Remaining calm = Reducing illness

Posted on October 9, 2013 by MaryO

Have you ever noticed that when you are “stressed” you can feel either emotionally/physically depleted or energized?  When our body is under stress the brain responds by producing epheniphrine or adrenaline, sending signals to our adrenal glands, increasing the rate at which our heart beats while releasing oxygen to our muscles.  The long term response to this process produces cortisol (aka the stress hormone) facilitating the release of energy throughout our body.  However, when our body isn’t properly balanced these hormones can wreak havoc on our wellness possibly resulting in one of three conditions:  Cushing’s syndrome, Cushing’s disease or Addison’s disease.

adrenal-glandsThe actual Adrenal glands sit physically atop both kidneys, taking on a triangular shape and a roundish rectangular type shape.  These glands are responsible for our sex hormones and cortisol, helping us respond to stress amongst other functions.  When our body is under stress, physically and/or nutritionally, it responds one of two ways:  Produces too much or too little of the cortisol hormone.  Our Adrenal glands also contribute to regulating our blood sugar, blood pressure, salt and water.

Adrenal disorders can cause our body to make too much or not enough of these hormones, bringing about adrenal gland related syndromes and disease.  Cushing’s syndrome results from our body making too much versus Addison’s disease produces too little.

Cushing’s syndrome vs. Cushing’s disease

Glucocorticoids (naturally produced in our body or received through medicine) are groups of corticosteroids (cortisol or dexamethasone) involved in metabolizing our carbohydrate and protein.  When taken synthetically (i.e. treatment of allergies, skin problems, and respiratory problems) or over-produced naturally, the side effects can result in “Cushing’s syndrome”.

Cushing’s syndrome can occur one of two ways:  Endogenous or Exogenous.  Endogenous is caused by the body (usually through tumors).  Exogenous is caused by medication.  In both cases, the body produces too much cortisol.

Symptoms: Severe fatigue/muscle weakness, high blood sugar and high blood pressure, upper body obesity, thin arms/legs, bruising easily

Treatment:  The cure and treatment for Cushing’s disease can come through medicine, surgery, or by lowering the dosage of your current synthetic hormone treatment.  Cushing’s syndrome can be cured.

Cushing’s disease is the most common form of endogenous Cushing’s syndrome and is likely treatable.  Caused by a tumor in the pituitary gland secreting too much Adrenocorticotropic hormone (ACTH), this type of tumor does not spread and can be removed through surgery.

Nutrition:  See a nutritionist or dietician for your condition.  Mostly, avoid excess sodium.  High blood sugar (hyperglycemia) and high blood pressure can easily occur with this condition.  Bone loss density is common with this condition, so be extra aware of your calcium (800 – 1200 mg per day, based upon age) and Vitamin D intake (5mcg from age 0-50, increasing up to 10 mcg 50-71, and 15 mcg after 71).  Eating healthy, balanced and whole food (versus processed) is extremely important.

Addison’s disease

Opposite from Cushing’s syndrome, Addison’s disease doesn’t make “enough” of the sex hormones and cortisol.  The result of this disease causes our immune system to attack our tissue, damaging our adrenal glands.

Symptoms:  Weight loss, muscle weakness, increasingly worse fatigue, low blood pressure and patchy or dark skin.

Treatment:  If left untreated, the condition can be fatal.  Lifetime hormone treatment is usually required. Addison disease patients should always carry medical/emergency ID on them, listing their medication, dosage and disease

Lab tests can confirm that you have Addison’s disease. If you don’t treat it, it can be fatal. You will need to take hormone pills for the rest of your life. If you have Addison’s disease, you should carry an emergency ID. It should say that you have the disease, list your medicines and say how much you need in an emergency.”

(Ref: http://www.nlm.nih.gov/medlineplus/cushingssyndrome.html, NIH: National Institute of Neurological Disorders and Stroke)                                                                                                                                                                                                                                        Learning how to balance our stress-filled lives is extremely important to our overall health.  Healthy nutrition always contributes benefits to our overall wellness.  We can overwhelm our endocrine system by simply not eating nutritionally.  Understanding that “Food is a drug” is vitally important to how we help our body naturally heal itself.  The above two conditions are the result of our body not handling the stress we are putting it through, causing our body to producing too much or too little of the sex hormones and cortisol.

