RESUMO
OBJECTIVES: In this study, we aimed to assess the efficacy of different ways of administration and types of beta-lactams for hospitalized community-acquired pneumonia (CAP). METHODS: In this post-hoc analysis of randomized controlled trials (RCT) on patients hospitalized for CAP (pneumonia short treatment trial) comparing 3-day vs. 8-day durations of beta-lactams, which concluded to non-inferiority, we included patients who received either amoxicillin-clavulanate (AMC) or third-generation cephalosporin (3GC) regimens, and exclusively either intravenous or oral treatment for the first 3 days (followed by either 5 days of oral placebo or AMC according to randomization). The choice of route and molecule was left to the physician in charge. The main outcome was a failure at 15 days after the first antibiotic intake, defined as temperature >37.9°C, and/or absence of resolution/improvement of respiratory symptoms, and/or additional antibiotic treatment for any cause. The primary outcome according to the route of administration was evaluated through logistic regression. Inverse probability treatment weighting with a propensity score model was used to adjust for non-randomization of treatment routes and potential confounders. The difference in failure rates was also evaluated among several sub-populations (AMC vs. 3GC treatments, intravenous vs. oral AMC, patients with multi-lobar infection, patients aged ≥65 years old, and patients with CURB65 scores of 3-4). RESULTS: We included 200 patients from the original trial, with 93/200 (46.5%) patients only treated with intravenous treatment and 107/200 (53.5%) patients only treated with oral therapy. The failure rate at Day 15 was not significantly different among patients treated with initial intravenous vs. oral treatment [25/93 (26.9%) vs. 28/107 (26.2%), adjusted odds ratios (aOR) 0.973 (95% CI 0.519-1.823), p 0.932)]. Failure rates at Day 15 were not significantly different among the subgroup populations. DISCUSSION: Among hospitalized patients with CAP, there was no significant difference in efficacy between initial intravenous and exclusive oral treatment. TRIAL REGISTRATION: This trial is registered with ClinicalTrials.gov, NCT01963442.

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 1âmonth 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 â<â0.0001). 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 852âBAU/ml, respectively, in PWH with CD4 + cell count less than 250 ( n â=â13) and 98% and 1270âBAU/ml for CD4 + greater than 250 ( n â=â64) ( P â=â0.3994). NAbs were present in 73% of PWH with CD4 + less than 250 and 97% of those with CD4 + cell count greater than 250 ( P â=â0.0130). 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 â=â0.0292). CD4 + and CD8 + T-cell counts were unchanged, whereas CD19 + B-cell counts decreased after vaccination(208â±â124 at D0 vs. 188â±â112 at M1, P â<â0.01). 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.

BACKGROUND: Whether integrase strand transfer inhibitors (INSTIs) can decrease HIV-1 DNA levels more rapidly than boosted PIs during primary HIV-1 infection (PHI) is unknown. We hypothesized that once-daily dolutegravir/tenofovir/emtricitabine could reduce the viral reservoir through rapid viral replication control further than once-daily darunavir/cobicistat/tenofovir/emtricitabine. METHODS: The OPTIPRIM2-ANRS 169 study was a randomized (1:1), open-label, multicentre trial in adults with ≤5 or ≤3 HIV antibodies detected, respectively, by western blot or immunoblot in the last 10â days. The primary endpoint was total HIV-1 DNA levels in PBMCs at Week 48 (W48) adjusted for baseline levels. The main secondary endpoint was HIV-1 RNA level decrease. RESULTS: Between April 2017 and August 2018, 101 patients were included from 31 hospitals. Most patients were men (93%), the median age was 36â years and 17% were Fiebig stage ≤3. The median (IQR) plasma HIV-1 RNA and DNA levels were, respectively, 5.8 (5.0-6.6) and 3.87 (3.52-4.15)â log10 copies/million PBMCs. The median (IQR) decreases in HIV-1 DNA levels at W48 were -1.48 (-1.74 to -1.06) and -1.39 (-1.55 to -0.98)â log10 copies/million PBMCs in the dolutegravir and darunavir/cobicistat groups, respectively (Pâ=â0.52). Plasma HIV-1 RNA levels were <50â copies/mL in 24% versus 0% of patients in the dolutegravir and darunavir/cobicistat groups at W4, 55% versus 2% at W8, 67% versus 17% at W12, and 94% versus 90% at W48, respectively. CONCLUSIONS: Dolutegravir-based and darunavir-based regimens initiated during PHI strongly and similarly decreased the blood reservoir size. Considering the rapid viral suppression during a period of high HIV-1 transmission risk, dolutegravir-based regimens are a major first-line option.

