HIV pre-exposure prophylaxis use during periods of unprotected sex among female sex workers in Tanga city, Tanzania: a control arm analysis of the pragmatic quasi-experimental trial. Front Public Health 2024; 12:1405765. [PMID: 39081360 PMCID: PMC11286493 DOI: 10.3389/fpubh.2024.1405765] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2024] [Accepted: 07/03/2024] [Indexed: 08/02/2024] Open
Abstract
Background Pre-exposure prophylaxis (PrEP) prevention-effective adherence is of critical importance but challenging particularly among key populations where periods of high HIV risk are frequent. We assessed the use of PrEP with reference to periods of unprotected sex among female sex workers in the city of Tanga. Methods This was part of the pragmatic quasi-experimental trial for HIV PrEP rollout in Tanzania involving a control cohort of 313 female sex workers aged ≥18 years recruited by respondent-driven sampling and followed for 12 months. PrEP use and periods of condomless or unprotected sex were assessed at the 6th and 12th month of follow-up. Prevention-effective adherence was defined as PrEP use of ≥2 pills/week and ≥6 pills/week for anal and vaginal condomless sex. Multivariable modified Poisson regression was conducted to determine factors influencing PrEP use (≥2 pills/week). Results Overall, 59.2 and 45.9% of participants had unprotected anal and vaginal sex with a client, respectively. The prevention-effective adherence for anal sex ranged from 8.0% (months 6) to 10.0% (months 12) while that of vaginal sex was from 10.1% (month 6) to 3.8% (month 12). Participants who lived with friends were 25.5 times more likely to use ≥2 PrEP doses per week than those who lived alone (aPR = 25.5; 95%CI: 2.55-255.42, p = 0.006). Compared to self-reporting poor health status, self-reporting good health status significantly increased the use of ≥2 PrEP doses per week (aPR = 17.4; 95%CI: 3.01-101.02, p = 0.001). Refusing condomless sex with a steady partner increased the likelihood of using ≥2 PrEP doses per week than accepting condomless sex with a steady partner (aPR = 11.2; 95%CI: 1.55-80.48, p = 0.017). The prevalence of using ≥2 PrEP doses per week was less among participants accepting condomless sex at high pay than those who refused (aPR = 0.1; 95%CI: 0.03-0.26, p = 0.000). Conclusion Use of PrEP during periods of unprotected sex was rare among female sex workers. Living with friends, self-reporting good health status, and refusing condomless sex with steady partners were associated with increased use of ≥2 PrEP doses per week. However, accepting condomless sex for increased payment was associated with reduced use of ≥2 PrEP doses per week. This calls for an in-depth study to understand the perspectives and circumstances shaping poor adherence during periods of unprotected sex among female sex workers.

Abstract
Background and Objective The discovery of innovative pharmacological preventative measures in Human Immunodeficiency Virus transmission has boosted optimism in the successful control of HIV/AIDS with the objective of eradication and the end of the epidemic. Hence, assessing the effect of pre-exposure prophylaxis (PrEP) on HIV prevention among key populations (KPs) is imperative in advancing the conversation on ending HIV/AIDs. Methods This was a cross-sectional study using data from KPs (female sex workers (FSWs), men who have sex with men (MSM), and people who inject drugs (PWIDs) enrolled in Heartland Alliance Ltd/GTE One Stop Shops (OSS) between May 2019 and April 2023 in the six selected Nigerian states (Lagos, Bayelsa, Cross River, Akwa Ibom, Jigawa, and Niger). Data were cleaned in a spreadsheet and analyzed using IBM-SPSS version 28.0. Descriptive statistics, including frequency and percentage calculations, were conducted to analyze the dataset. Additionally, cross-tabulation analysis was performed, with a significance level set at 0.05, to explore relationships between variables. Results The study population comprised 13,580 participants, with 56.1% female. In all, 43.9% were aged 18-35 and 97.3% were single. Among the three KPs examined, FSW was the largest subgroup (50.8%), followed by MSM (28.1%) and PWID (21.1%). Most participants had been on PrEP for 0-3 months (87.8%), and PrEP was initiated for 81.6% due to high-risk sexual behaviors and 9.9% for serodiscordant relationship reasons. Most of them were enrolled in community healthcare settings (97.0%). The results showed that 99.9% remained HIV negative, while only two (0.01%) were seroconverted while on PrEP. The HIV-positive cases did not complete one-month PreP treatment, comprising an FSW and a PWID. Recent HIV contact or poor compliance with PrEP medication are two possible causes of seroconversion. Conclusion and Global Health Implications The findings underscore the significance of integrating PrEP into a comprehensive HIV prevention approach, including newer molecules that will improve adherence and the necessity of ongoing monitoring and support for PrEP users. With these insights, there can be an advocacy for promoting PrEP among the KPs as a vital component of Nigeria's HIV prevention strategy.

