Cushing’s disease best treated by endocrinologist

Dear Dr. Roach: I was told that I have Cushing’s disease, which has caused diabetes, high blood pressure, hunger, weight gain and muscle loss. I was never sick before this, and I did not have any of those things. I am told I have a tumor on my right adrenal gland. I have been to numerous doctors, but most have not been too helpful. They seem to try to treat the diabetes or blood pressure, but nothing else. They seem not to be familiar with Cushing’s. I tell them which medication works, but they still give me new medication. I have an endocrinologist and am scheduled to meet a urologist.

I have managed to go to physical therapy, exercise every day and lose over 50 pounds. I am not happy with the advice I’m getting. I was told that surgery to remove the tumor will fix everything, but that I would need to take steroids for either a short term or for life. My body is already making too much cortisol. I have 50 more pounds to lose. I work hard to keep the weight down. I feel like a science experiment. Within a week, I have had three different medications. I could not tell which was causing the side effects and making me dehydrated. I am not sure surgery is right for me, because they said it can be done laparoscopically, but if they can’t do it that way, they will have to cut me all the way across, which may take a long time to heal and may get infected.

Do you know what tests will confirm the diagnosis? Would surgery fix all these problems? I had the 24-hour urine test, the saliva test and blood tests. I want to know if it may be something else instead of Cushing’s. I’m not on anything for the high cortisol levels.

– A.L.

A: It sounds very much like you have Cushing’s syndrome, which is caused by excess cortisone, a hormone that has many effects. It is called Cushing’s disease when the underlying cause is a pituitary tumor that causes the adrenal gland to make excess cortisone. (Cortisone and cortisol are different names for the same chemical, also called a glucocorticoid.) Cushing’s syndrome also may be caused by an adenoma (benign tumor) of the adrenal gland, which sounds like the case in you.

The high amounts of cortisone produced by the adrenal tumor cause high blood pressure, glucose intolerance or frank diabetes, increased hunger, obesity (especially of the abdomen – large bellies and skinny limbs are classic), dark-colored striae (stretch marks), easy bruising, a reddish face and often weakness of arm and leg muscles. When full-blown, the syndrome is easy to spot, but many people don’t have all the characteristics, especially early in the course of the disease.

Your endocrinologist is the expert in diagnosis and management, and has done most of the tests. I am somewhat surprised that you haven’t yet seen a surgeon to have the tumor removed. Once it is removed, the body quickly starts to return to normal, although losing the weight can be a problem for many.

I have seen cases in my training where, despite many tests, the diagnosis was still uncertain. The endocrinologist orders a test where the blood is sampled from both adrenal veins (which contain the blood that leaves the adrenal glands on top of the kidneys). If the adrenal vein on the side of the tumor has much more cortisone than the opposite side, the diagnosis is certain.

Adiponectin level may serve as predictor of subclinical Cushing’s syndrome

Unal AD, et al. Int J Endocrinol. 2016;doi:10.1155/2016/8519362.

 

In adults with adrenal incidentaloma, adiponectin levels may help predict the presence of subclinical Cushing’s disease, according to recent findings.

Asli Dogruk Unal, MD, of the department of endocrinology and metabolism at Memorial Atasehir Hospital in Istanbul, and colleagues analyzed data from 40 patients with adrenal incidentaloma (24 women; mean age, 61 years) and 30 metabolically healthy adults without adrenal adenomas or hyperplasia (22 women; mean age, 26 years). All patients with type 2 diabetes were newly diagnosed and not on any antidiabetic therapies; included patients were not using statin therapy for about 12 weeks.

Participants provided blood samples

Among patients with adrenal incidentaloma, eight (20%) were diagnosed with subclinical Cushing’s syndrome; median adenoma diameter in these patients was 3.05 cm. The remaining patients were classified as nonfunctional adrenal incidentaloma. Compared with patients who had nonfunctional adrenal incidentaloma, patients with subclinical Cushing’s syndrome had a higher median midnight cortisol level (9.15 µg/dL vs. 5.1 µg/dL; P = .004) and urinary free cortisol level (249 µg per 24 hours vs. 170 µg per 24 hours; P = .007).

