Summary

This trial will use 3D imaging and RNA sequencing to study why obese asthmatics have more severe disease, in hopes of finding better ways to treat it.

Who is the study for?
This trial is for adults aged 18-65 with asthma and a BMI ≥30 kg/m2, who have been on stable asthma medication for at least 3 months. Non-smokers or those who haven't smoked in the last 3 months are eligible. Participants must be able to perform spirometry tests and give informed consent. Pregnant women, individuals with significant illnesses like heart disease or uncontrolled diabetes, or those unable to complete study assessments are excluded.
What is being tested?
The trial is studying how obesity affects severe asthma by using advanced imaging called Hyperpolarized 129XeMRI and single cell RNA sequencing. It aims to understand airway remodeling and fibrosis in obese asthmatics compared to lean ones, potentially leading to better treatments.
What are the potential side effects?
While not explicitly listed in the provided information, potential side effects may include discomfort from lying still during MRI scans, anxiety due to claustrophobia inside the MRI machine, allergic reactions if contrast agents are used, and minor bruising from blood draws.
