ABSTRACT

In IMPAACT 2010/VESTED, pregnant women were randomized to initiate dolutegravir (DTG)+emtricitabine (FTC)/tenofovir alafenamide (TAF), DTG+FTC/tenofovir disoproxil fumarate (TDF), or efavirenz (EFV)/FTC/TDF. We assessed red blood cell folate concentrations (RBC-folate) at maternal study entry and delivery, and infant birth. RBC-folate outcomes were: 1) maternal change entry to delivery (trajectory), 2) infant, 3) ratio of infant-to-maternal delivery. Generalized estimating equation models for each log(folate) outcome were fit to estimate adjusted geometric mean ratio (Adj-GMR)/GMR trajectories (Adj-GMRT) of each arm comparison in 340 mothers and 310 infants. Overall, 90% of mothers received folic acid supplements and 78% lived in Africa. At entry, median maternal age was 25 years, gestational age was 22 weeks, CD4 count was 482 cells/mm3 and log10HIV RNA was 3 copies/mL. Entry RBC-folate was similar across arms. Adj-GMRT of maternal folate was 3% higher in the DTG+FTC/TAF versus EFV/FTC/TDF arm (1.03, 95%CI 1.00, 1.06). The DTG+FTC/TAF arm had an 8% lower infant-maternal folate ratio (0.92, 95%CI 0.78, 1.09) versus EFV/FTC/TDF. Results are consistent with no clinically meaningful differences between arms for all RBC-folate outcomes and they suggest that cellular uptake of folate and folate transport to the infant do not differ in pregnant women starting DTG- vs. EFV-based ART.

ABSTRACT

OBJECTIVE: Tenofovir alafenamide (TAF)-based antiretroviral therapy (ART) regimens have been associated with adverse changes in lipid and glucose profiles compared with tenofovir disoproxil fumarate (TDF)-based ART, but data in pregnancy is limited. We evaluated metabolic markers in pregnant women with HIV after starting TAF- vs TDF-based ART. METHODS: We analyzed data within the IMPAACT 2010/VESTED trial, which demonstrated better pregnancy outcomes in pregnant women randomized to initiate TAF/Emtricitabine/Dolutegravir (TAF/FTC+DTG; n=217) or TDF/FTC+DTG (n=215). We measured non-fasting plasma concentrations of glucose, total-cholesterol, low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), lipoprotein (a), and triglycerides from samples collected eight weeks after enrollment. We employed linear regression models to estimate by-arm mean differences. RESULTS: 219 participants enrolled in the DTG arms in Zimbabwe and Uganda: 109 in the TAF/FTC+DTG and 110 in the TDF/FTC+DTG arms. At study entry, mean gestational age was 22.6 weeks, median HIV-1 RNA was 711 copies/mL, and mean age was 25.8 years. By eight weeks, mean total cholesterol was 12 mg/dL higher in women randomized to TAF/FTC+DTG versus TDF/FTC+DTG (95% CI 3.8, 21.1). Pregnant women in the TAF/FTC+DTG arm had higher mean LDL-C (7.1 mg/dL, 95% CI 0.2, 14.0), triglycerides (12.3 mg/dL, 95% CI 1.8, 22.7), lipoprotein (a) (7.3 mg/dL, 95% CI 1.1, 13.6), and lower mean HDL-C (2.8 mg/dL, 95% CI 0.1, 5.6) compared to the TDF/FTC+DTG arm. CONCLUSION: Pregnant women randomized to start TAF/FTC+DTG had higher lipids than those randomized to TDF/FTC+DTG within eight weeks of ART initiation. However, lipid levels were within normal reference ranges.

