The important news:

  • Oncology Pipeline | Pasireotide (SOM230) - A Multigland Somatostatin Analogue | Novartis Oncology
  • Letrozole, a new oral non-steroidal aromastase inhibitor in treating postmenopausal patients with advanced breast cancer. A pilot study - .oxfordjournals.org - "There was a statistically significant decrease in plasma cortisol, which appeared clinically irrelevant since all values remained within the normal range"
  • Mortality and Morbidity in Cushing's Syndrome in New Zealand - Clin Endocrinol (Oxf). 2011 May 24 - "36 patients died during follow-up compared with 8.8 expected deaths (SMR 4.1, 95%CI 2.9-5.6) ... CS is associated with both high mortality and a high prevalence of co-morbidities, even when biochemical cure rates are between 80-90"
  • Older age memory loss tied to stress hormone receptor in brain - Science Daily, 4/6/11 - "one receptor was activated by low levels of cortisol, which helped memory. However, once levels of this stress hormone were too high they spilled over onto a second receptor. This activates brain processes that contribute to memory impairment ... high levels of the stress hormone in aged mice made them less able to remember how to navigate a maze. The memory recall problem was reversed when the receptor linked to poor memory was blocked ... lowering the levels of these stress hormones will prevent them from activating a receptor in the brain that is bad for memory ... The researchers are currently investigating a new chemical compound which blocks an enzyme -- 11beta-HSD1 -- that is involved in producing stress hormones within cells"
  • High blood cortisol levels significantly increases death rate in patients with acute coronary syndrome - Science Daily, 5/27/10 - "1036 patients with acute coronary syndrome were studied for an average period of 7.7 years. There were no significant differences in the serum cortisol levels between patients with and without acute coronary syndrome. However, the patients with ACS and high cortisol levels had a significantly elevated number of deaths when compared to the patients with ACS and the lowest cortisol levels. 758 total deaths were reported during the follow-up period. The ACS patients with the highest cortisol levels (i.e. the highest 25% serum cortisol) were significantly more likely to die from fatal cardiovascular events than those with the lowest cortisol levels (the lowest 25% serum cortisol). (The hazard ratio for highest versus lowest quartile of SCC was 1.89"
  • The relationship of serum and salivary cortisol levels to male sexual dysfunction as measured by the International Index of Erectile Function - Int J Impot Res. 2009 May 7 - "testosterone (T) and cortisol (F) ... (Total-T, Free-T, Bioavailable-T, Total-F and Bioavailable-F) and salivary hormones (Saliva-T and Saliva-F) ... International Index of Erectile Function (IIEF) ... Free-T and Bioavailable-T showed significant inverse correlations with age (P<0.01). In the group not taking antidepressants, the levels of Bioavailable-F and Saliva-F showed significant inverse correlations with a portion of the IIEF score (P<0.05). However, reductions in Bioavailable-T and Saliva-T showed no association with the IIEF score. In the group taking antidepressants, these hormone levels showed no correlation with IIEF"
  • Effects of phosphatidylserine supplementation on exercising humans - Sports Med. 2006;36(8):657-69 - "S-PtdSer 800 mg/day reduced the cortisol response to overtraining during weight training while improving feeling of well-being and decreasing perceived muscle soreness"
  • Associations of salivary cortisol with cognitive function in the Baltimore memory study - Arch Gen Psychiatry. 2007 Jul;64(7):810-8 - "Higher levels of pretest and mean cortisol as well as the area under the curve of cortisol over the study visit were associated with worse performance (P < .05) in 6 domains (language, processing speed, eye-hand coordination, executive functioning, verbal memory and learning, and visual memory). For instance, an interquartile range increase in the area under the curve was equivalent to a decrease in the language score expected from an increase in 5.6 (95% confidence interval, 4.2-7.1) years of age"
  • Chronic Exposure To Stress Hormone Causes Anxious Behavior In Mice - Science Daily, 4/17/06 - "Scientists already knew that many people with depression have high levels of cortisol, a human stress hormone, but it wasn't clear whether that was a cause or effect. Now it appears likely that long-term exposure to cortisol actually contributes to the symptoms of depression"
  • Pharmacologic management of Cushing syndrome : new targets for therapy - Treat Endocrinol. 2005;4(2):87-94 - "Compounds with neuromodulatory properties have been effective in only a limited number of cases of hypothalamic-pituitary-dependent Cushing disease, the most common form of Cushing syndrome. These agents include serotonin antagonists (cyproheptadine, ketanserin, ritanserin), dopamine agonists (bromocriptine, cabergoline), GABA agonists (valproic acid [sodium valproate]), and somatostatin analogs (octreotide). Interesting new avenues at the pituitary level involve the potential use of thiazolidinedione compounds, such as rosiglitazone, and of retinoic acid, which are ligands of different nuclear hormone receptors involved in hypothalamic-pituitary regulation"
  • Diabetes Drugs May Help Cushing's Syndrome - Reuters Wire, 11/07/2002 - "Cushing's syndrome results from high levels of the hormone cortisol, and can cause fat accumulation in the upper body and face, and thinning of the arms and legs. Patients can experience high blood pressure and high blood sugar, along with depression, fatigue, irritability and weakened bones ... a protein called PPAR-gamma, which is found on pituitary gland tumor cells, appears to be linked to overproduction of ACTH ... researchers injected mice with ACTH-secreting pituitary tumor cells and then treated them with commonly used diabetes drugs, rosiglitazone (Avandia) and troglitazone, or an inactive placebo ... There was an 85% reduction in ACTH and a corresponding 96% reduction in their cortisol-like hormone"
  • Mirtazapine Regulates Stress Hormones, Improves Sleep In Depressed Patients - Doctor's Guide, 8/8/01 - "Mirtazipine might be the best option for depressed patients with sleep disturbance and irregularities in stress hormone function ... Depression is often accompanied by sleep disturbance -- subjective and objective -- as well as [hypothalamic-pituitary-adrenal] HPA-axis dysregulation ... Mirtazapine is a treatment that [profoundly affects] the HPA-axis within hours and promotes sleep within days ... They tested the 24-hour urinary free cortisol (UFC) levels of 16 healthy men and 20 men and women with major depression ... mirtazipne significantly reduced UFC concentrations, which is often elevated in depressed patients"
  • Cortisol - Keeping a Dangerous Hormone in Check - Life Extension Magazine, 7/04 - "daily cortisol production increased by 54% from a group of 21- to 30-year-old men to a group of men over 70 ... Phosphatidylserine, DHEA, and ginkgo biloba all have been shown to reduce the amount of cortisol produced during stressful events, and these stress fighters can help retard the negative consequences of this hormone" - See iHerb phosphatidylserine products.
  • The Role of Cortisol and Depression: Exploring New Opportunities for Treatments - Psychiatric Times, 5/04 - "Although glucocorticoid production is essential for survival, overproduction is associated with a significant disruption of cellular functioning, which, in turn, leads to widespread physiological dysfunction ... Cortisol, a glucocorticoid released from the adrenal cortex, is the end product of the HPA axis ... The physiological function of DHEA and its sulphated metabolite (DHEA-S) is unclear, but these circulating corticosteroids have been shown to possess antiglucocorticoid properties, and high cortisol/DHEA ratios are reported to be associated with persistent depression"
  • Why Are So Many Women Depressed? - Scientific America Women's Health: A Life Long Guide, Summer 1998 (see the subtopic "Stress and Cortisol") - "It is unclear whether depression is a cause or a consequence of elevated cortisol levels, but the two are undoubtedly related."
  • Wilson's Reverse T3 Dominance Syndrome - knoxintegrativemed.com - "However, when a person experiences prolonged stress, the adrenal glands respond by manufacturing a large amount of cortisol. Cortisol inhibits the conversion of T4 to T3 and favors the conversion of T4 to RT3. If stress is prolonged, a condition called Reverse T3 Dominance occurs and persists even after the stress passes and cortisol levels fall. Apparently, RT3 itself acts like cortisol and blocks the conversion of T4 to T3"
  • Wilson's Syndrome - providentmedical.com - "We know that elevated amounts of cortisol, the major stress hormone, can block 5 prime deiodinase, keeping T4 from being converted to T3.  This results in most of the T4 being converted into reverse T3, which then needs the available 5 prime deiodinase to be converted into T2."

