Indoor Air Quality Asthma Study: The Effect of Indoor Air Quality and Mitigation of Same on Persistent...

Persistent Asthma

The primary objective is to determine whether continuous sensing, control and mitigation of home indoor air quality influences the frequency of asthma related symptoms, as measured by Serum IgE, Spirometry with exhaled Nitric Oxide, missed school and workdays, need for pharmacologic intervention (albuterol, oral steroids), frequency of sick visits to pulmonologist or primary care provider (PCP), urgent care / emergency department visits, and hospitalizations

Asthma

This study will assess whether switching participants who have benefitted from mepolizumab or benralizumab to GSK3511294 (Depemokimab) is non-inferior to maintaining current treatment on the annualized rate of clinically significant exacerbations in participants with severe asthma with an eosinophilic phenotype. Throughout the study, all participants will continue their non-biologic Baseline standard of care (SoC) asthma treatment.

The Use of Home Spirometry in the Monitoring of Patients With Acute Exacerbation of Asthma

Asthma Attack

After outpatient clinic visit, asthmatic patients with worsening of symptoms (including dyspnea, wheezing, chest tightness, cough, activity limitation, awaken in the midnight due to discomfort) and are diagnosed of acute exacerbation by physician, will be recruited. The patients are asked to record symptoms using asthma symptom diary (ASD) with home spirometry simultaneously for 14 days. Visit 1 (day 1) All patients will be evaluated the following: Record the patients' demographics (age, gender, race), baseline characteristics, comorbidities, health care resources use (visits, lab tests, hospitalization and cost), pharmacological and non-pharmacological treatments Blood sampling for eosinophils, eosinophil cationic protein (ECP) and immunoglobulin E (IgE) as clinically indicated (if no data available within one year for the last two) The study assistant will introduce to the patient how to manipulate the home spirometry and its app, and to record the daily asthma symptoms by using the ASD on the mobile phone. Visit 2 (day 15) All patients will be arranged outpatient clinic follow up 2 weeks later from the first visit. The outpatient clinic physician will check the home spirometry report and ASD symptom score in the past 2 weeks, and have a well explanation of these results. Statistical analysis The usage of digital function including input ASD, and the lung function from portable spirometer in study arm will be demonstrated by descriptive statistics.

5HTP Regulation Of Asthma In Children

Mild or Moderate Asthma With Allergic Sensitization

The purpose of this study is to learn more about if taking a supplement called 5-hydroxytryptophan (5HTP) can improve breathing and anxiety symptoms related to asthma. To help learn more subjects will either be assigned to a group that is taking the supplement (5HTP) or a group that is taking a placebo. This will be decided randomly. Later in the study subjects will crossover to the other group.There are 5 study visits over the course of about 12 weeks.

Symptom Clusters in Children With Exacerbation-prone Asthma

Asthma in Children

Pediatric participants with exacerbation-prone asthma will receive an intramuscular injection of triamcinolone acetonide and will be followed for 48 weeks. The study visit 2 weeks after the injection will assess the response to the study medication, while the remaining study visits will examine the temporal stability of the symptom clusters.

