A decade of PrEP: the evolution of HIV pre-exposure prophylaxis content and sentiments in South African print news media, 2012-2021.

After nearly a decade of HIV pre-exposure prophylaxis (PrEP) rollout in sub-Saharan Africa, there has been limited study of PrEP messaging in news media. We selected twenty South African newspapers with the highest circulation volumes to retrieve articles published in 2012-2021 mentioning PrEP (N = 249). Using inductive content analysis, we developed a structured codebook to characterise PrEP-related content and sentiments, as well as their evolution over time, in the South African press. Many articles espoused favourable attitudes towards PrEP (52%), but a sizeable fraction espoused unfavourable attitudes (11%). Relative to PrEP-favourable articles, PrEP-unfavourable articles were significantly more likely to emphasise the drawbacks/consequences of PrEP use, including adherence/persistence requirements (52% vs. 24%, p = .007), cost (48% vs. 11%, p < .001), and risk compensation (52% vs. 5%, p < .001). Nevertheless, the presence of these drawbacks/consequences in print media largely declined over time. Key populations (e.g. adolescents, female sex workers) were frequently mentioned potential PrEP candidates. Despite message variations over time, prevention effectiveness and adherence/persistence requirements were the most widely cited PrEP benefits and drawbacks, respectively. Study findings demonstrate the dynamic nature of PrEP coverage in the South African press, likely in response to PrEP scale-up and real-world PrEP implementation during the study period.

HIV- and sex work-related stigmas and quality of life of female sex workers living with HIV in South Africa: a cross-sectional study.

BACKGROUND: Environmental quality of life (QoL) assesses individually perceived factors such as physical safety and security, accessibility, quality of healthcare, and physical environment. These factors are particularly relevant in the context of sex work and HIV, where stigma has been identified as an important barrier across several prevention and treatment domains. This study aims to examine the association between different types of HIV- and sex work-related stigmas and environmental QoL among female sex workers (FSW) living with HIV in Durban, South Africa. METHODS: We conducted cross-sectional analyses using baseline data from the Siyaphambili randomized controlled trial. FSW who reported sex work as their primary source of income and had been diagnosed with HIV for ≥ 6 months were enrolled from June 2018-March 2020, in eThekwini, South Africa. We evaluated the association between environmental QoL, dichotomizing the environmental domain score collected by the WHO Quality of Life HIV Brief (WHOQOL-HIV BREF) questionnaire at the median, and stigma using modified robust Poisson regression models. Five stigma subscales were assessed: sex work-related (anticipated, enacted, or internalized stigma) and HIV-related (anticipated or enacted stigma). RESULTS: Among 1373 FSW, the median environmental QoL was 10.5 out of 20 [IQR: 9.0-12.5; range 4.0-19.0], while the median overall QoL was 3 out of 5 [IQR: 2-4; range 1-5]. One-third of FSW (n = 456) fell above the median environmental QoL score, while 67% were above the median overall QoL (n = 917). Reporting anticipated sex work stigma was associated with lower environmental QoL (adjusted prevalence ratio [aPR] 0.74 [95% CI 0.61, 0.90]), as was severe internalized sex work stigma (aPR: 0.64, 95% CI 0.48, 0.86). Reporting enacted HIV stigma versus none was similarly associated with lower environmental QoL (aPR: 0.65, 95% CI 0.49, 0.87). Enacted sex work stigma and anticipated HIV stigma were not statistically associated with environmental QoL. CONCLUSIONS: This study highlights the need to consider the impact of multiple stigmas on FSW's non-HIV related clinical outcomes, including safety and physical well-being. Moreover, these results suggest that addressing underlying structural risks may support the impact of more proximal HIV prevention and treatment interventions.

Implementing Implementation Research: Teaching Implementation Research to HIV Researchers.

