Brief summary

This study will compare the tolerability and efficacy of conventional formula Exclusive Enteral Nutrition (EEN) and whole-food blended smoothie EEN by enrolling a total of 60 participants with newly diagnosed pediatric Crohn's disease (CD). Participants will be provided either commercial formula or guided on the preparation of the home-blended smoothie. These participants will be given a specific recipe, blender, and be provided the food components to the smoothie. The study will total 8 weeks and will assess tolerance, clinical outcomes, stool microbiome, and quality of life.

Interventions

OTHERWhole-food based smoothie

The smoothies will be based upon the concept of reverse-engineering of exclusive enteral nutrition and provide 100% of calculated caloric needs for weeks 0-4. At week 4, select foods will be introduced to provide up to 20% of daily caloric needs.

OTHERFormula

Conventional formula (Boost, Ensure, Modulen) as per the direction of their primary Gastroenterology team to provide 100% of calculated caloric needs for weeks 0-4. At week 4, select foods will be introduced to provide up to 20% of daily caloric needs.

Inclusion criteria

* Age 8 -21 years old. * Diagnosis of Crohn's disease within 24 months * Elevation in objective inflammatory markers at enrollment: C-reactive protein (CRP), ESR, or fecal calprotectin * Active Crohn's disease, as defined by Pediatric Crohn's Disease Activity Index (PCDAI) ≥10. * Participant capable of giving informed consent, or if a minor the parent/guardian is capable of giving informed consent.

Exclusion criteria

* History of surgery for Crohn's disease. * Perianal disease as part of Crohn's disease phenotype. * Recent use of: * corticosteroids (within 4 weeks), * dose adjustment of immunomodulator (within 8 week) * azathioprine 4 weeks prior to study final visit (week 8) * start or adjust methotrexate 3 weeks prior to final study visit. * Prior use of biological medication * Prior treatment with EEN or other dietary therapy for Crohn's disease. * Prior treatment with antibiotics for Crohn's disease. * Known allergies to any of the food components in the smoothie. * Admission to hospital due to severity of Crohn's disease and associated symptoms. * Unwillingness to provide informed consent.

Design outcomes

Primary

MeasureTime frameDescription
Tolerance- Ability to remain on prescribed nutritional therapy4 and 8 weeksTolerance of therapy as measured by ability to continue prescribed nutritional therapy over 4-weeks and 8-weeks without deviation from protocol. Participants will meet with a study dietitian at week 2, week4, and week 8. Dietitians will evaluate caloric needs, specific deficits, and dietary limitations.

Secondary

MeasureTime frameDescription
Fecal Calprotectin reduction from baseline4 and 8 weeksFecal calprotectin (FCP) level \<250 μg/gram
Pediatric Crohn's Disease Activity Index (PCDAI) reduction from baseline4 and 8 weeksPediatric Crohn's Disease Activity Index (PCDAI) score \<10 (clinical remission). PCDAI will be calculated at each visit. The total score is calculated from assessments in 11 sections. Minimum score 0. Maximum score 100. A lower score is better. History (recall 1 week) * Abdominal pain * Stools * Patient functioning * General well-being Physical Examination * Weight * Height * Abdomen * Peri-rectal disease * Extra-intestinal manifestations Laboratory * Hematocrit (%) * Erythrocyte sedimentation rate (ESR) (mm/hr) * Albumin (g/L)
