VARIATION IN HEPATIC ESTROGEN-RECEPTOR CONCENTRATIONS IN PATIENTS WITH LIVER-DISEASE - A MULTIVARIATE-ANALYSIS

Hepatic estrogen receptor concentrations were measured in liver biopsy specimens from 102 patients (58 women and 44 men) with liver disease and correlated to several clinical, biochemical, and histologic background variables by means of multiple regression analysis. Half of the tissue was processed for histologic evaluation with a semiquantitative registration of histologic characteristics, whereas the other part was used for receptor analysis by enzyme immunoassay. Fifteen patients with no or minimal histologic changes served as controls. The analysis shows that the reduced estrogen receptor concentrations observed in patients with chronic liver diseases reflect the degree of liver dysfunction and not the specific type of liver disease. Serum albumin, log serum bilirubin, log serum alkaline phosphatases, and the degree of parenchymal fibrosis were significantly related to hepatic estrogen receptor level in the final regression model, but only part of the variation can be explained by these variables, and other factors must be of importance.