Barriers and facilitators to uptake and persistence on prep among key populations in Southern Province, Zambia: a thematic analysis. BMC Public Health 2024; 24:1617. [PMID: 38886691 PMCID: PMC11184712 DOI: 10.1186/s12889-024-19152-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 06/14/2024] [Indexed: 06/20/2024] Open
Abstract
BACKGROUND Especially in high HIV prevalence contexts, such as Zambia, effective biomedical prevention tools are needed for priority populations (PPs), including key populations (KPs), who are at higher risk. HIV pre-exposure prophylaxis (PrEP) has been scaled up nationally in Zambia, but little is known about barriers to PrEP use among specific PPs to date. METHODS To understand barriers and facilitators to PrEP use in Zambia, we conducted a qualitative case study of PrEP services to PPs including sero-discordant couples (SDCs), female sex workers (FSWs), and men who have sex with men (MSM) in Livingstone. The study conducted in 2021 included in-depth interviews (n = 43) guided by the socio-ecological model, and focus group discussions (n = 4) with clinic and community-based providers and PrEP-eligible clients including users and non-users across PP groups. We used thematic analysis to analyze data using codes derived both deductively and inductively. RESULTS We found multilevel barriers and facilitators to PrEP use. Cross-cutting barriers shared across PP groups included amplifying effects of PrEP being mistaken for antiretroviral drugs used to treat HIV, including anticipated stigma, and concerns about side-effects based on both misinformation and experience. In addition, stigmatized identities, particularly that of MSM, served as a barrier to PrEP use. The fear of being mislabeled as having HIV was of greatest concern for FSWs. Facilitators to PrEP use primarily included the importance of confidential, KP-sensitive services, and the role of informed, supportive family, friends, and peers. Participants across all PP groups urged expanded education efforts to increase awareness of PrEP within the general population toward mitigating concerns of being mislabeled as living with HIV. CONCLUSION To our knowledge, this is the first qualitative study of the PrEP cascade among multiple PPs in Zambia. This study provides important explanation for the low rates of PrEP continuation found in earlier demonstration trials among KPs in Zambia. The study also offers recommendations for programming efforts going forward such as inclusive PrEP awareness campaigns, expanded KP sensitivity training, and related efforts to thwart PrEP stigma while expanding access.

Abstract
BACKGROUND As oral PrEP scales up in Nigeria, information about uptake, use pattern and client preference in a real-world, implementation setting is invaluable to guide refining service provision and incorporation of oral PrEP and other prevention measures into routine health services. To add to this body of knowledge, our study examines factors associated with discontinuation of PrEP among HIV negative individuals across two large scale programs in Nigeria. METHODS Using program implementation data from two large-scale HIV projects in Akwa Ibom and Cross River states in Nigeria between January 2020 and July 2021, we used logistic regression to explore factors associated with early discontinuation (i.e., stopping PrEP within one month of starting) among HIV-negative individuals who initiated PrEP in the programs. RESULTS Of a total of 26,325 clients; 22,034 (84%) discontinued PrEP within the first month. The odds of PrEP discontinuation were higher among clients who enrolled in community-based distribution sites (aOR 2.72; 95% C.I: 2.50-2.96) compared to those who enrolled in program-supported facilities and never married (aOR 1.76; 95% C.I: 1.61-1.92) compared to married clients. Clients who initiated PrEP because of high-risk sexual behaviour (aOR 1.15, 95% C.I 1.03-1.30) or inconsistent use or non-use of condoms (aOR 1.96, 95% C.I 1.60-2.41) had greater odds of discontinuing PrEPthan those who initiated PrEP because they were in a serodifferent relationship. CONCLUSION The behavioural and demographic factors associated with early discontinuation of PrEP suggest that risk stratification of pre-initiation and follow up counselling may be helpful in raising continuation rates. On the service delivery side, strategies to strengthen follow-up services provided by community-based distribution sites need to be introduced. Overall, the low continuation rate calls for a review of programmatic approaches in provision of PrEP services in Nigeria.

