Rademikibart Add-on Treatment of an Acute Asthma Exacerbation (Seabreeze STAT Asthma)

This is a Phase 2, randomized, multicenter study in adult and adolescent participants with asthma and type 2 inflammation

Children's Health, Respiratory Inflammation and Short-term Air Pollution

The goal of this study is to see if physical activity in high air pollution is worse than rest in high air pollution.

ASMact: Study on Management of Bronchial Asthma

Standardization According to GINA 2025 Recommendations for the Treatment, Management, and Follow-up of Acute Asthma Attacks: Observational, Multicenter Cohort Study.

45th Multicenter Airway Research Collaboration

The study is a randomized controlled trial on the effect of emergency department initiation of Airsupra on acute asthma "recurrence" at 3 months and other related outcomes (acute asthma relapse, asthma control).

Creating A Risk Assessment Tool for Thunderstorm Asthma: the CARISTA Study

Thunderstorm asthma is a recurring public health emergency in South-Eastern Australia which occurs in springtime. The major identified risk factors for thunderstorm asthma is hay fever and allergy to ryegrass pollen. The goal of the CARISTA study is to identify the risk of springtime allergic and thunderstorm asthma in allergic adults living in South-Eastern Australia. To do this the investigators will recruit 530 people who have hay fever and test them for allergy to ryegrass pollen and undertake simple lung function testing. The investigators will ask study participants to complete a customised symptom tracker over the springtime pollen season for 2 consecutive years. The outcome the investigators are looking for is an asthma exacerbation or worsening asthma symptoms. This study will enable the investigators to identify indicators (biomarkers) of severe and moderate asthma exacerbations in order to identify those at risk of thunderstorm and seasonal asthma so protective treatments and strategies can be advised.

Nebulized Ketamine Plus Standard Care vs. Standard Care Alone in Moderate to Severe Asthma Exacerbations

The goal of this clinical trial is to learn if nebulized ketamine helps treat moderate to severe asthma attacks in adults in the emergency department. It will also learn about the safety of ketamine when inhaled through a nebulizer. The main questions it aims to answer are: * Does nebulized ketamine improve breathing more than standard treatment alone? * What side effects, if any, do participants experience after receiving nebulized ketamine? Researchers will compare nebulized ketamine to a placebo (a saltwater mist with no medication) to see how well it works and how safe it is. Participants will: * Receive either nebulized ketamine or a placebo mist, along with standard asthma treatment * Have their breathing checked before and after treatment using a peak flow meter * Be monitored for 60 minutes and have their symptoms, vital signs, and any side effects recorded

Remote Patient Monitoring Solution for Chronic Respiratory Disease Management

Aim: To evaluate the use of AeviceMD Monitoring System (AeviceMD) asthma in reducing acute exacerbation. Methodology: Using a randomized controlled trial design, this project aims evaluate the effectiveness of AeviceMD in improving patients' outcomes in terms of reducing exacerbation, healthcare utilization, improving quality of life, self-efficacy, and cost effectiveness. Paediatric patients above age 7 and adults will be recruited. The data follow-up period is 3 months. It will also evaluate the usability of the device from both patients' and clinicians' perspective. 180 patients (124 adults, 56 pediatrics) and 120 clinicians will be recruited. Importance of study: This study will evaluate if the AeviceMD can help improve disease management and reduce recurrence of asthma exacerbation. Potential benefits and risk: AeviceMD allows for remote monitoring and tracking of patients' lung sounds, which could be used by patients to monitor their lung condition and prevent an episode of exacerbation or worsening exacerbations culminating in an admission which who further utilize already limited healthcare resources. An exacerbation is an episode of severe shortness of breath, cough, and chest tightening which warrants a visit to a healthcare institution. Through self-monitoring, patients can be empowered to self-manage their asthma, with aid of the asthma action plan which is given to all patients with asthma. AeviceMD can also help provide clinicians with patients' objective lung data. In the primary care setting, care is also fragmented as patients are often followed-up by a different doctor or healthcare providers. Clinicians have no objective data to track patients, and is dependent on patients' self-report and possible recall bias. There is no expected risk with the use of the device.

Characterization of Natural Killer Cells in Severe Asthma Patients in Comparison With Control Subjects

Asthma is a common chronic bronchial disease affecting 300 million people worldwide. The disease can be severe when it is not managed properly or when it is not controlled by treatments. Asthma is characterized by bronchial inflammation, bronchial hyperreactivity and tissue remodeling. Symptoms include episodes of coughing, dyspnoea and wheezing in relation with bronchial obstruction. The evolution is marked by the occurrence of exacerbations (increase of symptoms), most often triggered by viral infections, mostly due to rhinoviruses. The treatment of asthma is based on inhaled corticosteroid therapy sometimes combined with other treatments that help control the majority of asthma. However, about 10% of patients suffer from persistent symptoms despite these treatments. Natural killer (NK) cells are important actors of the antiviral innate immune response and are present in high numbers in the lungs. However, their role in severe asthma and its virus-induced exacerbations is unknown. The purpose of this work is to characterize NK cells in severe asthma in order to identify molecules expressed differently from control subjects. The goal is to assess whether these molecules could be potential biomarkers of a severe asthma subtype, also known as the endotype, and/or be the molecular control for exacerbation. The advantage of identifying biomarkers for inflammatory diseases lies in their usefulness in establishing a correct diagnosis, monitoring the progress of the disease and the effectiveness of treatments. The secondary objectives are to characterize the activation of NK cells in response to in vitro rhinovirus infection of different types, in monoculture or in a model of interaction with a bronchial epithelium, and identify one or more molecules involved in the interaction between bronchial epithelial cells and NK cells.

Study on Acupuncture Treatment of Chronic Airway Diseases(Asthma and Chronic Obstructive Pulmonary Disease)

For patients in the acute phase of chronic airway diseases, on the basis of guideline-directed treatment, the experimental group was given acupuncture treatment, while the control group was given sham acupuncture treatment. The treatment lasted for one week, followed by a 13-week follow-up. For asthma and COPD, PEF and CAT were respectively used as the primary outcome measures to evaluate the clinical efficacy and safety of acupuncture. Based on the improvement of the primary outcome measures, the advantageous population was identified. The mechanism by which acupuncture reduces airway mucus hypersecretion was preliminarily explained.

Retrospective Study of Patients with Acute Presentation for Asthma to an Emergency Department in UK (RAPAE)

Study team will obtain a list of all patients who have been seen in A+E over the past 6 years with a discharge diagnosis of asthma. Their history will be reviewed from their A+E notes. Team will obtain weight and height from Electronic prescribing tool and will obtain compliance information and past medical history from participant's GP records. Team will use participant's postcode to word out socio economic status quintile using office of national statistics tool. The following information will be taken from hospital documentation and from GP records.
