Treatment of children with central precocious puberty by a slow-release gonadotropin-releasing hormone agonist.

Abstract

A total of 82 patients (74 girls, 8 boys) are presently participating in an international multicentre trial for treatment of central precocious puberty (CPP) with a slow release gonadotropin-releasing hormone (GnRH) agonist depot preparation: Decapeptyl-Depot (DD). Of these patients, 53 (3 boys) were previously untreated (group 1) and 29 (5 boys) have been treated before with either a short-acting GnRH analogue or cyproterone acetate (group 2). Fifty-one patients (44 girls, 7 boys) were treated with DD for 12 months or more. Basal plasma luteinizing hormone (LH) levels decreased in both groups after 1 year of therapy. The LH response to intravenous GnRH was reduced in both groups. Basal plasma follicle stimulating hormone (FSH) levels decreased in both groups. Stimulated FSH levels were reduced in both groups after 1 year of DD treatment. Plasma oestradiol levels in the girls decreased to prepubertal levels in both groups. In all patients the clinical signs of precocious gonadarche such as breast development and menstruations (girls) and an increased testis volume (boys), did not further progress and sometimes regressed in several patients. Growth velocity decreased in the girls of group 1 from 9.0 +/- 0.72 cm/year (mean +/- SEM) in the last half-year before treatment to 6.3 +/- 0.50 in the first half-year of treatment (P less than 0.01) and to 4.5 +/- 0.23 cm/year in the second half-year (P less than 0.01). After 12 months a stabilization of growth velocity was observed.(ABSTRACT TRUNCATED AT 250 WORDS)
