[Hormonal suppression and sexual development in children with central precocious puberty in the first treatment cycle 12 weeks after injection of triptoreline 11.25 mg (Diphereline S. R. 11.25 mg): a pilot study].
OBJECTIVE
To evaluate hormonal suppression and pubertal development in children with central precocious puberty (CPP) after injection of triptoreline 11.25 mg (Diphereline S. R. 11.25 mg; Ipsen) in the first treatment cycle of 12 weeks.


METHODS
Pilot study.


METHODS
Paediatric department, University Hospital Motol-Prague.


METHODS
Serum levels of FSHmax and LHmax and basal levels of estradiol/testosterone were monitored in GnRH test before, 4, 8 and 12 weeks after triptoreline 11.25 mg injection in 3 girls and 2 boys with CPP (age 3.9-10.6 years) previously treated by triptoreline 3 mg every 4 weeks. Uterine and ovarian volume, hormonal cytology (vaginal smear), breast development and testicular volume were evaluated before and 12 weeks after triptoreline 11.25 mg injection.


RESULTS
8 weeks after triptoreline 11.25 mg, FSHmax in girls increased (2.3 IU/l vs. 1.7 IU/l before injection; median) without any other change in 12th week. In boys after initial decrease LHmax 12 weeks after injection rose to 1.7 IU/l (identical as LHmax before injection). Estradiol and testosterone levels were in prepubertal range. Pubertal development in girls did not progress, and testicular volume decreased in both boys (treated for CPP 0.3 and 0.7 years).


CONCLUSIONS
Triptoreline 11.25 mg injection in 12 weeks interval can be considered as effective, useful and safe for therapy of CPP. The long-term follow-up will be necessary.
