Active clinical trials for "Asthma"

Many children have asthma and this causes problems with their health. A lot of children with uncontrolled asthma use emergency departments for asthma care, and so this is an ideal place for an intervention for these children. One intervention is prescribing inhaled steroids to children with uncontrolled asthma, but currently this is rarely done in the emergency department. Inhaled steroids have been shown to be good at making children better long-term when they have uncontrolled asthma. This study identifies children in the emergency department with uncontrolled asthma using a tool called the Pediatric Asthma Control and Communication Instrument (PACCI). If children meet criteria for uncontrolled asthma they will be randomly assigned to either: 1) routine asthma care which includes close follow up with their doctor or 2) prescribing of an inhaled corticosteroid from the emergency department. The investigators hypothesize that children who are prescribed inhaled steroids for uncontrolled asthma from the emergency department will have better 6 month asthma control than children who receive routine asthma care.

The purpose of this study is to determine whether Benralizumab reduces the number of asthma exacerbations in patients who remain uncontrolled on medium doses of ICS-LABA.

The investigators propose to study the patterns of metabolite changes in subjects with asthma to determine if there is a predictable pattern prior to, and post, clinical exacerbation. Hypothesis: 1. Metabolite profiles will change prior to detection of a clinical exacerbation in subjects with asthma. 2. There will be a measurable temporal delay before metabolite profiles return to baseline following anti-inflammatory therapy of an exacerbation of asthma.

It is unknown whether surgical treatment of chronic sinusitis improves asthma control in patients with poorly controlled asthma. This is a randomized trial of surgical plus medical sinus therapy versus medical therapy alone.

Assessment of cardiovascular disorders using echocardiography and arterial stiffness; comparative noninvasive assessment of volatile organic compound (eVOC) exhale breath patterns in patients with different chronic respiratory diseases with age and gender-matched healthy adults in order to identify a disease-specific exhaled eVOCs profiles and markers of respiratory and cardiovascular disorders.

The purpose of this study is to assess the use of a mobile health intervention to improve adherence to asthma medication among adolescents. The intervention consists of an inhaler sensor strap to monitor asthma inhaler use and a mobile phone application to remind and incentivize patients to use their medication. This study will assess medication use throughout the study in patients who receive a mobile app with reminders and asthma control as measured by the ACT [asthma control test].

This study is a double-blind, parallel-group, randomized study of active drug vs placebo in asthma.

This study will last up to 9 weeks. Subjects will visit the clinic up to 14 times. Certain clinic visits will include a physical examination, lung function tests, inflammatory cell analysis from nasal secretions and/or sputum, and blood draws. Subjects will inhale an FDA approved virus through their nose which is known to cause the common cold. All study related medications and medical examinations will be provided at no cost to the subject. The drugs used in this study are approved for the age group under study.

Our research group has found that Canadians with undiagnosed asthma or chronic obstructive pulmonary disease (COPD) have increased respiratory symptoms and worse health-related quality of life. The investigators recently developed and validated an on-line questionnaire to accurately identify these symptomatic, undiagnosed individuals. The investigators will advertise in the community asking individuals to complete the on-line questionnaire at home, at their leisure, to determine if they are at risk of asthma or COPD. Those at risk will be invited to participate in our randomized, controlled clinical trial to determine if guidelines-based treatment of newly discovered undiagnosed asthma or COPD will improve their quality of life and clinical outcomes.

Study of the palatability and acceptability of dexamethasone oral tablets crushed and placed in apple sauce or pudding in comparison with the IV solution mixed with sugar syrup and given orally. It is hypothesized that dexamethasone tablets crushed and administered in apple sauce or pudding will be more palatable and acceptable for pediatric patients receiving dexamethasone for an acute asthma exacerbation or croup.
