Active clinical trials for "COVID-19"

Coronavirus-2019 disease (COVID-19) and community-acquired pneumonia are significant problems of modern medicine. Pneumonia is the most common severe complication of COVID-19. But at the same time, COVID-19 is not the only cause of community-acquired pneumonia. Moreover, pneumonia is only one of the numerous possible severe complications of COVID-19. Medical centers specialized for the hospital treatment of patients with severe COVID-19 and community-acquired pneumonia were organized in different regions of Russia during coronavirus pandemic-2020. The indications for hospitalization to one of these centers based in the National Medical and Surgical Center (NMSC) are: confirmed or suspected severe COVID-19 or community-acquired pneumonia. A prospective medical registry of such patients hospitalized to NMSC, is intended to analyze and compare their clinical and instrumental data, co-morbidity, treatment, short-term and long-term outcomes in real clinical practice. Stage 1. Hospital treatment in NMSC Duration of this stage: from the date of admission to the hospital up to the date of discharge from the hospital / or up to the date of death during the reference hospitalization. The date of admission to the hospital will be the date of enrollment to the study. Evaluation of electronic health record data using the Medical Information System (MIS). Assessment of the outcomes of the hospital phase (discharge from the hospital, death) and significant events (acute respiratory and pulmonary failure, requiring mechanical ventilation; cardiovascular events - myocardial infarction, cerebral stroke, acute heart failure, paroxysmal heart rhythm disturbances, bleedings, thrombosis of large vessels and thromboembolic complications). A survey of patients to clarify data on risk factors, somatic diseases, and drug therapy before hospitalization. COVID-19 was diagnosed when severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was confirmed by Polymerase chain reaction (PCR). Pneumonia was confirmed according to computerized tomography (CT) data. Stage 2. Prospective outpatient follow-up for 24 months Duration of this stage: 24 months after discharge from the hospital This work will be delivered by investigators from the National Medical Research Center for Therapy and Preventive Medicine. Evaluation of long-term outcomes and events among residents of Moscow and the Moscow Region according to a patient survey (contact by phone for 30-60 days, 6 months, 12 and 24 months after discharge from the hospital) and medical records.

A phase 2/3 multi-center randomized, double-blind, parallel arm, placebo- controlled study in Adult Subjects Hospitalized with Severe SARS-CoV-2 Positive Pneumonia to determine the potential of opaganib to improve and/or stabilize the clinical status of the patient.

COVID-19 is a viral disease induced by infection with the novel SARS-CoV-2 coronavirus. Infection arises from the inhalation of viral particles spread by an infected individual. The main virus entry pathways are the nose and mouth mucous membranes, particularly rich in ACE2 receptors, that are used by the virus to enter cells and begin its replication. Not all individuals who contract the virus fall ill, and most of those who do (about 70-80%) experience mild symptoms (fever, cough, headache, muscle aches, loss of taste and smell). If the immune system is unable to rapidly fight the virus back, the latter can attack the lungs, affeting oxygen absorption inside the alveoli and lead to pneumonia. This more severe form is observed in 20% of patients and can develop into even more serious complications requiring intensive care, with a high mortality rate. In severe cases (about 5%), the disease spreads to the entire body reaching the cardiovascular system and brain, with the risk of heart attacks, encephalitis and stroke, but it can also affect the liver, kidney and bowel. Reasons why some subjects develop a highly severe disease while others have little or no symptoms at all still remain unclear. Many researchers are trying to find an answer by investigating the human genome, and the Mario Negri laboratories are also working in this direction. The general hypothesis underlying this research project is that inter-individual genetic variations can explain the different responses to viral infection in a population, and that COVID-19 severity is, therefore, genetically determined in each infected subject.

This study is a prospective, observational multicentric study. The study population entails adult patients hospitalized with a high clinical suspicion of COVID-19 and consists of two study arms (SARS-CoV2- vs. SARS-CoV2+).This combined fundamental research project has a dual goal: on the one hand assessing immunological predisposing factors for severe infection and investigating the immunological impact of SARS-CoV2 infection, on the other hand studying viral characteristics. Furthermore, a substudy will examine the pharmacokinetics and pharmacodynamics of hydroxychloroquine in patients receiving this antiviral treatment (REVIVE susbstudy). To answer these research questions, samples will be collected from patients with a high clinical suspicion of COVID-19, hospitalized at UZ Gent and 2 participating hospitals in Ghent (AZ Maria Middelares en AZ Jan Palfijn).

The investigator hypothesis is that early implementation of early, awake prone position for patients with COVID-19 pneumonia requiring oxygen therapy will reduce the need for escalation of respiratory support. Escalation of respiratory support is defined as the need for respiratory support with HFNO, NIV or IV.

Coronavirus is a global pandemic with a high mortality rate; it is started in china in 2019 and rapidly spread worldwide, reaching its epidemic peak in March 2020 Coronavirus is a family of viruses that usually affect animals. They also can affect the respiratory system of humans, causing different manifestations such as difficulty in breathing, coughing, fever, invasive lung lesions, and viral pneumonia

The acute phase of the COVID-19 pandemic requires a redefinition of healthcare system to increase the number of available intensive care units for COVID-19 patients. This leads to the postponing of elective surgeries including the treatment of abdominal aortic aneurysm (AAA). The probabilistic rupture risk index (PRRI) recently showed its advantage over the diameter criterion in AAA rupture risk assessment. Its major improvement is in increased specificity and yet has the same sensitivity as the maximal diameter criterion. The objective of this study was to test the clinical applicability of the PRRI diagnostic method in a quasi-prospective observational patient cohort study.

This study assesses the level of distress felt by cancer patients due to the coronavirus disease 2019 (COVID-19) pandemic. Researchers also want to learn if patients prefer to receive supportive care (palliative care) in person or through telemedicine (visits by phone or video call, such as Zoom). Information from this study may help doctors better understand how COVID-19 has affected patients with advanced cancer, patients' perceptions of telehealth, and may help clinicians tailor care to patients' needs during the pandemic.

InVITE is funded by NIAID and is conducted in multiple international sites (approximately 20 sites across 7 countries). This is a study of adults who receive locally available COVID-19 vaccines through local vaccination programs. Persons will be enrolled within one day (before or after) of receipt of a COVID-19 vaccine. The study will enroll participants who receive COVID-19 vaccination at local clinics and/or study sites.

Psychological distress is commonly experienced by survivors of an intensive care admission, including patients treated during previous pandemics. Whilst data emerges about the short-term impact of COVID-19 on patients and healthcare systems, the long term impact remains unclear. The purpose of this trainee-led, multi-centre longitudinal study is to assess the short- and long-term psychological impact on patients who have survived an admission to intensive care due to COVID-19, and identify possible predictors of anxiety, depression and trauma symptoms in this patient group.