Abstract
BACKGROUND Uganda is burdened by high unintended and teen pregnancies, high sexually transmitted infections, and harm caused by unsafe abortion. OBJECTIVES Explore factors influencing sexual and reproductive health and rights (SRHR) in Uganda by synthesizing evidence from qualitative studies using a scoping review. ELIGIBILITY CRITERIA Original qualitative peer-reviewed research studies published between 2002 and 2023 in any language exploring factors influencing SRHR in Uganda. SOURCES OF EVIDENCE Eight databases searched using qualitative/mixed methods search filters and no language limits. CHARTING METHODS Information extracted included author, article title, publication year, study aims, participant description, data collection type, sample size, main findings, factors at the individual, interpersonal, community, and policy levels, implications for SRHR in Uganda, and study limitations. Quality of the selected articles was assessed using the Critical Appraisal Skills Programme tool. RESULTS One hundred seventy-three studies met inclusion criteria. At the individual level, knowledge and attitudes toward SRHR, risky sexual behavior, and access to maternal SRHR services were identified as critical factors influencing health outcomes. Interpersonal factors included communication with sexual partners and relationships with family, school, and community members. Healthcare organization factors included adolescent access to education, SRHR services, and HIV prevention. Cultural and social factors included gendered norms and male involvement in SRHR. Policy-level factors included the importance of aligning policy and practice. CONCLUSIONS Multiple factors at individual, interpersonal, community, healthcare, cultural, and policy levels were found to influence SRHR in Uganda. The findings suggest that interventions targeting multiple levels of the socio-ecological system may be necessary to improve SRHR outcomes. This review highlights the need for a holistic approach that considers the broader socio-ecological context. Reducing identified gaps in the literature, particularly between policy and practice related to SRHR, is urgently needed in Uganda. We hope this review will inform the development of policies and interventions to improve SRHR outcomes.

Abstract
BACKGROUND East and Southern Africa have the highest HIV incidence and prevalence in the world, with adolescents and young adults being at the greatest risk. Despite effective combination prevention tools, including the recently available pre-exposure prophylaxis (PrEP), HIV incidence among adolescents and young adults in Uganda remains high, and PrEP use remains low. Mental health and substance use (behavioral health) play a role in sexual behavior and decision-making, contributing to an increase in the risk for acquiring HIV. Interventions that target multiple HIV risk factors, including sexual and mental health and problematic substance use, are crucial to ending the HIV epidemic. Yet few interventions addressing HIV related health disparities and comorbidities among adolescents and young adults in East and Southern Africa currently exist. OBJECTIVE This study aims to evaluate the acceptability and feasibility of Kirabo, an SMS text message intervention informed by the information, motivation, and behavior model and to be disseminated through secondary schools. The study will gather preliminary estimates of Kirabo's effectiveness in increasing HIV testing and linking users to mental health counselors. METHODS We identified Mobile 4 Reproductive Health for adaptation using the assessment, decision, administration, production, topical experts, integration, training, testing (ADAPT-ITT) framework. Mobile 4 Reproductive Health is an evidence-based automated 2-way SMS text messaging and interactive voice response platform that offers sexual and reproductive health information and links users to HIV clinics in East Africa. Through ADAPT-ITT we refined our approach and created Kirabo, an SMS text message-based intervention for linking adolescents and young adults to health services, including HIV testing and mental health counseling. We will conduct a 2-arm randomized controlled trial in Masaka, Uganda. Adolescents (N=200) will be recruited from local schools. Baseline sociodemographic characteristics, HIV test history, and behavioral health symptoms will be assessed. We will evaluate acceptability and feasibility using surveys, interviews, and mobile phone data. The preliminary efficacy of Kirabo in increasing HIV testing and linking users to mental health counselors will be evaluated immediately after the intervention and at the 3-month follow-up. We will also assess the intervention's impact on self-efficacy in testing for HIV, adopting PrEP, and contacting a mental health counselor. RESULTS Intervention adaptation began in 2019. A pretest was conducted in 2021. The randomized controlled trial, including usability and feasibility assessments and effectiveness measurements, commenced in August 2023. CONCLUSIONS Kirabo is a tool that assists in the efforts to end the HIV epidemic by targeting the health disparities and comorbidities among adolescents in Uganda. The intervention includes local HIV clinic information, PrEP information, and behavioral health screening, with referrals as needed. Increasing access to prevention strategies and mitigating factors that make adolescents and young adults susceptible to HIV acquisition can contribute to global efforts to end the HIV epidemic.

