Introduction : . In Oman the prevalence of asthma was estimated to be 7.3% of adults and 12.7% of children . Magnesium sulphate is the second line treatment, many studies had shown that it has beneficial effect in treating acute asthma in children ; it reduces the hospital stay and the rate of admission as well as the ventilation rate . Aim : To compare single dose Magnesium sulphate that is typically given in the emergency department verses two doses of magnesium sulphate in treating acute moderate-severe asthma exacerbation in paediatric age group Research hypothesis : Children who are treated with two doses MgSO4 are more likely to have improvement in their PRAM score and are less likely to be admitted to the ward, HD or ICU Primary outcome : Improvement in PRAM (Paediatric respiratory assessment measure) score of acute asthma exacerbation Secondary outcome : Reduce admission rate to general ward, PICU and HD . Demonstrate the safety profile of double dose of magnesium sulphate. Study Design : prospective blinded randomized trial Study population : children age 3-13 years who presented to Royal hospital paediatric emergency with moderate-severe acute asthma Intervention : two doses magnesium sulphate Comparison : Placebo Outcome : Improvement in PRAM score
Asthma is the most common respiratory disorder in children that causes breathing problems. The patients may have respiratory symptoms such as cough, wheeze, or short of breath. Asthma can be mild or severe when daily activities become compromised. Generally, by application of proper treatment, asthma symptoms can be well controlled. However, the exacerbation of the disease often leads to acute respiratory adverse events that require hospitalization and school absenteeism. In this study, we plan the remote monitoring of lung function parameters in asthmatic children (under 18 years of age). We hypothesize that the daily home monitoring of respiratory indices will predict the occurrence of exacerbation and the hospitalization can be lowered. Asthmatic children arriving for the regular examinations to the Department of Pediatrics and Pediatric Health Care Center of the University of Szeged will be involved. The patients are randomly divided into two treatment groups, telemonitoring and control. For both groups, general patient characteristics will be recorded, and lung function parameters will be measured with a clinical spirometer. Patients in the telemedicine group receive the home mobile controlled spirometer and trained by a pediatric pulmonologist for home examination. The spirometers are handed for 12 months, and children are asked to perform measurements minimum 4 times per week (at least one day a week in the morning and in the evening). In the case of asthma attacks, more frequent measurements repeated several times a day are required. Children in the telemedicine group complete the Asthma Control Test (ACT) after each measurement, which provides a numerical score related to the severity of asthma symptoms. Lung function parameters measured by children and the ACT results are automatically uploaded to a clinical server where the pulmonologists and built-in algorithms are monitoring the quality of the data. In case of deterioration of the lung function parameters, the patients are called for a personal visit and their treatment can be revised. Every three months, members of both groups come to the outpatient clinic for a personal visit, where the same examinations are performed.
Due to a large disease heterogeneity, the proper management of childhood asthma may be a challenging task. Despite the screening of lung function is a fundamental tool, spirometry alone may not allow a reliable prediction of the disease prognosis, such as treatment response and asthma exacerbations. Recently, it has been shown that the detection of volatile organic compounds (VOCs) in exhaled breath (Breathomics) is able to predict asthma exacerbations and to discriminate children with persistently controlled asthma from those with uncontrolled asthma. These studies have been realized through gas chromatography / mass spectroscopy techniques, which also provide information on specific compounds useful for pathophysiologic research; however, they are expensive and time consuming. An alternative approach, scarcely adopted so far, is based on cross-reactive nonspecific sensor arrays (e-noses), which may provide valuable information on disease status through pattern recognition algorithms or discriminant analyses of the global sensor response pattern (breath-fingerprint). In particular, the Pneumopipe® (European patent 12425057.2, Rome, Italy) is a recent and innovative device allowing direct absorption of VOCs on a cartridge after an individual has normally breathed in it for 3 min. It is a very simple and cheap procedure, suitable for non-collaborative populations. Moreover, cartridges may be preferable over sampling bags in terms of preservation and transportability. This modern breath sampling system provides repeatable measurements, and negligible overlap has been observed with information provided by spirometry. The main objective of the present study is to assess whether baseline (pre-treatment) spirometry and e-nose measurements may predict asthma prognosis in persistent asthmatic children, in terms of response to the prescribed treatment with inhaled steroid (ICS), and to provide simple rules for discriminating treatment responders and non-responders. The secondary aim is to assess e-nose ability to predict asthma exacerbations, disease control and adherence.
This study evaluated the efficacy of doxophylline as a steroid sparing treatment in Mexican children with asthma treated with medium ir high doses of inhaled corticosteroids (ICS). It is a cross over study in which both groups of patients will receive doxophylline plus a lower steroid dose maintaining the same treatment step according to GINA guidelines, one group will maintain the same treatment dose while the other will start with doxophylline with the lower ICS dose, and by the middle of the study both groups will interchange treatment schemes.
Respiratory Syncytial Virus (RSV) is a leading cause of childhood illness and hospitalization across the world. In addition to acute mortality and morbidity, RSV infection is associated with developing recurrent wheeze in pre-school children and asthma in later life. The overarching aim of the study is to demonstrate the long-term effect of RSV infection on child health in resource-poor settings. Children previously infected with RSV in their first two months of life and age-matched controls will be followed and epidemiological data will be compared in terms of prevalence of asthma, lung function status, physical growth status, and asthma risk factors. Enrolled children will be routinely assessed for a period of 12 months. During this period, this study will record the health status of the children (respiratory tract illness, wheeze, cough, other illness, and attendance at medical services), physical growth (height, weight and mid-upper arm circumference), family history of atopic diseases (e.g. asthma) and environmental risk exposure (indoor tobacco smoke, crowding, and cooking fuels, cooking place) among enrolled children. Where the acute asthma exacerbation will be suspected, physicians will assess the lung condition of the enrolled sick children using stethoscope and peak flow-meter. The lung function of children will be measured using spirometry, hyper-reactivity against common allergens will be performed using skin prick methods, exercise challenge test will be performed to understand the airway hyperresponsiveness, and blood eosinophil count determine the eosinophil level in the peripheral blood.
Exhibiting variable airway obstruction is a key factor in the diagnosis of asthma but too often it is undetected by spirometry. Study hypothesis: The forced oscillation technique (FOT) will show airway obstruction in asthmatic children with normal spirometry pointing out its advantage in measuring AW obstruction in this population. We will conduct a prospective observational study in 6-18 years old children with the diagnosis of asthma and a normal spirometry results. Each subject will undergo evaluation including: asthma control questionnaire, spirometry, FOT and Fractional exhaled nitric oxide (FeNO) to assess the sensitivity of FOT in diagnosing airway obstruction in this circumstances.
This study is a multi-center randomized controlled trial of children with asthma. The objective of the study is to assess the efficacy of China Children Asthma Action Plan (CCAAP), which is the first asthma action plan for children with asthma in China, in asthma management.
Acute asthma produces greatly increased work of breathing and increased oxygen requirement secondary to bronchial narrowing and airway obstruction by inflammatory secretions. There is growing evidence that non-invasive ventilation can reverse these processes more efficiently than conventional asthma therapy. Surprisingly, there have not yet been any large scale prospective controlled studies to investigate this hypothesis, (either in adults or children). Consequently, the aim of this study is to determine if the use of non-invasive positive airway pressure, for children admitted to hospital with an acute exacerbation of asthma, reduces their work of breathing, need for adjunctive medications, and shortens the length of hospital stay, compared to current standard therapy.
