Lower Insulin Sensitivity Through 36 Months of Life With in Utero HIV and Antiretroviral Exposure in Botswana: Results From the Tshilo Dikotla Study.

BACKGROUND: There are little data on changes in insulin sensitivity during the first few years of life following in utero human immunodeficiency virus (HIV) and antiretroviral (ARV) exposure. METHODS: The Tshilo Dikotla study enrolled pregnant persons with HIV (PWH) (receiving tenofovir/emtricitabine or lamivudine plus dolutegravir or efavirenz) and pregnant individuals without HIV, as well as their liveborn children. Newborns were randomized to receive either zidovudine (AZT) or nevirapine (NVP) postnatal prophylaxis. Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) was assessed at birth and 1, 18, 24, and 36 months of life. We fit linear mixed-effects models to evaluate the association between in utero HIV/ARV exposure and average HOMA-IR from birth through 36 months of life, adjusting for confounders. RESULTS: A total of 419 children were included (287 with in utero HIV/ARV exposure and uninfected [CHEU] and 132 without in utero HIV/ARV exposure [CHUU]). CHEU were born to older women (29.6 vs 25.3 years of age) with higher gravidity (3 vs 1). HOMA-IR was persistently higher in CHEU versus CHUU in adjusted analyses (mean difference of 0.07 in log10 HOMA-IR, P  = .02) from birth through 36 months of life. Among CHEU, no differences in HOMA-IR were observed from birth through 36 months by in utero ARV exposure status or between AZT and NVP infant prophylaxis arms. CONCLUSIONS: In utero HIV/ARV exposure was associated with lower insulin sensitivity throughout the first 36 months of life, indicating persistent early life metabolic disturbances which may raise concern for poorer metabolic health later in life.

Healthy dynamics of CD4 T cells may drive HIV resurgence in perinatally-infected infants on antiretroviral therapy.

In 2019 there were 490,000 children under five living with HIV. Understanding the dynamics of HIV suppression and rebound in this age group is crucial to optimizing treatment strategies and increasing the likelihood of infants achieving and sustaining viral suppression. Here we studied data from a cohort of 122 perinatally-infected infants who initiated antiretroviral treatment (ART) early after birth and were followed for up to four years. These data included longitudinal measurements of viral load (VL) and CD4 T cell numbers, together with information regarding treatment adherence. We previously showed that the dynamics of HIV decline in 53 of these infants who suppressed VL within one year were similar to those in adults. However, in extending our analysis to all 122 infants, we find that a deterministic model of HIV infection in adults cannot explain the full diversity in infant trajectories. We therefore adapt this model to include imperfect ART adherence and natural CD4 T cell decline and reconstitution processes in infants. We find that individual variation in both processes must be included to obtain the best fits. We also find that infants with faster rates of CD4 reconstitution on ART were more likely to experience resurgences in VL. Overall, our findings highlight the importance of combining mathematical modeling with clinical data to disentangle the role of natural immune processes and viral dynamics during HIV infection.

Growth Trajectories Over the First Year of Life Among Early-Treated Infants with Human Immunodeficiency Virus and Infants Who are Human Immunodeficiency Virus-Exposed Uninfected.