Abstract
PURPOSE This study aimed to describe pre-exposure prophylaxis (PrEP) for HIV discontinuation in adolescent men who have sex with men (aMSM) and adolescent transgender women (aTGW) and to identify factors associated with discontinuation. METHODS The PrEP1519 study included a cohort of aMSM and aTGW aged 15-19 years old, and it was conducted in three large Brazilian capital cities. For this analysis, we included adolescents who initiated PrEP. PrEP discontinuation was defined as no possession of PrEP pills for >90 days. Kaplan-Meier curves were used to analyze the probabilities of discontinuation, and survival distributions stratified by covariates were compared using log-rank or Wilcoxon tests. Cox regression models were used to estimate the adjusted hazard ratio (aHR) with a 95% confidence interval (95% CI). RESULTS We included 908 adolescents, 829 (91.30%) aMSM and 79 (8.70%) aTGW, most of whom were 18-19 years (80.29%). The incidence rate of discontinuation was 75.6 per 100 person-years. The probability of discontinuation was 52.61% in the first year. The multivariate analysis demonstrated that the aTGW (aHR = 1.63; 95% CI: 1.02-1.64) and adolescents with a medium (aHR = 1.29; 95% CI: 1.02-1.64) or low (aHR = 1.65; 95% CI: 1.29-2.12) perceived risk of HIV infection had an increased risk of discontinuation, whereas the adolescents with a partner living with HIV had a lower risk of discontinuation (aHR = 0.57; 95% CI: 0.35-0.91). DISCUSSION Adolescents with a high risk for discontinuation may need additional support that emphasizes the value of PrEP as a tool for HIV prevention because PrEP discontinuation was associated with a disconnect between HIV risk perception and HIV prevention.

Abstract
PURPOSE OF REVIEW East and Southern Africa are the epicenter of the HIV epidemic. High HIV incidence rates among adolescent girls and young women (AGYW) remain stable over the last decade despite access to daily oral PrEP. Some settings have experienced high PrEP uptake among AGYW; however, discontinuation has been high. This review sought to understand drivers of PrEP discontinuation in this population in order to identify potential mechanisms to facilitate PrEP restart and optimize PrEP use. RECENT FINDINGS Drivers of PrEP discontinuation included low perceived HIV acquisition risk, PrEP-associated side effects, pill burden, family/sexual partner disapproval, lack of/intermittent sexual activity, PrEP use stigma, fear of intimate partner violence, misinformation about long-term PrEP use, and limited/inconsistent access to PrEP. The most frequently reported driver of PrEP discontinuation was low perceived HIV acquisition risk. This indicates that innovative interventions to help AGYW recognize their HIV risk and make informed decisions about PrEP use are urgently needed.

Multi-level Factors Driving Pre-exposure Prophylaxis Non-initiation Among Young Women at High Risk for HIV in Kenya. AIDS Behav 2023; 27:106-118.

Abstract
Few studies have focused on understanding pre-exposure prophylaxis (PrEP) non-initiation among young, high-risk women in sub-Saharan Africa. This study aimed to qualitatively explore why young women in Kenya at high-risk for HIV chose not to enroll in a PrEP adherence trial. We performed 40 semi-structured interviews with young high-risk women assessing concerns about PrEP and/or study participation. We also assessed community-level factors influencing decision-making around PrEP through 10 focus groups involving peers, young men, caregivers, and community leaders. Our qualitative data reflect the complexity of navigating barriers preventing PrEP initiation in settings where taking PrEP may be perceived as immoral behavior. Framed within the context of risk perception, the decision to start PrEP may run counter to the potential risk of losing support from one's community. Our findings suggest that approaches addressing social norms, while de-medicalizing HIV prevention services, are needed to further increase PrEP uptake among young Kenyan women.

