COVID-19 VaccineCorona Virus Infection4 more

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic presents a great challenge to global health. The first case was identified in December 2019 in Wuhan, China and since has infected nearly 100 million people and claimed almost 2 million lives worldwide. In response, the medical community and scientists have worked hard to develop effective therapies and guidelines to treat a wide range of symptoms including the use of the antiviral drug remdesivir, convalescent plasma, antibiotics, steroids, and anticoagulant therapy. To prevent the spread of the disease, multiple vaccines based on mRNA and DNA technologies that include inactivated viral components have been developed and millions of doses are currently being administered worldwide. Early analysis of data from the phase III Pfizer/BioNTech and Moderna vaccine trials suggested the vaccine was more than 90% effective in preventing the illness with a good safety profile (Polack et al., 2020). However, there are still many unknowns regarding the long-term safety of these newer vaccine technologies and the level and duration of immunogenicity. SARS-CoV-2 infection results in seroconversion and production of anti-SARS-CoV-2 antibodies. The antibodies may suppress viral replication through neutralization but might also participate in COVID-19 pathogenesis through a process termed antibody-dependent enhancement (Lu et al., 2020). Rapid progress has been made in the research of antibody response and therapy in COVID-19 patients, including characterization of the clinical features of antibody responses in different populations infected by SARS-CoV-2, treatment of COVID-19 patients with convalescent plasma and intravenous immunoglobin products, isolation and characterization of a large panel of monoclonal neutralizing antibodies and early clinical testing, as well as clinical results from several COVID-19 vaccine candidates. In this study, we plan to assess the effic of both vaccines on the healthcare workers. As healthcare workers begin to receive their first vaccination dosage, we will start looking for traces of antibodies within the blood and saliva. The data provided will help us determine the efficacy of the vaccine over a period of 1 year, identify any difference in efficacy amongst different populations (gender, age, and ethnicities) differences among vaccine types, demographics and follow-up on any potential side effects. We will collaborate with Nirmidas Biotech Inc. based in Palto Alto, California, a Stanford University spinoff on this project. Nirmidas Biotech. Inc is a young diagnostic company that have received several FDA EUA tests for COVID-19. We will perform IgG/IgM antibody detection by the NIRMIDAS MidaSpot™ COVID-19 Antibody Combo Detection Kit approved by FDA EUA for POC testing in our hospital site for qualitative antibody testing. We will then send dry blood spot and saliva to Nirmidas for the pGOLD™ COVID-19 High Accuracy IgG/IgM Assay to quantify antibody levels and avidity, both of which are important to immunity. The pGOLD assay is a novel nanotechnology assay platform capable of quantifying antibody levels and binding affinity to viruses. We collaborated recently with Nirmidas on this platform and published a joint paper in Nature Biomedical Engineering on COVID-19 Ab pGOLD assay (Liu et al., 2020). It is also capable of detecting antibodies in saliva samples and could offer a non-invasive approach to assessing antibody response for vaccination.

Immunity After COVID-19 Vaccination

Tunis Military Hospital Staff Vaccinated Against Covid 19

The purpose of the research is to evaluate kinetic after vaccination to the COVID-19 coronavirus by measurements of specific and neutralizant antibodies for spike antigenic sequences . This work will allow us to follow the efficacy and tolerance of the vaccine over a year, to evaluate the antibody profile, their kinetics, the fraction of neutralising antibodies and will also allow us to understand the attitudes to be taken to ensure the best protection for our staff

Long-term Sequelae of COVID-19 (Myalgic Encephalomyelitis): An International Cross-Sectional Study...

Myalgic Encephalomyelitis

The term recovery from COVID-19 caused by SARS-CoV-2 is unverified because the infection leaves many symptoms due to permanent effects on multiple organs; The primary objective of this research is to understand acute and chronic long COVID symptoms by asking questions detecting patient's experience especially symptoms lasting for several months which is known as chronic fatigue syndrome(Myalgic encephalitis). The study focuses on symptoms describing Myalgic encephalitis which may still affect COVID patients for several months after the infection along with making a big picture about rare symptoms that may the patient experienced during or after the infection. A secondary objective of this research is to focus on the long-term sequelae effects and comorbidities following COVID-19 vaccination.

Benefit of Expanded Surveillance of Nursing Homes During the COVID-19 Pandemic

COVID-19 Respiratory InfectionSARS-CoV-2 Infection

Residents in nursing homes for the senior citizens (NH) are at high risk for death from COVID-19. We investigated whether repeated non-mandatory RT-PCR SARS-CoV-2 surveillance of NH staff and visitors reduces COVID-19 incidence rates in NH residents and allows to reduce visiting restrictions.

Study of Sputnik V COVID-19 Vaccination in Adults in Kazakhstan

Covid19Vaccine Adverse Reaction

This study will assess the safety, reactogenicity, and immunogenicity of Gam-COVID-Vac (Sputnik V) vaccine intended to provide acquired immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing coronavirus disease 2019 (COVID-19). The vaccine contains two recombinant adenoviral vectors harbouring SARS-CoV-2 Spike gene. The vaccine will be administered intramuscularly on a 2-dose prime-boost schedule. Participants will be healthy adults aged greater than or equal to 18 years, voluntarily undergoing vaccination according to the guidelines of the Ministry of Healthcare of Kazakhstan.

COVIDHypertension2 more

Hospitalized patients with COVID-19 will be included in the study in centers around Poland. After the hospitalization, a short questionnaire will be completed, including pre-hospitalization diagnoses, pre-hospitalization medications, clinical status on admission, the course, complication and the duration of hospitalization. The questionnaire will be available in paper form and on-line.

Tocilizumab vs CRRT in Management of Cytokine Release Syndrome (CRS) in COVID-19

Covid-19SARS3 more

Some patients infected with the COVID-19 can develop uncontrolled immune response, leading to potentially life-threatening damage to lung tissue. Tocilizumab was first approved by the U.S. FDA in 2010 for rheumatoid arthritis and might now be used to treat serious COVID-19 patients with lung damage, according to China's National Health Commission updated its treatment guidelines in 7th version.Continuous Renal Replacement Therapy (CRRT) was recommended by China's National Health Commission treatment guidelines in 1st-7th version to control sever COVID-19 patients.

Observational Study of Follow-up of Hospitalized Patients Diagnosed With COVID-19 to Evaluate the...

SARS-CoV-2

The infection caused by COVID19 worldwide makes it necessary to monitor drugs administered for the treatment of patients hospitalized with SARS-CoV-2. In order to know more about the efficacy and safety of the treatments used, researchers from the Cantabrian health service have developed an observational study, in the form of an ambispective registry, in which clinical data from patients treated with the different drugs currently recommended by the Spanish Agency of Medicines and Health Products (SAMHP) and the Ministry of Health, or others that may arise, are collected and analyzed. Although the conduct of clinical trials is a priority at this time, we cannot lose the clinical experience that is currently being generated, which may allow us to improve the therapeutic strategies for future patients.
