Active clinical trials for "COVID-19"

The objective of this research is to build a collection of non-invasive retinal imaging (OCT and OCTA) in order to investigate the incidence and impact of retinal damage in patients who have or have had COVID-19.

Coronavirus Disease 2019 (COVID-19) is a newly emerged disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The COVID-19 pandemic is having a large impact on the mental and physical health of patients, yet data on the quality of life of post-COVID-19 patients is lacking. There are currently no post-COVID-19 specific measures for quality of life, particularly none which include the views of post-COVID-19 patients themselves. This observational study will recruit participants to contribute their preferences to the creation of a post-COVID-19 specific patient-reported measure on post-COVID-19 quality of life. Participants will be split into three groups: those who were not hospitalised; those who were hospitalised but not in intensive care units; and those who were hospitalised and in intensive care units. The creation of this measure will form phase 1 of the study, with 30-60 participants (10-20 in each group above) recruited to complete online surveys to find out their preferences of areas of life to include in such a measure. This will involve 3 online surveys, 1) to ask which areas of life they feel are impacted and how; 2) to find consensus about the areas to be included; 3) to weight the relevance of these areas in relation to each other. In phase 2 recruitment will open to additional participants and all participants will be asked to complete the finalised post-COVID-19 quality of life measure once a month for 12 months, aiming for a minimum of 100 participants at this stage. All participants will also be asked to complete a demographic questionnaire to inform the analysis of the data.

The disease promoted by coronavirus (COVID-19) is caused by Severe Acute Respiratory Syndrome (SARS) caused by Coronavirus type 2 (CoV2), being the first cases identified in December 2019 in China after exposure to the animal market in Wuhan city, China. From the first case to the present day, the COVID-19 epidemic has been identified in 185 countries, with the notification of 2,666,154 cases and 186,144 deaths. In Brazil, more than 45,757 cases and 2,906 confirmed deaths by COVID-19 have been confirmed (Visualized on Apr 23 2020). In our country, to date, testing for COVID-19 occurs only in severe cases and few centers offer the service to health care workers, a population at high risk of infection. BCG is a vaccine produced from a live attenuated strain derived from a Mycobacterium bovis isolate and is widely used worldwide as a tuberculosis (TB) vaccine, but there are studies demonstrating non-specific immunotherapeutic mechanisms of this vaccine that signal a possible relationship with the lowest morbidity and mortality associated with COVID-19 infections worldwide. The present study aims to analyze the role of BCG in the prevention of SARS-CoV-2 infection and also in the occurrence of severe forms of COVID-19 in addition to evaluating the immune response mediated by this vaccine in voluntary health care workers.

Coronavirus disease 2019 (COVID-19) is a highly infectious pandemic disease caused by SARS-CoV-2 virus. Central Nervous System (CNS) complications associated with COVID-19 might be secondary sequelae due to exuberant systemic innate-mediated hyper-inflammation, which may impair neurovascular endothelial function, disrupt blood brain barrier (BBB), activates CNS innate immune signaling pathways, and induces parainfectious autoimmunity, potentially contributing to the CNS manifestations. Although the predominant clinical manifestation of SARS-CoV-2 is characterized by dyspnea, unremitting fever and hypoxemic respiratory failure, neurologic manifestations do occur in most hospitalized SARS-CoV-2 patients and include non-specific encephalopathy, psychosis, meningitis/encephalitis, myelitis, cerebrovascular events, Guillain-Barre' syndrome, and cranial or peripheral neuropathies, such as anosmia and ageusia. To date, data about primary CNS involvement due to neurotropism and direct neuroinvasion are still lacking.

There is an unmet need to evaluate the impact of sub-clinical/mild COVID19 disease in the outpatient setting on prevalent and incident renal injury, as this data is currently unavailable. To capture the diversity of race/ethnic risk and COVID19 related municipal shelter-in-place guidance, the investigators will enroll COVID19-negative and COVID19-positive samples balanced by race/ethnicity from 3 different states, California, Michigan, and Illinois. Study endpoints will be assayed from urine samples mailed to the study team at 2, 6, and 12 months after their date of PCR test, with no requirement for these individuals to leave their homes to participate.

