National Geographic TV: Hello...my name is Jon Maas and I am
producing a medical show for National Geographic Television, and we are
doing a segment on Cushing’s Syndrome. We
are looking for a patient with EXTREMELY visible symptoms of Cushing’s that
would like to share their story.
My National Geographic/Authentic Entertainment show is called “Inside
Extraordinary Humans.” It is a science-heavy show that explores the inner
workings of humans with unique body shapes and sizes. We are hoping to do a
segment on Cushing’s syndrome – the cause, the symptoms and the
treatment.
Once again, we are hoping to find a patient with VISIBLE symptoms of
Cushing’s syndrome who is willing to be on camera with his/her doctor. We
are hoping for subjects that because of Cushing’s, could qualify as “Obese”
or even “Morbidly Obese.” I understand that many Cushing’s sufferers exhibit
moderate, little or even no weight gain, but the National Geographic
executives have told us that they want to do a story on someone who has put
on quite a bit of weight. We then want to film that patient in the process
of treatment. If you or someone you know has (or had) Cushing's
Syndrome -- and has an amazing story that you want to share with the world -
I look forward to hearing from you!
Please e-mail ASAP (we are going to begin filming quite soon):

Request for Input from the NIH on Trans-NIH Initiatives
Thank you for your support!
The NIH is seeking input from the scientific community, health
professionals, patient advocates, and the general public about
innovative and cross-cutting initiatives that will improve and
accelerate biomedical research and its impact on the health of the
nation. Collecting these ideas is an initial step in the process of
identifying a new cohort of “Roadmap” trans-NIH strategic initiatives
for fiscal year 2008.
This idea-gathering phase has also included obtaining input from
scientist consultants and the NIH Institutes and Centers. This RFI provides
an opportunity for respondents to submit their own ideas and to view ideas
nominated to date. The NIH expects to spend $30–50 million per year from
within the currently projected Roadmap budget for approximately 5–8 new
5-year (or in exceptional cases up to 10-year) initiatives.
More information on this request can be found at:
http://grants.nih.gov/grants/guide/notice-files/NOT-OD-07-011.html.
Future requests for public input will be available at

Context: Hesx1 is one of the earliest homeodomain
transcription factors expressed during pituitary development.
Very few HESX1 mutations have been identified in humans;
although in those cases the disease phenotype shows considerable
variability, all but one of the patients display an ectopic
posterior pituitary and/or optic nerve abnormalities.
Objective: The objectives of the study were to describe the complex phenotype associated with the panhypopituitarism of
two unrelated Italian patients who, at birth, presented with
hypoglycemic seizures and respiratory distress complicated by
shock, in a familial context of neonatal death in one family and
spontaneous miscarriage in both families and to identify the
molecular basis of this unusual syndrome.
Main Outcome Measures: Magnetic resonance imaging of the pituitary region, study of HESX1 gene and transcripts, and assessment of the ability of mutated HESX1 proteins to repress transcription were measured.
Results: Magnetic resonance imaging examination showed an anterior pituitary aplasia in a flat sella turcica and a normally located posterior pituitary in both patients. A constellation of
extrapituitary developmental defects were found in the two
patients, but without any optic nerve abnormalities. Sequencing
of HESX1 exons and their flanking intronic regions
revealed two different homozygous mutations. A frameshift
(c.449_450delAC) was identified in one case, whereas the other
patient carried a splice defect (c.357 + 2T>C) confirmed by the
study of HESX1 transcripts. If translated, these mutations
would lead to the synthesis of truncated proteins partly or
entirely lacking the homeodomain, with no transcriptional
repression, as shown by their inability to inhibit PROP1 activity.
Conclusions: These observations reveal two novel HESX1
mutations in a so-far-undescribed disease phenotype characterized
by a life-threatening neonatal condition associated with anterior pituitary aplasia, in the absence of ectopic posterior pituitary

Abstract
Classroom discussion of scientific articles can be an effective means of teaching scientific principles and methodology to both undergraduate and graduate science students. The availability of classic papers from the American Physiological Society Legacy Project has made it possible to access articles dating back
to the early portions of the 20th century. In this article, we
discuss a classic paper from the laboratory of Dr. James O. Davis
on the regulation of aldosterone synthesis from the adrenal zona
glomerulosa cell. Dr. Davis has conducted much of the seminal
research investigating the renin-angiotensin system and the
regulation of aldosterone release by angiotensin II. In addition
to a characterization of the effects of ACTH on aldosterone
regulation, this study is useful for discussing the basic
principles of negative feedback pathways of the hypothalamic-pituitary axis. This study also provides examples of early bioassay techniques for the detection of angiotensin II and of the importance of quantitative measurements when investigating physiological responses. Three figures and one table are reproduced from the original article along with a series of discussion questions designed to facilitate discovery learning.

