Smoking-related interstitial fibrosis

Seth Kligerman, Teri J Franks, Jeffrey R Galvin
The direct toxicity of cigarette smoke and the body's subsequent response to this lung injury leads to a wide array of pathologic manifestations and disease states that lead to both reversible and irreversible injury to the large airways, small airways, alveolar walls, and alveolar spaces. These include emphysema, bronchitis, bronchiolitis, acute eosinophilic pneumonia, pulmonary Langerhans cell histiocytosis, respiratory bronchiolitis, desquamative interstitial pneumonia, and pulmonary fibrosis. Although these various forms of injury have different pathologic and imaging manifestations, they are all part of the spectrum of smoking-related diffuse parenchymal lung disease...

OBJECTIVE: To differentiate smoking-related interstitial fibrosis (SRIF) from usual interstitial pneumonia (UIP) with emphysema on CT in combined pulmonary fibrosis and emphysema (CPFE) patients. MATERIALS AND METHODS: This study was approved by the institutional review board and informed consent was waived. We included 65 patients who underwent lung biopsy under the suspicion of UIP pattern on HRCT, and after radiologic-pathologic correlation, they were divided into three groups: UIP without emphysema (n = 30), UIP with emphysema (n = 26), and SRIF (n = 9)...

AIMS: There have been few reports on immunoglobulin-G4 (IgG4)-related interstitial pneumonia (IP), and its clinical features remain unclear. The objective of this study was to assess whether IP with marked IgG4-positive plasma cell infiltration without extrathoracic lesions of IgG4-related disease (RD) should be diagnosed as a subtype of IgG4-RD or a separate entity. METHODS AND RESULTS: All consecutive patients with surgical lung biopsy-proven idiopathic IP with an IgG4/IgG-positive cell ratio of >40% and >50 IgG4(+) plasma cells in a high-power field without extrathoracic lesions of IgG4-RD were reviewed retrospectively...

There is increased awareness of smoking-related lung diseases other than lung cancer and chronic obstructive pulmonary disease. Concurrently, there is general acceptance that there is difficulty in establishing a specific diagnosis of smoking-related interstitial lung disease (ILD), as many patients may not undergo biopsy to facilitate a specific histopathologic diagnosis. Cases that do proceed to biopsy may demonstrate multiple abnormalities, and histologic overlap between different disease processes may confound the picture...

In the updated American Thoracic Society-European Respiratory Society classification of the idiopathic interstitial pneumonias (IIPs), the major entities have been preserved and grouped into (a) "chronic fibrosing IIPs" (idiopathic pulmonary fibrosis and idiopathic nonspecific interstitial pneumonia), (b) "smoking-related IIPs" (respiratory bronchiolitis-associated interstitial lung disease and desquamative interstitial pneumonia), (c) "acute or subacute IIPs" (cryptogenic organizing pneumonia and acute interstitial pneumonia), and (d) "rare IIPs" (lymphoid interstitial pneumonia and idiopathic pleuroparenchymal fibroelastosis)...

For many years, cigarette smoking has been considered as the leading cause of chronic obstructive pulmonary disease and lung cancer. Recently, however, it has also been associated with the development of diffuse interstitial lung diseases. In the latest classification of the major idiopathic interstitial pneumonias (IIP), the term smoking-related IIP has been introduced, including two entities, namely desquamative interstitial pneumonia (DIP) and respiratory bronchiolitis-interstitial lung disease (RB-ILD)...

OBJECTIVE: To evaluate whether serum titers of second-generation anticyclic citrullinated peptide antibodies (anti-CCP2) are associated with the severity and extent of interstitial lung disease in rheumatoid arthritis (RA-ILD). METHODS: In across-sectional study, 39 RA-ILD patients confirmed by high-resolution computed tomography (HRCT) were compared with 42 RA without lung involvement (RA only). Characteristics related to RA-ILD were assessed in all of the patients and serum anti-CCP2 titers quantified...

In 2008, Kawabata et al. described a lesion which they termed "airspace enlargement with fibrosis" that could be included on the spectrum of smoking-related interstitial lung diseases. This group also reported that patients with airspace enlargement with fibrosis but without coexisting interstitial pneumonia of another type had no acute exacerbations and favorable prognoses on clinical follow-up. Here we describe the first case, to our knowledge, of acute exacerbation of airspace enlargement with fibrosis without coexisting interstitial pneumonia of another type...