PURPOSE OF REVIEW: Given the growth in HIV-related implementation research, there is a need to expand the workforce and rigor through implementation science (IS) training and mentorship. Our objective is to review IS training opportunities for HIV-focused researchers and describe the approach and lessons learned from a recent HIV-related implementation research training initiative. RECENT FINDINGS: IS training opportunities range from degree programs to short- and longer-term professional development institutes and community-focused institutional trainings. Until recently, there have not been extensive dedicated opportunities for implementation research training for HIV-focused investigators. To meet this gap, an inter-Center for AIDS Research IS Fellowship for early-stage investigators was launched in 2019, building on lessons learned from dissemination and implementation training programs. Key components of the HIV-focused IS fellowship include didactic training, mentorship, grant-writing, and development of HIV-IS collaborative networks. Fellows to-date were two-thirds junior faculty and one-third post-doctoral fellows, the majority (69%) with prior public health training. Perceived value of the program was high, with a median rating of 9 [IQR 8-9] on a 10-point scale. Overall, 22/27 (81%) Fellows from the first cohort submitted IS-related grants within 12 months of Fellowship completion, and by 1 year 13 grants had been funded among 10 investigators, 37% overall among Fellows. Mentors identified framing of IS questions as the top-ranked training priority for HIV-investigators. Increasing knowledge of the utility of IS may support more grants focused on optimal implementation of HIV treatment and prevention strategies. Experiences from mentors and trainees engaged in an IS-focused fellowship for HIV investigators demonstrate the demand and value of a dedicated training program and reinforce the importance of mentorship.

Trajectories of fertility intentions among women living with HIV in South Africa.

Fertility intentions are thought to be dynamic among women of reproductive age, yet few studies have assessed fertility intentions over time among women with HIV. We examine temporal patterns of fertility intentions in women with HIV to assess the extent to which fertility intentions - and the corresponding need for safer conception and judicious antiretroviral therapy (ART) regimen selection - vary over time. 850 non-pregnant HIV-positive women aged 18-35 on or being initiated onto ART in Johannesburg, South Africa were enrolled into a prospective cohort study (2009-2010). Fertility intentions were assessed at enrollment and at 30-day intervals via an interviewer-administered questionnaire. We used group-based trajectory modelling to identify longitudinal patterns of fertility intentions over 12 months. We identified four patterns of fertility intentions, which we labelled "consistently low" (representing ∼60% of the population), "low and increasing" (∼23%), "high and increasing" (∼12%), and "high and decreasing" (∼5%). Our findings suggest that a single family-planning assessment at one time point is insufficient to fully identify and meet the reproductive needs of women with HIV. As HIV testing and treatment evolve in South Africa, routine screening for fertility intentions can offer important opportunities to optimize HIV treatment, prevention, and maternal and child health.

Perceptions of Community and Clinic-Based Adherence Clubs for Patients Stable on Antiretroviral Treatment: A Mixed Methods Study.

Adherence clubs for patients stable on antiretroviral treatment (ART) offer decongestion of clinics and task-shifting, improved adherence and retention in care. Findings on patient acceptability by club location (in the clinic vs. the community) are limited. This was a mixed-methods study set within a randomized controlled trial of community versus clinic-based adherence clubs for retention in care at Witkoppen Health and Welfare Centre in Johannesburg, South Africa. Participants were surveyed on preferences for adherence club-based care (e.g. location, convenience). We conducted in-depth interviews (IDIs) with 36 participants, and surveyed 568 participants: 49% in community-based clubs and 51% in clinic-based clubs. Participants in both arms favorably rated adherence clubs. Almost all (95%) in clinic-based clubs would recommend them to a friend, while fewer (88% in community-based club participants would do so (p = 0.004). Participants found clubs promoted social support, and were convenient and time-saving, though concerns around stigma and access to other health care were noted within community-based clubs. Adherence clubs are a highly acceptable form of differentiated care for stable ART patients. These data indicate that clinic-based clubs may be preferred above community-based clubs, potentially for reasons of stigma and access to additional health care services.

Fertility Intentions and Clinical Care Attendance Among Women Living with HIV in South Africa.

Poor HIV care retention impedes optimal treatment outcomes in persons living with HIV. Women trying to become pregnant may be motivated by periconception horizontal and vertical transmission concerns and thus more likely to attend HIV care visits than women not trying to conceive. We estimated the effect of fertility intentions on HIV care attendance over 12 months among non-pregnant, HIV-positive women aged 18-35 years who were on or initiating antiretroviral therapy in Johannesburg, South Africa. The percentage of women attending an HIV care visit decreased from 93.4% in the first quarter to 82.8% in the fourth quarter. Fertility intentions were not strongly associated with care attendance in this cohort of reproductive-aged women; however, attendance declined over time irrespective of childbearing plans. These findings suggest a need for reinforced efforts to support care engagement and risk reduction, including safer conception practices for women wishing to conceive.

Patients' Satisfaction with HIV Care Providers in Public Health Facilities in Lusaka: A Study of Patients who were Lost-to-Follow-Up from HIV Care and Treatment.

