Transsphenoidal Surgery Leads to Remission in Children with Cushing’s Disease

Posted on January 19, 2026 by MaryO

Transsphenoidal surgery — a minimally invasive surgery for removing pituitary tumors in Cushing’s disease patients — is also effective in children and adolescents with the condition, leading to remission with a low rate of complications, a study reports.

The research, “Neurosurgical treatment of Cushing disease in pediatric patients: case series and review of literature,” was published in the journal Child’s Nervous System.

Transsphenoidal (through the nose) pituitary surgery is the main treatment option for children with Cushing’s disease. It allows the removal of pituitary adenomas without requiring long-term replacement therapy, but negative effects on growth and puberty have been reported.

In the study, a team from Turkey shared its findings on 10 children and adolescents (7 females) with the condition, who underwent microsurgery (TSMS) or endoscopic surgery (ETSS, which is less invasive) — the two types of transsphenoidal surgery.

At the time of surgery, the patients’ mean age was 14.8 years, and they had been experiencing symptoms for a mean average of 24.2 months. All but one had gained weight, with a mean body mass index of 29.97.

Their symptoms included excessive body hair, high blood pressure, stretch marks, headaches, acne, “moon face,” and the absence of menstruation.

The patients were diagnosed with Cushing’s after their plasma cortisol levels were measured, and there was a lack of cortical level suppression after they took a low-dose suppression treatment. Measurements of their adrenocorticotropic (ACTH) hormone levels then revealed the cause of their disease was likely pituitary tumors.

Magnetic resonance imaging (MRI) scans, however, only enabled tumor localization in seven patients: three with a microadenoma (a tumor smaller than 10 millimeters), and four showed a macroadenoma.

CD diagnosis was confirmed by surgery and the presence of characteristic pituitary changes. The three patients with no sign of adenoma on their MRIs showed evidence of ACTH-containing adenomas on tissue evaluation.

Eight patients underwent TSMS, and 2 patients had ETSS, with no surgical complications. The patients were considered in remission if they showed clinical adrenal insufficiency and serum cortisol levels under 2.5 μg/dl 48 hours after surgery, or a cortisol level lower than 1.8 μg/dl with a low-dose dexamethasone suppression test at three months post-surgery. Restoration of normal plasma cortisol variation, eased symptoms, and no sign of adenoma in MRI were also requirements for remission.

Eight patients (80%) achieved remission, 4 of them after TSMS. Two patients underwent additional TSMS for remission. Also, 1 patient had ETSS twice after TSMS to gain remission, while another met the criteria after the first endoscopic surgery.

The data further showed that clinical recovery and normalized biochemical parameters were achieved after the initial operation in 5 patients (50%). Three patients (30%) were considered cured after additional operations.

The mean cortisol level decreased to 8.71 μg/dl post-surgery from 23.435 μg/dl pre-surgery. All patients were regularly evaluated in an outpatient clinic, with a mean follow-up period of 11 years.

Two patients showed pituitary insufficiency. Also, 2 had persistent hypocortisolism — too little cortisol — one of whom also had diabetes insipidus, a disorder that causes an imbalance of water in the body. Radiotherapy was not considered in any case.

“Transsphenoidal surgery remains the mainstay therapy for CD [Cushing’s disease] in pediatric patients as well as adults,” the scientists wrote. “It is an effective treatment option with low rate of complications.”

CV risk elevated in patients with adrenal incidentalomas, mild hypercortisolism

Posted on January 17, 2026 by MaryO

Patients with adrenal incidentalomas and mild hypercortisolism have an increased risk for cardiovascular events and mortality. This risk was evident even when clinical signs of overt hypercortisolism were not present, according to data published in The Lancet Diabetes & Endocrinology.

“Our findings are important because they add to the previously scant information about adrenal incidentalomas, which will be of use to doctors who are seeing an increasing number of patients with these masses,” Renato Pasquali, MD, of the S. Orsola-Malpighi Hospital in Bologna, Italy, said in a press release.

The retrospective study by Pasquali and colleagues assessed the adrenal incidentalomas of 198 outpatients treated every 18 to 30 months, with a mean follow-up of 7.5 years. At the time of follow-up, 114 patients demonstrated stable non-secreting adrenal incidentalomas (<50 nmol/L), 61 had either a stable intermediate phenotype (50 nmol/L-138 nmol/L) or subclinical Cushing’s syndrome (>138 nmol/L), and 23 patients had worsening pattern of secretion.

The incidence of CV events appeared higher in patients with a stable intermediate phenotype or subclinical Cushing’s syndrome (6.7% vs. 16.7%; P=.04) and in those with worsened secreting patterns (6.7% vs. 28.4%; P=.02) compared with patients with stable non-secreting adrenal incidentalomas, according to data.

In addition, CV events were independently related to changes in cortisol concentrations after the 1-mg dexamethasone suppression test (DST; HR=1.13; 95% CI, 1.05-1.21) from baseline to follow-up.

