The objective of this article is to describe the epidemiology of lymphogranuloma venereum (LGV) and non-LGV Chlamydia trachomatis anorectal infections in France and to examine the characteristics of the affected populations via a voluntary sentinel surveillance system for LGV between 2010 and 2015. Anorectal samples positive for C. trachomatis (CT) were sent by the participating laboratories to the National Reference Center for CT for LGV identification. Biological and clinical data were collected by biologists and clinicians. There were 1740 LGV episodes and 2248 non-LGV episodes. Continuous monitoring highlighted a sharp increase in the number of LGV and non-LGV anorectal infections, which were 2.3-fold and 6.5-fold, respectively. Most of the infections occurred in men who have sex with men. LGV patients were older than non-LGV patients and were more frequently human immunodeficiency virus (HIV)-positive compared to non-LGV patients. Anorectal LGV was significantly associated with residence in Paris, HIV co-infection, concurrent syphilis and bloody anal discharge. Undocumented patient characteristics were strongly associated with anorectal LGV. The anorectal LGV epidemic is poorly controlled in France. Early detection and prompt treatment of patients and their sexual partners are required to prevent transmission in the context of pre-exposure prophylaxis (PrEP) for HIV infection.

An epidemic of lymphogranuloma venereum among men who have sex with men (MSM) has persisted in Australia for over a decade and virtually all diagnoses are made from rectal samples. We discuss two cases of human immunodeficiency virus-negative MSM who presented with a penile ulcer. The diagnosis can be made by ensuring a swab of any such ulcer is tested for Chlamydia trachomatis.

ObjectivesWe evaluated the prevalence of lymphogranuloma venereum (LGV) in anorectal Chlamydia trachomatis-positive French men who have sex with men (MSM) using pre-exposure prophylaxis (PrEP) for HIV. Here, we describe the clinical, biological and behavioural characteristics of these patients.MethodsLaboratories throughout French metropolitan areas performing routine testing for C. trachomatis sent positive anorectal specimens to the National Reference Centre for bacterial STIs for LGV real-time PCR targeting the pmpH gene. Identification of the C. trachomatis genovar was performed by ompA gene sequencing. For each patient, clinical, biological and sexual behaviour data were collected after obtaining written informed consent.ResultsIn 2017, 486 anorectal C. trachomatis-positive specimens from MSM PrEP users were analysed. A strain of genovar L was detected in 91 cases (18.7%). Patients with LGV were significantly more symptomatic, had more sexual partners and more concurrent syphilis compared with their non-LGV counterparts. OmpA gene sequencing, successful in two-thirds of anorectal C. trachomatis-positive specimens, showed that the LGV cases were mainly of variant L2b (n=33), followed by genovar L2 (n=27) and genetic L2b ompA variants (n=16). In 11 cases, the results indicated the occurrence of genetic exchange between L and non-L genovars.ConclusionsLGV was diagnosed in 18.7% of anorectal C. trachomatis-positive specimens from French MSM using PrEP. LGV testing should be carried out for MSM diagnosed with chlamydia and with a large number of sexual partners, high-risk practices and anorectal symptoms. These patients should be presumptively treated as having LGV. This is the first surveillance study of LGV among MSM PrEP users and monitoring should continue.

Background: Pre-exposure prophylaxis (PrEP) is suitable for high human immunodeficiency virus (HIV)-infection risk people, foremost among whom are males who have sex with other males (MSM). This study evaluated knowledge, attitudes and practices regarding PrEP in a sample of Italian MSM, in order to hypothesize strategies to implement PrEP awareness and use. No previous study has assessed this issue; Methods: An online survey was given to an opportunistic sample of Italian MSM. The questionnaire investigated sexual behaviour and habits, HIV/acquired immune deficiency syndrome (AIDS) knowledge and PrEP awareness, attitudes and practices. Univariable and multivariable logistic regressions were conducted to identify factors associated with PrEP knowledge; Results: A total of 196 MSM participated in this survey. Overall data showed that 87.2% of participants knew what PrEP is, but only 7.5% have ever used it. The main reason for not using PrEP was the cost of the therapy (26.9%). The principal source of PrEP information was the Internet (68.4%). Being regularly tested for HIV was significantly associated with PrEP knowledge (adjusted odds ratio (AdjOR) = 3.16; confidence interval (CI) = 1.06–9.29); Conclusions: Knowledge regarding PrEP was well established, but PrEP use was not equally widespread. It is necessary to improve research on PrEP usage in order to PrEP access to be granted.

