RESUMEN
BACKGROUND: The HOME-CoV (Hospitalisation or Outpatient ManagEment of patients with SARS-CoV-2 infection) score is a validated list of uniquely clinical criteria indicating which patients with probable or proven COVID-19 can be treated at home. The aim of this study was to optimise the score to improve its ability to discriminate between patients who do and do not need admission. METHODS: A revised HOME-CoV score was derived using data from a previous prospective multicentre study which evaluated the original Home-CoV score. Patients with proven or probable COVID-19 attending 34 EDs in France, Monaco and Belgium between April and May 2020 were included. The population was split into a derivation and validation sample corresponding to the observational and interventional phases of the original study. The main outcome was non-invasive or invasive ventilation or all-cause death within 7 days following inclusion. Two threshold values were defined using a sensitivity of >0.9 and a specificity of >0.9 to identify low-risk and high-risk patients, respectively. The revised HOME-CoV score was then validated by retrospectively applying it to patients in the same EDs with proven or probable COVID-19 during the interventional phase. The revised HOME-CoV score was also tested against original HOME-CoV, qCSI, qSOFA, CRB65 and SMART-COP in this validation cohort. RESULTS: There were 1696 patients in the derivation cohort, of whom 65 (3.8%) required non-invasive ventilation or mechanical ventilation or died within 7 days and 1304 patients in the validation cohort, of whom 22 (1.7%) had a progression of illness. The revised score included seven clinical criteria. The area under the curve (AUC) was 87.6 (95% CI 84.7 to 90.6). The cut-offs to define low-risk and high-risk patients were <2 and >3, respectively. In the validation cohort, the AUC was 85.8 (95% CI 80.6 to 91.0). A score of <2 qualified 73% of patients as low risk with a sensitivity of 0.77 (0.55-0.92) and a negative predictive value of 0.99 (0.99-1.00). CONCLUSION: The revised HOME-CoV score, which does not require laboratory testing, may allow accurate risk stratification and safely qualify a significant proportion of patients with probable or proven COVID-19 for home treatment.

BACKGROUND: We aimed to identify patients at low risk of bloodstream infection (BSI) in the ED. METHODS: We derived and validated a prediction model to rule out BSI in the ED without the need for laboratory testing by determining variables associated with a positive blood culture (BC) and assigned points according to regression coefficients. This retrospective study included adult patients suspected of having BSI (defined by at least one BC collection) from two European ED between 1 January 2017 and 31 December 2019. The primary end point was the BSI rate in the validation cohort for patients with a negative Bacteremia Rule Out Criteria (BAROC) score. The effect of adding laboratory variables to the model was evaluated as a second step in a two-step diagnostic strategy. RESULTS: We analysed 2580 patients with a mean age of 64 years±21, of whom 46.1% were women. The derived BAROC score comprises 12 categorical clinical variables. In the validation cohort, it safely ruled out BSI without BCs in 9% (58/648) of patients with a sensitivity of 100% (95% CI 95% to 100%), a specificity of 10% (95% CI 8% to 13%) and a negative predictive value of 100% (95% CI 94% to 100%). Adding laboratory variables (creatinine ≥177 µmol/L (2.0 mg/dL), platelet count ≤150 000/mm3 and neutrophil count ≥12 000/mm3) to the model, ruled out BSI in 10.2% (58/570) of remaining patients who had been positive on the BAROC score. The BAROC score with laboratory results had a sensitivity of 100% (95% CI 94% to 100%), specificity of 11% (95% CI 9% to 14%) and negative predictive value of 100% (95% CI 94 to 100%). In the validation cohort, there was no evidence of a difference in discrimination between the area under the receiver operating characteristic for BAROC score with versus without laboratory testing (p=0.6). CONCLUSION: The BAROC score safely identified patients at low risk of BSI and may reduce BC collection in the ED without the need for laboratory testing.

