BACKGROUND: Peer-delivered HIV self-testing (HIVST) and sexually transmitted infection self-sampling (STISS) may promote adherence to oral pre-exposure prophylaxis (PrEP), but no studies have analyzed this approach among transgender women (TGW) in sub-Saharan Africa.
METHODS: The Peer study was a cluster randomized trial in Uganda (October 2020-July 2022; NCT04328025).
METHODS: Ten TGW peer groups, each with 1 TGW peer and 8 TGW, were randomized 1:1 to receive quarterly in-clinic HIV testing with PrEP refills as standard-of-care (SOC) or SOC plus monthly peer delivery of oral-fluid HIVST, STISS, and PrEP refills (intervention). Participants were followed for 12 months. The primary outcome was PrEP adherence.
RESULTS: We screened 85 TGW and enrolled 82 (41 per arm). The median age was 22 years (interquartile range [IQR] 20-24). Twelve-month retention was 88% (72/82). At the 3, 6, 9, and 12-month clinic visits, 10%, 5%, 5%, and 0% of TGW in the intervention arm had TFV-DP levels ≥700 fmol/punch, versus 7%, 15%, 7%, and 2% in the SOC arm, respectively (P = 0.18). At all visits, any detectable TFV-DP levels were significantly higher in SOC than the peer delivery group (P < 0.04). PrEP adherence was associated with sex work (incidence rate ratio 6.93; 95% CI: 2.33 to 20.60) and >10 years of schooling (incidence rate ratio 2.35; 95% CI: 1.14 to 4.84). There was a strong correlation between tenofovir detection in dried blood spots and urine (P < 0.001). No HIV seroconversions occurred.
CONCLUSIONS: Peer-delivered HIVST and STISS did not increase low levels of oral PrEP adherence among TGW in Uganda. Long-acting PrEP formulations should be considered for this population.

BACKGROUND: Gay, bisexual, and other men who have sex with men living with HIV (GBMSM-LWH) in the United States bear a heavy burden of bacterial sexually transmitted infections (STIs). Timely diagnosis and treatment are key to prevention. Only a few studies have combined home specimen self-collection for bacterial STI screening with live audio and video (AV) conferencing. None have focused on GBMSM-LWH or incorporated motivational interviewing (MI), a client-centered, strengths-based counseling approach that seeks to support individuals to create positive behavioral change.
OBJECTIVE: Our study seeks to investigate the feasibility and acceptability of an MI-based telehealth intervention that integrates home specimen self-collection from different anatomical sites of possible exposure and MI delivered via live AV conferencing to engage sexually active GBMSM-LWH in bacterial STI screening.
METHODS: Participants are being recruited from across the United States via advertising on mobile dating apps and social networking sites and via peer referral. Phase 1 involves piloting the delivery of an innovative telehealth intervention for bacterial STI screening to 75 GBMSM-LWH. Our intervention includes three components: (1) a pretest live AV conferencing session involving an MI-guided discussion to elicit awareness of bacterial STIs; fill any knowledge gaps; bolster the perceived importance of regularly testing for gonorrhea, chlamydia, and syphilis; and build self-efficacy for specimen self-collection; (2) home self-collection and return via mail of a urine sample (for gonorrhea and chlamydia testing), a throat swab (for gonorrhea and chlamydia testing), a rectal swab (for gonorrhea and chlamydia testing), and a finger-stick blood sample (for syphilis testing); and (3) a posttest live AV conferencing session involving an MI-guided discussion to prepare participants for receiving test results and formulate personalized action plans for seeking treatment (if warranted) and repeat testing. Descriptive statistics and progression ratios will be calculated, and potential variations in our intervention\'s feasibility and acceptability will be numerically summarized and graphically visualized. Phase 2 involves elucidating attitudes, facilitators, and barriers related to engaging in each intervention component via semistructured in-depth interviews with a purposive subsample of 20 participants who complete progressively smaller subsets of the pretest session, specimen return for bacterial STI testing, and the posttest session. Thematic analysis will be used to identify, analyze, and report patterns in the data. Quantitative and qualitative data will be integrated at the design, methods, interpretation, and reporting levels.
RESULTS: Study procedures were approved by the Institutional Review Board at the University of Michigan in September 2023. Participant recruitment began in April 2024.
CONCLUSIONS: Our study will advance multiple goals of the STI National Strategic Plan for the United States for 2021 to 2025, specifically those pertaining to preventing new STIs; accelerating progress in STI research, technology, and innovation; and reducing STI-related health disparities.

