Progress towards the UNAIDS 90-90-90 goals by age and gender in a rural area of KwaZulu-Natal, South Africa: a household-based community cross-sectional survey

The HIV Care Cascade for Older Adults in Rural South Africa: A Longitudinal Cohort Study (2014-2019)

BACKGROUND

As people with HIV grow older, stable engagement in care is essential for healthy aging. We evaluate the HIV care cascade for older adults in rural South Africa at 2 time points cross-sectionally and assess movement in the cascade over time.

SETTING

We evaluated the cascade stage at waves 1 (2014-2015) and 2 (2018-2019) of Health and Aging in Africa: A Longitudinal Study of an INDPETH Community in South Africa, a population-based longitudinal cohort study in Mpumalanga Province, South Africa.

METHODS

Biomarker screening defined cascade stages [HIV+/no antiretroviral therapy (ART); ART+/unsuppressed viral load; ART+/suppressed viral load]. Between-wave probability of death, cascade progression, regression, cascade transitions, and sociodemographic predictors were assessed with Poisson regression. The impact of death was considered using the Fine and Gray competing risk model.

RESULTS

We observed a higher prevalence of antiretroviral therapy with viral suppression over time (50% in wave 1 vs. 70% in wave 2). Among those alive, the oldest age group (70+ years old) was most likely to have cascade progression [adjusted risk ratio for treatment initiation vs. 40-49 years old: 1.38 (95% confidence interval: 1.02 to 1.86)]. However, there was a significant risk of death and cascade regression. Death between waves reached 40% for 70+-year-olds who were ART+/unsuppressed. In competing risk models, older age was associated with equivalent or less cascade progression.

CONCLUSION

Older age groups who were unsuppressed on treatment and men had poorer cascade outcomes. Improvements observed in HIV treatment coverage over time for older adults must be interpreted in the context of the high risk of death for older HIV-positive adults, especially among those failing treatment.

Linkage to HIV care and early retention in HIV care among men in the 'universal test-and-treat' era in a high HIV-burdened district, KwaZulu-Natal, South Africa

INTRODUCTION

Despite the numerous efforts and initiatives, males with HIV are still less likely than women to receive HIV treatment. Across Sub-Saharan Africa, men are tested, linked, and retained in HIV care at lower rates than women, and South Africa is no exception. This is despite the introduction of the universal test-and-treat (UTT) prevention strategy anticipated to improve the uptake of HIV services. The aim of this study was to investigate linkage to and retention in care rates of an HIV-positive cohort of men in a high HIV prevalence rural district in KwaZulu-Natal province, South Africa.

METHODS

From January 2018 to July 2019, we conducted an observational cohort study in 18 primary health care institutions in the uThukela district. Patient-level survey and clinical data were collected at baseline, 4-months and 12-months, using isiZulu and English REDCap-based questionnaires. We verified data through TIER.Net, Rapid mortality survey (RMS), and the National Health Laboratory Service (NHLS) databases. Data were analyzed using STATA version 15.1, with confidence intervals and p-value of ≤0.05 considered statistically significant.

RESULTS

The study sample consisted of 343 male participants diagnosed with HIV and who reside in uThukela District. The median age was 33 years (interquartile range (IQR): 29-40), and more than half (56%; n = 193) were aged 18-34 years. Almost all participants (99.7%; n = 342) were Black African, with 84.5% (n = 290) being in a romantic relationship. The majority of participants (85%; n = 292) were linked to care within three months of follow-up. Short-term retention in care (≤ 12 months) was 46% (n = 132) among men who were linked to care within three months.

CONCLUSION

While the implementation of the UTT strategy has had positive influence on improving linkage to care, men's access of HIV treatment remains inconsistent and may require additional innovative strategies.

"What if I got rejected by the girl? I would rather stop the pills": barriers and facilitators of adherence to antiretroviral therapy for emerging adults aged 18-29 living with HIV in Zimbabwe

Emerging adults aged 18-29 have high rates of viral non-suppression, and poorer adherence to ART when compared to older adults. Semi-structured interviews were conducted with 24 emerging adults in Zimbabwe who had a recent history of viral non-suppression, to explore barriers and facilitators of adherence to ART. Interviews were coded using inductive thematic analysis. The mean age of participants was 23, 65% were male, and 79% reported acquiring HIV at birth. Twelve barriers to adherence were identified. Hiding HIV status due to the possible negative consequences of disclosure had a significant impact on adherence to ART. This was particularly important for emerging adults navigating starting intimate relationships. Being away from home, poverty, poor mental health, isolation, significant life events, alcohol, health systems barriers, and stigma were reported as barriers to adherence. Support from peers and family after disclosure of HIV status, phone-based reminders, problem-solving strategies to adhere, knowing others living with HIV, acted as facilitators to adherence to ART. Beliefs about medicines and relationships with health care providers acted as both barriers and facilitators to adherence. Interventions to reduce stigma, foster peer support, and therapy for common mental disorders could facilitate emerging adults aged 18-29 to adhere to ART.

"It's already in your body and it's preventing": a qualitative study of African female adolescent's acceptability and preferences for proxy HIV prevention methods in Cape Town, South Africa

BACKGROUND

Advances in biomedical HIV prevention will soon offer young women a choice of HIV prevention methods, including various pre-exposure prophylaxis (PrEP) modalities such as daily oral pills, dapivirine vaginal ring, and long-acting injectable agents. By understanding preferences for contraceptive methods, we may draw analogies for the HIV prevention needs of young women. The UChoose Study was an open-label randomised cross-over study designed to evaluate the acceptability and preference for several contraceptive options as a proxy for HIV prevention methods that use similar types of administration. The study enrolled healthy HIV uninfected young women aged 15 to 19 years. At enrolment, participants were randomly assigned to a contraceptive method for a period of 16 weeks in the form of monthly Nuvaring® (vaginal ring), daily combined oral contraceptive (daily pills), or bi-monthly injectable contraceptive (injectable). After 16 weeks, participants crossed over to another contraceptive method, and those who had received the injectable and the daily pills received the vaginal ring for another 16 weeks, whereas those who had received the vaginal ring were able to choose between the injectable and daily pills, to ensure that all participants tried the vaginal ring-the least familiar option to the study population.

RESULTS

Thirty-three participants were purposively recruited to participate in seven focus group discussions (FGD) and completed a pre-survey for their assigned group. Our sample comprised 14 participants randomised to use of the vaginal ring and daily pills and 19 participants randomised to use of the vaginal ring and injectable. For most participants, their preferences for a prevention method were based primarily on their desire to avoid negative aspects of one method rather than their positive user experience with another method. Most participants expressed initial hesitancy for trying new contraception method products; however, a lack of familiarity was moderated by a strong interest in diverse user-controlled prevention methods. Participants valued methods that had infrequent dosing and simplified use requirements. The injection and vaginal ring were preferred over daily pills as a potential HIV prevention method.

CONCLUSION

Expanding the availability of diverse products could provide adolescents with multiple choices in HIV prevention for the uninitiated.

Physical activity and survival in chronic comorbidity among adult HIV patients in Ethiopia: a prospective cohort study

BACKGROUND

Antiretroviral therapy enables people living with HIV to live long lives, and these advances have transformed HIV infection from an acute to a chronic disease. Many non-communicable diseases, including type 2 diabetes, heart disease, and stroke, are influenced by physical inactivity. Therefore, the aim of this study was to assess the level of physical activity and survival in chronic co-morbidity among adult people living with HIV in Ethiopia.

METHODS

An institution-based prospective cohort study of adult people living with HIV was conducted between 2019 and 2021. We included 422 people living with HIV at baseline. After the baseline visit, 364 patients without hypertension or diabetes, were followed up for two years. Nine trained nurses used a pre-tested, structured questionnaire to collect data during routine care consultations in three hospitals in southern Ethiopia. STATA version 15 was used to analyze the data. To estimate the survival probability of developing chronic comorbidities, a Kaplan-Meier survival curve was used. A Cox proportional hazards model was fitted to identify the predictors of the development of chronic comorbidities.

RESULT

In the current study, 39% of the participants were found to have a low level of physical activity. Those who had self-management skills to maintain physical activity (p = 0.023), considered physical activity an important aspect of their HIV management (p = 0.003), and regularly attended social support groups (p = 0.002) had significantly higher levels of physical activity. The risk of chronic comorbidity increased over time, with a rate of 10.83 chronic comorbidities per 1000 persons per month. Lack of regular exercise [AHR: 2.04; 95% CI: (1.03, 5.13)], low physical activity [AHR: 2.01; 95% CI: (1.03, 7.89)], BMI greater than 25 kg/m2 [AHR: 2.74; 95% CI: (1.31, 5.12)] and low fruit and vegetable intake [AHR = 2.57; 95% CI: (1.28, 6.49)] were all associated with the development of chronic comorbidity.

CONCLUSION

The prevalence of physical inactivity is high in the study population. A physical activity program for people living with HIV should be considered, and the promotion of self-management skills should be integrated into HIV care programs.

Evidence of HIV incidence reduction in young women, but not in adolescent girls, in KwaZulu-Natal, South Africa

Objectives

We estimated changes in the HIV incidence from 2013-2018 in Eshowe/Mbongolwane, KwaZulu-Natal, South Africa where Médecins Sans Frontières is engaged in providing HIV testing and care since 2011.

Methods

Using data from two cross-sectional household-based surveys conducted in 2013 and 2018, with consenting participants aged 15-59 years, we applied the incidence estimation frameworks of Mahiane et al and Kassanjee et al.

Results

In total, 5599 (62.4% women) and 3276 (65.9% women) individuals were included in 2013 and 2018, respectively. We found a mean incidence in women aged 20-29 years of 2.71 cases per 100 person-years (95% confidence interval [CI]: 1.23;4.19) in 2013 and 0.4 cases per 100 person-years (95% CI: 0.0;1.5) in 2018. The incidence in men aged 20-29 years was 1.91 cases per 100 person-years (95% CI: 0.87; 2.93) in 2013 and 0.53 cases per 100 person-years (95% CI: 0.0; 1.4) in 2018. The incidence decline among women aged 15-19 was -0.34 cases per 100 person-years (95% CI: -1.31;0.64).

Conclusions

The lack of evidence of incidence decline among adolescent girls is noteworthy and disconcerting. Our findings suggest that large-scale surveys should seriously consider focusing their resources on the core group of women aged 15-19 years.

Trends in HIV prevalence, incidence, and progress towards the UNAIDS 95-95-95 targets in Malawi among individuals aged 15-64 years: population-based HIV impact assessments, 2015-16 and 2020-21

BACKGROUND

In 2014, UNAIDS set the goal of ending the AIDS epidemic by 2030 through the achievement of testing and treatment cascade targets. To evaluate progress achieved and highlight persisting gaps in HIV epidemic control in Malawi, we aimed to compare key indicators (prevalence, incidence, viral load suppression, and UNAIDS 95-95-95 targets) from the 2015-16 and 2020-21 Malawi Population-based HIV Impact Assessment (PHIA) survey results.