ABSTRACT

BACKGROUND: We evaluated associations between antepartum weight change and adverse pregnancy outcomes and between antiretroviral therapy (ART) regimens and week 50 postpartum body mass index in IMPAACT 2010. METHODS: Women with human immunodeficiency virus (HIV)-1 in 9 countries were randomized 1:1:1 at 14-28 weeks' gestational age (GA) to start dolutegravir (DTG) + emtricitabine (FTC)/tenofovir alafenamide fumarate (TAF) versus DTG + FTC/tenofovir disoproxil fumarate (TDF) versus efavirenz (EFV)/FTC/TDF. Insufficient antepartum weight gain was defined using Institute of Medicine guidelines. Cox-proportional hazards regression models were used to evaluate the association between antepartum weight change and adverse pregnancy outcomes: stillbirth (≥20 weeks' GA), preterm delivery (<37 weeks' GA), small size for GA (<10th percentile), and a composite of these endpoints. RESULTS: A total of 643 participants were randomized: 217 to the DTG + FTC/TAF, 215 to the DTG + FTC/TDF, and 211 to the EFV/FTC/TDF arm. Baseline medians were as follows: GA, 21.9 weeks; HIV RNA, 903 copies/mL; and CD4 cell count, 466/µL. Insufficient weight gain was least frequent with DTG + FTC/TAF (15.0%) versus DTG + FTC/TDF (23.6%) and EFV/FTC/TDF (30.4%). Women in the DTG + FTC/TAF arm had the lowest rate of composite adverse pregnancy outcome. Low antepartum weight gain was associated with higher hazard of composite adverse pregnancy outcome (hazard ratio, 1.44 [95% confidence interval, 1.04-2.00]) and small size for GA (1.48 [.99-2.22]). More women in the DTG + FTC/TAF arm had a body mass index ≥25 (calculated as weight in kilograms divided by height in meters squared) at 50 weeks postpartum (54.7%) versus the DTG + FTC/TDF (45.2%) and EFV/FTC/TDF (34.2%) arms. CONCLUSIONS: Antepartum weight gain on DTG regimens was protective against adverse pregnancy outcomes typically associated with insufficient weight gain, supportive of guidelines recommending DTG-based ART for women starting ART during pregnancy. Interventions to mitigate postpartum weight gain are needed.

ABSTRACT

BACKGROUND: Incident HIV during the perinatal period significantly impedes elimination of Mother-to-Child HIV Transmission (eMTCT) efforts. Pre-Exposure Prophylaxis (PrEP) effectively reduces HIV acquisition, and new agents like injectable Cabotegravir (CAB-LA) offer potential advantages for pregnant and breastfeeding women. The Pregnancy, Infant, and Maternal health Outcomes (PrIMO) study will compare rates of composite adverse pregnancy outcomes, and infant adverse events, growth and neurodevelopment between mother-infant dyads receiving CAB-LA and those receiving oral PrEP in Malawi. METHODS: PrIMO is an observational cohort study involving: (1) the development of a PrEP Pregnancy Registry for longitudinal surveillance of pregnant women on PrEP in Malawi; and (2) the enrolment of a prospective safety cohort of 621 pregnant women initiating oral PrEP or CAB-LA and their subsequent infants. The registry will include all women continuing or initiating PrEP during pregnancy across targeted sites in Lilongwe and Blantyre districts. The safety cohort will enrol a subset of those women and their infants from Bwaila District Hospital in Lilongwe, Malawi. We hypothesize that CAB-LA's safety will be comparable to daily oral PrEP regarding adverse pregnancy outcomes, maternal/infant adverse events, and infant development. Participants in the cohort will choose either oral PrEP or CAB-LA and will be followed until 52 weeks post-delivery. Safety data will be collected from all mother-infant pairs and qualitative interviews will be conducted with a subset of purposively selected women (n = 50) to assess the acceptability of each PrEP modality. DISCUSSION: The PrIMO study will provide critical data on the safety of CAB-LA in pregnant and breastfeeding women and their infants. Results will guide clinical recommendations as the Malawi Ministry of Health prepares for the rollout of CAB-LA to this population. Evaluation of Registry implementation will inform its expansion to a nationwide safety monitoring system for PrEP use during pregnancy, with implications for similar systems in the region. TRIAL REGISTRATION NUMBER: NCT06158126. The study was prospectively registered (5 December 2023) in ClinicalTrials.gov.

ABSTRACT

Research suggests that women's experience of intimate partner violence (IPV) is associated with poor engagement in HIV care and treatment. However, most studies have been cross-sectional and conducted in North America. We examined the association between physical IPV and HIV care outcomes in a prospective cohort study of women living with HIV (WLHIV) in Malawi, South Africa, Uganda, and Zimbabwe. At enrollment, 15% of the 351 participants self-reported physical IPV. IPV experience was not associated with time to first engagement in HIV care or the proportion virally suppressed after 6 months on ART. Women reporting physical IPV were less likely to initiate ART within 6 months of becoming eligible (adjusted RR 0.74, 95% CI 0.53-1.03). IPV screening is critical to identify survivors and link them to appropriate services. However, addressing IPV may not increase engagement in HIV care or viral load suppression among WLHIV in sub-Saharan Africa.

