Insights
Precocious pubarche in young Thai children is often caused by congenital adrenal hyperplasia (CAH). Early investigation is crucial to identify underlying pathological causes like CAH.
Area of Science:
- Pediatric Endocrinology
- Reproductive Health
- Endocrine Disorders
Background:
- Precocious pubarche, the early development of pubic hair, requires thorough evaluation in children.
- Understanding the diverse etiologies is essential for appropriate diagnosis and management.
Purpose of the Study:
- To investigate the causes, clinical features, and laboratory findings in young Thai children presenting with precocious pubarche.
- To determine the prevalence of different etiologies and identify key diagnostic markers.
Main Methods:
- Retrospective review of medical records for 41 children evaluated for precocious pubarche between 1995 and 2011.
- Analysis of clinical data, anthropometric measurements, and hormonal assays.
Main Results:
- Congenital adrenal hyperplasia (CAH) was the most frequent etiology (46.3%), followed by isolated premature adrenarche (29.3%).
- Pathological etiologies were associated with significantly greater weight and height compared to isolated premature adrenarche.
- Elevated 17-hydroxyprogesterone levels indicated CAH, while higher DHEAS levels suggested adrenocortical carcinoma.
Conclusions:
- Precocious pubarche in Thai children warrants investigation for underlying pathological conditions.
- Congenital adrenal hyperplasia is the predominant pathological cause requiring prompt diagnosis and treatment.
Objective:
To describe the etiologies, clinical characteristics, and laboratory investigations of young Thai children being evaluated for precocious pubarche.
Material And Method:
The medical records of 41 children referred for evaluation of precocious presence of pubic hair at Songklanagarind Hospital between 1995 and 2011 were retrospectively reviewed.
Results:
The etiologies of precocious pubarche in young Thai children were congenital adrenal hyperplasia (n = 19, 46.3%), isolated premature adrenarche without pathology (n = 12, 29.3%), hypothalamic hamartoma (n = 7, 17.1%), adrenocortical carcinoma (n = 2, 4.9%), and Leydig cell tumor (n = 1, 2.4%). The weight and height of patients with pathological etiologies were significantly greater than those with isolated premature adrenarche (p < 0.001). Patients with congenital adrenal hyperplasia had significantly greater levels of basal and peak 17-hydroxyprogesterone than those with isolated premature adrenarche (p < 0.001). Patients with adrenocortical carcinoma had significantly greater level of DHEAS than those with congenital adrenal hyperplasia and isolated premature adrenarche (p < 0.001).
Conclusion:
The precocious presence of pubic hair in young Thai children should be investigated for an underlying pathological etiology. The most common underlying pathology of precocious presence of pubic hair is congenital adrenal hyperplasia.
