1. Interstitial lung disease(ILD), or diffuse parenchymal lung disease (DPLD), is a group of lung diseases affecting the interstitium (the tissue and space around the alveoli (air sacs of the lungs).
  2. It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic
  3. It may occur when an injury to the lungs triggers an abnormal healing response. Ordinarily, the body generates just the right amount of tissue to repair damage, but in interstitial lung disease, the repair process goes awry and the tissue around the air sacs (alveoli) becomes scarred and thickened.
  4. This makes it more difficult for oxygen to pass into the bloodstream. The term ILD is used to distinguish these diseases from obstructive airways diseases.
  5. Prolonged ILD may result in pulmonary fibrosis, but this is not always the case.
  6. Idiopathic pulmonary fibrosis is interstitial lung disease for which no obvious cause can be identified (idiopathic) and is associated with typical findings both radiographic (basal and pleural-based fibrosis with honeycombing) and pathologic (temporally and spatially heterogeneous fibrosis, histopathologic honeycombing, and fibroblastic foci).

Frequently Asked Questions

Ans: Not exactly the treatment for ILD depends upon the type of ILD. If ILD is due to silica dust or asbestos exposure the treatment is different, If it is IPF then drugs are available for reducing progression.

Ans: Lung transplantation is the only cure for ILD.
