Active clinical trials for "COVID-19"

This study will assess the prevalence and incidence of COVID-19 infection in patients with chronic plaque psoriasis on immunosuppressant therapy.

Residents in nursing homes for the senior citizens (NH) are at high risk for death from COVID-19. We investigated whether repeated non-mandatory RT-PCR SARS-CoV-2 surveillance of NH staff and visitors reduces COVID-19 incidence rates in NH residents and allows to reduce visiting restrictions.

The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a new coronavirus discovered in December 2019 in Wuhan, China and currently responsible of a worldwide outbreak and the death of more than 55,000 patients in France. The more severe form of COVID-19 disease induces a pneumonia with profound hypoxemia which may require invasive mechanical ventilation. It is estimated that 5% of COVID-19 patients are admitted to the Intensive Care Unit (ICU) for management. Hospital mortality in patients who develop severe acute respiratory distress syndrome (ARDS) ranges between 40% and 60%. The investigators purpose to investigate the pathological findings of COVID-19 patients who died from ARDS in the ICU by doing post-mortem lung biopsies

Coronavirus disease 2019 (COVID-19) is a respiratory tract infection caused by a newly emergent coronavirus (SARS-CoV-2) that can progress to severe multiorgan disease requiring hospitalization. The medium and long-term impact in survivors of COVID-19 on lung function, imaging by thoracic CT, exercise capacity, and health-related quality of life and the relation of these parameters remains to be determined.

The investigators are enrolling 100 healthcare Provider volunteers (n=100) from across the United States to help to evaluate and document the financial impact of COVID-19 on Physicians and other healthcare Providers. This investigation will compare individual Physician revenues before and after the advent of the COVID-19 pandemic. The investigators expect to be able to differentiate between revenues lost due to the COVID-19-driven business recession and revenues lost due to the manipulation of reimbursement processes by insurance companies. The inextricable linkage between Payer and Physician revenues suggests that Payer revenues are higher at the direct expense of Physicians, since both streams come from the same sources of funding. The secondary objective is aimed at revealing the methods Payers use to retain more money.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection is a pandemic, which has affected approximately 4 lakhs individuals and claimed 16,362 deaths till now. SARS-CoV-2 has been associated with myocarditis and renal dysfunction. Patients hospitalized for Covid-19 severe infection are more prone to excessive coagulation activation leading to thrombotic events both in the venous and arterial circulations, due to excessive inflammation, platelet activation, endothelial dysfunction, and stasis. Nearly 20% of COVID-19 patients present severe coagulation abnormalities, which may occur in almost all of the severe and critical ill COVID-19 cases. Concomitant venous thromboembolism (VTE), a potential cause of unexplained deaths, has been frequently reported in COVID-19 cases, but its management is still challenging due to the complexity between antithrombotic therapy and coagulation disorders. The importance of high D-dimer and Fibrin degradation product level to determine the patient prognostic and the risk of thrombosis is known. In a French study, it was found that a high rate of thromboembolic events in COVID-19 patients treated with therapeutic anticoagulation, with 56% of VTE and 6 pulmonary embolisms. Preliminary reports on COVID-19 patients' clinical and laboratory findings include thrombocytopenia, elevated D-dimer, prolonged prothrombin time, and disseminated intravascular coagulation. COVID-19 patients with acute respiratory failure present a severe hypercoagulability rather than consumptive coagulopathy. Another study highlights this common finding in most COVID-19 patients with high D-dimer levels which are associated with a worse prognosis. Cases showed significantly higher fibrinogen and D-dimer plasma levels versus healthy controls (p < 0.0001). Markedly hypercoagulable thromboelastometry profiles were observed in COVID-19 patients, as reflected by shorter Clot Formation Time (CFT) in INTEM (p = 0.0002) and EXTEM (p = 0.01) and higher Maximum Clot Firmness (MCF). Fibrin formation and polymerization may predispose to thrombosis and correlate with a worse outcome. Global VE tests provide a more physiologic assessment of coagulation and should be considered to guide blood transfusion requirements in liver transplantation and other major surgery. Its application in patients with Covid19 or in a critical care setting requires more data. Viscoelastic tests, which include TEG, ROTEM, and Sonoclot, offer a means of assessing the activity of pro-and anticoagulant pathways, hyperfibrinolysis, and excessive clot lysis. Assessment of clot formation can be performed in 10 to 20 minutes as a point of care (POC) test; however, assessment of clot lysis takes 30 to 60 minutes. SIRS and sepsis trigger the release of endogenous heparinoids, or a heparin-like effect (HLE), due to small endothelium/mast cell-derived glycosaminoglycan's, which can be detected on heparinase-treated viscoelastic assays. Viscoelastic testing of global coagulation such as thromboelastometry and Sonoclot has been proposed as a superior tool to rapidly diagnose and help guide resuscitation with blood products and anticoagulation. it is deemed necessary to determine the influence of Covid 19 on coagulation parameters using point of care coagulation using sonoclot and conventional coagulation tests. In this prospective trial, the investigators aim to evaluate coagulation abnormalities via traditional tests and whole blood Sonclot profiles in a group of 50 consecutive patients with critically ill COVID-19 patients admitted to the Covid ICU OF Nehru Hospital extension, Postgraduate Institute of Medical Education and Research, Chandigarh.