Patients with stable intermediate phenotype adrenal incidentalomas (57%) or subclinical Cushing’s syndrome (91.2%) tended to have lower survival rates for all-cause mortality (P=.005), researchers wrote. The main risk factors for all-cause mortality were age (HR=1.06; 95% CI, 1.01-1.12) and mean concentrations of cortisol after DST (HR=1.1; 95% CI, 1.01-1.19).

The unadjusted survival for CV-related mortality was lower in patients with either a stable intermediate phenotype (97.5%) or subclinical Cushing’s syndrome (78.4%; P=.02) vs. those with stable non-secreting adrenal incidentalomas (97.5%), and patients with worsened secreting patterns (60%; P=.01).

In an accompanying comment, Rosario Pivonello, MD, PhD, Maria Cristina De Martino, PhD, and Annamaria Colao, MD, PhD, of the Federico II University of Naples, Italy, wrote that the study supports the importance of long-term hormonal follow-up for clinical management of patients with adrenal incidentalomas.

“Furthermore, clinical monitoring of cardiometabolic risks seems to be important in these patients, particularly in those with subclinical Cushing’s syndrome and intermediate phenotype adrenal incidentalomas, for whom medical or surgical intervention could be needed,” they wrote.

They suggest long-term prospective studies to determine the frequency of new CV events and mortality in this patient population.

Think Like a Doctor: Red Herrings Solved!

Posted on January 11, 2026 by MaryO

By LISA SANDERS, M.D.

On Thursday we challenged Well readers to take the case of a 29-year-old woman with an injured groin, a swollen foot and other abnormalities. Many of you found it as challenging as the doctors who saw her. I asked for the right test as well as the right diagnosis. More than 200 answers were posted.

The right test was…

The dexamethasone suppression test,though I counted those of you who suggested measuring the cortisol in the urine.

The right diagnosis was…

Cushing’s disease

More than a dozen of you got the right answer or the right test, but Dr. Davin Quinn, a consultant psychiatrist at the University of New Mexico Hospital, was the first to be right on both counts. As soon as he saw that the patient’s cortisol level was increased, he thought of Cushing’s. And he had treated a young patient like this one some years ago as a second year resident.

The Diagnosis:

Cushing’s disease is caused by having too much of the stress hormone cortisol in the body. Cortisol is made in the adrenal glands, little pyramid shaped organs that sit atop the kidneys. It is normally a very tightly regulated hormone that helps the body respond to physical stress.

Sometimes the excess comes from a tumor in the adrenal gland itself that causes the little organ to go into overdrive, making too much cortisol. More often the excess occurs when a tumor in the pituitary gland in the brain results in too much ACTH, the hormone that controls the adrenal gland.

In the body, cortisol’s most fundamental job is to make sure we have enough glucose around to get the body’s work done. To that end, the hormone drives appetite, so that enough fuel is taken in through the food we eat. When needed, it can break muscle down into glucose. This essential function accounts for the most common symptoms of cortisol excess: hyperglycemia, weight gain and muscle wasting. However, cortisol has many functions in the body, and so an excess of the hormone can manifest itself in many different ways.

Cushing’s was first described by Dr. Harvey Cushing, a surgeon often considered the father of modern neurosurgery. In a case report in 1912, he described a 23-year-old woman with sudden weight gain, mostly in the abdomen; stretch marks from skin too thin and delicate to accommodate the excess girth; easy bruising; high blood pressure and diabetes.

Dr. Cushing’s case was, it turns out, a classic presentation of the illness. It wasn’t until 20 years later that he recognized that the disease had two forms. When it is a primary problem of an adrenal gland gone wild and producing too much cortisol on its own, the disease is known as Cushing’s syndrome. When the problem results from an overgrown part of the pituitary making too much ACTH and causing the completely normal adrenal glands to overproduce the hormone, the illness is called Cushing’s disease.

It was an important distinction, since the treatment often requires a surgical resection of the body part where the problem originates. Cushing’s syndrome can also be caused by steroid-containing medications, which are frequently used to treat certain pulmonary and autoimmune diseases.

How the Diagnosis Was Made:

After the young woman got her lab results from Dr. Becky Miller, the hematologist she had been referred to after seeing several other specialists, the patient started reading up on the abnormalities that had been found. And based on what she found on the Internet, she had an idea of what was going on with her body.

“I think I have Cushing’s disease,” the patient told her endocrinologist when she saw him again a few weeks later.

The patient laid out her argument. In Cushing’s, the body puts out too much cortisol, one of the fight-or-flight stress hormones. That would explain her high blood pressure. Just about everyone with Cushing’s disease has high blood pressure.

She had other symptoms of Cushing’s, too. She bruised easily. And she’d been waking up crazy early in the morning for the past year or so – around 4:30 – and couldn’t get back to sleep. She’d heard that too much cortisol could cause that as well. She was losing muscle mass – she used to have well-defined muscles in her thighs and calves. Not any more. Her belly – it wasn’t huge, but it was a lot bigger than it had been. Cushing’s seemed the obvious diagnosis.

