after speaker on the subject of natural hormones in clinical
practice. Stephenson is currently an Associate Professor of
Family Medicine at The University of Texas Health Science Center
in Tyler, Texas.
General
Overview of the Results
Cardiovascular
disease is the leading cause of death and disability in American
women. Our concern is that there are hormonal factors involved,
and our research suggests that if we address those hormonal
factors primarily, then there’s a downstream effect on the
cardiovascular biomarkers showing a benefit. The WISE [Women and
Ischemic Events] studies by NIH Heart, Lung and Blood Institute
and others over the last decade suggest that there is a
gender-specific pathophysiology as it relates to cardiovascular
disease. This clustering effect in peri-menopausal and
post-menopausal women of an elevated fasting glucose, elevated
triglycerides, elevated CRP and elevated pulse pressure, all
contribute strongly to cardiovascular disease risk, along with
psychosocial factors of anxiety and depression.
We saw benefit in
all of these domains both at eight weeks and at 12 months. We
saw improvement in their depression and anxiety scores, we saw a
decrease in fasting glucose and fasting triglycerides, we saw a
decrease in CRP, we saw a decrease in systolic pressure and
pulse pressure.
Excerpts from
an Interview with Dr. Stephenson & Women in Balance:
WIB:
Taking on a study like this involves an enormous commitment of
time, energy and fund raising. What inspired you to take on this
task?
KS: I started using compounded [natural] hormones in
clinical practice about a decade ago and observed an oftentimes
dramatic benefit and very few side effects or problems. I wasn’t
entirely comfortable prescribing them because of the paucity of
clinical studies, especially long term, with specifically
compounded hormones. I wanted to make up for that deficit in the
U.S. research literature in a prospective, 36-month, long-term
study to look at clinical outcomes with the compounded hormones
as well as potential for harm.
I was really
spurred on after the Women’s Health Initiative [WHI] when all
hormones were condemned equally. My thinking in looking at the
clinical literature, epidemiological studies and experimental
studies is that hormones are not all equal as it relates to
their pharmacology and physiology, and that there are distinct
differences with the compounded hormones. This needed to be
explored further instead of just saying,
“Hormones are
dangerous, hormones are bad, we can’t use them anymore, we’ve
got to look at non-hormone therapies for hormone-related
symptoms.”
We started
recruiting for the CHOIICE study in 2005. The second arm of the
WHI, the Premarin-only study, was halted in 2004. I think the
timing was good in that there were women who had been off
hormones for awhile because of the fear-based knee jerk response
by a lot of physicians and patients, and yet women were
suffering and looking for relief.
WIB: What
were the criteria for women entering the study? Did you choose
women suffering from specific menopausal symptoms?
KS: We did not seek out women that were having menopausal
symptoms. We looked at women who were perimenopausal and
postmenopausal, between the ages of 30 and 70, and who were free
of any severe chronic diseases. They could not be on a statin or
other cholesterol-lowering drugs, they could not be on a COX-2
inhibitor, they could not be on any hormones, and had to be
cancer-free for five years. Those are the inclusion/exclusion
criteria.
We documented
their symptoms at baseline and on follow-up. There were a few
women that did not have hormone-related symptoms because that
was not an inclusion criteria, but part of our hypothesis is
that if women have depleted levels of sex steroid hormones, and
those levels are vital to multiple systems in the body, then it
would benefit them to have those levels restored. Maybe they
don’t feel it as it relates to having a hot flash or a night
sweat, but does it reflect on say, cardiovascular markers? Does
it behoove them perhaps in a preventive way, in a proactive way,
to have their hormones evaluated and then restored if they’re
deficient?
WIB: How
many women total are in the study?
KS: Seventy-five in the interventional group, and then 75
in the control group. The control group are women in the clinics
at our facility that are receiving conventional care. They’re
ethnic and age-matched controls. Those women are receiving,
let’s say, statins, antidepressants, anxiolytics [drugs for
anxiety] and conventional hormone therapy from their providers.