ABSTRACT

MTN-025/HOPE was an open-label trial of the dapivirine vaginal ring conducted in four African countries between 2016 and 2018. Women were first offered one ring monthly (at baseline, months 1 and 2), thereafter, transitioned to a more applicable real-world dispensation schedule, - 3 rings quarterly (at months 3, 6 and 9). Logistic regression analysis was used to assess correlates of ring acceptance at baseline and through follow-up. A total of 1456 women (median age 31 years) enrolled, 1342 (92.2%) accepted the ring at baseline and 1163 (79.9%) accepted the ring(s) at all visits. Changing ring dispensation from a monthly to a quarterly schedule had no negative effect on acceptance. Having a primary partner and him knowing about the ring being offered in HOPE, use of long-acting contraception (implants, injections, IUDs) or sterilization were associated with ring acceptance, along with prior strong intention to use the ring in the future. Efforts should consider these factors when rolling out the ring for HIV prevention.

ABSTRACT

BACKGROUND: Cytology-based cervical cancer screening followed by confirmation and treatment of biopsy-proven high-grade squamous intraepithelial lesions (bHSIL) is difficult to implement in resource-constrained settings. We hypothesized that high-risk human papillomavirus (hrHPV) testing followed by immediate cryotherapy of women with hrHPV (HPV screen-and-treat) may improve outcomes. METHODS: Randomized, open-label, phase 2, multinational clinical trial enrolling women with human immunodeficiency virus (HIV) age 18 or older with cervical hrHPV and having no cervical lesions or lesions appropriate for cryotherapy. Women were randomized to immediate cryotherapy (Arm A) or cytology-based screening (Arm B). For Arm A, cervical biopsies were obtained followed by cervical cryotherapy, and in Arm B, women with abnormal cytology underwent colposcopy followed by loop electroexcision procedure (LEEP) if bHSIL was detected. Women were followed through 30 months. The primary outcome was time to bHSIL detected from Month 6 through study completion. RESULTS: In total, 288 women (145 in Arm A, 143 in Arm B) were randomized: median age 35 years, 84% on antiretroviral therapy, median CD4 501 cells/mm3. In Arm A, 39 (27%) of women had bHSIL at entry, and in Arm B, 88 (62%) had abnormal cytology, 22 (15%) were diagnosed with bHSIL, 12 (8%) underwent LEEP. In follow-up, 30 (21%) and 31 (22%) developed bHSIL; time to bHSIL was similar between arms (P=.94). The prevalence of hrHPV at Month 6 was similar between arms (61% and 70%, P=.13). CONCLUSIONS: HPV test-and-treat was not associated with improved bHSIL outcomes as compared to cytology-based screening. More effective treatment options are required to improve outcomes from screen-and-treat programs. CLINICAL TRIALS REGISTRATION: NCT01315363.

