RESUMO
INTRODUCTION: Polypharmacy can lead to drug-drug interactions (DDIs), especially with ART. The burden of co-medications, including over-the-counter (OTC) drugs and self-medications, could be underestimated. We aimed to investigate the proportion of people living with HIV (PLHIV) with declared and undeclared co-medications, as well as their potential burden. METHODS: We conducted a national, multicentre, 1 week cross-sectional study between 10 December and 16 December 2019 in 23 French hospitals amongst consecutive adult PLHIV presenting for a routine outpatient visit. A standardized questionnaire filled in by the physicians assessed all medications and other active chemical substances taken by the PLHIV. RESULTS: Overall we enrolled 496 participants from 23 centres. Median age was 50.6 years; ART regimens included an integrase inhibitor in 61% (nâ=â302), an NNRTI in 34% (nâ=â169) and a PI in 14% (nâ=â70) of the cases. Co-medications involved 392 (79%) PLHIV, among which 85 (17%) received polypharmacy (≥5 medications). Previously unknown co-medications or other active substances were found for 32% (nâ=â159) of the participants. Corticosteroids (9%, nâ=â46) and proton pump inhibitors (10%, nâ=â50) were frequently administered. These co-medications did not differ according to age range. Illegal drug use was declared by 11% (nâ=â54) and OTC drugs by 23% (nâ=â113) of PLHIV. Potential DDIs were discovered for 11% (nâ=â53), leading to treatment modifications in 47% (25/53) of cases. CONCLUSIONS: Potential DDIs that lead to therapeutic modifications remain significant whatever the age of PLHIV. More devoted time to identify co-medications and OTC treatment is needed in all PLHIV.

BACKGROUND: In a 4 days/week (4/7 days) maintenance strategy (ANRS-170 QUATUOR trial), the virological impact of an intermittent strategy was assessed by ultrasensitive virological analyses of reservoirs and resistance. METHODS: HIV-1 total DNA, ultra-sensitive plasma viral load (USpVL) and semen VL were measured in the first 121 participants. Sanger and ultra-deep sequencing (UDS) were performed on the HIV-1 genome (Illumina technology) according to the ANRS consensus. A generalized estimation equation with a Poisson distribution was used to compare changes in the proportion of residual viraemia, detectable semen HIV RNA and HIV DNA within and between the two groups over time. RESULTS: The proportion of participants with residual viraemia at Day 0 (D0) and Week 48 (W48) was 16.7% and 25.0% in the 4/7 days group and 22.4% and 29.7% in the 7/7 days group, respectively (+8.3% versus +7.3%, P = 0.971). The proportion of detectable DNA (>40 copies/106 cells) at D0 and W48 was 53.7% and 57.4% in the 4/7 days group and 56.1% and 51.8% in the 7/7 days group, respectively (+3.7% versus -4.3%, P = 0.358). Semen HIV RNA was detectable (≥100 copies/mL) in 2.2% of participants at D0 and 4.5% at W48 in the 4/7 days group versus 6.1% and 9.1% in the 7/7 days group, respectively (+2.3% versus +3.0%, P = 0.743). Emerging resistance at failure was more frequent in the 4/7 days group detected by Sanger sequencing: 3/6 participants versus 1/4 in the 7/7 days group, and similar with the UDS assay: 5/6 versus 4/4, respectively. CONCLUSIONS: These findings support the potency of a 4/7 days maintenance strategy on virological suppression at the reservoirs and emergent resistance level, including minority variants.

