The role of interleukin (IL) 13 and IL-17A in aspirin-exacerbated respiratory disease (AERD) remains unknown.
To analyze the IL-13 and IL-17A gene polymorphisms in Japanese patients with AERD.
The single-nucleotide polymorphisms in each gene were examined in patients with AERD, patients with aspirin-tolerant asthma (ATA), and healthy controls.
Frequencies of the TT/CT genotype of the IL-13 -1111C>T gene were higher than frequencies of the CC genotype in AERD patients compared with ATA patients (P < .001). In female patients with AERD, frequencies of the TT/CT genotype were higher than those of the CC genotype compared with female patients with ATA (P < .001). However, genotype frequencies of IL-13 Arg110Gln did not differ between AERD and ATA patients. Frequencies of the CC genotype of the IL-17A -737C>T gene were higher than those of the TT/CT genotype in AERD patients compared with ATA patients (P = .02). In female patients with AERD, frequencies of the CC genotype were higher than those of the TT/CT genotype compared with female patients with ATA (P = .03). Forced expiratory volume in 1 second (percentage predicted) in AERD patients with the CC genotype of the IL-13 -1111C>T gene was lower than that in the patients with the TT/CT genotype. AERD patients with the TT/CT genotype of the IL-17A -737C>T gene had a higher peripheral total eosinophil count compared with the patients with the CC genotype. The comparison of the clinical characteristics according to the IL-13 Arg110Gln gene polymorphism showed no difference.
These findings suggest that the IL-13 -1111C>T and IL-17A -737C>T gene sequence variations might have a role in the development of AERD.
白细胞介素(IL)13 和 IL-17A 在阿司匹林加重性呼吸系统疾病(AERD)中的作用尚不清楚。
分析日本 AERD 患者的 IL-13 和 IL-17A 基因多态性。
在 AERD 患者、阿司匹林耐受型哮喘(ATA)患者和健康对照者中,检测了每个基因的单核苷酸多态性。
与 ATA 患者相比,AERD 患者中 IL-13-1111C>T 基因 TT/CT 基因型的频率高于 CC 基因型(P<0.001)。在 AERD 女性患者中,与 ATA 女性患者相比,TT/CT 基因型的频率高于 CC 基因型(P<0.001)。然而,IL-13Arg110Gln 基因型的频率在 AERD 和 ATA 患者之间没有差异。与 ATA 患者相比,AERD 患者中 IL-17A-737C>T 基因 CC 基因型的频率高于 TT/CT 基因型(P=0.02)。在 AERD 女性患者中,与 ATA 女性患者相比,CC 基因型的频率高于 TT/CT 基因型(P=0.03)。与 TT/CT 基因型的 AERD 患者相比,IL-13-1111C>T 基因 CC 基因型的患者的 1 秒用力呼气量(百分比预计值)较低。IL-17A-737C>T 基因 TT/CT 基因型的 AERD 患者的外周血总嗜酸性粒细胞计数较高。根据 IL-13Arg110Gln 基因多态性比较临床特征,无差异。
这些发现提示 IL-13-1111C>T 和 IL-17A-737C>T 基因序列变异可能在 AERD 的发生中起作用。