  • Fish oil prevents the adrenal activation elicited by mental stress in healthy men - Diabetes Metab. 2003 Jun;29(3):289-295 - "In control conditions, mental stress significantly increased heart rate, mean blood pressure, and energy expenditure. It increased plasma epinephrine from 60.9 +/- 6.2 to 89.3 +/- 16.1 pg/ml (p<0.05), plasma cortisol from 291 +/- 32 to 372 +/- 37 micromol/l ... After 3 weeks of a diet supplemented with n-3 fatty acids, the stimulation by mental stress of plasma epinephrine, cortisol, energy expenditure, and plasma non esterified fatty acids concentrations, were all significantly blunted ... Supplementation with n-3 fatty acids inhibits the adrenal activation elicited by a mental stress" - See Mega Twin EPA at Amazon.com.
  • Disappointing Data Confound Claims For DHEA Effectiveness [against Alzheimer's] - Psychiatric News, 6/6/03 - "DHEA has been reported to reduce cortisol, the so-called "stress hormone," which in response to stress is released in large quantities that have been linked to neuronal stress and damage" -  Does anyone detect bias in that title?  I don't know if DHEA helps Alzheimer's or not but I feel the title should have been something like "Alzheimer's Shows Trend Toward Improvement with DHEA at 3 Months".  Their attitude seems to be that nothing works except what we write prescriptions for.  The way I understand it, Alzheimer's usually gets worse, not better and cholinesterase inhibitors slow the disease, they don't reverse it and three months is a short time to determine if it is working.  For example, see the following  in the same issue of Clinical Psychiatry News.  See iHerb DHEA products. - Ben

  • Stress, Cortisol and Health - Supplement Watch Newsletter, 10/02 - "several lines of evidence have converged to solidify the concept that stress makes us fat (because of cortisol), thins our bones (because of cortisol), shrinks our brains (because of cortisol), suppresses our immune system (because of cortisol), saps our energy levels (because of cortisol), and kills our sex drive (because of cortisol) ... Take a daily multivitamin/multi-mineral supplement - because calcium, magnesium, vitamin C and B-complex vitamins are needed for a proper stress response ... Chief among the supplements with documented cortisol-controlling effects are Phosphatidylserine, Beta-sitosterol, Magnolia bark, Theanine, Epimedium, Ashwagandha and Passionflower"
  • Phosphatidylserine (PS) The Essential Brain Nutrient - Life Extension Magazine, 9/02 - "Among its list of functions, phosphatidylserine stimulates the release of dopamine (a mood regulator that also control physical sensations, and movement), increases the production of acetylcholine (necessary for learning and memory), enhances brain glucose metabolism (the fuel used for brain activity), reduces cortisol levels (a stress hormone), and boosts the activity of nerve growth factor (NGF), which oversees the health of cholinergic neurons"

  • Physical and Psychological Effects of Stress - MedicineNet.com, 2/02 - "Under excessive stress, we tend to produce cortisol, the classic anti-stress hormone produced by our body, perhaps to conserve energy. However the side-effect here is sexual dysfunction and infertility as cortisol also inhibits production of the hormones essential for sexual"
  • Errant Enzyme Causes Big Bellies - WebMD, 12/11/01 - "They looked at an enzyme called 11-beta hydroxysteroid dehydrogenase type 1. This enzyme is able to increase the level of cortisol in fat cells without raising the level of cortisol in the blood"
  • Single enzyme to blame for potbellies: study - MSNBC, 12/6/01 - "What they found was that a single enzyme in fat cells that raises levels of cortisol — the “fight or flight” stress hormone — triggers fat accumulation around the belly and its associated ill effects ... The researchers were drawn to the role of cortisol because patients with a rare illness known as Cushing syndrome — who have too much of the steroid hormone in their blood — develop severe obesity concentrated around their middles and become diabetic ... Since overweight people without Cushing syndrome typically don’t have too much cortisol in their bloodstreams, Flier hypothesized that they may be producing high cortisol levels solely in their fat cells — possibly because the enzyme HSD-1, which makes cortisol from an inactive molecule, is overactive ... The level of cortisol in their stomach fat tissue was 15 percent to 30 percent higher than in their non-engineered counterparts" - Note: The way I read this article, the final culprit is still the cortisol and there are ways to reduce cortisol now.
  • Retinoic acid prevents experimental Cushing syndrome - J Clin Invest, October 2001, Volume 108, Number 8, 1123-1131 - "This glucocorticoid excess produces abnormal fat deposition, adrenal hyperplasia, thinning of the skin, hypertension, and psychological disturbances"

