What is non-specific interstitial pneumonia?

Non-specific interstitial pneumonia (NSIP) patients are usually younger that people with IPF, and more likely to be female.

Causes of non-specific interstitial  pneumonia

Non-specific interstitial pneumonia can be associated with  autoimmune diseases such as systemic sclerosis, systemic lupus erythematosus (SLE), Sjogren’s syndrome and rheumatoid arthritis.

It can also be idiopathic, which means no specific cause can be  identified.


People with NSIP are usually breathless and may have a cough. They may also experience other symptoms of autoimmune diseases such as skin rashes, joint pains, dry eyes, dry mouth, mouth ulcers and fatigue.  Find out more about pulmonary fibrosis and its symptoms.


Typically, you will be offered a trial of immunosuppressive therapy, particularly if the NSIP is associated with an autoimmune disease.

You may also be offered pulmonary rehabilitation and oxygen therapy to help improve your quality of life.

Ongoing treatment

Your medical team will monitor your lung disease  regularly to determine if your treatment is effective.


In general, the life expectancy  for NSIP is better than for people with idiopathic pulmonary fibrosis. Patients usually survive for five  years after diagnosis, with 26-40% living for more than ten years. However, life expectancy is determined by  rate of disease progression and response to treatment.
