RESUMO

The Microbicide Trials Network 042 study (MTN-042/DELIVER) is a two-arm, randomized, open-label Phase 3b trial that is evaluating the safety, adherence, and acceptability of the monthly ring and daily oral PrEP among HIV-uninfected pregnant people in four African countries. This analysis focuses on acceptability data captured qualitatively from a subset (n = 48) of the 150 people in the first cohort of the trial who were enrolled in late-stage pregnancy at 36 to 38 weeks gestational age and followed until after delivery. Single IDIs were conducted by trained interviewers at each clinic site using a semi-structured guide. Data excerpts of key codes pertaining to acceptability, pregnancy, and maternal health were summarized, reviewed and interpreted by multinational analyst teams. Although the product use period was relatively short, the data suggested several acceptability findings that may directly translate to longer durations of product use in pregnancy. The first was the overarching maternal sentiment that being able to protect both oneself and their baby was highly valued. The second was the importance of counseling support from providers not only because participants used methods that might generate side effects, but because pregnancy itself is a period with its own set of side effects. The third was that, similar to non-pregnant participants in other trials, here study products were generally liked and described as easy to use. Concerns about ring and oral PrEP use could be addressed with provider counseling and support and should form an essential component rollout among pregnant people.

RESUMO

Depression is associated with lower adherence to oral pre-exposure prophylaxis (PrEP) to prevent HIV, but data are not currently available on how depression may affect use of other HIV prevention methods including the dapivirine vaginal ring (DVR). We conducted a mixed methods study using data from the Microbicide Trials Network (MTN) 042/DELIVER (n = 558) and MTN-043/B-PROTECTED (n = 197) studies to describe the prevalence of depressive symptoms and explore how depressive symptoms may have influenced attitudes about use of the monthly DVR and once-daily oral PrEP tablet among pregnant and breastfeeding persons, respectively, in Malawi, South Africa, Uganda, and Zimbabwe. Eleven participants had high Edinburgh Postnatal Depression scores ≥ 10 in MTN-042/DELIVER (2%) and four participants (2%) in MTN-043/B-PROTECTED. In interviews with 9 participants who had high scores (6 DVR, 3 oral PrEP), those with depressive symptoms described overlapping stressors which were magnified by job loss and economic instability during the COVID-19 pandemic, and by experiences of pregnancy/postpartum. These participants experienced a lack of support from partners or family members, and conflict with partners related to trust, and infidelity. While we did not find evidence of a change in product adherence, there was a strong sense of commitment and motivation to use the study products for protection from HIV for participants themselves and their baby. Although lack of social support is usually an obstacle to adherence, in this study, the participants' lives and relationships seemed to have reinforced the need for HIV prevention and motivated women to protect themselves and their babies from HIV.

RESUMO

This study examines qualitative acceptability of the dapivirine vaginal ring (DVR) and oral daily pre-exposure prophylaxis (PrEP) among breastfeeding persons participating in Microbicide Trials Network 043/B-PROTECTED, a phase 3B safety and drug detectability study of DVR and oral PrEP in breastfeeding. A subsample of 52 participants were purposively sampled to participate in an in-depth interview (IDI). Breastfeeding participants found both study products to be acceptable, and easy to use. A common motivation for product use was to protect the baby from HIV, although participants' understanding of how the study drug would work to protect their babies was often unclear. While most participants did not report experiencing side effects, fears about side effects were common as both initial worries about how the study products would affect their health and the health of their baby, and increased anxiety that health issues experienced by them, or their baby were from the products.

