Resting Energy Expenditure in Patients With Cystic Fibrosis: A Pilot Study

Not Applicable
Terminated
Conditions
Cystic Fibrosis
Interventions
Other: Daily calorie target based on resting energy expenditure
Registration Number
NCT03699982
Lead Sponsor
CAMC Health System
Brief Summary

Cystic fibrosis is an inherited disorder that causes severe damage to the lungs, digestive system, and other organs in the body. Individuals with cystic fibrosis often have poor weight gain and growth that can negatively impact health further by worsening lung function. Additionally, persons with the disease typically need more than the usual calories on a daily basis.

Most institutions estimate these patients' caloric needs using weight, age, and sex based mathematical formulae. However, numerous studies show that use of these formulae often yields inaccurate caloric values. Use of indirect calorimetry may give more accurate estimates of caloric needs in patients with cystic fibrosis.

The aim of our study is to assess the accuracy of caloric estimates generated using one such widely used mathematical formula, the Harris-Benedict equation, and to compare this calorie value with that obtained from indirect calorimetry testing in pediatric and adult patients with cystic fibrosis.

Study investigators will use the newly calculated caloric requirements in dietary counseling. Changes in weight and lung function after 3 months will be compared to participants' historical changes.

Primary Outcome Measures
NameTimeMethod
Resting energy expenditure estimation1 hour

Resting energy expenditure will be obtained using indirect calorimetry and the Harris-Benedict Equation.

Morphological variable changes3 months

Weight/height/BMI changes after 3 months of intervention and historical weight/height/BMI changes occurring during the 12 preceding months (reported as 3 month means).

Changes in pulmonary function status3 months

Changes in pulmonary function status, including FEV1%, after 3 months of intervention and historical pulmonary function status changes occurring during the 12 preceding months (reported as 3 month means).
