Rates of Pre-exposure Prophylaxis Use and Discontinuation Among a Large U.S. National Sample of Sexual Minority Men and Adolescents.

Pre-exposure prophylaxis (PrEP) is highly effective in the prevention of HIV acquisition and was recently approved for those under 18 years of age. The primary goal of the present study was to understand the prevalence of and factors associated with PrEP use among a large sample of young and adult sexual minority men (Y/SMM). Participants came from a larger national sample of SMM. Data collected included demographics, substance use, PrEP use, and sexual risk. Participants were recruited via sexual networking/dating applications and resided in the U.S. including Puerto Rico, were at least 13 years old, self-reported being HIV-negative, and identified as male. The sample was divided into two groups: YSMM (13-24 years of age) and adult SMM (25 years of age and up). Multinomial logistic regressions examining associations with never, current, and former PrEP use were run with all variables of interest simultaneously entered into the models. Age was positively associated with both former and current PrEP use among YSMM. Additionally, YSMM who identified as gay (vs. bisexual), lived in the Northeast, Midwest, and West (vs. South), had their own health insurance (vs. those on their parent's), had recently been diagnosed with an STI, and had recently used a drug all had higher odds of being a current PrEP user compared to those that had never used PrEP. Among adult SMM, those who were older did not have higher odds of current PrEP use compared to those that had never used PrEP. Those who identified as queer (vs. gay), single, had their own or were on their partner's insurance (vs. parent's), recent condomless anal sex, recent STI diagnosis, recent drug use, and recent substance use all had higher odds of being a current PrEP user compared to those that had never used PrEP. Research is needed to address the disparities in PrEP uptake among YSMM. Interventions for PrEP access among those on their parents' insurance may also be necessary.

Human Immunodeficiency Virus/Sexually Transmitted Infection Counseling and Testing Services Received by Gay and Bisexual Men Using Preexposure Prophylaxis at Their Last PrEP Care Visit.

BACKGROUND: Preexposure prophylaxis (PrEP) reduces risk of human immunodeficiency virus infection for many gay and bisexual men (GBM); however, bacterial sexually transmitted infections associated with decreasing condom use among users is of concern. Center for Disease Control and Prevention's guidelines for PrEP use recommend bacterial sexually transmitted infection screening every 6 months. We sought to investigate comprehensive PrEP care, defined as: (1) discussion of sexual behavior, (2) blood sample, (3) urine sample, (4) rectal sample (rectal swab), and (5) throat sample (throat swab), provided at the user's last PrEP appointment. METHODS: The PrEP-using GBM in New York City (n = 104) were asked about their last PrEP care visit. We examined associations of demographics (age, race/ethnicity, and education), recent number of condomless anal sex events, time on PrEP, and health care provider type on receiving comprehensive care at last visit using fully adjusted binary logistic regression. RESULTS: At their last visit, nearly all men (94%) gave blood for testing, 88% provided a urine sample, and 77% discussed sexual behavior with their provider. However, only 51% reported having a rectal swab, and 48% an oral swab. Only 32% of men received comprehensive PrEP care at their last PrEP visit. Odds of receiving comprehensive care were significantly higher among younger men, men with a bachelor's degree or more education, and those who reported more condomless anal sex. CONCLUSIONS: Less than one third of GBM received comprehensive human immunodeficiency virus/sexually transmitted infection counseling and testing at their last visit. These findings indicate further efforts are needed to prepare health care providers for prescribing and managing patients on PrEP.

Will Gay and Bisexual Men Taking Oral Pre-exposure Prophylaxis (PrEP) Switch to Long-Acting Injectable PrEP Should It Become Available?

Oral pre-exposure prophylaxis (PrEP) is highly effective at reducing HIV transmission risk and is CDC recommended for many gay, bisexual, and other men who have sex with men (GBM). We sought to investigate awareness of and preference for using long-acting injectable PrEP (LAI-PrEP) among GBM currently taking oral PrEP (n = 104), and identify their concerns. About half of GBM had heard of LAI-PrEP, and 30.8% specifically preferred LAI-PrEP. GBM with more concerns about the level of protection and drug half-life of LAI-PrEP had lower odds of preferring LAI-PrEP. Given that daily pill adherence is a challenge for some on PrEP, it is important to investigate the degree to which those on PrEP might consider LAI-PrEP as an alternative.

Preferences for Sexual Health Smartphone App Features Among Gay and Bisexual Men.

