연구배경: 기관지 폐포세척액의 세포구성에 대한 분석은 미만성 간질성 폐질환에서 폐조직검사를 보완하거나 대신할 수 있는 검사방법이며 폐포염의 성격을 가장 신속하게 알 수 있고, 미만성 간질성 폐질환의 감별진단을 가능케 한다. 그러나 아직 기관지폐포세척세포에 대한 분석자료가 많지 않은 점에 착안하여 정상인의 기관지폐포세척세포와 여러 미만성 간질성 폐질환의 기관지폐포세척세포를 비교분석하여 차이를 알아보고 일차적 감별진단에 도움이 될 수 있는지를 알아보았다. 방법: 굴곡성 기관지내시경을 이용하여 정상인과 미만성 간질성 폐질환 환자의 기관지폐포세척액을 채취하여 세포를 염색하여 감별, 계수하였으며, 흡연군과 비흡연군간의 차이 및 정상군과 여러 미만성 간질성 폐질환환자의 기관지폐포세척세포의 백분율, 절대수치 및 분포의 차이를 비교분석하였다. 결과: 정상군에서 흡연군과 비흡연군간에는 세척액회수율, 총세포수, 세척액 ml당 세포수, 임파구백분율 및 임파구수, 대식세포백분율 및 대식세포수, 호중구백분율 및 호중구수, 호산구백분율 및 호산구수, FEV1(%), FVC(%)에서 유의한 차이가 없었다. 총세포수는 교원성질환, 과민성폐장염, 특발성폐섬유증, 속립성결핵에서 의미있게 증가하였고 임파구백분율은 과민성폐장염, 특발성폐섬유증, 속립성결핵에서 의미있게 증가하였으며, 대식세포는 특발성폐섬유증, 속립성결핵에서 의미있게 증가하였다. 호중구는 교원성 질환, 과민성폐장염, 특발성폐섬유증, 속립성결핵에서 그리고 호산구는 교원성 질환, 과민성폐장염, 특발성폐섬유증에서 의미있게 증가하였으며, 질환별로 폐포염의 양상을 알 수 있었으나 각 질환간의 염증세포의 빈도의 차이는 관찰되지 않았다. 결론: 굴곡성 기관지내시경을 이용한 기관지 폐포세척액의 세포구성에 대한 분석을 통해 많은 ILD 증례에서 폐포염의 존재를 알 수 있으나 ILD의 감별진단에 응용하기는 어렵다. 【Background: Analysis of cells in bronchoalveolar lavage(BAL) fluid had been used to predict the histologic changes of the bronchioles and alveoli in patients with interstitial lung diseases(ILD). Definitive diagnosis can be a1so made in some cases of ILD, such as histiocytosis. However, there are a few data of the cellular components in BAL fluid in normal Korean individuals and in patients with ILD. In order to evaluate the role of the cellular analysis of BAL fluid in prediction of alveolitis and differential diagnosis among ILDs, we compared the cellular components in BAL fluid from 50 normal individuals and 86 ILD patients. Method: BAL was performed by instillation and retrievement of normal saline with fiberoptic bronchoscopy. The cell number was counted by Hemocytometer. Differential count was done up to 500 cells on slides prepared by Diff-Quik stain and non-specific esterase stain. We compared the recovery rate(RR), cell numbers(CN), and percentages of each cellular components(CP). Results: The results were as follows: 1) There was no difference in RR, CN and CP between the normal smoker group and normal non-smoker group. 2) Total cell numbers recoverd in BAL fluid increased in collagen vascular diseases(CVD), hypersensitivity pneumonitis(HP), idiopathic pulmonary fibrosis(IPF), and miliary tuberculosis(Mil TBC) groups. 3) The percentage of lymphocytes increased in HP, IPF and Mil TBC groups. Macrophage percentages increased in HP, IPF, and Mil TBC groups. Neutrophil percentages were increased in CVD, HP, IPF and Mil TBC groups. Eosinophil percentages were increased in HP, IPF and Mil TBC groups. The numbers of each cells showed same findings as the percentages did. Conclusion: The analysis of cellular components of BAL fluid can predict the presence of alveolitis in many cases of ILDs. However, It was not helpful in differential diagnosis among ILDs.】
