Active clinical trials for "Coronavirus Infections"

It has been suggested that ibuprofen might be associated with more severe cases of coronavirus infections, based on the observation that severe COVID cases had been exposed to ibuprofen, resulting in a warning by the French authorities. This was attributed to: a suggestion that ibuprofen might upregulate ACE-2 thereby increasing the entrance of COVID-19 into the cells, an analogy with bacterial soft-tissue infections where more severe infections on NSAIDs are attributed to an immune-depressive action of NSAIDs, or to belated treatment because of initial symptom suppression, fever is a natural response to viral infection, and reduces virus activity: antipyretic activity might reduce natural defenses against viruses. However fever reduction in critically ill patients had no effect on survival. However, these assertions are unclear: upregulation of ACEII would increase the risk of infection, not necessarily its severity, and would only apply to the use of NSAIDs before the infection, i.e. chronic exposure. It would be irrelevant to the infection once the patients are infected, i.e., to symptomatic treatment of COVID-19 infection. Anti-inflammatory effect masking the early symptoms of bacterial infections resulting in later antibiotic or other treatment is not applicable: there is no treatment of the virus that might be affected by masking symptoms. Antipyretic effect increasing the risk or the severity of infection would apply equally to all antipyretic agents including paracetamol, which share the same mechanism of action for fever reduction. EMA remains prudent about this assertion In addition, excess reliance on paracetamol while discouraging the use of ibuprofen might increase the risk of hepatic injury from paracetamol overdose. Paracetamol is the prime drug associated with liver injury and transplantation, in voluntary and inadvertent overdose or even at normal doses. This might be increased by COVID-related liver function alterations. It is therefore proposed to conduct a case-control study in a cohort of patients admitted to hospital in France with COVID-19 infection.

Adaptive Biotechnologies has developed a clinical test called T-Detect COVID Test that can identify a T-cell response to the SARS-CoV-2 virus, indicating recent or prior infection This study aims to evaluate the potential cross-reactivity of the T-Detect COVID test in participants presenting with viral upper respiratory tract infections within the assay's intended use population and testing positive for seasonal coronavirus.

The investigators aim to do serosurvey of healthcare-personnel who had participated in treatment of confirmed patients of Middle-East respiratory syndrome. The investigators collected the base-line (pre-exposure) serum of healthcare-personnel in a few centers, and will collect the post-exposure serum from about 25-30 centers in which confirmed MERS patients had been treated. The investigators will deduct the seroprevalence of MERS-CoV IgG among the healthy healthcare-personnel, and calculate the sero-conversion rate if possible. The investigators will subdivided the seroprevalence according to the degree of exposure and preparedness of personal protective equipment.

This study aim to evaluate the immune response of negative patients during a COVID-19 outbreak. Patients are serially tested with a VivaDiag ™ COVID-19 lgM / IgG Rapid Test to evaluate the immune response in negative patients and the reliability of the test in those patients who develop clinical signs of COVID-19 during the trial.

Observational, retrospective data collection and prospective IgG analysis, and multicenter study. The main objective of the study is th description of the characteristics and evolution of patients with lung cancer who have acquired COVID-19 infection. For the identification of patients who contract COVID-19 infection, the IgG+ blood test by ELISA method will be used.

The search for novel therapies to address the ongoing coronavirus (COVID-19) pandemic is ongoing. No proven therapies have been identified to prevent progression of the virus. Preliminary data suggest that inhaled nitric oxide (iNO) could have benefit in preventing viral progression and reducing reliance on supplemental oxygen and ventilator support. Expanded access allows for iNO to be delivered via the portable INOpulse delivery system for the treatment of COVID-19.

This a double-blind, randomized, placebo-controlled clinical trial to determine if primary prophylaxis with hydroxychloroquine in healthcare workers reduces symptomatic COVID-19 infection. Healthcare workers will be randomized at a 1:1 allocation between intervention and placebo arms and followed for 12 weeks. This study will enroll up to 1,700 participates in Lafayette, Louisiana. The primary outcome will number of symptomatic COVID-19 infections. Secondary endpoints included number of days healthcare workers are absent from work and rate of severe infection.

The "COVIDOR" epidemiological study. Our study would be the first at the community level in Orleans Métropole, aiming to determine the link between a positive IgM level on the serological test and a healthy carrier of covid-19 in agents in contact with the public. It would provide epidemiological surveillance of anti-covid-19 immunity in the community

SARS-CoV-2 has now crossed the 1 million number of cases and tens of thousands of deaths. It´s R0 has been calculated between 2 and 5.7 solely based on clinical symptoms but it is estimated to likely be higher. Serologic evidence of infection has not been analyzed.

This study aims to design a Convolutional Neural Network (CNN) and apply an attention model to help differentiate pneumonia due to Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), pneumonia due to other viruses/bacteria, and normal chest x-ray (CXR) in clinical practice. A bank of digital chest images from a high-complexity health facility in Cali, Colombia, was used.
