Cellular NSIP

Cellular non-specific interstitial pneumonitis. Dr Yuranga Weerakkody and Dr Amir Rezaee et al. Cellular non-specific interstitial pneumonia is one of the two histological subtypes of non-specific interstitial pneumonia (NSIP). It is less common compared with fibrotic NSIP but carries a much better prognosis. On this page Some patients also have idiopathic NSIP, which means that the specific cause of the lung disease is unknown. What are the forms of nonspecific interstitial pneumonia (NSIP)? There are two primary forms of NSIP — cellular and fibrotic. The cellular form is defined mainly by inflammation of the cells of the interstitium Cellular type Changes are predominantly cellular, with scant fibrosis; Better prognosis; Fibrotic type Changes are predominantly fibrotic, with less cellularity; NSIP is a diagnosis of exclusion; The following features should not be seen Granulomas or giant cells; Bronchiolocentric distributio Non-specific interstitial pneumonia (NSIP) is the second most common morphological and pathological pattern of interstitial lung diseases.NSIP has two main subtypes: fibrotic type: most common, having a more dismal outcome; cellular type: less common, but carries a much better prognosis due to a very good response to treatment; On imaging, the most common features are relatively symmetric and.

Cellular NSIP is often inflammation of the cells in the interstitium (fluid-filled space between alveolar membranes and the interstitial capillaries). Fibrotic NSIP is when the lung tissue begins to scar and thicken. The scarring (fibrosis) is irreversible and can cause lungs to work less efficiently, reducing the levels of oxygen in the blood.. Cellular NSIP is much less common than fibrotic NSIP (, 14 31). It is often characterized by the absence of severe fibrotic changes or honeycombing. Sumikawa et al (, 8) and Tsubamoto et al (, 9) evaluated the extent of parenchymal abnormalities in both cellular and fibrotic NSIP. Although there was a greater degree of reticulation in. Both types of NSIP can be present at the same time, but patients with the cellular type usually have a better prognosis. 1. Symptoms of Nonspecific Interstitial Pneumonia. Symptoms of NSIP include: Dry cough. Shortness of breath/labored breathing that worsens with activity and overtime. Fatigue (tiredness) Cellular or fibrotic change Lymphocytic or plasmacytic infiltration Loose fibrosis Lung architecture is frequently preserved Cellular NSIP or fibrotic NSIP can be stated specifically in pathologist report Features of interstitial pneumonia with autoimmune features (IPAF) (Chest 2010;138:251): Lymphoid aggregates with germinal cente

I was recently diagnosed with cellular NSIP. I was an active healthy 50 year old last October when I started getting short of breath and a constant cough. I thought it was pnemonia and so did the doctor. After 4 round of antibiotics I wasn't better so they started looking at other options. I had further tests and eventually a VATS lung biopsy 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. When idiopathic, NSIP is considered one of the idiopathic interstitial pneumonias (IIPs), which also include usual interstitial pneumonia (UIP)/idiopathic. Idiopathic non-specific interstitial pneumonia (NSIP) is a rare clinical disorder and it can be classified into cellular NSIP (c-NSIP) or fibrotic NSIP patterns. Both clinical conditions manifest with ground glass opacities (GGO), irregular linear opacities, and consolidations in a bilateral, symmetrical or subpleural distribution Nonspecific interstitial pneumonia (NSIP) is an idiopathic interstitial pneumonia.It is much less common than idiopathic pulmonary fibrosis (IPF). Most patients are women, are between the ages of 40 and 50, and have no known cause or association I would like to message anyone who has had cellular NSIP for longer than 6 months. 3 months ago I was diagnosed with Cellular NSIP and told I should go in remission in 3 to 6 months. I would like to know how long it took them to come off O2 without sats dropping and go into remission themselves

