Early Detection, Treatment Needed To Reduce Risk Of Death, Cardiovascular Disease In Cushing’s Disease Patients

Even after successful treatment, patients with Cushing’s disease who were older when diagnosed or had prolonged exposure to excess cortisol face a greater risk of dying or developing cardiovascular disease, according to a recent study accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM).

Cushing’s disease is a rare condition where the body is exposed to excess cortisol – a stress hormone produced in the adrenal gland – for long periods of time.

Researchers have long known that patients who have Cushing’s disease are at greater risk of developing and dying from cardiovascular disease than the average person. This study examined whether the risk could be eliminated or reduced when the disease is controlled. Researchers found that these risk factors remained long after patients were exposed to excess cortisol.

“The longer patients with Cushing’s disease are exposed to excess cortisol and the older they are when diagnosed, the more likely they are to experience these challenges,” said Eliza B. Geer, MD, of Mount Sinai Medical Center and lead author of the study. “The findings demonstrate just how critical it is for Cushing’s disease to be diagnosed and treated quickly. Patients also need long-term follow-up care to help them achieve good outcomes.”

The study found cured Cushing’s disease patients who had depression when they started to experience symptoms of the disease had an elevated risk of mortality and cardiovascular disease. Men were more at risk than women, a trend that may be explained by a lack of follow-up care, according to the study. In addition, patients who had both Cushing’s syndrome and diabetes were more likely to develop cardiovascular disease.

The study examined one of the largest cohorts of Cushing’s disease patients operated on by a single surgeon. The researchers retrospectively reviewed charts for 346 Cushing’s disease patients who were treated between 1980 and 2011. Researchers estimated the duration of exposure to excess cortisol by calculating how long symptoms lasted before the patient went into remission. The patients who were studied had an average exposure period of 40 months.

The findings may have implications for people who take steroid medications, Geer said. People treated with high doses of steroid medications such as prednisone, hydrocortisone or dexamethasone are exposed to high levels of cortisol and may experience similar conditions as Cushing’s disease patients.

“While steroid medications are useful for treating patients with a variety of conditions, the data suggests health care providers need to be aware that older patients or those who take steroid medications for long periods could be facing higher risk,” Geer said. “These patients should be monitored carefully while more study is done in this area.”

Adrenal Insufficiency – Female Patient found Unconscious with Syringe Nearby

Crew’s misdiagnosis of drug overdose could have cost patient her life

Kimberly Doran | From the October 2012 Issue |

 

A call comes in to 9-1-1 dispatch. “Help” is all that’s spoken before the operator hears the phone hit the floor. The 9-1-1 dispatcher calls back only to get a busy signal. Police and EMS are dispatched for a well-being call.

On arrival, the front door is found to be slightly ajar. The crew knocks, but there’s no reply. They find a young woman  lying on the floor, naked, and in a pool of vomit. A syringe with an unknown substance is on the ground nearby. Suspecting a drug overdose, the EMS crew begins treating the patient for this condition. The patient is unconscious with emesis around her head and face. Her vital signs are blood pressure 60/45, heart rate of 130 bpm and respiratory rate of 10.

The patient shows no signs of waking. The crew clears the airway and administers oxygen. An IV is established, and the patient is readied for transport. As the crew leaves the scene, one of the medics turns to shut the door and sees a vial under a chair. He retrieves it and notes that the label says Solu-Cortef (a glucocorticoid). He bags it for the emergency department (ED). Following his instinct, he looks around the area for medications and finds two bottles. One is labeled dexamethosone and the other is labeled fludrocortisone. He takes his findings and rushes out the door into the awaiting ambulance. During transport, the patient continues to deteriorate.

The medic administers 0.5 mg of narcan and a 500mL bolus of normal saline with no response. He radios ahead to let the hospital know that they’re en route. Now questioning the original diagnosis of drug overdose, he reports the medications he found on the scene in hopes it will help the receiving physician determine the cause of the patient’s condition.

Arrival at the ED
On arrival to the ED, the medic hands over the loaded syringe containing 2mL of unidentified solution, as well as the empty vial of Solu-Cortef and the bottles of dexamethosone and fludrocortisones.

As the crew arrives at the hospital, the ED physician meets the crew and informs them that he’s familiar with the medications. He says they’re all used for people who have various forms of adrenal insufficiency (AI). The symptoms seen in this patient coincide with life-threatening adrenal crisis. The physician administers 100 mg of Solu-Cortef via IV and within minutes, the patient rouses. In 30 minutes, she can explain what happened in the desperate moments before her crisis.