In two group comparisons, researchers found that only adiponectin level was lower in the subclinical Cushing’s syndrome group vs. the nonfunctional adrenal incidentaloma group (P = .007); there were no observed between-group differences for age, BMI, waist circumference, insulin levels, homeostasis model assessment for insulin resistance (HOMA-IR) or lipid profiles.

Adiponectin level was negatively associated with insulin level, HOMA-IR, triglyceride level and midnight cortisol level, and was positively associated with body fat percentage, HDL and adrenocorticotropic hormone levels. In linear regression analysis, age was found to be an increasing factor, whereas sex, HOMA-IR, LDL, waist circumference and presence of subclinical Cushing’s syndrome were decreasing factors.

In evaluating the receiver operating characteristic analysis, researchers found that adiponectin level had a predictive value in determining the presence of subclinical Cushing’s syndrome (area under the curve: 0.81; 95% CI, 0.67-0.96). Sensitivity and specificity for an adiponectin value of 13 ng/mL or less in predicting the presence of subclinical Cushing’s syndrome were 87.5% and 77.4%, respectively; positive predictive value and negative predictive value were 50% and 96%, respectively.

“Presence of [subclinical Cushing’s syndrome] should be considered in case of an adiponectin level of 13 ng/mL in [adrenal incidentaloma] patients,” the researchers wrote. “Low adiponectin levels in [subclinical Cushing’s syndrome] patients may be important in treatment decision due to the known relation between adiponectin and cardiovascular events. In order to increase the evidences on this subject, further prospective follow-up studies with larger number of subjects are needed.” – by Regina Schaffer

“How can you leave her like this?”

A mother has revealed the anguish her family suffered after her daughter (16), who is in need of brain surgery, was turned away from Beaumont Hospital.

The National Centre for Neurosurgery had no beds or theatre access for nine patients with malignant brain tumours last Friday.
One of the people who was turned away was 16-year-old Chloe Holian from Donegal.

Her mother Caitriona explained to the Anton Savage Show on TodayFM that the road to treatment has been fraught with setbacks.

“I can’t stress how happy I am with the neurosurgeon and his team are there but it seems our consultant’s hands are tied, what am I supposed to do?” she said.

Chloe was diagnosed in July with a recurrence of Cushing’s syndrome, a metabolic disorder which is caused by abnormally high levels of the hormone cortisol in the blood stream.

After being promised treatment in July and then August, the Letterkenny girl was finally admitted on Thursday and was fasting for a procedure on Friday morning when she was told it was cancelled.

“When we got down they told us that they decided to put off the surgery for a couple of days,” said Caitriona.

She was told that the doctors wanted to perform a dexamethasone suppression test first to confirm that Chloe was, in fact, suffering from Cushing’s – despite previous diagnosis revealing that she was.

However, she soon found out that the test couldn’t be performed.

“At 11am someone in scrubs came around to say it wasn’t fair but he had to tell us she won’t be doing the surgery… and she wouldn’t be getting the major test either,” said Caitriona.

She said he was very empathetic of their situation.

“I felt sorry for him having to tell us that news… I asked him ‘how can you leave her like this?’

“He promised that he was going to organise this test himself. It was quite difficult as you need four people in the surgery to do this test, you need the radiographer, neurosurgeon, endocrinologist and anesthetist.”

Unfortunately, an anesthetist was not available for the test.

Caitriona said that Chloe was quite upset at the news. One of the side-effects of her condition is excessive weight gain and the student has gained six stone since last September.

“She had psyched herself up for the surgery,” explained her mother.

“Everybody was around her encouraging her, they threw a party for her before she went because it was a big thing. Chloe has no confidence because she’s put on an extra six stone. She was looking forward to getting her old self back, she just wanted to go and do this operation and get it over and done with.

“For anybody to have a little bit of a weight gain they can be conscious of it but if you’re 16-years-old and you’ve gained six stone and you can’t explain it…”

Caitriona said the family were forced to pack their bags and return to Donegal but, as of today, they have still not received a rescheduled appointment.

The mother-of-three is struggling to juggle home life with trips to Dublin but she said the family’s life is on hold until the tumour is removed.

This is the second time that Chloe has developed Cushing’s, in 2009 she was sent to London for surgery as treatment was not yet available in Ireland.

Patients lives are being threatened by delays, according to the head of the country’s national brain surgery centre. Clinical Director Mohsen Javadpour says people are at risk of dying while they’re waiting for treatment.

