OBJECTIVE: Bronchial thermoplasty (BT) is a novel treatment for severe asthma. Its mode of action and ideal target patient group remain poorly defined, though clinical trials provided some evidence on efficacy and safety. This study presents procedural and short-term safety evidence from routine UK clinical practice. METHODS: Patient characteristics and safety outcomes (procedural complications, 30-day readmission and A&E attendance, length of stay) were assessed using two independent data sources, the British Thoracic Society UK Difficult Asthma Registry (DAR) and Hospital Episodes Statistics (HES) database...

BACKGROUND: Cat allergy is of great importance, and its prevalence is increasing worldwide. Cat allergens and house dust mite allergens represent the major indoor allergens; however, they are ubiquitous. Cat sensitization and allergy are known risk factors for rhinitis, bronchial hyperreactivity and asthma. Thus, the diagnosis of sensitization to cats is important for any allergist. METHODS: 70 patients with positive skin prick tests for cats were retrospectively compared regarding their skin prick test results, as well as their specific immunoglobulin E antibody profiles with regard to their responses to the native cat extract, rFel d 1, nFel d 2 and rFel d 4...

The effects of tiotropium, an inhaled long-acting muscarinic antagonist, on lung function were investigated in current smokers and nonsmokers with asthma treated with inhaled corticosteroids (ICSs) and other asthma controllers: inhaled long-acting β2 agonists, leukotriene receptor antagonists, and/or theophylline. We conducted a double-blind, placebo-controlled study of an inhaled single dose of tiotropium in 9 asthmatics currently smoking and 9 asthmatics who have never smoked in a crossover manner. Lung function was measured before and 1, 3, and 24 h after inhalation of 18 μg of tiotropium or a placebo...

OBJECTIVE: Pharmacists play a relevant role in the real-life management of asthma because they are a first-line referral for patients. In fact, the role of pharmacies has been underlined and evidenced also in guidelines. Nonetheless, the true effect of pharmacy-based management of asthma has been assessed in only a few studies. We review the available literature on asthma management in a territorial pharmacy setting. DATA SOURCES: The literature was searched for the keywords pharmacy, bronchial asthma, control, and management...

OBJECTIVE: Eosinophilic chronic rhinosinusitis (ECRS), a subgroup of chronic rhinosinusitis with nasal polyps, is a refractory disease closely associated with bronchial asthma. We recently reported on the efficacy of ultra-fine particle inhaled corticosteroids (ICS) (hydrofluoroalkane-134a-beclomethasone dipropionate: HFA-BDP) exhalation through the nose (ETN) treatment for mild-to-moderate asthmatics with ECRS. However, the effect of HFA-BDP ETN was found to be transient in some cases with severe ECRS and asthma, requiring treatment with higher-dose ICS and long-acting β2-agonists (LABA)...

BACKGROUND: Airway structure changes, termed as airway remodeling, are common in asthma patients due to chronic inflammation, which can be assessed by high-resolution computed tomography (HRCT). Considering the controversial conclusions in the correlation of morphologic abnormalities with clinical feature and outcome, we aimed to further specify and evaluate the structural abnormalities of Chinese asthmatics by HRCT. METHODS: From August 2012 to February 2015, outpatients with asthma were recruited consecutively in the Asthma Center of West China Hospital, Sichuan University...

Hypothiocyanite (OSCN(-)) serves as a potent innate defense system against microbes in the lungs. OSCN(-) is generated by the catalysis of peroxidases using thiocyanate transported via several anion transporters, including pendrin/SLC26A4 and hydrogen peroxide (H2O2) generated by Duox1 and Duox2. We previously demonstrated that expression of pendrin, peroxidases, and Duox1/Duox2 is upregulated in bronchial asthma patients and/or asthma model mice and that these molecules are important in accelerating airway inflammation...

BACKGROUND: IL-23 has been postulated to be a critical mediator contributing to various inflammatory diseases. Dermatophagoides pteronyssinus (Der p) is one of the most common inhalant allergens. However, the role of IL-23 in Der p-induced mouse asthma model is not well understood, particularly with regard to the development of allergic sensitization in the airways. OBJECTIVE: To evaluate roles of IL-23 in Der p-sensitization and asthma development. METHODS: BALB/c mice were repeatedly administered with Der p intra-nasally to develop Der p-allergic sensitization and asthma...

Compelling evidences point out a crucial role for extracellular nucleotides such as adenosine triphosphate (ATP) during inflammatory conditions. Once released into the extracellular space, ATP modulates migration, maturation and function of various inflammatory cells via activating of purinergic receptors of the P2Y- and P2X- family. P2RX4 is an ATP-guided ion channel expressed on structural cells such as alveolar epithelial and smooth muscle cells as well as inflammatory cells including macrophages, dendritic cells (DCs) and T cells...

BACKGROUND: CD48 is a membrane receptor (mCD48) on eosinophils and mast cells and exists in a soluble form (sCD48). CD48 has a pivotal role in murine asthma and in the proinflammatory interactions of mast cells with eosinophils via its ligand CD244. Thus, CD48 might be important in human asthma. METHODS: Therefore, two separate cohorts (IL and UK) comprising mild, moderate, and severe asthma and healthy volunteers were evaluated for blood leukocyte mCD48 expression and sCD48 in serum...

We describe a case of a worker with occupational asthma caused by two separate etiologic agents, resulting from mixed exposures in different work areas. Isocyanates and epoxy resins are established causes of occupational disease, and their role in this case was confirmed by immediate and delayed pulmonary function testing, together with a specific bronchial challenge. A thorough evaluation of exposure to harmful substances in the workplace is essential, together with continued clinical monitoring following cessation of exposure in order to verify clinical improvement...

Leukotrienes (LTs) are inflammatory mediators that play a pivotal role in many diseases like asthma bronchiale, atherosclerosis and in various types of cancer. The key enzyme for generation of LTs is the 5-lipoxygenase (5-LO). Here, we present a novel putative protein isoform of human 5-LO that lacks exon 4, termed 5-LOΔ4, identified in cells of lymphoid origin, namely the Burkitt lymphoma cell lines Raji and BL41 as well as primary B and T cells. Deletion of exon 4 does not shift the reading frame and therefore the mRNA is not subjected to non-mediated mRNA decay (NMD)...

The pathogenesis of asthma includes a complex interplay between airway inflammation, hyperresponsiveness, and remodeling. Current evidence suggests that airway structural cells - including bronchial smooth muscle cells, myofibroblasts, fibroblasts, and epithelial cells -mediate all three aspects of asthma pathogenesis. While studies show a connection between airway remodeling and changes in bronchomotor tone, the relationship between the two remains unclear. Transforming growth factor beta 1 (TGF-ß1), a growth factor elevated in the airway of patients with asthma, plays a role in airway remodeling and the shortening of various airway structural cells...

We herein describe the first known case of diffuse alveolar hemorrhage (DAH) associated with the administration of Makyo-kanseki-to, a Chinese herbal drug. A 64-year-old man with bronchial asthma presented with persistent cough. Makyo-kanseki-to was prescribed as an adjunctive treatment for bronchial asthma. Immediately after drug ingestion, the patient expectorated bloody sputum. DAH was diagnosed based on the presence of bilateral ground-glass opacity which was identified on chest computed tomography and bloody bronchoalveolar lavage fluid...
