and some in person) so many wonderful people! Without your hard work, none of
this would be possible! Give me a "M", give me an "A", give me a "R", give me a
"Y"- "MARY!!!!!" I am now post op, confirmed cyclical pituitary Cushing’s Disease. I had
pituitary surgery in April 2004, then a BLA in March 2006. I credit this board
with saving my life! From
JenS' bio Mary, I love it. Now we big kids can hunt Easter
eggs for a week! And while I have your attention, thank you so much for this
board. I have no idea where we would be without it. My family was close to
desinigrating from the stress of the last two years with my son sick. Now we are
healing even though we have no diagnosis yet. but have a more positive outlook.

Understanding Animal Behavior So We Can Understand Our Own By Dan Paskowitz Behavioral scientists have long sought to understand the detailed mechanisms
by which the brain, and the endocrine systems under its control, govern animal
behavior. In a paper from the March 1 issue of Nature, Japanese researchers have
described a pathway that appears to play a major role in social and reproductive
behavior in mice. The hormone oxytocin is made by neurons in the hypothalamus, a remarkable
part of the brain that regulates appetite, water balance, temperature control,
circadian rhythms and most of the body’s endocrine glands. The oxytocin-producing
neurons send processes to the pituitary gland, from which they release the
hormone. Oxytocin is known to promote uterine contraction and lactation, but has
also been implicated in a variety of sexual and social behaviors. The researchers focused on a protein expressed in the oxytocin-producing
hypothalamic neurons called CD38. The structure of this protein suggested that
it might play a role in the release of oxytocin. In mutant mice lacking the gene
for CD38, oxytocin levels were lower than normal in cerebrospinal fluid and
blood, but elevated in the hypothalamus and posterior pituitary, arguing for an
inability to secrete the hormone into circulation. Circulating levels of a
similar hypothalamic hormone were not affected, implying a specific abnormality
in the oxytocin system. The CD38 mutant mice grew normally and appeared to be generally healthy.
Various behavioral tests suggested that the mice had normal sensory and learning
abilities. However, the mutant mice exhibited several changes in social
behavior. Males displayed a defect in social memory. Unlike normal mice, they
always reacted to female mice as if meeting them for the first time, even after
multiple encounters with the same individual. Mothers appeared to be less
interested in nurturing their pups. When normal mothers were placed at the
opposite side of a cage from their pups, they retrieved the pups quickly and
crouched over them to keep them warm. CD38 mutant mothers retrieved the pups
after a long delay and crouched over them only briefly. Injection of oxytocin restored normal behavior, implicating the deficit in
secreted oxytocin as the cause of the abnormalities in social behavior. Delivery
of a CD38 gene to the hypothalamus using viral vectors restored both oxytocin
secretion and normal social behavior. Further experiments elaborated the
mechanism of oxytocin release by CD38. These experiments may offer insight into some aspects of human behavior. One
of the cardinal features of autism and related developmental disorders is a lack
of normal social interaction. Some recent research has suggested that oxytocin
levels are decreased in autistic children, and that administration of oxytocin
can ameliorate some of their behavioral abnormalities, although it does not
restore normal social behavior. It is possible that abnormalities of CD38 or
other components of the oxytocin release machinery during development could play
a role in some patients with developmental disorders. Hollis-Eden Pharmaceuticals Announces Filing of IND for Phase I Clinical
Trial with Next-Generation Drug Candidate HE3286 in Metabolic Disorders -- Successful Safety Study Would Also Support
Potential Phase II Study with HE3286 in Autoimmune Disorders under Separate
IND Filing --
SAN DIEGO--(BUSINESS WIRE)--Hollis-Eden Pharmaceuticals,
Inc. (NASDAQ:HEPH) announced that it is filing today an
Investigational New Drug (IND) application with the U.S.
