Restrictive lung disease table Flashcards
idiopathic pulmonary fibrosis
- age group
- associated with what?
older pts >60
assoc. w/ tobacco use
aka UIP (usual interstitial pneumonia) = IPF

- age group
- associated with what?
older pts >60
assoc. w/ tobacco use
aka UIP (usual interstitial pneumonia) = IPF
Restrictive lung diseases are typically going to present with what?
DOE
crackles
cough clubbing
What lung disease is going to have honeycombing with ground glass infiltrates?
IPF aka UIP
Nonspecific interstitial pneumonia NSIP
- age group
- prognosis?
younger females
prognosis better than IPF
What are the FEV1/FVC ratios for restrictive lung diseases?
slightly >/= 0.8
In restrictive lung disease, the FEV1 and FVC are equally reduced, thus, the FEV1/FVC ratio should be approximately normal, or slightly increased
What are the FEV1/FVC ratios for Obstructive lung diseases?
3 general causes of restrictive lung diseases
- increase in elastic/connective tissue
- increase in lung water
- increase in surface tension

younger females
prognosis better than IPF
Organizing pneumonia
- Is it infectious?
- histo pattern?
- how do you treat it?
BOOP!
Non infectious: usually idiopathic secondary to CVD, drugs, HP, aspiration
- Bilateral peripheral alveolar opacities “fuzzy nodules”
- Intraluminal plugs of granulation tissue
Very steroid responsive
What are the FEV1/FVC ratios for Obstructive lung diseases?
↓↓
Eosinophilic pneumonia:
- presentation
- treatment?
- Acute eosinophilic pneumonia
- mimics ARDS (sim. to acute interstitial pneumonia) - Chronic eosinophilic pneumonia
- more in nonsmokers and women
lots of eosinophilic infiltrates (chronic has fibrosis and macrophages)
steroid responsive
Which one is homogenous? IPD or NSIP?
NSIP - homogenous
IPF - heterogenous
smoking related interstitial lung diseases (ILD):
- respiratory bronchiolitis (RB-ILD)
- Desquamative interstitial pneumonia (DIP)
- Langerhans cell histocytosis (LCH)
What lung disease presents with accumulation of “dusty brown” macrophages?
the smoking related ILDs:
- respiratory bronchiolitis (RB-ILD)
- bronchiocentric macrophages - Desquamative interstitial pneumonia (DIP)
- macrophages filling distal airspaces
What pathogen is most common in:
community acquired pneumonia, -give typical vs atypical ones.
hospital acquired pneumonia?
community acquired pneumonia?
- Strep pneumoniae (typical)
- Mycoplasma pneumoniae (walking - atypical), virus (atypical)
hospital acquired pneumonia?
- Staph (bc they get it from the staff!) MRSA
- SPACE
Lymphoid interstitial pneumonia:
- usually associated with?
- radiology?
- Histo?
- treat?
usually associated with autoimmune diseases or immunodeficiency. Can transform to pneumonia.
- centrilobular nodules
- germinal centers
- immunosuppression
Eosinophilic pneumonia:
- presentation
- treatment?
- Acute eosinophilic pneumonia
- mimics ARDS (sim. to acute interstitial pneumonia) - Chronic eosinophilic pneumonia
- more in nonsmokers and women
lots of eosinophilic infiltrates
steroid responsive
Lymphangioleiomyomatosis
- what is it?
- what complications are common?
- treatment?
cystic lung disease only in young women
pleural effusions, spontaneous pneumothorax
anti-estrogen therapy
Hypersensitivity pneumonitis
- what is it?
- symptoms
- radiology?
- Histo?
immunologic response to inhaled antigen
(Acute and Chronic - just like eosinophilic P)
cough. DOE
upper lobe predominant
inflammation with poorly formed granulomas
Sarcoidosis:
- which organs most affected?
- presentation?
- do they have restrictive or obstructive pattern?
- histo?
- treatment?
- Lungs, eyes, Skin
- Lymphadenopathy, chest pain, cough, wheezing,
- may be mixed pattern
- non-caseating granuloma
- treatment often not necessary
What bacteria is most common in:
community acquired pneumonia?
hospital acquired pneumonia?
community acquired pneumonia?
- Strep pneumoniae
hospital acquired pneumonia?
- Staph (bc they get it from the staff!) MRSA
- SPACE
If pt has sepsis, what should you be suspicious of? Describe its treatment.
> 50% of causes of ARDS result from sepsis
If ventilating the patient, make sure TIDAL VOL IS LOW - lungs are healing bro,
