Exophthalmos and Cushing’s Syndrome

Posted on February 4, 2015 by MaryO

A woman experienced red, irritated and bulging eyes. She saw an ophthalmologist who strongly suspected Graves’ ophthalmopathy. However, the patient did not have and never had hyperthyroidism.

Indeed, she had primary hypothyroidism optimally treated with levothyroxine. Her thyroid stimulating hormone level was 1.197 uIU/mL.

An MRI of the orbits showed normal extraocular muscles without thickening, but there was mild proptosis and somewhat increased intraorbital fat content. Both thyroid-stimulating immunoglobulins as well as thyrotropin receptor antibodies were negative.

The patient presented to her primary care physician a few months later. She had experienced a 40-lb weight gain over only a few months and also had difficult-to-control blood pressure.

After failing to respond to several antihypertensive medications, her primary care physician astutely decided to evaluate for secondary causes of hypertension. A renal ultrasound was ordered to evaluate for renal artery stenosis, and the imaging identified an incidental right-sided adrenal mass. A CT confirmed a 3.4-cm right-sided adrenal mass. Her morning cortisol was slightly high at 24.7 ug/dL (4.3 – 22.4) and her adrenocorticotropic hormone was slightly low at 5 pg/mL (10-60).

At this point I saw the patient in consultation. She definitely had many of the expected clinical exam findings of Cushing’s syndrome, including increased fat deposition to her abdomen, neck, and supraclavicular areas, as well as striae. Her 24-hour urine cortisol was markedly elevated at 358 mcg/24hrs (< 45) confirming our suspicions.

She asked me, “Do you think that my eye problem could be related to this?”

“I’ve not heard of it before,” I replied, “but that doesn’t mean there can’t be a connection. Wouldn’t it be wonderful if your eyes got better after surgery?”

The patient underwent surgery to remove what fortunately turned out to be a benign adrenal adenoma.

When we saw her in follow-up 2 weeks later, her blood pressures were normal off medication and her eye symptoms had improved. I had a medical student rotating with me, so I suggested that we do a PubMed literature search.

The first article to come up was a case report titled “Exophthalmos: A Forgotten Clinical Sign of Cushing’s Syndrome.” Indeed, not only did Harvey Cushing describe this clinical finding in his original case series in 1932, but others have reported that up to 45% of patients with active Cushing’s syndrome have exophthalmos.

The cause is uncertain but is theorized to be due to increased intraorbital fat deposition. Unlike exophthalmos due to thyroid disease, the orbital muscles are relatively normal — just as they were with our patient.

Some of you may have seen exophthalmos in your Cushing’s patients; however, this was the first time I had seen it. Just because one has not heard of something, does not mean it could never happen; no one knows everything. “When in doubt, look it up” is a good habit for both attending physicians and their students.

Myth: It is MY fault that I got Cushing’s…

Posted on December 12, 2014 by MaryO

Myth: “It is MY fault that I got Cushing’s. I did something wrong that caused me to be sick! If I would have just done XYZ, this would not be happening to me!”

myth-busted

Fact: This is a very controversial topic because we don’t like to talk about it. However, many people struggle with this myth. We NEED to dispel this myth my friends! Patients themselves assume responsibility, accountability, and self blame for becoming ill.

To compound all of that, patients are often told by loved ones, family, and sometimes even their churches or other supports that there is something that THEY could be doing or haven’t done that has caused their declining health. “If you would just follow that raw food diet, then all of your symptoms would go away”, “Juicing is the answer! I told you to juice and you wouldn’t get those tumors!”, Sometimes, you are told that if you would just pray harder or have greater faith, then there is no way that you would be sick right now. And my absolute favorite, “you are just too obsessed with being sick and having Cushing’s!  Stop thinking that you have it and it will go away!”.

Now, don’t get me wrong, I find value in “positive thinking” and affirming health, wealth, and all kinds of great things. This helps build up strength and personally keeps me motivated, especially during the times that I feel like absolutely throwing in the towel and giving up!

However, I am NOT the reason and YOU are not the reason for this war with this dreadful disease. What many people don’t understand is how tenacious, brave, courageous, and INDOMITABLE you are! Cushing’s patients do not just get surgery and then everything is magically OK.

