Eight children with congenital adrenal hyperplasia and late initiation of corticosteroid treatment are included in the present study. Four of them received LHRHa treatment for the arrest of central precocious puberty, while the other four served as controls. The administration of LHRHa was effective in arresting the manifestations of puberty. The final height in the LHRHa-treated group was 158.2 +/- 7.3 cm (SDS -1.1 +/- 0.5) and did not differ from the target height of 158.9 +/- 6.5 cm (SDS -1.1 +/- 0.2), while the final height in the controls was 153 +/- 11 cm, a value significantly lower than their target height of 164.5 +/- 8.3 (SDS -0.6 +/- 0.7) with p < 0.05. The data showed that LHRHa is effective in arresting central precocious puberty and appears to improve final height, bringing it closer to that expected from the genetic potentials.

Introduction: In light of the recent evidence suggesting an increase in idiopathic central precocious puberty (ICPP) during the COVID-19 pandemic, this study aimed to assess the incidence of newly diagnosed ICPP cases and compare differences in demographic, anthropometric, and clinical characteristics pre-pandemic and during the pandemic.
Methods: We conducted a retrospective study at a national reference pediatric endocrinology unit in Portugal to evaluate the proportion of referrals for precocious puberty (PP) and, within this group, the number of ICPP cases diagnosed before (group 1: January 2018 to March 2020) and during the pandemic (group 2: April 2020 to June 2022). Additionally, we compared the demographic, anthropometric, and clinical characteristics of ICPP patients between the two groups.
A novel model of central precocious puberty disease: Paternal MKRN3 gene-modified rabbit.

Background: Makorin ring finger protein 3 gene (MKRN3) gene mutation is the most common genetic cause of central precocious puberty (CPP) in children. Due to the lack of ideal MKRN3-modified animal model (MKRN3-modified mice enter puberty only 4-5 days earlier than normal mice), the related research is limited.
Methods: Therefore, the MKRN3-modified rabbit was developed using CRISPR (clustered regularly interspaced short palindromic repeats) gene editing technology.
Effect of a GnRH injection on kisspeptin levels in girls with suspected precocious puberty: a randomized-controlled pilot study.

Department of Paediatrics, School of Medical Sciences, Faculty of Medicine and Health, Örebro University, Örebro, Sweden.
Objectives: Kisspeptin plays a major role in the onset of puberty by stimulating the gonadotropin-releasing hormone (GnRH) neurons. The aim of this study was to investigate whether GnRH inhibits kisspeptin secretion via a negative feedback mechanism and potential associations between kisspeptin levels and other hormones of importance for pubertal onset.
Methods: Thirteen girls with suspected central precocious puberty underwent a GnRH stimulation test twice in a randomized, placebo-controlled manner.
Diagnostic value of fasting insulin and insulin-like growth factor-1 levels in girls with central precocious puberty.

Objectives: The gonadotropin-releasing hormone (GnRH) provocation test is crucial for diagnosing central precocious puberty (CPP). However, due to its invasion and high cost, it is essential to find a simpler biomarker. This study aimed to investigate the feasibility of fasting insulin (FINS) and insulin-like growth factor-1 (IGF-1) as potential biomarkers for diagnosing girls with CPP and to analyze their effects on puberty development.

Objective: This study analyzed the changes in blood glucose and lipid metabolism levels in children with central precocious puberty (CPP) and the correlation between CPP and obesity.
Methods: In total, 88 children with CPP aged 6-10 years who were admitted to our hospital between January 2023 and June 2024 (the CPP group), and 88 children without CPP in the same age group who received health check-ups (the non-CPP group) were retrospectively enrolled in this study. General data [gender, age, bone age, and body mass index (BMI)] were collected.
