Summary
Soluble HLA Class I antigens in sera (serum-HLA Class I, s-HLA Class I) of patients with chronic hepatitis (CH) were measured with an enzyme-linked double determinant immunoassay (EDDIA). The mean titers of s-HLA Class I antigens of patients with CPH (mean±standard deviation, 2.22±1.60), CAH2A (2.24±1.65) or CAH2B (2.73±1.46) were significantly higher than that of normal subjects (0.36±0.27) (P< 0.01). The titer of s-HLA Class I correlated significantly with the level of serum glutamic pyruvic transaminase (s-GPT) (r=0.73), and weakly with serum level of β2-microglobulin (r=0.43). In patients with chronic hepatitis type B (CH-B) treated with human lymphoblastoid interferon alpha (IFNα), the titer of s-HLA Class I antigens increased. The increased level of s-HLA Class I antigens in the clinical course of chronic hepatitis may be caused by their release from necrotizing hepatocytes which have acquired the expression of HLA Class I antigens on the cell-surface membrane during viral infection.
