Energy balance in cystic fibrosis when stable and during a respiratory exacerbation.

Background And Aims: Undernutrition is common in young adult patients with cystic fibrosis (CF) and implies an imbalance between energy intake and total energy expenditure (TEE). The aim of this study was to measure energy intake and TEE expenditure in a group of patients when they were clinically stable at home and during an exacerbation of respiratory symptoms when they were in hospital receiving intravenous antibiotics.

Methods: Eleven patients aged between 15 and 40 years with moderate respiratory disease, mean FEV(1) 51.
