Project description:Acute cardiac injuries occur in 20%–25% of hospitalized COVID‐19 patients. Herein, we demonstrate that human cardiac organoids (hCOs) are a viable platform to model the cardiac injuries caused by COVID‐19 hyperinflammation. As IL‐1β is an upstream cytokine and a core COVID‐19 signature cytokine, it was used to stimulate hCOs to induce the release of a milieu of proinflammatory cytokines that mirror the profile of COVID‐19 cytokine storm. The IL‐1β treated hCOs recapitulated transcriptomic, structural, and functional signatures of COVID‐19 hearts. The comparison of IL‐1β treated hCOs with cardiac tissue from COVID‐19 autopsies illustrated the critical roles of hyper‐inflammation in COVID‐19 cardiac insults and indicated the cardioprotective effects of endothelium. The IL‐1β treated hCOs thus provide a defined and robust model to assess the efficacy and potential side effects of immunomodulatory drugs, as well as the reversibility of COVID‐19 cardiac in- juries at baseline and simulated exercise conditions.

Project description:Since December 2019, a novel Coronavirus (SARS-CoV-2) was confirmed as the etiologic agent of a worldwide outbreak of a pneumonia that can result in severe respiratory failure. This clinical entity seems to be associated with a marked hypercoagulable state that causes both arterial and venous thromboembolic complications. Therefore, an adequate anti-thrombotic prophylaxis is recommended in hospitalized COVID-19 patients. Although rapidly worsening respiratory symptoms in a patient with SARS-CoV-2 respiratory infection may correlate with worsening pneumonia itself, it may also mask a pulmonary embolism. We report the case of a 50-year-old man affected by SARS-CoV-2 pneumonia, who developed acute pulmonary embolism.

Project description:Recent reports have suggested an increased risk of pulmonary embolism (PE) related to COVID-19. The aim of this cohort study is to compare the incidence of PE during a 3-year period and to assess the characteristics of PE in COVID-19. We studied consecutive patients presenting with PE (January 2017–April 2020). Clinical presentation, computed tomography (CT) and biological markers were systematically assessed. We recorded the global number of hospitalizations during the COVID-19 pandemic and during the same period in 2018-2019. We included 347 patients: 326 without COVID-19 and 21 with COVID-19. Patients with COVID-19 experienced more likely dyspnea (p=0.04), had lower arterial oxygen saturation (p<0.001), higher C-reactive protein and white blood cell (WBC) count (p<0.0001 and p=0.001, respectively), and a significantly higher in-hospital mortality (14% versus 3.4%, p=0.04). Among COVID-19 patients, diagnosis of PE was performed at admission in 38% (n=8). COVID-19 patients with diagnosis of PE during hospitalization (n=13) had significantly more dyspnea (p=0.04), lower arterial oxygen saturation (p=0.01), less proximal PE (p=0.02), and higher heart rate (p=0.009), CT severity score (p=0.001), C-reactive protein (p=0.006) and WBC count (p=0.04). During the COVID-19 outbreak, a 97.4% increase of PE incidence was observed as compared to 2017–2019 and the proportion of hospitalizations related to PE was 3.7% versus 1.3% in 2018–2019 (p<0.0001). In conclusion, the COVID-19 pandemic leads to a dramatic increased incidence of PE. Physicians should be aware that PE may be diagnosed at admission, but also after several days of hospitalization, with a different clinical, CT and biological features of thrombotic disease.

Project description:As a primary target of SARS-CoV-2, lung exhibits heterogeneous histopathological changes following infection. However, comprehensive insight into their protein basis with spatial resolution remains deficient, which hinders further understanding of COVID-19-related pulmonary injury. Here, we generated a region-resolved proteomic atlas of hallmark pathological pulmonary structures by integrating histological examination, laser microdissection, and ultrasensitive proteomics. Over 10,000 proteins were quantified across 71 post-mortem specimens. We identified a spectrum of pathway dysregulations in alveolar epithelium, bronchial epithelium, and blood vessels comparing with non-COVID-19 controls, providing evidence for transitional-state pneumocyte hyperplasia. Additionally, our data revealed the region-specific enrichment of functional markers in bronchiole mucus plug, pulmonary fibrosis, airspace inflammation, and alveolar type 2 cells, uncovering their distinctive features. Furthermore, we detected increased protein expression associated with viral entry and inflammatory response across multiple regions, suggesting potential therapeutic targets. Collectively, this study provides a unique perspective for deciphering COVID-19-caused pulmonary dysfunction by spatial proteomics.

Project description:Introduction The COVID-19 epidemic has led to the need for unprecedented decisions to be made to maintain the provision of neurological care. This article addresses operational decision-making during the epidemic. Development We report the measures taken, including the preparation of a functional reorganisation plan, strategies for hospitalisation and emergency management, the use of telephone consultations to maintain neurological care, provision of care at a unit outside the hospital for priority patients, decisions about complementary testing and periodic in-hospital treatments, and the use of a specific telephone service to prioritise patients with epileptic seizures. Conclusion Despite the situation of confinement, neurology departments must continue to provide patient care through different means of operation. Like all elements of management, these must be evaluated.

Project description:Coronaviruses disease 2019 (COVID-19) is the most crucial threat, the world has ever witnessed. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of this disease pandemic. The World Health Organization has confirmed the continuing epidemic as a worldwide public health crisis. Presently, the research on COVID-19 is even in the primitive stage. Studies on unveiling the natural route of COVID-19 infection and related pathophysiology, the biology of pulmonary airways pose a more rational restorative approach in the management of COVID-19. Thus, based on the existing facts, we methodically reviewed the efforts put forth by various research institutes, pharmaceutical companies and biotechnology firms in pulmonary delivery to prevent and control the COVID-19. This article would be valuable for the healthcare community, which is efficiently dealing with the SARS-CoV-2 crisis.

