Safety and adherence of bictegravir/emtricitabine/tenofovir alafenamide for HIV post-exposure prophylaxis among adults in Guiyang China: a prospective cohort study. BMC Infect Dis 2024; 24:565. [PMID: 38844855 PMCID: PMC11157740 DOI: 10.1186/s12879-024-09407-9] [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: 11/23/2023] [Accepted: 05/15/2024] [Indexed: 06/09/2024] Open
Abstract
BACKGROUND The effectiveness of post-exposure prophylaxis (PEP) depends on participants adherence, making it crucial to assess and compare regimen options to enhance human immunodeficiency virus (HIV) prophylaxis strategies. However, no prospective study in China has shown that the completion rate and adherence of single-tablet regimens in HIV PEP are higher than those of multi-tablet preparations. Therefore, this study aimed to assess the completion rate and adherence of two HIV PEP regimens. METHODS In this single-center, prospective, open-label cohort study, we included 179 participants from May 2022 to March 2023 and analyzed the differences in the 28-day medication completion rate, adherence, safety, tolerance, and effectiveness of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) and tenofovir disoproxil fumarate, emtricitabine, and dolutegravir (TDF/FTC + DTG). RESULTS The PEP completion rate and adherence were higher in the BIC/FTC/TAF group than in the TDF/FTC + DTG group (completion rate: 97.8% vs. 82.6%, P = 0.009; adherence: 99.6 ± 2.82% vs. 90.2 ± 25.29%, P = 0.003). The incidence of adverse reactions in the BIC/FTC/TAF and TDF/FTC + DTG groups was 15.2% and 10.3% (P = 0.33), respectively. In the TDF/FTC + DTG group, one participant stopped PEP owing to adverse reactions (1.1%). No other participants stopped PEP due to adverse events. CONCLUSIONS BIC/FTC/TAF and TDF/FTC + DTG have good safety and tolerance as PEP regimens. BIC/FTC/TAF has a higher completion rate and increased adherence, thus, is recommended as a PEP regimen. These findings emphasize the importance of regimen choice in optimizing PEP outcomes. TRIAL REGISTRATION The study was registered in the Chinese Clinical Trial Registry (registration number: ChiCTR2200059994(2022-05-14), https://www.chictr.org.cn/bin/project/edit?pid=167391 ).

Abstract
Post-exposure prophylaxis (PEP) to prevent HIV acquisition has been recommended for over three decades, but remains underutilised. Over the past decade, clinical trials have established the safety and tolerability of newer PEP regimens, particularly those containing integrase strand transfer inhibitors (INSTIs) combined with a tenofovir and lamivudine or emtricitabine backbone. Several of these regimens were better tolerated than historical controls. Studies in macaques found that shorter courses of PEP with INSTIs were effective, particularly if dosing occurred close to the time of retroviral exposure. Despite the increase in well tolerated options, PEP seems to be underused globally and links to other prevention services are suboptimal. Interventions to increase provider and community awareness of PEP are needed.

[PMID: 38050483 PMCID: PMC10693755 DOI: 10.2147/hiv.s385877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Accepted: 10/27/2023] [Indexed: 12/06/2023] Open
Abstract
Bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) is a single-tablet antiretroviral therapy regimen. B/F/TAF has become a popular treatment choice because of its small tablet size, high barrier to resistance, favorable tolerability, and limited drug-drug interaction profile. Continued research on B/F/TAF has revealed additional potential for this regimen. This review presents recent literature supporting the use of B/F/TAF as an option for consolidating therapy and maintaining virologic suppression in individuals despite M184V/I mutations. Additionally, children are a unique patient population with limited antiviral options. Standard dose B/F/TAF has demonstrated similar drug exposure in children and adolescents as adults, and low-dose B/F/TAF is approved for children living with HIV greater than two years of age and weighing at least 14 kg. Data supporting this recommendation is described in this review. Finally, despite a lack of prospective data, B/F/TAF may have a role in the future of pre- and post-exposure prophylaxis. This review discusses these discoveries and the continued exploration of the hidden potential of B/F/TAF.

