Insights
Hereditary thrombotic factors like Factor II G20210A and Beta-fibrinogen G-455A were more common in COVID-19 patients. Factor V Leiden mutation was linked to increased D-dimer levels, indicating a potential role in disease severity.
Area of Science:
- Medical Genetics
- Hematology
- Infectious Diseases
Background:
- Coronavirus disease 2019 (COVID-19) is a multi-systemic infectious disease with significant public health implications.
- Understanding factors influencing COVID-19's chronic and systemic course is crucial for patient management.
Purpose of the Study:
- To investigate the association between hereditary thrombotic factors and the clinical course of COVID-19.
- To explore the role of specific genetic mutations in COVID-19 severity and related biomarkers.
Main Methods:
- Analysis of five polymorphic loci (Factor V Leiden, FII G20210A, Beta-fibrinogen G-455A, MTHFR C677T, MTHFR A1298C) in COVID-19 patients using multiplex PCR.
- Classification of patients based on clinical disease severity (severe vs. mild).
Main Results:
- Significantly higher frequencies of FII G20210A and Beta-fibrinogen G-455A genotypes were observed in the study group compared to literature data.
- Factor V Leiden (FVL) wildtype genotype was associated with lower D-dimer levels, while the GA genotype increased D-dimer levels 2.55-fold.
- Beta-fibrinogen G-455G genotype was more prevalent in patients with elevated lactate dehydrogenase (LDH) levels (>250 U/L).
Conclusions:
- While no direct correlation was found between the five thrombotic mutations and overall COVID-19 severity, FII G20210A and Beta-fibrinogen G-455A mutations were notably frequent.
- The increased carrier frequency of FII G20210A and Beta-fibrinogen G-455A mutations in COVID-19 patients warrants further investigation with larger cohorts.
- The FVL mutation's association with elevated D-dimer levels suggests a potential role in thrombotic risk stratification for COVID-19 patients.
Objective:
Coronavirus disease 2019 (COVID-19) has rapidly spread worldwide and presents critical challenges for public health. Due to its chronic and systemic course, COVID-19 is currently accepted as a multi-systemic infectious disease. Here we explore the possible association between disease course and hereditary thrombotic factors and comorbidities.
Patients And Methods:
The patients admitted to the COVID-19 center in the Istanbul Faculty of Medicine were recruited for the study. The patients were classified according to the clinical course, severe vs. mild. Five polymorphic loci were analyzed by multiplex PCR: Factor V Leiden (FVL), FII G20210A, Beta-fibrinogen G-455A, and methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C.
Results:
FII G20210A and Beta-fibrinogen G-455A genotypes were significantly higher in the study group compared to the literature. Wildtype genotype (GG) in Factor V Leiden locus was significantly associated with low D-Dimer levels (p =0.013). The GA genotype increased the D-Dimer levels 2.55-times compared to the GG genotype (p =0.003). Moreover, the Beta-fibrinogen G-455G genotype was significantly higher in the LDH>250 group (p =0.046).
Conclusions:
The presence of solid tumors in patients with COVID-19 was related to the severity of the disease course. No evidence of a correlation between the severity of the disease and all five thrombotic mutations was found, whereas the FII G20210A and Beta-fibrinogen G-455A mutations were significantly high compared to previously reported Turkish population data and global carrier rates. This finding will need to be verified by further studies with larger samples since it may reflect a likelihood of having the COVID-19 disease. The high carrier frequency of FVL mutation was more likely present in the D-dimer high group generating an increase in the D-dimer levels 2.55-times compared to the wildtype.
