[Plasma proteins in the early postoperative course after liver transplantation]

The levels of fibronectin, alpha-1 antitrypsin, and fibrinogen have been studied in 34 patients after orthotopic liver transplantation (OLT). Patients were grouped according to A: postoperative course without complications (n = 18), B: development of sepsis accompanied by organ insufficiency (n = 8), and C: acute rejection (n = 6). The plasma levels of alpha-1 antitrypsin and fibrinogen did not show a typical pattern with respect to the postoperative course. The levels of fibronectin, however, did respond to the postoperative events. Starting from a subnormal level a significant increase was observed in group A (p less than 0.005) and C (p less than 0.05) whereas in group B plasma levels remained low. Significant differences (p less than 0.05) were found on day 3 and 5 between group A and C and group B and C. At the end of the observation period survivors (group A and C) had significantly higher levels of fibronectin than nonsurvivors (group B). Therefore fibronectin might aid to diagnose immunologic disturbances after OLT.
