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 http://getinvolved.nih.gov/public_comment.asp.

Please forward this information to anyone else who may find it useful.

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.

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 com
mon. 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.

The Office of Research on Women's Health (ORWH), Office of the Director, National Institutes of Health (NIH) serves as a focal point for women's health research at the NIH. For more information about NIH's Office of Research on Women's Health, visit <http://orwh.od.nih.gov/>.

The National Institutes of Health (NIH) - The Nation's Medical Research Agency - is comprised of 27 Institutes and Centers and is a component of the U. S. Department of Health and Human Services. It is the primary Federal agency for conducting and supporting basic, clinical, and translational medical research, and investigates the causes, treatments, and cures for both common and rare diseases.
