Filter by:Researchers know that the virus that causes COVID-19 has been found in the saliva (spit) of individuals who exhibit signs of the disease. Investigators would like to test the ability of three mouthwashes to reduce the levels of this virus in participants' mouths. Investigators will ask participants to use a liquid to swish around in the mouth for 30 seconds and spit it into a collection cup. Investigators will also collect spit from participants before and after participants use the mouthwash. Although participants will have no direct benefits from the study, investigators will gain a wealth of information that would benefit patients who are at risk for COVID-19.
One hundred patients hospitalized and in need of oxygen treatment due to Covid-19 should be randomized and 50% treated with 200 ml convalescent plasma x 3 and 50% given ordinary treatment. Primary outcome is number of days the patients need oxygen within 28 days from inclusion. Secondary outcome is number of days in hospital, number of days in respirator and mortality. Side effects of treatment is monitored.
Longitudinal prospective study in pregnant women withpositive serology or PCR for SARS-CoV-2 and indicationinvasive technique (amniocentesis or chorionic biopsy) that has the objective to evaluate the possible vertical transmission of SARS-CoV-2in the amniotic fluid or chorionic villi of pregnant women affected by coronavirus in the different periods of gestation.
This study is meant to assess the lung mechanics in SARS-CoV-2 induced acute respiratory failure. A precise characterisation of lung mechanics and heart-lung-interactions might allow a better understanding of SARS-CoV-2 induced acute respiratory failure and thus lead to better mechanical ventilation strategies. This monocentric, observational study of critically ill COVID-19 patients in the ICU, will employ impedance tomography, right-heart catheterization, oesophageal pressure measurements, indirect calorimetry as well as classic mechanical ventilation parameters to characterise the mechanical characteristics of the lung as well as the heart-lung interactions in SARS-CoV-2 induced acute respiratory failure.
Phase 1: 25 patients with a PCR-based diagnosis of Covid-19 will be be included to give 500 microliters of saliva and a 3 ml sample of blood for proteomic analysis; a drop of blood will also be put in a device connected to a silica matrix to perform spectrometric analyses. 25 patients with a non-Covid-19 respiratory infection will be included for the same samples. The proteomic analyses will be performed from classicaly draught blood, blood drop on silica, and saliva, to search for discriminating profiles between Covid-19 and non-Covid-19. Phase 2: 150 patients with a suspected Covid-19 will be included at the same time than the Covid-19PCR is performed ; they will have a sample of saliva and of a drop of blood for proteomic analysis, whose results will be matched with PCR results.
Abstract Title: Randomized,open-label, controlled trial to evaluate efficacy and safety of a highly selective semipermeable membrane (AN69-Oxiris) in comparison with a selective semipermeable membrane ( standard AN69) in COVID-19 associated acute kidney injury: oXAKI-COV study Rationale: Acute kidney injury (AKI) in critically ill mechanically ventilated patients with COVID-19 disease, is present in up to 30% of this group and more than 50% of them will need renal replacement therapy in the form of continuous renal replacement therapy (CRRT). Acute kidney injury in this context seems to be a marker of multiorgan dysfunction and it produces increased mortality in this population. There is a vast amount of mechanisms that lead to AKI in critically ill patients with COVID-19; however, the cytokine storm could be the strongest mechanism implicated in AKI development in individuals with continuous renal replacement therapy requirements. Therefore, blocking or reducing the cytokine storm is thought to be a therapeutic target. Highly selective semipermeable membranes (AN69-Oxiris) have been shown able to adsorb endotoxins and to eliminate inflammatory cytokines, thus representing a valuable therapeutic option in this infection. Objective: To demonstrate clinical efficacy of AN69-Oxiris membrane to reach a stable MAP, with less vasopressor dosing (at least 0.1 micrograms/kg/min) after 72h of treatment, compared to a conventional membrane (standard AN69) in critically ill patients with AKI, COVID-19 infection and requirement of continuous renal replacement therapy. Study design: Randomized,open-label, controlled trial in critically ill patients with suspected or confirmed COVID-19 disease, AKI, and criteria for continuous renal replacement therapy initiation admitted in any of the two participating institutions. Patients meeting inclusion criteria will be randomized to receive CRRT with AN69-Oxiris membrane or standard AN69 membrane during a 72h period.
