The Seven Dwarves of Cushing's

 

Posted Oct. 1st, 2015 by Clare Rowson

Q: Would you please explain Cushing’s disease. How is it diagnosed? What are the symptoms?

A: Cushing syndrome results from excess levels of the hormone cortisol. It is produced in various glands, usually the adrenal that is situated above the kidneys on both sides, and the pituitary gland, which is in the centre of the brain.

Cortisol also regulates the way fats, carbohydrates and proteins are turned into usable forms of energy. These glands produce other hormones that affect things such as blood pressure and the body’s response to stress.

Cortisol may be added from outside the body by taking medications such as prednisone, often used for the control of chronic inflammatory or autoimmune diseases like lupus or rheumatoid arthritis.

Prednisone is also used for the treatment of acute illnesses such as severe allergies. Poison ivy is often treated this way.

Women in the last three months of pregnancy also have increased blood levels of cortisol and may temporarily display some of symptoms of Cushing’s syndrome.

Any problem with the pituitary gland, the nearby hypothalamus in the brain or adrenals can lead to Cushing’s syndrome. The most common is a benign tumour of the pituitary gland known as a pituitary adenoma.

This type of tumour may produce an excessive amount of a stimulating hormone known as ACTH, which in turn activates the hormones in the adrenal glands. On rare occasions, some types of lung or thyroid cancer can also behave in a similar way.

The most obvious sign of Cushing’s disease is marked weight gain, mostly in the abdomen, face and neck, while the arms and legs remain relatively thin.

As the skin in these areas becomes thinner, there may be purple coloured stripes or stretch marks. Women may also lose their periods and grow facial or body hair.

Blood pressure is usually high and sufferers feel weak and tired.

Cushing’s disease is diagnosed by measuring the amount of cortisol in a person’s urine during a 24 hour period.

If there is a tumour it will require surgical removal. If Cushing’s syndrome is a result of prescribed medication, the dosage can be reduced gradually or another type of medication can be tried. Prednisone must never be suddenly discontinued or the person’s blood pressure could drop dramatically, which could be serious and potentially fatal.

Well it has taken me a year to write this bio…and just to give some hope to those of you just going thru this process…I have to say that after surgery I have not felt better! I am back to who i always knew I was….the depression and anxiety is gone and I am living life like a 24 year old should!

I guess it all started when i was sixteen (hindsight is 20-20 i guess). My periods stopped i was tired all the time and the depression started. We all kind of just chalked it up to being sixteen. But my mom insisted something was not right. we talked with my gyno…who said nothing was wrong, I had a fungus on my head (my hair was getting really thin) and sometimes girls who had normal periods (in my case three years of normal periods) just go awry.

My mom wasnt hearing that and demanded a script for an endo. I went….he did blood work…and metioned cushings. But nothing came back definitive…so they put me on birthcontol and gave me some hormones and the chushings was never mentioned again because that all seemed to work.

As time went on my depression got worse, the shape of my body started to change-my face and stomach was the most noticeable- and my energy level kept going down. I kept going back to the doctors asking to be tested for mono..or something. I went to a psycologist….but i knew there was no reason for my depression. Two of them told me “i had very good insight” and that I didnt need them. I started getting more anxiety..especially about going out socially.

High school ended and my typical optimistic personality started to decline. I put on a good act to my friends but my family was seeing me break down all the time. I went away for college (all the while gaining weight). My sophmore year I had a break down..I called my family crying that i needed help. I couldnt beat my depression. I didnt drink in college because i knew that would mean instant weight gain, i barely went out…i exercised everyday..hard….i joined weight watchers…i stuck with it. I was at 103 lbs….that crept up to 110…that crept up to 117…each time my weight goal would be “ohh if i could just get back to 108..112…115” with each weight gain my original weight goal would get higher and higher.

Internally i felt like I was constantly under a black cloud..i knew there was no reason why i shoudl feel this way..i was doing great in school, i had a supportive family, an amazing boyfriend and great friends…why was i depressed? I was becoming emotionally draining to the people closest to me…I would go home a lot on the weekends…i was diagnosed with PMDS….like severe PMS..and was given an antidepresant…i hated it it made me feel like a zombie…i stopped taking it and just made it apoint to work on fighting the depression….and the weight gain.

