Active clinical trials for "COVID-19"

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which first appeared in China, in December 2019 and is now spreading worldwide and poses a great threat to public health. In 12th July 2020, the total number of cases worldwide was about 13 million cases with case fatality rate of 4.4% and in Egypt the total cases was 81158 and case fatality rate was 4.6%. (1,2). In recent years, novel coronaviruses emerge periodically in different areas around the world. Severe acute respiratory syndrome coronavirus (SARS-CoV) occurred in 2002, which reportedly infected 8422 people with about 10% case fatality rate (3). Middle East respiratory syndrome coronavirus (MERS-CoV) was first identified in 2012 in Saudi Arabia, bringing a total of 1401 MERS-CoV infections, and about 35% case fatality rate (1). All the infection cases and recent epidemics show that coronaviruses impose a continuous threat to human beings and the economy as they emerge unexpectedly, spread easily, and lead to catastrophic consequences. As the number of recovered patients with COVID-19 continues to be increasing, the strength and duration of immunity after infection is an important point to be studied. Moreover, understanding this issue is a critical point for controlling this epidemic as they are the key for herd immunity and for informing decisions on how and when to ease physical distancing restrictions and to be ready for other waves of the infection. There is currently no evidence if the people who have recovered from COVID-19 have antibodies and protected from a second attack of infection or future wave of this pandemic or not. Therefore, we will carry out a longitudinal study of immunity in recovered patients to assess SARS-Cov2 patients' risk for future reinfection.

The process by which neutrophils expel DNA together with various proteins to the outside, forming a network structure called Neutrophil Extracellular Traps (NETs) constitutes a particular cell death that involves the destruction of the nuclear membrane before the plasmatic one. This process is called NETosis and differs from other known forms of cell death, such as necrosis and apoptosis. This process, however, if exaggerated, brings local or systemic damage. Viruses are known for their ability to evade the body's immune response. Only recently has it been seen that they can act as triggers for NETosis process. In fact, many viruses can stimulate neutrophils to produce NETs. Virus-induced NETs can begin to circulate in an uncontrolled manner, leading to an extreme systemic response of the body with the production of immunocomplexes, cytokines, Interferon I etc. To date, there are no data in the literature on the role of NETs in Covid-19 infection, a viral infection that leads to highly lethal interstitial pneumonia and for which there is currently no vaccine or specific therapy. Advanced forms of Covid-19 are often characterized by hyperinflammation ("cytokine storm") with the development of an ARDS-like condition. Furthermore, reports of micro and macro thrombotic phenomena such as microangiopathy, pulmonary embolism (which has led to a careful evaluation procedure for antithrombotic prophylaxis and/or coagulation in Covid-19 patients) are increasingly frequent. The primary objective of the study is to understand if NETs can be implicated in the response to Covid-19 and by which mechanisms. Concrete therapeutic proposals could derive from the knowledge and enhancement of this form of innate immunity. To do this, it will be necessary to evaluate the activity of NETosis in Covid-19 patients and evaluate whether the clinical course of the disease (worsening vs healing) determines the degree of NETosis activity. Therefore, the association between mortality from Covid-19/survival and NETs activity will be studied. Secondary objectives concern the possibility of studying the associations among NETosis markers and blood inflammation markers and among NETosis markers and the onset of peripheral or deep vein thrombosis. Finally, the possibility that the plasma deriving from Covid-19 patients could trigger the NETosis process in vitro will be evaluated.

This study will describe the recovery process of patients undergoing cardiac surgery during the covid-19 pandemic. This will focus on hemodynamic failure and organ dysfunction after surgery. Capturing real-world data and sharing international experience will inform the management of this complex group of patients who undergo surgery throughout the COVID-19 pandemic, improving their clinical care. This investigator-led, non-commercial, non-interventional does not collect any patient identifiable information.

