In January 2016, the French Medicine Agency initiated a Temporary Recommendation for Use (TRU) to allow the use of oral intake of tenofovir disoproxil fumarate and emtricitabine for pre-exposure prophylaxis (PrEP) in adults at high risk of HIV. We report the results of the first year of PrEP implementation in France.


Data were collected by physicians using a secured web subject-monitoring interface, with two forms: an initiation form, with patients’ baseline characteristics, and an HIV seroconversion form. Univariate and adjusted multivariate analysis using a logistic regression model were performed to identify baseline factors associated with on-demand PrEP regimen prescription.


From 4 January 2016 to 28 February 2017, 3405 subjects were enrolled, with 2774 initiation forms completed; 98.1% were male and 96.9% were MSM. An on-demand regimen was prescribed to 57% of subjects. Older age (OR for participants older than 50 years = 1.76, 95% CI 1.35–2.3, P < 0.001) and site of prescription (OR of former IPERGAY sites = 2.28, 95% CI 1.84–2.83, P < 0.001) were associated with on-demand prescription. Those reporting sexually transmitted infection (STI) and condomless anal sex with at least two different partners were less likely to receive on-demand PrEP (OR = 0.68, 95% CI 0.57–0.82 and 0.75, 95% CI 0.57–0.98, respectively; P < 0.05 for all). Four breakthrough HIV infections were reported during the study, in the context of PrEP interruption or acute infection at the time of PrEP initiation.


In a real-life setting in France, PrEP was used, either daily or on-demand, mostly by MSM, with breakthrough infections being rare.

Key Points

  • Question  – Is the use of HIV preexposure prophylaxis (PrEP) associated with increased risk of sexually transmitted infections (STIs) among individuals at high risk of HIV infection?
  • Findings  – In this longitudinal study of 2981 mostly gay and bisexual men who received daily HIV preexposure prophylaxis, STI incidence was 91.9 per 100 person-years, with 736 participants (25%) accounting for 2237 (76%) of all STIs. Among 1378 participants with preenrollment STI testing data available, receipt of PrEP after study enrollment was associated with an increased incidence of STIs compared with preenrollment (adjusted incidence rate ratio, 1.12).
  • Meaning  – Findings suggest the importance of frequent testing for STIs among gay and bisexual men using PrEP.




Emerging evidence suggests that risk of bacterial sexually transmitted infections (STIs) increases among gay and bisexual men following initiation of HIV preexposure prophylaxis (PrEP).


To describe STI incidence and behavioral risk factors among a cohort of predominantly gay and bisexual men who use PrEP, and to explore changes in STI incidence following PrEP commencement.

Design, Setting, and Participants  

The Pre-exposure Prophylaxis Expanded (PrEPX) Study, a multisite, open-label intervention study, was nested within the Australian Collaboration for Coordinated Enhanced Sentinel Surveillance (ACCESS) clinic network. A total of 4275 participants were enrolled (July 26, 2016–April 1, 2018) in Victoria, Australia. Of these, 2981 enrolled at 5 ACCESS clinics (3 primary care, 1 sexual health, and 1 community-based HIV rapid testing service), had at least 1 follow-up visit, and were monitored until April 30, 2018.


Upon enrollment, participants received daily oral tenofovir disoproxil fumurate and emtricitabine for HIV PrEP, quarterly HIV and STI testing, and clinical monitoring.

Main Outcomes and Measures  

The primary outcome was incidence of chlamydia, gonorrhea, or syphilis. Incidence rates and hazard ratios describing behavioral risk factors of STI diagnosis were calculated. Incidence rate ratios (IRRs), adjusted for change in testing frequency, described changes in STI incidence from 1-year preenrollment to study follow-up among participants with preenrollment testing data (n = 1378).


Among the 2981 individuals (median age, 34 years [interquartile range, 28-42]), 98.5% identified as gay or bisexual males, 29% used PrEP prior to enrollment, 89 (3%) withdrew and were censored at date of withdrawal, leaving 2892 (97.0%) enrolled at final follow-up. During a mean follow-up of 1.1 years (3185.0 person-years), 2928 STIs were diagnosed among 1427 (48%) participants (1434 chlamydia, 1242 gonorrhea, 252 syphilis). STI incidence was 91.9 per 100 person-years, with 736 participants (25%) accounting for 2237 (76%) of all STIs. Among 2058 participants with complete data for multivariable analysis, younger age, greater partner number, and group sex were associated with greater STI risk, but condom use was not. Among 1378 participants with preenrollment testing data, STI incidence increased from 69.5 per 100 person-years prior to enrollment to 98.4 per 100 person-years during follow-up (IRR, 1.41 [95% CI, 1.29-1.56]). After adjusting for testing frequency, the increase in incidence from 1 year preenrollment to follow-up was significant for any STI (adjusted IRR, 1.12 [95% CI, 1.02-1.23]) and for chlamydia (adjusted IRR, 1.17 [95% CI, 1.04-1.33]).

Conclusions and Relevance  

Among gay and bisexual men using PrEP, STIs were highly concentrated among a subset, and receipt of PrEP after study enrollment was associated with an increased incidence of STIs compared with preenrollment. These findings highlight the importance of frequent STI testing among gay and bisexual men using PrEP.

An effective post-exposure prophylaxis (PEP) strategy may limit the spread of infection. However, there is no consensus regarding PEP for Middle East respiratory syndrome coronavirus (MERS-CoV) infection. We assessed the efficacy of ribavirin and lopinavir/ritonavir as PEP for healthcare workers (HCWs) exposed to patients with severe MERS-CoV pre-isolation pneumonia. We assessed the safety of PEP regimen. We retrospectively enrolled HCWs with high-risk exposure to MERS-CoV pre-isolation pneumonia. HCWs who received PEP therapy were classified into the PEP group. PEP therapy was associated with a 40% decrease in the risk of infection. There were no severe adverse events during PEP therapy.