Changes in thrombospondin-1 levels in the endothelial cells of the anterior

Abstract
Thrombospondin-1 (TSP-1), a multifunctional matrix glycoprotein, has been
shown to control tumor growth by inhibiting angiogenesis in various tissues.
However, the role of this glycoprotein in pituitary angiogenesis is not well
studied. In this report, we determined the changes in the production and
action of TSP-1 on endothelial cells in anterior pituitary following
estradiol treatment, which is known to increase prolactin-secreting tumor
growth and vascularization in this tissue. We showed that TSP1
immunoreactive protein is distributed in the anterior pituitary,
particularly in the endothelial cells. Estradiol treatment for 2 and 4 weeks
decreased the total tissue immunoreactive level of TSP1 as well as the
endothelial cell specific immunoreactive level of this protein in the
anterior pituitary. The steroid treatment also decreased the protein levels
of TSP1 in anterior pituitary tissues and in purified pituitary endothelial
cells in primary cultures. Determination of the effects of TSP-1 on
proliferation and migration of pituitary-derived endothelial cells in
primary cultures elucidated an inhibitory action of TSP-1 on this vascular
cell functions. These results suggest that locally produced TSP-1 may
regulate estrogen angiogenic action on the pituitary.

Hemochromatosis (Iron Overload) Affects the
Pituitary
TOO MUCH IRON RUSTS THE LIVER
DEAR DR. DONOHUE: My husband died at age 62 of liver cancer. I have a
feeling that it might have been caused by the undiagnosed complications of
hemochromatosis. I think this is so because three of my five children over
the age of 40 have just been diagnosed with hemochromatosis and are
presently under treatment for it. Could there be a connection between it and
my husband's cancer? -- P.F.
ANSWER: Hemochromatosis (HE-moe-CROW-muh-TOE-suss) is an inherited disorder
with an unfortunately unusual name that makes people think it's a rarity. It
is not. It has to do with an inappropriate absorption of iron.
Humans have a built-in mechanism that allows the digestive tract to absorb
only the amount of iron that is lost every day. People with hemochromatosis
don't have this mechanism. They absorb far too much iron, which deposits in
many tissues and organs. The liver is the principal organ affected, and the
iron rusts it, so to speak.
Excess liver iron leads to cirrhosis. Iron in the heart brings on heart
failure. In the pancreas it causes diabetes. Joints filled with iron become
arthritic. Iron infiltrating the skin turns it a bronze color. Iron can
invade the testicles and the pituitary gland and greatly damage them.
Although the defect is present from birth, signs don't develop until
sometime between 40 and 60. If the illness is diagnosed before organ damage
takes place, treatment by removing blood keeps organs healthy. Blood is the
body's storehouse of iron.
Liver cancer can be a consequence of hemochromatosis. It happens to about 30
percent of those hemochromatosis patients who develop cirrhosis.
Since hemochromatosis is a genetic illness, all your children should be
checked so that early treatment can keep organs healthy.

Original Case Definition
Patients who have developed large areas of
hardened skin with slightly raised plaques, papules, or confluent papules;
with or without pigmentary alteration and/or with biopsies showing
increased numbers of fibroblasts, alteration of the normal pattern of collagen
bundles seen in the dermis, and often increased dermal deposits of mucin.
NSF…what is it?
Nephrogenic Systemic Fibrosis (NSF), also known as nephrogenic fibrosing
dermopathy (NFD), is a condition that, so far, has occurred only in people
with kidney disease. There is no convincing evidence that NSF is caused by a
medication, a microorganism, or by dialysis. There have been no cases
identified prior to early 1997. At this point it appears NSF is a systemic
disorder with its most prominent and visible effects in the skin. For this
reason, Nephrogenic Systemic Fibrosis has been suggested as an equivalent
terminology in those previously diagnosed with NFD,
and is preferred in that it more accurately
reflects our current understanding of the disorder.
