Mild symptoms of hyperandrogenism are
common in adolescents
•
•
Hirsutism – 6%
Acne – 36-98% in western countries

• Additionally
:: These HA symptoms may
be associated with irregular menstrual
cycles.
•Three years post menarche 20 -40%
cycles are irregular (Physiological HA of
Puberty).

• .... In some girls These features
persist and even make worse..
Subjects with persistent symptoms of
hyperandrogenism
Most frequently associated with PCOS
But another etiologies must be ruled
out.
Clinicians main aim should be to
• Establish an early PCOS diagnosis.
• Rule out Adrenal/Ovarian Tumor & NCAH
This presentaton includes
• Aetiology of HA
• Approach to an adolescent with HA
- Important clinical features to look for
-the optimum necessary Ix
-Evidence based best possible Rx protocol
• Case studies
Adult v/s Adolescent HA

FOH or Organic cause???
USG not reliable-ovaries may be N.
Premature adrenarche –strong predictor.
Long term Rx-choose drugs with min.
lipid & metabolic S/E.
• Lifestyle changes – biggest impactPrevention of PCOD !!!

Aetiology of
hyperandrogenism
•

PCOS
HAIR-AN syndrome
Hyperprolactinemia
Hypothyroidism
NCAH
TUMORS-Ovarian / Adrenal

Hirsutism
Alopecia
Android obesity
Menstrual dysfunction
Infertility
Cardiovascular disease
Dyslipidemia
Glucose intolerance/insulin
resistance/T2NIDDM
• Hypertension
Signs of
Virilization
• Acne
• Hirsutism
• Clitoromegaly
• Deepening of voice
• Increased libido
• Increased muscle mass
(primarily shoulder girdle)
• Infrequent or absent
menses
• Loss of breast tissue or
normal female body
contour
• Malodorous perspiration
• Temporal hair recession
and balding
Diagnosis of HA in Female
Adolescents
1. Clinical assessment
2. Laboratory screening
3. Further investigations
Clinical assessment
History
The following items are important::
Family History of
HA/Obesity/temporal balding/infertility
• Hx of Precocious adrenarche
• More than 2 years of oligomenorrhea
•
Clinical assessment..
Physical examination
• Degree of hirsutism, acne
• Obesity ,increased W/H ratio
Acanthosis nigricans- r/o PCOS,HAIR-AN
• Rapidly growing hirsutism or
Virilizing symptoms – r/o TUMOR
• Symptoms of hypercorticism –r/o CUSHING
• Galactorrhea – r/o HYPERPROLACTINEMIA
Age-related changes in the
PCOS phenotype
Reproductive abnormalities
Clinical hyperandrogenism
Metabolic abnormalities
Adolescence
Adult fertile age
Menopause
Postmenopause
INITIAL LAB
SCREENING
•
•
•
•
•
TESTOSTERONE
PROACTIN
TSH
Evaluation for HYPERINSULINEMIA
17 OH PROGESTERONE
INITIAL LAB
SCREENING
• Testosterone
total – may be N in hirsute woman
if T> 200 screen for tumor
free – no clinical need to check
if HA effect seen then
free T must be raised
• TSH - esp if alopecia
• PROLACTIN DHEAS ,free T
(SHBG )
• HYPERINSULINEMIA
Fasting glucose : Insulin < 4.5
Fasting insulin > 20
2 hr GTT > 140
• 17 OH P
- for NCAH , follicular ph/morning
-routine screen in HA indicated
(esp if sev hirsutism at younger
age ,short stature)
* <200 ng/dl : N
* 200 – 800 : ACTH stimulation test
* > 800 : diagnostic
• Screen for Cushings if clinical suspicion
late eve. plasma cortisol
single dose overnight DST
• Imaging of adrenals & ovaries
(USG/CT/MRI)
* if rapid virilization
* T > 200 micgm/ dl
DHEAS ???
• Moderate elevation common in
anovulatory females
• > 700 micgm/dl – v.rare
• if T> 200 – screen for tumor must
• No further benefit by testing,not
cost effective

ANTIANDROGENS
COCPs
GnRH AGONISTS
MECHANICAL AGENTS(hirsutism)
ANTIBIOTICS (acne)
SPIRONOLACTONE
FUTAMIDE
FINASTERIDE
CYPROTERONE
DEXAMETHASONE
KETOCONAZOLE
CIMETEDINE
INSULIN SENSITIZERS
Management of excess ovarian androgen
production :
Standard therapy is :combined E+P
OCs
• It reduces ovarian androgen
production
• It increases SHBG
• It induces competition at the
cellular level for binding to the
androgen receptor
COCs
LNG vs Desogestrel vs CPA
• DSG & CPA pills comparable efficacy, better
than LNG.(CPA slightly better for acne)
• DSG & CPA pills comparable side effects

ANTIANDROGENS
• According to currenty available
evidence no antiandrogen is
superior to other in terms of
clinical efficacy, so choice
depends upon S/E & cost.Further
studies needed.

METFORMIN
• In addition to the expected improvements
in insulin sensitivity and glucose metabolism
• Ameliorates hyperandrogenism and menstrual
irregularity.
• Reduces total cholesterol, LDL and
triglycerides of PCOS adolescents while
increasing HDL cholesterol .
• Decrease C-reactive protein and a
normalization of the neutrophil/lymphocyte
ratio , which are predictive of cardiovascular
disease.
Benefits both obese & non obese

Cyproterone acetate versus hydrocortisone treatment in
late-onset adrenal hyperplasia.
• Peripheral antiandrogen therapy may be
more appropriate in late-onset adrenal
hyperplasia patients than conventional
adrenal inhibition using cortisone
therapy.
TUMOUR
SURGICAL REMOVAL
CONCLUSIONS
• HA is a common adolescent probem
• Our main aim is early PCOS diagnosis & ruling
out tumor/NCAH.
• Watch for premature pubarche.
• Initial screen –T, TSH, Prolactin, fasting
glucose:insulin, 17 OH P
• Imaging for tumor if T>200 or rapid
virilisation
CONCLUSIONS (contd.)
• Lifestye modification & weight
reduction plays a key role.
• Integrated approach – combination of
drugs with best outcome & min. S/E.
(COCs + IS + Antiandrogen).
• PCOS - Candidates for long term
therapy.
