and WHOQOL-BREF.

Results

: Intrinsic religiosity (IR) scores had a moderate positive correlation with psychological health domain of QOL (r = 0.4, N = 140, and P 0.001), and a weak positive correlation with physical health domain of QOL (r = 0.2, N = 140, and P 0.05). Extrinsic religiosity (ER) scores moderately correlated positively with the psychological health domain of QOL (r = 0.03, N = 140, and P 0.002), but weakly correlated positively with the physical health domain (r = 0.2, N = 140, and P 0.02). Positive religious coping (PRC) scores moderately correlated positively with the psychological health domain (r = 0.03, N = 140, and P 0.05) and weakly correlated positively with physical health domain of QOL (r = 0.2, N = 140, and P 0.02). Extrinsic religiosity social (ERS) scores had a moderate positive correlation with the social relationships domain (r = 0.4, N = 140, P 0.001).

Conclusion

Increased ER, IR orientations and Positive Religious Coping appear to improve the psychological and physical health domains ofQOL QOL Therefore, religiosity should be encouraged among PLWHA to improve QOL.

Mode of HIV acquisition among adolescents living with HIV in resource-limited settings: A data-driven approach from South Africa

Adolescents living with HIV (ALHIV) face unique treatment and care challenges which may differ by how they acquired HIV, whether vertically (in-utero, perinatal or postnatal exposure during breastfeeding) or sexually (sexual exposure). Distinguishing and documenting the mode of HIV acquisition (MOHA) is crucial to further research on the different needs and outcomes for ALHIV and to tailor HIV services to their needs. Age-based cut-offs have been used to attribute MOHA but have not been validated. We analysed data from a three-wave cohort of n = 1107 ALHIV part of a longitudinal study in South Africa. Age-based MOHA was allocated using age at ART initiation, validated against a logic-tree model based on literature-hypothesised factors: self-reported HIV, sexual, and family history. After testing six ART initiation age cut-offs (10 to 15 years old), we determined the optimal MOHA cut-off age by calculating the sensitivity and specificity for each cut-off, measured against the final logic-tree allocation. Following validation using this longitudinal study, the methodology is extended to 214 additional third-wave participants-adolescent girls and young women living with HIV who became mothers before the age of 20. Finally, descriptive statistics of the final allocations are presented. Among the 1,063 (96.0%) cohort study participants classified, 68.7% acquired HIV vertically, following validation. ART initiation before cut-off age 10 had the highest sensitivity (58.9%) but cut-off age 12 had the largest area under the curve (AUC) (0.712). Among the additional young mothers living with HIV, 95.3% were estimated to have acquired it sexually, following the same algorithm. For this group, while cut-off ages 10 to 12 had the highest sensitivity (92.2%), age 14 had the highest AUC (0.703). ART initiation before 10 years old is strongly associated with vertical HIV acquisition. Therefore, a cut-off age of 10 would remain the recommendation in LMIC regions with similar epidemiology as South Africa for determining MOHA in research and clinic settings.

Effect of the Friendship Bench intervention on antiretroviral therapy outcomes and mental health symptoms in rural Zimbabwe: A cluster randomized trial

Importance

Common mental disorders (CMD) are prevalent in people living with HIV and associated with suboptimal antiretroviral therapy (ART) adherence.

Objective

To assess the effect of a lay health worker-led psychological intervention on adherence to ART, virologic suppression and mental health symptoms.

Design

Pragmatic cluster trial with block randomization of health facilities. Treatment assignment was known to participants, providers, evaluators, and data analysts. Recruitment started in October 2018 and the last follow-up visit was done in December 2020. Participants were followed up for 12 months.

Setting

Sixteen public health care facilities in Bikita, a rural district in Masvingo Province, about 300 km south of Harare.

Participants

Men and non-pregnant women aged 18 years or older who spoke English or Shona, screened positive for CMD (Shona Symptoms Questionnaire [SSQ]-14 score ≥9), had received first-line ART for at least six months, had no WHO clinical stage 4 disease, no psychotic symptoms, and gave informed consent.

Intervention

The Friendship Bench, a lay health worker-led intervention consisting of six weekly individual counselling sessions of problem-solving therapy and optional peer-led group support.

Main Outcomes and Measures

The primary outcome was Medication Event Monitoring System (MEMS) mean adherence between 2-6 months of follow-up. Secondary outcomes included mean adherence between 1-12 months, change from baseline SSQ-14 and Patient Health Questionnaire (PHQ-9) score at 3, 6, 9, and 12 months and change in viral load suppression (viral load <1000 copies per mL) at months 6 and 12.

Results

We recruited 516 participants, 244 in Friendship bench and 272 in standard care facilities. The mean age was 45.6 years (SD 10.9), and most participants were women (84.9%). In the Friendship Bench group, 88.1% of participants attended all six individual counselling sessions. Rates of adherence (>85%) and virologic suppression (>90%) were high in both groups. The intervention had no statistically significant effect on adherence or viral suppression. Declines in SSQ-14 scores from baseline to 3 months (-1.65, 95% CI -3.07 to -0.24), 6 months (-1.57, 95% CI -2.98 to -0.15), and 9 months (-1.63, 95% CI -3.05 to -0.22) were greater in the Friendship Bench than the standard care group (p<0.05). There were no differences in the decline in the SSQ-14 scores from baseline to 12 months and in declines in PHQ-9 scores from baseline to 3, 6, 9, and 12 months.

Conclusions and Relevance

The Friendship Bench intervention is a feasible and acceptable approach to closing the treatment gap in mental health care in rural Zimbabwe. The intervention improved CMD symptoms but the intervention effect was smaller than previously shown in an urban setting. The intervention had no effect on adherence and viral suppression, possibly due to the absence of skill-based adherence training and ceiling effect.

Trial registration

ClinicalTrials.gov Identifier: NCT03704805.

Key points

Question: Does the Friendship Bench intervention improve antiretroviral therapy (ART) adherence, viral suppression and mental health symptoms in people living with HIV in rural Zimbabwe?Findings: In this cluster-randomized trial, participants in the intervention group had a significantly greater decrease in symptoms of common mental disorders than those in the control group, but the intervention showed no significant effect on antiretroviral therapy (ART) adherence or viral suppression.Meaning: The intervention did not affect adherence and viral suppression and the effect of the intervention on mental health symptoms was smaller than previously shown.