Neither the duration of kidney disease nor its underlying cause are related to
the development of NSF. Some patients with NSF develop skin tightening in the
earliest stages of kidney disease, and others may have had kidney disease for
years. Specific triggers for the development of NSF are still being
investigated. Recent reports have strongly
correlated the development of NSF with exposure to gadolinium-containing MRI
contrast agents. Further information from the US Food and Drug Administration
regarding this observation can be found here: (http://www.fda.gov/cder/drug/advisory/gadolinium_agents.htm).
GE healthcare, one manufacturer of
gadolinium-containing MRI contrast, has issued an informational announcement
at: (http://www.amershamhealth-us.com/omniscan/safety/index.html).
NSF appears to affect males and females in approximately equal numbers. NSF
has been confirmed in children and the elderly, but tends to affect the
middle-aged most commonly. It has been identified in patients from a variety
of ethnic backgrounds and from North America, Europe, and Asia.
Besides kidney disease, conditions that may be associated with NSF include
coagulation abnormalities and deep venous thrombosis, recent surgery
(particularly vascular surgery), recent failure of a transplanted kidney, and
sudden onset kidney disease with severe swelling of the extremities. It is
very common for the NSF patient to have undergone a vascular surgical
procedure (such as revision of an AV fistula, or angioplasty of a blood
vessel) or to have experienced a thrombotic episode (thrombotic loss of a
transplant or deep venous thrombosis) approximately two weeks before the onset
of the skin changes.
The associated conditions enumerated in
the preceding paragraph frequently justify the use of gadolinium-enhanced MRI
or MRA studies. Whether the recently announced association of NSF with
gadolinium exposure is the common denominator of all NSF cases is still under
investigation. A verifiable cause and effect relationship has not yet been
established, but active efforts to prove or refute this relationship are
underway. Two recent papers have verified
the presence of gadolinium in the tissue of some patients with NSF, however,
the study designs do not allow for determining whether the gadolinium caused
the NSF
(free article download #1)(free article download #2).
Symptoms and Signs
Patients with NSF describe swelling and tightening of the skin, usually
limited to the extremities (images),
but sometimes involving the trunk. The condition may develop over a period of
days to several weeks. In many cases, the skin thickening inhibits the flexion
and extension of joints, resulting in contractures. Severely affected patients
may be unable to walk, or fully extend the joints of their arms, hands, legs,
and feet. Complaints of muscle weakness are common.
Approximately 5% of patients have a rapidly progressive (fulminant) course.
The skin changes may start as reddened or darkened patches, papules, or
plaques. In time, the skin may feel “woody” and the surface may resemble the
texture of the peel of an orange. Patients may experience burning, itching, or
severe sharp pains in areas of involvement. Radiography may reveal
calcifications of the soft tissue. Deep
"bone pain" has been described in the hips and in the ribs.
The skin lesions are commonly symmetrical, with zones between the ankles and
thighs most commonly involved, followed by involvement between the wrist and
upper arms. Hand and foot swelling with blister-like lesions has also been
reported. Some patients have reported yellow papules or plaques on or near the
eyes. Rapid, new onset fluctuating
hypertension of unknown cause has been described prior to the onset of the
skin lesions.
Treatment options
While there is no consistently successful treatment for NSF, improving
renal function (due to any modality) seems to slow or arrest NSF (and in many
cases allows for gradual reversal of the process over time).
Critical assessment of the effects of any investigational therapy requires
careful attention *and reporting* of the patient's renal function
during therapy. Investigational therapies that show objective improvement
in the setting of worsening or stable chronic renal failure should be
targeted for further investigation. Therapies that show improvement of NSF
while renal function is improving may or may not be contributing to the
observed improvement. Given the recent
association of NSF with gadolinium administration, any reports of
investigational therapies should also clearly indicate whether gadolinium was
administered during the therapeutic evaluation, and whether there was an
identifiable clinical change in the patient's disease.
Treatments that have been tried and continue to be investigated include:
Oral steroids (prednisone): Has had some efficacy in doses of 1 mg/kg
po qd. Patients with concurrent diabetes should be aware of the risks of
hyperglycemia while taking this medication. All patients should be aware of
the possibility of gastrointestinal ulceration while taking prednisone.
