Filter by:Many patients with Coronavirus Disease 2019 (COVID-19) have atypical blood clots. These blood clots can occur in either veins or arteries and be large, like in stroke or heart attack, or very tiny, called microthrombi. Some patients with COVID-19 even have blood clots despite being on anti-clotting medications. Blood with increased viscosity does not flow through the body normally, in the same way that syrup, a highly viscous liquid, and water, a minimally viscous liquid, flow differently. The researchers believe that hyperviscosity may contribute to blood clots and organ damage seen in patients with severe COVID-19. Plasma exchange removes a patient's plasma, which contains the large sticky factors that the researchers believe are increasing viscosity, and replaces it with plasma from healthy donors. In addition to providing important information about plasma exchange as a treatment in COVID-19 for patients, this study will provide data to justify resource and staffing decisions. This study will enroll 20 participants who are critically ill from COVID-19. Participants will be randomized to receive therapeutic plasma exchange (TPE) or standard of care (SOC).
This is a randomized, double-blind, placebo-controlled, phase I clinical study to evaluate the tolerability, safety, pharmacokinetic profile and immunogenicity of JS016 (anti-SARS-CoV-2 monoclonal antibody) injection in Chinese healthy subjects after intravenous infusion of single dose.Eligible patients will be injection JS016 (anti-SARS-CoV-2 monoclonal antibody)
During the current pandemic, in Italy the majority of asymptomatic or pauci-symptomatic COVID-19 cases were not identified nor diagnosed and this fact caused a decrease in the effectiveness of the various containment measures implemented. Therefore, in a future scenario where a new viral swarm is expected, the early identification of all infected cases becomes essential to plan and activate a containment strategy for the spread of the virus, given the current absence of vaccines. The typical radiological finding of COVID-19 is an interstitial pneumonia, which can be responsible, in a significant portion of patients, of an acute respiratory distress syndrome (ARDS). Low-dose chest CT and simple blood tests could identify sub-solid pulmonary nodules (SSNs) indicative of COVID-19 infection in asymptomatic subjects. Objectives of this observational study are the early detection of COVID-19 markers indicative of prior exposure or persisting viral infection in asymptomatic subjects and the assessment of the frequency and outcome of COVID-19-related SSNs in asymptomatic subjects by time, domicile, and other individual risk factors. SMILE lung CT screening program cohort has been considered, based on 960 subjects at high lung cancer risk for tobacco smoking (≥20 pack/year) and age (50-75 years), together with inflammatory and respiratory profile. SMILE utilizes a top technology dual-source CT scanner (Somatom Force) with the lowest radiation dose ever applied to lung screening. All chest CT images from screening subjects will be re-evaluated by two additional CAD programs, specifically designed for the analysis of SSNs and quantification of the total volume of lung parenchyma showing an increased density. This re-evaluation will improve the sensitivity and specificity of radiomic assessment. This study cohort, enriched by the already established longitudinal biobank of frozen plasma samples, represent an ideal opportunity to assess the frequency of SSNs in asymptomatic subjects, due to the effect of COVID-19, particularly among subjects living in areas at high risk of viral exposure. It will also be possible to evaluate if COVID-19-related SSNs are associated with chronic co-morbidity, other individual risk factors, inflammatory (CRP) / immunomodulatory (25(OH)D) blood profile, and/or can be traced by immune markers such as IgM/IgG and other cytokines. Clinical data will be integrated with an analysis of the IgG-IgM profile specific for covid-19, on the plasma samples taken at the time of the CT scan, or subsequently, in collaboration with University of Milan, Luigi Devoto Work Clinic. The lasting collaboration with the Radiological Science Department of the University of Parma in lung screening also offers the opportunity to validate the results obtained in this cohort on chest CT performed at the University Parma Hospital during the last two months in symptomatic subjects for suspected covid-19 pneumonia. In collaboration with University of Milano Bicocca, Machine Learning (ML) tools will be applied to predict the clinical relevance, severity and ultimate outcome of SSNs, based on radiomic CT features, epidemiologic risk, co-morbidity and inflammatory/immune blood biomarkers. ML analysis will generate a predictive algorithm for clinical outcome of SSNs, and specifically the risk of COV-I9 infection and unfavorable disease prognosis.
