EASL International Consensus Conference on Haemochromatosis: Part II. Expert Document☆☆☆
The precise frequency of the different iron overload states due to haemochromatosis (HC) is unknown and need to be addressed in population studies . The appropriate terminology for different iron overload states along the continuum is given below. The expert panel considers it both appropriate and feasible to define an over-accumulation state distinct from haemochromatosis. “Excess body iron storage” (iron overload) [haemosiderosis=iron staining in tissues] may be: i) Minimal: ∼1.5g (hepatic iron concentration, HIC, >30 μM/g) (?pathological significance: e.g. porphyria cutanea tarda (PCT); ii) Modest: 2–5 g (HIC>100 μM/g; serum ferritin approx 500 μg/l) (seen in chronic liver disease, haemolytic disorders, PCT, etc.); iii) Severe: >5 g (HIC >200 μM/g; serum ferritin approx 750 μg/l).
