Abstract
Serum immunoglobulins were determined in 145 consecutive patients with biopsy-proven steatosis, alcoholic hepatitis, alcoholic hepatitis with fibrosis, alcoholic hepatitis with cirrhosis, inactive cirrhosis, chronic active alcoholic hepatitis, chronic active hepatitis, primary biliary cirrhosis and nonspecific hepatitis. IgM was both a sensitive (90.5%) and specific (86.2%) marker for primary biliary cirrhosis, and mean IgM levels were higher in primary biliary cirrhosis than in other diagnostic categories (p less than 0.05). IgA levels were most commonly elevated in alcoholic liver disease (p less than 0.005). IgA detected 95% of alcoholic disease, but was poorly specific (41.1%). A trend of rising IgA with increasing severity of alcoholic injury was observed, but the differences were not significant. IgG was most commonly elevated in chronic active hepatitis and alcoholic hepatitis with cirrhosis, but the IgG values did not differ significantly from those found in other diagnostic categories. Our results substantiate assertions of a diagnostic sensitivity for elevated IgA in alcoholic liver disease and IgM in primary biliary cirrhosis. With the exception of IgM in primary biliary cirrhosis, however, serum immunoglobulins are not specific markers of liver histology.
