Case A

14 y/o female (menarche 1 yr back)• Menses q 3--4 months• Mild facial acne• FG Score of 5 (1 lip, 1 chin, 2 lower abd, 1 back)• BMI 29 kg/m2• No galactorrhoea


• What are the various causes of hyperandrogenism?

• In this adolescent girl what probable cause do you suspect?


Aetiology of hyperandrogenism

• FOH of puberty• PCOS• HAIR-AN syndrome• Hyperprolactinemia• Hypothyroidism• NCAH• TUMORS-Ovarian / Adrenal• Cushings disease• Drugs


• What particular aspects of history & clinical features would you like to look for?


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


What is this C/F?

•Would you like to investigate this patient at this juncture?


• Would you like to start treatment at this time?

• In which particular patients would you evaluate & treat at an early age?

Insulin sensitization early after menarche prevents progression from precocious pubarche to polycystic ovary syndrome in a high-risk group of formerly LBW girls.


LIFESTYLE MODIFICATIONS


Adult v/s Adolescent HA

•FOH or Organic cause???•USG not reliable-ovaries may

be N.•Premature adrenarche –strong

predictor.•Lifestyle changes – biggest

impact-Prevention of PCOD !!!

• Same patient comes to you after 2 yrs (age 16 yrs) - still having same clinical picture but worsened

delayed periods mod. acne & hirsutism BMI 32


• Would you like to evaluate this patient now?

• What initial screening investigations would you like to go for & why?


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 T?? Should we ask for? – no clinical need to check - if HA effect seen then free T must be raised - does not help in D/D or

treatment


• 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


Audience question• Would you like to

include S.DHEAS in her list of investigations?

If YES - WHY? If NO – WHY NOT?


DHEAS ???

• Moderate elevation common in anovulatory females

• > 700 micgm/dl – v.rare• if T> 200 – screen for tumor must• Mod. elevated DHEAS does not

necessitate or prove the need & benefit of treatment with dexamethasone

• No further benefit by testing,not cost effective

Gordon,Speroff 2002


Lab resultsof this patient

TSH, Prolactin, 17OH P : normal Total T : 70 ng/mL [<72 ng/mL] Fasting Insulin : 22 mIU/mL [<20 mIU/mL] Fasting Glucose 92 mg/dL


• What are the options available for treating HA?


COCPs

ANTIANDROGENSSPIRONOLACTONE

FUTAMIDEFINASTERIDE

CYPROTERONEDEXAMETHASONEKETOCONAZOLE

CIMETEDINEGnRH AGONISTS

INSULIN SENSITIZERSMECHANICAL AGENTS(hirsutism)

ANTIBIOTICS (acne)


• Considering our diagnosis of PCOS in this girl what are your aims of treatment

• What treatment would you like to start in this patient?

• How long should you continue with this treatment?


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


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.

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.

AUDIENCE QUESTION

WHICH PILL WOULD YOU CHOOSE FOR ADOLESCENT PCOS with HA & WHY?

• LNG containing (mala-D,ovral-L,Loette)• DESOGESTREL containing (novelon,femilon)• CYPROTERONE containing (Ginette,krimson35, diane35)• DROSPIRINONE containing (yasmin)


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 ( VENOUS THROMBOEMBOLISM & LIVER )

INITIAL SCREENING ??35Dr Mona Shroff

www.obgyntoday.info

Lab results

• TSH,, Prolactin normal• 17OH P : 2.5 ng/mL [<2 ng/mL]• Total T : 70 ng/mL [<72 ng/mL]• Fasting Insulin 14 mIU/mL [<17 mIU/mL]• Fasting Glucose 92 mg/dL

What would you do next?36Dr Mona Shroff

www.obgyntoday.info

ACTH Stimulation Test

Baseline 17 OH P 2..5 ng/dL 60 min 17 OH P 18 ng/dL

What is your inference? How would you treat this patient?


•Treat hyperandrogenism with dexamethasone or CPA or spironolactone or flutamide• Treat irregular menses with combined oral contraceptive pills• Treat infertility when patient desires pregnancy• Consider adding dexamethasone to ovulation induction


NCAHJ Clin Endocrinol Metab. 1990 Mar;70(3):642-6.

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.

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.
