Predictors of Mortality, CVD Risk in Cushing’s Disease ID’d

(HealthDay News) – A number of factors, including the duration of glucocorticoid exposure, older age at diagnosis, and preoperative adrenocorticotropic hormone (ACTH) concentration, are associated with a higher risk of mortality in patients treated for Cushing’s disease (CD), according to research published online Feb. 7 in the Journal of Clinical Endocrinology & Metabolism.

In an effort to identify predictors of mortality, cardiovascular disease, and recurrence with long-term follow-up, Jessica K. Lambert, MD, of the Mount Sinai Medical Center in New York City, and colleagues performed a retrospective chart review of 346 patients with CD who underwent transsphenoidal adenectomy.

The researchers found that the average length of exposure to glucocorticoids was 40 months. The risk of death was higher for those patients who had a longer duration of glucocorticoid exposure, older age at diagnosis, and higher preoperative ACTH concentration. For patients who achieved remission, depressed patients had a higher risk of death. The risk of cardiovascular disease was highest for men, older people, and those with diabetes or depression.

“Our study has identified several predictors of mortality in patients with treated CD, including duration of exposure to excess glucocorticoids, preoperative ACTH concentration, and older age at diagnosis. Depression and male gender predicted mortality among patients who achieved remission,” the authors write. “These data illustrate the importance of early recognition and treatment of CD. Long-term follow-up, with management of persistent comorbidities by an experienced endocrinologist, is needed even after successful treatment of CD.”

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.”

Day Six, Cushing’s Awareness Challenge

People sometimes ask me how I found out I have Cushing’s.  Theoretically, it was easy.  In practice, it was very difficult.

Ladies Home Journal, 1983In 1983 I came across a little article in the Ladies Home Journal which said “If you have these symptoms…”

I found the row with my symptoms and the answer read “…ask your doctor about Cushing’s”.

After that article, I started reading everything I could on Cushing’s, I bought books that mentioned Cushing’s. I asked and asked my doctors and all of them said was rejected each time.

 

 

Due to all my reading at the library, I was sure I had Cushing’s but no one would believe me. My doctors would say that Cushing’s Disease is too rare, that I was making this up and that I couldn’t have it.

In med school, student doctors are told “When you hear hoofbeats, think horses, not zebras“.  According to Wikipedia: “Zebra is a medical slang term for a surprising diagnosis. Although rare diseases are, in general, surprising when they are encountered, other diseases can be surprising in a particular person and time, and so “zebra” is the broader concept.

The term derives from the aphorism “When you hear hoofbeats behind you, don’t expect to see a zebra”, which was coined in a slightly modified form in the late 1940s by Dr. Theodore Woodward, a former professor at the University of Maryland School of Medicine in Baltimore.  Since horses are the most commonly encountered hoofed animal and zebras are very rare, logically you could confidently guess that the animal making the hoofbeats is probably a horse. By 1960, the aphorism was widely known in medical circles.”

So doctors typically go for the easily diagnosed, common diseases.  Just because something is rare doesn’t mean that no one gets it.  We shouldn’t be dismissed because we’re too hard to diagnose.

When I was finally diagnosed in 1987, 4 years later, it was only because I started bleeding under the skin. My husband made circles around the outside perimeter each hour with a marker so my leg looked like a cut log with rings.

When I went to my Internist the next day he was shocked at the size. He now thought I had a blood disorder so he sent me to a Hematologist/Oncologist. Fortunately, he ran a twenty-four hour urine test and really looked at me and listened to me.  Both he and his partner recognized that I had Cushing’s but, of course, couldn’t do anything further with me.  They packed me off to an endo where the process started again.

My final diagnosis was in October, 1987.  Quite a long time to simply  “…ask your doctor about Cushing’s”.

Looking back, I can see Cushing’s symptoms much earlier than 1983.  But, that ‘s for a different post.

 

Corlux in the news again

Associated Press

MENLO PARK, CALIF. — Corcept Therapeutics Inc. said Tuesday it expects to raise about $18 million by selling stock and options to institutional investors.

Corcept said the money will be used to complete enrollment of patients in a late stage clinical trial of its drug candidate Corlux as a treatment for Cushing’s syndrome, and to cover the cost of filing for Food and Drug Administration marketing clearance.

The $18 million is a gross estimate and does not include expenses connected to the offering.

Corcept said it will sell 12.6 million units at $1.43 per share. The units will consist of one share of stock, and a warrant to buy 0.35 shares at an exercise price of $1.66 per share. Buyers include current Corcept investors such as Longitude Capital Management, Sutter Hill Ventures, Alta Partners and new investors including Federated Kaufmann Funds.

The sale is expected to close on Friday.

The company is testing Corlux as a treatment for Cushing’s syndrome and psychotic depression. Cushing’s syndrome occurs when the body produces to much of the hormone cortisol, or by overexposure to cortisol. Symptoms can include high blood sugar and blood pressure, fatigue, and weak muscles.