METHODS

The Malawi PHIAs were nationally representative, cross-sectional surveys with a two-stage cluster sampling design. The first survey was conducted between Nov 27, 2015, and Aug 26, 2016; the second survey was conducted between Jan 15, 2020, and April 26, 2021. Our analysis included survey participants aged 15-64 years. Participants were interviewed and a 14 mL blood sample was collected and tested for HIV infection using the national rapid testing algorithm. For each survey, we estimated key HIV epidemic indicators and achievement of 95-95-95 targets. The risk ratio (RR) of the indicators between surveys were computed and considered significant at a confidence level of 0·05. All results were weighted, and self-reported awareness and treatment status were adjusted to account for detection of antiretrovirals.

FINDINGS

Our analysis included 17 187 participants aged 15-64 years in 2015-16 and 21 208 in 2020-21 who participated in the surveys and blood draw. In the 2020-21 survey, 88·4% (95% CI 86·7-90·0) of people living with HIV were aware of their HIV-positive status; of those aware, 97·8% (97·1-98·5) were on antiretroviral therapy; and of those on treatment, 96·9% (95·9-97·7) were virally suppressed. Between surveys, the national HIV prevalence decreased significantly from 10·6% (10·0-11·2) to 8·9% (8·4-9·5) with RR 0·85 (95% CI 0·78-0·92; p<0·0001). The annual HIV incidence decreased from 0·37% (0·20-0·53) to 0·22% (0·11-0·34) with RR 0·61 (95% CI 0·31-1·20; p=0·15). The population viral load suppression increased from 68·3% (66·0-70·7) in 2015-16 to 87·0% (85·3-88·5) in 2020-21 (RR 1·27 [95% CI 1·22-1·32]; p<0·0001).

INTERPRETATION

These results suggest that Malawi had already surpassed the UNAIDS viral load suppression target for 2030 (85·7%) by 2020-21. Through strategies and evidence-informed interventions implemented in the last half decade, especially scale-up of effective HIV treatment, Malawi has made tremendous progress, including decreasing HIV prevalence and incidence and achieving both the second and third 95 targets ahead of 2030. To address the first 95, efforts in HIV diagnosis should focus on males and younger age groups. There is a continued need for effective linkage to care, retention on antiretroviral therapy, and adherence support to maintain and build on progress.

HIV Related Behaviors Among Male Partners of Adolescent Girls and Young Women in Rural South Africa

Improving men's engagement in HIV prevention is not only essential for reducing their own HIV risk but also the risk of transmitting HIV to their female partners. We conducted a cross-sectional survey using a population-based sample of men (age 18-30) who reported being a partner of an adolescent girls and young women (AGYW) in South Africa (N = 2827). We used logit-binomial regression models to examine associations among men's partnership characteristics, HIV risk perceptions, and HIV-related behaviors and examine differences by male partner age (younger men (18-24) vs. older men (25-30)) and age difference between partners (age-concordant (< 5 years) vs. age-disparate (≥ 5 years)). Most men reported inconsistent condom use (85%) and nearly half reported engaging in transactional sex (48%). Older men were just as likely as younger men, and men with age-disparate and age-concordant partners, to inconsistently use condoms, engage in transactional sex, and perpetrate intimate partner violence. Most men also reported a very high interest in pre-exposure prophylaxis (PrEP) (77%) and half reported having an HIV test in the past year (50%). There were no differences by male partner age or age difference between partners in PrEP interest but older men and men in age-discordant relationships were more likely than younger men and men in age-concordant relationships to have an HIV test in the past year. Male partners of AGYW in South Africa are engaging in HIV-related behaviors and need HIV prevention interventions to reduce risk for themselves and their female partners.

Retention on ART and viral suppression among patients in alternative models of differentiated HIV service delivery in KwaZulu-Natal, South Africa

Differentiated models of HIV care (DMOC) aim to improve health care efficiency. We describe outcomes of five DMOC in KwaZulu-Natal, South Africa: facility adherence clubs (facility AC) and community adherence clubs (community AC), community antiretroviral treatment (ART) groups (CAG), spaced fast lane appointments (SFLA), and community pick up points (PuP). This retrospective cohort study included 8241 eligible patients enrolled into DMOC between 1/1/2012 and 31/12/2018. We assessed retention in DMOC and on ART, and viral load suppression (<1000 copies/mL). Kaplan-Meier techniques were applied to describe crude retention. Mixed effects parametric survival models with Weibull distribution and clustering on health center and individual levels were used to assess predictors for ART and DMOC attrition, and VL rebound (≥1000 copies/mL). Overall DMOC retention was 85%, 80%, and 76% at 12, 24 and 36 months. ART retention at 12, 24 and 36 months was 96%, 93%, 90%. Overall incidence rate of VL rebound was 1.9 episodes per 100 person-years. VL rebound rate was 4.9 episodes per 100 person-years among those enrolled in 2012-2015, and 0.8 episodes per 100 person-years among those enrolled in 2016-2018 (RR 0.12; 95% CI, 0.09-0.15, p<0.001). Prevalence of confirmed virological failure was 0.6% (38/6113). Predictors of attrition from DMOC and from ART were male gender, younger age, shorter duration on ART before enrollment. Low level viremia (>200-399 copies/mL) was associated with higher hazards of VL rebound and attrition from ART. Concurrent implementation of several DMOC in a large ART program is feasible and can achieve sustained retention on ART and VL suppression.

Incentives to promote accessing HIV care and viral suppression among HIV self-screening test users who obtain a reactive result

Introduction

Achieving viral suppression in people with HIV is crucial in ending the AIDS epidemic. Among users of HIV self-screening tests, low rates of linkage to care and early retention in care are key obstacles to achieving viral suppression. This study sought to evaluate the efficacy of financial incentives in supporting HIV case management.

Methods

Young adults within the inner city of Johannesburg, South Africa and surrounding areas who used HIV self-tests, were able to use WhatsApp to communicate with study personnel, reported a reactive or invalid result, and were confirmed to by HIV-positive were enrolled in the study. Participants were randomised to an intervention arm that received reminders and financial rewards for engaging in care, or to a control arm that received the standard of care. The primary outcome was HIV viral load at six months.

Results

Among 2,388 HIV self-test kits that were distributed, 1757/2,388 (73,58%) recipients were able to use their phones to send photos to study personnel. 142/1,757 (8,08%) of these recipients reported reactive or invalid results. Upon confirmatory testing, 99/142 (69,71%) participants were identified as being HIV-positive and were enrolled in the study. 2 (1,41%) participants received an HIV negative result, and 41(28,87%) participants were either lost to follow-up or did not complete the confirmatory testing step. 20/99 (20,2%) from the intervention arm and 18/99 (18,18%) from the control arm completed the study (i.e., attended a 6 month follow up and participated in the exit interview). 29/99 (29,29%) were virally suppressed by at 6 months. Of those achieving viral suppression 15 (51,72%) were from the intervention arm.

Conclusion

Financial incentives and reminders were not effective in promoting engagement with HIV care and viral suppression in this setting.

Kharsany A, Zewotir T, North D. Spatial Variation and Factors Associated with Unsuppressed HIV Viral Load among Women in an HIV Hyperendemic Area of KwaZulu-Natal, South Africa

New HIV infections among young women remains exceptionally high and to prevent onward transmission, UNAIDS set ambitious treatment targets. This study aimed to determine the prevalence, spatial variation and factors associated with unsuppressed HIV viral load at ≥400 copies per mL. This study analysed data from women aged 15–49 years from the HIV Incidence Provincial Surveillance System (HIPSS) enrolled in two sequential cross-sectional studies undertaken in 2014 and 2015 in rural and peri-urban KwaZulu-Natal, South Africa. Bayesian geoadditive model with spatial effect for a small enumeration area was adopted using Integrated Nested Laplace Approximation (INLA) function to analyze the findings. The overall prevalence of unsuppressed HIV viral load was 45.2% in 2014 and 38.1% in 2015. Factors associated with unsuppressed viral load were no prior knowledge of HIV status, had a moderate-to-low perception of acquiring HIV, not on antiretroviral therapy (ART), and having a low CD4 cell count. In 2014, women who ever consumed alcohol and in 2015, ever ran out of money, had two or more lifetime sexual partners, ever tested for tuberculosis, and ever diagnosed with sexually transmitted infection were at higher risk of being virally unsuppressed. The nonlinear effect showed that women aged 15 to 29 years, from smaller households and had fewer number of lifetime HIV tests, were more likely to be virally unsuppressed. High viral load risk areas were the north-east and south-west in 2014, with north and west in 2015. The findings provide guidance on identifying key populations and areas for targeted interventions.

Viral suppression among pregnant adolescents and women living with HIV in rural KwaZulu-Natal, South Africa: a cross sectional study to assess progress towards UNAIDS indicators and Implications for HIV Epidemic Control

BACKGROUND

South Africa has made significant progress in scaling up antiretroviral therapy (ART) to achieve the aspirational goal of HIV epidemic control. The aim of this study was to determine the prevalence of HIV, assess progress towards each of the Joint United Nations Programme on HIV/AIDS (UNAIDS) indicators and determine factors associated with achieving viral suppression among pregnant adolescents and women living with HIV in rural KwaZulu-Natal, South Africa.

METHODS

Pregnant adolescents and women, 12 years and older seeking antenatal care at six primary health care clinics were enrolled in a cross-sectional study. Following written informed consent, structured questionnaires were administered, and finger-prick blood samples were collected for HIV antibody testing and viral load measurement. Viral suppression was defined as HIV viral load of < 400 copies per mL.

RESULTS

Between Dec 2016 and March 2017, among the 546 enrolled participants, data for 545 were analysed. The overall HIV prevalence was 40.2% [95% Confidence Interval (CI) 36.1-44.3]. Age-stratified prevalence increased from 22.1% (95% CI, 15.9-30.0) in the 14-19 year age group to 63.9% (95% CI, 55.1-71.9) among women ≥ 30 years (Χ2 trend P < 0.0001). Of the HIV positive participants, 84.5% (95% CI, 79.0-88.8) knew their HIV positive status, 98.3% (95% CI 95.1-99.4) who knew their status were on ART, and of those on ART, 95.9% (95% CI 91.8-98.0) were virally suppressed. Among all HIV-positives 90.8% (95% CI, 86.3-94.0) had achieved viral suppression, whilst those in the 14-19 year age group were least likely to be virally suppressed at 82.8% (95% CI 65.5-92.4) compared to those in the older age groups. Married women compared to those unmarried were more likely to have achieved viral suppression (PRR) of 1.11 (95% CI 1.05-1.18), P < 0.001.

