Obesity is common at diagnosis of pituitary adenoma in childhood and may persist despite successful treatment, according to findings published in Clinical Endocrinology.

“The importance of childhood and adolescent obesity on noncommunicable disease in adult life is well recognized, and in this new cohort of patients, we report that obesity is common at presentation of pituitary adenoma in childhood and that successful treatment is not necessarily associated with weight loss,” Aashish Sethi, MD, MBBS, a pediatric endocrinologist in the department of endocrinology at Alder Hey Children’s Hospital in Liverpool, United Kingdom, and colleagues wrote. “We have reported obesity, and obesity-related morbidity in a mixed cohort of children and young adults previously, but [to] our knowledge, this is the first time this observation has been reported in a purely pediatric cohort.”

In a retrospective study, Sethi and colleagues analyzed clinical and radiological data from 24 white children from Alder Hey Children’s Hospital followed for a median of 3.3 years between 2000 and 2019 (17 girls; mean age at diagnosis, 15 years). Researchers assessed treatment modality (medical, surgical or radiation therapy), pituitary hormone deficiencies and BMI, as well as results of any genetic testing.

Within the cohort, 13 girls had prolactinomas (mean age, 15 years), including 10 macroadenomas between 11 mm and 35 mm in size. Children presented with menstrual disorders (91%), headache (46%), galactorrhea (46%) and obesity (38%). Nine children were treated with cabergoline alone, three also required surgery, and two were treated with the dopamine agonist cabergoline, surgery and radiotherapy.

Five children had Cushing’s disease (mean age, 14 years; two girls), including one macroadenoma. Those with Cushing’s disease presented with obesity (100%), short stature (60%) and headache (40%). Transsphenoidal resection resulted in biochemical cure; however, two patients experienced relapse 3 and 6 years after surgery, respectively, requiring radiotherapy. One patient also required bilateral adrenalectomy.

Six children had a nonfunctioning pituitary adenoma (mean age, 16 years; two girls), including two macroadenomas. These children presented with obesity (67%), visual field defects (50%) and headache (50%). Four required surgical resections, with two experiencing disease recurrence after surgery and requiring radiotherapy.

During the most recent follow-up exam, 13 children (54.1%) had obesity, including 11 who had obesity at diagnosis.

“The persistence of obesity following successful treatment, in patients with normal pituitary function, suggests that mechanisms other than pituitary hormone excess or deficiency may be important,” the researchers wrote. “It further signifies that obesity should be a part of active management in cases of pituitary adenoma from diagnosis.” – by Regina Schaffer

Iatrogenic Cushing’s Syndrome and the Hidden Ingredient of Artri King

Abstract

Cushing’s syndrome is a rare disorder caused by prolonged exposure to glucocorticoids, either from endogenous overproduction or exogenous sources, with exogenous steroid use being the most common etiology. Clinical manifestations may include moon facies, abdominal striae, easy bruising, muscle weakness, and complications such as osteoporosis and fragility fractures. Many remedies and supplements marketed for inflammatory conditions are sold online or over the counter, and some may contain hidden or undisclosed steroids that can lead to hypercortisolism. We present a case of a 52-year-old man with osteoporosis who sustained fragility fractures and became wheelchair-bound due to progressive lower extremity weakness. Evaluation demonstrated suppression of the hypothalamic-pituitary-adrenal axis, with undetectable salivary and urinary cortisol levels. Further investigation revealed long-term use of Artri King, a supplement for musculoskeletal pain that contains undisclosed glucocorticoids. This case highlights the risk of unregulated supplements causing iatrogenic Cushing’s syndrome and its associated complications.

Introduction

Cushing’s syndrome represents a constellation of signs and symptoms resulting from prolonged exposure to glucocorticoids [1]. Common manifestations may include moon facies, facial plethora, abdominal striae, easy bruising, and proximal muscle weakness [1]. Etiologies may be adrenocorticotropic hormone (ACTH)-dependent, originating from pituitary or ectopic sources, or ACTH-independent, such as adrenal pathology. In everyday clinical practice, however, exogenous glucocorticoid exposure remains the most common cause [2,3].

Exogenous steroids are available in multiple formulations, including oral, parenteral, inhaled, and topical preparations, and may be prescribed by healthcare providers or found in commercial products sold online or over the counter [4]. Prolonged exposure can result in hypercortisolism and its associated complications [5]. Therefore, careful assessment for exogenous steroid use is essential when evaluating patients with suspected Cushing’s syndrome. We report a case of iatrogenic Cushing’s syndrome secondary to the use of Artri King, a “herbal” supplement containing undisclosed glucocorticoids.

