RESEARCH SECTION: Cortisol, Cortisol, Cortisol! - The Cortisol Edition
Background: Dozen’s of studies over the past twenty years have made the cortisol easily
the most intensively studied substance in chronic fatigue syndrome (ME/CFS). Why study cortisol?
Cortisol is the endpoint of the stress response centered in the HPA axis
(hypothalamus-pituitary-adrenal) and low cortisol can
many of the symptoms found in chronic fatigue syndrome (ME/CFS) such as
fatigue, malaise, sleepiness
and muscle and joint pain. To top it off, cortisol has a major effect on how
well our immune system functions.
Dig Deeper: Check out "The Hypocortisolism
in Chronic Fatigue Syndrome (ME/CFS) - Artifact or Central Factor?"
The results of the Pharmacogenomic’s studies prompted the Centers for
Disease Control (CDC) to focus
strongly on cortisol and follow up gene studies suggest ME/CFS patients may
have an inherent
susceptibility to the negative effects of low cortisol.
Success Snapshots
Sick for 10 years Lynn was ill enough at one point
that her internist, fearing she had congestive heart failure, felt she
should see a cardiologist. At the end of her rope with regards treatment she
reluctantly tried the exercises in Donna Eden's book 'Energy Medicince'.
They helped but she was still severely impaired. Then she tried Ashok
Gupta's Amygdala Retraining program and within 6 weeks reported she went
from @40% to 85% functioning; her riding car is history, her cane is gone
and she's working out on a stationary bicycle. Essentially she said "I no
longer have CFS. Now I'm just a fat middle-aged lady who's way out of shape.
But not for long." To read her story click here.
The triad of low cortisol readings in ME/CFS, fibromyalgia and
post-traumatic stress syndrome have
lead some to posit that low cortisol play an important role in
multi-systemic disorders associated
with fatigue and pain. Other researchers see low cortisol levels in
rheumatoid arthritis and other
autoimmune disorders that chiefly strike women and wonder about a cortisol/immune
connection.
Still studies that show cortisol levels are only mildly low in chronic
fatigue syndrome (ME/CFS) (and
sometimes not even that) may lead one to legitimately question how important
a role this substance
could play in this disease. The studies reviewed below suggest that even
after all this study that
cortisol still remains a dynamic field of inquiry. Dr. Holtorf not only
believes cortisol levels can
play a major role in the disease but that those ‘mildly low’ cortisol levels
may not be mildly low
after all. The CDC study at the end of the newsletter suggests that low
cortisol levels probably play
a more important role in women than men. Another recent study suggests low
cortisol levels may impact
ME/CFS patients ability to respond to other treatments – that study,
however, will appear in another
newsletter.
Paper of the Month: Cortisol to the Rescue?
A Case for the Use of Low-Dose
Cortisol in Chronic Fatigue Syndrome (ME/CFS
Holtorf, K. 2008. Diagnosis and treatment of hypothalamic-pituitary-adrenal
axis dysfunction in
patients with chronic fatigue syndrome and fibromyalgia. Journal of Chronic
Fatigue Syndrome 14;3
A former of patient of Dr. Holtorf who returned to health created the
Fibro-Fatigue Centers, a string
of clinics across the U.S. that treat chronic fatigue syndrome (ME/CFS), FM
and other diseases using
Dr. Holtorf’s protocol. Dr. Holtorf and Dr. Teitelbaum – who is now the
director of the FF Centers –
are both known for advocating the use of low dose hormones in combination
with a comprehensive
treatment plan to correct often undetected hormonal abnormalities – a
controversial approach.
Something in their approach seems to be working. In the latest edition of
Fatigued to Fantastic Dr.
Teitelbaum cites unusually high recovery rates: 40-50% of patients back to
85-100% functioning,
another 20-30% with significant improvement. In this paper Dr. Holtorf cites
an ongoing study
indicating that 94% of his patients had significant improvement by their 4th
visit with average energy
levels more than doubling (3.0-6.7 to 7.6 at 9th visit). They weren’t well
(6.7 out of 10 on the
energy scale) but they clearly improved a great deal.
Dr. Holtorf uses a multi-dimensional program in which hormones play just one
(if a major) role. Could
the use of low dose hormones - something of a minority approach in chronic
fatigue syndrome (ME/CFS)
treatment – be making the difference? In this paper Dr. Holtorf lays out the
case for low dose hormone
treatment in this disease and addresses concerns that low dose hormone
treatment could, over time,
lead to hormonal suppression.
