HIV testing and linkage to ART following secondary distribution of HIV self‐test kits to male partners of women living with HIV: a pilot randomized control trial in Mpumalanga,South Africa

IntroductionSouth African men are underrepresented in HIV testing and treatment services. Secondary distribution of oral HIV self‐test (HIVST) kits by women living with HIV (WLHIV) to their male partners (i.e. index partner HIVST) may increase men''s testing and treatment but has been understudied.MethodsBetween March and July 2021, we evaluated the effectiveness of index partner HIVST versus the standard of care (SOC) (invitations for men''s facility‐based testing) on men''s testing in a 1:1 randomized control trial. Eligibility criteria included: WLHIV; ≥18 years of age; attending one of four high‐density rural clinics; have a working cell phone; and self‐reported having a primary male partner of unknown serostatus. The primary outcome was the proportion of WLHIV reporting that her partner tested for HIV within 3 months after enrolment.ResultsWe enrolled 180 WLHIV and 176 completed an endline survey (mean age = 35 years, 15% pregnant, 47% unmarried or non‐cohabiting). In the HIVST arm, 78% of male partners were reported to have tested for HIV versus 55% in SOC (RR = 1.41; 95% CI = 1.14–1.76). In the HIVST arm, nine men were reactive with HIVST (14% positivity), six were confirmed HIV positive with standard testing (67%) and all of those started antiretroviral therapy (ART), and four HIV‐negative men started pre‐exposure prophylaxis (PrEP) (5%). In SOC, six men were diagnosed with HIV (12% positivity), 100% started ART and seven HIV‐negative men started PrEP (16%). One case of verbal intimate partner violence was reported in the HIVST arm.ConclusionsSecondary distribution of HIVST to partners of WLHIV was acceptable and effective for improving HIV testing among men in rural South Africa in our pilot study. Interventions are needed to link reactive HIVST users to confirmatory testing and ART.     

Towards the first 90: impact of the national HIV self‐test program on case finding and factors associated with linkage to confirmatory diagnosis in Taiwan

IntroductionBeing aware of one''s HIV‐positive status can help reduce unprotected sex and promote early treatment seeking. Therefore, HIV self‐test (HIVST) programs may help control the HIV epidemic by case finding. The aims of this study were to determine the effect of HIVST programs on HIV case finding, time to confirmatory diagnosis and factors associated with linkage to confirmatory diagnosis in Taiwan.MethodsThe Centers for Disease Control in Taiwan initiated HIVST programs and imported 78,000 self‐test kits in 2017 and 2019. Clients paid 7 US dollars for a self‐test kit at facilities, vending machines or online. The programs set up an HIVST logistics management system; each kit had a unique barcode for monitoring the programs because purchases were anonymous. When clients provided their test results with photo barcodes online or at HIV/AIDS‐designated hospitals, they received full monetary reimbursement. We conducted a quasi‐experimental interrupted time‐series (ITS) analysis that covered a period of 60 months from 2015 to 2019. We enrolled a retrospective cohort of reported HIV cases with initial positive results from HIVST programs between March 2017 and July 2020.ResultsThe ITS analysis included data from 10,976 reported HIV cases from 2015 to 2019. The HIVST‐positive cohort included 386 reported HIV cases, of whom 99.7% were males and 97% were men who have sex with men (MSM); the median age was 28 years. The ITS analysis showed a positive slope change in the number of reported HIV cases immediately in the beginning implementation month (coefficient: 51.09 in 2017 and 3.62 in 2019), but there was a significant decrease over time. It was a negative slope change by 9.52 cases per month in 2017 and 5.56 cases per month in 2019. In the HIVST‐positive cohort, three of five individuals linked to HIV confirmatory diagnosis within 1 month after a positive self‐test result, and an early linkage to confirmatory diagnosis was associated with HIVST disclosure (adjusted OR = 6.5; 95% CI: 3.9–10.6).ConclusionsHIVST programs were associated with an increase in HIV case finding. Our findings suggest that countries with a high incidence of HIV among MSM populations should offer multichannel HIVST services.     