In the UK, HIV incidence among men who have sex with men (MSM) has remained high for several years, despite widespread use of antiretroviral therapy and high rates of virological suppression. Pre-exposure prophylaxis (PrEP) has been shown to be highly effective in preventing further infections in MSM, but its cost-effectiveness is uncertain.


In this modelling study and economic evaluation, we calibrated a dynamic, individual-based stochastic model, the HIV Synthesis Model, to multiple data sources (surveillance data provided by Public Health England and data from a large, nationally representative survey, Natsal-3) on HIV among MSM in the UK. We did a probabilistic sensitivity analysis (sampling 22 key parameters) along with a range of univariate sensitivity analyses to evaluate the introduction of a PrEP programme with sexual event-based use of emtricitabine and tenofovir for MSM who had condomless anal sexual intercourse in the previous 3 months, a negative HIV test at baseline, and a negative HIV test in the preceding year. The main model outcomes were the number of HIV infections, quality-adjusted life-years (QALYs), and costs.


Introduction of such a PrEP programme, with around 4000 MSM initiated on PrEP by the end of the first year and almost 40 000 by the end of the 15th year, would result in a total cost saving (£1·0 billion discounted), avert 25% of HIV infections (42% of which would be directly because of PrEP), and lead to a gain of 40 000 discounted QALYs over an 80-year time horizon. This result was particularly sensitive to the time horizon chosen, the cost of antiretroviral drugs (for treatment and PrEP), and the underlying trend in condomless sex.


This analysis suggests that the introduction of a PrEP programme for MSM in the UK is cost-effective and possibly cost-saving in the long term. A reduction in the cost of antiretroviral drugs (including the drugs used for PrEP) would substantially shorten the time for cost savings to be realised.

Tenofovir disoproxil fumarate (TDF) has been used worldwide in antiretroviral regimens of HIV infected patients since being approved by the U.S. Food and Drug Administration in 2001. TDF can cause renal tubular dysfunction and reduced renal function [1]. In its fully developed form, TDF renal dysfunction is associated with hypophosphatemia, renal phosphate wasting and other features of Fanconi syndrome [1]. Cases of TDF-associated Fanconi syndrome have been reported predominantly among patients with HIV infection [1]. There has been no excess risk of renal tubular toxicity with TDF-emtricitabine (TDF-FTC) detected in large placebo controlled trials of HIV pre-exposure prophylaxis (PrEP) [2, 3]. One other well-documented likely Fanconi syndrome has been reported in an online supplement to the latter paper [3]. Herein, we report an additional case of this previously described phenomenon.

Several studies have demonstrated the efficacy of the oral pre-exposure prophylaxis (PrEP) with tenofovir (with or without emtricitabine) on preventing HIV-negative partners of HIV infected patients to become infected through sexual contacts. PrEP is already available in the United States and now is approved by European Medicine Agency. In this setting we would like to gauge physicians’ knowledge, acquaintance with and attitude to include PrEP in their clinical practice. A cross sectional survey was conducted among Italian physicians expert on antiretroviral therapy. Out of 146 physicians, 35% of participants declared to be familiar with PrEP but only 46% of them believed that, currently, there are not enough reasons to make it available in Italy. 51% of physicians have already been attracted to prescribe it and 63.4% have been openly asked about PrEP. The main concerns noticed were: the risk of acquire other sexual transmitted diseases (STDs) (70% of physicians feared that PrEP could favor STDs spread), the potential harmful of PrEP if not adequately implemented and, especially the risk of possible side effects if not properly used. Nevertheless, 55.9% of participants believed that Health Authorities face an ethical obligation to make PrEP available as part of the strategies to protect from HIV transmission and half of the respondents asked for further researches to better define the role for PrEP. Attitudes regarding PrEP impact on Italian National Health Organization were also very interesting: 57.5% of participants did not believe that investing in PrEP would be an appropriate use of healthcare resources, while 70.6% affirmed that PrEP’s financial coverage should not be funded by the Italian National System of Health (SSN). This survey showed a high awareness of PrEP potential among Italian physicians coupled with a great deal of skepticism about how and if implementing it in clinical practice.

Daily, oral use of tenofovir disoproxil fumarate and emtricitabine (TDF-FTC) for preexposure prophylaxis (PrEP) is an effective strategy to prevent acquisition of HIV infection. It is important to monitor PrEP uptake at the national level to increase our understanding of trends in its utilization, but national HIV surveillance data do not include PrEP uptake. Our objective was to develop feasible methods to estimate PrEP uptake, and to estimate uptake each year among commercially insured persons during 2010-2014.


We conducted a retrospective analysis of the 2010–2014 MarketScan database, a national sample of persons with commercial health insurance in the United States. We developed an algorithm to identify persons aged ≥16 years who were prescribed TDF-FTC for PrEP each year. We generated nationally representative estimates of prevalence of persons prescribed PrEP.


We found a significantly increasing trend in the proportion of persons prescribed TDF-FTC for PrEP over the study period, with 417 users in 2010 and 9,375 users in 2014 (P < 0.001). In 2014, among PrEP users 97% were male and 98% resided in metropolitan areas. Over the time period studied, the numbers of women prescribed PrEP were low.


Our analytic methodology provides the only feasible means to monitor PrEP uptake in the United States. While a marked increasing trend in uptake was observed for males, the number of females who used PrEP remained very low during the study period. Interventions are needed to increase PrEP use by women at substantial risk of acquiring HIV infection.
