Active clinical trials for "COVID-19"

The next phase of the COVID-19 pandemic is likely to see a surge in an associated chronic cardiopulmonary disease that will challenge health systems. Recovered patients are presenting with persistent dyspnea at the Duke Pulmonary Post-COVID clinic. Evidence is now mounting that recovered patients have significant residual pulmonary disease, while myocardial injury has also been increasingly reported. To optimally care for these patients, Duke Pulmonary study team must comprehensively assess and monitor the changes in cardiopulmonary function and relate the changes to physiologic and quality of life outcomes. The study team will deploy cutting-edge MRI to fully characterize cardiopulmonary function in enrolled 30 subjects (accrual 23 subjects) at time point 60-120 days post recovery and 6-9 months later. Cardiac MRI will assess the myocardial status and right ventricular function, while hyperpolarized 129Xe MRI will provide a 3D assessment of pulmonary ventilation, interstitial barrier integrity, and pulmonary vascular hemodynamics. The overall objective outlined in this study is to demonstrate the feasibility and value of comprehensive longitudinal imaging characterization of cardiopulmonary structure and function in patients recovered from Covid-19.

The investigators will carry out a randomised trial of free face mask distribution in Stovner District, Oslo, Norway. Ten grocery stores will serve as study sites. Over three weeks the stores will be randomised daily to having "corona hosts" outside their entrance, handing out face masks to customers. The investigators will compare the proportion of customers who wear face masks as they enter the store in stores with or without face mask distribution.

The objective is to demonstrate if there is no increase in the risk of Sars-Cov-2 salivary carriage 7 days after a concert in the group participating in the event compared to a non participating group who stayed at home. The hypothesis is that a systematic screening of Sars-Cov-2 within the 3 days before the event allows to control the risk of transmission and prevent cluster of transmission during the concert.

This study evaluates the feasibility of an early occupational therapy (OT) protocol in critical adult patients requiring mechanical ventilation with Covid-19.

This study will target Madison Metropolitan School District (MMSD) school children ages 4-19 and staff who have not had a previous positive COVID-19 test within the past 3 months. It will enroll children and adults for 1-3 days to explore whether serial "at-home" BinaxNOW testing is feasible and non-inferior to "at school" single PCR testing for the evaluation of symptomatic individuals with a negative initial BinaxNOW. It will also explore whether lollipop swabs are more acceptable and perform as well as nasal swabs with polymerase chain reaction (PCR) testing.

Originally, the study was planned to include two parts, i.e., Part A and Part B, however Part B was skipped due to changes in the overall clinical development plan. The conducted Part A was a dose-finding part to investigate the optimal dose, allowing dose adjustments upwards and downwards in younger participants. Doses tested in older participants were chosen based on acceptability of dosing in younger participants.

CORONAVIT is an open-label, phase 3, randomised clinical trial testing whether implementation of a test-and-treat approach to correction of sub-optimal vitamin D status results in reduced risk and/or severity of COVID-19 and other acute respiratory infections.

Electronic-nose had been used to diagnose other infectious lung diseases, such as tuberculosis. Universitas Gadjah Mada has developed an electronic-nose device which is easy-to-use, portable, and can be manufactured at a low price. Here the investigators test the electronic-nose to diagnose COVID-19 in Indonesia.

Corona Virus Disease (COVID-19), spread worldwide and has become an emergency of major international concern. In March 2020, the WHO declared the COVID-19 outbreak a global pandemic. Accurate and fast diagnosis is crucial in managing the pandemic. Current diagnostic approaches raise several difficulties: they are time-consuming, expensive, invasive, and most important lacking high sensitivity. The gold standard diagnostic test for COVID-19, reverse transcription polymerase chain reaction (RT-PCR), is highly dependent on adequate deep sampling of the swab in the naso- and oropharynx. A new diagnostic test that can correctly and rapidly identify infected patients and asymptomatic carriers is urgently required to prevent further virus transmission and thus reduce mortality rates. Aim: This proof-of-principle study aims to investigate if an electronic nose (Aeonose) can distinguish individuals with antibodies from individuals without antibodies against COVID-19 based on analysis of volatile organic compounds (VOCs). Methods: between April and July 2020, persons undergoing RT-PCR and a serology test for COVID-19 were recruited at Maastricht UMC+ for breath analysis. All participants had to breathe through the Aeonose for five consecutive minutes. The VOC pattern in their exhaled breath was then linked to the matching RT-PCR and serological test results.

There is currently no clinically proven specific antiviral agent available for SARS-CoV-2 infection. Supportive treatment, including oxygen therapy, remains the most important management strategy. Since its discovery, lactoferrin and its related peptides are mainly considered to be important non-specific host defense molecules against a broad range of viruses including SARS-CoV, which is closely related to SARS-CoV-2 that causes COVID-19. Lactoferrin has been found to experimentally inhibit viral entry in murine coronavirus, and human coronaviruses hCOV-NL63 and pseudotyped SARS-CoV. Besides reducing viral entry, lactoferrin can also suppress virus replication after the viral entry. Another major aspect of lactoferrin bioactivity relates to its immunomodulatory and anti-inflammatory functions. Current thinking suggests that mortality from COVID-19 is not simply due to viral infection but is a result of a cytokine storm associated with hyper-inflammation leading to acute respiratory distress and subsequent mortality. A cytokine profile in severe COVID-19 cases is characterized by increases in cytokines and acute phase reactants and ferritin. In this regard, lactoferrin was demonstrated to reduce IL-6, TNF a, and downregulate ferritin in experimental settings simulating sepsis. In this study, we aim to study the potential application of lactoferrin against SARS-CoV-2 and propose the possibility of using different doses of supplemental lactoferrin as a potential adjunct treatment for COVID-19.