ABSTRACT

BACKGROUND: Antiretroviral therapy (ART) during pregnancy is important for both maternal health and prevention of perinatal HIV-1 transmission; however adequate data on the safety and efficacy of different ART regimens that are likely to be used by pregnant women are scarce. In this trial we compared the safety and efficacy of three antiretroviral regimens started in pregnancy: dolutegravir, emtricitabine, and tenofovir alafenamide fumarate; dolutegravir, emtricitabine, and tenofovir disoproxil fumarate; and efavirenz, emtricitabine, and tenofovir disoproxil fumarate. METHODS: This multicentre, open-label, randomised controlled, phase 3 trial was done at 22 clinical research sites in nine countries (Botswana, Brazil, India, South Africa, Tanzania, Thailand, Uganda, the USA, and Zimbabwe). Pregnant women (aged ≥18 years) with confirmed HIV-1 infection and at 14-28 weeks' gestation were eligible. Women who had previously taken antiretrovirals in the past were excluded (up to 14 days of ART during the current pregnancy was permitted), as were women known to be pregnant with multiple fetuses, or those with known fetal anomaly or a history of psychiatric illness. Participants were randomly assigned (1:1:1) using a central computerised randomisation system. Randomisation was done using permuted blocks (size six) stratified by gestational age (14-18, 19-23, and 24-28 weeks' gestation) and country. Participants were randomly assigned to receive either once-daily oral dolutegravir 50 mg, and once-daily oral fixed-dose combination emtricitabine 200 mg and tenofovir alafenamide fumarate 25 mg; once-daily oral dolutegravir 50 mg, and once-daily oral fixed-dose combination emtricitabine 200 mg and tenofovir disoproxil fumarate 300 mg; or once-daily oral fixed-dose combination of efavirenz 600 mg, emtricitabine 200 mg, and tenofovir disoproxil fumarate 300 mg. The primary efficacy outcome was the proportion of participants with viral suppression, defined as an HIV-1 RNA concentration of less than 200 copies per mL, at or within 14 days of delivery, assessed in all participants with an HIV-1 RNA result available from the delivery visit, with a prespecified non-inferiority margin of -10% in the combined dolutegravir-containing groups versus the efavirenz-containing group (superiority was tested in a pre-planned secondary analysis). Primary safety outcomes, compared pairwise among treatment groups, were the occurrence of a composite adverse pregnancy outcome (ie, either preterm delivery, the infant being born small for gestational age, stillbirth, or spontaneous abortion) in all participants with a pregnancy outcome, and the occurrence of grade 3 or higher maternal and infant adverse events in all randomised participants. This trial was registered with ClinicalTrials.gov, NCT03048422. FINDINGS: Between Jan 19, 2018, and Feb 8, 2019, we enrolled and randomly assigned 643 pregnant women: 217 to the dolutegravir, emtricitabine, and tenofovir alafenamide fumarate group, 215 to the dolutegravir, emtricitabine, and tenofovir disoproxil fumarate group, and 211 to the efavirenz, emtricitabine, and tenofovir disoproxil fumarate group. At enrolment, median gestational age was 21·9 weeks (IQR 18·3-25·3), the median HIV-1 RNA concentration among participants was 902·5 copies per mL (152·0-5182·5; 181 [28%] of 643 participants had HIV-1 RNA concentrations of <200 copies per mL), and the median CD4 count was 466 cells per µL (308-624). HIV-1 RNA concentrations at delivery were available for 605 (94%) participants. Of these, 395 (98%) of 405 participants in the combined dolutegravir-containing groups had viral suppression at delivery compared with 182 (91%) of 200 participants in the efavirenz, emtricitabine, and tenofovir disoproxil fumarate group (estimated difference 6·5% [95% CI 2·0 to 10·7], p=0·0052; excluding the non-inferiority margin of -10%). Significantly fewer participants in the dolutegravir, emtricitabine, and tenofovir alafenamide fumarate group (52 [24%] of 216) had a composite adverse pregnancy outcome than those in the dolutegravir, emtricitabine, and tenofovir disoproxil fumarate group (70 [33%] of 213; estimated difference -8·8% [95% CI -17·3 to -0·3], p=0·043) or the efavirenz, emtricitabine, and tenofovir disoproxil fumarate group (69 [33%] of 211; -8·6% [-17·1 to -0·1], p=0·047). The proportion of participants or infants with grade 3 or higher adverse events did not differ among the three groups. The proportion of participants who had a preterm delivery was significantly lower in the dolutegravir, emtricitabine, and tenofovir alafenamide fumarate group (12 [6%] of 208) than in the efavirenz, emtricitabine, and tenofovir disoproxil fumarate group (25 [12%] of 207; -6·3% [-11·8 to -0·9], p=0·023). Neonatal mortality was significantly higher in the efavirenz, emtricitabine, and tenofovir disoproxil fumarate group (ten [5%] of 207 infants) than in the dolutegravir, emtricitabine, and tenofovir alafenamide fumarate group (two [1%] of 208; p=0·019) or the dolutegravir, emtricitabine, and tenofovir disoproxil fumarate group (three [2%] of 202; p=0·050). INTERPRETATION: When started in pregnancy, dolutegravir-containing regimens had superior virological efficacy at delivery compared with the efavirenz, emtricitabine, and tenofovir disoproxil fumarate regimen. The dolutegravir, emtricitabine, and tenofovir alafenamide fumarate regimen had the lowest frequency of composite adverse pregnancy outcomes and of neonatal deaths.

