The key differential is a usual interstitial pneumonitis (UIP) pattern, with which there can be some overlap in imaging features 3. Imaging features can overlap between cellular and fibrotic types as well as usual interstitial pneumonitis (UIP) in as high as 30% of patients. Bronchoalveolar lavage (BAL) has been crucial in elucidating the immune effector cells involved in the inflammatory processes in idiopathic interstitial pneumonias 1. Kim DS, Collard HR, King TE. Idiopathic pulmonary fibrosis (IPF), the most common and lethal of the idiopathic interstitial pneumonias, is defined by a radiological and/or pathological pattern of usual interstitial pneumonia (UIP). Check for errors and try again. Semin Respir Crit Care Med. NSIP has a relative good prognosis and the majority of patients respond to treatment with corticosteroids. Involvement tends to be subpleural and generally symmetrical with an apicobasilar gradient. 7. Also, temporal changes in the pattern of HRCT findings in subsequent studies shown in as high as 28% of cases resulted in the change of provisional diagnosis from NSIP to UIP.

Current status of idiopathic nonspecific interstitial pneumonia. Nonspecific interstitial pneumonia associated with polymyositis and dermatomyositis: serial high-resolution CT findings and functional correlation. Radiologically, the main feature required for a confident diagnosis of UIP is honeycomb change in the periphery and the lower portions (bases) of the lungs. NSIP is temporally and spatially homogeneous, while UIP is typically heterogeneous, patchy, and irregular in size. Classification and natural history of the idiopathic interstitial pneumonias. Cellular NSIP shows an even better response to corticosteroids and carries a substantially better prognosis than the fibrotic type. NSIP; Diagnostic Criteria. 27 (3): 595-615. Radiographics.

Overview of Interstitial Lung Disease (ILD) Interstitial lung disease is a broad term for a number of diseases that lead to inflammation or scarring of the lungs, leading to fibrosis. The presence of the following features, although they can be seen in NSIP, should make us think about other differentials: In general, non-specific interstitial pneumonia (NSIP) carries a much more favorable prognosis than a UIP-type pattern with 90% 5-year survival rate for cellular and ~60% (range 45-90%) 5-year survival in the fibrotic subtype. Case Discussion. 6. Mycophenolate mofetil (MMF) has also shown to improve lung function 15.

Primarily idiopathic but the morphological pattern can be seen in association with a number of conditions: If there is no underlying cause, it is termed idiopathic NSIP; which is now considered a distinct entity. 1987;149 (2): 265-8. Moreover, a histologic diagnosis of NSIP often does not constitute a final diagnosis, since it might reflect hypersensitivity pneumonitis, collagen vascular disease, or drug-induced lung disease; and in fact collagen vascular disease and drug reactions can look like UIP, cryptogenic organizing pneumonia (COP), and various … It can be normal in early stage of disease and in plain radiographs. However more recently the term idiopathic pulmonary fibrosis has been applied solely to the clinical syndrome associated with the morphologic pattern of UIP, with the specific exclusion of entities such as non-specific interstitial pneumonia (NSIP) and desquamative interstitial pneumonia (DIP) 1. Hartman TE, Swensen SJ, Hansell DM et-al.

Biopsy-proved idiopathic pulmonary fibrosis: spectrum of nondiagnostic thin-section CT diagnoses. Historically non-specific interstitial pneumonia was divided into three groups; however, due to similar outcomes, groups II and III (mixed cellular and fibrotic and mostly fibrotic, respectively) are now both classified as fibrotic type: Important negative histological findings are the absence of acute lung injury including hyaline membranes, granulomas, organisms or viral inclusions, dominant airways disease or organizing pneumonia, eosinophils and coarse fibrosis. The presence of macroscopic honeycombing is almost diagnostic for UIP. 2012;33 (05): 440-9. Poletti V, Romagnoli M, Piciucchi S et-al. 11. Simmons JT, Suffredini AF, Lack EE et-al. NSIP ranges from type I which is a cellular pattern seen as ground glass opacity on HRCT to type IV with a fibrotic pattern, which may be … Arakawa H, Yamada H, Kurihara Y et-al. 17. 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. The term is used for cases of interstitial pneumonia in which diagnostic features of UIP, DIP, AIP, or COP are not present. Thorax … Differentiating Chronic HP, NSIP, & UIP – Radiology Rounds 2. High-resolution computed tomography features of nonspecific interstitial pneumonia and usual interstitial pneumonia. Idiopathic pulmonary fibrosis (IPF), which has the histological pattern of usual interstitial pneumonia (UIP), is a progressive interstitial lung disease with a poor prognosis. Nonspecific interstitial pneumonia: evolving concepts. Kim TS, Lee KS, Chung MP et-al. The features which favor the diagnosis of NSIP over UIP are symmetrical bilateral ground-glass opacities with fine reticulations and sparing of the immediate subpleural space. 2010;254 (3): 957-64. The Journal of rheumatology. Solely or predominantly upper lobe involvement or purely unilateral disease makes the diagnosis of NSIP less likely. Nonspecific Interstitial Pneumonia NSIP is less common than UIP but is still one of the most common histologic findings in patients with IIPs (, 21). Nonspecific interstitial pneumonia and idiopathic pulmonary fibrosis: changes in pattern and distribution of disease over time. NSIP accounts for 14–35% of biopsies performed for chronic interstitial pneumonia. NSIP may be idiopathic or associated with collagen vascular diseases or exposure to drugs or chemicals. UIP may be diagnosed by a radiologist using computed tomography (CT) scan of the chest, or by a pathologist using tissue obtained by a lung biopsy. NSIP is temporally and spatially homogeneous, while UIP is typically heterogeneous, patchy, and irregular in size.36 The extent of honeycombing and traction bronchiectasis is greater in UIP than the extent of ground glass opacity or micronodules, which are more commonly associated with an NSIP pattern.536, Copyright © 2019, Boehringer Ingelheim Pharmaceuticals, Inc.

Cox regression analysis examined the relationships between histopathological and radiological diagnoses and mortality, controlling for Pulmonary drug toxicity: radiologic and pathologic manifestations. Correct and early diagnosis has a significant impact on patients' outcome because NSIP usually responds well to the corticosteroid therapy or cessation of inciting causes like drugs or organic allergens 12. The NSIP pattern is the second most common pattern, and always part of the differential diagnosis of the usual interstitial pneumonia (UIP) pattern, but NSIP has a better prognosis than UIP Multidisciplinary discussion is necessary to make the diagnosis and decide treatment direction Radiographics. 2005;29 (3): 339-45. Non-specific interstitial pneumonia (NSIP) is the second most common morphological and pathological pattern of interstitial lung diseases. In a heterogeneous group of subjects with CTD, no significant difference in survival was noted between patients with CTD-related NSIP and UIP . Among all the ILD patterns, usual interstitial pneumonia (UIP) and nonspecific interstitial pneumonia (NSIP) are the most frequent, accounting for 40-60% and 11-30% of cases, respectively [28].

Immediate subpleural sparing, when present is considered very specific for NSIP. Organizing pneumonia is caused by inflammation 10 and may be idiopathic in nature, termed cryptogenic organizing pneumonia, or may occur secondary to infection, collagen vascular disease, or drug toxicity. Clinical, Epidemiological, and Histopathological Features of Respiratory Involvement in Rheumatoid Arthritis Smoking is not associated, and it is not a protective factor either. Overall prevalence is higher in women due to high association with collagen vascular diseases, but the prevalence of idiopathic NSIP is similar in both genders.