When i was done college i was about 120 lbs. My face was getting rounder and rounder..i was noticing more hair on my face and arms…and a hump between my shoulder blades and the bottom of my neck. My mom saw a tv show about Polycystic ovarian syndrome and felt that maybe that was what was going on with me…i went to my PCP with this and she said it was possible and that i should to talk to my gyno….I am 4’8 and at the time weighing close to 125..i talked to my gyno and she said I was not heavy..that i was just “itailan” ..i told her my periods were getting abnormal again even w/the birthcontrol and that i was so tired all the time and my arms and legs ached. I also told her that i was bruising very easily…and that the weight gain would not stop despite my exercising and following the atikins diet very strickly for over 6 weeks. My boyfriend and I decided to try the diet together..he lost 35 llbs in 6 weeks..i lost NOTHING! I went back to my PCP who ordered an ultra sound of my ovaries…..NOTHING.(i kept thinking i was going crazy and that it was all in my head)….she also decided to do some blood work…and as i was walking out the door she said..”you know what..i am going to give you this 24hr urine test too. Just so that we cover everything”. I just kept thinking please let something come back ….please dont let this be all my fault…please dont let this be all in my head…..please dont let me be crazy. When i got the test results back it turned out that the 24hr urine test was the one test i needed to get on the right track to finding what was wrong. My cortisol level was 3x’s the normal.

I went to an endo…by the time i got to the endocronoligist i was up to 130…i could not work a full day without needing a full day of sleep and my body was aching beyond description. I was crying all the time…in my room…and was becoming more and more of a recluse…i would only hang out with my boyfriend in our houses. I looked my symptoms up on the internet and saw cushings…that was it! I went to the endo and told him..i think it is cushings….he said he had only saw it one other time and that he wanted to do more tests. I got CAT scans, x-rays, MRI’s….my adrenals my pituitary my lungs….he did a CRH stimulation test which was getting blood work done every fifteen minutes for 90minutes….it took weeks to get that test scheduled..no one had ever heard of it and therefore did not know how to do it…..finally after 3 months of tests my dr. felt he had enough evidence to diagnos me with cushings disease (tumor on my pituitary) I was diagnosed in March of 2004. By this time i was about 137 lbs i had to work part time (i am an occupational therapist for children..i do home visits….i could not make it thru a whole day)

In April i had to change to office work…i could not lift the children and i could barely get up off the floor. I have to say i was one of the lucky people who worked for people who were very supportive and accomidating…my boss was very willing to work with me and willing to hold my job for me.

July 30th 2004 i finally had transphenodial surgery to remove my tumor (they went thru my lip and nose because they felt my nose was too small). It is now over 1 year later….i am down to 108 lbs, i have so much energy…no depression….and i dont mind looking at myself in the mirror…i am enjoying my friends and my boyfriend…(who stayed with me thru it all) And my family. I feel healthy mentally, emptionally, and physically. And i just got back into my size 2 jeans!!!

It was a crappy time…(as i am sure you all can atest to) but i learned a lot…..most importantly i was bombarded by good wishes and prayers….friends requested masses for me…a nun in brazil prayed for me…people who i never thought i touched their lives…took the time to wish me well…send an email..or call….I got to experience the wonderful loving nature of human beings and i was lucky to be supported by my family (my mom, dad, and two younger brothers) and my boyfriend throughout this entire tough journey.

This experience taught me to realize the strength i have as well as to appreciate the good and the bad in life. I was on hydrocortizone for about 8 months…i was lucky that my tumor was in its own little sack so my pituitary gland was not touched. In the end in took about 7 years to diagnose me..i think that if the dr. at 16 would have pursued the cushings idea nothing would have been found because it took so long for my symptoms to really peak…needless to say i love my PCP and my endo ..and that i changed gyno’s…

I just want to let anyone out there going thru this disease to know..you are not alone….and to take each day is stride…when you need help ask for it….and that this road can lead to a happy ending. God Bless!

ps- it is ok to feel bad about what you are going thru…it is a tough thing to endure…and when the docotors tell you there is noting wrong…..follow your gut…and you keep searching for the doctor that will listen… If there is anyone in the philadelphis of south jersey area who needs someone to talk to please feel free to email me…fapadula@hotmail.com…i will help you out the best i can!

Update November 6, 2011

Well- here is an update, after seven years of being Cushings free it has returned.

With in those seven years I married my college boyfriend and we now have a son- Nicholas who will be 2 in Decemeber. It has been a blessed and wonderful seven years. However right around when my son was turning 1 I started to notice symptoms again. Increase facial hair, the whole “roundness” of my body, buffalo hump. I decided I was going to work out hard, eat right, and see – I didnt just want to jump to any conclusions. I stuck to it- and nothing…..my hair started thinning again and the acne was coming back and then the missed periods…..so I went to my PCP- told them i needed the 24hr urine and wouldnt you know…..427 cortisol level (on that 0-50 scale)……here we go again.