Adrenal Insufficiency
Adrenal Insufficiency (AI) is a life-threatening in which the body is unable to produce enough cortisol to sustain life. In other words, their adrenal cortex is “asleep.” People suffering from AI take daily cortisol/glucocorticoid steroid replacement because whatever adrenal function is depleted. These patients are glucocorticoid dependent. In times of injury, dehydration, illness or surgery, they require an injection of Solu-Cortef. Solu-Cortef contains both glucocorticoid and mineralocorticoid properties, helping the body to compensate during a stress event.

The adrenal medulla (inside of the adrenal gland) secretes epinephrine and norepinephrine. The adrenal cortex (outer layer of the adrenal gland) secretes cortisol and aldosterone. Cortisol, a glucocorticoid, is often called the “stress” hormone. One of cortisol’s functions is elevating blood glucose levels in times of stress. It also functions as a mediator for several inflammatory pathways.

Absence of cortisol can result in hypotension, hypoglycemia and death. Aldosterone, a mineralocorticoid, is responsible for the regulation of sodium and water. Absence of aldosterone can result in hypotension and electrolyte imbalance. AI in the prehospital setting may be difficult to recognize in the absence of a good history, including medications, to point providers in the cause of the problem. Two life-threatening conditions associated with AI include hypotension and hypoglycemia.

If not managed, these two conditions are life threatening. Prehospital treatment should include management of the patient’s airway, vascular access and fluid resuscitation. If blood glucose levels are low, the patient should receive dextrose per local protocol. It’s important to complete a thorough physical assessment and obtain a complete patient history before treating patients with this condition. Providers may confuse patients having an adrenal crisis with drug overdose patients because of their similar symptoms. Although AI is rare, it should still be considered as a potential diagnosis.

Authors’ noteParts of the above case are taken from a true story. However, the difference is that there was no syringe on the floor, no vial under the chair and no one found the medications. The patient was treated with charcoal and diagnosed as a drug-overdose patient. She likely would have died, but her mother charged into the ED and expressed the need for Solu-Cortef. Security was called, but luckily someone listened, researched and called the patient’s treating physician. The patient was treated and released.

Day Eleven, Cushing’s Awareness Challenge

In March of 1987, after the endo finally  confirmed that I had Cushing’s, I saw sent to a local hospital where they repeated all those same tests for another week and decided that it was not my adrenal gland (Cushing’s Syndrome) creating the problem. The doctors and nurses had no idea what to do with me, so they put me on the brain cancer ward.

When I left this hospital after a week, we didn’t know any more than we had before.

As luck would have it, NIH (National Institutes of Health, Bethesda, Maryland) was doing a clinical trial of Cushing’s. I live in the same area as NIH so it was not too inconvenient but very scary at first to think of being tested there. At that time I only had a choice of NIH, Mayo Clinic and a place in Quebec to do this then-rare pituitary surgery called a Transsphenoidal Resection.

My husband asked my endo if it were his wife, if he would recommend this surgery.  The endo responded that he was divorcing his wife – he didn’t care what happened to her.  Oh, my!

I chose NIH – closest and free. After I was interviewed by the Doctors there, I got a letter that I had been accepted into the clinical trial.

The night before I was admitted, I signed my will.  I was sure I was going to die there.  If not during testing, as a result of surgery.

The first time I was there was for 6 weeks as an inpatient. More of the same tests.

There were about 12 of us there and it was nice not to be alone with this mystery disease. Many of these Cushies (mostly women) were getting bald, couldn’t walk, having strokes, had diabetes. One was blind, one had a heart attack while I was there. Several were from Greece.

Towards the end of my testing period, I was looking forward to the surgery just to get this whole mess over with – either a cure or dying. While I was at NIH, I was gaining about a pound a day!

During the time I was home the weekend  before surgery, a college classmate of mine (I didn’t know her) DID die at NIH of a Cushing’s-related problem. I’m so glad I didn’t find out until reading the alumnae magazine a couple months later!  She was the same class, same major, same home-town, same disease…

We have a Scottish doctor named James Lind to thank for the clinical trial.  He  conducted the first ever clinical trial in 1747 and developed the theory that citrus fruits cured scurvy.  Lind  compared the effects of various different acidic substances, ranging from vinegar to cider, on groups of afflicted sailors, and found that the group who were given oranges and lemons had largely recovered from scurvy after 6 days.