Unless we first address what we can do naturally through nutrition, the medicine we consume will only do so much in helping our body heal completely.  You simply cannot continue doing the same thing over and over again, expecting the medicine to do all the work.  Some diseases are brought upon us through our environment (emotionally as well as physically) as well as our diet/nutrition.  Reviewing our entire wellness is always wisdom whenever we’re diagnosed with anything.

Certainly listen to your doctor and their advice.  But also ask your doctor to refer you to a nutritionist or clinical/registered dietician for a complete evaluation that includes a review of your nutritional diet/wellness.  Too often we reach for a pill or a procedure to “fix” our health problems, ignoring what we should be doing on our own to help our body heal.  Medical intervention is the result of providing our body with what it cannot produce on its own.  Nutrition should always be the “natural” medicine we take, as well as what we might need through prescribed medication.

Abstract

Background: The outcome of bilateral adrenalectomy (BADx) in patients with Cushing’s syndrome (CS) is not well characterized.

Methods: A literature search was performed with the search terms “bilateral adrenalectomy” or “total adrenalectomy” and “Cushing’s” or “Cushing.” Immediate and long-term outcomes after BADx in CS were analyzed using descriptive statistics (median [range]).

Results: From 549 screened publications, 37 studies met inclusion criteria (1320 patients, 82% having Cushing’s disease [CD], 13% having ectopic CS, and 5% having primary adrenal hyperplasia).

Surgical morbidity and mortality of BADx (23 studies, 739 patients) were 18% (6–31) and 3% (0–15), respectively. In patients with CD, surgical mortality was below 1%. Although residual cortisol secretion due to accessory adrenal tissue or adrenal remnants was found in 3–34% (5 studies, 236 patients), less than 2% had a relapse of CS.

Symptoms of hypercortisolism (eg, hypertension, obesity, or depression) improved in the majority of the patients after BADx (7 studies, 195 patients). The number of adrenal crises per 100 patient-years was 9.3 (6 studies, 203 patients).

Nelson’s syndrome occurred in 21% (0–47) of the patients (24 studies, 768 patients). Mortality (23 studies, 690 patients) was 17% (0–88) at a follow-up of 41 months (14–294). Remarkably, 46% of the patients died in the first year after surgery. The median ages at death were 62 years (CD) and 53 years (ectopic CS).

Conclusion: BADx is relatively safe and provides adequate success. Excess mortality within the first year after surgery suggests that intensive clinical care for patients after BADx is warranted.

Enzyme linked to obesity

Posted on September 11, 2013 by MaryO

Researchers find that increased levels of an enzyme in fat cells lead to dangerous levels of abdominal obesity.

Previous studies have shown that the stress hormone cortisol can lead to an accumulation of fat round the abdomen. For instance, people with Cushing’s disease – where there’s excess cortisol in the blood – have too much abdominal fat. It’s bad for health to have fat in this area – it’s linked to diabetes and heart disease. That’s why it’s healthier to be a ‘pear shape’ rather than an ‘apple shape’. The distribution of fat in your body really does matter.

Researchers in Scotland and the US have now focussed upon an enzyme that produces cortisol to see what effect it has on abdominal fat. Working on mice genetically-modified to produce the enzyme – and therefore cortisol – in fat cells, they find that even a small increase in levels produces dramatic effects. The mice, compared with normal animals, gained fat in the abdominal area even on a low fat diet. They developed diabetes, high blood pressure, and also tended to eat more. It opens up the possibility of further studies on human obesity, and also perhaps could lead to therapies that block this enzyme and so reduce fat accumulation.

When to think Cushing’s syndrome in type 2 diabetes

Posted on July 28, 2013 by MaryO

ESTES PARK, COLO. – Diabetes mellitus, osteoporosis, and hypertension are conditions that should boost the index of suspicion that a patient with some cushingoid features may in fact have endogenous Cushing’s syndrome, Dr. Michael T. McDermott said at a conference on internal medicine sponsored by the University of Colorado.