Alignment of PrEP adherence with periods of HIV risk among adolescent girls and young women in South Africa and Zimbabwe: a secondary analysis of the HPTN 082 randomised controlled trial. Lancet HIV 2022; 9:e680-e689. [PMID: 36087612 PMCID: PMC9530001 DOI: 10.1016/s2352-3018(22)00195-3] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 06/27/2022] [Accepted: 06/29/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Adolescent girls and young women in southern and eastern Africa have adherence challenges with daily oral HIV pre-exposure prophylaxis (PrEP). High adherence is most important during periods of HIV risk (prevention-effective adherence). We aimed to describe HIV risk behaviour and to understand patterns in PrEP adherence during periods of risk among adolescent girls and young women from sub-Saharan Africa. METHODS We did a secondary analysis of the HPTN 082 trial, an open-label, interventional, randomised controlled trial of sexually active adolescent girls and young women (aged 16-25 years) testing negative for HIV in Johannesburg and Cape Town, South Africa, and in Harare, Zimbabwe. The primary outcomes were high cumulative PrEP adherence, dichotomised as intracellular tenofovir diphosphate concentrations of at least 700 fmol/punch in dried blood spots at weeks 13, 26, and 52, and high recent PrEP adherence, dichotomised as plasma tenofovir concentrations of at least 40 ng/mL at weeks 13, 26, and 52, among participants who accepted PrEP. We collected data on sexual behaviour every 3 months. We categorised visits into a binary variable of any HIV risk based on condomless sex, more than one sexual partner, primary partner's HIV status and antiretroviral use, transactional sex, drug or alcohol use around sexual activity, and laboratory-diagnosed STIs. We used generalised estimating equations to evaluate associations between HIV risk (reflecting behaviour during the previous 3 months) and high cumulative and recent adherence to PrEP and any PrEP use (quantifiable drug concentrations). The trial is registered with ClinicalTrials.gov, NCT02732730. FINDINGS Between Oct 12, 2016, and Oct 25, 2018, 451 women were recruited, and 427 participants (median age 21·0 years [IQR 19·0-22·0]) were eligible for inclusion in this analysis. The proportion of participants reporting at least one HIV risk factor decreased significantly over follow-up, from 364 (85%) participants at enrolment, 226 (60%) at week 13, and 243 (65%) at week 26, to 224 (61%) at week 52 (p<0·0001). Any HIV risk was significantly associated with high PrEP adherence, measured by both tenofovir diphosphate concentrations of at least 700 fmol/punch (adjusted relative risk 1·57 [95% CI 1·09-2·25]; p=0·014) and plasma tenofovir concentrations of at least 40 ng/mL (1·36 [1·11-1·65]; p=0·0025). Any HIV risk was also associated with quantifiable concentrations of tenofovir diphosphate (1·15 [1·03-1·29]; p=0·013) and tenofovir (1·27 [1·09-1·49]; p=0·0022). We observed significant dose-response relationships between number of HIV risk factors and PrEP drug concentrations. INTERPRETATION The association between any HIV risk and high PrEP adherence suggests that adolescent girls and young women were able to use PrEP during periods of risk, an indicator of prevention-effective PrEP adherence. Our findings support a shift in the PrEP framework to acknowledge prevention-effective adherence practices, which might improve PrEP delivery and adherence support for adolescent girls and young women in HIV-endemic settings.

Abstract
A substantial proportion of heterosexually acquired HIV infections in the U.S. occur between partners in primary relationships characterized by mixed HIV status. The U.S. Centers for Disease Control and Prevention have issued guidelines prioritizing HIV-serodifferent couples for primary HIV prevention, including treatment-as-prevention and pre-exposure prophylaxis (PrEP). Yet, very little research has been conducted to understand the perspectives and practices of HIV-serodifferent couples regarding HIV prevention strategies in the U.S. To help fill this gap, we conducted a mixed methods study with 27 mostly Black/African American and Latinx HIV-serodifferent heterosexual couples residing in New York City to explore their knowledge, attitudes, practices, and perspectives regarding combination HIV prevention, including condoms, PrEP and viral control. All couples expressed the desire to maintain viral suppression in the HIV-positive partner, which was not always achieved. There was considerable heterogeneity in the use of HIV prevention methods by couples; and several patterns emerged that were largely driven by gender and relationship dynamics. Female partners, in particular, expressed high levels of anxiety around transmission of HIV and thus desired multiple methods of protection. Healthcare providers should consider couples' psychosocial well-being, relationship quality, and other motivational factors when helping to tailor HIV preventative care for mixed-status couples.