Given the popularity of geosocial networking applications ("apps") among gay, bisexual, and other men who have sex with men (GBMSM), this study sought to examine GBMSM's willingness to use sexual health and behavior tracking features if integrated within apps they are already using to meet sexual partners. Most GBMSM (91%) recruited on a popular app reported interest in one or more sexual health app features, including features to find LGBT-friendly providers (83%), receive lab results (68%), schedule appointment reminders (67%), chat with a healthcare provider (59%), and receive medication reminder alerts (42%). Fewer GBMSM were interested in tracking and receiving feedback on their sexual behavior (35%) and substance use (24%). Our data suggest that integrating sexual health and behavior tracking features for GBMSM who use apps could be promising in engaging them in HIV prevention interventions. Further research is needed on GBMSM's perspectives about potential barriers in using such features.

Why I Quit Pre-Exposure Prophylaxis (PrEP)? A Mixed-Method Study Exploring Reasons for PrEP Discontinuation and Potential Re-initiation Among Gay and Bisexual Men.

Literature concerning pre-exposure prophylaxis (PrEP) among gay and bisexual identifying men (GBM) has explored facilitators and barriers to uptake and adherence. Far less reported are the reasons why GBM discontinue PrEP use. A national sample of 1071 GBM completed surveys about PrEP use and discontinuation. Participants who were still taking PrEP the 24-month follow up were compared to those that had stopped. Eighteen percent (n = 31) of GBM who reported ever using PrEP discontinued use. Younger (AOR = 0.96; 95% CI 0.92-1.00), and unemployed (AOR = 4.58; 95% CI 1.43-14.70) GBM were more likely to discontinue PrEP than their counterparts. Those that discontinued provided details on why via a free response question. The most common reasons for discontinuation were lower perceived HIV risk (50%) and cost/insurance (30%). Reasons for potential re-initiation included higher-risk sexual activities and changes to structural related barriers. More research is needed to inform interventions on how GBM can continue taking PrEP during changes to employment that effect insurance coverage and cost.

Sexually Explicit Media and Condomless Anal Sex Among Gay and Bisexual Men.

Gay and bisexual men (GBM) have reported viewing significantly more sexually explicit media (SEM) than heterosexual men. There is some evidence that SEM depicting bareback anal sex may be linked to engagement in condomless anal sex (CAS) and thus HIV/STI transmission among GBM. A nationwide sample of HIV-negative GBM in the U.S. completed an online survey that included measures on SEM consumption (both overall frequency and percentage viewed depicting bareback sex) and reported on CAS in the past 3 months. Data showed that there was no main effect for the frequency of SEM watched in association on either the number of CAS acts with casual partners or the probability of engaging in CAS during a casual sex event. However, there was an interaction between amount of SEM consumed and percentage of bareback SEM consumed on both outcomes, such that men who reported both a high frequency of SEM consumption and a high percentage of their SEM being bareback reported the highest levels of risk behavior. These findings highlight the role that barebacking depicted in SEM may play in the normalization of sexual risk behaviors for GBM. Interventions looking to target the role SEM may play in the lives of GBM should examine what variables may help to mediate associations between viewing SEM and engaging in risk behavior.

Viewing Sexually Explicit Media and Its Association with Mental Health Among Gay and Bisexual Men Across the U.S.

Gay and bisexual men (GBM) have reported viewing significantly more sexually explicit media (SEM) than heterosexual men. There is evidence that viewing greater amounts of SEM may result in more negative body attitude and negative affect. However, no studies have examined these variables within the same model. A national sample of 1071 HIV-negative GBM in the U.S. participating in a larger study completed an online survey, which included measures of SEM consumption, male body attitudes, anxiety, and depression. Participants reported viewing 3 h of SEM per week, on average, and 96% of participants reported recently viewing at least some SEM. Greater consumption of SEM was directly related to more negative body attitude and both depressive and anxious symptomology. There was also a significant indirect effect of SEM consumption on depressive and anxious symptomology through body attitude. These findings highlight the relevance of both SEM on body image and negative affect along with the role body image plays in anxiety and depression outcomes for GBM. They also indicate a potential role for body image in explaining the co-occurrence of SEM consumption and negative affect. For interventions looking to alleviate negative affect for GBM, it may be important to address SEM consumption and body image as they are shown to be associated with both anxious and depressive symptomology.

Familiarity with and Preferences for Oral and Long-Acting Injectable HIV Pre-exposure Prophylaxis (PrEP) in a National Sample of Gay and Bisexual Men in the U.S.

