IntroductionHIV pre-exposure prophylaxis (PrEP) is an essential prevention strategy being scaled up for priority populations in Kenya, including for HIV serodiscordant couples. The COVID-19 pandemic posed challenges to PrEP rollout. We conducted a qualitative study of PrEP providers to understand how clinics adjusted PrEP delivery during the COVID-19 pandemic.MethodsSince 2017, the Partners Scale-Up Project has integrated PrEP into 25 HIV clinics in Central and Western Kenya. We conducted qualitative interviews with 40 purposively sampled clinic personnel. We interviewed personnel once during the first pandemic wave (May-Aug 2020) and again after some decline in COVID-19 rates (Nov-Jan 2021). We analysed data using inductive memo-writing and summarized data by themes along the PrEP delivery cascade, guided by the Framework for Reporting Adaptation and Modifications (FRAME).ResultsWe interviewed 27 clinical officers, five nurses, four health records and information officers, and four counsellors from Central (n = 20) and Western (n = 20) Kenya. About half (n = 19) were female, with a median age of 32 (IQR: 29-34) and 2.3 years of experience delivering PrEP (IQR: 2-3). All participants reported clinic changes in PrEP demand creation and service delivery during the pandemic. Modifications occurred during PrEP implementation and sustainment phases, were partly reactive to the pandemic and also facilitated by interim Ministry of Health guidance on PrEP delivery during COVID, and were made by PrEP delivery teams, clients and clinic managers. Commonly reported modifications included dispensing multiple-month PrEP refills, intensifying phone-based client engagement and collaborating with other HIV clinics to ensure that clients with prolonged stays in other regions could continue to access PrEP. Some clinics also adopted practices to streamline visits, such as within clinical-room PrEP dispensing, pre-packing PrEP and task-shifting. Most providers liked these changes and hoped they would continue after the pandemic subsides.ConclusionsCOVID-19 served as a catalyst for PrEP delivery innovations in Kenya. HIV clinics successfully and rapidly adapted their PrEP demand creation, refill and retention strategies to promote PrEP uptake and effective use. These modified implementation strategies highlight opportunities to streamline the delivery of PrEP, as well as other HIV and chronic care services, and strengthen engagement with populations post-pandemic.

: Introduction: Delivery of oral pre‐exposure prophylaxis (PrEP) is being scaled up in Africa, but clinic‐level barriers including lengthy clinic visits may threaten client continuation on PrEP. Methods: Between January 2020 and January 2022, we conducted a quasi‐experimental evaluation of differentiated direct‐to‐pharmacy PrEP refill visits at four public health HIV clinics in Kenya. Two clinics implemented the intervention package, which included direct‐to‐pharmacy for PrEP refill, client HIV self‐testing (HIVST), client navigator, and pharmacist‐led rapid risk assessment and dispensing. Two other clinics with comparable size and client volume served as contemporaneous controls with the usual clinic flow. PrEP continuation was evaluated by visit attendance and pharmacy refill records, and time and motion studies were conducted to determine time spent in the clinics. Dried blood spots were collected to test for tenofovir‐diphosphate (TFV‐DP) at random visits. We used logistic regression to assess the intervention effect on PrEP continuation and the Wilcoxon rank sum test to assess the effect on clinic time. Results: Overall, 746 clients were enrolled, 366 at control clinics (76 during pre‐implementation and 290 during implementation phase), and 380 at direct‐to‐pharmacy clinics (116 during pre‐implementation and 264 during implementation phase). Prior to implementation, the intervention and control clinics were comparable on client characteristics (female: 51% vs. 47%; median age: 33 vs. 33 years) and PrEP continuation (35% vs. 37% at 1 month, and 37% vs. 39% at 3 months). The intervention reduced total time spent at the clinic by 35% (median of 51 minutes at control vs. 33 minutes at intervention clinics; p Conclusions: A client‐centred PrEP delivery approach with direct‐to‐pharmacy PrEP refill visits plus client HIVST significantly reduced clinic visit time by more than one‐third and improved PrEP continuation in public health HIV clinics in Kenya., INTRODUCTION Oral pre‐exposure prophylaxis (PrEP) is a highly effective HIV prevention strategy [1–3]; however, maximizing access and continuation is a key challenge for optimizing the overall public health impact of [...]