CONCLUSIONS

The proportion of HIV positive pregnant women achieving viral suppression was encouraging though far short of the target towards achieving epidemic control. Importantly, adolescent pregnant women were less likely to know their HIV status and to achieve viral suppression, underscoring the public health implications of sustained risk of HIV transmission. Thus, greater effort and strong social support are essential to improve HIV knowledge of status and care continuum towards the goal to achieving HIV epidemic control. To "fast-track" the response to achieve HIV epidemic control and end the AIDS epidemic, the Joint United Nations Programme on HIV/AIDS (UNAIDS) set ambitious HIV testing and treatment targets for people living with HIV. Meeting these targets through scaling up testing for HIV, initiating and sustaining antiretroviral therapy (ART) to maintain viral suppression provides both therapeutic and preventive benefits with the potential to reduce HIV transmission. Viral suppression among pregnant adolescents and women living with HIV is crucial for the prevention of mother-to-child transmission of HIV including onward transmission to sexual partners. As a public health approach, in South Africa all pregnant women are offered routine HIV testing and immediate initiation of lifelong ART irrespective of CD4 cell count. It is, therefore, important to ascertain progress towards reaching the targets. The proportion of HIV positive pregnant adolescents and women achieving viral suppression was encouraging though far short of the target towards achieving epidemic control. Importantly, pregnant adolescents were less likely to know their HIV status and to achieve viral suppression, underscoring the public health implications of sustained risk of HIV transmission. Thus, greater effort and strong social support are essential to improve HIV knowledge of status and care continuum towards the goal to achieving HIV epidemic control.

Development of a Bead-Based Multiplex Assay for Use in Multianalyte Screening and Surveillance of HIV, Viral Hepatitis, Syphilis, and Herpes

Diagnostic assays that can simultaneously determine the presence of infection with multiple pathogens are key for diagnosis and surveillance. Current multiplex diagnostic assays are complex and often have limited availability. We developed a simple, multianalyte, pathogen detection assay for screening and serosurveillance using the Luminex Magpix platform that is high throughput and can be helpful in monitoring multiple diseases. The Luminex bead-based 10-plex immunoassay for the detection of HIV-1, HIV-2, Treponema pallidum, hepatitis B virus (HBV), hepatitis C virus (HCV), herpes simplex virus 1 (HSV-1), and HSV-2 infections was accomplished by coupling beads with specific antigens to detect IgG antibodies in plasma or serum samples. Each coupled antigen was systematically optimized, and the performance was evaluated using a panel of well-characterized specimens (n = 417) that contained antibodies to HIV-1, HIV-2, T. pallidum, HBV, HCV, HSV-1, and HSV-2. The multiplex assay had a sensitivity of 92.2% (95% Clopper-Pearson confidence interval [CI], 90.2 to 94.0%) and a specificity of 98.1% (95% CI, 97.6 to 98.7%). The sensitivities and specificities for disease-specific biomarker detection ranged from 68.7 to 100% and 95.6 to 100%, respectively. The results showed that the 10-plex immunoassay had an overall agreement of 96.7% (95% CI, 96.7 to 97.3%) with reference tests and a corresponding kappa value of 0.91 (95% CI, 0.90 to 0.93). Kappa values for the individual pathogens ranged from 0.69 to 1.00. The assay is robust and allows the simultaneous detection of antibodies to multiple antigens using a small sample volume in a high-throughput format. This assay has the potential to simplify disease surveillance by providing an alternative to expensive and highly specialized individual tests.

Men missing from the HIV care continuum in sub-Saharan Africa: a meta-analysis and meta-synthesis

Introduction

Men are missing along the HIV care continuum. However, the estimated proportions of men in sub‐Saharan Africa meeting the UNAIDS 95‐95‐95 goals vary substantially between studies. We sought to estimate proportions of men meeting each of the 95‐95‐95 goals across studies in sub‐Saharan Africa, describe heterogeneity, and summarize qualitative evidence on factors influencing care engagement.

Methods

We systematically searched PubMed and Embase for peer‐reviewed articles published between 1 January 2014 and 16 October 2020. We included studies involving men ≥15 years old, with data from 2009 onward, reporting on at least one 95‐95‐95 goal in sub‐Saharan Africa. We estimated pooled proportions of men meeting these goals using DerSimonion‐Laird random effects models, stratifying by study population (e.g. studies focusing exclusively on men who have sex with men vs. studies that did not), facility setting (healthcare vs. community site), region (eastern/southern Africa vs. western/central Africa), outcome measurement (e.g. threshold for viral load suppression), median year of data collection (before vs. during or after 2017) and quality criteria. Data from qualitative studies exploring barriers to men's HIV care engagement were summarized using meta‐synthesis.

Results and discussion

We screened 14,896 studies and included 129 studies in the meta‐analysis, compiling data over the data collection period. Forty‐seven studies reported data on knowledge of serostatus, 43 studies reported on antiretroviral therapy use and 74 studies reported on viral suppression. Approximately half of men with HIV reported not knowing their status (0.49 [95% CI, 0.41–0.58; range, 0.09–0.97]) or not being on treatment (0.58 [95% CI, 0.51–0.65; range, 0.07–0.97]), while over three‐quarters of men achieved viral suppression on treatment (0.79 [95% CI, 0.77–0.81; range, 0.39–0.97]. Heterogeneity was high, with variation in estimates across study populations, settings and outcomes. The meta‐synthesis of 40 studies identified three primary domains in which men described risks associated with engagement in HIV care: perceived social norms, health system challenges and poverty.

Conclusions

Psychosocial and systems‐level interventions that change men's perceptions of social norms, improve trust in and accessibility of the health system, and address costs of accessing care are needed to better engage men, especially in HIV testing and treatment.

Increase in HIV viral suppression in KwaZulu-Natal, South Africa: Community-based cross sectional surveys 2018 and 2013. What remains to be done?

INTRODUCTION

High coverage of antiretroviral therapy (ART) in people living with HIV (PLHIV) increases viral suppression at population level and may reduce incidence. Médecins sans Frontières, in collaboration with the South African Department of Health, has been working in Eshowe/Mbongolwane (KwaZulu Natal) since 2011 to increase access to quality HIV services. Five years after an initial survey, we conducted a second survey to measure progress in HIV diagnosis and viral suppression and to identify remaining gaps.

METHODS

A cross-sectional, population-based, stratified two-stage cluster survey was implemented in 2018, using the same design as in 2013. Consenting participants aged 15-59 years were interviewed and tested for HIV at home. Those HIV-positive were tested for HIV viral load (viral suppression defined as <1000 copies/mL).

RESULTS

Overall, 3,278 individuals were included. The proportion of HIV-positive participants virally suppressed was 83.8% in 2018 compared to 57.1% in 2013 (p<0.001), with increases in all subpopulations. The largest gap remained in men aged 15-29 years, among whom viral suppression was 51.5%. Nevertheless, of the total unsuppressed participants, 60.3% were women, and 57.4% were individuals aged 30-59 years. Between 2013 and 2018, HIV-positive status awareness progressed from 75.2% to 89.9% and ART coverage among those aware from 70.4% to 93.8%, respectively. Among those on ART, 94.5% were virally suppressed in 2018.

CONCLUSIONS

Viral suppression improved significantly from 2013 to 2018, in all age and gender groups of PLHIV. However, almost half of HIV-positive young men remained unsuppressed, while the majority of virally unsuppressed PLHIV were women and older adults. To continue lowering HIV transmission, specific strategies are needed to increase viral suppression in those groups.

Post-Immune Antibodies in HIV-1 Infection in the Context of Vaccine Development: A Variety of Biological Functions and Catalytic Activities

Unlike many other viruses, HIV-1 is highly variable. The structure of the viral envelope changes as the infection progresses and is one of the biggest obstacles in developing an HIV-1 vaccine. HIV-1 infection can cause the production of various natural autoantibodies, including catalytic antibodies hydrolyzing DNA, myelin basic protein, histones, HIV-integrase, HIV-reverse transcriptase, β-casein, serum albumin, and some other natural substrates. Currently, there are various directions for the development of HIV-1 vaccines: stimulation of the immune response on the mucous membranes; induction of cytotoxic T cells, which lyse infected cells and hold back HIV-infection; immunization with recombinant Env proteins or vectors encoding Env; mRNA-based vaccines and some others. However, despite many attempts to develop an HIV-1 vaccine, none have been successful. Here we review the entire spectrum of antibodies found in HIV-infected patients, including neutralizing antibodies specific to various viral epitopes, as well as antibodies formed against various autoantigens, catalytic antibodies against autoantigens, and some viral proteins. We consider various promising targets for developing a vaccine that will not produce unwanted antibodies in vaccinated patients. In addition, we review common problems in the development of a vaccine against HIV-1.

Uptake and Short-Term Retention in HIV Treatment Among Men in South Africa: The Coach Mpilo Pilot Project

In this pilot project, providing peer support to men living with HIV retained a high proportion of men living with HIV in the early stages of HIV treatment and successfully supported men in returning to care after a treatment interruption.

Introduction:

Gender disparities persist across the HIV care continuum in sub-Saharan Africa. Men are tested, linked, and retained at lower rates than women. Men experience more treatment interruptions, resulting in higher rates of virological failure and increased mortality. Peer support is an approach to improving men’s engagement and retention in HIV treatment. We assessed uptake and early retention in HIV care among men in the ‘Coach Mpilo’ peer support pilot project in South Africa.

Methods:

We conducted a pilot project from March 2020 to September 2020 in 3 districts: Ehlanzeni and Gert Sibande (Mpumalanga) and Ugu (KwaZulu-Natal). Men living with HIV were invited to receive one-on-one coaching from a peer supporter who was stable on treatment. We analyzed participants’ self-reported data on demographics, uptake, and retention in HIV treatment. We described baseline characteristics using summary statistics and reported uptake and early retention proportions overall and by testing history (newly and previously diagnosed).

Results:

Among 4,182 men living with HIV, most were previously diagnosed (n=2,461, 64%) and uptake was high (92%, n=3,848). Short-term retention was 80% (n=1,979) among men previously diagnosed and 88% (n=1,213) among newly diagnosed. In September 2020, 95% (n=3,653/3,848) of all participants reported being active on HIV treatment, including those retained consistently and those who had interrupted and returned to care. Among participants experiencing treatment interruption after enrolling, the majority (82%, n=464) returned to treatment, largely within 2 months.

Conclusions:

Improving linkage to and retention in HIV treatment among men is essential for their health and for treatment as prevention. This pilot project provided preliminary evidence that a peer-led support model was acceptable, retained a high proportion of men in the early stages of ART, and supported men returning to care after treatment interruption. These promising results require further investigation to assess impact, scalability, and cost-effectiveness.

Progress towards controlling the HIV epidemic in urban Ethiopia: Findings from the 2017-2018 Ethiopia population-based HIV impact assessment survey

INTRODUCTION

In 2014, the Joint United Nations Programme on HIV/AIDS set an 'ambitious' 90-90-90 target for 2020. By 2016, there were disparities observed among countries in their progress towards the targets and some believed the targets were not achievable. In this report, we present the results of data from the Ethiopia Population-based HIV Impact Assessment survey analyzed to assess progress with the targets and associated factors.