  • How You React to Stress May Affect How Your Clothes Fit - WebMD, 1/16/01 - "fat created by cortisol is the "deep-belly" kind, which, one expert says, is known to increase health risks"
  • RU-486 could aid variety of ills - MSNBC, 11/2/00 - "RU-486's ability to block the action of a different hormone cortisol has prompted doctors to try it for psychotic depression. In addition to feeling sad and worthless, people with this devastating condition have distorted thinking and often suffer delusions or hallucinations. Many
    become suicidal.

    They have very, very disturbing and crazy thoughts ... and they have no ability to suppress them, said Joseph K. Belanoff, a California psychiatrist who is chief executive officer of Corcept Therapeutics Inc., a small pharmaceutical company. Corcept is sponsoring a study of RU-486 for psychotic depression.

    Several lines of evidence have led researchers to suspect that some of the symptoms of psychotic depression are caused by an excess of cortisol in the brain. Cortisol levels rise in response to stress and may be abnormally elevated in depressed individuals. Similar symptoms can occur in patients with Cushing's syndrome, an overabundance of cortisol usually caused by a tumor, and RU-486 has cured the mental disturbance in some
    such cases.

    Our feeling has been that a lot of the cognitive problems and delusions that you see in some of the patients are due to the [cortisol], said Alan F. Schatzberg, chairman of the psychiatry department at Stanford University School of Medicine, where researchers are conducting a study that will test RU-486 on 30 patients with psychotic depression.

    RU-486 or other cortisol-blocking drugs may be better alternatives than ... some of the typical treatments such as antipsychotic drugs or electric shock therapy, he said."
  • Neuroscience finds foggy link between depression and memory loss - CNN, 4/18/00 - "Studies show that prolonged depression or stress leads to elevated levels of cortisol, a "stress" hormone produced by the adrenal glands. This in turn appears to shrink or atrophy the hippocampus, the sea-horse shaped part of the brain associated with many kinds of memory and learning."
  • STGI Announces Anticort's FDA Phase I/II is Moving Forward - aegis.com, 7/28/99 - "Procaine (the active ingredient of Anticort(TM)) has been used clinically for more than 40 years, primarily as the local injectable anesthetic Novocaine. Despite the widespread use of procaine, reports of side effects have been rare, and are usually associated with excessive dosage, rapid absorption or inadvertent intravascular injection ... For the pharmacokinetics study, participants will receive Anticort(TM) at a single oral dose of 200 mg (cohort A), 400 mg (cohort B), 600 mg (cohort C) or 800 mg (cohort D). For the 8-week continuous dosing study, participants will receive 200 mg (1 pill per day; cohort A), 400 mg (1 pill twice daily; cohort B), 600 mg (1 pill three times daily; cohort C) or 800 mg (2 pills twice daily; cohort D). To ensure the safety of each dose level, these cohorts will be enrolled sequentially"
  • Study Supports Role Of Anticort In Treating Alzheimer's, HIV - Doctor's Guide, 4/17/98 - "Cortisol's role as a cause of disease is most recently confirmed in a study to be published in the May issue of the journal Nature Neuroscience. Authored by Dr. Sonia Lupien of McGill University, the study reports that high levels of cortisol play a key role in Alzheimer's, memory loss, shrinkage of the brain and aging. Dr. Lupien also states that such illnesses might be prevented with medications to reduce elevated cortisol levels."
  • Georgetown Researchers Report Development of New Way to Control Excess Cortisol Levels - Georgetown University Medical Center, 6/12/00 - "Although more work is needed to understand how Anticort works, these results clearly indicate that we now have a powerful tool to control the stress response and its detrimental effects on the body"
  • Endocrinology of Aging - Medscape, 3/00 - "Excessive lifelong adrenal cortisol feedback on the brain may exacerbate the aging-associated loss in neuronal synapses and plasticity"
  • Hypericum, Drug Interatcions, and Liver Effects  - MedHerb.com, 2/00 - "Endogenous hormones metabolized by the CYP3A enzyme system - estradiol, estriol, testosterone, cortisol"
  • The Neurobiology of Depression - Scientific America, 6/98 - "When a threat to physical or psychological well-being is detected, the hypothalamus amplifies production of corticotropin-releasing factor (CRF), which induces the pituitary to secrete ACTH. ACTH then instructs the adrenal gland atop each kidney to release cortisol"
  • Acetyl-L-carnitine in Alzheimer disease: a short-term study on CSF neurotransmitters and neuropeptides - Alzheimer Dis Assoc Disord 1995 Fall;9(3):128-31 - "beta-endorphins significantly decreased after treatment; plasma cortisol levels matched this reduction. Since both CSF beta-endorphins and plasma cortisol decreased, one possible explanation is that ALCAR reduced the AD-dependent hypothalamic-pituitary-adrenocortical (HPA) axis hyperactivity"
  • Psychotic Depression - healthyplace.com - "Researchers aren't exactly sure what causes major depressive disorder with psychotic features (psychotic depression), but it's frequently associated with high levels in the blood of a hormone called cortisol"
  • Gerovital GH-3 information - International Antiaging Systems - "It is also known that Gerovital-H3 can help reduce cortisol levels, the hormone responsible for stress and a rare hormone in that it is one of the few that increases with age. It is believed that high-cortisol levels lead to accelerated aging because cortisol “attacks” the hypothalamus, the area of the brain that “controls” the endocrine system. Ironically cortisol may run out-of-control due to its ability to damage the hypothalamus that controls the adrenal glands that produce cortisol!" - Note:  I'm not a doctor but the way I understand it, GH-3 (procaine HCl) reduces 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA) activity.  This is what statins do to lower cholesterol.  Cortisol is made from cholesterol therefore less cholesterol equals less cortisol.  The company making Anticort (procaine HCl), stopped after phase II studies.  See J Pharmacol Exp Ther. 2003 Dec;307(3):1148-57.