ABSTRACT

BACKGROUND: Community health workers (CHWs) are essential field-based personnel and increasingly used to deliver priority interventions to achieve universal health coverage. Existing literature allude to the potential for detrimental effects of multi-tasking CHWs. This study objective was to assess the impact of integrating cervical cancer screening and prevention therapy (CCSPT) with family planning (FP) on time utilization among CHWs. METHODS: A time and motion study was conducted in 7 health facilities in Malawi. Data was collected at baseline between October-July 2019, and 12 months after CCSPT implementation between July and August 2021. CHWs trained to deliver CCSPT were continuously observed in real time while their activities were timed by independent observers. We used paired sample t-test to assess pre-post differences in average hours CHWs spent on the following key activities, before and after CCSPT implementation: clinical and preventive care; administration; FP; and non-work-related tasks. Regression models were used to ascertain impact of CCSPT on average durations CHWs spent on key activities. RESULTS: Thirty-seven (n = 37) CHWs were observed. Their mean age and years of experience were 42 and 17, respectively. Overall, CHWs were observed for 323 hours (inter quartile range: 2.8-5.5). Compared with the period before CCSPT, the proportion of hours CHWs spent on clinical and preventive care, administration and non-work-related activities were reduced by 13.7, 8.7 and 34.6%, respectively. CHWs spent 75% more time on FP services after CCSPT integration relative to the period before CCSPT. The provision of CCSPT resulted in less time that CHWs devoted towards clinical and preventive care but this reduction was not significant. Following CCPST, CHWs spent significantly few hours on non-work-related activities. CONCLUSION: Introduction of CCSPT was not very detrimental to pre-existing community services. CHWs managed their time ensuring additional efforts required for CCSPT were not at the expense of essential activities. The programming and policy implications are that multi-tasking CHWs with CCSPT will not have substantial opportunity costs.

ABSTRACT

BACKGROUND: Globally, the number of infected women of childbearing age living with human immunodeficiency virus (HIV) and conceiving on antiretroviral therapy (ART) is increasing. Evidence of ART safety at conception and during pregnancy and adverse pregnancy outcomes remains conflicting. The Promoting Maternal and Infant Survival Everywhere (PROMISE) 1077 breastfeeding (BF) and formula feeding (FF) international multisite trials provide an opportunity to examine the impact of ART at conception on pregnancy outcomes with subsequent pregnancies. METHODS: The PROMISE 1077BF/1077FF trials were designed to address key questions in the management of HIV-infected women who did not meet clinical guidelines for ART treatment during the time of the trials. After the period of risk of mother-to-child transmission was over, women were randomized to either continue or discontinue ART. We compared subsequent pregnancy outcomes of nonbreastfeeding women randomized to continue ART following delivery, or breastfeeding women randomized to continue ART following breastfeeding cessation who conceived while on ART to women randomized to discontinue ART, who restarted ART after pregnancy was diagnosed. RESULTS: Pregnancy outcomes of 939 subsequent pregnancies of 826 mothers were recorded. The intention-to-treat analyses showed increased incidence of low birth weight (<2500 g) for women who conceived while on ART (relative risk, 2.65 [95% confidence interval {CI}, 1.20-5.81]), and also a higher risk of spontaneous abortion, stillbirth, or neonatal death (hazard ratio, 1.40 [95% CI, .99-1.98]) compared to women who restarted ART after they were found to be pregnant during trial follow-up. CONCLUSIONS: We found an increased risk for adverse pregnancy outcomes in women conceiving on ART, emphasizing the need for improved obstetric and neonatal care for this group.

