Background Thalassemia is associated with the generation of labile iron in the red blood cells, which promotes the formation of reactive oxygen species, leading to cumulative cell damage. Ischemia modified albumin (IMA) is now suggested to reflect generalized oxidative stress. Objectives The aim of this study was to evaluate IMA in children with transfusion-dependent (TD) β-thalassemia and its relation with serum ferritin and iron chelation therapies. Patients and methods A total of 60 children with TD thalassemia were divided into three groups on the basis of the type of iron chelation therapy received: group A received oral deferiprone (DFP), group B received effervescent deferasirox (DFX), and group C did not receive any type of iron chelation therapy. A total of 20 age-matched and sex-matched healthy children were included as controls. Serum ferritin and IMA were determined for all participants. Results There were significant increases in serum ferritin and IMA levels in thalassemic children than in controls (P < 0.001 for each). Children on DFP and DFX had significantly lower IMA levels compared with children not receiving any iron chelation therapy (P < 0.001 and 0.01, respectively). Serum ferritin had a positive significant association with IMA (r = +0.27 and P = 0.03). Conclusion IMA was higher in children with TD thalassemia than in controls. Moreover, its level in thalassemic children on either DFP or DFX was significantly lower than its level in children not receiving any chelation therapy. Therefore, IMA may be a possible marker of iron-induced oxidative stress in β-thalassemia.