RESUMO

We conducted a secondary analysis of discrete choice experiment (DCE) data from 395 couples enrolled in the Microbicide Trials Network (MTN)-045/CUPID study in Uganda and Zimbabwe to understand couple decision making around choice of multipurpose prevention technologies (MPTs) to prevent both HIV and pregnancy. Members of couples completed the same DCE, first separately then jointly, choosing between two hypothetical MPTs in a series of nine questions. Most couples either had similar preferences at the outset or had equal decision-making around MPTs (62%). Couples with male influence (17%) were more likely to use contraceptive pills with a male partner's knowledge and couples with female influence (21%) were less likely to have shared decision making about family planning. Males influenced discussion around MPT duration, side effects, menstrual changes, and how the vagina feels during sex. Decision making was relatively shared, though decisions around certain attributes were more likely to be dominated by male partners.

RESUMO

BACKGROUND: Adolescent girls and young women (AGYW) account for 29% of new HIV infections in Uganda despite representing just 10% of the population. Peer support improves AGYW linkage to HIV care and medication adherence. We evaluated the feasibility and acceptability of peer delivered HIV self-tests (HIVST) and oral pre-exposure prophylaxis (PrEP) to young women in Uganda. METHODS: Between March and September 2021, we conducted a pilot study of 30 randomly selected young women, aged 18-24 years, who had received oral PrEP for at least three months, but had suboptimal adherence as measured by urine tenofovir testing (< 1500 ng/ml). Participants were offered daily oral PrEP and attended clinic visits three and six months after enrollment. Between clinic visits, participants were visited monthly by trained peers who delivered HIVST and PrEP. Feasibility and acceptability of peer-delivered PrEP and HIVST (intervention) were measured by comparing actual versus planned intervention delivery and product use. We conducted two focus groups with young women, and five in-depth interviews with peers and health workers to explore their experiences with intervention delivery. Qualitative data were analyzed using thematic analysis. RESULTS: At baseline, all 30 enrolled young women (median age 20 years) accepted peer-delivered PrEP and HIVST. Peer delivery visit completion was 97% (29/30) and 93% (28/30) at three and six months, respectively. The proportion of participants with detectable tenofovir in urine was 93% (27/29) and 57% (16/28) at months three and six, respectively. Four broad themes emerged from the qualitative data: (1) Positive experiences of peer delivered HIVST and PrEP; (2) The motivating effect of peer support; (3) Perceptions of female controlled HIVST and PrEP; and (4) Multi-level barriers to HIVST and PrEP use. Overall, peer delivery motivated young women to use HIVST and PrEP and encouraged persistence on PrEP by providing non-judgmental client-friendly services and adherence support. CONCLUSION: Peer delivery of HIVST and oral PrEP was feasible and acceptable to this sample of young women with suboptimal PrEP adherence in Uganda. Future larger controlled studies should evaluate its effectiveness among African AGWY.

RESUMO

End-user input early in biomedical product development may optimize design to support high uptake and adherence. We interviewed 400 couples (800 total participants) in Uganda and Zimbabwe to assess their preferences for multipurpose prevention technologies (MPTs) for HIV and pregnancy prevention. Using a discrete choice experiment, couples made a series of choices between hypothetical MPTs, including oral tablets and vaginal rings, inserts, and films and completed an interviewer-administered questionnaire assessing sociodemographic and behavioral measures. Most couples preferred presented MPTs over male condoms. Couples' MPT choices in both countries were influenced most by the combination of product form and dosing frequency, with monthly dosing preferred over daily. Analysis highlighted differences by country as to which side effects were most important: Ugandan couples placed greater importance on effects on the vaginal environment during sex, whereas Zimbabwean couples placed more importance on changes to menstruation and other side effects (headache, cramps). Couples' preferences signaled an openness to new product forms and more frequent dosing if preferred characteristics of other attributes were achieved.

