REVIEW
Valérie Cochen De Cock
PURPOSE OF REVIEW: The purpose of this review was to explore the different sleep disorders associated with MSA, their mechanisms, and their treatments. RECENT FINDINGS: Stridor is a red flag for the diagnosis of MSA. Recent findings show that its presence in early stage of the disease is associated with a reduction in life expectancy. Its management should be fast and adapted. Its treatment with continuous positive airway pressure or tracheostomy is efficacious...

In children with cystic fibrosis (CF) the associations between oropharyngeal swabs (OPS) for detection of Pseudomonas and lung disease has not been evaluated.OPS and bronchoalveolar lavage (BAL) samples were obtained annually in children with CF from 2005 to 2017. OPS test characteristics were calculated using BAL as gold standard. Results were related to lung inflammation (BAL neutrophil elastase, interleukin-8), structural lung disease (chest CT PRAGMA-CF scores), respiratory exacerbations, and future detection of Pseudomonas on BAL...

Patients with chronic airway diseases tend to become "accustomed" to their impairments and fail to recognize the significance of their symptoms. We suggest that a metabolomic approach could become a diagnostic/monitoring solution in clinical trials or in a typical doctor's office.

BACKGROUND: Thirdhand smoke (THS) represents the accumulation of secondhand smoke on indoor surfaces and in dust, which, over time, can become more toxic than secondhand smoke. Although it is well known that children of smokers are at increased risk for developing asthma and for exacerbation of that disease if they already have it, how exposure to THS may influence the development or exacerbation of asthma remains unknown. OBJECTIVE: We investigated whether epicutaneous exposure to an important component of THS, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), can influence asthma pathology in a model elicited in mice by repeated intranasal challenge with cockroach antigen (CRA)...

BACKGROUND: Immunoglobulin(Ig)E-associated allergies result from misguided immune responses against innocuous antigens. CD4+ T lymphocytes are critical for initiating and perpetuating that process, yet the crucial factors determining whether an individual becomes sensitized towards a given allergen remain largely unknown. OBJECTIVE: To determine the key factors for sensitization and allergy towards a given allergen. METHODS: We here created a novel human T cell receptor(TCR) and human leucocyte antigen (HLA)-DR1 (TCR-DR1) transgenic mouse model of asthma, based on the human-relevant major mugwort (Artemisia vulgaris) pollen allergen Art v 1 to examine the critical factors for sensitization and allergy upon natural allergen exposure via the airways in the absence of systemic priming and adjuvants...

The aim of the present investigation was to evaluate the influence of liposome formulation on the ability of vesicles to penetrate a pathological mucus model obtained from COPD affected patients in order to assess the potential of such vesicles for the treatment of chronic respiratory diseases by inhalation. Therefore, Small Unilamellar Liposomes (PLAIN-LIPOSOMEs), Pluronic® F127-surface modified liposomes (PF-LIPOSOMEs) and PEG 2000PE-surface modified liposomes (PEG-LIPOSOMEs) were prepared using the micelle-to-vesicle transition (MVT) method and beclomethasone dipropionate (BDP) as model drug...

Electronic nose (eNose) and nuclear magnetic resonance (NMR)-based metabolomics seem to be able to identify metabolic and inflammatory profiles in patients with chronic obstructive diseases. The hypothesis arises from three recent studies using two different methods in patients with asthma and chronic obstructive pulmonary diseases (COPD), opening promising diagnostic perspectives. The possibility that the use of eNose and NMR-based metabolomics might provide clinical/inflammatory characteristics is intriguing...

The administration of Everolimus (EVE), a mTOR inhibitor used in transplantation and cancer, is often associated with adverse effects including pulmonary fibrosis. Although the underlying mechanism is not fully clarified, this condition could be in part caused by epithelial to mesenchymal transition (EMT) of airway cells. To improve our knowledge, primary bronchial epithelial cells (BE63/3) were treated with EVE (5 and 100 nM) for 24 h. EMT markers (α-SMA, vimentin, fibronectin) were measured by RT-PCR. Transepithelial resistance was measured by Millicell-ERS ohmmeter...

Detrimental effects of air pollution with fine dust (particulate matter ≤2.5 μm in aerodynamic diameter, or PM2.5 ) on the systemic circulation and the left heart have been studied intensely during the past decade. In comparison, knowledge regarding the effects of exposure to air pollution with PM2.5 on the pulmonary vasculature and the right heart lags far behind. A report on severe lung disease and right heart failure in coal miners was published nearly 170 years ago. However, today, we still do not have a clear picture of how the effect of air pollution on the pulmonary circulation or the right heart should be viewed from a clinical, mechanistic biological, therapeutic, or economic angle...

