支气管扩张症并亚洲诺卡菌感染1例及文献回顾

诺卡菌病是由诺卡菌感染引起的局限性或播散性化脓性或肉芽肿性疾病，它主要涉及肺部、皮肤、中枢神经系统（central nervous system，CNS），其中肺部受累最常见。常见于免疫功能抑制宿主，但也可发生在免疫功能正常宿主。免疫抑制宿主更容易患播散性疾病，预后更差。诺卡菌病临床发病率低，是一种罕见病，免疫功能正常宿主患病率更低。最近，暨南大学附属广州市红十字会医院呼吸内科收治了1例支气管扩张症并肺亚洲诺卡菌感染的免疫功能正常患者，以下结合文献回顾进行报道。

A case of bronchiectasis with Nocardia asiatica infection and literaturereview

Norcardiosis is a limited or disseminatedpurulent or granulomatous disease caused by Nocardia infection, which mainlyinvolves the lungs, skin, and central nervous system (CNS), and the lungs arethe most commonly involved. It is common in immunosuppressed hosts, but canalso occur in immunocompetent hosts. Immunosuppressed hosts are more prone todisseminated the disease and have worse prognosis. As a rare disease with a lowclinical incidence, norcardiosis is even less prevalent in immunocompetenthosts. Recently, an immunocompetent patient with bronchiectasis and pulmonaryNocardia asiatica infection was admitted to Department of Respiratory Medicine,Guangzhou Red Cross Hospital, Jinan University, and is reported below with thereview of literature.