ABSTRACT

Malawi has the highest invasive cervical cancer (ICC) mortality rate worldwide, and ICC is the leading cause of cancer death among women. In 2004, Malawi adopted visual inspection with acetic acid (VIA) and ablative treatment with cryotherapy. However, screening coverage has remained low (<30%) and few women (<50%) who require ablative treatment receive it. Additional barriers include long distances to health facilities and challenges with maintaining gas supplies. Thermal ablation is a safe and effective alternative to cryotherapy. We assessed the safety and uptake of community-based ICC screening with VIA and same-day treatment using a handheld thermocoagulator (HTU) in rural Malawi. We held educational talks alongside community leaders and conducted VIA screening in nonclinic community settings to nonpregnant women aged 25 to 49 years without history of hysterectomy or genital cancer/precancer. Eligible women received same-day thermal ablation and HIV testing/counseling. We collected cervical biopsies before treatment and followed up women at Weeks 6 and 12, with repeat biopsy at Week 12. Between July and August 2017, 408 (88%) of 463 eligible women underwent VIA. Overall, 7% (n = 30) of women had a positive VIA, of whom 93% (n = 28) underwent same-day thermal ablation. Among the 30 VIA-positive women, 5 had cervical intraepithelial neoplasia (CIN) 1, 4 had CIN 2/3 and 21 had benign histologic findings. Abnormal vaginal discharge (60%) and light vaginal bleeding (52%) were the most reported adverse events. There was high uptake of the community-based ICC screening in the study population and treatment was safe in this setting. Similar strategies that minimize false-positive results are urgently needed in Malawi.

ABSTRACT

BACKGROUND: Malawi has the world's highest cervical cancer incidence and mortality due to high rate of HIV coupled with inadequate screening and treatment services. The country's cervical cancer control program uses visual inspection with acetic acid (VIA) and cryotherapy, but screening is largely limited by poor access to facilities, high cost of cryotherapy gas, and high loss-to-follow-up. To overcome these limitations, we implemented a community-based screen-and-treat pilot program with VIA and thermocoagulation. Through a qualitative study, we explore the experiences of women who underwent this community-based pilot screening program. METHODS: We implemented our pilot program in rural Malawi and conducted an exploratory qualitative sub-study. We conducted in-depth interviews with women who were treated with thermocoagulation during the program. We used semi-structured interviews to explore screen-and-treat experience, acceptability of the program and attitudes towards self-sampling for HPV testing as an alternative screening method. Content analysis was conducted using NVIVO v12. RESULTS: Between July - August 2017, 408 participants eligible for screening underwent VIA screening. Thirty participants had VIA positive results, of whom 28 underwent same day thermocoagulation. We interviewed 17 of the 28 women who received thermocoagulation. Thematic saturation was reached at 17 interviews. All participants reported an overall positive experience with the community-based screen-and-treat program. Common themes were appreciation for bringing screening directly to their villages, surprise at the lack of discomfort, and the benefits of access to same day treatment immediately following abnormal screening. Negative experiences were rare and included discomfort during speculum exam, long duration of screening and challenges with complying with postprocedural abstinence. Most participants felt that utilizing self-collected HPV testing could be acceptable for screening in their community. CONCLUSIONS: Our exploratory qualitative sub-study demonstrated that the community-based screen-and-treat with VIA and thermocoagulation was widely accepted. Participants valued the accessible, timely, and painless thermocoagulation treatment and reported minimal side effects. Future considerations for reaching rural women can include community-based follow-up, cervical cancer education for male partners and self-sampling for HPV testing.

ABSTRACT

Research in rapidly evolving policy contexts can lead to the following ethical challenges for sponsors and researchers: the study's standard of care can become different than what patients outside the study receive, there may be political or other pressure to move ahead with unproven interventions, and new findings or revised policies may decrease the relevance of ongoing studies. These ethical challenges are considerable, but not unprecedented. In this article, we review the case of a multinational, randomized, controlled perinatal HIV prevention trial, the "PROMISE" (Promoting Maternal Infant Survival Everywhere) study. PROMISE compared the relative efficacy and safety of interventions to prevent mother to child transmission of HIV. The sponsor engaged an independent international ethics panel to address controversy about the study's standard of care and relevance as national and international guidelines changed. This ethics panel concluded that continuing the PROMISE trial as designed was ethically permissible because: (1) participants in all arms received interventions that were effective, and there was insufficient evidence about whether one intervention was more effective or safer than the other, and (2) data from PROMISE could be useful for a diverse range of stakeholders. In general, trials designed to inform rapidly evolving policy issues should develop mechanisms to revisit social value while recognizing that the value of research varies for diverse stakeholders with legitimate reasons to weigh evidence differently. We conclude by providing four reasons that trials may depart from the standard of care after a change in policy, while remaining ethically justifiable, and by suggesting how to improve existing trial oversight mechanisms to address evolving social value.

