About 25% of children with sickle cell disease (SCD) have statural deficit and retarded skeletal maturation and pubertal development. These disorders have been attributed to low serum concentrations of zinc. We report the study of serum zinc in 34 patients with SCD, of whom 17 had statural deficit (SCS group) and 17 without growth deficiency (SCN group). They were compared with 20 normal children (N group). GH secretion and thyroid function were investigated in the group with short stature (SCS) in order to rule out GH deficiency and hypothyroidism. The mean serum zinc concentration was 108.45+/-22.888 microg/100 ml in the N group, 87.529+/-30.069 microg/100 ml in the SCN group and 82.765+/-34.766 microg/100 ml in the SCS group. There was a statistically significant difference between the mean of the N group and the mean of the SCN group (p<0.05) but no difference was found between the two groups of patients (N>SCN=SCS). Although there is a well-established zinc deficiency in patients with SCD, the statural retardation found in the SCS group could not be attributed only to zinc deficiency. Many other severe metabolic disturbances are also involved.
