Previous research suggests that group IIA-secreted phospholipase A2 (sPLA2 -IIA) plays a role in and predicts lethal COVID-19 disease. The current study reanalyzed a longitudinal proteomic data set to determine the temporal relationship between levels of several members of a family of sPLA2 isoforms and the severity of COVID-19 in 214 ICU patients. The levels of six secreted PLA2 isoforms, sPLA2 -IIA, sPLA2 -V, sPLA2 -X, sPLA2 -IB, sPLA2 -IIC, and sPLA2 -XVI, increased over the first 7 ICU days in those who succumbed to the disease but attenuated over the same time period in survivors...