Mental Health, ART Adherence, and Viral Suppression Among Adolescents and Adults Living with HIV in South Africa: A Cohort Study

We followed adolescents and adults living with HIV aged older than 15 years who enrolled in a South African private-sector HIV programme to examine adherence and viral non-suppression (viral load > 400 copies/mL) of participants with (20,743, 38%) and without (33,635, 62%) mental health diagnoses. Mental health diagnoses were associated with unfavourable adherence patterns. The risk of viral non-suppression was higher among patients with organic mental disorders [adjusted risk ratio (aRR) 1.55, 95% confidence interval (CI) 1.22-1.96], substance use disorders (aRR 1.53, 95% CI 1.19-1.97), serious mental disorders (aRR 1.30, 95% CI 1.09-1.54), and depression (aRR 1.19, 95% CI 1.10-1.28) when compared with patients without mental health diagnoses. The risk of viral non-suppression was also higher among males, adolescents (15-19 years), and young adults (20-24 years). Our study highlights the need for psychosocial interventions to improve HIV treatment outcomes-particularly of adolescents and young adults-and supports strengthening mental health services in HIV treatment programmes.

Attrition from Care Among Men Initiating ART in Male-Only Clinics Compared with Men in General Primary Healthcare Clinics in Khayelitsha, South Africa: A Matched Propensity Score Analysis

Men have higher rates of attrition from antiretroviral therapy (ART) programs than women. In Khayelitsha, a high HIV prevalence area in South Africa, two public sector primary healthcare clinics offer services, including HIV testing and treatment, exclusively to men. We compared attrition from ART care among men initiating ART at these clinics with male attrition in six general primary healthcare clinics in Khayelitsha. We described baseline characteristics of patients initiating ART at the male and general clinics from 1 January 2014 to 31 March 2018. We used exposure propensity scores (generated based on baseline health and age) to match male clinic patients 1:1 to males at other clinics. The association between attrition (death or loss to follow-up, defined as no visits for nine months) and clinic type was estimated using Cox proportional hazards regression. Follow-up time began at ART initiation and ended at attrition, clinic transfer, or dataset closure. Before matching, patients from male clinics (n = 784) were younger than males from general clinics (n = 2726), median age: 31.2 vs 35.5 years. Those initiating at male clinics had higher median CD4 counts at ART initiation [Male Clinic 1: 329 (IQR 210-431), Male Clinic 2: 364 (IQR 260-536), general clinics 258 (IQR 145-398), cells/mm³]. In the matched analysis (1451 person-years, 1568 patients) patients initiating ART at male clinics had lower attrition (HR 0.71; 95% CI 0.60-0.85). In separate analyses for each of the two male clinics, only the more established male clinic showed a protective effect. Male-only clinics reached younger, healthier men, and had lower ART attrition than general services. These findings support clinic-specific adaptations to create more male-friendly environments.

Linkage to HIV Care Following HIV Self-testing Among Men: Systematic Review of Quantitative and Qualitative Studies from Six Countries in Sub-Saharan Africa

Gender disparities are pervasive throughout the HIV care continuum in sub-Saharan Africa, with men testing, receiving treatment, and achieving viral suppression at lower rates, and experiencing mortality at higher rates, compared with women. HIV self-testing (HIVST) has been shown to be highly acceptable among men in sub-Saharan Africa. However, evidence on linkage to HIV care following a reactive HIVST result is limited. In this systematic review, we aimed to synthesize the quantitative and qualitative literature from sub-Saharan Africa on men's rates of linkage to HIV care after receiving a reactive HIVST result. We systematically searched 14 bibliometric databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) flow diagram was used to document the screening results. The Mixed Methods Appraisal Tool (MMAT) was used to assess the methodological quality of the included studies. Of 22,446 references screened, 15 articles were eligible for inclusion in this review. Linkage to HIV care following a reactive HIVST result was subject to several barriers: financial constraints due to travelling costs, potential long waiting hours at the clinics, stigma, discrimination, and privacy concerns. Men's rates of seeking confirmatory testing and linking to HIV care following a reactive HIVST result were inconsistent across studies. Combining financial incentives with HIVST was found to increase the likelihood of linking to HIV care following a reactive HIVST result. The variable rates of linkage to HIV care following a reactive HIVST result suggest a need for further research and development into strategies to increase linkage to HIV care.

Diet, physical activity, and obesity among ART-experienced people with HIV in South Africa

The prevalence of non-communicable diseases (NCDs) is increasing in South Africa, in part due to poor nutrition, physical inactivity, and obesity. We characterized the habits and understanding of diet, exercise, and obesity among people with HIV (PWH) taking antiretroviral therapy (ART). We conducted a cross-sectional study of ART-experienced PWH attending an HIV community health center near Cape Town, South Africa. We included PWH currently prescribed ART, older than 21y, and not pregnant. We collected demographic and clinical information and interviewed participants regarding their behaviors and knowledge related to diet, physical activity, and obesity. From March 2015 - February 2016, we enrolled 458 participants. Self-reported diets were low in nutritional diversity: 202 reported eating only starch and protein without vegetable/fruit in the prior 24 h. Although most participants (96%) acknowledged that exercise had health benefits, only 215 participants engaged in daily 30-minute walking or exercise. One quarter of participants recognized nocontributors to obesity, and almost 20% identified no health problems associated with obesity. Participants had diets low in nutritional diversity, modest exercise habits, and limited understanding of the impact of obesity on health. Further understanding of barriers to improving diet and exercise and reducing obesity are essential, especially as PWH age.

Traditional and biomedical health practices of adolescent boys and young men living with perinatally-acquired HIV in the Eastern Cape Province of South Africa

Men are less vulnerable to HIV acquisition than women, but have poorer HIV-related health outcomes. They access HIV services less, and are more likely to die on antiretroviral therapy. The adolescent epidemic presents further challenges, and AIDS-related illness is the leading cause of death among adolescents in sub-Saharan Africa. We explored the health practices of adolescent boys and young men (aged 13-22) living with perinatally-acquired HIV and the processes through which these practices are formed and sustained. We engaged health-focused life history narratives (n = 35), semi-structured interviews (n = 32) and analysis of health facility files (n = 41), alongside semi-structured interviews with traditional and biomedical health practitioners (n = 14) in the Eastern Cape, South Africa. Participants did not access traditional products and services for HIV, a finding that deviates from much of the literature. Findings suggest that health practices are mediated not only by gender and culture, but also childhood experiences of growing up deeply embedded in the biomedical health system.

Study protocol: A randomised trial of the effectiveness of the Common Elements Treatment Approach (CETA) for improving HIV treatment outcomes among women experiencing intimate partner violence in South Africa

INTRODUCTION

Intimate partner violence (IPV) is a barrier to consistent HIV treatment in South Africa. Previous trials have established that the Common Elements Treatment Approach (CETA), a cognitive-behavioural-based intervention, is effective in reducing mental and behavioural health problems but has not been trialled for effectiveness in improving HIV outcomes. This paper describes the protocol for a randomised trial that is testing the effectiveness of CETA in improving HIV treatment outcomes among women experiencing IPV in South Africa.