I’d like to think that I advanced the knowledge of Cushing’s at least a little bit by being a guinea  pig in 1987-1989.

Hope through Research

Several components of the National Institutes of Health (NIH) conduct and support research on Cushing’s syndrome and other disorders of the endocrine system, including the National Institute of Diabetes and Digestive and Kidney Diseases, the National Institute of Child Health and Human Development (NICHD), the National Institute of Neurological Disorders and Stroke, the National Cancer Institute, and the National Center for Research Resources.

NIH-supported scientists are conducting intensive research into the normal and abnormal function of the major endocrine glands and the many hormones of the endocrine system. Researchers continue to study the effects of excess cortisol, including its effect on brain structure and function. To refine the diagnostic process, studies are under way to assess the accuracy of existing screening tests and the effectiveness of new imaging techniques to evaluate patients with ectopic ACTH syndrome. Researchers are also investigating jugular vein sampling as a less invasive alternative to petrosal sinus sampling. Research into treatment options includes study of a new drug to treat the symptoms of Cushing’s syndrome caused by ectopic ACTH secretion.

Studies are under way to understand the causes of benign endocrine tumor formation, such as those that cause most cases of Cushing’s syndrome. In a few pituitary adenomas, specific gene defects have been identified and may provide important clues to understanding tumor formation. Endocrine factors may also play a role. Increasing evidence suggests that tumor formation is a multistep process. Understanding the basis of Cushing’s syndrome will yield new approaches to therapy.

The NIH supports research related to Cushing’s syndrome at medical centers throughout the United States. Scientists are also treating patients with Cushing’s syndrome at the NIH Clinical Center in Bethesda, MD. Physicians who are interested in referring an adult patient may contact Lynnette Nieman, M.D., at NICHD, 10 Center Drive, Room 1-3140, Bethesda, MD 20892-1109, or by phone at 301-496-8935. Physicians interested in referring a child or adolescent may contact Constantine Stratakis, M.D., D.Sc., at NICHD, 10 Center Drive, Room 1-3330, Bethesda, MD 20892-1103, or by phone at 301-402-1998.

 

Day Nine, Cushing’s Awareness Challenge

UVA 2004
Cushing’s Conventions have always been special times for me – we learn a lot, get to meet other Cushies, even get referrals to endos!

As early as 2001 (or before) my pituitary function was dropping.  My former endo tested annually but did nothing to help me with the symptoms.

In the fall of 2002 my endo refused to discuss my fatigue or anything at all with me until I lost 10 pounds. He said I wasn’t worth treating in my overweight condition and that I was setting myself up for a heart attack. He gave me 3 months to lose this weight. Those 3 months included Thanksgiving, Christmas and New Years.  Needless to say, I left his office in tears, again.

Fast forward 2 years to 2004.  I had tried for awhile to get my records from this endo. He wouldn’t send them, even at doctors’ or my requests.

I wanted to go see Dr. Vance at UVa but I had no records so she would’t see me until I could get them.

Finally, my husband went to the former endo’s office and threatened him with a court order, The office manager managed to come up with about 13 pages of records. For going to him from 1986 to 2001 including weeks and weeks at NIH and pituitary surgery, that didn’t seem like enough records to me.

In April of 2004, many of us from the message boards went to the UVa Pituitary Days Convention. That’s where the picture above comes in.  Other pictures from that convention are here.

By chance, we met a wonderful woman named Barbara Craven. She sat at our table for lunch on the last day and, after we learned that she was a dietitian who had had Cushing’s, one of us jokingly asked her if she’d do a guest chat for us. I didn’t follow through on this until she emailed me later. In the email, she asked how I was doing. Usually I say “fine” or “ok” but for some reason, I told her exactly how awful I was feeling.

Barbara emailed me back and said I should see a doctor at Johns Hopkins. I said I didn’t think I could get a recommendation to there, so SHE referred me. The doctor got right back to me, set up an appointment. Between his vacation and mine, that first appointment turned out to be Tuesday, Sept 14, 2004.

Just getting through the maze at Johns Hopkins was amazing. They have the whole system down to a science, moving from one place to another to sign in, then go here, then window 6, then… But it was very efficient.

My new doctor was wonderful. Understanding, knowledgeable. He never once said that I was “too fat” or “depressed” or that all this was my own fault. I feel so validated, finally.