The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) highlights the importance of rapid diagnostic testing to identify individuals with SARS-CoV-2 infections and to limit the spread of the virus. Many molecular assays have become commercially available to cope with this surging demand for timely diagnosis of COVID-19 cases, but identifying individuals requires accurate diagnostic tools. We compared the performance of three molecular SARS-CoV-2 assays: Aptima™ SARS-CoV-2 assay running on the Panther system (Hologic), an in-house assay (Laboratory Developed Test, LDT) running on the Fusion module of the Panther Fusion system (LDT-Fusion; Hologic), and the R-GENE® SARS-CoV-2 assay (bioMérieux). In addition, we also evaluated the turnaround time. This parameter is crucial to managing the SARS-CoV-2 diagnosis and represents a key point in the quality management at the laboratory. Aptima™ and LDT-Fusion assays exhibited an excellent positive percent agreement (PPA) (100.0%), while the R-GENE® assay showed a slightly decreased PPA (98.2%). The Hologic assays have a higher throughput with less hands-on time than the R-GENE® assays (24-25 vs. 71 min). Both Hologic assays are used on a fully automated random-access testing system with on-demand testing capabilities that avoid run series, unlike the R-GENE® assay. Automated random-access testing systems should be preferred during periods of high SARS-CoV-2 prevalence.

BACKGROUND: Cat scratch disease frequently involves a benign, self-limited disease. Neurological forms associated with Bartonella henselae are uncommon, consisting mostly in neuroretinitis, encephalitis and meningitis. Cerebral epidural empyema has never described. CASE PRESENTATION: An adult patient was hospitalized for isolated headaches. Magnetic Resonance Imaging (MRI) identified typical features of cerebral epidural empyema. The diagnosis of B. henselae was performed incidentally by 16S rDNA gene sequencing on the abscess fluid, and confirmed by specific qPCR. We report here the first case, to our knowledge, of cerebral epidural empyema associated with B. henselae. Further follow-up visits allowed identifying frequent cat scratches on the scalp as the presumptive source of infection. CONCLUSIONS: This case report alerts about such atypical clinical presentation, which requires an extensive clinical investigation. It also emphasizes on the usefulness of additional molecular diagnosis techniques in such CNS infection cases.

Severe acute respiratory syndrome coronavirus 2, the coronavirus with respiratory tropism responsible for COVID-19, was isolated for the first time in China at the end of 2019. Several months after its discovery and despite its pandemic spread, there are still many grey areas concerning the pathophysiology and treatment of COVID-19. However, we have strong data on its epidemiological characteristics and the clinical expression of this disease is now well described.

Our objective was to assess the effectiveness of a multiplex PCR panel for blood culture identification (BCID2) on the implementation of appropriate antimicrobial therapy. We conducted a monocentric pre/post study comparing the time to result from direct microscopic examination (DE) to bacterial identification (BI) in positive blood cultures between 2 different periods: P1 without BCID2 and P2 with BCID2. Appropriate treatments prescribed before DE and after DE / BCID2 and after BI / BCID2 were compared using direct proportion comparison and survival analysis. For mono-microbial bloodstream infections, the proportion of appropriate antimicrobial treatment after DE was 50% in P1 vs. 87.5% after BCID2 in P2 (P < 0.001) for Gram-negative bacteria and 33.0% in P1 vs. 64.4% in P2 (P < 0.01) for Gram-positive bacteria. A significant difference (P = 0.04) was recorded with survival curves for Gram positive bacteria. BCID2 seems effective in reducing the time for prescribing appropriate antimicrobials.

BACKGROUND: Unique blood culture (UBC) has been proposed to limit the number of venipuncture and to decrease the risk of BC contaminations (BCC) without affecting their yield. We hypothesized that a multi-faceted program based on UBC in the ICU may reduce the rate of contaminants with a similar performance for bloodstream infections (BSI) identification. METHODS: In a before and after design, we compared the proportion of BSI and BCC. A first 3-year period with multi-sampling (MS) strategy followed by a 4-month washout period, where staff received education and training for using UBC, and a 32-month period, where UBC was routinely used, while education and feedback were maintained. During the UBC period, a large volume of blood (40 mL) was sampled through a unique venipuncture with additional BC collections discouraged for 48 h. RESULTS: Of the 4,491 patients included (35% female patients, mean age 62 years) 17,466 BC were collected. The mean volume of blood per bottle collected increased from 2.8 ± 1.8 mL to 8.2 ± 3.9 mL between the MS and UBC periods, P < 0.01. A 59.6% reduction (95% CI 56.7-62.3; P < 0.001) of BC bottles collected per week was observed between the MS and UBC periods. The rate of BCC per patient decreased between the two periods from 11.2% to 3.8% (73.4% reduction; P < 0.001) for the MS and UBC periods, P < 0.001. Meanwhile, the rate of BSI per patient remained stable at 13.2% and 13.2% for the MS and UBC periods, P = 0.98. CONCLUSIONS: In ICU patients, a strategy based on UBC reduces the contamination rate of cultures without affecting their yield.

