Investigation on the characteristics of pulmonary function in patients with acute exacerbation of bronchiectasis complicated with type 2 diabetes mellitus
Objective To explore the characteristics of pulmonary function in patients with acute exacerbation of bronchiectasis complicated with type 2 diabetes mellitus(T2DM).Methods Among 74 patients with acute exacerbation of bronchiectasis,23 patients with acute exacerbation of bronchiectasis alone were selected as group A,25 patients with acute exacerbation of bronchiectasis combined with T2DM and well-controlled blood glucose as group B,26 patients with acute exacerbation of bronchiectasis combined with T2DM and poor-controlled blood glucose as group C.The pulmonary function examination was performed on the three groups of patients,and forced vital capacity as a percentage of the predicted value(FVC%)and the ratio of forced expiratory volume in one second to forced vital capacity(FEV1/FVC)of the three groups of patients were compared.Results In group A,FVC%was(82.4504±11.4826)%,FEV1/FVC was(81.5704±12.0518)%;in group B,FVC%was(74.6760±12.5300)%,FEV1/FVC was(74.0324±11.7070)%;in group C,FVC%was(67.0315±14.0777)%and FEV1/FVC was(66.9266±11.8841)%.FVC%of group A was higher than that of group B(P<0.05).FVC%of group A was higher than that of group C(P<0.01).FVC%of group B was higher than that of group C(P<0.05).FEV1/FVC in group A was higher than that in group B(P<0.05).FEV1/FVC in group A was higher than that in group C(P<0.01).FEV1/FVC in group B was higher than that in group C(P<0.05).Conclusion Patients with T2DM have a significant impact on the pulmonary function of patients with acute exacerbation of bronchiectasis,and poor glycemic control aggravates the decline of pulmonary function in these patients.
