[Iron deficiency anemia caused by occult intestinal bleeding due to milk allergy (author's transl)]

With the passive hemagglutination method the authors proved antibodies against milkprotein fractions in three of nine patients with hypochrome anemia aged 7, 12 and 17 months. In these children the X-ray examination showed an intestinal allergy, presumably the reason for occult intestinal bleeding which inturn caused hypochrome anemia. After milk was eliminated from the diet iron therapy restored a normal haemoglobin content. Iron therapy alone only improved the anemia, since continuing intestinal bleeding prevented fullrecovery.