Despite susceptibility testing, recurrent infections are common and are associated with resistance. Using whole-genome sequencing, Stracy et al. demonstrated that recurrence is often driven by a different strain than the original infection. By machine-learning analysis, they developed an algorithm for patient-specific recommendations to minimize antimicrobial resistance (AMR) at the individual-patient level.

INTRODUCTION: Point-of-care ultrasonography (POCUS) has emerged as an essential supplement to physical examination in many specialties. In contrast, its use by infectious diseases (ID) specialists remains anecdotal. Here, we report on the acquisition of an ultrasonography device in a French ID ward, and we describe its everyday use. METHODS: A preliminary audit was conducted to evaluate the potential impact of the acquisition of an ultrasonography device. A second audit was performed during the first year following the acquisition of the device to quantify its everyday use. We also evaluated the impact of POCUS implementation on medical imaging requests by comparing the number of intra-hospital transports before and after the acquisition. RESULTS: According to the first audit, 81 of the 199 (41%) imaging examinations that were prescribed during a two-month period could have been replaced by POCUS. During the first year following the acquisition of the ultrasonography device, POCUS was performed 240 times by 31 different operators. The operators were a senior physician, an intern, and a medical student in 94 (39%), 135 (57%), and 11 (5%) cases, respectively. The organs most frequently explored were the genito-urinary tract (n=74), the joints (n=35), and the lungs/pleura (n=35). Acquisition of the device was followed by a significant decrease in the number of transports to the ultrasonography room, whereas the total number of transports to the medical imaging ward did not change. CONCLUSION: Opportunities to use POCUS in the ID ward are numerous. POCUS training should be part of the ID specialist's curriculum.

Background: Streptomyces are environmental gram-positive bacilli that can cause ubiquitous mycetoma and, more rarely, invasive infections. We describe the clinical relevance of Streptomyces spp. identified in human samples and characteristics of patients with invasive Streptomyces infections. Methods: We conducted a retrospective (2006-2017) study of Streptomyces isolates identified in clinical samples in French microbiology laboratories. Streptomyces genus was confirmed by a specific 16S rRNA polymerase chain reaction, and antibiotic susceptibility testing was performed by disk diffusion and trimethoprim-sulfamethoxazole minimum inhibitory concentration (E-test) if resistance was suspected. Patient characteristics, treatments, and outcomes were collected. Invasive infection was defined as a positive culture from a sterile site with signs of infection but without cutaneous inoculation. Results: Of 137 Streptomyces isolates, all were susceptible to amikacin (113/113) and linezolid (112/112), and 92.9% to imipenem (105/113). Using disk diffusion, 50.9% (57/112) of isolates were susceptible to trimethoprim-sulfamethoxazole, but most of the apparently resistant isolates (25/36, 69.4%) tested by E-test were ultimately classified as susceptible. Clinical data were obtained for 63/137 (45.9%) isolates: 30 (47.6%) invasive infections, 8 (12.7%) primary cutaneous infections, 22 (34.9%) contaminations, 3 (4.7%) respiratory colonization. Patients with invasive infection were more frequently receiving corticosteroids than patients without invasive infection (11/30, 36.7%, vs 2/25, 8.0%; P = .03), and at 6-month follow-up, 14 of them were cured, 3 had relapsed, 4 were dead, and 9 were lost to follow-up. Conclusions: Half of the clinical samples that grew Streptomyces were from patients with invasive infection. In that case, antimicrobial therapy should include 1 or 2 antibiotics among linezolid, amikacin, or imipenem.
RESUMEN
CASE PRESENTATION: A 78-year-old woman was admitted to the ED with a 10-day history of diarrhea and recent onset of dry cough, fever, and asthenia. She had a medical history of obesity (BMI 32) and arterial hypertension treated with irbesartan. In the context of a large-scale lockdown in France during the COVID-19 pandemic, she only had physical contact with her husband, who did not report any symptoms. She required mechanical ventilation because of severe hypoxemia within 1 hour after admission to the ED.

