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

Posted on May 5, 2018 by MaryO

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.”

Cushing’s Patient Exhibits Cortisol-Secreting Lesions in Both Adrenal Glands

Posted on May 4, 2018 by MaryO

In rare cases, Cushing’s syndrome may be caused by cortisol-secreting masses in both adrenal glands, a case report shows.

The study with that finding, “ACTH-independent Cushing’s syndrome with bilateral cortisol-secreting adrenal adenomas: a case report and review of literatures” was published in BMC Endocrine Disorders.

Cushing’s syndrome results from the prolonged secretion of excess cortisol. While most cases are caused by tumors in the pituitary gland, up to 20 percent result from tumors in the adrenal glands.

Occasionally, Cushing’s syndrome is caused by masses in both adrenal glands, which may be similar or display different properties. “Determining the nature and function of bilateral adrenal masses is always a challenge in clinical practice,” researchers said.

Now, physicians at Sichuan University in China, reported the case of a 55-year-old woman who complained of difficulty breathing for more than 10 years.

The patient had developed obesity of the trunk and face over the past two years, and had been diagnosed with hypertension 10 years before. She also had high lipid levels for the past five years.

The patient was taking Avapro (irbesartan), Lopressor (metoprolol), Procardia XL (nifedipine), and statins for these disorders. No other health conditions or treatments were reported.

Physical examination showed a moon-shaped face, truncal obesity, and accumulation of fat in the back of the neck and upper back (aka buffalo hump). She also had discoloration of the lower limbs, with slight fluid accumulation and muscle weakness.

Routine blood analysis did not reveal significant changes, but hormone analysis showed high cortisol levels and low adrenocorticotropic hormone (ACTH) was low.

The amount of 24-hour urine-free cortisol was almost five times higher than the upper normal limit. Also, the patients had reduced response to corticosteroids treatment, showing even higher cortisol levels upon treatment with 1 mg dexamethasone. Additional evaluations revealed reduced bone mineral density, indicative of osteoporosis.

Together, the findings led to a diagnosis of ACTH-independent Cushing’s syndrome.

To identify what was causing Cushing’s syndrome, the team looked at the adrenal glands. They detected three lesions, one on the right side measuring 2.5 centimeters, and two on the left side, with 2.3 cm and 0.6 cm respectively. The masses in both sides were actively producing cortisol in similar proportions.

These results confirmed that the patient had Cushing’s syndrome induced by bilateral adrenal excessive cortisol secretion.

Because the patient had poor cardiac function, researchers planned a two-step operation. First, they removed the right adrenal gland laparoscopically, followed by the left adrenal gland two months later. The patient started replacement therapy with hydrocortisone, and her cortisol levels improved significantly, returning to normal levels. She also lost 4 kilograms (8.8 pounds) of body weight in the following year.

“The optimal treatment for patients with bilateral cortisol-secreting adenomas remains uncertain,” the researchers wrote. Although there are no reports of recurrence after surgical treatment, the long-term outcome of these patients remains unclear, and “lifelong follow-up of the patient is required,” they added.

Bilateral cortisol-secreting adrenal adenomas are rare, having been reported in only 15 other studies, the team wrote. Interestingly, some features reported in this study also were identified by other researchers, including the fact that bilateral cortisol-secreting adrenal lesions are more predominantly found in females during adulthood. Also, the size of the lesions commonly range between 1 to 5 centimeters when detected, and appear at approximately the same time in both adrenal glands.

Although there are no treatment guidelines for these cases, surgical removal of the lesions or adrenal glands, plus glucocorticoid replacement therapy, is the mostly used therapeutic approach. Importantly, the researchers noted that patients who underwent partial gland removal were able to withdraw from glucocorticoid replacement therapy during follow-up.

Mild Cortisol Increases Affect Cardiovascular Changes Linked to Heart Disease in Cushing’s

Posted on March 14, 2018 by MaryO

Increases in cortisol secretion, even if mild, induce early heart and blood vessel changes that may increase the risk for cardiovascular disease, according to Italian researchers.

The findings continue to support the role of the hormone cortisol in heart disease, and demonstrate the need for carefully monitoring cardiovascular risk in patients with high levels of the hormone, including those with Cushing’s disease.

The study, “Cardiovascular features of possible autonomous cortisol secretion in patients with adrenal incidentalomas,” was published in the European Journal of Endocrinology.

While most patients with adrenal incidentalomas don’t have symptoms, nearly half have excess cortisol production. Adrenal incidentalomas are masses in the adrenal glands discovered only when a patient undergoes imaging tests for another unrelated condition.

These asymptomatic, mild cortisol-producing cases are defined as possible autonomous cortisol secretion (pACS), according to the European Society of Endocrinology Guidelines.