: Introduction: Effective PrEP use is critical for impact, but data are limited on common patterns of continuation and coverage among persons using PrEP in real‐world settings. Methods: Data are from the Partners Scale‐Up Project, a programmatic stepped‐wedge cluster‐randomized trial to integrate PrEP delivery in 25 Kenyan public health facilities conducted between February 2017 and December 2021. We evaluated PrEP continuation using visit attendance and pharmacy refill records, and computed medication possession ratio to define coverage during the first year of use. Latent class mixture models were used to identify and characterize membership to different PrEP continuation patterns. Multinomial logistic regression was used to examine the association between group trajectories and demographic and behaviour characteristics. Results: Overall, 4898 persons initiated PrEP, 54% (2640) were female, mean age was 33 years (standard deviation 11) and 84% (4092) had partners living with HIV. PrEP continuation was 57%, 44%, and 34% at 1, 3, and 6 months, respectively. Four unique trajectories of PrEP coverage were identified: (1) one‐fourth (1154) exhibited consistent high coverage throughout the year with 93%, 94%, 96%, and 67% continuing PrEP at months 1, 3, 6, and 12, respectively; (2) 13% (682) showed high coverage trajectory throughout 6 months but coverage rapidly declined thereafter (94%, 93%, 63%, and 10% continued at months 1, 3, 6, and 12, respectively); (3) 18.9% (918) exhibited moderate coverage trajectory with 91% of clients refilling PrEP at month 1 but nearly all dropped‐off thereafter (37%, 5%, and 4% continued at months 3, 6, and 12, respectively); and (4) 43.8% (2144) exhibited immediate discontinuation trajectory, in which nearly all did not have any subsequent PrEP refill. Overall, being female, older age, having partners living with HIV or of unknown HIV status were statistically associated with better PrEP continuation trajectories compared to the immediate discontinuation trajectory (p Conclusions: In this analysis of a real‐world PrEP implementation programme in Kenya, we found four distinct patterns of PrEP continuation, with one‐third of users exhibiting consistent high continuation throughout 12 months and two‐fifths with immediate discontinuation patterns. These data may help guide tailored interventions to support PrEP continuation in this setting., INTRODUCTION Oral pre‐exposure prophylaxis is a highly effective HIV prevention strategy for men and women when taken with its effectiveness highly dependent on adherence [1–3]. Indeed, across first‐generation clinical PrEP [...]

Introduction: In public clinics in Kenya, separate, sequential delivery of the component services of pre-exposure prophylaxis (PrEP) (e.g. HIV testing, counselling, and dispensing) creates long wait times that hinder clients' ability and desire to access and continue PrEP. We conducted a mixed methods study in four public clinics in western Kenya to identify strategies for operationalizing a one-stop shop (OSS) model and evaluate whether this model could improve client wait time and care accept-ability among clients and providers without negatively impacting uptake or continuation. Methods: From January 2020 through November 2020, we collected and analysed 47 time-and-motion observations using Mann-Whitney U tests, 29 provider and client interviews, 68 technical assistance reports, and clinic flow maps from inter-vention clinics. We used controlled interrupted time series (cITS) to compare trends in PrEP initiation and on-time returns from a 12-month pre-intervention period (January-December 2019) to an 8-month post-period (January-November 2020, excluding a 3-month COVID-19 wash-out period) at intervention and controlclinics. Results: From the pre- to post-period, median client wait time at intervention clinics dropped significantly from 31 to 6 minutes (p = 0.02), while median provider contact time remained around 23 minutes (p = 0.4). Intervention clinics achieved efficiency gains by moving PrEP delivery to lower volume departments, moving steps closer together (e.g. relocating supplies; cross-training and task-shifting), and differentiating clients based on the subset of services needed. Clients and providers found the OSS model highly acceptable and additionally identified increased privacy, reduced stigma, and higher quality client-provider interactions as benefits of the model. From the pre- to post-period, average monthly initiations at intervention and control clinics increased by 6 and 2.3, respectively, and percent of expected follow-up visits occurring on time decreased by 18% and 26%, respectively; cITS analysis of PrEP initiations (n = 1227) and follow-up visits (n = 2696) revealed no significant difference between intervention and control clinics in terms of trends in PrEP initiation and on-time returns (all p>0.05). Conclusions: An OSS model significantly improved client wait time and care acceptability without negatively impacting initiations or continuations, thus highlighting opportunities to improve the efficiency of PrEP delivery efficiency and client-centredness.