Prognosis among those who are HIV infected has improved but long-term retention is challenging. Health systems may benefit from routinely measuring patient satisfaction which is a potential driver of engagement in HIV care, but it is not often measured in Africa, and Zambia in particular. This study aims to internally validate a patient satisfaction tool, assess satisfaction among patients previously lost-to-follow up (LTFU) from HIV care in Lusaka province and to measure association between patient satisfaction with their original clinic and re-engagement in HIV care. A cross-sectional assessment of satisfaction was conducted by tracing sampled patients drawn from public health facilities. Our findings suggest that satisfaction tool, previously validated in USA, exhibits high internal consistency for measuring patient satisfaction in the Zambian health system. Patient satisfaction with healthcare providers is associated with re-engagement in HIV care. Future interventions on patient-centred care are likely to optimize and support retention in care.

The impact of community- versus clinic-based adherence clubs on loss from care and viral suppression for antiretroviral therapy patients: Findings from a pragmatic randomized controlled trial in South Africa.

BACKGROUND: Adherence clubs, where groups of 25-30 patients who are virally suppressed on antiretroviral therapy (ART) meet for counseling and medication pickup, represent an innovative model to retain patients in care and facilitate task-shifting. This intervention replaces traditional clinical care encounters with a 1-hour group session every 2-3 months, and can be organized at a clinic or a community venue. We performed a pragmatic randomized controlled trial to compare loss from club-based care between community- and clinic-based adherence clubs. METHODS AND FINDINGS: Patients on ART with undetectable viral load at Witkoppen Health and Welfare Centre in Johannesburg, South Africa, were randomized 1:1 to a clinic- or community-based adherence club. Clubs were held every other month. All participants received annual viral load monitoring and medical exam at the clinic. Participants were referred back to clinic-based standard care if they missed a club visit and did not pick up ART medications within 5 days, had 2 consecutive late ART medication pickups, developed a disqualifying (excluding) comorbidity, or had viral rebound. From February 12, 2014, to May 31, 2015, we randomized 775 eligible adults into 12 pairs of clubs-376 (49%) into clinic-based clubs and 399 (51%) into community-based clubs. Characteristics were similar by arm: 65% female, median age 38 years, and median CD4 count 506 cells/mm3. Overall, 47% (95% CI 44%-51%) experienced the primary outcome of loss from club-based care. Among community-based club participants, the cumulative proportion lost from club-based care was 52% (95% CI 47%-57%), compared to 43% (95% CI 38%-48%, p = 0.002) among clinic-based club participants. The risk of loss to club-based care was higher among participants assigned to community-based clubs than among those assigned to clinic-based clubs (adjusted hazard ratio 1.38, 95% CI 1.02-1.87, p = 0.032), after accounting for sex, age, nationality, time on ART, baseline CD4 count, and employment status. Among those who were lost from club-based care (n = 367), the most common reason was missing a club visit and the associated ART medication pickup entirely (54%, 95% CI 49%-59%), and was similar by arm (p = 0.086). Development of an excluding comorbidity occurred in 3% overall of those lost from club-based care, and was not different by arm (p = 0.816); no deaths occurred in either arm during club-based care. Viral rebound occurred in 13% of those lost from community club-based care and 21% of those lost from clinic-based care (p = 0.051). In post hoc secondary analysis, among those referred to standard care, 72% (95% CI 68%-77%) reengaged in clinic-based care within 90 days of their club-based care discontinuation date. The main limitations of the trial are the lack of a comparison group receiving routine clinic-based standard care and the potential limited generalizability due to the single-clinic setting. CONCLUSIONS: These findings demonstrate that overall loss from an adherence club intervention was high in this setting and that, importantly, it was worse in community-based adherence clubs compared to those based at the clinic. We urge caution in assuming that the effectiveness of clinic-based interventions will carry over to community settings, without a better understanding of patient-level factors associated with successful retention in care.

Longitudinal engagement trajectories and risk of death among new ART starters in Zambia: A group-based multi-trajectory analysis.

