There is one clinical trial.
COVID-19 pandemic has developed worldwide in less than 4 months. While most patients have a mild or uncomplicated disease (80%), approximately 15% need hospital care and 5% intensive care. Severe cases are characterized by pulmonary involvement which may progress to acute respiratory distress syndrome (ARDS). Early identification of patients who are likely to get worse is therefore a major issue. While, chest X-ray has poor diagnostic performances, pulmonary computed tomography (CT scan) seems very sensitive (97%) and quite specific of COVID-19. Sub-pleural bilateral ground-glass pattern can precede the positivity of RT-PCR for SARS-CoV-2. CT scan is now considered as the best imaging test to assess COVID-19 patients and is recommended as first-line diagnosis tool by the French Society of Radiology (SFR). However, performing CT scan in all or many patients with suspected COVID-19 may result in radiology department overload, especially, taking into account bio-cleaning between patients. Moreover, CT scan may lead to adverse effects including induced cancer due to the cumulative diagnostic irradiation. Chest ultrasonography may be an alternative to CT scan. It is a simple, non-invasive, non-irradiating, inexpensive and available at the point of care (POCUS). Most of emergency physicians and many other specialists (pneumologists, infectious disease or intensive care physicians) are trained to perform chest POCUS and use it in their everyday practice. Multiple studies have demonstrated its superiority to chest X-ray for the detection of pneumonia. In ARDS, a scoring has been developed and has shown good correlation with mortality. POCUS is very effective in detecting peripheral patterns and seems appropriate to explore COVID-19 patients. Previous studies suggest its interest in SARSCov2 infections for initial patient assessment and identification of lung damage. However, its performances have never been scientifically evaluated to date. Our main hypothesis is that point of care lung ultrasonography performed during the initial examination may identify high-risk COVID-19 patients.
Description: To assess, in patients with confirmed or probable SARS-CoV-2 infection, chest ultrasonography capacity, using the POCUS score for ARDS, to identify patients with unfavourable outcome at D14. Unfavourable outcome is defined by intubation with mechanical ventilation requirement or death (Stage ≥ 6 on "Ordinal Scale for Clinical Improvement" of the World Health Organization) within 14 days of inclusion. We will determine the 95% confidence interval of the AUC of the ROC curve and consider POCUS capacity as clinically relevant if the lower limit of the 95% confidence interval is at least 0.7.Measure: Risk of unfavourable outcome at D14 Time: 14 days
Description: To evaluate, in patients with a confirmed or probable SARS-CoV-2 infection, whether POCUS score performances vary as a function of time, between D1 and D14, and, if so, until which time horizon its performances are clinically relevant. In this purpose, we will determine the time period for which the lower limit of the 95% confidence interval of the AUC of the POCUS score ROC curve is at least 0.7.Measure: Risk of unfavourable outcome over time Time: 14 days
Description: To identify the threshold values of POCUS score to perform risk-stratification in three groups of patients: low-risk patients, intermediate-risk patients, high-risk patients. In this purpose, we will determine two threshold values on the inflection points of the ROC curve: maximizing the specificity for a sensitivity of at least 95%, maximizing the sensitivity for a specificity of at least 95%.Measure: Risk-stratification threshold values Time: 14 days
Description: To study the impact of adding the result of POCUS evaluation to several risk-stratification clinical rules for pulmonary infection or sepsis: qSOFA, CRB 65 and CURB 65 In this purpose, we will attribute 0, 1 or 2 points to POCUS score according to the predefined threshold values and will assess : sensitivities of qSOFA with and without addition of POCUS score result, specificities of qSOFA with and without addition of POCUS score result; sensitivities of CRB 65 with and without addition of POCUS score result, specificities of CRB 65 with and without addition of POCUS score result; sensitivities of CRB 65 with and without addition of POCUS score result, specificities of CRB 65 with and without addition of POCUS score result.Measure: Adding value of POCUS score to previous risk-stratification clinical rules Time: 14 days
Description: To assess, the capacity of POCUS score at D0 to predict patient clinical status at D14 In this purpose, we will determine the correlation coefficient between the POCUS score at D0 and the clinical status of patients at day 14 according to the WHO Ordinal Scale for Clinical Improvement for COVID-19 patients.Measure: POCUS score and patient clinical status at D14 Time: 14 days
Description: To study the correlation between POCUS and CT scan assessment of lung damage. In this purpose, we will determine the intra-class correlation coefficient between POCUS assessment according to the number of affected areas among 12 and CT scan assessment according to the quantification proposed by the French Society of Radiology: 0 - normal; 1 - minor (< 10%), 2 - moderate (10-25%), 3 - important (25-50%), 4 - severe (50-75%), 5 - critical (> 75%)Measure: POCUS and CT scan correlation Time: 14 days
Description: To compare the diagnostic performances of POCUS with that of chest computed tomography to identify patients with unfavourable outcome. In this purpose, we will compare the AUC of the ROC curves of POCUS score and CT scan quantification of lung damage to identify patients with unfavourable outcome (intubation and mechanical ventilation requirement or death)Measure: POCUS versus CT scan risk-stratification performances Time: 14 days
Description: To evaluate, in the subgroup of hospitalized patients having a second chest ultrasonography at Day 5 +/- 3 of inclusion, the performances of the evolution of the POCUS score between the first and the second assessment to identify patients with unfavourable outcome. In this purpose, we will calculate the delta between the first and second POCUS score and determine the AUC of the ROC curve and its 95% confidence interval.Measure: POCUS score evolution performances Time: 14 days

An HTML report was created for each of the unique drugs, MeSH, and HPO terms associated with COVID-19 clinical trials. Each report contains a list of either the drug, the MeSH terms, or the HPO terms. All of the terms in a category are displayed on the left-hand side of the report to enable easy navigation, and the reports contain a list of correlated drugs, MeSH, and HPO terms. Further, all reports contain the details of the clinical trials in which the term is referenced. Every clinical trial report shows the mapped HPO and MeSH terms, which are also hyperlinked. Related HPO terms, with their associated genes, protein mutations, and SNPs are also referenced in the report.Drug Reports MeSH Reports HPO Reports
