Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are individuals who have undergone bilateral lung transplantation at Zurich University Hospital.

Probably not a fit

Patients who have undergone retransplantation will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to detect chronic rejection, known as bronchiolitis obliterans syndrome (BOS), in lung transplant recipients through a noninvasive method called Multiple Breath Washout (MBW) tests. By measuring lung clearance index (LCI) three months post-transplant, the study seeks to identify early signs of BOS, which is a leading cause of mortality after the first year of transplantation. Early detection may allow for timely treatment adjustments to improve patient outcomes. Approximately 90 participants from Zurich University Hospital will be involved in this assessment.

Why it matters

Potential benefit: If successful, this approach could lead to earlier interventions that significantly improve survival rates for lung transplant recipients.

How similar studies have gone: Other studies have shown promise in using noninvasive methods for early detection of transplant dysfunction, making this approach both relevant and potentially impactful.
