INTRODUCTION: Aspirin hypersensitivity represents two distinct clinical syndromes, such as aspirin exacerbated respiratory disease (AERD) and aspirin-intolerant chronic urticaria/angioedema (AICU) which have different clinical phenotypes resulting from different genetic backgrounds in a Korean population. Persistent eosinophilic inflammation in airway is a characteristic feature of AERD and chemokine CC motif receptor 3 (CCR3) plays an important role in eosinophilic infiltration into the asthmatic airway.

OBJECTIVES: The main objective of this study is to investigate the association between CCR3 gene polymorphisms and aspirin hypersensitivity, including AERD and AICU.

METHODS: CCR3 mRNA expression was measured after an aspirin provocation test by real-time PCR. In total, 330 patients with aspirin hypersensitivity (191 AERD and 139 AICU) and 217 normal healthy controls (NC) were genotyped for two CCR3 promoter polymorphisms (-520T/G and -174C/T), and the functional effects of the polymorphisms were analyzed applying a luciferase reporter assay and an electrophoretic mobility shift assay.

RESULTS: CCR3 mRNA expression was significantly increased after aspirin provocation in AERD patients (P=0.002) but not in AICU patients. An in vitro functional study showed that the reporter construct having a -520G allele exhibited significantly higher promoter activity compared with the construct having a -520T allele in human myeloid (U937), lymphoid (Jurkat), and mast (HMC-1) cell lines (P<0.001). We found -520G and -174T specific bands on EMSA.

CONCLUSION: This result suggests that the CCR3 genetic polymorphisms may contribute to the development of the AERD phenotype and may be used as a genetic marker for differentiating between the two major aspirin hypersensitivity phenotypes.