Many patients have to go through multiple surgeries, sometimes radiation, sometimes years of testing to find the ultimate source of the disease, even after having several organs messed with. Even after patients obtain their “cure”, they are faced with residual and lingering negative effects of the illness, other hormone dysregulation issues, and the anxiety and fear of a recurrence which is based in absolute reality.

There are people, like myself, who are in remission from Cushing’s, BUT we now have Addison’s Disease/Adrenal Insufficiency as a result of removing vital organs in order to save our lives from Cushing’s. So, are we to think that Adrenal Insufficiency is ALSO our faults every time we near death after an adrenal crisis?! NO! NO! NO!

This is NOT your fault! This is NOT your doing! STOP blaming yourself! The best you can do is to FIGHT! Take an empowered stance by saying “NO” to those who won’t listen. Say “NO” to those who project blame onto you and tell you that this is just a “fat person’s excuse to stay fat”. You are not just a “fat person”! YOU are an amazing person who is fighting for your life!

Let me be clear that this blaming is common and we all do it. In my “5 stages of Loss” series on Youtube; I address the “Bargaining” stage of loss, in which we assume responsibility for getting sick or even for getting better.

Everyone should watch this to understand why and how we do this:

Remember, you are a survivor! YOU are Indomitable!!! This is NOT your fault! You WILL overcome!

Research Study: An Open Label Study to Assess the Safety and Efficacy of COR-003 (2S, 4R-ketoconazole) in the Treatment of Endogenous Cushing’s Syndrome

Posted on November 14, 2014 by MaryO

Objectives:         

The purpose of this study is to test the effects of different doses of COR-003 on people with Cushing’s syndrome (CS) primarily by measuring the cortisol levels in urine and secondarily by measuring other health parameters such as blood pressure, weight, and liver function. This study is also being conducted to see if there is any harm caused when using COR-003.

This study is an open label study. That means both the health providers and the participants in the study are aware of the drug or treatment being given.

Eligibility:

Adult Subjects (18 years or older) with elevated levels of cortisol due to endogenous CS.

Confirmed diagnosis of persistent or recurrent CS (with or without therapy) or newly diagnosed disease, if subjects are not candidates for surgery. CS will be defined according to the criteria in the guidelines for diagnosis of CS (Nieman 2008).

Women who are pregnant or lactating are not eligible for this study.

Individuals with other health conditions or diagnoses may not be eligible for this study.

These and other eligibility criteria are best reviewed with a doctor who is participating in the study. You can also get more detailed eligibility information about the study by clicking here to visit http://www.clinicaltrials.gov.

Study Design:

  • The study will begin with a screening period to make sure subjects are eligible to participate in the study.
  • After the screening period, subjects who are eligible for participation will each be given several different doses of COR-003, to be taken orally in tablet form.
  • After an individualized dose has been selected, participants will take COR-003 for six months.
  • Finally, participants will continue in the study for an additional six months at doses to be determined by the study doctor.

 

Throughout the study, participants will meet regularly with a study doctor and will take part in a variety of medical tests to make sure they are doing well and to see if COR-003 is working.

Participants in the study should be sure they have the time to participate. Participants will generally be followed for over a year:

Study Locations

The study is currently taking place in several places around the world (United States, Belgium, France, Israel, Netherlands, Spain, and Sweden).
Additional information on the study can be found at clinicaltrials.gov through this link.

EU Looks to Okay Ketoconazole for Use in Cushing’s Syndrome

Posted on September 27, 2014 by MaryO

The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended granting a marketing authorization for ketoconazole (Ketoconazole HRA; Laboratoire HRA Pharma) for the treatment of Cushing’s syndrome, a rare hormonal disorder sometimes called hypercortisolism.

Cushing’s syndrome is characterized by an excess of the hormone cortisol in the blood, which may be caused by a tumor. Treatment options currently available in the European Union include surgery to remove the tumor responsible for the high cortisol levels and radiotherapy, as well as several medicines that reduce the production of cortisol.

