Hyperferritinaemia and iron overload in Asian patients: lessons from an Australian tertiary centre experience.

Iron overload is described in Asian patients but presents with a different phenotype and genotype compared to Caucasian patients. We retrospectively identified 64 Asian patients and compared them to 64 matched non-Asian patients with at least one episode of serum ferritin >500 μg/L. Of the Asian patients, one (1.6%) had proven iron overload, while other common causes of hyperferritinaemia included recent blood transfusion (47%), acute infection (11%) and haematological malignancy (8%). A greater proportion of non-Asian patients had hyperferritinaemia secondary to high alcohol intake. Iron overload is rare in Asians and unexplained hyperferritinaemia in Asian patients is more likely to be due to other factors.