Importance: Failure of treatment is the most serious complication in community-acquired pneumonia (CAP). Objective: To assess the potential risk factors for treatment failure in clinically stable patients with CAP. Design, Setting, and Participants: This secondary analysis assesses data from a randomized clinical trial on CAP (Pneumonia Short Treatment [PTC] trial) conducted from December 19, 2013, to February 1, 2018. Data analysis was performed from July 18, 2019, to February 15, 2020. Patients hospitalized at 1 of 16 centers in France for moderately severe CAP who were clinically stable at day 3 of antibiotic treatment were included in the PTC trial and analyzed in the per-protocol trial population. Interventions: Patients were randomly assigned (1:1) on day 3 of antibiotic treatment to receive ß-lactam (amoxicillin-clavulanate [1 g/125 mg] 3 times daily) or placebo for 5 extra days. Main Outcomes and Measures: The main outcome was failure at 15 days after first antibiotic intake, defined as a temperature greater than 37.9 °C and/or absence of resolution or improvement of respiratory symptoms and/or additional antibiotic treatment for any cause. The association among demographic characteristics, baseline clinical and biological variables available (ie, at the first day of ß-lactam treatment), and treatment failure at day 15 among the per-protocol trial population was assessed by univariate and multivariable logistic regressions. Results: Overall, 310 patients were included in the study; this secondary analysis comprised 291 patients (174 [59.8%] male; mean [SD] age, 69.6 [18.5] years). The failure rate was 26.8%. Male sex (odds ratio [OR], 1.74; 95% CI, 1.01-3.07), age per year (OR, 1.03; 95% CI, 1.01-1.05), Pneumonia Severe Index score (OR, 1.01; 95% CI, 1.00-1.02), the presence of chronic lung disease (OR, 1.85; 95% CI, 1.03-3.30), and creatinine clearance (OR, 0.99; 95% CI, 0.98-1.00) were significantly associated with failure in the univariate analysis. When the Pneumonia Severe Index score was excluded to avoid collinearity with age and sex in the regression model, only male sex (OR, 1.92; 95% CI, 1.08-3.49) and age (OR, 1.02; 95% CI, 1.00-1.05) were associated with failure in the multivariable analysis. Conclusions and Relevance: In this secondary analysis of a randomized clinical trial, among patients with CAP who reached clinical stability after 3 days of antibiotic treatment, only male sex and age were associated with higher risk of failure, independent of antibiotic treatment duration and biomarker levels. Another randomized clinical trial is needed to evaluate the impact of treatment duration in populations at higher risk for treatment failure.

We report a case of black-grain eumycetoma co-localized with Mycobacterium tuberculosis infection, presenting as a painless leg abscess and associated with vertebral tuberculosis. The rare association of these two pathogens raises several challenges regarding foreseeable drug interactions, side effects, the most appropriate management, and the potential link between these two diseases.

BACKGROUND: Pyogenic lung abscesses are rare and poorly described infections. This study aimed to describe their prognostic factors. METHODS: We retrospectively included all patients hospitalized between 1 January 1998 and 1 June 2018, with an International Classification of Diseases, version 10 (IDC-10) diagnosis of pyogenic lung abscess, from the Diamm based medical records (Micro6, Nancy, France). Parasitic, fungal, or mycobacterial lung abscesses were excluded. RESULTS: A total of 64 patients were included. Abscesses were associated with immunosuppression in 28 patients, including HIV infection and immunosuppressive therapy for eight and 12 patients, respectively. Bacterial identification was obtained for 36 patients. Nine patients (14%) developed lung abscesses after hematogenous dissemination. They differed from bronchogenic abscesses by their younger age (p = 0.03), the absence of smoking or emphysema (p = 0.05), Staphylococcus aureus (p = 0.001) or Streptococcus spp. (p = 0.05) isolation, and the smaller size of their abscess (p = 0.02). Overall, evolution was marked by radiological sequelae (46.9%), relapse (12.5%), and death (4.8%). Radiological sequelae occurred more frequently during the course of bronchogenic abscesses (p = 0.02), particularly when they spontaneously discharged (p = 0.04). Relapses were more frequent in patients with emphysema (p = 0.04) and when Haemophilus influenzae was isolated (p = 0.04). In multivariate analysis, poor outcomes, including death, sequelae, and relapse occurred more frequently in patients who had bronchogenic abscess (p = 0.02), and in those who received antibiotics during less than 6 weeks (p = 0.05). CONCLUSION: A duration of antibiotic treatment of less than 6 weeks and bronchogenic presentation were globally associated with poor outcome of pyogenic lung abscesses. These data should be considered when proposing guidelines for the care of pyogenic lung abscesses.The reviews of this paper are available via the supplemental material section.

