Abstract
COVID-19 is characterized by a wide range of clinical manifestations, where aging, underlying diseases, and genetic background are related to worse outcomes. In the present study, the differential expression of seven genes related to immunity, IRF9, CCL5, IFI6, TGFB1, IL1B, OAS1, and TFRC, was analyzed in individuals with COVID-19 diagnoses of different disease severities. Two-step RT-qPCR was performed to determine the relative gene expression in whole-blood samples from 160 individuals. The expression of OAS1 (p < 0.05) and IFI6 (p < 0.05) was higher in moderate hospitalized cases than in severe ones. Increased gene expression of OAS1 (OR = 0.64, CI = 0.52–0.79; p = 0.001), IRF9 (OR = 0.581, CI = 0.43–0.79; p = 0.001), and IFI6 (OR = 0.544, CI = 0.39–0.69; p < 0.001) was associated with a lower risk of requiring IMV. Moreover, TGFB1 (OR = 0.646, CI = 0.50–0.83; p = 0.001), CCL5 (OR = 0.57, CI = 0.39–0.83; p = 0.003), IRF9 (OR = 0.80, CI = 0.653–0.979; p = 0.03), and IFI6 (OR = 0.827, CI = 0.69–0.991; p = 0.039) expression was associated with patient survival. In conclusion, the relevance of OAS1, IRF9, and IFI6 in controlling the viral infection was confirmed.