HIV self‐testing partially filled the HIV testing gap among men who have sex with men in China during the COVID‐19 pandemic: results from an online survey

IntroductionHIV self‐testing (HIVST) is a useful strategy to promote HIV testing among key populations. This study aimed to understand HIV testing behaviours among men who have sex with men (MSM) and specifically how HIVST was used during the coronavirus disease 2019 (COVID‐19) measures in China when access to facility‐based testing was limited.MethodsAn online cross‐sectional study was conducted to recruit men who have sex with men (MSM) in China from May to June of 2020, a period when COVID‐19 measures were easing. Data on socio‐demographic characteristics, sexual behaviours and HIV testing in the three months before and during COVID‐19 measures (23 January 2020) were collected. Chi‐square test and logistic regression were used for analyses.ResultsOverall, 685 MSM were recruited from 135 cities in 30 provinces of China, whose mean age was 28.8 (SD: 6.9) years old. The majority of participants self‐identified as gay (81.9%) and had disclosed their sexual orientation (66.7%). In the last three months, 69.6% ever had sex with men, nearly half of whom had multiple sexual partners (47.2%). Although the overall HIV testing rates before and during COVID‐19 measures were comparable, more MSM self‐tested for HIV during COVID‐19 measures (52.1%) compared to before COVID‐19 measures (41.6%, p = 0.038). Fewer MSM used facility‐based HIV testing during COVID‐19 measures (42.9%) compared to before COVID‐19 measures (54.1%, p = 0.038). Among 138 facility‐based testers before COVID‐19 measures, 59.4% stopped facility‐based testing during COVID‐19 measures. Among 136 self‐testers during COVID‐19 measures, 58.1% had no HIV self‐testing before COVID‐19 measures. Multivariable logistic regression showed that having sex with other men in the last three months (adjusted odds ratio, aOR = 2.04, 95% CI: 1.38 to 3.03), self‐identifying as gay (aOR = 2.03, 95% CI: 1.31 to 3.13), ever disclosing their sexual orientation (aOR = 1.72, 95% CI: 1.19 to 2.50) and tested for HIV in three months before COVID‐19 measures (aOR = 4.74, 95% CI: 3.35 to 6.70) were associated with HIV testing during COVID‐19 measures.ConclusionsFacility‐based HIV testing decreased and HIVST increased among MSM during COVID‐19 measures in China. MSM successfully accessed HIVST as substitute for facility‐based testing, with no overall decrease in HIV testing rates.     

The impact of disruptions due to COVID‐19 on HIV transmission and control among men who have sex with men in China

IntroductionThe COVID‐19 pandemic is impacting HIV care globally, with gaps in HIV treatment expected to increase HIV transmission and HIV‐related mortality. We estimated how COVID‐19‐related disruptions could impact HIV transmission and mortality among men who have sex with men (MSM) in four cities in China, over a one‐ and five‐year time horizon.MethodsRegional data from China indicated that the number of MSM undergoing facility‐based HIV testing reduced by 59% during the COVID‐19 pandemic, alongside reductions in ART initiation (34%), numbers of all sexual partners (62%) and consistency of condom use (25%), but initial data indicated no change in viral suppression. A mathematical model of HIV transmission/treatment among MSM was used to estimate the impact of disruptions on HIV infections/HIV‐related deaths. Disruption scenarios were assessed for their individual and combined impact over one and five years for 3/4/6‐month disruption periods, starting from 1 January 2020.ResultsOur model predicted new HIV infections and HIV‐related deaths would be increased most by disruptions to viral suppression, with 25% reductions (25% virally suppressed MSM stop taking ART) for a three‐month period increasing HIV infections by 5% to 14% over one year and deaths by 7% to 12%. Observed reductions in condom use increased HIV infections by 5% to 14% but had minimal impact (<1%) on deaths. Smaller impacts on infections and deaths (<3%) were seen for disruptions to facility HIV testing and ART initiation, but reduced partner numbers resulted in 11% to 23% fewer infections and 0.4% to 1.0% fewer deaths. Longer disruption periods (4/6 months) amplified the impact of disruption scenarios. When realistic disruptions were modelled simultaneously, an overall decrease in new HIV infections occurred over one year (3% to 17%), but not for five years (1% increase to 4% decrease), whereas deaths mostly increased over one year (1% to 2%) and five years (1.2 increase to 0.3 decrease).ConclusionsThe overall impact of COVID‐19 on new HIV infections and HIV‐related deaths is dependent on the nature, scale and length of the various disruptions. Resources should be directed to ensuring levels of viral suppression and condom use are maintained to mitigate any adverse effects of COVID‐19‐related disruption on HIV transmission and control among MSM in China.     

