Urine Cytokines as biomarkers in COVID-19 Patients

Introduction COVID‐19 pandemic has been one of the main global health concerns in 2020, and many aspects of the disease remain enigmatic. While some patients infected with the disease‐causing virus SARS‐CoV2 have no or mild symptoms, others experience severe symptoms requiring hospitalization. Of these more severe patients, some remain stable while others experience cytokine storm syndrome or an exaggerated immune response that has been correlated with disease severity and progression of acute respiratory deterioration. It is currently unknown why some patients with COVID‐19 demonstrate this response and others do not. In light of the apparent prominent role of the inflammatory mediators (i.e. cytokines) in COVID‐19 pathogenesis, the ability to identify screening tools not only for the SARS‐CoV2 virus but also for cytokines is important. The present investigation was designed to identify the urinary cytokine signature in COVID‐19 patients.
