RESUMEN

OBJECTIVES: DREAM-01 was an open label, dose-escalation and variable osmolarity study to identify a tenofovir HIV-prevention douche/enema that could achieve protective colon tissue cell concentrations and high acceptability. To assess impact on sexual enjoyment, iso-osmolar and hypo-osmolar placebo douches were provided for at-home use before receptive anal sex (RAS). METHODS: Eighteen HIV-uninfected men who have RAS were administered three tenofovir douches at the research clinic: Product A, an iso-osmolar dose; Product B, an iso-osmolar escalation dose; and Product C, a hypo-osmolar escalation dose. Following Products A and C, participants were given a saline douche of matching osmolarity to use at home before RAS. Participants reported acceptability via a computer-assisted self-interview and in-depth interview in this mixed-methods study. RESULTS: All three products were rated acceptable by 17 (95%) of the participants. A majority (94%) would be likely or very likely to use any of the three products before RAS. Of those who used the saline douches before RAS and then rated their sexual enjoyment, most reported that their sexual enjoyment was not affected. Interview data revealed that participants found the product easy to incorporate into their regular routine, but would prefer to use more liquid for cleansing. CONCLUSIONS: These findings indicate that the hypo-osmolar Product C, which also provides the most rapid delivery of tenofovir for HIV prevention, is acceptable for future safety trials and that our sample reports high likelihood of using a rectal microbicide douche for HIV prevention. Our findings support continued pursuit of a tenofovir rectal microbicide douche. TRIAL REGISTRATION NUMBER: NCT02750540.

RESUMEN

Pregnant and lactating persons in sub-Saharan Africa face a heightened risk of HIV acquisition, due to biological and behavioral factors, combined with limited access to prevention and treatment services. Oral pre-exposure prophylaxis (PrEP) and the dapivirine vaginal ring are promising tools for HIV prevention, and the ring's recent approval in multiple African countries represents a significant advancement in expanding access to HIV prevention. In a nested qualitative study within the MTN-042 trial, we explored the acceptability of study products among pregnant persons in the second and early third trimesters. Interviews were conducted privately, using a semi-structured guide with 77 participants, in participants' preferred language. Topics explored included product acceptability (using the theoretical framework of acceptability), user experience, satisfaction, disclosure, community attitudes, and sexual activity during pregnancy. Interview transcripts were analyzed using Dedoose software. We observed positive attitudes among participants towards the study products, which they found generally user-friendly, despite the added complexities of using them during pregnancy. Participants recognized that consistent and correct use would provide protection for both them and their unborn children. Although initial concerns existed, most of these worries dissipated over time, with study staff support and increased product use experience. These findings emphasize the importance of continued surveillance, support, and education to ensure the successful rollout of new HIV prevention measures during pregnancy.

RESUMEN

The DESIRE Study (MTN-035) explored product preference among three placebo rectal microbicide (RM) formulations, a rectal douche (RD), a suppository, and an insert, among 210 sexually active transgender people and men who have sex with men in five counties: the United States, Peru, Thailand, South Africa, and Malawi. Participants used each product prior to receptive anal sex (RAS) for 1 month, following a randomly assigned sequence, then selected their preferred product via computer assisted self-interview. In-depth interviews examined reasons for preference. We compared product preference and prior product use by country to explore whether geographic location and experience with the similar products impacted preference. A majority in the United States (56%) and Peru (58%) and nearly half in South Africa (48%) preferred the douche. Most in Malawi (59%) preferred the suppository, while half in Thailand (50%) and nearly half in South Africa (47%) preferred the insert. Participants who preferred the douche described it as quick and easy, already routinized, and serving a dual purpose of cleansing and protecting. Those who preferred the insert found it small, portable, discreet, with quick dissolution. Those who preferred the suppository found the size and shape acceptable and liked the added lubrication it provided. Experience with product use varied by country. Participants with RD experience were significantly more likely to prefer the douche (p = 0.03). Diversifying availability of multiple RM dosage forms can increase uptake and improve HIV prevention efforts globally.


