Although direct evidence is currently lacking, the high identity between SARS-CoV-1 and SARS-CoV-2 suggests, that the latter viral strain could also infect the Central Nervous System (CNS). Indeed, some cases of SARS-COV2 encephalitis begin to be described and CNS damages are increasingly highlighted in the literature, but still not objectified by imaging and do not allow to explain the entire clinical patterns. We hypothesise that these CNS damages are not always objectified by Magnetic Resonance Imaging (MRI) but could be indirectly observed by a physiological dysfunction of neural conduction in the brainstem. We will explore brainstem disruption through an electrophysiological approach.
The prognosis of patients with severe COVID-19 disease, whose lungs are so severely diseased that they need to be supported by veno-venous ECMO (extracorporeal membrane oxygenation), is difficult to assess so far. Previously published data from studies, case reports and case series describe a very high mortality in this patient collective. The significance of established clinical prognostic cores in this patient population has not been systematically investigated. This is aggravated by the fact that even at very specialized centers only very few patients from this collective are (can be) treated, so that valid investigations are only possible in a multicenter patient collective. In this registry study, all patients diagnosed with COVID-19 and treated with vv-ECMO in the centers participating in the study should be retrospectively examined. The primary aim of the study is to investigate 30-day survival, secondary objectives include the analysis of different clinical scores at the time of ECMO implantation.
Hospitals are recognised to be a major risk for the spread of infections despite the availability of protective measures. Under normal circumstances, staff may acquire and transmit infections, but the health impact of within hospital infection is greatest in vulnerable patients. For the novel coronavirus that causes COVID-19, like recent outbreaks such as the SARS and Ebola virus, the risk of within hospital spread of infection presents an additional, significant health risk to healthcare workers. Infection Prevention and Control (IPC) teams within hospitals engage in practices that minimise the number of infections acquired within hospital. This includes surveillance of infection spread, and proactively leading on training to clinical and other hospital teams. There is now good evidence that genome sequencing of epidemic viruses such as that which causes COVID-19, together with standard IPC, more effectively reduces within hospital infection rates and may help identify the routes of transmission, than just existing IPC practice. It is proposed to evaluate the benefit of genome sequencing in this context, and whether rapid (24-48h) turnaround on the data to IPC teams has an impact on that level of benefit. The study team will ask participating NHS hospitals to collect IPC information as per usual practice for a short time to establish data for comparison. Where patients are confirmed to have a COVID-19 infection thought to have been transmitted within hospital, their samples will be sequenced with data fed back to hospital teams during the intervention phase. A final phase without the intervention may take place for additional information on standard IPC practice when the COVID-19 outbreak is at a low level nationwide.
Designed as a multi-center, randomized, double-blind, placebo-controlled study to assess the efficacy and safety of EIDD-2801 on SARS-CoV-2 Virus Shedding in Newly Hospitalized Adults with polymerase chain reaction (PCR)-Confirmed COVID-19.
This clinical study will assess the safety, reactogenicity, and immunogenicity of 2 dose levels of mRNA-1273 Severe Acute Respiratory Syndrome coronavirus (SARS-COV-2) vaccine in adults 18 years of age or older.
The purpose of this study is to learn more about infection with and recovery from the virus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Some people know this virus by the name "coronavirus." It can cause the disease called COVID-19. The information gained from the study will be used to help develop better tests for SARS-CoV-2 infection and COVID-19 disease and may help in developing future vaccines and treatments by allowing researchers to determine the difference between the body's immune response to natural SARS-CoV-2 infection and immunization with a SARS-CoV-2 vaccine.
This study is designed to evaluate a potential mechanism by which a hyperactive immune response may contribute to death from SARS-CoV-2; by an excessive neutrophil-mediated deposition of cell-free DNA in neutrophil extracellular traps (NET). Excessive amounts of NETs can increase rigidity of mucus, clog airways, and be agents for the development of acute respiratory distress (Narasaraju et al., Am J Pathol. 2011). Many aspects of this pathway have been observed in severe SARS-CoV-2 (Zhang et al., Respiratory research. 2020). Dornase alfa (DNAse I; Pulmozyme (Genentech) is a nebulized drug that works by degrading cell-free DNA and thus promoting airway clearance and recovery. The investigators hypothesize that by thinning mucus and degrading these NETs further lung damage may be prevented and a reduction in time to recovery may occur. The two aims of the study are to see if inhaled/nebulized dornase alfa will improve clinical outcome measures in SARS-CoV-2 related acute respiratory distress syndrome (ARDS) and to see if dornase alfa reduces the amount of bronchoalveolar lavage and blood markers of NET activity. The study will recruit patients who are on mechanical ventilation for respiratory failure related to SARS-CoV-2 positive infection and have ARDS based upon Berlin criteria. The investigators aim to recruit 10-20 patients for this study.
Natural products with immunomodulation and antiviral activity showed a promising improvement in the outcomes of some viral infectious diseases both in preclinical and primitive clinical studies. The aim of this study is to utilize Saudi FDA licensed Nigella sativa (NS) seed oil towards improving disease outcomes in adult patients diagnosed with mild COVID-19. The study will be a prospective, open-label, non-randomized controlled pilot trial. Patients will be supplemented (add-on) with one capsule of black seed oil twice daily for 10 days. The primary outcome will be the proportion of patients who clinically recovered on day 14. The secondary outcomes will be clinical parameters and routine laboratory tests. If encouraging outcomes occurred, NS supplementation may be recommended as an add-on to standard care protocol to enhance the recovery from COVID-19 disease in the current emerging situation.
The aim of the SARS-CoV-2-CZ-Preval study is to quantify the prevalence of individuals with a history of SARS-CoV-2 coronavirus infection in the Czech population, except for those diagnosed with COVID-19 by methods based on direct detection of SARS-CoV- 2, including individuals with a subclinical course of the disease.
