[Iron deficiency anemia caused by occult intestinal bleeding due to milk allergy (author's transl)]. / Eisenmangelanämie infolge okkulter Darmblutungen bei Milchallergie.

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.
