CONTEXT: - Chronic hypersensitivity pneumonitis (CHP) has emerged from obscurity during the past 15 years and is now recognized as a very common form of fibrosing interstitial pneumonia but one that is frequently misdiagnosed both clinically and on surgical lung biopsy as usual interstitial pneumonia/idiopathic pulmonary fibrosis (UIP/IPF) or fibrotic nonspecific interstitial pneumonia. OBJECTIVE: - To review the pathologic features of CHP. DATA SOURCES: - Clinical, pathology, and radiology literature were used...

OBJECTIVES: The purpose of our study was to assess proton density (PD) and T2 relaxation time of usual interstitial pneumonia (UIP) and nonspecific interstitial pneumonia (NSIP) and to evaluate their utility in differentiating the two patterns. Furthermore, we aim to investigate whether these two parameters could help differentiate active-inflammatory and stable-fibrotic lesions in NSIP. METHODS: 32 patients (mean age: 69 years; M:F, 1:1) with pathologically proven disease (UIP:NSIP, 1:1), underwent thoracic thin-section multislice CT scan and 1...

BACKGROUND AND OBJECTIVE: Lobar and temporal histological variability in chronic bird-related hypersensitivity pneumonitis (BRHP) has not been clearly elucidated. This study was designed to evaluate the spatio-temporal histopathological variability in chronic BRHP. METHODS: Fifty-two patients with chronic BRHP who underwent a surgical lung biopsy (SLB) between 1992 and 2008 were evaluated. The histopathological characteristics of the lung biopsy specimens were classified by the 2002 American Thoracic Society/European Respiratory Society (ATS/ERS) consensus classification of idiopathic interstitial pneumonias (IIPs)...

BACKGROUND: Rheumatoid arthritis-associated interstitial lung disease (RA-ILD) is associated with significant morbidity and mortality. Similarities have been observed between patients with idiopathic pulmonary fibrosis (IPF) and the UIP (usual interstitial pneumonia) form of RA-ILD. The GAP (gender, age, physiology) model has been shown to predict mortality in patients with IPF, but its ability to predict mortality in RA-ILD is not known. METHODS: We identified 309 patients with RA-ILD at 4 academic centers with ongoing longitudinal cohorts of patients with ILD...

Despite its high prevalence and mortality, little is known about the pathogenesis of rheumatoid arthritis-associated interstitial lung disease (RA-ILD). Given that familial pulmonary fibrosis (FPF) and RA-ILD frequently share the usual pattern of interstitial pneumonia and common environmental risk factors, we hypothesised that the two diseases might share additional risk factors, including FPF-linked genes. Our aim was to identify coding mutations of FPF-risk genes associated with RA-ILD.We used whole exome sequencing (WES), followed by restricted analysis of a discrete number of FPF-linked genes and performed a burden test to assess the excess number of mutations in RA-ILD patients compared to controls...

OBJECTIVE: Since the prognosis after standard lobectomy for non-small cell lung cancer (NSCLC) in patients with interstitial lung disease (ILD) is poor, we investigated the possibility of sublobar resection for the improvement of the surgical results in such patients. METHODS: Of 796 consecutive patients with clinical stage I NSCLC who underwent pulmonary resection, 107 were diagnosed with ILD using high-resolution computed tomography (HRCT). Overall survivals (OS) were compared between patients with non-ILD and those with ILD or between patients with ILD who underwent lobectomy and those who underwent sublobar resection...

As seen in this CME online activity (available at http://courses.elseviercme.com/chest16/647e), idiopathic pulmonary fibrosis (IPF) is a specific form of chronic progressive fibrotic lung disease of unknown cause. It is the most common form of idiopathic interstitial pneumonia in adults. Its prevalence among US Medicare beneficiaries has more than doubled in the past 14 years. With the approval of two agents that reduce functional decline and disease progression, and the 2015 update of the American Thoracic Society guidelines on the treatment of IPF, the options for appropriate clinical management of the disease have become well defined...

Objective.: To evaluate the effect of rituximab (RTX) in patients with RA-related interstitial lung disease (RA-ILD) and identify factors associated with outcome after treatment. Methods.: An observational study of patients with RA-ILD was conducted from a cohort of RTX-treated RA patients in a single centre for >10 years. Progression was defined by any of the following: a decrease of pre-RTX forced vital capacity (FVC) >10% or diffusion capacity of carbon monoxide (DLCO) >15% predicted, worsening of the ILD score or death from progressive ILD...