ABSTRACT

Background: Limited information exists about relationship dynamics and their role in HIV acquisition, HIV disclosure, hormonal contraceptive uptake, and condom use among women in Malawi.Methods: Ninety-seven women aged 18-45 years were randomly assigned to initiate the depot medroxyprogesterone acetate injectable or levonorgestrel implant from May 2014 to April 2015 in Lilongwe, Malawi. Women were recruited after randomisation to participate in semi-structured interviews about HIV and family planning using purposive sampling. Interviews were thematically analysed using within and between group comparisons.Results: We conducted individual interviews and/or focus group discussions with 41 women: 30 (73%) women living with HIV and 11 (27%) women not living with HIV. Most women living with HIV who participated in in-depth interviews disclosed their status to their partners, and most partners agreed to get HIV tested only after disclosure. Nearly all women said their partners agreed to use condoms, but few used them consistently. Nearly all women believed their current and former partners had outside partners. Most women living with HIV who participated in in-depth interviews believed their current or other serious partners were the source of their infection. Some women thought their partner's infidelity was due to their partner's disinterest in sex with them during menstrual/ breakthrough bleeding. Some women included their partners in contraceptive decision-making when the partner was supportive.Discussion: Relationship dynamics affected decision-making for contraceptive and condom use, as well as serodisclosure for the women living with HIV in the study. All women reported challenges with consistent condom use with their male partners, although contraceptive use was generally more acceptable. Women included their partners in their decision-making concerning contraceptive use when they were supportive.

ABSTRACT

BACKGROUND: Stillbirth and neonatal mortality are very high in many low-income countries, including Malawi. Use of family planning to encourage birth spacing may optimize outcomes for subsequent pregnancies. However, reproductive desires and influences on birth spacing preferences of women who have experienced a stillbirth or neonatal death in low-resource settings are not well understood. METHODS: We conducted a qualitative study using 20 in-depth interviews and four focus group discussions with women who had experienced a stillborn baby or early neonatal death to explore attitudes surrounding birth spacing and potential interventions to promote family planning in this population. Qualitative data were analyzed for recurrent patterns and themes and central ideas were extracted to identify their core meanings. RESULTS: Forty-six women participated in the study. After experiencing a stillbirth or neonatal death, most women wanted to wait to become pregnant again but women with living children wished to wait for longer periods of time than those with no living children. Most women preferred birth spacing interventions led by clinical providers and inclusion of their spouses. CONCLUSIONS: Many influences on family size and birth spacing were noted in this population, with the most significant influencing factor being the spouse. Interventions to promote birth spacing and improve maternal and neonatal health in this population need to involve male partners and knowledgeable health care providers to be effective.

