摘要: The A, B, C and DR locus specificities of the human leukocyte antigens system (HLA) were determined in 45 delta-positive 44 delta-negative Italian patients, all with HBsAg-positive chronic active liver disease; controls 526 healthy blood donors matched for age, sex geographical origin. HLA-A, gene frequencies not significantly changed. In were: DR2, 37.8%; DR3, 20%; DR4, 11.1%. 13.6%; 36.4%; 0%. Control 19.4%; 17.1%; 18.5%. corrected p values differences between patients pc = 0.046; NS (not significant); NS. NS; 0.03; 0.002. These findings show that: (a) a genetic marker autoimmunity, might assist establishment HBsAg disease absence delta superinfection; (b) DR2 is linked failure to clear agent, (c) DR4 may protect from virus B persistence. Identification adventitious factors such as help uncover subgroup carriers who are genetically predisposed develop disease.
