ABSTRACT
BACKGROUND: The 2023 Duke-ISCVID (International Society of Cardiovascular Infectious Diseases) classification is a new diagnostic tool for infective endocarditis, updating the 2000 modified Duke and the 2015 European Society for Cardiology (ESC) classifications. In comparison, its sensitivity is higher; however, its specificity remains to be evaluated and compared to that of the 2 other classifications in endocarditis suspected patients. METHODS: We retrospectively collected the characteristics of patients hospitalized in Bichat University's Hospital, Paris, in 2021, who had been evaluated for clinical suspicion of endocarditis, have had at least a transthoracic echocardiography, 2 pairs of blood cultures, 3-month follow-up and in whom endocarditis diagnosis was finally rejected. All patients were classified by 2000 modified Duke, 2015 ESC and 2023 Duke-ISCVID, as though the endocarditis diagnosis had not been rejected. RESULTS: In total, 130 patients' charts were analyzed. Mean age was 62 years, 84 (64.6%) were male, 39 (30.0%) had prosthetic cardiac valve or valve repair, 21 (16.2%) cardiac implanted electronic device, and 30 (23.1%) other cardiac conditions. Overall, 5, 2, and 5 patients were falsely classified as definite endocarditis with the 2000 modified Duke, 2015 ESC, and 2023 Duke-ISCVID classifications, respectively. The corresponding specificities were 96.2% (95% confidence interval [CI] [90.8%, 98.6%]), 98.5% (95% CI [93.9%, 99.7%]), and 96.2% (95% CI [90.8%, 98.6%]). The rates of possible endocarditis were of 38%, 35%, and 35% in the 3 classifications, respectively. CONCLUSIONS: The 2023 Duke-ISCVID classification is highly specific for ruling out the diagnosis of definite infective endocarditis in patients who had been evaluated for IE.

BACKGROUND: The 2023 Duke-International Society for Cardiovascular Diseases (ISCVID) criteria for infective endocarditis (IE) were proposed as an updated diagnostic classification of IE. Using an open prospective multicenter cohort of patients treated for IE, we compared the performance of these new criteria to that of the 2000 Modified Duke and 2015 European Society of Cardiology (ESC) criteria. METHODS: Cases of patients treated for IE between January 2017 and October 2022 were adjudicated as certain IE or not. Each case was also categorized as either definite or possible/rejected within each classification. Sensitivity, specificity, and accuracy were estimated with 95% confidence intervals. RESULTS: Of the 1194 patients analyzed (mean age, 66.1 years; 71.2% males), 414 (34.7%) had a prosthetic valve and 284 (23.8%) had a cardiac implanted electronic device (CIED); 946 (79.2%) were adjudicated as certain IE; 978 (81.9%), 997 (83.5%), and 1057 (88.5%) were classified as definite IE in the 2000 modified Duke, 2015 ESC, and 2023 Duke-ISCVID criteria, respectively. The sensitivity of each set of criteria was 93.2% (95% confidence interval [CI], 91.6-94.8), 95.0% (95% CI, 93.7-96.4), and 97.6% (95% CI, 96.6-98.6), respectively (P < .001 for all 2-by-2 comparisons). Corresponding specificity rates were 61.3% (95% CI, 55.2-67.4), 60.5% (95% CI, 54.4-66.6), and 46.0% (95% CI, 39.8-52.2), respectively. In patients without CIED, sensitivity rates were 94.8% (95% CI, 93.2-96.4), 96.5% (95% CI, 95.1-97.8), and 97.7% (95% CI, 96.6-98.8); specificity rates were 59.0% (95% CI, 51.6-66.3), 56.6% (95% CI, 49.3-64.0), and 53.8% (95% CI, 46.3-61.2), respectively. CONCLUSIONS: Overall, the 2023 Duke-ISCVID criteria had a significantly higher sensitivity but a significantly lower specificity compared with older criteria. This decreased specificity was mainly attributable to patients with CIED.