COVID-19 is characterized by respiratory symptoms of various severities, ranging from mild upper respiratory signs to acute respiratory failure/acute respiratory distress syndrome associated with a high mortality rate. However, the pathophysiology of the disease is largely unknown. Shotgun metagenomics from nasopharyngeal swabs were used to characterize the genomic, metagenomic and transcriptomic features of patients from the first pandemic wave with various forms of COVID-19, including outpatients, patients hospitalized not requiring intensive care, and patients in the intensive care unit, to identify viral and/or host factors associated with the most severe forms of the disease. Neither the genetic characteristics of SARS-CoV-2, nor the detection of bacteria, viruses, fungi or parasites were associated with the severity of pulmonary disease. Severe pneumonia was associated with overexpression of cytokine transcripts activating the CXCR2 pathway, whereas patients with benign disease presented with a T helper "Th1-Th17" profile. The latter profile was associated with female gender and a lower mortality rate. Our findings indicate that the most severe cases of COVID-19 are characterized by the presence of overactive immune cells resulting in neutrophil pulmonary infiltration which, in turn, could enhance the inflammatory response and prolong tissue damage. These findings make CXCR2 antagonists, in particular IL-8 antagonists, promising candidates for the treatment of patients with severe COVID-19.

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% (nâ =â 33 of 480). After adjustment, ESBL-E prevalence was significantly higher in HIV-negative MSM on PrEP (Pâ <â .001) and HIV-positive MSM (Pâ =â .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 (Pâ =â .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.

OBJECTIVES: To assess the impact on the estimated glomerular filtration rate (eGFR) of different tenofovir disoproxil/emtricitabine dosing regimens for HIV pre-exposure prophylaxis (PrEP). PATIENTS AND METHODS: We included in the study individuals with baseline eGFRâ>â50â mL/min/1.73â m2 who initiated PrEP in the ongoing ANRS-PREVENIR PrEP cohort. We retrospectively classified PrEP users in three groups: 'on-demand' (reported at ≥75% of study visits), 'daily' (≥75% of study visits) or 'switches'. We compared the area under curve (AUC) of the eGFR variation from baseline (ΔeGFR) between groups using analysis of covariance, and assessed factors associated with a negative AUC of ΔeGFR. RESULTS: From May 2017 to October 2020, 1253 PrEP-naïve participants (98% of MSM) were included in the study with a median follow-up of 22 months. 499 (40%), 494 (39%) and 260 (21%) users were in the group daily, on-demand and switches, respectively, for a median number of pills taken per week of 6, 1.7 and 4. The mean AUC of the ΔeGFR was -1.09â mL/min/1.73â m2 in the daily PrEP group, -0.69â mL/min/1.73â m2 in the switches group and +0.18â mL/min/1.73â m2 with on-demand PrEP. In a model adjusted on baseline age and eGFR, the AUC of the ΔeGFR was significantly higher with on-demand PrEP compared to daily PrEP (Pâ=â0.037). Independent factors associated with a negative AUC of ΔeGFR were a daily PrEP regimen, a switches regimen, an ageâ>â40 years and a baseline eGFR≥90â mL/min/1.73â m². CONCLUSIONS: On-demand PrEP dosing had a smaller impact on eGFR evolution than daily PrEP, but the difference was not clinically relevant.

BACKGROUND: The Bacillus Calmette-Guerin (BCG) is a life-attenuated form of Mycobacterium bovis widely used as immunotherapy for localized bladder cancer. Adverse reactions to intravesical BCG instillations are rare. CASE: We describe a 70-year-old man with a history of an aortobifemoral bypass graft, placement of a synthetic mesh for treatment of a ventral hernia and, most recently, superficial bladder cancer treated with BCG therapy. Ten months after his final intravesical BCG instillation, he complained of fever and asthenia. After 12 months of investigation, he was diagnosed with Mycobacterium bovis infection of his aortobifemoral bypass graft and abdominal mesh, with Streptococcus intermedius superinfection. The bypass graft was excised and replaced with an in situ arterial allograft, the abdominal mesh was removed, and treatment started with amoxicillin, isoniazid, rifampicin and ethambutol. Several additional vascular interventions were needed for allograft degradation, but 12 months after the final procedure, outcome was good. DISCUSSION AND CONCLUSIONS: Among 35 cases of mycotic aneurysm reported after BCG therapy in the last 10 years, only one involved a vascular prosthesis. Surgical repair of such aneurysms using prosthetic grafts is commonly performed, associated with anti-mycobacterial treatment. Prognosis is poor with mortality of 14% (4/35) and a 26% rate of aneurysm recurrence under treatment (9/35).

