POLYMORPHONUCLEAR LEUKOCYTE ELASTASE (PMNE) LEVELS IN SEPSIS ；
THE EFFECT OF PMNE ON MULTIPLE ORGAN FAILURE (MOF)

To study the role of lysosomal protease released from polymorphonuclear leukocytes during MOF, plasma PMNE levels were measured serially in 38 patients. The patients were divided into two groups, 14 patients of MOF from sepsis (group 1), and 24 injured patients without MOF (group 2).
The normal value of PMNE was from 21 to 165μg/l. The PMNE levels of the group l elevated (831±241μg/l) at the time of diagnosis of sepsis and remained high during MOF. On the contrary, those of the group 2 were high on admission (574±131μg/l), but returned to normal within seven days.
There was no relationship between the levels of PMNE and the number of neutrophils. However, the PMNE/neutrophils ratio was significantly higher in group 1. Correlations were demonstrated between the amount of PMNE and the decrease in the levels of platelet counts,fibronectin and coagulation factor XIII. It is suggested that PMNE might play a major role in the pathobiochemical changes and tissue injury during MOF.
