Active clinical trials for "Asthma"

The main objective of this study is to evaluate, in real life, the efficacy of prolonged use (6 months) of Puressentiel Air Purifying Spray with 41 essential oils on the control of allergy-induced asthma in the homes of patients with mild to moderate asthma. This will be performed by evaluating the efficacy of prolonged use (6 months) in the indoor environment on the exacerbation and the symptoms of asthma in patients with mild to moderate asthma. The tolerance of the study patients to spraying in an indoor environment will also be analysed.

In this proof of concept study, the investigators aim to determine if supplementation with coconut oil causes an increase in cholecystokinin and cholecystokinin receptor expression in the airway smooth muscle of lean asthmatics, and whether these changes correlate with changes in airway stiffness (estimated by bronchodilator reversibility, airway reactivity, and airway resistance) or symptom control. The investigators propose a 5 week, single center trial in 20 lean patients with mild asthma (not taking inhaled corticosteroids) aged 18 and older. Subjects will supplement their usual diets with 3 tablespoons of coconut oil, a commercially available oil with high dodecanoic acid content, for 3 weeks. To quantify changes in airway smooth muscle cholecystokinin and cholecystokinin-receptor expression, each subject will undergo bronchoscopy with endobronchial biopsies before and after coconut oil ingestion. For the secondary analysis, subjects will also complete spirometry with bronchodilator testing, methacholine challenge, body plethysmography, and an Asthma Control Questionnaire (ACQ) before and after the dietary intervention. This information will be used to compare the changes in airway smooth muscle cholecystokinin and cholecystokinin receptor expression to changes in bronchodilator reversibility, airway reactivity, airway resistance, and symptom control. In the exploratory aims, the investigators will correlate the changes in airway smooth muscle cholecystokinin and cholecystokinin receptor expression with changes in FEV1 and peak flow measurements. The investigators therefore hope to elucidate information about the mechanistic role of cholecystokinin in airway smooth muscle stiffness and contraction.

The goal of this observational study is to 1)analyze the basic information of confirmed cases of asthma in children aged 5-12 years old hospitalized in the First Affiliated Hospital of Guangzhou Medical University from 2009 to 2020, 2)investigate the onset of asthma after 13 years old, 3)conducte lung function, blood and airway inflammation indicators, blood IL13 and IL1RL1 levels, 4)analyze the prognosis and influencing factors of children with asthma in this age group.Participants will be asked to fill a case report form and questionnaires. Besides, they should provide examination results like lung function, total IgE, expired nitric oxide, blood and sputum granulocyte counts, and determination of blood IL13 and IL1RL1 levels over the past 6 months.

The primary objective of this pilot study to is to determine the overall impact of a clinical program of remote medication monitoring administered by St. Mary's Homecare on disease control in pediatric asthma patients. The central hypothesis is that a short-term program of remote asthma medication monitoring paired with home visits and asthma education will be associated with a sustained improvement in asthma symptom control in children over time.

Underdiagnosis and undertreatment is a major problem in childhood asthma management, especially in preschool-aged children. Current prognostic approaches using risk-score based tools have poor-to-modest accuracy, are impractical, and have limited evidence of efficacy in clinical settings and hence are not widely used in practice. The objective of the study is to determine the usability, acceptability, feasibility, and preliminary efficacy of the childhood asthma passive digital marker (PDM) among pediatricians. The study will include practicing pediatricians within the IU Health Network.

Prospective, randomised, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of polymerized and mannan conjugated allergen extract of Dermatophagoides for the treatment of allergic rhinitis/rhinoconjunctivitis with or without asthma. The main objective of the clinical trial is to evaluate the clinical efficacy of the investigational medicinal product, administered sublingually, compared to placebo for the treatment of moderate-severe rhinitis/rhinoconjunctivitis with or without mild to moderate asthma and controlled using the Rhinitis/Rhinoconjunctivitis Combined Symptom and Medication Score (R-CSMS).

National clinical trial, phase III, multicenter, single-arm, efficacy study, 80 participants of both sexes, aged equal or more than 12 and less than 65 years. The group will use Busonid® (budesonide 200mcg and 400mcg) one application (inhalation) of 200 mcg every 12 hours (400mcg / day). During follow-up visits if the participant has not shown an increase in forced expiratory volume in one second greater than 12% and greater than 0,20L or 200ml in spirometry compared with baseline visit, will increase the dose to 800 mcg / day (2x 400 mcg day). The study aims to revalidate by the National Health Surveillance Agency (ANVISA) the registration of the drug Busonid® which there is a vast scientific literature on the pre-clinical and clinical evidence that the efficacy and safety of budesonide. Thus, outlined is a single-arm study, which is applied to the study of the group of participants the same intervention for a certain period and the participants are evaluated for response.

To establish efficacy and safety of HDM sublingual Immunotherapy (HDM-SLIT) by comparing Odactra and placebo, when given sublingually for 3 years to high risk infants aged between 6 to 12 months at enrollment in preventing the development of asthma, assessed 1.5 years after discontinuation of treatment.

This is a prospective, observational clinical cohort study involving 405 children born premature (at less than 37 weeks gestation) and their mother/parent/guardian. The purpose of the study is to investigate how the microbiome (the collection of microbes in a biological site) of children develops over the first years of life and its associations with the risk of childhood health outcomes including allergies and asthma. The study will also examine how perinatal factors associate with patterns of microbiome development, and their effects on the microbiome, metabolome (the collection of metabolites in a biological sample) and immune development of this population in the first years of life.

The overall goal of the Asthma Inflammation Research [AIR] Translational Program is to create an integrated multidisciplinary team for the focused purpose of development of diagnostic and prognostic tests informative for airway inflammation, and for the design of innovative, targeted biologic therapeutics. The overarching aims of the AIR program are to conceptualize, develop, and test the next-generation therapeutics, and novel asthma diagnostic and prognostic tools that will allow us to improve the standard of asthma care.
