Active clinical trials for "Asthma"

Bronchial asthma is the most common chronic respiratory disease in children. At present, more attention has been paid to the treatment of airway inflammation and smooth muscle spasm, while the related research on the risk factors of asthma attack, mucus plug formation and its effect on asthma has been ignored. This study was a retrospective study. Children hospitalized for acute exacerbation of asthma from 2016 to 2021 were selected as the research objects. The clinical manifestations, bronchoscopy results and lung CT results of children hospitalized for acute exacerbation of asthma were summarized. To analyze the risk factors of acute exacerbation, clinical characteristics, risk factors of mucus plug formation in hospitalized children with asthma, and the safety and efficacy of flexible bronchoscopy in the diagnosis and treatment of hospitalized children with asthma. The discharged children were investigated by written or online questionnaires to understand the acute attack of asthma, control level, compliance, appliability of the China Children's Asthma Action Plan, family management and medical utilization of children with asthma after discharge.

Asthma is a syndrome compromising many phenotypes including N-ERD (caused by increased 4-series leukotriene (LT) production). n-3 PUFA supplementation modulates 4-series LT and has anti-inflammatory effects. However, other than in a pilot study with dietary manipulation, the effects of N-ERD are unknown. The primary objective is to determine whether n-3 PUFA supplementation in people with N-ERD can improve asthma control using the asthma control questionnaire (ACQ-7). This is a placebo controlled randomised controlled parallel multicentre study with of 6g per day of PUFA for 6 months in people with N-ERD and poor asthma control

SIMAP is a triple-masked randomised trial aimed at assessing whether an automated system of pictograms associated to medical indications results in better comprehension and adherence of said indications. Adult patients with a recent diagnosis of asthma will be randomised to receive a pictographic depiction of their treatments and recommended interventions or standard communication without assistance from their attending physician. Patients will be followed-up for 60 days using the Asthma Control Questionnaire (ACT). The primary endpoint of this study is the degree of asthma control as assessed by the aforementioned questionnaire. Secondary outcomes include the number of hospitalisations, emergency care unit visits and the need to increase bronchodilator therapy as per current Global Initiative for Asthma guidelines. Outcomes will be analysed under the intention-to-treat principle by a statistician unaware of treatment allocation.

The goal of this study is to identify reliable, valid, easily measurable, interpretable, and useful biomarkers in peripheral blood and exhaled air by people with severe asthma for a more accurate description of the pathogenetic processes of asthma-related to the inflammatory endotype and the choice of biologic therapy.

The purpose of the investigation is to confirm the followings under the post-marketing actual long-term use of Tezspire. Development of related AEs Contributing factors possibly having an impact on the safety and effectiveness Development of unexpected related AEs

Our study aiming to look in improvement of Pediatric Respiratory Assessment Measure (PRAM) score as a primary outcome. The secondary outcomes involving the need for second step management, need for admission and possible side effects. It's double blinded randomized control study comparing Nebulized Epinephrine with standard treatment (salbutamol + Ipratropium) versus the standard treatment only in pediatric patient. A pilot study will be conducted before to detect the sample size required and data will be collected at deferent interval post treatment targeting intension to treat for analysis.

Background: - Asthma is a serious clinical and public health problem. Researchers want to collect data to better understand how bacteria and other things in the environment can affect people's asthma. Eligibility: - Nonsmoking adults age 18 - 60 who have moderate to severe asthma. Design: Participants will complete a medical history form before the first visit. Study visits will include collecting medical history, and conducting physical exam, lung and smoking tests. Participants will give blood, urine, stool, dust, saliva, and sputum samples. Participants will take tests that measure their breathing abilities. They will give saliva samples for DNA study. They will get kits to collect stool and dust samples at home. They will fill out surveys. Participants will have visits every 6 months for 5 years. They can schedule sick visits, if needed, at no cost to the participant. For all visits, they will have asthma check-ups and get treatment, at no cost to the participant. Some participants may take part in a sub-study that includes one 4-hour visit. They will have medical history, physical exam, and lung tests. They will have urine tests to check for pregnancy and tobacco exposure. Then they will have bronchoscopy. For this, an intravenous line will be placed in an arm vein. The nose and throat will be numbed. A flexible fiber-optic tube will be inserted into their airways through the nose. Their airways will be examined and areas of their lung will be washed. A small sample of cells will be taken.

This research study is an innovative school-based program for urban children with moderate to severe persistent or difficult-to-control asthma. The Telemedicine Enhanced Asthma Management-Uniting Providers (TEAM-UP) program enhances a school-based, primary care directed asthma program with specialist-supported care to ensure optimal guideline based treatment. This study is a full-scale randomized trial of TEAM-UP versus an enhanced care comparison group. Primary care physicians (PCP) of all enrolled children (n=360, 4-12 yrs.) will be prompted to initiate directly observed therapy (DOT) of preventive asthma medication through school and to make a specialist referral. For children in the TEAM-UP group, the specialist visits will be facilitated via telemedicine at school. The telemedicine specialist visit will be scheduled after 4 weeks of initiating DOT, in order to allow for accurate guideline-based assessments of medication and care needs once adherence with a daily controller medication is established. There will also be 2 telemedicine follow-up specialist visits to assess the child's response to treatment and make needed adjustments. The study will use the existing community infrastructure by implementing both telemedicine and DOT in school, and maintaining collaboration with PCPs. Blinded follow-ups will occur at 3-, 6-, 9- and 12-months after baseline, and the primary outcome is the comparison of symptom-free days (SFD) at each follow-up time point.

Asthma is now widely recognised to be a heterogeneous disease. The last two decades have seen the identification of a number of biological targets and development of various novel therapies. Despite this, asthma still represents a significant health and economic burden worldwide. Why some individuals should continue to suffer remains unclear. The Wessex Asthma Cohort of Difficult Asthma (WATCH) is an ongoing 'real-life', prospective study of patients in the University Hospital Southampton Foundation Trust (UHSFT) Difficult Asthma service. Research data capture is aligned with the extensive clinical characterisation required of a commissioned National Health Service (NHS) Specialist Centre for Severe Asthma. Data acquisition includes detailed clinical, health and disease-related questionnaires, anthropometry, allergy and lung function testing, radiological imaging (in a small subset) and collection of biological samples (blood, urine and sputum). Prospective data are captured in parallel to clinical follow up appointments, with data entered into a bespoke database. The pragmatic ongoing nature of the WATCH study allows comprehensive assessment of the real world clinical spectrum seen in a Specialist Asthma Centre and allows a longitudinal perspective of deeply phenotyped patients. It is anticipated that the WATCH cohort would act as a vehicle for potential collaborative asthma studies and will build upon our understanding of mechanisms underlying difficult asthma.