BACKGROUND: Gut colonization by ESBL-producing Enterobacteriaceae (ESBL-PE) is widespread and is promoted by antibiotic exposure. Higher fecal abundance of ESBL-PE promotes the dissemination of the bacteria in the environment and is associated with increased risk of infection. Ceftriaxone and temocillin are commonly used antibiotics with a different activity on gut flora. Their impact on fecal abundance of ESBL-producing Enterobacteriaceae has not been studied. The objective of this study was to compare the propensity of ceftriaxone and temocillin to modify the abundance of ESBL-producing Escherichia coli in feces of colonized mice. METHODS: Mice received broad-spectrum antibiotics in order to disrupt their normal gut flora. A CTX-M-type ESBL-producing E. coli clinical isolate was then administered orally, leading to durable colonization. Thirty days later, mice received either temocillin or ceftriaxone with drinking water at a concentration simulating human intestinal exposure. Third-generation-cephalosporin resistant (3GCR) E. coli were enumerated in feces on selective medium before, 2 days and 10 days after the end of antibiotic exposure. The experiment was performed with two E. coli isolates with different temocillin minimum inhibitory concentrations. RESULTS: Exposure to ceftriaxone induced an increase in the fecal abundance of 3GCR E. coli. In contrast, temocillin had no effect or transiently decreased the number of 3GCR E. coli. Results obtained with the two strains were similar. CONCLUSION: Contrary to ceftriaxone, temocillin does not promote expansion of ESBL-producing E. coli in feces of colonized mice. Thus temocillin may be a therapeutic of choice when a temocillin-susceptible strain infection is suspected or proven to prevent the expansion of ESBL-PE in a previously colonized patient.

BACKGROUND: Severely ill patients with SARS-CoV-2 have an increased risk of venous thromboembolism (VTE) i.e., deep vein thrombosis and pulmonary embolism. However, the VTE risk in patients with mild and moderate COVID-19, hospitalized or managed at home, remain uncertain. The aims of this study were to assess the rate and the risk factors symptomatic VTE, in patients with mild and moderate COVID-19 and to compare them to a cohort of similar patients without COVID-19. METHODS: Patients presenting to the emergency department (ED) of participating centers for confirmed or probable mild or moderate COVID-19 and not having acute VTE were included. This COVID-19 cohort was retrospectively compared to a prospective cohort of similar ED patients using propensity score matching. The main outcome was the rate of symptomatic VTE within the 28 days after ED presentation. RESULTS: A total of 2292 patients were included in the COVID-19 cohort. The 28-day incidence of symptomatic VTE was 1.3% (n = 29/2292, 95%CI: 0.9 to 1.8), 2.3% (n = 20/866, 95%CI: 1.5 to 3.5) in moderate COVID-19 patients and 0.6% (n = 9/1426; 95%CI: 0.3 to 1.2) in mild COVID-19 patients managed as outpatients. An age over 65 years and hospitalization were independent risk factors of VTE. After adjustment, patients in the COVID-19 cohort had an absolute increase in over symptomatic VTE risk of +1.69% (95%CI, 0.88 to 2.51) versus patients in the comparison cohort (n = 1539). CONCLUSIONS: Patients with moderate COVID-19 presenting to the ED had a high risk of subsequent VTE. TRIAL REGISTRATION: Ethics committee of the CHU of Angers (N°2020/87).