An estimated 1 in 20 patients with type 2 diabetes has endogenous Cushing’s syndrome. The prevalence of this form of hypercortisolism is even greater – estimated at up to 11% – among individuals with osteoporosis. In hypertensive patients, the figure is 1%. And among patients with an incidentally detected adrenal mass, it’s 6%-9%, according to Dr. McDermott, professor of medicine and director of endocrinology and diabetes at the University of Colorado.

“Endogenous Cushing’s syndrome is not rare. I suspect I’ve seen more cases than I’ve diagnosed,” he observed. “I’ve probably missed a lot because I failed to screen people, not recognizing that they had cushingoid features. Not everyone looks classic.”

There are three screening tests for endogenous Cushing’s syndrome that all primary care physicians ought to be familiar with: the 24-hour urine cortisol test, the bedtime salivary cortisol test, and the overnight 1-mg dexamethasone suppression test.

“I think if you have moderate or mild suspicion, you should use one of these tests. If you have more than moderate suspicion – if a patient really looks like he or she has Cushing’s syndrome – then I would use at least two screening tests to rule out endogenous Cushing’s syndrome,” the endocrinologist continued.

The patient performs the bedtime salivary cortisol test at home, obtaining samples two nights in a row and mailing them to an outside laboratory. The overnight dexamethasone suppression test entails taking 1 mg of dexamethasone at bedtime, then measuring serum cortisol the next morning. A value greater than 1.8 mcg/dL is a positive result.

Pregnant women constitute a special population for whom the screening method recommended in Endocrine Society clinical practice guidelines (J. Clin. Endocrinol. Metab. 2008;93:1526-40) is the 24-hour urine cortisol test. That’s because pregnancy is a state featuring high levels of cortisol-binding globulins, which invalidates the other tests. In patients with renal failure, the recommended screening test is the 1-mg dexamethasone suppression test. In patients on antiepileptic drugs, the 24-hour urine cortisol or bedtime salivary cortisol test is advised, because antiseizure medications enhance the metabolism of dexamethasone.

Dr. McDermott said that “by far” the most discriminatory clinical features of endogenous Cushing’s syndrome are easy bruising, violaceous striae on the trunk, facial plethora, and proximal muscle weakness.

“They’re by no means specific. You’ll see these features in people who don’t have Cushing’s syndrome. But those are the four things that should make you really consider Cushing’s syndrome in your differential diagnosis,” he stressed.

More widely recognized yet actually less discriminatory clinical features include facial fullness and the “buffalo hump,” supraclavicular fullness, central obesity, hirsutism, reduced libido, edema, and thin or poorly healing skin.

Endogenous Cushing’s syndrome can have three causes. An adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma accounts for 80% of cases. A cortisol-secreting adrenal tumor is the cause of 10%. And another 10% are due to an ectopic ACTH-secreting tumor, most commonly a bronchial carcinoid tumor.

Once the primary care physician has a positive screening test in hand, it’s typical to refer the affected patient to an endocrinologist in order to differentiate which of the three causes is present. This is accomplished based upon the results of a large, 8-mg dexamethasone suppression test coupled with measurement of plasma ACTH levels.

Dr. McDermott recommended as a good read on the topic of evaluating a patient with endogenous Cushing’s syndrome a recent review article that included a useful algorithm (N. Engl. J. Med. 2013;368:2126-36).

He reported having no financial conflicts.

Abstract

Identification of adults with GH deficiency (GHD) is challenging because clinical features of adult GHD are not distinctive and because clinical suspicion must be confirmed by biochemical tests.

Adults are selected for testing for adult GHD if they have a high pretest probability of GHD, ie, if they have hypothalamic-pituitary disease, if they have received cranial irradiation or central nervous system tumor treatment, or if they survived traumatic brain injury or subarachnoid hemorrhage.

Testing should only be carried out if a decision has already been made that if deficiency is found it will be treated. There are many pharmacological GH stimulation tests for the diagnosis of GHD; however, none fulfill the requirements for an ideal test having high discriminatory power; being reproducible, safe, convenient, and economical; and not being dependent on confounding factors such as age, gender, nutritional status, and in particular obesity.

In obesity, GH secretion is reduced, GH clearance is enhanced, and stimulated GH secretion is reduced, causing a false-positive result. This functional hyposomatotropism in obesity is fully reversed by weight loss. In conclusion, GH stimulation tests should be avoided in obese subjects with very low pretest probability.