Reducing Asthma Attacks in Disadvantaged School Children With Asthma

Asthma in Children

Our UH3 clinical trial, "Reducing Asthma Attacks in Disadvantaged School Children with Asthma," seeks broad-scale implementation of our effective school-based approach to improve asthma disparities for children, ages 5-12 years, in low-income communities. The investigators will contextualize dissemination and implementation (D&I) of our Colorado school-based asthma program (Col-SBAP) that reduces asthma exacerbations and missed school days, while also addressing social determinants of health. Our Better Asthma Control for Kids (BACK) Program will evaluate key metrics identified by diverse stakeholders during this dissemination trial in rural and small metropolitan areas of Colorado. Our clinical trial includes two implementation strategies: our standard Col-SBAP, titled BACK-Standard (BACK-S) and an enhanced community-centered approach, titled Back-Enhanced (BACK-E). These two strategies are designed for sustainable delivery by school asthma navigators and school nurses who coordinate with primary care and community resources. The Exploration, Preparation, Implementation, Sustainment (EPIS) D&I framework was applied with community partners during the UG3 planning phase to tailor implementation plans that meet local community needs, resources and priorities (EPIS Phases 1 & 2). BACK-S and BACK-E will be delivered from years 1-3 with data collection for implementation and effectiveness outcomes in 4 Colorado regions. In year 4, the investigators will collect data for sustainment outcomes (EPIS phase 3). The investigators will apply the work from EPIS phases 1-3 to refine our "dissemination playbook" that guides adoption by other school systems (EPIS Phase 4). Our primary implementation hypothesis is: Reach will be greater among students when delivered using the BACK-E arm as compared to BACK-S. Our effectiveness hypothesis is: BACK will be more effective than usual care at reducing asthma exacerbations. The BACK playbook includes training materials and a calculation of return on investment. The investigators are targeting schools with high levels of uncontrolled asthma and asthma associated burden. Our UH3 trial includes partner engagement to ensure BACK is disseminated to diverse geopolitical areas of Colorado with attention to sustainability. Collectively, our approach will accelerate dissemination of BACK nationally to communities experiencing health inequities in pediatric asthma care.

Periostin-guided Withdrawal of Inhaled Corticosteroids in Patients With Non-eosinophilic Asthma...

Asthma

Background: Asthma is a common chronic condition characterized by respiratory symptoms and hyperresponsive airways. According to treatment guidelines, patients with persistent asthma require daily treatment with inhaled corticosteroids (ICS). However, certain subgroups of asthma patients such as non-eosinophilic asthma patients do not respond well to the ICS treatment. In the present study, asthma patients treated with ICS and exhibiting low levels of eosinophilic biomarkers such as S-periostin, FeNO and blood eosinophils, are randomized 1:1 to either 1) tapering of ICS or 2) usual care. Thus, the aim of the present study is to investigate whether patients with non-eosinophilic asthma can sustain their level of disease control during ICS tapering. Design: This is a randomized, controlled, one-center, non-inferiority study of ICS tapering in patients with non-eosinophilic asthma. Inclusion and exclusion criteria: 1) Objectively secured asthma diagnosis, 2) Age 18-65 years, 3) ICS treatment equivalent to Budesonide 800 microg daily or more with at least 80% adherence, 4) Serum-periostin < 50 ng/ml, 5) FeNO<25 ppb at all prior visits, 6) Blood-eosinophils<0.15 at screening, 7) no allergic asthma history, 8) no daily smoking within 6 months, 9) no other respiratory disease, 10) no daily treatment with immunosuppressives, 11) no pregnancy, and 12) no history of drug or alcohol abuse. Endpoints: Primary: Change in Control Questionnaire (ACQ) from baseline to post-tapered ICS and time from baseline to drop-out. Secondary: Change in FeNO, change in Serum-Periostin, change in FEV1, change in blood-eosinophils. Methods: Relevant patients will be recruited from Respiratory Outpatient Wards. In total, 110 patients will be required. Visits will be performed at screening, at week 0, 4, 8, 12, 16, 26, 52. In the active arm, ICS dosage will be reduced to 50% at week 0 and removed at week 8. All visits include ACQ, FeNO, spirometry, blood eosinophils. S-periostin will be measured at screening and at week 8 and 16.

Vitamin D In the Prevention of Viral-induced Asthma in Preschoolers

Asthma

In this 7-month randomized controlled trial, children aged 1 to less than 6 years, with recurrent asthma attacks triggered mostly by colds, will receive a high dose of vitamin D or a placebo every 3.5 months during their usual clinic visit, and a daily supplement of vitamin D or a placebo. This study will test whether children in vitamin D group have less frequent and less severe asthma exacerbations compared with those receiving placebo.The study will also document the safety profile of this strategy.