OBJECTIVE: To determine the background, bacteriological, clinical and radiological findings, associated lesions, treatment and outcome of splenic abscesses (SAs) in infective endocarditis (IE). METHODS: Retrospective study (2005-2021) of 474 patients with definite IE. The diagnosis of SA was made in 36 (7.6%) patients (31, 86.1%, males, mean age = 51.3) on abdominal CT. RESULTS: The main implicated organisms were Streptococcus spp (36.1%), Enterococcus faecalis (27.7%), Staphyloccus spp (19.4%). Rare agents were present in 10 patients (27.8%). Pre-existing conditions included a prosthetic valve (19.4%), previous IE (13.9%), intravenous drug use (8.4%), diabetes (25%) alcohol abuse (13.9%), liver disease (5.5%). Vegetations ≥ 15 mm were present in 36.1%. Common presentations were abdominal pain (19.4%) and left-sided pleural effusion (16.5%). SA were more often small (50%; 7 multiple) than large (36.1%; 1 multiple) or microabscesses (13.9%, 3 multiple). Associated complications were extrasplenic abscesses (brain, 11.1%; lung, 5.5%; liver, 2.8%), infectious aneurysms (16.7%: 3 intracranial, 1 splenic, 1 hepatic, 1 popliteal), emboli (brain, 52.8%; spleen, 44.4%, 5 evolving to SA; kidney, 22.2%; aorta, 2.8%), osteoarticular infections (25%). Twenty-eight (77.8%) patients only received antimicrobials, 7 (19.4%) underwent splenectomy, after cardiac surgery in 5. One had percutaneous drainage. The outcome was uneventful (follow-up 3 months-14 years; mean: 17.2 months). CONCLUSION: In SA-IE patients, the prevalence of vegetation size, Enterococcus faecalis, rare germs, diabetes, osteo-arthritic involvement and cancer was higher than in non-SA patients. Some SAs developed from splenic infarcts. IE-patients with evidence of splenic emboli should be evaluated for a possible abcedation. Cardiac surgery before splenectomy was safe.
ABSTRACT
BACKGROUND: Hepatic artery aneurysms (HAAs), albeit rare in infective endocarditis (IE), are associated with a life-threatening morbidity. METHODS: Retrospective review of 10 HAA-IE patients based on a total of 623 IE patients managed in 2 institutions (2008-2020) versus 35 literature cases. RESULTS: In our patient population, HAAs (10 males, mean age 48) were incidentally found during IE workup. All were asymptomatic. IE involved mitral (n = 6), aortic (n = 3), or mitral-aortic valve (n = 1). Predisposing factors for IE were as follows: prosthetic valve (n = 6), previous IE (n = 2), IV drug user (n = 1). Streptococcus species (spp.) were predominant (n = 4), then staphylococcus spp (n = 2) and E. faecalis (n = 2). All patients presented associated lesions: infectious aneurysms (n = 5), emboli (n = 9), abscesses (n = 5), and spondylitis/spondylodiscitis (n = 2). HAA patterns on abdominal CT angiography (CTA) were solitary (70%), mean diameter 11.7 mm (range 2-30), intrahepatic location (100%) involving the right HA in 9 out of 10 (90%) patients. In 2 patients, HAAs were complicated (rectorragia and hemobilia in 1, cholestasis in the other). Six patients underwent endovascular hepatic embolization (2 with multiple HAAs). Three HAA-IEs <15 mm resolved under antibiotherapy on abdominal CTA follow-up. All patients underwent cardiac surgery. Late outcome was favorable in all followed patients (5/10). Literature review showed the preponderance of Streptococcus spp., of right lobe and intrahepatic HAA localization. Complications revealed HAAs in patients under antibiotic therapy and/or after cardiac surgery in 17 literature cases of delayed diagnosis. CONCLUSIONS: Abdominal CTA was pivotal in the initial IE workup. Small aneurysms (≤15 mm) resolved under antibiotherapy. The usual treatment modality was HAA embolization and endovascular embolization before valve surgery was safe.

