RESUMO

A case of a male with human immunodeficiency virus with plasma genotyping detecting no resistance and a CRF02_AG subtype had a controlled HIV RNA on antiretroviral therapy since 2010. We introduced intramuscular therapy with cabotegravir and rilpivirine. One month later, his HIV RNA was 1500 copies/mL; genotyping found a subtype B with many mutations.

RESUMO

HIV post- exposure prophylaxis (PEP) is a prevention tool for individuals with a recent potential exposure to HIV. Doravirine has been available since 2019 in combination with tenofovir disoproxil fumarate and lamivudine and has not been evaluated as a PEP. DOR/3TC/TDF is our department's most commonly prescribed PEP treatment since 2021. This study evaluates the completion rate of the DOR/3TC/TDF as compared to EVG/c/FTC/TAF for PEP, which was the regimen prescribed until 2020 in our hospital.This retrospective observational study was conducted between January 2020 and September 2021. The subjects included consecutively were adults who consulted for an HIV sexual exposure accident and for whom DOR/3TC/TDF in 2021 or EVG/c/FTC/TAF in 2020 was prescribed. The outcomes were the completion rate to the end of treatment (28 days), the seroconversion rate, and the description of side effects.During the study period, 311 people were included: 140 treated with DOR/3TC/TDF and 171 treated with EVGc/FTC/TAF. Considering subjects with a follow-up visit, the completion rate was 96.8% (90/93) in the DOR/3TC/TDF group, and 94.6% (123/130) in the EVG/c/FTC/TAF group (p-value: 0.53). The number of people lost to follow-up was nearly equivalent in both groups: 27.1% (38/140) in the DOR/3TC/TDF group and 23.4% (40/171) in the EVG/c/FTC/TAF group (p-value: 0.45). A side effect was described for 38% (36/94) in the DOR/3TC/TDF group, and 29.7% (38/128) in the EVG/c/FTC/TAF group. No cases of seroconversion were observed.DOR/3TC/TDF appears to have a similar safety profile to EVG/c/FTC/TAF. Due to its lower cost, it seems to be a treatment option for consideration in the context of HIV-exposure accidents.

RESUMO

OBJECTIVES: Asymptomatic sexually transmitted infections (STI) are frequent among men who have sex with men (MSM). Identifying asymptomatic STIs is a crucial issue, not only for secondary but also for primary prevention, as early treatment can reduce transmission risk. We aimed to develop a self-reported predictive score for early identification of asymptomatic STIs. METHODS: Participants provided clinical data and completed a self-administered questionnaire including sociodemographic variables and behaviors during the 6 previous months. We used multivariable logistic regression to identify factors associated with asymptomatic STIs. We calculated the accuracy of the model by the non-parametric area (AUC) under the receiver-operating-characteristic (ROC) curve to find the optimal discriminant threshold for screening. RESULTS: A total of 781 HIV-positive MSM were included with a mean age of 46.8 years. Asymptomatic STI prevalence was 13.2%. Detectable plasma HIV RNA (adjusted odds ratio (aOR [95% CI): 2.54 [1.23;5.25]), inconsistent condom use during anal sex (2.20 [1.36;3.56]), group sex (2.00 [1.15;3.45]), during or-genital practices (1.83 [1.12;3.01]), not being in stable relationship (1.70 [1.01;2.66] and an item from a sensation-seeking behavioral scale "I don't like watching porn videos" (1.61 [1.01;2.59] were associated with asymptomatic STI. AUC was 0.7 and with optimal threshold of 0.1082 for this model; sensitivity was 80.4%. Self-reported asymptomatic STI predictive score was built with this threshold according to the 6 factors in the final model. CONCLUSIONS: As this predictive score is not designed to be diagnostic, but to provide indications for diagnostic tests, its ease of administration and sensitivity remain the most important features. Its use in clinical practice for early detection of asymptomatic STIs potentially can reinforce STI primary and secondary prevention.