Food and Drug Administration (FDA) to begin a Phase I
clinical trial with its next-generation drug candidate
HE3286 for the treatment of metabolic disorders, which
include diabetes, obesity and dyslipidemia. The Phase I
trial program, designed to assess the safety of HE3286 in
healthy volunteers, could support both a Phase II study in
type 2 diabetes patients, as well as a Phase II study in
rheumatoid arthritis patients under a separate IND the
Company plans to file for autoimmune disorders later this
year. In preclinical studies, HE3286 has been shown to
regulate signaling pathways of inflammation common to both
metabolic and autoimmune disorders. As previously reported at a scientific conference on diabetes, HE3286
produced glucose lowering activity and increased insulin sensitivity when
administered orally in preclinical models of type 2 diabetes. The Company'>s
findings suggest that HE3286 may be the first in a new class of insulin
sensitizers with a novel mechanism of action, since it appears to regulate
the pro-inflammatory NF-kappa B pathway without acting on the PPARgamma
receptor, which is the target of insulin sensitizing drugs currently
prescribed today. By working through this new pathway, HE3286 appears in
preclinical studies to avoid the undesirable side effect of weight gain
commonly seen with these existing therapies. HE3286 is a derivative of an endogenous hormone the Company believes is
central to regulating glucose metabolism. Studies in rats fed with a diet
containing the parent hormone of HE3286 showed a reduction in the expression
levels of certain genes encoding key enzymes involved in glucose and
cortisol metabolism (e.g., PEPCK or 11beta-HSD1), an effect which should
lessen the severity or impact of type 2 diabetes on insulin resistance.
Through the application of medicinal chemistry, Hollis-Eden has developed a
chemical analog of that hormone, HE3286, a compound with a more
pharmaceutically suitable profile. In preclinical studies conducted to date, HE3286 administered orally to
genetically obese mice prone to diabetes (db/db model), significantly
(p <0.02) suppressed after 10 days the
progression of hyperglycemia typically observed in these animals. In an
animal model of diet-induced insulin resistance, HE3286 significantly (p < 0.01)
improved glucose handling in an oral glucose tolerance test (OGTT) when
compared to the control group, and at the end of the study was superior (p < 0.003)
to the active control (rosiglitazone). In addition, HE3286 demonstrated a
statistically significant (p<0.006)
reduction in fasting glucose values when compared to controls at days 14 and
29 of the study, and the activity was similar to the active control
(rosiglitazone) ( p<0.05). Additional evidence of improvement in glucose disposal by HE3286 comes
from a hyperinsulinemic/euglycemic clamp study, widely acknowledged as the
"gold standard" model to
measure insulin sensitivity in vivo. In this study, administration of
HE3286 to diabetic db/db mice markedly increased the glucose infusion
rate (GIR) required to maintain normal levels of blood glucose following an
intravenous infusion of a high dose of insulin. The GIR is a key parameter
used to determine the degree of insulin sensitivity in vivo, and its
increase following treatment with HE3286 indicates that this compound acts
physiologically as an insulin sensitizer in the diabetic state. In parallel experiments designed to elucidate the possible mechanism of
action of HE3286 to produce these metabolic effects, it was found that
HE3286 regulates the pro-inflammatory NF-kappa B pathway in cultured mouse
macrophages or human monocytes. This may be an important finding because
over the last several years reports in the scientific literature suggest
that chronic activation of inflammatory pathways such as NF-kappa B can also
lead to insulin resistance and may play a role in the progression towards
type 2 diabetes. HE3286 has also demonstrated a dramatic benefit in rodent models of both
initial-onset and established rheumatoid arthritis. Potential mechanisms of
action for HE3286 in this indication include regulation of NF-kappa B
and increasing the production of regulatory T cells, or Treg cells. Treg
cells play a key role in keeping the immune system from attacking the body
itself, and are being cited increasingly in the medical literature as
therapeutic targets in a range of diseases and disorders including
autoimmune conditions. "Filing an IND for HE3286 is a significant
milestone for Hollis-Eden and for our development program targeting
metabolism," stated Richard B. Hollis, Chairman
and Chief Executive Officer of Hollis-Eden."HE3286
represents a potential first-in-class treatment with a new class of hormones
to control glucose metabolism in type 2 diabetes. The role that hormones
play in metabolism is well documented in the scientific literature, and
HE3286 is an analog of a naturally occurring parent hormone believed to play
a fundamental role in regulating glucose metabolism. Given this biological
lineage, along with the preclinical data we have generated to date with
HE3286, we are optimistic about the compound's
potential as a novel therapy for the treatment of type 2 diabetes and
possibly other metabolic disorders. In addition, based on the role of
inflammation common to both metabolic and autoimmune disorders, we believe
that HE3286 offers potential therapeutic benefit in autoimmune conditions
such as rheumatoid arthritis given its demonstrated ability to
simultaneously regulate signaling pathways central to inflammation and
immune function. "Advancing HE3286 to this stage of development
further demonstrates the progress we are making with our next-generation
drug development program" added Hollis.