OBJECTIVE: To investigate the role of early antiretroviral therapy (ART) on growth trajectories of infants with human immunodeficiency virus (IHIV) in the first year of life. STUDY DESIGN: As part of a clinical trial of early ART in Johannesburg, South Africa (2015-2018), 116 IHIV diagnosed within 48 hours of birth were started on ART as soon as possible, and 80 uninfected infants born to mothers living with HIV (IHEU) were enrolled. Both groups were followed prospectively from birth through 48 weeks and growth parameters collected. The groups were compared and risk factors for poor growth investigated, in the full cohort and among IHIV separately. RESULTS: IHIV had lower mean weight-for-age Z-scores (WAZ) than IHEU at 4 and 8 weeks (-1.17 [SE:0.14] vs -0.72 [0.14], P = .035 and -1.23 [0.15] vs -0.67 [0.14], P = .012). Although there was some closing of the gap over time, means remained lower in IHIV through 48 weeks. In length-for-age Z-scores (LAZ), differences widened over time and IHIV had lower Z-scores by 48 weeks (-1.41 [0.15] vs -0.80 [0.18], P = .011). Deficits in WAZ and LAZ in IHIV vs IHEU were most marked among girls. IHIV with pre-ART viral load ≥1000 copies/ml had significantly lower weight-for-length and mid-upper arm circumference Z-scores across all time points through 48 weeks. CONCLUSIONS: IHIV on early ART had deficits in WAZ over the first 8 weeks of life and lower LAZ at 48 weeks than IHEU. Among IHIV, higher pre-ART viral load was associated with worse anthropometric indicators through 48 weeks.

Feasibility and acceptability of point of care testing for sexually transmitted infections in outpatient clinics offering integrated services in Eswatini.

BACKGROUND: Lack of point of care testing (POCT) for sexually transmitted infections (STIs) is a continuing missed opportunity in Sub-Saharan Africa. We assessed feasibility and acceptability of STI POCT in Eswatini. METHODS: STI POCT for Chlamydia trachomatis (CT) and Neisseria gonorrhoea (NG) was piloted among sexually active adults 18-45 years attending two urban outpatient clinics offering HIV services. Females were randomized 1:1 to provide urine or vaginal swab and all males provided urine samples for CT/NG testing using Cepheid CT/NG cartridges on existing GeneXpert platforms. Results were returned in-person or by telephone call. We assessed duration of procedures and participant and healthcare worker acceptability of services (5-point Likert scale), time spent on STI POCT services, and correlates of CT/NG infection. RESULTS: Of 250 adults triaged, 99% (248/250) accepted STI POCT, including 44% (109/248) people living with HIV. STI POCT procedures took a median of 3:22 hours. Most adults (90%, 224/248), received results within a day (61% same day, 29% next day). CT/NG was detected among 22% (55/248): 31/55 CT, 21/55 NG and 3/55 coinfections. Youth 18-25 years, history of any sexual intercourse, and condom-less sex within the previous 7 days were significantly associated with CT/NG detected (p < 0.05). Most adults with CT/NG were treated (51/55, 93%). Most participants were satisfied with STI POCT (217/241, 90%), and would accept again/recommend it. All 32 healthcare workers who participated were satisfied with STI POCT. CONCLUSION: STI POCT was feasible, acceptable, and identified a high prevalence of STIs, highlighting the urgent need for this testing.

"We did more than survive": lessons learned from studies of risk and resilience of young people growing up with HIV and mental health needs.

Despite advances in HIV-treatment, adolescents and young adults (AYA) with HIV (AYAHIV) face myriad challenges. They are less likely than children and older adults to be virally suppressed and are at higher risk for mental health conditions compared to their peers who do not have HIV. AYA are also developing in the context of numerous biomedical, neurocognitive, and psychosocial developmental changes. Normative challenges during this time can be exacerbated by HIV and can result in significant physical and mental health problems. Yet, many AYAHIV have shown resilience with positive assets and resources and few health or mental health problems. Historically research has had a risk-focused approach to understanding AYAHIV needs. This paper discusses the rationale for a shift from a risk-focused only approach to one that examines AYAHIV needs from both a risk and resilience perspective. This paper presents: (1) epidemiological data on AYAHIV; (2) conceptual models for understanding both risk (e.g., poverty, stress, trauma, limited resources) and resilience/protective factors (e.g., family and peer support, future orientation, problem-solving skills); (3) global data examining risk and protective factors for physical and mental health challenges; and (4) promising interventions that incorporate elements of resilience to improve overall outcomes among AYAHIV.

Why do Integrated Maternal HIV and Infant Healthcare Services work? A Secondary Analysis of a Randomised Controlled Trial in South Africa.

