Objectives S After this lecture, the healthcare provider should be able to S Use the “new” classification system developed by the FIGO Menstrual Disorders Working Group to describe the symptoms and etiologies related to abnormal uterine bleeding (AUB) S Identify management options for abnormal uterine bleeding S Critically evaluate medical and surgical therapies for Abnormal Uterine Bleeding and their associate anomalies as well as those not caused by structural abnormalities or systemic etiologies

Prevalence S Abnormal Uterine Bleeding S Alterations in the volume, amount or pattern of menstrual bleeding or blood flow S Estimated that AUB can affect 10%-35% of women S Most common group of gynecological disorders for which women seek care S Approximately 5%-10^ of women of reproductive age seek medical care for heavy bleeding Oceans Womb by Ciska Maie et al 1990 Prentice et al 1999, Lui et al 2007

Why do we care about AUB? Women with AUB are less likely to quantify their health as excellent or good Women with significant AUB work an average of 3. 6 weeks less per year than women without AUB Average work loss from heavy bleeding is estimated to be $1692 per woman Estimated total direct cost AUB $1 -1. 55 billion annually Menorrhagia Healing by Barbara Bruch Costs et al 2002, Cote et al 2003, Liu et al 2007

Confusing definitions S The Menstrual Disorders Working Group FIGO developed a nomenclature and classification system to describe the symptoms and etiologies of AUB S Approved by the FIGO executive board and supported by ACOG S Simple symptom descriptions S Classification system for etiologies Fraser and Sungurtekin 2000; Fraser et al 2007, Munro et al 2011

Confusing definitions Time for clarification… S Heavy Menstrual Bleeding S Irregular and Heavy Menstrual Bleeding S DUB should no longer be used as a symptoms, sign or diagnosis ( new ICD-10) will reflect this change S Replaced with more precise categories of etiology: AUB-E and AUB-O ( more to follow)

Simplified clarification system Frequency Frequent Norma Infrequent Absent < every 24 days Q 24 -38 days Every 38 days Regularity Regular Irregular Variation +/- 2 -20 days Variation > 20 days Duration Prolonged Normal Shortened Ø 8 days Ø 4. 5 to 8 days Ø < 4. 5 days Volume Heavy Normal Light Ø 80 mls per cycle Ø 5 -80 mls per cycle Ø < 5 mls per cycle

Volume? ? S Traditionally, bleeding measured by volume of menstrual blood lost (> 80 mls) S Actual volume of MBL per cycle is not the main reason women seek medical attention Heavy menstrual bleeding (HMB) is defined as excessive blood loss which interfere with a woman’s physical social, emotional and/or material quality of life. It can occur alone or in combination with other symptoms. UK NICE GUIDELINES 2007

Abnormal Uterine Bleeding (AUB) PALM Structural Causes Polyp AUB-P Adenomyosis AUB-A Leiomyoma's AUB-L (Fibroids) Malignancy & hyperplasia AUB-M COEIN: Nonstructural Causes Coagulopathy AUB-C Ovulatory and Endometrial AUB-O; AUB-E Iatrogenic and Not classified AUB-I; AUB-N

AUB-O Dysfunction S HEAVY and IRREGULAR S Absent ovulation-no corpus lutuem-ovary does not produce progesterone S (Fragile vascular endometrium with insufficient stromal support) S Continued estrogen stimulation without progesterone stimulated withdrawal bleed (As one are heals another begins bleeding) (Erratic unpredictable non-cyclic bleeding with inconsistent volume)

AUB-E: Endometrial Dysfunction S HEAVY AND IRREGULAR S Caused by local disturbances in endometrial function- deficiencies or excess of proteins that have an impact on coagulation S REDUCED LEVELS S Vasoconstrictors and Clotting Mechanisms S PG F@ alpha Endothelin-1 S Tissue Factor pathway

AUB treatment modalities PALM Treat structural problems you think are causing the bleeding -Wide variety depends on problem AUB-O and AUB-E LNG IUS Oral Progestin COC’s NSAIDS Trenexaminic Acid Endometrial Ablation AUB-C Refer to treatment of the coagulopathy AUB-I and AUB-N Address the iatrogenic or other factor , may consider AUB-O and E treatment options

Treatment of AUB-O and AUB-E S A small piece of the puzzle: S Other consideration: desire for future fertility, regional availability, contraindications or risk factors for adverse event costs, other treatments attempted

Treatment of AUB-E and AUBO S Effectiveness varies from patient to patient based on acuity, women with ovulatory dysfunction, and women with anovulatory dysfunction S Studies can be difficult to compare and interpret, population not always clear S Most studies excluded women with irregular menses S Most studies included only women with > 80 mls MBL

Acute AUB S This is an episode of bleeding characterized by significant blood loss in a large quantity to warrant immediate intervention to prevent further blood loss

Case Scenario S A 40 yo GO non pregnant woman presents to ER with heavy vaginal bleeding for the past reported 12 days. S On examination her vitals are stable and you observer a moderate amount of bleeding. Her Hgb is 9 g/dl. She is a non-smoker and has an otherwise negative history.

