RESUMEN
Background: Human metapneumovirus (hMPV) is one of the leading respiratory viruses. This prospective observational study aimed to describe the clinical features and the outcomes of hMPV-associated lower respiratory tract infections in adult inpatients. Methods: Consecutive adult patients admitted to one of the 31 participating centers with an acute lower respiratory tract infection and a respiratory multiplex PCR positive for hMPV were included. A primary composite end point of complicated course (hospital death and/or the need for invasive mechanical ventilation) was used. Results: Between March 2018 and May 2019, 208 patients were included. The median age was 74 [62-84] years. Ninety-seven (47 %) patients were men, 187 (90 %) had at least one coexisting illness, and 67 (31 %) were immunocompromised. Median time between first symptoms and hospital admission was 3 [2-7] days. The two most frequent symptoms were dyspnea (86 %) and cough (85 %). The three most frequent clinical diagnoses were pneumonia (42 %), acute bronchitis (20 %) and acute exacerbation of chronic obstructive pulmonary disease (16 %). Among the 52 (25 %) patients who had a lung CT-scan, the most frequent abnormality was ground glass opacity (41 %). While over four-fifths of patients (81 %) received empirical antibiotic therapy, a bacterial coinfection was diagnosed in 61 (29 %) patients. Mixed flora (16 %) and enterobacteria (5 %) were the predominant documentations. The composite criterion of complicated course was assessable in 202 (97 %) patients, and present in 37 (18 %) of them. In the subpopulation of pneumonia patients (42 %), we observed a more complicated course in those with a bacterial coinfection (8/24, 33 %) as compared to those without (5/60, 8 %) (p = 0.02). Sixty (29 %) patients were admitted to the intensive care unit. Among them, 23 (38 %) patients required invasive mechanical ventilation. In multivariable analysis, tachycardia and alteration of consciousness were identified as risk factors for complicated course. Conclusion: hMPV-associated lower respiratory tract infections in adult inpatients mostly involved elderly people with pre-existing conditions. Bacterial coinfection was present in nearly 30 % of the patients. The need for mechanical ventilation and/or the hospital death were observed in almost 20 % of the patients.
RESUMEN
Background: Despite advances in asthma treatments, severe asthma exacerbation (SAE) remains a life-threatening condition in adults, and there is a lack of data derived from adult patients admitted to intensive care units (ICUs) for SAE. The current study investigated changes in adult patient characteristics, management, and outcomes of SAE over a 20-year period in 40 ICUs in the greater Paris area. Methods: In this retrospective observational study, admissions to 40 ICUs in the greater Paris area for SAE from January 1, 1997, to December 31, 2016 were analyzed. The primary outcome was the proportion of ICU admissions for SAE during 5-year periods. Secondary outcomes were ICU and hospital mortality, and the use of mechanical ventilation and catecholamine. Multivariate analysis was performed to assess factors associated with ICU mortality. Results: A total of 7049 admissions for SAE were recorded. For each 5-year period, the proportion decreased over time, with SAE accounting for 2.84% of total ICU admissions (n=2841) between 1997 and 2001, 1.76% (n=1717) between 2002 and 2006, 1.05% (n=965) between 2007 and 2011, and 1.05% (n=1526) between 2012 and 2016. The median age was 46 years (interquartile range [IQR]: 32-59 years), 55.41% were female, the median Simplified Acute Physiology Score II was 20 (IQR: 13-28), and 19.76% had mechanical ventilation. The use of mechanical ventilation remained infrequent throughout the 20-year period, whereas the use of catecholamine decreased. ICU and hospital mortality rates decreased. Factors associated with ICU mortality were renal replacement therapy, catecholamine, cardiac arrest, pneumothorax, acute respiratory distress syndrome, sepsis, and invasive mechanical ventilation (IMV). Non-survivors were older, had more severe symptoms, and were more likely to have received IMV. Conclusion: ICU admission for SAE remains uncommon, and the proportion of cases decreased over time. Despite a slight increase in symptom severity during a 20-year period, ICU and hospital mortality decreased. Patients requiring IMV had a higher mortality rate.
