Medical Conditions More Common After Menopause
> Osteoporosis > Atherosclerotic disease

Stenchever MA, et al. Comprehensive Gynecology, 4th ed. 2001. Wenger NK. Brit Med J. 1997.

Fear & Confusion After the WHI & HERS

Overview of HERS
Heart and Estrogen/progestin Replacement Study (HERS) > Secondary prevention in women with CHD > Found CEE with MPA does not reduce MIs > More CHD events in hormone group during Year 1

Coope J. Management of the Menopause and Post-Menopausal Years. 1976. Baumgardner SB, et al. Obstet Gynecol. 1978.; Stampfer MJ, et al. N Engl J Med. 1985.; Wilson PWF, et al. N Engl J Med. 1985.; Hulley S, et al. JAMA. 1998.

Overview of WHI
Women’s Health Initiative (WHI ) > Primary prevention in healthy women > Age 50-79 (mean 63 y) > Post-menopause (mean 12 y) > Treated with CEE with (or without) MPA > Primary outcome rate of fatal or non-fatal MI > E-P arm terminated July 2002 > E-only arm terminated March 2004
Rossouw JE, et al. JAMA. 2002. Anderson GL. Press conference remarks. 2004.

Understanding WHI Results

WHI Results: CHD
E-P arm
HT neither protected nor worsened

23% decrease
Approached statistically significant

Time trend existed
Chlebowski, RT. JAMA. 2003. WHI Steering Committee. JAMA. 2004.

WHI Results: VTE

Rapp SR, et al. JAMA. 2003. Shumaker SA, et al. JAMA. 2003. NIH. 2004.

Non-significant trend toward increased risk

Understanding WHI Results
What WHI results do not tell us > Benefits and risks of beginning HT at menopause > Benefits and risks for treatment of menopauserelated symptoms > Use of other doses, formulations, regimens, durations, and routes of administration of HT > Information on events after cessation

Putting WHI Results into Context
> Well-designed study of mostly asymptomatic women distant from menopause > Results have been generalized to other groups and to other HT formulations > Not yet known if findings apply

Lobo RA. Arch Intern Med. 2004.

Translating Results into Clinical Practice
Oral hormone therapy & post-menopausal women

Not for cardio protection

Not for treating CVD

ACOG Guidelines
Not for prevention of cardiac disease or osteoporosis

May be appropriate to treat menopause-related symptoms
Shortest possible duration in smallest effective dose

ACOG. 2004.

NAMS Guidelines
Extended use may be acceptable for some women Do not use for prevention of stroke, CHD, or osteoporosis Use local therapy for vaginal symptoms Use for shortest duration possible

North American Menopause Society. Menopause. 2003.

NPWH Guidelines
Women whose QoL is affected are best candidates Use lowest dose and shortest duration Use local therapy for urogenital symptoms

Women’s choice about duration should be respected

Nurse Practitioners in Women’s Health. 2004.

FDA Guidelines
Effective for treating vasomotor symptoms and vaginal dryness, preventing osteoporosis Use topical therapy for vaginal dryness alone Use as last resort for osteoporosis prevention alone

Use lowest dose and shortest duration possible

Food and Drug Administration. 2004.

Counseling Patients About HT
Each woman must weigh risks and benefits in light of her circumstances
Women must put risks into perspective to make fully informed decision Each woman must clarify her purpose and goal for using HT

Contraindications to Systemic ET
> > > > > > Pregnancy VTE Breast cancer Estrogen-sensitive cancers Liver disease Hypertriglyceridemia

Weighing Risks and Benefits
Provide accurate information Ask: “What are the risks and benefits for you?” Ask: “Do you have concerns about HT?” Discuss lifestyle changes

Understanding Risk
Relative Risk Helps investigators identify causes Absolute Risk
Helps assess impact on an individual

> WHI: 26% increase in breast cancer in E-P arm > This does not mean 26% chance of getting breast cancer
International Food Information Council. 2004. Nurse Practitioners in Women’s Health. 2004. Rossouw JE, et al. JAMA. 2002.

Clarifying Goals or Purpose
Risk/benefit ratio varies based on goals “What is most important among your menopauserelated health concerns?” “Why do you want to start/continue HT?”

Individualizing Hormone Therapy
Requires: > Familiarity > Understanding how to help a woman find the best product and regimen

Types of HT: Estrogens

17 betaestradiol

Conjugated equine estrogens (CEE)

Estrone derivatives

Types of HT: Progestogens

Requirements of Individualized Care
Gathering specific health-related information Providing accurate, patient-specific HT information Supporting informed decision making Addressing ongoing health needs

Case 1: Mary S.
> > > > > Final menstrual period 18 months ago at age 49 Healthy with no CHD risk factors Hot flashes daily Herbal remedies not helping “Terrified of those hormone drugs”

Case 1: Recommended Management
> Symptomatic with no contraindication > Candidate for systemic HT, not local HT > To decide on route, consider her preference, medical history, other factors > Progestogen needed if oral, transdermal, or systemic vaginal therapy is chosen

Case 2: Zelda K.
> > > > 60 years old 8 years postmenopausal Has never taken HT Severe dyspareunia, urinary urgency, and frequency X 1 year > Does not want oral HT, because friend had DVT on it

Case 2: Recommended Management
> > > > Severe genitourinary symptoms No vasomotor symptoms Candidate for vaginal estrogen Could use cream, tablet, or locally acting ring (Estring)

Case 3: Ann P.
> 56 years old > Was taking oral HT for vasomotor symptoms > Internist told her to stop HT > Off HT several months > Vasomotor symptoms gone but sexual desire low > Wants to restart HT > No contraindications to systemic HT

Case 3: Recommended Management
> Provider should ask about sexual function, relationship, and pharmacological issues to clarify cause > Low sexual desire may be related to low hormone levels > May be candidate for restarting HT, possibly with androgen

Case 4: Terri O.
> > > > 48 years old Perimenopausal Menses generally regular Experiencing hot flashes, mood swings, and fatigue > Requests HT > Had DVT on oral contraceptive at age 35 > No other medical problems

Case 4: Recommended Management
> HT should not be used during perimenopause > OCs contraindicated > Could use estrogen augmentation with patch > Does not need progestogen – menses still regular > Needs progestogen challenge if no menses X 3 months > Before any form of HT is started, possibility of pregnancy should be investigated, as appropriate

Case 5: Katherine W.
> 54 years old > Post hysterectomy without oophorectomy > Recent severe vasomotor symptoms and forgetfulness > Afraid of HT > Family physician told her recent studies showed “HT causes breast cancer” > Healthy, no contraindications to HT

Case 5: Recommended Management
> Candidate for oral or non-oral systemic HT > Does not need progestogen > Provider should educate about actual risks associated with HT > HT could be used for a short time, then gradually reduced to avoid estrogen withdrawal symptoms

Case 6: Debra R.
> 58 years old > Has taken oral HT for 4 years > Vasomotor symptoms and vaginal dryness have returned over past 3 months

Case 6: Recommended Management
> If adherence not an issue, relapse likely because of increased SHBG caused by oral estrogen > Options include adding androgen or changing to non-oral estrogen

Recommendations for Further Study
> HT using other routes of administration, hormone components, and regimens > Comparison of “bio-identical” products > Use of androgens alone or with HT > Factors that affect patient adherence > How patients make decisions about HT > Optimal regimens for discontinuing HT

Summary
> Patients and providers have been confused about HT as a result of the WHI and HERS data > Understanding study results and limitations helps providers counsel women to make informed decisions about HT > Individualization of therapy is essential for women who decide to use HT