The characterization of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral kinetics in hospitalized patients and its association with mortality is unknown. We analyzed death and nasopharyngeal viral kinetics in 655 hospitalized patients from the prospective French COVID cohort. The model predicted a median peak viral load that coincided with symptom onset. Patients with age ≥65 y had a smaller loss rate of infected cells, leading to a delayed median time to viral clearance occurring 16 d after symptom onset as compared to 13 d in younger patients (P < 10-4). In multivariate analysis, the risk factors associated with mortality were age ≥65 y, male gender, and presence of chronic pulmonary disease (hazard ratio [HR] > 2.0). Using a joint model, viral dynamics after hospital admission was an independent predictor of mortality (HR = 1.31, P < 10-3). Finally, we used our model to simulate the effects of effective pharmacological interventions on time to viral clearance and mortality. A treatment able to reduce viral production by 90% upon hospital admission would shorten the time to viral clearance by 2.0 and 2.9 d in patients of age <65 y and ≥65 y, respectively. Assuming that the association between viral dynamics and mortality would remain similar to that observed in our population, this could translate into a reduction of mortality from 19 to 14% in patients of age ≥65 y with risk factors. Our results show that viral dynamics is associated with mortality in hospitalized patients. Strategies aiming to reduce viral load could have an effect on mortality rate in this population.

The microbiology, epidemiology, diagnostics, and treatment of infective endocarditis (IE) have changed significantly since the Duke Criteria were published in 1994 and modified in 2000. The International Society for Cardiovascular Infectious Diseases (ISCVID) convened a multidisciplinary Working Group to update the diagnostic criteria for IE. The resulting 2023 Duke-ISCVID IE Criteria propose significant changes, including new microbiology diagnostics (enzyme immunoassay for Bartonella species, polymerase chain reaction, amplicon/metagenomic sequencing, in situ hybridization), imaging (positron emission computed tomography with 18F-fluorodeoxyglucose, cardiac computed tomography), and inclusion of intraoperative inspection as a new Major Clinical Criterion. The list of "typical" microorganisms causing IE was expanded and includes pathogens to be considered as typical only in the presence of intracardiac prostheses. The requirements for timing and separate venipunctures for blood cultures were removed. Last, additional predisposing conditions (transcatheter valve implants, endovascular cardiac implantable electronic devices, prior IE) were clarified. These diagnostic criteria should be updated periodically by making the Duke-ISCVID Criteria available online as a "Living Document."

BACKGROUND: Although bacterial infections are frequent during pregnancy, the prescription of antibiotics to pregnant women represents a challenge for physicians, driven by the benefit-risk balance. OBJECTIVES: To assess the extent of prenatal antibiotic exposure and its associated factors. METHODS: This study included pregnancies in the National Mother-Child EPI-MERES Register 2010-19 (built from the French Healthcare Data System) regardless of outcome. Antibiotic exposure was defined as having at least one antibiotic prescription filled during pregnancy. The prevalence of pregnancies exposed to antibiotics was estimated. Univariable Poisson regression with generalized estimating equations was used to compare the number of antibiotic prescriptions filled during pregnancy and the period after pregnancy with the period 1 year before pregnancy. Multivariable Poisson regression was used to investigate factors associated with antibiotic exposure during pregnancy. RESULTS: Among 9â769â764 pregnancies, 3â501â294 (35.8%) were exposed to antibiotics and amoxicillin was the most common. Compared with a similar period 1 year before pregnancy, the number of filled antibiotic prescriptions was lower during pregnancy [incidence rate ratio (IRR) 0.903 (95% CI 0.902-0.905)] and during the period 1 year after pregnancy [IRR 0.880 (95% CI 0.879-0.881)]. Region of residence, deprivation index, smoking-related conditions and chronic diseases (especially chronic respiratory diseases) were associated with antibiotic exposure during pregnancy. CONCLUSIONS: Antibiotic prescriptions are filled less frequently during pregnancy than during the preceding year. This may be due to a more relevant benefit-risk assessment. Pregnant women living with social deprivation, those with smoking-related conditions and those with chronic diseases are more likely to fill antibiotic prescriptions.