Abdominal tuberculosis (ATB) is uncommon and not very well known by clinicians. We describe the characteristics, evolution, and treatment of patients with ATB in two large hospitals in the Paris region. We reviewed all records of patients treated for ATB, from January 01, 2010 to December 01, 2016, diagnosed by bacteriological and/or histological methods or highly suspected because of clinical/radiological features. We included 80 patients, with a median (IQR) age of 39 (29-50) years, with 56.2% being males. Among them, 63.7% had African origins, 15% Asian, and 11.2% European. Twenty-nine had a cause of immunosuppression (n = 21 HIV infection). The main abdominal localizations were lymph nodes (72.5%), peritoneum (62.5%), and solid organs (25%). Extra-abdominal localizations were recorded in 65 (81.2%) patients. Tuberculosis was proven bacteriologically in 71%, histologically in 50%, and solely clinical/radiological in 10% of cases. Patients received standard therapy for a median duration of 9 months, with a favorable outcome. Corticosteroid therapy was used in 15 cases, either for paradoxical reaction or to prevent complications. Abdominal TB was mainly represented by lymphatic and peritoneal localizations, proven bacteriologically, and associated with extra-abdominal localizations in most cases. The use of steroids remains controversial, but it does not seem systematically needed in case of abdominal involvement.

BACKGROUND: HIV, HBV and HCV infections continue to represent major health concerns, especially among key at-risk populations such as men who have sex with men (MSM), people who inject drugs (PWIDs), transgender women (TGW) and sex workers (SW). The objective of the ANRS-CUBE study was to evaluate the acceptability of a healthcare, community-based strategy offering a triple rapid HIV-HBV-HCV testing, and HBV vaccination, targeted at three priority groups (MSM, PWIDs and TGW/SWs), in three community centers, in the Paris area. METHODS: This longitudinal multicentric non-randomized study included all adult volunteers attending one of the three specialized community centers in Paris, between July 2014 and December 2015. HIV, HBV and HCV status and acceptability of HBV vaccination were evaluated. RESULTS: A total of 3662, MSM, 80 PWIDs and 72 TGW/SW were recruited in the three centers respectively. Acceptability of rapid tests was 98.5% in MSM and 14.9% in TGW/SWs, but could not be estimated in PWIDs since the number of users attending and the number of proposals were not recorded. User acceptability of HBV vaccination was weak, only 17.9% of the eligible MSM (neither vaccinated, nor infected) agreed to receive the first dose, 12.2% two doses, 5.9% had a complete vaccination. User acceptability of HBV vaccination was greater in PWIDs and TGW/SWs, but decreased for the last doses (66.7 and 53.3% respectively received a first dose, 24.4 and 26.7% a second dose and 6.7 and 0% a third dose). Fifty-three participants (49 MSM and 4 PWIDs) were discovered HIV positive, more than half with a recent infection. All but two HIV positive participants were linked to appropriate care in less than one month. CONCLUSIONS: Rapid HIV-HCV-HBV screening showed a very high level of acceptability among MSM. Efforts need to be made to improve immediate acceptability for HBV vaccination, especially among MSM, and follow-up doses compliance. Our results show the important role of community centers in reaching targets, often fragile, populations, while also suggesting the need to reinforce on-site human support in terms of testing and vaccination, especially when addressing PWIDs.