BACKGROUND: Retention in HIV treatment must be improved to advance the HIV response, but research to characterize gaps in retention has focused on estimates from single time points and population-level averages. These approaches do not assess the engagement patterns of individual patients over time and fail to account for both their dynamic nature and the heterogeneity between patients. We apply group-based trajectory analysis-a special application of latent class analysis to longitudinal data-among new antiretroviral therapy (ART) starters in Zambia to identify groups defined by engagement patterns over time and to assess their association with mortality. METHODS AND FINDINGS: We analyzed a cohort of HIV-infected adults who newly started ART between August 1, 2013, and February 1, 2015, across 64 clinics in Zambia. We performed group-based multi-trajectory analysis to identify subgroups with distinct trajectories in medication possession ratio (MPR, a validated adherence metric based on pharmacy refill data) over the past 3 months and loss to follow-up (LTFU, >90 days late for last visit) among patients with at least 180 days of observation time. We used multinomial logistic regression to identify baseline factors associated with belonging to particular trajectory groups. We obtained Kaplan-Meier estimates with bootstrapped confidence intervals of the cumulative incidence of mortality stratified by trajectory group and performed adjusted Poisson regression to estimate adjusted incidence rate ratios (aIRRs) for mortality by trajectory group. Inverse probability weights were applied to all analyses to account for updated outcomes ascertained from tracing a random subset of patients lost to follow-up as of July 31, 2015. Overall, 38,879 patients (63.3% female, median age 35 years [IQR 29-41], median enrollment CD4 count 280 cells/µl [IQR 146-431]) were included in our cohort. Analyses revealed 6 trajectory groups among the new ART starters: (1) 28.5% of patients demonstrated consistently high adherence and retention; (2) 22.2% showed early nonadherence but consistent retention; (3) 21.6% showed gradually decreasing adherence and retention; (4) 8.6% showed early LTFU with later reengagement; (5) 8.7% had early LTFU without reengagement; and (6) 10.4% had late LTFU without reengagement. Identified groups exhibited large differences in survival: after adjustment, the "early LTFU with reengagement" group (aIRR 3.4 [95% CI 1.2-9.7], p = 0.019), the "early LTFU" group (aIRR 6.4 [95% CI 2.5-16.3], p < 0.001), and the "late LTFU" group (aIRR 4.7 [95% CI 2.0-11.3], p = 0.001) had higher rates of mortality as compared to the group with consistently high adherence/retention. Limitations of this study include using data observed after baseline to identify trajectory groups and to classify patients into these groups, excluding patients who died or transferred within the first 180 days, and the uncertain generalizability of the data to current care standards. CONCLUSIONS: Among new ART starters in Zambia, we observed 6 patient subgroups that demonstrated distinctive engagement trajectories over time and that were associated with marked differences in the subsequent risk of mortality. Further efforts to develop tailored intervention strategies for different types of engagement behaviors, monitor early engagement to identify higher-risk patients, and better understand the determinants of these heterogeneous behaviors can help improve care delivery and survival in this population.

Integrating Cervical Cancer Screening Into Safer Conception Services to Improve Women's Health Outcomes: A Pilot Study at a Primary Care Clinic in South Africa.

BACKGROUND: Sub-optimal cervical cancer screening in low- and middle-income countries contributes to preventable cervical cancer deaths, particularly among human immunodeficiency virus (HIV)-positive women. We assessed feasibility and outcomes of integrating cervical cancer screening into safer conception services for HIV-affected women. METHODS: At a safer conception service in Johannesburg, South Africa, HIV-affected women desiring pregnancy received a standard package of care designed to minimize HIV transmission risks while optimizing prepregnancy health. All eligible women were offered Papanicolaou smear, and those with significant pathology were referred for colposcopy before attempting pregnancy. Multivariable analyses identified associations between patient characteristics and abnormal pathology. RESULTS: In total, 454 women were enrolled between June 2015 and April 2017. At enrolment, 91% were HIV-positive, 92% were on antiretroviral therapy (ART) and 82% virally suppressed. Eighty-three percent (376 of 454) of clients were eligible for cervical cancer screening and 85% (321 of 376) of these completed screening. More than half had abnormal cervical pathology (185 of 321) and 20% required colposcopy for possible high-grade or persistently atypical lesions (64 of 321). Compared with HIV-negative women, abnormal pathology was more likely among HIV-positive women, both those on ART <2 years (adjusted prevalence ratio, 2.5; 95% confidence interval, 1.2-5.0) and those on ART 2 years or longer (adjusted prevalence ratio, 2.1; 95% confidence interval, 1.0-4.2). CONCLUSIONS: Integrating cervical cancer screening into safer conception care was feasible with high coverage, including for HIV-positive women. Significant pathology, requiring colposcopy, was common, even among healthy women on ART. Safer conception services present an opportunity for integration of cervical cancer screening to avert preventable cancer-related deaths among HIV-affected women planning pregnancy.