AIMS: To describe the trends in anti-infective use during pregnancy between 2010 and 2019 and determine whether they were prescribed according to drug foetal safety international classification systems. METHODS: We conducted a population-based, nationwide study using the French national health data system including all pregnancies ended between 2010 and 2019. Anti-infective agents were considered according to their pharmacological group and potential harmful risk using the Australian and Swedish classification systems. Prevalence rate was estimated annually and by trimester. Average annual percent change (AAPC) and 95% confidence intervals (CIs) were calculated using Joinpoint regression. RESULTS: Among 7 571 035 pregnancies, 3 027 031 (40.0%) received ≥1 antibacterial. This proportion decreased significantly from 41.5% in 2010 to 36.1% in 2019 (AAPC = -1.7%, [95%CI, -2.5 to -1.0%]). Conversely, use of antiviral agents increased during the 10-year study period for anti-herpes simplex virus agents (AAPC = 4.4%, [3.7-5.2%]), influenza agents (AAPC = 25.4%, [6.2-48.1%]) and for HIV-antiretroviral agents (AAPC = 1.3%, [0.6-2.0%]). Use of influenza vaccine increased from 0.2% in 2010 to 4.2% in 2019 (AAPC = 49.7%, [39.3-60.9%]). Among all pregnancies, 0.9% had been exposed to a potentially harmful anti-infective agent increasing from 0.7% in 2010 to 1.2% in 2019 (AAPC = 6.4%, [4.4-8.5%]). CONCLUSION: Based on >7 million pregnancies identified from French nationwide data, this study showed that antibacterials are frequently prescribed during pregnancy although their use has decreased over the past 10 years. Our results suggest that anti-infective agents are generally prescribed in accordance with recommendations, although with a potential for improvement in influenza vaccination.

BACKGROUND: Little is known on headaches long-term persistence after bacterial meningitis and on their impact on patients' quality of life. METHODS: In an ancillary study of the French national prospective cohort of community-acquired bacterial meningitis in adults (COMBAT) conducted between February 2013 and July 2015, we collected self-reported headaches before, at onset, and 12 months (M12) after meningitis. Determinants of persistent headache (PH) at M12, their association with M12 quality of life (SF 12), depression (Center for Epidemiologic Studies Depression Scale) and neuro-functional disability were analysed. RESULTS: Among the 277 alive patients at M12 87/274 (31.8%), 213/271 (78.6%) and 86/277 (31.0%) reported headaches before, at the onset, and at M12, respectively. In multivariate analysis, female sex (OR: 2.75 [1.54-4.90]; p < 0.001), pre-existing headaches before meningitis (OR: 2.38 [1.32-4.30]; p < 0.01), higher neutrophilic polynuclei percentage in the CSF of the initial lumbar puncture (OR: 1.02 [1.00-1.04]; p < 0.05), and brain abscess during the initial hospitalisation (OR: 8.32 [1.97-35.16]; p < 0.01) were associated with M12 persistent headaches. Neither the responsible microorganism, nor the corticoids use were associated with M12 persistent headaches. M12 neuro-functional disability (altered Glasgow Outcome Scale; p < 0.01), M12 physical handicap (altered modified Rankin score; p < 0.001), M12 depressive symptoms (p < 0.0001), and M12 altered physical (p < 0.05) and mental (p < 0.0001) qualities of life were associated with M12 headaches. CONCLUSION: Persistent headaches are frequent one year after meningitis and are associated with quality of life alteration. CLINICAL TRIAL: NCT01730690.

