“…-thalassemia/HbE based on the pathogenesis of the disease is milder than -thalassemia homozygous for patients with -thalassemia/HbE be able to compen-sate for anemia than -thalassemia homozygous due to the nature of HbE and mean level of HbF lower than mean level of HbF -thalasemia homozygous (Fucharoen & Weatherall, 2012) so that the number of transfusions in patients with thalassemia type -thalassemia homozygous were more than thalassemia patients with -thalassemia/HbE type so Ferritin and MDA production was higher in patients with -thalassemia homozygous (Goswami, et al, 2005). In this study, in addition to the homozygous ß-thalassemia patients had a higher level of MDA than -thalassemia/HbE patients, but also had lower level of serum Ferritin, probably because homozygous -thalassemia patients had a younger mean age, shorter length of disease, and better nutritional status than thalassemia-/HbE subjects (Gunarsih, et al, 2012).…”