BACKGROUND: The Hospitalization or Outpatient Management of Patients With SARS-CoV-2 Infection (HOME-CoV) rule is a checklist of eligibility criteria for home treatment of patients with COVID-19, defined using a Delphi method. RESEARCH QUESTION: Is the HOME-CoV rule reliable for identifying a subgroup of COVID-19 patients with a low risk of adverse outcomes who can be treated at home safely? STUDY DESIGN AND METHODS: We aimed to validate the HOME-CoV rule in a prospective, multicenter study before and after trial of patients with probable or confirmed COVID-19 who sought treatment at the ED of 34 hospitals. The main outcome was an adverse evolution, that is, invasive ventilation or death, occurring within the 7 days after patient admission. The performance of the rule was assessed by the false-negative rate. The impact of the rule implementation was assessed by the absolute differences in the rate of patients who required invasive ventilation or who died and in the rate of patients treated at home, between an observational and an interventional period after implementation of the HOME-CoV rule, with propensity score adjustment. RESULTS: Among 3,000 prospectively enrolled patients, 1,239 (41.3%) demonstrated a negative HOME-CoV rule finding. The false-negative rate of the HOME-CoV rule was 4 in 1,239 (0.32%; 95% CI, 0.13%-0.84%), and its area under the receiver operating characteristic curve was 80.9 (95% CI, 76.5-85.2). On the adjusted populations, 25 of 1,274 patients (1.95%) experienced an adverse evolution during the observational period vs 12 of 1,274 patients (0.95%) during the interventional period: -1.00 (95% CI, -1.86 to -0.15). During the observational period, 858 patients (67.35%) were treated at home vs 871 patients (68.37%) during the interventional period: -1.02 (95% CI, -4.46 to 2.26). INTERPRETATION: A large proportion of patients treated in the ED with probable or confirmed COVID-19 have a negative HOME-CoV rule finding and can be treated safely at home with a very low risk of complications.

We report a high prevalence (28%) of sink drains contaminated with carbapenemase-producing Enterobacteriaceae (CPE) in 4 intensive care units with a history of CPE carriage in hospitalized patients within the previous 5 years, but apart from any current epidemic context. Carbapenemase genes, particularly blaVIM and blaNDM, were identified by polymerase chain reaction in sink drains in which no CPE was detected, but very few data are available in the literature concerning their presence in sink drains.

OBJECTIVES: Pasteurella bacteraemia is rare, but has been associated with a high mortality rate. The aim of this study was to estimate the impact of comorbidities on patients with Pasteurella bacteraemia. METHODS: All cases of Pasteurella bacteraemia in adults treated in our centre between January 2008 and December 2017 were included retrospectively and compared with cases identified in a systematic review of the literature via MEDLINE covering the years 1951-2017. The epidemiological, bacteriological, and clinical data were collected, as well as the instances of death after 30 days. RESULTS: Twenty cases of Pasteurella bacteraemia identified in our centre and 99 cases from the literature review were included. A major comorbidity was found in 80/119 (67.2%) patients. The death rate at 30 days was 31.1%. The most common comorbidities were cirrhosis, immunosuppressive therapy, and malignant diseases. Age was not associated with mortality. On multivariate analysis, the only factor associated with mortality was a major comorbidity (odds ratio 2.78, 95% confidence interval 1.01-7.70; p = 0.04). CONCLUSIONS: This study confirms the high mortality rate and highlights the importance of the host background, independent of age, in Pasteurella bacteraemia. Clinicians should be aware of the comorbidities in cases of Pasteurella infection, due to the poor prognosis of bacteraemia.

In the context of the COVID-19 pandemic and overloaded hospitals, a central issue is the need to define reliable and consensual criteria for hospitalization or outpatient management in mild cases of COVID-19. Our aim was to define an easy-to-use clinical rule aiming to help emergency physicians in hospitalization or outpatient management decision-making for patients with suspected or confirmed SARS-CoV-2 infection (the HOME-CoV rule). The Delphi method was used to reach a consensus of a large panel of 51 experts: emergency physicians, geriatricians, infectious disease specialists, and ethical consultants. A preliminary list of eligible criteria was compiled based on a literature review. Four rounds of anonymized expert consultations were performed. The experts were asked to score each item as relevant, possibly relevant and non-relevant, as major or minor, and to choose the cut-off. They were also able make suggestions and remarks. Eight criteria constituting the HOME-CoV were selected: six correspond to the severity of clinical signs, one to the clinical course (clinically significant worsening within the last 24 h), and the last corresponds to the association of a severe comorbidity and an inadequate living context. Hospitalization is deemed necessary if a patient meets one or more of the criteria. In the end, 94.4% of the experts agreed with the defined rule. Thanks to the Delphi method, an absolute consensus was obtained of a large panel of experts on the HOME-CoV rule, a decision-making support mechanism for clinicians to target patients with suspected or confirmed COVID-19 requiring hospitalization.Trial registration: NCT04338841.
