OPG and BAFF as predictive biomarkers of the severity of SARS-CoV-2 infection.

ABSTRACT: Molecules of the tumour necrosis factor superfamily (TNFSF) are key players in immune regulation; an increase in some TNFSF molecules has been reported during severe COVID-19. In this study, we profiled and evaluated TNFSF members in the serum of COVID-19 vaccine-naïve patients to identify potential biomarkers associated with disease severity. Our data show that TRAIL serum levels are lower in severely affected patients than those mildly affected by COVID-19 (AUC 0.8, p = 0.0003). On the contrary, OPG and BAFF serum levels are higher in severe COVID-19 compared to mild COVID-19 cases (AUC 0.8, p = 0.0001; AUC 0.7, p = 0.0012; respectively) and moderate COVID-19 cases (OPG p < 0.01), BAFF (p < 0.05). At the transcriptional level, TRAIL, OPG and BAFF are elevated in severe compared to mild C
