基于哮喘控制测试、FEV1、呼出气一氧化氮分数和按级治疗评价开发哮喘强度表现评分(AIMS)并初步验
2012/04/06
目的:临床上,对于固有的哮喘严重程度很难进行评价。本试验旨在开发哮喘强度表现评分(AIMS),作为哮喘严重程度的一个指标。
方法:304名采用激素吸入治疗的哮喘患者完成哮喘控制测试(ACT),并检测肺活量、呼出气一氧化氮分数(FENO),记录当前的治疗。研究这些参数(ACT< 16;第一秒用力呼气容积[FEV1]<80%预测值;FENO > 50 ppb;专家组报告[EPR3]分级护理水平>3)与过去1年哮喘转归的关系,以开发AIMS,并基于随访当年的哮喘转归对其进行验证。
结果:FENO单独与前1年短效β受体激动剂(SABA)≥ 7(优势比[OR] 2.9)相关。ACT(OR 4.9)、FEV1(OR 3.3)和分级护理(OR 3.9)与过去1年全身激素(SCS)≥ 2相关。因此,所有4个参数入选AIMS(分为0~4级)。AIMS与随访当年的SABA ≥ 7、任何SCS、SCS≥ 2和急诊护理成线性相关(所有P <0.01)。与AIMS<2的患者相比,AIMS ≥2的患者在随后一年需要≥2 SCS的风险增加4倍,随后一年其他不良转归出现的风险增加2~2.8倍。
结论:AIMS与未来1年的哮喘不良转归成线性相关。有必要进一步研究AIMS作为哮喘严重程度一个指标在临床实践和临床研究中的作用。

Abstract
OBJECTIVE:Inherent asthma severity is difficult to assess clinically. The purpose of this study was to develop an Asthma Intensity Manifestations Score (AIMS) as a surrogate for asthma severity.
METHODS:Three hundred and four patients treated with inhaled corticosteroids completed the Asthma Control Test (ACT), underwent spirometry, and fractional exhaled nitric oxide (FENO) testing, and reported their current medications. These parameters (defined as ACT < 16, forced expiratory volume in 1 second [FEV(1)] < 80% predicted, FENO > 50 ppb, and Expert Panel Report [EPR3] step care level >3) were related to prior year outcomes to develop the AIMS and to follow-up year outcomes to validate it.
RESULTS:FENO was independently related to prior year short-acting beta agonist (SABA) ≥ 7 (odds ratio [OR] 2.9); ACT (OR 4.9), FEV(1) (OR 3.3), and step care (OR 3.9) were independently related to prior year systemic corticosteroid (SCS) ≥ 2. Thus, all the four items were chosen for the AIMS (0-4 points). AIMSs were linearly related to follow-up year SABA ≥ 7, any SCS, SCS ≥ 2, and emergency hospital care (all p < .01). Compared to patients with AIMSs <2, patients with AIMSs ≥2 were at more than a fourfold greater risk of requiring ≥2 SCS in the following year and were at a 2-2.8-fold greater risk of experiencing other adverse outcomes during that time period.
CONCLUSIONS:The AIMS is linearly related to future year adverse asthma outcomes. Further studies will be necessary to confirm its utility as a surrogate for asthma severity in clinical practice and clinical research.