In addition, osteoporosis is often accelerated while taking this medication,
sometimes creating a rapid calcium-wasting state. It is not clear whether the
prednisone is affecting the cutaneous disease, or the renal disease,
but it does seem to work in a subset of patients.
Topical Dovonex (under occlusion):
So far, responses have been anecdotal and largely subjective. Some patients
report improvement in localized disease.
The combination of occluded dovonex and clobetasol with vascular compression
stockings has reportedly been of benefit.
Extracorporeal photopheresis (ECP): A recent article describes three
patients in Europe who responded with softening of plaques after several
courses of ECP. Each of these patients had no improvement in renal function
during the treatment. All three of these patients had had NSF for less than
one year. This report corroborates other anecdotal reports in the US that
photopheresis is helpful in a subset of patients. Experience at Yale suggests
that patients with longstanding NSF (arbitrarily set at one year) may not
respond to this modality. This treatment is currently under investigation,
although no formal trials are yet offered. Some insurance carriers are
receptive to covering a trial of therapy, but in the event coverage cannot be
secured, be advised that therapy is exceedingly
expensive. Many patients and providers have reported that Medicare has
provided coverage for ECP in recent cases.
Plasmapheresis: One study from Loma Linda University (ref
12) reported improvement in three patients with liver/kidney transplant.
Two of these patients were noted to have
concurrent improving renal function. It is unclear what contribution improving
renal function may have had in the overall clinical improvement. Nevertheless,
anecdotally, some persons have reported slight improvement following
plasmapheresis. Several others have been reported who noted no improvement at
all.
Cytoxan: Anecdotally, this medication has shown no improvement in a
number of NSF patients.
Thalidomide: There are no formal reports on the success of this medication in NSF. However, some patients have
reported subjective improvement. Long term tolerance of the drug may be an
issue, however. There have been two
reports among Registry patients of development of NSF in patients already
taking thalidomide for other medical problems.
Ultraviolet therapy: I am aware of anecdotal use of PUVA, but have heard no reports of success.
Article
38 discusses the use of UVA-1, evidently beneficial in the single case in
this report. PUVA in combination with
Soriatane and prednisone has been anecdotally helpful in two patients.
Physical therapy (PT): Some patients have reported that
physical therapy, in particular, swimming, may be helpful in slowing the
progression of joint contractures. There is no contraindication to PT, and the
definite potential up-side suggests that PT should be pursued whenever possible.
Deep massage has been reported to be of benefit.
Pentoxifylline (PXF): A recent report describes two NSF patients who
received 1200 mg per day of oral pentoxifylline (ref
57). Both patients stabilized, and the one with less severe disease
improved somewhat. The use of PXF is theoretically justified as it has known
antifibrotic activity (thought to be at least partially related to TNF alpha
antagonism). In addition, PXF is known to improve red blood cell flexibility,
and therefore to improve circulation. As thrombosis seems to be an inciting
event for many NSF patients, this mechanism could also be partially
responsible for the improvements noted clinically. Many more patients will
need to be treated to further evaluate the efficacy of this drug.
High Dose Intravenous Ig Therapy: Reference number
25
describes a patient who showed objective improvements with one cycle of
therapy with this medication. Further improvement with additional cycles was
not observed. No comment was made regarding the renal status of the patient
while receiving this therapy. I have heard anecdotal information suggesting
this therapy has been helpful in one other patient with NSF. Additional
anecdotal data have been less promising.
Renal transplantation: Several patients have improved significantly
with a return to normal kidney function (either as a result of transplantation
or medical therapy). In other cases, kidney transplant has resulted in no obvious improvement
of the lesions, even with a fully functioning, successfully transplanted
organ. I am aware of no reason--at this time--that NSF patients should be
excluded from receiving a renal transplant. There are many potential benefits
to receiving a transplanted kidney, however, and further elaboration about
this decision in the setting of NSF is discussed in reference
52.
As many NSF patients have underlying hypercoagulable states, careful testing
for coagulation disorders is recommended prior to transplantation to help
reduce the incidence of unexpected and detrimental coagulopathies.
Magnetic resononce angiography with gadolinium-containing agents should be
avoided in NSF.
Prognosis
As NSF is a rare, relatively recent diagnosis, the natural history of the
disease is not well understood. Some patients report a gradual improvement in
mobility and slight softening of the skin over time. Complete spontaneous
healing in a patient with ongoing kidney disease has not yet been reported.