We sought to determine preferences for oral versus long-acting injectable (LAI) PrEP among gay and bisexual men (GBM). We surveyed a national U.S. sample of 1071 GBM about forms of PrEP. LAI PrEP was found to be acceptable among 43.2 % of men when injected monthly compared with 53.6 % of men when injected every 3 months. When asked to choose between forms of PrEP, 46.0 % preferred LAI, 14.3 % oral, 21.7 % whichever was most effective, 10.1 % had no preference, and 7.8 % would not take PrEP. There were no differences in PrEP preferences by race/ethnicity, income, region of residence, or relationship status. Those unwilling to take PrEP were significantly older than those who preferred LAI PrEP and those who would take either. Those who preferred the most effective form were younger, had less education, and reported more recent club drug use. Those who reported condomless anal sex and those who thought they were good PrEP candidates were more willing to take PrEP. Long-term health and side effects were of the greatest concern for both LAI and oral PrEP. The availability of LAI PrEP has the potential to increase uptake among GBM. The results of ongoing clinical trials of LAI PrEP will need to demonstrate similar or greater efficacy as daily Truvada for uptake to be maximized.

Willingness to Take PrEP and Potential for Risk Compensation Among Highly Sexually Active Gay and Bisexual Men.

Once-daily Truvada (Emtricitabine/Tenofovir) as a method of pre-exposure prophylaxis (PrEP) is one of the most promising biomedical interventions to eliminate new HIV infections; however, uptake among gay, bisexual, and other men who have sex with men has been slow amidst growing concern in popular/social media that PrEP use will result in reduced condom use (i.e., risk compensation). We investigated demographic, behavioral, and psychosocial differences in willingness to use PrEP as well as the perceived impact of PrEP on participants' condom use in a sample of 206 highly sexually active HIV-negative gay and bisexual men. Nearly half (46.1 %) said they would be willing to take PrEP if it were provided at no cost. Although men willing to take PrEP (vs. others) reported similar numbers of recent casual male partners (<6 weeks), they had higher odds of recent receptive condomless anal sex (CAS)-i.e., those already at high risk of contracting HIV were more willing to take PrEP. Neither age, race/ethnicity, nor income were associated with willingness to take PrEP, suggesting equal acceptability among subpopulations that are experiencing disparities in HIV incidence. There was limited evidence to suggest men would risk compensate. Only 10 % of men who had not engaged in recent CAS felt that PrEP would result in them starting to have CAS. Men who had not tested for HIV recently were also significantly more likely than others to indicate willingness to take PrEP. Offering PrEP to men who test infrequently may serve to engage them more in routine HIV/STI testing and create a continued dialogue around sexual health between patient and provider in order to prevent HIV infection.

Histoplasma capsulatum as a cause for prolonged pulmonary illness in an immunocompetent returning traveller from Bangladesh.

Fungal infections can be challenging to diagnose in returning travellers due to their non-specific clinical manifestations and changing epidemiology. We present a case of progressive disseminated histoplasmosis in a returning traveller from Bangladesh. The patient had a progressive and prolonged respiratory illness necessitating mechanical ventilatory support. The clue to potential fungal aetiology was provided by serum fungal markers - 1-3-ß-D-glucan and Aspergillus galactomannan. Diagnosis was eventually made using panfungal PCR on bronchioalveolar lavage fluid.

The influence of different lipid environments on the structure and function of the hepatitis C virus p7 ion channel protein.

Abstract The hepatitis C virus (HCV) encodes the p7 protein that oligomerizes to form an ion channel. The 63 amino acid long p7 monomer is an integral membrane protein predominantly found in the endoplasmic reticulum (ER). Although it is currently unknown whether p7 is incorporated into secreted virions, its presence is crucial for the release of infectious virus. The molecular and biophysical mechanism employed by the p7 ion channel is largely unknown, but in vivo it is likely to be embedded in membranes undergoing changes in lipid composition. In this study we analyze the influence of the lipid environment on p7 ion channel structure and function using electrophysiology and synchrotron radiation circular dichroism (SRCD) spectroscopy. We incorporated chemically synthesized p7 polypeptides into artificial planar membranes of various lipid compositions. A lipid bilayer composition comprising phosphatidylcholine (PC) and phosphatidylethanolamine (PE) (4:1 PC:PE) led to burst-like patterns in the channel recordings with channel openings lasting up to 0.5 s. The reverse ratio of PC:PE (1:4) gave rise to individual channels continuously opening for up to 8 s. SRCD spectroscopy of p7 embedded into liposomes of corresponding lipid compositions suggests there is a structural effect of the lipid composition on the p7 protein.