Alternative News:

  • Oxytocin promotes social behavior in infant rhesus monkeys - Science Daily, 4/28/14 - " In another test, the researchers found that after exposure to oxytocin, monkeys had lower levels of cortisol in their saliva. Cortisol is produced by the adrenal glands in response to stress. Lower cortisol levels after oxytocin exposure indicate that oxytocin may also function to diminish anxiety" - See Oxy Pro (Oxytocin) Nasal Spray at International Anti-aging Systems.
  • Resveratrol reverses the effects of chronic unpredictable mild stress on behavior, serum corticosterone levels and BDNF expression in rats - Behav Brain Res. 2014 Feb 3 - "Depression is one of the most common neuropsychiatric disorders and has been associated with the neuroendocrine system and alterations in specific brain proteins ... The present study attempts to explore the mechanisms underlying the antidepressant-like action of resveratrol by measuring serum corticosterone levels and the content of brain derived neurotrophic factor (BDNF) in the hippocampus and amygdala of rats exposed to the chronic unpredictable mild stress (CUMS). Male Wistar rats were subjected to the CUMS protocol for a period of 5 weeks to induce depressive-like behavior. Resveratrol treatment (20, 40 and 80mg/kg/i.p. 5 weeks) significantly reversed the CUMS-induced behavioral abnormalities (reduced sucrose preference, increased immobility time and decreased locomotor activity) and the elevated serum corticosterone levels observed in stressed rats. Additionally, five-weeks of CUMS exposure significantly decreased BDNF levels in the hippocampus and amygdala, and was accompanied by decreased phosphorylation of extracellular signal-regulated kinase (pERK) and cAMP response element-binding protein (pCREB), while resveratrol treatment normalized these levels. All of these effects of resveratrol were essentially identical to that observed with the established antidepressant, desipramine" - Note: "decreased ... the elevated serum corticosterone levels".  That might mean it lowers cortisol.  See resveratrol products at Amazon.com.
  • Probiotics a Potential Treatment for Mental Illness - Medscape, 11/19/13 - "although human studies are still largely lacking, they did find some with promising results on behavior, including 1 showing that healthy volunteers who received Lactobacillus helveticus R0052 plus B longum for 30 days reported significantly lower stress levels than those who received placebo, as well as significantly reduced urinary free cortisol levels ... Another study of 124 volunteers (mean age, 61.8 years) showed that those who consumed probiotic-containing yogurt for 3 weeks had significantly improved mood compared with those who received placebo ... the term "psychobiotic" was created as recent studies have begun to explore a possible link between probiotics and behavior ... As a class of probiotic, these bacteria are capable of producing and delivering neuroactive substances such as gamma-aminobutyric acid [GABA] and serotonin, which act on the brain-gut axis ... a study of human patients with chronic fatigue syndrome showed that those who consumed an active strain of L casei 3 times a day had significantly higher improvement scores on anxiety measures than did those who received matching placebo" - See probiotic products at Amazon.com.
  • Effects of Soy, Whey Protein Supplementation Post-Exercise - Science Daily, 10/12/13 - "Our main findings demonstrate that 14 days of supplementation with soy protein does appear to partially blunt serum testosterone. In addition, whey influences the response of cortisol following an acute bout of resistance exercise by blunting its increase during recovery"
  • Effect of Magnolia officinalis and Phellodendron amurense (Relora(R)) on cortisol and psychological mood state in moderately stressed subjects - J Int Soc Sports Nutr. 2013 Aug 7;10(1):37 - "Magnolia (Magnolia officinalis) and Phellodendron (Phellodendron amurense) barks are medicinal plants commonly used as traditional remedies for reducing stress and anxiety ... assessed salivary cortisol exposure and psychological mood state in 56 subjects (35 men and 21 women) screened for moderate stress and supplemented with a standardized/patented MP combination (Relora(R), Next Pharmaceuticals) or Placebo for 4 weeks ... After 4 weeks of supplementation, salivary cortisol exposure was significantly (p<0.05) lower (-18%) in the Relora group compared to Placebo. Compared to Placebo, the Relora group had significantly better (p<0.05) mood state parameters, including lower indices of Overall Stress (-11%), Tension (-13%), Depression (-20%), Anger (-42%), Fatigue (-31%), and Confusion (-27%), and higher indices of Global Mood State (+11%) and Vigor (+18%)" - Note: The biggest affect was on anger (-42%).  See Relora at Amazon.com.
  • Fish oil supplementation reduces cortisol basal levels and perceived stress: A randomized, placebo-controlled trial in abstinent alcoholics - Mol Nutr Food Res. 2013 Feb 6 - "Behavioral distress and dysfunctions of hypothalamic-pituitary-adrenocortical (HPA) axis play a central role in alcohol abuse. Omega-3 fatty acids are proposed as having antistress, regulatory effects on HPA responsiveness ... doubleblind, placebo-controlled trial was performed in male alcoholics undergoing residential rehabilitation program, to evaluate the effects of 3-week supplementation with fish-oil providing eicosapentaenoic (60 mg/day) and docosahexaenoic acid (252 mg/day) on perceived stress/anxiety and HPA activity, assessed by measuring saliva basal cortisol levels at various daytimes ... In conclusion, an elevated omega-3 intake may reduce distress symptoms and basal cortisol secretion in abstinent alcoholics, thus providing a valid subsidiary measure to increase the efficacy of rehabilitation programs in ethanol addicts" - Note:  I'm wondering why they chose such a low dose.  That's not even the amount of omega-3 in the average capsule on one good fish oil capsule.  See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Oxytocin, Social Sharing and Recovery from Trauma - Science Daily, 12/18/12 - "'social sharing of emotions' (SSE) ... SSE, like the neuropeptide oxytocin (OT) -- known variously as 'the hug hormone', 'the moral molecule' and 'the natural love drug' -- has a calming and bonding function in humans. So a team of researchers decided to examine whether it followed that administering oxytocin might ease this therapeutic and powerful 'social sharing of emotions' ... What they found was that OT did not make people more talkative -- the word counts in the letters were the same -- but it did increase the participants' willingness to share the specific component that is responsible for the therapeutic effects of social sharing: emotions. As the researchers note, "the findings are the more remarkable because they were obtained among men, who may be less inclined than women to express their emotions." ... there may be further implications for human health, related to OT's antagonistic effect on the stress hormone cortisol" - See Oxytocin Factor or Oxy Pro (Oxytocin) Nasal Spray at International Anti-aging Systems.
  • Nutrient in eggs and meat may influence gene expression from infancy to adulthood - Science Daily, 9/20/12 - "Consuming greater amounts of choline -- a nutrient found in eggs and meat -- during pregnancy may lower an infant's vulnerability to stress-related illnesses, such as mental health disturbances, and chronic conditions, like hypertension, later in life ... More choline in the mother's diet led to a more stable HPA axis and consequently less cortisol in the fetus ... Pressman joined a team led by Marie Caudill, Ph.D., R.D., professor in the Division of Nutritional Sciences at Cornell, in studying 26 pregnant women in their third trimester who were assigned to take 480 mg of choline per day, an amount slightly above the standard recommendation of 450 mg per day, or about double that amount, 930 mg per day. The choline was derived from the diet and from supplements and was consumed up until delivery" - See citicholine at Amazon.com.

