Filter by: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.
This study is a double-blind, parallel-group, randomized study of active drug vs placebo in asthma.
One hundred patients were enrolled, based on sensitization and doctor-diagnosed allergy to HDM. Questionnaires were administered to document demographic and clinical characteristics. Serum IgE reactivity toDermatophagoides pteronyssinus (Dp) extract, Der p 1, Der p 2 and Der p 10 was measured by ImmunoCAP.
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.
There are few studies about immunological explorations in COPD. Because of the complications of lung biopsies, analyses are generally made on blood samples instead of lung tissue. No study tried to classify COPD vs Asthma vs ACOS. The investigators wondered if there were differences in biomarkers between these groups. The investigators decided to open a pilot-study among COPD patients followed in Amiens-University Hospital. Each patient will be examined and a blood-test will be performed.
In this study we aimed to assess the clinical and laboratory profile of some Egyptian asthmatic children who are sensitized to house dust mites and determine the association of HDM sensitization and severity of asthma according to recent GINA guidelines.
This study is a 24-week, randomized, parallel group comparative effectiveness study to evaluate the risk of stepping down therapy for patients with well-controlled asthma treated with combination Inhaled corticosteroids (ICS) and Leukotriene receptor antagonist（LTRA).
