title: Polymorphism between loci for human leukocyte antigens DR and DQ in patients with nasal polyps.
abstract: OBJECTIVE
  We explored a potential association between nasal polyps (NPs) and polymorphism at loci for human leukocyte antigen (HLA) DR and HLA-DQ.
  
  
  METHODS
  Polymorphism at loci HLA-DR and HLA-DQ were examined in 30 patients with NPs and in 81 healthy subjects by use of the polymerase chain reaction-sequence specific primer method.
  
  
  RESULTS
  HLA-DR16, HLA-DQ8, and HLA-DQ9 were found to be significantly associated with NPs. HLA-DR16, HLA-DQ8, and HLA-DQ9 specificities were found at higher frequencies in patients with NPs than in control subjects (5% versus 0.62%, RR = 8.9, p = .03; 10% versus 2.47%, RR = 4.81, p = .01; and 20% versus 6.18%, RR = 4.73%, p = .001; respectively). In contrast, HLA-DQ7 was found at lower frequencies in patients with NPs than in controls (10% versus 20.37%, RR = 0.36, p = .04).
  
  
  CONCLUSIONS
  We conclude that HLA-DR16, HLA-DQ8, and HLA-DQ9 represent potential susceptibility determinants and that HLA-DQ7 might confer resistance in nasal polyps.
