Active clinical trials for "COVID-19"

It is aimed to measure the general health information of Turkish physicians about covid 19 pandemic, to evaluate anxiety levels and to evaluate future expectations in this period.

Background: During the current COVID-19 pandemic there is urgent need for information about the natural history of the infection in non-hospitalized patients, including the severity and duration of symptoms, and outcome from early in the infection, among different subgroups of patients. In addition, a large, real-world data registry can provide information about how different concomitant medications may differentially affect symptoms among patient subgroups. Such information can be invaluable for clinicians managing chronic diseases during this pandemic, as well as identify interventions undertaken in a naturalistic setting that have differential effects. Such factors may include patient diet, over the counter or prescription medications, and herbal and alternative treatments, among others. Identifying the natural disease history in patients from different demographic and disease subgroups will be important for identifying at-risk patients and effectiveness of interventions undertaken in the community. Objectives: The purpose of this study is to understand at the population level the symptomatic course of known or suspected COVID-19 patients while sheltering-in-place or under quarantine. Symptoms will be measured using a daily report derived from the CTCAE-PRO as well as free response. Outcomes will be assessed based on the duration and severity of infection, hospitalization, lost-to-follow-up, or death. As a patient-centric registry, patients themselves may propose, suggest, and/or submit evidence or ideas for relevant collection.

Growing evidences are showing the usefulness of lung ultrasound in patients with COVID-19. Sars-CoV-2 has now spread in almost every country in the world. In this study, the investigators share their experience and propose a standardized approach in order to optimize the use of lung ultrasound in covid-19 patients. The investigators focus on equipment, procedure, classification and data-sharing.

The project is a part of the "Protocol for a multicentre study of nosocomial SARS-CoV2 transmission: The NOSO-COR Project" registered in ClinicalTrials (NCT04290780). In the current pandemic context, medical resources have often been exceeded. Developing, using artificial intelligence techniques, an algorithm capable of detecting patients at risk of acute respiratory distress following Sars-Cov2 infection could help physicians to optimize the treatment of patients and health decision-makers to optimize resources. Thus, the goal of this project is to create a prediction model using artificial intelligence to predict an unfavorable evolution of Covid-19 at the hospital admission of patients

Evaluation of the efficacy and safety of TCM differential treatment of COVID-19 in Jiangsu Province based on the historical prospective multicenter cohort study.

Background: COVID-19 virus infection differs among people. Some people have no or mild symptoms. For others, COVID-19 is life threatening and causes damage to the body s organs. Researchers want to better understand the virus to learn how to kill it. Objective: To understand how the COVID-19 virus causes wide differences in how sick one can become from the infection. Eligibility: People ages 18-80 with COVID-19 infection Design: Participants will be screened with a review of their medical records. Participants who enter the study at the beginning of their COVID-19 infection will stay in the hospital until they are healthy enough to go home. Those who enter after they have recovered may need to stay in the hospital 1-2 nights to perform the study tests. Participants will have MRI and CT scans of the brain, heart, and lungs. They will lie in a machine that takes pictures of the body. For the MRI, soft padding or a coil will be placed around their head and chest. They may receive a dye injected into a vein. Participants will have an ultrasound of the kidneys and heart. Participants will provide blood and urine samples. They will provide nasal swabs. Participants will have a bronchoscopy. A thin tube will be placed through the nose or mouth into the airway. Saltwater will be squirted into the lungs and removed by suction. Participants may provide a spinal fluid sample. A needle injected into the spinal canal will obtain fluid. Participants will have lung and heart function tests. At various points after recovery, participants will repeat many of these tests.

