2 Definitions Emphasis on Lifestyle/weight loss Current of evidence of each modality Suggested algorithm/current opinion

3 Rotterdam statement oligo-anovulation - PCO - Hyperandrogenism with the exclusion of CAH, Cushing s, adrenal, Thyroid and Prolactin abnormalities.

4 NIH 90 (oligo-anovulation/high androgens) 06 AES ( NOT PCO + oligo-anovulation)

5 1 st Lifestyle

6 5-10% Weight loss = 80% OVULATION Weight loss pre pregnancy: - decrease GDM - decrease pregnancy complications - miscarriage

7 ovulbin Means sqrtfstg bmi

8 Hurdles: Drop out: Moran 09 = 30-35% Annchen Weideman TBH = 50-60% Diet : - Calorie restriction - GI vs GL - Trans fatty intake

9 Support - spouse - follow up Lifestyle

10 Limit liquid fructose to 20gr/day 3 fruits/day ( 25gr/day) ++ water High quality proteien with meals Exercise Only successful after the 3 rd visit 60% dropout Dietician

11 Bariatric surgery :if all else fail BMI > 40 BMI > 35 with a co morbidity Time to pregnancy! Lifestyle!

13 It is a recommendation of the Rotterdam ESHRE/ASRM consensus meeting that women with PCOS and a BMI in excess of 27 kg/m 2, should undergo a glucose tolerance test and a metabolic screen.

14 Risk factor Cut off 1. Abdominal obesity (waist circumference) >88cm 2. Triglycerides 150mg/dL /1.8mmol/L 3. HDL cholesterol <50mg/dL /<1.3mmol/L 4. Blood pressure 130/85mmHg 5. Fasting and 2-h glucose from oral GTT Fasting glucose mg/dL or 6-7mmol/L, 2-h glucose mg/dL or mmol/L

15 1 st drug of choice? Role of metformin? Role of ovarian drilling? Role of gonadotrophins?

16 Most common drug/1 st line Anti oestrogen/oestrogen receptor Start with the lowest dose: OHSS 25mg 150mg max 80% ovulation rate

17 Monitor EL/ Cx mucous quality Follicle development, day 21 Monitor ovulation with LH levels

18 Aromatase inhibitor Androgens to oestrone/e2 Increases gonadotrophin production NO effect on oestrogen receptors Mono follicle development

19 Biljan 05 (150pt s)?? Cong cardiac/bone abn 05 Novartis: NOT for OI Off-label indication for OI Tulandi and Casper 06 No increase risk 911 babies

20 26 RCT s Not better than ovarian drilling? Improved preg rates vs CC Not good data

21 Inform pt off-label indication/international As effective as CC 2,5mg=7,5mg for mono OI?Use when CC and metformin not successful?use if thin EL and poor mucous on CC

22 1 st drug of choice? Role of metformin? Role of ovarian drilling? Role of gonadotrophins?

24 IS METFORMIN INDICATED AS PRIMARY OVULATION INDUCTION AGENT IN WOMEN WITH PCOS? A SYSTEMATIC REVIEW AND META-ANALYSIS 12

25 Statistically significant difference between the 2 groups, in favour of the combination

26 Significant increase in pregnancy rate in the group of patients treated with the combination (CC+M)

27 No Non-significant difference when the combination was compared to Clomid alone

28 THE EFFICACY OF METFORMIN FOR OVUALTION INDUCTION IN CLOMIPHENE-RESISTANT PCOS WOMEN: A SYSTEMATIC REVIEW 06

30 Not a 1 st line Definitely indicated in CC-resistance Addition to lifestyle to loose weight? With IVF/ICSI: lower OHSS/improve preg rates Current data: stop when pregnant

31 1 st drug of choice? Role of metformin? Role of ovarian drilling? Role of gonadotrophins?

32 RCOG Grade A Guidelines : Women with PCOS who have not responded to clomifene citrate should be offered laparoscopic ovarian drilling because it is as effective as gonadotrophin treatment.

33 No significant differences: laparoscopic ovarian drilling after 6-12m follow-up vs 3-6 cycles of ovulation induction with gonadotrophins in: cumulative pregnancy (OR 1.42; 95% CI 0.84 to 2.42 miscarriage rate (OR 0.61; 95% CI 0.17 to 2.16) Farquhar C, Vandekerckhove P, Lilford R.

37 C/C resistant Drilling as effective as gonadotrophins - ovulation - live birth rates BUT: adhesions/use fine needle/?long term effect/invasive procedure/predictors of success Human Reproduction: 2011

38 1 st drug of choice? Role of metformin? Role of ovarian drilling? Role of gonadotrophins?

