Detaljerad beskrivning
This study has conducted to find the possible links between genetic make up of ICU patients with severe Covid-19 and embolism. 13 polymorphisms and mutations that the investigators targeted are located on Factor II, Factor V, Factor XIII, MTHFR, angiotensin converting enzyme (ACE), endothelial cell protein C receptor (EPCR), and FGB. The investigators have found significant changes in the mutant allele frequencies in most of the factors.
The main workflow to study a point change on DNA sequence begins with DNA isolation from a biological material. In this case, we received blood samples in ethylenediaminetetraacetic acid (EDTA) tubes from ICU patients with severe Covid-19. The investigators hypothesis claims that genetic factors triggering thrombotic events might increase the severity of the diseases by inducing the risk of emboli.
After DNA isolation, desired loci on DNA were amplified via Polymerase Chain Reaction (PCR). Amplicons including the mutations and polymorphisms need to be purified before next generation sequencing (NGS).
The investigators analyze the data using Integrative Genomics Viewer (IGV) program and check the genetic profile (wt, het, mut). Some of the changes are meaningful by themselves while some other need to be considered as combinations. Compound heterozygosity and diagnosis for thrombophilia require cooccurrence of the changes.
To compare allelic frequencies, the investigators include the average of the data coming from more than 2000 individuals with no know thrombophilia cases. In the investigators focus cohort, the investigators have the data of 47 Covid-19 patients in ICU.

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.
Beskrivning
Inclusion Criteria:
- being tested positive for Covid-19
- ICU patients developing severe pneumonia upon Covid-19 infection
Exclusion Criteria:

Changes in allelic frequencies in predetermined loci which are known to be related with thrombosis
Tidsram: 15.03.2021- 30.04.2021
|
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.

An increase in thrombophilia cases in the study group
Tidsram: 01.05.2021- 20.05.2021
|
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.
