Filter by:Coronavirus disease is of an urgent global priority. The purpose of ImmuneSense™ COVID-19 study is to evaluate the clinical performance and to provide data for clinical validation for the T-Detect™ SARS-CoV-2 (previously referred to as immunoSEQ Dx SARS-CoV-2) Assay in support of Adaptive's Emergency Use Authorization (EUA) request for T-Detect™ SARS-CoV-2 and secondary aims. This assay is intended to detect immune response to the virus that causes coronavirus disease (COVID-19), SARS-CoV-2. This is critically important because the immune system may be able to tell us important information about how our own bodies detect and respond to the disease that current tests cannot.
The aim of this effort is to study host-pathogen interaction in Egyptian patients infected with COVID-19. The investigators will perform genome-wide miRNA and transcriptome screens in the infected patients along with healthy ones for comparison. All types of cytokines play pivotal roles in immunity, including the responses to different viral infections. Therefore, The investigators will study the cytokines profile in response to that infection. By comparing miRNA and transcriptome screens along with cytokines profiles, an important molecule might be identified that could play role in the inhibition of the COVID-19 outbreak. In addition, this information will help us gaining awareness of the immune process and knowing about the genes involved in the immune response against COVID-19 with an emphasis on the expression of cytokines.
The coronavirus disease (COVID-19) epidemic represents a major therapeutic challenge. The highly contagious severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) and the long duration of the disease have led to a massive influx of patients admitted in health services and intensive care units. According to current knowledge, there are no treatments that prevent the spread of the infection, especially in exposed populations, or the disease progression to a severe form. Daily active smokers are infrequent among outpatients or hospitalized patients with COVID-19. Several arguments suggest that nicotine is responsible for this protective effect via the nicotinic acetylcholine receptor (nAChR). Nicotine may inhibit the penetration and spread of the virus and have a prophylactic effect in COVID-19 infection. However, the epidemic is progressing throughout French territory and new variants (in particular the "English B1. 1.7 variant of SARS-COV-2") much more contagious run a risk of accelerating the epidemic in the population. The anti-SARS-COV-2 vaccines recently launched (or being evaluated) represent great hope in this health crisis, but trials were only able to show their effectiveness on symptomatic forms of SARS-COV-2 infection. On the one hand, the vaccination compaign for the entire population requires many months,which leaves many unprotected subjects waiting. In addition, there is currently no evidence of a protective role of vaccines against asymptomatic forms of COVID-19 and therefore on SARS-COV-2 transmission. Finally, the nicotine patches may protect people in hight-risk areas/periods until they are vaccinated (if they accept it and are eligible for it) and in the post-vaccination weeks necessary for the effectiveness of the vaccine,which reinforces the importance of evaluating this alternative prevention strategy, in the context of the arrival of vaccines
The Multi-arm trial of Inflammatory Signal Inhibitors for COVID-19 (MATIS) study is a two-stage, open-label, randomised controlled trial assessing the efficacy of ruxolitinib (RUX) and fostamatinib (FOS) individually, compared to standard of care in the treatment of COVID-19 pneumonia. The primary outcome is the proportion of hospitalised patients progressing from mild or moderate to severe COVID-19 pneumonia. Patients are treated for 14 days and will receive follow-up assessment at 7, 14 and 28 days after the first study dose. Patients with mild or moderate COVID-19 pneumonia will be recruited. Initially, n=171 (57 per arm) patients will be recruited in Stage 1. Following interim analysis to assess the efficacy and safety of the treatments, approximately n=285 (95 per arm) will be recruited during Stage 2.
The purpose of this study is to measure immunity to the flu vaccine over time in patients who had COVID-19. Adults who have been diagnosed with COVID-19 as well as controls without COVID-19 will be invited to participate in this study.
This project will provide novel data using a large cohort of more than 3000 transplanted patients. Risk and protective factors for SARS-CoV-2 infection and COVID-19 disease severity will be identified. The proportion of patients who develop antibodies after infection will be revealed. In this way the presence of these antibodies can be evaluated as a test for prior infection. Our study additionally will demonstrate how long these antibodies remain present and whether they are protective against a new infection.
This is a phase I/II clinical trial using adoptive cell therapy with NK cells or memory T cells in patients affected by COVID-19. Severe cases with COVID-19 present a dysregulated immune system with T cell lymphopenia, specially NK cells and memory T cells, and a hyper-inflammatory state. This clinical trial proposes the use of cell therapy for the treatment of patients with worse prognosis due to SARS-CoV-2 infection (those with pneumonia and/or lymphopenia). This is an innovative and a non-pharmacological intervention.
The analysis method described in this protocol is a novel simple plausible immunological approach which is non-invasive, high throughput, real-time quantitative monitoring of metabolic activity (MA) profiles of fresh Peripheral Blood Mononuclear Cells (PBMC) in response to various reagents at different concentrations. The purpose of this study is to evaluate the T cells reactivity to SARS COV 2 immunogenic selected peptides by Metabolic Activity Method in convalesce and healthy individuals and to compare it with Antibody response (ELISA) and clinical information
Background: People who get COVID-19 have a wide range of symptoms. They also recover from COVID-19 in different ways. In this study, researchers will use survey data to describe the different ways people experience and recover from COVID-19. They will also use the data to help create future studies to understand why some people do not fully recover. Objective: To learn more about the range and timing of symptoms that people have before, during, and after COVID-19 infection. Eligibility: People ages 18 and older who can give documentation of a positive COVID-19 or antibody test. Design: Participants will be screened with a telephone interview. It will take 15 minutes. They will provide their COVID-19 test results and medical records. Participants will complete a second telephone interview. It will take 30 60 minutes. They will also take online surveys every 3 months for 3 years. The interview and surveys will ask participants about their health before they got COVID-19, what happened while they had COVID-19, and what their recovery has been like. Participants will get log-in data to take the online surveys. Completing all of the surveys the first time may take up to 3 hours. Follow-up surveys will take up to 30 minutes. Participants do not have to complete the surveys in one sitting. They will be able to save their progress and finish the surveys later. Participants may be contacted to take part in other research studies.
This pilot study will assess the safety and effectiveness of UV light treatment in hospitalized patients with COVID-19.
