Plain English Summary
Background and study aims
People with Crohn's disease (a long-term condition causing inflammation of the lining of the digestive system) may experience a number of nutritional deficiencies even at times when their disease is not active. This study aims to look at the feasibility of carrying out a study to compare dietary counselling to standard written information to manage under-nutrition in people with Crohn's disease.
Who can participate?
Patients aged 18-65 with Crohn's disease in its inactive state attending outpatient appointments at Guy's and St Thomas' NHS Trust.
What the study involve?
Participants are randomly allocated to one of two groups. Both groups receive standard care in the form of written dietary information increasing portion size, meal frequency, food choice, nutrient density and food fortification. One group also receives dietary counselling tailored to provide an additional 600 kcal/d for a period of two months. At the end of the study, interviews are conducted to measure participant acceptability.
What are the possible benefits and risks of participating?
The participants may view the opportunity to receive well-established dietary counselling as a benefit of the study. The main disadvantages are the burden of participating in a study, the need to make dietary changes and the need to visit the research centre to carry out measurements on two occasions.
Where is the study run from?
Guy's and St Thomas' NHS Trust (UK)
When is the study starting and how long is it expected to run for?
February 2014 to May 2014
Who is funding the study?
King's College London (UK)

Detecting and managing undernutrition in adults with inactive Crohn's Disease: feasibility randomised comparative trial of oral nutritional support
The feasibility study will allow methodology, study design and outcome measures to be tested and a key outcome will be to measure patients' perceptions of the interventions, design and outcomes. This will provide essential information to inform the design of an adequately powered multicentre trial of oral nutritional support.

Nutritional support for inactive Crohn's disease
Participants will be randomised to two groups:
1. Intervention group: Receives standard care in the form of written information. In addition, they will receive dietary counselling individually tailored to increase dietary intake by 600 kcal/day over a period of two months.
2. Comparison group: Standard care only
Primary outcome measure
1. Recruitment rate, retention, attrition and feasibility
2. Eligibility criteria including screening for under-nutrition, study design and methodology
3. Qualitative interviews on experience of participation
Measured by Interview Acceptability Interview at at baseline and two months
Secondary outcome measures
1. Nutritional outcome measures (measured by anthropometry and food record charts)
2. Clinical Outcomes (markers of disease activity and a Stool and Symptom Diary)
3. Patient centred outcome measures (measured by questionnaires)
All completed at baseline and after two months
Overall trial start date
Overall trial end date
Reason abandoned (if study stopped)
Participant inclusion criteria

2. Diagnosis of Crohn's disease for duration of at least 6 months confirmed by standard clinical, histological and radiological criteria
3. Crohn's disease in remission as defined by Harvey Bradshaw score of < 5
4. Stable medications (see exclusion criteria), no recent surgery (see exclusion criteria) and stable symptoms for at least 2 months
5. BMI < 20 kg/m2
6. A willingness to participate
7. Individuals able to give informed consent
Target number of participants
24 participants. Each group will aim to recruit 12 participants.

9. Other concomitant serious comorbidity e.g. significant hepatic, renal, endocrine, respiratory, neurological or cardiovascular disease
10. Pregnancy or lactation
11. Taking any medications with the potential to influence gastrointestinal symptoms unless taking a long-term stable dose that is unlikely to change or stop during the trial
12. Currently receiving oral nutritional supplements, enteral or parenteral nutrition, or having received dietary counselling or oral nutritional supplements, enteral or parenteral nutrition, in the previous 3 months prior to study commencement