"In addition to our expectation of initiating
clinical development of HE3286 in metabolic disorders, we plan to file an
IND for HE3286 for autoimmune disorders later this year, as well as an IND
for our cancer drug candidate HE3235 in late 2007 or early 2008. At the same
time, we are profiling additional follow-on oral next-generation compounds
for a variety of diseases and disorders. Through these efforts, we are
translating our proprietary class of adrenal steroid hormones into potential
pharmaceutical products with competitive advantages in indications that have
well-defined clinical paths and large, well-established markets.
About Diabetes Diabetes, a disease characterized by high levels of glucose in the blood,
is reaching epidemic proportions in the U.S. and other developed countries.
Approximately 20 million Americans and over 160 million people worldwide
have type 2 diabetes. As a result of an aging population and a rise in
obesity rates, a common risk factor in this disease, the prevalence of type
2 diabetes is increasing rapidly. In diabetes, the body does not produce sufficient quantities of, or
properly use, insulin. Insulin is a hormone needed to carry glucose from the
blood into cells, where it is converted to energy necessary for proper
cellular function. When insulin is not available in sufficient quantities or
does not function properly, glucose levels in the blood become elevated,
leading to a variety of severe medical conditions. Included among the therapeutic approaches to type 2 diabetes are drugs
designed to increase insulin production by the pancreas, drugs to reduce
glucose production by the liver, and drugs to increase the body's
sensitivity to insulin, thereby improving glucose disposal by the
bloodstream. Of these, insulin sensitizers represent the largest class of
oral anti-diabetic agents, representing 48% of the annual sales in the $12
billion per year global oral anti-diabetic market. Currently approved
insulin sensitizers, known as glitazones, appear to act primarily through
the activation of the nuclear hormone receptor known as PPARgamma. While
these agents can lower blood glucose, they have been associated with
undesirable side effects such as weight gain and edema. Hollis-Eden Pharmaceuticals Hollis-Eden Pharmaceuticals, Inc. is a world leader in the development of
a proprietary class of adrenal steroid hormones as novel pharmaceuticals for
human health. Through its Hormonal Signaling Technology Platform,
Hollis-Eden is developing a new series of small molecule compounds that are
metabolites or synthetic analogs of endogenous hormones derived by the
adrenal glands from the body' most abundant
circulating steroid. These steroid hormones, designed to restore the
biological activity of cellular signaling pathways disrupted by disease and
aging, have been demonstrated in humans to possess several properties with
potential therapeutic benefit -- they regulate innate and adaptive immunity,
reduce nonproductive inflammation and stimulate cell proliferation. The
Company's clinical drug development candidates
include HE3286, a next-generation compound being prepared for clinical
trials in treating type 2 diabetes and potentially rheumatoid arthritis. A
second next-generation candidate, HE3235, has been selected for clinical
development in cancer. In addition to these clinical development candidates,
Hollis-Eden has an active research program that is generating additional new
clinical leads that are being further evaluated in preclinical models of a
number of different diseases. For more information on Hollis-Eden, visit the

http://www.immunesupport.com/library/showarticle.cfm/ID/4532 Question: Dr. Holtorf,
in a past article on the effective treatment of Chronic Fatigue Syndrome and
Fibromyalgia** you stated that “individuals with these syndromes have measurable
hypothalamic, pituitary, immune and coagulation dysfunction. These abnormalities
then result in a cascade of further abnormalities, in which stress plays a
role.” Could you discuss in detail how you approach testing for and treating
these problems in CFS and FM patients? Dr. Holtorf: There is a
mixture of underlying causes of Chronic Fatigue Syndrome (CFS) and Fibromyalgia
(FM), and each underlying abnormality can trigger further problems. This results
in a cascade of multiple physiologic abnormalities and a perpetuating vicious
cycle. Successful treatment requires that this vicious cycle be addressed on
multiple levels. This cascade of abnormalities [beginning with the "Genetic
Predisposition" and then "Triggering Event of Physiologic Stress"] is
graphically depicted below - and a few of the abnormalities are also discussed.
