Macroadenoma biochemical behavior in pediatric patients with Cushing’s disease differs from adult cases

Posted on May 15, 2015 by MaryO

Cushing’s disease in children is associated with similar biochemical measures whether the disease is due to macroadenomas or microadenomas, according to a presentation at the AACE 24th Annual Scientific & Clinical Congress.

This contrasts with the disease behavior in adults, in whom macrodenomas demonstrate less glucocorticoid suppression and adrenocorticotropic hormone (ACTH) response to laboratory tests than do microadenomas, according to researchers.

“Children with pituitary macroadenomas are more likely to have the classical response to Cushing’s disease functional testing as microadenomas,”Ricardo Correa, MD, a clinical and research endocrinology fellow at National Institutes of Health, told Endocrine Today.

Correa and colleagues conducted a retrospective review of patients with Cushing’s disease who were younger than 18 years when they were admitted to the NIH between 1997 and 2014. All Cushing’s diagnoses were confirmed by pathology.

Pituitary macroadenoma was identified in 13 patients (69% female) and microadenoma in 74 (58% female). The groups had similar mean age (14 years) and BMI (31.8 kg/m2 and 30.2 kg/m2 for macroadenoma and microadenoma, respectively). The macroadenoma group had a median (25% to 75%) 24-hour urine free cortisol of  263.60 mcg/24 hr (range 170.7-528) compared with 371.6 mcg/ 24 hr (range 244.2-625.3) in the microadenoma group (P = 0.47). Median 24-hr urinary 17-hydroxysteroid excretion in the macroadenoma group was 12.6 mg/24 hr (range 8.9-42.5) and 31.6 mg/24 hr (range 4.3-39.9) in the microadenoma group.

Mean morning serum cortisol was 38.9 ± 40.4 mcg/dL compared with  20.2 ± 15.8 mcg/dL in the macroademona and microadenoma groups, respectively (P = 0.16). Mean morning basal plasma ACTH was 106.3 ± 112.3 pg/mL compared with 49.9±44.3 pg/mL for the macroadenoma and microadenoma groups, respectively (P = 0.11), while ACTH responses to the ovine corticotropin-releasing hormone test revealed no statistically significant differences. Using the high dose dexamethasone suppression test, 58% (7/12) suppressed more than 69% in the macroadenoma group compared to 69% (44/64) in the microadenoma group (P = .51).

“Studies in adult patients have demonstrated that macroadenomas have less glucocorticoid suppressibility after the high-dose dexamethasone suppression test and attenuated ACTH response to CRH compared to pituitary microadenomas,” according to Correa. “However, the present study shows that this is not true in children; although patients with macroadenomas had a tendency for higher baseline serum ACTH and cortisol levels, their responses to dynamic testing were similar to those with microadenomas.”

Day Twenty-seven, Cushing’s Awareness Challenge 2015

Posted on April 27, 2015 by MaryO

So often during the diagnosis phase of Cushing’s I felt like this picture – I was walking alone to an unknown place with an unknown future.

My diagnosis was pre-Internet which meant that any information had to be gotten from libraries, bookstores, magazines…or doctors.  In 1983 to 1986 I knew something was terribly wrong but there was no backup from doctors, family or friends.  My first hope was from a magazine (see Day Six)

After I got that first glimmer of hope, it was off to the library to try to understand medical texts.  I would pick out words I did understand – and it was more words each trip.  All my research led me to Cushing’s.

Unfortunately, the research didn’t lead me to doctors who could help for several years.  That contributed greatly to the loneliness.  If a Doctor says you’re not sick, friends and family are going to believe the doctor, not you.  After all, he’s the one trained to know what’s wrong, or find out.

I was so grateful when I finally got into a clinical trial at NIH and was so nice not to be alone with this mystery illness.  I was also surprised to learn, awful as I felt, there were Cushies much worse off than I was.

I am so glad that the Internet is here now helping us all know that we’re not alone anymore.

 

 

We’re all in this together with help, support, research, just being there.  I love this quote from Catherine at http://wheniwasyou.wordpress.com/2012/03/31/wheniwasyou/

Mary, I am delighted to see you here. Cushings – because of the persistent central obesity caused by (we know now) the lack of growth hormone plus the hypothyroidism I was diagnosed with (but for which treatment was ineffective due to my lack of cortisol) – was one of the things I considered as an explanation for my symptoms. Your site was enormously educational and helpful to me in figuring out what might be happening to me. Those other patient testimonies I referred to? Many of them were the bios you posted. Thank you so much for commenting. I am so grateful for the support and encouragement. I really hope that my experiences will help other undiagnosed hypopituitary patients find their way to a diagnosis. I often used to dream that one day I’d get to say to others what was so often said to me: don’t give up, there will be an answer. I kept believing in myself because people I hadn’t even met believed in me. Now I am finally here and I do hope my story will help others to have faith in their own instincts.

Thanks again. Please do keep in touch.