Real-world SARS CoV-2 testing in Northern England during the first wave of the COVID-19 pandemic.

OBJECTIVES: SARS-CoV-2 emerged in South Asia in 2019 and has resulted in a global pandemic. Public Health England (PHE) Manchester rapidly escalated testing for SARS-CoV-2 in the highest COVID-19 incidence location in England. The results of the PHE Manchester SARS-CoV-2 surveillance during the first wave are presented. METHODS: Retrospective data were collected for patients fitting the PHE SARS-CoV-2 case definition from 11th February to 31st August 2020. Respiratory tract, tissue, faecal, fluid and cerebrospinal (CSF) samples were tested for SARS-CoV-2 by a semi-quantitative real-time reverse-transcription PCR. RESULTS: Of the 204,083 tests for SARS-CoV-2, 18,011 were positive demonstrating a positivity of 8.90%. Highest positivity was in nasal swabs (20.99%) followed by broncheo-alveolar lavage samples (12.50%). None of the faecal, fluid or CSF samples received were positive for SARS-CoV-2. CONCLUSIONS: There was a high incidence of SARS-CoV-2 patients in the North-West of England during the first UK wave of the Covid-19 pandemic. Highest positivity rate was in nasal specimens suggesting this is the optimum sample type within this dataset for detecting SARS-CoV-2. Further studies are warranted to assess the utility of testing faecal, fluid and CSF samples. Rapid escalation of testing via multiple platforms was required to ensure prompt diagnosis and isolate infected cases to reduce transmission of the virus.

Protocol for DexEnceph: a randomised controlled trial of dexamethasone therapy in adults with herpes simplex virus encephalitis.

INTRODUCTION: Herpes simplex virus (HSV) encephalitis is a rare severe form of brain inflammation that commonly leaves survivors and their families with devastating long-term consequences. The virus particularly targets the temporal lobe of the brain causing debilitating problems in memory, especially verbal memory. It is postulated that immunomodulation with the corticosteroid, dexamethasone, could improve outcomes by reducing brain swelling. However, there are concerns (so far not observed) that such immunosuppression might facilitate increased viral replication with resultant worsening of disease. A previous trail closed early because of slow recruitment. METHOD: DexEnceph is a pragmatic multicentre, randomised, controlled, open-label, observer-blind trial to determine whether adults with HSV encephalitis who receive dexamethasone alongside standard antiviral treatment with aciclovir for have improved clinical outcomes compared with those who receive standard treatment alone. Overall, 90 patients with HSV encephalitis are being recruited from a target of 45 recruiting sites; patients are randomised 1:1 to the dexamethasone or control arms of the study. The primary outcome measured is verbal memory as assessed by the Weschler Memory Scale fourth edition Auditory Memory Index at 26 weeks after randomisation. Secondary outcomes are measured up to 72 weeks include additional neuropsychological, clinical and functional outcomes as well as comparison of neuroimaging findings. Patient safety monitoring occurs throughout and includes the detection of HSV DNA in cerebrospinal fluid 2 weeks after randomisation, which is indicative of ongoing viral replication. Innovative methods are being used to ensure recrutiment targets are met for this rare disease. DISCUSSION: DexEnceph aims to be the first completed randomised controlled trial of corticosteroid therapy in HSV encephalitis. The results will provide evidence for future practice in managing adults with the condition and has the potential to improve outcomes . ETHICS AND DISSEMINATION: The trial has ethical approval from the UK National Research Ethics Committee (Liverpool Central, REF: 15/NW/0545, 10 August 2015). Protocol V.2.1, July 2019. The results will be published and presented as soon as possible on completion. TRIAL REGISTRATION NUMBERS: ISRCTN11774734, EUDRACT 2015-001609-16.

The Impact of Pre-Exposure Prophylaxis (PrEP) Use on Sexual Anxiety, Satisfaction, and Esteem Among Gay and Bisexual Men.

