From the Guidelines
Therapeutic phlebotomy is the primary treatment for managing high hemoglobin levels in patients with hemochromatosis, with the goal of reducing iron overload and preventing organ damage. The treatment involves removing 450-500 mL of blood weekly or biweekly until ferritin levels reach 50-100 ng/mL and transferrin saturation falls below 50% 1. This intensive phase typically lasts 2-3 months, after which maintenance phlebotomy is performed every 2-4 months based on ferritin levels.
Some key points to consider in the management of high hemoglobin levels in hemochromatosis include:
- Patients should avoid iron supplements and vitamin C with meals, as vitamin C enhances iron absorption 1.
- Limit consumption of red meat and alcohol, as they can contribute to iron accumulation and liver damage 1.
- Chelation therapy with medications like deferasirox (Exjade, 20-40 mg/kg/day) or deferoxamine (Desferal, 20-40 mg/kg/day subcutaneously) may be used for patients who cannot tolerate phlebotomy 1.
- Regular monitoring of hemoglobin, ferritin, and transferrin saturation is essential to guide treatment frequency 1.
- Adequate hydration before and after phlebotomy helps prevent hypotension, and patients should increase fluid intake and consume a light meal beforehand 1.
The most recent and highest quality study on this topic is the 2022 EASL clinical practice guidelines on haemochromatosis, which provides a comprehensive overview of the diagnosis, treatment, and management of hemochromatosis 1. These guidelines emphasize the importance of early diagnosis and treatment to prevent complications and improve patient outcomes.
In terms of specific treatment targets, the guidelines recommend aiming for a serum ferritin level of 50-100 ng/mL during the maintenance phase, with adjustments made based on individual patient needs and response to treatment 1. Overall, therapeutic phlebotomy is a safe and effective treatment for managing high hemoglobin levels in patients with hemochromatosis, and should be tailored to each patient's individual needs and circumstances.

From the Research
Management of High Hemoglobin Levels in Hemochromatosis
- High hemoglobin levels in patients with hemochromatosis can be managed through various treatments, including phlebotomy and iron chelation therapy 2, 3, 4, 5.
- Phlebotomy is the mainstay therapy for hemochromatosis, which involves the removal of blood from the body to reduce iron levels 2, 5.
- Iron chelation therapy, such as deferasirox, can be used as an alternative to phlebotomy in some patients, particularly those who are intolerant or have poor venous access 3, 4.
- Deferasirox has been shown to be effective in reducing iron burden in patients with hereditary hemochromatosis, with significant decreases in serum ferritin and transferrin saturation levels 3, 4.
Diagnosis and Classification of Hemochromatosis
- Hemochromatosis is a genetically heterogeneous disorder characterized by uncontrolled intestinal iron absorption, leading to progressive iron overload 6.
- The diagnosis of hemochromatosis involves clinical assessment, blood tests, imaging, and in some cases, liver biopsy 5.
- A new classification system for hemochromatosis has been proposed, which emphasizes clinical issues and molecular complexity, rather than molecular subtype criteria alone 6.
Treatment Outcomes and Safety
- Treatment of hemochromatosis can lead to significant reductions in iron burden and improvement in clinical outcomes, particularly if initiated before end-organ damage occurs 5.
- Deferasirox has been shown to be well-tolerated in patients with hereditary hemochromatosis, with common adverse events including diarrhea, nausea, and headache 3, 4.
- The safety and efficacy of deferasirox have been demonstrated in several studies, with starting doses of 10 mg/kg/day appearing to be most appropriate for further study in this patient population 3.
