Filter by:The COVID epidemics is responsible for a huge number of death following COVID acute respiratory failure. First instance treatment includes oxygenotherapy up to 15L/min in spontaneous ventilation. However COVID infection can ultimately lead to an acute respiratory distress syndrome (ARDS) requiring mechanical ventilation in the intensive care unit (ICU). Guidelines on ARDS management are based on small ventilation volume (6 mL/kg), a pulmonary end expiratory pressure (PEEP) chosen to get the best pulmonary compliance, a plateau pressure lower than 30 cm of water and daily prone positioning when PaO2/FiO2 ratio is lower than 150. In ventilated ARDS patients, prone positioning has shown survival improvement. Though they applied this optimized management of ARDS patients, Chinese intensivists have recently reported mortality rate higher than 50% in ARDS COVID patients requiring intubation and mechanical ventilation. Before being intubated and admitted to ICU, COVID patients require increasing rate of oxygen delivery. From the start of the epidemics, we have observed that an oxygenotherapy rate higher than 3L/min at the initial phase of the disease was associated with a high risk of severe acute respiratory distress (30%) The investigators hypothesize that prone positioning in patients in spontaneous ventilation (not tubed) from the stage of oxygenotherapy higher than 3L/min (to get an SpO2 of 95% or higher) would prevent respiratory worsening and the need for intubation. Prone positioning is easy to apply in patients in spontaneous ventilation since they can change position by themselves.
The objectives of this intermediate-size expanded access protocol are to assess the safety and efficacy of remestemcel-L in participants with ARDS due to coronavirus infection 2019 (COVID-19).
The COVID-19 epidemic has a major impact on the organization of hospital structures as a whole. Regarding the functioning of the Maternities, it was decided by the three Maternities of AP-HP. Sorbonne University of the Pitié-Salpêtrière, Trousseau and Tenon sites, from March 20, 2020 to no longer authorize visits during the stay of mothers following childbirth. This prohibition has also been extended to spouses. This measure was guided by a concern to protect both the patients, their newborn and the entire staff of the aftermath. The period surrounding a birth is a period of strong emotional impact with an incidence of postpartum depression estimated at 15% in the general population (1). The separation of women from their spouses during this period could expose them to greater psychological vulnerability. In addition, when they return home, the patients will be isolated from their relatives due to the quarantine, which is an additional risk factor for postpartum depression. The teams of the three maternity units of AP-HP. Sorbonne University have organized themselves to be able to respond to situations of mental vulnerability during their stay with the intervention of maternity psychologists and psychiatrists and child psychiatrists as is done in the treatment usual charge. In addition, anticipating situations of greater vulnerability linked to the health crisis, the Maternity teams decided to set up a follow-up of patients after their return home through a telephone interview with psychologists or student psychologists in Master at D10 - D12 and 6-8 weeks postpartum in order to identify patients at increased risk of postpartum depression and to set up appropriate management if necessary for these patients. We therefore propose through this project to describe the consequences of this separation from the spouse during the postpartum stay and then with the family after returning home within the context of quarantine by assessing the incidence of post-partum depression during this sanitary crisis. A telephone interview of all the patients will be proposed on D10 - D12 and at 6-8 weeks postpartum using specific questionnaire to calculate a score of depression. This early identification will allow the establishment of an adapted psychological follow-up.
This phase I/II trial studies low-dose radiation therapy as a focal anti-inflammatory treatment for patients with pneumonia or SARS associated with COVID-19 infection.
The coronavirus disease of 2019 (COVID-19) is a viral illness caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), now deemed a pandemic by the World Health Organization. Some COVID-19 patients may develop coagulopathy which is associated with poor prognosis and high risk of thrombosis. Some patients develop severe thrombotic complications, such as pulmonary embolism, despite anti-thrombotic prophylaxis by low molecular weight heparin. The aim of this project is to evaluate modified thromboelastometry for identifying patients at high risk of thrombosis. The hypothesize is that hypofibrinolysis with increased plasma PAI-1, TAFI (thrombin-activatable fibrinolysis inhibitor ) levels in association with high thrombin generation may explain high incidence of thrombosis in this population. A simple laboratory assay, widely available in hospitals, such as thromboelastometry, might be of great clinical interest to detect Covid-19 patients with high risk of thrombosis. In order to make ROTEM more sensitive to hypofibrinolysis, exogenous t-PA will be added in the assay. The preliminary results showed that patients with Covid-19 have significant hypercoagulability detectable with ROTEM and Covid-19 patients with thrombosis have both hypercoagulability and hypofibrinolysis.
