Summary

Early identification of precocious puberty is key. Treatment with LH-RH analogs improved height prognosis in girls with poor initial height, while those with good prognosis maintained their growth potential.

Area of Science:

  • Pediatric Endocrinology
  • Growth and Development

Background:

  • Precocious puberty can impact adult height.
  • Differentiating height prognosis is crucial for treatment decisions.

Purpose of the Study:

  • To evaluate the effectiveness of LH-RH analog treatment on predicted adult height (P.A.H.) in girls with precocious puberty.
  • To distinguish between 'poor' and 'good' height prognoses at initial evaluation.

Main Methods:

  • Utilized Bayley-Pinneau predicted adult height (P.A.H.) to stratify 26 girls with precocious puberty into two groups.
  • Group 1 (P.A.H. < -1 SDS) received immediate LH-RH analog treatment.
  • Group 2 (P.A.H. > -1 SDS) was observed without therapy.

Main Results:

  • LH-RH analog treatment significantly improved P.A.H. in Group 1 (from -1.68 to -0.57 SDS, p < 0.01).

  • Group 2 showed no significant change in P.A.H. over 2 years (from 0.45 to 0.33 SDS).

    • Conclusions:

    • LH-RH agonist therapy enhances height potential in girls with precocious puberty and an initially poor height prognosis.
    • Girls with precocious puberty and a good initial height prognosis maintain their growth potential without immediate treatment.