RESUMEN
BACKGROUND: Alongside the recent worldwide expansion of hypervirulent Klebsiella pneumoniae (KP) infections, the available literature regarding cases of community acquired pneumonias (KP-CAP) remains scarce but reports a strikingly high and early mortality. We performed a retrospective multicenter study (7 ICU in France) between 2015 and 2019, comparing prognosis and severity of KP-CAP versus Streptococcus pneumoniae - CAP (SP-CAP). METHODS: For each KP-CAP, three SP-CAP admitted in ICUs within the same center and within the same 6-month window were selected. When available, KP strains were studied, and bacterial virulence was genetically assessed for virulence factors. The primary outcome was in-hospital mortality. Associations between clinical outcomes and type of infection were tested using univariate and multivariate logistic regressions, adjusted for pairing variables. RESULTS: Twenty-seven KP-CAP and 81 SP-CAP were included. Respective in-hospital mortality rates were 59% (n = 16) and 17% (n = 14, p < 0.001), despite adequate antibiotic therapy. KP-CAP median time from admission to death was 26.9 h [IQR 5.75-44 h] and were significantly associated with higher rates of multiple organ failures (93% vs. 42%, p < 0.001), disseminated intravascular coagulation (12% vs. 1.3%, p = 0.046), septic shock (median lactate on ICU admission 4.60 vs. 2.90 mmol/L, p = 0.030) and kidney failure (KDIGO-3: 87% vs. 44%, p < 0.001). Interestingly, alcoholism was the only identified predisposing factor of KP-CAP. Severity on ICU admission (2-fold higher for KP-CAP) was the only factor associated with mortality in a multivariate analysis. CONCLUSION: We described a strong association between KP-CAP infection and higher and earlier mortality when compared to SP-CAP. Moreover, alcoholism was the sole predisposing factor associated with KP-CAP infection. These findings should raise awareness of clinicians involved in the management of severe CAP about this microbiological etiology. Future prospective studies are needed to confirm these results and to design strategies to improve the prognosis of such infections.
RESUMEN
OBJECTIVES: The occurrence of mediastinitis after cardiac surgery remains a rare and severe complication associated with poor outcomes. Whereas bacterial mediastinitis have been largely described, little is known about their fungal etiologies. We report incidence, characteristics and outcome of post-cardiac surgery fungal mediastinitis. METHODS: Multicenter retrospective study among 10 intensive care units (ICU) in France and Belgium of proven cases of fungal mediastinitis after cardiac surgery (2009-2019). RESULTS: Among 73,688 cardiac surgery procedures, 40 patients developed fungal mediastinitis. Five were supported with left ventricular assist device and five with veno-arterial extracorporeal membrane oxygenation before initial surgery. Twelve patients received prior heart transplantation. Interval between initial surgery and mediastinitis was 38 [17-61] days. Only half of the patients showed local signs of infection. Septic shock was uncommon at diagnosis (12.5%). Forty-three fungal strains were identified: Candida spp. (34 patients), Trichosporon spp. (5 patients) and Aspergillus spp. (4 patients). Hospital mortality was 58%. Survivors were younger (59 [43-65] vs. 65 [61-73] yo; p = 0.013), had lower body mass index (24 [20-26] vs. 30 [24-32] kg/m2; p = 0.028) and lower Simplified Acute Physiology Score II score at ICU admission (37 [28-40] vs. 54 [34-61]; p = 0.012). CONCLUSION: Fungal mediastinitis is a very rare complication after cardiac surgery, associated with a high mortality rate. This entity should be suspected in patients with a smoldering infectious postoperative course, especially those supported with short- or long-term invasive cardiac support devices, or following heart transplantation.

