The study of the broncho-alveolar lavage (BAL) has been carried out in 15 consecutive (13 B27) ankylosing spondylarthritis (AS), compared to 17 test subjects. There is no modification of the number of cells, of the percentage of lymphocytes, of the CD4/CD8 ratio, of the beta-2-microglobulin or the conversion enzyme in the BAL liquid between the AS group and the test group. The IgA level of the BAL is lower and the IgA deposits in the bronchial mucosa are more frequent in the AS group (but not in a significant way). Unlike other inflammatory diseases, it seems that there is no subclinical alveolitis in the course of AS.
对15例连续的（其中13例B27阳性）强直性脊柱炎（AS）患者进行了支气管肺泡灌洗（BAL）研究，并与17名测试对象进行了比较。AS组和测试组之间，BAL液中的细胞数量、淋巴细胞百分比、CD4/CD8比值、β2-微球蛋白或转化酶均无变化。AS组BAL的IgA水平较低，支气管黏膜中IgA沉积更常见（但差异无统计学意义）。与其他炎症性疾病不同，AS病程中似乎不存在亚临床肺泡炎。
