Abstract

In order to see if the term of "plasma cell hepatitis", dating back to the early sixties, is still valid as a morphological diagnosis for autoimmune chronic hepatitis (AICH), and to find out if the existence of several subgroups is reflected by histopathology, we investigated 26 patients with chronic hepatitis, who met the criteria of autoimmune hepatitis based on tests for antinuclear, anti-smooth muscle antibodies (SMA) and on immunoassays for liver-kidney-microsomal (LKM) antigen, liver membrane antigen (LMA), and soluble liver antigen (SLA). In our material autoimmune hepatitis represent the entire spectrum of chronic hepatitis with variable inflammatory activity ranging from chronic persistent hepatitis to severe inflammatory lesions in chronic active hepatitis with transition to cirrhosis. When compared to viral chronic hepatitis A and non-A, non-B, however, characteristic features can be evaluated consisting in broad hypocellular areas of collapse and microacinar transformation of hepatocytes with hydropic swelling being the predominant type of cell lesion. Eosinophilic clumping and acidophilic necrosis were insignificant. Plasma cells were not a constituent feature of AICH. From this histopathologic pattern it may be co...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Autoimmune hepatitis formerly called lupoid hepatitis, is a chronic, autoimmune disease of the liver that occurs when the body's immune system attacks liver cells causing the liver to be inflamed. Discover the latest research on autoimmune hepatitis here.