Cushing’s Syndrome and Skin Problems

By Afsaneh Khetrapal, BSc (Hons)

Cushing’s Syndrome (sometimes called hypercortisolism) is a hormonal disease caused by an abnormally high level of the hormone cortisol in the body. This may arise because of an endogenous or exogenous source of cortisol. Endogenous causes include the elevated production of cortisol by the adrenal glands, while exogenous causes include the excessive use of cortisol or other similar steroid (glucocorticoid) hormones over a prolonged period of time.

The adrenal glands are situated just above each kidney, and form part of the endocrine system. They have numerous functions such as the production of hormones called catecholamines, which includes epinephrine and norepinephrine. Interestingly, the outer layer (cortex) of the adrenal glands has the distinct responsibility of producing cortisol. This hormone is best known for its crucial role in the bodily response to stress.

At physiologically appropriate levels, cortisol is vital in maintaining normal sleep-wake cycles, and acts to increase blood sugar levels. It suppresses the immune system, regulates the effect of insulin on the metabolism of fats, proteins, and carbohydrates, and help with the homeostasis of water in the body.

Exogenous corticosteroids can also lead to Cushing’s syndrome, when they are used as a form of long-term treatment for various medical conditions. In fact, the long-term use of steroid medication is the most common reason for the development of Cushing’s syndrome.

Prednisolone is the most commonly prescribed steroid medicine. It belongs to a class of medicine that is sometimes used to treat conditions such as certain forms of arthritis and cancer. Other uses include the rapid and effective reduction of inflammation in conditions such as asthma and multiple sclerosis (MS), as well as the treatment of autoimmune conditions such as lupus erythematosus, and rheumatoid arthritis.

Overall, Cushing’s syndrome is quite uncommon and affects approximately 1 in 50,000 people. Most of them are adults between the ages of 20 and 50.  Women are 3 times more commonly affected than men. Additionally, patients who are obese, or those who have type 2 diabetes with poorly controlled blood sugar and blood pressure show a greater predisposition to the disorder.

Symptoms of Cushing’s syndrome

There are numerous symptoms associated with Cushing’s syndrome, which range from muscle weakness, hypertension, curvature of the spine (kyphosis), osteoporosis, and depression, to fatigue Specific symptoms which pertain to the skin are as follows:

  • Thinning of the skin and other mucous membranes: the skin becomes dry and bruises easily. Cortisol causes the breakdown of some dermal proteins along with the weakening of small blood vessels. In fact, the skin may become so weak as to develop a shiny, paper-thin quality which allows it to be torn easily.
  • Increased susceptibility of skin to infections
  • Poor wound healing  of bruises, cuts, and scratches
  • Spots appear on the upper body, that is, on the face, chest or shoulders
  • Darkened skin which is seen on the neck
  • Wide, red-purple streaks (at least half an inch wide) called striae which are most common on the sides of the torso, the lower abdomen, thighs, buttocks, arms, and breasts, or in areas of weight gain. The accumulation of fat caused by Cushing’s syndrome stretches the skin which is already thin and weakened due to cortisol action, causing it to hemorrhage and stretch permanently, healing by fibrosis.
  • Acne: this can develop in patients of all ages.
  • Swollen ankles: this is caused by the accumulation of fluid, called edema.
  • Hyperhidrosis (excessive sweating)

Who’s at Risk for Cushing’s?

by Kristen Monaco
Contributing Writer, MedPage Today

Researchers have developed a new method to assess specific populations for Cushing’s syndrome, based on results from a multicenter study.

The prospective cohort study evaluated at-risk patients for Cushing’s syndrome to create a novel type of scoring system in order to better predict the development of disease, stated lead author Antonio León-Justel, PhD,of the Seville Institute of Biomedicine in Spain, and colleagues.

Cushing’s syndrome is identified by an excess of cortisol and/or glucocorticoids in the blood, which can result in myriad negative health outcomes, including an increased risk of death and morbidity, according to the study in The Journal of Clinical Endocrinology & Metabolism.

Because Cushing’s syndrome (CS) is complex and difficult to diagnose, there is a necessity for new methods to assess at-risk populations in order to mitigate the rising prevalence of the disorder, the authors noted.

