Changing the Use of HIV Pre-exposure Prophylaxis Among Men Who Have Sex With Men During the COVID-19 Pandemic in Melbourne, Australia

Sexual healthcare professionals' views on the rapid provision of remote services at the beginning of COVID-19 pandemic: A mixed-methods study

Introduction: The COVID-19 pandemic and social distancing measures forced sexual health services to engage with patients remotely. We aimed to understand perceived barriers and facilitators to the provision of digital sexual health services during the first months of the pandemic. Methods: An online survey and qualitative interviews with UK sexual healthcare professionals recruited online and via snowball sampling were conducted in May–July 2020. Results: Amongst 177 respondents (72% female, 86% White, mean age = 46, SD = 9), most utilised telephone and email as their main communication channels; however, their perceived effectiveness varied (94% and 66%, respectively). Most agreed that staff needed additional training (89%), the available technology was not adequate (66%) and health professionals were hesitant to provide online consultations (46%). They had positive attitudes towards digitalisation, improving service quality and cost-effectiveness but were concerned about exacerbating health inequalities. Discussion: The study identifies a need for clear guidelines and training around the use of digital tools as well as a demand for investment in hardware and software required for the provision of remote services. Future research needs to explore the acceptability, safety and effectiveness of various digital tools to narrow health inequalities in sexual health service users.

The silent epidemic of lymphogranuloma venereum inside the COVID-19 pandemic in Madrid, Spain, March 2020 to February 2021

Despite social distancing measures implemented in Madrid to prevent the propagation of SARS-CoV-2, a significant increase (57.1%; 28.5 to 38.5 cases/month) in cases of lymphogranuloma venereum was detected during the COVID-19 pandemic. This unusual scenario might have accelerated a shift in Chlamydia trachomatis (CT) epidemiology towards a higher proportion of L genotypes compared with non-L genotypes in CT-positive samples. Our data underscore the importance of surveillance of sexually transmitted infections during the pandemic, in particular among vulnerable populations.

Imperfect adherence in real life: a prevention-effective perspective on adherence to daily and event-driven HIV pre-exposure prophylaxis among men who have sex with men - a prospective cohort study in Taiwan

INTRODUCTION

Both daily and event-driven (ED) pre-exposure prophylaxis (PrEP) have been demonstrated to be highly effective among men who have sex with men (MSM). Prevention-effective adherence proposes that PrEP adherence should be aligned with the risk of HIV, which could be applied to both daily and ED PrEP adherence measurement. The objective of this study was to describe the relationship between the use of PrEP and sex events among the MSM PrEP users and identify factors associated with adherence among daily and ED MSM PrEP users.

METHODS

A multicentre, observational, prospective cohort study was conducted at three hospital-based clinics in three urban cities of Taiwan from January 2018 to December 2019. MSM ages 18 years or older - at high risk of HIV acquisition and taking PrEP during the study period - were included in the analysis. MSM PrEP users were allowed to choose between daily and ED PrEP based on their preference. Data on sociodemographic characteristics, mental health, sexual behaviours, substance use and PrEP-taking behaviours were collected at each visit.

RESULTS

A total of 374 MSM were included in the analysis with 1,054 visits. More than half (56%) of the PrEP users chose ED at the baseline and 150 regimen switches were reported by 21% of the participants. There was only one seroconversion documented during the study period. Most (84.2%) of the MSM PrEP users were able to adhere to PrEP during the most recent anal intercourse in the past one month. Among ED PrEP users with suboptimal adherence, the majority (81.9%) missed the pre-coital dose. In the multivariable analysis, we found that participants who switched from daily to an ED dosing regimen were associated with poorer adherence to PrEP.

CONCLUSIONS

A high level of PrEP adherence was observed among the majority of MSM in a real-world setting. On the other hand, Taiwanese MSM switching from daily to ED dosing regimens were less likely to adhere to PrEP, suggesting that novel approaches focusing on a dosing switch would be necessary for MSM to improve their adherence to PrEP.

Effects of the COVID-19 pandemic on the sexual and mental health of adolescent and adult men who have sex with men and transgender women participating in two PrEP cohort studies in Brazil: COBra study protocol

INTRODUCTION

The COVID-19 pandemic and its control measures have impacted health and healthcare provision in various levels. Physical distancing measures, for instance, may affect sexual health, impacting access to HIV prevention supplies and changing sexual behaviour, as well as mental health, increasing feelings of unsafety and weakening community support ties. These effects can be worsened among socially marginalised groups, such as men who have sex with men (MSM) and transgender women (TGW). Brazil is among the countries most affected by COVID-19 in the world, where control measures have been inconsistently implemented. We aim to investigate the effects of the COVID-19 pandemic on the sexual and mental health of adolescent and adult MSM and TGW in Brazil.