In a randomised trial, we found that integrated maternal HIV and infant health services through the end of breastfeeding were significantly associated with the primary outcome of engagement in HIV care and viral suppression at 12 months postpartum, compared to the standard of care. Here, we quantitatively explore potential psychosocial modifiers and mediators of this association. Our findings suggest that the intervention was significantly more effective among women experiencing an unintended pregnancy but did not improve outcomes among women reporting risky alcohol use. Although not statistically significant, our results suggest that the intervention may also be more effective among women experiencing higher levels of poverty and HIV-related stigma. We observed no definitive mediator of the intervention effect, but women allocated to integrated services reported better relationships with their healthcare providers through 12 months postpartum. These findings point to high-risk groups that may benefit the most from integrated care, as well as groups for whom these benefits are hampered and that warrant further attention in intervention development and evaluation.

Condomless Sex Among HIV-affected AYA in an Era of Undetectable = Untransmittable and Pre-exposure Prophylaxis.

Given poor adherence to treatment and prevention techniques, condomless sex jeopardizes adolescents and young adults (AYA) with perinatally-acquired HIV-infection (PHIV) or perinatal HIV-exposure who are uninfected (PHEU). We examined condomless sex and its association with PHIV-status, psychiatric disorder, and sociodemographics. Data come from a US-based study of primarily Black and Latinx AYAPHIV and AYAPHEU (N = 340). Linear regression models examined condomless sex longitudinally by PHIV-status, psychiatric trajectories, and sociodemographics. Rates of viremia (AYAPHIV) and PrEP use (AYAPHEU) were assessed. 56% of participants reported recent condomless sex, with higher prevalence among: AYAPHEU vs. AYAPHIV (24% vs. 19%, p = 0.017); Latinx vs. non-Latinx AYA (25% vs. 17%, p = 0.014); and AYA with increasing psychiatric comorbidity (44%) and consistent anxiety (23%) vs. low-level disorder (17%; p < 0.05). AYAPHIV had high rates of unsuppressed viral load and AYAPHEU limited PrEP use. Preventing condomless sex is challenging within AYAPHIV and AYAPHEU. Developing accessible combination HIV/mental health interventions is much-needed.

HIV-related stigma, disclosure and social support: experiences among young pregnant and postpartum women living with HIV in South Africa.

ABSTRACTYoung pregnant and postpartum women living with HIV (WLHIV) are at high risk of poor antiretroviral therapy (ART) outcomes, which may be driven partly by HIV-related stigma. We conducted in-depth interviews with 20 pregnant and postpartum WLHIV aged 19-24 years to understand how different forms of HIV-related stigma manifest in their lives, as well as their experiences of HIV-status disclosure and social support. Participants described profound levels of perceived stigma in their community, including gossip from other young women and judgement from older adults. Consequently, participants disclosed to a limited number of people to avoid being stigmatised, and disclosure to peers was especially uncommon. However, disclosure in certain situations was described as leading to emotional support and support for ART adherence, and disclosure to older WLHIV resulted in participants having a role model. Finally, participants expressed varied ways in which they accept, speak about, and live with their HIV diagnosis. These data provide a rich understanding of the experiences of HIV-related stigma in this population and point to the need for psychosocial interventions focussed on acceptance and coping with an HIV-positive diagnosis despite profound levels of perceived stigma, as well as navigating decisions around the targets and timing of disclosure.Trial registration: ClinicalTrials.gov identifier: NCT04036851.

Disclosure to South African children about their own HIV status over time.

