Relationship between serum ferritin and growth status of pediatric transfusion dependent thalassemia.

Background: Growth retardation is a long-term complication in pediatric transfusion-dependent thalassemias (TDTs), presented as short-stature and upper body segment shortening. The cause of this condition was chronic hypoxia, iron overload, endocrinopathy, inadequate transfusion, and iron chelation. We analyze the relationship between ferritin level and growth status of pediatric TDTs.

Relationship between Bax and Bcl-2 Protein Expression and Outcome of Induction Phase Chemotherapy in Pediatric Acute Lymphoblastic Leukemia.

Background: Overexpression of the antiapoptotic protein Bcl-2 causes apoptosis to stop and conversely the increased expression of the proapoptotic protein Bax makes lymphoblasts easy to destroy. The Bax/Bcl-2 ratio plays a role in the balance of apoptosis, immortality, resistance, and outcome of chemotherapy. We analyzed the relationship between the Bax/BCl-2 ratio and the outcome of induction phase chemotherapy in pediatric Acute Lymphoblastic Leukemia (ALL).
