    Summary

    Desferrioxamine (DF) effectively manages iron overload in transfusion-dependent thalassemia major patients. Subcutaneous DF administration helps achieve iron balance with no significant adverse effects observed.

    Area of Science:

    • Hematology
    • Pediatrics
    • Pharmacology

    Background:

    • Iron overload is a primary cause of mortality in thalassemia major and other congenital anemias.
    • Organ damage, particularly in the liver, endocrine glands, and heart, results from iron overload.
    • Desferrioxamine (DF) is the established treatment for iron chelation therapy.

    Purpose of the Study:

    • To evaluate the efficacy and safety of desferrioxamine (DF) in managing iron overload in beta-thalassemia major and intermedia patients.
    • To assess the impact of subcutaneous DF administration on iron balance in young thalassemia major patients.

    Main Methods:

    • Subcutaneous administration of desferrioxamine (DF) at a dosage of 40 mg/kg/day.
    • Monitoring iron balance in patients with thalassemia major.
    • Clinical assessment and periodic slit-lamp examinations for ocular alterations in treated subjects.

    Main Results:

    • Subcutaneous DF administration (40 mg/kg/day) achieved iron-negative balance in thalassemia major patients from three years of age.
    • No significant adverse effects were reported during the study.
    • Ocular examinations revealed no alterations in 35 evaluated subjects.

    Conclusions:

    • Subcutaneous desferrioxamine (DF) is an effective and safe treatment for iron overload in transfusion-dependent beta-thalassemia major.
    • Patients with thalassemia intermedia also experience iron overload due to increased absorption, necessitating early intervention to reduce iron absorption and prevent complications.
