[Phospholipase A2--acute phase protein after liver surgery?].

INTRODUCTION
The exact source of phospholipase A2 is unknown. In this context the liver is discussed because the secretion of phospholipase A2 could be initiated during an acute phase response.


PATIENTS AND METHODS
Three groups of patients were prospectively established: A liver resection (n = 12); B control (n = 22; oesophageal resection, gastrectomy, rectum resection); C sepsis (n = 5). Blood was collected preoperatively, each day postoperatively for seven days and at the day of discharge. Biochemical procedures: Phospholipase A2, PMN-elastase, C-reactive protein, GPT, GOT, GLDH, cholinesterase.


RESULTS
Postoperatively phospholipase A2 is unchanged in the liver resection and control group, whereas it increases significantly in septic patients. Only following liver resection GPT, GOT and GLDH increase. C-reactive protein is increased in all groups.


DISCUSSION
Unchanged phospholipase A2 after liver surgery despite an acute phase response indicated by C-reactive protein does not support the view of phospholipase A2 being of hepatic origin.