Introduction: In Africa, oral pre-exposure prophylaxis (PrEP) is largely provided via over-burdened public HIV care clinics. Successfully incorporating PrEP services into these clinics may require adaptations to practices outlined in national implementation guidelines and modifications to routine existing service delivery. We aimed to describe adaptations made by public HIV clinics in Kenya to integrate PrEP delivery into existing services. Methods: The Partners Scale-Up Project aimed to catalyse integration of PrEP in 25 public HIV care clinics. Between May and December 2018, we conducted qualitative interviews with health providers and documented clinic observations in technical assistance (TA) reports to understand the process of PrEP service integration. We analysed 36 health provider interview transcripts and 25 TA reports to identify clinic-level adaptations to activities outlined in Kenyan Ministry of Health PrEP guidelines and modifications made to existing service delivery practices to successfully incorporate PrEP services. Identified adaptations were reported using the expanded framework for reporting adaptations and modifications (FRAME). Results: Allclinics (n = 25) performed HIV testing, HIV risk assessment, PrEP education and adherence counselling as stipulated in the guidelines. Most clinics initiated clients on PrEP without creatinine testing if otherwise healthy. While monthly refill appointments are recommended, a majority of clinics issued PrEP users two to three months of pills at a time. Clinics also implemented practices that had not been specified in the guidelines including incorporating PrEP-related topics into routine health talks, calling clients with missed PrEP appointments, discussing PrEP service delivery in regular staff meetings, 'fast-tracking' PrEP clients and dispensing PrEP in clinic rooms rather than at clinic-based pharmacies. PrEP initiation numbers were highest among clinics that did not require creatinine testing, conducted peer on-the-job PrEP training and those that discussed PrEP delivery in their routine meetings. Above-average continuation was observed among clinics that discussed PrEP in their routine meetings, dispensed PrEP in clinic rooms and offered PrEP at nonregular hours. Conclusions: Health providers in public HIV care clinics instituted practices and made innovative adaptations to PrEP delivery to reduce barriers for clients and staff. Encouraging clinic level adaptations to national implementation guidelines will facilitate scale-up of PrEP delivery.

Introduction: Sustained HIV viral suppression resulting from antiretroviral therapy (ART) eliminates the risk of HIV transmission, a concept popularly framed as Undetectable = Untransmittable (U = U). We explored knowledge and acceptance of information around the elimination of HIV transmission risk with ART (U = U) in Kenya. Methods: Our qualitative study was conducted within a project evaluating the use of pre-exposure prophylaxis (PrEP) integrated into ART care for HIV serodiscordant couples in public clinics in Kenya (the Partners Scale Up Project). From February 2017 to April 2019, we conducted semi-structured key informant interviews with 83 health providers and in-depth interviews with 61 HIV-negative people in serodiscordant relationships receiving PrEP services. Transcripts were coded using thematic analysis. Results: Health providers reported being aware of reduced risk of HIV transmission as a result of consistent ART use and used words such as 'very low,' 'minimal' and 'like zero' to describe HIV transmission risk after viral suppression. Providers reported finding viral load results helpful when counselling clients about the risk of HIV transmission. Many lacked confidence in U = U and counselled on consistent condom use even after viral suppression while some expressed concerns that communicating this message to people living with HIV (PLHIV) would lead them to engage in multiple sexual relationships. Other providers reported that they did not counsel about the reduced risk of HIV transmission after viral suppression for fear of being blamed if HIV transmission occurred. HIV-negative partners reported being informed about U = U by providers but they did not believe nor trust the message. Even after their partners achieved viral suppression, some HIV-negative partners were unwilling to stop PrEP, while others indicated that they would use condoms if they stopped PrEP to be sure that they were protected from HIV. Conclusions: Despite awareness that effective ART use eliminates HIV transmission risk, there is both a lack of in-depth knowledge and conviction about the strategy among health providers and HIV-negative partners in serodiscordant relationships. New strategies that go beyond communicating the science of U = U to consider the local social and clinical environments could maximize the effectiveness of U = U.

