Dharmesh,
The scores are of great concern, but I have seen similar reversed by a total commitment to chelation compliance. Ideally, combination therapy should be used. High dose Exjade or Asunra, at 40 mg/kg has shown to be effective for reducing high iron loads, but side effects can make this a difficult long term strategy. I would definitely recommend adding desferal at least twice weekly. I have seen patients turn things around using various strategies. These are some of the strategies.
Desferal 7 days a week for at least 12 hours each time.
IV desferal 24/7 and kelfer (Ferriprox).
Exjade at maximum dosage along with desferal several times per week.
All 3 chelators in combinations of no more than 2 at one time (this method worked well for an experienced patient who developed this on his own).
The key is a total commitment to chelation. There can be no excuses. Chelation has to come first in your life. A thal mom I know used desferal 7 days a week. She started with a T2* of 8. After one year, it was 13.8. After two years it was over 20.
Stay committed. Report your progress and lean on us for support. You can do this, so don't let the scores scare or depress you. I have seen patients with ferritins over 13,000 bring them down to under 1000 and even much lower by staying focused. You can and will succeed as long as you decide you will.
