Brief Summary

Covid-19 outbreak has caused death of millions of people because of not only the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection itself but also infection dependent complications. Abnormalities in thrombotic events leads to some of these complications which eventually result in emboli. The endothelial damage caused by the virus interacting with ACE2 on the host cells leads to the activation of coagulation cascade. Accumulation of byproducts of the cascade might have some roles in embolism inducing risk of organ damage, other life-threatening problems, and even death. To enlighten the factors triggering embolism, the investigators have focused on genetic changes such as polymorphisms and mutations in certain genes in DNA samples coming from intensive care unit (ICU) patients.

Outcome Measures

Primary Outcomes (2)

  • Changes in allelic frequencies in predetermined loci which are known to be related with thrombosis

    In the first 28 samples the investigators received, we expected a predictive result revealing the genetic background and embolism in Covid-19. Deviations from allelic frequencies of healthy population regarding some of the factors will support the hypothesis of the study.

    15.03.2021- 30.04.2021

  • An increase in thrombophilia cases in the study group

    Thrombophilia is a complex state with the contribution of several factors. Clinical picture and the mutations enable the diagnosis. With an expanded study group consisting of 47 patients, we determined the patients with thrombophilia.

    01.05.2021- 20.05.2021

Study Arms (2)

ICU patients with severe COVID-19 pneumonia

Without using any intervention, this group has been included in the study to research certain genetic dispositions determining the severity of the COVID-19 pneumonia

Random population

This group has been included as a control group to compare the genetic predisposition of ICU patients with severe COVID-19 pneumonia with the normal population.

Eligibility Criteria

Age18 Years - 95 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Groups were assigned to determine the genetic factors that explain severity of COVID-19 infections. These genetic factors play role in thrombotic events in the body. Case group involves ICU patients with emboli that suffer from severe COVID-19. The investigators expect to see some deviations from normal population regarding the mutations and polymorphisms related to thrombophilia. Control group is normal population representing the normal allelic frequencies of the determinant genetic factors.

You may qualify if:

  • being tested positive for Covid-19
  • ICU patients developing severe pneumonia upon Covid-19 infection

You may not qualify if:

  • previously tested positive for genetic factors increasing thrombosis risk
  • ICU patients developing severe emboli regardless of Covid-19 infection
