Active clinical trials for "COVID-19"

The objective of this study is to assess the inoculation-related symptoms and long-term effects of COVID-19 vaccines in patients with lung cancer or pulmonary nodules in a real-world setting. The investigators aim to provide high-quality evidence for the COVID-19 vaccines in cancer/pre-cancer patients, and to address their concern about the safety profile of the newly developed vaccines.

The purpose of this study is to assess the use of technology including remote vital sign monitoring in improving quality of patient care, decreasing hospital admissions and re-admissions, decreasing hospital length of stay and decreasing use of personal protective equipment.

This study is a prospective, observational, open, monocentric multisite, pharmacokinetic study of hydroxychloroquine in critically ill patients. The aim of this study is to assess the pharmacokinetic behavior of hydroxychloroquine in COVID-19 critically ill patients treated with crushed hydroxychloroquine tablets (administered enterally using a nasogastric tube).

Months after seemingly recovering from COVID-19, many patients continue to suffer from major long-term effects. Interestingly, the existence of direct link between the severity of the disease in its acute phase and the severity of the long-lasting symptoms is uncertain. We aim at characterizing the long term outcomes in patients hospitalised for COVID-19 including symptoms, medical history, persistent organ damage and neurological and behavioural sequelae.

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.

Background: Coronavirus disease 2019 (COVID-19) is an acute respiratory syndrome. It is caused by the SARS-CoV-2 virus. People with severe COVID-19 infection have a hyper-inflammatory response. Bruton tyrosine kinase (BTK) plays a role in the innate immune system. BTK inhibition can be used to target the innate immune system that appears to contribute to mortality. This could be an effective way to help the inflammatory responses in people with COVID-19. Objective: To learn more about the immunologic mechanisms by which BTK inhibition may decrease hyper-inflammatory responses in people with COVID-19. Eligibility: People ages 18 and older in one of the following groups: They are in the hospital with COVID-19. They will or will not be treated with a BTK inhibitor. They do not have COVID-19. They are or are not in the hospital. They will be treated with a BTK inhibitor for a reason other than COVID-19. Design: Participants will be screened with a review of their demographic and clinical information. Their medical history will be reviewed. If they have COVID-19, their symptoms will be assessed. Participants will give 3-4 blood samples. These may be taken through a vein. They may also be taken through an existing central venous catheter. Participants may give a stool sample. This will be collected by nursing staff. It will be collected using a stool collection vial. Stool collection is optional. Participants samples will be collected over about 7 days. These will be used for research and genetic testing.

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 purpose of the study is to verify the sensibility and accuracy of a rapid detection test for SARS-CoV-2 in breath samples analyzed by the breath detector analyzer TeraSystem, comparing with PCR tests.

This study is a survey of the Moderna COVID-19 vaccine in Japanese people at high risk of developing severe COVID-19 symptoms. The study sponsor will not be involved in how the participants are treated but will provide instructions on how the clinics will record what happens during the study. The main aim of the study is to check for side effects of the Moderna COVID-19 vaccine in this group. This will be from the first vaccination to 28 days after the second vaccination. The number of visits to the clinic will depend on the clinic's standard practice.

To analyze the intubation with severe covid-19 pneumonia, the infection rate of anesthesiologist after intubation, and summarizes the experience of how to avoid the infection of anesthesiologist and ensure the safety of patients with severe covid-19 pneumonia.
