Experts recommend tumor removal as first-line treatment for Cushing’s syndrome

Posted on July 30, 2015 by MaryO

The Endocrine Society today issued a Clinical Practice Guideline (CPG) on strategies for treating Cushing’s syndrome, a condition caused by overexposure to the hormone cortisol.

The CPG, entitled “Treatment of Cushing’s Syndrome: An Endocrine Society Clinical Practice Guideline,” was published online and will appear in the August 2015 print issue of the Journal of Clinical Endocrinology and Metabolism (JCEM), a publication of the Endocrine Society.

Cushing’s syndrome occurs when a person has excess cortisol in the blood for an extended period, according to the Hormone Health Network. When it is present in normal amounts, cortisol is involved in the body’s response to stress, maintains blood pressure and cardiovascular function, keeps the immune system in check, and converts fat, carbohydrates and proteins into energy. Chronic overexposure to the hormone can contribute to the development of cardiovascular disease, infections and blood clots in veins.

People who take cortisol-like medications such as prednisone to treat inflammatory conditions, including asthma and rheumatoid arthritis, can develop Cushing’s syndrome. The high cortisol levels return to normal when they stop taking the medication. This is called exogenous Cushing’s syndrome.

In other cases, tumors found on the adrenal or pituitary glands or elsewhere in the body cause the overproduction of cortisol and lead to the development of Cushing’s syndrome. The Clinical Practice Guidelines focus on this form of the condition, known as endogenous Cushing’s syndrome.

“People who have active Cushing’s syndrome face a greater risk of death – anywhere from nearly twice as high to nearly five times higher – than the general population,” said Lynnette K. Nieman, MD, of the National Institutes of Health’s Eunice Kennedy Shriver National Institute of Child Health and Human Development in Bethesda, MD, and chair of the task force that authored the guideline. “To reduce the risk of fatal cardiovascular disease, infections or blood clots, it is critical to identify the cause of the Cushing’s syndrome and restore cortisol levels to the normal range.”

In the CPG, the Endocrine Society recommends that the first-line treatment for endogenous Cushing’s syndrome be the removal of the tumor unless surgery is not possible or unlikely to address the excess cortisol. Surgical removal of the tumor is optimal because it leaves intact the hypothalamic-pituitary-adrenal axis, which is integral to the body’s central stress response.

Other recommendations from the CPG include:

  • Tumors should be removed by experienced surgeons in the following situations:— A tumor has formed on one or both of the two adrenal glands.— A tumor that secretes adrenocorticotropic hormone (ACTH) – the hormone that signals the adrenal glands to produce cortisol – has formed somewhere in the body other than the adrenal or pituitary gland.

    — A tumor has formed on the pituitary gland itself.

  • Patients who continue to have high levels of cortisol in the blood after surgery should undergo additional treatment.
  • People who had an ACTH-producing tumor should be screened regularly for the rest of their lives for high cortisol levels to spot recurrences.
  • If patients’ cortisol levels are too low following surgery, they should receive glucocorticoid replacement medications and be educated about adrenal insufficiency, a condition where the adrenal glands produce too little cortisol. This condition often resolves in 1-2 years.
  • Morning cortisol and/or ACTH stimulation tests, or insulin-induced hypoglycemia, can be used to test for the recovery of the hypothalamic-pituitary-adrenal axis in people who have low cortisol levels after surgery. Once the tests results return to normal, glucocorticoid replacement can be stopped.
  • People who have undergone pituitary surgery should be re-evaluated for other pituitary hormone deficiencies during the post-operative period.
  • Patients who have a pituitary tumor and have undergone surgery to remove both adrenal glands should be regularly evaluated for tumor progression using pituitary MRIs and tests for ACTH levels.
  • Radiation therapy may be used to treat a pituitary tumor, especially if it is growing. While awaiting the effect of radiation, which may take months to years, treatment with medication is advised.
  • To assess the effect of radiation therapy, the patient’s cortisol levels should be measured at 6- to 12-month intervals.
  • Medications may be used to control cortisol levels as a second-line treatment after surgery for a pituitary gland tumor, as a primary treatment for ACTH-secreting tumors that have spread to other parts of the body or suspected ACTH-secreting tumors that cannot be detected on scans. Medications also can be used as adjunctive treatment to reduce cortisol levels in people with adrenal cortical carcinoma, a rare condition where a cancerous growth develops in the adrenal gland.
  • People with Cushing’s syndrome should be treated for conditions associated with the disease, such as cardiovascular disease risk factors, osteoporosis and psychiatric symptoms.
  • Patients should be tested for recurrence throughout their lives except in cases where the person had a benign adrenal tumor removed.
  • Patients should undergo urgent treatment within 24 to 72 hours of detecting excess cortisol if life-threatening complications such as serious infection, pulmonary thromboembolism, cardiovascular complications and acute psychosis are present.

