  • Title: Prolonged activation of hypothalamo-pituitary-ovarian axis during early infancy in female patients with salt-losing 21-hydroxylase deficiency.
    Author: Maesaka H, Suwa S, Tachibana K, Katsumata N.
    Journal: Pediatr Res; 1985 Dec; 19(12):1258-62. PubMed ID: 3936012.
    Abstract:
    We observed prolonged genital bleeding during the first 2-3 months after treatment in five of 13 female patients with salt-losing 21-hydroxylase deficiency. Their relatively low concentrations of serum follicle-stimulating hormone and luteinizing hormone before therapy increased rapidly to high levels which were maintained for 1-3 wk and then decreased. The duration of these relatively high levels after therapy was longer in the patients with genital bleeding than those without. Before therapy, there was no release of serum follicle-stimulating hormone and luteinizing hormone following the administration of synthetic luteinizing hormone-releasing hormone in two patients; 1 month after therapy, the response to luteinizing hormone-releasing hormone increased significantly. Serum estradiol increased above 300 pg/ml in four patients with genital bleeding but was less than 175 pg/ml in three patients without bleeding. The etiology of genital bleeding in these female patients may be more prolonged activation of the hypothalamo-pituitary-ovarian axis and a greater increase in the responsiveness of internal genitalia to gonadotropins and sex hormones, perhaps induced by prolonged exposure to excessive adrenal steroids starting before birth.
