Background: While acute severe asthma (ASA) is the leading cause of emergency department visits and the third cause of hospitalization in children younger than 18 years old, there is a lack of data regarding adult patients admitted in intensive care units (ICU) for ASA. We aimed to describe the evolutions in epidemiology, management, and outcomes of ASA in adult patients, over a period of twenty years in the Greater Paris area ICUs (CUB-Réa Database). Methods: Demographics, severity and supportive treatments were collected from the CUB-Réa Database. The primary endpoint was the prevalence of ASA by periods of 5 years. The secondary endpoints were in-ICU survival, in-hospital survival, use of mechanical ventilation including non-invasive and invasive and catecholamine. Multivariate analysis was performed to assess correlating factors of ICU Mortality. Results: Of the 475 357 ICU admissions from January 1997 to January 2016, 7049 were admitted for ASA with a decreasing prevalence over time, respectively 2.8%, 1.7%, 1.1%, and 1.1% of total ICU admissions (p Conclusion: ICU admission for ASA remains uncommon and decreases over time. Despite an increasing severity of patients and the use of mechanical ventilation, the use of catecholamine decreases with high in-ICU survival rate which could be related to a better management of mechanical ventilation.

Le sepsis est un problème de santé publique majeur, associé à une morbi-mortalité conséquente. La forme la plus sévère du sepsis, le choc septique, a une physiopathologie complexe, associant entre autres anomalies une insuffisance corticotrope et une réponse inflammatoire exagérée. Les corticoïdes, médicaments aux effets pléiotropes, corrigent cette insuffisance corticotrope et exhibent un effet anti-inflammatoire. Les corticoïdes sont à l’heure actuelle un des rares médicaments possiblement capables de réduire la mortalité dans le choc septique. S’ajoute à cet effet bénéfique sur la mortalité un effet hémodynamique favorable. L’administration de corticoïdes à faibles doses et sur une courte période est associée à remarquablement peu d’effets secondaires. Un traitement par hydrocortisone 200mg/j peut être administré chez les patients en choc septique. Nous suggérons l’administration de ce traitement en bolus intraveineux intermittent pendant sept jours sans sevrage progressif à la fin de cette période. Un minéralocorticoïde, la fludrocortisone, peut être associée au traitement par hydrocortisone dans les états de choc réfractaire. La recherche de biomarqueurs permettant d’identifier précisément une population répondant aux corticoïdes dans le choc septique est une thématique porteuse.

BackgroundEarly prognostication in trauma patients is challenging, but particularly important. We wanted to explore the ability of copeptin, the C-terminal fragment of arginine vasopressin, to identify major trauma, defined as Injury Severity Score (ISS) > 15, in a heterogeneous cohort of trauma patients and to compare its performances with lactate. We also evaluated copeptin performance in predicting other clinical outcomes: mortality, hospital admission, blood transfusion, emergency surgery, and Intensive Care Unit (ICU) admission.MethodsThis single center, pragmatic, prospective observational study was conducted at Arcispedale Santa Maria Nuova, a level II trauma center in Reggio Emilia, Italy. Copeptin determination was obtained on Emergency Department (ED) arrival, together with venous lactate. Different outcomes were measured including ISS, Revised Trauma Score (RTS), hospital and ICU admission, blood transfusion, emergency surgery, and mortality.ResultsOne hundred and twenty five adult trauma patients admitted to the ED between June 2017 and March 2018. Copeptin showed a good ability to identify patients with ISS > 15 (AUC 0.819). Similar good performances were recorded also in predicting other outcomes. Copeptin was significantly superior to lactate in identifying patients with ISS > 15 (P0.0015), and in predicting hospital admission (P0.0002) and blood transfusion (P0.016). Comparable results were observed in a subgroup of patients with RTS 7.84.ConclusionsIn a heterogeneous group of trauma patients, a single copeptin determination at the time of ED admission proved to be an accurate biomarker, statistically superior to lactate for the identification of major trauma, hospital admission, and blood transfusion, while no statistical difference was observed for ICU admission and emergency surgery. These results, if confirmed, may support a role for copeptin during early management of trauma patients.