Abstract
Background New regimens may provide better tolerability, convenience, and safety for nonoccupational human immunodeficiency virus (HIV) postexposure prophylaxis (PEP). For this reason, we evaluated the single-tablet regimen of doravirine/lamivudine/tenofovir disoproxil fumarate (DOR/3TC/TDF) for 28 days. Methods This was a prospective, open-label, single-arm trial including individuals with potential HIV-1 exposure within 72 hours. The primary endpoint was noncompletion of PEP at day 28. Secondary endpoints were adverse effects, adherence, and rate of seroconversion. We performed follow-up at day 7, week 4, and week 12. Results Between September 2019 and March 2022, the study enrolled 399 individuals. Median age was 30 (interquartile range [IQR], 27-36) years, and 91% (n = 364) were male. The mode of exposure was sex between men in 84% (n = 331) of cases; risk assessment for HIV-1 transmission was considered as "high" in 97% (n = 385) of the participants. Median time from exposure to consultation was 24 (IQR, 13-40) hours. Noncompletion of PEP was 29% (n = 114) (95% confidence interval [CI], 24%-33%) and 20% (n = 72) (95% CI, 16%-25%) per modified intention-to-treat. Main reasons for noncompletion were loss to follow-up (n = 104 [91%]) and intolerance (n = 8 [7%]). Older age was associated with a lower risk of premature discontinuation (OR, 0.94; P < .001). One hundred twenty-three (31%) participants reported adverse events, mostly mild and self-limited (82%); discontinuation occurred in 8 cases (2%). Adherence to PEP in the assessed users was 96%. There were no HIV seroconversions. Conclusions DOR/3TC/TDF is a well-tolerated option for nonoccupational PEP. Clinical Trials Registration. NCT04233372.

The Use of HIV Pre- and Postexposure Prophylaxis Among a Web-Based Sample of HIV-Negative and Unknown Status Cisgender and Transgender Sexual Minority Men: Cross-sectional Study. JMIR Public Health Surveill 2022; 8:e31237. [PMID: 36306518 PMCID: PMC9804091 DOI: 10.2196/31237] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 12/08/2021] [Accepted: 10/28/2022] [Indexed: 11/07/2022] Open
Abstract
BACKGROUND HIV disproportionately affects sexual minority men (SMM) in the United States. OBJECTIVE We sought to determine past HIV postexposure prophylaxis (PEP) use and current and prior pre-exposure prophylaxis (PrEP) use among a web-based sample of cisgender and transgender men who have sex with men. METHODS In 2019, HIV-negative and unknown status SMM (n=63,015) were recruited via geosocial networking apps, social media, and other web-based venues to participate in a brief eligibility screening survey. Individuals were asked about past PEP use and current and prior PrEP use. We examined associations of demographics, socioeconomic indicators, and recent club drug use with PEP and PrEP use, as well as the association between past PEP use and current and prior PrEP use using generalized linear models and multinomial logistic regression. Statistical significance was considered at P<.001, given the large sample size; 99.9% CIs are reported. RESULTS Prior PEP use was reported by 11.28% (7108/63,015) of the participants, with current or prior PrEP use reported by 21.95% (13,832/63,015) and 8.12% (5118/63,015), respectively. Nearly half (3268/7108, 46%) of the past PEP users were current PrEP users, and another 39.9% (2836/7108) of the participants who reported past PEP use also reported prior PrEP use. In multivariable analysis, past PEP use was associated with current (relative risk ratio [RRR] 23.53, 99.9% CI 14.03-39.46) and prior PrEP use (RRR 52.14, 99.9% CI 29.39-92.50). Compared with White men, Black men had higher prevalence of past PEP use and current PrEP use, Latino men had higher prevalence of PEP use but no significant difference in PrEP use, and those identifying as another race or ethnicity reported higher prevalence of past PEP use and lower current PrEP use. Past PEP use and current PrEP use were highest in the Northeast, with participants in the Midwest and South reporting significantly lower PEP and PrEP use. A significant interaction of Black race by past PEP use with current PrEP use was found (RRR 0.57, 99.9% CI 0.37-0.87), indicating that Black men who previously used PEP were less likely to report current PrEP use. Participants who reported recent club drug use were significantly more likely to report past PEP use and current or prior PrEP use than those without recent club drug use. CONCLUSIONS PrEP use continues to be the predominant HIV prevention strategy for SMM compared with PEP use. Higher rates of past PEP use and current PrEP use among Black SMM are noteworthy, given the disproportionate burden of HIV. Nonetheless, understanding why Black men who previously used PEP are less likely to report current PrEP use is an important avenue for future research.