METHODS

We conducted a nationally representative survey in urban areas of Ethiopia. Socio-demographic and behavioural data were collected from consenting participants using a structured interview. HIV testing was done following the national HIV rapid testing algorithm and seropositivity confirmed using a supplemental laboratory assay. HIV viral suppression was considered if the viral load was <1,000 RNA copies/ml. Screening antiretroviral drugs was done for efavirenz, lopinavir, and tenofovir, which were in use during the survey period. In this analysis, we generated weighted descriptive statistics and used bivariate and logistic regression analysis to examine for associations. The 95% confidence interval was used to measure the precision of estimates and the significance level set at p<0.05.

RESULTS

Of 19,136 eligible participants aged 15-64 years, 614 (3% [95% CI: 0.8-3.3]) were HIV-positive, of which 79.0% (95% CI: 4.7-82.7) were aware of their HIV status, and 97.1% (95% CI: 95.0-98.3 were on antiretroviral therapy, of which 87.6% (95% CI: 83.9-90.5) achieved viral load suppression. Awareness about HIV-positive status was significantly higher among females (aOR = 2.8 [95% CI: 1.38-5.51]), significantly increased with age, the odds being highest for those aged 55-64 years (aOR = 11.4 [95% CI: 2.52-51.79]) compared to those 15-24 years, and was significantly higher among those who used condom at last sex in the past 12 months (aOR = 5.1 [95% CI: 1.68-15.25]). Individuals with secondary education and above were more likely to have achieved viral suppression (aOR = 8.2 [95% CI: 1.82-37.07]) compared with those with no education.

CONCLUSION

Ethiopia made encouraging progress towards the UNAIDS 90-90-90 targets. The country needs to intensify its efforts to achieve the targets. A particular focus is required to fill the gaps in knowledge of HIV-positive status to increase case identification among population groups such as males, the youth, and those with low education.

Mental illness and HIV amongst female inmates in Durban, South Africa

BACKGROUND

There is limited data regarding the prevalence of mental illness and human immunodeficiency virus (HIV) amongst female inmates in South Africa. Rehabilitation programmes can only be formulated once the needs of this population have been identified.

AIM

This study aimed to measure the prevalence of mental illnesses, borderline and antisocial personality disorders and HIV amongst female inmates.

SETTING

The study was based at a correctional centre in Durban, KwaZulu-Natal, South Africa.

METHODS

This study forms part of a larger two-phased, mixed methods, sequential, explanatory design study. In phase one, 126 female inmates were interviewed using a clinical questionnaire and the Structured Clinical Interview for Diagnostics and Statistical Manual (DSM)-5 diagnoses - Research Version.

RESULTS

The following lifetime prevalence rates were found: depressive disorder 70.6%, alcohol use disorder 48.4%, post-traumatic stress disorder (PTSD) 46.8%, borderline personality disorder 33.3%, substance use disorder 31.7%, antisocial personality disorder 15.1% and psychotic disorder 4.8%. The prevalence of current adult attention-deficit and hyperactivity disorder was 9.5%. A total of 39% of the participants admitted to past suicide attempts, whilst 64.3% reported past suicidal ideation and 36.5% had a current episode of a psychiatric disorder. A total of 64.3% of the participants were living with HIV. Although 90.4% had a lifetime psychiatric disorder, only 16.7% were previously diagnosed with a mental illness. The majority of inmates with lifetime disorders had psychiatric comorbidities.

CONCLUSION

The high prevalence of mental illness and HIV amongst female inmates, and the fact that most with mental illness remain undiagnosed, is concerning. Improved screening, identification and treatment of mental illnesses in this population is needed to ensure optimal mental health outcomes and decreased recidivism.

Population sizes, HIV prevalence, and HIV prevention among men who paid for sex in sub-Saharan Africa (2000-2020): A meta-analysis of 87 population-based surveys

BACKGROUND

Key populations, including sex workers, are at high risk of HIV acquisition and transmission. Men who pay for sex can contribute to HIV transmission through sexual relationships with both sex workers and their other partners. To characterize the population of men who pay for sex in sub-Saharan Africa (SSA), we analyzed population size, HIV prevalence, and use of HIV prevention and treatment.

METHODS AND FINDINGS

We performed random-effects meta-analyses of population-based surveys conducted in SSA from 2000 to 2020 with information on paid sex by men. We extracted population size, lifetime number of sexual partners, condom use, HIV prevalence, HIV testing, antiretroviral (ARV) use, and viral load suppression (VLS) among sexually active men. We pooled by regions and time periods, and assessed time trends using meta-regressions. We included 87 surveys, totaling over 368,000 male respondents (15-54 years old), from 35 countries representing 95% of men in SSA. Eight percent (95% CI 6%-10%; number of surveys [Ns] = 87) of sexually active men reported ever paying for sex. Condom use at last paid sex increased over time and was 68% (95% CI 64%-71%; Ns = 61) in surveys conducted from 2010 onwards. Men who paid for sex had higher HIV prevalence (prevalence ratio [PR] = 1.50; 95% CI 1.31-1.72; Ns = 52) and were more likely to have ever tested for HIV (PR = 1.14; 95% CI 1.06-1.24; Ns = 81) than men who had not paid for sex. Men living with HIV who paid for sex had similar levels of lifetime HIV testing (PR = 0.96; 95% CI 0.88-1.05; Ns = 18), ARV use (PR = 1.01; 95% CI 0.86-1.18; Ns = 8), and VLS (PR = 1.00; 95% CI 0.86-1.17; Ns = 9) as those living with HIV who did not pay for sex. Study limitations include a reliance on self-report of sensitive behaviors and the small number of surveys with information on ARV use and VLS.

CONCLUSIONS

Paying for sex is prevalent, and men who ever paid for sex were 50% more likely to be living with HIV compared to other men in these 35 countries. Further prevention efforts are needed for this vulnerable population, including improved access to HIV testing and condom use initiatives. Men who pay for sex should be recognized as a priority population for HIV prevention.

Two-fold increase in the HIV viral load suppression rate along with decreased incidence over six years in Ndhiwa sub-county, Kenya

Background

HIV‐positive individuals who maintain an undetectable viral load cannot transmit the virus to others. In 2012, an HIV population‐based survey was conducted in Ndhiwa sub‐county (Kenya) to provide information on the HIV local epidemic. We carried out a second survey 6 years after the first one, to assess progress in HIV diagnosis and care and differences in the HIV prevalence and incidence between the two surveys.

Methods

A cross‐sectional, population‐based survey using cluster sampling and geospatial random selection was implemented in 2018, using the same design as 2012. Consenting participants aged 15–59 years were interviewed and tested for HIV at home. HIV‐positive individuals received viral load testing (viral suppression defined as <1000 copies/ml) and Lag‐Avidity EIA assay (to measure recent infection). The 90–90–90 UNAIDS indicators were also assessed.

Results

Overall, 6029 individuals were included in 2018. HIV prevalence was 16.9%. Viral suppression among all HIV‐positive was 88.3% in 2018 (vs. 39.9% in 2012, p < 0.001). HIV incidence was 0.75% in 2018 vs. 1.90% in 2012 (p = 0.07). In 2018, the 90–90–90 indicators were 93%–97%–95% (vs. 60%–68%–83% in 2012).

Conclusion

A two‐fold increase in the HIV viral load suppression rate along with a decreasing trend in incidence was observed over 6 years in Ndhiwa sub‐county. Achieving high rates of viral suppression in HIV populations that can lead to reducing HIV transmission in sub‐Saharan contexts is feasible. Nevertheless, we will need further efforts to sustain this progress.

Unique and Shared Correlates of Sexual Violence Perpetration and Sexual Risk Behavior Among South African Adolescent Boys

Associations between sexual risk behavior (SRB) and sexual violence perpetration (SVP) contribute to the intersecting HIV and sexual violence epidemics in South Africa. We examined SVP and SRB, and their potential correlates among South African boys (N = 80; ages 15-17). Fifty-one percent endorsed SVP in the past year; 61% engaged in past-3-month SRB. Whereas most unique correlates were socio-structural, family, or community factors, correlates shared across behaviors were behavior-specific social norm perceptions and cognitive factors. In final multivariate models, food insecurity and positive attitudes toward delaying sex were associated with SVP (odds ratios [ORs] = 3.05 and 0.37, respectively), and community violence exposure, gender equitable social norm perceptions, positive attitudes toward delaying sex, and intentions to obtain sexual consent were associated with SRBs (ORs = 1.56-1.57, 0.90-0.38, 0.58-0.60, respectively). Interventions to address HIV/sexual violence risk among adolescents in South Africa should be integrated and multilevel.

Continuum of Care UNAIDS Fast-Track Targets Evaluation of Patients Living with Human Immunodeficiency Virus Infection

The current study evaluated the progress of continuum healthcare for patients living with human immunodeficiency virus (HIV) infection from Cluj County in two moments, 2016 and 2020, and compared the results to the Fast-Track targets (FTTs) proposed by the Joint United Nations Programme (UNAIDS) on HIV/AIDS. By the end of 2020, 368 out of 385 confirmed HIV-positive patients from Cluj County were under surveillance in our center, representing almost 95% of the patients living with HIV and knowing their diagnosis, compared to 87.9% in 2016. Nearly 97% of those in active follow-up from Cluj County were under antiretroviral therapy (ART) in 2020, compared to 89% in 2016. The number of virally suppressed patients from those under ART was almost 94% in 2020, compared to 82.7% in 2016, and the increase is observed regardless of the ART regime. A shift towards integrase strand transfer inhibitors, with a higher efficacy, fewer adverse effects, and fewer drug interactions, is observed, which could contribute to the decrease in HIV transmission.

Disparities between HIV patient subgroups in Oman: An analysis of the 2019 cascade of care

Background

The HIV cascade of care is a framework for monitoring HIV care, identifying gaps and informing appropriate interventions. This study aimed to describe the cascade of care in Oman in 2019 and highlight disparities at the sub-population level.

Methods

We used the UNAIDS Spectrum modelling software to estimate the number of people living with HIV. A national HIV surveillance database was used to identify Omani people (≥13 years old) diagnosed with HIV from 1984 through December 2019. We calculated the cascade indicators as of 31 December 2019 stratified by sex, age, HIV risk factor, residence, and region of HIV care. We also performed multivariate logistic regression to determine the predictors of attrition at linkage, retention, on ART, and viral suppression.

Results

As of December 2019, the estimated number of people living with HIV in Oman was 2440. Out of the estimated number of people living with HIV, 69% were diagnosed, 66% were linked to care, 61% were retained in care, 60% were on ART, and 55% were virally suppressed. Of the 1673 diagnosed individuals, 96% were linked to care, 88% were retained in care, 87% were on ART, and 81% were virally suppressed. People who received HIV care outside Muscat had the largest attrition (11% loss) in the transition from linkage (97%) to retention (86%). Similarly, people aged 13–24 years had the largest attrition (13% loss) from “on ART” (88%) to viral suppression (75%). Logistic regression showed that both not reporting a specific HIV risk factor and receipt of HIV care outside Muscat independently predicted attrition at each cascade stage from linkage to care through viral suppression.