METHODS

Convergent mixed-method prospective cohort study, nested in two ongoing HIV pre-exposure prophylaxis (PrEP) cohorts in Brazil, named PrEP1519 and Combina. Participants will be invited to answer, at baseline and after 6 months, a questionnaire about the effects of the COVID-19 pandemic on sexual behaviour, HIV prevention and mental health. Data on HIV infection and sexually transmitted infections (STI) will be collected as part of routine follow-up from the cohorts. Main outcome measures (HIV infection, STI and depression symptoms) will be observed within 12 months after baseline. Sample size is estimated at 426 participants. Complementarily, 50 participants will be invited to in-depth interviews through video calls or interactive voice response, and 20 will be invited to chronicle their lives during the pandemic through digital diaries. Triangulation will be done across qualitative methods and with the quantitative data.

ETHICS AND DISSEMINATION

The study was approved by Research Ethics Committees from the Brazilian Universities coordinating the study. Findings will be published in scientific journals and presented at meetings. Informative flyers will be elaborated to communicate study findings to participants and key stakeholders.

The potential effect of COVID-19-related disruptions on HIV incidence and HIV-related mortality among men who have sex with men in the USA: a modelling study

BACKGROUND

During the COVID-19 pandemic, men who have sex with men (MSM) in the USA have reported similar or fewer sexual partners and reduced HIV testing and care access compared with before the pandemic. Pre-exposure prophylaxis (PrEP) use has also declined. We aimed to quantify the potential effect of COVID-19 on HIV incidence and HIV-related mortality among US MSM.

METHODS

We used a calibrated, deterministic, compartmental HIV transmission model for MSM in Baltimore (MD, USA) and available data on COVID-19-related disruptions to HIV services to predict effects of reductions in sexual partners (0%, 25%, 50%), condom use (5%), HIV testing (20%), viral suppression (10%), PrEP initiations (72%), PrEP adherence (9%), and antiretroviral therapy (ART) initiations (50%). In our main analysis, we modelled disruptions due to COVID-19 starting Jan 1, 2020, and lasting 6 months. We estimated the median change in cumulative new HIV infections and HIV-related deaths among MSM over 1 and 5 years, compared with a base case scenario without COVID-19-related disruptions.

FINDINGS

A 25% reduction in sexual partners for 6 months among MSM in Baltimore, without HIV service changes, could reduce new HIV infections by median 12·2% (95% credible interval 11·7 to 12·8) over 1 year and median 3·0% (2·6 to 3·4) over 5 years. In the absence of changes in sexual behaviour, the 6-month estimated reductions in condom use, HIV testing, viral suppression, PrEP initiations, PrEP adherence, and ART initiations combined are predicted to increase new HIV infections by median 10·5% (5·8 to 16·5) over 1 year, and by median 3·5% (2·1 to 5·4) over 5 years. Disruptions to ART initiations and viral suppression are estimated to substantially increase HIV-related deaths (ART initiations by median 1·7% [0·8 to 3·2], viral suppression by median 9·5% [5·2 to 15·9]) over 1 year, with smaller proportional increases over 5 years. The other individual disruptions (to HIV testing, PrEP and condom use, PrEP initiation, and partner numbers) were estimated to have little effect on HIV-related deaths (<1% change over 1 or 5 years). A 25% reduction in sexual partnerships is estimated to offset the effect of the combined service disruptions on new HIV infections (change over 1 year: median -3·9% [-7·4 to 1·0]; over 5 years: median 0·0% [-0·9 to 1·4]), but not on HIV deaths (change over 1 year: 11·0% [6·2 to 17·7]; over 5 years: 2·6% [1·5 to 4·3]).

INTERPRETATION

Maintaining access to ART and adherence support is of the utmost importance to maintain viral suppression and minimise excess HIV-related mortality due to COVID-19 restrictions in the USA, even if disruptions to services are accompanied by reductions in sexual partnerships.

Brief Report: Changes in PrEP Use, Sexual Practice, and Use of Face Mask During Sex Among MSM During the Second Wave of COVID-19 in Melbourne, Australia

BACKGROUND

A second wave of COVID-19 began in late June in Victoria, Australia. Stage 3 then Stage 4 restrictions were introduced in July-August. This study aimed to compare the use of pre-exposure prophylaxis (PrEP) and sexual practices among men who have sex with men taking PrEP between May-June (post-first lockdown) and July-August (second lockdown).