Evidence -
Dr. Holtorf believes that studies thus far do, in spite of contrary
interpretation, support a finding
of significant dysfunction of the hypothalamus-pituitary-axis (HPA) in
chronic fatigue syndrome
ME/CFS. The HPA axis is one of two major stress response systems in the
body. The main stress hormone
produced by the HPA axis is cortisol. Dr. Holtorf argues that studies of
basal cortisol levels (while
the system is at rest) miss the central problem; an inability of this major
stress response system
to respond properly to stress.
Another (rather disillusioning) problem concerns the tests themselves; Dr.
Holtorf provides some
evidence indicating that the immunoassays typically used by labs to test for
cortisol levels (e.g.
Bayer Advia Centaur, Abbot TDx, DPC Immulite 2000, Amerlex, Baxter
Diagnostics) are inaccurate and
often overestimate cortisol levels compared to more accurate testing
protocols (gas
chromatography/mass spectrometry (GC/MS) and high performance liquid
chromatography (HPLC)).
Success Snapshot
After seven years of ill health but no diagnosis or improvement X visited a
chiropractor to help her
with her painful neck, shoulders and headaches. He advised her to visit an
endocrinologist
specializing in ME/CFS etc. who informed her that she did indeed have
ME/CFS; her thyroid was out of
synch, she had low vitamin D and high homocysteine levels and adrenal
exhaustion. He put her on diatroxin + eltroxin, vitamin D, high levels of B-12, B6, DHEA, N-acetyl
choline (liver), Co Enzyme
Q10 and testosterone (!). Within a week she reported she was feeling much
better – her breathlessness
was reduced and the pain and weakness in her arms and legs had almost all
disappeared. She called her
improvement ‘miraculous’ but then caught a very bad cold and had to revert
to complete bed rest but at
last report was doing much better.
A more important problem lies in the types of tests used. Dr. Holtorf
believes the problem in
producing cortisol in CFS does not lie in the adrenal gland (which directly
produces cortisol) but
higher up in the pituitary or hypothalamus (where the initiating signals
come from). While baseline
cortisol and ACTH stimulation tests have had inconsistent results, tests
that examine central HPA axis
activity (using CRH, IL-6, d-fenfluramine, IST, metyraponine) have
consistently (15/16) demonstrated
abnormalities.
Hormonal Suppression – The fear when taking cortisol (cortisone) is that
doing so will permanently
turn off the adrenal gland. The consequences of hormonal suppression are
significant and include
adrenal damage, bone loss and immune suppression. Dr. Holtorf believes,
however, that hormonal
suppression is a function of the higher doses in pharmaceutical drugs and
does not occur with the
lower levels in the bio-identical hormones (<15 mg) he uses. Far from
depressing HPA axis and immune
functioning, he reports that low dose hormone supplementation actually
improves HPA axis and immune
functioning, including specifically NK cell activity – a key immune player
in ME/CFS.
Treatment -
Dr. Holftorf noted that a low dose cortisol treatment trial (5-10 mg/day)
for one month resulted in
significant reductions in fatigue and disability in ME/CFS. Dr. Teitelbaum’s
comprehensive treatment trial administered cortisol if one of the four following conditions were
met: baseline cortisol levels
<12; ACTH stimulation tests resulted in <7 cortisol increase in 30 minutes
or <11 increase at 60
minutes; 60 minute cortisol levels <28; or if symptoms suggested cortisol
suppression was present.
This comprehensive treatment plan resulted in significant improvements with
no evidence of adrenal
gland suppression.
Dr. Holtorf reported that a very large ongoing study (4000 patients) at the
Fibro Fatigue Centers
indicates that physicians using a simpler formula had significant positive
results; 85% of patients
Notice: Prescribing low doses of bio-identical hormones for patients with low-normal cortisol levels is
controversial. While several prominent physicians regularly prescribe
bio-identical hormones others
are emphatically against prescribing hormones unless clear evidence of
hormone insufficiency is
present. One prominent physician told me that taking hormones would make me
feel better at first but that my adrenal gland would turn off leaving me dependent on hormone
supplementation.
were ‘improved’ by the 4th visit; 56% reported ‘significant improvement’ and
40% ‘substantial
improvement’ by the 4th visit and 62% reported significant improvement and
46% substantial improvement
by the 7th. Side effects were rare and minimal when they occurred.
Dr. Holtorf proposes that low dose cortisol (<15 mg/day) offers the
possibility of substantial
benefits for CFS with much less risk than many of the standard therapies
(NSAIDS, anti-depressants,
muscle relaxants, low-dose narcotics) now used to treat the disease.
Takeaway Points
- Dr. Holtorf presents evidence suggesting that cortisol
levels in many chronic fatigue syndrome (ME/CFS) patients are lower that
most tests indicate.