Disclosure to children living with HIV (CLHIV) about their own status is associated with positive outcomes such as treatment adherence, but prior cross-sectional studies in sub-Saharan Africa report disclosure rates of <50%. This study aims to assess pediatric disclosure over time. 548 CLHIV were followed from 2/2013-4/2018 in Johannesburg, South Africa. Cumulative incidence of disclosure was calculated with Kaplan-Meier analysis, and disclosure characteristics assessed with a Cox model. By end of follow-up, cumulative disclosure was 70.3% (95% confidence interval: 60.0-79.9). Median age at disclosure was 9 years (range: 3-13). Baseline predictors of disclosure included older child age and the child having a history of going hungry. Prior to disclosure, 98.0% of caregivers who disclosed had conversed with their child about their illness or an HIV-related topic, or their child had asked about HIV, versus 88.6% of caregivers who never disclosed. While many children did not receive disclosure during this relatively large, longitudinal study of South African CLHIV, caregivers who had not yet disclosed may have been preparing to do so by discussing their child's health or HIV generally with their child. This highlights the need for clinicians to consistently support caregivers throughout the incremental disclosure process.

Mental health and ART adherence among adolescents living with HIV in Mozambique.

Little is known about the mental health needs of adolescents living with HIV (ALWH) in Mozambique, including the potential relationship between mental health challenges and poor antiretroviral treatment (ART) adherence. We examined mental health problems (anxiety, depression, post-traumatic stress disorder [PTSD] symptoms and impairment) and their association with self-reported ART adherence among ALWH ages 15-19 in Nampula, Mozambique. The associations between each mental health problem area and sub-optimal adherence were estimated using logistic regression, controlling for age, education, and social support, with interaction by gender. Males had significantly higher anxiety (5.6 vs 4.3, p = 0.01), depression (5.8 vs 4.1, p = 0.005), and PTSD (13.3 vs 9.8, p = 0.02) symptoms and impairment (1.8 vs 0.56, p<0.0001) scores than females. Proportion reporting sub-optimal adherence (65%) did not differ by gender. Higher anxiety, depression, and PTSD symptom and impairment scores were significantly associated with higher odds of sub-optimal ART adherence in males but not females. Among Mozambican ALWH, mental health problems were prevalent and two-thirds had ART adherence less than 90%. Worse mental health was associated with increased odds of sub-optimal ART adherence in males but not females. Interventions are needed to address mental health problems and improve ART adherence in Mozambican ALWH, particularly among males.

Hope for the future protects against suicidal ideation among adolescents and young adults affected by perinatal HIV.

Hope for the future has been found protective against suicidal ideation (SI) in adolescents and young adults (AYA) yet has not been examined in AYA with perinatal HIV-infection (PHIV) or AYA who were perinatally HIV-exposed but uninfected (PHEU), who are at higher risk for SI than general populations. Using data from a New York City-based longitudinal study of AYAPHIV and AYAPHEU enrolled when 9-16 years old, we examined associations between hope for the future, psychiatric disorders, and SI over time using validated measures. Generalized estimating equations were used to estimate differences in mean hope for the future scores by PHIV-status and to estimate adjusted odds ratios for associations between hope for the future and SI. AYA reported high hope for the future scores and low SI across visits, irrespective of PHIV-status. Higher hope for the future scores were associated with lower odds of SI (AOR = 0.48, 95% CI: 0.23, 0.996). Mood disorder was associated with increased odds of SI (AOR = 13.57, 95% CI: 5.11, 36.05) in a model including age, sex, follow-up, PHIV-status, mood disorder, and hope for the future. Understanding how hope can be cultivated and how it protects against SI can help to inform preventive interventions for HIV-affected AYA.

Positive attitudes toward adoption of a multi-component intervention strategy aimed at improving HIV outcomes among adolescents and young people in Nampula, Mozambique: perspectives of HIV care providers.

