COVID-19, Vitamin K, Severity, Mortality.


Objectives: The aim of the presented study is to evaluate the discriminative ability of vitamin K markers for predicting, monitoring, and a prognosis of severity patients of Covid -19 .

Methods: In this case-control study, a maximum of sixty patients (30–50 years old) were included. The patients' diagnoses were made using quantitative RT-PCR and a chest X-ray or CT scan performed seven to thirteen days after the onset of symptoms. Murray ratings were utilized to categorize COVID-19 patients based on the severity of their illness. (60) individuals of the same age and gender who appeared to be in good health were included in this study as a control group in order to compare the outcomes. The measurement of serum vitamin K was applied to all patients and healthy individuals.

Results: The group of COVID-19 patients had a lower serum vitamin K level (612.32 ± 106.76 vs. 1198.95 ± 151.59 ng/ml, p = 0.0001) than the healthy control group. Furthermore, we discovered a negative correlation between serum vitamin K levels and COVID-19.

Conclusion: The current findings showed that, when compared to healthy controls, patients with COVID-19 had decreased vitamin K levels, particularly in severe cases. These low levels suggest that COVID-19 patients may be more likely to die. These results imply that vitamin K may be involved in the COVID-19 disease processes.