The coronavirus disease 2019 (COVID-19) initially developed at the beginning of December 2019 in Whuan, Hubei province of China has spread all over the world. Beside the most common symptoms at onset of illness including fever, fatigue, dry cough, myalgia and dyspnoea, there are less common symptoms such as headache abdominal pain, diarrhoea, nausea and vomiting. The proportion of patients complaining gastrointestinal symptoms is variable between 3,4% and 17,0%. Interestingly, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) RNA has been reported to be detectable in 50% of patients' stool samples and in these patients around the 50% had diarrhoea. SARS-CoV2 transmission has been reported to be through droplets. However, mounting evidence indicates that SARS-CoV2 has a tropism for the gastrointestinal tract and is excreted with faeces. Accordingly, a faecal-oral route of transmission of the virus has been recently postulated. Indeed, SARS-CoV2 binds to host ACE 2 receptors (ACE2) to entry into cells which are abundantly expressed by intestinal epithelial cells and regulate intestinal inflammation. Taken together, this evidence could provide a rational basis for the development of gastrointestinal symptoms reported by COVID19 infected patients. Primary aim: to evaluate the prevalence and prognosis of gastrointestinal symptoms in patients admitted to hospital for COVID19 disease Secondary aims to evaluate long term consequences of COVID-19 on gastrointestinal symptoms to evaluate long term consequences of COVID-19 on the development of post-infection irritable bowel syndrome (PI-IBS) to evaluate long term consequences of COVID-19 on the development of post-infection dyspepsia to assess the clinical and laboratory predictors (risk factors) of post-infection gastrointestinal symptom development

The investigators planned to analyze the effect of Covid-19 fear and anxiety on the daily life, sleep quality and depression-anxiety levels of fibromyalgia patients.

The term recovery from COVID-19 caused by SARS-CoV-2 is unverified because the infection leaves many symptoms due to permanent effects on multiple organs; The primary objective of this research is to understand acute and chronic long COVID symptoms by asking questions detecting patient's experience especially symptoms lasting for several months which is known as chronic fatigue syndrome(Myalgic encephalitis). The study focuses on symptoms describing Myalgic encephalitis which may still affect COVID patients for several months after the infection along with making a big picture about rare symptoms that may the patient experienced during or after the infection. A secondary objective of this research is to focus on the long-term sequelae effects and comorbidities following COVID-19 vaccination.

The pandemic triggered by the new SARS-CoV-2 presents the German health system with previously unknown challenges. There are currently no effective therapies for the treatment of the SARS-CoV-2 lung disease Covid-19. The aim of the joint project PROVID is to draw conclusions from the often very different clinical appearance of infections with the SARS-CoV-2 pathogen in order to improve patient care through targeted clinical management. The effects of infections with the SARS-CoV-2 pathogen are wide-ranging and include a spectrum from symptomlessness to infections of the upper respiratory tract, uncomplicated but also severe pneumonia with lung failure and high mortality. PROVID will first check whether certain host factors determine the severity and / or the course of Covid-19. Research is also being carried out into whether the molecular and clinical values of Covid-19 patients differ from those of patients with pneumonia caused by other pathogens. In addition, it will be tested whether specific molecular markers describe the severity of the disease and are suitable as an aid for targeted therapy for Covid-19. PROVID is an interdisciplinary joint project made up of three sub-projects that are being implemented at three locations (Charitè-Universitätsmedizin Berlin, Universität Leipzig IMISE and CAPNETZ STIFTUNG / Hannover). PROVID is based on three clinical research platforms with a high track record in recruiting patients with high-quality data and biomaterials on the one hand and guideline-changing results on the other hand: CAPNETZ (competence network CAP, since 2002, world's largest database and biobank for CAP), PROGRESS (Pneumonia Research Network on Genetic Resistance and Susceptibility for the Evolution of Severe Sepsis, since 2007) and CAPSyS (systems medicine of community-acquired pneumonia, since 2014). The COVID-19 patients are recruited into 3 different patient cohorts via these 3 research platforms. 1. PROVID-CAPNETZ, 2. PROVID-PROGRESS, 3. PROVID-CAPSyS.
