초록

목적: 기도과민성은 천식의 대표적인 증상이지만, 경과에 대해서는 잘 알려져 있지 않다. 본 연구에서는 경증 천식 환자들에서 기도과민성의 호전 빈도를 확인하고, 임상 지표들과의 관련성을 알아보고자 하였다. 방법: 천식을 진단받고 약물치료 중 3개월 이상 천식 관련 증상이 없었던 환자를 대상으로 하였다. 기도과민성 호전 여부를 확인하기 위하여 메타콜린 기관지유발 검사를 이용하였고, 메타콜린 유발농도 25 mg/mL에서도 FEV1 수치가 20% 이상 감소하지 않았을 때 기도 과민성 음성으로 정의하였다. 기도 과민성 음성 전환군과 양성 유지군 사이의 임상적 특징을 확인하기 위하여 각종 임상 지표들을 후향적으로 조사하였다. 결과: 총 54명의 환자들 중에서 22명(40.7%)이 기도과민성이 음성으로 전환되었다. 기도 과민성이 양성으로 유지되는 인자로는 남성, 처음 진단 당시 호흡곤란 증상, 고용량 흡입용 스테로이드 및 지속형 기관지 확장제의 사용 여부였고, 연령, 호흡곤란 이외의 증상, 각종 혈액검사 소견, 폐기능검사 결과, 천식 진단 당시의 진단 방법, 천식 진단과 기도과민성 측정 간의 시간 간격 등은 양 군 간의 차이가 없었다. 다변량 분석에서는 남성 이외의 인자는 양 군 간의 차이가 없었다(p = 0.014). 결론: 경증 천식환자들 중 약 40%는 추적 메타콜린 기관 지유발 검사에서 기도과민성이 음성으로 전환되어 임상적 관해를 보였다. 경증 천식 환자에서 기도과민성이 호전 여부를 예측하기 어렵기 때문에 기도과민성을 재평가하여 천식 조절제 지속 여부를 확인할 필요가 있다.

Background/Aims: Airway hyperresponsiveness (AHR) is one of the typical characteristics of asthma. However, its natural course is unknown. The presence of AHR is often not assessed in asthmatics undergoing medical treatment. We investigated the changes of AHR as compared with clinical parameters in patients with mild asthma. Methods: We enrolled patients who were diagnosed with asthma, but were asymptomatic for > 3 months while undergoing medical treatment. AHR was measured using a methacholine bronchial provocation test after a 2-week washout period. AHR-negativity was defined as a $PC_{20}$ > 25 mg/mL. Clinical parameters were retrospectively compared between the AHR-negative and -positive patients. Results: Among 54 patients, 22 (40.7%) were AHR negative. Factors associated with the maintenance of AHR were male sex, presence of dyspnea, and high-dose inhaled corticosteroid plus long-acting beta agonists at initial presentation (respectively, p < 0.05). Age, symptoms other than dyspnea, blood tests, results of spirometry, diagnostic methods at presentation, and time from diagnosis to follow-up testing were not significantly different between AHR-negative and AHR-positive patients. Multivariate analyses failed to show a significant difference between the two groups, except for male sex (p = 0.014). Conclusions: Approximately 40% of patients with mild asthma show no AHR or clinical remission of the disease. Male sex may be a predictive factor for persistent AHR. However, altered AHR status is not predictable in patients with mild asthma undergoing medical treatment. Therefore, the cessation of regular controller might be advocated, and reassessment of AHR should be mandatory.