Case Presentation

A 52-year-old male with a history of prediabetes presented with osteoporosis and fragility fractures. Osteoporosis was diagnosed during imaging performed for the evaluation of back pain, which revealed thoracic spine compression fractures as well as a healed rib fracture. As a result, he became wheelchair-bound due to progressive lower extremity weakness. The patient denied prior trauma and had no family history of osteoporosis or pathologic fractures. He denied the use of steroids, proton pump inhibitors, anticoagulants, or antiseizure medications. He did not smoke and reported no alcohol use. There was no history of hypogonadism, bone disease, or fractures during childhood. Biochemical evaluation revealed a normal complete blood count, with pertinent laboratory results summarized in Table 1.

Laboratory test Value Units Reference range
Total testosterone 415 ng/dL 264–916
Intact parathyroid hormone 9.4 pg/mL 8.7–77.1
Corrected serum calcium 9.6 mg/dL 8.6–10.3
24-hour urine calcium 144 mg/24 hours 100–300*
Plasma adrenocorticotropic hormone Undetectable pg/mL 7–63*
Late-night salivary cortisol Undetectable µg/dL ≤0.09*
24-hour urine free cortisol Undetectable µg/24 hours 10–50*
Table 1: Biochemical laboratory results.

*: Reference intervals may vary by assay method and laboratory.

Given the presence of fragility fractures and physical examination findings consistent with Cushing’s syndrome, including moon facies, dorsocervical and supraclavicular fat fullness, and purplish striae (Figure 1), further evaluation was pursued. Laboratory testing demonstrated an undetectable serum ACTH level, and both late-night salivary cortisol and 24-hour urinary free cortisol levels were undetectable, raising concern for exogenous glucocorticoid exposure (Table 1). Dual-energy X-ray absorptiometry demonstrated a spinal bone mineral density of 0.686 g/cm² with a T-score of −3.7.

On further questioning, the patient reported taking Artri King for two years, obtained from Mexico, for joint pain and arthritis. A review of U.S. Food and Drug Administration (FDA) reports confirmed that Artri King contains hidden ingredients, including dexamethasone, not listed on its label. The supplement was discontinued, and the patient was started on a gradual steroid taper to minimize glucocorticoid withdrawal symptoms and allow for the recovery of hypothalamic-pituitary-adrenal (HPA) axis function.

Discussion

Cushing’s syndrome is a rare disorder characterized by a constellation of signs and symptoms affecting multiple organ systems as a result of prolonged exposure to excess cortisol. Hypercortisolism may result from endogenous overproduction of cortisol or from exposure to exogenous glucocorticoids [1]. Regardless of etiology, clinical manifestations commonly include moon facies, abdominal striae, truncal obesity, and easy bruising [1]. Patients with Cushing’s syndrome may also develop complications such as hyperglycemia, uncontrolled hypertension, proximal muscle weakness, and reduced BMD, which can lead to fragility fractures [2]. These complications significantly impair quality of life and may be fatal if the condition is not diagnosed and treated promptly [3].

Endogenous hypercortisolism is less common, with an estimated incidence of 2-3 cases per million per year [4]. However, recent studies suggest a higher prevalence among individuals with diabetes mellitus, osteoporosis, particularly those with fragility fractures, and hypertension [5]. Cushing’s syndrome can be classified as ACTH-dependent, in which ACTH originates from the pituitary gland or an ectopic source, or ACTH-independent, typically due to adrenal adenoma, adrenal hyperplasia, or adrenal carcinoma [5]. Although exogenous glucocorticoid exposure is the most common cause of Cushing’s syndrome, the true incidence of iatrogenic Cushing’s syndrome remains unknown [6]. Rarely, Cushing’s syndrome may result from concurrent exogenous steroid use and endogenous cortisol overproduction, which presents diagnostic challenges [6].

Glucocorticoid-containing medications are widely used in the management of inflammatory diseases, malignancies, and post-transplant care [7,8]. All forms of exogenous glucocorticoids, including oral, inhaled, injectable, and topical preparations, can cause features of hypercortisolism when used at high doses or for prolonged periods [9-12]. Extended exposure, particularly at higher doses, may also result in secondary adrenal insufficiency, even with topical formulations [13]. In addition to conventional glucocorticoids, other medications may induce iatrogenic hypercortisolism; for example, high-dose megestrol exhibits glucocorticoid-like activity and can produce Cushing’s syndrome-like features [14]. Furthermore, drugs that inhibit cytochrome P450 metabolism, such as itraconazole, can impair steroid clearance and increase systemic glucocorticoid exposure [15].

