General Medicine · Haematology: anaemia of chronic disease

Sample item

A patient with rheumatoid arthritis has MCV of 80 fL, serum iron low, TIBC low and ferritin of 400 ng/mL. What is the mechanism?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Hepcidin-mediated iron sequestration by inflammation

Inflammatory cytokines such as IL-6 raise hepcidin, which blocks ferroportin and traps iron in macrophages, giving low serum iron and TIBC with normal or high ferritin. Anaemia is usually normocytic to mildly microcytic. Treating the underlying disease improves it.

Option by option

  • A. Hepcidin-mediated iron sequestration by inflammation (correct)

    Correct. Hepcidin causes functional iron restriction.

  • B. Vitamin B12 deficiency

    B12 deficiency causes macrocytosis.

  • C. Chronic blood loss

    Blood loss would give low ferritin and high TIBC.

  • D. Defective globin synthesis

    Globin defects occur in thalassaemia.
