Evaluation of a free amino acid-based formula in infants with presumptive food protein-induced proctocolitis.

ABSTRACT:

Objective

Food protein-induced proctocolitis usually occurs early in life and is characterized by blood-streaked stools and pain during defecation in an otherwise healthy infant. While many infants with food protein-induced proctocolitis respond well to a casein hydrolysate formula, some require an amino acid-based formula. The objective of the study was to measure the change in physician-rated symptom score from enrollment to study completion in infants with presumptive food protein-induced proctocolitis fed with a specific amino acid-based formula.

Methods

In this study, infants ≤6 months of age diagnosed with presumptive food protein-induced proctocolitis received an amino acid-based formula for 42 days. Intake, stool patterns, weight, stool occult blood, and questionnaires assessing infant feeding and stool patterns and parental formula satisfaction were collected.

Results

The full analysis set included 43 infants. The mean age at enrollment was 59 ± 5 days. A significant improvement was observed from enrollment to exit in physician-rated symptom score (9.1 ± 0.5 to 4.8 ± 0.5, p < 0.0001), the number of infants with occult blood in stool, and weight-for-age Z-scores during the study. Parental satisfaction with the formula was high.

Conclusion

The results confirm that the amino acid-based formula studied is efficacious for managing symptoms of presumptive food protein-induced proctocolitis.
