Active clinical trials for "Coronavirus Infections"

Covid-19 is associated with a wide range of symptoms and clinical trajectories, and early identification of patients at risk for developing severe disease is desirable. Several risk markers and comorbidity profiles have been proposed but their relative importance in unselected patients admitted to hospital with Covid-19 remains unclear. This study aims to assess the prognostic value organ specific biomarkers, viral dynamics and immune response markers in patients infected with SARS-CoV2.

Our project intends to independently develop a fully enclosed rapid detection system for a total of 22 pathogens, including SARS-CoV-2, on the basis of the QIAstat-Dx fully automatic multiple PCR detection platform. The reasonably designed experiments are used to verify the performance of the cartridge detection and prove its clinical application value. The 22 pathogens tested in this project includes 4 coronavirus subtypes, A / B flu, parainfluenza virus, respiratory syncytial virus, etc., which is of great significance for the differential diagnosis of similar patients.

The overall objective of the study is to determine which treatments (e.g. immune modulator drugs) have the most favorable benefit-risk in adult patients hospitalized with COVID-19 either diagnosed with moderate or severe pneumonia requiring no mechanical ventilation or critical pneumonia requiring mechanical ventilation. The specific aims of this Covid19 cohort are to collect observational data at regular intervals on an ongoing basis in order to embed a series of randomized controlled trials evaluating a various set of interventions for patients with COVID-19 pneumonia. The study has a cohort multiple Randomized Controlled Trials (cmRCT) design.

Patients suffering from pneumonia due to SARS-CoV-2 infection, after admission to the Intensive Care Unit (ICU), are susceptible to development of various functional sequelae, increased risk of chronic diseases, increased mortality rates and existence of relevant impacts on their quality of life in the months and years that follow the ICU admission. The present study aims to assess the determinants of health-related quality of life and patient-centered long-term outcomes among patients recovered from SARS-COV-2 pneumonia, after discharge from the ICU, its determinants and predictors, in Portugal. It is a multicenter prospective cohort study of adult patients admitted at the ICU due to proven or suspected SARS-CoV-2 infection, included 90 days after discharge from the ICU. The primary outcome is one-year health-related quality of life assessed by the EQ-5D-3L. The secondary outcomes are all-cause mortality, rehospitalizations, return to work or study, the degree of dependence and functional capacity, symptoms of anxiety, depression and post-traumatic stress, level of physical activity and cognitive, renal and respiratory functions after ICU discharge. Investigators will collect data by means of structured telephone interviews, at a 12 months follow up period.

The aim of this study is to determine the risk factors for development of ventilator-associated pneumonia (VAP) and to identify the prognostic factors of VAP among Coronavirus Disease 2019 (CoViD-19) patients. We hypothesized that CoViD-19 serves as a high risk factor for the development of VAP and it affects clinical outcome measures negatively.

Morbidity, mortality and progress depends on systemic inflammation especially in ARDS patients. Previous studies claims that the proportion of mean platellet volume to platellet which can simply be determined with simple blood tests that are performed at admission, might predict the mortality in ARDS patients. Covid-19 pneumonia has a very similar clinical outlook with ARDS. Therefore we decided to research whether that proportion is legitimate for detecting the progress of Covid-19 pneumonia or not.

Infection with coronavirus SARS-CoV2 (COVID-19 disease) is unique with its speed of propagation, structural medical reorganizations and length of stay in intensive care needed, diversity of the affected population (in particular between young persons or fragile subjects), and impact on physical and mental health generated by confinement of populations. Fatigue is a major component of COVID-19. Global muscular weakness is related to immobility, inflammation, corticosteroids treatment, hypoxemia due to pulmonary and/or cardiac infectious attacks and undernutrition suggests major physical functional repercussions. Thus, patients affected by COVID-19 with acute hospital management require sometimes complex rehabilitation management. Retrospective studies on physical functional capacities in patients infected with SARS CoV1 showed long term physical activity limitations.

In late December 2019, several local health facilities reported clusters of patients with pneumonia of unknown cause that were epidemiologically linked to a seafood and wet animal wholesale market in Wuhan, Hubei Province, China. It is now confirmed that the etiology of this outbreak is a novel coronavirus, namely, 2019-nCoV. Of critical importance is rapid and simple diagnostic method to be used in clinical settings to timely inform and refine strategies that can prevent, control, and stop the spread of 2019-nCoV. Recombinase aided amplification (RAA) assay is a novel isothermal nucleic acid amplification technique in recent years, which has a variety of the advantages including high specificity and sensitivity, rapid detection (30 min), low cost, low equipment requirements and simple operation. The has successfully detected a variety of pathogens using this technique. To develop a RAA assay for 2019-nCoV with the advantages of high speed, simple operation and low cost, and overcomes the shortcomings of the existing molecular detection methods. The investigators established a real time reverse-transcription RAA (RT-RAA) assay for detection of 2019-nCoV. This assay was performed at 42°C within 30min using a portable real-time fluorescence detector, Recombinant plasmids containing conserved ORF1ab genes was used to analyze the specificity and sensitivity. Clinical specimens from patients who were suspected of being infected with 2019-nCoV were used to evaluate the performance of the assay. In parallel, The investigators also used the commercial RT-qPCR assay kit for 2019-nCoV as a reference.

Outbreak of 2019 Novel Coronavirus infection quickly spread to the world. Confirmed patients were isolated and treated in our department. 2019 Novel Coronavirus was detected in multiple organ system. Clinical data was recorded to investigate the its relationship with viral detection.

Outbreak of 2019 Novel Coronavirus infection started in Wuhan and quickly spread to the world. Suspected patients were isolated and treated in our department. Clinical data was recorded to investigate the clinical features of patients confirmed and excluded diagnosed of 2019 Novel Coronavirus infection.