Two years after lockdown: reviewing the effects of COVID‐19 on health services and support for adolescents living with HIV in South Africa

IntroductionSouth Africa''s progress towards the 95‐95‐95 goals has been significantly slower among adolescents living with HIV (ALHIV), among whom antiretroviral therapy (ART) adherence, retention in care and viral suppression remain a concern. After 2 years of living with COVID‐19, it is important to examine the direct and indirect effects of the pandemic on healthcare resources, access to HIV services and availability of support structures, to assess their impact on HIV care for ALHIV.DiscussionThe COVID‐19 response in South Africa has shifted healthcare resources towards combatting COVID‐19, affecting the quality and availability of HIV services—especially for vulnerable populations, such as ALHIV. The healthcare system''s response to COVID‐19 has threatened to diminish fragile gains in engaging ALHIV with HIV services, especially as this group relies on overburdened public health facilities for their HIV care. Reallocation of limited health resources utilized by ALHIV disrupted healthcare workers’ capacity to form and maintain therapeutic relationships with ALHIV and monitor ALHIV for ART‐related side effects, treatment difficulties and mental health conditions, affecting their ability to retain ALHIV in HIV care. Prevailing declines in HIV surveillance meant missed opportunities to identify and manage opportunistic infections and HIV disease progression in adolescents. “Lockdown” restrictions have limited access to healthcare facilities and healthcare workers for ALHIV by reducing clinic appointments and limiting individual movement. ALHIV have had restricted access to social, psychological and educational support structures, including national feeding schemes. This limited access, coupled with reduced opportunities for routine maternal and sexual and reproductive health services, may place adolescent girls at greater risk of transactional sex, child marriages, unintended pregnancy and mother‐to‐child HIV transmission.ConclusionsAdolescent HIV care in South Africa is often overlooked; however, ART adherence among ALHIV in South Africa is particularly susceptible to the consequences of a world transformed by COVID‐19. The current structures in place to support HIV testing, ART initiation and adherence have been reshaped by disruptions to health structures, new barriers to access health services and the limited available education and psychosocial support systems. Reflecting on these limitations can drive considerations for minimizing these barriers and retaining ALHIV in HIV care.     

Partner testing with HIV self-test distribution by Ugandan pregnant women living with HIV: a randomized trial

Introduction

Secondary distribution of HIV self-tests (HIVST) by HIV-negative pregnant women to male partners increases men's testing rates. We examined whether this strategy promotes male partner testing for pregnant women living with HIV (PWLHIV).

Methods

We conducted an open-label individually randomized trial in Kampala, Uganda, in which PWLHIV ≥18 years who reported a partner of unknown HIV status were randomized 2:1 to secondary distribution of HIVST for male partner(s) or standard-of-care (SOC; invitation letter to male partner for fast-track testing). Women were followed until 12 months post-partum. Male partners were offered confirmatory HIV testing and facilitated linkage to antiretroviral treatment (ART) or oral pre-exposure prophylaxis (PrEP). Using intention-to-treat analysis, primary outcomes were male partner testing at the clinic and initiation on PrEP or ART evaluated through 12 months post-partum (ClinicalTrials.gov, NCT03484533).

Results

From November 2018 to March 2020, 500 PWLHIV were enrolled with a median age of 27 years (interquartile range [IQR] 23–30); 332 were randomized to HIVST and 168 to SOC with 437 PWLHIV (87.4%) completing 12 months follow-up post-partum. Of 236 male partners who tested at the clinic and enrolled (47.2%), their median age was 31 years (IQR 27–36), 45 (88.3%) men with HIV started ART and 113 (61.1%) HIV-negative men started PrEP. There was no intervention effect on male partner testing (hazard ratio [HR] 1.04; 95% confidence interval [CI]: 0.79–1.37) or time to ART or PrEP initiation (HR 0.96; 95% CI: 0.69–1.33). Two male partners and two infants acquired HIV for an incidence of 0.99 per 100 person-years (95% CI: 0.12–3.58) and 1.46 per 100 person-years (95% CI: 0.18%–5.28%), respectively. Social harms related to study participation were experienced by six women (HIVST = 5, SOC = 1).

Conclusions

Almost half of the partners of Ugandan PWLHIV tested for HIV with similar HIV testing rates and linkage to ART or PrEP among the secondary distribution of HIVST and SOC arms. Although half of men became aware of their HIV serostatus and linked to services, additional strategies to reach male partners of women in antenatal care are needed to increase HIV testing and linkage to services among men.     