BACKGROUND: Service providers' attitudes toward interventions are essential for adopting and implementing novel interventions into healthcare settings, but evidence of evaluations in the HIV context is still limited. This study is part of the CombinADO cluster randomized trial (ClinicalTrials.gov NCT04930367), which is investigating the effectiveness of a multi-component intervention package (CombinADO strategy) aimed at improving HIV outcomes among adolescents and young adults living with HIV (AYAHIV) in Mozambique. In this paper we present findings on key stakeholder attitudes toward adopting study interventions into local health services. METHODS: Between September and December 2021, we conducted a cross-sectional survey with a purposive sample of 59 key stakeholders providing and overseeing HIV care among AYAHIV in 12 health facilities participating in the CombinADO trial, who completed a 9-item scale on attitudes towards adopting the trial intervention packages in health facilities. Data were collected in the pre-implementation phase of the study and included individual stakeholder and facility-level characteristics. We used generalized linear regression to examine the associations of stakeholder attitude scores with stakeholder and facility-level characteristics. RESULTS: Overall, service-providing stakeholders within this setting reported positive attitudes regarding adopting intervention packages across study clinic sites; the overall mean total attitude score was 35.0 ([SD] = 2.59, Range = [30-41]). The study package assessed (control or intervention condition) and the number of healthcare workers delivering ART care in participating clinics were the only significant explanatory variables to predict higher attitude scores among stakeholders (ß = 1.57, 95% CI = 0.34-2.80, p = 0.01 and ß = 1.57, 95% CI = 0.06-3.08, p = 0.04 respectively). CONCLUSIONS: This study found positive attitudes toward adopting the multi-component CombinADO study interventions among HIV care providers for AYAHIV in Nampula, Mozambique. Our findings suggest that adequate training and human resource availability may be important in promoting the adoption of novel multi-component interventions in healthcare services by influencing healthcare provider attitudes.

Intervention Fidelity to VITAL Start (Video Intervention to Inspire Treatment Adherence for Life) in a Randomized Controlled Trial Among Women Living With HIV in Malawi.

BACKGROUND: Intervention effectiveness in a randomized controlled trial is attributed to intervention fidelity. Measuring fidelity has increasing significance to intervention research and validity. The purpose of this article is to describe a systematic assessment of intervention fidelity for VITAL Start (Video intervention to Inspire Treatment Adherence for Life)-a 27-minute video-based intervention designed to improve antiretroviral therapy adherence among pregnant and breastfeeding women. METHOD: Research Assistants (RAs) delivered VITAL Start to participants after enrolment. The VITAL Start intervention had three components: a pre-video orientation, video viewing, and post-video counseling. Fidelity assessments using checklists comprised self (RA assessment) and observer (Research Officers, also known as ROs) assessment. Four fidelity domains (adherence, dose, quality of delivery, and participant responsiveness) were evaluated. Score scale ranges were 0 to 29 adherence, 0 to 3 dose, 0 to 48 quality of delivery and 0 to 8 participant responsiveness. Fidelity scores were calculated. Descriptive statistics summarizing the scores were performed. RESULTS: In total, eight RAs delivered 379 VITAL Start sessions to 379 participants. Four ROs observed and assessed 43 (11%) intervention sessions. The mean scores were 28 (SD = 1.3) for adherence, 3 (SD = 0) for dose, 40 (SD = 8.6) for quality of delivery, and 10.4 (SD = 1.3) for participant responsiveness. CONCLUSION: Overall, the RAs successfully delivered the VITAL Start intervention with high fidelity. Intervention fidelity monitoring should be an important element of randomized control trial design of specific interventions to ensure having reliable study results.

Lower Insulin Sensitivity in Newborns With In Utero HIV and Antiretroviral Exposure Who Are Uninfected in Botswana.

