Intercellular adhesion molecule-1 concentration in sera of patients with acute and chronic liver disease: Relationship to disease activity and cirrhosis

Abstract

To study the influence of chronic hepatitis on intercellular adhesion molecule-1 serum concentration, we measured intercellular adhesion molecular-1 in the serum of 84 patients with chronic liver disease (17 chronic persistent hepatitis, 42 chronic active hepatitis and 25 active cirrhosis) caused by hepatitis B virus (n = 46), hepatitis C virus (n = 10) and autoimmunity (n = 28). Furthermore, 20 patients with acute viral hepatitis (16 hepatitis B virus and 4 hepatitis A virus) and 6 patients with acute drug-induced hepatitis were included. Sera from 20 healthy persons were used as control. Follow-up examinations were performed during immunosuppressive therapy in 20 patients with autoimmune chronic liver disease (13 chronic active hepatitis and 7 active cirrhosis). Intercellular adhesion molecule-1 serum concentration was significantly increased in patients with acute viral hepatitis, drug-induced hepatitis, chronic active hepatitis and active cirrhosis compared with healthy controls and with patients with chronic persistent hepatitis. Intercellular adhesion molecule-1 was also significantly increased in severe chronic active hepatitis and active cirrhosis compared with moderate chronic active hepatitis and moderate active cirrhosis. Serum concentration of intercellular adhesion molecule-1 decreased significantly in patients with autoimmune chronic liver disease after 2 mo of immunosuppression when remission was present. A close correlation between aspartate aminotransferase and intercellular adhesion molecule-1 serum levels was found. We conclude the following: (a) in chronic liver disease intercellular adhesion molecule-1 serum concentration may represent, at least in part, hepatocellular damage; and (b) intercellular adhesion molecule-1 serum level does not differentiate between chronic autoimmune and chronic viral hepatitis.