Subfertility among HIV-affected couples in a safer conception cohort in South Africa.

BACKGROUND: Subfertility among couples affected by HIV has an impact on the well-being of couples who desire to have children and may prolong HIV exposure. Subfertility in the antiretroviral therapy era and its determinants have not yet been well characterized. OBJECTIVE: The objective of the study was to investigate the burden and determinants of subfertility among HIV-affected couples seeking safer conception services in South Africa. STUDY DESIGN: Nonpregnant women and male partners in HIV seroconcordant or HIV discordant relationships desiring a child were enrolled in the Sakh'umndeni safer conception cohort at Witkoppen Clinic in Johannesburg between July 2013 and April 2017. Clients were followed up prospectively through pregnancy (if they conceived) or until 6 months of attempted conception, after which they were referred for infertility services. Subfertility was defined as not having conceived within 6 months of attempted conception. Robust Poisson regression was used to assess the association between baseline characteristics and subfertility outcomes; inverse probability weighting was used to account for missing data from women lost to safer conception care before 6 months of attempted conception. RESULTS: Among 334 couples enrolled, 65% experienced subfertility (inverse probability weighting weighted, 95% confidence interval, 0.59-0.73), of which 33% were primary subfertility and 67% secondary subfertility. Compared with HIV-negative women, HIV-positive women not on antiretroviral therapy had a 2-fold increased risk of subfertility (weighted and adjusted risk ratio, 2.00; 95% confidence interval, 1.19-3.34). Infertility risk was attenuated in women on antiretroviral therapy but remained elevated, even after ≥2 years on antiretroviral therapy (weighted and adjusted risk ratio, 1.63; 95% confidence interval, 0.98-2.69). Other factors associated with subfertility were female age (weighted and adjusted risk ratio, 1.03, 95% confidence interval, 1.01-1.05 per year), male HIV-positive status (weighted and adjusted risk ratio, 1.31; 95% confidence interval, 1.02-1.68), male smoking (weighted and adjusted risk ratio, 1.29; 95% confidence interval, 1.05-1.60), and trying to conceive for ≥1 year (weighted and adjusted risk ratio, 1.38; 95% confidence interval, 1.13-1.68). CONCLUSION: Two in 3 HIV-affected couples experienced subfertility. HIV-positive women were at increased risk of subfertility, even when on antiretroviral therapy. Both male and female HIV status were associated with subfertility. Subfertility is an underrecognized reproductive health problem in resource-limited settings and may contribute to prolonged HIV exposure and transmission within couples. Low-cost approaches for screening and treating subfertility in this population are needed.

Integrating safer conception services into primary care: providers' perspectives.

BACKGROUND: In 2012, South Africa adopted the Contraception and Fertility Planning guidelines to incorporate safer conception services into care for HIV-affected couples trying to conceive. These guidelines lacked clear implementation and training recommendations. The objective of this study was to investigate factors influencing integration of safer conception services in a clinical setting. METHODS: Twenty in-depth interviews were conducted between October-November 2017 with providers and staff at Witkoppen Clinic in Johannesburg, where the Sakh'umndeni safer conception demonstration project had enrolled patients from July 2013-July 2017. Semi-structured interview guides engaged providers on their perspectives following the Sakh'umndeni project and possible integration plans to inform the translation of the stand-alone Sakh'umndeni services into a routine service. A grounded theory approach was used to code interviews and an adaptation of the Atun et al. (2010) 'Integration of Targeted Interventions into Health Systems' conceptual framework was applied as an analysis tool. RESULTS: Five themes emerged: (1) The need for safer conception training; (2) The importance of messaging and demand generation; (3) A spectrum of views around the extent of integration of safer conception services; (4) Limitations of family planning services as an integration focal point; and (5) Benefits and challenges of a "couples-based" intervention. In-depth interviews suggested that counselors, as the first point of contact, should inform patients about safer conceptions services, followed by targeted reinforcement of safer conception messaging by all clinicians, and referral to more intensively trained safer conception providers. CONCLUSION: A safer conception counseling guide would facilitate consultations. While many providers felt that the services belonged in family planning, lack of HIV management skills, men and women trying to conceive within family planning may pose barriers.

