    摘要:

    目的 探讨呼出气一氧化氮(FeNO)检测用于评估缓解期哮喘合并缓解期过敏性鼻炎患儿病情的价值。方法 选取214 例处于临床缓解期哮喘儿童,按照有无合并过敏性鼻炎及有无进行规范化治疗分为哮喘治疗组、哮喘合并鼻炎治疗组、哮喘未治疗组及哮喘合并鼻炎未治疗组。同时记录FeNO 及引起FEV1 下降20%时的激发剂累计浓度(PC20FEV1)数值。结果 哮喘未治疗组PC20FEV1 数值高于哮喘合并鼻炎未治疗组,差异有统计学意义;两组FeNO 差异无统计学意义。哮喘治疗组与哮喘合并鼻炎治疗组FeNO 及PC20FEV1 数值差异均无统计学意义。哮喘合并鼻炎治疗组PC20FEV1 数值明显高于未治疗组,FeNO 数值明显低于未治疗组。哮喘治疗组仅FeNO 数值明显低于未治疗组,二者PC20FEV1 数值差异无统计学意义。结论 对怀疑合并有临床缓解期过敏性鼻炎的哮喘患儿进行病情评估时,FeNO 检测具有重要的价值。

    Abstract:

    Objective To evaluate the value of exhaled nitric oxide in the severity evaluation of asthmatic children with remitting rhinitis. Methods A total of 214 asthmatic children were randomly allocated to a untreated control and a conventional treatment group. Patients in each of the two subclasses were classified as asthma with concurrent rhinitis and asthma without concurrent rhinitis. Values of the 20% fall in forced expiratory volume in 1 second (PC20FEV1) and fractional exhaled nitric oxide (FeNO) were measured. Results The PC20FEV1 level was significantly higher in untreated asthma patients without rhinitis than in those with concurrent rhinitis (P<0.05), while FeNO was not significantly different between these two groups (P>0.05). There were no significant differences in both FeNO and PC20FEV1 between treated asthma patients with and without concurrent rhinitis (P>0.05). PC20FEV1 was significantly increased (P<0.05) but FeNO was significantly decreased (P<0.05) in asthma patients with concurrent rhinitis after conventional treatment. In asthmatic children without concurrent rhinitis, treatment significantly decreased the level of FeNO (P<0.05) but had not effect on PC20FEV1 (P>0.05). Conclusions Exhaled nitric oxide measurement may be useful in the severity evaluation of asthmatic children with remitting rhinitis.
