NCT ID: NCT04893070 Completed - Covid19 Clinical Trials

Impact of SARS-CoV-2 (COVID-19) Infection, Treated in Ambulatory Care, on Long-term Quality of Life in a Parisian Military Population

COVIDAMBUCMA1
Start date: July 15, 2021
Phase:
Study type: Observational

In April 2020, a meta-analysis on the long-term sequelae of respiratory syndromes related to seasonal coronaviruses (SARS and MERS) showed a significant alteration in quality of life, with in particular a decrease in physical and emotional capacities and a deterioration of social life. An improvement of the quality of life is evidenced after 6 months but without reaching the level usually observed in healthy people. The impact of SARS-CoV-2 infection on quality of life can be explained by the persistence of pleomorphic symptoms in the medium to long term. In the military population, the majority of SARS-CoV-2 cases present minor to moderate forms of the disease. Military personnel have living conditions that differ from those of the general population, in particular because of their geographic mobility, which may be responsible for isolation from the family. This isolation can be regular (we speak of "geographical celibacy" when the soldier is posted in a geographical area far from the family unit) and/or occasional, during missions on the national territory or outside. This singularity justifies a study on the impact of SARS-CoV-2 (COVID-19) infection on the quality of life in this specific population.

NCT ID: NCT04893031 Completed - COVID-19 Clinical Trials

Effect of Tocilizumab on Intensive Care Patients With COVID-19 Pneumonia, a Retrospective Cohort Study

Start date: March 1, 2020
Phase:
Study type: Observational [Patient Registry]

Although its safety and efficacy in the COVID-19 patient population are still unclear, tocilizumab is one of treatment. Tocilizumab is a U.S. Food and Drug Administration approved IL-6 receptor antagonist widely used to treat CRS secondary to the chimeric antigen receptor T cell. In this study the investigators will evaluate the efficacy of Tocilizumab, an IL-6 antagonist administered in the early period in intensive care patients with COVID-19 pneumonia followed by hypoxic and systemic inflammation is predominant, but who do not support mechanical ventilation.

NCT ID: NCT04892888 Withdrawn - Clinical trials for Coronavirus Disease (COVID-19)

Survey of the Moderna COVID-19 Vaccine in People at High-Risk of Developing Severe COVID-19 Symptoms

Start date: August 1, 2022
Phase:
Study type: Observational

This study is a survey of the Moderna COVID-19 vaccine in Japanese people at high risk of developing severe COVID-19 symptoms. The study sponsor will not be involved in how the participants are treated but will provide instructions on how the clinics will record what happens during the study. The main aim of the study is to check for side effects of the Moderna COVID-19 vaccine in this group. This will be from the first vaccination to 28 days after the second vaccination. The number of visits to the clinic will depend on the clinic's standard practice.

NCT ID: NCT04892797 Active, not recruiting - Covid19 Clinical Trials

Understanding Immunology and Patient Outcomes of COVID-19 in Hospitalized Patients

Start date: February 3, 2021
Phase:
Study type: Observational

The adaptive immune response, consisting of antiviral T and B cells, is critical for providing protection against viruses such as SARS-CoV-2, both during an active infection and later following a subsequent exposure. They can both also potentially contribute to pathogenesis if they are overstimulated. Despite these advances in knowledge, there are still significant gaps in understanding of what constitutes a protective or immunopathologic immune response and its durability. Significant knowledge gaps also remain pertaining to the early recognition of COVID patients with increased risk of clinical deterioration who require continued hospitalization and the use of more intensive treatments designed to improve outcomes. Data from non-COVID patients with MI show that platelet surface expression of FcγRIIa, the low-affinity receptor for the Fc fragment of immunoglobulin (Ig) G, identifies patients at high and low risk of subsequent cardiovascular events. Platelet expression of FcγRIIa is increased by interferon γ20 that is significantly elevated in severe COVID-19 infections. The high prevalence of arterial thrombosis among COVID-19 patients and the central role of thrombosis in respiratory failure support the hypothesis that elevated platelet expression of FcγRIIa will identify COVID patients at increased risk of thrombotic complications and clinical deterioration. In addition to the potential role of platelet activation in thrombosis associated with COIVD-19, the endothelium may also play a significant role. The investigators hypothesize that elevated EMPs in plasma will identify patients at high risk of thrombosis and clinical deterioration. To begin to address the knowledge gaps above and obtain preliminary data for future large grant submission, the investigators propose a small, prospective, single-center cohort study that will enroll patients hospitalized for COVID-19 infection and exhibiting a range of disease severity. Biosamples will be obtained and used to study T and B cells, antibody repertoire, and durability of protective immunity, and also to quantify platelet expression of FcγRIIa and circulating EMPs, as described in the protocol.

NCT ID: NCT04892459 Completed - COVID-19 Clinical Trials

Study on Sequential Immunization of Inactivated SARS-CoV-2 Vaccine and Recombinant SARS-CoV-2 Vaccine (Ad5 Vector)

Start date: May 25, 2021
Phase: Phase 4
Study type: Interventional

This is a randomized, observer-blind, parallel-controlled study, for evaluation of safety and immunogenicity of sequential immunization of a recombinant SARS-CoV-2 vaccine (adenovirus type 5 vector) in Chinese healthy adults aged 18-59 years after the priming vaccination of inactivated vaccine. 300 healthy subjects aged 18-59 years will be recruited in this study. Of them, 200 subjects who have been vaccinated with two dose of inactive SARS-CoV-2 vaccine will be recruited and randomized at a 1:1 ratio to receive a booster dose of inactivated SARS-CoV-2 vaccine or recombinant SARS-CoV-2 Ad5 vectored vaccine at 3~6 months later. Other 100 subjects who have been vaccinated with one dose of inactivated SARS-CoV-2 vaccine will be recruited and randomized at a 1:1 ratio to receive a booster dose of inactivated SARS-CoV-2 vaccine or recombinant SARS-CoV-2 Ad5 vectored vaccine at 1~3 months later. The occurrence of adverse events within 28 days and serious adverse events within 6 months after vaccination will be observed. In addition, blood samples will be collected on day 0 before the boosting with ad5 vectored vaccine and on day 14, 28 and month 6 after the boosting. Serum antibody levels, cellular immune responses and the subgroups or germlines of the specific B cells will be analyzed. Each subject will remain in this study for approximately 6 months.