![]() [ click to enlarge ] Immune Dysfunction If a complete immune panel is done on CFS and FM patients, almost all have immune dysfunction, which often includes poor natural killer cell function and/or high RNAse-L activity. Natural killer cell function. These cells are very important in killing viruses and bacteria. It is very difficult to eradicate chronic infections when these cells are not functioning well. Antibiotics and antivirals do not work well and are often infective if the immune system is not stimulated as well. You are never able to kill all the infectious agents unless the body is able to clean up the residual left by the antibiotic or antiviral. There are a number of methods to do this. What we use depends on the infection present, but includes both natural and pharmaceutical antivirals, antibiotics, immune boosters and immune modulators. Growth hormone, thyroid and cortisol (adrenal hormone) are also very good immune enhancers. Yes, I said cortisol - low doses of cortisol for people who have adrenal insufficiency act as an immune enhancer. Large doses are immune suppressors. Your body normally increases cortisol in times of infection. Oxidative therapies, discussed below, can be very powerful. We customize the specific treatment for the patient. RNase-L activity: In response to infection, the body can produce an enzyme called RNase-L that breaks down the viral RNA to rid the body of the infection. When the infection is gone this enzyme is then turned off. In CFS, however, the presence of chronic infections can result in the stimulation of an abnormal “super” RNase-L enzyme that also breaks down the cell’s own RNA that is used to code for proteins and required for normal functioning. The result is poorly functioning cells and an increase in cellular apoptosis (programmed cell death). Treatment consists of eradication of the chronic infection and immune modulators. The RNase-L activity test can be done by Redlabs USA (http://www.RedlabsUSA.com ). (No affiliation). Coagulation Problems This is diagnosed with a specialized laboratory test that includes soluble fibrin monomer, prothrombin fragment 1 +2, fibrinogen and thrombin/antithrombin complex. Defects are typically treated with heparin and vascular enzymes such as lumbrokinase and serapeptidase to stop the excessive production of soluble fibrin monomers and to help clean up the fibrin already laid down. Eradication of chronic infections is also important, as there is often a chronic infection as the underlying stimulus of the abnormal activation of coagulation. Low Thyroid CFS and FM patients almost always have low tissue levels of thryoid hormones due to hypothalamic and pituitary dysfunction and thyroid resistance, which has been documented in a number of studies. Unfortunately, this hypothryiodism is missed 80% to 90% of the time because standard thyroid tests and TSH [thyroid-stimuating hormone] levels are usually normal, and this is what 90% of doctors are accustomed to using to diagnose low thyroid. Currently, the best method to diagnose low thyroid in these conditions is to look at the T3/reverseT3 ratio. [TSH causes the thyroid gland to produce two hormones: triiodothyronine (T3) and thyroxine (T4).] When CFS and FM patients are treated with thyroid, they are almost always under-dosed because their pituitary dysfunction results in their TSH becoming quickly suppressed, which normally indicates too much thyroid. Because these patients have pituitary dysfunction, one must not rely on the TSH, and not treat based on this parameter. In addition, due to the thyroid resistance, T4 preparations such as Synthroid and Levoxyl cannot provide adequate tissue levels of the active hormone. T4/T3 combinations such as Armour thyroid can be of benefit, but many patients also find that these preparations also do not provide adequate relief. Straight timed released T3 is often the best preparation to obtain adequate tissue levels. Adrenal Insufficiency Standard blood testing will almost always miss this deficiency. Studies show that with sophisticated testing, close to 100% of CFS and FM have adrenal dysfunction and treatment can be very beneficial. To diagnose, we typically use symptoms and a combination of blood sugar, free cortisol, and HgA1C%. Again, one must have a high clinical suspicion and not just think in terms of 'normal' and 'abnormal'. These normal levels are determined for healthy individuals, not the chronically ill, so the cortisol levels should be higher with this illness. 