Siyaphambili protocol: An evaluation of randomized, nurse-led adaptive HIV treatment interventions for cisgender female sex workers living with HIV in Durban, South Africa.

In South Africa, 60% of female sex workers are estimated to be living with human immunodeficiency virus (HIV). Many of these women face structural and individual-level barriers to initiating, accessing, and adhering to antiretroviral therapy (ART). While data are limited, it is estimated that less than 40% of sex workers living with HIV achieve viral suppression, leading to suboptimal clinical outcomes and sustained risks of onward sexual and vertical HIV transmission. Siyaphambili, a NINR/NIH-funded study, focuses on studying optimal implementation strategies for meeting HIV treatment needs among cisgender female sex workers living with HIV who are not virally suppressed. Here, we present the study protocol of this sequential multiple assignment randomized trial. In total, 800 viremic female sex workers will be enrolled into an 18-month adaptive implementation study to 1) compare the effectiveness and durability of a nurse-led decentralized ART treatment program versus an individualized case management approach, in isolation or in combination to achieve viral suppression and 2) estimate incremental cost-effectiveness of interventions and combinations of interventions. The primary outcome is a combined intention-to-treat outcome of retention in ART care and viral suppression at 18 months with secondary implementation outcomes. Siyaphambili aims to inform the implementation of and scale-up of HIV treatment services for female sex workers by determining the minimal package of services needed to achieve viral suppression and by characterizing individuals in need of more intensive HIV treatment approaches.

Prevalence of latent tuberculosis infection and predictive factors in an urban informal settlement in Johannesburg, South Africa: a cross-sectional study.

BACKGROUND: South Africa has one of the highest burdens of latent tuberculosis infection (LTBI) in high-risk populations such as young children, adolescents, household contacts of TB cases, people living with HIV, gold miners and health care workers, but little is known about the burden of LTBI in its general population. METHODS: Using a community-based survey with random sampling, we examined the burden of LTBI in an urban township of Johannesburg and investigated factors associated with LTBI. The outcome of LTBI was based on TST positivity, with a TST considered positive if the induration was ≥5 mm in people living with HIV or ≥10 mm in those with unknown or HIV negative status. We used bivariate and multivariable logistic regression to identify factors associated with LTBI RESULTS: The overall prevalence of LTBI was 34.3 (95 % CI 30.0, 38.8 %), the annual risk of infection among children age 0-14 years was 3.1 % (95 % CI 2.1, 5.2). LTBI was not associated with HIV status. In multivariable logistic regression analysis, LTBI was associated with age (OR = 1.03 for every year increase in age, 95 % CI = 1.01-1.05), male gender (OR = 2.70, 95 % CI = 1.55-4.70), marital status (OR = 2.00, 95 % CI = 1.31-3.54), and higher socio-economic status (OR = 2.11, 95 % CI = 1.04-4.31). CONCLUSIONS: The prevalence of LTBI and the annual risk of infection with M. tuberculosis is high in urban populations, especially in men, but independent of HIV infection status. This study suggests that LTBI may be associated with higher SES, in contrast to the well-established association between TB disease and poverty.

Maternal Highly Active Antiretroviral Therapy and Child HIV-Free Survival in Malawi, 2004-2009.

OBJECTIVES: Highly active antiretroviral therapy (HAART) provision to eligible HIV-infected pregnant and post-partum women is critical for optimizing maternal health. We assessed the impact of maternal HAART on HIV-free survival of breastfed infants in Malawi. METHODS: The post-exposure prophylaxis of infants-Malawi trial (2004-2009) enrolled mothers/infants during labor or immediately post-partum to evaluate 14-week extended infant antiretroviral prophylaxis for preventing HIV transmission through breastfeeding. Mothers meeting national HAART guidelines were referred for therapy. Child HIV-free survival-survival without HIV infection-was compared by maternal HAART status. RESULTS: Overall, 3022 mother-infant pairs contributed 4214 infant/person-years (PY) at-risk for HIV infection or death, with 532 events (incidence 12.6/100 PY, 95 % confidence interval [CI] 11.6-13.7). During follow-up, 349 mothers were HAART initiated; 581 remained HAART naïve with CD4 cell counts <250 cells/mm(3), and 2092 were never HAART-eligible. By 3 months, 11 % of infants with HAART naïve mothers (CD4 < 250) were infected with HIV or died versus 7 % of infants of HAART-initiated mothers and 4 % of infants of HAART-ineligible mothers. Maternal HAART was associated with a 46 % reduction in infant HIV infection or death as compared to infants with HAART naïve mothers (CD4 < 250) (adjusted hazards ratio 0.54, 95 % CI 0.36-0.81). Among HIV-exposed, uninfected infants, breastfeeding, but not HAART, was significantly associated with decreased child mortality. CONCLUSIONS: HIV infection and mortality are high during the first 3 months post-partum in infants of mothers with advanced HIV, and rapid maternal HAART initiation can significantly improve HIV-related infant outcomes.

