Active clinical trials for "Asthma"

The purpose of this study is to investigate the relationship between long-term use of systemic steroids in patients with upper and lower respiratory tract diseases and their own production of cortisol (cross-sectional), as well as whether those with low cortisol levels have an impact on bone density. As patients with CRSwNP have a high use of steroids, they routinely undergo a DEXA scan at the Respiratory Clinic, Department of Ear-Nose-Throat Surgery and Audiology (ENT) - Rigshospitalet (RH) to examine whether their bone density and structure are affected. The scan will be included as a clinical secondary outcome to assess whether systemic steroid use has an impact on this. The purpose of the study is therefore to compare steroid intake, baseline P-cortisol, the body's response to ACTH (measured by cortisol levels after the test), and bone density in patients with chronic sinusitis (CRS) with and without asthma in an unselected population at the Respiratory Clinic (cross-sectional). In addition, at the 4-month follow-up (exploratory follow-up, pilot project), it will be investigated whether good adherence (>80%) to inhalation therapy (nasal steroid and lung steroid) and additional treatment with biologicals has a negative effect on the body's own production of P-cortisol.

Exacerbations of asthma (asthma attacks) are very common in the UK. They are frightening for patients, expensive for the health service, and occasionally lead to avoidable deaths. Despite the obvious importance of asthma attacks, they remain poorly understood. Although some of the triggers for attacks are known, the resultant characteristics of attacks are not. Recent research has shown different inflammation profiles associated with asthma attacks; however, this is not well understood, and all asthma attacks are treated the same. Increased knowledge about the nature of asthma attacks may better define these attacks and help develop more targeted treatment options. This study aims to describe the characteristics of patients admitted with asthma attacks. The recovery and response to standard treatment for asthma attacks following discharge from the hospital will also be described. This is achieved by studying the characteristics of asthma attacks in patients hospitalized with acute asthma. Participants will be asked to attend two follow-up visits during which their response to treatment will be described. The study is planned to last for 2.5 years, with a recruitment period of 18 months, and will include 100 participants with acute asthma.

This is a multi-center, non-interventional registry to create and maintain a database of participants to serve as a recruitment source for current and future DAIT NIAID-sponsored Childhood Asthma in Urban Settings (CAUSE) studies.

Prospective, randomized, placebo-controlled, multicenter of 3 active treatment groups, compared to 1 placebo group, for the determination of the efficacy and safety of subcutaneous immunotherapy in patients with mild to moderate asthma and rhinitis/rhinoconjunctivitis (intermittent or persistent) allergic to Dermatophagoides pteronyssinus and/or Dermatophagoides farinae.

Improving Medication Adherence with Telehealthcare Medication Therapy Management to Change Health Outcomes in Adolescents and Young Adults with Asthma (MATCH) is a multi-center, randomized parallel group study targeted to an at-risk population of Adolescents and Young Adults (AYA) with uncontrolled asthma who have poor adherence with prescribed Inhaled corticosteroid (ICS) therapy.

This is a prospective, observational, exposure cohort study of pregnancy and infant outcomes in women with asthma exposed to benralizumab anytime during pregnancy, or within 8 weeks prior to the first day of the last menstrual period (LMP) The objective of the study is to monitor planned or unplanned pregnancies to evaluate potential teratogenic effect (birth defect) when exposed to benralizumab compared to two unexposed comparator groups. The primary outcome is major structural birth defects (abnormalities in development of structures of the body) and the secondary outcomes are preterm delivery (premature baby), small for gestational age infants (small for weight, length, and/or head circumference), spontaneous abortion (miscarriage), stillbirth (baby born without signs of life), elective termination (voluntary abortion) and small for age postnatal growth to one year of age (small for weight, length and/or head circumference). The birth prevalence or incidence of outcomes in women exposed to benralizumab, and their infants, will be compared to those observed in two unexposed comparator groups: a disease-matched comparison group of women who have not used benralizumab during pregnancy or within 8 weeks of their last menstrual period (LMP), but who have used other anti-asthmatic medications (treated disease comparison group), and a comparison group of healthy women who do not have a diagnosis of asthma, have not had exposure to a known human teratogen (substance that causes birth defect), and have not taken benralizumab in pregnancy (healthy comparison group).

The anti-interleukin (IL)-5 receptor benralizumab inhibits eosinophilic inflammation but its potential effect on airway remodeling remains unknown. The main objective of this study is to assess the effect of benralizumab in an in vitro model of airway remodeling using cells obtained from asthmatic patients.

Inhaled corticosteroid (ICS) is considered the first line medication for asthma, however, the therapeutic effect is markedly different even in patients with almost similar clinical manifestations. Our study was designed to explore the clinical and genetic factors that may influence the effectiveness of ICS in asthmatic children.

The goal of this observational study is to learn about clinical and functional outcomes in patients with Chronic rhinosinusitis with nasal polyps and comorbid Severe Eosinophilic Asthma and patients with Chronic rhinosinusitis with nasal polyps only treated with mepolizumab compared to healthy controls. Participants will be asked to give nasal, blood and sputum samples before mepolizumab administration (T0) and at 3 (T3), 6 (T6) and 12 (T12) months after mepolizumab initiation The main aims are to identify airways microbiota modifications and differential gene expression after mepolizumab initiation. Researchers will compare: Patients with Chronic rhinosinusitis with nasal polyps and comorbid Severe Eosinophilic Asthma Patients with Chronic rhinosinusitis with nasal polyps only Healthy subjects The research will address the following questions: What are the prospective clinical and functional outcomes of mepolizumab treatment What is the impact of mepolizumab therapy on the airways microbiota and how this may relate to a potentially reduced need for steroids What are the host differential gene expression patterns and the immune/inflammatory (cytokines/chemokines) profile alterations in airways microenvironment and in systemic circulation in response to therapy What are the associations between host and microbiome variables for building up diagnostic and predictive biomarker classifiers of responsive disease endotypes

The goal of this research trial is to develop and evaluate a stakeholder-driven approach to optimize implementation of the School-based Asthma Therapy (SBAT) program for sustainable improvement in adherence to guideline-based care and reduce health disparities for children with asthma. We will compare basic implementation (BI) to enhanced implementation (EI) based on stakeholder-informed strategies. The EI strategies will include support to school-health staff to facilitate the following components: 1) telemedicine asthma visits through school with primary care and/or specialist providers to prescribe initial preventive medications and step-ups, 2) school-based directly-observed-therapy (DOT) of preventive asthma medications, 3) follow-up telemedicine asthma control assessments, and 4) centralized case management as needed.