Background: People who are recovering from COVID-19 may continue to have problems that affect their daily life. For instance, they might feel overly tired. Researchers want to learn if exercise can help people recover after COVID-19 infection. Objective: To study if participation in a rehabilitation exercise program can help people recovering from COVID-19. Eligibility: Adults ages 18-80 with a lab-confirmed SARS-CoV2 infection (the virus that causes COVID-19), and are still having some symptoms. Design: Participants will have a medical history and physical exam. They will give blood and urine samples. They will have tests to measure heart and lung function. Their blood vessels will be assessed. Participants will have a computed tomography scan of the body. They will have an ultrasound of the muscles in their arms, legs, and chest. Participants will take a 6-minute walk test. They will take other balance and movement tests. Participants will walk on a treadmill while hooked up to a monitor. Then they will be interviewed. It will be audio-recorded. Participants will complete surveys about their symptoms and daily activities. Participants will take a smell test. For this, they will identify different smells. They will also have memory, attention, and mental functioning tests. Participants will wear an activity monitor on their wrist 24 hours a day. They will exercise 3 times a week for 10 weeks by moving vigorously on a track or treadmill for 30 minutes. They will attend education classes once a week for 10 weeks. Participants will be contacted by phone or email every 3 months for 1 year after they complete the exercise part of the study. They will wear an activity monitor for up to 2 weeks.
The Investigators propose a multi-center, observational, longitudinal, cohort study of the serology and wellness of HCWs over a year of the COVID-19 pandemic.
Coronavirus disease-2019 (COVID-19), a viral respiratory illness caused by the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), has been associated with the occurrence of cardiovascular adverse events including acute myocardial injury, acute heart failure, cardiac arrhythmias, and thromboembolic disease. These complications represent an important issue in COVID-19 patients accounting for the increased morbidity and mortality of this syndrome. According to a scoping review, venous thromboembolism and stroke occurred in approximately 20% and 3% of patients, respectively, with higher frequency observed in severely ill patients admitted to intensive care units. Despite the use of pharmacological thromboprophylaxis, the thrombotic risk still remained elevated in severe COVID-19 patients, and the optimal doses and timing of anticoagulation are not yet defined. The pathogenesis of COVID-19 associated thrombosis recognizes a prominent role of endothelial damage induced by both direct viral injury and an excessive and aberrant hyper-inflammatory host immune response associated to an increase in infection-related cytokines and chemokines. The occurrence of a hypercoagulable state in COVID-19 patients associated to a profound endothelial cell activation/dysfunction can result in the pathological phenomenon of immunothrombosis. In this study, in a prospective cohort of consecutive COVID-19 hospitalized patients, an extensive characterization of the hemostatic alterations were performed, in order to: 1) clarify mechanisms underlying the coagulopathy in these patients; 2) how and to what extent the concomitant infection with SARS-CoV-2 affect this coagulopathy; and 3) identify biomarkers potentially predictive of disease outcome (i.e. any thrombotic recurrence and death).
SARS-CoV-2, one of a family of human coronaviruses, was initially identified in December 2019 in Wuhan city. This new coronavirus causes a disease that has now been named COVID-19. The virus has subsequently spread throughout the world and was declared a pandemic by the World Health Organisation on 11th March 2020. As of April 1, 2020, there are 874.081 numbers of confirmed cases with 43.290 fatalities. There is no approved therapy for COVID-19 and the current standard of care is supportive treatment. Key markers implying a fatal outcome are acute respiratory distress syndrome (ARDS)-like disease with pronounced dyspnea, hypoxia and radiological changes in the lung. Senicapoc improves oxygenation and reduces fluid retention, inflammation, and bleeding in the lungs of mice with ARDS-like disease. In cells, there is an antiviral effect of senicapoc.
