Day 12, Cushing’s Awareness Challenge

Posted on April 12, 2024 by MaryO

In March of 1987, after the endo finally  confirmed that I had Cushing’s, I was 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.

My first roommate was a nurse.  She spent the entire first night screaming in pain.  I was very glad when they moved me to a new room!

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 7, Cushing’s Awareness Challenge

Posted on April 7, 2024 by MaryO

sunday-glitter

It’s Sunday again, so this is another semi-religious post so feel free to skip it 🙂

I’m sure that many would think that Abide With Me is a pretty strange choice for my all-time favorite hymn.

My dad was a Congregational (now United Church of Christ) minister so I was pretty regular in church attendance in my younger years.

Some Sunday evenings, he would preach on a circuit and I’d go with him to some of these tiny churches.  The people there, mostly older folks, liked the old hymns best – Fanny Crosby and so on.

So, some of my “favorite hymns” are those that I sang when I was out with my Dad.  Fond memories from long ago.

In 1986 I was finally diagnosed with Cushing’s after struggling with doctors and trying to get them to test for about 5 years.  I was going to go into the NIH (National Institutes of Health) in Bethesda, MD for final testing and then-experimental pituitary surgery.

I was terrified and sure that I wouldn’t survive the surgery.

Somehow, I found a 3-cassette tape set of Readers Digest Hymns and Songs of Inspiration and ordered that. The set came just before I went to NIH and I had it with me.

At NIH I set up a daily “routine” of sorts and listening to these tapes was a very important part of my day and helped me get through the ordeal of more testing, surgery, post-op and more.

When I had my kidney cancer surgery, those tapes were long broken and irreplaceable, but I had replaced all the songs – this time on my iPod.

Abide With Me was on this original tape set and it remains a favorite to this day.  Whenever we have an opportunity in church to pick a favorite, my hand always shoots up and I request page 700.  When someone in one of my handbell groups moves away, we always sign a hymnbook and give it to them.  I sign page 700.

I think that many people would probably think that this hymn is depressing.  Maybe it is but to me it signifies times in my life when I thought I might die and I was so comforted by the sentiments here.

This hymn is often associated with funeral services and has given hope and comfort to so many over the years – me included.

If you abide in Me, and My words abide in you, you will ask what you desire, and it shall be done for you.

~John 15:7

Abide With Me

Words: Henry F. Lyte, 1847.

Music: Eventide, William H. Monk, 1861. Mrs. Monk described the setting:

This tune was written at a time of great sorrow—when together we watched, as we did daily, the glories of the setting sun. As the last golden ray faded, he took some paper and penciled that tune which has gone all over the earth.

Lyte was inspired to write this hymn as he was dying of tuberculosis; he finished it the Sunday he gave his farewell sermon in the parish he served so many years. The next day, he left for Italy to regain his health. He didn’t make it, though—he died in Nice, France, three weeks after writing these words. Here is an excerpt from his farewell sermon:

O brethren, I stand here among you today, as alive from the dead, if I may hope to impress it upon you, and induce you to prepare for that solemn hour which must come to all, by a timely acquaintance with the death of Christ.

For over a century, the bells of his church at All Saints in Lower Brixham, Devonshire, have rung out “Abide with Me” daily. The hymn was sung at the wedding of King George VI, at the wedding of his daughter, the future Queen Elizabeth II, and at the funeral of Nobel peace prize winner Mother Teresa of Calcutta in1997.

Abide with me; fast falls the eventide;

The darkness deepens; Lord with me abide.

When other helpers fail and comforts flee,

Help of the helpless, O abide with me.

Swift to its close ebbs out life’s little day;

Earth’s joys grow dim; its glories pass away;

Change and decay in all around I see;

O Thou who changest not, abide with me.

Not a brief glance I beg, a passing word;

But as Thou dwell’st with Thy disciples, Lord,

Familiar, condescending, patient, free.

Come not to sojourn, but abide with me.

Come not in terrors, as the King of kings,

But kind and good, with healing in Thy wings,

Tears for all woes, a heart for every plea—

Come, Friend of sinners, and thus bide with me.