Background: Oral pre-exposure prophylaxis (PrEP) using co-formulated emtricitabine (FTC) and tenofovir disoproxil fumarate (TDF) is a potent HIV prevention method for men and women, with its efficacy highly dependent on adherence. A pivotal HIV efficacy study combined with a directly observed pharmacological study defined the thresholds for HIV protection in men who have sex with men (MSM), which are the keys to PrEP promotion and development of new PrEP agents. For African women at risk for HIV and belonging to a priority group considered due to disproportionately high incident HIV infections, the variable adherence in PrEP clinical trials and the limited pharmacologic data have resulted in a lack of clarity about the PrEP adherence required for HIV protection. We propose a study to quantify the adherence–concentration–efficacy thresholds of TDF/FTC PrEP among African cisgender women to inform decisions about optimal PrEP dosing and adherence for HIV protection. Methods: We randomized 45 low-risk HIV-uninfected African women, aged 18–30 years old, to directly observe the TDF/FTC PrEP of two, four, or seven doses per week for 8 weeks. A complementary age-matched pregnant women cohort at high risk of HIV, who will receive seven doses per week, was recruited (N = 15) with the primary aim of establishing benchmark concentrations in dried blood spots and peripheral blood mononuclear cells. Plasma, whole blood (WB), urine, hair, vaginal fluid, and vaginal tissue (non-pregnant women only) were archived for future testing. Drug concentrations were measured using methods validated for each biological matrix. Pharmacokinetic models were fitted to drug concentrations to quantify concentration–adherence thresholds. To define the drug concentrations associated with HIV protection, we applied the newly defined thresholds from the primary pharmacologic trial to the subset of women randomized to TDF/FTC or TDF in the Partners PrEP Study with the drug concentration assessed in plasma and WB samples. Multiple imputation was used to construct a data set with drug concentrations at each visit when an HIV test was performed for the entire cohort, replicating the work for MSM. Discussion: The proposed study generated the first African women-specific TDF– PrEP adherence–concentration–efficacy thresholds essential for guiding the accurate interpretation of TDF/FTC PrEP programs and clinical trials of novel HIV prevention products using TDF/FTC as an active control.

Background Young women account for a disproportionate fraction of new HIV infections in Africa and are a priority population for HIV prevention, including implementation of preexposure prophylaxis (PrEP). The overarching goal of this project was to demonstrate the feasibility of integrating PrEP delivery within routine family planning (FP) clinics to serve as a platform to efficiently reach at-risk adolescent girls and young women (AGYW) for PrEP in HIV high-burden settings. Methods and findings The PrEP Implementation in Young Women and Adolescents (PrIYA) program is a real-world implementation program to demonstrate integration of PrEP delivery for at-risk AGYW in FP clinics in Kisumu, Kenya. Between November 2017 and June 2018, women aged 15 to 45 from the general population seeking FP services at 8 public health clinics were universally screened for HIV behavioral risk factors and offered PrEP following national PrEP guidelines. We evaluated PrEP uptake and continuation, and robust Poisson regression methods were used to identify correlates of uptake and early continuation of PrEP, with age included as a one-knot linear spline. Overall, 1,271 HIV-uninfected women accessing routine FP clinics were screened for PrEP; the median age was 25 years (interquartile range [IQR]: 22-29), 627 (49%) were Conclusions In this real-world PrEP implementation program in Kenya, integration of universal screening and counseling for PrEP in FP clinics was feasible, making this platform a potential 'one-stop' location for FP and PrEP. There was a high drop-off in PrEP continuation, but a subset of women continued PrEP use at least through 1 month, possibly indicating further reflection or decision-making on PrEP use. Greater efforts to support PrEP normalization and persistence for African women are needed to help women navigate their decisions about HIV prevention preferences as their reproductive goals and HIV vulnerability evolve., Author(s): Kenneth K.