Abstract Background Pre-exposure prophylaxis (PrEP) is suitable for human immunodeficiency virus (HIV)high-infection-risk people, foremost amongst males who have sex with other males (MSM). This study evaluated knowledge, attitudes and practices regarding PrEP in a sample of Italian MSM, in order to hypothesize strategies to implement PrEP awareness and use. Methods An online survey was given to an opportunistic sample of Italian MSM. The questionnaire investigated sexual behaviour, knowledge on HIV and PrEP awareness, attitudes and practices. Univariable and multivariable logistic regressions were conducted to identify possible associations with PrEP knowledge. Results A total of 196 MSM completed the survey. Overall data showed very good HIV and safe sexual behaviour knowledge (94.4% of correct answers). Nevertheless, our sample rarely used PrEP because of existing barriers: high therapy price (26.9%)and fear of side effects (23.8%). Only 10.3% of partecipants were informed on HIV and PReP by institutional channels, even less (7.5%) from specialized physicians and general practitioners. The most significant association with PrEP knowledge was having regular HIV-tests (adjusted odds ratio (AdjOR) = 3.16; confidence interval (CI) = 1.06-9.29); Conclusions PreP's Knowledge was well established, but PrEP use was not widespread. It is necessary to improve communication on PrEP and to lower existing barriers in order to grant access to PrEP access. Key messages Barriers to access PrEP have to be lowered. Healthcare personnel has to be involved in PrEP's benefits communication.

Abstract Background Oral daily tenofovir (TFV) disoproxil fumarate/emtricitabine (TDF/FTC) for human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) is highly effective for HIVprevention, yet long-term effects are not fully understood. We investigated the effects of PrEP on the rectal microbiome in a cohort of men who have sex with men (MSM). Methods This cross-sectional analysis included HIV-negative MSM either on PrEP (n = 37) or not (n = 37) selected from an ongoing cohort using propensity score matching. Rectal swabs were used to examine microbiome composition using 16S ribosomal ribonucleic acid gene sequencing, and associations between PrEP use and microbiota abundance were examined. Hair specimens were used to quantify TFV and FTC exposure over the past 6 weeks on a subset of participants (n = 15). Results Pre-exposure prophylaxis use was associated with a significant increase in Streptococcus abundance (adjusted P = .015). Similar associations were identified using least absolute shrinkage and selection operator (LASSO) regression, confirming the increase in Streptococcus and also showing increased Mitsuokella, Fusobacterium, and decreased Escherichia/Shigella. Increased Fusobacterium was significantly associated with increasing TFV exposure. Conclusions Oral TDF/FTC for PrEP is associated with rectal microbiome changes compared to well matched controls, specifically increased Streptococcus and Fusobacterium abundance. This study highlights the need for future investigations of the role of microbiome changes on HIV susceptibility and effectiveness of PrEP.

Abstract Background Human immunodeficiency virus pre-exposure prophylaxis (PrEP) clinical guidelines recommend men who have sex with men (MSM) PrEP users be screened biannually for syphilis and gonorrhea/chlamydia at all anatomic sites. We sought to determine the proportion screened and positive by STI and anatomic site at PrEP initiation and PrEP-care visits and patient-level characteristics associated with screening among MSM PrEP users in Baltimore City, Maryland. Methods Medical records among MSM initiating PrEP between 30 September 2015 and 31 March 2018 were abstracted. STI screening (syphilis and gonorrhea/chlamydia at all anatomic sites) and positivity at PrEP visits ≤12 months following initiation were calculated. Poisson regression with cluster robust SEs was used to assess associations with STI screening. Results Among 290 MSM initiating PrEP, 43.1% (n = 125) were screened per guidelines at PrEP initiation; 79.3% (230), 69.3% (201), 55.9% (162), and 69.3% (201) were screened for syphilis, urogenital, rectal, and oropharyngeal gonorrhea/chlamydia, respectively. Positivity among those screened was syphilis, 7.8% (n = 18/230); gonorrhea, 5.0% urogenital (10/201), 11.1% rectal (18/162), and 7.5% oropharyngeal (15/201); chlamydia, 5.0% urogenital (10/201), 11.7% rectal (19/162), and 1.5% oropharyngeal (3/201). Reported anal and oral sex (vs neither) was independently associated with STI screening (aPR, 2.11; 1.05–4.27) at PrEP initiation. At biannual PrEP-care visits, STI screening was lower and syphilis and rectal gonorrhea/chlamydia positivity was higher. Conclusions Observed STI screening levels and disease burden suggest the effectiveness of STI screening in PrEP care for STI prevention may be limited. Our results suggest providers may be offering screening based on sexual practices; clarification of STI screening guidelines for PrEP users is needed.
