•Analysis of pre-treatment resistance-associated substitutions (RASs) among recently HCV-infected MSM with risky behaviours.•Uncommon NS3/NS5A RASs among recently HCV-infected MSM with risky ...behaviour.•High prevalence of subtype-specific polymorphisms in GT4d infections.•Reassurance of the clinical management of HCV infection in this population.
Presence of baseline hepatitis C virus (HCV) resistance-associated substitutions (RASs) can impair treatment outcome of direct-acting antivirals. We investigated the prevalence of pre-treatment HCV resistance among recently HCV-infected men who have sex with men (MSM) with high risk behaviours, either human immunodeficiency virus (HIV) co-infected or at high risk of HIV acquisition and under pre-exposure prophylaxis (PrEP).
NS5A and NS3 fragments were deep sequenced on pre-treatment samples of 72 subjects using Illumina MiSeq paired-end sequencing technology. Ultra-deep sequencing data were analysed by SmartGene® platform. RASs mentioned in the literature were analysed and interpreted depending on genotype (GT) at 10% cut-off.
HCV genotyping showed 36 (50.0%) GT1a, 31 (43.1%) GT4d and 5 (6.9%) GT3a infections. Fifty-five patients (76.4%) were co-infected with HIV and 15 (20.8%) received PrEP. In GT1a viruses, NS3 RASs were found in 4/30 viruses (13.3%; S122 G/N, R155 K and I170 V) and Q80 K polymorphism was present in 14/30 viruses (46.7%). No NS3 RASs were detected in GT4d and GT3a viruses. NS5A RASs were detected in 3/36 GT1a viruses (8.3%; Q30E/R, L31 M and H58 L). NS5A subtype-specific polymorphisms L30R and T58 P were found at high frequencies in 31/31 (100%) and 16/31 (51.6%) GT4d viruses, respectively. One RAS M31 L was also observed along with the polymorphisms L30R and T58 P. No NS5A RASs were detected in GT3a viruses.
A low level of RASs to NS3 and NS5A inhibitors in pre-treatment samples was detected in the study population. Our findings reassure the clinical management of HCV infection in this high-risk population.
Monkeypox virus (MPXV) is currently spreading among men who have sex with men, outside of sub-Saharan Africa, and close contact during sex seems to be one of the key pathways of viral transmission in ...the current outbreak. Our aim was to describe the distribution of MPXV in the human body, as it might play a role in its dissemination through sexual contact.
The study population in this case series consisted of patients with confirmed MPXV infection attending the Pitié-Salpêtrière Hospital (Paris, France), who had been sampled from multiple anatomical sites, including skin, anus, throat, blood, urine, and semen, at diagnosis and 2 weeks later. We compared the proportion of positive samples and MPXV viral loads (given as PCR cycle thresholds Ct) between anatomical sites, and between day 0 (D0) and D14.
Overall, 356 samples were collected between May 20 and June 13, 2022, from 50 men with a median age of 34 years (IQR 29–40). 22 (44%) of the 50 men were classified as HIV-negative on day (D)0, and 22 (44%) were living with HIV. At D0, MPXV detection was more frequent from skin (44 88% of 50), anus (30 71% of 42), and throat (36 77% of 47) than from blood (13 29% of 45), urine (nine 22% of 41), or semen (13 54% of 24). Viral loads were significantly higher from skin lesions (Ct 19·8) and anal samples (Ct 20·9) than from throat (Ct 27·2), blood (Ct 32·8), urine (31·1), or semen samples (Ct 27·8). When analysing the 107 samples taken from 24 patients at D14, the proportion of positive samples strongly decreased between D0 and D14 at all sites: skin (four 22% of 18), anus (two 9% of 22), throat (none of 21), blood (one 5% of 21), urine (none of 14), and semen (two 9% of 11).
These data contribute to a better understanding of how the virus might spread between sexual partners over a relatively short period of time. High MPXV viral loads from skin and mucosa, including genital and anal sites, suggest that transmission most likely occurs through direct body contact rather than through the respiratory route or contact with body fluids, which should help to refine the prevention messages delivered to individuals most exposed to the virus.

