title: Long-term results of long-acting luteinizing-hormone-releasing hormone agonist in central precocious puberty.
abstract: Thirty children with precocious puberty (24 girls aged 6.5 +/- 2.3 years and 6 boys aged 7 +/- 2.9 years) were treated over 5 years with Decapeptyl. In girls, the menses disappeared, breast enlargement regressed, and uterus and ovary sizes returned to prepubertal values. In boys, a significant decrease of testicular size was observed. Plasma levels of estradiol and testosterone, and basal and post-luteinizing hormone (LH)-releasing hormone (LHRH) LH and follicle-stimulating hormone (FSH) remained in the prepubertal range. Growth velocity decreased after 1 year from 9.7 +/- 3.5 to 5.5 +/- 1.3 cm/year, while the height age/bone age ratio was normalized in both sexes after 3 years. In 15 girls, Decapeptyl was interrupted after 2.3 years. During those 2.3 years, bone age increased from 11.6 +/- 0.8 to 12.5 +/- 0.7 years with a growth velocity of 5.3 +/- 1.8 cm/year. During the year following interruption, height increased from 152.2 +/- 4.9 to 157.7 +/- 4.9 cm (growth velocity 5.5 cm/year) and bone age from 12.5 +/- 0.7 to 13.5 +/- 0.6 years. One year after treatment, plasma levels of estradiol were 106.7 +/- 84.7 pg/ml, of LH, 25.5 +/- 17.6 mIU/ml, and of FSH, 10.8 +/- 5.9 mIU/ml. Menses appeared in 13 girls. Moreover, 18 months after interruption, bone age was 13.9 +/- 0.6 years and height 159.5 +/- 5.2 cm, being significantly superior to the final height of a historical control group: 151.5 +/- 4.8 cm (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
