RESUMO
BACKGROUND: SARS-CoV-2 seropositivity data in women living with HIV (WLHIV), their infants and associated factors in this subpopulation remain limited. We retrospectively measured SARS-CoV-2 seropositivity from 07/2020-11/2021 among WLHIV and their children in the PROMOTE observational cohort in Uganda, Malawi, and Zimbabwe prior to widespread SARS-CoV-2 vaccination in those countries. METHODS: Plasma stored during 3 waves of the COVID-19 pandemic in East/Southern Africa were tested for SARS-CoV-2 specific IgG antibodies (Ab) using serological assays that detect adaptive immune responses to SARS-CoV-2 spike protein. (EUROIMMUN, Mountain Lakes, New Jersey and Roche Diagnostics, Indianapolis, IN). Modified-Poisson regression models were used to calculate prevalence rate ratios (PRR) and 95% confidence intervals (CI) to identify sociodemographic and clinical risk factors. RESULTS: PROMOTE samples from 918 mothers and 1237 children were analysed. Overall, maternal SARS-CoV-2 seropositivity was 60.1% (95% CI: 56.9 -63.3) and 41.5% (95%CI: 38.8 - 44.2) for children. Non-breastfeeding mothers had a 31% higher risk of SARS-CoV-2 seropositivity compared to breastfeeding mothers (aPRR=1.31, 95%CI: 1.08-1.59). WLHIV with undetectable viral load had a 10% increased risk of SARS-CoV-2 seropositivity (aPRR=1.10, 95%CI: 0.89-1.37). Moreover, those who were normotensive had 12% increased risk SARS-CoV-2 seropositivity (aPRR= 1.12, 95% CI: 0.68-1.85) compared to women with hypertension. Children between 2 and 5 years had a 19% reduced risk of SARS-CoV-2 seropositivity (aPRR=0.81, 95%CI: 0.64-1.02) when compared to younger children. Mother/infant SARS-CoV-2 serostatuses were discordant in 346/802 (43.1%) families tested: mothers+/children- in 72.3%; mothers-/children+ in 26.3%; child+/sibling+ concordance was 34.6%. CONCLUSIONS: These SARS-CoV-2 seropositivity data indicate that by late 2021, about 60% of mothers and about 40% of children in a cohort of HIV-affected families in eastern/southern Africa had been infected with SARS-CoV-2. More mothers than their infants tested SARS-CoV-2+, likely due to a greater external exposure for mothers linked to daily routines/employment, and school closures. Breastfeeding was protective for mothers, likely because of higher likelihood of staying home with young children, and thus less exposure. Discordant results between children within the same families underscores the need to further understand transmission dynamics within households.

BACKGROUND: HIV disclosure is vital in HIV management. Community Health Workers (CHW) were reported to support partner disclosure among HIV affected heterosexual partners with disclosure difficulties. However, time to disclosure attributed to use of CHW led disclosure support mechanism was not documented. This study compared the incidence of sexual partner disclosure among adults living with HIV (ALHIV) with CHW support and those without in the greater Luwero region, Uganda. METHODS: We conducted a quasi-experimental study with two arms allocated by geographically determined clusters and adjusted for between-group differences; among ALHIV in the greater Luwero region of Uganda who had never disclosed to their current primary sexual partners. We allocated study clusters to either a CHW-led intervention or control arm. In both arms, we consecutively recruited participants; those in the intervention arm received CHW disclosure support in addition to routine care. The overall follow-up was six months, and the primary outcome was disclosure to the partner. We used survival analysis with proportional hazard ratios to determine the time to partner disclosure in both arms. RESULTS: A total of 245 participants were enrolled, and 230 (93.9%) completed the study; of these, 112 (48.7%) were in the intervention and 118 (51.3%) in the control arm. The mean age was 31 ± 8 years with a range of 18 to 55 years; the majority were females, 176 (76.5%). The cumulative incidence of disclosure was higher in the intervention arm, 8.76 [95% CI: 7.20-10.67] per 1,000 person-days versus 5.15 [95%CI: 4.85-6.48] per 1,000 person-days in the control arm, log-rank test, X2 = 12.93, P < 0.001. Male gender, aHR = 1.82, tertiary education, aHR = 1.51, and relationship duration of > six months, aHR = 1.19 predicted disclosure. Prior disclosure to a relative, aHR = 0.55, and having more than one sexual partner in the past three months, aHR = 0.74, predicted non-disclosure. CONCLUSION: CHW-led support mechanism increased the rate of sexual partner disclosure among ALHIV with disclosure difficulties. Therefore, to achieve the global targets of ending HIV, near location CHW-led disclosure support mechanism may be used to hasten HIV disclosure in rural settings.

