Additional Information

Official title Study of Total Energy Expenditure in Infants and Children With Moderate to Severe Cystic Fibrosis
Description PROTOCOL OUTLINE: Patients and healthy controls receive an oral dose of doubly labeled water following initial urine collection on day 1. Patients undergo additional urine collection at 4-6 hours following doubly labeled water consumption and then daily for 7 days. Additionally, at the beginning of the study, patients and healthy controls undergo respiratory calorimetry over approximately 45 minutes at rest, starting approximately 2-3 hours after the last meal consumption and last use of aerosol bronchodilators (if required).
