Antibody Detection in COVID-19 Cured Patients (SARS-CoV-2-CZ-Immunity)

Completed
Conditions
COVID
SARS-CoV-2
Interventions
Diagnostic Test: Quantitative analysis of anti-SARS-CoV-2-antibodies
Diagnostic Test: SARS-CoV-2 diagnostic rapid test
Registration Number
NCT04453280
Lead Sponsor
Institute of Health Information and Statistics of the Czech Republic
Brief Summary

The aim of the SARS-CoV-2-CZ-Immunity study is to determine the time profile of the presence of antibodies against SARS-CoV-2 in blood plasma by quantification of antibodies or performing a rapid test in COVID-19 cured patients.

Detailed Description

COVID-19 is caused by a new type of coronavirus called SARS-CoV-2. It is a highly infectious disease, manifested mainly by fever, respiratory problems, muscle pain, and fatigue. However, despite the publication of hundreds of papers in the literature, fundamental information about the spread and course of the disease is still lacking in COVID-19. One of such key information is the time profile of the presence of antibodies against SARS-CoV-2 after the disease.

The SARS-CoV-2-CZ-Immunity study is aiming at the determination of the time profile of the presence of antibodies against SARS-CoV-2 in blood plasma by quantification of antibodies or performing a rapid test in COVID-19 cured patients.

Primary Outcome Measures
NameTimeMethod
Determination of the concentration of anti-SARS-CoV-2 antibodies in relation to the categories of cured patients.May 2020

The primary outcome is the determination of the concentration of anti-SARS-CoV-2 antibodies IgG, IgM, and IgA classes in relation to the categories of cured patients according to the time from the date of cure from the COVID-19 disease to the date of examination.

Secondary Outcome Measures
NameTimeMethod
Determination of the concentration of anti-SARS-CoV-2 antibodies in relation to the age and to the severity of the disease.June 2020

The determination of the concentration of anti-SARS-CoV-2 antibodies IgG, IgM, and IgA classes in relation to the categories of cured patients according to their age: category 8-17, 18-39, 40-59, 60 and more years and according to the severity of the disease.

The quantification of the dependence of the change in the concentration of anti-SARS-CoV-2 antibodies.June 2020

The quantification of the dependence of the change in the concentration of anti-SARS-CoV-2 antibodies IgG, IgM, and IgA classes on the time since cure (analysis by statistical model)