RESUMO

OBJECTIVES: To assess humoral responses to SARS-CoV-2 Delta-variant in people with HIV (PWH) after BNT162b2-vaccination. DESIGN: Multicenter cohort study of PWH with CD4 + cell count less than 500 cells/µl and viral load less than 50 copies/ml on stable antiretroviral therapy for at least 3 months. METHODS: Anti-SARS-CoV-2 receptor-binding-domain IgG antibodies (anti-RBD IgG) were quantified and neutralization capacity was evaluated by ELISA/GenScript and virus-neutralization-test against the D614G-strain, beta and delta variants before vaccination (day 0) and 1 month after complete schedule (M1). RESULTS: We enrolled 97 PWH, 85 received two vaccine shots. The seroconversion rate for anti-RBD IgG was 97% [95% confidence interval (CI) 90-100%] at M1. Median (IQR) anti-RBD IgG titer was 0.97 (0.97-5.3) BAU/ml at D0 and 1219 (602-1929) at M1. Neutralization capacity improved between D0 (15%; 50% CI 8-23%) and M1 (94%; 95% CI 87-98%) ( P  < 0.0001). At M1, NAbs against the D614G strain, beta and delta variants were present in 82, 77, and 84% PWH, respectively. The seroconversion rate and median anti-RBD-IgG level were 91% and 852 BAU/ml, respectively, in PWH with CD4 + cell count less than 250 ( n  = 13) and 98% and 1270 BAU/ml for CD4 + greater than 250 ( n  = 64) ( P  = 0.3994). NAbs were present in 73% of PWH with CD4 + less than 250 and 97% of those with CD4 + cell count greater than 250 ( P  = 0.0130). NAbs against beta variant were elicited in 50% in PWH with CD4 + cell count less than 250 and in 81% of those with CD4 + cell count greater than 250 ( P  = 0.0292). CD4 + and CD8 + T-cell counts were unchanged, whereas CD19 + B-cell counts decreased after vaccination(208 ±â€Š124 at D0 vs. 188 ±â€Š112 at M1, P  < 0.01). No notable adverse effects or COVID-19 cases were reported. CONCLUSION: Seroconversion rates were high, with delta-neutralization rates similar to those for the D61G strain, after a two-dose BNT162b2 vaccination in PWH.

RESUMO

BACKGROUND: Extended-spectrum ß-lactamase-producing Enterobacterales (ESBL-E) represent a major threat to public health. Little is known on their potential for sexual transmission. METHODS: We recruited individuals at a sexually transmitted infection and human immunodeficiency virus (HIV) outpatient clinic in Paris, France, in whom we evaluated the prevalence of ESBL-E intestinal carriage and, among those testing positive, the proportion with clearance 6 months thereafter. We compared carriage prevalence between groups using logistic regression adjusted for age, geographic origin, travel outside Europe, and antibiotic use in the past 6 months. RESULTS: A total of 2157 individuals participated, of whom 226 (10.5%) were ESBL-E carriers. The proportions of ESBL-E carriers varied across sexual groups and were as follows: HIV-negative men who have sex with men (MSM) and who were on preexposure prophylaxis (PrEP), 16.3% (41 of 251); HIV-negative MSM not on PrEP, 9.7% (47 of 487); HIV-positive MSM, 12.2% (61 of 500); HIV-negative men who have sex exclusively with women, 10.0% (44 of 439); and HIV-negative women who have sex with men, 6.9% (n = 33 of 480). After adjustment, ESBL-E prevalence was significantly higher in HIV-negative MSM on PrEP (P < .001) and HIV-positive MSM (P = .01) than in women who have sex with men. A higher number of sexual partners in the past 6 months was associated with ESBL-E carriage after adjustment (P = .004). Escherichia coli sequence type 14 and blaSHV-12-producing ESBL-E were observed only in MSM. Of 102 individuals with ESBL-E returning for testing, 26 (25%) had carriage at 6 months. CONCLUSION: ESBL-E carriage is more frequent in MSM undergoing PrEP or living with HIV and with increasing number of sexual partners. More research is warranted to understand the consequences of ESBL-E carriage in these populations and how transmission can be reduced.

RESUMO

Objectives: The aim of this study was to estimate the prevalence of anti-microbial resistance (AMR) carriage and its risk factors in hospitalized migrants. Additionally, the prevalence of infectious diseases was evaluated, as well as symptoms of psychological trauma. Methods: We conducted a retrospective monocentric cross-sectional study including all migrant patients recently arrived and hospitalised over a one-year period. Results: Among 101 patients, seventy-nine percent originated from Sub-Saharan Africa. The overall AMR carriage rate was 20.7% [95% CI: 12.4; 28.9%]. We isolated 5/92 methicillin-resistant Staphylococcus aureus strains (5.4%) and 15/92 extended-spectrum beta-lactamase-producing Enterobacteriaceae (16.4%). AMR carriage was associated with older age, region of origin and length of migration. Rates of HIV, HBV, and HCV infection were 39.6%, 32.7%, and 5%, reflecting sampling bias linked to reasons for hospitalization. Eleven percent had serological evidence of treponemasis and 7.8% had Chlamydia trachomatis infection. Symptoms of depression or post-traumatic stress disorder were observed for more than half the patients. Conclusion: It appears essential to offer a systematic and comprehensive post-arrival screening of AMR carriage, infectious diseases and psychological trauma to subjects who experienced migration.