24-hour urine and saliva tests can be done, but these can also result in false positive and false negative results. Growth Hormone Deficiency Many CFS and FM patients are low in growth hormone. This hormone is produced in the pituitary, and with the documented pituitary dysfunction in CFS and FM, it is not unexpected that there is such a deficiency in these illnesses. Treatment can sometimes make a tremendous impact and because the cost has come down significantly in recent years, it is a viable treatment for more patients. IGF-1 is the best indication for growth hormone levels, but again, one cannot use the standard laboratory normal ranges to diagnose.
* * * * *
Question: Once you’ve determined which problems a CFS or FM patient has, do you prescribe both traditional and alternative treatments, or do you focus on a single method at a time? Dr. Holtorf: In order to treat these diseases adequately, one must simultaneously use both traditional and so-called alternative treatments. If one treatment were used at a time it would take many years before the patient feels better. Many treatments can be withdrawn as the patient improves.
* * * * *
Question: Please tell us a little bit about the Holtorf Medical Group, Inc: The Center for Hormone Imbalance, Hypothyroidism and Fatigue (http://www.HoltorfMed.com) where you practice. Dr. Holtorf: I started the Holtorf Medical Group to concentrate on the treatment of complex endocrine dysfunction, hypothyroidism, fatigue, CFS and fibromyalgia. Eighty percent of our practice is for patients complaining of fatigue, with CFS and FM probably being the biggest part of the practice.
* * * * *
Question: What are the biggest challenges you face with treating CFS and FM patients? Dr. Holtorf: Although we have good success with CFS and FM, these are challenging cases that require doctors to spend significant time with the patient. It cannot be accomplished with seven-minute office visits.
* * * * *
Question: What are the biggest successes you’ve experienced in treating CFS and FM? Dr. Holtorf: Many of these patients are very sick and have given up. It is so gratifying to get these patients back to having a life. They are just so grateful. Many have been unable to work and/or have been on disability and now, following treatment, are happy, functional and productive.
* * * * *
Question: Are you working on any promising new treatments at this time – either through research or through a trial and error process with your patients? Dr. Holtorf: We are continually working on and implementing new treatments every day in practice. We have been using and refining many of the so-called “new” treatments for many years. For instance, Valcyte is considered a new, novel treatment for CFS, but we have been using it for 4 years, since it was first approved.
* * * * *
Question: What are the most exciting developments you’ve seen recently in treatment options for CFS and FM? Dr. Holtorf: Recent developments are taking place in a stepwise manner, but I do not believe it will be through the so-called ‘mainstream’ medicine one-drug cures. I think these are very treatable conditions, and advances will only continue to improve treatment. I do believe, however, that the incidences of CFS and FM will significantly increase and at some point will be considered an epidemic because they are very poorly treated through the standard healthcare delivery system. ____ Note: This information has not been evaluated by the FDA.