RESUMO

In the Phase IIIB MTN-025/HOPE open label extension trial, participants were offered the dapivirine vaginal ring as HIV prophylaxis, and those who accepted the ring received semi real-time individual adherence feedback, based on residual drug level (RDL) from returned rings, during Motivational Interviewing-based counseling. Counseling messages, based on the best knowledge at the time, framed RDL results in terms of ring use and HIV protection, from no use /no protection (0 RDL) to high use /high protection (3 RDL). At six HOPE sites, in-depth-Interviews (IDIs) about RDL were conducted with 64 participants who had received at least one RDL result. We found mixed interpretations of what the RDL meant and strong emotional reactions with a focus on the external validation of the level itself. Counseling was critical to help participants process their reactions to the RDL and make decisions accordingly (i.e., persistence, adherence improvement, and/or switching to another HIV prevention method). Providing drug adherence feedback was complex to implement yet proved useful as a component of a multi-pronged adherence support strategy.

RESUMO

As demonstrated by the Phase III clinical trial, MTN-020/ASPIRE, the monthly dapivirine vaginal ring is well tolerated and reduces the risk of HIV-1 as a woman-initiated prevention option. This analysis uses data from the follow-on MTN-032/Assessment of ASPIRE and HOPE Adherence (AHA) qualitative study to understand how perceptions (or misperceptions) of ring efficacy may have influenced behavior during ASPIRE, and affected intention to use the ring in future ring projects, specifically HOPE, the planned open-label extension study. Single in-depth interviews (n = 98) and 12 focus group discussions (n = 89) were conducted with women at seven sites in Malawi, South Africa, Uganda and Zimbabwe. Eligibility included participation in the ASPIRE active arm, and ring use for ≥ 3 months or at least 1 month if seroconversion occurred. Interviews were audio-recorded, transcribed into English, coded in Dedoose and thematically analyzed. Demographic and behavioral questionnaire data were summarized in Stata. Most AHA participants perceived the ring to be effective, and described simply trusting it or having confidence in it because they, or other participants in risky situations, remained HIV-uninfected. Participants described ring efficacy after receiving ASPIRE results as a binary assessment: the ring worked or not. Many did not remember exact efficacy percentages because of lack of comprehension or memory but recalled key details about age differences. The majority expressed interest in future ring use. There is a need to investigate improved ways of explaining placebo-controlled trials and efficacy to women in Sub-Saharan Africa. Now that ring efficacy, is known, these benefits must be well communicated, and understood by end-users and key stakeholders. Engagement with end-users to construct effective messages and to develop tools to measure understanding of partial efficacy will be essential.

RESUMO

The monthly dapivirine vaginal ring has proven efficacious in reducing HIV incidence in two Phase 3 clinical trials. When considering the potential future availability of the ring to the public, key questions remain about the feasibility of integrating the ring as an HIV prevention intervention into women's lives. We conducted qualitative mapping interviews (n = 66) among women enrolled in MTN-025/HOPE, an open-label trial conducted in Malawi, South Africa, Uganda and Zimbabwe, to examine how home environments influenced use of the dapivirine vaginal ring. Most women had secure places to store their rings including wardrobes, suitcases, and bags. The primary concerns for ring storage were potential tampering from children or rodents. Household overcrowding limited the privacy some women had which made removal and insertion of vaginal rings challenging. Despite these challenges, ring storage, insertion, and removal was feasible across social and living contexts.

