Abstract:
Protracted bacterial bronchitis (PBB) is a common cause of children chronic cough,especially in those aged 1 ～ 6 years.It is defined by the presence of persistent wet cough for longer than 4 weeks,but lacks of symptoms or signs of other alternative diagnosis of chronic cough.It shows a normal or near-normal chest radiograph,a intense neutrophilia in bronchoalveolar lavage fluid(BALF),and a chronic purulent bronchitis under bronchochoscopy,and usually resolves after two-week course of appropriate oral antibiotic (usually amoxicillin-clavulanatc).So far,PBB hasn't been fully recognized by most pediatricians,and often been unrecognised or misdiagnosed as asthma.In this paper,pathogenesis,diagnosis and treatment are reviewed.