RESUMEN: El estudio DESIRE (MTN-035) exploró la preferencia de producto entre tres formulaciones de microbicida rectal (MR) de placebo, una ducha rectal, un supositorio y un inserto, entre 210 personas transgénero y hombres que tienen sexo con hombres en cinco países: los Estados Unidos, Perú., Tailandia, Sudáfrica y Malawi. Los participantes utilizaron cada producto antes del sexo anal receptive (SAR) durante un mes, siguiendo una secuencia asignada al azar, luego seleccionaron su producto preferido mediante una autoentrevista asistida por computadora. Las entrevistas en profundidad examinaron los motivos de preferencia. Comparamos la preferencia de producto y el uso previo del producto por país para explorar si la ubicación geográfica y la experiencia con la forma farmacéutica impactaron la preferencia. Una mayoría en los Estados Unidos (56%) y Perú (58%) y casi la mitad en Sudáfrica (48%) prefirieron la ducha rectal. La mayoría en Malawi (59%) prefirió el supositorio, mientras que la mitad en Tailandia (50%) y casi la mitad en Sudáfrica (47%) prefirió el inserto. Los participantes que prefirieron la ducha rectal la describieron como rápida y fácil, ya parte de su rutina y que tenía el doble propósito de limpiar y proteger. Los que prefirieron el inserto lo consideraron pequeño, portátil, discreto y de rápida disolución. Los que prefirieron el supositorio encontraron que tenía un tamaño y forma aceptables y proveía lubricación adicional. La experiencia con el uso del producto varió según el país. Los participantes con experiencia con duchas rectales tenían significativamente más probabilidades de preferir la ducha rectal (p = 0,03). Diversificar la disponibilidad de múltiples formas farmacéuticas de MR puede aumentar la aceptación y mejorar los esfuerzos de prevención del VIH a nivel mundial.

RESUMEN

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.

RESUMEN

BACKGROUND: Men who have sex with men (MSM) are disproportionally affected by HIV and drug and alcohol use; however, few effective HIV prevention interventions for MSM who use substances exist. Screening, Brief Intervention, and Referral to Treatment is an early intervention for non-treatment-seeking individuals with problematic substance use and for timely referral to treatment for those with substance use disorders. Electronic screening and brief interventions (e-SBIs) reduce implementation challenges. An e-SBI tailored for MSM at the time of HIV testing might be particularly opportune to strengthen their motivation to reduce substance use and HIV risk behavior. OBJECTIVE: This study aims to develop a tailored e-SBI program to reduce substance use and HIV risk behavior among MSM seeking HIV testing at Nexo Asociación Civil, our community partners in Argentina (primary); assess the feasibility and acceptability of integrating the e-SBI into the Nexo HIV testing program (primary); assess the feasibility and acceptability of implementing an adapted Men's Health Project (MHP) at Nexo (secondary); and finally, explore preliminary findings on substance use and sexual risk reduction outcomes (exploratory). METHODS: This mixed methods study has 2 stages. During stage 1 (development), we will use the User Centered Rapid App Design process consisting of focus groups (n=16), individual interviews (n=24), and a pilot deployment of the e-SBI (n=50) to iteratively develop the e-SBI. Quantitative and qualitative assessments at each step will inform the revision of the e-SBI. Furthermore, we will use the assessment, decision, administration, production, topic experts, integration, training, testing framework to adapt MHP. During stage 2 (pilot randomized controlled trial [RCT]), we will randomize 200 MSM coming to Nexo for HIV testing. They will complete a baseline assessment and then their assigned intervention (e-SBI vs screening only) and will be followed-up for 6 months. We will also conduct in-depth interviews with up to 45 participants: 15 participants from either study condition who entered or completed MHP or other substance abuse treatment and 15 from each arm who met the criteria for MHP but did not request it. RESULTS: The study began recruitment in October 2022, and the stage-1 pilot study is near completion. Preliminary findings from stage 1 show high e-SBI acceptability. Data analysis of the stage-1 pilot is now beginning. The stage-2 pilot RCT will be launched in March 2024, with all data collection completed by May 2025. CONCLUSIONS: This study will allow us to assess the acceptability and feasibility of e-SBI implementation during HIV testing encounters. We will also build the necessary research infrastructure for a subsequent RCT to assess the efficacy of e-SBIs in reducing substance use and HIV sexual risk behavior among MSM in this setting.