RESUMO

BACKGROUND: Involvement of adolescent girls in biomedical HIV research is essential to better understand efficacy and safety of new prevention interventions in this key population at high risk of HIV infection. However, there are many ethical issues to consider prior to engaging them in pivotal biomedical research. In Uganda, 16-17-year-old adolescents can access sexual and reproductive health services including for HIV or other sexually transmitted infections, contraception, and antenatal care without parental consent. In contrast, participation in HIV prevention research involving investigational new drugs requires adolescents to have parental or guardian consent. Thus, privacy and confidentiality concerns may deter adolescent participation. We describe community perspectives on ethical considerations for involving adolescent girls in the MTN 034 study in Uganda. METHODS: From August 2017 to March 2018, we held five stakeholder engagement meetings in preparation for the MTN 034 study in Kampala, Uganda (NCT03593655): two with 140 community representatives, two with 125 adolescents, and one with 50 adolescents and parents. Discussions were moderated by the study team. Proceedings were documented by notetakers. Summary notes described community perspectives of adolescent participation in HIV research including convergent, divergent or minority views, challenges, and proposed solutions. RESULTS: Most community members perceived parental or guardian consent as a principal barrier to study participation due to concerns about adolescent disclosure of pre-marital sex, which is a cultural taboo. Of 125 adolescent participants, 119 (95%) feared inadvertent disclosure of sexual activity to their parents. Community stakeholders identified the following critical considerations for ethical involvement of adolescents in HIV biomedical research: (1) involving key stakeholders in recruitment, (2) ensuring confidentiality of sensitive information about adolescent sexual activity, (3) informing adolescents about information to be disclosed to parents or guardians, (4) offering youth friendly services by appropriately trained staff, and (5) partnering with community youth organizations to maximize recruitment and retention. CONCLUSIONS: Stakeholder engagement with diverse community representatives prior to conducting adolescent HIV prevention research is critical to collectively shaping the research agenda, successfully recruiting and retaining adolescents in HIV clinical trials and identifying practical strategies to ensure high ethical standards during trial implementation.

RESUMO

We assessed the interference between vaginal ring use and menses among women who participated in the qualitative component of the MTN-020/ASPIRE vaginal ring trial in Malawi, South Africa, Uganda and Zimbabwe (N = 214). A common reason for imperfect ring adherence and premature removal of the vaginal ring cited by participants related to vaginal bleeding or menses. Whereas self-reporting via survey questions suggested that the majority (60%) of women did not mind wearing the ring while menstruating, and did not remove it (91%) during menses, in the qualitative interviews women frequently described removing the ring during menses. Their reasons included hygiene, beliefs that the ring blocked the flow of menstrual blood, fears that the ring would come out with blood or during tampon removal, and concerns around an 'overburdened' vagina. Examining women's narratives and subjective experiences related to menstruation helps build a better understanding of factors affecting ring use and adherence.

RESUMO

BACKGROUND: The 'Primary HIV Prevention among Pregnant and Lactating Ugandan Women' (PRIMAL) randomized controlled trial aimed to assess an enhanced counseling strategy linked to extended postpartum repeat HIV testing and enhanced counseling among 820 HIV-negative pregnant and lactating women aged 18-49 years and 410 of their male partners to address the first pillar of the WHO Global Strategy for the Prevention of Mother-to-Child HIV transmission (PMTCT). This paper presents findings of qualitative studies aimed at evaluating participants' and service providers' perceptions on the acceptability and feasibility of the intervention and at understanding the effects of the intervention on risk reduction, couple communication, and emotional support from women's partners. METHODS: PRIMAL Study participants were enrolled from two antenatal care clinics and randomized 1:1 to an intervention or control arm. Both arms received repeat sexually transmitted infections (STI) and HIV testing at enrolment, labor and delivery, and at 3, 6, 12, 18 and 24 months postpartum. The intervention consisted of enhanced quarterly counseling on HIV risk reduction, couple communication, family planning and nutrition delivered by study counselors through up to 24 months post-partum. Control participants received repeat standard post-test counseling. Qualitative data were collected from intervention women participants, counsellors and midwives at baseline, midline and end of the study through 18 focus group discussions and 44 key informant interviews. Data analysis followed a thematic approach using framework analysis and a matrix-based system for organizing, reducing, and synthesizing data. RESULTS: At baseline, FGD participants mentioned multiple sexual partners and lack of condom use as the main risks for pregnant and lactating women to acquire HIV. The main reasons for having multiple sexual partners were 1) the cultural practice not to have sex in the late pre-natal and early post-natal period; 2) increased sexual desire during pregnancy; 3) alcohol abuse; 4) poverty; and 5) conflict in couples. Consistent condom use at baseline was limited due to lack of knowledge and low acceptance of condom use in couples. The majority of intervention participants enrolled as couples felt enhanced counselling improved understanding, faithfulness, mutual support and appreciation within their couple. Another benefit mentioned by participants was improvement of couple communication and negotiation, as well as daily decision-making around sexual needs, family planning and condom use. Participants stressed the importance of providing counselling services to all couples. CONCLUSION: This study shows that enhanced individual and couple counselling linked to extended repeat HIV and STI testing and focusing on HIV prevention, couple communication, family planning and nutrition is a feasible and acceptable intervention that could enhance risk reduction programs among pregnant and lactating women. TRIAL REGISTRATION: ClinicalTrials.gov registration number NCT01882998, date of registration 21st June 2013.

