The Cushings Disease Treatment Market To Be Consistent In The Next 10 Years

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.

Metastatic Pituitary Carcinoma Successfully Treated with Radiation, Chemo.

A man with Cushing’s disease — caused by an adrenocorticotrophic hormone (ACTH)-secreting pituitary adenoma — who later developed metastases in the central nervous system without Cushing’s recurrence, was successfully treated over eight years with radiation and chemotherapy, according to a case report.

The report, “Long-term survival following transformation of an adrenocorticotropic hormone secreting pituitary macroadenoma to a silent corticotroph pituitary carcinoma: Case report,” was published in the journal World Neurosurgery.

Pituitary carcinomas make up only 0.1-0.2% of all pituitary tumors and are characterized by a primary pituitary tumor that metastasizes into cranial, spinal, or systemic locations. Fewer than 200 cases have been reported in the literature.

Most of these carcinomas secrete hormones, with ACTH being the most common. Though the majority of ACTH-secreting carcinomas present with Cushing’s disease, about one-third do not show symptoms of the condition and have normal serum cortisol and ACTH levels. These are called silent corticotroph adenomas and are considered more aggressive.

A research team at the University of Alabama at Birmingham presented the case of a 51-year-old Caucasian man with ACTH-dependent Cushing’s disease. He had undergone an incomplete transsphenoidal (through the nose) resection of an ACTH-secreting pituitary macroadenoma – larger than 10 mm in size – and radiation therapy the year before.

At referral in August 1997, the patient had persistent high cortisol levels and partial hypopituitarism, or pituitary insufficiency. He exhibited Cushing’s symptoms, including facial reddening, moon facies, weight gain above the collarbone, “buffalo hump,” and abdominal stretch marks.

About two years later, the man was weaned off ketoconazole — a medication used to lower cortisol levels — and his cortisol levels had been effectively reduced. He also had no physical manifestations of Cushing’s apart from facial reddening.

In May 2010, the patient reported two episodes of partial seizures, describing two spells of right arm tingling, followed by impaired peripheral vision. Imaging showed a 2.1-by-1-cm mass with an associated cyst within the brain’s right posterior temporal lobe, as well as a 1.8-by-1.2-cm mass at the cervicomedullary junction, which is the region where the brainstem continues as the spinal cord. His right temporal cystic mass was then removed by craniotomy.

A histopathologic analysis was consistent with pituitary carcinoma. Cell morphology was generally similar to the primary pituitary tumor, but cell proliferation was higher. Physical exams showed no recurrence of Cushing’s disease and 24-hour free urinary cortisol was within the normal range.

His cervicomedullary metastasis was treated with radiation therapy in July 2010. He took the oral chemotherapy temozolomide until August 2011, and Avastin (bevacizumab, by Genentech) was administered from September 2010 to November 2012.

At present, the patient continues to undergo annual imaging and laboratory draws. He receives treatment with hydrocortisone, levothyroxine — synthetic thyroid hormone — and testosterone replacement with androgel.

His most recent exam showed no progression over eight years of a small residual right temporal cyst, a residual mass along the pituitary stalk — the connection between the hypothalamus and the pituitary gland — and a small residual mass at the cervicomedullary junction. Lab results continue to show no Cushing’s recurrence.

“Our case is the first to document a patient who initially presented with an endocrinologically active ACTH secreting pituitary adenoma and Cushing’s disease who later developed cranial and spinal metastases without recurrence of Cushing’s disease and transformation to a silent corticotroph pituitary carcinoma,” the scientists wrote.

They added that the report is also the first documenting “8 years of progression-free survival in a patient with pituitary carcinoma treated with radiotherapy, [temozolomide] and bevacizumab.”

Fluconazole Found to Be Safe Alternative for Patient with Recurrent Cushing’s

Treatment with fluconazole after cabergoline eased symptoms and normalized cortisol levels in a patient with recurrent Cushing’s disease who failed to respond to ketoconazole, a case study reports.

The case report, “Fluconazole as a Safe and Effective Alternative to Ketoconazole in Controlling Hypercortisolism of Recurrent Cushing’s Disease: A Case Report,” was published in the International Journal of Endocrinology Metabolism.