: Introduction: Partner notification services (PNS) increase the HIV status knowledge and linkage to care and treatment. However, it is unclear if PNS can facilitate linkage of HIV‐negative partners to prevention services such as pre‐exposure prophylaxis (PrEP). Using qualitative methods, we explored provider perspective regarding the interaction of PrEP availability, PNS and antiretroviral treatment (ART) outcomes within a project integrating PrEP services into HIV care clinics in eight counties in western and central Kenya. Methods: From May 2017 to August 2018, data on integrated PrEP service delivery including its interaction with PNS were collected through 71 key informant in‐depth interviews with healthcare providers and 24 standardized technical assistance reports summarizing implementation at the participating clinics. Thus, the perspective was from that of providers; analyses focused on emergent themes relating PNS to PrEP and ART services. Results: Providers found that PrEP integration provided an additional concrete prevention option for HIV‐negative partners and created a motivation to offer PNS to persons living with HIV. PrEP availability also seemed to operate as an incentive for those living with HIV to participate in PNS, which in turn enhanced identification of potential PrEP clients and created an environment for discussing HIV transmission risk. Providers commented that initiating HIV‐negative partners on PrEP enhanced mutual monitoring of health outcomes, including improved adherence to ART by partners living with HIV. Clinics noted prioritizing people living with HIV with detectable viral loads for PNS in order to identify HIV‐negative partners who would benefit most from PrEP. Providers felt motivated by the apparent synergistic interaction of PNS, PrEP and ART. Conclusions: Providers felt that the integration of PrEP into HIV care clinics stimulated the provision of PNS, and PNS was used to improve the identification of potential PrEP clients. The integrated combination of PNS, PrEP and ART is synergistic and should be promoted in HIV clinics., Introduction Antiretroviral treatment (ART) to reduce the infectiousness of persons living with HIV and pre‐exposure prophylaxis (PrEP) for persons at‐risk of HIV to prevent HIV acquisition are extraordinarily effective strategies [...]

Background As pre-exposure prophylaxis (PrEP) becomes more widely used in heterosexual populations, an important consideration is its safety in infants who are breastfed by women taking PrEP. We investigated whether tenofovir and emtricitabine are excreted into breast milk and then absorbed by the breastfeeding infant in clinically significant concentrations when used as PrEP by lactating women. Methods and Findings We conducted a prospective short-term, open-label study of daily oral emtricitabine-tenofovir disoproxil fumarate PrEP among 50 HIV-uninfected breastfeeding African mother-infant pairs between 1-24 wk postpartum (ClinicalTrials.gov Identifier: NCT02776748). The primary goal was to quantify the steady-state concentrations of tenofovir and emtricitabine in infant plasma ingested via breastfeeding. PrEP was administered to women through daily directly observed therapy (DOT) for ten consecutive days and then discontinued thereafter. Non-fasting peak and trough samples of maternal plasma and breast milk were obtained at drug concentration steady states on days 7 and 10, and a single infant plasma sample was obtained on day 7. Peak blood and breast milk samples were obtained 1-2 h after the maternal DOT PrEP dose, while maternal trough samples were obtained at the end of the PrEP dosing interval (i.e., 23 to 24 h) after maternal DOT PrEP dose. Tenofovir and emtricitabine concentrations were quantified using liquid chromatography-tandem mass spectrometry (LC-MS/MS) assays. Of the 50 mother-infant pairs enrolled, 48% were [less than or equal to]12 wk and 52% were 13-24 wk postpartum, and median maternal age was 25 y (interquartile range [IQR] 22-28). During study follow-up, the median (IQR) daily reported frequency of infant breastfeeding was 15 times (12 to 18) overall, 16 (14 to 19) for the [less than or equal to]12 weeks, and 14 (12 to 17) for the 13-24 wk infant age groups. Overall, median (IQR) time-averaged peak concentrations in breast milk were 3.2 ng/mL (2.3 to 4.7) for tenofovir and 212.5 ng/mL (140.0 to 405.0) for emtricitabine. Similarly, median (IQR) time-averaged trough concentrations in breast milk were 3.3 ng/mL (2.3 to 4.4) for tenofovir and 183.0 ng/mL (113.0 to 250.0) for emtricitabine, reflecting trough-to-peak breast milk concentration ratios of 1.0 for tenofovir and 0.8 for emtricitabine, respectively. In infant plasma, tenofovir was unquantifiable in 46/49 samples (94%), but emtricitabine was detectable in 47/49 (96%) (median [IQR] concentration: 13.2 ng/mL [9.3 to 16.7]). The estimated equivalent doses an infant would ingest daily from breastfeeding were 0.47 [mu]g/kg (IQR 0.35 to 0.71) for tenofovir and 31.9 [mu]g/kg (IQR 21.0 to 60.8) for emtricitabine, translating into a The key study limitation was that only a single infant sample was collected to minimize venipunctures for the children. However, maternal daily DOT and specimen collection at drug concentration steady state provided an adequate approach to address the key research question. Importantly, there was minimal variation in breast milk concentrations of tenofovir and emtricitabine (respective median trough-to-peak concentration ratio ~1), demonstrating that infants were exposed to consistent drug dosing via breast milk. Conclusion In this short-term study of daily directly observed oral PrEP in HIV-uninfected breastfeeding women, the estimated infant doses from breast milk and resultant infant plasma concentrations for tenofovir and emtricitabine were 12,500 and >200-fold lower than the respective proposed infant therapeutic doses, and tenofovir was not detected in 94% of infant plasma samples. These data suggest that PrEP can be safely used during breastfeeding with minimal infant drug exposure. Trial Registration ClinicalTrials.gov, Identifier: NCT02776748, Author(s): Kenneth K.

