Brief 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.