Ketoconazole, (brand name Nizoral, among others) is an anti-fungal treatment used off-label for Cushing’s disease to prevent excess cortisol production, a distinct symptom of the disease. However, severe side effects associated with its use often result in treatment discontinuation and have led to its unavailability or restriction in many countries.

Consequently, there is a need for alternative medications that help manage disease activity and clinical symptoms without causing adverse reactions, and that could be given to patients who do not respond to ketoconazole treatment.

In this case report, researchers in Malaysia reported on a 50-year-old woman who fared well with fluconazole treatment after experiencing severe side effects with ketoconazole.

The woman had been in remission for 16 years after a transsphenoidal surgery — a minimally invasive brain surgery to remove a pituitary tumor — but went to the clinic with a three-year history of high blood pressure and gradual weight gain.

She also showed classic symptoms of Cushing’s disease: moon face, fragile skin that bruised easily, and purple stretch marks on her thighs.

Blood and urine analysis confirmed high cortisol levels, consistent with a relapse of the pituitary tumor. Accordingly, magnetic resonance imaging (MRI) of her brain showed the presence of a small tumor on the right side of the pituitary gland, confirming the diagnosis of recurrent Cushing’s disease.

Doctors performed another transsphenoidal surgery to remove the tumor, and a brain MRI then confirmed the success of the surgery. However, her blood and urine cortisol levels remained markedly high, indicating persistent disease activity.

The patient refused radiation therapy or adrenal gland removal surgery, and was thus prescribed ketoconazole twice daily for managing the disease. But after one month on ketoconazole, she experienced low cortisol levels.

Hydrocortisone — a synthetic cortisol hormone — was administered to maintain steady cortisol levels. However, she developed severe skin itching and peeling, which are known side effects of ketoconazole. She also suffered a brain bleeding episode, for which she had to have a craniotomy to remove the blood clot.

Since she experienced adverse effects on ketoconazole, which also hadn’t decreased her disease activity, the doctors switched her to cabergoline. Cabergoline (marketed as Dostinex, among others) is a dopamine receptor agonist that has been shown to be effective in managing Cushing’s disease.

But cabergoline treatment also did not lower the disease activity, and her symptoms persisted.

The doctors then added fluconazole (marketed as Diflucan, among others), an anti-fungal medication, based on studies that showed promising results in managing Cushing’s syndrome. Three months after the addition of fluconazole to her treatment plan, the patient’s clinical symptoms and cortisol levels had responded favorably.

At her next clinical visit 15 months later, her condition remained stable with no adverse events.

“This case demonstrates the long-term efficacy of fluconazole in tandem with cabergoline for the control of recurrent Cushing’s disease,” the researchers wrote.

The favorable outcome in this case also “supports the notion that fluconazole is a viable substitute for ketoconazole in the medical management of this rare but serious condition,” they concluded.

Etomidate Found Effective in Severe Cushing’s Syndrome

Etomidate — a steroid synthesis blocker — is an effective treatment for patients with severe Cushing’s syndrome who do not respond to ketoconazole, according to a new case report from Mexico.

The report, “Etomidate in the control of severe Cushing’s syndrome by neuroendocrine carcinoma,” appeared in the journal Clinical Case Reports.

The investigators reported the case of a 51-year-old woman with ectopic Cushing’s syndrome caused by a pancreatic tumor. Ectopic Cushing’s refers to cases of excess secretion of adrenocorticotropin hormone (ACTH) outside the pituitary or adrenal glands.

The patient underwent distal pancreatectomy — the surgical removal of the bottom half of the pancreas — in 2015 due to an ACTH-secreting tumor. Although she had a good initial response, liver metastasis was evident by 2016.

Compared to measurements in 2016, morning blood cortisol, 24-hour urinary-free cortisol, and ACTH levels significantly increased in 2017. The patient also showed low levels of the luteinizing and follicle-stimulating hormones, which the scientists attributed to her severe hypercortisolism (excess cortisol levels).