METHODS

This was an online survey conducted among men who have sex with men who had their PrEP managed at the Melbourne Sexual Health Centre, Australia. A short message service with a link to the survey was sent to 503 PrEP clients who provided consent to receive a short message service from Melbourne Sexual Health Centre in August 2020.

RESULTS

Of the 192 participants completed the survey, 153 (80%) did not change how they took PrEP. Of the 136 daily PrEP users, 111 (82%) continued to take daily PrEP, 3 (2%) switched to on-demand PrEP, and 22 (16%) stopped PrEP in July-August. Men generally reported that they had no partners or decreased sexual activities during second lockdown compared with post-first lockdown; the number of casual sex partners (43% decreased vs. 3% increased) and the number of kissing partners (36% decreased vs. 3% increased). Most men reported no chemsex (79%) or group sex (77%) in May-August. 10% (13/127) of men had ever worn face masks during sex in May-August.

CONCLUSION

During the second wave of COVID-19 in Victoria, most men did not change the way they used PrEP but the majority had no risks or reduced sexual practices while one in 10 men wore a face mask during sex.

The interplay between HIV and COVID-19: summary of the data and responses to date

PURPOSE OF REVIEW

We examine the interplay between the HIV and COVID-19 epidemics, including the impact of HIV on COVID-19 susceptibility and severe disease, the effect of the COVID-19 epidemic on HIV prevention and treatment, and the influence of the HIV epidemic on responses to COVID-19.

RECENT FINDINGS

Evidence to date does not suggest that people living with HIV (PLWH) have a markedly higher susceptibility to SARS-CoV-2 infection, with disparities in the social determinants of health and comorbidities likely having a greater influence. The majority of literature has not supported a higher risk for severe disease among PLWH in Europe and the United States, although a large, population-based study in South Africa reported a higher rate of death due to COVID-19. Higher rates of comorbidities associated with COVID-19 disease severity among PLWH is an urgent concern. COVID-19 is leading to decreased access to HIV prevention services and HIV testing, and worsening HIV treatment access and virologic suppression, which could lead to worsening HIV epidemic control.

CONCLUSION

COVID-19 is threatening gains against the HIV epidemic, including the U.S. Ending the HIV Epidemic goals. The ongoing collision of these two global pandemics will continue to need both study and interventions to mitigate the effects of COVID-19 on HIV efforts worldwide.

Substantial Decline in Use of HIV Preexposure Prophylaxis Following Introduction of COVID-19 Physical Distancing Restrictions in Australia: Results From a Prospective Observational Study of Gay and Bisexual Men

BACKGROUND

In response to the novel coronavirus disease (COVID-19) pandemic, Australia introduced public health and physical distancing restrictions in late March 2020. We investigated the impact of these restrictions on HIV preexposure prophylaxis (PrEP) use among Australian gay and bisexual men (GBM).

METHODS

Participants in an ongoing online cohort study previously reported PrEP use from 2014 to 2019. In April 2020, 847 HIV-negative and untested participants completed questionnaires assessing changes in PrEP use as a result of COVID-19 public health measures. Binary logistic multiple regression was used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) to compare changes in PrEP use behaviors.

RESULTS

Among 847 men, mean age was 44.1 years (SD: 12.7). PrEP use rose from 4.9% in 2015 to 47.2% in 2020. Among those, 41.8% (n = 167) discontinued PrEP use during COVID-19 restrictions. Discontinuing PrEP during COVID-19 restrictions was independently associated with being less likely to have recently tested for HIV (aOR: 0.17; 95% CI: 0.09 to 0.34; P < 0.001) and less likely to report sex with casual partners (aOR: 0.28; 95% CI: 0.14 to 0.54; P < 0.001).

CONCLUSIONS

By April 2020, following the introduction of COVID-19 restrictions, GBM dramatically reduced PrEP use, coinciding with a reduction in sexual activity. Longer-term impacts of COVID-19 restrictions on sexual behaviors among GBM need to be monitored because they may foreshadow fluctuations in prevention coverage and risk of HIV infection. Our findings indicate a potential need for clear, targeted information about resumption of PrEP and on-demand optimal dosing regimens in response to ongoing changes in restrictions.

Travel restrictions and lockdown during the COVID-19 pandemic-impact on notified infectious diseases in Switzerland

Based on notification data the impact of the COVID-19 lockdown in Switzerland was assessed. While the incidence of tick-borne encephalitis almost doubled as compared to 2016-2019, a reduction in all other infectious diseases was recorded. The lowest reduction rates (<25%) were noted for legionellosis, hepatitis A, chlamydia infection and gonorrhoea.

