Abstract

It has recently been reported that in patients with primary biliary cirrhosis (PBC), eosinophils are not only increased in the peripheral blood, but also infiltrted in the liver portal tracts. There is general agreement that eosinophils and eosinophil cationic protein (ECP) released from eosinophils contribute to cellular damage, particularly in allergic inflammation. In the present study, ECP was measured by the radioimmunoassay in sera of patients with a variety of liver diseases including PBC. Serum ECP levels were significantly higher in patients with PBC than in those with chronic viral hepatitis, in those with liver cirrhosis, and in healthy subjects. There were no significant differences in serum ECP levels between symptomatic and asymptomatic PBC. The present study suggests that high levels of serum ECP may reflect high grades of eosinophil infiltration around the septal and interlobular bile ducts characterized by chronic non-suppurative destructive cholangitis, particularly in the early stages of PBC.