Conclusions

Our findings identified substantial disparities across various subpopulations along the cascade of care in Oman. This analysis will be invaluable in informing future interventions targeting patient subgroups who are at the highest risk of attrition.

Large age shifts in HIV-1 incidence patterns in KwaZulu-Natal, South Africa

HIV incidence has recently been in decline across some of the most intense epidemics in sub-Saharan Africa due to the scale-up of prevention and transmission-blocking treatments. Understanding whether declines in incidence are being felt equally across age and gender can help prioritize demographic groups where more effort is needed to lower transmission. We found that HIV incidence has declined disproportionately in the youngest men and women in a population with the highest HIV prevalence in the world. Shifts in the age distribution of risk may be the consequence of aging prevalence, prioritized prevention to younger individuals, and delays in age at infection from reduced overall force of infection. Our results highlight the need to expand age targets for HIV prevention.

Recent declines in adult HIV-1 incidence have followed the large-scale expansion of antiretroviral therapy and primary HIV prevention across high-burden communities of sub-Saharan Africa. Mathematical modeling suggests that HIV risk will decline disproportionately in younger adult age-groups as interventions scale, concentrating new HIV infections in those >age 25 over time. Yet, no empirical data exist to support these projections. We conducted a population-based cohort study over a 16-y period (2004 to 2019), spanning the early scale-up of antiretroviral therapy and voluntary medical male circumcision, to estimate changes in the age distribution of HIV incidence in a hyperepidemic region of KwaZulu-Natal, South Africa, where adult HIV incidence has recently declined. Median age of HIV seroconversion increased by 5.5 y in men and 3.0 y in women, and the age of peak HIV incidence increased by 5.0 y in men and 2.0 y in women. Incidence declined disproportionately among young men (64% in men 15 to 19, 68% in men 20 to 24, and 46% in men 25 to 29) and young women (44% in women 15 to 19, 24% in women 20 to 24) comparing periods pre- versus post-universal test and treat. Incidence was stable (<20% change) in women aged 30 to 39 and men aged 30 to 34. Age shifts in incidence occurred after 2012 and were observed earlier in men than in women. These results provide direct epidemiological evidence of the changing demographics of HIV risk in sub-Saharan Africa in the era of large-scale treatment and prevention. More attention is needed to address lagging incidence decline among older individuals.

Mixed-method estimation of population-level HIV viral suppression rate in the Western Cape, South Africa

INTRODUCTION

There are few population-wide data on viral suppression (VS) that can be used to monitor programmatic targets in sub-Saharan Africa. We describe how routinely collected viral load (VL) data from antiretroviral therapy (ART) programmes can be extrapolated to estimate population VS and validate this using a combination of empiric and model-based estimates.

METHODS

VL test results from were matched using a record linkage algorithm to obtain linked results for individuals. Test-level and individual-level VS rates were based on test VL values <1000 cps/mL, and individual VL <1000 cps/mL in a calendar year, respectively. We calculated population VS among people living with HIV (PLWH) in the province by combining census-derived midyear population estimates, HIV prevalence estimates and individual level VS estimates from routine VL data.

RESULTS

Approximately 1.9 million VL test results between 2008 and 2018 were analysed. Among individuals in care, VS increased from 85.5% in 2008 to 90% in 2018. Population VS among all PLWH in the province increased from 12.2% in 2008 to 51.0% in 2017. The estimates derived from this method are comparable to those from other published studies. Sensitivity analyses showed that the results are robust to variations in linkage method, but sensitive to the extreme combinations of assumed VL testing coverage and population HIV prevalence.

CONCLUSION

While validation of this method in other settings is required, this approach provides a simple, robust method for estimating population VS using routine data from ART services that can be employed by national programmes in high-burden settings.

Unsuppressed Viral Load Level in Public Health Facilities: Nonvirological Predictors among Adult Antiretroviral Therapy Users in Southwestern Ethiopia

BACKGROUND

Unsuppressed viral load in patients on antiretroviral (ARV) therapy occurs when treatment fails to suppress a patient's viral load, and is associated with decreased survival and increased HIV transmission. Identifying the level of unsuppressed viral load with its associated factors has benefits in controlling transmission and reducing burden. Therefore, this study aimed to assess unsuppressed viral load (>1,000 copies/mL) and associated factors among HIV patients taking first-line antiretroviral treatment at public health facilities in Jimma, Ethiopia.

METHODS

A facility-based cross-sectional study was conducted on 669 patients on first-line ARV therapy (at least 6 months) in public health facilities in Jimma. Sociodemographic, treatment, clinical, immunological, and viral load data were extracted from medical records, entered into EpiData 3.1, and analyzed with SPSS 20. Multivariate logistic regression analysis was performed to identify factors independently associated with viral nonsuppression, considering a 95% CI with P<0.05 statistically significant.

RESULTS

Among the participants, 258 (38.6%) were aged 25-34 years. Median age was 35 years. Prevalence of unsuppressed viral load was 20.3%. Risk of unsuppressed viral loads was 91% lower among ARV therapy patients who had been taking ARV therapy <2 years (AOR 0.09, 95% CI 0.01-0.83), lower baseline BMI (AOR 4.44, 95% CI 1.56-12.64), lower baseline CD4 (AOR 2.76, 95% CI 1.45-5.29), poor adherence to ARV therapy medication (AOR 3.19, 95% CI 1.29-7.89), and immunological failure (AOR 4.26, 95% CI 2.56-7.09) were the independent predictors of unsuppressed viral load.

CONCLUSION

This study revealed that there is a high level of virological failure among adult HIV patients, and confirms the need to develop close follow-up strategies of targeted interventions for patients in care who are at high risk of unsuppressed viral load.

Potential Impact and Cost-Effectiveness of Condomless-Sex-Concentrated PrEP in KwaZulu-Natal Accounting for Drug Resistance

INTRODUCTION

Oral preexposure prophylaxis (PrEP) in the form of tenofovir-disoproxil-fumarate/emtricitabine is being implemented in selected sites in South Africa. Addressing outstanding questions on PrEP cost-effectiveness can inform further implementation.

METHODS

We calibrated an individual-based model to KwaZulu-Natal to predict the impact and cost-effectiveness of PrEP, with use concentrated in periods of condomless sex, accounting for effects on drug resistance. We consider (1) PrEP availability for adolescent girls and young women aged 15-24 years and female sex workers, and (2) availability for everyone aged 15-64 years. Our primary analysis represents a level of PrEP use hypothesized to be attainable by future PrEP programs.

RESULTS

In the context of PrEP use in adults aged 15-64 years, there was a predicted 33% reduction in incidence and 36% reduction in women aged 15-24 years. PrEP was cost-effective, including in a range of sensitivity analyses, although with substantially reduced (cost) effectiveness under a policy of ART initiation with efavirenz- rather than dolutegravir-based regimens due to PrEP undermining ART effectiveness by increasing HIV drug resistance.

CONCLUSIONS

PrEP use concentrated during time periods of condomless sex has the potential to substantively impact HIV incidence and be cost-effective.

What gaps remain in the HIV cascade of care? Results of a population-based survey in Nsanje District, Malawi

INTRODUCTION

The Malawi Ministry of Health (MoH) has been in collaboration with Médecins sans Frontières (MSF) to increase access to quality HIV care through decentralization of antiretroviral therapy (ART) diagnosis and treatment from hospital to clinics in Nsanje District since 2011. A population-based household survey was implemented to provide information on HIV prevalence and cascade of care to inform and prioritize community-based HIV interventions in the district.

METHODS

A cross-sectional survey was conducted between September 2016 and January 2017. Using two-stage cluster sampling, eligible adult individuals aged ≥15 years living in the selected households were asked to participate. Participants were interviewed and tested for HIV at home. Those tested HIV-positive had their HIV-RNA viral load (VL) measured, regardless of their ART status. All participants tested HIV-positive at the time of the survey were advised to report their HIV test result to the health facility of their choice that MSF was supported in the district. HIV-RNA VL results were made available in this health facility.

RESULTS

Among 5,315 eligible individuals, 91.1% were included in the survey and accepted an HIV test. The overall prevalence was 12.1% (95% Confidence Interval (CI): 11.2-13.0) and was higher in women than in men: 14.0% versus 9.5%, P<0.001. Overall HIV-positive status awareness was 80.0% (95%CI: 76.4-83.1) and was associated with sex (P<0.05). Linkage to care was 78.0% (95%CI: 74.3-81.2) and participants in care 76.2% (95%CI: 72.4-79.5). ART coverage among participants aware of their HIV-positive status was 95.3% (95%CI: 92.9-96.9) and was not associated with sex (P = 0.55). Viral load suppression among participants on ART was 89.9% (95%CI: 86.6-92.4) and was not statistically different by sex (p = 0.40).

CONCLUSIONS

Despite encouraging results in HIV testing coverage, cascade of care, and UNAIDS targets in Nsanje District, some gap remains in the first 90, specifically among men and young adults. Enhanced community engagement and new strategies of testing, such as index testing, could be implemented to identify those who are still undiagnosed, particularly men and young adults.

Prevalence and Predictors of Persistent Human Immunodeficiency Virus Viremia and Viral Rebound After Universal Test and Treat: A Population-Based Study

BACKGROUND

There are limited data on individual human immunodeficiency virus (HIV) viral load (VL) trajectories at the population-level after the introduction of universal test and treat (UTT) in sub-Saharan Africa.

METHODS

Human immunodeficiency virus VLs were assessed among HIV-positive participants through 3 population-based surveys in 4 Ugandan fishing communities surveyed between November 2011 and August 2017. The unit of analysis was a visit-pair (2 consecutive person-visits), which were categorized as exhibiting durable VL suppression, new/renewed VL suppression, viral rebound, or persistent viremia. Adjusted relative risks (adjRRs) and 95% confidence intervals (CIs) of persistent viremia were estimated using multivariate Poisson regression.

RESULTS

There were 1346 HIV-positive participants (n = 1883 visit-pairs). The population-level prevalence of durable VL suppression increased from 29.7% to 67.9% during UTT rollout, viral rebound declined from 4.4% to 2.7%, and persistent viremia declined from 20.8% to 13.3%. Younger age (15-29 vs 40-49 years; adjRR = 1.80; 95% CI = 1.19-2.71), male sex (adjRR = 2.09, 95% CI = 1.47-2.95), never being married (vs currently married; adjRR = 1.88, 95% CI = 1.34-2.62), and recent migration to the community (vs long-term resident; adjRR = 1.91, 95% CI = 1.34-2.73) were factors associated with persistent viremia.

CONCLUSIONS

Despite increases in durable VL suppression during roll out of UTT in hyperendemic communities, a substantial fraction of the population, whose risk profile tended to be younger, male, and mobile, remained persistently viremic.

Built Environment and HIV Linkage to Care in Rural South Africa

Background

We assessed built environment (residential density, landuse mix and aesthetics) and HIV linkage to care (LTC) among 1,681 (18–49 years-old) residents of 15 Mpumalanga villages, South Africa.