RESUMEN

In Florida, 33% of new HIV infections among men and 21% of new infections among women are among those younger than 29 years of age. We describe the development of a Learning Health Care Community for youth (Y-LHCC) in Orange County, FL. Its core implementation team (iTeam) was composed of representatives from community agencies and academics, whose work was informed by data from the Florida Department of Health (FDOH) and regional research, in-depth interviews (IDIs) with agency representatives, and a pilot implementation of Tailored Motivational Interviewing (TMI) to improve service provision. IDIs revealed limited programming specifically for youth, significant structural challenges providing them with PrEP, and differences in use of evidence-based behavioral interventions to improve HIV services. FDOH provided data on new HIV infections, linkage to care, viral suppression, and PrEP coverage, however, limitations such as minimal data on PrEP referrals and use, agency level data, and inability to generate data quarterly (which would facilitate program improvement) were encountered. Thirty staff members from five agencies serving youth in Orange County participated in TMI training. About half the agency staff (n = 16) completed at least three of the four online training sessions. MI skills improved from pre- (n = 28; M = 1.96) to post TMI training (n = 11; M = 2.48, SD = 0.57); (t(37) = - 3.14, p = 0.0033). The iTeam held seven remote meetings and two in-person half-day meetings at the end of the study, during which they reassessed areas of focus for improving youth services. They also reiterated their commitment to continuing to meet beyond the study period and to engage other agencies in the newly established coalition. Findings highlight the potential of creating a Y-LHCC in Florida as well as some of the challenges that will need to be overcome to achieve ending the HIV Epidemic goals for young people in the region.


RESUMEN: En Florida, el 33% y 21% de las nuevas infecciones del VIH entre hombres y mujeres, respectivamente, fueron entre personas menores de 29 años de edad. Describimos el desarrollo de una Comunidad de Aprendizaje de Atención Médica para jóvenes (Y-LHCC) en el Condado de Orange, FL. Su equipo central de implementación (iTeam) estuvo compuesto de representantes de agencias comunitarias y académicos, cuyo trabajo se basó en datos del Departamento de Salud de Florida (FDOH) e investigaciones regionales, entrevistas en profundidad con representantes de agencias y un programa piloto de implementación de la Entrevista Motivacional a la Medida (TMI) para mejorar la prestación de servicios. Las entrevistas revelaron poca programación específica para los jóvenes, desafíos estructurales significativos para proporcionarles PrEP, y diferencias en el uso de intervenciones conductuales basadas en evidencia para mejorar los servicios de VIH. El FDOH proporcionó datos sobre nuevas infecciones por el VIH, vinculación con la atención médica, supresión viral y cobertura de PrEP. Sin embargo, se encontraron limitaciones en la data, tales como datos limitados sobre derivaciones u uso de PrEP, falta de datos a nivel de agencia, e incapacidad para generar datos trimestrales (lo que facilitaría la mejora de programas en la agencia). Treinta miembros del personal de cinco agencias que atienden a jóvenes en el Condado de Orange participaron en la capacitación de TMI. Aproximadamente la mitad del personal de la agencia (n = 16) completó al menos tres de las cuatro sesiones de capacitación remota. Las habilidades de MI mejoraron desde antes (n = 28; M = 1.96, SD = .042) hasta después del entrenamiento de TMI (n = 11; M = 2.48, SD = 0.57); (t(37) = − 3.14, p = 0.0033). El iTeam realizó siete reuniones remotas y dos reuniones en persona de medio día al final del estudio, durante las cuales reevaluaron las áreas de enfoque para mejorar los servicios para jóvenes. También reiteraron su compromiso de continuar reuniéndose más allá del período de estudio y de involucrar a otras agencias en la coalición recién establecida. Los hallazgos destacan el potencial de crear un Y-LHCC en Florida, así como algunos de los desafíos que deberán superarse para lograr los objetivos de terminar con la epidemia de VIH para los jóvenes de la región.