METHODS AND ANALYSIS

We are conducting a randomised trial among HIV-infected women on antiretroviral therapy, who have experienced sexual and/or physical IPV, to test the effect of CETA on increasing retention and viral suppression and reducing IPV. Women living with HIV who have an unsuppressed viral load or are at high risk for poor adherence and report experiencing recent IPV, defined as at least once within in the last 12 months, will be recruited from HIV clinics and randomised 1:1 to receive CETA or an active attention control (text message reminders). All participants will be followed for 24 months. Follow-up HIV data will be collected passively using routinely collected medical records. HIV outcomes will be assessed at 12 and 24 months post-baseline. Questionnaires on violence, substance use and mental health will be administered at baseline, post-CETA completion and at 12 months post-baseline. Our primary outcome is retention and viral suppression (<50 copies/mL) by 12 months post-baseline. We will include 400 women which will give us 80% power to detect an absolute 21% difference between arms. Our primary analysis will be an intention-to-treat comparison of intervention and control by risk differences with 95% CIs.

The costs of interventions for type 2 diabetes mellitus, hypertension and cardiovascular disease in South Africa - a systematic literature review

BACKGROUND

In the context of a move to universal health coverage, three separate systematic reviews were conducted to summarise available evidence on the direct costs of interventions for type 2 diabetes mellitus, hypertension, and cardiovascular disease in South Africa.

METHODS

PubMed® and Web of Science was searched for literature published between 01 and 1995 and 27 October 2022. Additionally, reference and citations lists of retrieved articles and experts were consulted. We also tracked reference lists of previous, related systematic reviews. Eligible publications were cost analyses of clinical interventions targeted at adults age 15 + reporting primary estimates of in- and out-of-hospital costs from a provider perspective. Costs were extracted and converted to 2021 US dollars, and article methodological and reporting quality was appraised using the 2013 CHEERS checklist.

RESULTS

Of the 600, 1,172 and 1,466 identified publications for type 2 diabetes mellitus, hypertension, and cardiovascular disease, respectively, 10, 12, and 17 met full inclusion criteria. 60% of articles reported cardiovascular disease costs, 52% were of good reporting quality, and 10%, 50%, and 39% of type 2 diabetes mellitus, hypertension and cardiovascular disease papers reported private-sector costs only. Hypertension drug costs ranged from $2 to $85 per person-month, while type 2 diabetes mellitus drug costs ranged between $57 and $630 per person-year (ppy). Diabetes-related complication treatment costs ranged from $55 for retinopathy treatment to $25,193 ppy for haemodialysis, while cardiovascular disease treatment costs were between $160 and $37,491 ppy. Drugs and treatment of complications were major cost drivers for hypertension and type 2 diabetes mellitus, while hospitalisation drove cardiovascular disease costs.

CONCLUSION

The intervention costs of type 2 diabetes mellitus, hypertension and cardiovascular disease care have received more attention recently, particularly diabetes-related complications and cardiovascular disease. However, 39% of identified cardiovascular disease treatment costs used a private sector perspective, leaving significant research gaps in the public sector and the cheaper to treat hypertension and type 2 diabetes mellitus. This review fills an information gap regarding the intervention costs of these diseases in South Africa.

Comprehensive assessment of neurocognitive function, inflammation markers, and adiposity in treated HIV and control

To compare the neurocognitive scores between persons living with human immunodeficiency virus (PLWH) and persons without human immunodeficiency virus (HIV) and assess the relationship between neurocognition, HIV status and variables, inflammation, and body composition measures. Cross-sectional study involving 225 participants (126 PLWH on antiretroviral therapy [ART] and 99 persons without HIV). For the first time in HIV, we used Cognivue®, an food and drug administration (FDA)-approved computer-based test to assess cognitive function. The test was calibrated to individuals' unique cognitive ability and measured 6 cognitive domains and 2 performance parameters. Markers of inflammation, immune activation, insulin resistance, and body fat composition (using dual-energy X-ray absorptiometry scan) were collected. Classical t tests, chi-square tests, and spearman correlations were used to compare and explore relationships between variables. Inverse probability weighting adjusted average treatment effect models were performed to evaluate the differences between PLWH and persons without HIV, adjusting for age, race, sex, and heroin use. Overall, 64% were male, 46% were Black, with a mean age of 43 years. Among PLWH, 83% had an undetectable HIV-1 RNA level (≤20 copies/mL). Compared persons without HIV, PLWH performed poorer across 4 domains: visuospatial (P = .035), executive function (P = .029), naming/language (P = .027), and abstraction (P = .018). In addition, PLWH had a significantly longer processing speed time compared to controls (1686.0 ms vs 1606.0 ms [P = .007]). In PLWH, lower cognitive testing domain scores were associated with higher inflammatory markers (high sensitivity C-reactive protein [hsCRP]) and with higher total fat and visceral adipose tissue (P < .05). Neurocognitive impairment (NCI) in HIV is associated with inflammation and total and central adiposity.

Differences in healthy longevity by HIV status and viral load among older South African adults: an observational cohort modelling study

BACKGROUND

The population of people living with HIV in South Africa is rapidly ageing due to increased survivorship attributable to antiretroviral therapy (ART). We sought to understand how the combined effects of HIV and ART have led to differences in healthy longevity by HIV status and viral suppression in this context.

METHODS

In this observational cohort modelling study we use longitudinal data from the 2015 baseline interview (from Nov 13, 2014, to Nov 30, 2015) and the 2018 longitudinal follow-up interview (from Oct 12, 2018, to Nov 7, 2019) of the population-based study Health and Ageing in Africa: a Longitudinal Study of an INDEPTH Community in South Africa (HAALSI) to estimate life expectancy and disability-free life expectancy (DFLE) of adults aged 40 years and older in rural South Africa. Respondents who consented to HIV testing, responded to survey questions on disability, and who were either interviewed in both surveys or who died between survey waves were included in the analysis. We estimate life expectancy and DFLE by HIV status and viral suppression (defined as <200 copies per mL) using Markov-based microsimulation.

