About this study

Official title: Prevalence and Risk Factors of COVID-19 Infection in the Upper Silesian Agglomeration Population in 2020

Project is designed as a comprehensive population-based epidemiological study in Upper-Silesian Conurbation (Poland) aiming at:

  1. analysis of available data on incidence and mortality due to COVID-19 and
  2. estimation of the occurrence of viral infection SARS-CoV-2 as revealed by the results of serological test (ELISA: IgM, IgG), with assessment of risk factors.

The project's objectives are: to assess incidence and mortality due COVID-19 according to sex, age and coexisting diseases; to determine the level of potential "underdiagnosis" of the magnitude of COVID-19 mortality using vital statistics data for Upper-Silesian Conurbation; to assess the prevalence of SARS-CoV-2 based on the level of seropositivity in Upper-Silesian Conurbation; to identify host-related and environmental risk factors if the infection. Analysis of existing data will include monthly records on incidence and mortality over the period 01.01.2020-31.12.2020 and comparison of the findings with the monthly records of 2018 and 2019, for the same population. Cross-sectional epidemiological study will be located in three towne (Katowice, Sosnowiec, Gliwice). In each town a representative age-stratified sample of 2000 subjects will undergo questionnaire assessment and serological examination performed by serological test. The project corresponds with analogous population-based studies on COVID-19 in a number of countries and responds to the WHO recommendation in that field.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • IgM and IgG antibodies assayDiagnostic test

    5 ml venous blood sample collection to assay IgM and IgM against COVID19

Study groups in NCT04627623
Study groupRoleWhat they receive
Screened arm6000 peoples (3x2000) in all ages randomly selected from the general population of three towns (Katowice, Sosnowiec, Gliwice). From all invited is collected a venous blood samples (5ml) to assay IgM and IgG antibodies.
Receives: Diagnostic Test: IgM and IgG antibodies assay

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Estimation of prevalence of specific anti-SARS-CoV-2 IgM and IgG antibodies in general population.

    Estimation of real prevalence of elevated IgM and IgG COVID antibodies in general population will allow to estimate real number of current and past COVID infection in the population.

    Measured: 8 months

Secondary outcomes (1)
  1. Frequency of asymptomatic course of COVID in individuals with anti-SARS-CoV2 antibodies

    Prevalence of asymptomatic cases into seropositive population

    Measured: 8 months

What does the primary outcome measure?

Estimation of prevalence of specific anti-SARS-CoV-2 IgM and IgG antibodies in general population. (time frame: 8 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04627623, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