RESUMO

We compared the proportion of participants achieving first undetectable HIV-1 RNA (VL) in seminal plasma (SP) and blood plasma (BP) in 19 men starting dolutegravir-based regimen at primary HIV infection. At baseline, median VL was 6.5 (interquartile range [IQR], 5.6-7.9) and 4.5 (IQR, 3.5-5.0) log10 copies/mL in BP and SP, respectively. Between baseline and week 48, significantly higher proportion of participants achieved first VL below limit of quantification in SP (93.0%) than in BP (84.2%; P = .008). Time to first undetectable VL was 8 weeks in SP (95% confidence interval [CI], 5.6-10.4) and 24 weeks in BP (95% CI, 14.1-33.9).

RESUMO

OBJECTIVES: Pre-exposure chemoprophylaxis “PrEP”, a new prevention tool against HIV for high-risk populations, has been available in France since 2016 in France. The first prescription should occur in CeGIDD or hospital and, its renewal and follow-up can be made by the GP. The analysis of barriers to prescribing PrEP and its follow-up by GP is essential to guide public health actions in order to reach the objectives necessary to observe an inflection of new HIV contaminations. METHODS: In this descriptive study, on general practitioners who were surveyed about their opinions and current practices of PrEP on the French territory from August to October 2018. RESULTS: 351 responded to the survey, with an estimated response rate of 11%. Most clinicians (88.9%) supported PrEP but only 6.3% had provided it and 12.8% of them did PrEP monitoring. The non-providers self-assessed for 97% of them, as their knowledge of PrEP was low or very low. The significant barriers to providing PrEP among non-adopters were the lack of training received (90.6% vs 59,1% for adopters, P < 0.001), the assessment of patient as “not at risk for HIV” (29.8% vs 0%, P = 0.003), not having a private health assurance (34.7% vs 13.6%, P = 0.04), the lack of knowledge about patient sexuality (27.1% vs 4.5%, P = 0.02). The absence of a first prescription was a barrier only for PrEP follow-up and was over-represented in this group (33.3% vs 18.3% for non-adopters, P = 0.02). CONCLUSION: This study shows that GPs are interested in providing PrEP despite their barriers. The management of PrEP in general practice must be improved, particularly through the training of general practitioners in the context of continuing medical education and by an institutional evolution in the extension of provide PrEP to increase the interest in global health management to overcome these barriers.

RESUMO

The burden of STIs is particularly high in HIV-infected MSM patients. A recent increase in STIs prevalence has been noticed in the US and western European countries. We aim to assess trends in asymptomatic STIs following the publication of recommendations for STIs screening, i.e. Chlamydia (CT) and gonorrhea (NG). Seventeen centers located in the Paris area participated in the study. All asymptomatic HIV-infected MSM patients attending a follow up consultation were proposed to participated in the study. Asymptomatic patients were included over 2 periods: period 1 from April to December 2015 and period 2 from September to December 2017. Etiologic diagnosis of STIs including hepatitis B, C, syphilis, was performed using a serological test, including a non-treponemal titer with a confirmatory treponemal assay for syphilis. CT and NG were screened using a nucleic acid amplification test (NAATs) on 3 anatomical sites, i.e. urine, rectal and pharyngeal. Overall, 781 patients were included: 490 and 291 in periods 1 and 2 respectively. Asymptomatic CT, NG, and syphilis were diagnosed in 7.5%, 4.8% and, 4.2% respectively. The rate of patients having a multisite asymptomatic infection was 10.2% and 21.1% for CT and NG respectively. The most frequently involved anatomical sites for CT and NG asymptomatic infections were anorectal (66.1% and 55.2% respectively) and pharyngeal (47.4% and 60.5% respectively). CT and NG asymptomatic infection increased by 1.3- and 2-fold respectively between the two periods while syphilis decreased by 3 folds. Our results encourage to reconsider multisite screening for CT and NG in asymptomatic HIV positive MSM as the yield of screening urinary samples only might be low. Despite the more systematic STI screening of asymptomatic HIV positive MSM the prevalence of STI is increasing in MSM in France. Therefore, this strategy has not led to alter CT and NG transmission. The decrease of syphilis might involve self-medication by doxycycline, and the intensification of syphilis screening.

