N2U -Part 3: EoE, IBD, and Cystic Fibrosis

2015 N2U Syllabus & Presentations

EoE Dietary Pointers (Syllabus pg 83-94): Sally Schwartz, Valeria Cohran

  • Even with SFED, elemental supplements helpful
  • Drink elemental beverages from covered glass with straw (improves palatability)
  • Cross-contamination –big issue
  • Label reading critical

IBD EEN Pointers (Syllabus pg 95-102): Rebecca Pipkorn, Justine Turner

  • Polymeric formulas –most palatable and least expensive. Oral EEN is used costly/not covered
  • EEN particularly helpful with microperforation/flare-up presentation and with infections (eg. TB)
  • EEN induces mucosal healing and improved symptoms


  • Levin et al. Inflamm Bowel Dis. 2014;20:278-285.
  • Johnson et al. Gut 2006;55:356-361.
  • Sigall-Boneh et al. Inflamm Bowel Dis. 2014;20:1353-1360.
  • Wilschanski et al. Gut 1996;38543–548.
  • Critich et al. J Pediatr Gastroenterol Nutr. 2012;54: 298–305. NASPGHAN Guidelines


  • Enteral therapy offers an alternative to steroids in patients with CD
  • Has potential to improve growth and IBD symptoms
  • Avoids the side effects of steroids
  • Need further research:
  1. – Unclear of the mechanism
  2. – Unclear of the best protocol
  3. – No standard protocol for reintroduction of food

Cystic Fibrosis (Syllabus pg 34-50) Justine Turner

Case in point: 10 yo with CF and poor growth, hx/o DIOS, poor intake, and distention.  Family had refused tube feedings previously.

Key point: Long-term survival is linked to nutritional status

  • Zemel et al. J Pediatr. 2000; 137(3):374-380.
  • Stallings et al. J Am Diet Assoc. 2008; 108(5):832-839.
  • McPhail et al. J Pediatr. 2008; 153(6):752-757.
  • Sharma et al. Thorax 2001; 56:746-750.

Other Caveats:

  • Intervene early
  • Breast milk (often with supplements) is optimal for infants
  • Poor oral intake àcould need periactin and/or supplemental feeds
  • Discussion re: pros/cons of Gtubes (pg 47 in syllabus)
  • Psychology support

Nutrition Goals

  • – Normal growth and optimal nutritional status
  • – Ages 0-2 year: Weight for length >50th percentile
  • – Ages 2-20 year: BMI percentile at or above 50th percentile
  • – BMI for males:23
  • – BMI for females: 22

Nutritional assessment at every visit & review:

  • – Weight, length/height, weight for length, BMI, head circumference in infants
  • – Nutritional education & dietary counseling
  • – Review PERT
  • – Review need for micronutrient supplementation: fat soluble vitamins (A, D, E, K), Ca, Fe, Zn, Na (salt), essential fatty acids

PERT (Pancreatic enzyme replacement therapy):

  • Infants 2000-4000 U lipase with 120 mL breast milk or formula– Mouth care for infants (and breast feeding mother)
  • Children 500-2500 U lipase/kg per meal (≤10000 U/kg/day or ≤ 4000 U/g fat/day); half meal dose with snacks
  • Ideally taken with meals and orally
  • Microspheres preferred formulation
  • Acid blockade (used to optimize enzyme activity)
  • Gold standard to assess adequacy is 72h fecal fat collection

Cystic Fibrosis Related Diabetes

  • Rare before 10 years of age
  • Increases mortality risk 6-fold
  • Weight loss and pulmonary decline begin 2-4 years prior to
  • diagnosis of CFRD