Adrenal insufficiency – how to spot this rare disease and how to treat it

Posted on June 6, 2015 by MaryO

adrenal-glandsAddison’s disease, or adrenal insufficiency, is a rare hormonal disorder of the adrenal glands that affects around 8,400 people in the UK.

The adrenal glands are about the size of a pea and perched on top of the kidneys, and affect the body’s production of the hormones cortisol and sometimes aldosterone.

When someone suffers from adrenal insufficiency, those glands aren’t producing a sufficient amount of these hormones. This can have a detrimental effect on someone’s health and well-being. But because the symptoms are similar to a host of other conditions, Addison’s disease can prove tough to isolate.

What to look out for

According to advice provided by the NHS, the symptoms in the early stages of Addison’s disease, which affects both men and women, are gradual and easy to misread as they’re similar to many other conditions.

People can experience severe fatigue, muscle weakness, low moods, loss of appetite, unintentional weight loss, low blood pressure, nausea, vomiting and salt craving.

“Symptoms are often misread or ignored until a relatively minor infection leads to an abnormally long convalescence, which prompts an investigation,” says Professor Wiebke Arlt from the Centre for Endocrinology, Diabetes & Metabolism at the University of Birmingham.

Life-threatening condition

If Addison’s disease is left untreated, the level of hormones produced by the adrenal gland will gradually decrease in the body. This will cause symptoms to get progressively worse and eventually lead to a potentially life-threatening situation called an adrenal, or Addisonian, crisis. Signs include severe dehydration; pale, cold, clammy skin; rapid, shallow breathing; extreme sleepiness; severe vomiting and diarrhoea. If left untreated, it can prove fatal, so the patient should be admitted to hospital as an emergency.

Back to basics

To understand the disorder, it’s important to get to grips with the basics and that means understanding what the adrenal glands are – and so to the science.

“Adrenal glands have an inner core (known as the medulla) surrounded by an outer shell (known as the cortex) ,” explains Arlt.
The inner medulla produces adrenaline, the ‘fight or flight’ stress hormone. While the absence of this does not cause the disease, the cortex is more critical.

“It produces the steroid hormones that are essential for life: cortisol and aldosterone,” he adds.

“Cortisol mobilises nutrients, enables the body to fight inflammation, stimulates the liver to produce blood sugar and also helps control the amount of water in the body. Aldosterone, meanwhile, regulates the salt and water levels, which can affect blood volume and pressure.”

Why does it happen?

The disorder occurs if the adrenal glands are destroyed, absent or unable to function and failure of the glands themselves is known as primary adrenal insufficiency.

“It’s most often caused by autoimmune disease where the body’s immune system mounts an attack against its own adrenal glands,” explains Arlt.

“However it can also be caused by infection, most importantly by tuberculosis and sometimes by both adrenal glands being surgically removed.”

The pituitary effect

Another important cause is any disease affecting the pituitary gland, which is located behind the nose at the bottom of the brain.
“The pituitary is the master gland that tells the other glands in the body what to do,” continues Arlt.

“The pituitary gland produces a hormone called ACTH (adrenocorticotropic hormone to give it its full name), which travels in the blood stream to the adrenal glands.

“Here it acts as a signal, causing the adrenal glands to produce more cortisol. If the pituitary gland stops making ACTH, [then] cortisol production by the adrenals is no longer controlled properly and a condition called secondary adrenal insufficiency arises.”

But in most cases, aldosterone is still produced, which means that people suffering from secondary adrenal insufficiency have fewer problems than those with primary adrenal insufficiency.

Determining a diagnosis

Due to the ambiguous nature of the symptoms, a Short Synacthen Test (SST) needs to be performed in order to diagnose adrenal insufficiency.

“This measures the ability of the adrenal glands to produce cortisol in response to (the pituitary hormone) ACTH,” says Arlt. “When carrying out this test, a baseline blood sample is drawn before injecting a dose of ACTH, followed by drawing a second blood sample 30 to 60 minutes later. Failing adrenal glands will not be able to produce a certain level of cortisol.”

Getting treatment

If someone has been conclusively diagnosed with adrenal insufficiency, they should receive adrenal hormone replacement therapy as advised by an endocrinologist, a doctor specialising in hormone-related diseases.

“A normal adrenal gland does not need supplements to function properly and there is no recognised medical condition called ‘adrenal fatigue’,” warns Arlt.

“Either the adrenal gland is fine and needs no treatment or there is adrenal insufficiency due to adrenal or pituitary failure.”

So if in doubt, don’t self-diagnose but book an appointment with your GP.

Enzyme that triggers muscle wasting could be key to REVERSING signs of ageing | Daily Mail Online

Posted on May 21, 2015 by MaryO

Drawing on expertise from both the University of Birmingham and Queen Elizabeth Hospitals Birmingham, they applied their knowledge of Cushing’s syndrome to the new problem (sarcopenia).

Cushing’s is hormonal disorder caused by high levels of cortisol. Patients suffer from the syndrome see marked changes in their body composition.