Abstract
The UNAIDS objective for 2020 was 500,000 new HIV-1 infections per year; however, the latest annual reported data confirmed 1.7 million new HIV-1 infections in that year. Those data evidences the need for new prevention strategies and prophylactic treatments. This prevention crisis occurred in spite of the knowledge and availability of efficient prevention strategies. The G2-S16 is a microbicidal polyanionic carbosilane dendrimer currently being tested for topical vaginal application, which has been shown to be efficient in the prevention of HIV-1 infection. However, safety tests were lacked. For this purpose, we injected intravenously G2-S16 dendrimer to CD1 mice, thereby analyzing the hemogram, blood biochemical markers of systemic damage, accumulation in the organs and organ-tissue damage in heart, spleen, kidney, liver and brain. This work shows that even if the G2-S16 dendrimer penetrates the epithelial tissue, it does not cause vaginal irritation or tissue damage. Moreover, the i.v. injection of the G2-S16 dendrimer did not cause a damaging effect on the studied organs and it did not modify the hemogram or the biochemical plasma markers. In conclusion, the G2-S16 dendrimer has a very good safety profile, indicating that this molecule can be a very safe and efficient vaginal microbicide.

Abstract
PURPOSE OF REVIEW This review summarizes interventions to promote HIV pre-exposure prophylaxis (PrEP) use among adolescent girls and young women (AGYW) in HIV endemic settings, while also highlighting gaps in our current measures of PrEP intervention success. RECENT FINDINGS AGYW report challenges with PrEP use, although the field is currently grappling with defining metrics of optimal PrEP use applicable for AGYW with dynamic HIV prevention needs. Ongoing studies are exploring multilevel interventions to address barriers to PrEP use for AGYW. At the individual and interpersonal levels, mHealth, drug-level feedback, adherence counseling, peer groups, and PrEP decision-support interventions are acceptable and feasible for AGYW although limited effectiveness data are available. At the health facility and community levels, PrEP demand creation, modified PrEP refill schedules, and integrated PrEP and reproductive health services are also promising options to support PrEP use for AGYW. As PrEP delivery continues to expand, improved metrics of success and evidence on the effectiveness of multi-level adherence support interventions are needed to maximize the impact of PrEP for AGYW in HIV endemic settings. We present case studies of these intervention approaches but limited data are currently available on the effectiveness of these approaches. We will look toward forthcoming study results on the impact of PrEP interventions, including mHealth, drug-level feedback and other enhanced counseling, peer support, decision-support tools, PrEP demand creation, modified refills, and integrated service delivery, to determine the ideal package of PrEP support approaches for AGYW.

Abstract
Background Pre-exposure prophylaxis (PrEP) has the potential to reduce HIV transmission and stem the HIV epidemic. Unfortunately, PrEP uptake in rural sub-Saharan Africa has been slow and medication adherence has been suboptimal. Objective To explore the perspectives, attitudes, and experiences of HIV serodiscordant partners taking PrEP and develop a messaging campaign to improve PrEP uptake in rural Mozambique to reduce HIV transmission among serodiscordant partners. Methods In this qualitative study, we interviewed 20 people in serodiscordant relationships using PrEP at a rural health center in Zambézia province, Mozambique and employed inductive and deductive coding to elicit their perspectives, attitudes, and experiences related to learning their partner’s HIV status, barriers to PrEP uptake, obstacles to PrEP adherence, and decisions to disclose their PrEP use with family and friends using thematic analysis. Results Our analysis generated nine themes across various levels of the socioecological model. Participants reported a strong desire to stay in the discordant relationship and highlighted the importance of working together to ensure PrEP and antiretroviral therapy adherence, with the majority skeptical that adherence could be achieved without both partners’ support (individual and interpersonal). Although most participants were reticent about sharing their serodiscordant status with family and friends (individual and interpersonal), those who did found their family and friends supportive (interpersonal). Participants suggested increasing community health agent availability to help people navigate HIV prevention and treatment (organizational). We then created three oral stories, using themes from the interviews, with examples from various levels of the socioecological model that will be used to generate support for PrEP use among community members. Conclusions Our findings informed oral template stories that will be used to emphasize how couples can work together to improve PrEP uptake and reduce incident HIV infections in serodiscordant couples elsewhere in rural Mozambique.

