Active clinical trials for "Coronavirus Infections"

Background: The rapid spread and high infectivity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) makes identifying an effective prophylaxis agent highly important. One of the important target populations for such intervention who are at high risk of exposure are health care workers (HCWs) who may develop disease and/or expose patients and other HCWs. Hydroxychloroquine (HCQ), currently in usage for treatment of severe Coronavirus Disease 2019 (COVID-19), has in addition to in-vitro activities of inhibition of virus replication and immunomodulation, an important role in the inhibition of pre-entry step of the virus to host cells. Such activity in the early stage of infection may play a role in prevention of disease progression. Objectives: To evaluate the effect of HCQ in prevention of clinical disease and reduction of viral shedding among HCWs following exposure to confirmed COVID-19 patients. Study design: Multi-center, randomized controlled, superiority, open label trial Setting: The study will be conducted at Rambam Health Care Campus. Eligibility: Participants eligible for inclusion will include non-pregnant adult (>18 years old) HCWs who were exposed to a confirmed case of COVID-19 without full adherence to droplet precautions. Participants will be eligible in a period no longer than 72 hours after exposure. Intervention: HCQ will be given in the intervention group in a dosage regimen of 400mg BID in the first day followed by 200mg BID for overall 10 days. Participants in the control group will receive no treatment. Treatment will be started no longer than 72 hours following exposure. Outcomes: The primary outcome will be the number of participants who develop clinical signs compatible with COVID 19 (defined in full protocol) within 14 days of exposure. Secondary outcomes will include virologically-confirmed COVID 19, disease severity (need for hospitalization, mechanical ventilation and 30-day mortality) and viral shedding duration (time between first positive PCR to last of two consecutive negative tests) for confirmed COVID 19 cases. Sample size: The trial will test for HCQ's superiority assuming a primary outcome incidence of 20% in the control group and a reduction of 50% with HCQ. The sample size required for a power of 80% (alpha 0.05) is 291 participants per each group.

The purpose of this study is to assess the safety and efficiency of an assembled modified mask in protecting health care workers against Coronavirus in case of any personal protective equipment shortage. At least 20 healthy participants will be recruited to try the modified mask. The modified masks will be made from masks that are already available as well as filters available in the pulmonary department at the Oklahoma City VA Health Care System

This is an observational study to evaluate the effectiveness of the combinations Hydroxychloroquine + Azithromycin (HCQ-AZ) and Chloroquine + Azithromycin (CQ-AZ) in the treatment of Coronavirus (Covid-19) infection in Burkina Faso.

The purpose of this study is to determine how peoples' bodies respond to exposure to COVID-19. Employees of Beaumont Health in Michigan who are older than 18 years may be eligible to participate. Participants from other high-risk groups who are not Beaumont employees may also be recruited, as may family members of Beaumont employees who have tested positive for COVID-19. Participants will have blood drawn two or more times for serology testing. This serology test will determine if participants have detectable levels of the antibodies that our bodies develop to fight COVID-19 infection. Participants will fill out a questionnaire each time they provide a blood sample. The questionnaires include questions about participants' personal traits; their health; general questions about their risk to exposure; job and risk of exposure; symptoms, diagnosis, treatment of COVID-19 since last blood draw. Researchers will monitor participants' medical records in a confidential manner for one year after the last blood draw to help determine if people who develop antibodies to COVID-19 are protected against developing a COVID-19 infection in the future.There may be no direct benefits for participants; however, information from this study may benefit other people by increasing our understanding of COVID-19, how it spreads from person to person, and how people respond to fight off the infection.The results of the serology test are used for research only and will not affect clinical decisions regarding participants' treatment or quarantine

For limiting COVID-19 spreading, the World Health Organisation (WHO) recommended worldwide confinement on 2010. In France, unessential institutions were closed on March 14th and population confinement was decided on March 17th. Quarantine and/or confinement could lead to psychological effects such as confusion, suicide ideation, post-traumatic stress symptoms or anger COVID-19 outbreak highlighted a considerable proportion of health care workers (HCW) with depression, insomnia, anxiety and distress symptoms. In front line, facing the virus with the fear of contracting it and contaminate their closest. During previous outbreaks (H1N1, SARS), HCWs have been shown to experience such negative psychological effects of confinement as well as work avoidance behaviour and physical interaction reduction with infected patients (4-7). In France, Covid 19 outbeak led to increase ICU bed capacity with a full reorganization of the human resources. Some caregivers were reassigned to newly setup units admitting or not Covid-19 patients. In the same time, non-caregivers were also encouraged to work at home whenever possible. Thus, every hospital staff member's private and professional life could be altered by the Covid-19 outbreak. As all these changes in the daily life could induce psychological disturbances, the present study was aimed at assessing the acute anxiety level (main objective) of the staff in our Tertiary University Hospital, (6300 employees). Secondarily, the self-reported insomnia, pain, catastrophism and work avoidance behaviour levels were assessed

The Covixyl-V LAEH Nasal Spray's safety and efficay is clinically tested for use in subjects with COVID-19 infection. A randomized, double-blind, multi-center study is conducted to evaluate the efficacy and safety of ethyl lauroyl arginate hydrochloride (LAEH) formulation versus a matching placebo formulation administered as a nasal spray to reduce viral load from nasal area of subjects with coronavirus disease 2019 (COVID-19).

Fibromyalgia patients and controls living in the same household will be evaluated for levels of resilience, covid-19 related anxiety, coronavirus disease 2019 related obsession, quality of life and pain and comparisons and correlation analyses will be carried out.

Coronavirus Disease 2019 (COVID-19) (previously called 2019-nCOV acute respiratory disease) is caused by SARS-CoV-2, a positive-sense single-stranded RNA virus of the coronavirus family. The coronaviruses are largely responsible for the common cold, the 2002 SARS outbreak in Guangdong, China, the 2012 MERS outbreak in Saudi Arabia, and the present COVID-19 outbreak that originated in Wuhan, China. Much has been reported by way of systemic injury caused by COVID-19 affecting the cardiovascular, hepatic, nervous systems. These conditions are likely the result of the virus overwhelming the immune system. For these reasons, the investigators wish to conduct this study using existing medications off-label, and over-the-counter supplements to support the immune response, prevent lasting injury, and hasten the recovery from COVID-19.

The Apple Respiratory Study, a collaboration between researchers at Apple Inc. (the "Study Sponsor" or "Sponsor") and the Seattle Flu Study team at the University of Washington (UW) (the "UW Study Team"), is a prospective, longitudinal cohort, low risk Study to collect certain data from Apple Watch and iPhone to determine whether such data can detect physiologic and non-physiologic changes in individuals associated with respiratory illnesses due to influenza, SARS-CoV-2 and other respiratory pathogens (the "Study").

The Coronavirus disease 2019 (COVID-19) is causing a global pandemic with high morbidity and mortality among adults and mainly the elderly. Children seem to be little or not affected by this infection. It is estimated that children could be asymptomatic or pauci-symptomatic carriers and thus be vectors of the disease. This is why measures to close schools and confine populations have been decreed in a large number of countries, including France. However, there are only a few data on the prevalence of COVID19 disease in children. The deconfinement strategy depends on data on the prevalence of the disease, especially in children. Investigators propose to evaluate the incidence of Covid-19 in preschool and elementary schools children in the city of Nice (South of France) during the pandemic period using a local prospective study of 914 children