The effects can be devastating for patients who can develop features such as muscle wasting and weakness, weight gain, thinning of the bones, diabetes, high blood pressure and heart disease.

Dr Hassan-Smith said: ‘Looking at this particular enzyme seemed like an intriguing way forward.

‘We knew how it works in relation to Cushing’s Syndrome, which is characterised by similar symptoms, and thought it would be worthwhile applying what we knew to the ageing population.’

Currently there are no treatments for sarcopenia, the team explained.

But pharmaceutical companies are developing and testing ways to block or switch off the enzyme, with a focus on treatments for conditions including diabetes.

The team is excited about taking the results of their study forward into future research, with one eye on adapting the inhibitors already in development to combat muscle ageing.

Dr Hassan Smith added: ‘The next stage is a “proof of concept” study to look at the effects of these inhibitive pharmaceuticals on muscle function, before opening it up into a clinical trial.

‘It’s an as yet unexplored area that could yield beneficial results for a problem that is becoming more prevalent as our lifespans increase.’

The study was published in the journal of Clinical Endocrinology and Metabolism.

Interview May 13 with Michelle B (MichelleB), Cyclic Cushing’s Patient

Posted on May 13, 2015 by MaryO

Hello all, I’m Michelle mother of 3 beautiful children, I work part-time, 33yrs young, non-smoker, non-drinker, overall health is good for the most part…..Where do I even begin.

I just recently received the diagnosis of cyclic Cushing’s. I’m not really sure how long I have actually had Cushing’s because I have had a diagnosis of PCOS since I was 17 yrs. old ( I’m now the ripe young age of 33). However looking back through labs with my endocrinologist who I see every 6 months, my ACTH levels have been elevated for a bit over 1 yr. It was not until recently January of 2015- things were going terribly wrong.

Starting in January I started to feel genuinely unwell, on a regular basis. I cant really explain all my symptoms there were so many different sensations and feelings that were seemingly different daily. However the red flag was I was having blood pressure spikes from really high, to very low back to back. I never had any blood pressure issues so this was a concern that led me to see a cardiologist. Upon tons of testing the cardio MD felt that something was telling my otherwise very healthy heart to do this and I should see a endocrinologist. (thank goodness for him) I contacted my endo and let him know…. the testing began.

I did every test: the midnightcortisol saliva test, dex suppression, 24 hr urine test, CRH stimulation testing. And I did them more than once. Each time it was a different response either, inconclusive, normal high, or high. I was then referred to the head of the Cleveland clinics pituitary department Dr. Kennedy. He said he is having a hard time believing when he looks at me that its Cushing’s. However all my labs say it is. I will say I do fit the mold of PCOS to a tee- which symptoms of that do coincide with Cushing’s but he still said we have to be sure its Cushing’s. To add to the mix I did have a normal MRI as well.

Dr. Kennedy started me on a 2 week midnight cortisol saliva test- Upon completion we noted levels of cortisol all over the place, some Normal, normal on high range, high, and really high. He confirmed with all the other tests this is Cushing’s. Now we are trying to figure out what is next…. and where is this damn little tumor at. he feels that it is most likely in the pituitary from my test results, but we still are not ruling out else where. He is thinking that the next step would be exploratory neurosurgery or the IPSS. I’m not sure what to think of all this, except I want to hope for the best like everyone- and just be cured!!

On a side note during all of this I also had episodes of severe pain in my chest and nausea. I went to see a GI who did an upper endo scope. They found I had eosinpphilic esophagitis. I also have never had any GI problems until now; and they came on suddenly. Im also having pain in my pancreas area- not sure if any of the two are related at all to Cushing’s. But once again I was fine until recently with all these issues at once it seems.

wish me luck on further testing, treatment, and ultimately a CURE!!

Clinical Trial for Cortendo

Posted on March 13, 2015 by MaryO

Cortendo Clinical Trial

 

About the Study

OBJECTIVE:

The purpose of this study is to test the effects of different doses of COR-003 on people with endogenous Cushing’s syndrome, primarily by measuring the cortisol levels in urine and secondarily by measuring other health parameters such as blood pressure, weight, liver function, etc. This study is also being conducted to find out if COR-003 is safe to use. This study is open-label, which means both the health providers and the participants in the study are aware of the drug or treatment being given.

STUDY DESIGN:

  • The study will begin with a screening period to make sure subjects are eligible to participate in the study.
  • After the screening period, subjects who are eligible for participation will each be given several different doses of COR-003, to be taken by mouth in tablet form.
  • After an individualized dose has been selected, participants will take COR-003 for 6 months.
  • Finally, participants will continue in the study for an additional 6 months at doses to be determined by the study doctor.
  • Throughout the study, participants will meet regularly with a study doctor and will take part in a variety of medical tests to make sure they are doing well and to see if COR-003 is working.
  • Participants in the study should be sure they have the time to participate. Participants will generally be followed for over a year.
