ILD progression. Interstitial lung disease refers to a group of disorders that affect the area of the lung that supports the alveoli. In order to give a prognosis for interstitial lung disease, you must know the specific disease causing it. This usually requires a lung biopsy. Some causes of interstitial lung disease are treatable - others are not.
Depends on the kind. Progression depends on the kind of interstitial lung disease (ild). There are more than 200 different kinds.
Treat cause. Interstitial lung disease (ild) has many possible causes and some do not progress. For example inhaled substances, drugs, arthritis, and infectious causes can often be treated if the offending agent is identified, exposure is stopped and appropriate treatment started. Autoimmune disease causes can be treated. Idiopathic pulmonary fibrosis, cancer, or unknown causes may progress more rapidly.
Depends on type. There are several types of interstitial lung disease and the prognosis and rate of progression of lung disease depend on the type of disorder causing it. Most of them are chronic slow to progress and may take years before significant impairment of functional status occurs. Talk to a lung specialist to get more information about your case and its prognosis.
See below. By history and physical, including your symptoms, occupational and other exposures etc; x-rays and ct scans and pulmonary function tests. You may also need a biopsy.
No. Bacterial pneumonia is not generally considered interstitial lung disease. However, some forms of interstitial lung disease are referred to as iip or idiopathic interstitial pneumonia. These diseases are not pneumonia in the classic sense. They are not thought to be infectious in etiology.
Pneumonia. Interstitial lung diseases are typically progressive processes that are not commonly associated with infection. They may ultimately be associated with fibrosis. That being said there are pneumonias that present with an, "interstitial pattern, " on chest x-ray. They are known as interstitial pneumonias. Interstitial pneumonia will not progress to diffuse fibrosis and are not considered ilds.
No. Pneumonia generally refers to infection of the lungs due to a bacteria, fungal or viral organisms. Ild is an ill understood disease, generally caused by inflammation.
They are different. A pneumonia is caused by an organism causing destruction of the lung tissue. Interstitial lung disease is inflammation of the lung and usually starts in the "interstitium" but later can involve other parts of the lung. But, one is felt to be an infection, while the other is more"immune" caused. The picture is of a pneumonia in the left of the picture (all the white area compared to the dark).
Both and others. Interstital lung disease refers to the supporting structures, tissues and cells supporting the alveoli of the lung. When this is inflammed or scarred the thickening reduces oxygen-co2 exchange. There are many possible causes for ild and the two you listed are possible causes.
Usually immune. There are some interstitial lung diseases caused by allergies to mold and bird droppings, but most are caused by an abnormal immune response in the lung. There is an abnormal repair process that leads to fibrosis (scar tissue) which replaces normal lung tissue. Hypersensitivity pneumonitis is an interstitial disease caused by an exaggerated immune reaction to foreign protein that is inhaled.
Depends on the type. Interstitial lung disease is a generalized term used to describe multiple diseases that affect the interstitial tissue (the lung tissue among the airways). Some of them can be related to immune problem esp., if the patient has autoimmune disease such as rheumatoid arthritis, or lupus etc. Some of them related to allergy and the others are idiopathic (we do not know what causing the disease).
Interstitium. Is that area between the walls of the air sacs or alveoli. Oxygen diffuses from the air sacs to the blood vessels located in the interstitial area. Ild is the presence of inflammation in that area making the distance for diffusion of the oxygen farther for the traveling or flowing blood to pick up. If the inflammation causes scarring it is pulmonary fibrosis.
