Changing epidemiology of non-cystic fibrosis bronchiectasis
Non-cystic fibrosis bronchiectasis again becomes a major health problem due to inappropriate antibiotic use and increasing frequency of protracted bacterial bronchitis. The aim was to determine the changes in etiology of bronchiectasis. Patients who admitted to Behçet Uz Children Hospital between 2005 and 2015 (n=110) were retrospectively examined. The etiology of bronchiectasis was detected as; primary ciliary dyskinesia 26.4%, protracted bacterial bronchitis 22.8%, primary immune deficiency 11.8%, bronchiolitis obliterans 8.2%, lung disease secondary to gastro-esophageal reflux 3.7%, foreign body aspiration 2.7%, tuberculosis %2.7, congenital malformation 1.8% and asthma 1.8%, respectively. In 15.4% of cases, etiology was not identified clearly. 91% of the patients were medically treated. In ten years, the frequency of asthma and tuberculosis in etiology had decreased but primary ciliary dyskinesia and primary immune deficiency had increased. Non-cystic fibrosis bronchiectasis can be followed up for a long time with medical treatment.
