Filter by:Five percent of children in the UK are prescribed steroid inhalers to control asthma symptoms but there is no test to determine whether the dose of steroids is correct. Too much steroid treatment has potential side effects and too little may lead to asthma attacks. Exhaled nitric oxide (ENO) is a gas present in everyone's breath and may be a useful "meter" for asthma control. In children, ENO can be measured easily and quickly, the results are available immediately to the doctor or nurse and for these reasons ENO is an attractive clinical test. Pioneering studies have used ENO to help clinicians treat asthmatic adults and children and the results are promising. Breathing tests improved among those where asthma treatment was guided by ENO and asthma symptoms were slightly less frequent. These studies all used a single ENO value to increase or reduce treatment and study authors have suggested there should be a range of ENO values where treatment is neither increased nor reduced; what is not known is what these ENO values may be. Elevated NO is associated with a number of factors other than asthma, including allergy and pollen exposure. What is not known is how factors other than asthma affect ENO measurements over time. The proposed study will answer two important questions: What values of ENO indicate that steroid treatment should be increased or reduced? And how much does ENO rise and fall normally? The investigators will recruit 200 asthmatic and non-asthmatic children. The investigators will measure ENO on six occasions over a 12-month period. The investigators will measure factors that may affect ENO other than asthma. For the asthmatic children, the investigators will also assess asthma control. The investigators' methodology is based on several years experience with ENO. The investigators' results will allow ENO to be used to monitor asthma.
The purpose of this study is to compare the efficacy and safety of nebule procaterol with nebule salbutamol in the treatment of moderate acute asthma.
1. The primary objective of this study is: - To evaluate the magnitude of the protective effect of the combination of budesonide and formoterol on an as-needed basis compared to the use of terbutaline as-needed on exercise induced bronchoconstriction in adults and adolescents with mild intermittent asthma 2. The secondary objectives of this study are: - To evaluate the magnitude of the protective effect of the combination of budesonide and formoterol as-needed compared to regular once daily use of budesonide plus terbutaline as-needed on exercise induced bronchoconstriction in adults and adolescents with mild intermittent asthma - To evaluate safety of budesonide/formoterol as-needed, terbutaline as-needed and regular use of budesonide + terbutaline as-needed as terms of adverse event
PUR003 is an inhaled substance that is proposed to assist in the treatment of asthma. Study objectives are to : 1. to evaluate the safety of PUR003 in subjects with asthma, and 2. to evaluate the efficacy of PUR003 in assisting the treatment of asthma.
The purpose of this study is to determine whether clean air administered to the breathing zone with Temperature controlled Laminar Airflow (TLA) during night is effective in the treatment of perennial allergic asthma.
The purpose of this study is to determine whether nocturnal environmental control with Temperature controlled Laminar Airflow (TLA) is effective as add on treatment in patients with perennial allergic asthma.
The purpose of the study is to evaluate the concordance of the most frequently used words by the patients and the physicians to express asthma symptoms and the limitations of daily activities caused by asthma.
The primary purpose of this study is to determine the safety, tolerability and pharmacokinetics of ABT-308 in healthy volunteers and patients with mild to moderate controlled asthma.
The aim of the study is to measure the inspiratory flow that the different patient groups (asthmatic children, adults and elderly, as well as chronic obstructive pulmonary disease (COPD) patients) generate through empty Easyhaler (two versions) and Turbuhaler inhalers. In addition, the handling and acceptability of the inhalers will be compared in asthmatic children.
Background: in various pediatric pulmonary diseases such as asthma, cystic fibrosis or bronchopulmonary dysplasia an increased inflammation is present. Measuring this inflammation is often hardly possible and requires invasive techniques such as bronchoscopy. With the use of exhaled breath condensate (EBC) or exhaled breath (EB) analysis it is possible to measure the inflammation in an non-invasive way. However, there is a great need to further standardise these measurements and to identify possible confounding factors.