HIV self-testing (HIVST) has the potential to reduce barriers associated with clinic-based preexposure prophylaxis (PrEP) delivery. We conducted a substudy nested in a prospective, pilot implementation study evaluating patient-centered differentiated care services. Clients chose either a blood-based or oral fluid HIVST kit at the first refill visit. Data were abstracted from program files and surveys were administered to clients. We purposively sampled a subset of PrEP clients and their providers to participate in in-depth interviews. We surveyed (n = 285). A majority (269/285, 94%) reported HIV risk. Blood-based HIVST was perceived as easy to use (76/140, 54%), and (41/140, 29%) perceived it to be more accurate. Oral fluid-based HIVST was perceived to be easy to use (95/107, 89%), but almost all (106/107, 99%) perceived it as less accurate. HIVST improved privacy, reduced workload, and saved time. HIVST demonstrates the potential to streamline facility-based PrEP care in busy African public health facilities.

BACKGROUND: Chlamydia remains prevalent worldwide and is considered a global public health problem. However, testing rates among young sexually active people remain low. Effective clinical management relies on screening asymptomatic patients. However, attending face-to-face consultations of testing for sexually transmitted infections is associated with stigmatization and anxiety. Self-testing technology (STT) allows patients to test themselves for chlamydia and gonorrhea without the presence of health care professionals. This may result in wider access to testing and increase testing uptake. Therefore, the sexual health clinic at Odense University Hospital has designed and developed a technology that allows patients to get tested at the clinic through self-collected sampling without a face-to-face consultation.
OBJECTIVE: This study aimed to (1) pilot-test STT used in clinical practice and (2) investigate the experiences of patients who have completed a self-test for chlamydia and gonorrhea.
METHODS: The study was conducted as a qualitative study inspired by the methodology of participatory design. Ethnographic methods were applied in the feasibility study and the data analyzed were inspired by the action research spiral in iterative processes using steps, such as plan, act, observe, and reflect. The qualitative evaluation study used semistructured interviews and data were analyzed using a qualitative 3-level analytical model.
RESULTS: The findings from the feasibility study, such as lack of signposting and adequate information, led to the final modifications of the self-test technology and made it possible to implement it in clinical practice. The qualitative evaluation study found that self-testing was seen as more appealing than testing at a face-to-face consultation because it was an easy solution that both saved time and allowed for the freedom to plan the visit independently. Security was experienced when the instructions balanced between being detail-oriented while also being simple and illustrative. The anonymity and discretion contributed to preserving privacy and removed the fear of an awkward conversation or being judged by health care professionals thus leading to the reduction of intrusive feelings.
CONCLUSIONS: Accessible health care services are crucial in preventing and reducing the impact of sexually transmitted infections and STT may have the potential to increase testing uptake as it takes into account some of the barriers that exist. The pilot test and evaluation have resulted in a fully functioning implementation of STT in clinical practice.

