In a study conducted on 56 patients with COVID-19 and 49 control patients with other respiratory diseases, it was found that the levels of cytokines/chemokines (IL-6, CXCL-10, HGF) and some lipid metabolites (TxB2, 11-HETE, 9-HODE, 13-HODE, 5-HETE, 12-HETE, 15-HETE, 14S-HDHA, 17S-HDHA, and 5-oxo ETE) were significantly elevated in patients compared to the controls. This evidence concerns the gene HGF and COVID-19.