Cellular non-specific interstitial pneumonitis Radiology

of the spectrum, idiopathic cellular NSIP and DIP have a survival rate of nearly 100% (14,15). How-ever, the survival rate of idiopathic fibrotic NSIP is far worse than that of cellular NSIP but better than that of UIP: 5-year survival rates range from 45% to 90% and 10-year survival rates are only 35% (Fig 1) (14,16-18). Pathologic Feature The cellular form of NSIP supposedly responds better to steroids and other immunosuppressants, but usually they can tell on HRCT if you have ground glass or other inflammatory changes that that would benefit from those medicines. Many people have both fibrotic and cellular. I have resisted a biopsy for years, though my doctor encouraged it (it. In NSIP patients with a progressive course a trial of treatment with steroids combined with azathioprine or cyclophosphamide should be undertaken in a similar way to the recommendations for IPF. NSIP patients with lymphocytic alveolitis and a predominant ground glass appearance (cellular NSIP) generally respond well to this type of treatment The pathological diagnosis of cellular nonspecific interstitial pneumonia (NSIP) was made after video assisted thoracic surgery. She did not have muscle weakness or arthralgia but she had a skin lesion (mechanic's hand) which is often seen in patients with antisynthetase syndrome. Anti-Jo-1 antibody was negative but anti-OJ antibody was positive The fibrosing pattern of NSIP has a five-year survival rate of 86% to 92%, while the cellular pattern of NSIP has a 100% five year survival rate. Patients with NSIP (whether cellular or fibrosing), have a better prognosis than those with usual interstitial pneumonia (UIP). Reference

No. NSIP comes in two distinct types—cellular and fibrotic. Cellular NSIP generally responds well to treatment. Fibrotic NSIP is more difficult to treat. Is there a role for IPF medications (OFEV and Esbriet) in the treatment of NSIP? At the present time we have no data suggesting any benefit to using IPF treatments in NSIP Both cellular NSIP and classic HP enter the differential diagnosis of LIP as well, and their contrasting features are summarized in Table 2.3. The most important features in the differential diagnosis include the greater density of the infiltrate in LIP and the resultant marked alveolar septal widening and distortion without fibrosis

Histologically, NSIP is divided into cellular and fibrosing patterns. The rarer cellular NSIP pattern is characterized by mild-to-moderate interstitial chronic inflammation with a mixture of lymphocytes and plasma cells (Fig. 16.4, E-Slide 16.2). Lymphoid aggregates are a common finding Prognosis for both types of NSIP is usually very positive. The cellular type typically has higher survival rates. However, even NSIP has a five-year survival rate of only 86 to 92 percent. Cryptogenic organizing pneumonia (COP) COP is a disease of the bronchioles and the alveoli in the lungs Shown are cellular interstitial infiltrates without fibrosis in a patient with cellular NSIP (hematoxylin-eosin, original × 150). Top right, B: Intermediate prognosis: linear fibrosis. There is homogeneous interstitial fibrosis that follows the original alveolar walls and no architectural distortion. This is a case of fibrotic NSIP. Background: In severe, progressive interstitial lung disease (ILD), specific diagnosis is often difficult, and treatment therefore empirical. An effective, rapidly acting, well-tolerated therapy is desirable. This study reviews the tolerability and efficacy of i.v. cyclophosphamide in known or suspected non-specific interstitial pneumonia (NSIP) following the introduction of an i.v. NSIP or UIP, respectively, and there do in fact exist published data to support the worse prognosis of fibrotic compared to cellular NSIP pattern in pa-tients with collagen vascular disease.8 In terms of high-resolution CT (HRCT) findings, similar separations can be made: chronic interstitial diseases characterized by airspace opacificatio

The CD20+ lymphocyte infiltration in the lymphoid follicles of the patients with cellular NSIP [121.33 (63.54-282.88)/.1 mm 2] was less dense than in patients with fibrosing NSIP [255.08 (132. The NSIP, cellular pattern consisted primarily of mild to moderate interstitial chronic inflammation, usually with lymphocytes and a few plasma cells (Figs. 5 and 6). Typically, the lung was involved uniformly, but the distribution of the lesions was often patchy. The.

The chronic inflammatory interstitial infiltrates of cellular NSIP may closely resemble the chronic interstitial pneumonia that is seen in other diagnoses. While cellular interstitial pneumonia is a component of hypersensitivity pneumonia, NSIP typically lacks the accompanying chronic bronchiolitis, scattered poorly formed granulomas, and OP.. Cellular NSIP is often characterized by the absence of severe fibrotic changes or HC. The most common CT findings of NSIP are GGO (Fig. 21.1) and fine reticular abnormality . Traction bronchiectasis may be present or absent. All these findings have a symmetric lower lung zone distribution

2 types (a) cellular NSIP (b) Fibrotic NSIP (more common) Fibrosis may involve alveolar septa, peribronchivascular interstitium, interlobular septa and visceral pleura. Prognosis of fibrotic NSIP is worse , cellular NSIP has good prognosis. HRCT finding may show both, airspace and interstitial patterns. 4 Cellular NSIP is often inflammation of the cells in the interstitium (fluid-filled space between alveolar membranes and the interstitial capillaries). Fibrotic NSIP is when the lung tissue begins to scar and thicken ; with the cellular form of NSIP, particularly in cases associated with a collagen vascular disease or immunodeficiency. However.

