Interstitial lung disease (ILD) comprises a heterogeneous group of diffuse parenchymal lung processes with overlapping clinical, radiographic, and histopathologic features. Among the most common and deadly ILDs are idiopathic pulmonary fibrosis (IPF) and chronic hypersensitivity pneumonitis (CHP). As the name implies, the cause of IPF remains elusive, but a variety of genetic and infectious risk factors have been identified. CHP results from chronic inhalation of an organic antigen, usually of avian or mold origin, and may occur in patients with a genetic predisposition...

Diffuse parenchymal lung diseases (DPLDs) encompass a variety of restrictive and obstructive lung pathologies. In this article, the authors discuss a series of rare pulmonary entities and their high-resolution computed tomography imaging appearances, which can mimic more commonly encountered patterns of DPLDs. These cases highlight the importance of surgical lung biopsies in patients with imaging findings that do not show typical imaging features of usual interstitial pneumonia.

Background: Chronic hypersensitivity pneumonitis (HP) is the most common cause of diffuse parenchymal lung disease (DPLD) in India. There is no data regarding the avian antigen exposure-associated DPLD from the country. Methods: Chronic HP from exposure to avian antigen was diagnosed when the high resolution computerized tomography (HRCT) showed features for HP and was supported by the history of exposure to pigeons, the presence of precipitin antibodies (IgG) to avian antigen in high titre with negative rheumatoid factor, antinuclear antibody, and no clinical clue for a collagen vascular disease...

OBJECTIVES: Oesophageal dilatation (OD) has been implicated in the pathogenesis of interstitial lung disease (ILD) in systemic sclerosis (SSc). The aims of this study were to explore the association of the OD and SSc-ILD on chest high-resolution computed tomography (HRCT), and to establish a cutoff point for the OD suggestive for the presence of a significant lung involvement. METHODS: The widest oesophageal diameter (WOD) was obtained on axial HRCT images. The parenchymal abnormalities on HRCT were coded and scored according to Warrick method...

Metal-induced hypersensitivity is driven by T-cell sensitization to metal ions. Although numerous metals are associated with the development of diffuse parenchymal lung disease, beryllium-induced hypersensitivity is the best-studied to date. This review focuses on the interaction between innate and adaptive immunity that leads to the development of chronic beryllium disease. After beryllium exposure, activation of the innate immune system occurs through the engagement of pattern-recognition receptors. This activation leads to cell death, release of alarmins, and activation and migration of dendritic cells to lung-draining lymph nodes...

In pulmonary medicine, identical pathogenesis due to varied etiological agents can present with indistinguishable clinical presentation, and produce similar laboratory and radiological changes. The importance of eliciting detailed occupational and social history from patients cannot be stressed enough when dealing with patients suffering from diffuse parenchymal lung diseases. Hot Tub Lung(HTL) is a perplexing pulmonary disease attributed to the Mycobacterium Avium-intracellulare Complex (MAC). MAC is a ubiquitous atypical mycobacterium present in moist environment, and is not considered pathogenic, without the predisposing conditions like immunosuppression...

A diagnosis of pulmonary sarcoidosis is based on the assessment of clinical outcome, radiology findings and detection of noncaseating granulomas in cytology or histology specimens. Cytological material obtained from enlarged lymph nodes and/or histological specimens from bronchial mucosa and lung tissue are examined according to sarcoidosis stage. The most available are standard bronchoscopic methods as conventional transbronchial needle aspiration (cTBNA), endobronchial biopsy (EBB) and transbronchial lung biopsy (TBLB) both performed with use of forceps...

Interstitial lung diseases (ILD) include a broad range of diffuse parenchymal lung disorders of known and unknown etiologies. Patients with ILD can experience acute exacerbations (AE) which are associated with extremely high morbidity and mortality. Little is known about the etiology of AEs, and whether inciting triggers (such as infection) result in an aberrant inflammatory response in a predisposed host. Areas covered: The majority of data regarding AE-ILD comes from the idiopathic pulmonary fibrosis (IPF) population and is extrapolated to other forms of ILD...

IgG4-related interstitial lung disease (IgG4-RILD), which is characterized by increased IgG4 levels, IgG4+ plasma cell infiltration and irregular whorled fibrosis, is a recently described lung disorder that belongs to the group of systemic fibroinflammatory IgG4-related diseases (IgG4-RD). The aim of the present study was to improve the current knowledge regarding the specific clinical and histopathological characteristics of IgG4-RILD and to investigate its underlying immune mechanism in vivo . A total of 7 patients newly diagnosed with IgG4-RILD were enrolled in the present study (4 men and 3 women; mean age, 57 years; range, 29-71 years)...

Transbronchial cryobiopsies (TBCB) have recently been introduced as a promising and safer alternative to surgical lung biopsy in the diagnostic approach to diffuse parenchymal lung diseases (DPLD). Despite a substantial and expanding body of literature, the technique has not yet been standardized and its place in the diagnostic algorithm of DPLD remains to be defined. In part, this reflects concerns over the diagnostic yield and safety of the procedure, together with the rapid spread of the technique without competency and safety standards; furthermore, there is a substantial procedural variability among centers and interventional pulmonologists...

BACKGROUND: Bronchiolitis obliterans syndrome (BOS) is a leading cause of chronic graft-vs-host disease (cGvHD) and is associated with mortality after allogeneic hematopoietic stem cell transplantation (alloHSCT). The nitrogen multiple breath washout test (N2 -MBW) measures ventilation inhomogeneity, a biomarker of central and peripheral airway obstruction. The aim of this study was to examine ventilation inhomogeneity according to cGvHD score and histologically defined bronchiolitis obliterans (BO)...

Tobacco exposure results in various changes to the airways and lung parenchyma. Although emphysema represents the more common injury pattern, in some individuals, cigarette smoke injures alveolar epithelial cells and other lung cells, resulting in diffuse infiltrates and parenchymal fibrosis. Smoking can trigger interstitial injury patterns mediated via recruitment and inappropriate persistence of myeloid and other immune cells, including eosinophils. As our understanding of the role of cigarette smoke constituents in triggering lung injury continues to evolve, so does our recognition of the spectrum of smoking-related interstitial lung changes...

Introduction: Parameters related to prognosis in diffuse parenchymal lung disease (DPLD) have a decisive influence on treatment and follow-up processes. We aimed to define baseline characteristics and factors that effect the mortality of the group of patients with DPLD and to determine distinctions between subgroups. Materials and Methods: Demographic characteristics, complaints, comorbidity, treatment, pulmonary function tests, echocardiographic findings, six minute walking test (6MWT), arterial blood gases analysis, radiological findings and survival time were collected from outpatient clinics database...

INTRODUCTION: Most data on transbronchial lung cryobiopsy (TBLC) are from single centers, with little evidence on the outcome of different methods for performing TBLC. OBJECTIVE: To report the diagnostic yield and safety of TBLC with different procedural techniques. MATERIALS AND METHODS: Retrospective multicenter study of subjects who underwent TBLC for the diagnosis of diffuse parenchymal lung diseases (DPLDs). The procedure was performed using various methods: flexible or rigid bronchoscopy, with or without the use of fluoroscopy or occlusion balloon...