FINDINGS

Among the 4322 eligible participants from the HAALSI study, we find a clear gradient in remaining life expectancy and DFLE based on HIV serostatus and viral suppression. At age 45 years, the life expectancy of a woman without HIV was 33·2 years (95% CI 32·0-35·0), compared with 31·6 years (29·2-34·1) a woman with virally suppressed HIV, and 26·4 years (23·1-29·1) for a woman with unsuppressed HIV; life expectancy for a 45 year old man without HIV was 27·2 years (25·8-29·1), compared with 24·1 years (20·9-27·2) for a man with virally suppressed HIV, and 17·4 years (15·0-20·3) for a man with unsuppressed HIV. Men and women with viral suppression could expect to live nearly as many years of DFLE as HIV-uninfected individuals at ages 45 years and 65 years.

INTERPRETATION

These results highlight the tremendous benefits of ART for population health in high-HIV-prevalence contexts and reinforce the need for continued work in making ART treatment accessible to ageing populations.

Impact of HIV infection on survival among women with stage I-III breast cancer: Results from the South African breast cancer and HIV outcomes study

In some countries of sub-Saharan Africa, the prevalence of HIV exceeds 20%; in South Africa, 20.4% of people are living with HIV. We examined the impact of HIV infection on the overall survival (OS) of women with nonmetastatic breast cancer (BC) enrolled in the South African Breast Cancer and HIV Outcomes (SABCHO) study. We recruited women with newly diagnosed BC at six public hospitals from 1 July 2015 to 30 June 2019. Among women with stages I-III BC, we compared those with and without HIV infection on sociodemographic, clinical, and treatment factors. We analyzed the impact of HIV on OS using multivariable Cox proportional hazard models. Of 2367 women with stages I-III BC, 499 (21.1%) had HIV and 1868 (78.9%) did not. With a median follow-up of 29 months, 2-year OS was poorer among women living with HIV (WLWH) than among HIV-uninfected women (72.4% vs 80.1%, P < .001; adjusted hazard ratio (aHR) 1.49, 95% confidence interval (CI) = 1.22-1.83). This finding was consistent across age groups ≥45 years and <45 years, stage I-II BC and stage III BC, and ER/PR status (all P < .03). Both WLWH with <50 viral load copies/mL and WLWH with ≥50 viral load copies/mL had poorer survival than HIV-uninfected BC patients [aHR: 1.35 (1.09-1.66) and 1.54 (1.20-2.00), respectively], as did WLWH who had ≥200 CD4+ cells/mL at diagnosis [aHR: 1.39 (1.15-1.67)]. Because receipt of antiretroviral therapy has become widespread, WLWH is surviving long enough to develop BC; more research is needed on the causes of their poor survival.

Cyclical Engagement in HIV Care: A Qualitative Study of Clinic Transfers to Re-enter HIV Care in Cape Town, South Africa

Long-term patient engagement and retention in HIV care is an ongoing challenge in South Africa's strained health system. However, some patients thought to be "lost to follow-up" (LTFU) may have "transferred" clinics to receive care elsewhere. Through semi-structured interviews, we explored the relationship between clinic transfer and long-term patient engagement among 19 treatment-experienced people living with HIV (PLWH) who self-identified as having engaged in a clinic transfer at least once since starting antiretroviral therapy (ART) in Gugulethu, Cape Town. Our findings suggest that patient engagement is often fluid, as PLWH cycle in and out of care multiple times during their lifetime. The linear nature of the HIV care cascade model poorly describes the lived realities of PLWH on established treatment. Further research is needed to explore strategies for reducing unplanned clinic transfers and offer more supportive care to new and returning patients.

Conditional Economic Incentives for HIV Treatment Adherence: Aligning Adolescent Developmental Hallmarks with Behavioral Economic Theory to Improve HIV Treatment Adherence

Adolescent-tailored antiretroviral therapy (ART) adherence interventions take place within the context of unique developmental stage. Suboptimal ART adherence among adolescents living with HIV in South Africa underscores that interventions are urgently needed to improve adherence. We conducted semistructured in-depth interviews with 35 adolescents aged 10-19 years living with HIV. In addition, 14 clinicians and 35 caregivers were interviewed to provide a diverse perspective on barriers and facilitators of medication adherence for adolescents living with HIV (ALWH). Thematic coding was utilized for this analysis. Our main findings were organized by following a priori themes: (1) acceptability of conditional economic incentives (CEIs) as an adherence intervention strategy for adolescents, (2) predicted behavioral impacts, and the (3) durability of CEIs to ensure medication adherence for adolescents in the long term. Subthemes that emerged included CEIs as tool to overcome competing demands, increasing intrinsic motivation and orientation toward the future, and optimal timing of the intervention. Exposure to a CEI intervention during early adolescence (ages 10-13) may be a particularly helpful intervention as CEIs may have long-lasting effects given that habit-formation behavior is developed during early adolescence. There is little consensus on effect duration from the perspective of adolescents, clinicians, and caregivers. Future studies should continue to explore the impact of CEIs for long-term ART adherence.

Multiple High-Risk HPV Types Contribute to Cervical Dysplasia in Ugandan Women Living With HIV on Antiretroviral Therapy

BACKGROUND

Cervical cancer mortality remains high in sub-Saharan Africa, especially among women living with HIV (WLWH). Characterization of prevalent high-risk human papillomavirus (hrHPV) types and immune function in WLWH with cervical abnormalities despite antiretroviral therapy (ART) can inform prevention strategies.

SETTING

Kampala, Uganda.

METHODS

From 2017 to 2020, we enrolled Ugandan women with cervical dysplasia detected with visual inspection with acetic acid (VIA). WLWH were required to be on ART >3 months with plasma HIV RNA <1000 copies/mL. Biopsies from VIA-positive lesions underwent histopathologic grading and cervical swab specimens were tested for hrHPV. Clinical correlations were evaluated with Poisson regression to estimate adjusted prevalence ratios (aPR).

RESULTS

One hundred eighty-eight WLWH and 116 HIV-seronegative women participated. Among WLWH, median ART duration was 6 years and median CD4 667 cells/µL. Cervical intraepithelial neoplasia (CIN) grade 2/3 was found in 29% of WLWH versus 9% of HIV-seronegative women. In women with CIN1 or without histopathology-confirmed dysplasia, hrHPV (aPR [95% confidence interval]: 2.17 [1.43 to 3.29]) and multiple hrHPV (aPR 3.73 [1.07 to 13.1]) were more common in WLWH, as were vaccine-targeted and vaccine-untargeted hrHPVtypes. Differences in hrHPV prevalence by HIV serostatus were not observed in women with CIN2/3 (interaction P < 0.01). Among WLWH, low CD4/8 ratio was associated with hrHPV while detectable plasma HIV RNA (20-1000 copies/mL) was associated with CIN2/3 or invasive cancer.

CONCLUSION

Despite ART, WLWH with cervical VIA abnormalities remain at elevated risk for multiple hrHPV and high-grade dysplasia. Cervical cancer prevention and research tailored for WLWH are warranted in the ART era.

