Abstract
Serum levels of human hepatocyte growth factor (HGF) were determined in 38 patients with acute pancreatitis by an enzyme-linked immunosorbent assay. The mean value of serum HGF levels on admission in the 38 patients was 1.69 ± 0.40 (SEM) ng/ml. In 35 patients, serum HGF levels were found to be positive (>0.39 ng/ ml), with an incidence of 92.1%. In 17 patients, they were >1.0 ng/ml, which was the cutoff value for fulminant hepatic failure. Serum HGF levels in the patients with severe acute pancreatitis (2.30 ± 0.61 ng/ml; mean ± SEM) were significantly higher than those in the patients with mild and moderate acute pancreatitis (0.63 ± 0.06 ng/ml). Sixteen of seventeen patients whose serum HGF levels were >1.0 ng/ml were evaluated as severe acute pancreatitis. Serum HGF levels were significantly elevated in the patients with higher Ranson scores, higher APACHE II scores, or higher computed tomography grades. Serum HGF levels in the patients with organ dysfunction (liver, kidney, or lung) were significantly higher than those in the patients without organ dysfunction. Moreover, serum HGF levels on admission in the nonsurvivors (3.17 ± 1.30 ng/ml) were significantly higher than those in the survivors (1.22 ± 0.33 ng/ml). The mortality rate of the patients showing serum HGF levels >2.0 ng/ml on admission was 50%. In the patients with a lethal outcome, the mean serum HGF level remained constantly >2.50 ng/ml during hospitalization. The serum HGF level reflected the clinical course of the disease rapidly and distinctly. Serum HGF levels increased with complications such as organ failure, infected pancreatic necrosis, and sepsis and decreased with successful intensive and surgical treatments. These results suggest that serum human HGF levels may reflect the severity, organ dysfunction, and prognosis in acute pancreatitis.