The woman was being treated with ketoconazole to lower her cortisol values and later received chemoembolization — a method to reduce blood supply and deliver chemotherapy directly to a tumor — for her liver metastasis.

Although ketoconazole is generally the treatment of choice for the control of hormone production in the adrenal glands, its effectiveness is often limited and is associated with side effects, clinicians noted.

In April 2017, the patient arrived at the emergency room with sepsis — a potentially life-threatening complication of an infection — that originated in the gut.

Because ketoconazole had failed to lower cortisol levels, the patient started receiving infused etomidate, an inhibitor of the enzyme 11‐beta‐hydroxylase that prevents cortisol synthesis.

This treatment was stopped one day before the bilateral removal of the adrenal glands as a definitive treatment for the elevated production of cortisol.

While the patient experienced decreased levels of potassium, calcium, and magnesium with an initial dose of 0.04 mg per kg body weight an hour of etomidate, a gradual decrease of etomidate — depending on her cortisol levels — corrected these alterations.

After surgery, the patient showed a significant improvement in her general health, including control of her sepsis. She is currently taking hydrocortisone and fludrocortisone, with treatment for liver metastasis pending.

“Etomidate is a very effective drug in severe Cushing’s syndrome that is refractory to ketoconazole,” the researchers wrote.

“Control of the serum cortisol levels in ectopic Cushing’s syndrome can be obtained with infusion rates much lower than those used in anesthesia, without respiratory side effects,” they added.

The authors recommend an initial dose of etomidate of 0.04 mg/kg per hour, daily monitoring of 24-hour urinary cortisol and cortisol levels, and a gradual decrease of the etomidate dose according to daily measurements of metabolites.

Rare Malignant Tumor of Adrenal Gland Led to Cushing’s, Girl’s Death

While adrenocortical carcinoma — a malignant tumor of the adrenal gland — appears only rarely in children, the tumor may cause secondary Cushing’s syndrome in these patients, a new case report shows.

Early diagnosis of the causes of Cushing’s syndrome could improve the prognosis of these children, researchers say.

The study, “Cushing Syndrome Revealing an Adrenocortical Carcinoma,” was published in the Open Journal of Pediatrics.

Adrenocortical carcinoma is a malignant tumor that develops in the cortex of the adrenal gland. It usually is identified by increased amounts of hormones that are produced by the adrenal glands, like cortisol.

This tumor type is very rare in children, representing fewer than two in every 1,000 pediatric tumors.

Researchers at the University Hospital Center Souro Sanou, in Burquina Faso (West Africa), described the case of a 10-year-old girl who developed this rare cancer.

The patient’s first symptoms were loss of consciousness and recurrent seizures without fever. The patient also had experienced excessive weight gain in the preceding months. At admission she was in a light state of coma and showed obesity in the face and trunk.

An initial analysis of blood, urine, and cerebrospinal fluid failed to detect any alterations, with no diabetes, kidney damage, or infection identified. And, even though no lesions or alteration were seen in the pituitary gland region, brain swelling was detected.

While in the hospital, the patient’s condition continued to deteriorate. She developed fever and difficulty speaking, while showing persistent seizures.

In the absence of a diagnosis, physicians focused on the safeguard of major vital function, control of seizures, and administration of large-spectrum antibiotics. Her condition improved slightly, regaining consciousness and control of seizures.

One month later, however, the patient developed symptoms that are commonly associated with increased levels of cortisol and male sex hormones, including obesity and early development of pubic hair.

After confirming high cortisol levels, physicians examined the patient’s abdominal region,  which revealed a tumor in the left adrenal gland.

The patient received a ketoconazole treatment and a surgery to remove the tumor was planned. But her condition worsened, with development of malignant hypertension and convulsive illness, which led to her death before the tumor was removed.

“The delay in the diagnosis and the insufficiency of the therapeutic means darken the prognosis in our context,” the researchers wrote.

“[Adrenocortical carcinoma] diagnosis should be considered in presence of virilization and early signs of puberty,” the researchers suggested. “Early diagnosis and multidisciplinary management of adrenocortical carcinoma could improve the prognosis in children.”