High Levels of Prevention-Effective Adherence to HIV PrEP: An Analysis of Substudy Data From the EPIC-NSW Trial. J Acquir Immune Defic Syndr 2021; 87:1040-1047.

Abstract
BACKGROUND Preexposure prophylaxis (PrEP) prevents HIV infection but relies on good adherence at times of risk, termed "prevention-effective adherence." Most studies assess adherence without reference to sexual behaviur, making it challenging to determine if poor adherence coincides with HIV risk. SETTING We examined data from a behavioral substudy of a large-scale PrEP implementation trial in New South Wales, Australia. METHODS Trial participants completed optional brief quarterly surveys, reporting the number of pills taken and sexual behavior with male partners for each day of the "last full week" before each survey. Condomless sex (CLS) was defined as "higher risk" for HIV when with HIV-positive men with detectable/unknown viral loads or unknown HIV status men. Adequate PrEP protection was defined as ≥4 pills for participants assigned male sex at birth and ≥6 pills for participants assigned female sex at birth (including transgender men). RESULTS Of 9596 participants dispensed PrEP, 4401 completed baseline and ≥1 follow-up survey. Participants reported on 12,399 "last full weeks": 7485 weeks (60.4%) involved CLS and 2521 weeks (33.7% of CLS-weeks) involved higher risk CLS. There were 103 weeks in which participants did not have adequate PrEP protection and had higher risk CLS: 4.1% of higher-risk CLS weeks (n = 103/2521), 1.4% of all CLS weeks (n = 103/7485), and 0.8% of all observed weeks (n = 103/12,399). CONCLUSIONS In a large PrEP trial, prevention-effective adherence to PrEP was very high at 99%. Our findings illustrate the importance of measuring pill-taking and sexual behavior in the same period so that prevention-effective adherence can be better estimated.

Abstract
BACKGROUND Preexposure prophylaxis (PrEP) discontinuation rates in clinical trials and demonstration projects have been well characterized; however, little is known about discontinuation in routine public health settings in sub-Saharan Africa. Understanding discontinuation in nonstudy settings is important for establishing expectations for PrEP continuation in national programs and for facilitating effective PrEP scale-up. METHODS We conducted in-depth interviews with 46 individuals who had initiated PrEP at 25 HIV comprehensive care clinics (CCCs) in central and western Kenya and whose clinic records indicated they had discontinued. RESULTS Many of our study participants discontinued PrEP when their perceived risk decreased (eg, hiatus or end of a sexual relationship or partner known to be living with HIV became virally suppressed). Others reported discontinuation due to side effects, daily pill burden, preference for condoms, or their partner's insistence. Participant narratives frequently described facility level factors such as stigma-related discomforts with accessing PrEP at CCCs, inconvenient clinic location or operating hours, long wait times, and short refill dates as discouraging factors, suggesting actionable areas for improving PrEP access and continuation. CONCLUSION Clients frequently make intentional decisions to discontinue PrEP as they weigh different prevention options within the context of complex lives. Many clients will decide to discontinue PrEP when perceiving themselves to be at reduced risk and PrEP counseling must include provisions for addressing seasons of risk. PrEP will not be the right prevention method for everyone, or forever. Expanding PrEP access points and increasing sex-positive messaging may facilitate PrEP being a better option for many.

Abstract
Pre-exposure prophylaxis (PrEP) has revolutionized HIV prevention efforts by effectively preventing the sexual transmission of HIV infection. Few studies have examined PrEP uptake and discontinuation among transgender individuals who are underserved in HIV prevention efforts. An online U.S. nationwide survey screened 294 HIV-negative transgender people for participation in a larger cohort study. We analyzed associations between demographic characteristics and PrEP use and discontinuation. We conducted thematic analyses of open-ended responses to identify reasons for PrEP discontinuation. Fifty-one participants (17.4%) reported ever receiving a PrEP prescription. Transgender men reported higher PrEP use than transgender women (χ2 = 18.06; p < 0.0001). PrEP discontinuation was reported by 49.0% of individuals who reported PrEP use. Reasons for PrEP discontinuation were related to side effects, insurance coverage, relationship status, and access to providers. HIV prevention efforts to increase PrEP should include mechanisms for PrEP uptake and re-initiation among transgender individuals.

