Active clinical trials for "COVID-19"

The objective of the study is to estimate the frequency of cardiac arrhythmias and characterize the mode of death in patients with coronavirus disease (SARS-CoV-2; COVID-19). The study will also evaluate the long term cardiac outcomes in patients previously diagnosed with COVID-19. This is a single-center, retrospective/ prospective registry enrolling all COVID-19 positive patients at Mount Sinai Hospital. Cohort 1: Retrospective chart review: Patients who have been diagnosed with COVID-19 infection at Mount Sinai Hospital will be included. A cohort of 1000 influenza patients will also be evaluated for purpose of comparison. Cohort 2: Prospective data collection of 100 patients who: Were hospitalized for COVID-19 and who had an abnormal echocardiogram during hospitalization. A matched cohort (for age, gender, troponin level, and days since hospital discharge) who did not have abnormalities on their echocardiograms (or who did not undergo echocardiogram) to ascertain that in this unusual disease, subjects did not develop echo abnormalities following hospital discharge.

COVID-19 pandemic has developed worldwide in less than 4 months. While most patients have a mild or uncomplicated disease (80%), approximately 15% need hospital care and 5% intensive care. Severe cases are characterized by pulmonary involvement which may progress to acute respiratory distress syndrome (ARDS). Early identification of patients who are likely to get worse is therefore a major issue. While, chest X-ray has poor diagnostic performances, pulmonary computed tomography (CT scan) seems very sensitive (97%) and quite specific of COVID-19. Sub-pleural bilateral ground-glass pattern can precede the positivity of RT-PCR for SARS-CoV-2. CT scan is now considered as the best imaging test to assess COVID-19 patients and is recommended as first-line diagnosis tool by the French Society of Radiology (SFR). However, performing CT scan in all or many patients with suspected COVID-19 may result in radiology department overload, especially, taking into account bio-cleaning between patients. Moreover, CT scan may lead to adverse effects including induced cancer due to the cumulative diagnostic irradiation. Chest ultrasonography may be an alternative to CT scan. It is a simple, non-invasive, non-irradiating, inexpensive and available at the point of care (POCUS). Most of emergency physicians and many other specialists (pneumologists, infectious disease or intensive care physicians) are trained to perform chest POCUS and use it in their everyday practice. Multiple studies have demonstrated its superiority to chest X-ray for the detection of pneumonia. In ARDS, a scoring has been developed and has shown good correlation with mortality. POCUS is very effective in detecting peripheral patterns and seems appropriate to explore COVID-19 patients. Previous studies suggest its interest in SARSCov2 infections for initial patient assessment and identification of lung damage. However, its performances have never been scientifically evaluated to date. Our main hypothesis is that point of care lung ultrasonography performed during the initial examination may identify high-risk COVID-19 patients.

This study will investigate the security and efficacy of a daily low dose of hydroxychloroquine and Bromhexine, in preventing the development of the disease from COVID-19 in Health Care Workers at a National Institute of Health In Mexico City.

The period of confinement due to COVID-19 may lead to reduced physical activity levels with negative consequences for health and quality of life in the short and long term, in case the sedentary habits are maintained over time. It is therefore essential to know the physical activity and health habits of university students during the confinement, as it could help in the design of effective strategies for the post-confinement period, as well as for any similar future situations. The general objective of the study is to know how university students have adapted their physical activity and health habits to the situation of confinement generated by COVID-19, as well as to identify the determining factors and the possible consequences. It is expected that there will be modifications in the patterns of physical activity in this situation, which could vary based on sociodemographic and economic determinants, and could affect parameters of health and quality of life. A survey will be sent to all students by email through the corresponding vice-rectorates of the sixteen participating universities (https://covid19.ehu.es/). The survey will be completed "online" anonymously. Among those participants who wish to keep participating in the study, a follow-up will be carried out one month and one year after the end of the confinement period. In this case, those subjects must indicate their willingness to keep participating and provide a contact email. The follow-up period will allow to know how physical activity and health habits are modified in the long term.

The purpose of this study is to determine whether the virus SARS-CoV-2, responsible for the disease COVID-19, is present in the abdominal cavity during emergency laparoscopic exploration in confirmed or suspected COVID-19 patients.

This study is designed to compare the efficacy of detection of COVID-19 infection using the serology test in blood sample and the PCR-based test in the nasopharyngeal (NP) and sputum sample. Furthermore, it aims to evaluate the temporal trend of appearance of IgM and IgG in blood.

