What is Interstitial lung disease? - ANSWER refers to a broad group of
inflammatory lung disorders and all of them can lead to irreversible
pulmonary fibrosis
anatomic alterations with acute stage ILD - ANSWER leads to edema,
bronchial inflammation and infiltration of WBC's in alveolar wall and
interstitial space
anatomic alterations with chronic stage ILD - ANSWER extensive
inflammation leads to pulmonary fibrosis, interstitial thickening, granulomas,
honeycombing and cavitation
what are the inorganic causes of ILD - ANSWER asbestos
silicosis
coal dust
asbestos (inorganic ILD) - ANSWER -common form of ILD
-crystal like fibers inadvertently inhaled and lead to calcium build up
-can affect 1 or both lungs
-must have history to dx but calcification in pleura helps to dx
coal dust (inorganic ILD) - ANSWER AKA-coal workers lung, black lung, coal
workers pneumoconiosis (silica found in coal is the inflammatory agent)
,-pin point black spots on lungs (coal bits)
-progresses to massive fibrosis
-nodules can get >1cm in diameter
Silicosis (inorganic ILD) - ANSWER AKA-grinders disease or quartz silicosis
silica is main component of nearly every rock on earth
Organic causes of ILD - ANSWER Hypersensivity Pneumonitis AKA allergic
alveolitis, extrinsic allergic alveolitis
These are an immune response of the lungs to an offending agent
Ex: bagassosis, farmers lung, bird breeders lung
bagassosis (organic) - ANSWER moldy sugar cane
farmers lung (organic) - ANSWER moldy hay and silage
bird breeders lung (organic) - ANSWER bird droppings/feathers
pigeon breeders lung/bird fanciers lung
common collagen vascular diseases - ANSWER Scleroderma
Rheumatoid Arthritis
Systemic Lupus Erythematosus (SLE)
Sarcoidosis
Scleroderma - ANSWER -*chronic hardening and thickening of the skin*
-causes significant scarring in the lungs
, -rare auto immune disorder
-most common women 30-50
rheumatoid arthritis - ANSWER -*inflammatory joint disease*
-pleurisy is most common pulm. complication
-ILD most common in males
systemic lupus erythematosus (SLE) - ANSWER -*multi-system disorder of
joints and skin*
-can affect kidneys, lungs, nervous system, heart
-pleurisy and pulmonary infections are common
Sarcoidosis - ANSWER -chronic unknown cause, *tubercules in eyes, lungs,
spleen liver and lymph glands*
-increase in all 3 immunoglobulins
-most common in african american women
almost like inner lungs is sloughing off
Idiopathic Interstitial Pneumonitis - ANSWER idiopathic pulmonary fibrosis
cryptogenic organizing pneumonia (COP/BOOP)
