Opsonophagocytic dysfunction in patients with liver cirrhosis and low responses to tumor necrosis factor-alpha and lipopolysaccharide in patients' blood.

To evaluate their defense level against bacterial infection of patients with liver cirrhosis, we compared the luminol-dependent chemiluminescence (CL) response of peripheral blood from 40 patients with that from 40 healthy volunteers. Small quantities of heparinized whole blood (100 microl; final dilution, 1:10) were used for phagocytes, and CL was measured on addition of nonopsonized zymosan or Escherichia coli without special opsonization. Whole blood CL in cirrhotic patients was significantly lower than that in the healthy controls.
