title: Advances in the treatment of precocious puberty.
abstract: The development of immunoassay techniques for accurately measuring serum gonadotropins and gonadal steroids allows distinction between central (GnRH-dependent) and peripheral (GnRH-independent) precocious puberty in children. Previously (see case 3) it was not possible to do this, and a rational approach to therapy could not be designed. Significant advances in the synthesis of superagonists of gonadotropin-releasing hormone have allowed effective treatment for children with CPP. Such treatment has only been possible for the past 10 to 15 years, and GnRHa have been approved for use in the United States for this indication only since 1992. Long-term studies are still needed to determine what effect, if any, such treatment has on fertility, because only a few patients, even from the earliest studies, have reached child-bearing age. All indications, however, suggest that treatment with GnRHa is reversible, as well as safe and efficacious. More challenging is the effective treatment of PPP, for which innovative approaches involving inhibition of gonadal steroid synthesis or action have met with some success. Again, long-term studies or efficacy and safety are needed.
