PCOS and contraception
Prof Helle Karro Antalya, 2017

PCOS Heterogeneous endocrine disorder, a lifelong syndrome, beginning in the prenatal period with manifestations in childhood, adolescence and adulthood Multifaceted disease involving uncontrolled ovarian steroidogenesis, aberrant insulin signalling, excessive oxydative stress and genetic/environmental factors Hayek et al, Frontiers in Physiology, 2016 Highly prevalent diorder which affects multiple aspects of womens general health Multiple studies suggesting that might start in utero, mainly in neonates with risk factors for PCOS. LBW and high BW, who later catch-up on their growth or constantly increase in weight postnatally. Such factors+ genetic disposation - premature pubarche, adrenarche and later metabolic syndrome

PCOS and associated morbidities
Obesity Childhood obesity as a risk factor for PCOS Pascali et al, 2011 One of the most important features of PCOS Prevalence varies between 61%-76% Glueck et al,2005 Insulin resistance Hyperinsulinemia is present in 85% of PCOS patients, incl 95% of obese and 65% of lean women Teede et al 2010, 2011; Stepto et al, 2013 Type II Diabetes Mellitus 1 in 5 women with PCOS will develop DM2 Dunaiff, 1999 Increased risk for gestational diabetes Boomsma, 2006 Increased risk for DM2 Moran, 2011

PCOS and associated morbidities
Cardiovascular disease Several studies have shown significantly elevated levels of biomarkers, incl C reactive protein and lipoprotein Bahceci, 2004, 2007; Meyer 2005; Yilmaz, 2005; Berneis, 2009, Rizzo, 2009 Early cardiovascular dysfunction (arterial stiffness, endotelial dysfunction, coronary artery calcification Meyer, 2005; Moran, 2009 There is discrepancy between studies determining the absolute risk of CVD in patients with PCOS El Hayek, 2016 Infertility Psychological wellbeing

PCOS and associated morbidities
Cancer Endometrial cancer Many acssociated risk factors – obesity, insulin resistance, DM2, anovulation Legro, 2013 Women with PCOS have three times higher risk compared to controls Chittenden, 2009; Fauser, 2012, Haoula, 2012; Dumesic and Lobo, 2013 Ovarian cancer Contradictory evidence exists between PCOS and risk of ov cancer Schildkraut, 1996; Balen, 2001; Dumesic and Lobo, 2013 Breast cancer Limited data to support association between PCOS and breast ca Fauser, 2012; Dumesic and Lobo, 2013; El Hayek, 2016

