Study of Hepatic Glucose Production and De Novo Lipogenesis in Patients With Cystic Fibrosis
An observational study of Cystic Fibrosis, run by University of Utah at 1 site in United States.
Trial summary
OBJECTIVES: I. Determine the amount of hepatic glucose production derived from gluconeogenesis and glycogenolysis in the post-absorptive state in patients with cystic fibrosis. II. Determine de novo lipogenesis in relationship to resting energy expenditure in this patient population. Read more about this study

II. Determine de novo lipogenesis in relationship to resting energy expenditure in this patient population.
Read the detailed description
PROTOCOL OUTLINE:
Patients undergo an oral glucose tolerance test (OGTT) in which blood is drawn from an IV in the arm 6 times over 3 hours. After the first blood draw, patients receive a beverage containing sugar and write down everything they ate and drank during the 24 hours before study entry. Patients also undergo a dual energy x-ray absorptiometry (DEXA) scan over 15 minutes.
Within 2 weeks after the OGTT, patients keep a journal of everything they ate and drank over 3 days. Patients are fed a selected meal the following evening and receive saline fluids IV overnight. During the night, patients receive 2 doses of oral doubly labeled water. The next morning, patients receive [1,2-13C]acetate IV. A liquid mixed meal (Ensure Plus) is ingested hourly throughout the day. Patients also undergo hood indirect calorimetry over 30 minutes twice to measure resting energy expenditure. All urine is collected.

Questions about this trial
What is this clinical trial studying?
An observational study of Cystic Fibrosis, run by University of Utah at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Mar 2009. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Mar 2009; AzTrials last refreshed its copy on 8 Nov 2026.
