This study looks at the safety and effectiveness of different drugs in treating COVID-19 in people who have been hospitalized with the infection and who have acute respiratory failure. Participants in the study will be treated with either a study drug plus current standard of care (SOC), or with placebo plus current SOC.
This is a phase 1/2 study in adult healthy subjects that have previously been vaccinated with an FDA-authorized vaccine against COVID-19. This clinical trial is designed to assess the safety, efficacy, reactogenicity, and immunogenicity of hAd5-S-Fusion+N-ETSD formulated for subcutaneous, sublingual, and oral (capsule) administration.
Sars-Cov2 virus is transmitted through the respiratory route and by direct contact with contaminated surfaces and subsequent contact with nasal, oral or ocular mucosa. Many studies have found that the oral cavity and specifically the saliva may be a high-risk route for SARS-CoV-2 infection. Thus, strategies reducing salivary viral load could contribute to reduce the risk of transmission. Furthermore, studies have shown that SARS-CoV persists for two days in oral mucous membranes before its diffusion to the lower respiratory tract. This offers an interesting preventive and therapeutic window of opportunity for the control of this disease. In addition, Naso-pharyngeal viral load was linked with lung disease severity in a study of 12 patients with pneumonia.**. Some current studies around the world, as listed on ClinicalTrials.gov, are testing the effect of some common mouth rinses/gargles on the Covid-19 viral load, including Chlorhexidine gluconate, Hydrogen peroxide Povidone Iodine, Saline (1.102% w/v, slightly hypertonic) and Alcohol. This study aims to test whether Prolonged Hypertonic Saline Mouth Rinse would reduce/eliminate*** the viral load in the Oro- Naso-Pharyngeal cavity, and could therefore be used as a strategy to reduce transmission risk in clinical and social settings. The investigator hypothesizes that COVID-19-positive participants who use Hypertonic Saline Prolonged Rinse treatment will have an reduction/elimination of their Covid viral load, will develop a negative Covid test 7 days after intervention completion and will improve their clinical symptoms, potentially reducing lung disease severity.
The objective of this study will be to evaluate the effect of vaccination on breath VOC content. By capturing and analyzing the breath of anti-COVID-19 vaccinated subjects during the period of antibody production, the investigators will determine and quantify all the compounds associated with the body reaction to the COVID-19 antigen.
The Primary Objective of This Single-center Study is to Investigate the SARS-CoV-2 Spike Glycoprotein RBD Antibody Concentration in Saliva and Serum in Healthy Non Vaccinated and Non-SARS-CoV-2 Infected, COVID-19 Convalescents, Persons Vaccinated With Pfizer-BioNTech BNT162b2, Moderna mRNA-1273 or AstraZeneca ChAdOx1 nCov-19 AZD1222 Vaccines, and Convalescent COVID-19 Patients That Have Subsequently Been Vaccinated. A Potential Difference in the Immunoglobulin Concentrations of the Pfizer-BioNTech BNT162b2 Vaccine, Moderna mRNA-1273 vaccine and the AstraZeneca ChAdOx1-S Vaccine Will be Uncovered. This Knowledge About the Mucosal Immunity Will be Important for Further Designing of Vaccine Strategies.
The objective of the current study is to investigate the utilization of nebulized heparin to circumvent pathologic changes in COVID-19 and prevent harmful effects possible with systemic anticoagulation.
Rationale: COVID-19 is associated with severely increased morbidity and mortality in patients with chronic kidney disease stage G4-G5 and patients on dialysis or after kidney transplantation. Therefore, effective SARS-CoV-2 vaccination would be of great clinical importance in these patients. However, SARS-CoV-2 vaccination studies have excluded these patients so-far. Literature data indicate that vaccination may be less effective in these patient groups. Objective: To assess the efficacy and safety of SARS-CoV-2 vaccination in patients with chronic kidney disease stage G4-G5, patients on dialysis or after kidney transplantation during two years follow-up after vaccination. Study design: prospective single center observational cohort study. Study population: - all Dutch patients on dialysis with data registered in the Dutch Dialysis registry (RENINE) - all Dutch patients after kidney transplantation with data registered in the Dutch national kidney transplant registry (NOTR). - All Dutch patients with chronic kidney disease stage G4-G5 registered in the Santeon hospitals. Intervention: After SARS-CoV-2 vaccination according to standard of care, blood will be drawn for antibody response measurements at day 28 and month 6 after 2nd vaccination at by mailer-based finger-prick in 3400 hemodialysis patients, 600 peritoneal dialysis patients, 4000 patients after kidney transplantation and 4000 patients with chronic kidney disease stage G4-G5 Main study parameters/endpoints: The primary endpoint is efficacy of SARS-CoV-2 vaccination determined as: - the incidence of COVID-19 after vaccination. Secondary endpoints are - the antibody based immune response at 28 days after completion of vaccination. - the duration of antibody based immune response at 6 months compared to at 28 days after completion of vaccination. - mortality - adverse events of specific interest according to (inter)national authorities in collaboration with LAREB - presence of HLA-antibodies in dialysis patients on the waiting list for a first kidney transplantation - acute rejection and graft failure in patients after kidney transplantation The incidence of these endpoints will be compared, if applicable, to those: - in the general population who are vaccinated - in patients on dialysis or after kidney transplant who are not vaccinated Within these patient groups endpoints will be compared between recipients of different vaccines.
The primary objective is to measure the change between COVID-19 patients and normal subjects; the secondary objective is to measure the change in COVID-19 patients between baseline and 4-month follow up.
The COVID-19 pandemic has made severe impact worldwide for those inflicted by the disease, the caretakers, the general public, as well as the health care system. Hospitalized patients with COVID-19 experience physical isolation during treatment. Isolation may lead to psychological distress that could negatively affect well-being such as affective states of depression, anxiety, and loneliness. Thus, creative ways to deliver psycho-social support are needed when face-to-face therapy sessions may not possible. We investigated the effectiveness of video-based psychotherapy in reducing distress in patients with COVID-19 treated in a general hospital isolation ward in Jakarta. This study included 42 patients with COVID-19, who were asked to watch three brief psychotherapy videos about relaxation, managing thoughts and emotions, and mindfulness. Before and after watching the videos, patients were asked to complete the Subjective Units of Distress Scale (SUDS) to measure their stress level. 31 subjects experienced a significant decrease in SUDS score after the intervention. Our brief video-based psychotherapy intervention may have a positive effect on reducing distress in hospitalized COVID-19 patients in areas with scarce resources.
The Flavor test has been developed and validated by our group to assess retro-nasal olfactory performances. The original flavor test has been simplified, with the great advantage to be self-administrable for COVID-19 patients in isolation, without any risk to health professionals.
