Filter by: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.
This project aims to develop a PROM for preschool children with recurrent wheeze. Nearly one third of children will have at least one episode of wheeze in the first five years of life. The majority of these children grow out of the condition in early school years. However, their families go through challenging times often with numerous emergency department admissions and hospitalizations. Hospital admission rates for preschool children with wheeze attacks remain high and are increasing in the UK. New treatments have become available, but although current treatments speed recovery from a wheeze attack, still many children visit hospitals for rescue medications and medical reviews. Recent Australian data show that one fourth of these children remain at emergency departments for a less than four hours period, suggesting that with better information and education, these children could have remained at home. Justification-Significance of the work By understanding what really matters for these families, clinicians and stakeholders will be better able to design interventions that will reduce the hospital attendances and admissions by empowering parents to manage their children's condition. More specifically, this tool will assist GPs identify which of these children need to be reviewed by specialists, aid holistic management, ensure interventions are meaningful for families and assess the benefits of novel treatments. Methodology The items of the questionnaire have been generated through discussions with families in a qualitative research study conducted by the research team. These items will be refined and the questionnaire will be tested with families in different healthcare settings. Researchers will assess how well this questionnaire is identifying the children who present with greater number of hospital admissions and will be benefited from suggested interventions. The data will be analysed and based on the results, amendments will be made to the questionnaire, which can will then be introduced in the routine management of these children.
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.
The goal of this research is to determine whether 10-weeks of exercise training can benefit asthmatic children and young adults with a history of exercise-induced bronchoconstriction (EIB). The investigators will also study an exciting newly discovered aspect of gene expression regulation in the white blood cells known as epigenetics: a process that takes place when genomic changes happen as a result of exposure to the environment. This study is based on emerging exciting new data from this and other laboratories demonstrating that (a) white blood cells play an important role in bronchoconstriction in children, (b) gene and cytokine expression in circulating white blood cells are abnormal in asthma and (c) brief exercise may change genomic and inflammatory- profiles of these cells.Physical activity is an essential component of growth and health in children, thus, this research will lead to improved clinical uses of exercise as preventive and adjunctive therapy in the current epidemic of childhood asthma
Studies of the importance of the human microbiome have demonstrated that microbial metabolites of fermentation of our dietary products (e.g. dietary fiber) have a multitude of health benefits. The investigators aim to determine whether supplementation of asthmatic children with soluble corn fiber alongside standard of care reduces airway inflammation driven by the gut microbial metabolites acetate, propionate, or butyrate (short chain fatty acids).
There is large heterogeneity in treatment response to asthma medication and a one-size fits all approach based on current guidelines might not fit all children with asthma. It is expected that children with one or more variant alleles (Arg16Arg and Arg16Gly) within the beta2 adrenergic receptor (ADRB2) gene coding for the beta2-receptor have a higher risk to poorly respond to long-acting beta2-agonists (LABA) comparing to the Gly16Gly wildtype. Aims To study whether ADRB2 genotype-guided treatment will lead to improvement in asthma control in children with uncontrolled asthma on inhaled corticosteroids compared with usual care. Design A multicentre, double-blind, precision medicine, randomized trial will be carried out within 20 Dutch hospitals. 310 asthmatic children (6-17 years of age) not well controlled on a low dose of inhaled corticosteroids (ICS) will be included and randomized over a genotype-guided and a non-genotype-guided(control) arm. In the genotype-guided arm children with Arg16Arg and Arg16Gly will be treated with double dosages of ICS and with the Gly16Gly wildtype with add on LABA. In the control arm children will be randomized over both treatment options. Lung function measurements, questionnaires focussing on asthma control (ACT/c-ACT) and quality of life, will be obtained in three visits within 6 months. The primary outcome will be improvement in asthma control based on repeated measurement analysis of c-ACT or ACT scores in the first three months of the trial. Additional cost effectiveness studies will be performed. Conclusion Currently, pharmacogenetics is not used in paediatric asthmas. This trial may pave the way to implement promising results for genotype-guided treatment in paediatric asthma in clinical practice.
Bronchial Asthma is a common childhood chronic disease characterized by chronic inflammation of the airways. Frequent relapse of asthma has serious impacts on the child's growth, impairs quality of life (QoL) and mortality, posing a huge economic burden on both family and society. According to Traditional Chinese Medicine (TCM) principles and theory, the main reason for children suffering from asthma are congenital deficiencies at birth which were not corrected and/or lack of appropriate care in the early childhood, leading to insufficiency of the lung, spleen and kidney, resulting in susceptibility to external pathogenic factors. During the interval phase of the illness, wheezing is not prominent and the "Lung-Spleen Qi Deficiency" (LSQD) syndrome is most commonly seen. TCM treatment aims to strengthen the body's immune system by nourishing the spleen, replenishing "Qi"(vital energy), tonifying the lungs and strengthening the exterior, thereby reducing incidences of relapse and improve QoL. It is hypothesized that TCM has adjuvant roles in the management of mild-moderate childhood asthma. Hence the primary aim of this study is to investigate the efficacy of using herbal TCM as adjuvant therapy in the management of symptoms and QoL in asthmatic patients. A randomized, double-blind cross-sectional, 2-arms placebo-controlled study will be carried out. Pediatric patients with mild-moderate asthma identified with LSQD will be randomized to either control or treatment group. Study participants in control group will continue their conventional western medicine (CWM) while those in TCM group will consume a decoction of herbal TCM for 12-weeks in addition to their CWM. Pulmonary function tests, Asthma Control Test, QoL and TCM questionnaires will be used as outcome measurement tools. In addition, liver and kidneys functions will be monitored for signs of toxicity.
Obesity is recognized as a pro-inflammatory condition associated with multiple chronic diseases, including asthma. The specific mechanisms linking asthma and obesity remain hypothetical. Our primary hypothesis is that inflammatory SNPs may regulate the degree of the inflammatory response, with obesity modifying the severity of the disease. In this instance, asthma that develops in the context of obesity demonstrates the potential deleterious relationship between a specific proinflammatory state (obesity) and the genetic regulators of inflammation (SNPs). Our secondary hypothesis proposes that short-term (12-weeks) weight loss by diet alone, but not exercise alone, will reduce lung specific inflammation and diminish the pro-inflammatory responses in female African American obese adolescents with asthma compared to a waiting list control group who after their initial 12 weeks then receive a combined 12-week diet plus exercise program (waiting list control/combined). A third exploratory hypothesis proposes that the frequency of identified SNPs will be significantly related to the amount of fat loss through diet, exercise or combined program and will further be mediated by specific airway and, pro-and-anti-inflammatory markers.These hypotheses will be tested using the following Specific Aims: 1. To determine the frequency of single nucleotide polymorphisms and SNP haplotypes in pro- and anti-inflammatory genes in female African American obese and non-obese asthmatic and non-asthmatic adolescents, 13-19 years or age. 2. To examine the effects of diet or exercise on lung specific inflammation (exhaled nitric oxide, [eNO]) and pro-and-anti-inflammatory responses in female African-American obese asthmatic and non-asthmatic adolescents compared to a waiting list control/ combined group. In addition we will examine the following Exploratory Aim: To determine the effects of the inflammatory SNPs in the modulation of several inflammatory markers and lung specific inflammation (eNO) in female African-American obese asthmatic and non-asthmatic adolescents before and after weight loss through diet, exercise or both.
The primary goal of this proposal is to use an in-home, smartphone-enabled, hand-held spirometer to determine the FEV1% predicted ranges that predict the Yellow Zone threshold.