BACKGROUND: Our objective was to evaluate in patients with prosthetic valve endocarditis (PVE) treated conservatively, the prognostic value of white blood cell (WBC) signal intensity on SPECT and to describe the evolution of the WBC signal under antibiotics. METHODS: Patients with PVE treated conservatively and positive WBC-SPECT imaging were identified retrospectively. Signal intensity was classified as intense if equal to or higher, or mild if lower, than the liver signal. Clinical, biological, imaging and follow-up information were collected from medical files. RESULTS: Among 47 patients, WBC signal was classified as intense in 10 patients and as mild, in 37. The incidence of the primary composite endpoint (death, late cardiac surgery, or relapse) was significantly higher in patients with intense vs. mild signal (90% vs. 11%). Twenty-five patients underwent a second WBC-SPECT imaging during follow-up. The prevalence of WBC signal decreased progressively from 89% between 3 and 6 weeks to 42% between 6 and 9 weeks and 8% more than 9 weeks after initiation of antibiotics. CONCLUSIONS: In patients with PVE treated conservatively, intense WBC signal was associated with poor outcome. WBC-SPECT imaging appears as an interesting tool for risk stratification and to monitor locally the efficacy of antibiotic treatment.

BACKGROUND: Brain abscesses (BA) are severe lesions in the course of infective endocarditis (IE). We compare the bacteriological, clinical data, background, associated lesions, and outcome of IE patients with and without BAs, and assess the MRI characteristics of BAs. METHODS: Retrospective study of 351 consecutive patients with definite IE (2005-2020) and at least one brain MRI. Patients with and without BAs were compared. RESULTS: Twenty patients (5.7%) had BA (80% men; median age: 44.9 ± 11.5). They were younger (p = 0.035) and had a higher rate of predisposing factors (previous IE 20% vs 2.2%, p = 0.03), intravenous drug use [25% vs 2.2%; p < 0.0001]), underlying conditions (HIV infection, 20% vs 2.2%, p < 0.0001; alcohol abuse, 20% vs 2.2% p < 0.0001]; liver disease p = 0.04; hemodialysis, p = 0.001; type 2 diabetes, p = 0.001), bacterial meningitis (p = 0.0029), rare species involvement (35% vs 7%, p < 0.0006) and extra-cerebral abscesses (p = 0.0001) compared to patients without BA. Valve vegetations were larger in Group 1 (p = 0.046). Clinical presentation could suggest the diagnosis of BA in only 7/20 (35%) patients. MR identified 58 BAs (mean/patient 2.9; range 2-12): often multiple (80%), bilateral (55%) and ≤ 10 mm (72%). The presence of BA did not modify cardiac surgery indication and timing. Favorable outcome was observed in 85% of patients. CONCLUSION: Rates of predisposing, underlying conditions, rare IE agents, meningitis and metastatic abscesses are significantly higher in BA-IE patients. As BAs can develop in asymptomatic IE patients, the impact of brain MRI on their management needs thoroughly to be further investigated.

BACKGROUND: Community-acquired bacterial meningitis is a rare but severe central nervous system infection that may be associated with cerebrovascular complications (CVC). Our objective is to assess the prevalence of CVC in patients with community-acquired bacterial meningitis and to determine the first-48 h factors associated with CVC. METHODS: We analyzed data from the prospective multicenter cohort study (COMBAT) including, between February 2013 and July 2015, adults with community-acquired bacterial meningitis. CVC were defined by the presence of clinical or radiological signs (on cerebral CT or MRI) of focal clinical symptom. Factors associated with CVC were identified by multivariate logistic regression. RESULTS: CVC occurred in 128 (25.3%) of the 506 patients in the COMBAT cohort (78 (29.4%) of the 265 pneumococcal meningitis, 17 (15.3%) of the 111 meningococcal meningitis, and 29 (24.8%) of the 117 meningitis caused by other bacteria). The proportion of patients receiving adjunctive dexamethasone was not statistically different between patients with and without CVC (p = 0.84). In the multivariate analysis, advanced age (OR = 1.01 [1.00-1.03], p = 0.03), altered mental status at admission (OR = 2.23 [1.21-4.10], p = 0.01) and seizure during the first 48 h from admission (OR = 1.90 [1.01-3.52], p = 0.04) were independently associated with CVC. CONCLUSIONS: CVC were frequent during community-acquired bacterial meningitis and associated with advanced age, altered mental status and seizures occurring within 48 h from admission but not with adjunctive corticosteroids.