UNASSIGNED: This pilot study aimed to assess the feasibility, accuracy, and repeatability of unsupervised, at-home, multi-day glaucoma testing using the Olleyes VisuALL Virtual Reality Platform (VRP) and the iCare HOME handheld self-tonometer.
UNASSIGNED: Participants were trained to use two U.S. Food and Drug Administration-registered or approved devices before conducting self-tests at home over 3 consecutive days. The iCare HOME intraocular pressure (IOP) measurements were collected four times daily per eye, and VRP visual field tests were performed once daily. The results were compared with one in-clinic Humphrey Field Analyzer (HFA) visual field test performed on the day of device training, iCare HOME measurements by the trainer, and the last five Goldmann applanation tonometer (GAT) results.
UNASSIGNED: Of 15 enrolled participants, nine of them (60%) completed the study. The six excluded participants could not self-measure using iCare HOME. There was significant correlation between the average mean deviation (MD) values of the at-home VRP tests and in-clinic HFA test (r2 = 0.8793, P < 0.001). Additionally, the average of the sensitivities in five of six Garway-Heath sectors were significantly correlated. VRP test duration was also shorter than in-clinic HFA testing (P < 0.001). Finally, at-home tonometry yielded statistically similar values compared to trainer-obtained iCare HOME values. The mean and range of at-home tonometry were also statistically similar to those for in-clinic GAT, but at-home tonometry demonstrated higher maximum IOP values (P = 0.0429).
UNASSIGNED: Unsupervised, at-home, multi-day glaucoma testing using two devices resulted in the capture of higher maximum IOPs than in the clinic and good MD correlation of VRP with HFA. However, 40% of participants could not self-measure IOP using iCare HOME.
UNASSIGNED: The study findings suggest that at-home remote glaucoma monitoring correlates with in-office testing and could provide additional information for glaucoma management, although patients had more difficulty with the iCare HOME than the VRP.

BACKGROUND: Early identification of an acute respiratory infection is important for reducing transmission and enabling earlier therapeutic intervention. We aimed to prospectively evaluate the feasibility of home-based diagnostic self-testing of viral pathogens in individuals prompted to do so on the basis of self-reported symptoms or individual changes in physiological parameters detected via a wearable sensor.
METHODS: DETECT-AHEAD was a prospective, decentralised, randomised controlled trial carried out in a subpopulation of an existing cohort (DETECT) of individuals enrolled in a digital-only observational study in the USA. Participants aged 18 years or older were randomly assigned (1:1:1) with a block randomisation scheme stratified by under-represented in biomedical research status. All participants were offered a wearable sensor (Fitbit Sense smartwatch). Participants in groups 1 and 2 received an at-home self-test kit (Alveo be.well) for two acute respiratory viral pathogens: SARS-CoV-2 and respiratory syncytial virus. Participants in group 1 could be alerted through the DETECT study app to take the at-home test on the basis of changes in their physiological data (as detected by our algorithm) or due to self-reported symptoms; those in group 2 were prompted via the app to self-test only due to symptoms. Group 3 served as the control group, without alerts or home testing capability. The primary endpoints, assessed on an intention-to-treat basis, were the number of acute respiratory infections presented (self-reported) and diagnosed (electronic health record), and the number of participants using at-home testing in groups 1 and 2. This trial is registered with ClinicalTrials.gov, NCT04336020.
RESULTS: Between Sept 28 and Dec 30, 2021, 450 participants were recruited and randomly assigned to group 1 (n=149), group 2 (n=151), or group 3 (n=150). 179 (40%) participants were male, 264 (59%) were female, and seven (2%) identified as other. 232 (52%) were from populations historically under-represented in biomedical research. 118 (39%) of the 300 participants in groups 1 and 2 were prompted to self-test, with 61 (52%) successfully completing self-testing. Participants were prompted to home-test more frequently due to symptoms (41 [28%] in group 1 and 51 [34%] in group 2) than due to detected physiological changes (26 [17%] in group 1). Significantly more participants in group 1 received alerts to test than did those in group 2 (67 [45%] vs 51 [34%]; p=0·047). Of the 61 individuals who were prompted to test and successfully did so, 19 (31%) tested positive for a viral pathogen-all for SARS-CoV-2. The individuals diagnosed as positive for SARS-CoV-2 in the electronic health record were eight (5%) in group 1, four (3%) in group 2, and two (1%) in group 3, but it was difficult to confirm if they were tied to symptomatic episodes documented in the trial. There were no adverse events.
CONCLUSIONS: In this direct-to-participant trial, we showed early feasibility of a decentralised programme to prompt individuals to use a viral pathogen diagnostic test based on symptoms tracked in the study app or physiological changes detected using a wearable sensor. Barriers to adequate participation and performance were also identified, which would need to be addressed before large-scale implementation.