Changes to the Simian Immunodeficiency Virus (SIV) Reservoir and Enhanced SIV-Specific Responses in a Rhesus Macaque Model of Functional Cure after Serial Rounds of Romidepsin Administrations

HIV persistence requires lifelong antiretroviral therapy (ART), calling for a cure. The histone deacetylase inhibitor, romidepsin, is used in the "shock and kill" approach with the goal of reactivating virus and subsequently clearing infected cells through cell-mediated immune responses. We tested serial and double infusions of romidepsin in a rhesus macaque (RM) model of SIV functional cure, which controls virus without ART. Off ART, romidepsin reactivated SIV in all RMs. Subsequent infusions resulted in diminished reactivation, and two RMs did not reactivate the virus after the second or third infusions. Therefore, those two RMs received CD8-depleting antibody to assess the replication competence of the residual reservoir. The remaining RMs received double infusions, i.e., two doses separated by 48-h. Double infusions were well tolerated, induced immune activation, and effectively reactivated SIV. Although reactivation was gradually diminished, cell-associated viral DNA was minimally changed, and viral outgrowth occurred in 4/5 RMs. In the RM which did not reactivate after CD8 depletion, viral outgrowth was not detected in peripheral blood mononuclear cells (PBMC)-derived CD4+ cells. The frequency of SIV-specific CD8+ T cells increased after romidepsin administration, and the increased SIV-specific immune responses were associated, although not statistically, with the diminished reactivation. Thus, our data showing sequential decreases in viral reactivation with repeated romidepsin administrations with all RMs and absence of viral reactivation after CD8+ T-cell depletion in one animal suggest that, in the context of healthy immune responses, romidepsin affected the inducible viral reservoir and gradually increased immune-mediated viral control. Given the disparities between the results of romidepsin administration to ART-suppressed SIVmac239-infected RMs and HIV-infected normal progressors compared to our immune-healthy model, our data suggest that improving immune function for greater SIV-specific responses should be the starting point of HIV cure strategies. IMPORTANCE HIV cure is sought after due to the prevalence of comorbidities that occur in persons with HIV. One of the most investigated HIV cure strategies is the "shock and kill" approach. Our study investigated the use of romidepsin, a histone deacetylase (HDAC) inhibitor, in our rhesus macaque model of functional cure, which allows for better resolution of viral reactivation due to the lack of antiretroviral therapy. We found that repeated rounds of romidepsin resulted in gradually diminished viral reactivation. One animal inevitably lacked replication-competent virus in the blood. With the accompanying enhancement of the SIV-specific immune response, our data suggest that there is a reduction of the viral reservoir in one animal by the cell-mediated immune response. With the differences observed between our model and persons living with HIV (PWH) treated with romidepsin, specifically in the context of a healthy immune system in our model, our data thereby indicate the importance of restoring the immune system for cure strategies.

Early mortality in a cohort of people living with HIV in Rio de Janeiro, Brazil, 2004-2015: a persisting problem

BACKGROUND

Global mortality from AIDS-related diseases has been declining since 2005, resulting primarily from the widespread use and early initiation of combination antiretroviral therapy. Despite the significant improvements, high rates of early mortality, usually defined as that occurring within the 1st year of entry to care, have been observed, especially in resource-limited settings. This analysis draws upon data from an observational cohort of people with HIV (PWH) followed at a reference center for HIV/AIDS care and research in the city of Rio de Janeiro, Brazil, to identify the pattern and factors associated with early mortality.

METHODS

The study population includes PWH aged 18 or older followed at the National Institute of Infectious Diseases Evandro Chagas who were enrolled between 2004 and 2015. The primary outcome was early mortality, defined as deaths occurring within 1 year of inclusion in the cohort, considering two follow-up periods: 0 to 90 days (very early mortality) and 91 to 365 days (early mortality). Cox proportional hazards models were used to identify the variables associated with the hazard of very early and early mortality.

RESULTS

Overall, 3879 participants contributed with 3616.4 person-years of follow-up. Of 220 deaths, 132 happened in the first 90 days and 88 between 91 and 365 days. Very early mortality rate ratios (MRR) show no statistically significant temporal differences between the periods 2004-2006 to 2013-2015. In contrast, for early mortality, a statistically significant decreasing trend was observed: mortality rates in the periods 2004-2006 (MR = 5.5; 95% CI 3.9-7.8) and 2007-2009 (MR = 3.9; 95% CI 2.7-5.7) were approximately four and three-fold higher when compared to 2013-2015 (MR = 1.4; 95% CI 0.7-2.7). Low CD4 count and prior AIDS-defining illness were strongly associated with higher hazard ratios of death, especially when considering very early mortality.

CONCLUSIONS

The present study shows an excess of mortality in the 1st year of follow-up with no changes in the mortality rates within 90 days among PWH from Rio de Janeiro. We note the significant impact of initiating treatment with immunosuppression, as evidenced by the increased risk of death among those with low CD4 cell count and with AIDS-defining illnesses.

The health impact of free access to antiretroviral therapy in South Africa

Since 2004 the South African government has rolled out free antiretroviral therapy (ART) at public health care facilities nationwide. No prior studies have estimated the impact of the ART rollout on health and survival using a longitudinal household survey with national coverage. We match household member deaths and self-assessed health from a large national longitudinal survey to community-level ART availability in clinics to estimate the reduction in mortality and morbidity attributable to ART availability between 2006 and 2016, using a difference-in-difference model. Our analysis focuses on black Africans aged 25-49 because this demographic group represents more than two-thirds of all South African HIV cases. We find that the rollout of free ART has reduced annual mortality by 27% and decreased the likelihood of reporting poor health by 36% for black Africans aged 25-49. These estimates amount to annual reductions in this demographic category of 31% in annual mortality and 47% in individuals reporting poor health. Our findings confirm that making ART treatment freely available nationwide has had a dramatic impact in terms of both prolonged survival and improved health, with most of these gains concentrated in the high HIV prevalence group of black Africans aged 25-49.

Mortality in HIV and tuberculosis patients following implementation of integrated HIV-TB treatment: Results from an open-label cluster-randomized trial

BACKGROUND

HIV-TB treatment integration reduces mortality. Operational implementation of integrated services is challenging. This study assessed the impact of quality improvement (QI) for HIV-TB integration on mortality within primary healthcare (PHC) clinics in South Africa.