BACKGROUND: Kaposi sarcoma (KS)-associated herpesvirus (KSHV) subtype depends mostly on patient origin. The current study aimed to assess KSHV diversity in a population of men who have sex with men (MSM) living in France. METHODS: The study included 264 patients. In 65 MSM, including 57 human immunodeficiency virus (HIV)-infected men with KS, multicentric Castleman disease, or primary effusion lymphoma and 8 HIV-uninfected men receiving HIV preexposure prophylaxis (PrEP), we performed KSHV typing with K1 open reading frame Sanger and KSHV whole-genome sequencing. In 199 other patients, we performed real-time polymerase chain reaction screening for the new variant. RESULTS: We found that 51% of KSHV-strains were subtype C (85% C3), and 33% were subtype A. Four patients with severe KSHV disease (2 with visceral KS, 1 with multicentric Castleman disease, and 1 with primary effusion lymphoma) and 1 asymptomatic PrEP user had a new variant resembling the Ugandan subtype F, but with different K1 open reading frame and KSHV whole-genome sequences and a different epidemiological context (MSM vs African population). Its prevalence was 4.5% in Caucasian MSM, and it was absent in other epidemiological groups. CONCLUSIONS: Subtype C predominated among MSM living in France. The new F variant was identified in Caucasian MSM and associated with severe KSHV disease, suggesting that subtype F could be split into F1 and F2 variants. Careful screening for this variant may be required in MSM, given the severe clinical presentation of associated diseases.

OBJECTIVES: Biofilm production in extended spectrum ß-lactamase (ESBL)-producing Enterobacteriaceae provides a favourable environment for the exchange of antibiotic-resistance genes and could facilitate widespread dissemination. We aimed to assess biofilm development in ESBL-producing E. coli and K. pneumoniae isolates and determine how development relates to microbiological characteristics and clinical outcomes. METHODS: 147 ESBL-producing E. coli and 82 K. pneumoniae were genetically characterized. Biofilm formation was measured at 1.5, 4, 6, and 24 h during culture in blood heart infusion using a microbead immobilization assay (BioFilm Ring test®). Results were given as biofilm formation index (BFI) with lower values indicating increased presence of biofilm (range = 0-21). RESULTS: In total, 57.1% of strains were strong producers of biofilm (BFI < 2), whereas 13.4% lacked biofilm production (BFI > 18). Standard biofilm production (BFI < 7) was common in E. coli isolates (61.9%). For E. coli, biofilm production was less frequently observed in ST131 clones (p = 0.03) but more frequently in strains harbouring toxin (p = 0.008) or adhesin (p = 0.008) virulence factor genes. Despite almost all K. pneumoniae having standard biofilm production (90.2%), there was a 2.4-times higher odds of observing biofilm in ST29/147/323 versus other ST-types (p = 0.13). Patients with standard biofilm producing isolates were not at increased risk of transfer to intensive-care (odds-ratio=2.80, 95%CI=0.59-13.21) or death within 12-months (odds-ratio=1.61, 95%CI=0.75-3.43). CONCLUSION: In these ESBL-producing strains, biofilm production is linked to certain virulence factors in E. coli and is common in K. pneumoniae. Further exploration of whether biofilm production increases dissemination and risk of severe clinical outcomes is needed in larger collections of isolates.

