Feb 5, 2025 · In general, non-specific interstitial pneumonia (NSIP) carries a much more favorable prognosis than a usual interstitial pneumonia (UIP) pattern, with a 90% 5-year survival rate for the cellular subtype and a ~60% (range 45-90%) 5-year survival for the fibrotic subtype.

Several key features can help to distinguish NSIP from UIP. While helpful, the differences between UIP and NSIP are often not as obvious as this figure suggests, and the difficulty lies in distinguishing the cases that lie toward the middle.

Oct 14, 2024 · Usual interstitial pneumonia (UIP) is not a disease, it is a histopathologic and radiologic pattern of interstitial lung disease. This can be caused by idiopathic pulmonary fibrosis, fibrotic hypersensitivity pneumonitis or non-specific interstitial pneumonia. The diagnosis is typically decided by a multidisciplinary team.

Nonspecific interstitial pneumonia (NSIP) can be idiopathic or can be seen in association with connective tissue disease, HIV infection, a variety of drugs, and hypersensitivity pneumonitis.

Sep 28, 2023 · What is nonspecific interstitial pneumonia (NSIP)? Nonspecific interstitial pneumonia (NSIP) is inflammation in the spaces between the air sacs in your lungs (alveoli) and the blood vessels around them. It’s a type of interstitial lung disease.

Aug 14, 2023 · Nonspecific interstitial pneumonia (NSIP) is one class of idiopathic interstitial pneumonia (IIP). NSIP is chronic interstitial pneumonia with the homogeneous appearance of interstitial fibrosis and inflammation.

Nov 16, 2023 · NSIP may be divided into two forms: cellular NSIP and fibrotic NSIP. Cellular NSIP (~20%) has a greater component of acute inflammation. It may be more responsive to steroid or immunosuppression, with a greater degree of reversibility.

Sumikawa et al. have reported that about 90 % of pathological NSIP showed NSIP pattern at HRCT, while 28 % of pathological UIP showed NSIP pattern at HRCT. They also reported that less reticulation and more GGO on HRCT play an important role …

4 days ago · This table shows several HRCT features commonly seen in patients with chronic hypersensitivity pneumonitis, UIP or IPF, and NSIP. Note the significant overlap of certain features such as reticulation and ground glass opacity, and those which are not common for …

Sep 12, 2018 · PPFE, the newest pathologic subcategory, is rare and highlighted by pleural thickening predominantly in the upper lobes. It is often associated with parenchymal or interstitial findings on CT, most commonly UIP and NSIP.