So back to endo- now at Penn Pituitary Center…..it was another journey b/c the tumor wasnt definative on MRI, and it seems to be cycling…..but I was diagnosed with Cushings again- with the option of 2nd pit surgery or BLA…….after some months of trying to make a decision I went with the 50/50 chance of the second pituitary surgery on 10/26/2011.

It didnt work- my levels never came down in the hospital and I went home w/ out of range cortisol levels and no need for medication……BLURG……Sooooo on to the next step…..after I recover from this surgery I will most likely have the BLA- with the hopes of not having to deal with Cushings ever again. This time around has been a little more difficult just with being a mom and feeling sick- but I still continue to be amazingly blessed with a supportive family and husband and we are surrounded by love and support and for that I am beyond greatful.

I keep all of you in my prayers for relief and health- as I ( we all) know this no easy journey.

Many Blessings!

Fabiana

Update September 12, 2015

So to bring this up to date. My second pituitary surgery in 2011 was unsuccessful. January of 2012 I had both of my adrenal glands removed. Going to adrenal insufficiency was a very difficult transition for me. It took me nearly 2 years before I felt functional. As time went on I felt more human, but I haven’t felt healthy since that day. I can and do function, but at a lower expectation of what I used to be capable of….my “new normal”.

My husband and I decided to try for a second child…my pituitary was damaged from the second surgery and we needed fertility…after 8 months of fertility I got pregnant and we had our second son January of 2015.

In April of 2015 we discovered that my ACTH was increasing exponentially. MRI revealed a macroadenoma invading my cavernous sinus. The tumor is sitting on my carotid artery and milimeterrs away from my optic chasim. I was not a candidate for another surgery due to the tumors proximity to.both of those vital structures.

So September 1st of this year I started daily radiation treatments. I spent my 34th birthday getting my brain zapped. I am receiving proton beam therapy at the Hospital of the University of Pennsylvania. I am so lucky to live so close to an institute that has some of the rarest treatment options.

Again Cushing’s is disrupting our life, my husband goes with me every night to radiation while family takes turns watching the kids….I am now on my 18th year of fighting this disease. I never imagined it would get to this point.

But here we all are making the best of each day, fighting each day and trying to keep things as “normal” as possible. Blessings to all of you fighting this disease…my new go to saying is” ‘effing Cushing’s”! For you newbies…Fight, Advocate for yourselves, and find a doc who doesn’t dismiss you and hang on to them for dear life.

Metopirone effective treatment for hypercortisolemia in Cushing’s syndrome

Posted on September 15, 2015 by MaryO

Hypercortisolemia in Cushing’s syndrome can be controlled with Metopirone therapy, according to recent study findings published in The Journal of Clinical Endocrinology & Metabolism.

John Newell-Price, PhD, FRCP, of the University of Sheffield in the United Kingdom, and colleagues evaluated 195 patients with Cushing’s syndrome to determine the effect of Metopirone (metyrapone, HRA Pharma) on the control of excess cortisol. Cushing’s syndrome was most commonly Cushing’s disease (n = 115), followed by ectopic adrenocorticotropic hormone (ACTH; n = 37), benign adrenal disease (n = 30), adrenocortical carcinoma (n = 10), ACTH-independent macronodular adrenal hyperplasia (n = 2) and primary pigmented nodular adrenal hyperplasia (n = 1).

The biochemical parameters of activity of Cushing’s syndrome were measured by mean serum cortisol day-curve (target, 150-300 nmol/L), early morning serum cortisol and 24-hour urinary free cortisol.

Most participants received monotherapy (n = 164) and had significant improvements in excess cortisol during treatment. Significant improvements were revealed from first to last review for cortisol day-curve, early morning cortisol and 24-hour urinary free cortisol.

At last review, 55% of participants who had cortisol day-curve, 43% who had urinary free cortisol, 46% who had early morning cortisol less than 331 nmol/L and 76% who had early morning cortisol less than the upper limit of normal/600 nmol/L achieved control.

The median final dose of metyrapone was 1,375 mg among those with Cushing’s disease, 1,500 mg among those with ectopic ACTH, 750 mg among those with benign adrenal disease and 1,250 among those with adrenocortical carcinoma.

Twenty-five percent of participants experienced adverse events, with the most common being mild gastrointestinal upset and dizziness. Most of the adverse events occurred within 2 weeks of initiation or dose increase and were reversible.