METHODS

An open-label cluster randomized controlled study was conducted between 2016 and 2018 in 40 rural clinics in South Africa. The study statistician randomized PHC nurse-supervisors 1:1 into 16 clusters (eight nurse-supervisors supporting 20 clinics per arm) to receive QI, supported HIV-TB integration intervention or standard of care (control). Nurse supervisors and clinics under their supervision, based in the study health districts were eligible for inclusion in this study. Nurse supervisors were excluded if their clinics were managed by municipal health (different resource allocation), did not offer co-located antiretroviral therapy (ART) and TB services, services were performed by a single nurse, did not receive non-governmental organisation (NGO) support, patient data was not available for > 50% of attendees. The analysis population consists of all patients newly diagnosed with (i) both TB and HIV (ii) HIV only (among patients previously treated for TB or those who never had TB before) and (iii) TB only (among patients already diagnosed with HIV or those who were never diagnosed with HIV) after QI implementation in the intervention arm, or enrolment in the control arm. Mortality rates was assessed 12 months post enrolment, using unpaired t-tests and cox-proportional hazards model. (Clinicaltrials.gov, NCT02654613, registered 01 June 2015, trial closed).

FINDINGS

Overall, 21 379 participants were enrolled between December 2016 and December 2018 in intervention and control arm clinics: 1329 and 841 HIV-TB co-infected (10·2%); 10 799 and 6 611 people living with Human Immunodeficiency Virus (HIV)/ acquired immunodeficiency syndrome (AIDS) (PLWHA) only (81·4%); 1 131 and 668 patients with TB only (8·4%), respectively. Average cluster sizes were 1657 (range 170-5782) and 1015 (range 33-2027) in intervention and control arms. By 12 months, 6529 (68·7%) and 4074 (70·4%) were alive and in care, 568 (6·0%) and 321 (5·6%) had completed TB treatment, 1078 (11·3%) and 694 (12·0%) were lost to follow-up, with 245 and 156 deaths occurring in intervention and control arms, respectively. Mortality rates overall [95% confidence interval (CI)] was 4·5 (3·4-5·9) in intervention arm, and 3·8 (2·6-5·4) per 100 person-years in control arm clusters [mortality rate ratio (MRR): 1·19 (95% CI 0·79-1·80)]. Mortality rates among HIV-TB co-infected patients was 10·1 (6·7-15·3) and 9·8 (5·0-18·9) per 100 person-years, [MRR: 1·04 (95% CI 0·51-2·10)], in intervention and control arm clusters, respectively.

INTERPRETATION

HIV-TB integration supported by a QI intervention did not reduce mortality in HIV-TB co-infected patients. Demonstrating mortality benefit from health systems process improvements in real-world operational settings remains challenging. Despite the study being potentially underpowered to demonstrate the effect size, integration interventions were implemented using existing facility staff and infrastructure reflecting the real-world context where most patients in similar settings access care, thereby improving generalizability and scalability of study findings.

So Pathogenic or So What?-A Brief Overview of SIV Pathogenesis with an Emphasis on Cure Research

HIV infection requires lifelong antiretroviral therapy (ART) to control disease progression. Although ART has greatly extended the life expectancy of persons living with HIV (PWH), PWH nonetheless suffer from an increase in AIDS-related and non-AIDS related comorbidities resulting from HIV pathogenesis. Thus, an HIV cure is imperative to improve the quality of life of PWH. In this review, we discuss the origins of various SIV strains utilized in cure and comorbidity research as well as their respective animal species used. We briefly detail the life cycle of HIV and describe the pathogenesis of HIV/SIV and the integral role of chronic immune activation and inflammation on disease progression and comorbidities, with comparisons between pathogenic infections and nonpathogenic infections that occur in natural hosts of SIVs. We further discuss the various HIV cure strategies being explored with an emphasis on immunological therapies and "shock and kill".

Re-Engagement into HIV Care: A Systematic Review

Identifying evidence-based interventions that can optimize the re-engagement into care of people living with HIV is necessary to achieve and sustain HIV epidemic control. We conducted a systematic review of interventions for re-engagement into HIV care to examine the accumulated evidence and to identify similarities and differences across studies. Between January and March 2020, we searched MEDLINE, Embase, CINAHL, and PsycINFO databases for publications from 1996 to 2020. We screened 765 references and selected 125 publications for full-text review. For the nine included studies, the intervention centered on (1) integration of clinic and HIV surveillance data; (2) additional or different levels of support provided by healthcare workers; or (3) multi-component intervention. Irrespective of the interventions, mixed results were found for re-engagement into care or ART re-initiation. None of the studies led to an improvement in viral suppression. Re-engagement in HIV care is critical for longitudinal HIV and national program success. Standardizing definitions for out-of-care and re-engagement would facilitate the comparison of interventions. Rigorous study designs to assess strategies to enhance HIV re-engagement are warranted.

"The Money, It's OK but It's not OK": Patients' and Providers' Perceptions of the Acceptability of Cash Incentives for HIV Treatment Initiation in Cape Town, South Africa

Incentive-based interventions are used to encourage HIV testing, linkage to HIV care, and antiretroviral therapy (ART) adherence. Studies assessing efficacy of cash incentives have raised questions about the perceived ethicality of and attitudes towards incentives. Here we explore patients' and health providers' perspectives of the acceptability of a conditional cash transfer for ART initiation after receiving a positive HIV test through community-based services in resource-poor communities in Cape Town, South Africa. Drawing on in-depth interviews with patients and health care workers (HCWs), we find that, despite the perception that cash incentives are effective in promoting ART initiation, significant ambivalence surrounds the acceptability of such incentives. The receipt of a financial incentive was highly moralized, and fraught with challenges. Increasing the acceptability of cash incentives through careful design and delivery of interventions is central to the potential of this type of intervention for improving outcomes along the HIV care continuum.

[Evolution of HIV infection in indigenous peoples in Central Brazil]

Distribution of the AIDS epidemic in Brazil is associated with a wide range of factors that determine different population groups' greater or lesser vulnerability. The study's objective was to analyze clinical and laboratory characteristics of HIV/AIDS in individuals 13 years or older and the evolution to death in the indigenous population assisted by the Special Indigenous Health District of the State of Mato Grosso do Sul, Brazil. A descriptive and retrospective study was performed on the clinical conditions and evolution of the disease from 2001 to 2014, based on three secondary databases. The study assessed time in progression to AIDS, time in progression to death, viral load, CD4+ T-lymphocyte count, and survival time. A total of 103 cases of HIV infection were identified, of which 48.5% progressed to AIDS, 60% in less than a year since diagnosis. Forty deaths were recorded, 77.5% of which due to HIV infection. Of those who died, only 30% had survived for more than a year. The study suggests that diagnosis of HIV infection occurred in advanced stages of the disease (i.e., late), and points to deficient diagnostic coverage. Rapid progression to death and short survival time are indicative of insufficient access to specialized health services, as well as disconnection and deficient collaboration between the Indigenous Health District, municipalities, and the state.

