An electrophoretically fast-moving hemoglobin variant was found in a 2-yr-old boy who was referred for evaluation with findings of iron deficiency anemia. The anemia was corrected, and no hematologic abnormality remained after treatment with iron. Oxygen affinity of the blood was normal, and no evidence was found of instability of the variant hemoglobin. Structural studies demonstrated a substitution of aspartic acid for alanine at beta76 (E20). This change did not appear to cause any functional disruption of the hemoglobin in this patient, as would be predicted by the position of the affected animo acid residue on the surface of the molecule.

Lactate, pyruvate, and alanine levels were investigated in patients with iron deficiency anemia and other types of anemia. The study was carried out on 36 children between 2 and 16 years of age. The study group was divided into three groups, each comprised of 12 children. It was shown that the anemic children have lower PO2, higher PCO2 and higher levels of lactate, pyruvate, and alanine than the control group (p less than 0.05). There was a negative linear correlation between lactate levels and hemoglobin values (r = -0.6213; p less than 0.05), but no correlation between hemoglobin and the alanine and pyruvate levels. Levels of lactate, pyruvate and alanine were similar in the iron deficiency and the other anemia groups. In conclusion, iron has no direct effect on the levels of lactate, pyruvate, and alanine, but the hypoxemia caused by anemia could be responsible for the higher levels of the lactate, pyruvate, and alanine. In cases with high levels of lactate, pyruvate, and alanine, anemia has to be considered in the differential diagnosis of hyperlactatemia.

Purpose: One of the most nutritional disorders around the world is iron deficiency. A novel iron compound was synthesized by chelating ferrous ions with alanine for prevention and treatment of iron deficiency anemia. Methods: The newly synthesized compound was characterized both qualitatively and quantitatively by Fourier Transform Infrared (FT-IR) spectroscopy. The bioavailability of newly synthesized iron micronutrient was evaluated in four groups of Wistar rats. The group I was a negative control group and the other three groups received three different iron formulations. After 14 days, the blood samples were taken and analyzed accordingly. Results: Calculations showed that more than 91.8% of iron was incorporated in the chelate formulation. In vivo studies showed that serum iron, total iron binding capacity and hemoglobin concentrations were significantly increased in group IV, which received ferrous bis alanine chelate compared with the negative control group (p<0.05) and also group II, which received ferrous sulfate.7H2O (p<0.05). It indicates that the new formulation considerably improves the blood iron status compared with the conventional iron compounds. There were no significant differences (p<0.05) in the serum iron between group IV and group III, which received ferrous bis glycine. Conclusion: The results showed better bioavailability of ferrous bis alanine as a new micronutrient for treatment of iron deficiency anemia in comparison with ferrous sulfate. Ferrous bis alanine could be considered as a suitable supplement for prevention and treatment of iron deficiency anemia.
