Gastrointestinal occult hemorrhage and gastroduodenitis in cow's milk protein intolerance.
We are reporting on four infants with cow's milk protein intolerance who presented with hypochromic anemia and occult gastrointestinal hemorrhage. Esophagogastroduodenoscopy revealed erosive gastritis or gastroduodenitis in all cases. Management with a cow's milk-free diet led to a favorable clinical and hematological outcome; the endoscopic inflammatory image disappeared after the cow's milk-free diet trial. Challenge with cow's milk led to gastrointestinal symptoms and to impaired D-xylose absorption. The data presented suggest that some patients with cow's milk intolerance may have gastroduodenitis resulting in occult gastrointestinal hemorrhage and hypochromic anemia.