Antiretroviral therapy and Kaposi’s sarcoma trends and outcomes among adults with HIV in Latin America

IntroductionKaposi’s sarcoma (KS) remains the most frequent malignancy in persons living with HIV (PWH) in Latin America. We examined KS trends and outcomes from Latin American clinical sites in the era of increased access to antiretroviral therapy (ART).MethodsCohorts in Brazil, Peru, Mexico, Honduras, Argentina and Chile contributed clinical data of PWH ≥16 years old from 2000 to 2017, excluding patients with KS diagnosed before clinic enrolment. We compared KS incidence over time using multivariable incidence rate ratios. Predictors of KS before/at or after ART initiation and of mortality after KS were examined using Cox regression.ResultsOf 25 981 PWH, 481 had incident KS, including 200 ART‐naïve and 281 ART‐treated patients. From 2000 to 2017, the incidence of KS decreased from 55.1 to 3.0 per 1000 person‐years. In models adjusting for CD4 and other factors, the relative risk for KS decreased from 2000 to 2008. Since 2010, the adjusted risk of KS increased in the periods before and ≤90 days after ART initiation but decreased >90 days after ART. In addition to low CD4 and male‐to‐male sex, KS risk after ART was associated with age and history of other AIDS‐defining illnesses. Mortality after KS (approximately 25% after five years) was not associated with either year of KS diagnosis nor timing of diagnosis relative to ART initiation.ConclusionsKS incidence in Latin America has remained stable in recent years and risk is highest before and shortly after ART initiation. Early diagnosis of HIV and ART initiation remain critical priorities in the region.     

Acceleration of differentiated service delivery for HIV treatment in sub‐Saharan Africa during COVID‐19

IntroductionIn response to COVID‐19, national ministries of health adapted HIV service delivery guidelines to ensure uninterrupted access to antiretroviral therapy (ART) and limit the frequency of contact with health facilities. In this commentary, we summarize four ways in which differentiated service delivery (DSD) for HIV treatment has been accelerated during COVID‐19 in policy and implementation in sub‐Saharan Africa (SSA) – (i) expanding eligibility for DSD for HIV treatment, (ii) extending multi‐month dispensing (MMD) and reducing the frequency of clinical consultations, (iii) emphasizing community‐based models and (iv) integrating/aligning with TB preventative therapy (TPT), non‐communicable disease (NCD) treatments and family planning commodities.DiscussionAcross SSA in 2020, countries both adapted and emphasized policies supporting DSD for HIV treatment in response to COVID‐19. Access to DSD for HIV treatment was expanded by reducing the time required on ART before eligibility and being more inclusive of specific populations including children and adolescents, pregnant and breastfeeding women and those on second‐ and third‐line regimens. Access to extended ART refills, or MMD, was accelerated across many countries. A renewed focus was given to out‐of‐facility community‐based models of ART distribution. In some settings, there was acknowledgement of the need to integrate or align other chronic medications with ART.ConclusionsAdaptations to DSD for HIV treatment in response to COVID‐19 have resulted in rapid policy change and in some cases, acceleration of implementation in SSA. As the COVID‐19 pandemic evolves, there is a critical need to assess the impact of these adaptations and, where beneficial, ensure that policies implemented in response to COVID‐19 become the new normal.     

Optimizing infant HIV diagnosis with additional screening at immunization clinics in three sub‐Saharan African settings: a cost‐effectiveness analysis

IntroductionUptake of early infant HIV diagnosis (EID) varies widely across sub‐Saharan African settings. We evaluated the potential clinical impact and cost‐effectiveness of universal maternal HIV screening at infant immunization visits, with referral to EID and maternal antiretroviral therapy (ART) initiation.MethodsUsing the CEPAC‐Pediatric model, we compared two strategies for infants born in 2017 in Côte d’Ivoire (CI), South Africa (SA), and Zimbabwe: (1) existing EID programmes offering six‐week nucleic acid testing (NAT) for infants with known HIV exposure (EID), and (2) EID plus universal maternal HIV screening at six‐week infant immunization visits, leading to referral for infant NAT and maternal ART initiation (screen‐and‐test). Model inputs included published Ivoirian/South African/Zimbabwean data: maternal HIV prevalence (4.8/30.8/16.1%), current uptake of EID (40/95/65%) and six‐week immunization attendance (99/74/94%). Referral rates for infant NAT and maternal ART initiation after screen‐and‐test were 80%. Costs included NAT ($24/infant), maternal screening ($10/mother–infant pair), ART ($5 to 31/month) and HIV care ($15 to 190/month). Model outcomes included mother‐to‐child transmission of HIV (MTCT) among HIV‐exposed infants, and life expectancy (LE) and mean lifetime per‐person costs for children with HIV (CWH) and all children born in 2017. We calculated incremental cost‐effectiveness ratios (ICERs) using discounted (3%/year) lifetime costs and LE for all children. We considered two cost‐effectiveness thresholds in each country: (1) the per‐capita GDP ($1720/6380/2150) per year‐of‐life saved (YLS), and (2) the CEPAC‐generated ICER of offering 2 versus 1 lifetime ART regimens (e.g. offering second‐line ART; $520/500/580/YLS).ResultsWith EID, projected six‐week MTCT was 9.3% (CI), 4.2% (SA) and 5.2% (Zimbabwe). Screen‐and‐test decreased total MTCT by 0.2% to 0.5%, improved LE by 2.0 to 3.5 years for CWH and 0.03 to 0.07 years for all children, and increased discounted costs by $17 to 22/child (all children). The ICER of screen‐and‐test compared to EID was $1340/YLS (CI), $650/YLS (SA) and $670/YLS (Zimbabwe), below the per‐capita GDP but above the ICER of 2 versus 1 lifetime ART regimens in all countries.ConclusionsUniversal maternal HIV screening at immunization visits with referral to EID and maternal ART initiation may reduce MTCT, improve paediatric LE, and be of comparable value to current HIV‐related interventions in high maternal HIV prevalence settings like SA and Zimbabwe.     