Estimating the potential impact of COVID-19-related disruptions on HIV incidence and mortality among men who have sex with men in the United States: a modelling study

BACKGROUND

During the COVID-19 pandemic, gay and other men who have sex with men (MSM) in the United States (US) report similar or fewer sexual partners and reduced HIV testing and care access. Pre-exposure prophylaxis (PrEP) use has declined. We estimated the potential impact of COVID-19 on HIV incidence and mortality among US MSM.

METHODS

We used a calibrated HIV transmission model for MSM in Baltimore, Maryland, and available data on COVID-19-related disruptions to predict impacts of data-driven reductions in sexual partners(0%,25%,50%), condom use(5%), HIV testing(20%), viral suppression(10%), PrEP initiations(72%), PrEP use(9%) and ART initiations(50%), exploring different disruption durations and magnitudes. We estimated the median (95% credible interval) change in cumulative new HIV infections and deaths among MSM over one and five years, compared with a scenario without COVID-19-related disruptions.

FINDINGS

A six-month 25% reduction in sexual partners among Baltimore MSM, without HIV service changes, could reduce new HIV infections by 12·2%(11·7,12·8%) and 3·0%(2·6,3·4%) over one and five years, respectively. In the absence of changes in sexual behaviour, the six-month data-driven disruptions to condom use, testing, viral suppression, PrEP initiations, PrEP use and ART initiations combined were predicted to increase new HIV infections by 10·5%(5·8,16·5%) over one year, and by 3·5%(2·1,5·4%) over five years. A 25% reduction in partnerships offsets the negative impact of these combined service disruptions on new HIV infections (overall reduction 3·9%(-1·0,7·4%), 0·0%(-1·4,0·9%) over one, five years, respectively), but not on HIV deaths (corresponding increases 11·0%(6·2,17·7%), 2·6%(1·5,4·3%)). The predicted impacts of reductions in partnerships or viral suppression doubled if they lasted 12 months or if disruptions were twice as large.

INTERPRETATION

Maintaining access to ART and adherence support is of the utmost importance to minimise excess HIV-related mortality due to COVID-19 restrictions in the US, even if accompanied by reductions in sexual partnerships.

RESEARCH IN CONTEXT

Evidence before this study: The COVID-19 pandemic and responses to it have disrupted HIV prevention and treatment services and led to changes in sexual risk behaviour in the United States, but the overall potential impact on HIV transmission and HIV-related mortality is not known. We searched PubMed for articles documenting COVID-related disruptions to HIV prevention and treatment and changes in sexual risk behaviour in the United States, published between 1 st January and 7 th October 2020, with no language restrictions, using the terms COVID* AND (HIV OR AIDS) AND ("United States" OR US). We identified three cross-sectional surveys assessing changes in sexual risk behaviour among men who have sex with men (MSM) in the United States, one finding a reduction, one a slight increase, and one no change in partner numbers during COVID-19 restrictions. Two of these studies also found reductions in reported HIV testing, HIV care and/or access to pre-exposure prophylaxis (PrEP) among MSM due to COVID-19. A separate study from a San Francisco clinic found declines in viral suppression among its clients during lockdown. We searched PubMed for articles estimating the impact of COVID-related disruptions on HIV transmission and mortality published between 1 st January 2020 and 12 th October 2020, with no language restrictions, using the following terms: COVID* AND model* AND (HIV OR AIDS). We identified two published studies which had used mathematical modelling to estimate the impact of hypothetical COVID-19-related disruptions to HIV programmes on HIV-related deaths and/or new HIV infections in Africa, another published study using modelling to estimate the impact of COVID-19-related disruptions and linked HIV and SARS-CoV-2 testing on new HIV infections in six cities in the United States, and a pre-print reporting modelling of the impact of COVID-19-related disruptions on HIV incidence among men who have sex with men in Atlanta, United States. None of these studies were informed by data on the size of these disruptions. The two African studies and the Atlanta study assessed the impact of disruptions to different healthcare disruptions separately, and all found that the greatest negative impacts on new HIV infections and/or deaths would arise from interruptions to antiretroviral therapy. They all found smaller effects on HIV-related mortality and/or incidence from other healthcare disruptions, including HIV testing, PrEP use and condom supplies. The United States study assessing the impact of linked HIV and SARS-CoV-2 testing estimated that this could substantially reduce HIV incidence. Added value of this study: We used mathematical modelling to derive estimates of the potential impact of the COVID-19 pandemic and associated restrictions on HIV incidence and mortality among MSM in the United States, directly informed by data from the United States on disruptions to HIV testing, antiretroviral therapy and pre-exposure prophylaxis services and reported changes in sexual risk behaviour during the COVID-19 pandemic. We also assessed the impact of an HIV testing campaign during COVID-19 lockdown.Implications of all the available evidence: In the United States, maintaining access to antiretroviral therapy and adherence support for both existing and new users will be crucial to minimize excess HIV-related deaths arising from the COVID-19 pandemic among men who have sex with men. While reductions in sexual risk behaviour may offset increases in new HIV infections arising from disruptions to HIV prevention and treatment services, this will not offset the additional HIV-related deaths which are also predicted to occur. There are mixed findings on the impact of an HIV testing campaign among US MSM during COVID-19 lockdown. Together, these studies highlight the importance of maintaining effective HIV treatment provision during the COVID-19 pandemic.