“Overall more than 80% of patients showed an improvement in levels of circulating cortisol with over 50% achieving biochemical eucortisolemia when on monotherapy when assessed by the stringent criterion of control on a [cortisol day-curve],” the researchers wrote. “It is likely that additional therapies were added because of the severity of disease and clinician preference, but the retrospective and multicenter nature of our study precludes a formal assessment of this. Furthermore, our data support that metyrapone monotherapy is an effective treatment for hypercortisolemia either before or after surgical intervention to the primary cause of [Cushing’s syndrome].” – by Amber Cox

Endocrine Society Releases Guidelines on Treatment of Cushing’s Syndrome

Posted on August 26, 2015 by MaryO

To lessen the risk for comorbidity and death, the Endocrine Society’s newly published guidelines on the treatment of Cushing’s syndrome focus on surgical resection of the causal tumor with the goal of normalizing cortisol levels. Furthermore, there is increased emphasis on individualizing treatment options when choosing a second-line treatment.

In July 2015, the Endocrine Society published treatment guidelines to assist endocrinologists in appropriately initiating treatment or referring patients with Cushing’s syndrome to treatment. A task force of experts compiled evidence from systematic reviews and graded the strength of the recommendations.

“We hope that it will lead to improved treatment of comorbidities both before and after definitive treatment of the syndrome, and to increased individualization of patient treatment,” said chair of the task force Lynnette Nieman, MD, who is chief of the Endocrinology Consultation Service at the National Institutes of Health Clinical Center.

“There are two new drugs that were approved in 2012, and so I think that is what prompted the review. Still, medications are not the first line of treatment, but we have some new therapeutic options, and I think the idea was to help people understand where to use them,” Julie Sharpless, MD, assistant professor and director of the UNC Multidisciplinary Pituitary Adenoma Program, told Endocrinology Advisor.

“The primary treatment is surgical resection of the causal tumor(s). If that cannot be done (because the tumor is occult or metastatic) or is not successful, then the choice of secondary treatment should be individualized to the patient. The comorbidities of Cushing’s syndrome, for example hypertension and diabetes, should be treated separately as well,” Nieman said.

For example, the guidelines recommend surgical removal of the causative lesion, with the exception of cases which are unlikely to cause a drop in glucocorticoids or in patients who are not surgical candidates.

Likewise, in patients with benign unilateral adrenal adenoma, adrenalectomy by an experienced surgeon has a high rate of cure in children and adults. Because of the poor prognosis associated with adrenal carcinoma, the guidelines highlight the need for complete resection and possibly medical treatment to stabilize cortisol levels.

Other first-line treatment options include recommending surgical resection of ectopic ACTH-secreting tumors; referring to an experienced pituitary surgeon for transsphenoidal selective adenomectomy; treatments to block hormone receptors in bilateral micronodular adrenal hyperplasia; and surgical removal in bilateral adrenal disorders.

The elevated mortality rate seen in patients with Cushing’s syndrome is due to infection, venous thrombosis and cardiovascular disease (CVD). Appropriately lowering cortisol levels improves hypertension, insulin resistance, dyslipidemia and obesity in patients with Cushing’s syndrome. Therefore, the guidelines highlight the need for restoring cortisol levels and treating the associated comorbidities.

Nevertheless, the task force specifically recommends against treatment without an established diagnosis or when there are no signs of Cushing’s syndrome and hypothalamic-pituitary-adrenal laboratory studies are borderline.

In patients who are not surgical candidates or in cases of noncurative resection, the decision on whether to consider second-line treatment options such as medical therapy, radiation, bilateral adrenalectomy or repeat transsphenoidal surgery should be based on several factors. For instance, the guidelines recommend taking into consideration location and size of the tumor, patient desires, goals of treatment and level of biochemical control.

The guidelines note medical therapy should be based on cost, efficacy and individualization of treatment. Endocrinologists can approach medical therapy with a goal of establishing normal cortisol levels or reducing cortisol levels to very low levels and replacing to achieve desired levels.

Remission in Cushing’s syndrome is associated with notable improvement; however, long-term follow-up is recommended for osteoporosis, CVD and psychiatric conditions.

After treatment, patients may experience reductions in weight, blood pressure, lipids and glucose levels that may allow reduction or discontinuation of medications. Even so, patients with a history of Cushing’s syndrome tend to have higher rates of hypertension, hyperlipidemia and diabetes. Likewise, rates of myocardial infarction are higher in this population, further emphasizing the need for treatment and management of diabetes and hypertension.