BACKGROUND: Few data exist on early-life metabolic perturbations in newborns with perinatal HIV and antiretroviral (ARV) exposure but uninfected (HEU) compared to those perinatally HIV unexposed and uninfected (HUU). METHODS: We enrolled pregnant persons with HIV (PWH) receiving tenofovir (TDF)/emtricitabine or lamivudine (XTC) plus dolutegravir (DTG) or efavirenz (EFV), and pregnant individuals without HIV, as well as their liveborn infants. Newborns were randomized to receive either zidovudine (AZT) or nevirapine (NVP) postnatal prophylaxis. Preprandial homeostasis model assessment for insulin resistance (HOMA-IR) was assessed at birth and 1 month. Linear mixed models were fit to assess the association between in utero HIV/ARV exposure and average HOMA-IR from birth to 1 month, adjusting for confounders. RESULTS: Of 450 newborns, 306 were HEU. HOMA-IR was higher in newborns HEU versus HUU after adjusting for confounders (mean difference of 0.068 in log HOMA-IR, P = .037). Among newborns HEU, HOMA-IR was not significantly different between TDF/XTC/DTG versus TDF/XTC/EFV in utero ARV exposure and between AZT versus NVP newborn postnatal prophylaxis arms. CONCLUSIONS: Newborns HEU versus HUU had lower insulin sensitivity at birth and at 1 month of life, raising potential concern for obesity and other metabolic perturbations later in life for newborns HEU.

Potential of Long-Acting Products to Transform the Treatment and Prevention of Human Immunodeficiency Virus (HIV) in Infants, Children, and Adolescents.

Long-acting antiretroviral products have the potential to transform human immunodeficiency virus (HIV) prevention and treatment approaches in pediatric populations. Broadly neutralizing antibodies and/or long-acting antiretroviral formulations by injection could dramatically improve provision of HIV prophylaxis and/or early treatment to newborns and infants at risk of HIV infection. Challenges in daily oral antiretroviral administration to toddlers and school age children living with HIV may be relieved by use of long-acting formulations, but the pharmacokinetics and safety of these products in children must be studied before they can enter routine clinical use. Although some initial studies of broadly neutralizing antibodies and injectable long-acting agents in infants and young children are underway, more studies of these and other long-acting products are needed. For many adolescents, compliance with daily medication administration is especially challenging. Long-acting products hold particular promise for adolescents living with HIV as well as those at high risk of HIV acquisition, and adolescents can usually be included in the drug development pipeline simultaneously with adults. Long-acting products have the potential to provide alternatives to lifelong daily oral drug administration across the pediatric age spectrum, leading to more effective prevention and treatment of HIV infection in infants, children, and adolescents.

Standardized Definitions of In Utero Human Immunodeficiency Virus and Antiretroviral Drug Exposure Among Children.

In countries with high human immunodeficiency virus (HIV) prevalence, up to 30% of pregnant women are living with HIV, with fetal exposure to both HIV and antiretroviral therapy during pregnancy. In addition, pregnant women without HIV but at high risk of HIV acquisition are increasingly receiving HIV preexposure antiretroviral prophylaxis (PrEP). Investments are being made to establish and follow cohorts of children to evaluate the long-term effects of in utero HIV and antiretroviral exposure. Agreement on a key set of definitions for relevant exposures and outcomes is important both for interpreting individual study results and for comparisons across cohorts. Harmonized definitions of in utero HIV and antiretroviral drug (maternal treatment or PrEP) exposure will also facilitate improved classification of these exposures in future observational studies and clinical trials. The proposed definitions offer a uniform approach to facilitate the consistent description and estimation of effects of HIV and antiretroviral exposures on key child health outcomes.

Predictors of Cell-Associated Human Immunodeficiency Virus (HIV)-1 DNA Over 1 Year in Very Early Treated Infants.