RESUMO

BACKGROUND: In biomedical prevention trials, correct and consistent use of the investigational product is crucial to determine efficacy. Product adherence in VOICE, a phase 2B randomized trial of a vaginal gel and oral tablets for HIV prevention, was low (~ 34%), yet self-reported adherence and retention was high (> 90%). This analysis from VOICE-D, a post-trial qualitative ancillary study, explores motivations to participate in VOICE, and possible sources of misalignment between the stated priorities of the trial and the participants. METHODS: VOICE-D enrolled 171 former VOICE participants to investigate, among other things, reasons for joining and remaining in the trial. Local language in-depth interviews and focus groups were transcribed and translated into English and coded and analyzed using NVivo. Data on motivation to join obtained from a VOICE termination visit survey of 106 participants were also analyzed to corroborate the VOICE-D findings. RESULTS: Participants primarily participated for personal health benefits (e.g. free healthcare and HIV testing) and reported remaining enrolled from a sense of commitment to the trial. Altruistic motivations were the most commonly stated motivation on the termination visit survey; qualitatively, many of those stating altruistic reasons also desired personal health benefits. Joining for financial reimbursement was not commonly mentioned. Social networks influenced recruitment and spread therapeutic misconception. CONCLUSIONS: Women's participation for personal health benefits highlighted their desire to monitor their HIV risk and overall health. Helping participants view use of investigational products as improving social capital and reminding participants of their study responsibilities may improve trial outcomes. Understanding the reasons for participating in studies will help to ensure alignment between priorities of researchers and participants.

RESUMO

Rumours may influence health-related behaviours, including the uptake of and adherence to HIV prevention products. This study assessed the safety and effectiveness of a vaginal ring delivering the antiretroviral dapivirine for HIV prevention in Africa. We explored negative rumours about study participation and the vaginal ring amongst study participants and their communities in Malawi, Uganda, South Africa and Zimbabwe. In total 214 women participated in either single or serial in-depth interviews, or a focus group discussion. Three key findings emerged in the data. Firstly, rumours reflected fears concerning the ring and trial participation. Given the historical-political context of the countries in which the trial was conducted, the ring's investigational nature and its foreign origin, ring use was rumoured to cause negative health outcomes such as cancer and infertility and to be associated with practices such as witchcraft or Satanism. The salience of these rumours varied by country. Secondly, rumours reportedly affected participants' adherence to the ring, and other women's willingness to participate in the study. Finally, participants reported that participant engagement activities helped address rumours, resulting in enhanced trust and rapport between staff and participants.