Several patients with NSF have died as a result of complications of their
kidney disease or transplant surgery. One patient, who elected to discontinue
dialysis, had widespread fibrosis involving the diaphragm, psoas muscles,
proximal esophagus and intimal areas of vessels of the kidney and lungs.
As mentioned above, some patients with NSF (estimated at 5% or less) have an
exceedingly rapid and fulminant disease course that may result in death. NSF,
by itself, is not a cause of death, but may contribute to death
by restricting effective ventilation, or by restricting mobility to the point
of causing an accidental fall that may be further exacerbated by fractures and
clotting complications.
Suspected pathogenesis
Recent investigations suggest the cell responsible for the fibrosis seen in
NSF is a recently characterized cell involved in wound healing and tissue
remodeling. This cell--a circulating fibrocyte (CF)--is distinct from a
fibroblast in that it has a CD34/procollagen dual positive profile and is
blood-borne. In NSF, CFs are thought to leave the circulation (possibly
aberrantly, or as a result of passive diffusion in fluid overload states) and
differentiate in the dermis into cells that functionally and histologically
resemble normal dermal fibroblasts. Because of the presence of these
circulating cells, NSF can be considered a systemic disorder. Several reports
have verified the presence of fibrosis in other organs in NSF, but whether the
fibrosis is more likely in these patients than in the general population has
not been formally verified.
The factors responsible for differentiation of CFs into terminal
fibroblast-like cells are not clear, but are likely directly related to the
underlying function of the kidneys. Because of the close association of
surgery and thrombosis in most cases of NSF, thrombosis and/or
endothelial damage may be partially responsible for the initiation of a series
of events that culminates in NSF.
Noting the common preceding events of vascular surgery and thrombosis (as well
as brain tumors in a small number of NSF patients--ref
17), we have been actively investigating the possibility that radiographic
contrast agents might be a trigger in some NSF patients. One common
denominator in all of these recognized comorbidities is the frequent use of
contrast agents for angiography (detecting clots, planning surgery, and
evaluating the vascularity of brain neoplasms). We had noted that contrast
agents had been used (and sometimes had been temporally related to disease
onset) in several patients. We elaborated upon the possibility that
peripherally deposited radiographic contrast might be a target for circulating
fibrocytes in a recent publication (ref
62).
Interestingly, a group in Austria working along similar lines simultaneously
published a report (ref
57) that the MRI angiographic contrast agent known as "Gadolinium" had
been used in all NSF patients in their study group. Those patients who had
renal disease and were also exposed to Gadolinium but did not develop
NSF were not acidotic at the time of their studies (those who developed NSF
were, in fact, acidotic). A comparison of medications revealed no single
medication could account for the findings in all patients (including the use
of angiotensin converting enzyme inhibitors).
Another recent and larger scale study
from Denmark (ref
74) also associated the use of gadolinium-containing contrast agents with
NSF onset, although the acidosis suspected as being a facilitator in the
Austrian study (above) was not observed. At this time it is not clear whether
systemic acidosis is an independent risk factor for NSF, or whether it is
etiopathogenic in any sense.
Given these data, it would be most prudent
to recommend that the use of gadolinium-containing contrast agents be excluded
to the greatest extent possible in patients with renal disease until these
observations can be confirmed and clarified. A formal announcement from the
FDA is present at: (http://www.fda.gov/cder/drug/advisory/gadolinium_agents.htm).

The International Center for NFD/NSF Research (ICNFDR)
The ICNFDR is a new appellation for a
collaborating group of researchers based at Yale University who are involved
with NSF research. The team consists of physicians and basic science
researchers from several disciplines who have committed to working together in
the search for the cause, treatment, and eventual eradication of NSF. The
heart of the project is the NSF Registry (see below) a direct offshoot of the
original CDC investigation that began in California several years ago.
Until recently, the Centers for Disease
Control have not been involved in NSF investigation for several years.
However, the CDC has recently completed a site investigation, and when the
data are released, new information will be posted. For now, continue to
contact us as noted below. In addition, cases reported to the Food and Drug
Administration are not necessarily fully reported to the ICNFDR, and vice
versa (due to privacy constraints in both institutions and differing
missions). Ideally, all cases should be reported to both organizations.
