Clinical evaluation of autoantibodies to liver cell membrane specific antigen, liver specific lipoprotein, and Tamm-Horsfall glycoprotein in autoimmune chronic active hepatitis. 1987

S Morichika, and T Arima, and H Nagashima

An enzyme-linked immunosorbent assay was developed to detect circulating autoantibodies to three liver cell membrane surface antigens, i.e., liver cell membrane specific antigen (LCM), liver specific lipoprotein (LSP), and Tamm-Horsfall glycoprotein (THGP). In autoimmune chronic active hepatitis (autoimmune CAH), the positive rate and mean titer (normal range, less than 5.5 units) for anti-LCM were 100% and 13.5 units before corticosteroid treatment and 100% and 9.9 units during the treatment. The corresponding values for anti-LSP were 84% and 11.8 units, and 81% and 8.9 units, and those for anti-THGP were 84% and 12.3 units, and 81% and 7.9 units. In an autoimmune CAH patient, elevation of the plasma levels of autoantibodies during the treatment apparently preceded the elevation of alanine aminotransferase (ALT). However, the ALT elevation induced by transcatheter arterial embolization was not associated with the elevation of these autoantibodies in an autoimmune CAH patient with hepatocellular carcinoma. In primary biliary cirrhosis, drug-induced hepatitis, and non-hepatic immunological disorders, the production of the three autoantibodies did not directly correlate with liver cell damage. These findings suggest that the elevation of autoantibodies against LCM, LSP, and THGP can be a useful guide for the prednisolone treatment of autoimmune CAH.

D007119	Immunoblastic Lymphadenopathy	A disorder characterized by proliferation of arborizing small vessels, prominent immunoblastic proliferations and amorphous acidophilic interstitial material. Clinical manifestations include fever, sweats, weight loss, generalized lymphadenopathy and frequently hepatosplenomegaly.

D008105	Liver Cirrhosis, Biliary	FIBROSIS of the hepatic parenchyma due to obstruction of BILE flow (CHOLESTASIS) in the intrahepatic or extrahepatic bile ducts (BILE DUCTS, INTRAHEPATIC; BILE DUCTS, EXTRAHEPATIC). Primary biliary cholangitis involves the destruction of small intra-hepatic bile ducts and decreased bile secretion. Secondary biliary cholangitis is produced by prolonged obstruction of large intrahepatic or extrahepatic bile ducts from a variety of causes.

D009088	Mucoproteins	Conjugated proteins in which mucopolysaccharides are combined with proteins. The mucopolysaccharide moiety is the predominant group with the protein making up only a small percentage of the total weight.

D011506	Proteins	Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.

D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