BACKGROUND: A bedside screening tool of swallowing dysfunction (SD) (BSSD) after extubation would be useful to identify patients who are at risk of SD. We aimed to evaluate the accuracy of our BSSD in comparison with fiberoptic endoscopic evaluation of swallowing (FEES) in critically ill patients after extubation. METHODS: We conducted a 1-year prospective monocentric study to evaluate the accuracy of our BSSD to diagnose SD following endotracheal intubation in comparison with FEES (gold standard). Patients intubated for longer than 48 h were included. Both tests were assessed within 24 h after extubation. Primary endpoint was the accuracy of the BSSD. Secondary endpoint was to assess risk factors of SD. RESULTS: Seventy-nine patients were included in the study. Thirty-three patients (42%) presented with a SD. The BSSD showed a sensitivity of 88% (95% CI 0.72-0.97) and a specificity of 91% (95% CI 0.79-0.98), a positive predictive value of 88% (95% CI 0.72-0.97) and a negative predictive value of 91% (95% CI 0.79-0.97). The AUC reached 0.83 (95% CI 0.74-0.92). CONCLUSION: Our study describes an accurate clinical screening tool to detect SD after extubation in critically ill patients. Screening-positive cases should be confirmed by instrumental tests, ideally using FEES.

BACKGROUND: In-hospital cardiac arrest(IHCA) has received little attention compared with out-of-hospital cardiac arrest. AIM: To address the paucity of data on IHCA patients, we examined key features, variations in mortality and predictors of death among patients admitted in French intensive care units(ICUs) from 1997 to 2015. METHODS: Using the database of the Collège des Utilisateurs de Bases de données en Réanimation(CUB-Réa) that prospectively collects data from ICUs in the greater Paris area, we determined temporal trends in the incidence of IHCA, patients' outcomes, crude and Simplified Acute Physiology Score(SAPS)-II Standardized mortality and predictors of in-ICU mortality. RESULTS: Of the 376,325 ICU admissions, 15,324(4.08%) had IHCA, with incidence increasing from 2.78% to 3.83%(p < 0.001). Over time, the patient age increased by 0.7 years(p = 0.04) and SAPS-II increased by 2.3%(p < 0.001). Crude in-ICU mortality decreased from 78% to 62.5% over the past 18 years(p < 0.001). The SAPS-II-standardized mortality also decreased over time from 78.4% to 68.3%(p < 0.001) representing a 10.1% relative decrease from 1997 to 2015. In multivariate analysis, admission in a more recent time-period was an independent correlate of decreased mortality(OR 0.40, 95%CI 0.35-0.46). CONCLUSION: Occurrence of IHCA increased over time but remains an uncommon reason for being admitted to ICU. From 1997 to 2015, we observed a change in patient profile, with older and more critically ill patients, despite which in-ICU mortality has substantially decreased in IHCA patients, likely resulting from a global improvement in the process of care and more widespread implementation of rapid response teams.

BACKGROUND: Studies describing the clinical features and short-term prognosis of patients admitted to the intensive care unit (ICU) for menstrual toxic shock syndrome (m-TSS) are lacking. METHODS: This was a multicenter retrospective cohort study of patients with a clinical diagnosis of m-TSS admitted between 1 January 2005 and 31 December 2020 in 43 French pediatric (nâ =â 7) or adult (nâ =â 36) ICUs. The aim of the study was to describe the clinical features and short-term prognosis, as well as to assess the 2011 Centers for Disease and Control (CDC) diagnostic criteria, in critically ill patients with m-TSS. RESULTS: In total, 102 patients with m-TSS (median age, 18 years; interquartile range, 16-24 years) were admitted to 1 of the participating ICUs. All blood cultures (nâ =â 102) were sterile. Methicillin-sensitive Staphylococcus aureus grew from 92 of 96 vaginal samples. Screening for superantigenic toxin gene sequences was performed for 76 of the 92 vaginal samples positive for S. aureus (83%), and toxic shock syndrome toxin 1 was isolated from 66 strains (87%). At ICU admission, no patient met the 2011 CDC criteria for confirmed m-TSS, and only 53 (52%) fulfilled the criteria for probable m-TSS. Eighty-one patients (79%) were treated with antitoxin antibiotic therapy, and 8 (8%) received intravenous immunoglobulins. Eighty-six (84%) patients required vasopressors, and 21 (21%) tracheal intubation. No patient required limb amputation or died in the ICU. CONCLUSIONS: In this large multicenter series of patients included in ICUs for m-TSS, none died or required limb amputation. The CDC criteria should not be used for the clinical diagnosis of m-TSS at ICU admission.