Closing the gap: did delivery approaches complementary to home‐based testing reach men with HIV testing services during and after the HPTN 071 (PopART) trial in Zambia?

IntroductionThe HPTN 071 (PopART) trial demonstrated that universal HIV testing‐and‐treatment reduced community‐level HIV incidence. Door‐to‐door delivery of HIV testing services (HTS) was one of the main components of the intervention. From an early stage, men were less likely to know their HIV status than women, primarily because they were not home during service delivery. To reach more men, different strategies were implemented during the trial. We present the relative contribution of these strategies to coverage of HTS and the impact of community hubs implemented after completion of the trial among men.MethodsBetween 2013 and 2017, three intervention rounds (IRs) of door‐to‐door HTS delivery were conducted in eight PopART communities in Zambia. Additional strategies implemented in parallel, included: community‐wide “Man‐up” campaigns (IR1), smaller HTS campaigns at work/social places (IR2) and revisits to households with the option of HIV self‐testing (HIVST) (IR3). In 2018, community “hubs” offering HTS were implemented for 7 months in all eight communities. Population enumeration data for each round of HTS provided the denominator, allowing for calculation of the proportion of men tested as a result of each strategy during different time periods.ResultsBy the end of the three IRs, 65–75% of men were reached with HTS, primarily through door‐to‐door service delivery. In IR1 and IR2, “Man‐up” and work/social place campaigns accounted for ∼1 percentage point each and in IR3, revisits with the option of self‐testing for ∼15 percentage points of this total coverage per IR. The yield of newly diagnosed HIV‐positive men ranged from 2.2% for HIVST revisits to 9.9% in work/social places. At community hubs, the majority of visitors accepting services were men (62.8%). In total, we estimated that ∼36% (2.2% tested HIV positive) of men resident but not found at their household during IR3 of PopART accessed HTS provided at the hubs after trial completion.ConclusionsAchieving high coverage of HTS among men requires universal, home‐based service delivery combined with an option of HIVST and delivery of HTS through community‐based hubs. When men are reached, they are willing to test for HIV. Reaching men thus requires implementers to adapt their HTS delivery strategies to meet men''s needs.Clinical Trial Number{"type":"clinical-trial","attrs":{"text":"NCT01900977","term_id":"NCT01900977"}}NCT01900977     

Cognitive outcomes at ages seven and nine years in South African children from the children with HIV early antiretroviral (CHER) trial: a longitudinal investigation

IntroductionMany children living with HIV (CLWH) display impaired cognition. Although early combination antiretroviral therapy (ART) produces improved cognitive outcomes, more long‐term outcome data are needed. After concluding the Children with HIV Early antiRetroviral (CHER) trial in 2011, we investigated cognitive performance, at seven and nine years of age. Participants had been randomized to deferred ART (ART‐Def; n = 22); immediate time‐limited ART for 40 weeks (ART‐40W; n = 30) and immediate time‐limited ART for 96 weeks (ART‐96W; n = 18). We also recruited HIV‐exposed uninfected (CHEU; n = 28) and HIV‐unexposed (CHU; n = 35) children.MethodsData were collected between May 2012 and December 2017. Mixed‐model repeated‐measures ANOVAs assessed differences over time between CLWH (ART‐40W, ART‐96W and ART‐Def) and CHIV‐ CHEU and CHU between ART‐Early (ART‐40W and ART‐96W), ART‐Def, CHEU and CHU; and between ART‐40W, ART‐96W, ART‐Def, CHEU and CHU.ResultsAll comparisons found significant effects of Time for most outcome variables (better scores at nine than at seven years; ps < 0.05). The first ANOVAs found that for (a) motor dexterity, CLWH performed worse than CHIV‐ at seven years (p < 0.001) but improved to equivalence at nine years, (b) visual‐spatial processing and problem solving, only CLWH (p < 0.04) showed significant performance improvement over time and (c) working memory and executive function, CLWH performed worse than CHIV‐ at both seven and nine years (p = 0.03 and 0.04). The second ANOVAs found that for (a) working memory, CHU performed better than ART‐Early and CHEU (p < 0.01 and <0.04), and (b) motor dexterity, ART‐Def performed worse than ART‐Early, CHEU and CHU at seven years (p = 0.02, <0.001 and <0.001 respectively) but improved to equivalence at nine years (ps > 0.17). Similarly, for motor dexterity, ART‐Def performed worse than ART‐96W, CHEU and CHU at seven years (p < 0.04, <0.001 and <0.001) but improved to equivalence at nine years (ps > 0.20).ConclusionsAlthough neurocognitive developmental trajectories for treatment groups and controls were largely similar (i.e. performance improvements from 7 to 9), all ART‐treated children, regardless of treatment arm, remain at risk for cognitive deficits over early school ages. Although the nature of these deficits may change as cognitive development proceeds, there are potential negative consequences for these children’s future learning, reasoning and adaptive functioning.     

