Hereditary pulmonary alveolar proteinosis
MONDO:0012580Congenital pulmonary alveolar proteinosis is a very rare primary interstitial lung disease due to pulmonary surfactant accumulation within the alveolar macrophages and alveoli, characterized by a variable clinical course ranging from an asymptomatic clinical presentation and spontaneous remission, to symptoms such as dyspnea and cough, or to severe respiratory failure.
Also known as: congenital PAP, congenital pulmonary alveolar proteinosis, hereditary pulmonary alveolar proteinosis, inborn error of pulmonary surfactant metabolism, inborn error of surfactant metabolism, pulmonary alveolar proteinosis, congenital, sufactant metabolism dysfunction, pulmonary

New breath test could replace painful lung scopes
Knowledge-focused ENROLLING_BY_INVITATIONThis study aims to see if a simple, non-invasive breathing test can accurately measure the acidity (pH) in the airways, which is often abnormal in lung diseases. Researchers will compare results from this breath test with standard methods in 150 healthy volunteers and people with…

Brain scans reveal hidden links between body diseases and metabolism
Knowledge-focused OngoingThis study watches 200 people with lung, gut, or hormone diseases over time using special brain scans (PET). It aims to see how these diseases change brain activity and whether those changes can predict tumor return, spread, or survival. No new treatment is tested—just observatio…

Rare disease study pulled before starting: scientists sought clues in cell stress
Knowledge-focused TerminatedThis study was planned to learn how certain rare genetic mutations disrupt protein production and cause severe diseases affecting the lungs, liver, brain, and digestion. Researchers would have used cells from patients to measure protein levels and stress responses. However, the s…
