Active clinical trials for "Respiratory Sounds"

This study evaluates the effect of cumulative dose administration of albuterol sulfate inhalation aerosol delivered with valved holding chamber and facemask. This is a four week study in birth to 23 month old subjects who are experiencing acute wheezing due to obstructive airways disease.

The INFANT study will test whether, in preschool children 12-59 months of age with persistent asthma, the following Step 2 asthma therapies will provide similar degrees of asthma control: Daily inhaled corticosteroid (ICS) treatment, Daily leukotriene receptor antagonist (LTRA) treatment, and As-needed ICS plus short-acting beta agonist (as-needed ICS/SABA) rescue treatment.

The purpose of this study is to determine if adding nebulized budesonide to the systemic steroid for treatment of acute wheezing has any additive benefit in children who have hospitalized for acute wheezing.

The purpose of this study is to determine if adding nebulized budesonide to the systemic steroid for treatment of acute wheezing has any additive benefit in the emergency room.

The purpose of this study is to evaluate the efficacy and adverse effect of nebulized corticosteroid to prevent post-extubation stridor in children.

This is a prospective randomized, open label clinical trial in approximately 300 children aged 5-11 years with a physician diagnosis of persistent asthma. Participants will be randomized 1:1 to receive either a single intranasal dose of licensed quadrivalent LAIV (LAIV4) or an intramuscular injection of quadrivalent IIV4 (IIV4).

Subjects aged 1-8 years who have been discharged from the emergency department/outpatient care facility with a diagnosis of asthma/bronchospasm/wheezing after usual standard care will be enrolled into this open-label, randomized, parallel-group study to compare the efficacy of nebulized budesonide and oral corticosteroids in preventing asthma exacerbation relapse rates during the 21-day follow-up period.

Wheezing is a high-pitched whistling sound that is produced when air flows through narrowed lung airways. It is a common symptom of asthma. Persistent wheezing is commonly treated with bronchodilators and inhaled steroids; however, when wheezing is temporarily caused by a virus or exposure to tobacco smoke, this may not be the most effective treatment. The purpose of this study is to evaluate the cause of wheezing in infants and children and to assess the effectiveness of inhaled steroids on improving lung function.

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.