Catherine

Day Twenty-six, Cushing’s Awareness Challenge 2015

Posted on April 26, 2015 by MaryO

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 this is a semi-odd choice for 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-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, the tapes were long broken, but I had replaced all the songs – this time on my iPod.

Abide With Me was on this 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 Nineteen, Cushing’s Awareness Challenge 2015

Posted on April 19, 2015 by MaryO

 

Because it’s a Sunday again, this is a semi-religious post…

After I was finished with the Cushing’s long diagnostic process, surgery and several post-op visits to NIH, I was asked to give the scripture reading at my church. The man who preached the sermon that week was the survivor of a horrific accident where he and his family were hit by a van while waiting at an airport.

I thought I had written down the scripture reading carefully. I practiced and practiced. I don’t like speaking in front of a crowd but I said I would. When I got to church, the reading was different. Maybe I wrote it down wrong, maybe someone changed it. Whatever.

The real scripture turned out to be Psalm 116. I got very emotional while reading this and started crying when I got to verse 8 “For you, O LORD, have delivered my soul from death“.  Others in the congregation who knew part of my story were very moved, too.

psalm-116-1-4

Psalm 116 (New International Version)

1 I love the LORD, for he heard my voice;
he heard my cry for mercy.

2 Because he turned his ear to me,
I will call on him as long as I live.

3 The cords of death entangled me,
the anguish of the grave came upon me;
I was overcome by trouble and sorrow.

4 Then I called on the name of the LORD:
“O LORD, save me!”

5 The LORD is gracious and righteous;
our God is full of compassion.

6 The LORD protects the simplehearted;
when I was in great need, he saved me.

7 Be at rest once more, O my soul,
for the LORD has been good to you.

8 For you, O LORD, have delivered my soul from death,
my eyes from tears,
my feet from stumbling,

9 that I may walk before the LORD
in the land of the living.

10 I believed; therefore I said,
“I am greatly afflicted.”

11 And in my dismay I said,
“All men are liars.”

12 How can I repay the LORD
for all his goodness to me?

13 I will lift up the cup of salvation
and call on the name of the LORD.

14 I will fulfill my vows to the LORD
in the presence of all his people.

15 Precious in the sight of the LORD
is the death of his saints.

16 O LORD, truly I am your servant;
I am your servant, the son of your maidservant;
you have freed me from my chains.

17 I will sacrifice a thank offering to you
and call on the name of the LORD.

18 I will fulfill my vows to the LORD
in the presence of all his people,

19 in the courts of the house of the LORD—
in your midst, O Jerusalem.
Praise the LORD.

 

This Psalm has come to have so much meaning in my life. When I saw at a book called A Musician’s Book of Psalms each day had a different psalm. “My” psalm  was listed as the reading for my birthday, so I had to buy this book!  For a while, it was the license plate on my car.

I carry a print out of this everywhere I go because I find it very soothing. “when I was in great need, he saved me.” This print out is in a plastic page saver.

On the other side there is an article I found after my kidney cancer.  You can read that article in Day Twenty-five, coming up on April 25, 2015.  Plan Ahead!

Day Fifteen, Cushing’s Awareness Challenge 2015

Posted on April 15, 2015 by MaryO

Way back when we first got married, my husband thought we might have a lot of kids.  He was from a family of 6 siblings, so that’s what he was accustomed to.  I am on only child so I wasn’t sure about having so many.

I needn’t have worried.

In January, 1974 I had a miscarriage.  I was devastated. My father revealed that my mother had also had a miscarriage.  I had no idea.

At some point after this I tried fertility drugs.  Clomid and another drug.  One or both drugs made me very angry/depressed/bitchy (one dwarf I left off the image)  Little did I know that these meds were a waste of time.

Eventually,  I did get pregnant and my wonderful son, Michael was born.  It wasn’t until he was seven that I was finally, actually diagnosed with Cushing’s.

When I had my early Cushing’s symptoms, I thought I was pregnant again but it was not to be.

I’ll never forget the fall when he was in second grade.  He was leaving for school and I said good bye to him.  I knew I was going into NIH that day for at least 6 weeks and my future was very iffy.  The night before, I had signed my will – just in case.  He just turned and headed off with his friends…and I felt a little betrayed.

Michael wrote this paper on Cushing’s when he was in the 7th grade. From the quality of the pages, he typed this on typing paper – no computers yet!

Click on each page to enlarge.

When Michael started having headache issues in middle school, I had him tested for Cushing’s.  I had no idea yet if it could be familial but I wasn’t taking any chances.  It turned out that my father had also had some unnamed endocrine issues.  Hmmm…

I survived my time and surgery at NIH and Michael grew up to be a wonderful young man, if an only child.  🙂

After I survived kidney cancer (Day Twelve, Cushing’s Awareness Challenge 2015) Michael and I went zip-lining – a goal of mine after surviving that surgery.  This was taken in a treetop restaurant in Belize.

For the mathematically inclined, this is his blog.  Xor’s Hammer.  I understand none of it.  He also has a page of Math and Music, which I also don’t understand.
