Filter by:The purpose of the investigators is to study the psychological impact of the COVID-19 lockdown on the members of the Ville Evrard Hospital staff and their close relatives, and to identify potential lockdown conditions that could increase anxiety, anger and depressive symptoms in this population.
In the SAVE study patients with lower respiratory tract infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at high risk for progression to serious respiratory failure will be detected using the suPAR biomarker. They will begin early treatment with anakinra in the effort to prevent progression in serious respiratory failure.
The aim of this study is to evaluate the efficacy of pulmonary physiotherapy on respiratory functions in hospitalized patients with Novel Coronavirus 2019 pneumonia. Patients will be randomized into 1) intervention group: receiving pulmonary physiotherapy technique to improve pulmonary function and walking training or 2) control group: Usual medical care. Patients in both groups will receive therapeutic incentive spirometer. Various outcome measurements of pulmonary functions will be evaluated before and after of interventions. Mortality rate, hospitalization duration and re-admission will be followed until one month after end of intervention. Also, patient's quality of life will be measured after one month.
The present Diagnostic Accuracy study aims at experimentally validating the use of a rapid salivary test to detect SARS-CoV-2 infection in both symptomatic and asymptomatic individuals as a preliminary approach to a mass screening program. The study is based on a consecutive recruitment of both patients showing symptoms probably associated with COVID-19 (i.e., cough, dyspnea, fever) and asymptomatic patients with a low risk phenotype. The expected number of recruited individuals is 100. The experimental test is a prototype of salivary test based on the Lateral Flow Immunoassay technique and is able to detect the presence of SARS-CoV-2 in saliva, especially the Spike protein (S). The comparison is represented by the nasopharyngeal swab, the gold standard of COVID-19 diagnosis. Patients will undergo both salivary immunoassay and nasopharyngeal swab, thus the outcome assessors are blinded, since the results of the rRT-PCR analysis require at least 6 hours before being available. The main outcomes are sensibility and specificity of the rapid salivary test, when compared with the gold standard (nasopharyngeal swab).
Increased D-dimers at admission of COVID-19 infected patients entering hospital due to a severe disease is a risk factor for death. Understanding this acquired coagulopathy is a prerequisite before specific interventional studies. The study investigators aim to apply a normalized and automated thrombin generation test (TGT), developed for testing the thrombotic risk (triggered by 5 pM Tissue Factor, with a purified thrombomodulin (TM) challenge) and to study its association with survival.
Three hundred healthcare workers with mild symptoms for Covid-19 will be followed during three months. Each two weeks, serological tests will be performed. Re-infection will be monitored by saliva-swabs.
Doctors, nurses and staff members of ear-nose and throat (ENT) departments are at high risk due to aerosol-inducing diagnostic procedures and surgery during the COVID-19 epidemic. Reports from China, Spain, Italy and England report of fatal cases among ENT specialists. With a concurrent lack of personal protection, it is of paramount importance to identify patients and healthcare workers at an early stage to prevent a COVID-19 outbreak in the department. A baseline study of all healthcare workers has been performed. Follow-up will be accomplished by interval testing, antibody measurements and REDcap Covid-19 questionnaires. All patients at risk of carrying SARS-CoV-2, or who are candidates for high-risk airway surgery will be tested. Infection control measures at the department will be implemented progressively according to the real-time surveillance results from both patients and healthcare workers.
Plasma therapy using convalescent plasma has been shown to be effective in severe acute respiratory syndrome, Ebola virus infection and in H1N1 influenza. More recently there has been a report of the use of convalescent plasma in the treatment of 5 ventilated COVID-19 patients with the suggestion of expedited recovery as the patients improved 1 week after the transfusion. However, this was not a clinical trial and the patients were on other antiviral medication.; therefore, there is a need to undertake such a trial to see if deploying plasma with SARS-CoV-2 neutralizing antibody has utility in managing patients infected with COVID-19 in respiratory distress. The objective of this pilot study is to compare plasma therapy using convalescent plasma with antibody against SARS-CoV-2 to usual supportive therapy in COVID-19 patients with pneumonia and hypoxia, and to determine if the clinical course is improved. The difference between groups will allow an effect size to be determined for a definitive clinical trial.
Inflammation and abnormalities in laboratory coagulation tests are inseparably tied. For example, coagulation abnormalities are nearly universal in septic patients. Coagulation disorders have also been reported in many patients with severe courses of Coronavirus disease 2019 (Covid-19). But it is difficult to assess these changes. Global coagulation tests have been shown to incorrectly assess in vivo coagulation in patients admitted to intensive care units. But other tests are available. Thrombin generation assay (TGA) is a laboratory test which allows the assessment of an individual's potential to generate thrombin. But also in conventional TGA the protein C system is hardly activated because of the absence of endothelial cells (containing natural thrombomodulin) in the plasma sample. Therefore the investigators add recombinant human thrombomodulin to a conventional TGA. Thereby the investigators hope to be able to depict in vivo coagulation more closely than global coagulation tests do.
In late 2019, a new coronavirus emerged in Wuhan Province, China, causing lung complications similar to those produced by the SARS coronavirus in the 2002-2003 epidemic. This new disease was named COVID-19 and the causative virus SARS-CoV-2. The SARS-CoV-2 virus, enters the airway and binds, by means of the S protein on its surface to the membrane protein ACE2 in type 2 alveolar cells. The S protein-ACE2 complex is internalized by endocytosis leading to a partial decrease or total loss of the enzymatic function ACE2 in the alveolar cells and in turn increasing the tissue concentration of pro-inflammatory angiotensin II by decreasing its degradation and reducing the concentration of its physiological antagonist angiotensin 1-7. High levels of angiotensin II on the lung interstitium can promote apoptosis initiating an inflammatory process with release of proinflammatory cytokines, establishing a self-powered cascade, leading eventually to ARDS. It has recently been proposed the tentative use of agents such as losartan and telmisartan as alternative options for treating COVID-19 patients prior to development of ARDS. The present study is an open-label randomized phase II clinical trial for the evaluation of telmisartan in COVID-19 patients. Briefly, patients with confirmed diagnosis of SARS-CoV-2, will be randomized to receive 80 mg/12h of telmisartan plus standard care or standard care alone aand will be monitored for development of systemic inflammation and acute respiratory distress syndrome. Other variables regarding lung function and cardiovascular function will also be evaluated.
