title: [Study on the association between severe chronic hepatitis B and HLA-DRB1 gene polymorphism].
abstract: OBJECTIVE
  To study the association between HLA-DRB1 gene polymorphism and severe chronic hepatitis B.
  
  
  METHODS
  26 patients with severe chronic hepatitis B were investigated for HLA-DRB1 gene polymorphism by polymerase chain reaction-sequence specific primers technique. The results were compared with those from 45 normal healthy people by use of chi2-test of Microsoft SPSS 13.0.
  
  
  RESULTS
  The frequency of HLA-DRB1 * 1301/1302 allele in severe chronic hepatitis B group was significantly higher than the frequency in the control group, while the frequencies of HLA-DRB1 * 1201/1202, 1501/1502 allele were not significantly different.
  
  
  CONCLUSIONS
  HLA-DRB1 * 1301,1302 is closely associated with the suseptibility to severe chronic hepatitis B, While HLA-DRB1 * 1201/1202, 1501/1502 have no association with severe chronic hepatitis B.