Improved detection and management of advanced HIV disease through a community adult TB‐contact tracing intervention with same‐day provision of the WHO‐recommended package of care including ART initiation in a rural district of Mozambique

IntroductionAIDS‐mortality remains unacceptably high in sub‐Saharan Africa, largely driven by advanced HIV disease (AHD). We nested a study in an existing tuberculosis (TB) contact‐tracing intervention (Xpatial‐TB). The aim was to assess the burden of AHD among high‐risk people living with HIV (PLHIV) identified and to evaluate the provision of the WHO‐recommended package of care to this population.MethodsAll PLHIV ≥14 years old identified between June and December 2018 in Manhiça District by Xpatial‐TB were offered to participate in the study if ART naïve or had suboptimal ART adherence. Consenting individuals were screened for AHD. Patients with AHD (CD4 < 200 cells/μL or WHO stage 3 or 4) were offered a package of interventions in a single visit, including testing for cryptococcal antigen (CrAg) and TB‐lipoarabinomannan (TB‐LAM), prophylaxis and treatment for opportunistic infections, adherence support or accelerated ART initiation. We collected information on follow‐up visits carried out under routine programmatic conditions for six months.ResultsA total of 2881 adults were identified in the Xpatial TB‐contact intervention. Overall, 23% (673/2881) were HIV positive, including 351 TB index (64.2%) and 322 TB contacts (13.8%). Overall, 159/673 PLHIV (24%) were ART naïve or had suboptimal ART adherence, of whom 155 (97%, 124 TB index and 31 TB‐contacts) consented to the study and were screened for AHD. Seventy percent of TB index‐patients (87/124) and 16% of TB contacts (5/31) had CD4 < 200 cells/µL. Four (13%) of the TB contacts had TB, giving an overall AHD prevalence among TB contacts of 29% (9/31). Serum‐CrAg was positive in 4.6% (4/87) of TB‐index patients and in zero TB contacts. All ART naïve TB contacts without TB initiated ART within 48 hours of HIV diagnosis. Among TB cases, ART timing was tailored to the presence of TB and cryptococcosis. Six‐month mortality was 21% among TB‐index cases and zero in TB contacts.ConclusionsA TB contact‐tracing outreach intervention identified undiagnosed HIV and AHD in TB patients and their contacts, undiagnosed cryptococcosis among TB patients, and resulted in an adequate provision of the WHO‐recommended package of care in this rural Mozambican population. Same‐day and accelerated ART initiation was feasible and safe in this population including among those with AHD.     

Timing of HIV testing among pregnant and breastfeeding women and risk of mother‐to‐child HIV transmission in Malawi: a sampling‐based cohort study

