A study of endotoxaemia in patients with primary biliary cirrhosis.
Hepatic reticuloendothelial function may be diminished in patients with primary biliary cirrhosis. Endotoxin concentrations in peripheral blood and in the superior mesenteric vein were measured, by the beta-glucan sensitive, factor-free, endotoxin-specific limulus assay, in patients with primary biliary cirrhosis and liver cirrhosis (non-PBC cirrhosis). Endotoxaemia was detected in the peripheral blood of seven out of nine patients (78%) with asymptomatic primary biliary cirrhosis, but in only two out of thirteen patients (15%) with non-PBC cirrhosis. The endotoxin level was significantly higher in the earlier stages of primary biliary cirrhosis than in the later stages (P < 0.05). The endotoxin level in superior mesenteric vein blood was significantly lower in patients with primary biliary cirrhosis than in patients with non-PBC cirrhosis. Peripheral endotoxaemia in patients with primary biliary cirrhosis may be due to the diminished capacity of the hepatic reticuloendothelial system, for phagocytosis of endotoxin.
