Plasma type II phospholipase A2 levels in patients with acute pancreatitis.

摘要

Changes in the blood levels of type II phospholipase A2 (PLA2) were investigated over time in patients with acute pancreatitis from an early stage after manifestation of the disease. The serum level of type II PLA2 at the first examination and the maximum level during the course of illness were both correlated with the severity of the disease. Serum levels of type II PLA2 were significantly higher in patients with acute pancreatitis complicated by multiple organ failure (349.1 +/- 146.6 ng/ml) than in those with acute pancreatitis not complicated by multiple organ failure (66.9 +/- 50.1 ng/ml). The serum levels of type II PLA2 were also significantly higher in patients who eventually died (316.8 +/- 150.5 ng/ml) than in those who survived (148.9 +/- 167.9 ng/ml). There was a significant correlation between the serum levels of type II PLA2 and those of TNF-alpha during the course of illness (r = 0.8037, p < 0.0001). The serum levels of type II PLA2 reliably reflected the severity of acute pancreatitis even in the early stages of the disease. These results suggest that type II PLA2 may be closely involved in the pathophysiology of acute pancreatitis.