RESUMO

BACKGROUND: Effective Prevention of Mother to child Transmission of HIV (PMTCT) relies heavily on follow-up of HIV-infected women and infants from antenatal, through postnatal, to the end of the breastfeeding period. In Uganda, postnatal (PNC) follow-up remains below 50 % creating a missed opportunity for linkage to comprehensive HIV care and early infant diagnosis (EID). We evaluated the use of HIV infected peer mothers (peers), community lay persons and Village health team (VHT) members to improve PNC follow up and EID in urban and rural health units. METHODS: Study participants were HIV-infected women recruited from antenatal clinics at three urban clinics (Mulago, Rubaga and Mengo hospitals) and one rural health centre (Mpigi Health centre IV) between January and September 2010. The women were followed through delivery and the mother-infant pairs for the 6-week postnatal visit and up to 14 weeks for EID. Peers, community lay persons and VHT members were identified and trained in basic PMTCT and reproductive health (RH). They were then assigned to study clinic to support and follow study participants, their partners and infants through provision of health education, counseling, home visits, and phone call reminders. Six week PNC attendance was measured as a proportion of mother-infant pairs that returned for the 6-week postnatal follow up visit (5-8 weeks) while EID was measured as the proportion of HIV-exposed live birth that had an HIV test done by 14 weeks of age. Data at baseline (one year before the intervention) was compared with that during the one year study period among study participants and HIV infected women and their HIV-exposed infants in the whole clinic population. RESULTS: A total of 558 HIV-infected pregnant women were recruited for the study, 47 mother-infant pairs were censured before 6 weeks due to stillbirth (14), infant death < 6 weeks (23), death of participant (04) and loss to follow up before delivery (6). 401/511 (78.5 %) of mother-infant pairs returned to the study clinics at six-week, while 441/511 (86.3 %) infants were tested for HIV infection by 14 weeks of age. The baseline six-week PNC follow up was 37.7 % and increased during the study period to 78.5 % and 39.1 % among study participants and whole clinic population respectively, an incremental difference of 39.4 % (P < 0.001). EID increased from a baseline of 53.6 % to 86.3 % and 65.8 % among study and whole clinic population respectively during the study period, an incremental difference of 20.5 % (P < 0.001). CONCLUSIONS: Use of peers, community lay persons and VHT members led to a significant increase in six-week postnatal follow up of HIV infected women and EID among HIV exposed infants in the four study clinics. Our study supports the use of peers to improve early postnatal follow up and EID and should be implemented in other health units to support the PMTCT cascade.

RESUMO

INTRODUCTION: Young women in sub-Saharan Africa account for two-thirds of all new HIV infections and face high rates of unintended pregnancy. Multipurpose prevention technologies (MPTs) are promising products under development that are designed to simultaneously prevent HIV and unintended pregnancy. Since MPTs will be used in the context of sexual relationships, ensuring acceptability and use requires understanding the role of male partners in MPT use decision-making. METHODS: This paper draws on qualitative data from 39 couples enrolled in the Microbicide Trials Network (MTN) 045 study, conducted in 2019-2020. Partners completed a discrete choice experiment (DCE), first separately and then jointly, to measure preferences for future MPT attributes and then completed a qualitative interview. We also draw on quantitative data from interviewer observation about who dominated the decision-making process during the joint DCE. Content analysis was used to examine (1) how couples made decisions on existing non-MPT HIV and pregnancy prevention products; (2) how couples made decisions on future ideal-MPT product during the DCE; and (3) how these decision-making processes varied by decision-making dominance (10 male, 10 female and 19 equal) and interview type (19 joint and 20 separate). RESULTS: Existing non-MPT product decisions focused on trust between partners and product attributes, while future ideal-MPT product decisions exclusively focused on product attributes. Across existing and future products, preferences for product attributes varied by gender. Male partners were most concerned with limiting side effects impacting sexual pleasure, female partners were most concerned with limiting side effects causing physical symptoms and both were concerned with the return to fertility. Across all dominance and interview types, couples reported making decisions together and female partners were often able to negotiate with male partners for their preferred product or set of product attributes. CONCLUSIONS: Research activities in this study provided an opportunity for couples to openly present their product attribute preferences to their partner, learn about their partner's attribute preferences, negotiate for their ideal set of attributes and ultimately choose attributes that benefited the couple without disempowering the female partner. Future research should focus on the utility of couple-based decision-making aids or similar tools for facilitating joint MPT decision-making.

