[Association of haplotype formed on HLA-DRB1 and HLA-DQA1 alleles with outcomes of hepatitis B virus infection].

Objective: To assess the association of haplotype of HLA-DRB1 and HLA-DQA1 alleles with outcomes of hepatitis B virus infection in Han population of north China.
Methods: Two hundred and seven chronic hepatitis B (HB) patients, two hundred and twelve chronic asymptomatic hepatitis B virus (HBV) carriers (HBV carrier) and one hundred and forty-eight self-limited HBV infection were investigated for HLA-DRB1 and HLA-DQA1 alleles by sequence specific-polymerase chain reaction (PCR-SSP).
Results: The frequency of DRB1*04-DQA1*0301 haplotype was 10.03% in self-limited HBV infection subjects, significantly higher than that in chronic HB patients (3.66%) (P=0.0005)ûthe frequency of DRB1*15/*16-DQA1*0102 haplotype was 6.80% in self-limited HBV infection subjects, significantly higher than 1.94% in chronic HB patients (P=0.0012) and 1.65% in asymptomatic HBV carriers (P=0.0004)ûwhile the frequency of DRB1*04-DQA1*0302 haplotype was 3.10% in chronic HB patients, higher than that in self-limited HBV infection subjects (0.39%) (P=0.0077).
Conclusion: Individuals with different haplotypes composed of HLA-DRB1 and HLA-DQA1 might have different outcomes of HBV infection.