BACKGROUND: The incidence of Chlamydia trachomatis (Ct) urethritis has been increasing for the past 10 years. There is little data regarding the screening of Ct infection in asymptomatic men in France, despite the national recommendation to screen at-risk asymptomatic men under 30 attending Sexually Transmitted Infections (STI) clinics. Recent data from the French surveillance network Rénachla show indeed that systematic screening is still focused on women. The objective of our study was to determine the prevalence and risk factors for Ct infection in asymptomatic men under 30 attending an STI clinic located in Paris, France. METHODS: We performed a cross-sectional study between April 4, and December 31, 2016 in the database of the software DIAMM Client V8 used in our STI clinic. We extracted the demographic characteristics, sexual behavior and result of STI screening of all asymptomatic men who had consulted and given their consent for the use of their personal data. Those data were collected in usual care through a standardized questionnaire filled in during an appointment with a trained physician. STI screening was performed using PCR kit CT/NG Abbott Realtime® on first void urines. For MSM, a rectal swab was also collected. Risk factors for Ct infection were analyzed by univariate and multivariate modeling using STATA software 8.2. RESULTS: Among 872 men who had attended the clinic, 647 were included and 37 (5.7, 95% CI 4.2 to 7.8) were positive for Ct in urine. In univariate analysis, men who had unprotected sex in the last 6 weeks (OR 2.40 (95%CI 1.16 to 4.94), p = 0.02), and those who had an infected partner (OR 7.6 (95%CI 3.03 to 20), p = 0.0001) were more likely to be infected. In the multivariate analysis having an infected partner was the only risk factor (OR 11.1(95% CI 3.7 to 33.3), p = 0.0001) that remained significant. CONCLUSION: Prevalence of Ct infection is high among asymptomatic men of 30 years or less attending our urban STI clinic especially among those with an infected partner. The Ct screening among this population associated with partner notification, as recommended by the French national guidelines, should be more widely implemented.

BACKGROUND: Assessing the satisfaction of patients about the health care they have received is relatively common nowadays. In France, the satisfaction questionnaire, I-Satis, is deployed in each institution admitting inpatients. Internet self-completion and telephone interview are the two modes of administration for collecting inpatient satisfaction that have never been compared in a multicenter randomized experiment involving a substantial number of patients. OBJECTIVE: The objective of this study was to compare two modes of survey administration for collecting inpatient satisfaction: Internet self-completion and telephone interview. METHODS: In the multicenter SENTIPAT (acronym for the concept of sentinel patients, ie, patients who would voluntarily report their health evolution on a dedicated website) randomized controlled trial, patients who were discharged from the hospital to home and had an Internet connection at home were enrolled between February 2013 and September 2014. They were randomized to either self-complete a set of questionnaires using a dedicated website or to provide answers to the same questionnaires administered during a telephone interview. As recommended by French authorities, the analysis of I-Satis satisfaction questionnaire involved all inpatients with a length of stay (LOS), including at least two nights. Participation rates, questionnaire consistency (measured using Cronbach alpha coefficient), and satisfaction scores were compared in the two groups. RESULTS: A total of 1680 eligible patients were randomized to the Internet group (n=840) or the telephone group (n=840). The analysis of I-Satis concerned 392 and 389 patients fulfilling the minimum LOS required in the Internet and telephone group, respectively. There were 39.3% (154/392) and 88.4% (344/389) responders in the Internet and telephone group, respectively (P<.001), with similar baseline variables. Internal consistency of the global satisfaction score was higher (P=.03) in the Internet group (Cronbach alpha estimate=.89; 95% CI 0.86-0.91) than in the telephone group (Cronbach alpha estimate=.84; 95% CI 0.79-0.87). The mean global satisfaction score was lower (P=.03) in the Internet group (68.9; 95% CI 66.4-71.4) than in the telephone group (72.1; 95% CI 70.4-74.6), with a corresponding effect size of the difference at -0.253. CONCLUSIONS: The lower response rate issued from Internet administration should be balanced with a likely improved quality in satisfaction estimates, when compared with telephone administration, for which an interviewer effect cannot be excluded.

INTRODUCTION: Extra-gastro-intestinal tract manifestations associated with Clostridium difficile infection (CDI), including reactive arthritis (ReA), are uncommon. METHOD: We report a case of ReA associated with a relapse of CDI in a 46-year-old woman. A toxigenic C. difficile strain was isolated from stools and characterized as PCR-ribotype 014/020/077. We conducted a comprehensive literature review of ReA associated with CDI (ReA-CDI). Diagnostic criteria for ReA-CDI were: (i) evidence of aseptic synovitis (confirmed by culture) developing during or immediately after colitis, (ii) presence of a toxigenic C. difficile strain in stool samples, and (iii) absence of other causes of colitis and arthritis. RESULTS: Forty-nine cases of ReA-CDI (excluding the present report) have already been described since 1976. Of these reports, Mean age of patients was 38 years (SD: 18.5), 46% were male, and 68% had HLA B27 genotype. Sixty-nine percent of patients received a ß-lactamin treatment before CDI. ReA-CDI occurred a median 10 days (range 0-55 days) after CDI. Outcome was favorable in 90% of patients and oral non anti-inflammatory drugs were required for 55%. CONCLUSION: ReA-CDI remains uncommon. Compared to the general population, it is more likely observed in younger patients with HLA B27-positive genotype.