JUPITER is an observational study protocol that aims to understand factors that can help prevent/mitigate the spread of COVID-19 and understand factors that help reduce disease progression in patients with COVID-19. We aim to accomplish this by obtaining self-reported historical and longitudinal data from study participants.

The COVID-19 emerging disease due to a novel coronavirus (SARS-CoV-2), started in Wuhan, China, last December, 2019. In the past three months, the virus has spread rapidly worldwide to reach the pandemic threshold. Research has since been carried out and is intensifying in order to describe the clinical characteristics of infected patients, to identify the prognostic factors of acute respiratory distress syndrome [ARDS] and the death; and to assess the effectiveness of new antivirals and therapeutic strategies to treat COVID-19. Treatments currently being investigated include: Potentially effective treatments: (hydroxy)chloroquine, Remdesivir, Lopinavir, Ritonavir +/- IFN-ß-1a (currently evaluated in the European discovery trial), methylprednisolone in patients with ARDS; Potentially harmful treatments: antihypertensives such as converting enzyme inhibitors and angiotensin receptor antagonists. We made the hypothesis that (1) patients receiving ARBs or ACEi's have a higher risk to present a serious COVID-19 infection disease and (2) patients receiving synthetic AMD (e.g. HCQ and CQ) have a lower risk to present a serious covid19 infection disease. Using data from the French insurance health database (SNDS) and hospital discharge database (PMSI), our objectives are Main objective: To assess the risk of moderate to serious COVID-19 infections in patients using synthetic anti-malarial drugs (AMD) or anti-hypertensive drugs (Angiotensin receptor-blocking/Angiotensin-converting-enzyme inhibitors). Secondary objective : To examine the risk of moderate to serious COVID-19 infections according of age, sex, co-morbidities, level of exposure of AMD, geographical locations and underlying comorbidities. This in order to: To prevent moderate to serious COVID-19 infections in at-risk population (diabetes, elderly, respiratory failure population) using synthetic AMD. To prevent moderate to serious COVID-19 infections in at-risk population stopping angiotensin receptor-blocking and angiotensin-converting-enzyme inhibitors.

This is observational study to assess the prognosis of patients hospitalized with COVID-19 confirmed by RT-PCR and exposed to trimethylxanthine (TMX). Trimethylxanthine is the active molecule present in coffee. Due to the lack of etiologic treatments and considering interest about old treatments as an avenue for research, we conducted a comparative study aiming to evaluate the effect of 1,3,7-trimethylxanthine on COVID-19 infected patients. This is actually a study about methodology. The objective of this study is therefore not to demonstrate the effect of the substance on the disease but the importance of a rigorous methodology in scientific research. This project is called "Method and Teaching of Scientific Studies".

In this study, the content and results of the psychiatric consultation on patients in Corona Care Ward were verified retroactively, and the effects of COVID-19 patients' emotional state and psychological support and crisis intervention were assessed on their emotional state. Patients who are admitted to the COVID-19 care unit of the Catholic University of Daegu Hospital are subject to consultation with the psychiatrist. By retrospectively reviewing the medical records of the request and the results of the subjects, We collected Socio-demographic information, medical severity (oxygen saturation, chest x-ray readings, medication being administered), clinical psychological scale (PHQ-9, GAD-7, PC-PTSD-5, AIS, P4, SF-36, SCL-90-R) This study evaluates whether there is a difference in psychological scale according to differences in socio-demographic status and medical severity, and compares psychological measures before and after referral to mental health medicine to evaluate the effectiveness of psychiatric counseling.

