Inflammation is a central contributor to the pathogenesis of cystic fibrosis (CF) pulmonary disease; so limiting the excessive production of inflammatory mediators represents a major therapeutic strategy for slowing the decline in lung function and improving survival. The macrolide antibiotic azithromycin (AZM) has anti-inflammatory properties and immunomodulatory effects that may be beneficial in CF. The aim of this study was to document the long term use of AZM effect on pulmonary function, nutritional status and number of pulmonary exacerbations in patients with CF...

BACKGROUND: Amiodarone is associated with a number of significant adverse effects, including elevated transaminase levels, pulmonary fibrosis, arrhythmia, and thyroid dysfunction. Although thyroid dysfunction is considered to be a common and potentially serious adverse effect of amiodarone therapy, the exact pathogenesis remains unknown because of its complex manifestations. Therefore, the prevalence of, and risk factors for, amiodarone-induced thyroid dysfunction in Japanese patients were investigated in the present study...

INTRODUCTION AND BACKGROUND: Patients with chronic lung diseases frequently have depressive and anxiety symptoms, but there are very few studies looking at this in patients with bronchiectasis. AIM: This study aimed to investigate depression and anxiety and related factors among patients with non-cystic fibrosis bronchiectasis. PATIENTS AND METHODS: This was a prospective study of 133 patients with bronchiectasis. Patients with confirmed diagnosis of bronchiectasis with high-resolution computed tomography were enrolled in the study...

BACKGROUND: While exercise testing is increasingly used as a prognostic indicator in cystic fibrosis (CF), it is reported to be underused in UK CF centres, particularly in children. Here, we evaluated the cardiopulmonary exercise testing (CPET) results in children and young people with CF at CF annual review and its possible clinical value. METHOD: An observational study comparing CPET results using a cycle ergometer ramp test (peak oxygen uptake (Vo2peak)) and pulmonary function (forced expiratory volume in 1 s (FEV1)) was performed with body mass index (BMI) used as a disease severity marker...

BACKGROUND: The airways of patients with cystic fibrosis (CF) are highly complex, subject to various environmental conditions as well as a distinct microbiota. Pseudomonas aeruginosa is recognized as one of the most important pulmonary pathogens and the predominant cause of morbidity and mortality in CF. A multifarious interplay between the host, pathogens, microbiota, and the environment shapes the course of the disease. There have been several excellent reviews detailing CF pathology, Pseudomonas and the role of environment in CF but only a few reviews connect these entities with regards to influence on the overall course of the disease...

MicroRNAs (miRNAs), a large family of small and highly conserved non-coding RNAs, regulate gene expression through translational repression or mRNA degradation. Aberrant expression of miRNAs underlies a spectrum of diseases including organ fibrosis. Recent evidence suggests that miRNAs contribute to organ fibrosis through mediating epithelial-mesenchymal transition (EMT). Alleviation of EMT has been proposed as a promising strategy against fibrotic diseases given the key role of EMT in fibrosis. miRNAs impact the expression of specific ligands, receptors, and signaling pathways, thus modulating EMT and consequently influencing fibrosis...

Objective To observe the effect of miR-21 on bleomycin-induced pulmonary fibrosis in rats, and explore the related mechanism. Methods Peripheral blood was collected from idiopathic pulmonary fibrosis (IPF) patients (n=20) and healthy adults (n=20). Fluorescence quantitative real-time PCR was then used to measure miR-21 expression. Forty-five SD rats were randomly divided into control group, miR-21 agomir group and miR-21 antagomir group. Each group included 15 rats. After establishment of pulmonary fibrosis models by intratracheal administration with bleomycin A5, rats in control group, miR-21 agomir group and miR-21 antagomir group were injected at caudal vein with normal saline, miR21 agomir and miR21 antagomir, respectively...

The aims of the present study are to describe the characteristics of rheumatoid arthritis (RA) patients selected for tocilizumab (TCZ), compare the "real-world" effectiveness of TCZ and tumour necrosis factor inhibitors (TNFi) when used as a first biologic and assess the influence of past biologic exposure/concurrent methotrexate (MTX) therapy on post-TCZ treatment outcomes.

Small airway fibrosis is a major pathologic feature of chronic obstructive pulmonary disease (COPD) and is refractory to current treatments. Chronic inflammatory cells accumulate around small airways in COPD and are thought to play a major role in small airway fibrosis. Mice deficient in α/β T-cells have recently been shown to be protected from both experimental airway inflammation and fibrosis. In these models, CD4+Th17 cells and secretion of IL-17A are increased. However, a pathogenic role for IL-17 in specifically mediating fibrosis around airways has not been demonstrated...

Leukotriene B4 as an inflammatory mediator is an important biomarker for different respiratory diseases like asthma, chronic obstructive pulmonary disease or cystic lung fibrosis. Therefore the detection of LTB4 is helpful in the diagnosis of these pulmonary diseases. However, until now its determination in exhaled breath condensates suffers from problems of accuracy. Reasons for that could be improper sample collection and preparation methods of condensates and the lack of consistently assay specificity and reproducibility of the used immunoassay detection system...

The past decade has seen significant advances in understanding of the pathogenesis and progression of lung disease in cystic fibrosis. Pulmonary inflammation, infection and structural lung damage manifest very early in life and is prevalent among preschool children and infants, often in the absence of symptoms or signs. Early childhood represents a pivotal period amenable to intervention strategies that could delay or prevent the onset of lung damage and alter the longer term clinical trajectory for individuals with CF...

Airway remodeling is resultant of a complex multi-cellular response associated with a progressive decline of pulmonary function in patients with chronic airway disease. Here, repeated infections with respiratory viruses are linked with airway remodeling through largely unknown mechanisms. Although acute activation of the Toll like receptor (TLR)3 pathway by extracellular poly(I:C) induces innate signaling through the NFkB transcription factor in human small airway epithelial cells (hSAECs), prolonged (repetitive or tonic) poly(I:C) stimulation produces chronic stress fiber formation, mesenchymal transition and activation of a fibrotic program...

Idiopathic pulmonary fibrosis (IPF), the most common form of chronic interstitial lung disease, is a severe progressive fibrotic disorder of unknown aetiology. The disease has a heterogeneous clinical course, with frequent poor prognosis, similar to malignant disease. Correctly diagnosing IPF has become particularly important in view of the availability of more precise therapeutic indications, thus avoiding steroid treatment and allowing new approaches with novel drugs. To date we have limited information about biomarkers predictive of progressive disease and associated complications...

Idiopathic pulmonary fibrosis (IPF) is a chronic lethal interstitial lung disease with unknown etiology. Recent studies have indicated that heat-shock protein 27 (HSP27) contributes to the pathogenesis of IPF through the regulation of epithelial-mesenchymal transition (EMT). However, the expression and role of HSP27 in fibroblasts during pulmonary fibrogenesis has not been investigated to date, at least to the best of our knowledge. In this study, we examined the expression of HSP27 in fibrotic lung tissue and fibroblasts from bleomycin (BLM)-challenged mice and human lung fibroblasts treated with transforming growth factor-β (TGF-β)...

Mycobacterium abscessus is a pathogenic, rapidly growing mycobacterium responsible for pulmonary and cutaneous infections in immunocompetent patients and in patients with Mendelian disorders, such as cystic fibrosis (CF). Mycobacterium abscessus is known to transition from a smooth (S) morphotype with cell surface-associated glycopeptidolipids (GPL) to a rough (R) morphotype lacking GPL. Herein, we show that M. abscessus S and R variants are able to grow inside macrophages and are present in morphologically distinct phagosomes...