- Dr. Holtorf reports that preliminary results from an large ongoing study at the Fibro-Fatigue
Centers suggests that many patients at the Centers do significantly
improve over time. This study has not been published.
- Dr. Holtorf asserts that the use of low dose bio-identical hormones is
more effective and less risky than many treatments commonly used in the
disease.
Stress Response – What Stress Response?
Jerjes, W., Taylor, N., Wood, P. and A. Cleare. 2006. Enhanced feedback
sensitivity to prednisolone in
chronic fatigue syndrome. Psychoneuroendocrinology 32: 192-198.
Most studies have found that the HPA axis (hypothalamus-pituitary-adrenal)
is functioning at a lower
than normal level in ME/CFS. Oddly enough, the HPA axis is designed to turn
itself off. Every time
cortisol – the endpoint of the HPA axis - is released, it inhibits further
HPA axis activity. The body
does this because the stress response – which cortisol triggers - is too
potent a reaction to have it
turned on all the time.
One theory suggests that this ‘negative feedback response’ has gone too
negative in chronic fatigue
syndrome (ME/CFS). It posits that CFS patients turn off their stress
response too quickly; every time
the HPA axis ramps up, it shuts itself down before it can effectively
respond to the challenge at
hand. This could make it difficult for patients to raise the energy
needed to engage in all
sorts of ‘stressful’ activities.
These UK researchers gave the participants a drug (prednisolone) designed to
test how fast their HPA
axes shut down. A greater fall in chronic fatigue sydndrome (ME/CFS) patient’s cortisol levels would
suggest that they were
turning off their stress response more quickly than normal.
The Findings These researchers found that ME/CFS patients did shut down their ‘stress
response’ more quickly than
normal; the prednisolone suppressed cortisol output by about 20% more in
ME/CFS patients (p<.0001)
than in the healthy controls. This also suggests upregulated GR/MR (glucocorticoid/
mineralocorticoid) receptor
activity was present in
the disease.
These UK researchers noted that enhanced negative suppression of cortisol is
also found in several
diseases sometimes associated with chronic fatigue syndrome (ME/CFS) such as
post-traumatic stress
syndrome, burnout syndrome and chronic pelvic pain.
Early Life Stress and Chronic Fatigue Syndrome (ME/CFS)
Van Den Eede F, Moorkens G, Hulstijn W, Van
Houdenhove B, Cosyns P, Sabbe BG, Claes SJ. 2007. Combined dexamethasone/corticotropin-releasing
factor test in chronic fatigue syndrome. Psychol Med. 2007 Sep ;1-11
As in the previous study, these Belgian researchers also stressed the HPA
axis to see how it
responded, but they dug a bit deeper. They used a different HPA axis
stressor (dexamethazone) and
examined whether early life stress influenced how well the HPA axis was
functioning. They looked at
early life stress because some theories suggest that high rates of early
life stress (ELS) may

predispose people to ME/CFS.
Study Findings: Interestingly, the rates of ELS in the ME/CFS and control
group did not differ
significantly.
They found that, yes, ME/CFS patients as a whole did appear to be turning
off their HPA axis more
quickly than normal. When they teased out the ME/CFS patients with ELS from
those without ELS they
found, contrary to expectations, that only the patients without ELS had
abnormal HPA axis functioning
(!); the HPA axis of the patients with ELS appeared to be working just fine.
This suggests, of
course, that ME/CFS patients with early life stress are a different subset
of patients than those
without early life stress.
Early Life Stress, the CDC and Chronic Fatigue
Syndrome (ME/CFS) – One CDC study suggested that people
who experience ELS are more prone to develop chronic fatigue syndrome (ME/CFS) than those who do
not. This Belgian study, ironically enough, suggests that ME/CFS patients with
early life stress have a normal stress response and it’s the ME/CFS patients without early life
stress that have the abnormal
stress response. Given this study’s findings one could make a case that
ME/CFS patients with ELS have been obscuring the magnitude of the stress response related problems in
those ME/CFS patients without ELS.
This study follows a string of nervous system studies by Dr. Natelson that
suggest ME/CFS patients
with mood disorders differ from patients without those difficulties. What’s
really intriguing and on
the surface paradoxical about these studies is that they’ve found more
abnormalities in ME/CFS
patients without these mood problems/psychological trauma than in those with
them.
Take Away Points
ME/CFS patients do appear to shut down their stress response more quickly
than normal. This could account for the low cortisol levels sometimes found and contribute to their
post-exertional fatigue and immune problems.
ME/CFS patients did not have statistically higher rates of early life stress
than the healthy controls.
