The CPAnet registry established in 2018 is an international multicenter collaboration aiming to improve CPA knowledge and patient care. In 2020, it has been awarded a Clinical Research Collaboration (CRC) by the ERS. This study’s aim was to describe the data collection process and content of CPAnet registry, by presenting preliminary clinical data.Methods: In the CPAnet registry, clinical data are collected through a web-based questionnaire. Data include CPA phenotype, comorbidities, treatment, outcome and follow-up from several international centers. An exemplary descriptive analysis was performed on 74 patients, who were registered online before April 2020.Results: CPA patients were predominantly (72%) male, 39% had chronic obstructive pulmonary disease and 68% had a history of smoking. Chronic cavitary pulmonary aspergillosis was the most common CPA subtype (62%). In 32 patients (52%), voriconazole was the preferred first-line therapy.Conclusion: The multicenter multinational CPAnet registry is a valuable approach to gather comprehensive data on a large study population and reflects real-world clinical practice rather than focusing on specific patient populations in more specialized centers. Additional CPA reference centers are being encouraged to join this promising CRC.* The 2 first (EVB and LVA) and 2 last authors (CBL and JRD) contributed equally.FootnotesCite this article as: European Respiratory Journal 2020; 56: Suppl. 64, 4929.This abstract was presented at the 2020 ERS International Congress, in session “Respiratory viruses in the "pre COVID-19" era”.This is an ERS International Congress abstract.
