Pulmonary alveolar proteinosis (PAP)

fivefacts-light.svg

1

PAP is a syndrome in which surfactant in alveoli builds up slowly

2

This blocks air from entering alveoli and oxygen from passing through into the blood, which results in dyspnea

3

Although primarily affecting people 30 to 50 years old, PAP can occur at any age

4

The three main causes of PAP are autoimmune, congenital, and secondary - over 90% of people with PAP have the autoimmune form

5

In autoimmune PAP, B cells begin making a GM-CSF autoantibody that attacks GM-CSF and blocks its ability to stimulate alveolar macrophages