Background: In 2017, the Kenyan Ministry of Health integrated provision of pre-exposure prophylaxis (PrEP) into public HIV-1 care clinics as a key component of the national HIV-1 prevention strategy. Estimates of the cost of PrEP provision are needed to inform the affordability and cost-effectiveness of PrEP in Kenya.Methods: We conducted activity-based micro-costing from the payer perspective to estimate both the financial and economic costs of all resources and activities required to provide PrEP in Kenya's public sector. We estimated total and unit costs in 2019 United States dollars from a combination of project expense reports, Ministry of Health training reports, clinic staff interviews, time-and-motion observations, and routinely collected data from PrEP recipient files from 25 high-volume HIV-1 care clinics.Results: In the first year of programmatic PrEP delivery in 25 HIV-1 care clinics, 2,567 persons initiated PrEP and accrued 8,847 total months of PrEP coverage, accounting for 2 % of total outpatient clinic visits. The total financial cost to the Ministry of Health was $91,175, translating to an average of $10.31 per person per month. The majority (69 %) of financial costs were attributable to PrEP medication, followed by administrative supplies (17 %) and training (9 %). Economic costs were higher ($188,584 total; $21.32 per person per month) due to the inclusion of the opportunity cost of staff time re-allocated to provide PrEP and a proportional fraction of facility overhead. The vast majority (88 %) of the annual $80,811 economic cost of personnel time was incurred during activities to recruit new clients (e.g., discussion of PrEP within HIV-1 testing and counselling services), while the remaining 12 % was for activities related to both initiation and maintenance of PrEP provision (e.g., client consultations, technical advising, support groups).Conclusions: Integration of PrEP provision into existing public health HIV-1 care service delivery platforms resulted in minimal additional staff burden and low incremental costs. Efforts to improve the efficiency of PrEP provision should focus on reductions in the cost of PrEP medication and extra-clinic demand creation and community sensitization to reduce personnel time dedicated to recruitment-related activities.Trial Registration: ClinicalTrials.gov registration NCT03052010 .

Communication around condom use in the context of PrEP services presents a potential conundrum for patients and providers. Within the Partners Scale-Up Project, which supports integration of PrEP delivery in HIV care clinics, we interviewed 41 providers and 61 PrEP users and identified themes relating to condom messaging and use. Most providers counselled PrEP initiators to always use both PrEP and condoms, except when trying to conceive. However, others reported contexts and rationales for not emphasizing condom use. Providers reported that PrEP users were sometimes confused, even frustrated, with their insistence on using condoms in addition to PrEP. PrEP users generally regarded PrEP as a more feasible and desirable HIV prevention method than condoms, enabling increased sexual pleasure and conception, and reducing the conflict and stigma associated with condom use. Innovative approaches to condom counselling in PrEP programs are needed. [ABSTRACT FROM AUTHOR]