Nonspecific Interstitial Pneumonia (NSIP): What is it

Nonspecific Interstitial Pneumonia - Surgical Pathology

Non-specific interstitial pneumonia Radiology Reference

Fibrotic NSIP may respond to steroids, although generally fibrotic NSIP has a much worse prognosis than cellular NSIP, and therefore is more similar to UIP in prognosis and response to steroids. NSIP is a common histologic pattern in collagen vascular diseases involving the lung (see Chapters 86 and 113 ) Thirty-one patients (15 males and 16 females) were pathologically identified as NSIP and subclassified into either the cellular (n=16) or fibrotic group (n=15). All 31 patients were clinically considered to be idiopathic NSIP cases. Patients with idiopathic BOOP (n=16) and IPF (n=64) were compared with the NSIP patients

What You Should Know About Nonspecific Interstitial

  1. Cellular-NSIP and OP showed better prognoses than fibrotic-NSIP, UIP or DAD. In addition, CVDs had better prognoses than IIPs, when compared on the basis of the same histopathological patterns. Furthermore, the prognoses in the CsA-treated group were significantly better than in those without CsA treatment in regard to acute exacerbation of UIP.
  2. NSIP is histologically characterized by a homogeneous, uniform pattern of cellular interstitial inflammation associated with variable degrees of fibrosis. In contrast, UIP is associated with extensive fibrosis which is temporally inhomogeneous (i.e. various lesions are of different ages). NSIP is a very inhomogeneous group
  3. imal fibrosis or scarring as opposed to Fibrotic NSIP which is mainly fibrotic or scarring and
  4. Nonspecific interstitial pneumonia (NSIP) has variable clinical, patho-logic, and radiologic manifestations. Cellular and fibrotic NSIP are the two main histologic subtypes and differ from one another in the de-gree of inflammation and fibrosis. It is important to differentiate NSIP
  5. imal fibrosis on lung biopsy and a better response to immunosuppression. BAL will show a non‐specific lymphocytosis (50%) with an increase in the number of neutrophils and eosinophils
  6. Since 1994 there have been seven additional reports of NSIP, including that of Travis et al., 1-3,6,8-10 and the concept of NSIP has evolved from a broad, inclusive term into a specific form of idiopathic interstitial pneumonia. Histologically it is a uniform-appearing, cellular interstitial pneumonia characterized by a lymphoplasmacytic.
  7. TRX1 was weakly expressed in the lungs of cellular NSIP and COP. TRX1 producing cells in UIP (n=16), fibrotic NSIP (n=15), cellular NSIP (n=4), and COP (n=5) were significantly increased when compared to nonsmokers (n=7). TRX1 producing cells in UIP and fibrotic NSIP were significantly increased when compared to cellular NSIP and COP

loss of alveolar structure, while the key feature of NSIP in comparison with UIP is an absence of temporal heteroge-neity of the fibrous tissue. The 31 patients with NSIP were subdivided into two groups (cellular and fibrotic groups), which were further subcategorized according to the classification system of Table 1 Because the prognosis of cellular NSIP has been reported to be clearly different (much better) from that of IPF-UIP or fibrotic NSIP (9, 10, 12), only patients with fibrotic NSIP were included. Individual CVDs were diagnosed according to the criteriaof corresponding societies (see References 23-30 and Table 1). Metho Idiopathic NSIP could be separated into cellular and fibrotic patterns because these histological patterns are associated with different clinical characteristics and prognosis. 11, 13, 14 Patients with idiopathic cellular NSIP had a more favourable outcome than those with idiopathic fibrotic NSIP and IPF. 11, 13, 14 In the current study. NSIP is a type of interstitial lung disease characterized by ground glass opacities and some scarring on CT scan. On lung biopsy there is a more uniform distribution of inflammation within the lung and generally less scarring than IPF. There are two broad types of NSIP, cellular and fibrotic