But pharmacological options remain very limited, and there is an unmet medical need for additional treatments, especially when surgery fails or for patients who cannot undergo surgery or take other medications. For this reason, the EMA’s CHMP evaluated the medicine under expedited review.

The opinion adopted by the CHMP at its September 2014 meeting is an intermediary step on Ketoconazole HRA’s path to patient access.

The CHMP opinion will now be sent to the European Commission for the adoption of a decision on an EU-wide marketing authorization. Once a marketing authorization has been granted, decisions about price and reimbursement will then take place at the level of each member state considering the potential role/use of this medicine in the context of the national health system of that country.

The recommendation is that Ketoconazole HRA is to be prescribed only by physicians specialized in treating Cushing’s syndrome, as the dosing needs to be individualized for each patient.

This is because oral ketoconazole was previously suspended in the European Union for the indication it was first approved for, fungal infections, due to risk for liver injury. The US Food and Drug Administration (FDA) also decreed, at the same time, that doctors should no longer prescribe ketoconazole tablets as a first-line therapy for any fungal infection, for the same reason.

Information will be sent to healthcare professionals to allow them to advise patients and prescribe the medicine safely and effectively.

A Medicine Used Off-Label for More than 30 Years

Doctors have used ketoconazole to treat Cushing’s syndrome for more than 30 years, although it has never been authorized for this indication in the European Union. The drug is also frequently used off-label in the United States and elsewhere for this purpose.

The CHMP’s recommendation builds on information from published literature and documented off-label use in clinical practice.

At the time of the suspension of ketoconazole for fungal infections, healthcare professionals and patients were concerned that ketoconazole would no longer be available for patients with Cushing’s syndrome.

The CHMP therefore reviewed Ketoconazole HRA through accelerated assessment to facilitate patients’ access to a fully authorized medicine as soon as possible with evidence-based information for patients and doctors.

When assessing Ketoconazole HRA for the treatment of Cushing’s syndrome, the CHMP considered that “in this rare and potentially life-threatening condition, the medicine’s benefits are greater than its risks, which can be manageable in clinical practice by specific measures mitigating the risk of liver toxicity, including close monitoring of the patients’ liver function.”

In 2012, it was estimated that the disease affected approximately 46,000 people in the European Union. Cushing’s syndrome is a long-lasting condition that can be life-threatening because of its complications, including diabetes, high blood pressure, and depression.

Long-term remission and recurrence rate in a cohort of Cushing’s disease: the need for long-term follow-up

 Abstract

OBJECTIVE:

Transsphenoidal surgery is the procedure of choice in Cushing disease (CD), with immediate post-operative remission rates ranging between 59 and 94 % and recurrence rates between 3 and 46 %, both depending upon the definition criteria and the duration of the follow-up. Our aim was to assess the rate of remission, recurrence and persistence of the disease after the first treatment and to identify predictors of remission in the CD population of our center.

METHODS:

Retrospective cohort study of the patients diagnosed of CD and with follow-up in our center between 1974 and 2011. We analyzed 41 patients (35 women and 6 men) with a mean age at diagnosis of 34 ± 13 years. The mean follow-up was 14 ± 10 years (range 1-37 years) and the median of follow-up period was 6.68 years.

RESULTS:

Thirty-five (85.4 %) patients underwent transsphenoidal surgery as first treatment option. Histopathological evidence of a pituitary adenoma was registered in 17 (48.5 %) patients. Thirty-two (78 %) patients achieved disease remission after the first treatment, 21 (65.6 %) of them presented disease recurrence. Persistent disease was observed in 9 (22 %) patients. Twelve (29.3 %) subjects developed post-surgical adrenal insufficiency, 7 of which (70 %) achieved stable remission. Two parameters were found to be significant predictors of remission after the first treatment: age at disease diagnosis and the development of adrenal insufficiency (cortisol ❤ μg/dl) in the immediate post-operative state.

CONCLUSIONS:

We report a high recurrence rate, at least partially attributable to the long follow-up time. Early post-surgery adrenal insufficiency predicts remission. Hypopituitarism was also very prevalent, and strongly associated with radiotherapy. These results lead us to the conclusion that CD needs a life-long strict follow-up.