The Nancy Cov-H-AKI: study is a prospective, non-randomized, monocenter study performed in patients hospitalised for either the severe or the critical form of Covid-19. The main objective of the Nancy Cov-H-AKI study is to evaluate the association of variations (from inclusion to 72H post-inclusion) of 5 blood-based cardio-vascular-renal biomarkers selected a priori, cardiac (NT-proBNP), coagulation (D-dimers), related to the renin angiotensin aldosterone system (ACE2) and renal (Penkid, and NGAL) with the appearance of acute kidney injury KDIGO grade 1 or higher OR cardiac injury in patients hospitalised for either the severe or the critical form of Covid-19

This randomized open labeled clinical trial will include one hundred healthy healthcare workers who will be randomly assigned into four groups of twenty-five each to receive either levamisole, Isoprinosine, combined levamisole and isoprinosine or no-intervention for two months to detect the impact of Levamisole and Isoprinosine as immune-prophylaxis on the incidence of COVID-19 infection. Participants will be followed-up for three months clinically and laboratory. Blood samples will be collected prior to randomization and during follow up.

The cardiovascular effects of coronavirus disease 2019 (COVID-19) are not yet fully known. We conducted a prospective and dynamic echocardiographic study to investigate the cardiac structural and functional changes in COVID-19 patients in intensive care unit (ICU).

Background: COVID-19 is a worldwide pandemic and currently there is no effective therapy or vaccine. SARS-CoV-2, the virus that causes the COVID-19 respiratory infection, appears to be very contagious however all the modes of transmission are unclear. Transmission may occur in up to 25 percent of cases when there are no symptoms (asymptomatic). Before there are any symptoms, droplet spray during speaking may increase transmission from person to person; most of the spray is saliva. Researchers at the NIH would like to test saliva for the virus before symptoms are reported. Additionally, they would like to examine the importance of using masks to prevent transmission. They hope to better understand how COVID-19 is spread among people and how it can be prevented. For this study they would like to collect samples from the nose (nasopharyngeal swab), mouth (spit sample), eye (conjunctival fluid) and blood to test for the virus and if it is contagious. Objectives: To determine if the SARS-CoV-2 virus is present in saliva in asymptomatic individuals who are COVID-19 positive. To determine if using masks can prevent transmission. Eligibility: People ages 18 and older without symptoms or with mild symptoms (e.g., low grade fever, mild malaise, minor sore throat, runny nose, or sneezing) who have been in close contact (e.g. live in the same house) with someone who has tested positive for COVID-19 or people who have tested positive for COVID-19 and have mild (e.g., low grade fever, mild malaise, minor sore throat, runny nose, or sneezing) or no symptoms. Design and Procedures: For screening, interested participants will contact a study team member. The interested participant will be asked to provide documentation of COVID-19 positive status, their symptoms, or their contact to a COVID-19 positive person. Participants will be asked to come to the NIH drive-up COVID-19 testing site or NIH Clinical Center (Bethesda, MD) for 2 or more visits in 15 days for the following procedures: nasal swab for COVID-19 and viral load, verbal symptom assessment, saliva collection, and speaking exercise to capture oral fluid. During this time, participants will also be asked to participate in phone calls with the study staff and to complete questionnaires electronically. Participants will have weekly telephone calls to discuss their symptoms and 2-5 drive-up visits to the NIH within 28 days. If visits are scheduled at the Clinical Center, participants will have the option to participate in providing blood sample(s), a conjunctival swab and 1-2 salivary gland biopsies. If a participant has tested positive, they may be asked to return to the NIH after they have recovered from COVID-19 for additional sampling. The following procedures are part of this research: Speaking exercise - participants will be asked to read a short script with and without wearing a mask. The droplets they produce while they speak will be collected. Saliva collection - participants will spit into a cup and have saliva collected from different areas of the mouth. They should not eat 90 minutes before this but drinking water or juice is acceptable. They may have their tongue painted with a sour liquid to increase their saliva. Nasal swab- participants will have a swab rubbed inside their nose. Nasopharyngeal swab - participants that are close contacts of COVID-19 positive individual(s) and need a COVID-19 test, will have a swab inserted through the nose to rub the back of their throat. Questionnaires - participants will complete questionnaires about their symptoms electronically at home. The following procedures are optional for participants to agree to participate in and will be performed in the Clinical Center: Blood sample(s) - participants will have blood collection via venipuncture. Conjunctival swab - participants will have the inner lower eyelid wiped with swab. Minor salivary gland biopsy - participants will have tiny glands in mouth removed. Procedure will be done in the hospital. Participants will be paid up to a total of $300 for the study, based on the number of visits to NIH and the types of procedures performed. Payment will be: $50 on Day 1, Day 15 and at the recovery visit. Participants who agree to the optional conjunctival swab and/or biopsy will be paid $50 for each conjunctival swab (up to 1) and/or $50 for each salivary biopsy (up to 2). If at any time the participants start to have moderate or severe respiratory symptoms, their participation in the study will end and they should seek care with their local provider.
