他汀类药物是否能改善激素吸入治疗患者的哮喘转归:回顾性队列研究
2012/07/06
摘要
目的:动物实验和临床试验研究了他汀类药物对哮喘的治疗作用,但结果存在分歧。本研究旨在评价当前采用他汀类药物治疗的哮喘患者哮喘相关住院是否下降。
设计:对2002-2004年密西西比医疗补助计划数据进行回顾性队列研究。
参与者:对2002年7月1日至2003年12月31日间≥18岁的哮喘患者采用ICD9 493.xx密码编号。治疗患者的索引日期为鉴定期间内的任何日期,该日期前180天内,患者至少一次使用激素吸入治疗,且对他汀类药物治疗的依从性至少达到80%的时间。以未用他汀类药物的激素吸入治疗的哮喘患者作为未治疗组。两组相互匹配,并自索引日期开始随访1年。
主要检测指标:采用条件logistic回归分析比较患者住院和急诊就诊
结果:470名治疗组患者和958名未治疗组患者入选本研究。当前他汀治疗的哮喘患者,哮喘相关住院和/或急诊就诊优势比是未治疗组患者的近一半(OR=0.55; 95% CI 0.37~0.84; P=0.0059)。与此类似,用他汀治疗的患者其哮喘相关急诊就诊优势比显著下降(OR=0.48; 95% CI 0.28~0.82); P=0.0069)。
结论:我们的结果显示,同时使用他汀类药物治疗有助于哮喘的处理。有必要进行前瞻性研究提供更多结论性证据。

Abstract
OBJECTIVES: Animal studies and clinical trials have examined the potential benefits of statins in asthma management with contradictory results. The objective of this study was to determine if asthma patients on concurrent statins are less likely to have asthma-related hospitalisations.
DESIGN: A retrospective cohort study using Mississippi Medicaid data for 2002-2004.
PARTICIPANTS: Asthma patients ≥18 years were identified using the ICD9 code 493.xx from 1 July 2002 through 31 December 2003. The index date for an exposed subject was any date within the identification period, 180 days prior to which the subject had at least one inhaled corticosteroid prescription and at least an 80% adherence rate to statins. Asthma patients on inhaled corticosteroids, but not on statins, were selected as the unexposed population. The two groups were matched and followed for 1 year beginning the index date.
MAIN OUTCOMES MEASURES: Patient outcomes in terms of hospitalisations and ER visits were compared using conditional logistic regression.
RESULTS: After matching, there were 479 exposed subjects and 958 corresponding unexposed subjects. The odds of asthma-related hospitalisation and/or emergency room (ER) visits for asthma patients on concurrent statins were almost half the odds for patients not on statins (OR=0.55; 95% CI (0.37 to 0.84); p=0.0059). Similarly, the odds of asthma-related ER visits were significantly lower for patients on statins (OR=0.48; 95% CI (0.28 to 0.82); p=0.0069).
CONCLUSION: The findings suggest beneficial effects of statins in asthma management. Further prospective investigations are required to provide more conclusive evidence.
