This protocol addresses alpha thalassemia minor in patients with deletional haemoglobin H (HbH) disease — a specific subtype where iron accumulation over time may require active management despite often mild clinical presentation.
Individuals with deletional HbH disease typically present with mild, often asymptomatic anaemia. The condition frequently goes unrecognised until an incidental laboratory finding prompts further workup. Once confirmed, surveillance for progressive iron burden becomes part of long-term care.
When iron accumulation reaches defined thresholds — assessed through liver iron concentration and serum ferritin — iron chelation therapy is indicated. The specific triggers, agent choice, monitoring protocol, and stopping criteria are detailed in the full structured regimen.
The clinical goals are to bring liver iron concentration below 3 mg/g dry weight and serum ferritin below 300 ng/mL.