PURPOSE OF REVIEW: To discuss the imaging of interstitial lung disease believed to be caused by smoking. RECENT FINDINGS: It is increasingly clear that smoking is associated with a variety of patterns of interstitial lung disease. The radiologic features of interstitial lung disease caused by smoking cigarettes are variable and may be nonspecific. SUMMARY: It is now accepted that cigarette smoking can cause lung diseases other than lung cancer, chronic bronchitis and emphysema...

The use of high-resolution computed tomography (HRCT) has brought increased diagnostic discrimination to the evaluation of lung disease, particularly fibrosing lung diseases. Once the presence of a predominantly fibrosing lung disease has been established on evaluation of a HRCT, a stepwise approach is proposed that can refine the potential HRCT diagnoses from a list of over 100 different interstitial lung diseases to one of only five fibrosing lung diseases. Within the category of the fibrosing lung diseases, the recognition of idiopathic pulmonary fibrosis (IPF) is key...

BACKGROUND: Smoking-related interstitial lung diseases (SR-ILDs) are a heterogeneous group of diseases with major clinical significance. Reliable epidemiological data are not yet available. METHOD: Review of pertinent literature retrieved by a selective search in PubMed. RESULTS: The available data on many aspects of SR-ILDs are sparse, but recent studies on the pathophysiology and targeted treatment of these conditions have revealed ways in which clinical outcomes can be improved...

The adaptor protein p66Shc regulates intracellular oxidant levels through the modulation of a forkhead-related transcription factor (FOXO3a). The genetic ablation of p66Shc (p66Shc-/-) renders mice resistant to oxidative stress and p53-dependent apoptosis. We investigated whether p66Shc ablation in mice modifies lung cellular and molecular responses to cigarette smoke (CS) exposure. No differences between wild type (WT) and p66Shc-/- mice were observed in terms of inflammation and oxidant burden after acute CS exposure; however,p66Shc ablation modifies specific features of chronic inflammation induced by repeated exposure to CS...

PURPOSE: Airspace enlargement with fibrosis (AEF) has been identified pathologically as a smoking related change. We sought to identify the HRCT findings of AEF and search for distinguishing features from honeycombing. MATERIALS AND METHODS: 50 patients (47 males; mean age 69) were evaluated. All had undergone lobectomy for lung cancer and had confirmed AEF and/or usual interstitial pneumonia (UIP) by pathological evaluation. HRCT findings were first evaluated preresection for resected lobes, and then correlated with the subsequent pathological findings in the resection specimens...

BACKGROUND: Chronic smoking and hypertension may lead to smoking-related nodular glomerulopathy (SRNG), a well-recognized entity that clinically and pathologically mimics nodular diabetic nephropathy (DN). However, like DN, diffuse mesangial sclerosis may occur in this setting without nodules. METHODS: The clinicopathologic features of 10 non-diabetic patients with a long smoking history diagnosed from 2003-2012 showing diffuse mesangial glomerulosclerosis (6) or SRNG (4) were analyzed...

The diagnosis of pulmonary asbestosis is most often established based on clinical criteria and has both clinical and legal implications. Unfortunately, one of the confounding features in the diagnosis may be a history of cigarette abuse, which can produce interstitial opacities on chest imaging as well as diffusion defects on pulmonary function testing, criteria that are used in the diagnosis of pulmonary asbestosis. The objective of the present study was to evaluate the correlation of radiographically detected pulmonary fibrosis with fibrosis established histopathologically as attributable to asbestos, in a cohort referred for diagnosis of an asbestos-related malignancy in the context of litigation...

INTRODUCTION: Desquamative interstitial pneumonia is one of the rarest idiopathic interstitial pneumonias and the rarest form of smoking-related interstitial lung diseases. It was first described by Liebow in 1965. Histologically, it is characterized by the presence of eosinophilic macrophages uniformly filling airspaces which often contain a finely granular light-brown pigment that does not stain for hemosiderin. The alveolar walls are usually mildly thickened by fibrous tissue and infiltrated by a moderate number of lymphocytes...
