|Associations between hyperferritinemia and autoimmune diseases|
|Hyperferritinemia (%)||Described associations between hyperferritinemia and autoimmune diseases|
|RA||4% ||✓ High concentrations of ferritin are found in synovial fluid and synovial cells of RA patients .|
|✓ Significant correlations described between serum ferritin levels and disease activity by DAS28 score in RA patients .|
|MS||8% [6,7]||✓ Loss of ferritin binding is involved in, or is a consequence of, demyelination associated with MS .|
|✓ Ferritin levels are significantly elevated in the serum and the cerebrospinal fluid only in chronic progressive active patients .|
|✓ Hyperferritinemia is associated with male gender and a more progressive type of MS (that is, relapsing-progressive), whereas an inverse association was noted between the milder form of disease (relapsing-remitting) .|
|SLE||23% ||✓ Serum levels of ferritin during the more active stage of SLE exceeded those of RA patients and patients at less active stages of SLE .|
|✓ Hyperferritinemia is associated with serositis and hematological manifestation .|
|✓ ECLAM score is significantly higher in patients with hyperferritinemia .|
|✓ Hyperferritinemia is associated with thrombocytopenia, lupus anticoagulant and anticardiolipin antibodies in SLE patients with active disease .|
|APS||Primary APS 8%||✓ In patients with APS syndrome, hyperferritinemia is associated with the presence of venous thrombotic events, cardiac, neurological and hematological manifestations .|
|Secondary APS 9% |
