1、儿童及成年急性穿孔性阑尾炎患者细胞因子变化与临床意义作者:梁永圣,张波涛,张道飞【摘要】目的:探讨儿童及成年急性穿孔性阑尾炎(APA)患者血清细胞因子(CKs),即肿瘤坏死因子α(TNFα)、白介素6(IL6)及白介素8(IL8)的含量变化,为临床诊治提供思路及依据。方法:25例APA患儿及20例成年患者术后即刻采集血液标本,检测以上3项CKs及白细胞计数(WBC)、C反应蛋白(CRP)水平,并测取同期来院查体的健康儿童及成年人各15例的标本作为参考值。观察记录患者(儿)的临床指标,并将以上5项指标与临床指标进行相关性分析。结果:(1)所有患者(儿)术后即刻的WBC
2、、CRP、TNFα、IL6及IL8水平均明显高于参考值(P<0.05),治疗后均明显呈不同程度回落;尽管出院前患儿组的WBC、CRP已恢复正常,但TNFα、IL6及IL8仍高于参考值,且高于成年患者(P<0.05);(2)术后患儿组的腹痛、腹胀的消退时间,体温、肠蠕动的恢复时间及住院时间均较成年患者长(P均<0.05);(3)相关性分析显示TNFα、IL6、IL8、WBC及CRP5项指标两两间呈较强的正相关性(均为r>0.80,P<0.01);术后即刻TNFα、IL6及IL8的水平与住院时间均呈负相关性(分别为r=-0.67,
3、-0.78,-0.72;P=0.035,0.029,0.032)。结论:(1)TNFα、IL6及IL148三者适用于评价APA的炎症程度,且与患者(儿)的预后有关;(2)儿童APA的CKs含量高于成年患者,可能与儿童的免疫力低下有关;(3)WBC与CRP不能作为儿童APA痊愈出院的单一标准,应适当检测CKs以协助临床决策。【关键词】急性穿孔性阑尾炎;细胞因子;儿童;成年人;临床观察[ABSTRACT]Objective:Todiscussthecontentchangesofserumcytokines(CKs),ortumornecrosisfactorα(TNFα)