AIM: Fatality of infective endocarditis (IE) is high worldwide, and its diagnosis remains a challenge. The objective of the present study was to compare the clinical characteristics and outcomes of patients with culture-positive (CPIE) vs. culture-negative IE (CNIE). METHODS AND RESULTS: This was an ancillary analysis of the ESC-EORP EURO-ENDO registry. Overall, 3113 patients who were diagnosed with IE during the study period were included in the present study. Of these, 2590 (83.2%) had CPIE, whereas 523 (16.8%) had CNIE. As many as 1488 (48.1%) patients underwent cardiac surgery during the index hospitalization, 1259 (48.8%) with CPIE and 229 (44.5%) with CNIE. The CNIE was a predictor of 1-year mortality [hazard ratio (HR) 1.28, 95% confidence interval (CI) 1.04-1.56], whereas surgery was significantly associated with survival (HR 0.49, 95% CI 0.41-0.58). The 1-year mortality was significantly higher in CNIE than CPIE patients in the medical subgroup, but it was not significantly different in CNIE vs. CPIE patients who underwent surgery. CONCLUSION: The present analysis of the EURO-ENDO registry confirms a higher long-term mortality in patients with CNIE compared with patients with CPIE. This difference was present in patients receiving medical therapy alone and not in those who underwent surgery, with surgery being associated with reduced mortality. Additional efforts are required both to improve the aetiological diagnosis of IE and identify CNIE cases early before progressive disease potentially contraindicates surgery.

PURPOSE: To evaluate the usefulness of T2* and FLAIR sequences in the detection of unruptured infectious intracranial aneurysms (UIIAs) in infective endocarditis (IE) including the relationships between the lesion patterns within subarachnoid spaces and the presence of UIIA. METHODS: Retrospective review of 15 consecutive patients with definite IE undergoing MR imaging (FLAIR, T2*, DWI, CE-MRA, 3D-T1, CE-3DT1 sequences), in whom DSA detected infectious intracranial aneurysms (IIA). Aneurysmal features (diameter, location, morphology on DSA) and signal patterns onT2*, FLAIR and conventional MR sequences at the site of the UIIA, follow-up MRI and IE background, were analyzed. A control-group of 15 IE-patients without IIA at DSA served for comparison. RESULTS: Among 17 UIIAs studied, T2* sequence displayed a susceptibility vessel sign in 15/17 (88.2%), both distal and proximal, which matched with the IIA visualized on DSA. Three patterns of hyposignal areas were identified: (a) signet-ring or target-sign appearance (n = 7), (b) homogeneous, round-, oval- or pear-shaped area (n = 4), and (c) heterogeneous area (n = 4). A FLAIR hyperintensity of the lumen and of the adjacent cortex was present in 6 (35.3%) and 9 (53%) UIIAs, respectively. On T1 (12 UIIAs) a rounded hyposignal (n = 2), within the UIIA lumen matched with the FLAIR hypersignal. Using both T2* and FLAIR had an incremental value with 100% sensitivity and specificity. CONCLUSION: The susceptibility vessel sign is an MR imaging pattern frequently observed at the site of UIIAs in IE-patients. Both T2* and FLAIR may have the potential to depict UIIAs, regardless of their location and shape.

BACKGROUND: Health care workers (HCWs) were on the frontline of the current pandemic. We aimed at identifying determinants of SARS-CoV-2 infection and the effectiveness of personal protection equipment (PPE) worn by HCWs before vaccination. METHODS: We abstracted data on SARS-CoV-2 infection based on positive PCR results and sociodemographic characteristics of 38,793 HCWs from public hospitals and public health authorities from 10 European centers. We fitted cohort-specific multivariate logistic regression models to identify determinants of infection and combined the results using random-effects meta-analyses. RESULTS: The overall prevalence of infection before vaccination among HCWs was 9.58%. Infection was associated with the presence of selected symptoms; no association was found between sociodemographic factors and increased risk of infection. The use of PPE and particularly FFP2/FFP3 masks had a different protective effect during the first and second waves of the COVID pandemic. CONCLUSIONS: The study provides evidence that mask use was the most effective PPE in preventing SARS-CoV-2 infection among HCWs.