Thou on my head in early youth didst smile;

And, though rebellious and perverse meanwhile,

Thou hast not left me, oft as I left Thee,

On to the close, O Lord, abide with me.

I need Thy presence every passing hour.

What but Thy grace can foil the tempter’s power?

Who, like Thyself, my guide and stay can be?

Through cloud and sunshine, Lord, abide with me.

I fear no foe, with Thee at hand to bless;

Ills have no weight, and tears no bitterness.

Where is death’s sting? Where, grave, thy victory?

I triumph still, if Thou abide with me.

Hold Thou Thy cross before my closing eyes;

Shine through the gloom and point me to the skies.

Heaven’s morning breaks, and earth’s vain shadows flee;

In life, in death, O Lord, abide with me.

Day 6: Cushing’s Awareness Challenge

Posted on April 6, 2024 by MaryO

cushings-diagnosis.gif?resize=515%2C356

The above is the official Cushing’s path to a diagnosis but here’s how it seems to be in real life:

Egads!  I remember the naive, simple days when I thought I’d give them a tube or two of blood and they’d tell me I had Cushing’s for sure.

Who knew that diagnosing Cushing’s would be years of testing, weeks of collecting every drop of urine, countless blood tests, many CT and MRI scans…

Then going to NIH, repeating all the above over 6 weeks inpatient plus an IPSS test, an apheresis (this was experimental at NIH) and specialty blood tests…

The path to a Cushing’s diagnosis is a long and arduous one but you have to stick with it if you believe you have this Syndrome.

Thyroid dysfunction highly prevalent in Cushing’s syndrome

Posted on February 9, 2021 by MaryO

Central hypothyroidism is prevalent in about 1 in 2 adults with Cushing’s syndrome, and thyroid function can be restored after curative surgery for most patients, according to study findings.

“Our study findings have confirmed and greatly extended previous smaller studies that suggested a link between hypercortisolism and thyroid dysfunction but were inconclusive due to smaller sample size and short follow-up,” Skand Shekhar, MD, an endocrinologist and clinical investigator in the reproductive physiology and pathophysiology group at the National Institute of Environmental Health Sciences, NIH, told Healio. “Due to our large sample and longer follow-up, we firmly established a significant negative correlation between hypercortisolemia measures — serum and urinary cortisol, serum adrenocorticotropic hormone — and thyroid hormones triiodothyronine, free thyroxine and thyrotropin.”

Shekhar and colleagues conducted a retrospective review of two groups of adults aged 18 to 60 years with Cushing’s syndrome. The first group was evaluated at the NIH Clinical Center from 2005 to 2018 (n = 68; mean age, 43.8 years; 62% white), and the second group was evaluated from 1985 to 1994 (n = 55; mean age, 37.2 years; 89% white). The first cohort was followed for 6 to 12 months to observe the pattern of thyroid hormone changes after surgical cure of adrenocorticotropic hormone-dependent Cushing’s syndrome. The second group underwent diurnal thyroid-stimulating hormone evaluation before treatment and during remission for some cases.

Urinary free cortisol and morning thyroid hormone levels were collected for all participants. In the second group, researchers evaluated diurnal patterns of TSH concentrations with hourly measurements from 3 to 7 p.m. and midnight to 4 p.m. In the first group, adrenocorticotropic hormone and serum cortisol were measured.

In the first cohort, seven participants were receiving levothyroxine for previously diagnosed primary or central hypothyroidism. Of the remaining 61 adults, 32 had untreated central hypothyroidism. Thirteen participants had free T4 at the lower limit of normal, and 19 had subnormal levels. There were 29 adults with subnormal levels of T3 and seven with subnormal TSH.

Before surgery, 36 participants in the first group had central hypothyroidism. Six months after surgery, central hypothyroidism remained for 10 participants. After 12 months, the number of adults with central hypothyroidism dropped to six. Preoperative T3 and TSH levels were negatively associated with morning and midnight cortisol, adrenocorticotropic hormone and urinary free cortisol. In post hoc analysis, a baseline urinary free cortisol of more than 1,000 g per day was adversely associated with baseline and 6-month T3 and free T4 levels.

