Laboratory results of blood taken at hospital admission indicated higher levels of white blood cells (p-value 3.83x10-02), total protein (p-value 2.5x10-03), creatinine (p-value 3.87x10-02), alanine aminotransferase (p-value 2.85x10-02), troponin (p-value 2.37x10-04), tumour necrosis factor α (TNFα) (p-value 1.43x10-02), IL-6 (p-value 2.78x10-03), IL-8 (p-value 2.24x10-02), IL-1β (p-value 3.78x10-02) and IL-10 (p-value 7.51x10-02) in patients with COVID-19 who died within 30 days after admission to hospital. This evidence concerns the gene IL1B and COVID-19.
