Case Report Shows Rare Adrenal Tumors Associated with Cushing’s Disease

Pituitary tumors that produce too much adrenocorticotropic hormone (ACTH) have been associated with the development of rare tumors on the adrenal glands, called adrenal myelolipomas, for the first time in a case report.

The study, “Case report of a bilateral adrenal myelolipoma associated with Cushing disease,” was published in the journal Medicine.

Myelolipomas, composed of mature fat cells and blood-forming cells, are usually asymptomatic and do not produce hormones. In many cases, these tumors are detected by accident when patients undergo imaging scans for other conditions.

The cause of these tumors is unknown, but due to their benign nature, they do not spread to other parts of the body. However, they can grow up to 34 centimeters (about 13 inches), leading to tissue death and hemorrhage.

Researchers at Soon Chun Hyang University College of Medicine in Seoul, Korea, described the case of a 52-year-old man with myelolipoma possibly caused by an ACTH-secreting pituitary tumor.

During a routine checkup, researchers detected a mass in the patient’s spleen. Further abdominal evaluations identified tissue lesions in both adrenal glands consistent with myelolipoma. Besides the masses, the patient did not show any other Cushing-associated physical characteristics.

However, the patient’s ACTH levels were two times higher than the normal upper limit. Cortisol levels were also increased and unresponsive to low-dose dexamethasone treatment.

No additional lesions were found that could help explain the high ACTH and cortisol levels. But analysis of blood samples collected from the veins draining the pituitary glands revealed the right gland was producing too much ACTH, strongly suggesting Cushing’s disease.

Both the left adrenal gland and pituitary tumor were surgically removed. The samples collected during surgery confirmed the benign nature of the adrenal tumors, and the diagnosis of abnormal, ACTH-positive pituitary gland tissue.

Three days after the surgeries, hormone levels were back to normal. But a follow-up evaluation five months later again showed increased ACTH levels. Cortisol levels, however, were normal.

For the next seven years, the patient was evaluated every six months. During a five-year period, the size of the right adrenal gland was found to have grown. Imaging analysis confirmed the existence of small, new lesions in both pituitary glands.

“This case confers valuable information about the clinical course of adrenal myelolipoma associated with Cushing disease,” the researchers said. It also “supports the notion that ACTH can be associated with the development of bilateral adrenal myelolipomas.”


Crinetics Pharmaceuticals Awarded Two SBIR Grants to Develop New Therapeutics for Congenital Hyperinsulinism and Cushing’s Disease

SAN DIEGO, Sept. 06, 2017 (GLOBE NEWSWIRE) — Crinetics Pharmaceuticals, Inc., a rare disease therapeutics company focused on endocrine disorders and endocrine-related cancers, announced today that it was awarded two new grants from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the National Institutes of Health (NIH) that could total $2.4 million. Both are Small Business Innovation Research (SBIR) grants and include a Fast Track grant for up to $2.1 million and a Phase I grant of $0.3 million, which will be used for the development of Crinetics’ nonpeptide, oral somatostatin agonists for congenital hyperinsulinemia, and the discovery of novel small molecule drugs for Cushing’s disease, respectively.

“We are delighted with the NIH’s continuing support of our programs to develop new drugs for patients with rare endocrine disorders,” said Stephen Betz, Ph. D., Founder and Vice President of Biology of Crinetics. “These awards will enable us to advance our efforts in both hyperinsulinemia and Cushing’s disease, expanding our pipeline to include these diseases with significant unmet medical needs, and bring these treatments to the patients who need them.”

Presently, there are no medical therapies that were specifically developed to treat the life-threatening chronic hypoglycemia precipitated by congenital hyperinsulinism (CHI). The current options for patients are limited to drugs developed for other purposes in the hope that they might help. Despite their poor profiles, these drugs are prescribed because the next line of treatment is typically a partial or full pancreatectomy. Even when successful, patients who undergo the surgery often become diabetic and must actively manage glucose with multiple daily insulin injections for the rest of their lives.

Similarly, first line treatments for Cushing’s disease are surgical and involve removal of either the ACTH-secreting tumor in the pituitary or the adrenal glands themselves. As this is often unsuccessful, contraindicated or delayed, medical therapy for these patients becomes necessary. Current treatment options include inhibitors of steroid synthesis enzymes that can prevent the production of cortisol and improve symptoms, but these treatments also induce a host of unwanted side effects due to the accumulation of other steroid products.

About Congenital Hyperinsulinism (CHI)

Hyperinsulinemic hypoglycemia (HH) is one of the most frequent causes of persistent hypoglycemia in infants and can result in seizures, developmental delays, learning disabilities, and even death. The most severe form of HH is inherited and referred to as CHI. CHI largely results from mutations in key genes in the insulin secretion pathway in the islets of Langerhans in the pancreas.

About Cushing’s Disease

Clinical signs of Cushing’s syndrome include growth of fat pads (collarbone, back of neck, face and trunk), excessive sweating, dilation of capillaries, thinning of the skin, muscle weakness, hirsutism, depression/anxiety, hypertension, osteoporosis, insulin resistance, hyperglycemia, heart disease, and a range of other metabolic disturbances resulting in high morbidity. If inadequately controlled in its severe forms, Cushing’s syndrome is associated with high mortality. The most common form of Cushing’s syndrome is Cushing’s disease which is caused by microadenomas of pituitary corticotropic cells that secrete excess adrenocorticotropic hormone (ACTH).

