Filter by:The primary objective of this study is to evaluate budesonide levels in the blood following inhalation of single doses of VR647 Inhalation Suspension in children with wheezing, reactive airway disease or mild asthma using a nebulizer, the VR647 Inhalation System. Secondary objectives include the evaluation of the safety and tolerability of VR647 Inhalation Suspension administered using the VR647 Inhalation System. The study consists of four visits; a screening visit (Visit 1), two dosing days (Visits 2 and 3) and a follow-up visit (Visit 4). On each dosing day a single dose of treatment will be administered. Treatment allocation at Visits 2 and 3 is determined by a balanced incomplete block design.
This study evaluates the value of impedance pneumography, used as overnight home recordings during a longitudinal design, in assessing asthma control in preschool children
In a randomized clinical trial (RCT) published in JAMA, the investigators have provided evidence that vitamin C supplementation (500 mg daily during pregnancy) ameliorates the effects of maternal smoking during pregnancy on offspring lung function and subsequent incidence of wheeze by 48% through 1 year of age. The investigators are currently completing a second RCT of vitamin C supplementation in pregnant smokers with more robust measures of pulmonary outcomes. The purpose of this ECHO application is to combine these 2 focused, interventional cohorts to allow critical longitudinal follow-up of respiratory outcomes in these children including the study of pulmonary function test (PFT) trajectories and incidence of recurrent wheeze/asthma from infancy through early adolescence in offspring of pregnant smokers randomized to vitamin C versus placebo.
The overall aims of this protocol are to determine whether prenatal supplementation with vitamin C to pregnant smokers can improve pulmonary function and decrease wheeze at 5 years of age in their offspring. This is a continuation of the VCSIP trial, to follow the offspring through 5 years of age. The hypothesis for this protocol is an extension of the VCSIP trial that supplemental vitamin C in pregnant smokers can significantly improve their children's PFTs and decrease the incidence of wheeze.
This study evaluates the effect of intermittent tiotropium bromide and salbutamol as needed versus intermittent fluticasone propionate and salbutamol as needed, or solely, salbutamol as needed on episode-free days in infants and toddlers with recurrent episodes of wheeze and/or shortness of breath.
Reactive airway diseases is a common respiratory diseases affecting 1-18% of the population in different countries. It carries a significant burden to children, their families, the healthcare system and the overall community.The purpose of the study is to delineate the prevalence of abnormal nasal finding in wheezy children and evaluate the role of the endoscopic examination of the nose in evaluation and management of a wheezy child.Patients and methods:The study will be conducted as a prospective case series including all children having chest wheezes, aged from two years to eighteen years, attending emergency unit of assuit university children hospital
This study will investigate the interaction between GSTP1 / TNFa polymorphisms and passive smoking in children with asthma/wheezing. Contemporary second hand-smoke exposure will be confirmed by laboratory testing.
Vitamin D deficiency is highly prevalent in the UK. Research shows that vitamin D enhances the immune system and may help protect against chest infections that can cause wheezing illness or worsen asthma symptoms. The Department of Health recommends a dose of 10 micrograms of vitamin D/day to prevent severe vitamin D deficiency in children. However, many studies have reported that this dose is not enough to raise plasma 25(OH)D concentration to the levels most likely to prevent against worsening of asthma symptoms. Such studies suggest that 25 micrograms of vitamin D/day. This dose is safe but its effects on vitamin D blood levels have not yet been specifically tested in children with asthma/wheeze. This study is designed to determine the optimal oral daily vitamin D supplementation dose to treat vitamin D deficiency in children with asthma or preschool wheeze. Over the 6-month course of the study, participants will meet with the study team four times in clinic or in their own home and will be contacted by telephone five times. Children will be asked to give a drop of blood via a fingerprick to test their vitamin D level and a sample of nasal epithelial lining fluid for measurement of inflammatory markers on three separate occasions.
This is a single-centre, open label study, aiming to evaluate the efficacy of beclomethasone dipropionate applied for 12 weeks with a dose of 400 µg twice a day (total dose 800 µg nebulized), on airway resistance and reactances (measured with Rint and FOT techniques) in children with recurrent wheezing, aged 2-5 years. In addition, clinic score as frequency of symptoms and exacerbations, will be assessed.
Children 2-11 years of age who are given the influenza vaccine (inactivated influenza (IIV) or live attenuated influenza vaccine (LAIV)) as part of their routine care can enroll in this study if their parent has the ability to receive and send text messages. Children enrolled in this study will be observed daily for an eight-day period starting on the day of vaccine administration, and then continuing over the next 7 days, and then weekly for 42 days. On the day of enrollment and nightly for the next seven days, the parent will report via text message what their child's highest temperature is. If fever is present, they will then be prompted for additional information including other symptoms, antipyretic use and medical care sought. On day 3 as well as weekly from day 7 through day 42 post-vaccination, parents will be asked via text message about breathing problems, specifically cough, wheezing and chest tightness. They will also be asked about medications taken and care sought. The purpose of this study is to assess the feasibility of collecting this data.
