Filter by:Prospective study for clinical performance evaluation of COVID-19 diagnostic tests: detection of anti-SARS-CoV-2 antibodies by RDTs or ELISA (manual or automated), rapid diagnostic tests based on antigen detection, molecular or proteomic testing of SARS-CoV-2 (sensitivity, specificity, predictive values)
A randomized parallel double-blinded placebo-controlled clinical trial to evaluate the effect of Emtricitabine/Tenofovir alafenamide (FTC/TAF) compared with placebo on the risk of developing SARS-CoV-2 disease (COVID-19) in healthcare workers with high transmission risk in addition to currently recommended control measures.
This study is to evaluate the utility of the PCL Rapid Antigen Test for Coronavirus (COVID-19) in a real world clinical setting. The PCL test has completed laboratory validation and holds a European CE marking for in vitro diagnostic devices. These tests have been made available to South West Pathology Services as a donation in kind by iPP (Integrated Pathology Partnership). They have been widely used in South Korea. This study will test the practical delivery of the test in terms of time constraints and error rates. We will also compare the objective performance to the current standard diagnostic test for COVID-19 and against a proven serological antibody test when a suitable reference testing becomes available. We will recruit patients having a SARS CoV-2 PCR swab test and ask for consent to test them with the PCL antigen test in parallel. We aim to study 200 patients split across three sites; Musgrove Park Hospital, Basildon University Hospital and Southend University Hospital. The results will not be used to guide clinical decision making. Patients having a COVID PCR test will be asked to read the patient information sheet and asked if they would like to participate. The patients will be asked to have a second nasal/throat swab taken shortly after their swab for the PCR test. Written informed consent will be taken for whole blood or plasma left over from any routine clinical sample to be stored as anonymised samples for future testing once a reference test becomes available. We will report results of the onsite clinical diagnostic test and the PCL antigen test with the number of the kit used, and test date. Anonymised information about year of birth, gender and place of testing will be collected alongside date of onset, symptoms and immunodeficiency status or significant conditions.
Doctors are at high risk of corona virus infection (COVID-19) during pandemic. The investigators are aiming to explore the emotions, perceived stressors, knowledge and coping strategies of doctors who are working during COVID-19 pandemic in different specialties and in different hospitals by a self assessment questionnaire that was designed and modified from two previously published articles (mentioned in the references), including 7 sections with 88 questions.
The current pandemic caused by the newly identified coronavirus responsible for COVID-19 is a major threat to our populations and societies. Hypothesis/Objective The acquisition of protective immunity at the level of the individual, either through vaccination or natural resolution of the infection, progressively leads at the level of the population to the reduction of the fraction of the population that can be productively infected and transmit the virus, hence, leading to the diminution of the rate of transmission, a phenomenon called herd immunity. Herd immunity was proposed as a strategy to control the infection. However, it remains difficult to model group immunity given the limited knowledge of the interaction between the host immune system with the virus, whose capacity to evolve in face of a neutralizing response is also not known. It is therefore important to acquire a better knowledge of the immunological memory that ensures the resolution of COVID-19 after SARS-CoV2 infection. Method To study single-cell B and T memory cells specific for the anti-SARS-CoV-2 response and characterize somatic mutations of immunoglobulin genes and TCR, in hospitalized and symptomatic patients and in patients cured of SARS-CoV-2.
Currently, due to the effects of COVID-19 pandemic, there is an imperative need to change the healthcare model. In this regard, telemedicine has proved very useful in health crises, in which there is a possibility of infection between people, offering remote access to medical care. Telemedicine has been used in many chronic diseases such as asthma and chronic obstructive pulmonary disease, diabetes mellitus, and appears to be well accepted by patients. However, few studies have been conducted in surgical services and in other diseases. Therefore, the aim of this study is to assess the level of acceptance of the patients, in this pandemic situation, to a telemedicine follow-up in different departments. This is an observational, cross-sectional, multicenter and international study with prospective and retrospective data collection. To evaluate patients' acceptance, we used the validated questionnaire Telehealth usability questionnaire (TUQ). In addition, all patients will provide an overall satisfaction score for telemedicine on a scale from 1 to 5 (1=lowest; 5=highest satisfaction).
The primary objective of this study is determine the safety and efficacy of ACT-20-MSC (allogenic human umbilical derived mesenchymal stem cells) and ACT-20-CM (allogenic human umbilical derived mesenchymal stem cells in conditioned media) in patients with moderate to severe COVID-19 pneumonia.
This study is a phase I /II adaptive clinical trial to evaluate the safety, tolerability and the Immunogenicity of Ad5-nCoV in healthy adults from 18 to <55 and 65 to <85 years of age，with the randomized, observer-blind, dose-escalation design
SARS-CoV-2 transmission is frequently occurring in hospital settings, with numerous reported cases of nosocomial transmission highlighting the vulnerability of healthcare workers. If products proved to be efficacious against COVID-19, why are so many HCW getting COVID-19? Is it related to experience? Is it generated by the exhaustive job? Is there any degree of relationship to stress? These questions are still without fully correct answers. Achieving global benefits for HCW is still waiting.
This study is a prospective, phase II, multi-center, randomized, double-blind, placebo-controlled trial to evaluate the efficacy and safety of mavrilimumab in hospitalized patients with acute respiratory failure requiring oxygen supplementation in COVID- 19 pneumonia and a hyper-inflammatory status. The study will randomize patients to mavrilimumab or placebo, in addition to standard of care per local practice. The total trial duration will be 12 weeks after single mavrilimumab or placebo dose.