Of increasing concern is the availability of steroid-containing supplements sold over the counter or online without prescription [16]. These products are commonly marketed for conditions such as arthritis and other inflammatory disorders [16]. Prolonged use may cause Cushing’s syndrome with complications such as skin atrophy, obesity, myopathy, and fractures. The U.S. FDA has issued multiple warnings regarding dietary supplements and conventional foods found to contain undisclosed pharmaceutical ingredients [17]. A 2016 study evaluating 12 over-the-counter “adrenal support” supplements in the United States found that most contained at least one steroid hormone [18]. Another analysis of FDA warnings on unapproved pharmaceutical ingredients reported that 37.5% of products marketed for inflammatory conditions, including joint and muscle pain, contained dexamethasone [19]. Among these products, Artri King, marketed for joint pain and arthritis, has been associated with multiple FDA reports of adverse events due to undisclosed dexamethasone and methylprednisolone. These supplements remain widely available online, in select retail stores, and internationally [20].

Conclusions

This case highlights the importance of considering unregulated supplements as a potential source of exogenous glucocorticoids in patients presenting with osteoporosis and unexplained fragility fractures. Although the patient initially denied steroid use, detailed history revealed prolonged exposure to Artri King, resulting in iatrogenic Cushing’s syndrome with HPA axis suppression. Before discontinuation of steroid-containing supplements, evaluation for adrenal insufficiency is essential. Gradual tapering of glucocorticoids remains the standard approach to prevent withdrawal symptoms and support recovery of adrenal function.

Cushing’s Syndrome Treatments

Medications, Surgery, and Other Treatments for Cushing’s Syndrome

Written by | Reviewed by Daniel J. Toft MD, PhD

Treatment for Cushing’s syndrome depends on what symptoms you’re experiencing as well as the cause of Cushing’s syndrome.

Cushing’s syndrome is caused by an over-exposure to the hormone cortisol. This excessive hormone exposure can come from a tumor that’s over-producing either cortisol or adrenocorticotropic hormone (ACTH—which stimulates the body to make cortisol). It can also come from taking too many corticosteroid medications over a long period of time; corticosteroids mimic the effect of cortisol in the body.

The goal of treatment is to address the over-exposure. This article walks you through the most common treatments for Cushing’s syndrome.

Gradually decreasing corticosteroid medications: If your doctor has identified that the cause of your Cushing’s syndrome is corticosteroid medications, you may be able to manage your Cushing’s syndrome symptoms by reducing the overall amount of corticosteroids you take.

It’s common for some people with certain health conditions—such as arthritis and asthma—to take corticosteroids to help them manage their symptoms. In these cases, your doctor can prescribe non-corticosteroid medications, which will allow you to reduce—or eliminate—your use of corticosteroids.

It’s important to note that you shouldn’t stop taking corticosteroid medications on your own—suddenly stopping these medications could lead to a drop in cortisol levels—and you need a healthy amount of cortisol. When cortisol levels get too low, it can cause a variety of symptoms, such as muscle weakness, fatigue, weight loss, and low blood pressure, which may be life-threatening.

Instead, your doctor will gradually reduce your dose of corticosteroids to allow your body to resume normal production of cortisol.

If for some reason you cannot stop taking corticosteroids, your doctor will monitor your condition very carefully, frequently checking to make sure your blood glucose levels as well as your bone mass levels are normal. Elevated blood glucose levels and low bone density are signs of Cushing’s syndrome.

Surgery to remove a tumor: If it’s a tumor causing Cushing’s syndrome, your doctor may recommend surgery to remove the tumor. The 2 types of tumors that can cause Cushing’s are pituitary tumors (also called pituitary adenomas) and adrenal tumors. However, other tumors in the body (eg, in the lungs or pancreas) can cause Cushing’s syndrome, too.

Pituitary adenomas are benign (non-cancerous), and most adrenal tumors are as well. However, in rare cases, adrenal tumors can be malignant (cancerous). These tumors are called adrenocortical carcinomas, and it’s important to treat them right away.

Surgery for removing a pituitary tumor is a delicate process. It’s typically performed through the nostril, and your surgeon will use tiny specialized tools. The success, or cure, rate of this procedure is more than 80% when performed by a surgeon with extensive experience. If surgery fails or only produces a temporary cure, surgery can be repeated, often with good results.

If you have surgery to remove an adrenal tumor or tumor in your lungs or pancreas, your surgeon will typically remove it through a standard open surgery (through an incision in your stomach or back) or minimally invasive surgery in which small incisions are made and tiny tools are used.

In some cases of adrenal tumors, surgical removal of the adrenal glands may be necessary.

Radiation therapy for tumors: Sometimes your surgeon can’t remove the entire tumor. If that happens, he or she may recommend radiation therapy—a type of treatment that uses high-energy radiation to shrink tumors and/or destroy cancer cells.

Radiation therapy may also be prescribed if you’re not a candidate for surgery due to various reasons, such as location or size of the tumor. Radiation therapy for Cushing’s syndrome is typically given in small doses over a period of 6 weeks or by a technique called stereotactic radiosurgery or gamma-knife radiation.

