Hulsey A, Cekola P, Henrikson A, Reichert H, Cohen SS, Torres KA. 2022. Growth and tolerance with an amino acid based enteral formula: A two-year retrospective study from a children’s rehabilitation hospital. J Clin Nutr Dietet 8(8):181.
Background: This study aimed to identify characteristics of a medically complex pediatric population that was fed an amino acid-based formula containing Medium-Chain Triglycerides (AA-MCT).
Methods: We examined calorie/protein prescription and intake, formula tolerance, concomitant use of Gastrointestinal (GI) medications, and growth (weight, height, Body Mass Index (BMI) z-scores). We reviewed medical records of children from a Hospital Rehabilitation Center, identifying those with a history of a tube-fed formula switch to the AA-MCT (n=23). We recorded demographic data (age, sex, diagnosis) and compiled outcomes data (formula intake, tolerance, GI medications, growth) at key time points over two years (pre-switch, at switch and post-switch).
Results: At AA-MCT initiation, mean age was 7.5 years and 48% of children had evidence of GI dysfunction. Atopic dermatitis and food allergies were present in 22%, others had genetic or metabolic disorders with severe GI impairment. Following switch to AA-MCT, mean calorie and protein intake increased, weight and height for age measures, and BMI z-scores were within expected ranges for most children. A reduction in GI medications was observed for some after the switch.
Conclusions: Children with medical complexity switched to AA-MCT formula demonstrated growth. Formula was well tolerated, as shown by increased intake of formula, appropriate growth for age and BMI z-scores up to 1 year post-switch.