BACKGROUND: HIV status disclosure among sexual partners is vital in HIV management. Community health workers (CHW) support HIV disclosure among adults living with HIV (ALHIV) in sexual relationships with disclosure difficulties. However, experiences and challenges of using CHW-led disclosure support mechanism were not documented. This study explored experiences and challenges involved in using CHW-led disclosure support mechanism among ALHIV in heterosexual relationships in the rural Uganda. METHODS: This was a phenomenological qualitative study involving in-depth interviews among CHWs and ALHIV with HIV disclosure difficulties to sexual partners in greater Luwero region, Uganda. We conducted 27 interviews among purposively selected CHWs and participants who had participated in the CHW-led disclosure support mechanism. Interviews were conducted until saturation was reached; and analysis was done using inductive and deductive content analysis in Atlas. RESULTS: All respondents viewed HIV disclosure as an important strategy in HIV management. Provision of adequate counseling and support to those intending to disclose was instrumental for successful disclosure. However, fear of the negative disclosure outcomes was viewed as a barrier to disclosure. The CHWs were viewed as having an added advantage in supporting disclosure as opposed to the routine disclosure counseling. However, HIV disclosure using CHW-led support mechanism would be limited by possible bleach of client's confidentiality. Therefore, respondents thought that appropriate selection of CHWs would improve their trust in the community. Additionally, providing CHWs with adequate training and facilitation during the disclosure support mechanism was viewed to improve their work. CONCLUSION: Community health workers were viewed as being more supportive in HIV disclosure among ALHIV with disclosure difficulties to sexual partners compared to routine facility based disclosure counseling. Therefore, near location CHW-led disclosure mechanism was acceptable and useful in supporting HIV disclosure among HIV-affected sexual partners in rural settings.

BACKGROUND: Viral load (VL) testing is the gold-standard approach for monitoring human immunodeficiency virus (HIV) treatment success and virologic failure, but uptake is suboptimal in resource-limited and rural settings. We conducted a cross-sectional study of risk factors for non-uptake of VL testing in rural Uganda. METHODS: We conducted a cross-sectional analysis of uptake of VL testing among randomly selected people with HIV (PWH) receiving anti-retroviral treatment (ART) for at least 6 months at all eight primary health centers in Gomba district, rural Uganda. Socio-demographic and clinical data were extracted from medical records for the period January to December 2017. VL testing was routinely performed 6 months after ART initiation and 12 months thereafter for PWH stable on ART. We used descriptive statistics and multivariable logistic regression to evaluate factors associated with non-uptake of VL testing (the primary outcome). RESULTS: Of 414 PWH, 60% were female, and the median age was 40 years (interquartile range [IQR] 31-48). Most (62.3%) had been on ART > 2 years, and the median duration of treatment was 34 months (IQR 14-55). Thirty three percent did not receive VL testing: 36% of women and 30% of men. Shorter duration of ART (≤2 years) (adjusted odds ratio [AOR] 2.38; 95% CI:1.37-4.12; p = 0.002), younger age 16-30 years (AOR 2.74; 95% CI:1.44-5.24; p = 0.002) and 31-45 years (AOR 1.92; 95% CI 1.12-3.27; p = 0.017), and receipt of ART at Health Center IV (AOR 2.85; 95% CI: 1.78-4.56; p < 0.001) were significantly associated with non-uptake of VL testing. CONCLUSIONS: One-in-three PWH on ART missed VL testing in rural Uganda. Strategies to improve coverage of VL testing, such as VL focal persons to flag missed tests, patient education and demand creation for VL testing are needed, particularly for recent ART initiates and younger persons on treatment, in order to attain the third Joint United Nations Program on HIV/AIDS (UNAIDS) 95-95-95 target - virologic suppression for 95% of PWH on ART.

