Background Asthma control falls short of current goals of asthma management guidelines. Non-invasive monitoring of airway inflammation may help to improve the level of asthma control in children. Aim 1) To identify a set of exhaled volatile organic compounds (VOCs) that is most predictive for an asthma exacerbation in children. 2) To determine the chemical background of predictive VOCs. Methods In an one-year prospective observational study, 96 asthmatic children were studied . At clinical visits with an interval of 2 months, asthma control, fractional exhaled nitric oxide, lung function (FEV1, FEV1/VC) and VOCs in exhaled breath were determined by means of gas chromatography time-of-flight mass spectrometry...

Aspergillus fumigatus sensitization and culture in asthma are associated with disease severity and lung function impairment, but their relationship with airway inflammation is poorly understood. We investigated the profile of 24 sputum inflammatory mediators in A. fumigatus culture-positive or-negative moderate-to-severe asthmatics. Fifty-two subjects were recruited from a single center. A. fumigatus was cultured from 19 asthmatics. Asthma control, symptom score, lung function, and sputum cell count were not significantly different between the asthmatics with and without a positive A...

PURPOSE: Extrafine-particle inhaled corticosteroids (ICS) have greater small airway deposition than standard fine-particle ICS. We sought to compare asthma-related outcomes after patients initiated extrafine-particle ciclesonide or fine-particle ICS (fluticasone propionate or non-extrafine beclomethasone). METHODS: This historical, matched cohort study included patients aged 12-60 years prescribed their first ICS as ciclesonide or fine-particle ICS. The 2 cohorts were matched 1:1 for key demographic and clinical characteristics over the baseline year...

Poor compliance with conventional asthma medications remains a major problem in achieving asthma control. Nigella sativa oil (NSO) is used traditionally for many inflammatory conditions such as asthma. We aimed to investigate the benefits of NSO supplementation on clinical and inflammatory parameters of asthma. NSO capsules 500 mg twice daily for 4 weeks were used as a supplementary treatment in a randomized, double-blind, placebo-controlled trial in asthmatics (clinicaltrials.gov: NCT02407262). The primary outcome was Asthma Control Test score...

BACKGROUND: Previous literature documents associations between low socioeconomic status (SES) and poor health outcomes, including asthma. However, this literature has largely focused on the effects of current family circumstances. OBJECTIVE: To test an intergenerational hypothesis, that the childhood SES that parents experience will be associated with asthma outcomes in their children, independent of effects of current family SES. Secondly, to test whether this association is in part due to difficulties in current parent-child relationships...

OBJECTIVE: To determine the impact of self-reported maternal depression/anxiety on asthma control during pregnancy. METHOD: Pregnant women with a doctor diagnosis of asthma (n = 189) were prospectively recruited at their antenatal booking visit and the presence of maternal depression and anxiety was identified using self-report and routine questionnaire assessments. Data on exacerbations and asthma control were collected during gestation. Asthma control was assessed using the Juniper asthma control questionnaire and women were classified as having recurrent uncontrolled asthma if their ACQ score was > 1...

Dysfunctional breathing (DB) is a common comorbidity in adults with incomplete asthma control. The few available large-scale, randomized studies suggest efficacy of physiotherapy on symptom burden. In this article we discuss the current evidence including the need for systematic description of physiotherapeutic interventions. We also describe how access to physiotherapy service for DB (with or without asthma) is highly heterogeneous in Denmark, and that there is a need for increasing awareness of physiotherapy implementation for and research in DB (with or without concomitant asthma)...

BACKGROUND: In many patients with mild asthma, the low frequency of symptoms and the episodic nature of exacerbations make adherence to regular maintenance treatment difficult. This often leads to over-reliance on short-acting β2-agonist (SABA) reliever medication and under-treatment of the underlying inflammation, with poor control of asthma symptoms and increased risk of exacerbations. The use of budesonide/formoterol 'as needed' in response to symptoms may represent an alternative treatment option for patients with mild asthma...

Children with asthma have a high prevalence of anxiety disorders, however, very little is known about the mechanisms that confer vulnerability for anxiety in this population. This study investigated whether children with asthma and anxiety disorders display attentional biases towards threatening stimuli, similar to what has been seen in children with anxiety disorders more generally. We also examined the relationships between attentional biases and anxiety symptomatology and asthma control for children with asthma...

BACKGROUND: Inhaled corticosteroid (ICS) titration in asthma is primarily based on symptoms and pulmonary function. ICSs may not be increased on this basis despite residual airway inflammation. OBJECTIVE: To compare the dose-response relationships of ICSs on measures of pulmonary function, symptoms, and inflammation in patients with persistent asthma. METHODS: We performed a pooled post hoc analysis of 121 patients with mild to moderate asthma from 4 randomized clinical trials that incorporated an ICS dose ramp...

BACKGROUND: MicroRNAs are small yet versatile gene tuners that regulate a variety of cellular processes, including cell growth and proliferation. Here we report that miR-23b inhibited airway smooth muscle cells (ASMCs) proliferation through directly targeting of Smad3. METHODS: We obtained ASMCs by laser capture microdissection of normal and asthmatic mice lung tissues. Mice ASMCs were cultured and induced by TGF-β1. The implication between TGF-β1 and miR-23b in ASMCs were detected by RT-PCR...

Poor asthma control is associated with increased airway neutrophils. Leukotriene B4 (LTB4) is a potent neutrophil chemoattractant. We examined the levels of LTB4 levels in the sputum of asthma patients and the relationship with disease severity. 47 asthma patients (categorised according to Global Initiative for Asthma treatment stage) and 12 healthy controls provided sputum samples that were processed first with PBS to obtain supernatants and secondly with dithiothreitol (DTT) to obtain supernatants. LTB4 levels were determined by ELISA...

OBJECTIVE: The use of omalizumab, a humanized monoclonal antibody able to binding Ig-E, is currently authorized only for treatment of severe bronchial asthma. The use of omalizumab in other Ig-E related diseases is off-label, although some studies have provided promising results about it. The aim of this study was to evaluate if therapy with omalizumab in patients affected by asthma and allergic rhinitis has an impact also on allergic rhinitis-related symptoms. PATIENTS AND METHODS: A longitudinal study was conducted on 11 patients affected by severe asthma and a periodic allergic rhinitis...
