Active clinical trials for "COVID-19"

The SARS-CoV-2 epidemic was declared as a global pandemic by the WHO on March 12, 2020. France is affected with approximately 120,000 biologically confirmed cases, as of April 30, 2020, a figure probably very underestimated. Its distribution in different populations, in particular immunocompromised, has not yet been measured. The in vitro efficacy of lopinavir coupled with ritonavir, an HIV protease inhibitor, on SARS-CoV, responsible for SARS has been discussed and this therapeutic combination is currently being evaluated in patients infected with COVID-19. The possible protective role of treatment with Lopinavir / ritonavir or another HIV protease inhibitor has not been studied. In addition, patients receiving HIV pre-exposure prophylaxis (PrEP) share certain epidemiological and behavioral characteristics with HIV-infected patients. The objective was to carry out an epidemiological study aimed at determining the attack rate of COVID-19 infection in patients infected with HIV and or on PrEP and to analyze this attack rate according to the characteristics of these 2 populations and in particular the existence or not of an antiretroviral treatment comprising Lopinavir / Ritonavir or another inhibitor of the HIV protease. Cross-referencing of Virology Laboratory data (positive or negative screening) and clinical-biological data can be easily carried out using a unique identification number in the 2 software programs and will allow an almost exhaustive epidemiological analysis in 2 well identified populations.

The aim of this study is to investigate the levels of trauma and mental symptoms (i.e., depression and anxiety) among health workers and public service providers during the strict social distancing government-initiated non-pharmacological interventions (NPI's) related to the COVID-19 pandemic. The study also aims to investigate predictors of trauma-symptoms.

This study proposes to compare the effectiveness of two different levels of PPE in protecting front-line health care workers from self-contamination with droplets and aerosolized particles during a simulated endotracheal intubation, an aerosol-generating medical procedure.

Reports of acute pulmonary embolism (APE) associated with COVID-19 have emerged in the literature. For example, Chen et al. described 25 pulmonary CT angiograms examinations from 1008 COVID-19 patients; 10 were positive for pulmonary embolism mostly as segmental or sub-segmental APE. Case reports of APE in Covid-19 patients have been published. Cui et al. found an incidence of deep venous thrombosis in intensive care unit (ICU) patients with severe Covid-19 pneumonia near to 25% (20/81), however without any correlation with potential APE. Despite these initial reports, it is not clear whether APE is more frequent in Covid-19 patients or if the association is just random. In favor of the former, D-dimer levels have been reported as elevated in patients with Covid-19 by two studies, and it has been suggested an independent association between the severity of the disease and the level of D-dimer. Finally, Tang et al. showed that anticoagulant therapy is associated with a decreased mortality at Day-28 in severe Covid-19 patients, in favor of a possible associated coagulopathy. The purpose of this study is to describe the rate of pulmonary embolus in patients classified as COVID-19 infection and who underwent chest CT angiography. The purpose of this study is to describe the rate of pulmonary embolus in patients classified as COVID-19 infection and who underwent chest CT angiography.

Background: Early evidence in the COVID-19 pandemic suggests that smokers are at a higher risk of having severe effects or dying from the disease. Smoking causes changes in immune cells. Researchers think this may be the reason why smokers are more likely to have severe effects from COVID-19. Researchers want to better understand the interaction between smoking history, the immune system, and COVID-19. Objective: To better understand how COVID-19 affects smokers and non-smokers immune systems before and after being infected with the virus. Eligibility: Healthy people ages 30-55 who are a smokers or non-smokers who may potentially contract COVID-19 Design: Participants will be screened over the phone. They will answer questions about their demographics, medical history, medications, and smoking status. Participants will have up to 6 monthly visits. At the first visit, participants will have blood tests. Blood will be drawn through a needle in an arm vein. They will provide a saliva sample in a container and have a cheek swab. The participant will also have a nasal swab to see if they currently have COVID-19. Their height and weight will be taken. They will complete questionnaires about their medical history and smoking status. Participants will then have monthly visits. They will have blood draws to test for COVID-19 antibodies. They will provide a saliva sample in a container and have a cheek swab. The participant will also have a nasal swab to see if they currently have COVID-19. These visits will occur 4 times or until they have a positive antibody result. Participants will have a final visit. They will have blood tests. They will provide a saliva sample in a container and have a cheek swab. The participant will also have a nasal swab to see if they currently have COVID-19. If at any time participants test positive for a COVID-19, they will be rescheduled 14 days or more after they no longer have symptoms....

Dentist exposed to coronavirus (COVID-19) may not have adequate access to personal protective equipment (PPE), safety procedures, and diagnostic protocols. Our objective will be to evaluate the reality and perceptions about personal safety among dentist in Egypt

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.

Chilblains (inflammatory lesion of the feet or hands) have been reported with an unusual frequency during the confinement period, most commonly in children, teenagers and young adults. The aim of the ECCES study is to find out whether these manifestations of chilblains can be linked to the SARS-CoV-2 coronavirus. For this, an epidemiologic study will compare two types of family (or more precisely people who were confined together in March-April-May): "case family" in which at least one of the members had chilblains "comparator family" in which none of the members had chilblains Environment (home lockdown) of the two types of family will be analyzed. Each member of the "family" will be suggested doing a serological test.

Hydroxychloroquine and azithromycin have been proposed as treatment of COVID-19 patients, but few reports have assessed this combination therapy in critically ill COVID-19 patients. Many raised concerns regarding the potential cardiac toxicity of this association. The purpose of this monocenter retrospective observational study is to evaluate the safety of a short term treatment with hydroxychloroquine and azithromycin in critically ill patients admitted in ICU for severe COVID-19 with respiratory failure. The main objective is to assess the incidence of severe cardiac arrhythmia e.g torsade de pointes and cardiac arrest or sudden death, during the treatment period.

The study is to investigate the antibody response in the blood and saliva of people with a known COVID-19 infection in the canton of Baselland.
