Plasma fibronectin concentrations in patients with liver diseases.
Plasma, obtained just prior to diagnostic liver biopsy in 71 patients with various liver diseases, was examined by electroimmunoassay using immunoglobulin against human fibronectin and purified plasma fibronectin as standard. The plasma fibronectin concentration was not significantly different from age- and sex-matched healthy controls in patients with chronic persistent or chronic active hepatitis (n = 7), primary biliary cirrhosis (n = 8), alcoholic fatty liver (n = 9), alcoholic hepatitis (n = 10), and alcoholic cirrhosis (n = 16). Patients with acute viral hepatitis (type A (n = 2); type B (n = 7); type non A, non B (n = 1] had significantly (P less than 0.01) raised plasma fibronectin concentrations (median 506 mg/l (range 339-804] compared to controls (median 399 mg/l (range 304-462]. Morbidly obese patients with fatty liver (n = 11) had significantly (P less than 0.001) raised plasma fibronectin concentrations (median 610 mg/l (range 429-862] compared to controls (median 361 mg/l (range 303-419].