39 As effective as drilling NB OHSS/GnRH analogue trigger Low dosage step up protocol Fertility specialist? IVF/ICSI

40 Controversy persists in the diagnosis of PCOS AMH emerges as a marker of the severity of symptoms

41 FERTILITY IN PCOS: OVULATION INDUCTION Lifestyle modification before ovulation induction in obese PCOS cases Clomiphene citrate is still the medical treatment of first choice Aromatase inhibitors are as effective, but more safety data are needed Metformin alone is less effective than clomiphene for inducing ovulation The addition of metformin to clomiphene may be indicated in C/C resistance

42 Gonadotrophins in low-dose protocols aiming for monofollicular development represent an effective treatment option Laparoscopic ovarian drilling is as effective as gonadotrophins for ovulation induction and pregnancy, with lower risk of multiples IVF is a reasonable option,

43 1 st Weight loss Role of metformin 2 nd Clomid/? Femara 3 rd Drilling vs gonadotrophins 4 th IVF/ICSI

44 Myo-inositol is isoform of inositol Role in glucose metabolism Lowering insulin levels Intra cellular activity- better quality oocytes Pre treat: 4gr myo inositol + folic acid (30 days) Future : PRCT metformin vs inofolic

45 Metformin: RJ Norman;Human Reproduction trials, metformin vs placebo Favours metformin 1,5gr for longer than 8weeks Additional 2,9% weight loss, BMI > 35 Orlistat: Padwal 2003 Prevent uptake of lipids in diet: Taken for 1 year 2,9% additional weight loss

46 Sibutramine: Padwal and Makumbar2007 Oral anorexiant; Taken for 1 year 4,6% additional weight loss Taken off most markets- strokes

47 OVULATION INDUCTION IN PCOS: PROSPECTIVE RANDOMIZE CONTROL TRIAL 09

48 Bayar 06 (Femara vs C/C) No difference EL No difference in ovulation/preg Badawy 07 Ideal dose: no difference for mono OI

49 From the scatterplot one can see that all women with BMI <=27 ovulated. Except for two women all women with fasting glucose <(2.2)*(2.2)=4.84 units ovulated. This gives a sensitivity for this simple cutpoints are 66% for ovulation and a specificity of 88% for non-ovulation. Drawing non-linear boundry around the nonovulation group sensitivity can be 78% and specificity 82% which is reasonable for practical use. The number of non-ovulation women is actually so small that the estimates linked (specificity) to this group is not reliable they have to be at least 50 women with unsuccessful ovulation.

54 General advice Lifestyle advice C/C mg Ovulation resistant ADD Metformin If pregnant, -Stop metformin?, not sufficient data Screen for gestational diabetes later in pregnancy Not effective after 6 months Letrozole or earlier Consider ovarian drilling Consider assisted conception New, immature aspiration

55 53 % Reduction in Ovulation when Metformin was used compared to Clomid alone

56 53 % Reduction in LBR in the group treated only with Metformin

57 PCOS most common endocrinopathy 5-10% of reproductive age Etiology remains unclear/ INSULIN Definitions

58 This leaves one with the question of how much weight loss should be aimed for. Hollmann et al. as well as Clark and co-workers, proved that only a small amount of weight loss is needed for resumption of ovulatory function. 2 5 % reduction of body weight was associated with restoration of ovarian function, an 11 % reduction of abdominal fat, a 4 cm waist circumference reduction and the added benefit of a 71% increase in insulin sensitivity. Diabetic prevention trial: metformin vs lifestyle

(sugar & starch) Similar incidence in all PCOS Central weight gain Hypoglycaemia More

59 Herriot et al. (2008) Subjective, debilitating symptoms Understanding symptom profile : CHO cravings (sugar & starch) Similar incidence in all PCOS Central weight gain Hypoglycaemia More frequent in lean General lethargy/chronic fatigue 82 % of all PCOS Urgent sense of hunger IBS/food intolerance 68 % all PCO Symptoms improved with lowered glycaemic load

60 betref is daar ook n persepsie dat one size fits all wat versterk is deur die media wat so baie crap oor dieët en gewigsverlies sensasionaliseer. 3. Oorgewig PCOS pasiënte toon duidelike versteurings in honger en versadigings-cues (mooi beskryf in die literatuur), sodat kalorie-beperking vir hulle eintlik pynlik is om te verdra, en hulle is bang daarvoor. a. Derhalwe my spesifieke riglyne van proteïen-insluiting ens. b. GI is nog nooit gewys om enige utility in PCOS te hê nie, alhoewel daar n wydverspreide geloof bestaan dat PCOS lyers dadelik op n lae GI dieët moet gaan. Dit lei tot verhoogde koolhidraat-inname met swak prognose vir verbetering van insulienweerstandigheid. GL (glycaemic load) is waarskynlik die belangrikste aspek om aan te spreek, op n individuele basis. 4. Die pasiënte wat die beste doen is die wat onbevooroordeeld is, en die ondersteuning van hulle spouses het