IntroductionPregnant women living with HIV can achieve viral suppression and prevent HIV mother‐to‐child transmission (MTCT) with timely HIV testing and early ART initiation and maintenance. Although it is recommended that pregnant women undergo HIV testing early in antenatal care in Malawi, many women test positive during breastfeeding because they did not have their HIV status ascertained during pregnancy, or they tested negative during pregnancy but seroconverted postpartum. We sought to estimate the association between the timing of last positive HIV test (during pregnancy vs. breastfeeding) and outcomes of maternal viral suppression and MTCT in Malawi’s PMTCT programme.MethodsWe conducted a two‐stage cohort study among mother–infant pairs in 30 randomly selected high‐volume health facilities across five nationally representative districts of Malawi between 1 July 2016 and 30 June 2017. Log‐binomial regression was used to estimate prevalence ratios (PR) and risk ratios (RR) for associations between timing of last positive HIV test (i.e. breastfeeding vs. pregnancy) and maternal viral suppression and MTCT, controlling for confounding using inverse probability weighting.ResultsOf 822 mother–infant pairs who had available information on the timing of the last positive HIV test, 102 mothers (12.4%) had their last positive test during breastfeeding. Women who lived one to two hours (PR = 2.15; 95% CI: 1.29 to 3.58) or >2 hours (PR = 2.36; 95% CI: 1.37 to 4.10) travel time to the nearest health facility were more likely to have had their last positive HIV test during breastfeeding compared to women living <1 hour travel time to the nearest health facility. The risk of unsuppressed VL did not differ between women who had their last positive HIV test during breastfeeding versus pregnancy (adjusted RR [aRR] = 0.87; 95% CI: 0.48 to 1.57). MTCT risk was higher among women who had their last positive HIV test during breastfeeding compared to women who had it during pregnancy (aRR = 6.57; 95% CI: 3.37 to 12.81).ConclusionsMTCT in Malawi occurred disproportionately among women with a last positive HIV test during breastfeeding. Testing delayed until the postpartum period may lead to higher MTCT. To optimize maternal and child health outcomes, PMTCT programmes should focus on early ART initiation and providing targeted testing, prevention, treatment and support to breastfeeding women.     

The efficacy and cost‐effectiveness of a family‐based economic empowerment intervention (Suubi + Adherence) on suppression of HIV viral loads among adolescents living with HIV: results from a Cluster Randomized Controlled Trial in southern Uganda

IntroductionEvidence from low‐resource settings indicates that economic insecurity is a major barrier to HIV treatment adherence. Economic empowerment (EE) interventions have the potential to improve adherence outcomes among adolescents living with HIV (ALWHIV) by mitigating the effects of poverty. This study aims to assess the efficacy and cost‐effectiveness of a savings‐led family‐based EE intervention, Suubi + Adherence, aimed at improving antiretroviral therapy (ART) adherence outcomes ALWHIV in Uganda.MethodsAdolescents (mean age 12 years at enrolment; 56% female) receiving ART for HIV at 39 health centres were randomized to Suubi + Adherence intervention (n = 358) or bolstered standard of care (BSOC; n = 344). A difference‐in‐differences analysis was employed to assess the change in the proportion of virally suppressed adolescents (HIV RNA viral load <40 copies/mL) over 24 months. The cost‐effectiveness analysis examined how much the intervention cost to virally suppress one additional adolescent relative to BSOC from the healthcare provider perspective.ResultsAt 24 months, the intervention was associated with an 8.85‐percentage point [95% confidence interval (CI) 0.80 to 16.90 percentage points] increase in the proportion of virally suppressed adolescents between the study arms (p = 0.032). Per‐participant costs were US$177 and US$263 for the BSOC and intervention groups respectively. The incremental cost of virally suppressing one additional adolescent was estimated at US$970 [95% CI, US$508 to 10,725] over two years.ConclusionsOur results support the integration of family‐based EE interventions into adherence‐support strategies as part of routine HIV care in low‐resource settings to address the underlying economic drivers of poor ART adherence among ALWHIV. Moreover, per‐participant costs to achieve viral suppression do not seem prohibitive compared to other community‐based adherence interventions targeted at ALWHIV in low‐resource settings. Further research on combination interventions at the nexus of economic security and HIV treatment and care is needed to inform the development of feasible and scalable HIV policies and programmes.     

HIV treatment outcomes among people who acquired HIV via injecting drug use in the Asia‐Pacific region: a longitudinal cohort study

INTRODUCTIONData on HIV treatment outcomes in people who inject drugs (PWID) in the Asia‐Pacific are sparse despite the high burden of drug use. We assessed immunological and virological responses, AIDS‐defining events and mortality among PWID receiving antiretroviral therapy (ART).METHODSWe investigated HIV treatment outcomes among people who acquired HIV via injecting drug use in the TREAT Asia HIV Observational Database (TAHOD) between January 2003 and March 2019. Trends in CD4 count and viral suppression (VS, HIV viral load <1000 copies/mL) were assessed. Factors associated with mean CD4 changes were analysed using repeated measures linear regression, and combined AIDS event and mortality were analysed using survival analysis.RESULTSOf 622 PWID from 12 countries in the Asia‐Pacific, 93% were male and the median age at ART initiation was 31 years (IQR, 28 to 34). The median pre‐ART CD4 count was 71 cells/µL. CD4 counts increased over time, with a mean difference of 401 (95% CI, 372 to 457) cells/µL at year‐10 (n = 78). Higher follow‐up HIV viral load and pre‐ART CD4 counts were associated with smaller increases in CD4 counts. Among 361 PWID with ≥1 viral load after six months on ART, proportions with VS were 82%, 88% and 93% at 2‐, 5‐ and 10‐years following ART initiation. There were 52 new AIDS‐defining events and 50 deaths during 3347 person‐years of follow‐up (PYS) (incidence 3.05/100 PYS, 95% CI, 2.51 to 3.70). Previous AIDS or TB diagnosis, lower current CD4 count and adherence <95% were associated with combined new AIDS‐defining event and death.CONCLUSIONSDespite improved outcomes over time, our findings highlight the need for rapid ART initiation and adherence support among PWID within Asian settings.     