BACKGROUND: Lifelong antiretroviral treatment (ART) use is recommended for pregnant and breastfeeding (BF) women living with HIV (WLWH) to prevent perinatal HIV transmission and improve maternal health. We address 2 objectives in this analysis: (1) determine timing and factors associated with BF cessation and (2) assess the impact of BF on health of WLWH on ART. SETTING: This multicountry study included 8 sites in Uganda, Malawi, Zimbabwe, and South Africa. METHODS: This was a prospective study of WLWH on lifelong ART. These women initially participated from 2011 to 2016 in a randomized clinical trial (PROMISE) to prevent perinatal HIV transmission and subsequently reenrolled in an observational study (PROMOTE, 2016-2021) to assess ART adherence, safety, and impact. RESULTS: The PROMOTE cohort included 1987 women on ART. Of them, 752 breastfed and were included in analyses of objective 1; all women were included in analyses of objective 2. The median time to BF cessation varied by country (11.2-19.7 months). Country of residence, age, and health status of women were significantly associated with time to BF cessation (compared with Zimbabwe: Malawi, adjusted hazard ratio [aHR] 0.50, 95% confidence interval [95% CI]: 0.40 to 0.62, P < 0.001; South Africa, aHR 1.49, 95% CI: 1.11 to 2.00, P = 0.008; and Uganda, aHR 1.77, 95% CI: 1.37 to 2.29, P < 0.001). Women who breastfed had lower risk of being "unwell" compared with women who never breastfed (adjusted rate ratio 0.87, 95% CI: 0.81 to 0.95 P = 0.030). CONCLUSION: Women on lifelong ART should be encouraged to continue BF with no concern for their health. Time to BF cessation should be monitored for proper counseling in each country.

INTRODUCTION: Optimal adherence to antiretroviral therapy (ART) is crucial to promoting maternal-infant health. SETTING: Fourteen sites in 7 countries within sub-Saharan Africa and India. METHODS: The multicomponent, open-label strategy PROMISE trial enrolled breastfeeding mother-infant pairs not meeting in-country criteria for maternal ART (mART) initiation in the postpartum component within 5 days of delivery. Randomization was to mART versus infant NVP (iNVP) prophylaxis. Infants in the mART arm also received 6 weeks of iNVP. Self-reported adherence was assessed in a secondary analysis. Time-to-event analyses were performed to explore the association between adherence and maternal viral load (mVL) in the mART arm. RESULTS: Two thousand four hundred thirty-one mother-infant pairs were enrolled between 2011 and 2014; the baseline maternal median CD4 was 686 (IQR 553-869), and the median mVL was 322 copies/mL (IQR 40-1422). Self-reported adherence was lower in the mART arm compared with the iNVP arm (no missed doses within 4 weeks of all study visits: 66% vs 83%; within 2 weeks: 71% vs 85%; P < 0.0001). The iNVP adherence at week 6 was high in both arms: 97% in mART arm; 95% in iNVP arm. Time-to-event analyses showed that adherence to mART was associated with time to first mVL ≥400 copies/mL ( P < 0.0001). Missing 1 full day of doses over 3 days was associated with a 66% risk of mVL ≥1000 copies/mL (HR: 1.66; 95% CI: 1.37, 1.99). CONCLUSIONS: Postpartum women were less adherent to their own ART than mothers providing their infant's nevirapine prophylaxis. The self-reported missed mART doses were associated with high mVL. Strategies to optimize postpartum mART adherence are urgently needed. CLINICAL TRIAL NUMBER: ClinicalTrials.gov: NCT01061151; closed to follow-up.

