High Plasma Concentration of Non-Esterified Polyunsaturated Fatty Acids Is a Specific Feature of Severe COVID-19 Pneumonia
2020
Background: The pathogenesis of severe COVID-19 is frequently associated with an uncontrolled inflammatory response. Severe forms of COVID-19 appear to be more frequent in obese patients, but an association with metabolic disorders is not established. Here, we focused on lipoprotein metabolism in patients hospitalized for severe pneumonia, depending on COVID-19 status. Methods: Thirty-four non-COVID-19 and 27 COVID-19 patients with severe pneumonia were enrolled. Most of them required intensive care. Plasma lipid levels, lipoprotein metabolism, and clinical and biological features were assessed. Findings: Despite similar initial metabolic comorbidities and respiratory severity, COVID-19 pat…
Social deprivation and 1‐year survival after stroke: a prospective cohort study
2020
BACKGROUND Social deprivation may have a deleterious influence on post-stroke outcomes, but available data in the literature are mixed. AIM The aim of this cohort study was to evaluate the impact of social deprivation on 1-year survival in patients with first-ever stroke. METHODS Social deprivation was assessed at individual level with the EPICES score, a validated multidimensional questionnaire, in 1312 patients with ischemic stroke and 228 patients with spontaneous intracerebral hemorrhage, who were prospectively enrolled in six French study centers. Baseline characteristics including stroke severity and pre-stroke functional status were collected. Multivariable Cox models were generated …
Higher risk of death among MEN1 patients with mutations in the JunD interacting domain: a Groupe d'etude des Tumeurs Endocrines (GTE) cohort study.
2013
International audience; Multiple endocrine neoplasia syndrome type 1 (MEN1), which is secondary to mutation of the MEN1 gene, is a rare autosomal-dominant disease that predisposes mutation carriers to endocrine tumors. Although genotype-phenotype studies have so far failed to identify any statistical correlations, some families harbor recurrent tumor patterns. The function of MENIN is unclear, but has been described through the discovery of its interacting partners. Mutations in the interacting domains of MENIN functional partners have been shown to directly alter its regulation abilities. We report on a cohort of MEN1 patients from the Groupe d'étude des Tumeurs Endocrines. Patients with a…
Is the pelvis-thorax coordination a valuable outcome instrument to assess patients with Hip osteoarthritis?
2020
Objective: The evaluation of the disease severity in hip osteoarthritis (OA) patients being currently based on subjective instruments. It would be of interest to develop more objective instruments, for example based on gait analysis. The aims of this study were to explore if pelvis-thorax coordination parameters could be valuable instrument outcomes to achieve this evaluation by assessing their reliability, discriminant capacity and responsiveness. Methods: Three groups of subjects; healthy, hip OA patients with severe disease (defined as indication to surgery), hip OA patients with less severe disease (no indication to surgery) were included. Hip OA patients with severe disease were evalua…
Impact du tabagisme sur le pronostic fonctionnel après AVC ischémiques en fonction de la précarité, une étude de cohorte prospective
2020
Etat de la question Bien que le tabagisme soit un facteur de risque connu des accidents vasculaires cerebraux (AVC) ischemiques, son influence sur le pronostic post-AVC demeure controverse. Ces disparites peuvent etre expliquees par la presence de facteurs de confusion insuffisamment pris en compte, notamment la precarite. Cette etude visait a evaluer l’impact conjoint de la precarite et du tabagisme sur le pronostic fonctionnel apres un AVC ischemique en s’appuyant sur les donnees de l’etude de cohorte prospective INDIA (Inegalites sociales et pronostic des patients hospitalises pour AVC dans quatre departements francais contrastes). Materiel et methodes De 2010 a 2014, 1536 patients avec …
Correction to: The dysregulated innate immune response in severe COVID-19 pneumonia that could drive poorer outcome
2021
Although immune modulation is a promising therapeutic avenue in coronavirus disease 2019 (COVID-19), the most relevant targets remain to be found. COVID-19 has peculiar characteristics and outcomes, suggesting a unique immunopathogenesis.Thirty-six immunocompetent non-COVID-19 and 27 COVID-19 patients with severe pneumonia were prospectively enrolled in a single center, most requiring intensive care. Clinical and biological characteristics (including T cell phenotype and function and plasma concentrations of 30 cytokines) and outcomes were compared.At similar baseline respiratory severity, COVID-19 patients required mechanical ventilation for significantly longer than non-COVID-19 patients …
Vaccination Against Hepatitis B Virus (HBV) in HIV-1-Infected Patients With Isolated Anti-HBV Core Antibody: The ANRS HB EP03 CISOVAC Prospective Stu…
2016
International audience; Although an isolated anti-hepatitis B virus (HBV) core antibody (anti-HBc) serological profile is frequent in human immunodeficiency virus (HIV)-infected patients, data on HBV vaccination in these patients are scarce. A prospective multicenter study was conducted to assess the immunogenicity of HBV vaccination in 54 patients with an isolated anti-HBc profile and undetectable HIV load. They were vaccinated with 1 dose (20 µg) of recombinant HBV vaccine. Those with an anti-HBV surface antibody (anti-HBs) level of 100 mIU/mL 4 weeks after a single recall dose of HBV vaccine should be further vaccinated with a reinforced triple double-dose scheme.
Les facteurs pronostiques du traumatisme sévère en fonction de la sévérité de l’atteinte thoracique
2017
Etat de la question Le traumatisme severe est associe a un risque eleve de morbidite et de mortalite. L’atteinte thoracique est souvent presente. Le but de l’etude etait de determiner si les facteurs pronostiques du traumatisme severe sont modifies par la severite de l’atteinte thoracique. Materiel et methodes Une analyse ancillaire de l’etude FIRST, une cohorte multicentrique incluant des patients ayant un traumatisme severe necessitant une admission a dans l’une des reanimations des centres hospitalo-universitaires (CHU) participants dans les 72 heures post-traumatiques. Les patients admis initialement dans un hopital general ont ete exclus. Resultats Parmi les 2052 patients analyses, 583…
Specific Features of the Coagulopathy Signature in Severe COVID-19 Pneumonia
2021
Rationale: COVID-19 displays distinct characteristics that suggest a unique pathogenesis. The objective of this study was to compare biomarkers of coagulopathy and outcomes in COVID-19 and non-COVID-19 patients with severe pneumonia.Methods: Thirty-six non-COVID-19 and 27 COVID-19 non-immunocompromised patients with severe pneumonia were prospectively enrolled, most requiring intensive care. Clinical and biological characteristics (including plasma biomarkers of coagulopathy) were compared.Results: At similar baseline severity, COVID-19 patients required mechanical ventilation (MV) for significantly longer than non-COVID-19 patients (p = 0.0049) and more frequently developed venous thrombot…
Vasopressor Cumulative Dose Requirement and Risk of Early Death During Septic Shock: An Analysis From The EPISS Cohort
2018
Septic shock is the primary cause of death in intensive care units, with about 20% of patients dying in the first 3 days. To design future trials focused on early mortality, we require knowledge of early indicators that can detect patients at high risk of early death from refractory septic shock.The aim of this study was to assess whether the cumulative dose of vasopressors (CDV), calculated as the cumulative dose of epinephrine + norepinephrine, is a predictor of early death (within 72 hours) attributable to refractory septic shock (EDASS). This substudy of the EPISS trial was based on 370 patients admitted to a French ICU for septic shock between 2009 and 2011. The area under the receivin…
