Evaluation of HLA‐A, ‐B, ‐Cw, and ‐DRB1 alleles frequency in Turkish patients with nasal polyposis
Copyright policy )Evaluation of HLA‐A, ‐B, ‐Cw, and ‐DRB1 alleles frequency in Turkish patients with nasal polyposis
ObjectiveTo evaluate whether there is a relationship between HLA‐A, ‐B, ‐Cw, and ‐DRB1 alleles and developing nasal polyposis (NP).Study DesignData from 66 patients with NP were compared with data from 100 healthy randomly selected controls. Asthma, ASA (acetylsalicylic acid) triad, polyp score, and previous sinonasal surgery were also recorded.Subjects and MethodsGenotyping of the HLA‐A, ‐B, ‐Cw, and ‐DRB1 alleles were performed with polymerase chain reaction (PCR) with the sequence‐specific primer (SSP) method. Data were analyzed by using a Pearson χ2 test.ResultsThe HLA‐B*07 and ‐Cw*12 alleles were found to be significantly higher in the NP patients compared with the control group, whereas the HLA‐B*57 and HLA‐Cw*04 alleles were significantly lower (P < 0.05). The HLA‐A*24, HLA‐Cw*12, and HLA‐DRB1*04 alleles were determined to be significantly higher in the NP patients with asthma and ASA triad (P < 0.05).ConclusionsOur results show that some of the HLA alleles seem to be associated with the genetic susceptibility to develop NP in the Turkish population.
