Over premature pubarche Kinderen die te vroeg schaamhaar (pubisbeharing) krijgen, hebben last van premature pubarche. We noemen deze beharing te vroeg als jongens het vóór hun negende krijgen en meisjes voor hun achtste. Ook kunnen kinderen met premature pubarche last hebben van okselbeharing, volwassen transpiratiegeur en acné.

Premature pubarche (PP) in girls is considered to be a benign phenomenon and is the clinical expression of premature adrenarche. Since it does not usually increase the risk of either abnormalities in pubertal development or a reduced final adult height, a non-interventional approach is generally adopted after exclusion of non-classical (NC)congenital adrenal hyperplasia (CAH).

31 - 33 Premature Adrenarche; Delayed puberty; Gonadarche; Lina Medina, who had her menarche at age 8 months and is the youngest mother in history; Menopause, the equivalent opposite change at the end of the child-bearing years; Pubarche; Spermarche; Thelarche; References Premature adrenarche (PA) is one of the most common diagnoses made in children referred to a specialist for signs of early puberty. Key features of premature adrenarche. Appearance of pubic and/or underarm hair in girls younger than 8 years or boys younger than 9 years; Adult-type underarm odor, often requiring use of deodorants The data collection ended in January 2016. Adrenarche was assessed by serum DHEAS levels and pubertal status by Tanner stages. Pubarche was defined as the appearance of pubic hair (PH2), whereas spontaneous puberty was defined as Tanner stage B2. Adrenarche, which typically precedes gonadarche, is associated with increased secretion of adrenal androgens and leads to the appearance of sexual hair (pubarche). The major adrenal bioactive C19 androgens are dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), and androstenedione. Data on adrenarche and pubarche in girls with Turner syndrome (TS) are inconsistent in the literature.

Pubarche vs adrenarche

1995-05-01 Precocious pubarche: distinguishing late-onset congenital adrenal hyperplasia from premature adrenarche. Armengaud JB, Charkaluk ML, Trivin C, Tardy V, Bréart G, Brauner R, Chalumeau M J Clin Endocrinol Metab 2009 Aug;94(8):2835-40. 2012-03-25 Condition in which there is early onset of pubic hair (pubarche) and/or body odor that occurs before age 8 years in girls and before age 9 years in boys No true pubertal development (ie, no breast development in girls, no testicular growth in boys), nor evidence of clitoromegaly or penile growth in idiopathic premature pubarche or premature adrenarche 2019-10-11 The ‘exaggerated adrenarche’ group had higher 17 OHPreg/17OHP ratios at 60 minutes after stimulation but these were not diagnostic for 3β‐HSD deficiency. CONCLUSION The value of assessing basal steroids in children presenting with premature adrenarche Is demonstrated in this series with 5·7% being diagnosed with 21‐hydroxyiase deficiency and 9·1% with ‘exaggerated adrenarche’.

Pubarche appeared before 10.0 years in <2% of normal-BMI boys. Girls with excessive BMI had a significantly higher prevalence of breast appearance from ages 8.0 through 9.6 years and pubarche from ages 8.0 through 10.2 years than those with normal BMI. Menarche was also significantly more likely to occur in preteen girls with an elevated BMI. Adrenarche is a lot like puberty; it’s characterized by changes in the body as your child enters her teen years.

Adrenarche, which typically precedes gonadarche, is associated with increased secretion of adrenal androgens and leads to the appearance of sexual hair (pubarche). The major adrenal bioactive C19 androgens are dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), and androstenedione.

The reason why this increase occurs earlier in some children is not known. We do know that being overweight increases a child’s chances of having PA, but many children with PA are not overweight. Precocious pubarche (PP) is defined as pubic hair onset before age 8 in girls and age 9 in boys (1– 5). In 80 to 95% of cases, PP is related to premature adrenarche (PA), the nonpathological precocious secretion of adrenal androgens ( 6 , 7 ).

Previous reports claim that pubarche should not necessarily present true puberty in a considerable number of boys older than 10 years of age with normal development. Indeed, it seems that in most cases, the presentation of isolated pubarche is to be the consequence of isolated adrenarche.

This is a self-limited condition occurring before six years of age that is characterized by the appearance of pubic and, occasionally, axillary hair, increased Adrenarche is a separate developmental stage that typically takes place at least two years before puberty itself, according to George Patton, consultant child and adolescent psychiatrist professor Despite high DHEAS levels, pubarche was delayed in the POF group compared with the Turner syndrome girls with spontaneous puberty onset. Pubarche occurred more than 4.5 yr after adrenarche at a median age of 13.0 yr (P = 0.02; Fig. 2). In contrast, the spontaneous puberty group exhibited pubarche 1.4 yr after adrenarche at a median age of 11.9 yr.