Methods

Multilevel models (linear-binomial) were used for the association between built environment, measured using NEWS for Africa, and LTC from a clinical database of 9 facilities (2015–2018). Additionally, we assessed effect-measure modification by universal test-and-treat policy (UTT).

Results

We observed, a significant association in the adjusted 3-month probability of LTC for residential density (risk difference (RD)%: 5.6, 95%CI: 1.2–10.1), however, no association for land-use mix (RD%: 2.4, 95%CI: −0.4, 5.2) and aesthetics (RD%: −1.2, 95%CI: −4.5–2.2). Among those diagnosed after UTT, residents of high land-use villages were more likely to link-to-care than those of low land-use villages at 12 months (RD%: 4.6, 95%CI: 1.1–8.1, p < 0.04), however, not at 3 months (RD%: 3.0, 95%CI: −2.1–8.0, p > 0.10).

Conclusion

Findings suggest, better built environment conditions (adequate infrastructure, proximity to services etc.) help facilitate LTC. Moreover, UTT appears to have a protective effect on LTC.

High Coverage of Antiretroviral Treatment With Annual Home-Based HIV Testing, Follow-up Linkage Services, and Implementation of Test and Start: Findings From the Chókwè Health Demographic Surveillance System, Mozambique, 2014-2019

BACKGROUND

Early antiretroviral therapy (ART) is necessary for HIV epidemic control and depends on early diagnosis and successful linkage to care. Since 2014, annual household-based HIV testing and counseling and linkage services have been provided through the Chókwè Health and Demographic Surveillance System for residents testing HIV positive in this high HIV-burden district.

METHODS

District-wide Test and Start [T&S, ART for all people living with HIV (PLHIV)] began in August 2016, supported by systematic interventions to improve linkage to care and treatment. Annual rounds (R) of random household surveys were conducted to assess trends in population prevalence of ART use and viral load suppression (<1000 viral RNA copies/mL).

RESULTS

Between R1 (April 2014-April 2015) and R5 (April 2018-Mar 2019), 46,090 (67.2%) of 68,620 residents aged 15-59 years were tested for HIV at home at least once, and 3711 were newly diagnosed with HIV and provided linkage services. Population prevalence of current ART use among PLHIV increased from 65.0% to 87.5% between R1 and R5. ART population prevalence was lowest among men aged 25-34 years (67.8%) and women aged 15-24 (78.0%), and highest among women aged 35-44 years (93.6%) and 45-59 years (93.7%) in R5. Viral load suppression prevalence increased among all PLHIV aged 15-59 years from 52.0% in R1 to 78.3% in R5.

DISCUSSION

Between 2014 and 2019, Chókwè Health and Demographic Surveillance System residents surpassed the UNAIDS targets of ≥81% of PLHIV on ART and ≥73% virally suppressed. This achievement supports the combination of efforts from household-based HIV testing and counseling, support for linkage to care and treatment, and continued investments in T&S implementation.

How Does the Covıd-19 Pandemıc Affect the Target 90-90-90?

In 2014, The Joint United Nations Program on HIV and AIDS (UNAIDS) has set an ambitious target code-named 90-90-90, which aims to ensure that 90% of all people living with HIV will know their state, 90% of all people diagnosed will receive sustained antiretroviral therapy, and 90% of all people receiving ART will have viral suppression by 2020. Since 2014, many tests and treatment programs have been developed to achieve the above goals worldwide. In 2019, it was reported that many developed countries can reach the target with the right strategies, as well as regions that are still far from the targets. It has been reported that the fourth 90 should be one of the targets related to HIV infection in recent years. This view, beyond virological suppression, was towards developing programs that would enable people living with HIV to live not only longer but also healthy. The socio-cultural and economic obstacles to reach the targets may vary according to geographical regions, but it is clear that COVID-19 disease, which has taken the whole world under the influence since 2019, is a major obstacle to the 90-90-90 targets worldwide. Difficulties in the diagnosis and access to ART and treatment nonadherence which may be encountered more frequently due to many factors may threaten both the health of people living with HIV and public health. The COVID-19 pandemic has disrupted many programs developed in the fight against the HIV epidemic. Considering COVID-19 disease and future epidemics that may create a chaotic environment, analyzing the difficulties experienced in the pandemic retrospectively, and determining new strategies that will bring appropriate solutions to the problems will play an important role in the proper management of future issues.

Access to HIV services and viral load suppression among children during the 90-90-90 strategy implementation in South Africa: A time series analysis

Background

During the era of the Millennium Development Goals (MDG), children were shown to have less access to human immunodeficiency virus (HIV) services than their adult counterparts; hence the call to prioritise children in the implementation of the Sustainable Development Goals (SDGs). However, South African (SA) national data in 2019 indicated that almost 3 years into the implementation of the 90-90-90 strategy, only 59% of children living with HIV had been tested for HIV compared to 90% of adults.

Objectives

To evaluate the access of children to HIV services and record the viral load (VL) suppression rates during the implementation of the 90-90-90 strategy in the City of Johannesburg (COJ), South Africa.

Methods

This study applied a quasi-experimental interrupted time-series (ITS) design using the monthly District Health Information System (DHIS) and National Health Laboratory Services (NHLS) databases spanning the period from 2015 to 2020, that is, before and after the implementation and roll-out of the 90-90-90 strategy. Data were extracted from these databases into MS Excel 2010 spreadsheets and analysed with Stata 15 software from Stata Corp using a two-tailed t-test at a 5% level of significance.

Results

Overall, a significant increase was observed in the number of individuals tested for HIV, n = 757, p = 0.0086, and retained in care n = 2523, p = 0.001 over the whole period of analysis beginning in April 2015. Adult HIV testing, antiretroviral treatment (ART) initiation and retention in care had been decreasing in absolute numbers over a 10-month period before the intervention. An increase in these three data elements was observed following the implementation of the 90-90-90 program. On the other hand, children aged 0–15 years had demonstrated a significant increase in absolute numbers tested for HIV, n = 171, p = 0.001, but an insignificant increase in number of ART initiations, n = 14.33, p = 0.252, before implementation but a decrease after this. The overall VL suppression rates for children were lower than those of adults.

Conclusion

Although the COJ has recorded progress in adult HIV testing, ART initiation and retention, children living with HIV aged 0–15 years continue to experience less access to HIV services and lower VL suppression than youths and adults of ≥ 15 years. Therefore, to ensure that the 90-90-90 targets are achieved across different age groups, children must be prioritised so that they can equally access these services with adults.

Depression symptoms, HIV testing, linkage to ART, and viral suppression among women in a high HIV burden district in KwaZulu-Natal, South Africa: A cross-sectional household study

Achieving the UNAIDS 90-90-90 targets by 2020 is contingent on identifying and addressing mental health challenges that may affect HIV testing and treatment-related behaviors. This study is based on survey data from KwaZulu-Natal, South Africa (2014–2015). HIV positive women who reported higher depression scores had a lower odds of having tested previously for HIV (15–25 years: AOR = 0.90, 95% CI [0.83, 0.98]; 26–49 years: AOR = 0.90, 95% CI [0.84, 0.96]). Because HIV testing behavior represents a gateway to treatment, the findings suggest mental health may be one challenge to attaining the UNAIDS 90-90-90 targets.

The potential impact of urine-LAM diagnostics on tuberculosis incidence and mortality: A modelling analysis

BACKGROUND

Lateral flow urine lipoarabinomannan (LAM) tests could offer important new opportunities for the early detection of tuberculosis (TB). The currently licensed LAM test, Alere Determine TB LAM Ag ('LF-LAM'), performs best in the sickest people living with HIV (PLHIV). However, the technology continues to improve, with newer LAM tests, such as Fujifilm SILVAMP TB LAM ('SILVAMP-LAM') showing improved sensitivity, including amongst HIV-negative patients. It is important to anticipate the epidemiological impact that current and future LAM tests may have on TB incidence and mortality.

METHODS AND FINDINGS

Concentrating on South Africa, we examined the impact that widening LAM test eligibility would have on TB incidence and mortality. We developed a mathematical model of TB transmission to project the impact of LAM tests, distinguishing 'current' tests (with sensitivity consistent with LF-LAM), from hypothetical 'future' tests (having sensitivity consistent with SILVAMP-LAM). We modelled the impact of both tests, assuming full adoption of the 2019 WHO guidelines for the use of these tests amongst those receiving HIV care. We also simulated the hypothetical deployment of future LAM tests for all people presenting to care with TB symptoms, not restricted to PLHIV. Our model projects that 2,700,000 (95% credible interval [CrI] 2,000,000-3,600,000) and 420,000 (95% CrI 350,000-520,000) cumulative TB incident cases and deaths, respectively, would occur between 2020 and 2035 if the status quo is maintained. Relative to this comparator, current and future LAM tests would respectively avert 54 (95% CrI 33-86) and 90 (95% CrI 55-145) TB deaths amongst inpatients between 2020 and 2035, i.e., reductions of 5% (95% CrI 4%-6%) and 9% (95% CrI 7%-11%) in inpatient TB mortality. This impact in absolute deaths averted doubles if testing is expanded to include outpatients, yet remains <1% of country-level TB deaths. Similar patterns apply to incidence results. However, deploying a future LAM test for all people presenting to care with TB symptoms would avert 470,000 (95% CrI 220,000-870,000) incident TB cases (18% reduction, 95% CrI 9%-29%) and 120,000 (95% CrI 69,000-210,000) deaths (30% reduction, 95% CrI 18%-44%) between 2020 and 2035. Notably, this increase in impact arises largely from diagnosis of TB amongst those with HIV who are not yet in HIV care, and who would thus be ineligible for a LAM test under current guidelines. Qualitatively similar results apply under an alternative comparator assuming expanded use of GeneXpert MTB/RIF ('Xpert') for TB diagnosis. Sensitivity analysis demonstrates qualitatively similar results in a setting like Kenya, which also has a generalised HIV epidemic, but a lower burden of HIV/TB coinfection. Amongst limitations of this analysis, we do not address the cost or cost-effectiveness of future tests. Our model neglects drug resistance and focuses on the country-level epidemic, thus ignoring subnational variations in HIV and TB burden.

CONCLUSIONS

These results suggest that LAM tests could have an important effect in averting TB deaths amongst PLHIV with advanced disease. However, achieving population-level impact on the TB epidemic, even in high-HIV-burden settings, will require future LAM tests to have sufficient performance to be deployed more broadly than in HIV care.