There is no fibroblastic proliferation. The appearance of the abnormality is uniform throughout the specimen and thus the term 'temporal uniformity is applicable. Sourc Narrowing the Differential Diagnosis. A correct diagnosis is crucial to ensure successful management of a patient with ILD. 27 Furthermore, an accurate diagnosis allows the physician to provide his or her patient with appropriate prognostic information, and develop a suitable management strategy with the patient and caregiver. 29 This figure shows the average survival for patients with UIP or. These include fibroblastic foci (21%), foci of OP (52%), lymphoid follicles (57%) and spotty intra-alveolar macrophages. 7, 56 Marked architectural distortion is not present. 56, 57 A sample biopsy from a patient with cellular NSIP can be seen in Figure 1 along with a HRCT from the same patient

What is Nonspecific Interstitial Pneumonia (NSIP)? Inoge

In contrast, previous NSIP was incompatible because of its primary pathologic diagnosis of cellular NSIP (n = 3) or associated pathologic findings of acute inflammatory changes (n = 21), such as prominent organizing pneumonia, alveolar epithelial injury and interstitial cellular infiltration, surrounded by collapse with few hyaline membranes NSIP can be categorized by cellular type or fibrotic type, according to the grade of inflammation and fibrosis. The cellular type has mostly inflammatory lesions with good responses to steroid, but the fibrotic type has a large proportion of fibrosis mixed with inflammatory lesions and a relatively poor response to steroid treatment.[1

HRCT images of patient #9 (76-years-old female, pathologically cellular NSIP). a The coronal image of the high-resolution computed tomography (HRCT) showed bilateral volume loss and infiltration. Patients with nonspecific interstitial pneumonia (NSIP) in all lobes were categorized as having fibrotic (n = 25) or cellular NSIP (n = 5). No consistent distribution of lobar histology was noted. Patients concordant for UIP were older (63 +/- 9 [mean +/- SD] yr; p < 0.05 as compared with all other groups) than those discordant for UIP (57. Patients with idiopathic NSIP, cellular pattern had a better 5- and 10-year survival than those with idiopathic NSIP, fibrosing pattern (100% vs 90% and 100% vs 35% respectively, p = 0.027). Survival of patients with idiopathic UIP was worse than that of patients with idiopathic NSIP, fibrosing pattern (p = 0.014)

  2. From 1996 to 2008, a total of 438 patients who were suspected of having an ILD underwent surgical lung biopsy at Samsung Medical Center, a tertiary referral center in Seoul, Korea. Patients who had received histologic diagnoses of cellular NSIP or other ILD were excluded; patients with a history of collagen vascular disease were also excluded
  3. Thomas et al. (2002) noted that cellular NSIP may be a precursor of UIP and ultimately fibrosis in this family. The presence of different pathologic findings in affected relatives sharing the same mutations suggested pleiotropic manifestations of the same central pathogenesis. Tredano et al. (2004) and Brasch et al. (2004) reported a child with.
  4. Cellular NSIP mainly consists of inflammatory cell infiltration [2, 25]. The typical pathological features of fibrotic NSIP (fNSIP) are characterized by homogeneous and diffuse fibrosis with interstitial deposition of collagen and chronic inflammatory cells [24, 27]. The fNSIP had a larger architectural distortion . 81
  5. What is NSIP? NSIP is a fairly uncommon disease that affects the tiny air sacs, called alveoli, found within the lungs. The walls of the alveoli become swollen, as does the thin covering that protects the lungs, called the pleura. Two forms of NSIP exist, known as cellular and fibrotic

The radiologic pattern may overlap that of UIP, but ground-glass attenuation is usually more common in NSIP and is the salient feature of cellular NSIP,11,13 and hon-eycombing is rare at diagnosis.7,12 Lower lobe. Many people living with interstitial lung disease often wonder about their interstitial lung disease life expectancy. Interstitial lung disease (ILD) is a category of chronic lung conditions that affect the interstitium. More than 200 types of interstitial lung diseases exist, such as pulmonary fibrosis.Many factors go into interstitial lung disease life expectancy Patients with NSIP (whether cellular or fibrosing), have a better prognosis than those with usual interstitial pneumonia (UIP) Non-specific interstitial pneumonia (NSIP) was the most common HRCT pattern (52%), followed by NSIP overlapping with organizing pneumonia (OP) (22%). Thirty-nine subjects had biopsy data In 1994, Katzenstein and Fiorelli reported the histological features and clinical significance of non-specific interstitial pneumonia (NSIP).6 They reviewed 64 such cases, from which three histological patterns emerged.6 In 48% of the cases, pneumonia was characterised by a cellular interstitial infiltrate with little or no fibrosis (NSIP group I) NSIP was the most frequent in multidisciplinary diagnosis (22 of 33 patients: 67%); of those, fibrotic NSIP was more common than the cellular one. The others were all diagnosed as UIP (11 of 33 patients: 33%), which was not rare in this cohort