BACKGROUND: Several studies have shown that NNRTI/PI-based triple therapy could be safely administered as a 4 days (4D) or 5 days (5D) a week maintenance strategy. We report here our experience of using an integrase inhibitor (INSTI)-based 4D/5D regimen in virologically suppressed HIV patients. METHODS: This cohort study enrolled adult patients on ART with viral load (VL) <50 copies/mL for >1 year, who switched to an INSTI-based triple regimen given 4D/5D a week. The primary endpoint was the virological efficacy rate at Week (W) 48, with virological failure defined as confirmed VL ≥50 copies/mL. RESULTS: A total of 73 patients were included (n = 28 for 4D, n = 45 for 5D): 54 men (74%), median (IQR) age 51 (45-57) years, ART duration 10 (6-18) years and duration of viral suppression 5 (2-9) years at baseline. As of 25 March 2019, the median follow-up was 21 (14-35) months, with a total of 161 patient-years of follow-up; all patients had reached the W24 visit, 66 (90%) W48 and 34 (47%) W96. Four patients discontinued the strategy: virological failure (n = 2) at W60 and W67, respectively, switch for renal toxicity (n = 1) at W28 and switch to rilpivirine/dolutegravir (n = 1) at W65. Overall the rate of virological success (95% CI) was 100% (94%-100%) at W24 and W48 and 93.7% (79.8%-98.2%) at W96. CONCLUSIONS: While waiting for the final results of the large randomized QUATUOR ANRS-170 study, our real-life results suggest that the use of an intermittent maintenance triple-drug regimen given as a weekend (2 or 3 days) off is as effective with an INSTI-based regimen as with a PI or an NNRTI.

OBJECTIVES: Molecular epidemiology is applied to various aspects of HIV transmission analyses. With ultradeep sequencing (UDS), in-depth characterization of transmission episodes involving minority variants is permitted. We explored HIV-1 epidemiological linkage and evaluated characteristics of transmission dynamics and transmitted drug resistance (TDR) detection through the added value of UDS. DESIGN: HIV pol gene fragments were sequenced by UDS and Sanger sequencing on samples of 70 HIV-1-infected, treatment-naive recently diagnosed MSM. METHODS: Pairwise genetic distances and maximum likelihood phylogenies were computed. Transmission events were identified as clades with branch support at least 70% and intraclade genetic difference less than 4.5%. TDR mutations were recognized from the TDR consensus list. Transmission directionality, directness and inoculum size were inferred from tree topologies. RESULTS: Both datasets concurred in the identification of seven transmission pairs and one cluster of three patients. With UDS, direction of transmission was inferred in four out of eight chains. Evidence for multiple founder viruses was found in two out of eight chains. No transmission of minority-resistant variants was evidenced. TDR mutations prevalence in protease and reverse transcriptase fragments was 4.3% with Sanger sequencing and 18.6% with UDS. CONCLUSION: Although Sanger sequencing and UDS identified the same transmission chains, UDS provided additional information on founder viruses, direction of transmission and levels of TDR. Nevertheless, topology of clusters was not always consistent across gene fragments, calling for a cautious interpretation of the data. Moreover, unobserved intermediary links cannot be excluded. Phylogenetic analysis use as a forensic technique for HIV transmission investigations is risky.

Background: Infections caused by multidrug-resistant organisms (MDRO) are emerging worldwide. Physicians are increasingly faced with the question of whether patients need empiric antibiotic treatment covering these pathogens. This question is especially essential among MDRO carriers. We aim to determine the occurrence of MDRO bacteraemia among bacteraemic patients colonized with MDRO, and the associated factors with MDRO bacteraemia among this population. Methods: We performed a retrospective monocentric study among MDRO carriers hospitalized with bacteraemia between January 2013 and August 2016 in a French hospital. We compared characteristics of patients with MDRO and non-MDRO bacteraemia. Results: Overall, 368 episodes of bacteraemia were reviewed; 98/368 (26.6%) occurred among MDRO carriers.Main colonizing bacteria were extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (40/98; 40.8%), ESBL-producing Klebsiella pneumoniae (35/98; 35.7%); methicillin-resistant Staphylococcus aureus (26/98; 26.5%) and multidrug-resistant Pseudomonas aeruginosa (PA) (12/98; 12.2%).There was no significant difference considering population with MDRO bacteraemia vs. non-MDRO bacteraemia, except for immunosuppression [OR 2.86; p = 0.0207], severity of the episode [OR 3.13; p = 0.0232], carriage of PA [OR 5.24; p = 0.0395], and hospital-acquired infection [OR 2.49; p = 0.034].In the multivariate analysis, factors significantly associated with MDRO bacteraemia among colonized patient were only immunosuppression [OR = 2.96; p = 0.0354] and the hospital-acquired origin of bacteraemia [OR = 2.62; p = 0.0427]. Conclusions: According to our study, occurrence of bacteraemia due to MDRO among MDRO carriers was high. Factors associated with MDRO bacteraemia were severity of the episode and hospital-acquired origin of the bacteraemia. Thus, during bacteraemia among patients colonized with MDRO, if such characteristics are present, broad-spectrum antimicrobial treatment is recommended.

