Abstract

A serious problem in thalassemia major is growth impairment for which several possible etiologies have been proposed. Sixty-seven patients with thalassemia were randomly enrolled into the study, divided into 2 groups with and without growth failure and the correlation between growth failure and the following parameters was evaluated: age, sex, serum ferritin level, serum zinc and copper concentrations, serum copper-zinc ratio, regularity of blood transfusion, and the regularity and duration of chelation therapy. Among all studied parameters, only age, duration, and type of chelation therapy and age of beginning chelation therapy were significantly different between the 2 groups. Binomial multivariate logistic regression showed that the only significant independent correlation was between age and growth failure. A 1-year increase in age is associated with a 1.57-fold increase in the risk of growth impairment. The results of this study indicated that a temporally cumulative damage to growth-mediating mechanisms except those considered here is responsible for growth failure in thalassemia major.