Global inequalities in HIV infection

HIV infection continues to be one of the world's greatest pandemics, affecting nearly every country on the globe. By September 2018, it is estimated that 38 million people were living with HIV, 30 million people are aware of their status, and 23 million people are taking anti-retroviral therapy (8 million in 2010). Thus, currently 8 million people living with HIV are not aware that they are HIV-positive and 15 million persons are not being treated. There are nearly 15 million orphans (aged 0-17). There is widespread inequality both in the prevalence of HIV infection and in the access to therapy. However, although the number of people living with HIV continues to increase, the number of new infections shows a steady decrease over the last 9 years and in 2018 was 1.7 million. Deaths from AIDS in 2018 also decreased to 750,000 from 1.2 million in 2010. The world prevalence of HIV is about 0.23% but is over 0.3% in South-East Asia, Latin America, North America and Eastern Europe and with particularly high prevalence in the Caribbean (1.1%) and sub-Saharan Africa (5.5%). It is approximately 0.5% in Indonesia. There were approximately 5,000 new HIV infections (adults and children) a day during 2018. About 61% were in sub-Saharan Africa, nearly 50% were in females and 500 were in children. HIV therapy seems to have had a global impact, with AIDS-related deaths decreasing by 33% since 2010, and new infections decreasing by 16%. Nevertheless, the majority of the world's HIV is in low and middle resource countries and social determinants are strongly related. Many people living with HIV or at risk for HIV still do not have access to prevention, care and treatment, and there is still no cure.

The effect of HIV status on post-stroke outcomes in personal activities of daily living

Introduction

This study explored the impact of HIV on the functional recovery of personal activities of daily living of stroke survivors. This assisted in identifying possible implications for the rehabilitation of stroke survivors who are also HIV-positive.

Method

A quantitative, descriptive, longitudinal comparative research design was used to determine the change in personal activities of daily living scores of HIV-negative and HIV-positive stroke survivors from admission to 1 month after discharge. Data were collected at a rehabilitation unit using the South African Database Functional Measure.

Results

There was no difference in the rate and nature of functional recovery of personal activities of daily living between the two groups between admission and discharge. A difference was noticed during the period from admission to 1 month after discharge, during which the HIV-negative group continued to show improvement, while the HIV-positive group showed little improvement or a decline in personal activities of daily living scores.

Conclusions

While the rate and nature of functional recovery related to personal activities of daily living for HIV-positive and HIV-negative stroke survivors is similar during inpatient care, discharge planning for the HIV-positive group needs to consider the decline in personal activities of daily living functioning post discharge. Regular follow-ups and the inclusion of the stroke survivors in an outpatient treatment programme is recommended.

Successes and gaps in the HIV cascade of care of a high HIV prevalence setting in Zimbabwe: a population-based survey

INTRODUCTION

Gutu, a rural district in Zimbabwe, has been implementing comprehensive HIV care with the support of Médecins Sans Frontières (MSF) since 2011, decentralizing testing and treatment services to all rural healthcare facilities. We evaluated HIV prevalence, incidence and the cascade of care, in Gutu District five years after MSF began its activities.

METHODS

A cross-sectional study was implemented between September and December 2016. Using multistage cluster sampling, individuals aged ≥15 years living in the selected households were eligible. Individuals who agreed to participate were interviewed and tested for HIV at home. All participants who tested HIV-positive had their HIV-RNA viral load (VL) measured, regardless of their antiretroviral therapy (ART) status, and those not on ART with HIV-RNA VL ≥ 1000 copies/mL had Limiting-Antigen-Avidity EIA Assay for cross-sectional estimation of population-level HIV incidence.

RESULTS

Among 5439 eligible adults ≥15 years old, 89.0% of adults were included in the study and accepted an HIV test. The overall prevalence was 13.6% (95%: Confidence Interval (CI): 12.6 to 14.5). Overall HIV-positive status awareness was 87.4% (95% CI: 84.7 to 89.8), linkage to care 85.5% (95% CI: 82.5 to 88.0) and participants in care 83.8% (95% CI: 80.7 to 86.4). ART coverage among HIV-positive participants was 83.0% (95% CI: 80.0 to 85.7). Overall, 71.6% (95% CI 68.0 to 75.0) of HIV-infected participants had a HIV-RNA VL < 1000 copies/mL. Women achieved higher outcomes than men in the five stages of the cascade of care. Viral Load Suppression (VLS) among participants on ART was 83.2% (95% CI: 79.7 to 86.2) and was not statistically different between women and men (p = 0.98). The overall HIV incidence was estimated at 0.35% (95% CI 0.00 to 0.70) equivalent to 35 new cases/10,000 person-years.

CONCLUSIONS

Our study provides population-level evidence that achievement of HIV cascade of care coverage overall and among women is feasible in a context with broad access to services and implementation of a decentralized model of care. However, the VLS was relatively low even among participants on ART. Quality care remains the most critical gap in the cascade of care to further reduce mortality and HIV transmission.

ART use and associated factors among HIV positive caregivers of orphans and vulnerable children in Tanzania

Background

Utilization of antiretroviral therapy (ART) is crucial for better health outcomes among people living with the human immunodeficiency virus (PLHIV). Nearly 30% of the 1.6 million PLHIV in Tanzania are not on treatment. Since HIV positive status is the only eligibility criterion for ART use, it is critical to understand the obstacles to ART access and uptake to reach universal coverage of ART among PLHIV. For the caregivers of orphans and vulnerable children (OVC) LHIV and not on ART, attempts to identify them and ensure that they initiate and continue using ART is critical for their wellbeing and their ability to care for their children.

Methods

Data are from the community-based, United States Agency for International Development (USAID)-funded Kizazi Kipya project that aims at scaling up the uptake of HIV/AIDS and other health and social services by orphans and vulnerable children (OVC) and their caregivers. HIV positive caregivers of OVC who were enrolled in the USAID Kizazi Kipya project between January 2017 and June 2018 were included in this cross-sectional study. The caregivers were drawn from 11 regions: Arusha, Iringa, Katavi, Kigoma, Mara, Mbeya, Morogoro, Ruvuma, Simiyu, Singida, and Tanga. The outcome variable was ART status (either using or not), which was enquired of each OVC caregiver LHIV at enrollment. Data analysis involved multivariable analysis using random-effects logistic regression to identify correlates of ART use.

Results

In total, 74,999 caregivers living with HIV with mean age of 44.4 years were analyzed. Of these, 96.4% were currently on ART at enrollment. In the multivariable analysis, ART use was 30% lower in urban than in rural areas (adjusted odds ratio (OR) = 0.70, 95% confidence interval (CI) 0.61–0.81). Food security improved the odds of being on ART (OR = 1.29, 95% CI 1.15–1.45). Disabled caregivers were 42% less likely than non-disabled ones to be on ART (OR = 0.58, 95% CI 0.45–0.76). Male caregivers with health insurance were 43% more likely than uninsured male caregivers to be on ART (OR = 1.43, 95% CI 1.11–1.83). Caregivers aged 40–49 years had 18% higher likelihood of being on ART than the youngest ones. Primary education level was associated with 26% increased odds of being on ART than no education (OR = 1.26, 95% CI 1.13–1.41).

Conclusions

Although nearly all the caregivers LHIV in the current study were on ART (96.4%), more efforts are needed to achieve universal coverage. The unreached segments of the population LHIV, even if small, may lead to worse health outcomes, and also spur further spread of the HIV epidemic due to unachieved viral suppression. Targeting caregivers in urban areas, food insecure households, who are uninsured, and those with mental or physical disability can improve ART coverage among caregivers LHIV.

Improving inpatient provider-initiated HIV testing and counseling in Sierra Leone

Background/setting

Only 47% of HIV-positive Sierra Leoneans knew their status in 2017, making expanded HIV testing a priority. National guidelines endorse provider-initiated HIV testing and counselling (PITC) to increase testing coverage, but PITC is rarely provided in Sierra Leone. In response, a Quality Improvement Collaborative (QIC) was implemented to improve PITC coverage amongst adult inpatients.

Methods

Ten hospitals received the intervention between October 2017 and August 2018; there were no control facilites. Each hospital aimed to improve PITC coverage to ≥ 95% of eligible patients. Staff received training on PITC and QIC methods and a package of PITC best practices and tools. They then worked to identify additional contextually-appropriate interventions, conducted rapid tests of change, and tracked performance using shared indicators and time-series data. Supportive supervision bolstered QI skills, and quarterly meetings enabled diffusion of innovations while spurring friendly competition.

Results

Baseline PITC coverage was 4%. The hospital teams tested diverse interventions using QI methods, including staff training; data review meetings; enhanced workflow processes and supervision; and patient education and sensitization activities Nine hospitals reached and sustained the 95% target, and all saw rapid and durable improvement, which was sustained for a median of six months. Of the 5,238 patients tested for HIV, 311 (6%) were found to be HIV-positive and were referred for treatment. HIV rapid test kit stockouts occurred during the project period, limiting PITC services in some cases.

Conclusions

The intervention led to swift and sustained improvement in inpatient PITC coverage and to the diagnosis of hundreds of people living with HIV. Sierra Leone’s Ministry of Health and Sanitation plans to take the initiative to national scale, with close attention to the issue of test kit stockouts.

HIV epidemic and cascade of care in 12 east African rural fishing communities: results from a population-based survey in Uganda

Background

In East Africa, fishing communities are considered most-at-risk populations for the acquisition of HIV. We estimated HIV prevalence and assessed progress towards the UNAIDS 90–90-90 targets along the HIV treatment cascade in 12 fishing communities surrounding Lakes Edward and George, Uganda.

Methods

We conducted a cross-sectional household-based survey between September and November 2016. All adults between 15 and 69 years old were eligible to participate. Children below 15 years old were eligible for HIV testing if either parent was HIV-positive. Viral load testing was done for all HIV-infected individuals. Logistic regression models adjusted for sociodemographic-behavioral variables were used to assess the association between occupation and HIV positivity.

Results

Overall, 1738 adults (959 women, 779 men) and 148 children were included. Adult inclusion rate was 96.0%. Of the men, 58% reported to be fishermen. The HIV-prevalence among adults was 17.5% (95%CI: 15.8–19.4) and 6.1% (95%CI: 3.1–11.4) among HIV-exposed children. HIV prevalence was higher among women than among men (20.9% vs. 13.5%, p < 0.001). Among men, fishermen had a higher HIV prevalence (18.7%; 95%CI: 15.1–22.3) and a higher risk of being HIV-positive (aOR: 4.2; 95%CI: 2.0–9.1) than men of other occupations (p < 0.001). Progress towards the UNAIDS 90–90-90 targets was as follows: 86.5% (95%CI: 82.3–90.1%) of the HIV-positive participants were diagnosed, 98.7% (95%CI: 96.1–99.6%) of those aware were on antiretroviral therapy (ART), and 87.3% (95%CI: 82.3–91.0%) of those on ART were virally suppressed. Overall, 73% of all HIV-positive individuals were virally suppressed. Viral suppression was lower among individuals 15–24 years (45.5%) than among those 25–44 years (74.0%) and 45–69 years (85.0%), p < 0.001. Fishermen did not to have significant differences in the HIV cascade of care compared to men with other occupations.