Coronavirus Pathology is frequently associated with both diabetes mellitus and metabolic syndrome. In particular, results of observational studies and meta-analyzes configure diabetes as one of the main risk factors for the development of complications and unfavorable course of SARS (Severe Acute Respiratory Syndrome) and MERS (Middle East Respiratory Syndrome), the syndromes caused respectively by SARS- VOC coronavirus and MERS-COV coronavirus. The available data confirm this association also in the clinical picture of the infection supported by SARS-COV 2 (COVID-19). In the epidemic outbreak that erupted at the beginning of 2020 in the Lombardy Region, about two thirds of the patients who died from COVID-19 were affected by diabetes mellitus. COVID-19 occurs in 70% of cases with an inflammatory pathology of the airways that can be fed by a cytokine storm and result in severe respiratory failure (10% cases) and death (5%). At the moment, the mainly involved pathophysiological molecular mechanisms are not clearly defined. It has been hypothesized that the transmembrane glycoprotein type II CD26, known for the enzyme activity Dipeptilpeptidase 4 exerted by its extracellular domain, may play a fundamental role in this process. In addition, it is considerably expressed at the parenchyma and lung interstitium level and carries out both systemic and paracrine enzymatic activity, modulating the activity of various proinflammatory cytokines, growth factors and vasoactive peptides at the level of the deep respiratory tract. The pulmonary parenchyma and the interstitium express significantly the Dipeptilpeptidase 4 protein, which in the Middle East Respiratory Syndrome favors the entry of the virus into the cells, thus allowing the virus to replicate within the cells and thus spread throughout the cell inside the organism. Dipeptilpeptidase 4 regulates the function of bioactive peptides and above all of cytokines, vasoactive peptides and chemokines present at the level of the mesothelium, of the deep respiratory tract (alveolar epithelium and alveolar bronchus), of endothelial and immune cells triggering the inflammatory storm. In line with this evidence, it has been hypothesized that acute respiratory disease from Coronavirus may depend on the massive localization of Dipeptilpeptidase 4 in lung tissue. Furthermore, the involvement of Dipeptilpeptidase 4 in other chronic respiratory diseases has been demonstrated. Starting from these observations we hypothesized that the selective blockade of Dipeptilpeptidase 4 can favorably modulate the pulmonary inflammatory response in the subject affected by COVID-19. Among the drugs that selectively block Dipeptilpeptidase 4, the one with greater affinity precisely for Dipeptilpeptidase 4 is Sitagliptin.

Some studies have shown that the main pathogenesis of patients with covid19 is related to ACE2 receptor. Lung is one of the main organs, and there are many ACE2 receptors in cardiovascular system. ACEI / ARB is the main target of antihypertensive drugs. Previous reports suggested that there were large number of patients with covid19 also suffered from hypertension, suggesting that patients with hypertension may be the susceptible to covid19. Therefore, we try to follow up the patients admitted to Hankou hospital to explore the impact of hypertension and hypertension treatment on the severity and prognosis of patients with covid19, so as to provide new methods for the treatment of patients with covid19 in the future.

COVID-19 has adversely affected the healthcare system across the world. The world was not prepared for global outbreak of infectious diseases. The rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is enabling researchers worldwide to acquire a large amount of clinical data regarding coronavirus disease (COVID-19). The COVID-19 infection severely affects the respiratory system in the critical cases and results in mortalities. The affected people experience a dry cough, fever, breathing problems, diarrhea, muscle pain, and sore throat. Besides that, some of the evidence from Italy, South Korea, China, and Spain suggest that the COVID-19 cases also lose their senses of smell and taste resulting in alterations in those patients. The objective of this proposed study is to determine whether COVID-19 cases have Olfactory and gustatory dysfunctions as a hallmark indicator and can be used as diagnostic tools for the isolation of suspected people. Investigators are presenting a prospective proportional case-control study that is conducted to investigate the COVID-19 cases with anosmia and /or Ageusia in a university hospital in Riyadh, Saudi Arabia. The sample size of this case series would be 250 cases of suspected COVID-19 patients. The cases included in the study are analyzed prospectively to determine if the cases had a history of anosmia and /or Ageusia, and then tested for the alteration of these senses through a panel of standardized odors/taste strips. That is looked at statistically allowing us to confirm the proposed effectiveness of these tests as a diagnostic tool.

Blood samples from participants who have recovered from COVID-19 infection will be obtained and studied. The goal of the research is to identify antibodies that have been generated by the patient to fight the COVID-19 infection. By identifying the most effective antibodies, scientists can make specific antibodies to use to prevent future coronavirus outbreaks or to treat patients with severe disease.