OBJECTIVES: The purpose of this study was to describe the clinical characteristics and in-hospital and post-discharge outcomes of respiratory syncytial virus (RSV) infection among adults hospitalised with influenza-like illness (ILI) and compared against patients admitted for influenza. METHODS: Adults hospitalised with ILI were prospectively included from five French university hospitals over two consecutive winter seasons (2017/2018 and 2018/2019). RSV and influenza virus were detected by multiplex reverse transcription PCR on nasopharyngeal swabs. RSV-positive patients were compared to RSV-negative and influenza-positive hospitalised patients. Poisson regression models were used to estimate the adjusted prevalence ratio (aPR) associated with in-hospital and post-discharge outcomes between RSV and influenza infections. The in-hospital outcome was a composite of the occurrence of at least one complication, length of stay ≥7â days, intensive care unit admission, use of mechanical ventilation and in-hospital death. Post-discharge outcome included 30- and 90-day all-cause mortality and 90-day readmission rates. RESULTS: Overall, 1428 hospitalised adults with ILI were included. RSV was detected in 8% (114 of 1428) and influenza virus in 31% (437 of 1428). Patients hospitalised with RSV were older than those with influenza (mean age 73.0 versus 68.8â years, p=0.015) with a higher frequency of chronic respiratory or cardiac disease (52% versus 39%, p=0.012, and 52% versus 41%, p=0.039, respectively) and longer hospitalisation duration (median stay 8 versus 6â days, p<0.001). Anti-influenza therapies were less prescribed among RSV patients than influenza patients (20% versus 66%, p<0.001). In-hospital composite outcome was poorer in RSV patients (aPR 1.5, 95% CI 1.1-2.1) than in those hospitalised with influenza. No difference was observed for the post-discharge composite outcome (aPR 1.1, 95% CI 0.8-1.6). CONCLUSION: RSV infection results in serious respiratory illness, with worse in-hospital outcomes than influenza and with similar midterm post-discharge outcomes.

OBJECTIVES: To describe the clinical features and outcomes of infective endocarditis (IE) in pregnant women who do not inject drugs. METHODS: A multinational retrospective study was performed at 14 hospitals. All definite IE episodes between January 2000 and April 2021 were included. The main outcomes were maternal mortality and pregnancy-related complications. RESULTS: Twenty-five episodes of IE were included. Median age at IE diagnosis was 33.2â years (IQR 28.3-36.6) and median gestational age was 30â weeks (IQR 16-32). Thirteen (52%) patients had no previously known heart disease. Sixteen (64%) were native IE, 7 (28%) prosthetic and 2 (8%) cardiac implantable electronic device IE. The most common aetiologies were streptococci (nâ=â10, 40%), staphylococci (nâ=â5, 20%), HACEK group (nâ=â3, 12%) and Enterococcus faecalis (nâ=â3, 12%). Twenty (80%) patients presented at least one IE complication; the most common were heart failure (nâ=â13, 52%) and symptomatic embolism other than stroke (nâ=â4, 16%). Twenty-one (84%) patients had surgery indication and surgery was performed when indicated in 19 (90%). There was one maternal death and 16 (64%) patients presented pregnancy-related complications (11 patients ≥1 complication): 3 pregnancy losses, 9 urgent Caesarean sections, 2 emergency Caesarean sections, 1 fetal death, and 11 preterm births. Two patients presented a relapse during a median follow-up of 3.1â years (IQR 0.6-7.4). CONCLUSIONS: Strict medical surveillance of pregnant women with IE is required and must involve a multidisciplinary team including obstetricians and neonatologists. Furthermore, the potential risk of IE during pregnancy should never be underestimated in women with previously known underlying heart disease.