BACKGROUND: Past research shows that HIV self-testing (HIVST) can increase testing and facilitate more HIV diagnoses relative to clinic testing. However, in the United States, the use of HIVSTs is limited due to concerns that those who use HIVST could be less likely to be linked to care.
METHODS: From January 2019 to April 2022, we recruited 811 men who have sex with men (MSM) in the United States who tested infrequently using an online marketing campaign and randomized them 1:1:1 to receive one of the following every 3 months for a year: (1) text message reminders to get tested at a local clinic (control); (2) mailed HIVST kits with access to a free helpline (standard HIVST); and (3) mailed HIVST kits with counselling provided within 24 hours of opening a kit (eTest). Quarterly follow-up surveys assessed HIV testing, sexually transmitted infection (STI) testing, pre-exposure prophylaxis (PrEP) use and sexual risk behaviour.
RESULTS: Eight participants were diagnosed with HIV, and all but one were through HIVST. Participants in either HIVST condition, standard or eTest, had significantly higher odds of any testing (OR = 7.9, 95% CI = 4.9-12.9 and OR = 6.6, 95% CI = 4.2-10.5) and repeat testing (>1 test; OR = 8.5, 95% CI = 5.7-12.6; OR = 8.9, 95% CI = 6.1-13.4) over 12 months relative to the control group. Rates of STI testing and PrEP uptake did not differ across study condition, but those in the eTest condition reported 27% fewer sexual risk events across the study period relative to other groups.
CONCLUSIONS: HIVST vastly increased testing, encouraged more regular testing among MSM, and identified nearly all new cases, suggesting that HIVST could diagnose HIV acquisition earlier. Providing timely follow-up counselling after HIVST did not increase rates of STI testing or PrEP use, but some evidence suggested that counselling may have reduced sexual risk behaviour. To encourage more optimal testing, programmes should incorporate HIVST and ship kits directly to recipients at regular intervals.

BACKGROUND: Assisted partner services (APS) is an effective strategy for increasing HIV testing, new diagnosis, and linkage to care among sexual partners of people living with HIV (PLWH). APS can be resource intensive as it requires community tracing to locate each partner named and offer them testing. There is limited evidence for the effectiveness of offering HIV self-testing (HIVST) as an option for partner testing within APS.
METHODS: We conducted a cluster randomized controlled trial comparing provider-delivered HIV testing (Standard APS) versus offering partners the option of provider-delivered testing or HIVST (APS+HIVST) at 24 health facilities in Western Kenya. Facilities were randomized 1:1 and we conducted intent-to-treat analyses using Poisson generalized linear mixed models to estimate intervention impact on HIV testing, new HIV diagnoses, and linkage to care. All models accounted for clustering at the clinic level and new diagnoses and linkage models were adjusted for individual-level age, sex, and income a priori.
RESULTS: From March to December 2021, 755 index clients received APS and named 5054 unique partners. Among these, 1408 partners reporting a prior HIV diagnosis were not eligible for HIV testing and were excluded from analyses. Of the remaining 3646 partners, 96.9% were successfully contacted for APS and tested for HIV: 2111 (97.9%) of 2157 in the APS+HIVST arm and 1422 (95.5%) of 1489 in the Standard APS arm. In the APS+HIVST arm, 84.6% (1785/2111) tested via HIVST and 15.4% (326/2111) received provider-delivered testing. Overall, 16.7% of the 3533 who tested were newly diagnosed with HIV (APS+HIVST = 357/2111 [16.9%]; Standard APS = 232/1422 [16.3%]). Of the 589 partners who were newly diagnosed, 90.7% were linked to care (APS+HIVST = 309/357 [86.6%]; Standard APS = 225/232 [97.0%]). There were no significant differences between the two arms in HIV testing (relative risk [RR]: 1.02, 95% CI: 0.96-1.10), new HIV diagnoses (adjusted RR [aRR]: 1.03, 95% CI: 0.76-1.39) or linkage to care (aRR: 0.88, 95% CI: 0.74-1.06).
CONCLUSIONS: There were no differences between APS+HIVST and Standard APS, demonstrating that integrating HIVST into APS continues to be an effective strategy for identifying PLWH by successfully reaching and HIV testing >95% of elicited partners, newly diagnosing with HIV one in six of those tested, >90% of whom were linked to care.