OBJECTIVE: Little is known about the effect of gut microbial and extended-spectrum ß-lactamase-producing Enterobacterales (ESBL-E) carriage, particularly in the general population. The aim of this study was to identify microbiota signatures uniquely correlated with ESBL-E carriage. METHODS: We conducted a case-control study among individuals seeking care at the Sexual Health Clinic or Department of Infectious and Tropical Diseases, Saint-Antoine Hospital, Paris, France. Using coarsened exact matching, 176 participants with ESBL-carriage (i.e. cases) were matched 1:1 to those without ESBL-carriage (i.e. controls) based on sexual group, ESBL-E prevalence of countries travelled in <12 months, number of sexual partners in <6 months, geographic origin, and any antibiotic use in <6 months. 16S rRNA gene amplicon sequencing was used to generate differential abundances at the genus level and measures of α- and ß-diversity. RESULTS: Participants were mostly men (83.2%, n = 293/352) and had a median age of 33 years (interquartile range: 27-44). Nine genera were found associated with ESBL-E carriage: Proteus (p < 0.0001), Carnobacterium (p < 0.0001), Enterorhabdus (p 0.0079), Catonella (p 0.017), Dermacoccus (p 0.017), Escherichia/Shigella (p 0.021), Kocuria (p 0.023), Bacillus (p 0.040), and Filifactor (p 0.043); however, differences were no longer significant after Benjamini-Hochberg correction (q > 0.05). There were no differences between those with versus without ESBL-E carriage in measures of α-diversity (Shannon Diversity Index, p 0.49; Simpson Diversity Index, p 0.54; and Chao1 Richness Estimator, p 0.16) or ß-diversity (Bray-Curtis dissimilarity index, p 0.42). DISCUSSION: In this large carefully controlled study, there is lacking evidence that gut microbial composition and diversity is any different between individuals with and without ESBL-E carriage.

BACKGROUND: Liver transplant recipients are at risk of tuberculosis, which is particularly difficult-to diagnose and to treat in this population. METHODS: Retrospective study of all cases of tuberculosis diagnosed from 2007 to 2022 in the French network of liver transplant sites. RESULTS: Twenty-three liver transplant recipients were diagnosed with tuberculosis (six females, median age 59 years [interquartile range, 54-62]), with a median time lapse of 10 months [5-40.5] after transplant, and 38 days [26-60] after symptoms onset. Primary modes of pathogenesis were latent tuberculosis reactivation (n = 15) and transplant-related transmission (n = 3). Even though most patients with pre-transplant data had risk factors for tuberculosis (11/20), IFN-gamma release assay was performed in only three. Most cases involved extra-pulmonary tuberculosis (20/23, 87 %). With median follow-up of 63 months [24-108], five patients died (22 %), including four tuberculosis-related deaths. CONCLUSIONS: Extrapulmonary tuberculosis is a severe disease in liver transplant recipients. Systematic pre-transplant screening of latent tuberculosis may prevent most of them.