ABSTRACT

BACKGROUND: About 90% of unintended pregnancies are attributed to non-use of effective contraception-tubal ligation, or reversible effective contraception (REC) including injectables, oral pills, intra-uterine contraceptive device (IUCD), and implant. We assessed the prevalence of unintended pregnancy and factors associated with using RECs, and Long-Acting-Reversible-Contraceptives (LARCs)-implants and IUCDs, among women living with HIV (WLHIV) receiving antiretroviral therapy (ART). METHODS: We conducted cross-sectional analyses of the US-PEPFAR PROMOTE study WLHIV on ART at enrollment. Separate outcome (REC and LARC) modified-Poisson regression models were used to estimate prevalence risk ratio (PRR) and corresponding 95% confidence interval (CI). RESULTS: Of 1,987 enrolled WLHIV, 990 (49.8%) reported their last/current pregnancy was unintended; 1,027/1,254 (81.9%) non-pregnant women with a potential to become pregnant reported current use of effective contraception including 215/1,254 (17.1%) LARC users. Compared to Zimbabwe, REC rates were similar in South Africa, aPRR = 0.97 (95% CI: 0.90-1.04), p = 0.355, lower in Malawi, aPRR = 0.84 (95% CI: 0.78-0.91), p<0.001, and Uganda, 0.82 (95% CI: 0.73-0.91), p<0.001. Additionally, REC use was independently associated with education attained, primary versus higher education, aPRR = 1.10 (95% CI: 1.02-1.18), p = 0.013; marriage/stable union, aPRR = 1.10 (95% CI: 1.01-1.21), p = 0.039; no desire for another child, PRR = 1.10 (95% CI: 1.02-1.16), p = 0.016; infrequent sex (none in the last 3 months), aPRR = 1.24 (95% CI: 1.15-1.33), p<0001; and controlled HIV load (≤ 1000 copies/ml), PRR = 1.10 (95% CI: 1.02-1.19), p = 0.014. LARC use was independently associated with country (Zimbabwe ref: South Africa, PRR = 0.39 (95% CI: 0.26-0.57), p<0.001; Uganda, PRR = 0.65 (95% CI: 0.42-1.01), p = 0.054; and Malawi, aPRR = 0.87 (95% CI: 0.64-1.19), p = 0.386; HIV load (≤ 1000 copies/ml copies/ml), aPRR=1.73 (95% CI: 1.26-2.37), p<0.001; and formal/self-employment, aPRR = 1.37 (95% CI: 1.02-1.91), p = 0.027. CONCLUSIONS: Unintended pregnancy was common while use of effective contraception methods particularly LARCs was low among these African WLHIV. HIV viral load, education, sexual-activity, fertility desires, and economic independence are pertinent individual-level factors integral to the multi-level barriers to utilization of effective contraception among African WLHIV. National programs should prioritize strategies for effective integration of HIV and reproductive health care in the respective African countries.

ABSTRACT

Objective: To explore the experiences of Malawian women who underwent a human papillomavirus (HPV)-based screen-triage-treat algorithm for cervical cancer (CxCa) prevention. This algorithm included GeneXpert® HPV testing of self-collected vaginal samples, visual inspection with acetic acid (VIA) and colposcopy for HPV-positive women, and thermal ablation of ablation-eligible women. Method: In-depth interviews were conducted with participants of a trial that evaluated the feasibility of a HPV-based screen-triage-treat algorithm among women living with HIV and HIV negative women in Lilongwe, Malawi. Participants were recruited from 3 groups: 1) HPV-negative; 2) HPV-positive/VIA-negative; 3) HPV-positive/VIA-positive and received thermal ablation. Interviews explored baseline knowledge of CxCa and screening, attitudes towards self-collection, and understanding of test results. Content analysis was conducted using NVIVO v12. Results: Thematic saturation was reached at 25 interviews. Advantages of HPV self-collection to participants were convenience of sampling, same-day HPV results and availability of same-day treatment. There was confusion surrounding HPV-positive/VIA-negative results, as some participants still felt treatment was needed. Counseling, and in particular anticipatory guidance, was key in helping participants understand complex screening procedures and results. Overall, participants expressed confidence in the HPV screen-triage-treat strategy. Discussion: HPV testing through self-collected samples is a promising tool to increase CxCa screening coverage. A multi-step screening algorithm utilizing HPV self-testing, VIA triage and thermal ablation treatment requires proper counseling and anticipatory guidance to improve patient understanding. Incorporating thorough counseling in CxCa screening programs can change women's perspectives about screening, build trust in healthcare systems, and influence healthcare seeking behavior towards routine screening and prevention.

ABSTRACT

BACKGROUND: The World Health Organization recommends human papillomavirus (HPV) testing for primary cervical cancer screening, including among women living with HIV (WLWH). Low-and-middle-income countries account for 85% of the cervical cancer burden globally, yet have limited access to HPV-based screening, largely due to cost. This study aims to compare the performance of a rapid, isothermal amplification HPV assay (ScreenFire) to that of the Xpert HPV assay for the detection of HPV and cervical precancer among WLWH in Malawi. METHODS: We utilized stored self- and provider-collected specimens from a prospective cohort study of WLWH in Malawi from July 2020 to February 2022. Specimens were tested with both Xpert and ScreenFire HPV assays. The overall and within-channel non-hierarchical agreement between ScreenFire and Xpert was determined for both self- and provider-collected specimens. Hierarchical ScreenFire HPV positivity by channel was compared to Xpert for each histological diagnosis-cervical intraepithelial neoplasia grade 2 or worse (CIN2+) compared to