“The diagnosis of CS might pose a considerable challenge even for experienced endocrinologists since there are no pathognomonic symptoms or signs of CS and most of the symptoms and signs of CS are common in the general population including obesity, hypertension, bone loss, and diabetes,” the senior author, Alfonso Leal Cerro, MD, toldMedPage Today via email. “Routine screening for CS remains impractical due to the estimated low prevalence of the disease. However this prevalence might be higher in at-risk populations.”

The authors screened a total of 353 at-risk patients from 13 different hospitals across Spain between January 2012 and July 2013 to measure cortisol variability from saliva samples.

At-risk populations, which the authors note have a higher prevalence of Cushing’s syndrome, included individuals with type 2 diabetes, hypertension, and osteoporosis.

The patients screened in the study were each identified as having at least two of the risk factors for Cushing’s syndrome: high blood pressure (defined as taking two or more drugs and having a systolic blood pressure over 140 mmHg and/or a diastolic blood pressure over 90 mmHg), obesity (body mass index >30), uncontrolled diabetes (HbA1c>7.0%), osteoporosis (T-score ≥ -2.5 SD), and virilization syndrome (hirsutism) with menstrual disorders.

The researchers used clinical and biochemical methods of assessment. Clinical methods included inspection of physical characteristics, such as muscle atrophy, purple striae, and/or facial plethora. Biochemical methods included collecting saliva and blood samples from participants to test cortisol levels using a chemiluminescence method. Each individual was identified as either negative for hypercortisolism (late-night salivary cortisol [LNSC] ≤ 7.5 nmol/L and dexamethasone suppression test [DST] ≤ 50 nmol/L) or positive for hypercortisolism (LNSC > 7.5 nmol/L and DST > 50 nmol/L).

Univariate testing indicated the following significant characteristics to be positively correlated with the development of Cushing’s syndrome:

  • Muscular atrophy (15.2, CI 95% 4.48-51.25);
  • Osteoporosis (4.60, 1.66-12.75); and
  • Dorsocervical fat pad (3.32, 1.48-7.5).

A logistic regression analysis of LNSC values also showed significant correlation between Cushing’s syndrome and the following top three characteristics:

  • Muscular atrophy (9.04, CI 95% 2.36-34.65);
  • Osteoporosis (3.62, CI 95% 1.16-11.35); and
  • Dorsocervical fat pad (3.3, CI 95% 1.52-7.17).

Roberto Salvatori, MD, professor and medical director of the Johns Hopkins Pituitary Center, who was not involved with the study, commented to MedPage Today in an email: “Any endocrinologist would proceed with careful Cushing biochemical evaluation in the presence of the clinical features (muscular atrophy, osteoporosis, and dorsocervical fat pad) that are well known to be associated with hypercortisolism. Of notice, the odds ratio is further increased by an abnormal late-night salivary cortisol, which is already a screening test for hypercortisolism.”

The researchers used their results to develop an equation to determine the level of risk a patient has for developing Cushing’s syndrome, taking into account factors for osteoporosis, dorsocervical fat pads, muscular atrophy, and LNSC levels.

Although the study was able to develop a comprehensive risk model for the syndrome, when tested against the prevalence for Cushing’s syndrome in the subject group, the equation generated a total of 56 false-positive and 25 true-positive results. Overall, the researchers wrote, 83% of patients were accurately classified as belonging to the at-risk population when using the equation.

Because the newly developed equation for identifying at-risk individuals involved factors that are relatively easy to test for, the authors noted that clinical application is broad and cost-effective in a primary care setting.

“We would like to test the scoring system in different clinical settings such as primary care or hypertension clinics,” Leal Cerro said. “Primary care would be a particularly interesting setting since it might significantly decrease the time to diagnosis, something critical to avoid an excessive exposure to glucocorticoid excess and consequent deleterious effects.”

Salvatori said that while the study was a good start at shedding light on some of the unknowns about Cushing’s syndrome, more research is required. “The real question in my mind is when does a non-endocrinologist need to suspect Cushing in a general medicine, orthopedic, or other clinic? When the internal medicine residents ask me about guidelines for ‘who to screen for hypercortisolism in my clinic,’ I am unable to provide an evidence-based answer.”

The study was funded by a grant from Novartis Oncology, Spain.

León-Justel and Leal Cerro disclosed financial relationships with Novartis Oncology, Spain.