Conclusions

HIV prevalence was high in these fishing communities, particularly among women and fishermen. Important progress has been made along the HIV treatment cascade, and the UNAIDS goal for viral suppression in population was achieved. However, gaps remain and HIV care strategies focusing on young people are urgently needed. HIV preventive interventions should target particularly women, young people and fishermen though HIV preventive and care services should remain available to the whole fishing communities.

A community-based HIV counselling and testing programme found a decreasing proportion of new HIV testers in South Africa

This article assesses the history of HIV testing among community-based HIV counselling and testing (CBCT) clients between 2014 and 2018 in 13 South African districts. Consenting clients were tested for HIV and interviewed to categorise as first-time testers or repeat testers. Of the 1 800 753 clients tested for HIV, 15.7% (95% CI [15.6-15.7]) were first-time testers. The rate of identifying first-time testers decreased by 10.7% in four years from 18.4% in year one to 7.7% in year four. A substantial proportion (5.5% [5.4-5.6]) of HIV-positive people not yet on antiretroviral treatment sought HIV re-test, of whom nearly half (48.4% [47.1-49.6]) did not disclose their HIV-positive status during pre-counselling and were re-tested. A decreasing proportion of first-time testers may signal positive progress towards universal HIV testing. This downward trend should be sustained to control the HIV epidemic.

High levels of viral load monitoring and viral suppression under Treat All in Rwanda - a cross-sectional study

INTRODUCTION

Aiming to reach UNAIDS 90-90-90 targets, nearly all sub-Saharan African countries have expanded antiretroviral therapy (ART) to all people living with HIV (PLWH) (Treat All). Few published data exist on viral load testing and viral suppression under Treat All in this region. We assessed proportions of patients with available viral load test results and who were virally suppressed, as well as factors associated with viral suppression, among PLWH in 10 Rwandan health centres after Treat All implementation.

METHODS

Cross-sectional study during 2018 of adults (≥15 years) engaged in HIV care at 10 Rwandan health centres. Outcomes were being on ART (available ART initiation date in the study database, with no ART discontinuation prior to 1 January 2018), retained on ART (≥2 post-ART health centre visits ≥90 days apart during 2018), available viral load test results (viral load measured in 2018 and available in study database) and virally suppressed (most recent 2018 viral load <200 copies/mL). We used modified Poisson regression models accounting for clustering by health centre to determine factors associated with being virally suppressed.

RESULTS

Of 12,238 patients, 7050 (58%) were female and 1028 (8%) were aged 15 to 24 years. Nearly all patients (11,933; 97%) were on ART, of whom 11,198 (94%) were retained on ART. Among patients retained on ART, 10,200 (91%) had available viral load results; of these 9331 (91%) were virally suppressed. Viral suppression was less likely among patients aged 15 to 24 compared to >49 years (adjusted prevalence ratio (aPR): 0.83, 95% CI 0.76 to 0.90 and those with pre-ART CD4 counts of <200 compared to ≥500 cells/mm3 (aPR: 0.92, 95% CI 0.90 to 0.93). There was no statistically significant difference in viral suppression among patients who entered after Treat All implementation compared to those who enrolled before 2010 (aPR 0.98, 95% CI 0.94 to 1.03).

CONCLUSIONS

In this large cohort of Rwandan PLWH receiving HIV care after Treat All implementation, patients in study health centres have surpassed the third UNAIDS 90-90-90 target. To ensure all PLWH fully benefit from ART, additional efforts should focus on improving ART adherence among younger persons.

Limitations of the UNAIDS 90-90-90 metrics: a simulation-based comparison of cross-sectional and longitudinal metrics for the HIV care continuum

The Joint United Nations Programme on HIV/AIDS (UNAIDS) 90–90–90 and other cross-sectional metrics can lead to potentially counterintuitive conclusions when used to evaluate health systems’ performance. This study demonstrates how time and population dynamics impact UNAIDS 90–90–90 metrics in comparison with a longitudinal analogue.

An implementation study of oral and blood-based HIV self-testing and linkage to care among men in rural and peri-urban KwaZulu-Natal, South Africa

INTRODUCTION

In South Africa, HIV-infected men are less likely than women to test and know their status (the first UNAIDS "90-90-90" target), and men have worse outcomes across the HIV care cascade. HIV self-testing (HIVST) may address this testing disparity but questions remain over the most effective distribution strategy and linkage following a positive test result. We implemented a men-focused HIVST distribution programme to evaluate components contributing to participation and retention.

METHODS

We conducted an implementation study of multi-venue HIVST kit distribution in rural and peri-urban KwaZulu-Natal (KZN), South Africa. We distributed HIVST kits at community points, workplaces and social venues for on site or take-home use. Clients could choose blood-based or oral-fluid-based HIVST kits and elect to watch an in-person or video demonstration. We provided a USD2 incentive to facilitate reporting test results by phone or SMS. Persons with reactive HIVST results were provided immediate confirmatory tests (if used HIVST on site) or were referred for confirmatory testing (if took HIVST off site) and linkage to care for ART initiation. We describe the testing and linkage cascade in this sample and describe predictors of reactive HIVST results and linkage.

RESULTS

Between July and November 2018, we distributed 4496 HIVST kits in two regions of KZN (96% to men, median age 28 (IQR 23 to 35). Most participants (58%) chose blood-based HIVST and 42% chose oral-swab kits. 11% of men were testing for the first time. A total of 3902 (83%) of testers reported their test result to the study team, with 314 (8%) screening positive for HIV. Among 274 men with reactive HIVST results, 68% linked to ART; no significant predictors of linkage were identified. 10% of kit users reported they would prefer a different type (oral vs. blood) of kit for repeat testing than the type they used.

CONCLUSIONS

HIVST is acceptable to men and rapid distribution with optional testing support is feasible in rural and peri-urban settings. HIVST kits successfully reached younger men and identified undetected infections. Both oral and blood-based HIVST were selected. Scaling up HIVST distribution and guidance may increase the number of first-time testers among men and help achieve the first UNAIDS "90" for men in South Africa.

Impact of Male Partner Involvement on Women's Adherence to the Dapivirine Vaginal Ring During a Phase III HIV Prevention Trial

Although vaginal microbicides for HIV prevention are designed to be female-initiated, male partner influence has been identified as one of the most significant factors impacting women's willingness and ability to use them. As a result, research teams have sought to increase male partner involvement by encouraging disclosure of product use to male partners, promoting male partner engagement in the study through attendance at the study clinic, and helping women to garner male partner support for product use. This paper aims to assess the impact of these three elements of male partner involvement on women's adherence to the dapivirine vaginal ring during MTN-020/ASPIRE, a phase III randomized placebo-controlled clinical trial involving 2629 women in Malawi, South Africa, Uganda, and Zimbabwe. During the study, 64-80% of participants reported disclosure of ring use at each quarterly visit, and 13% reported that their partners had attended the study clinic at some point during the study. At study exit, 66% reported that their partner was supportive, 18% unsupportive, and 17% were unsure. After adjusting for age, site and time in study, women were more likely to have low ring adherence if they had an unsupportive male partner (aRR 1.29, 95% CI 1.03-1.62). Neither disclosure nor clinic attendance directly predicted ring adherence, but disclosure increased the probability of having a supportive partner (aRRR 24.17, 95% CI 16.38-35.66) or an unsupportive partner (aRRR 4.10, 95% CI 2.70-6.24), relative to an unknown level of partner support. Women were also more likely to have a supportive partner if their partner had attended the clinic (aRRR 3.77, 95% CI 1.36-10.42). This study suggests that although the vaginal ring is relatively discreet, lack of support from male partners remains a relevant barrier to use. Though both disclosure and clinic attendance may increase partner support, disclosure may also increase partner opposition. Interventions to reduce male partner opposition are needed to maximize the potential impact of the ring and other PrEP products for HIV prevention.

Young South African Women on Antiretroviral Therapy Perceptions of a Psychological Counselling Program to Reduce Heavy Drinking and Depression

Young women in South Africa remain most at risk for HIV infection. Several factors contribute to the high incidence rate in this population, including hazardous drinking and depression. Addressing common mental disorders (CMDs) such as depression and alcohol use disorders is key to effective HIV treatment. We explored the experiences and perceptions of young South African women on antiretroviral therapy (ART) of a lay health worker (LHW)-delivered psychosocial intervention based on motivational interviewing (MI) and problem-solving therapy (PST) to reduce heavy drinking and depression. We conducted 27 in-depth interviews with young women (aged 18-35) recruited from 16 primary care clinics in the Western Cape province of South Africa. Discussion topics included young women's life experiences leading to their enrollment in the program, their perceptions of the counselling sessions and the quality of their interaction with the counsellor. Qualitative data were analyzed using a framework approach. The findings highlighted the impact adverse life experiences and stressful life circumstances have on young women's use of alcohol and symptoms of depression and the effect this has on ART adherence. The findings suggest that women found the intervention components that helped them develop strategies for coping with their past experiences, managing current life stressors, and regulating negative thoughts and emotions most beneficial. Taken together, these findings confirm the acceptability of LHW-delivered MI-PST counselling for this population, but suggest that the relevance of the MI-PST intervention for this highly vulnerable population could be further enhanced by including a focus on psychological trauma.

Bone Mineral Density, Body Composition, and Mineral Homeostasis Over 24 Months in Urban South African Women With HIV Exposed to Antiretroviral Therapy

Human immunodeficiency virus- (HIV-) infection and antiretroviral therapy (ART) exposure are associated with bone loss. African data are limited despite the region's HIV burden. Of 247 ART-naïve, premenopausal, urban, black African women aged 33.9 ± 6.6 years from Soweto, South Africa, measured at baseline, 110 underwent anthropometry, DXA, and blood and urine collections at 12 and 24 months; 39 were HIV-negative (Nref), 28 were people with HIV (PWH) not ART-exposed for the duration of the study (ART-N), and 43 were PWH who were ART-exposed within the first 12 months (ART-Y). At baseline, the ART-Y group had lower BMI and fat mass than the Nref group. Within 12 months of ART initiation, areal bone mineral density (aBMD) had decreased at the lumbar spine and at the whole body less head, despite increased weight, and hip aBMD had not increased in line with the Nref group. There was no evidence of further bone changes between 12 and 24 months. By 24 months, the ART-Y women had gained weight and fat mass, but remained lighter with less fat than the Nref women. ART initiation normalized the low serum albumin of the ART-Y group at baseline, but was associated with elevated bone turnover markers at 12 and 24 months. Vitamin D status and renal phosphate handling were normal. ART-N had similar aBMD and other characteristics to the Nref group throughout, except unlike the Nref group, weight and fat mass did not increase and serum albumin decreased. This study in African women of childbearing age demonstrated that the bone loss that had occurred in these PWH after ART initiation did not continue after 12 months and that bone loss did not occur in ART-unexposed PWH over 2 years. At 24 months, despite gains in weight and fat mass, ART-exposed women remained lighter, with lower aBMD, fat mass, and higher bone turnover than women without HIV. More studies are required to establish if the bone loss and fat gain reverse, stabilize, or continue with further ART exposure, particularly during and after menopause. © 2020 The Authors.
