Objective
To analyze the association of human leucocyte antigen (HLA)-DRB and -DQB alleles with Ealesprime; disease, and to investigate the potential immunogenetics mechanism of Ealesprime; disease.
Methods
Gene loci of HLA-DRB and -DQB1 alleles were detected by polymerase chain reaction-sequence specific primer (PCR-SSP) in 27 Han-nationality patients with Ealesprime; disease in Northern China and 30 age and sex-matched normal persons as control, then statistics package for social science (SPSS) for Windows ver 13.0 software was used to analyze the distribution features of frequency of HLA-DRB and -DQB1 alleles in the two groups.
Results
Compared with the control group, the frequency of HLA-DRB104 allele increased obviously in the patients with Ealesprime; disease［odds ratio (OR)=3.20 ，OR 95% confidence interval（CI）=1.00-10.21, and P=0.047］. Simultaneously, no statistically significant difference of the distribution of any other DRB or DQB1 allele between the two groups was found (Pgt;0.05).
Conclusions
In hannationality people in Northern China, DRB104 is positively associated with Ealesprime; disease, suggesting that DRB104 may confer a major influence on Ealesprime; disease. Turbulence of immune function begotten by infect-agents attack may occur in the individuals with Ealesprime; disease due to the specific hereditary diathesis of HLA, which may cause the occurrence and development of Eales disease.