Background: Increased left ventricular afterload during peripheral venoarterial-extracorporeal membrane oxygenation (VA-ECMO) support frequently causes hydrostatic pulmonary oedema. Because physiological studies demonstrated left ventricular afterload decrease during VA-ECMO assistance combined with the intra-aortic balloon pump (IABP), we progressively changed our standard practice systematically to associate an IABP with VA-ECMO. This study aimed to evaluate IABP efficacy in preventing pulmonary oedema in VA-ECMO-assisted patients. Methods: A retrospective single-centre study. Results: Among 259 VA-ECMO patients included, 104 received IABP. Weinberg radiological score-assessed pulmonary oedema was significantly lower in IABP+ than IABP– patients at all times after ECMO implantation. This protection against pulmonary oedema persisted when death and switching to central ECMO were used as competing risks (subhazard ratio 0.49, 95% confidence interval (CI) 0.33–0.75; P+ patients (2.2±4.3 vs. 0.7±2.0 days; P=0.0003). Less frequent pulmonary oedema and more days off mechanical ventilation were also confirmed in 126 highly comparable IABP+ and IABP– patients, propensity score matched for receiving an IABP. Conclusions: Associating an IABP with peripheral VA-ECMO was independently associated with a lower frequency of hydrostatic pulmonary oedema and more days off mechanical ventilation under ECMO.

Differences between BD-I and BD-II patients with regard to specific illness characteristics are poorly understood. This study is mainly aimed to compare socio-demographic and clinical characteristics between BD-I and BD-II patients with the goal of clarifying possible predictors of clinical course. The sample of this cohort study is composed of 391 currently euthymic bipolar patients. Participants were all receiving only maintenance treatment; their psychopharmacological regimens and psychopathological conditions were stable at assessment. After univariate analyses, BD-II patients were more likely to be female, had more frequently a recent depressive episode and substance abuse/dependence relative to BD-I subjects. BD-II patients were also less likely to have a positive history of psychiatric conditions in family, psychotic symptoms at first episode, and first depressive illness episode. Moreover, BD-II were older at their illness onset and first treatment than BD-I patients. Furthermore, BD-I were more likely to have higher depressive, manic, anxiety, and symptoms severity than BD-II patients. After logistic regression analyses, being female (OR = 0.289), having psychiatric conditions in family (OR = 0.273), and higher severity of illness at CGI (OR = 0.604) were all significantly associated with BD-II. Additional studies are required to replicate these results, and facilitate the prediction of BD outcomes according to the specified profile.

Objective Specific predictors of relapse/recurrence in major depressive disorder (MDD) have been identified but evidence across studies are inconsistent. This study aimed to identify the most relevant socio-demographic/clinical predictors of MDD recurrence in a sample of 508 outpatients. Methods This naturalistic cohort study included 508 currently euthymic MDD patients (mean age = 54.1 ± 16.2) of which 53.9% had a single and 46.1% recurrent depressive episodes. A detailed data collection was performed and illness histories were retraced through clinical files and lifetime computerized medical records. Results Compared to patients with single episode, MDD patients with recurrent episodes significantly differ regarding current age, gender, working status, positive history of psychiatric disorders in family, first-lifetime illness episode characteristics, first-episode and current psychotic symptoms, current melancholic features and seasonality, age at first treatment, duration of untreated illness, and comorbid cardiovascular/endocrinological conditions. However, after multivariate analyses controlling for current age, gender, educational level, working status differences, psychiatric conditions in family, and age of illness episode, recurrence was associated with older age (p ≤ .001), younger age at first treatment (p ≤ .005), being treated with previous psychoactive treatments (p .001), and longer duration of untreated illness (p .001). Conclusions The variables associated with MDD recurrence identified in the current study may aid in the stratification of patients who could benefit from more intensive maintenance treatments for MDD. However, clinicians should rapidly identify cases that are not likely to recur in order to avoid unnecessary treatments which are commonly considered as the standard of care.

