RESUMO

BACKGROUND: Group A Streptococcus is responsible for severe and potentially lethal invasive conditions requiring intensive care unit (ICU) admission, such as streptococcal toxic shock-like syndrome (STSS). A rebound of invasive group A streptococcal (iGAS) infection after COVID-19-associated barrier measures has been observed in children. Several intensivists of French adult ICUs have reported similar bedside impressions without objective data. We aimed to compare the incidence of iGAS infection before and after the COVID-19 pandemic, describe iGAS patients' characteristics, and determine ICU mortality associated factors. METHODS: We performed a retrospective multicenter cohort study in 37 French ICUs, including all patients admitted for iGAS infections for two periods: two years before period (October 2018 to March 2019 and October 2019 to March 2020) and a one-year after period (October 2022 to March 2023) COVID-19 pandemic. iGAS infection was defined by Group A Streptococcus isolation from a normally sterile site. iGAS infections were identified using the International Classification of Diseases and confirmed with each center's microbiology laboratory databases. The incidence of iGAS infections was expressed in case rate. RESULTS: Two hundred and twenty-two patients were admitted to ICU for iGAS infections: 73 before and 149 after COVID-19 pandemic. Their case rate during the period before and after COVID-19 pandemic was 205 and 949/100,000 ICU admissions, respectively (p < 0.001), with more frequent STSS after the COVID-19 pandemic (61% vs. 45%, p = 0.015). iGAS patients (n = 222) had a median SOFA score of 8 (5-13), invasive mechanical ventilation and norepinephrine in 61% and 74% of patients. ICU mortality in iGAS patients was 19% (14% before and 22% after COVID-19 pandemic; p = 0.135). In multivariate analysis, invasive mechanical ventilation (OR = 6.08 (1.71-21.60), p = 0.005), STSS (OR = 5.75 (1.71-19.22), p = 0.005), acute kidney injury (OR = 4.85 (1.05-22.42), p = 0.043), immunosuppression (OR = 4.02 (1.03-15.59), p = 0.044), and diabetes (OR = 3.92 (1.42-10.79), p = 0.008) were significantly associated with ICU mortality. CONCLUSION: The incidence of iGAS infections requiring ICU admission increased by 4 to 5 after the COVID-19 pandemic. After the COVID-19 pandemic, the rate of STSS was higher, with no significant increase in ICU mortality rate.

RESUMO

Background: Legionnaires' disease (LD) is an important cause of community-acquired pneumonia with high mortality rates in the most severe cases. Objectives: To evaluate the effect of antimicrobial strategy on ICU mortality. Methods: Retrospective, observational study including patients admitted to 10 ICUs for severe community-acquired LD over a 10 year period (2005-15) and receiving an active therapy within 48 h of admission . Patients were stratified according to the antibiotic strategy administered: (i) fluoroquinolone-based versus non-fluoroquinolone-based therapy; and (ii) monotherapy versus combination therapy. The primary endpoint was in-ICU mortality. A multivariable Cox model and propensity score analyses were used. Results: Two hundred and eleven patients with severe LD were included. A fluoroquinolone-based and a combination therapy were administered to 159 (75%) and 123 (58%) patients, respectively. One hundred and forty-six patients (69%) developed acute respiratory distress syndrome and 54 (26%) died in the ICU. In-ICU mortality was lower in the fluoroquinolone-based than in the non-fluoroquinolone-based group (21% versus 39%, P = 0.01), and in the combination therapy than in the monotherapy group (20% versus 34%, P = 0.02). In multivariable analysis, a fluoroquinolone-based therapy, but not a combination therapy, was associated with a reduced risk of mortality [HR = 0.41, 95% CI 0.19-0.89; P = 0.02]. Conclusions: Patients with severe LD receiving a fluoroquinolone-based antimicrobial regimen in the early course of management had a lower in-ICU mortality, which persisted after adjusting for significant covariates.