HIV/AIDS late presentation and its associated factors in China from 2010 to 2020: a systematic review and meta-analysis

BACKGROUND

Late presentation to HIV/AIDS care presents serious health concerns, like increased transmission and high healthcare costs, increased mortality, early development of opportunistic infection, increased risk of antiretroviral therapy drug resistance. Despite the effort to contain the HIV/AIDS epidemic, LP has remained an impediment to individual immune reconstitution and public health.

OBJECTIVE

This review aimed to estimate the prevalence and determine the factors associated with late presentation to HIV/AIDS care.

METHODS

We searched PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese Wanfang, and Weipu database for articles published from 2010 to 2020. We utilized I2 statistics and Q-test to estimate heterogeneity between studies. Random-effects meta-analysis models were used to calculate the aggregate odds ratio of late presentation to HIV/AIDS care.

RESULTS

Of 9563 titles and abstracts retrieved, 189 were identified as potentially eligible and 39 fulfilled the inclusion criteria. The pooled prevalence of late presentation to HIV/AIDS care was 43.26%. The major risk factors were patients ≥ 50 years old (OR = 2.19, 95% CI: 1.85-2.58; I2 = 97.44%), married (OR = 1.50, 95% CI: 1.35-1.68; I2 = 96.58%), with heterosexual contact as risk factor for infection (OR = 1.91, 95% CI: 1.73-2.11; I2 = 90.74%) and diagnosed in medical institutions (OR = 2.35,95% CI: 2.11-2.62; I2 = 96.05%). In middle or low HIV prevalence areas, patients ≥ 50 years old (P = 0.01), married (P < 0.01) and diagnosed in medical institutions (P = 0.01) were more likely to be presented late than in high prevalence areas. From 2016-2020, the OR of patients who were married and diagnosed in medical facilities were significantly lower than before (P < 0.01).

CONCLUSION

Patients ≥ 50 years old, married, with heterosexual contact as risk factor for infection, and diagnosed in medical institutions were risk factors of LP. Gender had no significant relationship with LP. In middle or low prevalence areas, patients who were ≥ 50 years old, married, and diagnosed in medical institutions were more likely to be presented late than in other areas. Married patients and those diagnosed in medical institutions after 2015 have a lower risk of LP than before.

Longitudinal analysis of sociodemographic, clinical and therapeutic factors of HIV-infected individuals in Kinshasa at antiretroviral therapy initiation during 2006-2017

Background

The benefits of antiretroviral therapy (ART) underpin the recommendations for the early detection of HIV infection and ART initiation. Late initiation (LI) of antiretroviral therapy compromises the benefits of ART both individually and in the community. Indeed, it promotes the transmission of infection and higher HIV-related morbidity and mortality with complicated and costly clinical management.

This study aims to analyze the evolutionary trends in the median CD4 count, the median time to initiation of ART, the proportion of patients with advanced HIV disease at the initiation of ART between 2006 and 2017 and their factors.

Methods and findings

HIV-positive adults (≥ 16 years old) who initiated ART between January 1, 2006 and December 31, 2017 in 25 HIV care facilities in Kinshasa, the capital of DRC, were eligible. The data were processed anonymously. LI is defined as CD4≤350 cells/μl and/or WHO clinical stage III or IV and advanced HIV disease (AHD), as CD4≤200 cells/μl and/or stage WHO clinic IV. Factors associated with advanced HIV disease at ART initiation were analyzed, irrespective of year of enrollment in HIV care, using logistic regression models.

A total of 7278 patients (55% admitted after 2013) with an average age of 40.9 years were included. The majority were composed of women (71%), highly educated women (68%) and married or widowed women (61%). The median CD4 was 213 cells/μl, 76.7% of patients had CD4≤350 cells/μl, 46.1% had CD4≤200 cells/μl, and 59% of patients were at WHO clinical stages 3 or 4. Men had a more advanced clinical stage (p <0.046) and immunosuppression (p<0.0007) than women.

Overall, 70% of patients started ART late, and 25% had AHD. Between 2006 and 2017, the median CD4 count increased from 190 cells/μl to 331 cells/μl (p<0.0001), and the proportions of patients with LI and AHD decreased from 76% to 47% (p< 0.0001) and from 18.7% to 8.9% (p<0.0001), respectively.

The median time to initiation of ART after screening for HIV infection decreased from 40 to zero months (p<0.0001), and the proportion of time to initiation of ART in the month increased from 39 to 93.3% (p<0.0001) in the same period.

The probability of LI of ART was higher in married couples (OR: 1.7; 95% CI: 1.3–2.3) (p<0.0007) and lower in patients with higher education (OR: 0.74; 95% CI: 0.64–0.86) (p<0.0001).

Conclusion

Despite increasingly rapid treatment, the proportions of LI and AHD remain high. New approaches to early detection, the first condition for early ART and a key to ending the HIV epidemic, such as home and work HIV testing, HIV self-testing and screening at the point of service, must be implemented.

Characteristics and Sexual Risk Behavior of Men Who Never Tested for HIV in Zambia

Compared with women and girls, proportionately fewer men and boys in sub-Saharan Africa receive HIV testing, treatment, and other services. This study determined factors associated with never testing for HIV and examined never testing as a predictor of sexual risk behavior among men in Zambia. The sample included 2,609 men aged 15 to 24 from the 2018 Zambia Demographic and Health Survey. Logistic regression results revealed that compared with men who ever tested for HIV, men who never tested were more likely to be younger, have less education, have no children, be unemployed, and belong to the low wealth bracket. They also had a higher likelihood of not using a condom at last sex but were less likely to have more than five lifetime sexual partners. HIV prevention programs can use sociodemographic characteristics to identify those who have a lower likelihood of testing for HIV. Prevention programs can use sociodemographic characteristics to develop profiles of those who may especially need to be targeted by initiatives to promote HIV testing. Awareness does not always engender behavior change; therefore, in addition to knowledge of HIV status, risk reduction should also be emphasized.