  • Resveratrol prevents dexamethasone-induced expression of the muscle atrophy-related ubiquitin ligases atrogin-1 and MuRF1 in cultured myotubes through a SIRT1-dependent mechanism - Biochem Biophys Res Commun. 2011 Dec 7 - "Results suggest that resveratrol can prevent glucocorticoid-induced muscle wasting and that this effect is at least in part SIRT1-dependent" - Note:  I think what they are saying is that resveratrol may help prevent muscle loss due to high cortisol.  Stress increases cortisol.  Exercise may be partially defeating as far as muscle tone in that it increases cortisol.  That's just my theory.  See resveratrol products at Amazon.com.
  • Omega-3 supplements show benefits against anxiety: Human data - Nutra USA, 9/14/11 - "the Ohio State researchers recruited 68 medical students to participate in their parallel group, placebo-controlled, double-blind trial. The med students were given either placebo capsules or omega-3 capsules containing 2085 mg of EPA (eicosapentaenoic acid) and 348 mg DHA (docosahexanoic acid) ... Results showed a 14% reduction in levels of the production of pro-inflammatory interleukin 6 (IL-6), as well as a 20% reduction in anxiety symptoms in the omega-3 group, compared to the placebo group ... Proinflammatory cytokines promote secretion of corticotropin-releasing hormone (CRH), a primary gateway to hormonal stress responses; CRH also stimulates the amygdala, a key brain region for fear and anxiety. Accordingly, alterations in inflammation could also influence anxiety" - [Abstract] - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.  Note:  CRH increases cortisol.  See:
  • Grapefruit juice and liquorice increase cortisol availability in patients with Addison's disease - Eur J Endocrinol. 2011 Sep 6 - "Compared to the ordinary treatment, the median AUC for serum cortisol increased with liquorice (53783 vs. 50882, p<0.05) and GFJ (60661 vs. 50882, p<0.05). Cortisol levels in serum were also elevated 2.6h after tablet ingestion (liquorice 223 vs. 186 nmol/L, p<0.05; GFJ 337 vs. 186 nmol/L, p<0.01). Liquorice increased the median urinary cortisol/cortisone-ratio (0.43 vs 0.21, p<0.00001), whereas GFJ increased the (aTHF+THF)/THE-ratio (0.55 vs 0.43, p<0.05)" - Note:  From my readings, most have too much cortisol already.  I've read where licorice increases it.  Licorice and grapefruit juice sounds like an unlikely combination but people might want to be aware of it.
  • Preventive Action of Panax ginseng Roots in Hypercortisolism-induced Impairment of Hippocampal Neurons in Male C57BL/6N Mice - Phytother Res. 2011 Aug;25(8):1242-5 - "An increasing number of people suffering from hypercortisolism are at risk of developing hippocampus impairment and mental disorders. The aim of this study was to investigate whether the water extract of Panax ginseng roots (GWE) could prevent hypercortisolism-induced adverse consequences. Hypercortisolism was experimentally induced by repeated corticosterone injection in male mice. Treatment with corticosterone alone resulted in a significant decrease in hippocampus neurofilament light chain (NF-L) protein expression and induced depression-like behavior. Serum corticosterone was significantly increased in the corticosterone-treated mice. Treatment with GWE (800 and 400 mg/kg) during corticosterone treatment reduced or partially antagonized the effects induced by corticosterone toward the normal values of the controls; however, it failed to normalize increased corticosterone levels in corticosterone-treated mice. Overall, ginseng conclusively exhibited a protective action against hypercortisolism-induced impairment of hippocampal neurons" - See ginseng at Amazon.com.
  • Vitamin A Decreases Pre-receptor Amplification of Glucocorticoids in Obesity: Study on the Effect of Vitamin A on 11beta-Hydroxysteroid Dehydrogenase Type 1 Activity in Liver and Visceral Fat of WNIN/Ob Obese Rats - Nutr J. 2011 Jun 23;10(1):70 - "11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) catalyzes the conversion of inactive glucocorticoids to active glucocorticoids and its inhibition ameliorates obesity and metabolic syndrome. So far, no studies have reported the effect of dietary vitamin A on 11beta-HSD1 activity in visceral fat and liver under normal and obese conditions. Here, we studied the effect of chronic feeding of vitamin A-enriched diet (129mg/kg diet) on 11beta-HSD1 activity in liver and visceral fat of WNIN/Ob lean and obese rats ... Control groups received stock diet containing 2.6mg vitamin A/kg diet, where as experimental groups received diet containing 129mg vitamin A/Kg diet for 20 weeks ... Vitamin A supplementation significantly decreased body weight, visceral fat mass and 11beta-HSD1 activity in visceral fat of WNIN/Ob obese rats. Hepatic 11beta-HSD1 activity and gene expression were significantly reduced by vitamin A supplementation in both the phenotypes. CCAAT/enhancer binding protein alpha(C/EBPalpha), the main transcription factor essential for the expression of 11beta-HSD1, decreased in liver by vitamin A fed-obese rats, but not in lean rats. Liver X receptor alpha (LXR alpha), a nuclear transcription factor which is known to downregulate 11beta-HSD1 gene expression was significantly increased by vitamin A supplementation in both the phenotypes" - Note:  See my 11beta-HSD1 page.  11beta-HSD1 goes hand in hand with cortisol.

