Abstract

Clinical outcome after hepatitis B virus (HBV) exposure varies extremely from spontaneous clearance to chronic hepatitis B and often progresses to liver cirrhosis (LC) and hepatocellular carcinoma (HCC). Host genetic factor plays an important role in the regulation of immune response. This study was aimed to investigate whether HLA class II DQA1 and DQB1 gene polymorphism were associated with chronic hepatitis B infection and in the development of HBV-related LC and HCC. DQA1 and DQB1 allele polymorphism were studied in 187 patients with HBV-related liver diseases (which included 73 chronic hepatitis B, 84 LC and 30 HCC patients) and 109 controls who had spontaneously recovered from HBV infection using polymerase chain reaction amplification with sequence-specific primers. Our data suggested that DQA1*0101/2/4 [odds ratio (OR)=2.78; Pc=0.003], DQA1*0103 (OR=2.64; Pc=0.0007) and DQB1*0302/3 (OR=2.15; Pc=0.01) were associated with the protection from chronic HBV infection, whereas DQB1*0402 (OR=0.25; Pc=0.001) showed susceptible effect on chronic HBV infection. DQB1*0601 (OR=3.73; Pc=0.006) conferred protective effect from developing LC; similarly, DQB1*0302/3 (OR=5.53; Pc=0.05) and DQB1*0402 (OR=0.00; Pc=0.001) conferred protect...Continue Reading