The goals of the ICNFDR are as follows:
1) Identification and diagnosis of
individual cases of NSF (contacts via physicians and patients)
2) Informing the public and physicians
about NSF (website, publication, lectures)
3) Researching the pathophysiology of NSF
(lab studies, clinical studies, collaboration)
4) Clinical trials of promising therapies
In the next few months, this website will
transition into the new ICNFDR website at Yale University. The official web
address for the site is currently
http://www.icnfdr.org .
This new address is valid now, and will remain valid after the move to the
Yale server.
The NSF Registry
Since NSF is a rare condition (with over 215
cases identified in the Registry so far) it is difficult to make
generalizations about the disease. The Centers for Disease Control and
Prevention (CDC) co-investigated cases of NFD/NSF with doctors from the
University of California in San Francisco when the disorder was first
identified. Since then, the investigative effort has moved to Yale University.
Dr. Shawn Cowper is currently in charge of confirming and investigating cases
of NSF.
The NSF Registry is a project that collects and organizes information about
patients with NSF from all over the world. The goal of the project is to
identify factors that may be related to or causative of NSF. In addition,
information about treatment successes and failures will be collected in order
to try to find effective therapies and design future medication/therapy
trials. The summary of information you see on this website is the result of
contributions of data to the NSF registry so far. The Registry is funded
through several mechanisms (internally, through
donations,
and through grant monies provided by the General Clinical Research Center at
Yale University).
In order to ensure that the data collected in the registry are accurate, it is
important to first confirm the diagnosis. Several conditions resemble NSF, and
these must be excluded from the data collection effort. If you suspect you or
a loved one may have NSF, please have your physician contact Dr. Cowper as
noted below.
If you have questions about NSF not answered by this information sheet, please
forward them to Dr. Cowper at the e-mail address below. As you could imagine,
the effort is quite complex and time consuming. Please be patient, your
questions will be answered.

Abstract
The objective of this study was to determine the effects of manipulating
glucocorticoid negative feedback on acute ACTH and corticosterone responses to
corticotrophin-releasing hormone (CRH) injection in 7-day old rats exposed to
normoxia or hypoxia from birth. Chemical adrenalectomy was achieved with
aminoglutethimide, and glucocorticoids were replaced with a low dose of
dexamethasone. Hypoxia per se increased basal plasma corticosterone and
attenuated the plasma ACTH response to CRH. Aminoglutethimide per se decreased
plasma corticosterone and strongly increased basal plasma ACTH and anterior
pituitary POMC gene expression. Dexamethasone partially attenuated elevations
in basal plasma ACTH due to aminoglutethimide in both normoxic and hypoxic
pups, but inhibited anterior pituitary POMC expression and CRH-induced plasma
ACTH only in hypoxic pups. Despite this inhibition, hypoxic pups treated with
both dexamethasone and aminoglutethimide still exhibited a significant CRH-induced
increment in plasma ACTH that was lacking in hypoxic pups not treated with
either dexamethasone or aminoglutethimide. We conclude that ACTH responses to
acute stimuli in hypoxic neonatal rats are prevented by ACTH-independent
increases in corticosterone rather than by intrinsic hypothalamic-pituitary
hypoactivity.

NIH ANNOUNCES AWARDS IN CHRONIC FATIGUE SYNDROME RESEARCH
The Office of Research on Women's Health (ORWH) and the Trans-NIH
Working Group for Research in Chronic Fatigue Syndrome (CFSWG) of the
National Institutes of Health (NIH) are pleased to announce seven (7)
awards in Chronic Fatigue Syndrome (CFS) research. The proposed studies
will help researchers understand how the diverse symptoms in CFS are
related to the interactions between the immune and neurological systems
-- an important step towards developing effective treatments for a
disabling condition.
The awards were funded by ORWH, Office of the Director, and four member
institutes: The National Institute on Alcohol Abuse and Alcoholism
(NIAAA), the National Institute of Environmental Health Sciences
(NIEHS), the National Institute of Arthritis Musculoskeletal and Skin
Diseases (NIAMS), and the National Institute of Neurological Disorders
and Stroke (NINDS).
Katherine Light, Ph.D., University of Utah, St. Lake City, Utah, plans
to first explore in humans the suggested mechanisms for the perception
of pain and fatigue in CFS by assessing repeated patterns in the immune
and neurological systems that are present before, during and immediately
after mental and physical exertion. There is a possibility that findings
will lead to the development of a biomarker for CFS. Her second pilot
study will focus on identifying family risk patterns in CFS using the
Utah Family Data Base (large genealogy data base) to explore the
familial/genetic component of CFS. Identifying a genetic predisposition
to CFS will assist in the development of more effective medications.
