Is interstitial lung disease an allergic or immune problem?

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).
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.

What makes pneumonia not an interstitial lung disease?

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). Read more...

What is the progression of interstitial lung disease?

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. Read more...