BACKGROUND: Younger age of antiretroviral therapy (ART) initiation is associated with smaller viral reservoirs in perinatally acquired HIV-1 infection, but there is wide variability among early-treated infants. Predictors of this variability are not fully described. METHODS: Sixty-three neonates diagnosed with HIV-1 <48 hours after birth in Johannesburg, South Africa, were started on ART as soon as possible. Fifty-nine (94%) infants received nevirapine prophylaxis from birth until ART start. Viably preserved peripheral blood mononuclear cells (PBMCs) collected at regular intervals to 48 weeks, and from mothers at enrollment, were tested using integrase-targeted, semi-nested, real-time quantitative hydrolysis probe (TaqMan) PCR assays to quantify total HIV-1 subtype C viral DNA (vDNA). Predictors were investigated using generalized estimating equation regression. RESULTS: Thirty-one (49.2%) infants initiated ART <48 hours, 24 (38.1%) <14 days, and 8 (12.7%) >14 days of birth. Three-quarters were infected despite maternal antenatal ART (however, only 9.5% of women had undetectable viral load closest to delivery) and 86% were breastfed. Higher infant CD4+ T-cell percentage and viral load <100 000 copies/mL pre-ART were associated with lower vDNA in the first 48 weeks after ART start. No antenatal maternal ART and breastfeeding were also associated with lower vDNA. Older age at ART initiation had a discernible negative impact when initiated >14 days. CONCLUSIONS: Among very early treated infants, higher CD4+ T-cell percentage and viral load <100 000 copies/mL pre-ART, infection occurring in the absence of maternal antenatal ART, and breastfeeding were associated with lower levels of HIV-1 DNA in the first 48 weeks of treatment.

Dolutegravir plus Two Different Prodrugs of Tenofovir to Treat HIV.

BACKGROUND: Two drugs under consideration for inclusion in antiretroviral therapy (ART) regimens for human immunodeficiency virus (HIV) infection are dolutegravir (DTG) and tenofovir alafenamide fumarate (TAF). There are limited data on their use in low- and middle-income countries. METHODS: We conducted a 96-week, phase 3, investigator-led, open-label, randomized trial in South Africa, in which we compared a triple-therapy combination of emtricitabine (FTC) and DTG plus either of two tenofovir prodrugs - TAF (TAF-based group) or tenofovir disoproxil fumarate (TDF) (TDF-based group) - against the local standard-of-care regimen of TDF-FTC-efavirenz (standard-care group). Inclusion criteria included an age of 12 years or older, no receipt of ART in the previous 6 months, a creatinine clearance of more than 60 ml per minute (>80 ml per minute in patients younger than 19 years of age), and an HIV type 1 (HIV-1) RNA level of 500 copies or more per milliliter. The primary end point was the percentage of patients with a 48-week HIV-1 RNA level of less than 50 copies per milliliter (as determined with the Snapshot algorithm from the Food and Drug Administration; noninferiority margin, -10 percentage points). We report the primary (48-week) efficacy and safety data. RESULTS: A total of 1053 patients underwent randomization from February 2017 through May 2018. More than 99% of the patients were black, and 59% were female. The mean age was 32 years, and the mean CD4 count was 337 cells per cubic millimeter. At week 48, the percentage of patients with an HIV-1 RNA level of less than 50 copies per milliliter was 84% in the TAF-based group, 85% in the TDF-based group, and 79% in the standard-care group, findings that indicate that the DTG-containing regimens were noninferior to the standard-care regimen. The number of patients who discontinued the trial regimen was higher in the standard-care group than in the other two groups. In the per-protocol population, the standard-care regimen had equivalent potency to the other two regimens. The TAF-based regimen had less effect on bone density and renal function than the other regimens. Weight increase (both lean and fat mass) was greatest in the TAF-based group and among female patients (mean increase, 6.4 kg in the TAF-based group, 3.2 kg in the TDF-based group, and 1.7 kg in the standard-care group). No resistance to integrase inhibitors was identified in patients receiving the DTG-containing regimens. CONCLUSIONS: Treatment with DTG combined with either of two tenofovir prodrugs (TAF and TDF) showed noninferior efficacy to treatment with the standard-care regimen. There was significantly more weight gain with the DTG-containing regimens, especially in combination with TAF, than with the standard-care regimen. (ADVANCE ClinicalTrials.gov number, NCT03122262.).

Distinct cord blood C-peptide, adipokine, and lipidomic signatures by in utero HIV exposure.

