Background and objective :  Iron overload is an essential problem causing several complications in thalassemic patients, necessitating early diagnosis and treatment.  MRI T2* is widely accepted for measuring iron overload in the heart and liver. This study aim to evaluate the heart and liver iron concentration using MRI T2* at different levels of serum ferritin.

Patients and Methods:  We selected 30 patients with thalassemia intermedia; whose serum ferritin was 600–1,000, 1,001–2,000 and >2,000 mcg/ml.  Heart and liver MRI T2* were performed.   Iron markers and liver function were rechecked  on the same day of  MRI performing.

Results:  Twenty patients had HbEb-thalassemia: 3 HbH with Hb Constant Spring; 6 HbH with Hb Constant Spring and heterozygous HbE; and, 1 HbH with Hb Pakse and heterozygous HbE.  Median age was 14 years (range 10–31). All patients had non-transfusion dependent thalassemia but most received regular PRC transfusions every 3–4 weeks.  No cardiac abnormalities were found.  Of the patients with a respective serum ferritin <1000 and <800 mg/ml, 50% and 25% (6/12 and 2/8, respectively) had a median LIC >7 mg/g dry weight.  Serum ferritin had a fair correlation with LIC as did ALT:  both were statistically significant.

Conclusions:  Liver MRI T2* revealed iron overload in thalassemia intermedia at low serum ferritin levels.  More information is needed for reconsidering guidelines on investigation and treatment for iron overload in these patients.
