Energy Metabolism in Patients With Short Bowel Syndrome

December 2, 2014 updated by: Julio Sergio Marchini, University of Sao Paulo

Assessment of Energy Metabolism in Patients With Short Bowel Syndrome Using the Doubly Labeled Water Method

This study proposes to verify the total energy expenditure in patients with short bowel syndrome using the doubly labeled water method, as well as determining the rate of oxidation of nutrients, aiming to assist the management of nutritional therapy for these patients.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

The recruitment of volunteers with short bowel syndrome (SIC) will be done in the Hospital das Clinicas, Faculty of Medicine of Ribeirão Preto, University of São Paulo (HCFMRP / USP). These individuals will be paired with volunteers without short bowel syndrome, which will be selected at the clinics of the Hospital of the Faculty of Medicine of Ribeirão Preto, and will constitute the control group.

Description

Inclusion Criteria:

  • Short bowel syndrome: short bowel syndrome patients with gastrointestinal transit time less or equal 30 minutes.
  • Control group: patients with the same gender, presenting age and chronic diseases similar with volunteers from the group with short bowel syndrome.

Exclusion Criteria:

- Short bowel syndrome: time of bowel resection surgery less than 1 year.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Assessment of total energy expenditure using the doubly labeled water method
Time Frame: 14 days
After the determination of resting energy expenditure (REE), each volunteer will receive a dose of doubly labeled water (2H2 18O). A basal urine sample is collected before the intake dose and samples taken on days 1, 2, 3, 7, 12, 13, 14, thereafter. Urine samples will be analyzed by mass spectrometry (Hydra System, HIP 20-20, Europa Scientific, Cheshire, UK) in the Mass Spectrometry Laboratory of the Faculty of Medicine of Ribeirão Preto.
14 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Resting energy expenditure (REE) and body composition measurements by indirect calorimetry and electrical bioimpedance, respectively.
Time Frame: After 12 hours of overnight fasting
This study also aims to measure the REE by indirect calorimetry with a Quark (Cosmed, Italy) calorimeter and the body composition by Byodinamics 450 (Biodynamics Corp., United States).
After 12 hours of overnight fasting
Physical activity assessment
Time Frame: 14 days
An activity monitor (activPAL ®, Glasgow, UK) is used to determine physical activity. By registering the intensity and duration of each category of activities, the system adds the energy estimated to generate a value that reflects the total energy expenditure.