Abstract
Supplemental Digital Content is Available in the Text. A strategy of pre-exposure prophylaxis (PrEP) transitioning to treatment as prevention is highly efficacious and cost effective for prevention of HIV transmission within HIV serodiscordant couples. We assessed whether couples who adopted this strategy experienced changes in sexual behaviors after HIV-negative partners discontinued PrEP and transitioned to rely primarily on their partner's adherence to antiretroviral therapy (ART) for prevention.

Abstract
BACKGROUND PrEP use should be aligned with periods of risk for HIV acquisition. For HIV serodiscordant couples, PrEP can be used as a bridge until the partner living with HIV takes antiretroviral therapy (ART) long enough to achieve viral suppression (the "PrEP as a Bridge to ART" strategy). However, adherence to this strategy is unknown. METHODS In a demonstration project in Kenya and Uganda, HIV-uninfected partners of serodiscordant couples were advised to take PrEP until the partner living with HIV took ART for ≥ 6 months. PrEP discontinuation was then recommended unless there were concerns about ART adherence, immediate fertility intentions, or outside partners with unknown HIV/ART status. Electronic adherence monitoring and socio-behavioral questionnaire data were used in logistic regression models to explore completion of this strategy and continuation of PrEP beyond recommendations to stop its use. RESULTS Among 833 serodiscordant couples, 436 (52%) HIV-uninfected partners completed ≥ 6 months of PrEP as a bridge to ART. Strategy completion was associated with older age (aOR per 5 years = 1.1; p = 0.008) and having fewer children (aOR = 0.9; p = 0.019). Of the 230 participants encouraged to stop PrEP according to strategy recommendations, 170 (74%) did so. PrEP continuation among the remaining 60 participants was associated with more education (aOR = 1.1; p = 0.029), a preference for PrEP over ART (aOR = 3.6; p = 0.026), comfort with managing their serodiscordant relationship (aOR = 0.6; p = 0.046), and believing PrEP makes sex safe (aOR = 0.5; p = 0.026). CONCLUSION Half of participants completed the PrEP as a bridge to ART strategy and the majority stopped PrEP as recommended. These findings suggest that targeting PrEP to periods of risk is a promising approach; however, tailoring counseling around aligning PrEP use and HIV risk will be important for optimal strategy implementation.

Abstract
Objective: The aim of this study was to appropriately plan for rollout and monitor impact of oral preexposure prophylaxis (PrEP). It is important to understand PrEP continuation and come to a consensus on how best to measure PrEP continuation. This study reviews data on PrEP continuation to document how it is reported, and to compare continuation over time and across populations. Design: A systematic review and meta-analysis. Methods: We searched MEDLINE, Embase and Global Health and reviewed abstracts from HIV conferences from 2017 to 2018 for studies reporting primary data on PrEP continuation. Findings were summarized along a PrEP cascade and continuation was presented by population at months 1, 6 and 12, with random-effects meta-analysis. Results: Of 2578 articles and 596 abstracts identified, 41 studies were eligible covering 22 034 individuals. Continuation data were measured and reported inconsistently. Results showed high discontinuation at month 1 and persistent discontinuation at later time points in many studies. Pooled continuation estimates were 66% at month 1 [n = 5348; 95% confidence interval (95% CI): 48–82], 63% at month 6 (n = 13 629; 95% CI: 48–77) and 71% at month 12 (n = 14 933; 95% CI: 60–81; higher estimate than previous timepoints due to inclusion of different studies). Adequate data were not available to reliably compare estimates across populations. Conclusion: This review found that discontinuation at one month was high, suggesting PrEP initiations may be a poor measure of effectiveness. Continuation declined further over time in many studies, indicating existing cross-sectional indicators may not be adequate to understand PrEP use patterns. Studies do not measure continuation consistently, and consensus is needed.