BACKGROUND: Persistent infection with high-risk human papillomavirus (HPV) is the causal agent of several cancers including cervical, anal and oropharyngeal cancer. Transgender men and transmasculine non-binary (TMNB) people with a cervix are much less likely to undergo cervical cancer screening than cisgender women. Transgender women and transfeminine non-binary (TWNB) people assigned male at birth may be at increased risk of HPV. Both TMNB and TWNB people face many barriers to HPV testing including medical mistrust due to stigma and discrimination.
METHODS: The Self-TI Study (Self-TI) is a pilot study designed to measure acceptability and feasibility of HPV self-testing among transgender and non-binary people in England. TMNB people aged 25-65 years, with at least 1 year of testosterone, and TWNB people, aged 18 years and over, are eligible to participate. Participants self-collect up to four samples: an oral rinse, a first void urine sample, a vaginal swab (if applicable) and an anal swab. TMNB participants are asked to have an additional clinician-collected cervical swab taken following their routine Cervical Screening Programme sample. TWNB people are asked to take a self-collection kit to perform additional self-collection at home and mail the samples back to the clinic. Acceptability is assessed by a self-administered online survey and feasibility is measured as the proportion of samples returned in the clinic and from home.
BACKGROUND: Self-TI received ethical approval from the Research Ethics Committee of Wales 4 and ethical review panel within the Division of Cancer Epidemiology and Genetics at the US National Cancer Institute. Self-TI was coproduced by members of the transgender and non-binary community, who served as authors, collaborators and members of the patient and public involvement (PPI) group. Results of this study will be shared with the community prior to being published in peer-reviewed journals and the PPI group will help to design the results dissemination strategy. The evidence generated from this pilot study could be used to inform a larger, international study of HPV self-testing in the transgender and non-binary community.

BACKGROUND: The SARS-CoV-2 pandemic presented a challenge for caregiving relatives in the home care setting. Caregivers can transmit SARS-CoV-2 to their relatives who are often at high risk for a severe course of COVID-19. Regular testing of asymptomatic caregivers for SARS-CoV-2 may reduce the risk of transmission. The optimal method and frequency of regular asymptomatic testing is unknown. We conducted a prospective, randomised trial to assess the feasibility, recruitment and acceptance of different testing frequencies. This serves to inform a future definitive randomised controlled trial.
METHODS: We carried out a parallel three-armed feasibility trial, enrolling adult participants who provided home-based care for a relative at least twice a week. Participants were randomly assigned using sealed envelopes to either conduct saliva-based antigen self-testing at a frequency of once a week (group I), twice a week (group II), or every two days (group III). The participants completed questionnaires on a weekly basis. Main outcome measures were feasibility of recruitment, adherence to self-tests and distress caused by self-testing. We further collected data on the use of mouth-nose mask.
RESULTS: From 25 March to 7 May 2021 we assessed 27 participants and randomised 26 in the study: 8 participants in group I, 8 in group II and 10 in group III. All participants completed the study. In group I 48/48 (100.0%; 95% CI 92.6% to 100.0%), in group II 93/96 (96.9%; 95% CI 91.2% to 98.9%) and in group III 209/210 (99.5%; 95% CI 97.4% to 99.9%) self-tests were carried out at home. Participants did not perceive regular self-testing as burdensome in any of the study arms. We did not observe any infection with SARS-CoV-2. During the study, mask adherence decreased from 35% to 19% in all groups.
CONCLUSIONS: Conducting such a study was feasible. The participants tolerated regular self-testing well, which was reflected in a high level of test adherence. However, regular self-testing may have led to decreased protective behaviour. To demonstrate that regular asymptomatic testing reduces infection transmission, a future definitive trial should be performed at a time of a high prevalence of SARS-CoV-2 and be implemented as a multicentre study.
BACKGROUND: The trial is registered with the German Clinical Trials Register, DRKS00026234.