Gay and bisexual men (GBM) with heightened fears of human immunodeficiency virus (HIV) acquisition have reported high levels of sexual anxiety and low sexual self-esteem. Similarly, sexual satisfaction has been reported to be lower among some GBM who rely solely on condom use as HIV prevention. We sought to explore whether pre-exposure prophylaxis (PrEP) had an impact on the sexual satisfaction, anxiety, and esteem of GBM. As part of a longitudinal cohort study of 1,071 GBM, participants reported at three time points on PrEP use and completed the Multidimensional Sexual Self-Concept Questionnaire (MSSCQ). A total of 137 GBM began taking PrEP in the 24 months following baseline. Comparing their responses during times before initiating PrEP and after, within adjusted multilevel models, there was a significant decrease in sexual anxiety (B = -0.27, p = 0.03) but no significant changes in sexual esteem or satisfaction. Our findings indicate important psychological improvements resulting from PrEP initiation. Further research should explore the potential for other psychological benefits of PrEP use among GBM.

How Do Gay and Bisexual Men Make Up for Missed PrEP Doses, and What Impact Does Missing a Dose Have on Their Subsequent Sexual Behavior?

HIV pre-exposure prophylaxis (PrEP) is being adopted by members of key populations, such as gay and bisexual men (GBM). Since adherence to a daily PrEP regimen ensures a maximum protection, it is critical to understand GBM's behavioral responses to having missed PrEP doses. We report on qualitative interviews with GBM taking PrEP. We identified three behavioral responses: (1) 59% continued with their next scheduled dose; (2) 49% described "making up" for a missed dose by taking medication as soon as possible; and (3) 11% reported "doubling" the next PrEP dose. Participants provided potentially contradictory narratives about their sexual behavior after a missed dose: (1) 54% described making no changes; (2) 49% described adjusting their sexual behavior to reduce HIV risk; and (3) 10% said their decision would be contingent upon how many doses were missed. For PrEP prescribers, our data provide a useful lens to understand patients' lived experiences with PrEP.

Retrospective analysis of the associations and effectiveness of performing therapeutic drug monitoring in pregnant HIV-positive women in two large centres in Manchester.

There is no proven benefit for the routine use of therapeutic drug monitoring in HIV-positive pregnant women either for improving viral control or preventing mother-to-child transmission. This analysis reviewed a cohort of 171 HIV-positive pregnant women delivering between 1 January 2008 and 28 May 2013 to first establish which baseline characteristics are associated with having therapeutic drug monitoring performed, and whether therapeutic drug monitoring was associated with improved HIV control during pregnancy or mother-to-child transmission. Therapeutic drug monitoring was performed in 39% ( n = 66) of patients; it was associated with baseline characteristics of poor adherence to therapy (therapeutic drug monitoring 23% versus non-therapeutic drug monitoring 10%, p = 0.025) and the use of protease inhibitors (therapeutic drug monitoring 94% versus non-therapeutic drug monitoring 77%, p = 0.005). By multivariate analysis therapeutic drug monitoring was associated with medication alterations during pregnancy (therapeutic drug monitoring 68% versus non-therapeutic drug monitoring 12%, p = < 0.001), but not associated with any difference in viral load breakthrough during pregnancy (therapeutic drug monitoring 12% versus non-therapeutic drug monitoring 7%, p = 0.456) and viral load detectable at birth (therapeutic drug monitoring 14% versus non-therapeutic drug monitoring 9%, p = 0.503). There were no instances of mother-to-child transmission. Therapeutic drug monitoring's association with medication changes is postulated as partially causal in this cohort. There was no evidence of any association with improved control or reduced transmission of HIV to advocate routine therapeutic drug monitoring use.

Distinguishing hypothetical willingness from behavioral intentions to initiate HIV pre-exposure prophylaxis (PrEP): Findings from a large cohort of gay and bisexual men in the U.S.

RATIONALE: Much of the data on the acceptability of HIV Pre-Exposure Prophylaxis (PrEP) is based on willingness to take PrEP (i.e., hypothetical receptivity) rather than actual intentions (i.e., planned behavioral action) to do so. OBJECTIVE: We sought to examine differences between hypothetical willingness and behavioral intentions to begin PrEP in a national sample of gay and bisexual men (GBM) across the U.S. METHODS: We utilized data collected in 2015 to examine differences between those Unwilling (42.6% n = 375), Willing but not intending (41.4%, n = 365), and willing and Intending to take PrEP (15.9%, n = 140) in a multivariable, multinomial logistic regression. RESULTS: Men with less education had higher odds of Intending to take PrEP. Compared to men unsure about PrEP's efficacy, those who believed PrEP was at least 90% efficacious had higher odds of Intending to take PrEP. Those who saw themselves as appropriate candidates for PrEP had higher odds of Intending to take PrEP while those who saw themselves as inappropriate candidates for PrEP had lower odds of Intending to take PrEP in comparison to men unsure if they were appropriate candidates. Increased motivation for condom non-use because of perceived sexual pressure by partners was associated with higher odds of Intending to take PrEP. The groups did not differ by risk behavior nor recent STI diagnosis. CONCLUSIONS: Overall, the distinction between willingness and intentions to take PrEP was meaningful and may help explain disparities between PrEP acceptability and uptake. While much of the literature has focused on hypothetical willingness to take PrEP, these results highlight the importance of simultaneously assessing willingness and intentions when examining correspondence with uptake and developing interventions to increase PrEP uptake.