Background: Mpox was first reported in France on May 19 and third-generation live Modified Vaccinia Ankara (MVA-BN) vaccination of multiple-partner men who have sex with men (MSM) was recommended as of July 11, 2022. We assessed the impact of vaccination and of sexual behavior adopted during the epidemic period on mpox incidence in the ANRS-174-DOXYVAC trial enrolling MSM on HIV pre-exposure prophylaxis (PrEP) with history of sexually-transmitted infections (STI) in the previous year. Methods: We compared pre-epidemic socio-behavioral characteristics and change in sexual behaviors after the onset of the epidemic of participants with mpox and mpox-free. Then we compared incidence rates of mpox per 1000 person-months (p-m) between May 9-July 10 (before vaccination of MSM, period-1) and July 11-September 20 2022 (after vaccination launch, period-2) and explored factors explaining the period effect using Poisson regression model. Findings: 472 MSM had data before and after May 9, 2022. Twenty percent had received smallpox vaccine during childhood. Mpox occurred in 77/472 participants (incidence 49.3 per 1000 p-m (95% CI 38.9-61.6)). MVA-BN vaccination roll-out was rapid, with 86% (341/398) of eligible participants having received at least one dose by September 20, 2022. Sexual behavior significantly changed before and after May 9, with a decrease in the proportion of mpox-free participants with >10 partners during last 3 months (45% vs 38%, p = 0.0035). Mpox incidence was 67.4 per 1000 p-m (95% CI 51.6-86.6) in period-1, and 24.4 per 1000 p-m (95% CI 13.9-39.6) in period-2, with an incidence rate ratio of 0.36 (95% CI 0.21-0.63). In multivariable Poisson regression model, only MVA-BN vaccination in 2022 remained significantly associated with mpox incidence, with a 99% risk reduction (95% CI 96.6-99.7). Interpretation: In MSM on PrEP enrolled in the ANRS-174-DOXYVAC trial, rapid roll-out of MVA-BN vaccination was associated with a strong reduction in mpox incidence.

RESUMO
Background: The advent of anti-tumor necrosis factor α (anti-TNFα) has revolutionized the treatment of inflammatory bowel disease (IBD). However, susceptibility to active tuberculosis (TB) is associated with this therapy and requires its discontinuation. The risk of immune reconstitution inflammatory syndrome (IRIS) in this population is poorly understood, as is the safety of resuming anti-TNFα. Methods: This French retrospective study (2010-2022) included all TB cases in patients with IBD who were treated with anti-TNFα in 6 participating centers. A systematic literature review was performed on TB-IRIS and anti-TNFα exposure. Results: Thirty-six patients were included (median age, 35 years; IQR, 27-48). TB was disseminated in 86% and miliary in 53%. IRIS occurred in 47% after a median 45 days (IQR, 18-80). Most patients with TB-IRIS (93%) had disseminated TB. Miliary TB was associated with IRIS risk in univariate analysis (odds ratio, 7.33; 95% CI, 1.60-42.82; P = .015). Anti-TB treatment was longer in this population (median [IQR], 9 [9-12] vs 6 [6-9] months; P = .049). Anti-TNFα was resumed in 66% after a median 4 months (IQR, 3-10) for IBD activity (76%) or IRIS treatment (24%), with only 1 case of TB relapse. Fifty-two cases of TB-IRIS in patients treated with anti-TNFα were reported in the literature, complicating disseminating TB (85%) after a median 42 days (IQR, 21-90), with 70% requiring anti-inflammatory treatment. Forty cases of TB-IRIS or paradoxical reaction treated with anti-TNFα were also reported. IRIS was neurologic in 64%. Outcome was mostly favorable (93% recovery). Conclusions: TB with anti-TNFα treatment is often complicated by IRIS of varying severity. Restarting anti-TNFα is a safe and effective strategy.
RESUMO
The emergence of SARS-CoV-2 Omicron variant has led to a complete reconfiguration of the therapeutic landscape, with all monoclonal antibodies having lost any neutralization activity. We report here a case series of 75 immunocompromised patients infected by the Omicron variant who benefited from COVID-19 convalescent plasma (CCP). At Day 28, the overall survival was 76% (95% CI 67-86) with no significant difference in the clinical outcome between patients with hematological malignancies, solid organ transplantation or autoimmune diseases. No safety concern was reported during the course of the study. These results showed that CCP is well tolerated and represents a treatment option for immunocompromised patients who remain highly impacted by the COVID19 epidemic.