BACKGROUND: Long-term outcomes of awakened survivors of out-of-hospital cardiac arrest (OHCA) are poorly known. RESEARCH QUESTION: What are the month (M) 18 outcomes of survivors of out-of-hospital cardiac arrest (OHCA) who awakened during the first 2 weeks' post-OHCA and their poor-outcome risk factors? STUDY DESIGN AND METHODS: All OHCA survivors with a Glasgow Coma Scale score ≥12 during the first 2 weeks' post-OHCA were enrolled in six ICUs and followed up at M3, M6, M12, and M18. The primary outcome measure was Glasgow Outcome Scale-Extended (GOS-E) score at M18. Secondary outcome measures included evaluation at M18 of neurologic, behavioral, and cognitive disabilities; health-related quality of life (HR-QOL), anxiety and depression; and poor-outcome risk factors (GOS-E score ≤ 6). RESULTS: Among the 139 included patients, 98 were assessable for the primary outcome measure. At M18, 64 (65%) had full recovery or minor disabilities (GOS-E score > 6), 18 (18%) had moderate disabilities but were autonomous for daily-life activities (GOS-E score = 6), 12 (12%) had poor autonomy (GOS-E score < 6 but > 1), and four had died. Percentages of patients with GOS-E scores > 6 increased significantly over the 18-month study period. At M18, no patients had major neurologic disabilities, 20% had cognitive disabilities, 32% had anxiety symptoms, 25% had depression symptoms, and their HR-QOL was impaired compared with a sex- and age-matched population. Low-flow time, Sequential Organ Failure Assessment score at admission, coma duration > 3 days after cardiac arrest, and mechanical ventilation on days 3 and 7 were associated with poor functional outcome. INTERPRETATION: Among patients who awoke (Glasgow Coma Scale score ≥12) in the 14 days following OHCA, 35% had moderate to severe disabilities or had died at M18. Interestingly, patients improved until M18 post-OHCA. Risk factors associated with poor functional outcome were low-flow time, clinical severity at ICU admission, prolonged coma duration, and mechanical ventilation.

INTRODUCTION: Prolonged stays in ICU have been associated with overconsumption of resources but little is known about their epidemiology. We aimed to identify predictors and prognostic factors of extended stays, studying a long-stay population. METHODS: We present a retrospective cohort study between July 2000 and December 2013 comparing patients hospitalized in a medical ICU for ≥30 days (long-stay patients-LSP) with patients hospitalized for <30 days (short-stay patients-SSP). Admission characteristics were collected from the local database for every patient and evolution during the ICU stay was retrieved from LSP files. RESULTS: Among 8906 patients hospitalized in the ICU, 417 (4.7%) were LSP. At admission, male sex (adjusted odds-ratio (aOR) 1.4 [1.1; 1.7]), inpatient (aOR 2.0 [1.6; 2.4]) and in-ICU hospitalizations for respiratory (aOR 2.9 [1.6; 3.5]) or infectious diseases (aOR 1.6 [1.1; 2.5]) were all independently associated with a long stay in the ICU, while hospitalizations for metabolic (aOR 0.2 [0.1; 0.5]) or cardiovascular diseases (aOR 0.3 [0.2; 0.5]) were in favor of a short stay. In-ICU and in-hospital LSP mortality were 38.8% and 48.2%. Age (aOR 1.02 [1.00-1.04]), catecholamines (aOR 3.9 [1.9; 8.5]), renal replacement therapy (aOR 2.4 [1.3; 4.3]), primary disease-related complications (aOR 2.5 [1.4; 4.6]) and nosocomial infections (aOR 4.1 [1.8; 10.1]) were independently associated with mortality in LSP. CONCLUSION: LSP were highly comorbid patients mainly hospitalized for respiratory diseases. Their mortality was mostly related to nosocomial infections but the majority were discharged alive from the hospital.

