A CPAnet consensus statement on research priorities for chronic pulmonary aspergillosis: a neglected fungal infection that requires attention.

Chronic pulmonary aspergillosis (CPA) is a severe fungal infection with a high morbidity and mortality, and is usually seen in immunocompetent patients with respiratory disorders. Clinical presentation is nonspecific and often overlaps with the symptoms and the radiological pattern caused by the underlying disease. Clinical management of CPA is further hampered by limited information about the epidemiology, disease dynamics, sensitivity and specificity of different mycological tests, mechanisms of antifungal resistance, efficient treatment and management strategies. In order to contribute to a better understanding and to improve CPA patient management and outcome, we established the Chronic Pulmonary Aspergillosis Network (CPAnet), a self-organized multinational research collaboration. Key research priorities, defined by using a modified Delphi process, include the establishment of a multinational web-based registry, the validation of different diagnostic tests, the establishment of a culture collection from samples of patients with proven CPA and the establishment of a consensus on a treatment outcome definition.