BACKGROUND: Increased rates of sexually transmitted infections (STIs) are reported among men who have sex with men (MSM) and new interventions are needed. We aimed to assess whether post-exposure prophylaxis (PEP) with doxycycline could reduce the incidence of chlamydia or syphilis (or both) and whether the meningococcal group B vaccine (4CMenB) could reduce the incidence of gonorrhoea in this population. METHODS: ANRS 174 DOXYVAC is a multicentre, open-label, randomised trial with a 2â×â2 factorial design conducted at ten hospital sites in Paris, France. Eligible participants were MSM aged 18 years or older, HIV negative, had a history of bacterial STIs within the 12 months before enrolment, and who were already included in the ANRS PREVENIR study (a cohort of MSM using pre-exposure prophylaxis with tenofovir and emtricitabine for HIV prevention). Participants were randomly assigned (2:1) to doxycycline PEP (two pills of 100 mg each orally within 72 h after condomless sex, with no more than three doses of 200 mg per week) or no PEP groups and were also randomly assigned (1:1) to the 4CMenB vaccine (GlaxoSmithKline, Paris, France; two intramuscular injections at enrolment and at 2 months) or no vaccine groups, using a computer-generated randomisation list with a permuted fixed block size of four. Follow-up occurred for at least 12 months (with visits every 3 months) up to 24 months. The coprimary outcomes were the risk of a first episode of chlamydia or syphilis (or both) after the enrolment visit at baseline for the doxycycline intervention and the risk of a first episode of gonorrhoea starting at month 3 (ie, 1 month after the second vaccine dose) for the vaccine intervention, analysed in the modified intention-to-treat population (defined as all randomly assigned participants who had at least one follow-up visit). This trial is registered with ClinicalTrials.gov, NCT04597424 (ongoing). FINDINGS: Between Jan 19, 2021, and Sept 19, 2022, 556 participants were randomly assigned. 545 (98%) participants were included in the modified intention-to-treat analysis for the doxycycline PEP and no PEP groups and 544 (98%) were included for the 4CMenB vaccine and no vaccine groups. The median follow-up was 14 months (IQR 9-18). The median age was 40 years (34-48) and all 545 participants were male. There was no interaction between the two interventions (p≥0·1) for the primary outcome. The incidence of a first episode of chlamydia or syphilis (or both) was 8·8 per 100 person-years (35 events in 362 participants) in the doxycycline PEP group and 53·2 per 100 person-years (80 events in 183 participants) in the no PEP group (adjusted hazard ratio [aHR] 0·17 [95% CI 0·12-0·26]; p<0·0001). The incidence of a first episode of gonorrhoea, starting from month 3 was 58·3 per 100 person-years (103 events in 274 participants) in the 4CmenB vaccine group and 77·1 per 100 person-years (122 events in 270 participants) in the no vaccine group (aHR 0·78 [95% CI 0·60-1·01]; p=0·061). There were no deaths during the study. One drug-related serious adverse event (fixed-drug eruption) occurred in the doxycycline PEP group. Six (2%) participants in the doxycycline group discontinued doxycycline PEP because of gastrointestinal adverse events. INTERPRETATION: Doxycycline PEP strongly reduced the incidence of chlamydia and syphilis in MSM, but we did not show efficacy of the 4CmenB vaccine for gonorrhoea. Doxycycline PEP should be assessed in other populations, such as heterosexual men and women, and its effect on antimicrobial resistance carefully monitored.

RESUMO
OBJECTIVES: Positive direct antiglobulin tests (DATs) have been reported in cases of post-artesunate delayed hemolysis (PADH), but the causal role of auto-immune hemolysis remains unclear. We aimed to analyze a cohort of patients with PADH and DAT during severe malaria. METHODS: We describe PADH and DAT results in a 7-year multi-center retrospective cohort of patients receiving artesunate for severe imported malaria. RESULTS: Of 337 patients treated with artesunate, 46 (13.6%) had at least one DAT result within 30 days of treatment initiation, and 25/46 (54.3%) had at least one positive DAT. Among 40 patients with available data, 17 (42.5%) experienced PADH. Patient characteristics were similar for patients with a positive or negative DAT, and DAT positivity was not associated with PADH occurrence (P = 0.36). Among patients, 5/13 (38.5%) with a positive DAT after day 7 experienced PADH, compared to 10/13 (76.9%) of those with a negative DAT after day 7 (P = 0.11). Overall, 41% of patients required blood transfusions, and outcome was favorable without corticosteroids, even in cases of PADH. CONCLUSIONS: DAT does not appear to be a marker of PADH, but rather an indirect marker of an immune-mediated mechanism. DAT positivity should not lead to the administration of systemic corticosteroids during PADH.

