NCT04016194

Brief Summary

Retrospective cohort study using routinely collected annual data on lung clearance index (LCI) in combination with clinical data to predict survival in patients with Cystic Fibrosis. The primary study endpoint is the association of LCI with the compound outcome survival or lung transplantation in patients with CF.

Outcome Measures

Primary Outcomes (1)

  • Lung clearance index (LCI)

    Lung function outcome derived by MBW and the compound Outcomes mortality or lung transplantation

    Lung function is collected quarterly until outcome (death or lung transplantation) or end of Study (12/2005) is reached

Secondary Outcomes (7)

  • Functional residual capacity (FRC)

    Lung function is collected quarterly until outcome (death or lung transplantation) or end of Study (12/2005) is reached

  • Forced expired Volume in 1 second (FEV1)

    Lung function is collected quarterly until outcome (death or lung transplantation) or end of Study (12/2005) is reached

  • Body weight

    Characteristics are collected quarterly until outcome (death or lung transplantation) or end of Study (12/2005) is reached

  • Body length

    Characteristics are collected quarterly until outcome (death or lung transplantation) or end of Study (12/2005) is reached

  • Gender

    Characteristics are collected quarterly until outcome (death or lung transplantation) or end of Study (12/2005) is reached

  • +2 more secondary outcomes

Interventions

Lung function testingDIAGNOSTIC_TEST

Multiple-breath washout (MBW) is a safe, easy and sensitive lung function test using inert gases such as Nitrogen (N2) to assess efficiency of ventilation distribution. The latter can be estimated by the lung clearance index (LCI), an established study end-point in patients with CF

Also known as: Multiple-breath washout, MBW
