Adrenal Gland Lump Led to 5-year-old Developing Cushing’s, Starting Puberty

Posted on February 17, 2018 by MaryO

Non-cancerous adrenal gland tumors can lead to rare cases of Cushing’s syndrome in young children and puberty starting years before it should, a case study of a 5-year-old boy shows.

Removing his right adrenal gland eliminated the problems, the Saudi Arabian researchers said.

Their report dealt with tumors in epithelial cells, which line the surface of many of the body’s structures and cavities.

The research, “Testosterone- and Cortisol-secreting Oncocytic Adrenocortical Adenoma in the Pediatric Age-group,” appeared in the journal Pediatric and Developmental Pathology.

Most tumors in adrenal gland epithelial cells are benign and generate normal levels of hormones. But there are cases when the tumors over-produce steroids and other kinds of hormones, including sex hormones. Sometimes the over-production can lead to Cushing’s syndrome.

The 5-year-old boy’s over-production of adrenal gland hormones led to both symptoms of Cushing’s syndrome and signs that he was starting puberty, the researchers said.

One reason the case was rare is that the average age when Cushing’s develops is 40, doctors say. Another is that epithelial adrenal gland tumors account for only 0.2 percent of all tumors in children, the researchers said.

Signs that the boy was starting puberty began appearing eight months before his parents took him for treatment. Doctors discovered he had the weight gain and rounded face associated with Cushing’s, but a battery of tests detected no other problems. No family members were experiencing the symptoms he was, doctors added.

Biochemical tests showed that the boy had a high level of cortisol in his blood, which doctors were unable to lower with the corticosteroid suppression medication dexamethasone.

Physicians also discovered that the boy had elevated levels of the male hormone testosterone, the cortisol precursor 17-hydroxyprogestrone, the cortisol-releasing hormone adrenocorticotropin, and another male hormone that the adrenal gland produces — dehydroepiandrosterone sulfate

In contrast, doctors discovered a below-normal level of luteinising, a sex hormone that the pituitary gland generates.

Another unusual manifestation of the boy’s condition was that his bone growth was that of a child a year older than he.

Doctors discovered a non-cancerous tumor in his right adrenal gland that they decided to remove. When they did, they discovered no evidence of bleeding, tissue scarring or cell death.

They put the boy on a hydrocortisone supplement, which they reduced over time and finally ended.

Twenty-eight months after the surgery, the boy showed no signs of Cushing’s disease or early puberty. And his weight, cortisol and adrenocorticotropin hormone levels were normal.

“To the best of our knowledge, our patient represents the first male patient” with a benign epithelial-cell adrenal gland tumor “in the pediatric population, with clinical presentation of precocious [early] puberty and Cushing’s syndrome,” the researchers wrote.

“As these tumors are exceptionally rare, reporting of additional cases and investigation of clinicopathological [disease] data are needed for better characterization of these tumors,” they wrote.

Patient’s Atypical Cushing’s Symptoms Lead to Discovery of Novel Genetic Mutations

Posted on February 14, 2018 by MaryO

New genetic mutations were found in a patient who exhibited atypical symptoms of Cushing’s syndrome, notably an abnormal protrusion of the eye, a case report shows.

The research, “Extensive ARMC5 genetic variance in primary bilateral macronodular adrenal hyperplasia that started with exophthalmos: a case report,” was published in the Journal of Medical Case Reports.

Primary bilateral macronodular adrenal hyperplasia (PBMAH) is a disorder characterized by multiple lumps in the adrenal glands and excessive cortisol production. It is a rare cause of Cushing’s syndrome.

According to recent research, PBMAH is caused by mutations in the ARMC5 gene, which data suggest may act as a tumor suppressor.

Researchers presented the case of a 52-year-old Chinese woman who exhibited a protrusion of both eyes (exophtalmos), which was first thought to be Graves’ ophthalmopathy. An injection of triamcinolone acetonide, a corticosteroid, into the area behind the eye globe did not improve symptoms.

The patient later was diagnosed with diabetes, which was treated with insulin, and hypertension, treated with insulin and amlodipine. She also developed muscle weakness and bruised easily. She had no other relevant chronic illness or infectious disease, and did not smoke tobacco or drink alcohol.

Physical examination showed skin atrophy, moon face, buffalo hump (between the shoulders), and purplish abdominal striae (stretch marks), which researchers defined as a typical Cushingoid appearance. The patient also experienced elevated pressure inside the eye, and had edema, conjunctival congestion, and lid retraction. No liver, spleen, respiration, cardiac, abdominal, blood counts, urinary, sensory, or motor abnormalities were noted.