Cushing’s Disease Treatment Market to Witness an Outstanding Growth by 2017 – 2025

Cushing disease is caused by tumour in the pituitary gland which leads to excessive secretion of a hormone called adrenocorticotrophic (ACTH), which in turn leads to increasing levels of cortisol in the body. Cortisol is a steroid hormone released by the adrenal glands and helps the body to deal with injury or infection. Increasing levels of cortisol increases the blood sugar and can even cause diabetes mellitus. However the disease is also caused due to excess production of hypothalamus corticotropin releasing hormone (CRH) which stimulates the synthesis of cortisol by the adrenal glands.

The condition is named after Harvey Cushing, the doctor who first identified the disease in 1912. Cushing disease results in Cushing syndrome. Cushing syndrome is a group of signs and symptoms developed due to prolonged exposure to cortisol.

Signs and symptoms of Cushing syndrome includes hypertension, abdominal obesity, muscle weakness, headache, fragile skin, acne, thin arms and legs, red stretch marks on stomach, fluid retention or swelling, excess body and facial hair, weight gain, acne, buffalo hump, tiredness, fatigue, brittle bones, low back pain, moon shaped face etc.

Symptoms vary from individual to individual depending upon the disease duration, age and gender of the patient.  Disease diagnosis is done by measuring levels of cortisol in patient’s urine, saliva or blood. For confirming the diagnosis, a blood test for ACTH is performed. The first-line treatment of the disease is through surgical resection of ACTH-secreting pituitary adenoma, however disease management is also done through medications, Cushing disease treatment market comprises of the drugs designed for lowering the level of cortisol in the body. Thus patients suffering from Cushing disease are prescribed medications such as ketoconazole, mitotane, aminoglutethimide metyrapone, mifepristone, etomidate and pasireotide.

8 Things You Should Know About Addison’s Disease



Cortisol gets a bad rap these days. (Guilty!) Yes, this hormone surges when you’re stressed. And yes, chronic stress is bad news for your health. But while too much cortisol can lead to all sorts of stress-related side effects, too little cortisol is equally debilitating.

Just ask someone with Addison’s disease. If you suffer from this condition, your adrenal glands fail to make adequate amounts of cortisol, says Betul Hatipoglu, MD, an endocrinologist at Cleveland Clinic.

Cortisol plays a role in regulating your blood pressure, heart function, digestion, and a lot else, Hatipoglu explains. So if your adrenal glands poop out and your cortisol levels plummet, a lot can go wrong. (In as little as 30 days, you can be a whole lot slimmer, way more energetic, and so much healthier just by following the simple, groundbreaking plan in The Thyroid Cure!)

Here’s what you need to know about this condition—starting with its craziest symptom.

It can make your teeth appear whiter.

Hatipoglu once met with a patient who was suffering from fatigue, belly pain, and mild weight loss. “Her doctors thought she was depressed,” Hatipoglu recalls. Toward the end of their appointment, Hatipoglu noticed the woman’s teeth looked very white. She realized they looked white because the woman’s skin was tan. “I asked her if she’d been on vacation, and she said she hadn’t been in the sun, and that’s when I knew,” Hatipoglu says. Some Addison’s-related hormone shifts can make the skin appear darker, almost like a tan. “Addison’s is the only disease I know of that can cause darkening of the skin,” she says.

Its (other) symptoms are popular ones.

 Along with darker skin, other symptoms of Addison’s include nausea, mild-to-severe abdominal or bone pain, weight loss, a lack of energy, forgetfulness, and low blood pressure, Hatipoglu says. Of course, those same symptoms are linked to many other health issues, from thyroid disease to cancer. “It’s very easy to confuse with other disorders, so many people see a lot of doctors before finally receiving a proper diagnosis,” she says. (One exception: For young women who develop Addison’s disease, loss of body hair is a warning sign, Hatipoglu adds.)
It’s rare.
Doctors also miss or misinterpret the symptoms of Addison’s disease because it’s very uncommon. “I’m not sure if it’s quite one in a million, but it’s very rare,” Hatipoglu says. “It makes sense that many doctors don’t think of it when examining a patient with these symptoms.”
It’s often confused with adrenal insufficiency.

A lot of online resources mention Addison’s disease and adrenal insufficiency as though they were two names for the same condition. They’re not the same, Hatipoglu says. While a thyroid issue or some other hormone-related imbalance could mess with your adrenal function, Addison’s disease refers to an autoimmune disorder in which your body attacks and destroys your adrenal glands.

That destruction can happen quickly.

While it takes months or even years for some Addison’s sufferers to lose all hormone production in their adrenal glands, for others the disease can knock out those organs very rapidly—in a matter of days, Hatipoglu says. “That’s very uncommon,” she adds. But compared to other less-severe adrenal issues, the symptoms of Addison’s tend to present more dramatically, she explains. That means a sufferer is likely to experience several of the symptoms mentioned above, and those symptoms will continue to grow worse as time passes.

Anybody can get it.

Addison’s is not picky. It can strike at any age, regardless of your sex or ethnicity, Hatipoglu says. While there’s some evidence that genetics may play a role—if other people in your family have the disease or some other endocrine disorder, that may increase your risk—there’s really no way to predict who will develop the disease, she adds.

Screening for Addison’s is pretty simple.

If your doctor suspects Addison’s, he or she will conduct a blood test to check for your levels of cortisol and another hormone called ACTH. “Usually the results of that screening are very clear,” Hatipoglu says. If they’re not, some follow-up tests can determine for sure if you have the condition.

There are effective treatments.

Those treatments involve taking oral hormone supplements.  In extreme cases, if the patient’s body does not properly absorb those supplements, injections may be necessary, Hatipoglu explains. “But patients live a normal life,” she adds. “It’s a treatable disease, and the treatments are effective.”


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)