OBJECTIVE: Preliminary data from different cohorts of small sample size or with short follow-up indicate poorer prognosis in people with obesity compared with other patients. This study aims to precisely describe the strength of association between obesity in patients hospitalized with coronavirus disease 2019 (COVID-19) and mortality and to clarify the risk according to usual cardiometabolic risk factors in a large cohort. METHODS: This is a prospective cohort study including 5,795 patients aged 18 to 79 years hospitalized from February 1 to April 30, 2020, in the Paris area, with confirmed infection by severe acute respiratory syndrome coronavirus 2. Adjusted regression models were used to estimate the odds ratios (ORs) and 95% CIs for the mortality rate at 30 days across BMI classes, without and with imputation for missing BMI values. RESULTS: Eight hundred ninety-one deaths had occurred at 30 days. Mortality was significantly raised in people with obesity, with the following ORs for BMI of 30 to 35 kg/m2 , 35 to 40 kg/m2 , and >40 kg/m2 : 1.89 (95% CI: 1.45-2.47), 2.79 (95% CI: 1.95-3.97), and 2.55 (95% CI: 1.62-3.95), respectively (18.5-25 kg/m2 was used as the reference class). This increase holds for all age classes. CONCLUSIONS: Obesity doubles mortality in patients hospitalized with COVID-19.

BACKGROUND: Complete airway closure during expiration may underestimate alveolar pressure. It has been reported in cases of acute respiratory distress syndrome (ARDS), as well as in morbidly obese patients with healthy lungs. The authors hypothesized that complete airway closure was highly prevalent in obese ARDS and influenced the calculation of respiratory mechanics. METHODS: In a post hoc pooled analysis of two cohorts, ARDS patients were classified according to body mass index (BMI) terciles. Low-flow inflation pressure-volume curve and partitioned respiratory mechanics using esophageal manometry were recorded. The authors' primary aim was to compare the prevalence of complete airway closure according to BMI terciles. Secondary aims were to compare (1) respiratory system mechanics considering or not considering complete airway closure in their calculation, and (2) and partitioned respiratory mechanics according to BMI. RESULTS: Among the 51 patients analyzed, BMI was less than 30 kg/m2 in 18, from 30 to less than 40 in 16, and greater than or equal to 40 in 17. Prevalence of complete airway closure was 41% overall (95% CI, 28 to 55; 21 of 51 patients), and was lower in the lowest (22% [3 to 41]; 4 of 18 patients) than in the highest BMI tercile (65% [42 to 87]; 11 of 17 patients). Driving pressure and elastances of the respiratory system and of the lung were higher when complete airway closure was not taken into account in their calculation. End-expiratory esophageal pressure (ρ = 0.69 [95% CI, 0.48 to 0.82]; P < 0.001), but not chest wall elastance, was associated with BMI, whereas elastance of the lung was negatively correlated with BMI (ρ = -0.27 [95% CI, -0.56 to -0.10]; P = 0.014). CONCLUSIONS: Prevalence of complete airway closure was high in ARDS and should be taken into account when calculating respiratory mechanics, especially in the most morbidly obese patients.

