Types 1 and 2 Plasminogen Activator lnhibitor and Tirmor Necrosis Factor Alpha in Fatients with Sepsis^[*]

Summary

We have determined the plasma concentrations of types 1 and 2 of plasminogen activator inhibitor (PAI-1 and PAI-2), tumor necrosis factor (TNF-α) and endotoxin in 47 patients with bacterial infection (22 patients presented with positive blood cultures). Results were compared with those observed in 30 healthy subjects. There was a significant increase in PAI-1 and TNF-α in patients as compared to controls (p <0.0001), whereas no differences for PAI-2 were observed. PAI-1 and TNF-α were significantly higher in 18 patients with gram-negative bacteremia as compared to all other patients (p <0.0001). However, no correlation between the analyzed parameters and either endotoxin or clinical outcome was observed. We conclude that there is an increase of PAI-1 and TNF-α in patients with sepsis, which is not related to the endotoxin concentration. Our results suggest that PAI-1, but not PAI-2, is the main plasminogen activator inhibitor in human sepsis.
