Notes:

Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD),[1] is a group of lung diseases affecting the interstitium (the tissue and space around the air sacs of the lungs).[2] It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, perivascular and perilymphatic tissues. 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. This makes it more difficult for oxygen to pass into the bloodstream. The term ILD is used to distinguish these diseases from obstructive airways disease

ILD may be classified according to the cause.[5] One method of classification is as follows:

   Inhaled substances
       Inorganic
           Silicosis
           Asbestosis
           Berylliosis
       Organic
           Hypersensitivity pneumonitis
   Drug-induced
       Antibiotics
       Chemotherapeutic drugs
       Antiarrhythmic agents
       Statins
   Connective tissue and Autoimmune diseases
       Systemic sclerosis
       Polymyositis
       Dermatomyositis
       Systemic lupus erythematosus
       Rheumatoid arthritis
   Infection
       Atypical pneumonia
       Pneumocystis pneumonia (PCP)
       Tuberculosis
       Chlamydia trachomatis
       Respiratory Syncytial Virus
   Idiopathic
       Sarcoidosis
       Idiopathic pulmonary fibrosis
       Hamman-Rich syndrome
       Antisynthetase syndrome
   Malignancy
       Lymphangitic carcinomatosis
