The purpose of this research is to determine how a person's lungs will uptake [18F]fluorodeoxyglucose (FDG), as measured with positron emission tomography (PET) scanning in young cystic fibrosis patients.

Procedure: [18F]FDG PET/CT
FDA-approved Investigational New Drug (IND) to use [18F]FDG in CF patients under the age of 18 years (PI: Robert Mach, MD, IND # 76079). Imaging data will be acquired with a Siemens Biograph 40PET/CT Tomograph. Research participants will be positioned supine in the scanner and a scout CT topograph obtained.

Detailed Description:
Our recent study in CF adults, supplemented by recent pre-clinical and clinical studies by our group suggests that FDG-PET imaging may be a valuable quantitative biomarker of lung inflammation. The proposed study would validate our earlier findings, but in a younger patient population. The implications of such a test could be highly significant for both the testing of promising new anti-inflammatory agents and for patient management decisions. To capitalize on this exciting opportunity, the critical next step is to show that we can identify a cohort of young CF patients with both stable lung function and normal (or near normal) FDG-PET imaging studies. Similar patients, then, would become the subjects for a future prospective cohort study to determine if FDG-PET imaging can in fact serve as a predictor of future changes in lung function.
Ages Eligible for Study: | 12 Years to 21 Years |
Genders Eligible for Study: | Both |
Accepts Healthy Volunteers: | No |
Sampling Method: | Probability Sample |
Our Pediatric Cystic Fibrosis Clinic currently has 124 patients between the ages of 12 and 21 years. We will need to recruit patients from this clinic population, plus new patients that enter the clinic over the 2 to 3 year period.
Inclusion Criteria:
- Confirmed diagnosis of cystic fibrosis
- Age 12 to 21 years old, of either gender, any race or ethnicity
- Stable recent pulmonary status (defined as no new pulmonary symptoms, new antibiotic use, or hospitalization for pulmonary symptoms for at least 1 month).
- We will permit patients treated with the macrolide antibiotic, azithromycin, to participate in this study. Azithromycin has recently become a virtual standard of care in CF [36], based on small but reproducible improvements in pulmonary function over 4 months of treatment with this drug. The mechanism of benefit is uncertain, but an anti-inflammatory effect has been suggested [36]. The high prevalence of use means that a study without azithromycin would likely require a wash-out period, without data about the appropriate duration for such a wash-out, or whether inflammatory markers would reverse during that time.
Exclusion Criteria:
- Failure to obtain informed consent
- Positive pregnancy test or lactation
- Currently enrolled in another study involving radioisotopes or an investigational drug
- Recent (within 30 days of screening) hospitalization for any reason
- New antibiotic use (within 30 days of screening).
- Patient incapable of lying still and supine within the PET/CT scanner for 90 minutes.
- Patient incapable of completing other testing procedures (e.g., PFT, induced sputum)
- Patient with serum glucose greater than 150 mg/dl at time of PET imaging study
- Patient incapable of fasting for 4 to 6 hrs prior to PET imaging study
