Filter by: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.
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.
Bronchial asthma is an chronic airway disease with bronchial hypersensitivity due to inflammation and bronchial muscle contraction. It can cause recurrent dyspnea, cough, wheezing and severe life-threatening attack and lower quality of life. In addition, it make large amount of socioeconomic loss as about 3.7 billion US dollars.
Non-invasive inert gas rebreathing (IGR) based on the Fick Principle showed promising results in the determination of pulmonary blood flow (PBF). The volume of the rebreathing bag (Vbag) is proposed by the system, however, elderly patients or those suffering from high grade pulmonary diseases might be unable to entirely rebreathe this volume and therefore fail to completely mix the test gases. The aim of our study is to evaluate the effect of adapting Vbag on the reproducibility of IGR measurements in patients with obstruction (group A), restriction (group B) and pulmonary healthy controls (group C).
The purpose of the investigation is to confirm the safety of patients receiving Symbicort Turbuhaler as maintenance and reliever therapy ( Symbicort SMART) under the post-marketing actual use.
- To search the effects of montelukast on the airway inflammation including FEV1%, FEV1%/FVC, the provocholine® (methacoline chloride powder for inhalation) challenge tests, the leukotriene levels in the exhaled breath condensate in asthmatic children with and without food allergy aged 6-18 years old. - To define the patient groups with good response to montelukast and to define the parameters which predict the good response.
The aim of the trial is to investigate asthma control with 160 to 640 μg ciclesonide/day. Asthma control will be assessed by the Asthma Control Questionnaire (ACQ).
