OBJECTIVES: We aimed to assess the clinical significance of Krebs von den Lungen-6 (KL-6) in the diagnosis and severity of interstitial lung disease (ILD) in a French cohort of patients with systemic sclerosis (SSc). METHODS: Serum KL-6 concentrations were measured with chemiluminescent enzyme immunoassay (CLEIA) in 75 SSc patients. Patients were divided into two groups according to the presence of interstitial lung disease (SSc-ILD versus SSc-without ILD) on chest High-Resolution Computed Tomography...

Indium oxide (In 2 O 3 ) is a technologically important semiconductor essentially used, doped with tin oxide, to form indium tin oxide (ITO). It is poorly soluble in all so far tested physiologic media. After repeated inhalation, In 2 O 3 particles accumulate in the lungs. Their mobilization can cause significant systemic exposure over long periods of time. An increasing number of cases of severe lung effects (characterized by pulmonary alveolar proteinosis, emphysema and/or interstitial fibrosis) in workers of the ITO industry warrants a review of the toxicological hazards also of In 2 O 3 ...

OBJECTIVES: High-resolution computed tomography (HRCT) parenchymal patterns have been used to predict prognosis in patients with interstitial lung disease (ILD). In idiopathic pulmonary fibrosis, the fibrosis score (i.e., the combined extent of reticulation and honeycombing) has been associated with worse survival. This study aimed to identify HRCT patterns and patient characteristics that can predict poor prognosis in rheumatoid arthritis-related ILD (RA-ILD). METHODS: We retrospectively analysed 65 patients with newly diagnosed RA-ILD from 2007 to 2016 at Kurashiki Central hospital...

OBJECTIVES: Systemic sclerosis (SSc) is a chronic, inflammatory, and autoimmune connective tissue disease that is associated with vascular lesions, and fibrosis of the skin and visceral organs. Cardiac complications may occur as a secondary effect of SSc as a result of pulmonary arterial hypertension and interstitial lung disease. The objective of this study was to assess whether the pulmonary pulse transit time (pPTT) could serve as a diagnostic marker for pulmonary arterial alterations in patients with SSc, prior to development of pulmonary hypertension...

The histologic manifestation of idiopathic pulmonary fibrosis (IPF) is usual interstitial pneumonia (UIP), which is a good prognostic determinant of survival compared with other histologic interstitial lung disease patterns. According to the current international guidelines, the histologic features of suspected IPF/UIP are divided into 4 categories: UIP, probable UIP, possible UIP, and not UIP pattern. Four pulmonary pathologists who were blinded to clinicoradiologic information reevaluated 50 surgical lung biopsies (83...

AIMS: Autoimmune conditions such as rheumatoid arthritis-related interstitial lung disease (RA-ILD) have been linked to the existence of emphysema in never-smokers. We aimed to quantify emphysema prevalence in RA-ILD never-smokers and investigate whether combined pulmonary fibrosis and emphysema (CPFE) results in a worsened prognosis independent of baseline disease extent. METHODS: RA-ILD patients presenting to the Royal Brompton Hospital (n=90) and Asan Medical Center (n=155) had CT's evaluated for a definite usual interstitial pneumonia (UIP) pattern, and visual extents of emphysema and ILD...

BACKGROUND: Mortality is similarly high among individuals with usual interstitial pneumonia (UIP) due to idiopathic pulmonary fibrosis (IPF) and interstitial pneumonia with autoimmune features (IPAF). Circulating anti-nuclear antibodies (ANA) are commonly found in this patient population, suggesting possible aberrant immune activation. Because an environment of oxidative stress can result from immunologic activation, we hypothesized that ANA positive patients with UIP would have improved outcome when exposed to the antioxidant N-acetylcysteine (NAC) compared to ANA negative patients...

Background: Interstitial lung diseases are diseases that need histology diagnosis or obtaining a lung biopsy to establish the diagnosis. Surgical biopsies are performed usually using the thoracoscopy technique under general anesthesia (GA) although this procedure is still associated with morbidity rate. The aim of this study is to determine the effectiveness and safety of regional anesthesia (RA) compared with GA in thoracoscopic lung biopsy procedures done on patients with idiopathic pulmonary fibrosis (IPF)...

BACKGROUND: Pre-flight risk assessments are currently recommended for all Interstitial Lung Disease (ILD) patients. Hypoxic challenge testing (HCT) can inform regarding the need for supplemental in-flight oxygen but variables which might predict the outcome of HCT and thus guide referral for assessment, are unknown. METHODS: A retrospective analysis of ILD patients attending for HCT at three tertiary care ILD referral centres was undertaken to investigate the concordance between HCT and existing predictive equations for prediction of in-flight hypoxia...