International audience; Objective: Mobile extracorporeal membrane oxygenation (ECMO) retrieval teams (MERTs) assure ECMO implantation and under-ECMO retrieval of patients with most severe acute respiratory failure (ARF) to experienced ECMO centers. Although described as feasible, mobile ECMO has only been poorly evaluated in comparison with on-site implantation. This study was undertaken to compare the indications, characteristics, and outcomes of MERT-implanted patients with venovenous (VV)-ECMO versus those implanted on site in our intensive care unit (ICU).Methods: Retrospective, single-center study.Results: Among 157 VV-ECMO implantations from 2008 to 2012, the MERT hooked up 118 (75%) patients with refractory ARF, as reflected by their median partial pressure of O2 in arterial blood/fraction of inspired oxygen of 58 (interquartile range, 50-73). ARF was accompanied by severe multiorgan failure, with a median Simplified Acute Physiology Score-II of 71 (61-81), median Sequential Organ Failure Assessment score of 14 (10-16), and with 82% of the patients receiving inotropes. All patients were transported by ground ambulance: median distance was 15 (6-25) km, and median transport time was 35 (25-35) minutes, during which no major ECMO system-related event occurred. For the MERT- and on-site-implanted groups, ICU mortality was comparable (46.6% vs 53.8%, respectively, P = .5), as were ECMO-related complication rates (53.4% of MERT vs 53.8% of on-site-implanted groups, P = 1.0). According to multivariable analysis, MERT ECMO implantation was not associated with ICU mortality (odds ratio, 1.1; 95% confidence interval, 0.4-2.7; P = .85).Conclusions: ICU mortality and ECMO-related complications of patients with MERT-implanted VV-ECMO who were transferred to our ECMO referral center were comparable with those implanted on site by the same team, thereby supporting this strategy to manage patients with severe ARF.

Introduction The aim of this study was to identify clinical variables which may be independently associated with positivity of a cardiac troponin I (cTnI) assay in a large population of patients admitted to the emergency department (ED). Materials and methods 3166 subjects, with at least two troponin I tests ordered within 6 hours in the ED, were studied. Patient data were statistically analyzed to identify clinical associations with increased values of Troponin I. Results Although patients with diagnosis of acute coronary syndrome displayed troponin I values significantly higher than those of other groups, positivity to troponin I (>40 ng/L) was also observed in patients with other clinical conditions. In multivariate analysis, age, elevated heart rate and electrocardiographic changes were independently associated with troponin I positivity at admission. In the whole study population troponin I positivity exhibited high sensitivity and negative predictive value, counterbalanced by low specificity and limited positive predictive value. Conclusions Troponin I positivity should be combined with history and clinical evaluation and cautiously interpreted in the ED, especially in patients exhibiting factors associated with higher troponin I levels such as older age, elevated heart rate or ECG changes.

Introduction: Two Italian adults arrived at the Emergency Department referring diarrhea, nausea and vomiting for 4 days; weakness, fatigue and visual hallucinations were also complained of. Patients reported the ingestion of some leaves of a plant, which they supposed to be “donkey ears”, a week before. Physical examination showed hypotension and bradycardia and ECG examination disclosed sinus rhythm and repolarization abnormalities (scooping of the ST-T complex) in both patients and a 2:1 AV block in the man. Materials and methods: Digoxin concentration was evaluated twice for each patient (at the admission and after 4 hours) by the automated immunoassay system ADVIA Centaur®. Digitoxin concentration was evaluated by liquid chromatography-mass spectrometry (LC-MS/MS). Results: Despite clinical picture was suggestive of digitalis intoxication, digoxin levels were undetectable. Due to the more severe clinical picture, the male patient was treated with anti-digoxin antibodies (Digifab®) achieving a good clinical improvement and remission of the AV block within two hours. Initial diagnosis was confirmed by LC-MS/MS showing high digitoxin concentrations, but digoxin was undetectable. Patients remained stable and 48 hours later were discharged from the hospital. Conclusion: Whereas digoxin determination frequently relies on monoclonal antibodies which do not cross-react to digitoxin, polyclonal antibodies constituting Digifab® recognize a large spectrum of cardiac glycosides, including digitoxin. This report emphasizes the primary role of the clinical approach to patients in the emergency setting and how an active communication and a continuous sharing of professional experiences between Laboratory and Clinicians ensure an early and correct diagnosis.