Sexually Transmitted Infection Diagnoses and Access to a Sexual Health Service Before and After the National Lockdown for COVID-19 in Melbourne, Australia

Background

We aimed to examine the impact of lockdown on sexually transmitted infection (STI) diagnoses and access to a public sexual health service during the coronavirus disease 2019 (COVID-19) pandemic in Melbourne, Australia.

Methods

The operating hours of Melbourne Sexual Health Centre (MSHC) remained the same during the lockdown. We examined the number of consultations and STIs at MSHC between January and June 2020 and stratified the data into prelockdown (February 3 to March 22), lockdown (March 23 to May 10), and postlockdown (May 11 to June 28), with 7 weeks in each period. Incidence rate ratios (IRRs) and their 95% confidence intervals (CI) were estimated using Poisson regression models.

Results

The total number of consultations dropped from 7818 in prelockdown to 4652 during lockdown (IRR, 0.60; 95% CI, 0.57-0.62) but increased to 5347 in the postlockdown period (IRR, 1.15; 95% CI, 1.11-1.20). There was a 68% reduction in asymptomatic screening during lockdown (IRR, 0.32; 95% CI, 0.30-0.35), but it gradually increased during the postlockdown period (IRR, 1.59; 95% CI, 1.46-1.74). Conditions with milder symptoms showed a marked reduction, including nongonococcal urethritis (IRR, 0.60; 95% CI, 0.51-0.72) and candidiasis (IRR, 0.61; 95% CI, 0.49-0.76), during lockdown compared with prelockdown. STIs with more marked symptoms did not change significantly, including pelvic inflammatory disease (IRR, 0.95; 95% CI, 0.61-1.47) and infectious syphilis (IRR, 1.14; 95% CI, 0.73-1.77). There was no significant change in STI diagnoses during postlockdown compared with lockdown.

Conclusions

The public appeared to be prioritizing their attendance for sexual health services based on the urgency of their clinical conditions. This suggests that the effectiveness of clinical services in detecting, treating, and preventing onward transmission of important symptomatic conditions is being mainly preserved despite large falls in absolute numbers of attendees.

Changing from Clinician-Collected to Self-Collected Throat Swabs for Oropharyngeal Gonorrhea and Chlamydia Screening among Men Who Have Sex with Men

The coronavirus disease 2019 (COVID-19) pandemic has led many clinics to move from clinician-collected to self-collected oropharyngeal swabs for the detection of sexually transmitted infections (STIs). Before this change, however, self-collection was used primarily for genital and anorectal infections, with only limited studies on the performance of self-collection of oropharyngeal swabs for oropharyngeal STI detection. The Melbourne Sexual Health Centre (MSHC) changed from clinician-collected to self-collected oropharyngeal swabs for oropharyngeal gonorrhea and chlamydia screening on 16 March 2020 in order to reduce health care worker risk during the COVID-19 pandemic. We compared the proportions of valid and positive samples for gonorrhea and chlamydia among men who have sex with men (MSM) in two time periods; the clinician collection period, between 20 January and 15 March 2020, and the self-collection period, between 16 March and 8 May 2020. A total of 4,097 oropharyngeal swabs were included. The proportion of oropharyngeal swabs with equivocal or invalid results for Neisseria gonorrhoeae was higher in the self-collection period (1.6% [24/1,497]) than in the clinician collection period (0.9% [23/2,600]) (P = 0.038), but the proportions did not differ for the detection of Chlamydia trachomatis The positivity rates of oropharyngeal N. gonorrhoeae (adjusted prevalence ratio [PR], 1.07 [95% confidence interval {CI}, 0.85 to 1.34]) (P = 0.583) and oropharyngeal C. trachomatis (adjusted PR, 0.84 [95% CI, 0.51 to 1.39]) (P = 0.504) specimens did not differ between the two periods. Self-collected oropharyngeal swabs for the detection of N. gonorrhoeae and C. trachomatis have acceptable performance characteristics and, importantly, reduce health care worker exposure to respiratory infections.