Which of the following would not be the best first line treatment for this patient? S A. Dilation and Curettage S B. Conjugated equine estrogen 25 mg IV q 6 hours S C. Oral contraceptives TID x 1 week S D. Medroxyprogesterone acetate 20 mg TID x 1 weeks

Estrogen S Use of IV Premarin in the treatment of DUB –Double blind RCT of 34 women S Compared proportion of patients in whom bleeding stopped in response to either 25 mg IV conjugated equine estrogen or IV placebo S In 5 hours, Bleeding stopped in 72% of patients who received IV estrogen therapy and in 38% who received placebo Devors et al 1982

COC Tapers/Cascades S Initially based on expert opinion until RCT by Munro et al October 2006 S Compared COC taper and oral progestin S 16 women in COC group S 95% avoided surgery in the next 28 days S Average 3 days to bleeding cessation COC with 35 microgram E 2/1 mg norethindrone TID x 1 week then qd x 3 weeks Munro et al 2006

Oral Progestin S Oral progestin arm of the Munro et al study S All 17 women in MPA group avoided unplanned surgical intervention S 65% stopped bleeding at 1 month follow-up with a mean time of 3 days S Medroxyprogesterone acetate 20 mg po tid x 1 week daily x 3 weeks Munro et al 2006

Tranexamic acid S Given its mechanism of action ( decreasing fibrinolysis) effective option for Acute AUB S Supported as a rx by experts both (PO and IV) S No studies for acute AUB S Shown to reduce intra-operative bleeding for orthopedic procedures 1. 3 grams po tid x 5 days or 10 mg/hg IV q 8 h for up to 5 days James et al 2011; Alshyrda et al 2011 Lethaby et al 2000; Lukes et al 2010

Case scenario S A 28 yo G 0 non-pregnant woman seeks treatment for heavy irregular bleeding which has been unpredictable for the last few weeks. This patient has a normal baseline transvaginal ultrasound and normal pelvic exam. She has no medical problems.

Which of the following are not options for this patient’s bleeding? S A. COC’s S B. Luteal phase progestin ( 10 -14) d/cycles S C. LARC-IUDS S D. Trenexamic Acid S E. NSAID’S

Combination Oral Contraceptives S For AUB-O: May work by inhibiting the growth and development of the endometrium exogenously cycling hormones S Physiologically makes sense though evidence is limited One RCT compared the efficacy of a triphasic combination COC’s in the treatment of women with irregular bleeding (some heavy, some not) 73. 2% of COC group reported bleeding was improved (vs. 39. 6% of placebo group) Davis et al 2000 Cochrane Review by Hickey et al , updated 2009

Levonorgestrel IUS-(MIRENA) S Suppression of endometrial proliferation, inactive histology, thin endometrium and decidualization of stroma S Most studies only AUB-E S Excluded women with irregular menses suggestive of AUBO S Probably a good chance for AUB-O as well given its mechanism of action Magnon et al, 2013

Levonorgestrel IUS (MIRENA) S LNG-IUS reduces MBL by 715 -95% S Most effective best tolerated non-surgical option for heavy and regular menstrual bleeding S Reduction in MBL same for LNG-IUS and extended cycle oral progestin S Patient satisfaction much less for oral progestin S More effective than COC’s, luteal phase oral progestin, DEPO MPA, NSAIDS Matteson et al 2013, Lethabey et al updated 2009 Lee et al 2012, Endrikat et al 2009

NSAIDS S Limited studies have shown NSAIDS effective in treating heavy and regular bleeding S No difference between NSAIDS in effectiveness (Naproxen, Mefenamic acid) S Less effective than tranexamic acid S Data limited comparing to luteal phase progestin, LNG IUS, COC’s Cochrane Review by Lethaby et al updated 2009

Endometrial Ablation S 1 st generation Resectoscopic S Rollerball S Transcervical endometrial resection S 2 nd generation; Non-Resectoscopic S Heated fluid (Hydrothermal Ablation) S Thermal Balloon ablation S Microwave S Cryotherapy S Radiofrequency bipolar

Global endometrial ablation S Most studies: only heavy and regular bleeding S Satisfaction: 50%-90% S Amenorrhea: 13%-64% S Failure rate: 8%-42% No difference between resectoscopic and global methods in bleeding reduction and QOL 2007 2009 Matteson et al; 2012 Dickerson et al 2007, ACOG PB Penninx et al 2011; Cochrane review by Lethaby et al

Success and Failure of Ablations S Predictors of amenorrhea S > 45 yo S Uterine length > 9 cm S Endometrial stripe < 4 mm S Predictors of failure S < 45 yo S Parity greater than or equal to 5 S History of dysmenorrhea El-Nashar et al 2009

Hysterectomy versus Ablation S Hysterectomy better S Bleeding reduction at 1 year S Satisfaction at 2 yrs post-op S Some evidence of improved health status S Ablation better S Surgery duration, hospital stay and recovery time S Most adverse events ( both major and minor) S Overall “costs” but not cost-effectiveness Dickerson et al 2007; Cochrane review by Lethaby et al 2009

Summary Points S Must consider the etiology behind the patient’s heavy bleeding Some treatments: S Effective for irregular bleeding, not regular bleeding S Only studied for regular bleeding-but does that mean the WON’T work for irregular bleeding S Man studies only include patient with confirmed MBL > 80 mls S Research in this area by small sample size variety of comparison groups, limited number of studies

Summary Points S Active AUB S IV estrogen, multiple pill regimens of progestin and COC; ’s appear to be effective, TCS also effective S AUB-E-Heavy and regular S LNG IUS and ablation-most effective TX S Shown effective-COC’s, TXA, 21 day Progestin, NSAID’s S AUB-O Heavy and irregular S Cyclic COC’s, luteal phase progestin S Limited date on other treatments (most studies excluded irregular bleeders
