Shin-Hye Kim, Ju-Yeon Moon, Hironobu Sasano, Man Ho Choi, Mi-Jung Park
CONTEXT: Pediatric obesity has been related to hyperandrogenism and premature adrenarche in previous studies. However, little is known regarding the association between body fat mass and steroidogenic enzyme activities in children. OBJECTIVE: To examine whether body fat mass is associated with serum steroid profiles in girls. DESIGN, PARTICIPANTS, AND SETTING: We enrolled 242 girls (125 prepubertal, 117 pubertal; aged 7-13 years). Early morning blood samples were drawn at a university hospital to measure serum steroid profiles using gas chromatography-mass spectrometry, and steroidogenic enzyme activities were assessed from the ratios of steroid metabolites...

This Consensus Statement summarizes recommendations for clinical diagnosis, investigation and management of patients with Silver-Russell syndrome (SRS), an imprinting disorder that causes prenatal and postnatal growth retardation. Considerable overlap exists between the care of individuals born small for gestational age and those with SRS. However, many specific management issues exist and evidence from controlled trials remains limited. SRS is primarily a clinical diagnosis; however, molecular testing enables confirmation of the clinical diagnosis and defines the subtype...

BACKGROUND: Current clinical practice is to evaluate children presenting with premature adrenarche (PA) for non-classical congenital adrenal hyperplasia (NC-CAH). Our main objective was to assess the prevalence of NC-CAH among children presented with PA. Additional objectives were to ascertain whether subpopulations were prone to NC-CAH, and therefore justified to be tested, and if obesity is a factor that can exclude the need for CAH testing. METHODS: A retrospective chart review of all children ≤11 years, who presented to our clinic with PA between January 2012 and May 2015 (n=103) was conducted...

The normal function of the female reproductive system is closely linked to energy homeostasis with the ultimate scope of fertility and human race perpetuation through the centuries. During a woman's lifetime there are normal events such as puberty, pregnancy and menopause which are related to alterations in energy homeostasis and gonadal steroids levels followed by increase of body fat and insulin resistance, important components of metabolic syndrome (MetS). Pathological conditions such as premature adrenarche, polycystic ovary syndrome and gestational diabetes also present with shifts in gonadal steroid levels and reduced insulin sensitivity...

Polycystic ovary syndrome (PCOS) is a multifactorial disorder that arises from interactions between genetic, environmental and intra-uterine factors. Small-for-gestational-age (SGA) babies and the daughters of mothers with PCOS represent possible postnatal clinical targets for developmental programming by steroid excess. The presence of excess glucocorticoids and/or androgens during foetal organogenesis and growth might promote changes in gene expression, and these changes might be related to an increase in the risk of PCOS-like reproductive and metabolic disorders in postnatal life, such as rapid growth and weight gain during the first 2 years of life (only in SGA babies), hyperinsulinaemia, adipocyte dysfunction and childhood visceral obesity, premature pubarche and adrenarche (only in SGA babies) and PCOS...

OBJECTIVE: Idiopathic premature adrenarche (PA) refers to presence of androgenic signs before the age of eight years in girls in the absence of thelarche. In children with PA, increased adrenal androgens lead to changes in body composition and transient growth acceleration. Although the association between PA and some components of the metabolic syndrome is well known, body composition has not been extensively studied in these patients. METHODS: We examined 47 girls with PA with a median age of 7...

BACKGROUND: Concerns about psychological distress are often used to justify treatment of girls with precocious puberty, but there is little evidence to support these concerns. The extent to which psychological problems are associated with central precocious puberty (CPP) compared with other forms of early puberty in girls has likewise not been established. METHODS: Girls presenting with untreated CPP, premature adrenarche (PA) or early normal puberty (ENP) were recruited from our pediatric endocrine clinic along with their mothers...

Adrenarche refers to a maturational increase in the secretion of adrenal androgen precursors, mainly dehydroepiandrosterone (DHEA) and its sulfate (DHEAS). In premature adrenarche (PA), clinical signs of androgen action appear before the age of 8/9 years in girls/boys, concurrently with the circulating DHEA(S) concentrations above the usually low prepubertal level. The most pronounced sign of PA is the appearance of pubic/axillary hair, but also other signs of androgen effect (adult type body odor, acne/comedones, greasy hair, accelerated statural growth) are important to recognize...

A single enzyme, microsomal P450c17, catalyzes the 17α-hydroxylase activity needed to make cortisol and the subsequent 17,20 lyase activity needed to produce the 19-carbon precursors of sex steroids. The biochemical decision concerning whether P450c17 stops after 17α-hydroxylation or proceeds to 17,20 lyase activity is largely dependent on three post-translational factors. First, 17,20 lyase activity is especially sensitive to the molar abundance of the electron-transfer protein P450 oxidoreductase (POR)...

CONTEXT: Adrenarche refers to the onset of increased production of adrenal androgens in childhood leading variably to clinical signs of androgen action. The prevalence and presentation of adrenarche in prepubertal girls and boys is not well known. OBJECTIVE: Our objective was to examine the prevalence and clinical presentation of adrenarche in a population sample of prepubertal children aged less than 9 years. DESIGN AND PARTICIPANTS: This cross-sectional study included prepubertal children (209 girls and 228 boys; median age 7...

Adrenarche means the morphological and functional change of the adrenal cortex leading to increasing production of adrenal androgen precursors (AAPs) in mid childhood, typically at around 5-8 years of age in humans. The AAPs dehydroepiandrosterone (DHEA) and its sulfate conjugate (DHEAS) are the best serum markers of adrenal androgen (AA) secretion and adrenarche. Normal ACTH secretion and action are needed for adrenarche, but additional inherent and exogenous factors regulate AA secretion. Inter-individual variation in the timing of adrenarche and serum concentrations of DHEA(S) in adolescence and adulthood are remarkable...

BACKGROUND: Clinical findings in children with premature adrenarche (PA) correlate only partly with circulating levels of adrenal androgens. It is not known whether the prepubertal low circulating concentrations of testosterone (T) and dihydrotestosterone, together with those of adrenal androgens, are capable of activating the androgen receptor. METHODS: This cross-sectional study was performed at a university hospital. Circulating androgen bioactivity was measured in 67 prepubertal children with clinical signs of PA and 94 control children using a novel androgen bioassay...

Acne vulgaris in infants and children often triggers extensive laboratory evaluation out of concern about associated endocrinopathy. Clinical parameters to help guide evaluation of these children have not been defined. This was a retrospective chart review of 24 preadolescent patients with acne and a review of related medical literature. Two age-related subsets were identified: 12 patients who developed acne before the age of 15 months, 75% male, with comedonal and inflammatory lesions; and 12 patients who developed acne between the ages of 2 and 7 years, 75% female, with primarily comedonal lesions...