BACKGROUND: Early-life metabolic derangements in HIV-exposed uninfected (HEU) infants have been reported. METHODS: Pregnant women with HIV and HIV-uninfected pregnant women were enrolled with their newborns in a US cohort from 2011 to 2015. We measured cord insulin, C-peptide, and metabolic cytokines of HEU and HIV-unexposed uninfected (HUU) newborns using ELISA and metabolites, lipid subspecies, and eicosanoids via liquid chromatography/mass spectrometry. Linear regression was employed to assess the association of intrauterine HIV/ART with insulin and C-peptide. Graphical lasso regression was used to identify differences between metabolite/lipid subspecies networks associated with C-peptide. RESULTS: Of 118 infants, 56 were HEU, ART exposed. In adjusted analyses, mean cord insulin (ß = 0.295, p = 0.03) and C-peptide (ß = 0.522, p < 0.01) were significantly higher in HEU vs. HUU newborns. HEU neonates exhibited primarily positive associations between complex lipids and C-peptide, indicative of fuel storage, and augmented associations between cord eicosanoids and cytokines. HUU neonates exhibited negative associations with lipids and C-peptide indicative of increased fuel utilization. CONCLUSION: Higher cord insulin and C-peptide in HEU vs. HUU newborns as well as differences in cord metabolites, metabolic-related cytokines, and eicosanoids may reflect a propensity for fuel storage and an inflammatory milieu suggestive of fetal metabolic changes associated with in utero HIV/ART exposure. IMPACT: There is a paucity of studies assessing cord blood and neonatal metabolic health in HIV-exposed uninfected (HEU) newborns, an increasing population worldwide. Compared to HIV-unexposed uninfected (HUU) newborns, HEU newborns exhibit alterations in fuel homeostasis and an inflammatory milieu associated with in utero HIV/antiretroviral therapy (ART) exposure. The long-term implications of these neonatal findings are as yet unknown, but merit continued evaluation as this important and growing population ages into adulthood.

Relationship between pre-pregnancy maternal body mass index and infant weight trajectories in HIV-exposed and HIV-unexposed infants.

BACKGROUND: Maternal HIV and antiretroviral therapy (ART) exposure in utero may influence infant weight, but the contribution of maternal y body mass index (BMI) to early life overweight and obesity is not clear. OBJECTIVE: To estimate associations between maternal BMI at entry to antenatal care (ANC) and infant weight through approximately 1 year of age and to evaluate whether associations were modified by maternal HIV status, maternal HIV and viral load, breastfeeding intensity through 6 months or timing of entry into ANC. METHODS: We followed HIV-uninfected and -infected pregnant women initiating efavirenz-based ART from first antenatal visit through 12 months postpartum. Infant weight was assessed via World Health Organization BMI and weight-for-length z-scores (WLZ) at 6 weeks, 3, 6, 9 and 12 months. We used multivariable linear mixed-effects models to estimate associations between maternal BMI and infant z-scores over time. RESULTS: In 861 HIV-uninfected infants (454 HIV-exposed; 407 HIV-unexposed), nearly 20% of infants were overweight or obese by 12 months of age, regardless of HIV exposure status. In multivariable analyses, increasing maternal BMI category was positively associated with higher infant BMIZ and WLZ scores between 6 weeks and 12 months of age and did not differ by HIV exposure status. However, HIV-exposed infants had slightly lower BMIZ and WLZ trajectories through 12 months of age, compared with HIV-unexposed infants across all maternal BMI categories. Differences in BMIZ and WLZ scores by HIV exposure were not explained by timing of entry into ANC or maternal viral load pre-ART initiation, but z-scores were slightly higher for HIV-exposed infants who were predominantly or exclusively versus partially breastfed. CONCLUSIONS: These findings suggest maternal BMI influences early infant weight gain, regardless of infant HIV exposure status. Intervention to reduce maternal BMI may help to address growing concerns about obesity among HIV-uninfected children.