Sharpless highlighted that Cushing’s syndrome is rare.

“There are multiple studies that have shown that patients do better when they are treated in a specialty center where people see a lot of cases of this. So in that sense, treatment is not usually going to fall to the general practitioner,” she said.

She continued that the guidelines are helpful and provide guidance to endocrinologist who “can’t readily refer their patient to a pituitary center.”

Sharpless went on to describe the multidisciplinary care involved in Cushing’s syndrome including endocrinologists, neurosurgeons, radiologists, counselors and radiation oncologist.

“When the care is complicated, you want to ensure all of your providers have reviewed your case together and figured out the best plan.”

The guidelines were co-sponsored by the European Society of Endocrinology. Nieman received salary support for her work on the manuscript from the Intramural Research Program of the Eunice Kennedy Shiver Institute of Child Health and Human Development. Members of the task force reported multiple disclosures.

Does a Normal Urine Free Cortisol Result Rule out Cushing’s Syndrome?

Posted on August 4, 2015 by MaryO
Endocrine Society’s 97th Annual Meeting and Expo, March 5–8, 2015 – San Diego
SAT-384:
Does a Normal Urine Free Cortisol Result Rule out Cushing’s Syndrome?
Susmeeta T. Sharma1 and Lynnette K Nieman2

  • 1Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD
  • 2National Institutes of Health, Bethesda, MD
Presentation Number: SAT-384
Date of Presentation: March 7, 2015
Abstract:Background: Urine free cortisol (UFC) has been traditionally used as one of the first steps in the diagnostic evaluation of Cushing’s syndrome (CS) (1). False positive results, especially values less than twice the upper limit of normal (ULN), can be seen in uncontrolled diabetes, obesity, depression, alcoholism, increased fluid intake, overcollection and stress. False negative results have also been reported with incomplete collection, in mild or cyclic CS and in patients with renal insufficiency (2-3). We evaluated the diagnostic accuracy of UFC and 24-hour urine 17-hydroxycorticosteroids (17OHCS) in patients with CS.Methods: Retrospective study of all CS patients evaluated at the National Institutes of Health (NIH) from 2009 to 2014. Screening tests used for CS included UFC, 17OHCS, late night salivary cortisol (LNSC), midnight serum cortisol and low dose (1mg overnight or 2-day 2mg/day) dexamethasone suppression test (DST). Values above reference range for UFC, 17OHCS and LNSC, a midnight serum cortisol ≥ 7.5 mcg/dL, and post-dexamethasone cortisol values ≥ 1.8 mcg/dL were considered abnormal. Hourly 24-hour sampling for cortisol was performed in a few cases with a mild clinical phenotype and equivocal test results. UFC was measured using liquid chromatography/tandem mass spectrometry (LC-MS/MS). 17OHCS was measured using colorimetric methodology with Porter-Silber reaction (reported as mg/g of creatinine). Mean of the first two UFC and 17OHCS values (appropriate collection by urine volume and creatinine) obtained within 30 days of initial NIH presentation were used for the purpose of this study.

Results: Seventy-two patients were diagnosed with CS (aged 18-77 years, 51 females). Of these, 51 had Cushing’s disease (CD), 10 had ectopic CS while 2 had an adrenal source of Cushing’s based on pathology. Biochemical tests including inferior petrosal sinus sampling (IPSS) suggested ectopic CS but no tumor was found (occult) in 6 patients. IPSS was indicative of a pituitary source in 2 patients with failed transsphenoidal surgery while one patient did not complete evaluation for ACTH-dependent CS. UFC results were available in all, 17OHCS in 70, LNSC in 21, midnight serum cortisol in 68 and DST results in 37 patients. UFC was falsely normal in six and only minimally elevated (< 2 x ULN) in 13 patients (normal renal function, no history of cyclicity, all had CD). Of these 19 patients, 24h 17OHCS was abnormal in all, LNSC was abnormal in 12, midnight serum cortisol was abnormal in 18 and DST was abnormal in 12 patients. Hourly 24-hour sampling for cortisol performed in 3 of these patients revealed abnormal nadir (> 7.5 mcg/dL) and mean daily serum cortisol (> 9 mcg/dL) levels.

Conclusion: UFC can be falsely normal or only minimally elevated in mild CS. Multiple collections and use of complimentary screening tests including 24-hour urine 17OHCS and LNSC can help make a diagnosis and prevent delay in treatment.
