Effect of complete suppression of androstenedione on auxological development in prepubertal patients with classical congenital adrenal hyperplasia.

With guideline-compliant doses of hydrocortisone, suppression of A4 at the respective time of day is possible in prepubertal children. Although HC has a significant negative influence on HSDS, increasing values for HSDS and HC are observed with increasing age. Thus, A4 suppression at the respective time point does not hinder regular growth. An increase in body mass index can already be observed as early as in prepuberty.
