摘要
目的 探讨5岁以下喘息儿童鼻咽分泌物(NPS)和血清中白细胞介素(IL)-17水平在喘息评估中的临床意义.方法 将53例5岁以下反复喘息患儿,分为有特应性体质组(喘息Ⅰ组,27例)和非特应性体质组(喘息Ⅱ组,26例);并从同期住院治疗的疝气、肾结石等非感染性疾病术前患儿中随机抽取20例作为对照组.分别收集NPS和血清,经处理后用双抗体夹心酶联免疫吸附(ELISA)法检测IL-17水平.结果 喘息Ⅰ、Ⅱ组血清和NPS中IL-17水平分别为(1469.32±978.30)、(1473.70±974.35)ng/L和(263.34±131.80)、(788.28±132.40)ng/L,明显高于对照组的(36.48±2.00)、(36.45±5.00)ng/L(P<0.01),其中喘息Ⅰ组血清和NPS中IL-17水平高于喘息Ⅱ组(P<0.05);NPS和血清中IL-17呈正相关(r=0.313,P<0.05).结论 检测NPS中IL-17可以作为识别5岁以下有发展为哮喘倾向的喘息儿童的指标,并给予早期临床干预和治疗.
Objective To explore the clinical significance of interleukin (IL)- 17 in nasopharyngeal secretions (NPS) and serum of wheezing children under 5 years old. Methods Fifty-three children with recurrent wheezing under 5 years old were divided into wheezing group Ⅰ (with atopic high risks,27 cases)and wheezing group Ⅱ (without atopic high risks, 26 cases) ;20 children without infectious diseases such as hernia and renal calculus were enrolled as control group. After collecting and dealing their NPS and serum,the levels of IL-17 were measured by double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). Results The levels of IL-17 in serum and NPS in wheezing group Ⅰ [(1469.32 ± 978.30),(1473.70 ±974.35) ng/L],and wheezing group Ⅱ [(263.34 ± 131.80), (788.28±132.40) ng/L] were significantly higher than those in control group [(36.48 ± 2.00), (36.45 ± 5.00) ng/L] (P 〈 0.01 ), and the levels of IL- 17 in wheezing group Ⅰ were higher than those in wheezing group Ⅱ (P 〈 0.05 ); the expression of IL- 17 in NPS and serum had a positive correlation (r = 0.313,P 〈 0.05). Conclusion The detections of IL-17 in NPS can be used as laboratory index to distinguish wheezing children who have a tendency to persistent wheezing, and early intervention and treatment should be given.
