The influence of gonadotropin-releasing hormone agonists on anthropometric change in girls with central precocious puberty
Jong Wan Yoon, Hyun A Park, Jieun Lee, Jae Hyun Kim
Clin Exp Pediatr. 2017;60(12):395-402.   Published online December 22, 2017
Purpose

The potential effect of gonadotropin-releasing hormone agonist (GnRHa) treatment on the weight of girls with central precocious puberty (CPP) remains a controversy. We investigated anthropometric changes during and after GnRHa treatment among girls with CPP.

Methods

This retrospective study evaluated data from 127 girls with CPP who received GnRHa treatment for ≥2 years. Height, weight, and body mass index (BMI) values were...

Long-term effects of gonadotropin-releasing hormone analogs in girls with central precocious puberty
Eun Young Kim
Clin Exp Pediatr. 2015;58(1):1-7.   Published online January 31, 2015

Gonadotropin-releasing hormone analogs (GnRHa) are widely used to treat central precocious puberty (CPP). The efficacy and safety of GnRHa treatment are known, but concerns regarding long-term complications are increasing. Follow-up observation results after GnRHa treatment cessation in female CPP patients up to adulthood showed that treatment (especially <6 years) was beneficial for final adult height relative to that of pretreated...

Excess of leptin inhibits hypothalamic KiSS-1 expression in pubertal mice
Sung Yeon Ahn, Sei Won Yang, Hee Jae Lee, Jong Seon Byun, Ji Yeon Om, Choong Ho Shin
Clin Exp Pediatr. 2012;55(9):337-343.   Published online September 14, 2012
Purpose

Leptin has been considered a link between metabolic state and reproductive activity. Defective reproductive function can occur in leptin-deficient and leptin-excessive conditions. The aim of this study was to examine the effects of centrally injected leptin on the hypothalamic KiSS-1 system in relation to gonadotropin-releasing hormone (GnRH) action in the initial stage of puberty.

Methods

Leptin (1 µg) was injected directly into...

Effects of human growth hormone on gonadotropin-releasing hormone neurons in mice
Janardhan P. Bhattarai, Shin Hye Kim, Seong Kyu Han, Mi Jung Park
Clin Exp Pediatr. 2010;53(9):845-851.   Published online September 13, 2010
Purpose

Recombinant human growth hormone (rhGH) has been widely used to treat short stature. However, there are some concerns that growth hormone treatment may induce skeletal maturation and early onset of puberty. In this study, we investigated whether rhGH can directly affect the neuronal activities of of gonadotropin-releasing hormone (GnRH).

Methods

We performed brain slice gramicidin-perforated current clamp recording to examine the direct...

Clinical application of gonadotropin-releasing hormone analogs in children and adolescents
Ho-Seong Kim
Clin Exp Pediatr. 2010;53(3):294-299.   Published online March 15, 2010
Although the increasing incidence of central precocious puberty (CPP) in Korea has recently raised public concerns about health and growth problems, there are many areas of uncertainty regarding the pathogenesis, diagnosis, and management of CPP. In this paper, we review the definition of precocity, the assessment of CPP, and the hormonal abnormalities that support the diagnosis. In addition, we review...

Analysis of gonadotropin-releasing hormone (GnRH) test results in girls with precocious puberty
Jung Yun Choi, Hyun-Ju Kang, Won Kyoung Cho, Kyoung Soon Kim, So Hyun Park, Seung Hoon Hahn, Min Ho Jung, Byung Kyu Suh, Byung Churl Lee
Clin Exp Pediatr. 2009;52(12):1377-1382.   Published online December 15, 2009
Purpose : The gonadotropin-releasing hormone (GnRH) test results of girls with precocious puberty were analyzed to determine whether this test can efficiently and clearly differentiate between central precocious puberty (CPP) and other disorders. Methods : Clinical and laboratory data of 54 girls with precocious pubertal signs were reviewed. Intravenous GnRH test was performed with blood samples obtained at 0, 30,...
A comparative study of the puberty suppression effect of gonadotropin-releasing hormone agonist in precocious or early puberty girls
Kye-Shik Shim, Chong-Woo Bae, You-Jung Yang
Clin Exp Pediatr. 2008;51(6):634-639.   Published online June 15, 2008
Purpose : There has been considerable disagreement regarding the most appropriate dosage of gonadotropin-releasing hormone agonist in cases of central precocious puberty. The aim of this study was to determine the appropriate dosage for suppression of the puberty in girls with central precocious or early puberty. Methods : Twenty-two girls with early puberty were randomly subjected to 3 types of dosages...
The comparison of predicted adult height change and height gain after gonadotropin-releasing hormone agonist and combined growth hormone treatment in girls with idiopathic central precocious puberty
Ji-Young Seo, In-Suk Yoon, Choong-Ho Shin, Sei-Won Yang
Clin Exp Pediatr. 2006;49(3):305-311.   Published online March 15, 2006
Purpose : GnRH analogues(GnRHa) are used to treat central precocious puberty(CPP). However, in some patients, the GV decrease is so remarkable that it impairs predicted adult height(PAH); and there fore, the addition of growth hormone(GH) is suggested. We analysed the growth changes during two years and final adult height(FAH) in girls with idiopathic CPP treated with combined therapy, compared with...