RESUMO

OBJECTIVES: 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). METHODS: 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. RESULTS: 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. CONCLUSION: 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.

RESUMO

PURPOSE: To compare peripapillary retinal nerve-fiber-layer (pRNFL) thickness, total retina macular volume, and ganglion-cell-layer (GCL) macular volume and thickness between persons living with HIV (PLHIVs) with well-controlled infections and good immune recovery, and sex- and age-matched HIV-uninfected controls (HUCs). METHODS: This prospective cross-sectional study (www.clinicaltrials.gov identifier: NCT02003989) included 56 PLHIVs, infected for ≥10 [median 20.2] years and with sustained plasma HIV-load suppression on combined antiretroviral therapy (cART) for ≥5 years, and 56 matched HUCs. Participants underwent spectral-domain optical coherence tomography (SD-OCT) with thorough ophthalmological examinations and brain magnetic resonance imaging (MRI). Their overall and quadrant pRNFL thicknesses, total macular volumes, and GCL macular volumes and thicknesses were compared. Cerebral small-vessel diseases (CSVD) complied with STRIVE criteria. RESULTS: Median [interquartile range, IQR] ages of PLHIVs and HUCs, respectively, were 52 [46-60] and 52 [44-60] years. Median [IQR] PLHIVs' nadir CD4+ T-cell count and current CD4/CD8 T-cell ratio were 249/µL [158-350] and 0.95 [0.67-1.10], respectively; HIV-seropositivity duration was 20.2 [15.9-24.5] years; cART duration was 16.8 [12.6-18.6] years; and aviremia duration was 11.4 [7.8-13.6] years. No significant between-group pRNFL thickness, total macular volume, macular GCL-volume and -thickness differences were found. MRI-detected CSVD in 21 (38%) PLHIVs and 14 (25%) HUCs was associated with overall thinner pRNFLs, and smaller total retina and GCL macular volumes, independently of HIV status. CONCLUSIONS: SD-OCT could not detect pRNFL thinning or macular GCL-volume reduction in well-sustained, aviremic, cART-treated PLHIVs who achieved good immune recovery. However, CSVD was associated with thinner pRNFLs and GCLs, independently of HIV status.

RESUMO

We evaluated an elvitegravir-cobicistat-emtricitabine-tenofovir alafenamide single-tablet regimen for human immunodeficiency virus postexposure prophylaxis. The completion rate and adherence were good, and the tolerance was acceptable; no seroconversion was observed. We confirm that this regimen could be appropriate for postexposure prophylaxis.

RESUMO

INTRODUCTION: Mixed hepatitis C virus (HCV) genotype (GT) infections are clinically important as different genotypes have varied sensitivities to direct-acting antivirals (DAAs). A high prevalence of mixed GT infections was observed in individuals who inject drugs and had multiple HCV exposures. The prevalence of mixed HCV GT infections in men who have sex with men (MSM) and high-risk behaviors was investigated by ultra-deep sequencing (UDS). METHODS: NS5B fragment was sequenced from viruses of patients with recent HCV infection: there were 50 HIV-positive and 18 HIV-negative patients, including 13 from the ANRS Pre-Exposure Prophylaxis (PrEP) IPERGAY study. UDS data were analysed using Geneious (version 10.3.2). Phylogenetic trees were constructed using FastTree (version 2.1). RESULTS: HCV sequencing showed GT1a (47.1%), GT4d (41.2%), GT3a (8.8%) and GT2k (2.9%). We detected three (4.4%) mixed GT infections: one between predominant GT4d and minority GT1a, one between predominant GT4d and minority GT1b, and one between predominant GT1a and minority GT4d virus. The rates of minority GT viral populations detected in viruses of the three patients with mixed GT infections were 0.32%, 10.7%, and 1.3%, respectively. The first two patients were HIV co-infected and the third was HIV-negative under PrEP. The anti-HCV treatment was successful in all three patients. CONCLUSION: This work showed uncommon mixed HCV GT infections in MSM at high risk of multiple HCV exposures. The impact of these infections on treatment response has not been established but further studies on more patients are necessary. To prevent treatment failure in this population, regular monitoring of treatment response is needed, particularly when pan-genotypic treatment is not used.
