Background: Coronavirus disease 2019 (COVID-19) pandemic is an international public health emergency with major disruptions and devastating health consequences resulting from the associated cytokine storm syndrome. The aim of our research was to assess the inflammatory biomarkers and risk factors associated with severity of (COVID-19) patients.
Methods: A cross-sectional study was conducted and included 150 Egyptian patients with COVID-19. Patients were classified into mild, moderate, and severe according to the clinical and CT chest findings. Blood samples were collected from patients for laboratory assessment of inflammatory biomarkers.
Results: Our results showed significant negative correlation between oxygen saturation percent and serum levels of inflammatory markers. The correlations were statistically significant with IL-6, CRP, ferritin, LDH, and D-dimer which can be used as sensitive biomarkers for assessment of the risk of severity of infection in COVID 19 patients.
Conclusions: The study revealed that the risk factors associated with severity of COVID 19 infection included older age, male gender, presence of underlying chronic disease, and increased levels of inflammatory biomarkers: CRP, LDH, ferritin, IL-6, and D-dimer.
