“As a result of participating in this activity, the participant will be able to…”

…appreciate the impact of the W.H.I. on the treatment of Menopausal Symptoms

…demonstrate an understanding of subsequent studies reviewing the use of hormonal therapy

OBJECTIVES

…apply the principles of treatment based on current practice guidelines and position statements to current patients

…appreciate that the modality of therapy plays a marked role in the treatment of current menopausal patients

OBJECTIVES

This lecture is designed to evaluate the evolving use of hormones in postmenopausal patients since the publishing of the W.H.I. Study. It will discuss the evidence based medicine that has led this physician in his prescribing of hormonal therapy. It is hoped that this journey will impact the prescribing habits of other providers.

INTENT OF LECTURE

Use of estrogens can improve menopausal symptoms such as hot flashes (1940s)

Use of estrogens can cause thromboembolic phenomenon (1950s)

Use of estrogen can improve subjectively feminine sense of well being (1960s)

Use of unopposed estrogen can lead to endometrial hyperplasia or endometrial cancer (1970s)

LESSONS LEARNED PRIOR TO 2000

According to records of prescriptions, there were 129 million prescriptions for Hormonal Therapy (HT) including estrogen in the year 2000

In 2001, a Women’s Health Initiative (WHI) study was undertaken to evaluate the efficacy of Estrogen and Progestin as well as Estrogen alone in preventing heart disease in postmenopausal women

MENOPAUSE

After the 2002 WHI study was published approximately 65% of women on HT stopped therapy

In 2003, there were just over 76 million HT prescriptions dispensed

By 2008, this number had dropped to approximately 42 million prescriptions for HT in USA (29 million were for estrogen only RXs)

POST-WHI MENOPAUSE

“Trends in hormone therapy use before and after publication of the Women’s Health Initiative trial: 10 years of follow-up”

Published 2009 but showed the impact of the W.H.I. on European prescribing of estrogen in Barcelona, Spain

By 2007, there was a peak reduction of 89% in percentage of overall prevalence

Barbaglia, Gabriela MD, et al, Menopause Vol. 16, No. 9, 2009; 1061-1064

POST W.H.I. EFFECT

This was a retrospective cohort study of 300,000 inhabitants in Barcelona, Spain from 1998-2007

Women ages 50-69 years were evaluated The age groups evaluated were: 50-54; 55-

59; 60-64; and 65-69 In addition to prevalence, the percentage of

new users was also evaluated

POST W. H. I. EFFECT

Use of estrogen in postmenopausal patients should not be used in prevention of chronic illnesses especially cardiovascular disease

Use of estrogen if started should be considered early in Menopause (ages 50-59) for benefit of specific symptoms

Use of estrogen in postmenopausal patients is not for everyone

LESSONS LEARNED AFTER W. H. I.

“Postmenopausal Hormone Therapy and Risk of Cardiovascular Disease by Age and Years Since Menopause”

Rossouw et al reviewed the original data of the WHI and created a secondary analysis

The study reviewed both arms of the trials (E2 + P4 and E2 alone)

Rossouw, J. E. et al JAMA 2007; 297: 1465-1477

YEAR 2007

In the combined trials, there were 396 cases of CVD and 327 cases of stroke in the hormone treated group

In the combined trials, there were 379 cases of CVD and 239 cases of stroke in the placebo group

For women with less than 10 years since Menopause, the RR was 0.76 95% CI 0.50-1.16

Rossouw, J. E. et al JAMA 2007; 297: 1465-1477

YEAR 2007

Rossouw et al stated, “These analyses, although not definitive, suggest that the health consequences of hormone therapy may vary by distance from menopause, with no apparent increase in CHD risk for women close to menopause, and particularly high risks in women who are distant from menopause and have vasomotor symptoms.”

Rossouw, J. E. et al JAMA 2007; 297: 1465-1477

YEAR 2007

Use of Alternative Therapies (e.g. black cohosh, soy, dong quai) have not been shown to have “statistically significant” improvement of VMS in postmenopausal women

Use of estrogen should be started at the lowest possible dosage

Use of estrogen by topical or non-oral route should be considered to avoid the First Pass Effect of the liver

LESSONS LEARNED 2012

Reviewing the literature, I have made several decisions

Lack of estrogen causes hot flashes, night sweats, and VMS

These VMS can be substantial and in certain patients cause a change in quality of life

The treatment for VMS is estrogen

IN 2012, WHAT DO I DO?

In patients who have undergone hysterectomy, I discuss the use of estrogen for severe VMS and other quality of life issues

Given the difficulty with Alternative Therapies and the First Pass Effect of the Liver, I discuss extensively non-oral approach to treatment

Use of patch, cream, gel, lotion, and vaginal ring are legitimate treatments

IN 2012, WHAT DO I DO?

If the patient is agreeable, I start with the lowest dosage possible for four (4) weeks

After 4 weeks, I see the patient in follow-up to discuss the effectiveness of treatment

It will take upwards of two weeks to see improvement of the number or the intensity of the VMS for the patient

If there is excellent control of the VMS, the patient is seen in three months

IN 2012, WHAT DO I DO?

In patients who have severe atrophic vaginitis and have reservations about use of systemic estrogen, then I offer topical vaginal estrogen either by cream or tablet

In some patients who are already on systemic estrogen for VMS but continue to have problems with severe atrophic vaginitis, I will supplement with topical vaginal estrogen

IN 2012, WHAT DO I DO?

Once a patient is stabilized on the estrogen for VMS/Quality of Life issues, she is seen at 6 months and then 12 months

Every year she returns for her annual examination including pap smear and mammogram, a discussion regarding the use of estrogen is done

New information from the literature is given to the patient and discussion regarding continuation of therapy commences

IN 2012, WHAT DO I DO?

In patients who have not had a hysterectomy (have an intact uterus), the discussion regarding therapy is more extensive

The patient is specifically explained about the WHI and the risk of breast cancer

The severity of the VMS is weighed against the concerns generated for breast cancer

If patient wishes to proceed, she is started on estrogen alone first

IN 2012, WHAT DO I DO?

The same principles for starting estrogen (lowest dosage, non-oral) are followed

The patient is continued on increasing dosages of estrogen until her VMS are stabilized

Once the VMS are treated, then progestin/natural progesterone is added to prevent endometrial stimulation

IN 2012, WHAT DO I DO?

In neither scenario do I obtain Serum Estradiol Levels or for that matter LH/FSH unless patient is uncertain she is postmenopausal

I do not do pretreatment endometrial biopsy or transvaginal ultrasound

I do mandate a pretreatment mammogram for determining occult breast cancer/ breast calcifications

IN 2012, WHAT DO I DO?

After a patient has been on either estrogen alone or estrogen with progesterone for greater than one year, I talk seriously about decreasing the amount of medication or even stopping the medication

If VMS recur, then the patient will resume at her previous treatment dosages

Most patients use the hormonal therapy for an average of 3-4 years

IN 2012, WHAT DO I DO?