INTRODUCTION: Urinary tract infections (UTI) are a major public health problem among spinal cord injury (SCI) patients. They frequently involve multidrug-resistant (MDR) bacteria. Ceftolozane/tazobactam (C/T) is a novel antibiotic combination approved for complicated intra-abdominal and UTI caused by Gram-positive and Gram-negative organisms, including some MDR strains. Little is known about the use of this agent for complicated febrile UTI occurring among SCI patients with neurogenic bladder due to MDR Pseudomonas aeruginosa (PSA). CASE PRESENTATION: We describe the case of a 35-year-old man with SCI due to multiple sclerosis, with a neurogenic bladder necessitating a bilateral nephrostomy and double J catheter, who developed a febrile UTI due to a MDR PSA, which was susceptible only to amikacin and colistin. Because of this MDR phenotype and the underlying kidney disease, a 1000 mg (1000 mg per 500 mg) dose of C/T was given as monotherapy every 8 h for 7 days, after 3 days of colistin and amikacin. Thanks to this treatment, the patient had a favorable outcome with no clinical signs of UTI or positive urine culture up to 1 month after diagnosis. DISCUSSION: C/T seems to be an effective and safe therapeutic option for febrile UTI due to MDR PSA in SCI patients with neurogenic bladder, even when administered in monotherapy for 10 days.

A case of severe glandular tularemia in a patient receiving anti-tumour necrosis factor (TNF) therapy is reported here. The patient required prolonged treatment with doxycycline-ciprofloxacin due to early relapse after ciprofloxacin was stopped. Tularemia may have a more severe course in patients receiving anti-TNF. This may thus be an indication for more aggressive treatment.

Objectives: To determine whether aztreonam is still an effective drug for the treatment of gonorrhoea. Methods: Observational study of patients with gonorrhoea diagnosed by urine multiplex PCR, with a past medical history of allergy to ß-lactams or relapse after treatment with a third-generation cephalosporin. Patients received a single 1 g dose of aztreonam in accordance with the manufacturer's instructions. Results: Five patients (four males, one female) were enrolled, comprising two who were allergic to ß-lactams and three previously treated with cephalosporins who relapsed. Median age was 38 years (range 23-51). Following treatment with aztreonam all were cured without any adverse event. All the men were free of symptoms, and the woman tested negative for gonorrhoea 1 month after treatment. Conclusion: Aztreonam appears to be an effective alternative to cephalosporins in the treatment of uncomplicated gonorrhoea, particularly when patients are suspected of being infected by strains with reduced susceptibility to ceftriaxone or are known to be allergic to penicillin.

The use of antibiotics, as any other drug, is regulated by the terms of its marketing authorisation, notified in the Summary of Product Characteristics (SPC). If a prescription is not in accordance with the SPC, the physician prescribes off-label. There is very little literature regarding off-label use of antibiotics in adult healthcare facilities. A prospective monocentric study was conducted during 11 days from February to June 2015 in hospitalised patients from a tertiary teaching hospital with a high prevalence of multidrug-resistant organism colonisation to evaluate off-label use of antibiotics. Two independent experts assessed whether prescriptions complied with the latest guidelines in infectious diseases and whether off-label use of antibiotics was associated with an increased risk of adverse events. In total, 160 antibiotic prescriptions were analysed, of which 76 (47.5%) were off-label. Of the 76 off-label prescriptions, 50 (65.8%) were off-label regarding indications and 26 (34.2%) regarding doses. Nevertheless, 46/50 off-label indications (92.0%) and only 14/26 off-label doses (53.8%) were approved by experts, especially because of dose adjustment requirements. During follow-up, the rate of reported adverse events was not statistically different between patients with (n = 76) and without (n = 84) off-label prescriptions (P = 0.35). In a context of multidrug resistance and a lack of new drugs, high rates (47.5%) of antibiotic off-label use were observed in our hospital, but without an increased rate of adverse events. Moreover, 78.9% of off-label uses were in accordance with guidelines. Therefore, the SPC is not the warrant of an appropriate use of antibiotics.