Background: Wide-scale implementation of oral tenofovir-based pre-exposure prophylaxis (PrEP) for HIV prevention is now policy in many settings. However, the optimal frequency for monitoring kidney function remains uncertain. We investigated the impact of 6-monthly compared to 3-monthly creatinine clearance (CrCl) monitoring on the identification of moderate kidney dysfunction, defined as CrCl <60 mL/min. Methods: Data were from two prospective daily oral PrEP studies in Kenya and Uganda: the Partners PrEP Study, a randomized safety and efficacy trial of PrEP that conducted 3-monthly CrCl monitoring (n=4404) and the Partners Demonstration Project (n=954), an open-label delivery study of PrEP that used 6-monthly monitoring. CrCl =60 mL/min was required for enrollment in both studies. Abnormal results were followed with confirmatory testing within approximately 1 week. Follow-up was for up to 24 months. Results: Of 5358 participants included in the analysis, 87% were <45 years, a third were female, and 21% had a baseline CrCl between 60-90 mL/min. Confirmed CrCl <60 mL/min events were rare, occurring in 52 individuals (<1%) in 24-months. The 12-month cumulative proportion of persons with CrCl <60 mL/min was 0.2% with 3-monthly screening and 0.5% with 6-monthly screening. Older age (>45 years), lower weight (<55 kg), elevated blood pressure (>140 mm/Hg), and baseline CrCl between 60-90 mL/min were independently associated with CrCl decline <60 mL/min during follow up. Conclusions: In these two PrEP studies, with a generally young participants, the occurrence and pattern of clinically relevant decline in CrCl were not qualitatively different based on 3- or 6-monthly CrCl monitoring schedule. These data suggest that for most persons receiving PrEP for up to 24 months, less frequent CrCl monitoring would be safe and reduce required expenditures for.

Background Pre-exposure prophylaxis (PrEP) with emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) reduces the risk of HIV seroconversion but may promote bone mineral density (BMD) decline. The mechanisms of BMD decline with FTC/TDF remain unclear, and studies in HIV-positive individuals have been confounded by the effects of HIV and concomitant antiretroviral medications. We evaluated the impact of FTC/TDF on biomarkers of bone remodeling and bone mineral metabolism in HIV-negative men and women enrolled in the Partners PrEP Study. Methods In a random sample of HIV-negative participants randomized to FTC/TDF PrEP (n = 50) or placebo (n = 50), serum parathyroid hormone (PTH), bone biomarkers (C-telopeptide, procollagen 1 intact N-terminal propeptide, and sclerostin), and plasma fibroblast growth factor 23 were measured at baseline and month 24, and the percentage change was compared between groups. In a complementary analysis, we compared the change in biomarkers between participants with and without a 25% decline in glomerular filtration rate (GFR) on FTC/TDF. Results Baseline characteristics were similar between the groups (median age, 38 years; 40% women). Vitamin D insufficiency was common, but baseline GFR and PTH were in the normal range. We observed a significantly greater percent increase in serum C-telopeptide in participants randomized to FTC/TDF vs placebo (P =.03), suggesting an increase in bone remodeling. We observed no differences in the other biomarkers, or in a separate analysis comparing participants with and without a decline in GFR. Conclusions Increased bone remodeling may mediate the BMD decline observed with tenofovir-containing PrEP and antiretroviral therapy, independent of a TDF-mediated decrease in kidney function.

Introduction: Women engaging in sex work (WESW) have 21 times the risk of HIV acquisition compared with the general population. However, accessing HIV pre-exposure prophylaxis (PrEP) remains challenging, and PrEP initiation and persistence are low due to stigma and related psychosocial factors. The WiSSPr (Women in Sex work, Stigma and PrEP) study aims to (1) estimate the effect of multiple stigmas on PrEP initiation and persistence and (2) qualitatively explore the enablers and barriers to PrEP use for WESW in Lusaka, Zambia., Methods and Analysis: WiSSPr is a prospective observational cohort study grounded in community-based participatory research principles with a community advisory board (CAB) of key population (KP) civil society organi sations (KP-CSOs) and the Ministry of Health (MoH). We will administer a one-time psychosocial survey vetted by the CAB and follow 300 WESW in the electronic medical record for three months to measure PrEP initiation (#/% ever taking PrEP) and persistence (immediate discontinuation and a medication possession ratio). We will conduct in-depth interviews with a purposive sample of 18 women, including 12 WESW and 6 peer navigators who support routine HIV screening and PrEP delivery, in two community hubs serving KPs since October 2021. We seek to value KP communities as equal contributors to the knowledge production process by actively engaging KP-CSOs throughout the research process. Expected outcomes include quantitative measures of PrEP initiation and persistence among WESW, and qualitative insights into the enablers and barriers to PrEP use informed by participants' lived experiences., Ethics and Dissemination: WiSSPr was approved by the Institutional Review Boards of the University of Zambia (#3650-2023) and University of North Carolina (#22-3147).

