[Iron in bone marrow].

J Oertel

    Folia Haematologica (Leipzig, Germany : 1928)
    |January 1, 1982
    PubMed
    Summary

    Assessing bone marrow iron stores via the Berlin blue stain is crucial for diagnosing iron deficiency anemia, even with normal serum iron levels. This method differentiates iron deficiency from other anemias and aids in identifying risks for leukemia.

    Area of Science:

    • Hematology
    • Iron Metabolism
    • Cell Biology

    Context:

    • Non-hemoglobin iron in bone marrow is primarily stored in the reticulum and as ferritin and hemosiderin.
    • Erythroblasts, or developing red blood cells, take up iron from plasma transferrin, regulated by erythropoietin.
    • Iron within erythroblasts is mainly used for hemoglobin synthesis, with a small portion stored as ferritin.

    Purpose:

    • To highlight the diagnostic significance of bone marrow iron staining for iron deficiency anemia.
    • To differentiate iron deficiency anemia from other conditions like sideropenic anemia with reticuloendothelial siderosis.
    • To underscore the importance of bone marrow iron assessment in diagnosing sideroblastic anemias and identifying associated risks.

    Summary:

    • The absence of stainable iron in the bone marrow reticulum is a reliable indicator of iron deficiency.
    • This diagnostic approach is effective even when serum iron and total iron-binding capacity are within normal ranges and erythrocytes show no hypochromia.
    • Bone marrow iron evaluation is essential for distinguishing iron deficiency anemia from sideropenic anemia and for diagnosing sideroblastic anemias.

    Impact:

    • Enables accurate diagnosis of iron deficiency anemia in complex cases, improving patient management.
    • Facilitates differential diagnosis of various anemia types, leading to more targeted treatments.
    • Contributes to identifying patients with abnormal sideroblasts, who have an increased risk of developing acute leukemia.