Trends in demographic and clinical characteristics and initiation of antiretroviral therapy among adult patients enrolling in HIV care in the Central Africa International epidemiology Database to Evaluate AIDS (CA‐IeDEA) 2004 to 2018

IntroductionThe Central Africa International epidemiology Database to Evaluate AIDS (CA‐IeDEA) is an open observational cohort study investigating impact, progression and long‐term outcomes of HIV/AIDS among people living with HIV (PLWH) in Burundi, Cameroon, Democratic Republic of Congo (DRC), Republic of Congo (ROC) and Rwanda. We describe trends in demographic, clinical and immunological characteristics as well as antiretroviral therapy (ART) use of patients aged > 15 years entering into HIV care in the participating CA‐IeDEA site.MethodsInformation on sociodemographic characteristics, height, weight, body mass index (BMI), CD4 cell count, WHO staging and ART status at entry into care from 2004 through 2018 were extracted from clinic records of patients aged > 15 years enrolling in HIV care at participating clinics in Burundi, Cameroon, DRC, ROC and Rwanda. We assessed trends in patient characteristics at enrolment in HIV care including ART initiation within the first 30 days after enrolment in care and calculated proportions, means and medians (interquartile ranges) for the main variables of interest.ResultsAmong 69,176 patients in the CA‐IeDEA cohort, 39% were from Rwanda, 24% from ROC, 18% from Cameroon, 14% from Burundi and 5% from DRC. More women (66%) than men enrolled in care and subsequently initiated ART. Women were also younger than men (32 vs. 38 years, P < 0.001) at enrolment and at ART initiation. Trends over time show increases in median CD4 cell count at enrolment from 190 cells/µL in 2004 to 334 cells/µL in 2018 at enrolment. Among those with complete data on CD4 counts (60%), women had a higher median CD4 cell count at care entry than men (229 vs. 249 cells/µL, P < 0.001). Trends in the proportion of patients using ART within 30 days of enrolment at the participating site show an increase from 16% in 2004 to 75% in 2018.ConclusionsTrends from 2004 to 2018 in the characteristics of patients participating in the CA‐IeDEA cohort highlight improvements at entry into care and subsequent ART initiation including after the implementation of Treat All guidelines in the participating sites.     

Do not forget the children: a model‐based analysis on the potential impact of COVID‐19‐associated interruptions in paediatric HIV prevention and care

IntroductionThe COVID‐19 pandemic has affected women and children globally, disrupting antiretroviral therapy (ART) services and exacerbating pre‐existing barriers to care for both pregnant women and paediatric populations.MethodsWe used the Spectrum modelling package and the CEPAC‐Pediatric model to project the impact of COVID‐19‐associated care disruptions on three key populations in the 21 Global Plan priority countries in sub‐Saharan Africa: (1) pregnant and breastfeeding women living with HIV and their children, (2) all children (aged 0–14 years) living with HIV (CLWH), regardless of their engagement in care and (3) CLWH who were engaged in care and on ART prior to the start of the pandemic. We projected clinical outcomes over the 12‐month period of 1 March 2020 to 1 March 2021.ResultsCompared to a scenario with no care disruption, in a 3‐month lockdown with complete service disruption, followed by 3 additional months of partial (50%) service disruption, a projected 755,400 women would have received PMTCT care (a 21% decrease), 187,800 new paediatric HIV infections would have occurred (a 77% increase) and 516,800 children would have received ART (a 35% decrease). For children on ART as of March 2020, we projected 507,200 would have experienced ART failure (an 80% increase). Additionally, a projected 88,400 AIDS‐related deaths would have occurred (a 27% increase) between March 2020 and March 2021, with 51,700 of those deaths occurring among children engaged in care as of March 2020 (a 54% increase).ConclusionsWhile efforts will continue to curb morbidity and mortality stemming directly from COVID‐19 itself, it is critical that providers also consider the immediate and indirect harms of this pandemic, particularly among vulnerable populations. Well‐informed, timely action is critical to meet the health needs of pregnant women and children if the global community is to maintain momentum towards an AIDS‐free generation.
