儿童哮喘控制和个体控制标准的治疗反应的组成部分:对PEACE研究的分析
2011/08/31
摘要
背景:哮喘的治疗旨在获得并维持对哮喘的临床控制。有关儿童哮喘控制的数据较为有限。
目的:本试验对548名未获得哮喘控制的患儿进行研究,评价与哮喘未获得很好控制(WC)有关的因素。
方法:患儿接受沙美特罗/丙酸氟替卡松(SFC;50/100 µg bd)或孟鲁司特(MON;5 mg od)治疗,采用事后分析法了解影响哮喘未获得很好控制的因素,包括患者未能达到哮喘控制标准的原因;获得哮喘总体控制的情况;个体哮喘转归的时间和综合评分;未获得哮喘很好控制的相关原因。
结果:在基线状态下,各哮喘控制标准未达标的患者比例,在β2激动剂急救治疗组为96%,呼气峰值流量(PEF)组为91%;症状组为78%;夜间觉醒组为66%。大部分患者存在1个以上的因素导致未能达到综合控制评分标准,分别有482(99%)、387(80%)和249(52%)名患儿在2项、3项和4项标准上未能达标。在SFC组和MON组,分别有166名(59%)和96名(36%)获得总体哮喘控制(P<0.001)。哮喘控制标准各组成部分达标的时间也不一致,症状达标时间最快,PEF达标时间最慢。影响哮喘未获得很好控制的因素有采用MON治疗、患者所在国家以及基线状态下的夜间觉醒,其中治疗是最为重要的影响因素。
结论:不同的哮喘转归改善比例存在差异。仅评价一个或几个哮喘转归将会高估哮喘控制水平。总体综合评分联合3个或以上标准未达标的患者比例,可能会准确反映哮喘控制水平。与SFC治疗相比,MON治疗获得哮喘较好控制的可能性小3倍。

Abstract
BACKGROUND: The aim of asthma management is to achieve and maintain clinical control. Control data for children is sparse.
OBJECTIVE: This analysis evaluated factors associated with not achieving well-controlled (WC) asthma using data from a study in 548 children with uncontrolled asthma.
METHODS: Post hoc analysis of factors affecting the probability of not achieving WC asthma in children receiving salmeterol/fluticasone propionate 50/100 µg bd (SFC) or montelukast 5 mg od (MON), included: reasons for patients failing the asthma control criteria; achievement of overall asthma control; time course of improvement in individual outcomes and composite score; factors associated with not achieving WC asthma.
RESULTS: The proportion of patients failing individual control criteria at baseline was: β(2) -agonist rescue use: 96%, peak expiratory flow (PEF): 91%, symptoms: 78%, and night-time awakenings: 66%. Most patients failed the composite control score for more than one reason with 482 (99%), 387 (80%), and 249 (52%) failing 2, 3, or 4 control criteria, respectively. Overall asthma control was achieved by 166 (59%) patients in the SFC group and 96 (36%) in the MON group (P < 0.001). Time course of control differed between individual control components with symptoms responding most rapidly and PEF most slowly. Factors significantly influencing the probability of not achieving WC asthma were treatment with MON, country, and night-time awakenings at baseline, treatment being the most important.
CONCLUSION: Different outcomes improve at different rates. Assessment of one or a few outcomes over-estimates the level of asthma control. An overall composite score in combination with the proportion of patients failing on three or more criteria seemed to most accurately reflect the level of control. Compared with SFC treatment, MON was three times less likely to result in good asthma control.
