nonspecific interstitial pneumonia

Since its confirmation in Wuhan, Hubei Province, China, at the end of 2019, the novel coronavirus disease (COVID-19) has rapidly spread worldwide in multiple epidemic waves while undergoing mutations. To date, numerous individuals have been infected. Symptoms range from asymptomatic and common cold-like to acute respiratory failure and acute respiratory distress syndrome (ARDS), which can lead to death. Here, we present the case of an 81-year-old woman with a fever that persisted for more than five days after infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)...

Interstitial pneumonia often acts as a barrier to lung cancer treatment. We report the case of a 79-year-old man who was diagnosed with epidermal growth factor receptor (EGFR) mutation positive lung adenocarcinoma (T2aN0M0, stage ⅠB, EGFR exon 19 deletion), and was positive for anti-aminoacyl-tRNA synthetase antibodies with interstitial pneumonia. Metastasis in the right seventh rib was detected three months after surgical resection and radiation therapy was initiated. As recurrence was observed at both ends of the radiation field five months later, combination chemotherapy with erlotinib and ramucirumab was initiated...

Background  Decisions on the management of interstitial lung diseases (ILD) and prognostication require an accurate diagnosis. It has been proposed that multidisciplinary team (MDT) meetings for ILD (ILD-MDT) improve these decisions in challenging cases of ILD. However, most studies in this field have been based on the decisions of individual clinicians and there are few reports on the outcomes of the ILD-MDT approach. We therefore describe the experience of the ILD-MDT meetings at our institution. Methods  A single-center retrospective review of the electronic health care records of patients discussed in the ILD-MDT meetings at our institution from February 2016 to January 2021 was performed...

OBJECTIVES: To explore clinical and laboratory characteristics of primary Sjögren's syndrome (pSS) complicated with interstitial lung disease (ILD) and investigate the risk factors for respiratory infections in pSS-ILD. METHODS: A cohort of 162 pSS-ILD patients in Peking University People's Hospital from 2015 to 2020 were included, and all medical records were completely collected. We screened 53 patients suffering from respiratory infections as study cases, compared with 109 age- and sex-matched controls...

Interstitial lung disease (ILD) frequently complicates mixed connective tissue disease (MCTD) and contributes to increased mortality. We aimed to identify predictors of ILD in MCTD patients. This is a nationwide, multicentre, retrospective study including patients with an adult-onset MCTD clinical diagnosis who met Sharp's, Kasukawa, Alarcón-Segovia, or Kahn's diagnostic criteria and had available chest high-resolution computed tomography (HRCT) data. Univariate and multivariate analyses were conducted...

BACKGROUND: Early identification of fibrotic interstitial lung disease (F-ILD) patients with high risk of progression will help initiate early therapeutic intervention and potential improvement of outcomes. This study was designed to assess the predictors of progression in patients with F-ILD. METHODS: Patients with F-ILD in Shanghai Pulmonary Hospital between January 1, 2019 and July 31, 2021 were retrospectively analyzed. The patients enrolled were divided into progressive group and non-progressive group according to the specified criteria...

RATIONALE: Acute fibrinous and organizing pneumonia (AFOP) is a rare acute or subacute interstitial lung disorder characterized by the deposition of fibrin within the alveoli and organizing pneumonia with a patchy distribution. The clinical features of AFOP are nonspecific, and it is often misdiagnosed as pneumonia, cancer, tuberculosis, or other lung disorders. PATIENT CONCERNS: In this case report, a 58-year-old woman presented with chest tightness, shortness of breath, cough and sputum...

Interstitial lung disease and airway disease (AD) are often complicated with rheumatoid arthritis (RA) and have a poor prognosis. Several studies reported genetic associations with interstitial lung disease in RA. However, few genetic studies have examined the susceptibility to AD in RA patients. Here, we investigated whether single nucleotide variants susceptible to idiopathic pulmonary fibrosis might be associated with interstitial lung disease or AD in Japanese RA patients. Genotyping of rs2736100 [C/A] in TERT and rs1278769 [G/A] in ATP11A was conducted in 98 RA patients with usual interstitial pneumonia, 120 with nonspecific interstitial pneumonia (NSIP), 227 with AD, and 422 without chronic lung disease using TaqMan assays...

BACKGROUND: The INBUILD study demonstrated the efficacy of nintedanib in the treatment of progressive fibrosing interstitial lung disease different to idiopathic pulmonary fibrosis, including rheumatoid arthritis (RA)-related ILD. Nevertheless, the prevalence of RA-ILD patients that may potentially benefit from nintedanib remains unknown. OBJECTIVES AND METHODS: The aim of the present multicentre study was to investigate the prevalence and possible associated factors of fibrosing progressive patterns in a cross-sectional cohort of RA-ILD patients...

A 72-year-old man presented with bilateral ground-glass opacities in the lower lung fields on chest radiography. Computed chest tomography showed ground-glass opacities and micronodules in both lower lungs. A video-assisted thoracoscopic biopsy of the right lower lung showed homogeneous thickening of the alveolar septa with fibrosis and inflammatory cell infiltration consistent with fibrotic non-specific interstitial pneumonia (fNSIP). Cicatricial organizing pneumonia and intraluminal pulmonary ossification containing bone marrow that was considered to represent dendriform pulmonary ossification...

