弥漫型泛细支气管炎(DPB)是慢性支气管炎的一种类型。其特点为慢性咳嗽、多痰、劳累性呼吸困难,胸片显示双侧小结节样阴影,常伴有充气过度。病理诊断:1)慢性炎症气道病变遍及双肺;2)慢性炎症主要发生在细小支气管和小叶中心部;3)呼吸性细支气管壁和相邻的肺泡管、肺泡为泡沫样细胞所堆积伴有淋巴细胞浸润。虽然本病的诊断一般依据其临床特征,但最近对临床诊断的 DPB 患者进行的开胸活检所得到的组织病理学研究证实:临床上诊断的 DPB病例不仅包括病理上的 DPB,而且还有未分类的细支气管炎和细支气管扩张症。弥漫性泛细支气管炎与阻塞性肺部疾病一样是一种下呼吸道的慢性感染性疾病。尽管有众多种类的抗菌素用于它的治疗,但
Diffuse panbronchiolitis (DPB) is a type of chronic bronchitis. It is characterized by chronic cough, phlegm, exertional dyspnea, chest X-ray showed bilateral nodular shadows, often accompanied by over-inflated. Pathological diagnosis: 1) chronic inflammatory airway disease throughout the lungs; 2) chronic inflammation occurs mainly in the bronchioles and lobular center; 3) respiratory bronchioles wall and adjacent to the alveolar tube, alveoli are foam-like accumulation of companion Have lymphocyte infiltration. Although the diagnosis of this disease is generally based on its clinical features, recent histopathological studies of open-chest biopsy of clinically diagnosed DPB patients confirm that clinically diagnosed cases of DPB include not only pathological DPB but also Classification of bronchiolitis and bronchiolitis. Diffuse panbronchiolitis, like obstructive pulmonary disease, is a chronic, infectious disease of the lower respiratory tract. Although a large variety of antibiotics are used in its treatment,