AIMS: Few studies describe recent changes in the prevalence, management, and outcomes of cardiogenic shock (CS) patients complicating acute myocardial infarction (AMI) in the era of widespread use of invasive strategies. The aim of the present study was to analyse trends observed in CS complicating AMI over the past 10 years, focusing on the timing of CS occurrence (i.e. primary CS, CS on admission vs. secondary CS, CS developed subsequently during hospitalization). METHODS AND RESULTS: Three nationwide French registries conducted and designed to evaluate AMI management and outcomes in 'real-life' practice included consecutive AMI patients (n = 9951) admitted to intensive cardiovascular care units (ICCUs) over a 1-month period, 5 years apart. The prevalence of CS complicating AMI decreased from 2005 to 2015: 5.9%, mean age 74.1 ± 12.7 in 2005; 4.0%, mean age 73.9 ± 12.7 in 2010, 2.8%, mean age 71.1 ± 15.0 in 2015 (P < 0.001). It decreased for both primary (1.8% to 1.0%) and secondary CS (4.1% to 1.8%). The profile of CS patients also changed over time with more patients presenting out-of-hospital cardiac arrest. In both primary and secondary CS, the use of percutaneous coronary intervention increased markedly over time, as did the use of mechanical ventilation and cardiac assist devices. Over the 10-year period, in-hospital mortality remained unchanged for both primary CS (41.8% to 37.8%) or secondary CS (57.3% to 58.8%). However, 1-year mortality decreased in patients with primary CS (from 60% to 37.8%, P = 0.038), and remained unchanged in patients developing secondary CS (from 64.5% to 69.1%, P = 0.731). CONCLUSION: Cardiogenic shock complicating AMI has become less frequent but, if present, CS, and particularly secondary CS, carries a very high mortality, which has not substantially improved over the past 10 years, in spite of the more frequent use of invasive strategies.

BACKGROUND: The use of hydroxocobalamin has long been advocated for treating suspected cyanide poisoning after smoke inhalation. Intravenous hydroxocobalamin has however been shown to cause oxalate nephropathy in a single-center study. The impact of hydroxocobalamin on the risk of acute kidney injury (AKI) and survival after smoke inhalation in a multicenter setting remains unexplored. METHODS: We conducted a multicenter retrospective study in 21 intensive care units (ICUs) in France. We included patients admitted to an ICU for smoke inhalation between January 2011 and December 2017. We excluded patients discharged at home alive within 24 h of admission. We assessed the risk of AKI (primary endpoint), severe AKI, major adverse kidney (MAKE) events, and survival (secondary endpoints) after administration of hydroxocobalamin using logistic regression models. RESULTS: Among 854 patients screened, 739 patients were included. Three hundred six and 386 (55.2%) patients received hydroxocobalamin. Mortality in ICU was 32.9% (n = 243). Two hundred eighty-eight (39%) patients developed AKI, including 186 (25.2%) who developed severe AKI during the first week. Patients who received hydroxocobalamin were more severe and had higher mortality (38.1% vs 27.2%, p = 0.0022). The adjusted odds ratio (95% confidence interval) of AKI after intravenous hydroxocobalamin was 1.597 (1.055, 2.419) and 1.772 (1.137, 2.762) for severe AKI; intravenous hydroxocobalamin was not associated with survival or MAKE with an adjusted odds ratio (95% confidence interval) of 1.114 (0.691, 1.797) and 0.784 (0.456, 1.349) respectively. CONCLUSION: Hydroxocobalamin was associated with an increased risk of AKI and severe AKI but was not associated with survival after smoke inhalation.

BACKGROUND: Oxygen therapy remains a cornerstone of treatment for acute heart failure in patients with pulmonary congestion. While avoiding hypoxaemia has long been a goal of critical care practitioners, less attention has been paid to the potential hazard related to excessive hyperoxia. AIM: To evaluate the impact of early hyperoxia exposure among critically ill patients hospitalized in an intensive care unit for acute heart failure. METHODS: In this preliminary study conducted in a Parisian intensive care unit, we assessed patients with acute heart failure admitted with pulmonary congestion and treated with oxygen therapy from 1 January 2015 to 31 December 2016. The hyperoxia group was defined by having at least one partial pressure of oxygen measurement>100mmHg on the first day following admission to the intensive care unit. The primary endpoint was 30-day all-cause mortality. Secondary endpoints were 30-day unplanned hospital admissions, occurrence of infections and intensive care unit and hospital lengths of stay. RESULTS: Seventy-five patients were included. Forty-three patients (57.3%) presented hyperoxia, whereas 32 patients (42.7%) did not (control group). The baseline clinical characteristics did not differ between the two groups. The primary endpoint was not statistically different between the two groups (14.0% in the hyperoxia group vs 18.8% in the control group; P=0.85). The secondary endpoints were also not significantly different between the two groups. In the multivariable analysis, hyperoxia was not associated with increased 30-day mortality (odds ratio 0.77, 95% confidence interval 0.24-2.41). CONCLUSION: In patients referred to an intensive care unit for acute heart failure, we did not find any difference in outcomes according to the presence of hyperoxia.