Background: People living with HIV require reliable access to and adequate supply of antiretroviral therapy (ART) for viral suppression. The Deliver Health Study, a randomized trial conducted during the COVID-19 pandemic, found that home-delivered ART significantly increased viral suppression compared with clinic-based care. The effect of changing COVID-19 alert levels on self-reported ART use has not been quantified., Setting: KwaZulu-Natal, South Africa., Methods: Adults living with HIV were followed in the Deliver Health Study during October 2019-December 2020. We used difference-in-differences (DiD) to estimate the effect of changing COVID-19 alert levels during 3 distinct periods on self-reported missed ART doses (missed 0 vs. ≥1 doses in past week) for participants receiving home-delivered vs. clinic-based refills. We additionally estimated the effect of changing COVID-19 alert levels on late clinic ART refill visits (late vs. on-time). We used relative risk regression for both binary outcomes., Results: Of 155 participants, 46% were women and the median age was 36 years. The mean number of missed weekly doses was 0.11, 0, and 0.12 in the home-delivery group and 0.09, 0.08, and 0.18 in the clinic group during periods 1, 2, and 3, respectively. There were no differences in relative risk of self-reported daily ART use between refill groups when comparing across periods [DiDperiod 2 vs. 1 = 1.05; 95% confidence interval: 0.97, 1.13 and DiDperiod 3 vs. 2 = 0.99; 95% confidence interval (CI): 0.91, 1.08]. In the clinic group, the risk of late refill visits was significantly higher during COVID-19 restrictions (vs. before alert level 5 implementation) and even after the COVID-19 alert level was downgraded to level 1 (RRperiod 2 vs. 1 = 1.83, 95% CI: 1.34, 2.51 and RRperiod 3 vs. 2 = 1.71; 95% CI: 1.43, 2.04)., Conclusion: The COVID-19 pandemic did not differentially impact self-reported ART adherence by the method of ART refills, but the risk of late clinic refill visits was significantly higher during COVID-19 restrictions and sustained after restrictions were loosened., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Partners of persons living with HIV (PLHIV) are at a high risk of HIV acquisition, particularly if PLHIV are newly diagnosed or not virally suppressed. A focused partner HIV testing strategy could stimulate efficient identification of persons for pre-exposure prophylaxis (PrEP) or antiretroviral therapy (ART) programs., Methods: We sequentially implemented 2 partner testing strategies at 2 Kenyan HIV clinics: (1) an invitation for clinic-based testing and (2) HIV self-testing (HIVST) kits distribution to index PLHIV. For each testing strategy, we enrolled approximately 150 consecutive index PLHIV with partners of unknown HIV status, not on ART, <6 months on ART, or who had detectable viral load. We compared partner engagement, testing uptake, and linkage for ART or PrEP between the 2 testing strategies., Results: Of 313 index PLHIV enrolled (160 in invitation, 153 in HIVST), the median age was 32 years (interquartile range 26-40) and 76% were women. Overall, 73% of participants (229) discussed HIV testing with their partners: 76% (121) in the invitation strategy vs 71% (108) in the HIVST strategy [adjusted odds ratio (adjOR): 0.54, 95% confidence interval (CI): 0.31 to 0.97]. Overall, 52% (79) partners in the HIVST strategy tested vs 38% (60) in the invitation strategy (adjOR: 1.78, 95% CI: 1.13 to 2.78). Among partners engaged, 73% in the HIVST strategy vs 50% in the invitation tested (adjOR: 2.68, 95% CI: 1.46 to 4.96); 25% (35/139) tested positive for HIV. Eighty-nine percentage (31/35) who tested positive initiated treatment, but only 21% (20/93) who tested negative initiated PrEP., Conclusions: HIVST kit distribution to PLHIV with partners of unknown HIV status effectively increased partner testing. Only one-fifth of partners who tested negative initiated PrEP-thus innovations to link to prevention services are urgently needed., Competing Interests: J.M.B. is an employee of Gilead Sciences.
