NCT04579471

Brief Summary

This project will provide novel data using a large cohort of more than 3000 transplanted patients. Risk and protective factors for SARS-CoV-2 infection and COVID-19 disease severity will be identified. The proportion of patients who develop antibodies after infection will be revealed. In this way the presence of these antibodies can be evaluated as a test for prior infection. Our study additionally will demonstrate how long these antibodies remain present and whether they are protective against a new infection.

    Prevalence and risk-factors for SARS-CoV-2 infection

    inclusion during 4 months

  • Prevalence and risk-factors for COVID-19

    Prevalence and risk-factors for COVID-19

    inclusion during 4 months

Secondary Outcomes (1)

Study Arms (3)

Transplanted patients

All patients who underwent solid organ or hematopoietic cell transplantation at UZ Leuven

Diagnostic Test: SARS-CoV-2 IgG

Transplanted patients with past SARS-CoV-2 infection

Transplanted patients with past SARS-CoV-2 infection will be followed for one year (at month 3, 6 and 12 after the initial study visit) to assess durability of IgG positivity

Diagnostic Test: SARS-CoV-2 IgG

Transplanted patients without past SARS-CoV-2 infection

100 transplanted patients without past SARS-CoV-2 infection will be followed for one year (at month 3, 6 and 12 after the initial study visit) to assess durability of IgG positivity and as control for the transplanted patients with WITH past SARS-CoV-2 infection

Diagnostic Test: SARS-CoV-2 IgG

Interventions

SARS-CoV-2 IgGDIAGNOSTIC_TEST

Collection of clinical variables, assessment of IgG antibodies for SARS-CoV-2, plasma collection for translational immunology studies