Chemsex is a growing concern among men who have sex with men (MSM). COVID-19 lockdowns have had consequences on social and sexual interactions. We aimed to assess changes in chemsex practices during ...COVID-19 lockdown in France among MSM and factors associated with maintaining or increasing chemsex practice.
Repeated face-to-face questionnaires were conducted at "Le 190" Sexual Health Center, Paris, France, exploring lifestyle, sexual, and chemsex practices, COVID-19 concerns and mental health before and during second lockdown in France (30/10/2020-15/12/2020). Inclusion criteria were chemsex practices at least 3 times throughout lifetime and at least once in the 3 months before second lockdown. The primary end point was the proportion of participants who declared having stopped, decreased, maintained, or increased their chemsex practice during lockdown. Univariable and multivariable logistic regressions were used to analyze factors associated with evolutions of chemsex practice.
Ninety-three MSM were included: 66% HIV-positive and 30% taking PrEP. Drugs most used were cathinones (91%) and GHB/GBL (52%). Participants reported stopping, decreasing, maintaining, and increasing chemsex drugs use in 14%, 22%, 22%, and 42% of cases, respectively. Despite this overall increase in chemsex practice, MSM decreased their number of sexual partners. Factors significantly associated with maintaining or increasing chemsex drugs use were feeling lonely (OR = 3.24), craving (OR = 4.51), and working during lockdown (OR = 3.27), contrasting with fear of COVID-19 (OR = 0.31).
Restriction measures lead to changes in sexual behavior and seem to increase chemsex practice. Maintaining care for most isolated patients should be a priority in COVID-19 context.
While stigma associated with HIV infection is well recognised, there is limited information on the impact of HIV-related stigma between men who have sex with men and within communities of gay men. ...The consequences of HIV-related stigma can be personal and community-wide, including impacts on mood and emotional well-being, prevention, testing behaviour, and mental and general health. This review of the literature reports a growing division between HIV-positive and HIV-negative gay men, and a fragmentation of gay communities based along lines of perceived or actual HIV status. The literature includes multiple references to HIV stigma and discrimination between gay men, men who have sex with men, and among and between many gay communities. This HIV stigma takes diverse forms and can incorporate aspects of social exclusion, ageism, discrimination based on physical appearance and health status, rejection and violence. By compiling the available information on this understudied form of HIV-related discrimination, we hope to better understand and target research and countermeasures aimed at reducing its impact at multiple levels.

HIV self-tests (HSTs) have been deployed to reduce the burden of undiagnosed HIV infections in subpopulations undertested. We assumed that patients attending sexual health centres could themselves ...distribute HSTs in their close network. This study aimed to assess the proportion and the characteristics of the participants who distributed HSTs, as well as the characteristics of people who received HSTs.
Three HSTs were given to patients attending "Le 190" Sexual Health Center, Paris, France, having consented for the study, between July 2018 and August 2020. Participants had to distribute HSTs within 6 months, preferably to individuals in their close circle who have not been tested for a long time. Then they had to complete a self-questionnaire, exploring HIV status, sexual practices, number of distributed HSTs, profile of persons who received HSTs, and if known, result of used HSTs. Univariable logistic regression was used to determine factors associated with HST distribution.
Overall, 682/1062 (64%) patients accepted to be included in the study, and 283/682 (42%) completed the questionnaire. 97% were men who have sex with men (MSMs), including 86 (30%) HIV-positive individuals and 119 (42%) HIV Pre-Exposure Prophylaxis (PrEP) users. The proportion of participants having distributed 0, 1, 2 or 3 HSTs was 31%, 15%, 27% and 27%, respectively. Participants having distributed at least one HST (n=195, 69%) were more likely to have previously used HSTs themselves (OR=3.90, 95% CI=1.84 to 8.29, p<0.001). On the 901 HSTs in possession of participants who answered the questionnaire, 455 (50%) were distributed. 79% of recipients were MSMs, and 42% of whom had not been tested for more than 1 year. The result was known for 220 HSTs, including 5 positive (2.3%).
MSMs attending sexual health centres could be good disseminators of HSTs, targeting a population with high level of undiagnosed HIV infections, especially if they have already experimented it.
