ABSTRACT

OBJECTIVE To study the correlation between the serum-specific IgE and IL-13 single nucleotide polymorphism (SNP) among patients with allergic rhinitis who were allergic to Dermataphagoides pteronyssinus(Derp1) or Artemisia Pollen. METHODS Sixty nine patients who were allergic to Derp1 and 87 patients who were allergic to pollen were examined for detecting serum-specific IgE by a fluorescent enzyme immunoassay. The IL-13 SNP of the coding sequence (Arg130Gln) and the promoter region -1112(C/T)was measured by polymerase chain reaction /restriction fragment length polymorphism (PCR-RFLP) techniques. RESULTS Among patients who were allergic to Derp1, there was a significant correlation between the IL-13 promoter -1112(C/T)SNP ,but not of Arg130Gln ,and serum-specific IgE. Among patients who were allergic to pollen, there were no significant association both of the IL-13 promoter -1112(C/T)and Arg130Gln SNPs with serum-specific IgE. CONCLUSION The results showed a significant association of the IL-13 promoter -1112(C/T)SNP with serum-specific IgE in patients who allergic to Derp1. That suggested a possible involvement of IL-13 promoter -1112(C/T)SNP in the regulation of serum-specific IgE response to Derp1 allergens.