This is a three-year study. The data that we reported at
American Heart Scientific Sessions last month [November 2008]
was the 12-month data.
WIB: What
were the markers that you chose to measure?
KS: Our high interests were in thrombotic [stroke/blood
clot] factors because there is a large body of clinical and
experimental evidence demonstrating that conventional hormone
therapy does increase thrombotic risk when given orally. Then
there have been statements by entities such as the North
American Menopause Society that progesterone should be inferred
to have the same thrombotic risk as medroxyprogesterone acetate
[e.g. Provera], yet there’s not evidence of that—but again there
was no lack of evidence either. We had a high interest in what
was happening with hemostatic factors. We looked at factor VII,
factor V, factor VIII, antithrombin III, fibrinogen activator
inhibitor and fibrinogen. These factors may be reduced or
elevated in patient populations and then lead to risk of stroke
or heart attack, pulmonary embolism or venous thrombosis.
Both the PremPro
arm and the Premarin arm of the WHI were stopped early because
of increased thrombotic risk, so we measured all of these
factors and did not see any significant changes that would be
pro-thrombotic, and we saw, with several of the factors, a
statistically significant beneficial change. That change was
most pronounced in the postmenopausal women.
We also looked at
other biomarkers for cardiovascular disease: the inflammatory
factors such as C-reactive protein [CRP] and we looked at
clinical measures of systolic blood pressure, diastolic blood
pressure, pulse pressure, fasting blood glucose, fasting
insulin, fasting triglycerides. Then we looked at a mood scale
for depression, anxiety, as well as the Greene Climacteric
Scale, a numerical index that scores 21 menopausal symptoms. We
looked at a depression and anxiety scales scale because of data
from the POWER study and the ATTICA study—both demonstrate that
when women have a mood state of anxiety or depression, they have
an increase in both pro-thrombotic and proinflammatory factors
irrespective of whether they’re on psychotropic drugs, they
smoke, or their BMI [body mass index, or weight]. A woman’s
emotional state will affect these biomarkers, so it was
important for us to quantify that.
WIB: How
did you decide which hormones to put the women on?
KS: For each patient that met the strict
inclusion/exclusion criteria and entered the study, we performed
baseline hormone profiles. We looked at estrogen, progesterone,
testosterone, DHEAS, and we also looked at their cortisol
circadian rhythms. We used saliva testing, which our research
team feels is the best measure of bio available hormones. Then,
if the patients had sub-optimal levels of progesterone they were
given progesterone during the first eight weeks. If they had
sub-optimal levels of both estrogen and progesterone they were
given both of those for the first eight weeks. The first eight
weeks did not include any androgens [male hormones]. Then we
retested the patients and at that point if they had low
androgens we added in androgen therapy. All of our hormones were
given transdermally [through the skin, via cream]. There is a
myth out there that androgens are harmful to women, but some of
that may come from the fact that very high doses of oral
synthetic androgens have been shown to have adverse effects. And
of course that’s distinctly different than the transdermal low
dose compounded androgens that were given to our patients.
WIB: How
did you decide the amounts of hormones to give them?
KS: We used the formulary for health care professionals
that’s published in my book, Awakening Athena. I used that
formulary in clinical practice for nearly a decade. Then the
prescriptions were titrated to physiologic reference ranges
because women have different responses to hormone therapy. Some
women may be rapid metabolizers, some slow metabolizers, so
that’s why it was important that we monitor and retest them. One
patient may need 20 mg of progesterone to get her to target, and
another may need 40 mg or 60 mg. We’ve looked at the patients
collectively as it relates to risk and benefit and the type of
hormone therapy. But as far as the dosing, women have to be
treated individually, and they need individual dosing. It is not
good enough to just categorize them based on their uterine
status or symptoms. Each patient received her specific hormone
dose based on her saliva test profile results. It sounds complex
but it’s really not, and it sure saves a lot of time in the long
run.
