How to manage elevated ferritin levels (hyperferritinemia) of 903?

From the Guidelines

To manage a ferritin level of 903, therapeutic phlebotomy should be initiated, with the goal of reducing ferritin levels to a target range of 50-100 ng/mL, as recommended by the most recent guidelines 1. The treatment approach typically involves removing 400-500 mL of blood every 1-2 weeks until ferritin levels normalize, followed by maintenance phlebotomies every 1-4 months to maintain the target range.

• Key considerations in managing high ferritin levels include:
  • Regular monitoring of serum ferritin, haemoglobin, and liver function to track progress and adjust treatment
  • Dietary modifications to limit iron-rich foods and enhance iron absorption inhibitors
  • Potential iron chelation therapy if phlebotomy is not suitable
  • Monitoring for complications such as iron deficiency, liver damage, and cardiac disease
• The most recent guidelines from the Journal of Hepatology 1 provide a strong recommendation for therapeutic phlebotomy as the primary treatment approach for managing high ferritin levels.
• It is essential to consult with a healthcare provider to determine the best course of treatment and to monitor progress regularly, as excessive iron can damage organs like the liver, heart, and pancreas over time.
• The frequency of phlebotomy should be adjusted based on the patient's iron status, and serum haemoglobin should be monitored to avoid iron deficiency, as recommended by the guidelines 1.

From the FDA Drug Label

If the serum ferritin falls below 1000 mcg/L at 2 consecutive visits, consider dose reduction, especially if the deferasirox tablets dose is greater than 17.5 mg/kg/day If the serum ferritin falls below 500 mcg/L, interrupt deferasirox tablets therapy and continue monthly monitoring. Use the minimum effective dose to achieve a trend of decreasing ferritin Make dose adjustments in steps of 3.5 or 7 mg per kg and tailor adjustments to the individual patient’s response and therapeutic goals.

For a ferritin level of 903, consider dose reduction since it is below 1000 mcg/L. The dose reduction should be done in steps of 3.5 or 7 mg per kg. It is also important to continue monthly monitoring of serum ferritin levels to assess the need for further dose adjustments. The goal is to use the minimum effective dose to maintain a low iron burden while minimizing the risk of adverse events 2.

Managing Elevated Ferritin Levels

To manage a ferritin level of 903, it is essential to consider the underlying cause of the elevation. In cases of iron overload, iron chelation therapy is often employed to reduce ferritin levels and alleviate associated complications.

Iron Chelation Therapy

• Deferoxamine (DFO), deferiprone (DFP), and deferasirox (DFX) are commonly used iron chelating agents 3.
• These agents have their own advantages and risks, and the choice of therapy depends on various factors, including the severity of iron overload and patient tolerance 3.
• Studies have shown that combination therapy with multiple iron chelators can be effective in reducing ferritin levels and improving outcomes in patients with transfusion-dependent β-thalassemia 4, 5.

Comparison of Iron Chelators

• A meta-analysis of 16 randomized controlled trials compared the efficacy and safety of DFO, DFP, and DFX in patients with thalassemia major 6.
• The results showed that combined therapy with DFP and DFO was more effective in reducing myocardial iron content and improving left ventricular ejection fraction compared to DFO alone 6.
• Another study found that deferiprone was non-inferior to deferoxamine in reducing liver iron concentration and serum ferritin levels in patients with sickle cell disease and other anemias 7.

Treatment Strategies

• For patients with very high iron overload, triple combination therapy with deferoxamine, deferasirox, and deferiprone may be considered 5.
• Regular monitoring of serum ferritin levels, liver iron concentration, and cardiac iron content is crucial to assess the efficacy of iron chelation therapy and adjust treatment strategies as needed 4, 5.
• Patients should be closely monitored for adverse events and side effects associated with iron chelation therapy, such as gastrointestinal symptoms, liver enzyme elevations, and neutropenia 7.