Abstract
BACKGROUND Single-tablet regimen (STR) provides a convenient once-daily regimen for the prevention of human immunodeficiency virus (HIV) infection. Here, we investigated the safety and tolerability of coformulated bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) as a three-drug, STR for post-exposure prophylaxis (PEP) in Chinese individuals. METHODS This was a prospective, open-label, single-arm trial conducted in a sexually transmitted diseases and acquired immunodeficiency syndrome clinic of a tertiary hospital in Beijing, China. Adults requiring PEP were prescribed BIC/FTC/TAF one pill once a day for 28 days. Clinical and laboratory data were collected and analyzed at baseline, weeks 2, 4, 8, 12, and 24. RESULTS Of 112 participants enrolled in the study, 109 (97.3%) were male and the mean age was 30 ± 8 years. PEP completion was 96.4% (95% confidence interval: 91.1-99.0%). Two participants stopped PEP after 2 days because the source partner was identified as HIV uninfected. One participant was excluded due to hepatitis B virus infection according to the exclusion criteria. One discontinued due to the participant's decision. No participant acquired HIV through week 24. Adherence was 98.9% (standard deviation [SD]: 3.3%) by self-reporting and 98.5% (SD: 3.5%) by pill count. Only five participants experienced mild clinical adverse events attributed to the study drug (including headache, diarrhea, and nausea) and four participants had elevated serum creatinine (grade 1). CONCLUSIONS A once daily, STR of BIC/FTC/TAF used as PEP was safe and well-tolerated with a high rate of completion and adherence in Chinese. BIC/FTC/TAF may be a good option for PEP.

Abstract
BACKGROUND Antiretroviral post-exposure prophylaxis (PEP) is recommended to prevent HIV infection after a high-risk exposure, but current regimens have presented challenges in tolerability, regimen completion, and potential drug-drug interactions. Because coformulated bictegravir, emtricitabine, and tenofovir alafenamide [BIC/FTC/tenofovir alafenamide (TAF)] is effective for HIV treatment, it was evaluated for use for PEP. SETTING Boston community health center. METHODS Individuals accessing PEP were enrolled in an open-label study of coformulated BIC/FTC/TAF, taken as one pill daily for 28 days. Pearson's χ2 and Fisher's exact tests were used to assess whether BIC/FTC/TAF differed with respect to side effects and regimen completion rates compared with historical PEP regimens. RESULTS Between August, 2018 and March, 2020, 52 individuals enrolled in the study. Most identified as cisgender gay (67.3%) or bisexual (11.5%) men, but 7.7% identified as cisgender heterosexual men and 3.8% cisgender heterosexual women. The most common regimen side effects were nausea or vomiting (15.4%), fatigue (9.6%), and diarrhea/loose stools (7.7%), which were less common than historical controls using other PEP regimens, including those containing other integrase strand transfer inhibitors. Only 1 participant discontinued the regimen because of fatigue, and all other side effects were self-limited. Almost all participants (90.4%) completed the indicated regimen, which was a higher completion rate compared with earlier PEP regimens, and none became HIV-positive. CONCLUSIONS BIC/FTC/TAF coformulated as a single daily pill was found to be safe, well-tolerated, and highly acceptable when used for PEP, and compared more favorably than historical PEP regimens used at an urban health center.

Abstract
We present the updated British Association for Sexual Health and HIV (BASHH) guidelines for post-exposure prophylaxis (PEP) to HIV following sexual exposures, occupational exposures and other nonoccupational exposures in the community. This serves as an update to the 2015 BASHH guideline on PEP following sexual exposures and the 2008 Expert Advisory Group on AIDS guidelines on HIV PEP. We aim to provide evidence-based guidance on best clinical practice in the provision, monitoring and support of PEP for the prevention of HIV acquisition following sexual, occupational and other nonoccupational exposures in the community. The guideline covers when to prescribe PEP, what antiretroviral agents to use and how to manage PEP. This includes (i) evidence of PEP efficacy; (ii) evidence relating to individual-level efficacy of antiretroviral therapy to prevent the sexual transmission of HIV; (iii) data on the detectable (transmissible) prevalence of HIV in specific populations; (iv) risk of HIV transmission following different types of sexual and occupational exposure; (v) baseline risk assessment; (vi) drug regimens and dosing schedules; (vii) monitoring PEP; (viii) baseline and follow-up blood-borne virus testing; (ix) the role of PEP within broader HIV prevention strategies, for example, HIV pre-exposure prophylaxis (PrEP). The guideline also covers special scenarios such as PEP in pregnancy, breastfeeding and chronic hepatitis B virus infection, and when PEP should be considered in people using HIV PrEP. The guidelines are aimed at clinical professionals directly involved in PEP provision and other stakeholders in the field. A proforma to assist PEP consultations is included. A public consultation process was undertaken prior to finalizing the recommendations.

