Flashcards: Diffuse Interstitial Lung Disease Fundamentals — 16 cards

Diffuse infiltrative pneumopathies — definition?

Heterogeneous group with diffuse interstitial infiltration.

Pulmonary interstitium — function?

Supports airways, septa, and pleura tissues.

Interstitial infiltration pattern — types?

Cellular or fibrous, fibrosis is irreversible.

Diffuse interstitial opacities — radiologic feature?

Shared presentation across pneumopathies.

Pathogenesis — overshoot mechanism?

Persistent injury leads to fibrosis.

Acute PID — duration?

Less than 3 weeks.

Subacute/chronic PID — classification?

Known cause or unknown cause.

Major acute PID etiologies?

Infections, hemodynamic causes, ARDS, exacerbation.

Workup for PID — key step?

Multidisciplinary approach with imaging and tests.

HRCT — role?

Analyzes elementary imaging signs.

Major chronic PID causes — groups?

Connective tissue, granulomatous, exposure, drugs, others.

Treatment principle — cause?

Treat the identified cause.

Idiopathic pulmonary fibrosis — treatment?

Antifibrotic drugs; no steroids.

Sarcoidosis — management?

Surveillance or anti-inflammatory therapy.

Lofgren syndrome — treatment?

Anti-inflammatory approach.

IPF prognosis?

Median survival 2.5–3.5 years.
