Determination of the yearly distribution of the incidence of Allergic Bronchopulmonary Aspergillosis (ABPA) in patients registered in the cystic fibrosis patient registry system of Turkey and identification of risk factors for its development

Résumé fourni par la source

Background Allergic bronchopulmonary aspergillosis (ABPA), is a hypersensitivity reaction in the lung against the antigens of Aspergillus fumigatus. The aim of this study is to determine the incidence of ABPA, and to determine the risk factors leading to the development of ABPA. Methods The study was designed as a retrospective cohort study. Using the CF Registry System of Turkey data, the incidence of ABPA was determined and the clinical and demographic characteristics of 44 patients newly diagnosed with ABPA in 2022 and 132 patients with similar mutation weight and age range without ABPA diagnosis in that year were examined and compared. Also risk factors affecting the development of ABPA were determined. Results Low pulmonary function test values, having had at least one pulmonary exacerbation in that year, receiving intravenous antibiotic treatment, using inhaled antibiotics, having high number of pulmonary exacerbations, having Pseudomonas aeruginosa colonization, having low body mass index (BMI), having cystic fibrosis related diabetes mellitus were found to be among the risk factors for the development of ABPA. Conclusions Early recognition and treatment of ABPA is essential to prevent further damage to the lungs. Patients with frequent pulmonary exacerbations, low BMI and low pulmonary function test values, chronic colonization should definitely be considered for ABPA.
