Conflict of Interest PCOS across the Lifespan: An Update on - PowerPoint PPT Presentation

10/24/2014 Conflict of Interest PCOS across the Lifespan: An Update on Treatment • Financial conflict – none Strategies • Research conflict – Funded research: • Ferring Pharmaceutical • Nora Therapeutics • Off –label drug use Marcelle I. Cedars, M.D. – none University of California – San Francisco PCOS: Overview PCOS across the lifespan � Characterized by oligo-ovulation, hirsutism, polycystic ovaries Young Adult Reproductive Age Post Reproductive � 5-10% Reproductive age females � Pathogenesis unclear: - Androgen Diagnosis Fertility - Insulin - Pituitary Management of Symptoms: Cycle Control Hirsutism � Familial clustering: genetic etiology ? Metabolic Alterations 1

10/24/2014 Young Adult PCOS: Diagnosis Rotterdam Criteria Must have at least 2 out of 3: Making the PCOS Diagnosis 1. Oligo- or anovulation 2. Clinical and/or laboratory evidence of hyperandrogenism 3. Polycystic ovaries Exclusion of other etiologies PCOS Diagnosis: Anovulation PCOS Diagnosis: Hyperandrogenism Anovulation Clinical Evidence Lab Evidence Oligo-anovulation • Hirsutism Total Testosterone 1. Less than 8 periods/year • Acne Free Testosterone 2. Variable bleeding pattern • Male pattern DHEA-S 3. Amenorrhea rare alopecia 4. Unopposed estrogen increases risk 2

10/24/2014 PCOS Diagnosis: Ovary Controversy: Follicle Number • Specificity concerns: Ovary Criteria: Follicle cut off of 12 is too low • 12 or more follicles measuring 2-9 mm in • Relevance concerns: diameter Follicle count does not • Increased ovarian associate with metabolic volume (>10cm 3 ) abnormalities Rotterdam Criteria for Polycystic Controversy: Follicle Number Ovary Syndrome (PCOS) • Specificity concerns: Percentage Meeting Rotterdam Criteria, by Age 70 Follicle cut off of 12 is too 62.5 60 AFC >12 in one ovary low Percentage 50 40 34.48 • Relevance concerns: 30 24.69 Follicle count does not 20 6.82 associate with metabolic 10 abnormalities 0 25-30 31-35 36-40 41-45 (n= 48) (n = 88) (n = 84) (n = 45) Age group Modified from Johnstone 2010 3

10/24/2014 Metabolic Impact of Isolated PCO Young Adult -> Reproductive Age • Cycle control and uterine protection • Hirsutism • Acne Johnstone 2010 Management: Uterine Protection Mechanism of OCP ocp o Protect the uterus • Unopposed estrogen = Estrogen o Increase SHBG risk of hyperplasia Pituitary o Inhibit of LH secretion adrenal liver o Inhibit adrenal DHEAS • Options for protection: androgen secretion SHBG LH . Progestin 1. Cyclical Progestin Estrogen 2. Combined contraceptive uterus ovary Testosterone 3. Mirena IUD 4