  • Assessment of psychotropic-like properties of a probiotic formulation ( Lactobacillus helveticus R0052 and Bifidobacterium longum R0175) in rats and human subjects - Br J Nutr. 2010 Oct 26:1-9 - "In the preclinical study, rats were daily administered PF for 2 weeks and subsequently tested in the conditioned defensive burying test, a screening model for anti-anxiety agents. In the clinical trial, volunteers participated in a double-blind, placebo-controlled, randomised parallel group study with PF administered for 30 d and assessed with the Hopkins Symptom Checklist (HSCL-90), the Hospital Anxiety and Depression Scale (HADS), the Perceived Stress Scale, the Coping Checklist (CCL) and 24 h urinary free cortisol (UFC). Daily subchronic administration of PF significantly reduced anxiety-like behaviour in rats (P < 0.05) and alleviated psychological distress in volunteers, as measured particularly by the HSCL-90 scale (global severity index, P < 0.05; somatisation, P < 0.05; depression, P < 0.05; and anger-hostility, P < 0.05), the HADS (HADS global score, P < 0.05; and HADS-anxiety, P < 0.06), and by the CCL (problem solving, P < 0.05) and the UFC level (P < 0.05). L. helveticus R0052 and B. longum R0175 taken in combination display anxiolytic-like activity in rats and beneficial psychological effects in healthy human volunteers" - Note, in case you missed it, it's saying that it also reduced cortisol.

  • Dietary fatty acid composition alters 11beta-hydroxysteroid dehydrogenase type 1 gene expression in rat retroperitoneal white adipose tissue - Lipids Health Dis. 2010 Oct 8;9(1):111 - "The enzyme 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) amplifies intracellular glucocorticoid action by converting inactive glucocorticoids to their active forms in vivo. Adipose-specific overexpression of 11beta-HSD1 induces metabolic syndrome in mice, whereas 11beta-HSD1 null mice are resistant to it. Dietary trans and saturated fatty acids (TFAs and SFAs) are involved in the development of metabolic syndrome, whereas polyunsaturated fatty acids (PUFA) offer protection against this. Here, we report the effects of chronic feeding of different diets containing vanaspati (TFA rich), palm oil (SFA rich) and sunflower oil (PUFA rich) at 10%level on 11beta-HSD1 gene expression in rat retroperitoneal adipose tissue. 11beta-HSD1 gene expression was significantly higher in TFA rich diet-fed rats compared to SFA rich diet-fed rats, which in turn was significantly higher than PUFA rich diet-fed rats. Similar trend was observed in the expression of CCAAT-enhancer binding protein-alpha (C/EBP-alpha), the main transcription factor required for the expression of 11beta-HSD1. We propose that TFAs and SFAs increase local amplification of glucocorticoid action in adipose tissue by upregulating 11beta-HSD1 by altering C/EBP--gene expression. The increased levels of glucocorticoids in adipose tissue may lead to development of obesity and insulin resistance, thereby increasing the risk of developing metabolic syndrome" - Note:  11beta-HSD1 goes hand in hand with cortisol.
  • Emodin, a natural product, selectively inhibits 11beta-hydroxysteroid dehydrogenase type 1 and ameliorates metabolic disorder in diet-induced obese mice - Br J Pharmacol. 2010 Sep;161(1):113-26 - "11beta-Hydroxysteroid dehydrogenase type 1 (11beta-HSD1) is an attractive therapeutic target of type 2 diabetes and metabolic syndrome. Emodin, a natural product and active ingredient of various Chinese herbs, has been demonstrated to possess multiple biological activities ... Emodin is a potent and selective 11beta-HSD1 inhibitor with the IC(50) of 186 and 86 nM for human and mouse 11beta-HSD1, respectively. Single oral administration of emodin inhibited 11beta-HSD1 activity of liver and fat significantly in mice. Emodin reversed prednisone-induced insulin resistance in mice, whereas it did not affect dexamethasone-induced insulin resistance, which confirmed its inhibitory effect on 11beta-HSD1 in vivo. In DIO mice, oral administration of emodin improved insulin sensitivity and lipid metabolism, and lowered blood glucose and hepatic PEPCK, and glucose-6-phosphatase mRNA. CONCLUSIONS AND IMPLICATIONS This study demonstrated a new role for emodin as a potent and selective inhibitor of 11beta-HSD1 and its beneficial effects on metabolic disorders in DIO mice. This highlights the potential value of analogues of emodin as a new class of compounds for the treatment of metabolic syndrome or type 2 diabetes" - Note:  (11beta-HSD1) goes hand in hand with cortisol.  It seems like what came first, the chicken or the egg.  I googled emodin and didn't see any reliable places that sold it.  One article said that it was in some resveratrol products and that the emodin was what caused the stomach problems.

