Idiopathic interstitial pneumonia (IIP), or noninfectious pneumonia [1] are a class of diffuse lung diseases. These diseases typically affect the pulmonary interstitium, although some also have a component affecting the airways (for instance, cryptogenic organizing pneumonitis). There are seven recognized distinct subtypes of IIP. [2]
It is a type of chronic pulmonary fibrosis characterized by a progressive and irreversible decline in lung function. [6] [3] [4] The tissue in the lungs becomes thick and stiff, which affects the tissue that surrounds the air sacs in the lungs. [7] Symptoms typically include gradual onset of shortness of breath and a dry cough. [1]
The average rate of survival for someone with this disease is between three and five years. [5] The term ILD is used to distinguish these diseases from obstructive airways diseases. There are specific types in children, known as children's interstitial lung diseases. The acronym ChILD is sometimes used for this group of diseases. [6]
Usual interstitial pneumonia (UIP) is a form of lung disease characterized by progressive scarring of both lungs. [1] The scarring (pulmonary fibrosis) involves the pulmonary interstitium (the supporting framework of the lung). UIP is thus classified as a form of interstitial lung disease.
Sixty percent of people with acute interstitial pneumonitis will die in the first six months of illness. [3] The median survival is 1 + 1 ⁄ 2 months. However, most people who have one episode do not have a second. People who survive often recover lung function completely. [citation needed]
The fibrosing pattern of NSIP has a five-year survival rate of 86% to 92%, while the cellular pattern of NSIP has a 100% five-year survival rate. Patients with NSIP (whether cellular or fibrosing), have a better prognosis than those with usual interstitial pneumonia (UIP).
Pulmonary function testing in people with organizing pneumonia, either cryptogenic or due to secondary causes, shows a restrictive defect with a decrease in the gas absorptive capacity of the lungs (seen as a decrease in the diffusion capacity of carbon monoxide). [9] Airflow obstruction is usually not seen on pulmonary function testing. [9]
Causes include environmental pollution, certain medications, connective tissue diseases, infections, and interstitial lung diseases. [1] [3] [6] But in most cases the cause is unknown (idiopathic pulmonary fibrosis). [1] [3] Diagnosis may be based on symptoms, medical imaging, lung biopsy, and lung function tests. [1]
