The ferritin levels measured usually have a direct correlation with the total amount of iron stored in the body. However, ferritin levels may be artificially high in cases of anemia of chronic disease, where ferritin is elevated in its capacity as an inflammatory acute phase protein and not as a marker for iron overload. [citation needed]
Anemia of chronic disease (ACD) [1] [2] or anemia of chronic inflammation [3] is a form of anemia seen in chronic infection, chronic immune activation, and malignancy. These conditions all produce elevation of interleukin-6 , which stimulates hepcidin production and release from the liver.
The main role of transferrin is to deliver iron from absorption centers in the duodenum and white blood cell macrophages to all tissues. Transferrin plays a key role in areas where erythropoiesis and active cell division occur. [16] The receptor helps maintain iron homeostasis in the cells by controlling iron concentrations. [16]
Inflammatory cytokines stimulate the liver to produce the iron metabolism regulator protein hepcidin, that reduces available iron. If hepcidin levels increase because of non-bacterial sources of inflammation, like viral infection, cancer, auto-immune diseases or other chronic diseases, then the anemia of chronic disease may result. In this case ...
The physiological role of decreased synthesis of such proteins is generally to save amino acids for producing "positive" acute-phase proteins more efficiently. Theoretically, a decrease in transferrin could additionally be decreased by an upregulation of transferrin receptors , but the latter does not appear to change with inflammation.
However ferritin levels may be elevated due to a variety of other causes including obesity, infection, inflammation (as an acute phase protein), chronic alcohol intake, liver disease, kidney disease, and cancer. [7] [32] [33] In males and postmenopausal females, normal range of serum ferritin is between 12 and 300 ng/mL (670 pmol/L) .
However, inflammatory and neoplastic disorders can cause ferritin levels to increase – this may be seen in cases of hepatitis, leukemia, Hodgkin lymphoma, and gastrointestinal (GI) tract tumors. [4] The most sensitive and specific criterion for iron-deficient erythropoiesis is depleted iron stores in the bone marrow. However, in practice, a ...
Serum ferritin is a low cost, readily available, and minimally invasive method for assessing body iron stores. However, the major problem with using it as an indicator of hemosiderosis is that it can be elevated in a range of other medical conditions unrelated to iron levels including infection, inflammation, fever, liver disease, renal disease ...
