Objective  To analyse the clinical characteristics of allergic bronchopulmonary aspergillosis (ABPA). Methods  The clinical data of 26 patients diagnosed as ABPA from September 2016 to February 2018 in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. Results  Among 26 patients with ABPA, 15 were female, 11 were male, with a mean age of (47.6±11.7) years. Before the diagnosis of ABPA, 13 cases had been misdiagnosed as bronchial asthma, 8 as bronchiectasis, 8 as pulmonary infection, 3 as tuberculosis. All patients had cough, sputum production, wheeze in 2, fever in 5, hemoptysis in 4, chest pain in 4, dyspnea in 2. The wheezing sound were heard in 20 patients and wet rales were heard in 4 cases. All patients had increased total IgE level ［median 5 000 (654 – 5 337)IU/ml］. The eosinophil counts were increased in 23 patients ［median 0.99 (0.50 – 3.69)×10⁹/L］ and percentages of peripheral blood eosinophil were elevated to (0.36±0.10). Skin prink test was positive in 10 cases. All patients had increased Aspergillus fumigatus specific IgE ［median 15.1 (0.4 – 29.6)kU/L). Chest X-ray showed fleeting consolidation. Chest CT showed multiple pachy, central cylindrical bronchiectasis, mucous plugging, band linear or glover-finger opacities. Sixteen cases underwent bronchoscopy, out of them 5 cases underwent transbronchial lung biopsy, 2 cases underwent CT guided percutaneous lung biopsy. Fourteen cases were treated with oral corticosteroids combined with antifungal therapy. Conclusions  ABPA is a relatively rare and without specific clinical manifestations. In the early period, it is mostly misdiagnosed as bronchial asthma, so it is necessary to improve the early diagosis of ABPA and give appropriate treatment. Regular follow-up should be made to prevent the recurrence.
