title: Compared evolution of plasma fibronectin and angiotensin-converting enzyme levels in septic ARDS.
abstract: Serum angiotensin converting enzyme (serum ACE) levels and plasma fibronectin levels were measured daily in 46 septic patients during a ten day period. Thirty-eight patients developed ARDS; 28 survived (group 1), ten died (group 2), eight patients had no features of ARDS and survived (group 3). Sequential measurements of ACE and fibronectin levels were compared and plotted against indexes of respiratory impairment: PaO2 max Qs/Qt, static compliance and VD/VA ratio. These indexes were taken as criteria of weaning from controlled ventilation. During ARDS (groups 1 and 2), serum ACE levels decreased and were closely correlated with the severity of lung injury. Persistently decreased levels after eight days were consistent with continuing injury or lack of endothelial repair. On the other hand, plasma fibronectin levels increased throughout the study in survivors (group 1 and 3) and decreased in the group with fatal ARDS only (group 2). These results indicate that serum ACE levels might be a good index of endothelial injury and repair during ARDS and fibronectin a better index for evolution of sepsis and vital prognosis.