WIB: And
the women sure feel better!
KS: We proved that I think. Our hypothesis was that we
would not see the elevated thrombotic factors, but we were very
surprised to see this global benefit in all domains. We felt
that we would see some, but it was quite surprising to us to see
the statistically significant beneficial changes across the
board.
WIB: Very
exciting. Would you give us a general overview of the results?
KS: Cardiovascular disease is the leading cause of death
and disability in American women. Our concern is that there are
hormonal factors involved, and our research suggests that if we
address those hormonal factors primarily, then there’s a
downstream effect on the cardiovascular biomarkers showing a
benefit. The WISE [Women and Ischemic Events] studies by the NIH
Heart, Lung and Blood Institute and others over the last decade
suggest that there is a gender-specific pathophysiology as it
relates to cardiovascular disease. This clustering effect in
peri-menopausal and post-menopausal women of an elevated fasting
glucose, elevated triglycerides, elevated CRP and elevated pulse
pressure, all contribute strongly to cardiovascular disease
risk, along with psychosocial factors of anxiety and depression.
We saw benefit in all of these domains both at eight weeks and
at 12 months. We saw improvement in their depression and anxiety
scores, we saw a decrease in fasting glucose and fasting
triglycerides, we saw a decrease in CRP, we saw a decrease in
systolic pressure and pulse pressure.
WIB: Do
you plan to continue to follow these women when the study is
over?
KS: Funding is the issue. It’s been quite a struggle to
do this study on a shoestring. We’re competing with Big Pharma
studies that are very generously funded, where there’s want of
nothing. We’ll probably survey the women, but I don’t know that
we’ll be able to afford much more than that.
WIB: Do
you have any insights that you can share from your own clinical
practice?
KS: I think the most compelling thing that I can share as
it relates to women’s health and assessing women in this age
group, is that when they are pre-hypertensive and pre-diabetic,
by clinical criteria, it is vital to know their hormone profile.
Starting treatment with pharmacotherapy [drugs] to lower blood
pressure, triglycerides or blood sugar may create problems with
drug interactions or side effects, or not have a global
protective effects. By knowing a woman’s hormone profile and her
hormone status, and by testing that first, you may see a
significant improvement in her blood pressure, her lipids and
her glucose.
WIB: So
doctors can use a treatment that’s safe and effective, is
replacing what’s depleted, and addresses the whole body, rather
than treat specific symptoms with a pharmaceutical drug
approach. You’re treating an underlying cause rather than a
symptom.
KS: Yes. That is what I try to emphasize with the medical
students and the residents. Metabolic syndrome is so prevalent
and is increasing in this patient population. Hormone factors
are the priority.
WIB: How
do you treat women whose cortisol is out of balance and
indicating tired adrenals?
KS: First I want to know what’s happening with her
progesterone. If the progesterone is low, then I prescribe
transdermal progesterone along with nutritional and lifestyle
counseling. That’s my primary approach.
WIB: Does
the nutritional/lifestyle counseling include getting more sleep,
eating less sugar, stress management and exercise?
KS: Yes. We counsel women with low adrenal function to
pay attention to the glycemic indices of food, to take the time
to restore and recharge. Even if she’s working two jobs. Some of
my patients are working three jobs. They need to find somewhere,
even if it’s just a twenty-minute break, to help de-stress.
Maybe she can take 30 minutes on an hour lunch break to do some
yoga work or aerobic type exercise. That’s what I counsel the
patients initially. And then if the adrenal depletion is more
profound or severe, I will oftentimes have them take
supplements.
WIB: What
types of supplements do you recommend?
KS: I primarily use James Wilson’s protocols and
supplements. [www.adrenalfatigue.org].
WIB:
Thanks so much for your time and attention, Dr. Stephenson. This
is a beautifully thought-out and executed study, and it will
change how doctors approach women’s health. We look forward to
talking with you next year about the results of the second year
of the study.
