Idiopathic nonspecific interstitial pneumonia: Waters remain murky...remember ABCDEFGHI.

This article from the medical journal Lung India explores the uncertainties and controversies surrounding idiopathic nonspecific interstitial pneumonia (NSIP). NSIP is a condition characterized by inflammation and fibrosis in the alveolar septae. The article discusses the various underlying conditions and associations of NSIP, as well as the challenges in diagnosing the condition. It also mentions a study that found 64% of NSIP cases to be idiopathic, while 36% were secondary to known causes. However, the study had limitations, and the article calls for future research to provide more comprehensive information. [Extracted from the article]