This nested project of the Swiss Multiple Sclerosis Cohort (SMSC) is to assess the severity of COVID-19 and the magnitude of antibody response after infection with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in patients already treated or not with various immunotherapies for multiple sclerosis followed in the framework of the SMSC.

Acute Respiratory Distress Syndrome (ARDS) reflects the hallmark of the critical course of coronavirus (COVID19). The investigators have recently shown that Exhaled Breath Particles (EBP) measured as particle flow rate (PFR) from the airways could be used as a noninvasive real-time early detection method for primary graft dysfunction (which bears a pathophysiological resemblance to ARDS) in lung transplant patients. The investigators have also previously demonstrated the utility of PFR in early detection and monitoring of ARDS in a large animal model. PFR has been shown to be elevated prior to the cytokine storm which classically occurs in ARDS. Early detection of ALI and ARDS is intimately linked to a patient's chance of survival as early treatment consisting of the preparation for intensive care, prone positioning and protective mechanical ventilation can be implemented early in the process. In the present study the investigators aim to use real-time PFR as an early detector for COVID19-induced ARDS. The investigators will also collect EBPs onto a membrane for subsequent molecular analysis. Previous studies have shown that most of those proteins found in bronchoalveolar lavage (BAL) can also be detected in EBPs deposited on membranes. The investigators therefore also aim to be able to diagnose COVID19 by analyzing EBPs using Polymerase Chain Reaction (PCR) with the same specificity as PCR from BAL, with the added benefit of being able to identify protein biomarkers for early detection of ARDS.

COVID-19 has become a global problem. There is an urgent need to improve the diagnosis and screening of patients and healthcare workers for COVID-19 in the UK. Mask based sampling is a method of detecting SARS-COV-2 (the virus responsible for COVID-19) in the breath of suspected COVID-19 patients or healthcare workers in the mask that they would wear in hospital. The investigators have previously demonstrated the utility of this method in other respiratory infections, such as tuberculosis. This project aims to investigate the utility of mask-based sampling is a tool for the diagnosis and quantification of COVID-19 in breath and the implications in a healthcare setting using three cohorts of participants. Initially we will compare the amount of COVID-19 detected by mask sampling compared with standard nasopharyngeal swab, which is the current gold standard test, in patients who present to hospital with COVID-19 symptoms. We will address the length of time COVID-19 is breathed out by people affected by the virus and the how infectious the virus is over time in a cohort of symptomatic healthcare workers who are isolating at home. This will allow us to understand how long someone stays infectious for and may have the potential to inform public health measures, for instance when healthcare workers can return to work or duration of isolation. Finally we will investigate asymptomatic carriage of COVID-19 by different healthcare workers in different areas of the hospital during a screening study. This will allow us to understand the extent of infection amongst healthcare workers and allow us to address hospital acquired transmission.

This study investigates the impact of the COVID-19 pandemic on the psychosocial health of employees of MD Anderson Cancer Center. Epidemics have been shown to promote psychological stress among medical staff in high risk areas, which may lead to mental health problems. Assessing how the pandemic is affecting employees may allow for more comprehensive actions to be taken to protect the mental health of employees.

Sex and gender matter to health equity, especially in a pandemic. Sex (a biological attribute) and gender (a social construct) may influence an individual's susceptibility, vulnerability and exposure to infectious disease. In previous coronavirus epidemics (SARS and MERS), male sex was associated with worse outcomes. Both immune and the hemostatic response display ample sexual dimorphism. The primary aim of the study is to determine whether sex differences in biomarkers of platelet and immune function, gut microbiome, clinical characteristics, therapy, clinical cost sensitive outcomes (i.e. in-hospital transition of care, case severity, and mortality due to COVID-19) exist in patients affected by COVID-19.