The incidence and risk factors of lung cancer in patients with idiopathic pulmonary fibrosis (IPF) have been poorly investigated. We conducted a retrospective study of 632 patients with IPF to assess the incidence and risk factors of lung cancer development. Seventy patients developed lung cancer over a median follow-up period of 3.8 years. The incidence density of lung cancer development was 25.2 cases per 1000 person-years. The most frequent type was squamous cell carcinoma (30%), the majority developed lung cancer in the peripheral lung (82...

Berberine has been demonstrated to alleviate renal interstitial, liver and myocardial fibrosis when administered orally despite its extremely low bioavailability. Here, we inspected effect of berberine on pulmonary fibrosis (PF) and explored underlying mechanisms on the basis of intestinal endocrine. The results showed that either oral or rectal administration of berberine exhibited marked alleviation of bleomycin-induced PF in mice. In contrast, anti-PF activity of berberine disappeared when given by an intravenous injection, implying that it functioned in a gut-dependent manner...

Platelet-derived growth factor (PDGF) was discovered as a serum-derived component necessary for the growth of smooth muscle cells, fibroblasts, and glial cells. The PDGF family is a product of four gene products and consists of five dimeric isoforms: PDGF-AA, PDGF-BB, PDGF-CC, PDGF-DD, and the PDGF-AB heterodimer. This growth factor family plays an essential role in embryonic development and in wound healing in the adult. These growth factors mediate their effects by binding to and activating their receptor protein-tyrosine kinases, which are encoded by two genes: PDGFRA and PDGFRB...

Idiopathic pulmonary fibrosis (IPF) is a chronic, debilitating, fibrotic lung disease leading to respiratory failure and ultimately to death. Being the prototype of interstitial lung diseases, IPF is characterized by marked heterogeneity regarding its clinical course. Despite significant progress in the understanding of its pathogenesis, we still cannot reliably predict the course of the disease and the response to treatment of an individual patient. Non-invasive biomarkers, in particular serum biomarkers, for the (early) diagnosis, differential diagnosis, prognosis and prediction of therapeutic response are urgently needed...

BACKGROUND: We hypothesise, based upon the findings from our previous trial, that the addition of co-trimoxazole to standard therapy is beneficial to patients with moderate to severe idiopathic pulmonary fibrosis (IPF). We aim to investigate this by assessing unplanned hospitalisation-free survival (defined as time from randomisation to first non-elective hospitalisation, lung transplant or death) and to determine whether any effect relates to changes in infection and/or markers of disease control and neutrophil activity...

Idiopathic pulmonary fibrosis (IPF) is a fibrosing interstitial lung disease associated with debilitating symptoms of dyspnoea and cough, resulting in respiratory failure, impaired quality of life and ultimately death. Diagnosing IPF can be challenging, as it often shares many features with other interstitial lung diseases. In this article, we summarise recent joint position statements on the diagnosis and management of IPF from the Thoracic Society of Australia and New Zealand and Lung Foundation Australia, specifically tailored for physicians across Australia and New Zealand...

Familial pulmonary fibrosis is associated with loss-of-function mutations in telomerase reverse transcriptase (TERT) and short telomeres. Interstitial lung diseases have become the leading indication for lung transplantation in the USA, and recent data indicate that pathogenic mutations in telomerase may cause unfavourable outcomes following lung transplantation. Although a rare occurrence, solid organ transplant recipients who develop acute graft-versus-host disease (GVHD) have very poor survival. This case report describes the detection of a novel mutation in TERT in a patient who had lung transplantation for familial pulmonary fibrosis and died from complications of acute GVHD...

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) differs substantially from other idiopathic interstitial pneumonias regarding disease trajectory and the appropriate management strategies, making meticulous diagnosis essential. However, patient characteristics and clinical practice vary between clinical trials, and real life and registries provide the opportunity to critically analyse current clinical practices in order to ultimately improve patient care. METHODS: We aimed to identify characteristics of our baseline IPF cohort at initiation of a web-based registry for patients with idiopathic interstitial pneumonia...

There is an increasing recognition of patients with radiologic features of both pulmonary fibrosis and emphysema. This association has enabled the description of a syndrome termed combined pulmonary fibrosis and emphysema (CPFE) with unique features. Patients are mostly male smokers who suffer from effort dyspnea and hypoxemia, with near-normal spirometric and lung volumes measurements, and abnormalities of gas exchange. On the computerized tomography there is upper-lobe emphysema and lower-lobe interstitial fibrosis...