PURPOSE: Invasive pneumococcal disease (IPD) is responsible for substantial mortality and morbidity worldwide. We aimed to identify host and bacterial factors associated with 30-day mortality in 18-year-old patients hospitalized with IPD in France from 2013 to 2015. METHODS: This study analyzed data collected from consecutives IPD cases included in two parallel multi-center cohort studies: COMBAT study (280 patients with pneumococcal community-acquired bacterial meningitis) and SIIP study (491 patients with non-meningitis IPD). Factors associated with 30-day mortality were identified using logistic regression. RESULTS: Among the 771 enrolled patients (median age 66 years, IQR [52.0-79.7]), 592/767 (77.2%) had at least one chronic disease. Patients with meningitis were younger (60.2 vs 70.9 years; p < 0.001) and had fewer chronic diseases than those with non-meningitis IPD (73.3% vs 79.4%; p = 0.05). Non-vaccine serotypes were more frequent in meningitis patients than in those with other IPD (36.1% vs 23.1%; p < 0.001). The overall 30-day mortality was 16.7% and patients with concurrent meningitis and extra-cerebral IPD had the highest 30-day mortality rate (26.5%). On multivariate analyses, older age, history of malignant solid tumor, meningeal IPD and serotypes previously identified with high mortality potential were independently associated with 30-day mortality. Of the serotypes with high mortality potential, 80% were included in licensed (PCV13 or PPV23) vaccines. CONCLUSION: We observed an effect of both host factors and pneumococcal serotypes on 30-day mortality in IPD. This highlights the need for a focused strategy to vaccinate at-risk patients. CLINICAL TRIAL: ClinicalTrial. Gov identification number: NCT01730690.

PURPOSE: To investigate the prevalence of neuro-functional disability and its determinants 12 months after community-acquired bacterial meningitis (CABM) in adult patients. METHODS: In a prospective multicenter cohort study (COMBAT), all consecutive cases of CABM were enrolled and followed up for 12 months. Neuro-functional disability at 12 months was evaluated using a combination of the Glasgow Outcome Scale (functional disability), and the modified Rankin Disability Scale (physical disability). Factors associated with neuro-functional disability were identified by multivariate logistic regression. RESULTS: Among 281 patients, 84 (29.9%) patients exhibited neuro-functional disability at 12 months: 79 (28.1%) with functional disability and 51 (18.1%) with physical disability. Overall, 6 patients (2.1%) died during the follow-up. The most common pathogen identified was Streptococcus pneumoniae (131/272, 48.2%); 77/268 patients (28.7%) had a physical disability at hospital discharge. Factors independently associated with 12-month neuro-functional disability were a pneumococcal meningitis (adjusted OR = 2.8; 95% confidence interval (CI) = [1.3; 6.7]), the presence of a physical disability at hospital discharge (aOR = 2.3; 95%CI = [1.2; 4.4]) and the presence of behavioral disorders at hospital-discharge (aOR = 5.9; 95%CI = [1.6; 28.4]). Dexamethasone use was not significantly associated with neuro-functional disability (OR = 0.2; 95%CI = [< 0.1;1.3]). CONCLUSION: Neuro-functional disability is frequently reported 12 months after CABM. Detailed neurological examination at discharge is needed to improve the follow-up. TRIAL REGISTRATION: NCT01730690.

INTRODUCTION: Characterizing immunological response following COVID-19 vaccination is an important public health issue. The objectives of the present analysis were to investigate the proportion, level and the determinants of humoral response from 21 days to three months after the first dose in vaccinated healthcare workers (HCWs). METHODS: We abstracted data on level of anti-SARS-CoV-2 Spike antibodies (IgG) and sociodemographic characteristics of 17,257 HCWs from public hospitals and public health authorities from three centers in Northern Italy who underwent COVID-19 vaccination (average 70.6 days after first dose). We fitted center-specific multivariate regression models and combined them using random-effects meta-analyses. RESULTS: A humoral response was elicited in 99.3% of vaccinated HCW. Female sex, young age, and previous COVID-19 infection were predictors of post-vaccination antibody level, and a positive association was also detected with pre-vaccination serology level and with time between pre- and post-vaccination testing, while a decline of antibody level was suggested with time since vaccination. CONCLUSIONS: These results stress the importance of analyzing retrospective data collected via occupational health surveillance of HCWs during the COVID-19 epidemic and following vaccination. They need to be confirmed in larger series based on prospectively collected data.