RESUMO

PURPOSE: We aimed to characterize the outcomes of patients with severe meningoencephalitis requiring intensive care. METHODS: We conducted a prospective multicenter international cohort study (2017-2020) in 68 centers across 7 countries. Eligible patients were adults admitted to the intensive care unit (ICU) with meningoencephalitis, defined by an acute onset of encephalopathy (Glasgow coma scale (GCS) score [Formula: see text] 13), a cerebrospinal fluid pleocytosis [Formula: see text] 5 cells/mm3, and at least two of the following criteria: fever, seizures, focal neurological deficit, abnormal neuroimaging, and/or electroencephalogram. The primary endpoint was poor functional outcome at 3 months, defined by a score of three to six on the modified Rankin scale. Multivariable analyses stratified on centers investigated ICU admission variables associated with the primary endpoint. RESULTS: Among 599 patients enrolled, 589 (98.3%) completed the 3-month follow-up and were included. Overall, 591 etiologies were identified in those patients which were categorized into five groups: acute bacterial meningitis (n = 247, 41.9%); infectious encephalitis of viral, subacute bacterial, or fungal/parasitic origin (n = 140, 23.7%); autoimmune encephalitis (n = 38, 6.4%); neoplastic/toxic encephalitis (n = 11, 1.9%); and encephalitis of unknown origin (n = 155, 26.2%). Overall, 298 patients (50.5%, 95% CI 46.6-54.6%) had a poor functional outcome, including 152 deaths (25.8%). Variables independently associated with a poor functional outcome were age > 60 years (OR 1.75, 95% CI 1.22-2.51), immunodepression (OR 1.98, 95% CI 1.27-3.08), time between hospital and ICU admission > 1 day (OR 2.02, 95% CI 1.44-2.99), a motor component on the GCS [Formula: see text] 3 (OR 2.23, 95% CI 1.49-3.45), hemiparesis/hemiplegia (OR 2.48, 95% CI 1.47-4.18), respiratory failure (OR 1.76, 95% CI 1.05-2.94), and cardiovascular failure (OR 1.72, 95% CI 1.07-2.75). In contrast, administration of a third-generation cephalosporin (OR 0.54, 95% CI 0.37-0.78) and acyclovir (OR 0.55, 95% CI 0.38-0.80) on ICU admission were protective. CONCLUSION: Meningoencephalitis is a severe neurologic syndrome associated with high mortality and disability rates at 3 months. Actionable factors for which improvement could be made include time from hospital to ICU admission, early antimicrobial therapy, and detection of respiratory and cardiovascular complications at admission.

RESUMO

INTRODUCTION: A palliative approach to intensive care unit (ICU) patients with acute respiratory failure and a do-not-intubate order corresponds to a poorly evaluated target for non-invasive oxygenation treatments. Survival alone should not be the only target; it also matters to avoid discomfort and to restore the patient's quality of life. We aim to conduct a prospective multicentre observational study to analyse clinical practices and their impact on outcomes of palliative high-flow nasal oxygen therapy (HFOT) and non-invasive ventilation (NIV) in ICU patients with do-not-intubate orders. METHODS AND ANALYSIS: This is an investigator-initiated, multicentre prospective observational cohort study comparing the three following strategies of oxygenation: HFOT alone, NIV alternating with HFOT and NIV alternating with standard oxygen in patients admitted in the ICU for acute respiratory failure with a do-not-intubate order. The primary outcome is the hospital survival within 14 days after ICU admission in patients weaned from NIV and HFOT. The sample size was estimated at a minimum of 330 patients divided into three groups according to the oxygenation strategy applied. The analysis takes into account confounding factors by modelling a propensity score. ETHICS AND DISSEMINATION: The study has been approved by the ethics committee and patients will be included after informed consent. The results will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03673631.

RESUMO

INTRODUCTION: Clostridium tertium septicaemia, although usually described in neutropenic patients, can also occur in the absence of neutropenia, as in our case report. OBSERVATION: A 61 year-old woman presented with pain in the right hypochondrium and epigastrium, constipation and vomiting that led to the diagnosis of acute pancreatitis of biliary origin. During septic shock, analysis of the liquid of an intra-abdominal mass and the results of the blood cultures revealed a Gram positive bacillus identified as C. tertium. During laparotomy, necrotic-hemorrhagic acute pancreatitis lesions were found with subtotal colic necrosis. Analysis of the peritoneal fluid revealed C. tertium. The patient died on D 46 after several nosocomial pneumopathies without identification of C. tertium. DISCUSSION: Three factors appear related to the onset of C. tertium septicaemia: neutropenia, lesions of the intestinal mucosa and previous treatment with 3rd generation, broad spectrum, cephalosporins. Such septicaemias are rare in immunocompetent patients and do not appear to have been reported before in a context of acute pancreatitis.

RESUMO

INTERESTS AND OBJECTIVES: Patients' general practitioners (GPs) could be relevant consultants for collegial decisions of withholding or withdrawing treatment (WWT) defined by the Leonetti law. We therefore studied their implication by intensivists in end-of-life decisions and collected their feelings. Their wishes for the coming law revision were also investigated. METHODS: Retrospective descriptive study conducted in the polyvalent intensive care unit (ICU) of Longjumeau's hospital (France) using a distributed questionnaire to GPs of patients who benefited from collegial decisions of WWT in 2012. RESULTS: The response rate was 60.4% (32/53) and only 18.8% of the respondents participated as a consultant in WWT's decision for their patient. Two GPs out of three reported that they never participate in such decisions for their others patients. All uninvolved GPs did not contribute because intensivists did not consult them. Only 43.7% of GPs were contacted by intensivists during the stay and 21.9% at the discharge or death of their patient. GPs took news about their patient during ICU hospitalization in 37.5% of cases. Regarding uninvolved GPs, their participation could have changed WWT's decisions made for two patients (7.7%). Most respondents felt available (78.1%) and skilled (81.2 %) to participate in this kind of decision. A third was also questioned by the patient's family about it. Only 21.7% of GPs report to be familiar with the French end-of-life legislation. In case of a next revision, two thirds considered important to make the use of GPs obligatory in such decisions. CONCLUSION: Despite an undeniable interest, GPs are rarely involved in collegial processes of WWT in ICUs, partially related to an insufficient knowledge of the law by the healthcare providers. At the dawn of end-of-life law's revision, their share could however improve our practices in this field.