COVID-19-Related Disruptions to HIV Testing and Prevention Among Young Sexual Minority Men 17-24 Years Old: A Qualitative Study Using Synchronous Online Focus Groups, April-September 2020. ARCHIVES OF SEXUAL BEHAVIOR 2022; 51:303-314. [PMID: 34773214 PMCID: PMC8589091 DOI: 10.1007/s10508-021-02166-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/19/2021] [Revised: 09/23/2021] [Accepted: 09/24/2021] [Indexed: 05/20/2023]
Abstract
Prior research has highlighted the impact of the COVID-19 pandemic on HIV prevention services within the U.S., but few studies have explored this impact through an exploratory, qualitative lens. In this study, we sought to highlight the voices of young sexual minority men (YSMM) 17-24 years old and explored the perceived impact of the pandemic on HIV prevention among a diverse, nationwide sample of YSMM who participated in synchronous online focus group discussions between April and September 2020. Forty-one YSMM described the negative effects of the COVID-19 pandemic on HIV testing and prevention services, including limited and disrupted access to HIV testing, HIV pre-exposure prophylaxis (PrEP), and HIV post-exposure prophylaxis. COVID-19-related challenges were compounded by ongoing, pre-COVID-19 barriers experienced by YSMM in the U.S. For instance, many YSMM relocated back home with family, causing men to avoid HIV prevention services for fear of outing themselves to relatives. YSMM also worried about placing their family at increased risk of COVID-19 by attending clinical appointments. YSMM who did seek HIV prevention services, including access to PrEP, experienced significant barriers, including limited appointment availability and services not tailored to YSMM. Further efforts are needed to support YSMM re-engaging in HIV prevention during and after the COVID-19 era.

Tolerability and Adherence of Antiretroviral Regimens Containing Long-Acting Fusion Inhibitor Albuvirtide for HIV Post-Exposure Prophylaxis: A Cohort Study in China. Infect Dis Ther 2021; 10:2611-2623. [PMID: 34586592 PMCID: PMC8572943 DOI: 10.1007/s40121-021-00540-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Accepted: 09/17/2021] [Indexed: 01/13/2023] Open
Abstract
INTRODUCTION There have been no prospective clinical studies investigating adherence and tolerability of HIV post-exposure prophylaxis (PEP) in China. Tolerability, adherence, and transmitted drug resistance are concerns, especially when single-tablet regimen (STR) usage is low. The present study aimed to explore the safety, tolerability, and adherence of regimens containing albuvirtide (ABT) compared with recommended non-STR antiretrovirals for HIV PEP. METHODS This was a prospective, open-label, multicenter cohort study. The subjects were stratified into 3 groups based on their preference: ABT + Dolutegravir (DTG) (Group 1), ABT + Tenofovir disoproxil fumarate (TDF) + Lamivudine (3TC) (Group 2), and DTG + TDF + 3TC (Group 3). All enrolled subjects received PEP within 72 h after exposure and continued for 28 days, and were followed-up for 12 weeks. RESULTS A total of 330 participants were enrolled in the three groups. Most participants were male (87.2%). Sexual contact was the most frequent mode of exposure (91.9%). The average time from exposure to treatment was 26.8 ± 19.5 h. There were no statistically significant differences between the three study groups with respect to completion of oral medication at 28 days. The 28-day completion rate was shown to be significantly higher with ABT versus oral (88.9% vs. 64.0%; p < 0.0001), and adherence with ABT was 94.4% compared to 75.7% with oral PEP (p < 0.0001). Subjects in ABT-containing Group 1 exhibited higher adherence than those in Group 3 (87.3% vs. 72.9%; p < 0.05). None of the participants reported serious adverse drug reactions which led to withdrawal from the study. All the drug regimens were found to be safe and well tolerated. No HIV incident case was observed during the study period. CONCLUSIONS ABT-containing regimens (ABT + DTG or ABT + TDF + 3TC) offer a good option for HIV PEP due to higher completion rates and adherence than the DTG + TDF + 3TC regimen. The overall safety was comparable and acceptable among the three groups. REGISTRATION The study was registered in Chinese Clinical Trial Registry with registration number (ChiCTR1900022881, http://www.chictr.org.cn/showprojen.aspx?proj=37395 ).

