Filter by:The primary objective of the study is to show that ventilation heterogeneity identified by hyperpolarized helium-3 lung MRI is prevalent children with poorly controlled asthma despite guidelines-based treatment with ICS. The secondary objective is to demonstrate whether or not eight weeks of treatment with extra-fine particle ICS (HFA-BDP) improves ventilation heterogeneity compared to treatment with a coarse particle ICS (fluticasone HFA or dry powder).
Little guidance is given to physicians caring for obese adolescents with asthma, however, findings suggest that interventions designed to achieve asthma control in these patients are necessary. Because of the psychosocial factors often associated with obesity and asthma (e.g., low self-esteem, depression, and low quality of life) successful interventions should incorporate a patient-centered approach. The proposed study design is a clinic-based, randomized controlled trial (RCT) in teens with a history of asthma and who are overweight or obese.
Bronchial asthma is a common chronic respiratory disease. Patients usually manifest variable symptoms (such as short of breath, chest tightness, cough, etc.) and variable airflow limitation and often associated with airway hyper-responsiveness and airway inflammation. About 1-18% of the global population suffered from the disease, causing huge economic burden for patients and countries. Airway reactivity measurement is an important way of diagnosis of asthma. Methacholine (Mch) bronchial provocation test(BPT) is the "gold standard" for the determination of airway reactivity, and other measuring methods(like adenosine monophosphate(AMP)-BPT, leukotriene D4(LTD4)-BPT, Astograph-BPT, etc.) were also brought into hot research fields. The investigators' purposes were to compare different kinds of methodologies(Mch,AMP,LTD4-BPT, Astograph-BPT) assessing airway responsiveness and to investigate treatment efficacy of budesonide /formoterol in asthmatics.
To study whether the immune response as directed by regulatory T cells is different between obese asthmatics, normal weight asthmatics and healthy controls.
Primary Objective: To evaluate the effect of dupilumab, compared to placebo, on airway inflammation in participants with persistent asthma. Secondary Objective: To assess the safety, tolerability, and immunogenicity of dupilumab compared to placebo.
The purpose of the trial was to evaluate the efficacy and safety of two different doses of QVM149 (QVM149 150/50/80 μg and QVM149 150/50/160 μg via Concept1) over two respective QMF149 doses (QMF149 150/160 μg and QMF149 150/320) μg via Concept1 in poorly controlled asthmatics as determined by pulmonary function testing and effects on asthma control.
Asthma is a disease that represents a public health problem worldwide, there are several barriers, especially in pediatric patients with this disease, them, prevent the adequate control of their condition, in addition every day there are new processing aids for this entity; within these novel research we founded the relationship between decreased vitamin D serum levels and his role in the regulating of the immune response, also this relationship in the pathophysiology of this disease and responses in the event of infectious diseases of the respiratory tract which can exacerbate symptoms in pediatric patients. We have been some of clinical trials with the aim of improving serum levels of vitamin D in asthmatic patients, however, these studies have different sources of bias and thus far there is no solid evidence that favors or denies the relationship between asthma and vitamin D, this paper aims to help generate this evidence to improve clinical management of these patients and their lung function and increase the free time crisis. In this trial two study groups which are divided for each of the interventions described below: Group low supplementation dose: 1 tablet of 400 IU was administered every 24 hours via oral, regardless of time or if it is before or after food, preferably in the morning to improve adherence to treatment, will be completed one year of treatment without suspension. Group high supplementation dose: 1 tablet of 1600 IU should be administered every 24 hours via oral, regardless of time or if it is before or after food, preferably in the morning to improve adherence to treatment, will be completed one year of treatment without suspension thereof.
Correct methods and compliance of intranasal corticosteroid (INCS) is very important for the treatment of allergic rhinitis (AR). The animated cartoon-aided teaching of INCS administration was created to decrease workload of health care professionals. The aim of this study is to compare the achievement of the children with AR in using INCS between the group which were instructed by animated cartoon-aided teaching or oral presentation without demonstration.
Primary aim: Evaluating the effect of Asthmatuner on patients´ self-reported asthma control test (ACT/C-ACT)compared with conventional asthma management. Secondary aim: Evaluating patients´ health-related quality of life (HR-QoL) medical adherence by using Asthmatuner compared with conventional management. Total sample size: Stratified study population consisting of 43 females and males with diagnosed asthma at the age of at least 6 years pediatric specialist care and 43 females/males in primary care. Study design: This is a multi-centre, blinded, randomized controlled, cross-over trial over to at least 16 weeks. Subjects: Two stratified groups of participants with uncontrolled asthma will be recruited; (1) children and adolescents from Astrid Lindgren's Children's Hospital, Karolinska University Hospital, and (2) adolescents and adults from the primary health care sector in Stockholm, Sweden. The asthma control test (ACT/C-ACT) will be applied for evaluation of asthma control, a score less than 20 will be required for inclusion. Intervention: Asthmatuner is an app supporting self-management evaluating symptoms and lung function with external spirometry. The app gathers the information to define patients´ asthma control. Subsequently, Asthmatuner provides the patient with a treatment recommendation based on the individual treatment plan. Procedures: Participants are randomized (1:1) into the one of two-arms of asthma self-management with Asthmatuner - conventional or conventional - Asthmatuner. Questionnaires will collect information about asthma control, HR-QoL, Medicine adherence report scale (MARS) and history of medical health concerning health care utilization and personal costs and income. Analysis: The study hypothesis will be tested by examining difference in patients´ change in asthma control (ACT/C-ACT) and HR-QoL (PAQLQ/Mini-AQLQ). Results will be summarized at each management period as mean scores and analysed by paired t-tests.
This trial is a randomized, double-blind, placebo controlled trial designed to test whether two years treatment of preschool children aged 2-3 years of age at high risk for asthma with omalizumab (anti-IgE) for two years will prevent the progression to childhood asthma, as reflected by a reduction in the prevalence of active asthma in the Final 12 months during 2 year observation period off study drug.
