A National Registry For Pulmonary Alveolar Proteinosis
Children's Hospital Medical Center, Cincinnati
Summary
The major goal of Part A of this study is to establish a National PAP Registry to help make reliable new research tests available to doctors to improve the diagnosis of PAP, increase awareness and knowledge of PAP, and give patients a 'seat at the table' in planning and conducting PAP research including the clinical testing of several new potential therapies. The major goal of Part B of this study is to define the natural history of autoimmune PAP (aPAP), develop a disease severity score that reflects how aPAP patients feel and function, and to develop and test novel tools to measure the severity of aPAP lung disease.

Description
PAP is a rare syndrome of surfactant accumulation and resulting hypoxemic respiratory failure that occurs in a number of diseases classified pathogenically into three groups: primary PAP (caused by disruption of GM-CSF signaling - autoimmune PAP, hereditary PAP), secondary PAP (caused by reduction in alveolar macrophage numbers and/or functions), and surfactant dysfunction-related PAP (caused by mutations in genes required for normal surfactant production). In current clinical practice, PAP is diagnosed based on a lung biopsy; an approach that is not able to identify the PAP-causing disease in…
