title: Impaired functions of normal peripheral polymorphonuclear leukocytes in cirrhotic ascitic fluid.
abstract: The function of normal polymorphonuclear cells in the ascitic fluid of 32 patients with cirrhotic ascites and 17 patients with malignant ascites was studied independently of ascitic fluid heat-labile factors. Polymorphonuclear (PMN) function was assessed by a chemiluminescence method using preopsonized zymosan as stimuli. The chemiluminescence response was higher in malignant ascitic fluid than in cirrhotic ascitic fluid (0.84 and 0.15, respectively, p < 0.001). These results were confirmed by a microbiological assessment of phagocytosis. Suppressive factors were evidenced by making ascitic fluid dilutions and using cell-free chemiluminescence measurements. Addition of malignant ascitic fluid to cirrhotic ascitic fluid showed that there is also a deficiency in supportive factors other than C3. The impaired PMN production of oxidative metabolites we observed in cirrhotic ascitic fluid can partly explain the high susceptibility of cirrhotic patients to spontaneous bacterial peritonitis independently of C3 levels.