Abstract
Non-occupational post-exposure prophylaxis (nPEP) has been clinically recommended since 2005. HIV providers and non-HIV providers (n = 480) practicing within above-average HIV prevalence ZIP codes of the 10 U.S. cities with greatest overall HIV prevalence participated in a cross-sectional survey between July 2014 and May 2015. Providers were asked about their awareness of post-exposure prophylaxis (PEP) and nPEP prescribing experience for patients with potential sexual exposures to HIV, which we coded into a PEP prescribing cascade with three categories: (1) PEP unaware, (2) PEP aware, no nPEP prescribing experience, and (3) nPEP prescribing experience. Overall, 12.5% were unaware of PEP, 43.5% were aware but hadn't prescribed nPEP, and 44.0% had prescribed nPEP for potential sexual exposures to HIV. Fewer providers practicing in the U.S. South had ever prescribed nPEP compared to providers in other regions (χ2= 39.91, p < 0.001). HIV providers, compared to non-HIV providers, were more likely to be classified in the nPEP prescription group compared to the PEP aware without nPEP prescription group (RRR = 2.96, p < 0.001). PrEP prescribers, compared to those PrEP unaware, were more likely to be classified in the nPEP prescription group compared to PEP aware without nPEP prescription group (RRR = 12.49, p < 0.001).

Abstract
BACKGROUND Postexposure prophylaxis (PEP) is a recommended public health intervention after a sexual assault to prevent HIV infection. METHODS We conducted a retrospective case-control study on how use of a single-tablet regimen (STR) of elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (Stribild) affected adherence to PEP and attendance of a follow-up visit to the STI clinic compared with those who received a multitablet regimen (MTR). Data from sexual assault victims consulting for PEP were prospectively recorded between January 2011 and December 2017. Data were systematically collected on patient demographics, time of medical contact, source risk factors, type of exposure, attendance to follow-up visit, reported completion of PEP and adherence based on pharmacy records. RESULTS A total of 422 patients received PEP following a sexual assault, of whom 52% had documented completion of a 28-day PEP regimen and 71% attended a follow-up clinic visit. Patients who received an elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (EVG/COBI/FTC/TDF)-based STR had a similar likelihood of attending their first follow-up visit (OR: 0.97; 95% CI: 0.64 to 1.48, p=0.90) but were more likely to complete the PEP regimen (OR: 1.70; 95% CI: 1.16 to 2.50, p=0.007). After adjusting for confounders, those who were prescribed an STR regimen were more likely to complete the PEP regimen (OR: 1.66, 95% CI: 1.09 to 2.53, p=0.019) than those who were prescribed an MTR such as stavudine/lamivudine/lopinavir/ritonavir or zidovudine/lamivudine/indinavir/ritonavir. CONCLUSIONS Sexual assault victims who were prescribed an STR based on EVG/COBI/FTC/TDF were more likely to complete PEP than those who were prescribed an MTR.

Abstract
Twenty-five years ago, the AIDS epidemic was wreaking havoc around the world. Although "HIV denialists" threatened to undermine research efforts to combat the epidemic, development of targeted antiviral therapy eventually provided effective treatment for the disease. Now the Lyme disease epidemic is wreaking havoc around the world, and "Lyme denialists" are undermining efforts to combat the epidemic. Drawing on our experience with the AIDS epidemic, there is a significant need to develop targeted therapy to control the Lyme disease epidemic.

Abstract
Over the past 30 years, significant advances have transformed the landscape of human immunodeficiency virus (HIV) care in the emergency department. Diagnosis and management of HIV has improved, resulting in a decline in the incidence of acquired immunodeficiency syndrome (AIDS)-defining infections. Advances in pharmacology have led to fewer serious medication toxicities and more tolerable regimens. Emergency providers have played an increasingly important role in HIV screening and diagnosis of acute infection. Provision of postexposure prophylaxis is expanding from a focus on occupational exposure to include all high-risk cases.

Abstract
Post-exposure prophylaxis (PEP) is a cost-effective, but underused HIV prevention strategy. PEP awareness, knowledge, access, and usage was assessed among young men of color who have sex with men (YMSMOC; n = 177), transgender women (TW; n = 182), and cisgender women of color (CWOC; n = 170) in New York City. 59% were aware of PEP: 80% among YMSMOC, 63% among TW and 34% among CWOC (p < 0.001). 13% had ever used PEP. PEP awareness was higher among YMSMOC with a recent HIV test and lower among those with ≥ 4 partners. PEP awareness was lower among TW who anticipated stigma and reported barriers to taking PEP, and higher among TW who exchanged sex for resources. Among CWOC, more barriers to taking PEP reduced the odds of PEP awareness. PEP education and outreach needs to be deliberate about population-specific campaigns, with a need to focus on reducing PEP stigma and other barriers which impede PEP access.
