Thalassemia is a term that refers to a group of genetic disorders characterized by a defect in the synthesis of hemoglobin. It is sometimes called Mediterranean anemia. Many biochemical changes in the blood accompany this disease. In this research, some biochemical parameters were measured in thalassemic patients and compared with healthy control group. These parameters include Serum iron, TIBC, were measured Spectrophotometrically. Serum ferritin, Iisulin, GH, Testosterone, T3, T4, TSH, Cortisol, & Prolactine were measured by ELISA technique. The results have revealed a moderate state of iron overload in the thalassemia patients. Furthermore, there is a decrease in the level of serum cortisol, T4, prolactine and pancreatic beta cell function percentage (HOMA% B) in thalassemic while serum TSH level is higher in thalassemic patients in comparing with control group. The changes in the hormone levels …