RESUMO

Body mapping methods are used in sexual and reproductive health studies to encourage candid discussion of sex and sexuality, pleasure and pain, sickness and health, and to understand individuals' perceptions of their bodies. VOICE-D, a qualitative follow-up study to the VOICE trial, developed and used a body map tool in the context of individual in-depth interviews with women in South Africa, Uganda, and Zimbabwe. The tool showed the outline of a nude female figure from the front and back perspective. We asked women to identify, label, and discuss genitalia and other body parts associated with sexual behaviors, pain, and pleasure. Respondents could indicate body parts without having to verbalize potentially embarrassing anatomical terms, enabling interviewers to clarify ambiguous terminology that may have otherwise been open to misinterpretation. Body maps provided women with a non-intimidating way of discussing and disclosing their sexual practices, and minimized miscommunication of anatomical and behavioral terminology.

RESUMO

INTRODUCTION: Women in sub-Saharan Africa spend a substantial portion of their reproductive lives pregnant and/or breastfeeding (P/BF), yet they have limited options to prevent HIV during these maternal stages. In preparation for phase 3b prevention trials in P/BF women, we explored attitudes about using a vaginal ring or oral pills for pre-exposure prophylaxis (PrEP), perceptions of HIV risk during P/BF and key influences on future PrEP use. METHODS: In 2018, we conducted 16 single-sex focus group discussions (FGDs) with community- and clinic-recruited HIV-uninfected women, currently or recently P/BF, aged 18 to 40, and men with (currently or recently) P/BF partners, aged 18+. Participants completed a behavioural questionnaire, viewed an educational video and handled prototype placebo products. FGDs were conducted in local languages and transcribed, coded and analysed, using a socio-ecological framework, for key influences on willingness to use products, HIV risk perceptions and opinions on product attributes. RESULTS: Of the 128 participants (65 women, 63 men) 75% lived with their partner and 84% had a child. Women reported the most important influencers when P/BF were partners, and all stated that health decisions when P/BF are typically made jointly (e.g. medication use; ante/postnatal and baby care). There was consensus that P/BF women are at high risk for HIV, primarily because of their partner's infidelities, and new prevention options were welcomed. Participants valued multiple options and stated that woman's personal preference would be key to product choice. Anticipated concerns about products included risk of miscarriage, impact on infant development, complications during delivery and adequate production or taste of breastmilk. Specific perceived disadvantages emerged for the ring (e.g. vaginal discomfort, difficulty inserting/removing) and for pills (e.g. nausea/vomiting) that may be exacerbated during pregnancy. Health care providers' (HCPs) knowledge and approval of product use during P/BF was needed to mitigate anticipated fears. CONCLUSIONS: Participants perceived pregnancy and breastfeeding as high HIV risk periods and valued new prevention options. HIV protection of the mother-child dyad, safety of the baby, and ultimately, health of the family were paramount. Endorsement by HCPs and support from partners were key to future product acceptance. Participants recommended involving partners and HCPs in sensitization efforts for future trials.

