结缔组织病(CTD)是自身免疫引起的全身性多脏器炎症性疾患。因此,在其发病过程中,除可累及皮肤、关节、肌肉、肾脏和心脏外,还可引起多种肺部病变。本文对CTD肺部病变发病机理、临床表现和治疗作一综述,以引起临床医师的重视。【各种CID引起的肺胸膜病变】肺内富有血管和结缔组织,因此,它是CTD患者的易损脏器。其主要的肺胸膜病变有; 1.弥漫性间质性肺炎、肺纤维化以往文献报道,类风湿性关节炎(RA)和罹病期长的进行性全身性硬皮病(PSS)患者常有此并发症。多数病例呈现慢性经过,进而发 Connective tissue disease (CTD) is a systemic multiple organ inflammatory disorder caused by autoimmunity. Therefore, in addition to its involvement in the skin, joints, muscles, kidneys and heart during its pathogenesis, it also causes a variety of lung diseases. This article summarizes the pathogenesis, clinical manifestations and treatment of CTD pulmonary lesions in order to arouse the attention of clinicians. [Various CID-induced pulmonary pleuropathies] The lungs are rich in blood vessels and connective tissue, therefore, it is a vulnerable organ in CTD patients. Its main pulmonary pleural disease are; 1. Diffuse interstitial pneumonia, pulmonary fibrosis It has been reported in the past, rheumatoid arthritis (RA) and long duration of progressive systemic scleroderma (PSS) patients often This complication. Most cases show chronic after, and then made