Biochemical evaluation showed elevated cortisol and reduced adrenocorticotropin (ACTH) levels. Administering  dexamethasone did not lower the level of cortisol. Abnormal responses of the hormone vasopressin also were detected.

A computed tomography (CT) scan of the adrenal glands showed bilateral multiple lobular masses, and an MRI of the eye orbits indicated bilateral exophthalmos with hypertrophy of the retro-orbital fat, which lines the orbit.

After PBMAH was diagnosed, the patient’s adrenal glands were removed. Pathological findings showed multiple, homogenous, golden-yellow-colored nodules on the glands.

The surgery successfully lowered the level of cortisol and increased that of ACTH. The patient began taking hydrocortisone and metformin for diabetes. After six months, her exophtlamos, blood glucose levels, and blood pressure had improved.

Genetic analysis revealed six specific ARMC5 mutations in five of the seven adrenal nodules analyzed. “All the mutations are novel and not found in available online databases,” the researchers wrote. The mutations may lead to resistance to cell death in the tumor cells, and cause an increase in the production of cortisol, they observed.

As a result of the ARMC5 mutations, gene expression (conversion of genetic information) of the messenger RNA (mRNA, which is converted from DNA in the first step of protein synthesis) was lower in the adrenal tumor samples, in comparison with normal adrenal cortex.

Overall, the study “highlights the importance of early recognition of atypical symptoms of Cushing’s syndrome such as exophthalmos, which would save the patient from harmful effects of excessive cortisol exposure,” the researchers said. Screening for ARMC5 mutations also would help improve diagnosis and genetic counseling, they said.

Preoperative medical treatment in Cushing’s syndrome.

Posted on February 14, 2018 by MaryO

European Journal of Endocrinology — | February 14, 2018

Valassi E, et al. – This study was performed to assess how frequently preoperative medical treatment (PMT) was given to Cushing’s syndrome (CS) patients across Europe and to investigate differences in preoperative characteristics of patients who receive PMT and those who undergo primary surgery. In addition, the physicians determined if PMT influenced the postoperative outcome in pituitary-dependent CS (PIT-CS). In contrast with adrenal-dependent CS (ADR-CS), CS from an ectopic source (ECT-CS) and PIT-CS exhibited greater likelihood of receiving PMT. Data reported more severe clinical features at the diagnosis and poorer quality of life in PIT-CS patients treated with PMT. The interpretation of immediate postoperative outcome could be confounded with PMT. They recommended follow-up to definitely evaluate surgical results.

Methods

  • A total of 1,143 CS patients entered into the ERCUSYN database from 57 centres in 26 countries.
  • During this study, 69% patients presented with PIT-CS, 25% adrenal-dependent CS (ADR-CS), 5% CS from an ectopic source (ECT-CS), and 1% were classified as having CS from other causes (OTH-CS).

Results

  • In this study, 20% of patients took PMT.
  • PMT was offered more frequently in ECT-CS and PIT-CS compared to ADR-CS (p < 0.001).
  • Ketoconazole (62%), metyrapone (16%), and a combination of both (12%) were the most commonly used drugs.
  • The median (interquartile range) duration of PMT was 109 (98) days.
  • More severe clinical features at diagnosis and poorer quality of life were noted in PIT-CS patients treated with PMT compared to those undergoing primary surgery (SX) (p < 0.05).
  • PIT-CS patients treated with PMT were more likely to have normal cortisol (p < 0.01) and a lower remission rate (p < 0.01) within 7 days of surgery.
  • Between SX and PMT groups, no differences in morbidity or remission rates were observed within 6 months of surgery.

Common Cushing’s Treatment, Somatostatin Analogs, May Sometimes Worsen Disease Course

Posted on December 30, 2017 by MaryO

Doctors often prescribe somatostatin analogs to manage the hormonal imbalance that characterizes Cushing’s syndrome. However, in rare situations these medicines have paradoxically made patients worse than better.

This recently happened with a 48-year-old Spanish woman whose Cushing’s syndrome was caused by an adrenal gland tumor that was producing excess adrenocorticotropic hormone (ACTH). Her case was recently reported in the study “Ectopic Cushing’s syndrome: Paradoxical effect of somatostatin analogs,” and published in the journal Endocrinología, Diabetes y Nutrición.

Cushing’s syndrome occurs when the body produces too much cortisol. This can happen for many reasons, including an oversupply of ACTH, the hormone responsible for cortisol production, due to a tumor in the pituitary gland.

But sometimes, tumors growing elsewhere can also produce ACTH. This feature, known as ectopic ACTH secretion (EAS), may also cause ACTH-dependent Cushing’s syndrome.

Two-thirds of EAS tumors are located in the thorax, and 8 to 15 percent are in the abdominal cavity. Only 5 percent of EAS tumors are located in the adrenal gland, and up to 15 percent of EAS tumors are never detected.

