Abstract
BackgroundOsteomalacia and osteoporosis are a common clinical problem in patients with beta thalassemia major. The purpose of this study is to assess the possible correlation of excess iron in liver and heart of beta thalassemia patient with bone mineral density (BMD).Materials and methodsWe performed a prospective cross-sectional study on 80 patients with beta thalassemia major and inermedia. The patients were stratified into normal BMD and those with abnormal BMD test based on T-score. All patients underwent magnetic resonance imaging examinations of heart and liver. Multi-echo fast gradient-echo sequence was used and T2* values were calculated based on the Royal Brompton Hospital protocol. Correlations between T2* values in heart and liver as well as serum ferritin levels with femoral and lumbar BMD were investigated.ResultsThere were no significant differences between patients with and without osteopenia or osteoporosis with respect to age and sex. Patients with abnormal BMD had lower T2* values in the heart. Serum ferritin and heart iron load (based on T2*) were negatively correlated with BMD.ConclusionSerum ferritin and heart iron content are good indicators of BMD in patients with beta thalassemia major and intermedia.
