Learn About Diffuse Panbronchiolitis

What is the definition of Diffuse Panbronchiolitis?
Diffuse panbronchiolitis (DPB) is a rare condition characterized by inflammation of the small airways of the lungs (bronchiolitis) and chronic sinusitis. It mainly occurs among the Japanese but has been reported in other populations. Symptoms typically develop anywhere from the teenage years to the fifth decade of life and are slowly progressive. Common symptoms include chronic sinusitis, a productive cough (producing mucus), breathlessness with exertion, wheezing, and weight loss (especially as symptoms worsen). The exact cause of DPB is not known, but a variety of genetic, environmental, and systemic factors appear to contribute to the condition.