Doctors usually use cortisol synthesis inhibitors such as ketoconazole or Metopirone (metyrapone) to control EAS, due to their efficacy and safety profiles. But somatostatin analogs (SSAs) such as Somatuline (lanreotide) have also been used to treat these tumors. However, these drugs produce mixed results.

The woman in the case study, reported by researchers at the University Hospital Vall d’Hebron in Barcelona, Spain, had an EAS tumor on the adrenal gland. She experienced s life-threatening cortisol and ACTH increase after receiving high-dose Somatuline.

The patient had been recently diagnosed with hypertension, and complained of intense fatigue, muscular weakness, easy bruising and an absence of menstruation. Laboratory analysis revealed that she had triple the normal levels of free cortisol in the urine, elevated levels of plasma cortisol, and high ACTH levels. In addition, her cortisol levels remained unchanged after receiving dexamethasone. The patient was therefore diagnosed with ACTH-dependent Cushing syndrome.

To determine the origin of her high cortisol levels, the team conducted magnetic resonance imaging (MRI). They found no tumors on the most common places, including the pituitary gland, neck, thorax or abdomen. However, additional evaluation detected a small alteration on the left adrenal gland, suggesting that was the source of ectopic ACTH production.

The team initiated treatment with 120 mg of Somatuline, but a week later, her condition had worsened and become life-threatening. Doctors started Ketoconazole treatment immediately, three times daily. The affected adrenal gland was surgically removed, and tissue analysis confirmed the diagnosis. The patient’s clinical condition improved significantly over the follow-up period.

“We highlight the need to be aware of this rare presentation of EAS, and we remark the difficulties of EAS diagnosis and treatment,”  researchers wrote.

The team could not rule out the possibility that the patient’s clinical development was due to the natural course of the disease. However, they believe “she had a paradoxical response on the basis of her dramatical worsening just after the SSAs administration, associated to an important rise in ACTH and UFC levels.”

For that reason, researchers think a new version of SSAs, such as Signifor (pasireotide) — which has improved receptor affinity — could provide better therapeutic response.

Pregnant Women with Hypertension and Hypercortisolism May Have Cushing’s

Posted on December 27, 2017 by MaryO

Pregnant woman with hypertension and significant signs of hypercortisolism (high cortisol levels) may have Cushing’s disease, according to a new case report.

The report, titled “A Case of Cushing’s Syndrome in Pregnancy,” was published in the Iranian Journal of Medical Sciences.

While Cushing’s rarely occurs in women during pregnancy, high cortisol levels can lead to major complications for both the mother and the fetus, such as premature birth and high fetal mortality.

However, it can be difficult to diagnose pathological hypercortisolism in these women as the symptoms might resemble other diseases that commonly occur during pregnancy, such as preeclampsia (high blood pressure during pregnancy) and gestational diabetes.

Unfortunately, there are no effective long-term medical therapies for Cushing’s. The most definitive therapy is the surgical removal of the pituitary or adrenal adenoma, if that is the case of hypercortisolism.

The case report details that a 29-year old women in the 27th week of pregnancy presented to the Ghaem Hospital clinic in Mashhad, Iran, with edema, weakness, and hypertension. Her symptoms also included truncal obesity, moon face (her face had a rounded appearance), purple steria on her upper and lower limbs and abdomen, excessive edema, and wet skin.

At first, she was hospitalized for suspected preeclampsia, but the diagnosis was later excluded.

The patient’s hormonal profile showed high levels of 24-hour urine cortisol. There were also low levels of adrenocorticotropic hormone (ACTH), which results from a negative feedback due to excessive cortisol. However, plasma cortisol is generally elevated during pregnancy, and therefore may not be the best method for diagnosis.

An abdominal ultrasonography revealed a well-defined mass in the right adrenal gland.

While hospitalized, the patient experienced two crises of blood pressure, and while preeclampsia was ruled out, the physicians could find no more plausible explanation than eclampsia (the onset of seizures in a women with preeclampsia).

Since eclampsia was suspected, the physicians terminated the pregnancy at 28th week of gestation using misoprostol. The woman delivered a male infant weighing 1.94 pounds.

Two days after birth, the physicians conducted a computed tomography (CT) scan and again found a mass in the right adrenal gland.

As a result, the patient underwent a laparoscopic right adrenalectomy to remove the mass one week after giving birth. The patient’s blood pressure normalized and cortisol levels declined. Her condition remained stable after surgery.

“Cushing’s syndrome should be considered in hypertensive pregnant patients with remarkable signs of hypercortisolism,” the researchers concluded. “The best results would be achieved through a collaboration between obstetricians, endocrinologists, and surgeons.”