Project description:During the COVID-19 epidemic, the prevalence of the disease means that practically any lung opacity on an X-ray could represent pneumonia due to infection with SARS-CoV-2. Nevertheless, atypical radiologic findings add weight to negative microbiological or serological tests. Likewise, outside the epidemic wave and with the return of other respiratory diseases, radiologists can play an important role in decision making about diagnoses, treatment, or preventive measures (isolation), provided they know the key findings for entities that can simulate COVID-19 pneumonia. Unifocal opacities or opacities located in upper lung fields and predominant airway involvement, in addition to other key radiologic and clinical findings detailed in this paper, make it necessary to widen the spectrum of possible diagnoses.

Project description:La COVID-19 peut comporter des troubles neurologiques qui se partagent en 5 grands groupes : des encéphalopathies, souvent avec agitation, confusion, troubles psychotiques, dont la physiopathogénie est sans doute multiple (syndrome inflammatoire général lié au sepsis, hypoxie, insuffisance rénale, hypercoagulabilité, agression directe du virus) ; des syndromes dysimmunitaires du système nerveux central (encéphalomyélites aiguës disséminées, plus rarement syndrome de Miller–Fisher, encéphalite aiguë nécrosante hémorragique…) ; des AVC, majoritairement ischémiques, dont la COVID-19 est un facteur de risque indépendant, probablement par des phénomènes d’hypercoagulabilité ; des syndromes de Guillain–Barré ; des atteintes diverses de nerfs crâniens ou des nerfs périphériques. L’anosmie, qui est très fréquente, est le plus souvent due à une atteinte de l’épithélium olfactif mais peut être due à une extension de l’agression virale au nerf et au cortex olfactifs. Des études complémentaires restent nécessaires pour mieux comprendre la physiopathogénie et, donc, la prévention et le traitement de ces complications neurologiques dues à la COVID-19.

Project description:Introduction L’âge, facteur principal de la COVID-19 sévère/mortelle, explique que les résidents des EHPAD, âgés et/ou comorbides, soient à risque. L’ivermectine (IVM), anti-parasitaire, a montré une activité antivirale anti-SARS-CoV-2 in vitro (étude australienne). La moxidectine (MOX) pourrait aussi être intéressante (demi-vie longue). Lors d’une épidémie de gale en EHPAD où les résidents ont reçu de l’IVM orale, nous rapportons son impact sur la Covid-19 survenue en parallèle. Observation Le 6/03/20 : patiente de 66 ans = résidente-1, EHPAD-A (Seine-et-Marne, 77), hospitalisée pour gale profuse. Incluse dans l’essai contrôlé randomisé (ECT) « gale CRUSTED ; NCT02841215 », a reçu 3 doses d’IVM (400 ou 200 ?g/kg en insu ; J0-J7-J14). Trois autres résidents avaient une gale ; et résidents et personnels ont reçu IVM 200 ?g/kg J0–J7 (n = 121). Retour de la résidente-1 à l’EHPAD-A le 17/03 (plan blanc). Étude épidémiologique : Les cas probables ou confirmés (PCR) de COVID-19 de l’EHPAD-A entre 5/03 et 15/05 ont été identifiés, facteurs de risque, sévérité et mortalité précisés. Durant cette période, les infections COVID-19 et décès des autres EHPAD du 77 étaient déclarés à l’ARS. Une comparaison EHPAD-A et contrôles (EHPAD du 77 comparables en âge, effectif et tarif) était réalisée. Étude virologique in vitro : Mesure de l’activité anti-SARS-CoV-2 de l’IVM et MOX sur cellules VeroE6 à doses croissantes (0,05–10 ?M) par quantification ARN et immunofluorescence ; viabilité des cellules surveillée. Résultats Soixante-neuf résidents (incluant résidente-1) et 52 personnels EHPAD-A ont reçu l’IVM : âge médian résidents 90 ans (84–94), 78,3 % femmes, 98,6 % au moins une comorbidité à risque de COVID-19 sévère. 11 sujets présentaient une COVID-19 probable ou certaine (7/69 résidents et 4/52 personnels, fréquence 10,1 %). Parmi les résidents, 90,9 % (10/11) ont eu une COVID-19 minime, sans oxygène ou hospitalisation, aucun mort. Parmi les 177 EHPAD du 77, 45 étaient inclus comme contrôles, soit 3062 résidents (âge médian 86,2 ans, 77,3 % femmes). Parmi eux, 22,6 % [95 %IC 16,3-28,9] ont eu la COVID-19 vs. 1,4 % EHPAD-A avec une mortalité attribuable de 4,9 % [95 %IC 3,2-6,5] vs. 0 % EHPAD-A. Une activité antivirale majeure in vitro de l’IVM et MOX (EC50 IVM 0,14 ± 0,02 ?M et MOX 0,48 ?M ± 0,08 ?M) avec viabilité cellulaire préservée était observée. Discussion Tous les cas observés de COVID-19 dans l’EHPAD-A « traité » par IVM étaient mineurs, sans décès durant la période d’étude, alors que les résidents des EHPAD « contrôles » (sans IVM), appariés selon âge, effectif et niveau socio-économique, ont montré une fréquence de COVID-19 et une mortalité plus élevées. L’IVM pourrait avoir un rôle protecteur (suggéré depuis dans étude US), conforté par l’étude virologique. Malgré les limites –caractère observationnel et absence de corrélation démontrée in vitro/in vivo–, la plausibilité est suffisante pour réaliser un ECT en cluster de prévention par IVM et MOX en EHPAD.
