月经前哮喘与月经周期白三烯的变化
2011/12/26
摘要
背景:一些报道显示,对于存在月经前严重哮喘的女性,月经前期白三烯C4水平存在增加,这表明可采用抗白三烯治疗。
目的:分析白三烯在月经前哮喘中的作用。
方法:对育龄期女性哮喘患者整个月经周期的呼吸道症状和峰值流量进行问卷调查,这些哮喘患者分为有和无月经前哮喘患者。月经前哮喘(PMA)定义为与排卵前期相比,月经前期哮喘存在临床和功能性恶化(≥20%)。取血检测排卵前和月经前白三烯C4的水平。
结果:收集62名哮喘女性患者血样,其中34名(54.3%)满足PMA标准,月经前恶化为20~40%。PMA患者(1.50 ng/mL vs. 1.31 ng/mL; p=0.32)和非PMA患者(1.40 ng/mL vs. 1.29 ng/mL; p=0.62)排卵前和月经前的白三烯C4水平无显著差异。PMA患者和非PMA患者间白三烯水平也未存在显著性差异。各哮喘严重程度患者间也无显著差异。
结论:结果显示,白三烯C4并未参与月经前哮喘的致病,或者并不支持采用抗白三烯的特异性疗法来治疗月经前哮喘,至少是中度月经前哮喘。各严重程度哮喘间白三烯水平也无显著差异。

Abstract
BACKGROUND: Several authors have reported an increase in leukotriene C4 in the premenstrual phase in women with severe premenstrual asthma, indicating that antileukotrienes could be used in treatment.
OBJECTIVE: To analyse the role of leukotrienes in premenstrual asthma.
METHODS: A questionnaire on respiratory symptoms and peak flow during one complete menstrual cycle was given to women of fertile age to define them as asthmatics who suffered from premenstrual asthma or not. Premenstrual asthma (PMA) was defined as a clinical or functional deterioration (≥20%) in the premenstrual phase compared with the preovulatory phase. Blood samples to measure leukotriene C4 were taken during the preovulatory and premenstrual phases.
RESULTS: Blood samples were taken in 62 asthmatic women, 34 of whom (54.3%) presented PMA criteria, all with a premenstrual deterioration of between 20 and 40%. There was no difference in leukotriene C4 levels between the preovulatory and premenstrual phases in the women who suffered from PMA (1.50ng/mL vs. 1.31ng/mL; p=0.32) and those who did not (1.40ng/mL vs. 1.29ng/mL; p=0.62). Neither were there any differences in leukotriene levels between women with or without PMA. The results were similar for each category of asthma severity.
CONCLUSIONS: Our data show that leukotriene C4 does not appear to be involved in the pathogenesis of premenstrual asthma, or support the use of anti-leukotrienes in the specific treatment of premenstrual asthma, at least in women with a moderate premenstrual deterioration. No differences appeared in any of the categories of asthma severity.
