Abstract

There are conflicting data to date on the causal relationship between idiopathic interstitial pneumonia and antineutrophil cytoplasmic antibody (ANCA): (1) myeloperoxidase-ANCA may play a pathogenetic role in pulmonary fibrosis, or (2) pulmonary fibrosis may induce production of the antibody. In this article, we describe a case of an elderly female patient with microscopic polyangiitis that developed after positive conversion of myeloperoxidase-ANCA during the course of idiopathic interstitial pneumonia. Our experience as well as similar case reports may suggest that idiopathic interstitial pneumonia may induce production of ANCAs and even ANCA-associated vasculitis.

摘要

目前关于特发性间质性肺炎与抗中性粒细胞胞浆抗体(ANCA)之间的因果关系存在相互矛盾的数据:(1)髓过氧化物酶-ANCA可能在肺纤维化中起致病作用,或者(2)肺纤维化可能诱导抗体产生。在本文中,我们描述了一例老年女性患者,在特发性间质性肺炎病程中髓过氧化物酶-ANCA转为阳性后发生了显微镜下多血管炎。我们的经验以及类似的病例报告可能提示,特发性间质性肺炎可能诱导ANCA产生,甚至引发ANCA相关性血管炎。