The COVID-19 pandemic poses a major and imminent challenge for health care systems regarding patient triage and allocation of limited resources worldwide. The involved pathogenetic mechanisms as well as the clinical value of established and emerging biomarkers for early risk prediction are largely unknown. To fill these gaps in knowledge, investigators designed the prospective, interdisciplinary, observational, case-control "COronaVIrus surviVAl (COVIVA)" study platform, aiming to deliver an open-source platform to i) perform extensive clinical and biomarker phenotyping in COVID-19 suspects presenting to the emergency department (ED) as well as admitted to the intensive care unit, ii) compare clinical and biomarker profiles of COVID-19 patients with a control group, iii) derive and validate personalized risk prediction models for early clinical decision support, and iv) explore pathophysiological mechanisms including but not limited to inflammatory, immunological and cardiovascular pathways. Blood samples (serum) are routinely collected for bio banking both in cases and controls. Patients are followed 30 days after discharge. Personalized risk prediction models will be derived and validated based on advanced statistical models including machine-based learning incorporating a variety of clinical parameters and biomarker signatures (including digitally stored in-hospital data, e.g. imaging, ECG, ventilation parameters). Close cooperation with multiple other national and international COVID-19 cohorts is endorsed. The personalized risk prediction models from the COVIVA study will support clinicians in the most challenging process of limited resource allocation in a timely fashion. In addition, pathophysiological mechanisms and differences in mild and severe variants of COVID-19 as well as in the control group can be extensively studied in a multidisciplinary approach.
The understanding of haemostasis and inflammation cross-talk has gained considerable knowledge during the past decade in the field of arterial and venous thrombosis. Complex and delicately balanced interaction between coagulation and inflammation involve all cellular and humoral components. Elements of the coagulation system such as activated thrombin, fibrinogen or factor Xa may increase inflammation by promoting the production of pro-inflammatory cytokines, chemokines, growth factors and adhesion molecules that lead to a procoagulant state amplifying the pathological process. Recent evidence supports inflammation as a common pathogenic contributor to both arterial and venous thrombosis, giving rise to the concept of inflammation-induced thrombosis. Patients with infection of COVID-19 and severe pneumoniae seem to have higher risk of thromboembolism. Very few data are available regarding the biological disorders of coagulation in these patients. Th purpose of this project is to analyze hemostasis and coagulation of patients with infection of COVID-19 and severe pneumonia.
This study evaluates the effects of the addition of chlorpromazine to the standard therapeutic protocol in COVID-19 patients hospitalized for respiratory symptom management (score 3-5 WHO Ordinal Scale for Clinical Improvement).
The disease caused by the SARS-CoV-2 virus is a viral disease that infects the lungs, producing flu-like symptoms. Elderly infected patients and/or those with co-morbidities may suffer from acute respiratory distress syndrome due to pneumonia (COVID-19 disease). Given the high transmission, this virus has spread in recent months from Wuhan (China) to the whole world, becoming a global emergency pandemic. The lack of curative treatment for this disease justifies the need to carry out clinical trials that provide quality evidence on treatment options. Given the pathophysiology of the disease, which involves an uncontrolled inflammatory response of alveolar cells, a treatment that attenuates the cytokine cascade could be key in rescuing the patient's lung tissue. Mesenchymal cells, due to their immunoregulatory potential and regenerative capacity, can be an effective treatment for patients infected with the SARS-CoV-2 virus. In the present study we propose a therapy with undifferentiated allogeneic mesenchymal cells derived from umbilical cord tissue, a treatment whose safety has already been described in other clinical trials and that shows promising results in pilot studies carried out in China.
