The characteristics of Mycoplasma pneumonia (M. pneumoniae)-associated bronchiolitis obliterans (BO) are not well known. We retrospectively reviewed 17 patients with M. pneumoniae-associated BO. All patients had M. pneumoniae-associated acute bronchiolitis prior to the development of BO. In the acute bronchiolitis stage, all patients had fever and cough; six patients also had wheezing and dyspnoea. BO was diagnosed approximately 1.5-8 months later based on clinical manifestations and chest high-resolution computed tomography (HRCT) findings...

Milonine is an alkaloid of Cissampelos sympodialis Eichl. (Menispermaceae), a plant used in the northeast of Brazil to treat allergies such as asthma, rhinitis, and other conditions. Previously, several alkaloids were isolated from its roots and leaves with pharmacological properties in asthma and acute inflammation models. Therefore, the aim of this study was to evaluate the milonine effect on mast cells degranulation in vivo and in vitro. Swiss mice (n = 8) were used in models of paw edema induced by carrageenan, compound 48/80, or histamine...

This protocol describes noninvasive sampling of undisturbed upper airway mucosal lining fluid. It also details the extraction procedure used prior to the analysis of immune mediators in fluid eluates for the study of the airway topical immune signature, without the need for stimulation procedures (often used by other techniques). The mucosal lining fluid is sampled on a strip of filter paper placed at the anterior part of the inferior turbinate and left for 2 min of absorption. Analytes are eluted from the filter papers, and the extracted protein-based eluates are analyzed by an electrochemiluminescence-based immunoassay, allowing for the high-sensitivity quantification of low- and high-level analytes in the same sample...

Evidence is emerging on the use of long-acting muscarinic antagonists (LAMAs) in the management of asthma. Tiotropium bromide (Spiriva(®) Respimat(®)) is the only LAMA approved in children and adolescents. As the use of tiotropium becomes more common in clinical practice, it is necessary to review the existing data to identify patients who may benefit from the addition of this medication to their daily asthma regimen. This review discusses recent evidence on the safety and efficacy of tiotropium bromide in the management of asthma in children and adolescents...

BACKGROUND: Near-fatal asthma attacks are life threatening events that often require mechanical ventilation. Extracorporeal carbon dioxide removal (ECCO2R) is, beside extracorporeal membrane oxygenation (ECMO), a well-established rescue option whenever ventilation gets to its limits. But there seems to be very rare experience with those techniques in avoiding mechanical ventilation in severe asthma attacks. CASE PRESENTATION: A 67-year-old man with a near-fatal asthma attack deteriorated under non-invasive ventilation conditions...

In asthma, bronchoconstriction causes topographically heterogeneous airway narrowing, as measured by 3-dimensional ventilation imaging. Computation modelling suggests that peripheral airway dysfunction is a potential determinant of acute airway narrowing measured by imaging. We hypothesised that the development of low ventilation regions measured topographically by 3-dimensional imaging after bronchoconstriction is predicted by peripheral airway function. Fourteen (14) asthmatic subjects underwent ventilation Single Photon Emission Computed Tomography/CT (VSPECT/CT) before and after methacholine challenge...

BackgroundPoor aerobic fitness is associated with worsening of asthma symptoms, and fitness training may improve asthma control. The mechanism linking fitness with asthma is not known. We hypothesized that repeated bouts of exercise would lead to a downregulation of glucocorticoid receptor (GR) expression on circulating leukocytes, reflecting a reduced responsiveness to stress.MethodsIn a prospective exercise training intervention of healthy and asthmatic adolescents, GR expression in leukocytes was measured using flow cytometry in response to an acute exercise challenge before and after the exercise training intervention...

BACKGROUND: Soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) is a cell-surface receptor presented on neutrophils, macrophages and monocytes. Elevated sTREM-1 levels are a marker of acute microbial infections, and have also been reported in chronic lung diseases. IL-6 and IL-13 are effective markers in distinguishing these diseases. IL-6 has been shown to play an important role in chronic obstructive pulmonary disease (COPD), while IL-13 is described as one of the key mediators of allergic asthma...

Bronchial asthma is one of the most common chronic inflammatory diseases of the airways. In the pathogenesis of this disease, the interplay among the genes, intrinsic, and extrinsic factors are crucial. Various combinations of the involved factors determine and modify the final clinical phenotype/endotype of asthma. Oxidative stress results from an imbalance between the production of reactive oxygen species and reactive nitrogen species and the capacity of antioxidant defense mechanisms. It was shown that oxidative damage of biomolecules is strongly involved in the asthmatic inflammation...

Chronic asthma patients experience difficulties even years after the inciting allergen. Although studies in small animal asthma models have enormously advanced progress in uncovering the mechanisms of inception and development of the disease, little is known about the processes involved in the persistence of asthma symptoms in the absence of allergen exposure. Long term asthma mouse models have so far been scarce or not been able to reproduce the findings in patients. Here we used a common ovalbumin induced acute allergic airway inflammation mouse model to study lung function and remodeling after a four months recovery period...

Omics approaches are high-throughput unbiased technologies that provide snapshots of various aspects of biological systems and include: 1) genomics, the measure of DNA variation; 2) transcriptomics, the measure of RNA expression; 3) epigenomics, the measure of DNA alterations not involving sequence variation that influence RNA expression; 4) proteomics, the measure of protein expression or its chemical modifications; and 5) metabolomics, the measure of metabolite levels. Our understanding of pulmonary diseases has increased as a result of applying these omics approaches to characterize patients, uncover mechanisms underlying drug responsiveness, and identify effects of environmental exposures and interventions...

Fine particulate matter (PM2.5) has been linked to exacerbation of allergic airway inflammation in mice. However, the mechanism underlying exposure to PM2.5 and subsequent and adverse effects remains to be fully elucidated. Therefore, the present study aimed to investigate the effects of PM2.5 by different levels on airway inflammation in mouse models of in allergic and steroid‑resistant asthma. BALB/c mice were nasally instilled with PBS (control) or 10, 31.6 or 100 µg PM2.5, and randomly assigned into nine groups...