Hospital mortality attributed to SARS-CoV-2 in France increased daily by 28% in the week before confinement. The week following this decision, the daily increase was 30%. During the week of the second week of confinement, it started a decline of 19% estimated over the last 5 days, reaching the cumulative number of 2606 deaths on 29/3 (site https://www.eficiens.com/coronavirus- personal statistics / and calculation). The diagnosis of viral carriage by RT-PCR is reserved for symptomatic cases among caregivers, due to the shortage of available tests and the cumbersome implementation. The carrier diagnosis is the benchmark, on which are implemented the therapeutic strategies and established the national statistics. It can present false negatives, linked to a research too early or too late in relation to the infection, or to a technical defect of the nasal swab sample. Caregivers on the front line in patient care, in hospitals or in the city, have only partial access to this diagnostic test, depending on the existence of symptoms. The implementation of a systematic serological screening, planned by the government and which cannot be based only on the search for the virus, will make it possible to inform the caregivers presenting symptoms or not, of their serological status, and therefore of their degree immunity or, on the contrary, susceptibility to infectious contacts. It should therefore be very voluntarily requested. On the occasion of this screening, the constitution of the COVID-3S cohort will make it possible to verify the degree of contamination in an asymptomatic population, information which is sorely lacking for the estimation of the immune coverage of the population. The implementation of the Covid-3S study will be based on the work of the National Reference Center of Pr B Lina, from the COVID-SER cohort, for the selection of the most efficient test (s). It seems useful to initiate the constitution of this cohort as soon as possible in relation to the evolution of the epidemic. Pending receipt of official recommendations, the lack of knowledge of the performance of serological tests means that it should be applied first to health professionals, better able to appreciate its limits, for the initial period before determining a validated serological screening strategy. Once the strategy has been specified, the gradual expansion of screening to the patient population will provide a more representative basis for the construction of epidemiological models for evaluating strategies.
The investigating group aims at performing an observational, prospective study that involves the evaluation of circulating biomarkers predictive of clinical evolution in patients suffering from COVID-19 disease. In particular, the aim will be to verify whether there are transcripts or cytokines / chemokines in peripheral blood, modulated differently in patients with COVID-19, distinguished on the basis of the evolution towards more severe clinical pictures that require patient intubation or that show signs of cardiovascular damage. The study will be based on the transcriptional analysis of the entire genome and serum protein to evaluate the expression of a broad spectrum of cytokines and chemokines. Genome analysis will allow the genotype to be correlated to the identified gene expression profiles.
The aim of the study was to assess the inflammatory status at the presumed peak of the inflammatory phase in non-critically ill patients requiring admission for COVID-19. Patients admitted with COVID-19 from March 27th to May 3rd, 2020 were prospectively enrolled. All patients had an initial chest CT-scan for diagnosis on admission and a second chest CT-scan for follow-up concomitant with a FDG PET/CT between day 6 and day 14 after the onset of symptoms.
The aim is to demonstrate a decrease in complications among ambulatory patients who are diagnosed with mild COVID-19 by treating them with nitazoxanide for 7 to 14 days on top of standard care compared to patients who receive standard care and placebo only.
This is a bicentric, phase 2, randomized, open-label study to evaluate the efficacy and safety of maraviroc associated with standard treatment in hospitalized patients with pulmonary SARS-CoV-2 infection (COVID-19).
Note that this is a study that is co-sponsored by Medecins Sans Frontieres, Spain, and the University of Oxford. The primary objective of this study is to identify clinical and biochemical prognostic markers in adults with virologically confirmed COVID-19 who do not require oxygen supplementation, with a focus on: aiding safe discharge from a healthcare facility (i.e. a high NPV); near-term impact on COVID-19 interventions in resource-limited settings (i.e. simple clinico-demographic variables and biochemical markers for which near-patient / POCTs are commercially available or in late-stage development). The secondary objective of this study is to evaluate the field-based performance of near-patient lateral flow assays for suPAR and IL-6 in adults with non-severe SARS-CoV-2 infection
This protocol tests the safety and efficacy of a novel universal vaccine concept called "allo-priming" which is designed to protect elderly adults from progression of any type of viral infection, including possible protection against progression of the current outbreak of COVID-19 infection, and any future variants, strains, mutations of the causative SARS-CoV-2 virus as well as protection from any future currently unknown newly emergent novel viruses.