Stereotactic radiosurgery is a more precise form of radiation. It targets the tumor without damaging healthy tissue.

With gamma-knife radiation, a large dose of radiation is sent to the tumor, and radiation exposure to the healthy surrounding tissues is minimized. Usually one treatment is needed with this type of radiation.

Medications for Cushing’s syndrome: If surgery and/or radiation aren’t effective, medications can be used to regulate cortisol production in the body. However, for people who have severe Cushing’s syndrome symptoms, sometimes medications are used before surgery and radiation treatment. This can help control excessive cortisol production and reduce risks during surgery.

Examples of medications your doctor may prescribe for Cushing’s syndrome are: aminoglutethimide (eg, Cytadren), ketoconazole (eg, Nizoral), metyrapone (eg, Metopirone), and mitotane (eg, Lysodren). Your doctor will let you know what medication—or combination of medications—is right for you.

You may also need to take medication after surgery to remove a pituitary tumor or adrenal tumor. Your doctor will most likely prescribe a cortisol replacement medication. This medication helps provide the proper amount of cortisol in your body. An example of this type of medication is hydrocortisone (a synthetic form of cortisol).

Experiencing the full effects of the medication can take up to a year or longer. But in most cases and under your doctor’s careful supervision, you can slowly reduce your use of cortisol replacement medications because your body will be able to produce normal cortisol levels again on its own. However, in some cases, people who have surgery to remove a tumor that causes Cushing’s syndrome won’t regain normal adrenal function, and they’ll typically need lifelong replacement therapy.2

Treating Cushing’s Syndrome Conclusion
You may need one treatment or a combination of these treatments to effectively treat your Cushing’s syndrome. Your doctor will let you know what treatments for Cushing’s syndrome you’ll need.

FDA Declines to Approve Relacorilant for Hypertension Linked to Hypercortisolism

Key takeaways:

  • The FDA issued a complete response letter for relacorilant to treat hypertension tied to hypercortisolism.
  • The investigational drug induced BP reductions for adults with hypertension in the phase 3 GRACE trial.

The FDA has issued a complete response letter for an oral selective glucocorticoid receptor antagonist under investigation for the treatment of hypertension secondary to hypercortisolism, according to an industry press release.

Corcept Therapeutics announced the FDA issued a complete response letter for relacorilant (Corcept Therapeutics). The drug is under investigation for the treatment of endogenous hypercortisolism, ovarian cancer and other disorders, according to the company.

As Healio previously reported, the phase 3 GRACE trial enrolled 152 adults with Cushing’s syndrome plus hypertension, hyperglycemia or both conditions. Participants received relacorilant for 22 weeks during an open-label phase. At 22 weeks, adults who met criteria for hypertension or hyperglycemia control entered a withdrawal phase where they were randomly assigned, 1:1, to continue relacorilant or switch to placebo for 12 weeks.

In the GRACE trial, adults with hypertension had a 7.9 mm Hg decrease in systolic blood pressure and a 5.1 mm Hg decline in diastolic BP at 22 weeks. During the randomized withdrawal phase, adults who remained on relacorilant had no change in systolic and diastolic BP, whereas those receiving placebo had a BP increase from the start of the phase to week 12.

In a press release from Corcept Therapeutics from 2024, the company announced results from the phase 3 GRADIENT trial, a randomized, double-blind, placebo-controlled trial where adults with Cushing’s syndrome caused by an adrenal adenoma or adrenal hyperplasia were randomly assigned, 1:1, to relacorilant or placebo for 22 weeks. According to the press release, the relacorilant group had a 6.6 mm Hg decline in mean systolic BP compared with baseline at 22 weeks. However, there was no significant difference in mean systolic BP change between the relacorilant and placebo groups.

As Healio previously reported, relacorilant was also assessed in a long-term extension study that enrolled adults who completed the GRACE and GRADIENT trials as well as a phase 2 hypercortisolism study. In that trial, relacorilant conferred a 10 mm Hg drop in 24-hour ambulatory systolic BP and a 7.3 mm Hg reduction in 24-hour ambulatory diastolic BP at 24 months.

In the company’s press release announcing receipt of the complete response letter, Corcept Therapeutics said the FDA acknowledged that the GRACE trial met its primary endpoint and that the GRADIENT trial provided “confirmatory evidence.” However, the FDA said it did not view relacorilant offered “a favorable benefit-risk assessment” without more data of its effectiveness, according to the press release.

“We are surprised and disappointed by this outcome,” Joseph K. Belanoff, MD, CEO of Corcept Therapeutics, said in a press release. “Our commitment to patients suffering from the effects of hypercortisolism is unwavering. I am confident we will find a way to get relacorilant to the patients it could help. We will meet with the FDA as soon as possible to discuss the best path forward.”