Criteria for the diagnosis of PCOS
NIH/NICHD, 1990 Dgn :including all of the following (two of two) ESHRE/ASRM (Rotterdam criteria, 2003 Dgn: includes two of three AES definitsioon, 2006 Dgn: including all of the following (two of two) Oligo/anovulation Ovulatory dysfunction Ovarian dysfunction and/or polycystic ovarian morphology (PCOM) Clinical and/or biochemical signs of hyperandrogenism Polycystic ovarian morphology (PCOM) Exlusion of other androgen exess or other related disorders NIH-National Institute of Health; Rotterdam – consensus workshop (ESHRE, ASRM); AES – Androgen Exess Society
7
Classification of PCOS phenotypes
Phenotype A Phenotype B Phenotype C Phenotype D Hyperandrogenism and hirsutism + - Ovulatory dysfunction Polycystic ovarian morphology 1990 NIH criteria 2006 AE-PCOS criteria 2003 Rotterdam criteria Daria Lizneva, 2016: NIH consensus workshop suggested in 2012 to use 4 PCOS phenotypes. Tabel summarizes these phenotypes and their relationship to the current criteria Phenotypic approach is convienent for epidemiological research and clinical practise It would be helpful to identify those women with PCOS who are at highest risk for metabolic dysfunction – classic PCOS phenotypes A and B NIH, 2012
11
Hormonal contraceptives use in PCOS
Combined hormonal contraceptives Noncontraceptive use Risks versus benefits Hormonal contraceptive choice
12
Oral contraceptive pills and PCOS
Most commonly used medications have been recommended by the task Force and Endocrine Society (Legro, 2013), the Australian alliance (Misso, 2014) and the PCOS consensus group (Fauser, 2012) as the first-line treatment for the hyperandrogenism and menstrual irregularities However, PCOS is associated with different comorbidities, and assesment for individual risk factors is needed (risks versus benefits) Dokras, 2016
13
Screening for contraindications
Hormonal contraception is recommended as first-line managment for the menstrual abnormalities, hirsutism/acne Screening for contraindications For women with PCOS one formulation is not better than other For adolescent girls: HC as a first-line treatment and/or contraception when PCOS is suspected In addition life style therapy; metformin for IGT/metabolic syndrome Premenarcheal girls ( >=Tanner 4), HC
14
Oral contraceptive pills (OCP), mechanism of action
supression of the HT-HF-ov axis, OCP decreases LH, increases SHBG and decreases free androgens decreases adrenal androgens secretion and inhibition of periferial conversion of testosterone to dihydrotestosteron Improvement in symptoms such as menstrual irregularities, clinical signs of hyperandrogenism and effective contraception
18
PCOS phenotypes: hormonal contraceptive choice
There are no clinical guidelines that recommend a specific CHC for the different phenotypes, there are doubts concerning metabolic and cardiovascular effect Ideal contraceptive should limit follicular development to reduce androgen synthesis, block the peripheral action of androgenes, assure good menstrual cycle control and minimal metabolic or thromboembolic risk Mendoza et al. Gynecological endocrinology, 2014
19
PCOS phenotypes: hormonal contraceptive choice
HA/PCOS CHC (oral, patch or vaginal ring) as first-line treatment, but there are insufficient data to define the optimal treatment For the androgen excess, the most important parameter for the CHC selection is the type pf progestin with antiandrogen activity; studies on the efficacy of CHC containing DRSP or CPA in the treatment of hirsutism, show a reduction of clinical manifestation of HA after 6-12 months There are no data providing direct comparisons reagrding the type or dose of estrogens; lowest effective estrogen dose should be used Research has shown 2–fold increased risk in the VTE among women with PCOS who take CHC and 1,5–fold increased risk among PCOS women not taking CHC Bird, 2013 Few studies comparing EE doses; E2V/DNG seems to be more favorable than EE/LNG on prothrombin, D-dimer, HDL, LDL, insulin and carbohydrate metbolism Fruzetti, 2012 Extended regimes improve follicular control and hormonal supression better Kallio, 2013 Mendoza et al. Gynecological endocrinology, 2014
20
PCOS phenotypes: hormonal contraceptive choice
PCOS/metabolic risk or obesity Few studies have focused on the possible differences in the effect of CHC lean vs obese women; in lean adverse effect on adiposity, insulin sensitivity/glycose tolerance status and lipid profile are not expressed In three meta-analyses the use of CHC was not associated with clinically significant adverse metabolic consequences Costello, 2007; Jing, 2008; Halperin, 2011 When arterial hypertension or elevated risk of VTE is present, LngIUS or progestagen-only hormonal contraception should be used instead of CHC WHO MEC Combination with DRSP could be more advantageous in overweight women whose glycose tolerance is in concern Low-dose oral CHC is preferable in patients with glycose intolerance or IR Verhaeghe, 2010 A vaginal contraceptive ring appears to be preferred to oral EE/DRSP Mendoza et al. Gynecological endocrinology, 2014
24
Morbidity of PCOS patients regarding several diseases is significantly increased
Treatment with life-style modification and metformin could be important tools for the prevention of adverse disease outcomes; OC could be both, benefit and harm Individual risks should be considered
25
Conclusive remarks PSOS patients contraceptive needs should be discussed CHC remains an option for PCOS patients However individual risk/benefit ratio has to be considered and tailored treatment recommended Interdisciplinary approach and follow-up should be offered, taking into account the life curve of the patient