Bayesian validation framework for dynamic epidemic models

Complex models of infectious diseases are used to understand the transmission dynamics of the disease, project the course of an epidemic, predict the effect of interventions and/or provide information for power calculations of community level intervention studies. However, there have been relatively few opportunities to rigorously evaluate the predictions of such models till now. Indeed, while there is a large literature on calibration (fitting model parameters) and validation (comparing model outputs to data) of complex models based on empirical data, the lack of uniformity in accepted criteria for such procedures for models of infectious diseases has led to simple procedures being prevalent for such steps. However, recently, several community level randomized trials of combination HIV intervention have been planned and/or initiated, and in each case, significant epidemic modeling efforts were conducted during trial planning which were integral to the design of these trials. The existence of these models and the (anticipated) availability of results from the related trials, provide a unique opportunity to evaluate the models and their usefulness in trial design. In this project, we outline a framework for evaluating the predictions of complex epidemiological models and describe experiments that can be used to test their predictions.

Systematic review of research focused on pregnant and postpartum women living with HIV: A relational ethics perspective

Historically, maternal HIV research has focused on prevention of mother-to-child transmission and child outcomes, with little focus on the health outcomes of mothers. Over the course of the HIV epidemic, the approach to including pregnant women in research has shifted. The current landscape lends itself to reviewing the public health ethics of this research. This systematic review aims to identify ethical barriers and considerations for including pregnant and postpartum women living with HIV in treatment adherence and retention research. We completed a systematic literature review following PRISMA guidelines with analysis using a relational ethics perspective. The included studies (n = 7) identified ethical barriers related to (a) women research participants as individuals, (b) partner and family dynamics, (c) community perspectives on research design and conduct, and (d) policy and regulatory implications. These broader contextual factors will yield research responsive to, and respectful of, the needs of pregnant and postpartum women living with HIV. While current regulatory and policy environments may be slow to change, actions can be taken now to foster enabling environments for research. We suggest that a relational approach to public health ethics can best support the needs of pregnant and postpartum women living with HIV; acknowledging this population as systematically disadvantaged and inseparable from their communities will best support the health of this population.

Yathu Yathu ("For us, by us"): Design of a cluster-randomised trial of the impact of community-based, peer-led comprehensive sexual and reproductive health services for adolescents and young people aged 15 to 24 in Lusaka, Zambia

BACKGROUND

In sub-Saharan Africa, the growing population of adolescents and young people aged 15 to 24 face a high burden of HIV, and other preventable and treatable sexually transmitted infections. Despite this burden, adolescents and young people are the population least served by available sexual and reproductive (SRH) services. This trial aims to evaluate the impact of community-based peer-led SRH services, combined with a novel incentivised "loyalty card" system, on knowledge of HIV status and coverage of SRH services.

METHODS

A cluster-randomised trial (CRT) with embedded process and economic evaluation.

DISCUSSION

With little available evidence of the impact of community-based, peer-led services on coverage of SRH services, our study will provide evidence critical to expanding our knowledge of how to reach adolescents and young people. The "loyalty card" system is also a novel approach to providing SRH services. The delivery of community-based services supported by incentives in the form of loyalty cards is innovative, and may prove a simple strategy to improve access to SRH services. Adolescents and young people remain underserved by available SRH services; there remains a critical need to identify ways to provide adolescents and young people with access to SRH services. Rigorous evidence of whether this innovative strategy, with strong links to the local health facility, increases coverage of critical SRH services would add to the evidence-base of how to reach adolescents and young people.

Systems Analysis to Increase HIV Testing Delivery and HIV Diagnosis in Primary Care Clinics in South Africa

BACKGROUND

Provider-initiated testing and counseling remains highly underused in many South African health facilities. We implemented a systems analysis to investigate whether simple adjustments to HIV testing services (HTS) delivery can increase HTS provision.

SETTING

Ten primary care facilities in the Ekurhuleni District in South Africa.

METHODS

Following a baseline HTS assessment that showed limited offering of HTS by clinicians, clinic staff had the option to adopt several change approaches to increase HTS delivery using existing human resources. Approaches included adjusting HTS timing, strengthening HTS promotion, counsellor management, and implementing reward systems. Evaluation was conducted identically to the baseline study using patient exit interviews to quantify HTS engagement and value stream mapping to map patient flow through the clinic.

RESULTS

We conducted 2163 exit interviews and followed 352 patients for value stream mapping. After change implementation, a significantly higher proportion of patients reported being offered HTS (742/2163, 34.3% vs. 231/2206, 10.5% during the baseline period; χ2P < 0.001) and having undertaken testing (527/2163, 24.4% vs. 197/2206, 8.9% during the baseline period; χ2P < 0.001) with only a 3-percentage point decrease in HIV-positive yield (14.0% vs. 17.1% during the baseline period). The median time to HTS offer decreased from 77 minutes to 3 minutes after clinic arrival during the intervention (χ2P = 0.001).

CONCLUSIONS

A systems approach can be an effective and appropriate implementation strategy to augment HTS delivery and increase HIV diagnoses. This low-cost approach may be extended to optimize other aspects of clinic service delivery.

Recognition and management of clinically significant drug-drug interactions between antiretrovirals and co-medications in a cohort of people living with HIV in rural Tanzania: a prospective questionnaire-based study

BACKGROUND

The extent to which drug-drug interactions (DDIs) between antiretrovirals (ARVs) and co-medications are recognized and managed has not been thoroughly evaluated in limited-resource settings.

OBJECTIVES

This prospective questionnaire-based study aimed to determine the prevalence and risk factors for unrecognized/incorrectly managed DDIs in people living with HIV followed-up at the Chronic Diseases Clinic of Ifakara (CDCI) and enrolled in the Kilombero and Ulanga Antiretroviral Cohort (KIULARCO).

METHODS

We prospectively included ARV-treated adults receiving ≥1 co-medication coming for a follow-up visit at the CDCI between March and July 2017. Using a structured questionnaire, physicians were requested to identify potentially clinically significant DDIs in the prescribed treatment, to provide recommendations for their management and to indicate any hurdles to implement the recommendations. Prescriptions were subsequently screened for DDIs using the Liverpool DDIs database. Identified clinically significant DDIs and their recommended management according to the DDIs database were compared with the information provided in the questionnaires.

RESULTS

Among 334 participants, the median age was 47 years (IQR = 40-56 years), 69% were female and 82% had ≥1 non-communicable disease (NCD). Overall, 129 participants had ≥1 clinically relevant DDI, which was not recognized and/or incorrectly managed in 56 participants (43%). Of those, 6 (11%) were due to limited monitoring options or medication affordability issues. In the multivariable logistic regression, the presence of ≥1 NCD was associated with an increased risk for unrecognized/incorrect DDI management (OR = 15.8; 95% CI = 1.8-139.6).

CONCLUSIONS

Recognition/appropriate management of DDIs is suboptimal, highlighting the need for educational programmes, pharmacovigilance activities and increased access to medications and monitoring options. This should become a focus of HIV programmes given the increasing burden of NCDs in sub-Saharan Africa.
