Primary Biliary Cirrhosis Associated with HLA—DRw3

Abstract
Twenty‐one unrelated Caucasian patients with Primary Biliary Cirrhosis were typed for HLA—A, B, C and HLA‐DRw antigens. The antigens HLA‐A1, HLA‐B8 and HLA‐DRw3 were found in increased frequency in relation to the control group. When the P values were corrected for the number of antigens tested only the increase of HLA—DRw4 remained significantly different from the control group (P corr. < 0.004). The antigen HLA—DRw3 was carried by 12 out of 21 patients (57.1%) in comparison to 11 out of 74 (14.8%) normal unrelated Caucasian subjects.