INTRODUCTION: The dramatic increase of the incidence of infections caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) has led to an increase of 50% of carbapenem consumption all around Europe in only 5 years. This favours the spread of carbapenem-resistant Gram-negative bacilli (GNB), causing life-threatening infections. In order to limit use of carbapenems for infections actually due to ESBL-PE, health authorities promote the use of rapid diagnostic tests of bacterial resistance. The objective of this work conducted in the intensive care unit (ICU) is to determine whether an early de-escalation of empirical carbapenems guided by the result of the ßLACTA test is not inferior to the reference strategy of de-escalating carbapenems after the antibiogram result has been rendered. METHODS AND ANALYSIS: This multicentre randomised controlled open-label non-inferiority clinical trial will include patients suffering from respiratory and/or urinary and/or bloodstream infections documented with GNB on direct examination and empirically treated with carbapenems. Empirical carbapenems will be adapted before the second dose depending on the results of the ßLACTA test performed directly on the microbiological sample (intervention group) or after 48-72 hours depending on the definite antibiogram (control group). The primary outcome will combine 90-day mortality and percentage of infection recurrence during the ICU stay. The secondary outcomes will include the number of carbapenems defined daily doses and carbapenem-free days after inclusion, the proportion of new infections during ICU stay, new colonisation of patients' digestive tractus with multidrug-resistant GNB, ICU and hospital length of stay and cost-effectiveness ratio. ETHICS AND DISSEMINATION: This protocol has been approved by the ethics committee of Paris-Ile-de-France IV, and will be carried out according to the principles of the Declaration of Helsinki and the Good Clinical Practice guidelines. The results of this study will be disseminated through presentation at scientific conferences and publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03147807.

BACKGROUND: Anti-synthetase (AS) and dermato-pulmonary associated with anti-MDA-5 antibodies (aMDA-5) syndromes are near one of the other autoimmune inflammatory myopathies potentially responsible for severe acute interstitial lung disease. We undertook a 13-year retrospective multicenter study in 35 French ICUs in order to describe the clinical presentation and the outcome of patients admitted to the ICU for acute respiratory failure (ARF) revealing AS or aMDA-5 syndromes. RESULTS: From 2005 to 2017, 47 patients (23 males; median age 60 [1st-3rd quartiles 52-69] years, no comorbidity 85%) were admitted to the ICU for ARF revealing AS (n = 28, 60%) or aMDA-5 (n = 19, 40%) syndromes. Muscular, articular and cutaneous manifestations occurred in 11 patients (23%), 14 (30%) and 20 (43%) patients, respectively. Seventeen of them (36%) had no extra-pulmonary manifestations. C-reactive protein was increased (139 [40-208] mg/L), whereas procalcitonine was not (0.30 [0.12-0.56] ng/mL). Proportion of patients with creatine kinase ≥ 2N was 20% (n = 9/47). Forty-two patients (89%) had ARDS, which was severe in 86%, with a rate of 17% (n = 8/47) of extra-corporeal membrane oxygenation requirement. Proportion of patients who received corticosteroids, cyclophosphamide, rituximab, intravenous immunoglobulins and plasma exchange were 100%, 72%, 15%, 21% and 17%, respectively. ICU and hospital mortality rates were 45% (n = 21/47) and 51% (n = 24/47), respectively. Patients with aMDA-5 dermato-pulmonary syndrome had a higher hospital mortality than those with AS syndrome (n = 16/19, 84% vs. n = 8/28, 29%; p = 0.001). CONCLUSIONS: Intensivists should consider inflammatory myopathies as a cause of ARF of unknown origin. Extra-pulmonary manifestations are commonly lacking. Mortality is high, especially in aMDA-5 dermato-pulmonary syndrome.