  • Exercise Can Slow Onset of Alzheimer's Memory Loss: Scientists Identify Link - Science Daily, 1/25/13 - "the stress hormone CRF -- or corticotrophin-releasing factor -- may have a protective effect on the brain from the memory changes brought on by Alzheimer's disease ... CRF is most associated with producing stress and is found in high levels in people experiencing some forms of anxiety and depressive diseases. Normal levels of CRF, however, are beneficial to the brain, keeping the mental faculties sharp and aiding the survival of nerve cells. Unsurprisingly then, studies have shown that people with Alzheimer's disease have a reduced level of CRF ... interrupting the hormone from binding on to the CRFR1 receptor blocked the improvement of memory normally promoted by exercise. However, in mice with Alzheimer's a repeated regime of moderate exercise restored the normal function of the CRF system allowing its memory enhancing effects. The results are in line with the idea that regular exercise is a means of improving one's ability to deal with everyday stress in addition to keeping mental abilities keen"

  • Overexpression of hepatic 5α-reductase and 11β-hydroxysteroid dehydrogenase type 1 in visceral adipose tissue is associated with hyperinsulinemia in morbidly obese patients - Metabolism. 2011 Jun 23 - "11-β-Hydroxysteroid dehydrogenase type 1 (11β-HSD1) converts cortisone to cortisol, mainly in the liver and visceral adipose tissue (VAT), and has been implicated in several metabolic disorders. The absence of systemic hypercortisolism in central obesity could be due to increased inactivation of cortisol to its tetrahydrometabolites by the hepatic enzymes 5α- and 5β-reductases ... Forty-one patients were recruited (age, 41.8 +/- 10.6 years; body mass index, 42.1 +/- 6.6 kg/m(2); 71% women). The expression of hepatic 5α- and 5β-reductases was positively correlated (r = +0.53, P = .004), and their expression levels were correlated with hepatic 11β-HSD1 expression (r = +0.61, P < .001 for 5α-reductase and r = +0.50, P < .001 for 5β-reductase). Hepatic 5α-reductase was associated with insulin (r = +0.34, P = .015). Visceral adipose tissue 11β-HSD1 expression was associated with glucose (r = +0.37, P = .025) and insulin (r = +0.54, P = .002). Our results showed that 5α-reductase and VAT 11β-HSD1 expressions were associated with insulinemia. These findings suggest that overexpression of 5α-reductase, through a higher inactivation of cortisol in the liver, could have a protective role in preserving hepatic sensitivity to insulin. The overexpression of liver reductases in obesity could be an adaptive response to an increase in cortisol production by the liver and visceral 11β-HSD1 to avoid systemic hypercortisolism"
  • New method to measure cortisol could lead to better understanding of development of common diseases - Science Daily, 5/2/11 - "Currently the standard method to measure cortisol levels is to take a blood or saliva sample. However, since cortisol is released in a circadian rhythm and with pulses throughout the day, levels can fluctuate considerably, meaning it is difficult to estimate an individual's long-term exposure to cortisol through blood and saliva tests alone ... hair cortisol levels correlated positively with waist to hip ratio (r=0.425, p=0.003) and waist circumference (r=0.392, p=0.007), meaning people with higher exposure to cortisol showed higher abdominal obesity ... measuring the amount of cortisol in hair can potentially be used to monitor a person's long-term exposure to cortisol"
  • Caffeinated Coffee Does Not Acutely Affect Energy Intake, Appetite, or Inflammation but Prevents Serum Cortisol Concentrations from Falling in Healthy Men - J Nutr. 2011 Feb 23 - "Our aim in this crossover study was to investigate the acute effects of caffeinated and decaffeinated coffee consumption on appetite feelings, energy intake, and appetite-, inflammation-, stress-, and glucose metabolism-related markers. Sixteen healthy men (age range, 21-39 y; BMI range, 19.7-28.6 kg/m(2)) received in a random order on 3 separate occasions a standard breakfast snack with 200 mL of either caffeinated coffee (3 mg caffeine/kg body weight), decaffeinated coffee, or water (control). Before intervention (-15 min) and at standard time points following breakfast consumption (0, 15, 30, 60, 90, 120, 150, and 180 min), participants recorded their appetite feelings and we collected blood samples for measurements of circulating glucose, insulin, cortisol, and appetite- and inflammation-related markers. At 180 min, participants consumed a meal ad libitum. The appetite-related ratings, the appetite plasma hormonal responses as well as the plasma glucose, serum insulin, and plasma and serum inflammatory marker responses did not show an overall intervention effect or a time x intervention interaction. Ad libitum energy intake did not differ among the 3 interventions. However, a significant intervention effect (P = 0.04) and a time x intervention interaction (P-interaction = 0.02) were found for serum cortisol; cortisol concentrations were significantly higher following the caffeinated coffee intervention, compared to control, at 60 min and thereafter. In conclusion, the usually consumed amount of caffeinated coffee does not have short-term effects on appetite, energy intake, glucose metabolism, and inflammatory markers, but it increases circulating cortisol concentrations in healthy men"
  • Association of Diurnal Patterns in Salivary Cortisol with All-Cause and Cardiovascular Mortality: Findings from the Whitehall II Study - J Clin Endocrinol Metab. 2011 Feb 23 - "We assessed all-cause, cardiovascular, and noncardiovascular death. Results: There were 139 deaths, 32 of which were deaths due to cardiovascular disease, during a mean follow-up period of 6.1 yr. Flatter slopes in cortisol decline across the day were associated with increased risk of all-cause mortality (hazard ratio for 1 sd reduction in slope steepness 1.30; 95% confidence interval (CI) = 1.09-1.55). This excess mortality risk was mainly driven by an increased risk of cardiovascular deaths (hazard ratio = 1.87; 95% confidence interval = 1.32-2.64). The association with cardiovascular deaths was independent of a wide range of covariates measured at the time of cortisol assessment. There was no association between morning cortisol, the cortisol awakening response, and mortality outcomes. Conclusions: These findings demonstrate, for the first time, the relationship between a flatter slope in cortisol levels across the day and an increased risk of cardiovascular disease mortality in a nonclinical population"
  • Simple spit and blood tests might detect burnout before it happens - Science Daily, 2/21/11 - "In addition to professional and personal suffering, burnout puts distressed workers at further risk of physical and psychological problems if ignored ... We hypothesized that healthy workers with chronic stress and with mild burnout symptoms would have worse physiological dysregulations and lower cortisol levels -- a profile consistent with burnout ... Cortisol is a stress hormone involved in our bodies stress response and naturally as part of our body's daily rhythm. Cortisol levels are often high in people suffering from depression, while it tends to be low in cases of burnout. Too much cortisol can be as bad as too little when it comes to both mental and physical health ... Critically, people with burnout are often treated with anti-depressant medications that lower cortisol levels. If cortisol is already lower than it should be, this course of treatment could represent a therapeutic mistake. "The use of an allostatic load index gives researchers and clinicians a window to see how chronic stress is straining the person"
  • Cortisol, dehydroepiandrosterone sulphate, their ratio and hypertension: evidence of associations in male veterans from the Vietnam Experience Study - J Hum Hypertens. 2011 Feb 10 - "Cortisol and the cortisol:DHEAS ratio were positively associated with hypertension (P<0.001), whereas DHEAS was negatively associated; the latter relationship was attenuated to non-significance (P=0.06) in models that adjusted for age, sociodemographics, place of service, health behaviours and BMI. The present analyses provide confirmation of a positive association between cortisol and the cortisol:DHEAS ratio and population hypertension"
  • Behavioral problems linked to cortisol levels: Study finds intervention needed as soon as behavioral problems appear - Science Daily, 2/9/11 - "Some youngsters with behavioral problems have abnormally high levels of cortisol, while others with identical problems have abnormally low levels ... Cortisol levels were abnormally high around the time problem behaviours began, but abnormally low when they had been present for a long time ... Problem behaviours were classified as either "internalizing" (depression and anxiety) or "externalizing" (aggression, attentional problems) ... Youngsters who developed depression-like symptoms or anxiety problems in adolescence had high levels of cortisol. However, those who developed symptoms earlier had abnormally low cortisol levels. The conclusion? Cortisol levels go up when individuals are first stressed by depression or anxiety, but then decline again if they experience stress for an extended period"