Theoharis Theoharides, M.D.,Ph.D., Tufts University, Boston,
Massachusetts, will explore the relationship of human mast cells
(molecules released in stress) in the brain, not only in explaining the
development of CFS but also in explaining the effects of antidepressants
in relieving symptoms in CFS patients. Dr. Theoharides will examine the
cellular changes that explain CFS symptoms using three different classes
of antidepressants: tricyclic, serotonin uptake inhibitors and
bupropion. Future studies will build on these findings to develop
clinical trials of select antidepressants or other molecules that
inhibit CFS.
Mary Ann Fletcher, Ph.D., University of Miami, Miami, Florida, plans to
study the role of specific peptides: neuropeptide Y (NPY) and
dipeptidyl-peptidase (CD26) in the development of CFS. These peptides,
formed from amino acids (the basic building blocks of the body that are
essential in combating illness), regulate many physiological and disease
processes in the cardiorespiratory, immune, nervous and endocrine
systems. This study will also examine aspects of the relationship
between different levels of peptides and the severity of CFS symptoms
and may lead to the development of biomarkers.
Dianne Lorton, Ph.D. at the Sun Health Research Institute in Sun City,
Arizona, will establish a tissue bank to make brain and spinal cord
tissue available to study CFS/FM (fibromyalga). She has gathered an
interdisciplinary research team that will determine the extent to which
chronic pain in these patients is associated with glial (support cells
of the nervous system) activation and resulting cytokine production
(compounds essential to engage the immune response). While studies in
rodents have shown this activation leads to inflammation and chronic
pain, Dr. Lorton will test the extent that this process is involved in
humans in order to target mechanisms to treat the chronic pain
associated with CFS.
James Baraniuk, M.D., Georgetown University, Washington D.C., has found
that despite its diverse clinical syndromes, the CFS proteome (the
entire group of proteins in an organism or system) is the same,
suggesting a strong relationship with malfunctioning of the central
nervous system. Dr. Baraniuk developed the first predictive model of CFS
based solely on objective data and he now proposes to recruit a new
group of CFS and Healthy Control subjects to determine if the proteins
in their cerebrospinal fluid will be a predictive marker of the spectrum
of CFS symptoms. There is a high probability that these methods and
markers will be of diagnostic value and will be useful for assessing
changes over time in disease severity and treatment effects.
Michael Antoni, Ph.D., at the University of Miami, Miami, Florida, has
demonstrated the positive effects of participation in group cognitive
behavioral stress management (CBSM) on quality of life, perceived
stress, fatigue, memory, muscle pain and post-exertional malaise for CFS
patients compared to those in a control condition. Many CFS patients are
too debilitated to attend regular therapy sessions. Therefore, in the
present study, he will test the physiological effects of a
telephone-based cognitive behavioral stress management intervention to
illuminate CFS patients' neuroimmune mechanisms in relation to stress
and stress management. The correlation of the neuroimmune parameters and
the behavioral components promises to identify a biologically useful
marker for CFS.
Italo Biaggioni, M.D. at Vanderbilt University in Nashville, Tennessee,
will explicate the role of the sympathetic nervous system (SNS) in the
cardiovascular and inflammatory abnormalities in the subset of patients
with postural tachycardia (POTS) -- increase in heart rate and often
decrease in blood pressure on standing. Preliminary studies indicate a
relationship between the mechanisms underlying POTS and CFS symptoms.
Dr. Baggioni will test these hypotheses in a comprehensive set of
experiments with appropriate controls.
"These innovative, interdisciplinary studies to help us better
understand the role of the central nervous system in the origin and
development of CFS; represent efforts of the Trans-NIH Working Group for
Research on Chronic Fatigue Syndrome, chaired by the ORWH, to expand
interest in CFS research. I am excited that these efforts could lead to
major advances in understanding the disease processes of CFS and that
they may also provide diagnostic biomarkers that can be used to measure
treatment effects. These studies may also help us understand why some of
the known treatments are effective and lead to the development of newer
and more targeted remedies," stated Dr. Vivian W. Pinn, M.D., Director
of the ORWH.
