Some HLA alleles are known to be associated with hepatitis B virus (HBV) persistence. In order to find out the relationship between HLA and perinatal HBV infection after prophylaxis, we typed HLA classes I and II in 38 HBeAg-positive mothers, their children (19 succeeded and 19 failed in prophylaxis) and 198 HBsAg-negative healthy controls. HLA-B35 (RR=2.8, p<0.03), Cw*07 (RR=2.7, p<0.02), DRB1*07 (RR=3.6, p<0.006), DQA1*02 (RR=3.6, p<0.02) and DQB1*02 (RR=2.4, p<0.05) alleles were higher and DRB1*13 (RR=0.3, p<0.03) and DPB1*0401 (RR=0.1, p<0.01) alleles were lower frequencies in HBeAg-positive mothers than in the control. In failed children to the perinatal HBV prophylaxis, HLA-Cw*0303 allele was significantly higher (p<0.05) and DPB1*0202 allele was lower (p<0.03) than in succeeded children. These results suggest the influences of certain HLA alleles on naturally acquired chronic HBV infection may be changed by perinatal HBV prophylaxis.
