Treatment of Hemochromatosis (Haemochromatosis)
Patients with hemochromatosis and evidence of iron overload should undergo therapeutic phlebotomy as first-line treatment, with weekly bloodletting of 400-500 mL during the induction phase until serum ferritin reaches 50 μg/L, followed by maintenance phlebotomy every 1-4 months to maintain ferritin between 50-100 μg/L. 1
Induction Phase Treatment
Weekly or fortnightly phlebotomy is the cornerstone of initial therapy: 1
- Remove 400-500 mL of blood per session, adjusted for body weight and patient tolerance 1
- Continue until serum ferritin reaches 50 μg/L (but not lower to avoid iron deficiency) 1
- Monitor hemoglobin before each session 1
- If hemoglobin drops below 12 g/dL, decrease phlebotomy frequency 1
- If hemoglobin falls below 11 g/dL, discontinue phlebotomy temporarily and reassess 1
Erythrocytapheresis represents an alternative to standard phlebotomy, particularly cost-effective during induction as it requires fewer interventions. 1
Maintenance Phase Treatment
After achieving iron depletion, lifelong maintenance therapy prevents iron re-accumulation: 1
- Target serum ferritin: 50-100 μg/L 1
- Phlebotomy frequency: every 1-4 months depending on individual iron accumulation rate 1
- Average ferritin rises approximately 100 μg/L per year without treatment 1
- Patients without significant organ damage can serve as regular blood donors during maintenance 1
Critical Monitoring Parameters
Serum ferritin and hemoglobin must be monitored at each phlebotomy session to prevent both under-treatment and iron deficiency: 1
- Check hemoglobin at every bloodletting session 1
- Monitor ferritin to ensure target achievement and avoid overtreatment 1
- Ferritin below 20 μg/L significantly increases dietary iron absorption, indicating excessive depletion 1
Assessment of Liver Disease and Complications
All patients require non-invasive fibrosis assessment at diagnosis to guide treatment intensity and surveillance: 1
- Transient elastography with liver stiffness <6.4 kPa rules out advanced fibrosis 1
- Patients with ferritin <1,000 μg/L, normal transaminases, and no hepatomegaly have very low risk of advanced fibrosis 1
- Patients with cirrhosis (METAVIR F4) require HCC screening with abdominal ultrasound every 6 months regardless of iron depletion status 1
- Patients with advanced fibrosis (METAVIR F3) should also undergo HCC screening every 6 months 1
Cardiac Evaluation
Patients with severe iron overload require cardiac assessment due to risk of cardiomyopathy and arrhythmias: 1
- Perform ECG and echocardiography in all patients with severe overload 1
- Cardiac MRI for myocardial iron quantification is mandatory in juvenile hemochromatosis 1
- Iron removal therapy can prevent, improve, or even reverse cardiac dysfunction 1
- Conventional cardiology treatment should be initiated for heart failure and arrhythmias 1
Dietary Modifications
Specific dietary restrictions enhance treatment efficacy and prevent iron re-accumulation: 2, 3
- Avoid all vitamin C supplements during treatment, as pharmacologic doses accelerate iron mobilization and increase risk of cardiac complications and sudden death 2
- Avoid iron supplements and iron-fortified foods entirely 2, 3
- Limit red meat consumption 3
- Restrict alcohol intake, particularly during iron depletion phase 3
- Dietary vitamin C from foods requires only moderation, not elimination 2
Management of Specific Complications
Arthropathy affects 45-57% of patients and requires symptomatic management as phlebotomy does not reverse joint damage: 3
- NSAIDs and analgesics for pain control 3
- Joint replacement surgery ultimately required for end-stage disease 3
- Arthropathy can progress despite optimal iron management 3
Endocrine manifestations require targeted evaluation: 1
- Assess for diabetes mellitus 1
- Measure sex hormone concentrations for reproductive/sexual dysfunction 1
- Evaluate thyroid, adrenal, and parathyroid function when clinically indicated 1
Special Populations: Pregnancy
Iron deficiency must be avoided in pregnant patients with hemochromatosis: 1
- Achieve ferritin >45 μg/L before conception 1
- In mild to moderate iron overload without advanced liver disease, phlebotomy can be paused during pregnancy 1
- Normal pregnancy corresponds to iron requirement of approximately 500 mg 1
- Management is determined by liver disease stage and extrahepatic manifestations 1
Prognostic Impact of Treatment
Morbidity and mortality are significantly reduced when treatment begins before development of cirrhosis and diabetes. 1
- Phlebotomy improves survival in clinical and cohort studies 1
- Treatment may improve fatigue, arthralgias, and liver function tests 1
- Regression of liver fibrosis and cirrhosis occurs in a subset of patients 1
- Conclusive data on quality of life, liver cancer risk reduction, and cardiovascular disease impact remains limited 1
Common Pitfalls to Avoid
- Never supplement with vitamin C during active treatment—this poses serious cardiac risk 2
- Avoid excessive iron depletion (ferritin <50 μg/L during maintenance) which increases iron absorption 1
- Do not neglect HCC surveillance in cirrhotic patients even after successful iron depletion 1
- Monitor vitamin B12 and folate in patients requiring frequent phlebotomies to prevent macrocytic anemia 4