BACKGROUND: Clinically amyopathic dermatomyositis (CADM) is a distinct subgroup of dermatomyositis characterized by unique dermatologic manifestations without muscle involvement. CADM is frequently associated with interstitial lung disease (ILD), which usually has a rapidly progressive, fatal clinical course. Although CADM-related ILD (CADM-ILD) is well-described, data on the histopathology of CADM-ILD are limited. Organizing pneumonia and pulmonary vasculitis have rarely been reported...

A 71-year-old man was admitted to our hospital for dyspnea, which had worsened over a period of more than six months. He was previously diagnosed as having cryptogenic organizing pneumonia, and was treated with steroids in another hospital. He had complained of worsening dyspnea, despite the treatment. We performed video-assisted thoracoscopic surgery because of the high level of lactate dehydrogenase and inconsistency of the usual interstitial pneumonia pattern. Pathologic specimens showed atypical lymphocytes confined to the pulmonary capillaries...

BACKGROUND Idiopathic inflammatory myopathies are autoimmune disorders that can involve the skin, joints, muscles, and lungs. The most common of these disorders are dermatomyositis, polymyositis, overlap syndrome, and inclusion body myositis. Necrotizing autoimmune myopathy is an idiopathic inflammatory myopathy that is rarely associated with Sjögren's syndrome. The most common lung findings associated with anti-EJ antisynthetase syndrome are nonspecific interstitial pneumonia and usual interstitial pneumonia; this condition is rarely associated with fibrinous and organizing pneumonia...

Cough is one of the most common symptoms that doctor faces in working with pediatric population, and according to some characteristics of cough, doctors can often conclude localization, and sometimes even the nature of the disease that causes it. Cough is not only the physiological defense reaction, but a symptom of a disease. According to duration it can be acute, chronic and recidivist, recurrent and persistent, strong or discreet, caused by changes in body position and changes in outside temperature. Pathoanatomically it is divided into lobar, lobular, alveolar and interstitial, pathogenetically to bronchogenic and hematogenous, as well as in immuno competent and immunocompromised, and clinically on the local and inpatient (72 hours after hospital admission)...

This study of twelve patients focused on a variant of cryptogenic organizing pneumonia (COP) labeled the cicatricial form in which the airspaces of the lung are filled with and consolidated by dense collagenized scar tissue associated with preservation of underlying lung architecture. Patients were predominantly middle aged men and presented with bilateral lung disease in the majority of cases, often with nodular or reticulonodular disease (10/12; 83%). Patients were usually symptomatic with shortness of breath, cough, and dyspnea on exertion...

BACKGROUND Chronic Granulomatous Disease (CGD) is a rare immunodeficiency disease caused by a genetic defect in the NADPH (nicotinamide adenine dinucleotide phosphate) oxidase enzyme, resulting in increased susceptibility to bacterial and fungal infections. The inheritance can be X-linked or autosomal recessive. Patients usually present with repeated infections early in life. We present an unusual case of a 23-year-old patient diagnosed with CGD. CASE REPORT A 23-year-old white woman with no previous history of recurrent infections presented with complaints of fever, shortness of breath, and diffuse myalgia...

Primary Sjögren syndrome (pSS)-related interstitial lung disease (ILD) involved about 10-20% of patients. In 20% of cases, ILD can be diagnosed before pSS; anyway, few studies have investigated the frequency of ILD as the first clinically relevant manifestation of pSS, generally referred to retrospective studies. Aim of our prospective study was to describe prevalence, clinical, serological, and instrumental features of non-sicca onset pSS patients with interstitial lung involvement. During a period of 48 months, all consecutive patients diagnosed as pSS were enrolled...

BACKGROUND: Current understanding of human immunodeficiency virus (HIV)-associated pulmonary cryptococcosis (PC) is largely based on studies performed about 2 decades ago which reported that the most common findings on chest radiograph were diffuse interstitial infiltrates. Few studies are available regarding the computed tomography (CT) findings. The aim of this study was to characterize chest CT features of HIV-associated PC. METHODS: HIV patients with cryptococccal infection and pulmonary abnormalities on Chest CT between September 2010 and May 2016 in the Second Affiliated Hospital of the Southeast University were retrospectively analyzed...

Usual interstitial pneumonia (UIP) is characterized by progressive scarring of the lungs and is associated with high morbidity and mortality despite therapeutic interventions. Sex steroid receptors have been demonstrated to play an important role in chronic lung conditions; however, their significance is unknown in patients with UIP. We retrospectively reviewed 40 idiopathic UIP cases for the expression of hormonal receptors. Forty cases including 10 normal lung, 10 cryptogenic organizing pneumonia (COP), 10 idiopathic organizing diffuse alveolar damage (DAD), 7 hypersensitivity pneumonitis (HP) and 3 nonspecific interstitial pneumonitis (NSIP) served as controls...
