Active clinical trials for "Asthma"

This study is a retrospective cohort study of patients diagnosed with asthma based on the data extracted from the MDV database. The study period is from 1st Jun 2016 to 29th February 2020 .

A retrospective database pre-post cohort study, identifying asthmatic patients, aged 6- 11, with omalizumab use over 24 months

The combination of asthma and being a carrier of genetic variants (mutations and / or polymorphisms) in the CFTR gene variant would cause bronchial asthma with mucus hypersecretion. This phenotype is characterized by a more severe disease, in terms of control, quality of life, exacerbations and lung function, and a different asthma the bronchial hypersecretion without inflammatory phenotype.

The aim of this study is to assess the knowledge, the attitudes and the practices of parents of asthmatic children.

The purpose of this study is To estimate the association between prenatal exposure to proton pump inhibitors (PPIs) and the risk of asthma during childhood. To estimate the association between prenatal exposure to H2-receptor antagonists (H2RAs) and the risk of asthma during childhood.

A selection of asthma patients were followed during preparation to climb the Aconcagua mountain. The primary goal of this follow up was to optimize patients' asthma status. Also during expedition, these patients were daily consulted by a physician. All data obtained during preparation and expedition will now be retrospectively analyzed.

The Severe Asthma Research Program III is an NIH cooperative agreement involving 7 clinical centers that encompass a multidisciplinary partnerships between asthma clinician-scientists and scientists with expertise in immunology, pulmonary physiology, molecular genetics, molecular phenotyping, imaging, and bioinformatics. These clinical centers will jointly recruit volunteers with asthma for an observational longitudinal follow-up study. However, centers will also conduct specific mechanistic research projects at each participating institution. The University of Pittsburgh's SARP III study will determine the molecular and clinical stability of asthma phenotypes over time.

Many patients suffering from asthma are not compliant to their treatment and consequently, are not well controlled. Shared decision making intervention has shown an improvement in the outcome of patients with chronic disease. The aim of this study is to evaluate decisional conflict and to assess decisional needs of adults with asthma.

The study was designed to collect data about inadequately controlled moderate to severe allergic asthma in subjects 6 to < 12 years of age, managed in a real-world setting.

The objective of this study is to compare asthma-related exacerbations (emergency department (ED) or inpatient (IP) visit) and related cost in pediatric patients aged 4-11 years that received either fluticasone propionate 44 mcg (FP44) or budesonide (BUD) or montelukast (MON). This retrospective observational cohort analysis utilizes a large managed care database with linked pharmacy and medical claims. Patients with ≥ 1 pharmacy claim FP44 or BUD or MON between January 1, 2000 through June 30, 2008 (4-11 years old at time of index) with ≥ 1 diagnosis for asthma (ICD-9 493.xx) in the pre-index period and continuously eligible to receive healthcare services for 1-year pre-index and at least 30 days post-index. Dose of each inhaled corticosteroid was not known in the database. Follow-up was defined for each patient as the period beginning with the index date and ending with the last date of continuous claims history, switch to another asthma controller medication, or claim for an asthma related event (ED/IP visit or OCS use) post-index, whichever occurred first.
