Treatment with Deferiprone (LI) in a Thalassaemic Patient with Bone Lesions due to Desferrioxamine

Abstract

A male thalassemia major patient who developed bone and cartilage abnormalities with a standard dose of desferrioxamine (DFX) given subcutaneously from the age of 4 years was treated with the oral iron chelator deferiprone (L1). During L1 treatment an improvement of genu valgum, evidence of healing and filling in of bone at the periphery of knee metaphysis and improvement in growth velocity were observed. However, the sitting height had decreased further, confirming the irreversibility of platyspondylosis, so affecting the near final standing height (156.8 cm) which was below the mid-parental height (168 cm). Prospective studies are warranted to determine the effect of different iron chelators on the bone metabolism of patients with thalassemia.