  • Persistent organic pollutants affect the stress hormone cortisol - Science Daily, 12/28/10 - "persistent organic pollutants (POPs), such as PCB and mixtures of different POPs, affect the way the adrenal cortex functions and thereby the synthesis of the stress hormone cortisol ... altered cortisol balance during early life may lead to a predisposition to develop several diseases in adulthood, such as diabetes and cardiovascular diseases"
  • Promising drug candidate reverses age-related memory loss in mice - Science Daily, 10/12/10 - "Such memory loss has been linked with high levels of 'stress' steroid hormones known as glucocorticoids which have a deleterious effect on the part of the brain that helps us to remember. An enzyme called 11beta-HSD1 is involved in making these hormones and has been shown to be more active in the brain during aging ... We found that life-long partial deficiency of 11beta-HSD1 prevented memory decline with aging. But we were very surprised to find that the blocking compound works quickly over a few days to improve memory in old mice suggesting it might be a good treatment for the already elderly ... We previously showed that carbenoxolone, an old drug that blocks multiple enzymes including 11beta-HSD1, improves memory in healthy elderly men and in patients with type 2 diabetes after just a month of treatment, so we are optimistic that our new compounds will be effective in humans. The next step is to conduct further studies with our preclinical candidate to prove that the compound is safe to take into clinical trials, hopefully within a year"
  • High stress hormone levels linked to increased cardiovascular mortality - Science Daily, 9/9/10 - "urinary cortisol did not increase the risk of non-cardiovascular mortality but did increase cardiovascular mortality risk.

  • Urinary Cortisol and Six-Year Risk of All-Cause and Cardiovascular Mortality - J Clin Endocrinol Metab. 2010 Aug 25 - "During a mean follow-up of 5.7 (SD = 1.2) yr, 183 persons died, of whom 41 died from cardiovascular disease. After adjustment for sociodemographics, health indicators, and baseline cardiovascular disease, urinary cortisol did not increase the risk of noncardiovascular mortality, but it did increase cardiovascular mortality risk. Persons in the highest tertile of urinary cortisol had a five times increased risk of dying of cardiovascular disease (hazard ratio = 5.00; 95% confidence interval = 2.02-12.37). This effect was found to be consistent across persons with and without cardiovascular disease at baseline"

  • Cabergoline monotherapy in the long-term treatment of Cushing's disease - Eur J Endocrinol. 2010 Aug 11 - "Within 3-6 months, complete response was achieved in 11 patients (36.6%) and partial response in 4 (13.3%). After longer term therapy, 9 patients (30%) remain with a complete response after a mean of 37 months (range from 12-60 months) with a mean dose of 2.1 mg/wk of cabergoline. Two patients escaped after 2 and 5 years of complete response, but one transiently renormalized UFC after an increase in cabergoline dosage. No long-term response was maintained in 4 initial partial responders. Conclusions: Cabergoline monotherapy can provide an effective long-term medical therapy for selected patients with CD, but requires close follow-up for dose adjustments"

Our results support the hypothesis that increased total cortisol exposure is independently associated with atherosclerosis of the carotid arteries"
  • Stress Hormone Found To Regulate Brain Neurotransmission - Science Daily, 8/7/08 - "When we are subjected to a stress, our adrenal glands secrete hormones that affect our entire body. One of these hormones, cortisol, enables us to adapt physically and mentally to the stimulus. Following a major or repeated stress that the individual has no control over, however, cortisol is secreted in great quantities over a long period of time. This hypersecretion has damaging effects on the individual, to the point of accelerating aging and facilitating the onset of illnesses such as depression"
  • Depression can trigger diabetes, study suggests - MSNBC, 6/17/08 - "Depressed people were 42 percent more likely to develop diabetes ... depression also pushes up the levels of stress hormones such as cortisol ...
