Treatment of Hereditary Hemochromatosis in Juvenile Haemochromatosis or Severe Haemochromatosis with Life-Threatening Cardiac Iron Overload
Clinical Scenario
This protocol addresses hereditary hemochromatosis in two high-severity presentations: juvenile haemochromatosis, and severe haemochromatosis complicated by life-threatening cardiac iron overload.
Conditions
Juvenile haemochromatosis and severe haemochromatosis with cardiac iron overload represent situations where the urgency and extent of iron accumulation place particular demands on iron-removal strategies.
In the presence of severe clinical manifestations, a combined or alternative chelating approach is generally required during the iron-unloading phase.
Treatment Approach (partial)
Management in this setting centres on chelation therapy — which may be used in combination — with tailored alternatives available for patients who are unable to tolerate standard phlebotomy-based approaches.
Full regimen details, agent selection, sequencing, and clinical decision criteria are available in the complete protocol.

- In juvenile haemochromatosis, where chelation is typically begun in life-threatening cardiac iron overload, combination chelation therapy with oral DFP and intravenous DFO has been described in several case reports.
- In the presence of severe clinical manifestations, a combined or alternative chelating therapy is generally required in the unloading phase.
- In patients with advanced disease who poorly tolerate classical phlebotomies (e.g. because of low baseline haemoglobin or hemodynamically unstable because of cardiac impairment), personalised (mini)-phlebotomies plus subcutaneous infusion of deferoxamine (DFO) could be considered.