BACKGROUND: "Interstitial lung disease" (ILD) is a broad term encompassing diseases of different backgrounds. "Interstitial pneumonia with autoimmune features" (IPAF) is a recent term that implies the presence of autoimmunity. OBJECTIVE: This study aims to determine the characteristics of Polish patients with IPAF, compare them with patients with other interstitial pneumonias, and search for the prognostic and diagnostic biomarkers of IPAF in serum and bronchoalveolar lavage fluid (BALF)...

INTRODUCTION: To investigate the feasibility of early surgical treatment and perioperative steroid use in patients with interstitial lung disease (ILD) complicated by pneumothorax. METHODS: We retrospectively examined data, including patient characteristics, laboratory findings, surgical treatment details, postoperative complications, and deaths, of nine patients with ILD complicated by secondary pneumothorax. The patients had been treated at our hospital during the past 10 years...

Eosinophilia with pulmonary involvement is characterized by the presence of peripheral blood eosinophilia, typically >500 cells/mm3, nonspecific pulmonary symptoms, and radiographic evidence of pulmonary disease. Clinical, laboratory, and radiologic features can be overlapping in these diseases, thus, it is wise to approach eosinophilia with pulmonary involvement systematically to determine the diagnosis and provide definitive treatment for a better outcome. The authors present a case of idiopathic chronic eosinophilic pneumonia in a patient with a long history of chronic obstructive pulmonary disease (COPD) which was resolved by corticosteroid...

COPA syndrome is a recently described autosomal dominant inborn error of immunity characterized by high titer autoantibodies and interstitial lung disease, with many individuals also having arthritis and nephritis. Onset is usually in early childhood, with unique disease features including alveolar hemorrhage, which can be insidious, pulmonary cyst formation, and progressive pulmonary fibrosis in nonspecific interstitial pneumonia or lymphocytic interstitial pneumonia patterns. This review explores the clinical presentation, genetics, molecular mechanisms, organ manifestations, and treatment approaches for COPA syndrome, and presents a diagnostic framework of suggested indications for patient testing...

The clinic and pathological anatomy of the infection caused by the SARS-CoV-2 virus (coronavirus infection - CI) with the development of Post-Covid syndrome (PS) have not been studied enough. This also applies to morphofunctional changes in the lungs, one of the most important components of PS. We conducted a histological and bacterioscopic study of lung biopsy specimens in 20 patients of both sexes aged 22-75 years. In many patients, PS developed relatively late - not earlier than 1 year - 1 year 4 months after the onset of acute clinical symptoms of CI...

Background and Objectives: Recently published articles reported an association between psoriasis and interstitial lung diseases (ILDs). The aim of this study is to evaluate the differences in ILD computed tomography (CT) patterns between smoker and never smoker plaque psoriasis (PP) patients under topical treatment without psoriatic arthritis (PA), inflammatory bowel disease (IBD) or connective tissue diseases (CTDs). Matherials and Methods : Two radiologists evaluated chest CT examinations of 65 patients (33 smokers, 32 never smokers) with PP...

We report 13 cases of pulmonary pneumocystis (PCP) in human immunodeficiency virus (HIV)-uninfected patients. Of eight males and five females, with a mean age of 55 years, one had breast neoplasia, two had common variable immunodeficiency (CVID), one had an autoimmune disease "Goodpasture's syndrome", and one had idiopathic fibrosis (nonspecific interstitial pneumonia/fibrosis (NIP)) undergoing prolonged corticosteroid therapy for two years, with no known immunosuppression in the remaining cases. The clinical picture was characterized by constant dyspnea and severe hypoxia in 11 cases...

BACKGROUND: Uncontrolled T-cell activation plays a key role in systemic sclerosis (SSc). Arsenic trioxide (ATO) has immunological effects and has demonstrated potential in preclinical SSc models. In this study, we assessed the efficacy of ATO in Fra2 transgenic (Fra2TG ) mice, which develop severe vascular remodeling of pulmonary arterioles and nonspecific interstitial pneumonia-like lung disease, closely resembling human SSc-associated pulmonary hypertension, therefore partially resembling to the SSc human disease...

Idiopathic inflammatory myopathies are rare systemic diseases with different types of pulmonary manifestations depending on the underlying aetiology; here, interstitial lung diseases (ILD) are the most frequently found patterns depending on the underlying disorder. There is a lack of sufficient prospective studies on this heterogeneous group of patients, particularly in case of ILD being involved. The diagnosis is based upon guideline recommendations for ILD and requires a multidisciplinary discussion within a team with specific expertise in this field...

INTRODUCTION: Interstitial lung disease (ILD) can manifest before the diagnosis of primary Sjögren's syndrome (pSS), however, the underlying mechanisms remain unclear. The aim of this study is to investigate the characteristics of lung-onset pSS using chest high-resolution computerized tomography (HRCT) and pulmonary function tests (PFTs). METHODS: The data of 102 patients with pSS-ILD were retrospectively analyzed. The patients were divided into two groups: lung-onset group and the nonlung-onset group...