BACKGROUND: The optimal treatment regimen for infections caused by wild-type AmpC ß-lactamase-producing Enterobacterales remains controversial. This study compared the outcomes of bloodstream infections (BSI) and pneumonia according to the type of definitive antibiotic therapy: third-generation cephalosporin (3GC), piperacillin ± tazobactam, cefepime or carbapenem. METHODS: All cases of BSI and pneumonia caused by wild-type AmpC ß-lactamase-producing Enterobacterales over 2 years in eight university hospitals were reviewed. Patients who received definitive therapy consisting of either a 3GC (3GC group), piperacillin ± tazobactam (piperacillin group), or cefepime or a carbapenem (reference group) were included in this study. The primary endpoint was 30-day all-cause mortality. The secondary endpoint was treatment failure due to infection by emerging AmpC-overproducing strains. Propensity-score-based models were used to balance confounding factors between groups. RESULTS: In total, 575 patients were included in this study: 302 (52%) with pneumonia and 273 (48%) with BSI. Half (n=271, 47%) received cefepime or a carbapenem as definitive therapy, 120 (21%) received a 3GC, and 184 (32%) received piperacillin ± tazobactam. Compared with the reference group, 30-day mortality was similar in the 3GC [adjusted hazard ratio (aHR) 0.86, 95% confidence interval (CI) 0.57-1.31)] and piperacillin (aHR 1.20, 95% CI 0.86-1.66) groups. The likelihood of treatment failure was higher in the 3GC (aHR 6.81, 95% CI 3.76-12.4) and piperacillin (aHR 3.13, 95% CI 1.69-5.80) groups. The results were similar when stratifying the analysis on pneumonia or BSI. CONCLUSION: Treatment of included BSI or pneumonia caused by wild-type AmpC ß-lactamase-producing Enterobacterales with 3GC or piperacillin ± tazobactam was not associated with higher mortality, but was associated with increased risk of AmpC overproduction leading to treatment failure compared with cefepime or a carbapenem.

OBJECTIVES: Persistent post-acute coronavirus disease 2019 (COVID-19) symptoms (PACSs) have been reported up to 6 months after hospital discharge. Herein we assessed the symptoms that persisted 12 months (M12) after admission for COVID-19 in the longitudinal prospective national French coronavirus disease cohort. METHODS: Hospitalized patients with a confirmed virological diagnosis of COVID-19 were enrolled. Follow-up was planned until M12 after admission. Associations between persistence of ≥3 PACSs at M12 and clinical characteristics at admission were assessed through logistic regression according to gender. RESULTS: We focused on participants enrolled between 24 January 2020 and 15 July 2020, to allow M12 follow-up. The M12 data were available for 737 participants. Median age was 61 years, 475 (64%) were men and 242/647 (37%) were admitted to intensive care units during the acute phase. At M12, 27% (194/710) of the participants had ≥3 persistent PACS, mostly fatigue, dyspnoea and joint pain. Among those who had a professional occupation before the acute phase, 91 out of 339 (27%) were still on sick leave at M12. Presence of ≥3 persistent PACS was associated with female gender, both anxiety and depression, impaired health-related quality of life and Medical Muscle Research Council Scale <57. Compared with men, women more often reported presence of ≥3 persistent PACSs (98/253, 39% vs. 96/457, 21%), depression and anxiety (18/152, 12% vs. 17/268, 6% and 33/156, 21% vs. 26/264, 10%, respectively), impaired physical health-related quality of life (76/141, 54% vs. 120/261, 46%). Women had less often returned to work than men (77/116, 66% vs. 171/223, 77%). CONCLUSIONS: One fourth of the individuals admitted to hospital for COVID-19 still had ≥3 persistent PACSs at M12 post-discharge. Women reported more often ≥3 persistent PACSs, suffered more from anxiety and depression and had less often returned to work than men.
