IL-13和TNF-α在肺炎支原体肺炎儿童血清中的表达及意义

Serum levels of IL-13 and TNF-α in children with Mycoplasma pneumoniae pneumonia

摘要:

目的：观察白细胞介素13（interleukin-13,IL-13）和肿瘤坏死因子α（tumor necrosis factor alpha，TNF-α）在小儿肺炎支原体肺炎中的变化。方法:酶联免疫方法检测40例肺炎支原体肺炎伴喘息患儿、40例肺炎支原体肺炎不伴喘息患儿、其他病原菌感染肺炎40例（普通肺炎组）及40例正常对照组儿童的血清IL-13和TNF-α的浓度。结果:肺炎支原体肺炎患儿血清IL-13、TNF-α的水平高于正常对照组及普通肺炎组；肺炎支原体肺炎伴喘息患者的IL-13、TNF-α的水平分别为214.6±67.2 ng/L，0.55±0.13 ng/L，高于不伴喘息者（189.6±52.1 ng/L, 0.42±0.16 ng/mL），差异均有显著性（P<0.01）。结论：IL-13、TNF-α浓度增高可能在小儿肺炎支原体肺炎导致喘息样发作中起重要作用。［中国当代儿科杂志，2010，12（4）：275-277］

Abstract:

OBJECTIVE: To examine serum levels of interleukin-13 (IL-13) and tumor necrosis factor alpha (TNF-α) in children with Mycoplasma pneumoniae (MP) pneumonia. METHODS: Eighty children with MP pneumonia complicated by wheezing or without (n=40 each), 40 children with pneumonia from non-MP infection and 40 healthy children were enrolled. Serum levels of IL-13 and TNF-α were measured using ELISA. RESULTS: The serum levels of IL-13 and TNF-α in the MP pneumonia group were significantly higher than those in non-MP pneumonia group and the healthy control group (P<0.01). The children with MP pneumonia complicated by wheezing had increased serum levels of IL-13 (214.6±67.2 ng/L vs 189.6±52.1 ng/L; P<0.01) and TNF-α(0.55±0.13 ng/mL vs 0.42±0.16 ng/mL; P<0.01)compared with those without wheezing. CONCLUSIONS: The increase in serum levels of IL-13 and TNF-α may play important roles in the pathogenesis of MP pneumonia and wheezing attack in children.［Chin J Contemp Pediatr, 2010, 12 (4):275-277］
