血清脂氧素A4水平不能预测急性支气管炎年轻患儿后期的哮喘发生
2011/08/11
摘要
背景:在婴儿和年幼儿童中,急性支气管炎常常导致喘息,但与哮喘的关系尚不清楚。我们认为,血清脂氧素A4水平可以作为预测急性支气管炎年幼患儿后期哮喘的早期标志物。
方法:入选的69名儿童分为3组:47名年龄小于24个月的急性支气管炎患儿分为试验组(第1组);11名年龄为2~24个月的急性病毒性胃肠炎患儿为非过敏性对照组(第2组);11名年龄大于24个月、患有医生诊断的哮喘恶化患儿为哮喘对照组(第3组)。检测血细胞计数、嗜酸性粒细胞计数、血清C反应蛋白、白介素-4、白介素-5、前列腺素E2、肿瘤坏死因子-a和脂氧素A4。
结果:急性支气管炎、急性胃肠炎和哮喘患儿的平均脂氧素A4水平分别为0.043±0.028、0.054±0.015和 0.051±0.031 ng/ml。t检验显示,第1组和第2组、第1组和第3组间无显著差异(p>0.05),但第2组与第3组间存在显著差异(p=0.0392)。在最终的回归模型中,血清脂氧素A4水平与年龄、女性、白细胞计数和白介素-5水平成正相关,而与其他两组相比,哮喘患者具有较低的血清脂氧素A4水平。
结论:血清脂氧素A4不能作为急性支气管炎年轻患儿早期哮喘预测性诊断的一个标志物。

Abstract
Background. Acute bronchiolitis frequently causes wheezing in infants and young children, although its relationship to asthma remains unclear. We hypothesized that serum lipoxin A(4) levels may be used as an early predictive biomarker of subsequent asthma in young children with acute bronchiolitis.
Methods. We recruited 69 children who were divided into 3 groups: 47 children younger than 24 months with acute bronchiolitis as an experimental group (Group 1); 11 children aged 2-24 months with viral acute gastroenteritis as a non-allergic control group (Group 2); and 11 children older than 24 months with physician-diagnosed asthma exacerbations as an asthma control group (Group 3). We determined white blood cell counts, eosinophil counts, and serum levels of C-reactive protein, interleukin-4, interleukin-5, prostaglandin E(2), tumor necrosis factor-alpha, and lipoxin A(4).
Results. The mean serum levels of lipoxin A(4) in the groups with acute bronchiolitis (1), acute gastroenteritis (2), and asthma (3) were 0.0430.028, 0.0540.015, and 0.0510.031 ng/ml, respectively. When compared by t-tests, there were no significant differences between Groups 1 and 2, or Groups 1 and 3 (p0.05), despite a significant difference between Groups 2 and 3 (p=0.0392). In a final regression model, serum lipoxin A(4) levels were positively correlated with age, female gender, white blood cell counts, and interleukin-5 levels in all patients, while asthma patients had lower serum lipoxin A(4) levels compared to the other two groups.
Conclusion. Serum levels of lipoxin A(4) cannot be used as an early predictive diagnostic marker for asthma in young children with acute bronchiolitis.