Excess production of the hormone, seen in Cushing’s disease patients, is associated with increased mortality, mainly due to heart diseases. Patients with asymptomatic adrenal adenomas and mild cortisol secretion also have more cardiovascular events and generally die sooner than those with normal cortisol levels.

But little is known about the causes behind cardiac and vessel damage in these patients.

To shed light on this matter, a research team at Sapienza University of Rome evaluated the cardiovascular status of patients with pACS. This allowed them to study the impact of cortisol in the heart and blood vessels without the interference of other hormone and metabolic imbalances seen in Cushing’s disease.

The ERGO trial (NCT02611258) included 71 patients. All had been diagnosed with adrenal incidentalomas, 34 of which were pACS with mildly increased levels of the hormone and 37 were defined as nonfunctioning adenoma (NFA) — adrenal masses with normal hormone levels.

The two groups were very similar, with no significant differences in metabolic and cardiovascular risk factors. Adrenal lesions in the pACS group, however, were significantly bigger, which was linked to cortisol levels.

Looking at the heart morphology, researchers found that pACS patients had a significantly higher left ventricular mass index (LVMI), which is a well-established predictive measure of adverse cardiovascular events.

Further analysis revealed that LVMI scores were associated with levels of the hormone, suggesting it has an “independent effect of cortisol on cardiac function,” the researchers wrote.

Slightly more than half of pACS patients (53%) also had a thicker left ventricle, a feature that was seen only in 13.5% of NFA patients. The performance of the left ventricle during diastole (muscle relaxation) was also affected in 82.3% of pACS patients, compared to 35.1% in those with NFA.

Patients with pACS also had less flexible arteries, which may contribute to the development of vascular diseases.

The results show that “mild autonomous cortisol secretion can sustain early cardiac and vascular remodeling” in patients who appear apparently healthy, the researchers said.

“The morphological and functional cardiovascular changes observed in pACS underline the need for further studies to correctly define the long-term management of this relatively common condition,” they added.

Steroid Medication for Nasal Obstruction in Infants May Cause Cushing’s Syndrome

Posted on March 10, 2018 by MaryO

Intranasal steroid drops used to treat nasal obstruction may cause Cushing’s syndrome and adrenal insufficiency in infants, a case study of two patients suggests.

The study, “Iatrogenic Cushing’s syndrome and adrenal insufficiency in infants on intranasal dexamethasone drops for nasal obstruction – Case series and literature review,” was published in the International Journal of Pediatric Otorhinolaryngology.

Children with nasal obstruction may have severe delays in development and can face life-threatening complications later in life such as obstructive sleep apnea and cardiopulmonary problems.

While intranasal steroid drops have become increasingly popular as a substitute for surgery, they can have adverse effects. In addition to suppressing the immune system and changing metabolism, high levels of corticosteroids in the blood may cause Cushing’s syndrome.

Researchers at Weill Cornell Medical College presented two cases of adrenal gland insufficiency and Cushing’s syndrome caused by intranasal dexamethasone drops. Dexamethasone is a type of corticosteroid medication.

First, they described the case of a 3-month-old boy who was taken to the hospital following a life-threatening episode at home after feeding. A physical evaluation revealed nasal congestion with no additional anatomic abnormalities.

Treatment with nasal dexamethasone drops three times a day improved his breathing. While the dosage was later decreased to three drops once daily, a congestion episode led the mother to increase the dose back to the initial recommendation.

After seven weeks of treatment, the boy was noted to have facial puffiness, leading to an endocrine evaluation that revealed low cortisol levels. The dose was eventually reduced, and the boy’s cortisol levels returned to normal after several months.

The second case was a 6-week-old boy with a history of chronic congestion and difficulty feeding. He had severe nasal obstruction and required intubation due to respiratory distress. A nasal exam revealed damaged mucosa with severe nasal cavity narrowing, and he began treatment with three ciprofloxacin-dexamethasone drops three times a day.

After two and a half weeks of treatment, the boy’s cortisol levels were considerably low, and adrenal insufficiency was diagnosed. The treatment dose was reduced in an attempt to improve cortisol levels, but nasal obstruction symptoms continued.

The child then underwent surgery to resolve his nasal obstruction, and the treatment with steroid drops was discontinued. While his cortisol levels subsequently improved, they continued to be low, suggesting that he may have a hormone-related disease.

Despite the benefits of steroid-based nasal drops, small infants are more sensitive to steroid compounds. In addition, nasal drops are more easily absorbed than nasal sprays, suggesting that infants taking these medications should be better controlled for side effects.

“Patients started on this therapy must be closely monitored in a multi-disciplinary fashion to ensure patient safety and optimal symptom resolution,” the researchers suggested.

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

Posted on March 9, 2018 by MaryO

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.”
