What this trial studies

Infants under one year with gastroesophageal reflux disease are assigned to a cow's-milk-protein-free diet, omeprazole treatment, or placebo, with symptoms and feeding/weight outcomes tracked during the treatment period. Inclusion requires at least three reflux episodes per day and presence of troublesome symptoms such as unexplained crying, poor weight gain, or back-arching. Exclusions include recent PPI use, diagnosed cow's milk protein allergy, certain congenital or metabolic conditions, and infants already on a cow's-milk-free diet. The trial compares symptom change, adverse events, and growth to see which approach reduces troublesome reflux while minimizing side effects.

Who should consider this trial

Good fit: Infants aged 1 to 11 months with diagnosed gastroesophageal reflux disease who have at least three reflux episodes per day and troublesome symptoms are ideal candidates.

Not a fit: Infants with known cow's milk protein allergy, recent PPI treatment, major congenital or metabolic disorders, or those already on a cow's-milk-free diet may not benefit from enrollment.

Why it matters

Potential benefit: If successful, this could reduce unnecessary PPI use and offer a safer dietary option that lowers symptoms and side effects in infants with GERD.

How similar studies have performed: Previous randomized studies in infants under one year are few and generally have not shown clear symptom benefit from PPIs, and recommendations for cow's-milk-protein-free diets are based on weak evidence.