RESUMO

BACKGROUND: The 'Primary HIV Prevention among Pregnant and Lactating Ugandan Women' (PRIMAL) study aimed to assess the effectiveness of an enhanced HIV counseling intervention for preventing HIV acquisition among HIV-uninfected mothers during pregnancy and throughout the breastfeeding period. METHODS: We conducted an unblinded randomized control trial between 22 February 2013 and 22 April 2016 to assess the effectiveness of an extended repeat HIV testing and enhanced counseling (ERHTEC) intervention aimed at preventing primary HIV infection among HIV-uninfected pregnant and lactating women in Uganda. HIV-uninfected pregnant women aged 15-49 were enrolled 1:1 individually or in couples together with their partner. Enrolled women and couples were randomized 1:1 to an intervention (ERHTEC) or control (extended repeat HIV testing and standard counseling) group and followed up to 24 months postpartum or six weeks past complete cessation of breastfeeding, whichever came first. Both groups were tested for sexually transmitted infections (STIs) and HIV at enrollment, delivery, 3 and 6 months postpartum and every 6 months thereafter until the end of follow-up. The intervention group received enhanced HIV prevention counseling every 3 months throughout follow-up. The control group received standard counseling at the time of HIV retesting. Both intervention and control couples were offered couple HIV testing and counseling at all study visits. MAIN OUTCOME MEASURES: Frequency of condom use and incidence of HIV, syphilis, gonorrhea, chlamydia and trichomoniasis over follow-up. RESULTS: Between February 2013 and April 2014, we enrolled 820 HIV-uninfected pregnant women presenting for antenatal care individually (n = 410) or in couples (n = 410 women and 410 partners) in one urban and one rural public Ugandan hospital. Women's median age was 24 years (IQR 20-28 years). At baseline, participants did not differ in any socio-demographic, reproductive health, HIV testing history, sexual behavior, medical history or STI status characteristics; 96% (386/402) of couples were tested and counseled for HIV together with their partners at enrolment, 2.1% (7/329) of whom were found to be HIV-infected. Six hundred twenty-five (76%) women completed follow-up as per protocol (S1 Protocol). Women were followed for an average of 1.76 years and cumulated 1,439 women-years of follow-up or 81% of the maximum 1,779 women-years of follow-up assuming no dropouts. Men were followed for an average of 1.72 years. The frequency of consistent condom use and the proportion of women who used condoms over the last 3 months or at last vaginal sex increased substantially over follow-up in both arms, but there were no statistically significant differences in increases between the intervention and control arms. During follow-up, on average 42% (range 36%-46%) of couple partners were counseled together. Between 3.8% and 7.6% of women tested positive at any follow-up visit for any STI including syphilis, gonorrhea, C. trachomatis or T. vaginalis. Four women (two in each arm) and no enrolled men became infected with HIV, representing an overall HIV incidence rate of 0.186 per 100 person-years. Three of the women seroconverters had enrolled individually, one as a couple. At or before seroconversion, all four women reported their partners had extramarital relationships and/or had not disclosed their suspected HIV-infected status. There were no statistically significant differences between study arms for STI or HIV incidences. CONCLUSIONS: A sustained enhanced HIV prevention counseling intervention for up to 2 years postpartum among pregnant and breastfeeding women did not have a statistically significant effect on condom use or HIV incidence among these women. However, in both study arms, condom use increased over follow-up while STI and HIV incidence remained very low when compared to similar cohorts in and outside Uganda, suggesting that repeat HIV testing during breastfeeding, whether with enhanced or standard counseling, may have had an unintended HIV preventive effect among pregnant and lactating women in this setting. Further research is needed to verify this hypothesis. TRIAL REGISTRATION: ClinicalTrials.gov NCT01882998.

RESUMO

BACKGROUND: HIV and pregnancy prevention are dual health priorities for women, and particularly in sub-Saharan Africa. Drug-eluting fibers offer a dosage form that combines HIV prevention and contraception, but early understanding of end-user perspectives is critical to avoid misalignment between products being developed and preferred product attributes. METHODS: Focus group discussions (FGDs) were conducted in South Africa, Uganda and Zimbabwe, among 55 women who had used vaginal products in previous trials. Participants were given the opportunity to feel a sample of electrospun nanofiber (the fabric), see how it dissolves, and give feedback on shape, size and other attributes. Women were also asked to compare the fabric to vaginal gel and film. RESULTS: Three key themes regarding the acceptability of the fabric emerged: 1) look and feel of the product undissolved vs. undissolved, 2) expected effect on sex, and 3) convenience and ease of use. Upon being presented with the fabric, women were initially distrustful, seeing it as undesirable for vaginal insertion. Women generally approved of the product once they saw it dissolve. However, they stressed the importance of the product not interfering with sex by altering the vaginal environment. Women also reacted favorably to the perceived convenience of the fabric, particularly with regards to storage and transport, perceived ease of insertion and use, and dosing regimen. CONCLUSION: Multipurpose prevention technologies, and nanofibers in particular, should be developed with an eye to minimizing impact on sex while maximizing convenience, and presented in such a way as to emphasize non-abrasiveness and ease of dissolution.
