View clinical trials related to Bronchial Asthma.
Filter by:Bronchial asthma is a common respiratory disease characterized by chronic airway inflammation, which have been affecting about 1-18% of the population in the world, causing tremendous economic burden for the patients and countries. Generally, asthma is a heterogeneous disease, and it could be classified into many types on the basis of symptoms, that is, typical asthma, cough variant asthma, and chest tightness variant asthma etc. Typical asthma (TA) is defined according to the history of repeated respiratory symptoms such as wheeze, shortness of breath, chest tightness, and cough, usually with reversible airflow limitation, airway hyper-responsiveness, and airway remodeling. Cough variant asthma (CVA) is characterized by the single manifestation, recurrent cough, which could be improved after the use of bronchodilators. However, according to different guidelines, it is still controversial on the treatment of CVA and TA. The guidelines of Global Initiative for Asthma(GINA) in 2014 put forward the treatment of TA patients, but did not list the treatment specific to CVA. The guideline of ACCP（American College of Chest Physicians） and cough guidelines of China are proposed to treat the CVA effectively with bronchial diastolic drug. Inhaled corticosteroids (ICS) and leukotriene receptor antagonists are effective for the treatment of CVA. Currently, more and more studies supported that application of ICS combined with bronchial dilation agents is more beneficial to CVA patients. Budesonide/formoterol is a compound of ICS and long-acting beta2-agonist(LABA), which can not only be used as a maintenance medication, but also be used as a relief medication, namely, budesonide/formoterol treatment regimen for SMART (Symbicort as both maintenance and reliever therapy). Most studies show that SMART treatment can be used in the treatment of TA patients. But the study on whether budesonide/formoterol can be used to treat CVA is still little. To provide basis for clinical medication guidance for patients with CVA and TA, this study will enroll 30 patients with TA or CVA , who will be required to adopt the SMART regimen in the following 6 months.The symptom score, airway inflammation, pulmonary function and airway reactivity changes, will be measured every mouth. After the study finished, the investigators will compare the difference between the two groups.
The aim of this trial is to study the effect of a polyherbal capsule containing four herbs: Inula racemosa, Ocimum sanctum, Terminalia Belerica and Piperum longum in the treatment of bronchial asthma.
Severe asthma is a heterogeneous disease characterized by the need for treatment with high doses of inhaled corticosteroids. It affects 5%-10% of asthmatic patients, although it accounts for a significant percentage of the consumption of health care resources. Severe asthma comprises various clinical and pathophysiological phenotypes. In this current study, we aimed to clinical characteristics and cytokes profile in severe asthma patients.
Current diagnostic tools used in pulmonary disease often do not meet the challenges set by the respective pathophysiology. The investigators therefore aimed to evaluate novel or not widely used diagnostic approaches for the detection and therapeutic monitoring of patients with various pulmonary diseases.
The purpose of this study is to demonstrate the pharmacodynamic bioequivalence of the test product to the reference product, using bronchoprovocation (methacholine challenge testing) in adult patients with stable mild asthma.
The purpose of this study is to determine mean or median of fractional exhaled nitric oxide (FeNO) in Thai atopic asthmatic children that divided into subgroups due to asthma exacerbation according to the global initiative for asthma guideline.
Many studies have investigated the efficacy and safety of Intravenous magnesium sulfate and inhaled steroids in addition to the standard treatment for patients with severe asthma attacks. In this 2x2 factorial design blinded randomized study, no interaction of hypothesized treatments is expected.Investigators hypothesize that two doses of intravenous magnesium sulfate,a high dose followed by a (lower) standard dose, will shorten the time to medical readiness for discharge compared to a single standard dose followed by placebo.The second hypothesis is that nebulized inhaled budesonide will be superior to placebo.
Humidified High Flow Nasal Cannula (HHFNC) is a new modality of respiratory support for children with respiratory failure. Despite its extensive use in pediatric and adult population, the exact mechanism of work of HHFNC is not fully explained.The objective of the investigators' research project is to determine the relationship between the amount of airway pressure that can be delivered at specific flow levels of HHFNC. This information will allow the investigators to use HHFNC in a much more informed and safe manner.
Approximately 5% of asthma patients suffer from severe asthma that is characterized by frequent asthma exacerbations resulting in significant morbidity and excessive utilisation of health care resources. Therefore, there is a strong need for improved therapeutic strategies for these patients. Insight in the pathogenesis and molecular pathways active in severe asthma is crucial to reach this goal. Bronchial Thermoplasty (BT) is a novel, innovative device-based treatment of severe asthma that is based on local, radiofrequent energy delivery in larger airways during bronchoscopy. Hypothesis: BT-induced clinical improvement in severe asthma is a consequence of reduction in airway smooth muscle (ASM) mass and (contractile/immunomodulatory) function, inflammation, neural innervation and/or vascular integrity resulting in altered airway remodelling. BT target identification and severe asthma phenotyping are critical for improved patient selection for BT and fundamental to discover novel, specific signalling pathways active in severe asthma.
The aim of the study is to compare the effect of asthma care by clinical pharmacist intervention versus routine care on asthma control.