BACKGROUND: We evaluated the efficacy of a community health worker (CHW)-led intervention in supporting disclosure among adults living with HIV in heterosexual relationships. METHODS: We conducted a quasi-experimental study with 2 arms allocated by geographically determined clusters and adjusted for between-group differences among adults living with HIV in the greater Luwero region of Uganda who had never disclosed their status to their current primary sexual partners. Clusters were allocated to either a CHW-led intervention or a control arm. In both arms, participants were consecutively recruited. As opposed to receiving routine care for the control arm, participants in the intervention arm received additional CHW disclosure support. The overall follow-up was 6 months, and the primary outcome was disclosure to the sexual partner. Data were analyzed using a clustered modified Poisson regression model with robust standard errors to determine independent factors associated with disclosure. RESULTS: Of the 245 participants who enrolled, 230 (93.9%) completed the study, and 112 (48.7%) of those were in the intervention arm. The median age was 30 (interquartile range=25-37) years, the majority were women (76.5%), and most (80%) did not know their partners' HIV status at study entry. At the end of follow-up, the overall disclosure prevalence was 74.4% (95% confidence interval [CI]=68.2, 79.9) and participants in the intervention arm were 51% more likely to disclose compared to those in the control (adjusted relative ratio [aRR]=1.51; 95% CI=1.28, 1.77). Men were 24% (aRR=1.24; 95% CI=1.07, 1.44) more likely to disclose compared to women, and membership in an HIV/AIDS association increased disclosure by 18% (aRR=1.18; 95% CI=1.01, 1.39). CONCLUSION: CHW support improved disclosure among adults living with HIV in heterosexual relationships when compared to routine care. Therefore, CHW-led mechanisms may be utilized in increasing disclosure among adults living with HIV in heterosexual relationships in rural settings.

OBJECTIVE: To compare childhood physical growth among antiretroviral drug and maternal HIV-exposed uninfected (AHEU) compared with HIV-unexposed uninfected (HUU) children. DESIGN: Longitudinal follow-up of PROMISE trial (NCT01061151) AHEU and age-matched and sex-matched HUU children, enrolled (September 2013 to October 2014) in Malawi and Uganda. METHOD: We compared WHO population standardized z-scores [height-for-age (HAZ), weight-for-age (WAZ), weight-for-height (WHZ), head-circumference-for-age (HCAZ) at 12, 24, 36, 48, and 60 months of age]. We evaluated HUU versus AHEU [in-utero combination antiretroviral treatment (cART) versus Zidovudine (ZDV) alone]; stratified by country, using longitudinal linear and generalized linear mixed models. RESULTS: Of 466 Malawian and 477 Ugandan children, median maternal age at enrollment was 24.5âyears (Malawi) and 27.8âyears (Uganda); more than 90% were breastfed through 12âmonths except Uganda AHEU (64.0%). HAZ scores (adjusted for maternal age, breastfed, and socioeconomic status) were lower among AHEU versus HUU children at every time point, significant (Pâ<â0.05) among Ugandan but not Malawian children. Similar patterns were seen for WAZ but not for WHZ or HCAZ scores. High stunting was observed in both countries, significantly higher in Malawi; and higher among AHEU versus HUU children through 48 months of age, significantly (Pâ<â0.05) among Ugandan but not Malawian children. We found no differences in childhood growth trajectories with in-utero exposures to ZDV compared with cART. CONCLUSION: AHEU versus HUU children had lower median LAZ and WAZ scores persisting through 60âmonths of age. However, proportions of children with stunting or underweight decreased after 24âmonths of age.

