Filter by:This randomized controlled trial aims to examine the effectiveness of the Acceptance and Commitment Therapy-based Asthma Management Training Program on the health outcomes of asthmatic children with attention deficit hyperactivity disorder (ADHD) and their caregivers over a 12-month post-intervention.
Most children with asthma have concurrent atopy (allergic inflammation), which is associated with an improved response to ICS. However, the absence of an atopic phenotype is associated with a poorer ICS response, leaving clinicians with limited treatment options. The nonatopic asthma phenotype has been characterized as the absence of atopic diseases including allergic rhinitis, eczema, or food allergies, and a negative skin prick test to common aeroallergens. Children with mild asthma treated with ICS over 44 weeks without a positive allergen skin test are 3 times more likely to have an asthma exacerbation when compared with children with positive skin tests. Similarly, adolescents and adults with asthma with low blood eosinophils or low sputum eosinophils have no difference in exacerbation rate response to ICS compared with placebo. Due to poor ICS response in nonatopic children and the known adverse effects of ICS, the development of non-steroid treatments options is needed. Monotherapy with the long-acting muscarinic antagonist, tiotropium, was superior to placebo for treatment failure outcomes in adolescents and adults with low sputum eosinophil levels. Tiotropium is approved in children as an add on therapy to ICS in children ≥ 6 years with asthma. But, this combination of treatment would still expose children with nonatopic asthma to the risks (but potentially without the benefit) of ICS therapy. The objective of this study is to conduct a feasibility pilot safety study of 6-weeks treatment with tiotropium monotherapy vs. ICS in children ages 6 to 11 years old with nonatopic mild persistent asthma.
Chronic cough is a very unpleasant symptom, significantly reduces the patient's quality of life, and bothers the neighborhood. A very common cause or co-factor of chronic cough is extraesophageal reflux (EER). The aim of the project is the precise diagnosis of EER in patients with chronic cough (in patients with a simultaneously diagnosed allergic cause and without it).
There are many symptoms associated with severe asthma, not all of them related to the lung. These are referred to as extra-pulmonary symptoms and their relationship with quality of life is complex. Body reprogramming (BR) is a non-drug intervention originally developed for fibromyalgia patients with the aim of improving health and wellbeing in a personalised way, with evidence-based lifestyle changes. The frequency and severity of multiple symptoms in severe asthma is similar to fibromyalgia and the investigators propose that BR may be a suitable non-drug intervention for severe asthma patients who are about to step up drug treatment. Our study aims are therefore to assess how BR may be suitable for people with severe asthma, and to adapt and optimise the programme for these people. In two phases, severe asthma patients will be recruited via a regional severe asthma clinic at the Royal Devon & Exeter NHS Trust and invited to take part in a short course of BR. In phase one, patients will be asked to attend four weekly researcher-led sessions of BR via video call and be given practice tasks to report on at the subsequent session. Questionnaires will be completed for the first and last session. At the end of BR, patients will also be invited to take part in a focus group. The data collected will inform development of the programme for phase two, which will involve recruitment of severe asthma patient who are about to start biologic drug treatment for their severe asthma
The overall aim in Part 1 is to compare the pharmacokinetic (PK)/pharmacodynamics (PD) relationship in intravenous (IV) versus subcutaneous (SQ) terbutaline sulfate to identify the optimal IV dosing range for use in Part 2. The overall aim in Part 2 is to evaluate the optimal IV dosing of terbutaline sulfate based on PD response and safety data.
Self-management strategies for asthma, including patients engagement and adherence to personalised action plans with advice on recognizing and responding to deterioration in control with effective treatments can improve asthma outcomes and possibly reduce the risk of future exacerbations. However, the real-life evidence is that asthma control remains sub-optimal in the majority of cases, thus increasing the related socio-economic costs worldwide. Because an increased variability of lung function remains a hallmark of poor asthma control and exacerbations, its assessment over time could contribute to the success of self-management plans. Previous studies have shown the potential of Forced Oscillation Technique (FOT) as a tool for monitoring increased variability of airway obstruction and for identifying the onset of acute deterioration of airway function. The aim of this study is to test the hypothesis that a personalised self-management plan including FOT improves asthma control and reduces number of days with increased symptoms compared to conventional asthma treatment.
Allergic diseases, including allergic reactions of respiratory tract and skin, are often triggered by mast cell degranulation mediated by allergen-specific IgE and chronic inflammation of target organs, which are involved in a variety of immune cells and inflammatory factors. Recent studies have shown that intestinal immunity is closely related to immune responses to various diseases. Intestinal microecology influences the occurrence and regression of various diseases by regulating the growth, differentiation and maturation of various immune cells. Probiotics are widely used in children with allergies. This study aims to analyze the correlation between the intestinal microecology of children with rhinitis/asthma, eczema and urticaria and the clinical manifestations of the patients. By observing the influence of probiotics intervention on clinical symptoms and changes in intestinal microecology, the influence of intestinal microecology on children's allergic diseases was clarified. Study protocol: 1) children with definitive diagnosis of allergic rhinitis, asthma，atopic dermatitis and chronic urticaria were enrolled, each with 50 cases. 2) collect manure application of 16s rDNA probe hybridization technique to analyze the fecal flora, and compared with clinical symptoms rating scale and serum sIgE, IgG4 correlation analysis (3) application of probiotic intervention or conventional drug intervention, again in 3 months, 6 months after collecting dung is used to detect the intestinal flora in children with its correlation with clinical symptoms change were observed.
The study aims to evaluate the efficacy, safety and tolerability of FF/UMEC/VI compared with FF/VI via ELLIPTA® inhaler in Chinese participants with inadequately controlled asthma. ELLIPTA is a registered trademark of GlaxoSmithKline group of companies.
To evaluate the awareness/knowledge, clinical practice of atypical asthma among respiratory specialists and primary care practitioners (PCPs) in China.A total of 1166 respiratory specialists and 799 PCPs participated in the questionnaire survey via WeChat. The questionnaire included six major items, divided into physician demographic characteristics, awareness, diagnosis, medication prescription, assessment/education, and proposal.
This mother-infant cohort study aims to determine the geographic differences in the microbial profiles in breast milk from mothers living in Malaysia and China that are potentially important determinants of infant development. It also aims to determine the impact of gut microbiome on infant health (temperament, gastrointestinal symptoms, eczema symptoms, and asthma symptoms).
