The objective of the study is to implement a new method of performing chest CT imaging in young children with cystic fibrosis at Packard Children's Hospital. This technique will be used to evaluate early lung disease comparing quantitative chest CT air trapping and airway measurements with lung function measurements in infants, toddlers, and young children with chronic lung disease.

Further study details as provided by Stanford University:

Primary Outcome Measures:
  • Quantitative Air Trapping, A2 & A3 [ Time Frame: Baseline & F/U ]
    Quantitative Chest CT Air Trapping by CT post-processing for Measure A2 & Measure A3 (% of segmented total lung)

  • Quantitative CT Airway Measurements (AWT/TAD, LD/TAD, Wall Area %, Lumen Area % [ Time Frame: Baseline & F/U ]
    Quantitative Chest CT airway measurements by CT Post-Processing. AWT/TAD = Airway Wall Thickness/Total Airway Diameter LD/TAD = Lumen Diameter/Total Airway Diameter Wall Area % = Wall Area/Total Airway Area (%)

Secondary Outcome Measures:
  • FEV 0.5 sec [ Time Frame: Baseline & F/U ]
    FEV 0.5sec = % predicted

  • FEF 85% [ Time Frame: Baseline & F/U ]
    FEF 85% (% predicted)

  • FEF25-75% [ Time Frame: Baseline & F/U ]
    FEF25-75% (% predicted)

Estimated Enrollment: 25
Study Start Date: September 2010
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)

Ages Eligible for Study:   2 Months to 5 Years   (Child)

Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Young children with cystic fibrosis at Packard Children's Hospital.

Inclusion Criteria:

  1. Infants and young children (age ~ 2/3 months to < 5 years)
  2. Diagnosed with cystic fibrosis with either 2 identified CFTR gene mutations, or a positive sweat chloride
  3. Informed consent by parent or legal guardian.
  4. Ability to comply with study visit procedures as judged by the investigator.

Exclusion Criteria:

  1. Acute wheezing and/or respiratory distress at either study visit.
  2. Acute intercurrent respiratory infection, defined as an increase in cough, wheezing, or respiratory rate with onset in 1 week preceding Study visit.
  3. Oxygen saturation < 90% on room air at study visit.
  4. Any medical condition that in the opinion of the investigator precludes subject participation.