He looked through my records, especially at my 2 previous Insulin Tolerance Tests. From those, he determined that my growth hormone has been low since at least August 2001 and I’ve been adrenal insufficient since at least Fall, 1999 – possibly as much as 10 years! I was amazed to hear all this, and astounded that my former endo not only didn’t tell me any of this, he did nothing. He had known both of these things – they were in the past records that I took with me. Perhaps that was why he had been so reluctant to share copies of those records. He had given me Cortef in the fall of 1999 to take just in case I had “stress” and that was it.

The new endo took a lot of blood (no urine!) for cortisol and thyroid stuff. I went back on Sept. 28, 2004 for arginine, cortrosyn and IGF testing.

He said that I would end up on daily cortisone – a “sprinkling” – and some form of GH, based on the testing the 28th.

For those who are interested, my new endo is Roberto Salvatori, M.D.
Assistant Professor of Medicine at Johns Hopkins

Medical School: Catholic University School of Medicine, Rome, Italy
Residency: Montefiore Medical Center
Fellowship: Cornell University, Johns Hopkins University
Board Certification: Endocrinology and Metabolism, Internal Medicine

Clinical Interests: Neuroendocrinology, pituitary disorders, adrenal disorders

Research Interests: Control of growth hormone secretion, genetic causes of growth hormone deficiency, consequences of growth hormone deficiency.

Although I have this wonderful doctor, a specialist in growth hormone deficiency at Johns Hopkins, in November, 2004, my insurance company saw fit to over-ride his opinions and his test results based on my past pharmaceutical history! Hello??? How could I have a history of taking GH when I’ve never taken it before?

Of course, I found out late on a Friday afternoon. By then it was too late to call my case worker at the drug company, so we had to appeal on Monday. My local insurance person also worked on an appeal, but the whole thing was  just another long ordeal of finding paperwork, calling people, FedExing stuff, too much work when I just wanted to start feeling better by Thanksgiving.

As it turned out the insurance company rejected the brand of hGH that was prescribed for me. They gave me the ok for a growth hormone was just FDA-approved for adults on 11/4/04. The day this medication was approved for adults was the day after my insurance said that’s what is preferred for me. In the past, this form of hGH was only approved for children with height issues. Was I going to be a ginuea pig again?

The new GH company assigned a rep for me, submitted info to pharmacy, and waited for insurance approval, again.

I finally started the Growth Hormone December 7, 2004.

Was the hassle and 3 year wait worth it?

Stay tuned for Day 12, April 12, 2012 when all will be revealed.

Day Four, Cushing’s Awareness Challenge

The Seven Dwarves of Cushing's

So, these are only seven of the many, many symptoms of Cushing’s.  I had those above – and I often felt like I looked like one of those little bearded dwarves.

Cushing’s affects every part of the body.  It’s not like when I had kidney cancer and only the kidney was affected.

Here’ are some of the many areas affected.

  • Progressive obesity and skin changes
  • Weight gain and fatty tissue deposits, particularly around the midsection and upper back, in the face (moon face) and between the shoulders (buffalo hump). Some symptoms such as sudden weight gain, are caused by excess cortisol. The excess cortisol in the body does not increase protein and carbohydrate metabolism. It slows or nearly disables metabolism function, which can cause weight gain (fat accumulation) in the buttocks, abdomen, cheeks, neck, or upper back.
  • Loss of muscle mass. Some areas of the body, such as the arms and legs, will remain thin.
  • Pink or purple stretch marks (striae) on the skin of the abdomen, thighs, breasts and arms
  • Thinning, fragile skin that bruises easily
  • Slow healing of cuts, insect bites and infections
  • Acne

Women with Cushing’s syndrome may experience:

  • Thicker or more visible body and facial hair (hirsutism)
  • Irregular or absent menstrual periods

Men with Cushing’s syndrome may experience:

  • Decreased libido
  • Decreased fertility
  • Erectile dysfunction

Other signs and symptoms include:

  • Fatigue
  • Muscle weakness
  • Depression, anxiety and irritability
  • Loss of emotional control
  • Cognitive difficulties
  • New or worsened high blood pressure
  • Glucose intolerance that may lead to diabetes
  • Headache
  • Bone loss, leading to fractures over time
  • Hyperlipidemia (elevated lipids – cholesterol – in the blood stream)
  • Recurrent opportunistic or bacterial infections
Think you have Cushing’s?  Get to a doctor and don’t give up!