In the second group, there were 51 participants not on thyroid-modifying drugs who had a thyroid function test 6 or 12 months after surgery. Before surgery, free T4 levels were subnormal in 17 participants, T3 levels were subnormal in 22, and TSH levels were in the lower half of the reference range or below in all but one participant.

After surgery, two participants had below normal free T4, one had subnormal T3, and TSH levels were in the lower half of the reference range or below in 23 of 48 participants. Before surgery, there was no difference in mean TSH between daytime and nighttime. A mean 8 months after surgery, the second group had a normal nocturnal TSH surge from 1.3 mIU/L during the day to 2.17 mIU/L at night (P = .01). The nocturnal TSH increase persisted as long as 3 years in participants who had follow-up evaluations.

“We found a very high prevalence of thyroid hormone deficiency that appears to start at the level of the hypothalamus-pituitary gland and extend to the tissue level,” Shekhar said. “Some of these patients may experience thyroid hormone deficiency symptoms, such as fatigue, depression, cold intolerance, weight gain, etc, as a result of systematic and tissue-level thyroid hormone deficiency. We also noted a strong correlation between hypothyroidism and hypogonadism, which implies that hypothyroid patients are also likely to suffer adverse reproductive effects. Thus, it is imperative to perform thorough thyroid hormone assessment in patients with Cushing’s syndrome, and thyroid hormone supplementation should be considered for these patients unless cure of Cushing’s syndrome is imminent.”

Researchers said providers should routinely screen for hypothyroidism in adults with Cushing’s syndrome. Even after thyroid function is restored, regular follow-up should also be conducted.

Further research is needed to investigate thyroid dysfunction in iatrogenic Cushing’s syndrome and the impact of these findings on euthyroid sick syndrome, Shekhar said.

Thyroid cancer: Cushing syndrome is a lesser-known warning sign – what is it?

Posted on February 1, 2021 by MaryO

Thyroid cancer survival rates are 84 percent for 10 years or more if diagnosed early. Early diagnosis is crucial therefore and spotting the unusual signs could be a matter of life and death. A sign your thyroid cancer has advanced includes Cushing syndrome.

What is it?

What is Cushing syndrome?

 

Cushing syndrome occurs when your body is exposed to high levels of the hormone cortisol for a long time, said the Mayo Clinic.

The health site continued: “Cushing syndrome, sometimes called hypercortisolism, may be caused by the use of oral corticosteroid medication.

“The condition can also occur when your body makes too much cortisol on its own.

“Too much cortisol can produce some of the hallmark signs of Cushing syndrome — a fatty hump between your shoulders, a rounded face, and pink or purple stretch marks on your skin.”

In a study published in the US National Library of Medicine National Institutes of Health, thyroid carcinoma and Cushing’s syndrome was further investigated.

The study noted: “Two cases of thyroid carcinoma and Cushing’s syndrome are reported.

“Both of our own cases were medullary carcinomas of the thyroid, and on reviewing the histology of five of the other cases all proved to be medullary carcinoma with identifiable amyloid in the stroma.

“A consideration of the temporal relationships of the development of the carcinoma and of Cushing’s syndrome suggested that in the two cases with papillary carcinoma these conditions could have been unrelated, but that in eight of the nine cases with medullary carcinoma there was evidence that thyroid carcinoma was present at the time of diagnosis of Cushing’s syndrome.

“Medullary carcinoma of the thyroid is also probably related to this group of tumours. It is suggested that the great majority of the tumours associated with Cushing’s syndrome are derived from cells of foregut origin which are endocrine in nature.”

In rare cases, adrenal tumours can cause Cushing syndrome a condition arising when a tumour secretes hormones the thyroid wouldn’t normally create.

Cushing syndrome associated with medullary thyroid cancer is uncommon.

The syndrome is more commonly caused by the pituitary gland overproducing adrenocorticotropic hormone (ACTH), or by taking oral corticosteroid medication.

See a GP if you have symptoms of thyroid cancer, warns the NHS.

The national health body added: “The symptoms may be caused by less serious conditions, such as an enlarged thyroid, so it’s important to get them checked.

“A GP will examine your neck and can organise a blood test to check how well your thyroid is working.

“If they think you could have cancer or they’re not sure what’s causing your symptoms, you’ll be referred to a hospital specialist for more tests.”