BACKGROUND: We report the long-term impact of ART in women of reproductive age (15-49 years) in Africa who have been using ART for up to 10 years. We assess outcomes of retention, adherence, maternal health, fertility intentions, and safety. METHODS: This longitudinal, multicountry study (PROMOTE) enrolled women who initiated ART in an earlier perinatal clinical trial, PROMISE. PROMISE occurred from 2011 to 2016 and PROMOTE follow-up started in 2016 and is ongoing. The PROMOTE study was done at eight sites in four countries: Malawi (Blantyre and Lilongwe), South Africa (Durban and Soweto), Uganda (Kampala), and Zimbabwe (Harare, Seke North, and St Mary's). After baseline enrolment, women and their children are followed up every 6 months to collect information on medical history, antiretroviral therapy (ART) use, adherence, and health information, and to do physical examinations and laboratory tests. Obesity was defined as a body-mass index of 30 kg/m2 or more. Data analyses were restricted to summaries of the main long-term outcomes (retention, adherence, maternal health, fertility intentions, and safety). We used descriptive and stratified analyses, and estimated rates using person-years of follow-up and computed probabilities based on Kaplan-Meier methods. FINDINGS: PROMOTE enrolled 1987 mothers and 2522 children. The median follow-up time for mothers was 41·8 (IQR 35·8-42·0) months and for children was 35·7 (23·8-42·0) months. Overall retention rates were 96·5% for mothers and 94·3% for children at 12 months, and, at 42 months, were 88·9% for mothers and 85·4% for children. 1115 (89·1%) of 1252 women had an undetectable viral load at 42 months, which varied by site (81·7-93·8%). Reported maternal health improved over time, with the proportion of women with excellent to very good health increasing from 67·5% at baseline to 87·5% at 42 months, the proportion of unwell participants who visited a health centre declining from 14·7% to 2·8%, and the proportion of those admitted to hospital declining from 1·5% to 1·0%. The desire to have more children was consistently high at some sites. The proportion of women with obesity was high in South Africa and increased over time from 40·2% at baseline to 52·8% at 42 months. The overall pregnancy rate was 17·6 (95% CI 16·5-18·7) per 100 women-years, and mortality rates were 2·4 (1·4-3·9) per 1000 person-years for mothers and 3·4 (2·2-5·10) per 1000 person-years for children (0-9 years). INTERPRETATION: The findings from this multicountry study are reassuring. These findings show that African women can consistently use ART for a long period after initiation, and long-term benefits can be maintained. Services to support maternal HIV care, treatment, and reproductive health should be strengthened. FUNDING: US President's Emergency Plan for AIDS Relief.

BACKGROUND: Timely viral load (VL) testing is critical in the care of pregnant women living with HIV and receiving anti-retroviral therapy (ART). There is paucity of data regarding the Time to First Viral Load (TFVL) testing in resource-limited settings. METHODS: We extracted clinical and VL test data from records of a cohort of ART-naïve pregnant women living with HIV who initiated Option B + and were retained in care between 01 Jan 2015 and 31 Dec 2015. The data were verified against laboratory VL registers. TFVL (in months) was calculated based on the time difference between the date of ART initiation and FVL test. Descriptive and Cox regression analyses of data up to 30 Sep 2017 (33 months later) were done. RESULTS: Of the 622 records retrieved, 424 women were retained in care. Of 424 women retained in care, 182/424 (43%) had at least one VL result post ART initiation while 242/424 (57%) had no VL performed. Only 30/182 (16.5%) had a second VL. At six, nine, and twelve months, only 8/424 (1.9%), 47/424 (11.1%), and 94/424 (22.2%) had VL testing performed respectively post ART initiation. The median TFVL testing was 12.7 months (95 CI 11.6-13.7) post ART initiation. Across the five clinics, patient factors (age, gravidity, gestational age, marital status, and adherence at 12 months) were not significant predictors. CONCLUSION: A dismal 1.9% rate of achieving WHO-recommended TFVL testing and a median TFVL testing of twelve months post ART initiation were observed. The non-association of patient factors to these observations may suggest a serious need to review health system factors likely associated with these observations and their effective interventions.

ABSTRACT: IMPAACT PROMISE 1077BF/FF was a sequentially randomized study of pregnant and postpartum women living with HIV to investigate the efficacy and safety of antiretroviral therapy (ART). This Maternal Health Component investigated efficacy for the risk of developing AIDS or death; and safety among women randomized to continue ART (CTART: N = 289) or discontinue ART (N = 268) after cessation of breastfeeding or after confirmation of infant infection. No AIDS-defining illnesses were reported during follow-up in either arm. Adverse events of grade 3 or higher were more frequent in the CTART arm [hazard ratio = 1.78, 95% confidence interval: (1.05 to 3.02), P-value = 0.03]. The difference in adverse events in the 2 groups was mostly driven by moderate weight loss for women on the CTART arm.

