Summary

Deflazacort (DF) has been claimed to be provided with a reduced distribution into the central nervous system, therefore it is conceivable that this glucocorticoid holds a lower inhibitory effect on GH secretion. To test this hypothesis we studied the GH response to insulin tolerance test (ITT) in two matched groups of patients given equivalent doses of DF and prednisone (PN). The serum glucose changes induced by ITT were similar in the two groups and in control subjects; the mean increase in plasma GH, in particular the peak and the area under the curve (Δ AUC), were not different in control subjects and DF-treated patients (25±12.5 ng/ml and 1790±904 ng/ml/min versus 27.7±21.5 ng/ml and 1578±1242 ng/ml/min) but were significantly reduced in PN-treated patients (8.8±9.7 ng/ml and 431.6±451 ng/ml/min). Our study demonstrates that DF does not interfere with the GH response to ITT as PN does.
