Abnormal Uterine Bleeding

Randy A. Fink, MD, FACOGObstetrics & Gynecology

A simplified approach for primary care

Disclosures

I have no relevant disclosures pertaining to this program.

Learning Objectives

• Demystify and understand a simple, straightforward template to evaluate premenopausal abnormal uterine bleeding in the primary care setting.

• Review up to date treatment options for heavy menstrual bleeding.

Appreciate the evaluation and management of postmenopausal bleeding.

What’s In a Name?

• AUB• DUB (Dysfunctional Uterine Bleeding)• Irregular Menstruation• Metrorrhagia• Menorrhagia• Menometrorrhagia• “Hemorrhaging”• “It’s like a murder scene.”

What’s In a Code?

International Classification of Diseases, Tenth Revision (ICD-10): http://www.cdc.gov/nchs/icd/icd10.htm

Oh yeah, it’s a problem…

• One-third of visits to GYN practice1

• 11-13% of reproductive age women at any given time2

• Increasing prevalence with age to 24% by 36-40 years old.

Risk Factors for Endometrial Cancer

• Increasing Age (50-70yo)• Early menarche

• Late menopause (after 55yo)

• Chronic anovulation

• Diabetes• Obesity

• tamoxifen• Unopposed estrogen

• Nulliparity• Lynch Syndrome• Estrogen secreting

NORMAL MENSES

• Frequency of menses within a 24 to 38 day window• Regularity (cycle-to-cycle variation) within ± 2 to 20

days• Duration of flow from 4 to 8 days• Volume of blood loss from 5 to 80 ml

Beta-HCG

• Urine Pregnancy Test - within 2 weeks of conception– (20-50 mIU/mL)

• Serum Pregnancy Test (QUANTITATIVE ) – by 1 week after conception– (1-2 mIU/mL)

• False positive (rare)• False negative (more common)

Early Pregnancy Bleeding

• RULE-OUT ECTOPIC (2% of all pregnancies)– “Discriminatory Zone”: If Beta-HCG ≥ 2000, Intrauterine

Pregnancy is generally seen by transvaginal ultrasound1

– Normal: Beta-HCG rises by 35% in 48 hours OR doubles in 72 hours during 1st 40 days of pregnancy2

• MISCARRIAGE (15-20% of all pregnancies)– If Fetal Heart Rate is observed, 90-96% of these pregnancies

Signs of Hyperandrogenism

• Biochemical– Elevated Testosterone (<150

ng/mL)

– Elevated DHEA-S– 8am 17-OHP

– TSH, FSH, Prolactin

Signs of Hyperandrogenism

• Hirsutism– Hair growth in androgen

dependent areas:• Upper lip, chin• Midsternum• Upper and lower abdomen• Upper and lower back• Buttocks

• Differs from – “Unwanted Hair”– Hypertrichosis Madnani N et al. Indian J Dermatol Venereol Leprol 2013;79:310-21

Ferriman-Gallway Hirsutism Scoring

• Score 1-7: Focal (common normal variant)

• Score ≥8: Generalized

• Norms lower in Asians, higher in Mediterraneans

Signs of Hyperandrogenism

• Hirsutism with Acanthosis Nigricans– Insulin resistance

Madnani N et al. Indian J Dermatol Venereol Leprol 2013;79:310-21

Signs of Hyperandrogenism

• Acne Vulgaris– Minimally responsive to

traditional treatment

– Lower half of face and jawline

– Back, chest– Rapid recurrence on cessation

of treatment

– Persist beyond typical 5-7 days

Archer JS, Chang RJ. Hirsutism and acne in polycystic ovary syndrome. Best Pract Res Clin Obstet Gynaecol 2004;18:737-54.

Signs of Hyperandrogenism

• Androgenic Alopecia– May be difficult to distinguish

from other patterns of hair loss in women

ANOVULATORY PATTERN

• Common Clinical Presentation– 33yo nulligravid, BMI 30, states not sexually active.

• c/o vaginal bleeding daily for the past 24 days• LNMP 3 months prior, no bleeding since until this episode

• Hormone Dysfunction: Estrogen Dominance– Progesterone Challenge

• Medroxyprogesterone acetate 10mg PO BID x 5 days or 1 PO QD x 10 days

• Norethindrone acetate 10mg PO QD x 5 days

Deeper Issues

• Prolactinoma• Thyroid abnormalities• Premature Ovarian Insufficiency• Coagulopathy/Bleeding Diathesis

TSH, FSH, PROLACTIN

HORMONAL STRUCTURAL• Cervical• Fibroids• Polyps• Adenomyosis

Is it Uterine Bleeding? Remember Cervix!

• Cervical Dysplasia– Is Pap up to date? If not, DO IT!

• Cervicitis– Friable cervix– Purulent discharge

– Pelvic tenderness

Fibroids

• Most common pelvic tumor in women1

• Prevalence as high as 77%

• Clinically significant (4cm, 9 weeks size, Submucosal) by u/s2

– 50% of Black Women

– 35% White Women1Baird DD, Dunson DB, Hill MC, Cousins D, Schectman JM. Am J Obstet Gynecol. 2003;188(1):100.2Marshall LM, et al. Obstet Gynecol. 1997;90(6):967.

Fibroids

• Heavy or prolonged menstrual bleeding• Bulk-related symptoms, such as pelvic pressure and

pain

• Reproductive dysfunction (i.e., infertility or obstetric complications)

6/26/2018

13

Endometrial Polyps

• Common source of perimenopausal and postmenopausal bleeding

• Receptor issue• Saline sonography• Can be stimulated by estrogen therapy, tamoxifen,

endogenous estrogen• 95% are benign

Adenomyosis

Adenomyosis

• Common cause of pelvic pain, dysmenorrhea, abnormal uterine bleeding

• Globular uterus• Asymetric endometrial growth• Heterogeneous echotexture• Diffuse or confined (Adenomyoma)

Treatment Options - HMB

• NSAID• Hormonal Contraceptives

• Tranexamic Acid 650mg, 2 tabs PO TID starting at onset of menses, not to exceed 5 days use

• LNG IUD

• Endometrial Ablation

PRE-MENOPAUSAL POST-MENOPAUSAL

Post-Menopausal Bleeding

• IS IT UTERINE?– Cervical– Vaginal Atrophy– Urethral– Rectal

• IS IT MEDICAL?– HRT– Anti-coagulants