BACKGROUND: Given well documented challenges faced by pregnant women living with HIV taking lifetime ART, it is critical to understand the impact of short-term ART exposure followed by treatment interruption on maternal health outcomes. METHODS: HIV+ breastfeeding (BF) and Formula Feeding (FF) women with CD4 counts > 350 cells/mm3, enrolled in the 1077BF/1077FF PROMISE trial were followed to assess the effect of ART during pregnancy and breastfeeding respectively. The first analysis compared ART use limited to the antepartum period (AP-only) relative to women randomized to Zidovudine. The second analysis included women with no pregnancy combination ART exposure; and compared women randomized to either ART or no ART during postpartum (PP-only). Both analyses included follow-up time beyond breastfeeding period. The primary outcome was progression to AIDS and/or death. Secondary outcomes included adverse events and HIV-related events. RESULTS: 3490 and 1137 HIV+ women were enrolled from 14 sites in Africa and India from April 2011 through September 2014 in cohort AP-only and PP-only, respectively. Most were Black African (96%); median age was 27 years; 97% were WHO Clinical Stage I; and most had a screening CD4 count ≥500 cells/mm3 (78%). The rate of progression to AIDS and/or death was similar and low across all comparison arms (AP comparison, HR = 1.14, 95%CI (0.44, 2.96), p-value = 0.79). In the PP-only cohort, the rate of WHO stage 2-3 events was lower for women randomized to ART(HR = 0.65, 95% CI 0.42, 1.01, p-value = 0.05). CONCLUSION: The incidence of AIDS and/or death was low in pregnant/postpartum HIV+ women with highCD4 cell counts for all comparison arms. This provides some reassurance that there were limited consequences for short term ART interruption in this group of asymptomatic HIV+ women during up to 4 years of follow up; and underscores that even short term ART exposure postpartum may reduce the risk of WHO grade 2-3 disease progression.

BACKGROUND: Despite recent efforts to scale-up lifelong combination antiretroviral therapy (cART) in sub-Saharan Africa, high rates of unsuppressed viremia persist among cART users, and many countries in the region fall short of the UNAIDS 2020 target to have 90% virally suppressed. We sought to determine the factors associated with unsuppressed viremia (defined for the purpose of this study as >200 copies/ml) among sub-Saharan African women on lifelong cART. METHODS: This cross-sectional analysis was based on baseline data of the PROMOTE longitudinal cohort study at 8 sites in Uganda, Malawi, Zimbabwe and South Africa. The study enrolled 1987 women living with HIV who initiated lifelong cART at least 1-5 years ago. Socio-demographic, clinical, and cART adherence data were collected. We used multivariable Poisson regression with robust variance to identify factors associated with unsuppressed viremia. RESULTS: At enrolment, 1947/1987 (98%) women reported taking cART. Of these, HIV-1 remained detectable in 293/1934 (15%), while 216/1934 (11.2%) were considered unsuppressed (>200 copies/ml). The following factors were associated with an increased risk of unsuppressed viremia: not having household electricity (adjusted prevalence risk ratio (aPRR) 1.74, 95% confidence interval (CI) 1.28-2.36, p<0.001); not being married (aPRR 1.32, 95% CI 0.99-1.78, p = 0.061), self-reported missed cART doses (aPRR 1.63, 95% CI 1.24-2.13, p<0.001); recent hospitalization (aPRR 2.48, 95% CI 1.28-4.80, p = 0.007) and experiencing abnormal vaginal discharge in the last three months (aPRR 1.88; 95% CI 1.16-3.04, p = 0.010). Longer time on cART (aPRR 0.75, 95% CI 0.64-0.88, p<0.001) and being older (aPRR 0.77, 95% CI 0.76-0.88, p<0.001) were associated with reduced risk of unsuppressed viremia. CONCLUSION: Socioeconomic barriers such as poverty, and individual barriers like not being married, young age, and self-reported missed doses are key predictors of unsuppressed viremia. Targeted interventions are needed to improve cART adherence among women living with HIV with this risk factor profile.