RESUMEN

We present experiences of transgender women (TW) who have sex with men with SMARTtest, a smartphone app to accompany the INSTI Multiplex®, a one-minute, dual blood-based HIV/syphilis rapid test. TW participants (N = 11) received 10 INSTI Multiplex® tests to take home for self- and/or partner-testing and installed the SMARTtest app on their phones. The SMARTtest app aimed to support INSTI Multiplex users in correctly performing the test, interpreting the results, and connecting with care following a positive HIV or syphilis screening. After 3 months, users completed in-depth interviews on their experiences. A total of 9 TW used SMARTtest with partners. App feedback was positive, but refining is necessary. Specifically, TW reported that SMARTtest is easy to use and convenient; instructions on how to use the INSTI Multiplex presented on the app were helpful to complete procedures correctly; the most frequently used feature on SMARTtest was the information on clinics that offered confirmatory testing; and participants and their partners were not concerned about app privacy but reported that this could change if INSTI Multiplex detected an HIV-positive result. Further, participants provided recommendations on how to improve SMARTtest, and changes were mostly related to features, content, functionality, navigation, and overall "look" of the app. SMARTtest is promising to facilitate INSTI Multiplex® use in TW. User feedback should be integrated in future versions.

RESUMEN

OBJECTIVES: After identifying and recruiting men who have sex with men living with HIV and virally unsuppressed, this study attempted to enhance treatment and care via case management to increase the proportion who achieved viral suppression. DESIGN: Participants were randomized into one of two study arms: standard of care (SOC) or enhanced case management (CM) intervention. Participants were followed for 12 months with quarterly study assessments, with blood collected for CD4+ cell count testing, HIV viral load testing (primary prespecified outcome), and plasma storage. METHODS: Participants identified via respondent-driven sampling and direct recruitment and were invited to participate in the randomized controlled trial. The CM intervention provided a wide range of support services including, health education, clinical care coordination, medication adherence support, and social service assistance. The month-12 assessment included questions about healthcare utilization, stigma, substance use, and mental health. RESULTS: Among the 144 participants virally unsuppressed at baseline, most had had a previous positive HIV test result; were Black, non-Hispanic, gay and bisexual men, aged 22-50. Among the 128 participants at the last study visit, 68 were virally suppressed, with no statistically significant difference between the CM and SOC arms (viral suppression 42% and 53%, respectively; adjusted odds ratio = 0.62 [P = 0.15; 95% confidence interval: 0.32, 1.2]). CONCLUSIONS: Reaching targets of at least 90% sustained viral suppression among all people with HIV will likely require more than an individual-level CM approach that addresses barriers to optimal care and treatment at multiple levels.

RESUMEN

One-quarter of gay, bisexual, and other men who have sex with men (GBMSM) with diagnosed HIV are not engaged in HIV care. Between 2018 and 2019, 50 GBMSM completed qualitative interviews 3 months after receiving an HIV-positive result. Interviews explored barriers to and facilitators of engagement and retention in HIV testing and care. Thematic analysis revealed five major themes: (1) reason for HIV testing (e.g., self-testing), (2) linkage to care (e.g., appointment/logistic issues and social support as encouragement), (3) barriers to engagement in care (e.g., financial burden, competing priorities, and fear/stigma), (4) facilitators of engagement (e.g., financial assistance, patient-provider relationships, auxiliary support services, and health agency), and (5) PrEP as a missed prevention opportunity. Addressing individual-, social-, and policy-level barriers could improve GBMSM's engagement in HIV care. Further, capitalizing on GBMSM's health agency through partnerships with local agencies and fostering better patient-provider relationships could optimize HIV care continuity.

RESUMEN

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.