  2. e the cellular populations present in lung tissue from patients with NSIP. We first characterized the infiltrate in NSIP in terms of T and B cells, and macrophages, and further identified the T cell population as either CD4 (helper) or CD8 (suppressor-cytotoxic) T cells
  3. NSIP pattern of lung injury, itself further subdivided into cellular and fibrotic NSIP, is the most common pattern of IP in all CTDs except for RA, in which UIP pattern pathology may be more common [41, 42]. NSIP lung injury is characterized by diffuse, although often variable, alveolar septal thickening due to collagen deposition
  4. oacyl tRNA synthetase syndrome with cellular NSIP was diagnosed. She had a favorable response to the initial treatment of methylprednisolone pulse therapy followed by prednisolone 1 mg/kg/day. Her symptoms, pulmonary function test and chest imaging findings have showed improvement after therapy

Cellular non-specific interstitial pneumonia masquerading

In cellular NSIP, the alveolar septa are thickened by infiltrates of lymphocytes and plasma cells, while in fibrotic NSIP the thickening is due to uniform fibrosis of the same age, with varying amounts of cellular inflammation (6,8). Fibrotic NSIP is much more common than cellular NSIP and the extent of interstitial fibrosis is variable (6,79) In neither group were BAL findings predictive of survival or changes in lung function at 1 yr, even after adjustment for disease severity, smoking and treatment. BAL differential counts in fibrotic NSIP differed from respiratory bronchiolitis-associated interstitial lung disease, but not from desquamative interstitial pneumonia or cellular NSIP Patients with nonspecific interstitial pneumonia (NSIP) in all lobes were categorized as having fibrotic (n = 25) or cellular NSIP (n = 5). No consistent distribution of lobar histology was noted. Patients concordant for UIP were older (63 ± 9 [mean ± SD] yr; p < 0.05 as compared with all other groups) than those discordant for UIP (57 ± 12. Cellular NSIP on CT was defined as the presence of ground-glass and/or nodular opacities. Semi-quantitative analysis of fibrosis was performed by certified thoracic radiologist on a free, open-source imaging software (3D Slicer, www.slicer.org) with the Chest Imaging Platform extension Interstitial lung diseases are a group of diffuse parenchymal lung disorders associated with substantial morbidity and mortality. Knowledge achieved in recent years has resulted in the publication of the new classification of idiopathic interstitial pneumonias, according to which there are three groups: major, rare and unclassified. The novelty of the new classification comes from the fact.

  3. The term microcystic honeycombing is used for these cystic changes in NSIP, as opposed to the macrocystic honeycombing seen in UIP. Although the CT features of cellular and fibrotic NSIP overlap considerably, it has been shown that honeycombing is seen almost exclusively in patients with fibrotic NSIP

NSIP further subclassified into cellular or fibrotic types. Readers asked to assess the lung parenchymal abnormalities : ground glass, reticular or mixed. If reticular, they were asked to score the fineness or coarseness of the reticular pattern The prognosis of NSIP is usually significantly better than that of UIP and many patients with NSIP respond well to corticosteroids. The presence of temporal uniformity and absence of fibroblastic foci are helpful in distinguishing NSIP from UIP. NSIP occurs in two variants: 1) a cellular variant without fibroblastic proliferation and fibrosis

A histological analysis showed the cellular pattern in 17 patients (48.6%) and the fibrotic pattern in 10 patients (28.6%); the histological NSIP subtype was indeterminate in eight patients (22.9%). The median follow-up duration for survivors was 55.2 months (range, 15.9-102.0 months) The authors showed that the infant and the adult patients harbored different patterns: cellular thickening and intra-alveolar granular material consistent with cellular NSIP in the infant tissue, compared with a UIP pattern with fibroblast foci, architectural distortion, and metaplastic epithelium in the adult biopsy Pathology • BAL findings do not discriminate between NSIP and UIP and have no prognostic value • When a tissue biopsy is required, VATS is the procedure of choice • 2 groups- 1. Cellular 2. Fibrotic (more common) 19 NSIP is the more commonly encountered histopathologic subtype, comprised of varying degrees of inflammation and fibrosis, with some forms being predominantly inflammatory (cellular NSIP) and others primarily fibrotic (fibrotic NSIP). It remains unclear whether cellular NSIP and fibrotic NSIP represent a progression of one underlying disease.
