  • Title: Age of appearance of circadian rhythm in blood 17-hydroxyprogesterone in 21-hydroxylase deficiency.
    Author: Sólyom J.
    Journal: Acta Physiol Hung; 1991; 78(2):107-10. PubMed ID: 1808976.
    Abstract:
    Sixty-one daily profiles of blood-spot 17-hydroxyprogesterone derived from patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency were analysed to determine the age of appearance of circadian rhythm in hypothalamo-pituitary-adrenal activity. The results revealed that typical circadian adrenocortical rhythm is established at approximately three months after birth. In conclusion, the maturation of supra-hypothalamic brain structure proceeds normally also in humans with constant low level of cortisol in blood.