Fertility-related research needs among women at the margins.

Fertility-related research encompasses fertility intentions, preconception care, research amongst pregnant women, and post-partum outcomes of mothers and children. However, some women remain under-represented within this domain of study. Women frequently missing within fertility-related research include those who are already the most vulnerable to health disparities, including female sex workers, lesbian, gay, bisexual, and transgender women, women living with HIV, and women who use drugs. Yet characterization of the needs of these women is important, given their unique fertility-related concerns, including risks and barriers to care emanating from social stigmas and discrimination. This synthesis provides an overview of fertility-related evidence, highlighting where there are clear research gaps among marginalized women and the potential implications of these data shortfalls. Overall, research among marginalized women to date has addressed pregnancy prevention and in some cases fertility intentions, but the majority of studies have focused on post-conception pregnancy safety and the well-being of the child. However, among female sex workers specifically, data on pregnancy safety and the well-being of the child are largely unavailable. Within each marginalized group, preconception care and effectiveness of conception methods are consistently understudied. Ultimately, the absence of epidemiologic, clinical and programmatic evidence limits the availability and quality of reproductive health services for all women and prevents social action to address these gaps.

Acceptability and Feasibility of a Mobile Phone-Based Case Management Intervention to Retain Mothers and Infants from an Option B+ Program in Postpartum HIV Care.

The objective of this study was to assess the acceptability and feasibility of a cell phone based case manager intervention targeting HIV-infected pregnant women on highly-active antiretroviral therapy (HAART). Pregnant women ≥36 weeks gestation attending antenatal care and receiving HAART through the Option B+ program at a primary care clinic in South Africa were enrolled into a prospective pilot intervention to receive text messages and telephone calls from a case manager through 6 weeks postpartum. Acceptability and feasibility of the intervention were assessed along with infant HIV testing rates and 10-week and 12-month postpartum maternal retention in care. Retention outcomes were compared to women of similar eligibility receiving care prior to the intervention. Fifty women were enrolled into the pilot from May to July 2013. Most (70%) were HAART-naive at time of conception and started HAART during antenatal care. During the intervention, the case manager sent 482 text messages and completed 202 telephone calls, for a median of 10 text messages and 4 calls/woman. Ninety-six percent completed the postpartum interview and 47/48 (98%) endorsed the utility of the intervention. Engagement in 10-week postpartum maternal HIV care was >90% in the pre-intervention (n = 50) and intervention (n = 50) periods; by 12-months retention fell to 72% and was the same across periods. More infants received HIV-testing by 10-weeks in the intervention period as compared to pre-intervention (90.0 vs. 63.3%, p < 0.01). Maternal support through a cell phone based case manager approach was highly acceptable among South African HIV infected women on HAART and feasible, warranting further assessment of effectiveness.

Safer conception needs for HIV prevention among female sex workers in Burkina Faso and Togo.

BACKGROUND: Reproductive health programming for female sex workers (FSW) may include contraceptive services but rarely addresses safer pregnancy planning. METHODS: Adult FSW were enrolled into a cross-sectional study across four sites in Burkina Faso and Togo using respondent-driven sampling. Sociobehavioral questionnaires and HIV counseling and testing were administered. Sample statistics and engagement in HIV treatment were described and compared using Chi-squared statistics. RESULTS: 1,349 reproductive-aged FSW were enrolled from January to July 2013. Overall, 267 FSW (19.8%) were currently trying to conceive. FSW trying to conceive were more likely to test positive for HIV at enrollment as compared to women not trying to become pregnant (24.5% versus 17.7%, P < 0.01); however awareness of HIV status was similar across groups. Among FSW trying to conceive, 79.0% (211/267) had previously received HIV testing, yet only 33.8% (23/68) of HIV-infected FSW reported a previous HIV diagnosis. Overall 25.0% (17/68) of HIV-infected FSW trying to conceive were on antiretroviral therapy. CONCLUSION: FSW frequently desire children. However engagement in the HIV prevention and treatment cascade among FSW trying to conceive is poor potentiating periconception transmission risks to partners and infants. Programs to facilitate earlier HIV diagnosis for FSW and safer conception counseling are needed as components of effective combination HIV prevention services.