Patients with early life stress had normal HPA axis readings while patients without
early life stress had abnormal ones. This and other studies suggest that patients with mood
disorder/psychological trauma may have a different type of ME/CFS than those
without those problems.

Success Snapshot
Testing found that one woman had low levels of progesterone - a steroid

cortisol and which plays a role in the menstrual cycle, pregnancy, etc. Her
endocrinologist had no suggestions but her gynecologist did; she put her on progesterone and six
months she was still reporting significantly improved energy.
(they believe this is
important); they’re using the ‘Empirical Definition’ not the standard 1994
International (Fukuda)
definition to gather their patients; and they’re measuring fatigue, symptoms
and disability according
to standardized measures.
(Oddly enough they don’t refer to the ‘Empirical Definition’. They simply
state they used the
‘standardized reproducible criteria’ recommended by the International Study
Group (ISG) which was
based on the 1994 definition. This suggests that the new definition simply
quantifies the 1994
definition which steps over the fact that the new definition greatly
discounts fatigue and appears to
focus more on emotional issues. It also ignores the fact that the final
definition was developed by a
small in-house group of CDC researchers and that some of the members of the
ISG were appalled by the
new definition; it is not simply a quantification of the International
Definition)
Findings – This study found low morning cortisol levels in women but not in
men with ME/CFS compared
to healthy controls. The finding that only females had low morning cortisol
levels was new and
interesting since it could help explain why more women have this disease
than men. When they examined
symptom, fatigue and disability scores they found that the low morning
cortisol was correlated with
physical fatigue.
Reduced Adrenal Capacity? For the first time that I can remember the CDC
suggested that the low
cortisol levels might reflect reduced adrenal capacity presumably because
studies suggest that early
morning cortisol in part reflects adrenal capacity. Most of the speculation
regarding cortisol thus
far has focused on damage higher up – at the hypothalamus or pituitary or in
the brain's signals to
them but here the CDC is suggesting that the problem may lie at the last
rung of the axis – the
adrenals. This mirrors Baschetti’s controversial proposal that ME/CFS is an
Addison’s-like disease and
these researchers noted that ME/CFS shares many symptoms with Addison’s
disease.
Dr. Reeves, citing the less than spectacular results of a short-term trial
of hydrocortisone (the standard treatment for Addison's disease) does not
recommend cortisol supplementation in ME/CFS. (This leaves us with the
odd situation of Dr. Reeves not recommending adrenal hormone supplementation
(hydrocortisone)for what he suggests may be an adrenal deficiency and
Dr. Holtorf recommending adrenal hormones ( bio-identical hormones) for a
problem he believes originates in the hypothalamus.)
Cortisol – An Overstudied Hormone?
Because chronic stress can affect cortisol (and HPA axis
functioning) it’s possible that the lowered cortisol levels in ME/CFS simply
reflect the very
stressful nature of their lives and have nothing to do with triggering the
disease. (We should know
more about this soon; Dr. Taylor is measuring cortisol levels as
mononucleosis patient’s lapse into
ME/CFS. She should be able to tell us when the low cortisol levels appear in
patients with an
infectious trigger.)
While this study confirmed again that the HPA axis part of the stress
response is underactive in
ME/CFS, it also cast doubt on how important low cortisol is. The paper
started off noting that low
cortisol is associated with fatigue, sleepiness, malaise and muscle and
joint pain, but, of the
fifteen different scales measured, the low cortisol levels were only
significantly correlated with
physical fatigue – not an impressive result for such a supposedly important
agent.
The ability to measure symptoms and disability is a big benefit of the
empirical definition.
Ironically, this time it suggested a major emphasis of the CDC’s program may
not be so major at all.
(But hold on – a recently released study suggests cortisol may play a bigger
role than this study
suggests).
Takeway Points
Low morning
salivary cortisol levels in women with ME/CFS but not men suggest cortisol
may play a special role in women
The CDC suggests ME/CFS may be an Addison’s-like disease that reflects low
adrenal capacity.
A analysis of symptoms suggests cortisol contributes to the physical
fatigue in the disorder but not other symptoms
Conclusions: Aside from the agreement that low
cortisol levels do play a role in some ME/CFS patients illness there seems
to be little consensus on how big a role they play or how to fix them. One
side, lead by Drs. Holtorf and Teitelbaum believes bio-identical hormone
supplementation is often an essential component of a patients treatment
regime and have some evidence that it works. Another side which includes the
CDC but also some other prominent physicians are strongly against even low
dose hormonal supplementation unless there is clear evidence of a
significant hormonal deficiency. ME/CFS patients and their physicians will
have to decide how to proceed.