RATIONALE: An unknown number of post-9/11 military deployers to Iraq and Afghanistan have returned with respiratory symptoms and may be at risk for deployment-related distal lung disease, detected only on surgical lung biopsy. We hypothesized that cardiopulmonary exercise testing and lung clearance index scores would differ significantly between deployers with and without biopsy-proven deployment-related distal lung disease. OBJECTIVES: To assess if there are differences in cardiopulmonary exercise testing and lung clearance index scores between deployers with and without biopsy-proven deployment-related distal lung disease...

About 50% of patients with asthma exhibit chronic airway inflammation driven by the type 2 cytokines interleukin (IL)-4, IL-5, and IL-13. These patients with type 2-high asthma experience more allergic symptoms, greater airway hyperresponsiveness, and more severe mucus obstruction than patients with type 2-low asthma. Mouse models of asthma have shown that much of the airway dysfunction in these models can be generated by IL-13 stimulation of the airway epithelium alone. Both in vivo mouse model studies and in vitro studies of human mucociliary airway epithelial cultures have shown that IL-13 induces cellular remodeling of the airway epithelium through proliferation-independent transdifferentiation processes...

B cell interaction with follicular helper T cells and their subsequent differentiation into high-affinity antibody producing cells normally takes place in secondary lymphoid organs. The costimulator ICOS plays a key role in this process and is therefore considered as an attractive target to modulate exaggerated B cell responses in autoimmune or allergic diseases. Inflamed tissues were recently recognized as additional sites of active T cell/B cell interaction. To analyze whether ICOS costimulation is also important there, we employed a mouse airway inflammation model which allows to directly compare immune reactions in the lung-draining lymph node and the lung tissue and also to assess the relative importance of dendritic cells versus B cells as antigen-presenting cells...

PURPOSE: Severe asthma and asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) are difficult to control and are often associated with poor clinical outcomes. However, much is not understood regarding the diagnosis and treatment of severe asthma and ACOS. To evaluate the current perceptions of severe asthma and COPD among asthma and COPD specialists, we designed an e-mail and internet-based questionnaire survey. METHODS: Subjects were selected based on clinical specialty from among the members of the Korean Academy of Asthma, Allergy and Clinical Immunology and the Korean Academy of Tuberculosis and Respiratory Diseases...

PURPOSE: Asthma is a chronic inflammatory airway disease characterized by airway hyperresponsiveness (AHR), inflammation, and remodeling. There is emerging interest in the involvement of the transient receptor potential vanilloid 1 (TRPV1) channel in the pathophysiology of asthma. This study examined whether TRPV1 antagonism alleviates asthma features in a murine model of chronic asthma. METHODS: BALB/c mice were sensitized to and challenged by ovalbumin to develop chronic asthma...

The development of chronic obstructive pulmonary disease (COPD) pathogenesis remains unclear, but emerging evidence supports a crucial role for inducible bronchus-associated lymphoid tissue (iBALT) in disease progression. Mechanisms underlying iBALT generation, particularly during chronic CS exposure, remain to be defined. Oxysterol metabolism of cholesterol is crucial to immune cell localization in secondary lymphoid tissue. Here, we demonstrate that oxysterols also critically regulate iBALT generation and the immune pathogenesis of COPD In both COPD patients and cigarette smoke (CS)-exposed mice, we identified significantly upregulated CH25H and CYP7B1 expression in airway epithelial cells, regulating CS-induced B-cell migration and iBALT formation...

Alveolar epithelial cells are critical to the pathogenesis of pulmonary inflammation and fibrosis, which are associated with overexpression of type 2 cytokine IL-13. IL-13 is known to induce the production of profibrotic (e.g., periostin) and pro-inflammatory (e.g., eotaxin-3) mediators in human airway epithelial cells, but it remains unclear if human primary alveolar epithelial cells increase periostin and eotaxin expression following IL-13 stimulation. The goals of this study are to determine if alveolar epithelial cells increase periostin and eotaxin expression upon IL-13 stimulation, and if alveolar and airway epithelial cells from the same subjects have similar responses to IL-13...

The diaphragm is the main inspiratory muscle and is required to be highly active throughout the lifespan. The diaphragm muscle must be able to produce and sustain various behaviors that range from ventilatory to non-ventilatory such as those required for airway maintenance and clearance. Throughout the lifespan various circumstances and conditions may affect the ability of the diaphragm muscle to generate requisite forces and in turn the diaphragm muscle may undergo significant weakness and dysfunction. For example, hypoxic stress, critical illness, cancer cachexia, chronic obstructive pulmonary disorder (COPD), and age-related sarcopenia all represent conditions in which significant diaphragm muscle dysfunction exits...

PURPOSE: Cumulative evidence supports the clear relationship of obstructive sleep apnea (OSA) with cardiovascular disease (CVD). And, adherence to continuous positive airway pressure (CPAP) treatment alleviates the risk of CVD in subjects with OSA. Vascular endothelial growth factor (VEGF), a potent angiogenic cytokine regulated by hypoxia-inducible factor, stimulates the progression of CVD. Thus, whether treatment with CPAP can actually decrease VEGF in patients with OSA remains inconclusive...