Polysubstance Use Profiles and HIV Viremia in a South African Cohort of Female Sex Workers: A Latent Class Analysis.

BACKGROUND: Given intersecting social and structural factors, female sex workers (FSW) exhibit elevated risk of HIV and substance use. However, there is limited study of how distinct substance use typologies influence HIV treatment outcomes among FSW. SETTING: A cross-sectional survey with objective viral load assessments of 1391 FSW enrolled into a treatment optimization-focused trial in Durban, South Africa (2018-2020). METHODS: We used latent class analysis to uncover discrete patterns in past-month self-reported use of the following substances: heavy alcohol use, cannabis, cocaine, crack, ecstasy, methamphetamine, heroin, and Whoonga . We used Wald tests to identify multilevel predictors of latent class membership and multivariable mixture modeling to quantify associations of substance use classes with HIV viremia (≥50 RNA copies/mL). RESULTS: Substance use (87%) and HIV viremia (62%) were highly prevalent. Latent class analysis uncovered 3 polysubstance use profiles: Heavy Alcohol Use Only (∼54%); Cannabis, Heavy Alcohol, & Crack Use (∼28%); and Whoonga & Crack Use (∼18%). Whoonga & Crack Use was associated with social and structural adversities, including homelessness, outdoor/public sex work, HIV stigma, and violence. Relative to Heavy Alcohol Use Only , HIV viremia was significantly higher in the Whoonga & Crack Use class (adjusted odds ratio 1.97, 95% confidence interval: 1.13 to 3.43), but not in the Cannabis, Heavy Alcohol, & Crack Use class (adjusted odds ratio 1.17, 95% confidence interval: 0.74 to 1.86). CONCLUSION: HIV viremia differed significantly across identified polysubstance use profiles among South African FSW. Integrating drug treatment and harm reduction services into HIV treatment programs is key to improving virologic outcomes in marginalized communities.

Trajectories of re-engagement: factors and mechanisms enabling patient return to HIV care in Zambia.

INTRODUCTION: While disengagement from HIV care threatens the health of persons living with HIV (PLWH) and incidence-reduction targets, re-engagement is a critical step towards positive outcomes. Studies that establish a deeper understanding of successful return to clinical care among previously disengaged PLWH and the factors supporting re-engagement are essential to facilitate long-term care continuity. METHODS: We conducted narrative, patient-centred, in-depth interviews between January and June 2019 with 20 PLWH in Lusaka, Zambia, who had disengaged and then re-engaged in HIV care, identified through electronic medical records (EMRs). We applied narrative analysis techniques, and deductive and inductive thematic analysis to identify engagement patterns and enablers of return. RESULTS: We inductively identified five trajectories of care engagement, suggesting patterns in patient characteristics, experienced barriers and return facilitators that may aid intervention targeting including: (1) intermittent engagement;(2) mostly engaged; (3) delayed linkage after testing; (4) needs time to initiate antiretroviral therapy (ART); and (5) re-engagement with ART initiation. Patient-identified periods of disengagement from care did not always align with care gaps indicated in the EMR. Key, interactive re-engagement facilitators experienced by participants, with varied importance across trajectories, included a desire for physical wellness and social support manifested through verbal encouragement, facility outreach or personal facility connections and family instrumental support. The mechanisms through which facilitators led to return were: (1) the promising of living out one's life priorities; (2) feeling valued; (3) fostering interpersonal accountability; (4) re-entry navigation support; (5) facilitated care and treatment access; and (6) management of significant barriers, such as depression. CONCLUSIONS: While preliminary, the identified trajectories may guide interventions to support re-engagement, such as offering flexible ART access to patients with intermittent engagement patterns instead of stable patients only. Further, for re-engagement interventions to achieve impact, they must activate mechanisms underlying re-engagement behaviours. For example, facility outreach that reminds a patient to return to care but does not affirm a patient's value or navigate re-entry is unlikely to be effective. The demonstrated importance of positive health facility connections reinforces a growing call for patient-centred care. Additionally, interventions should consider the important role communities play in fostering treatment motivation and overcoming practical barriers.