Uptake of HIV Pre-Exposure Prophylaxis (PrEP) in a National Cohort of Gay and Bisexual Men in the United States.

OBJECTIVES: The HIV care cascade provides milestones to track the progress of HIV-positive people from seroconversion through viral suppression. We propose a Motivational pre-exposure prophylaxis (PrEP) Cascade involving 5 stages based on the Transtheoretical Model of Change. METHODS: We analyzed data from 995 men in One Thousand Strong, a longitudinal study of a national panel of HIV-negative gay and bisexual men in the United States. RESULTS: Nearly all (89%) participants were sexually active in the past 3 months and 65% met Centers for Disease Control criteria for PrEP candidacy. Of those identified as appropriate candidates, 53% were Precontemplative (stage 1; unwilling to take or believing they were inappropriate candidates for PrEP) and 23% were in Contemplation (stage 2; willing and self-identified as appropriate candidates). Only 11% were in PrEParation (stage 3; seeing PrEP as accessible and planning to initiate PrEP) and 4% were in PrEP Action (stage 4; prescribed PrEP). Although few of those who were identified as appropriate candidates were on PrEP, nearly all PrEP users (98%) reported adhering to 4 or more doses per week and most (72%) were returning for recommended quarterly medical visits, resulting in 9% of PrEP candidates reaching Maintenance and Adherence (stage 5). CONCLUSIONS: The large majority of participants were appropriate candidates for PrEP, yet fewer than 1 in 10 were using and adherent to PrEP. These findings highlight the need for interventions tailored to address the unique barriers men face at each stage of the cascade, particularly at the earliest stages where the most dramatic losses were identified.

Profile of cabotegravir and its potential in the treatment and prevention of HIV-1 infection: evidence to date.

Modern antiretroviral therapy has demonstrated effectiveness in preexposure prophylaxis (PrEP) and treatment of HIV infection. There is a demand for prevention and treatment regimens that could overcome challenges of improving adherence, toxicity, and dosing convenience. Cabotegravir is an integrase strand transfer inhibitor and an analog of dolutegravir. Unlike dolutegravir, cabotegravir has a long half-life and can be formulated into a long-acting nanosuspension for parenteral administration. Initial pharmokinetic studies in humans have demonstrated adequate drug levels with intramuscular (IM) administration at 4 weekly and 8 weekly intervals, with few interactions with commonly used concomitant medications. Preliminary animal PrEP studies have shown that IM cabotegravir can prevent simian/HIV acquisition from rectal, vaginal, and intravenous challenge. Currently, there are two ongoing Phase II studies assessing cabotegravir as a PrEP agent in humans: ÉCLAIR and HPTN077. Cabotegravir has been studied in combination with rilpivirine as long-acting IM maintenance therapy. The Long-Acting Antiretroviral Treatment Enabling study demonstrated that those switching to oral cabotegravir/rilpivirine once virologically suppressed were more likely to maintain suppression than those continuing standard efavirenz-based therapy (82% vs 71% at 24 weeks). Initial results of the Long-Acting Antiretroviral Treatment Enabling-2 study of parenteral regimens found that 12 weeks after randomization to parenteral or oral regimens, there was no difference in proportions virologically suppressed on cabotegravir/rilpivirine daily orally vs IM every 4 weeks or 8 weeks (91% vs 94% vs 95%). The injections were well tolerated as, although they caused injection site pain in most recipients, most participants reported satisfaction with parenteral therapy. Cabotegravir offers a new member of the integrase strand transfer inhibitor class with potential for alternative mode of delivery. We await Phase III studies to define its efficacy and real-world experience to learn which patient groups stand to benefit most from the novel mode of delivery of treatment and PrEP.