Coronavirus disease was first diagnosed in December 2019, in the city of Wuhan, China. The World Health Organization recently declared coronavirus disease 2019 (COVID-19) as a pandemic. The infection is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It is a single-stranded RNA virus, which in humans causes mild respiratory symptoms and generally has a good prognosis. However, in a certain group of patients it manifests as severe pneumonia, respiratory distress syndrome, multiple organ dysfunction and death. The factors associated with a worse prognosis are older than 60 years, the presence of diabetes, cardiovascular disease and obesity. According to studies carried out in the Eastern world, the prevalence of liver injury in patients with COVID-19 disease varies between 14% and 53%, being more prevalent in patients with severe symptoms of COVID-19 disease. It is not really known whether the liver involvement of patients with SARS-CoV-2 infection is secondary to the direct effect of the virus on the liver. One of the mechanisms of action of SARS-CoV-2 is through the binding to the angiotensin-converting enzyme receptor, which is present in cholangiocytes, this could explain its excretion in faeces. However, liver injury could be due to the immune response generated in the body by the virus with systemic inflammatory response syndrome and the release of inflammatory cytokines such as IL6, generating direct cytopathic damage to the liver. On the other hand, it could be the product of hepatotoxic drugs administered during hospitalization, such as antibiotics, antivirals or non-steroidal anti-inflammatory drugs. Liver biopsy described microvacuolar steatosis, and a mild portal and lobular inflammatory infiltrate . Therefore, the aim this study is to assess the prevalence of liver complications (liver injury, decompensation of cirrhosis) in patients diagnosed with COVID-19 in Latin America. As secondary objectives, the investigators will describe the clinical characteristics of COVID-19 disease and identify risk factors associated with poor prognosis,

Since December 2019 the world has been shaken with an enormous global threat: the Covid-19 pandemic. This new kind of coronavirus is generating an unprecedented impact both on the general population and on the healthcare systems in most countries. Health services are trying to expand their capacity to respond to the pandemic, taking actions such as increasing the number of beds; acquiring necessary equipment to provide intensive therapy (ventilators), and calling retired health professionals and health students so they can assist the overwhelmed health care workforce. Unfortunately, these organizational changes at health facilities, along with the fears and concerns of becoming ill with the virus or infecting their families, put an enormous emotional burden on workers in health services which may lead to negative outcomes on mental health in this population. Recent cross-sectional studies in China indicate that health service workers exposed to people with Covid-19 reported higher rates of depressive and anxious symptoms. This negative impact on mental health among health workers in China has also been informally reported in other countries where the Covid-19 pandemic has been devastating in its effects (such as Spain and Italy), as well as in countries where the pandemic is becoming a growing public health problem. This is particularly relevant in regions with fewer resources (Latin America, North Africa), where there are limited means and the response from the health system is usually insufficient. Moreover, it is necessary to study these negative effects longitudinally considering that some effects will appear over time (post-traumatic stress). The COVID-19 HEalth caRe wOrkErS (HEROES) study is a large, bottom-up, South-North initiative aimed to evaluate the impact of the COVID-19 pandemic on the mental health of health care workers (HCWs). HEROES encompasses a wide variety of academic institutions in 19 LMICs and 8 HICs, in partnership with the Pan American Health Organization (PAHO) and with support from the World Health Organization (WHO). The HEROES study is led by Dr. Rubén Alvarado at University of Chile, and Dr. Ezra Susser and Franco Mascayano at Columbia U Mailman School of Public Health.

This study compares two intubation boxes, that is the Taiwan "Aerosol Box" versus the UMMC "Intubation Box". The importance of this intubation box has come to light recently in view of the COVID-19 pandemic and the fact that intubation is an aerosol-generating procedure. Risks of the healthcare worker attending to the airway of COVID-19 patients is high and the intubation box aims to minimize that and reduce contamination of the environment. The original design of the "Aerosol Box" has limitations and is not easily used by intubators. This study evaluates the clinical usefulness of an innovation of the "Aerosol Box" design that is made to be more ergonomic and increases the rate of successful intubation. Anaesthetists with more than 5 years of clinical experience in intubating airways as well as more than 20 successful intubations using videolaryngoscopy , will be available to participate. This study will employ manikin and will be a randomized cross-over trial, conducted in UM.
