Objective This study was performed to assess cardiac and hepatic iron overload in young patients with thalassemia. Methods We reviewed the medical records of patients with thalassemia at a pediatric hematology clinic who had recently undergone cardiac and hepatic magnetic resonance imaging. Results Eleven patients underwent cardiac and hepatic T2* imaging at a mean age of 13.9 ± 4.48 (range, 9–21) years. Three patients had cardiac iron overload and all patients had hepatic iron overload according to the magnetic resonance imaging scan. Ten patients underwent control imaging approximately 1 year later. The mean serum ferritin level at the initial imaging examination was 1820.87 ± 1275.22 (range, 634.04–4221.03) ng/mL. There was a strong negative correlation between the ferritin level and cardiac T2* time and between the blood hemoglobin level and hepatic T2* time. Among the 10 patients who underwent control imaging, the average hemoglobin and ferritin levels significantly decreased from the initial to control imaging examinations, but there was no significant increase in the cardiac and hepatic T2*times. Conclusions Cardiac and hepatic T2* imaging is a feasible method of assessing cardiac and hepatic iron overload even before complications and clinical signs of iron overload appear.

Abstract Background: Non-transfusion-dependent thalassemia (NTDT) is a term used to indicate patients who do not require lifelong regular transfusions for survival. Morbidity in NTDT patients is more common and serious than previously recognized. This study aimed to examine the association of age with the presence of iron overload assessed by Magnetic Resonance Imaging (MRI) and cardiovascular and endocrine complications in NTDT patients. Methods: We considered 170 patients with thalassemia intermedia never transfused o who received occasional transfusions consecutively enrolled in the Myocardial Iron Overload in Thalassemia (MIOT) project. Iron overload was quantified by the T2* Magnetic Resonance Imaging (MRI) technique. All complications were classified according to international guidelines. Results: Six groups of patients were identified: age<18 years (N=7), age 18-30 years (N=36), age 30-40 years (N=48), age 40-50 (N=45), age 50-60 years (N=26), and age≥60 years (N=8). The Table shows the comparison among the groups. The youngest patient showing hepatic iron (MRI liver iron concentration-LIC>3 mg/g dw) had 9 years of age and the frequency of hepatic iron did not significantly increase with age. Only one patient showed cardiac iron (global heart T2*<20 ms). Diabetes appeared only in patients with more than 50 years and showed a trend toward increasing with increasing age. Hypothyroidism and osteoporosis were not present in pediatric patients and were not associated to age. Hypogonadism was not present in patients with less than 30 years and its frequency was comparable among the age groups. No patient showed hypoparathyroidism. Only patients older than 30 years showed a cardiac complication (heart failure or arrhythmias), but the rate did not significantly increase with increasing age. Conclusions: Our data in NTDT are indicative of high rate of liver iron overload at early age and extremely rare cardiac iron overload. Endocrine or cardiac complications were not present in pediatric patients but in adult patients the frequency did not increase with advancing age. Table. Table.

Abstract Background Thalassemia is the most prevalent single-gene disorder. Myocardial and hepatic iron depositions lead to complications and eventually death. We aimed to assess the diagnostic efficacy of magnetic resonance imaging T2* (MRI T2*) in quantifying iron overload in liver and heart in transfusion-dependent B-thalassemia major (TDT) children. Methods Prospective clinical study was carried on sixty children diagnosed with TDT. All of them underwent laboratory investigations, including CBC, serum iron, and ferritin levels. MRI T2* of the heart and liver was carried out to measure the iron overload and estimate the left ventricular ejection fraction (LVEF). Results Thirty-eight males and 22 females with TDT with a mean age of 13.23 years were included. Twenty cases (33.3%) had severe liver iron overload, while 36 (60%) had normal cardiac iron. There was a moderate significant negative association between hepatic and cardiac iron deposition (P = 0.03). All cases with severe cardiac iron overload had impaired LVEF below 56%. A non-significant positive association was noticed between cardiac iron deposition and LVEF in T2* (P = 0.08). A moderate negative significant association was detected between hepatic iron deposition and serum ferritin, while a fair negative significant association was found between serum ferritin and cardiac iron deposition with P values of 0.04 and 0.02, respectively. Conclusion MRI T2* is the gold standard for monitoring and follow-up of iron overload in the heart and liver. It should be routinely performed in all TDT children as liver iron, and serum ferritin do not reflect cardiac iron overload.
