Two Chinese studies in 35 consecutive patients with thalassemia on a hypertransfusion scheme plus chelation therapy have confirmed that deferoxamine-induced bone dysplasia was associated with height reduction and occurred at doses below 50 mg/kg/day (107,108). 

In the first study, the patients had radiography of the left hand for bone age determination, and 12 had deferoxamine-induced long bone dysplasia (107). There was irregularity at the physeal-metaphyseal junction of the distal ulna (the site most frequently affected) and radius metaphyseal sclerosis was also common, especially of the ulna, but also of the radius, metacarpals, and phalanges. Radiolucent lesions occasionally accompanied metaphyseal sclerosis. In six patients with relatively mild lesions, the dysplastic changes had been missed or not mentioned.

Musculoskeletal In a retrospective series of 84 children receiving deferoxamine for trans-fusion-related hemochromatosis (P-thalasse-mia, E/p-thalassemia, or a-thalassemia) bone dysplasia occurred in 17 [39 ]. The standard dose was 25-50 mg/kg/day subcutaneously over 10 hours on 5-7 nights a week three patients received short-term intravenous deferoxamine at some point during the study.

There has been little change during the last 14 years (Figures 16.1-5). Some improvement occurs in warm weather and temporary improvement follows treatment with keratolytics and moisturizers. Vitamin A (systemic and topical) has had no effect. In 1976 he was admitted for further investigations. There was no radiological evidence of bone dysplasia. The serum proteins were normal. The serum triglycerides and cholesterol were normal on three occasions. There was no evidence of essential fatty acid deficiency. Amino acid...