The doctor was skeptical. He had seen Cushing’s before, and this patient didn’t match the typical pattern. She was the right age for Cushing’s and she had high blood pressure, but nothing else seemed to fit. She wasn’t obese. Indeed, she was tall (5- foot-10) and slim (150 pounds) and athletic looking. She didn’t have stretch marks; she didn’t have diabetes. She said she bruised easily, but the endocrinologist saw no bruises on exam. Her ankle was still swollen, and Cushing’s can do that, but so can lots of other diseases.

The blood tests that Dr. Miller ordered measuring the patient’s ACTH and cortisol levels were suggestive of the disease, but many common problems — depression, alcohol use, eating disorders — can cause the same result. Still, it was worth taking the next step: a dexamethasone suppression test.

Testing, Then Treatment:

The dexamethasone suppression test depends on a natural negative feedback loop whereby high levels of cortisol suppress further secretion of the hormone. Dexamethasone is an artificial form of cortisol. Given in high doses, it will cause the level of naturally-occurring cortisol to drop dramatically.

The patient was told to take the dexamethasone pills the night before having her blood tested. The doctor called her the next day.

“Are you sure you took the pills I gave you last night?” the endocrinologist asked her over the phone. The doctor’s voice sounded a little sharp to the young woman, tinged with a hint of accusation.

“Of course I took them,” she responded, trying to keep her voice clear of any irritation.

“Well, the results are crazy,” he told her and proposed she take another test: a 24-hour urine test.

Because cortisol is eliminated through the kidneys, collecting a full day’s urine would show how much cortisol her body was making. So the patient carefully collected a day’s worth of urine.

A few days later, the endocrinologist called again: her cortisol level was shockingly high. She was right, the doctor conceded, she really did have Cushing’s.

An M.R.I. scan revealed a tiny tumor on her pituitary. A couple of months later, she had surgery to remove the affected part of the gland.

After recovering from the surgery, the patient’s blood pressure returned to normal, as did her red blood cell count and her persistently swollen ankle. And she was able to once again sleep through the night.

Red Herrings Everywhere:

As many readers noted, there were lots of findings that didn’t really add up in this case. Was this woman’s groin sprain part of the Cushing’s? What about the lower extremity swelling, and the excess red blood cell count?

In the medical literature, there is a single case report of high red blood cell counts as the presenting symptom in a patient with Cushing’s. And with this patient, the problem resolved after her surgery – so maybe they were linked.

And what about the weird bone marrow biopsy? The gastritis? The enlarged spleen? It’s hard to say for certain if any of these problems was a result of the excess cortisol or if she just happened to have other medical problems.

Why the patient didn’t have the typical symptoms of Cushing’s is easier to explain. She was very early in the course of the disease when she got her diagnosis. Most patients are diagnosed once symptoms have become more prominent

By the time this patient had her surgery, a couple of months later, the round face and belly characteristic of cortisol excess were present. Now, two years after her surgery, none of the symptoms remain.

Co-Occurrence of Endogenous and Exogenous Cushing’s Syndromes: Does “Double Cushing Syndrome” Really Exist? A Case Report

Posted on December 1, 2025 by MaryO

ABSTRACT

Double Cushing syndrome exists: exogenous steroid use can mask concurrent adrenal hypercortisolism. When symptoms persist and cortisol remains high after tapering or stopping prescribed glucocorticoids, an endogenous source is likely. Early recognition with ACTH testing, dexamethasone suppression, and adrenal imaging reduces misdiagnosis, favors timely surgery, and supports safe tapering.

1 Introduction

Cushing syndrome (CS) is a non-physiological increase in plasma glucocorticoids [1]. In most cases, the source of increased plasma glucocorticoids is caused by exogenous steroid administration, which is quite common, and about 1% of the world population is on long-term (more than 3 months) oral glucocorticoids [1, 2]. On the contrary, endogenous overproduction of glucocorticoids is rare, and annually, only two to eight per million people are diagnosed with endogenous CS [3]. The simultaneous occurrence of endogenous and exogenous CS is an exceptionally uncommon phenomenon. This dual manifestation has been reported in a few case reports, highlighting its rarity and the complex diagnostic and therapeutic challenges it poses [4, 5]. Therefore, in this study, we discuss a patient who presented with cushingoid features and was simultaneously diagnosed with both endogenous and exogenous CS or, as it is called, double CS.

2 Case Presentation

The patient was a 46-year-old male with a history of new-onset hypertension and recurrent deep vein thrombosis (DVT) who was referred to our endocrinology clinic with a chief complaint of hip pain and weakness of the lower limbs. In the past 3 years, the patient had been receiving 50 mg/day of oral prednisolone and inhalation powder of Umeclidinium and Vilanterol (62.5/25 μg/dose) because of respiratory complications that started after Coronavirus Disease 2019 (COVID-19) vaccination. After 3 months of corticosteroid treatment, he experienced DVT for the first time when he was started on rivaroxaban. However, while he was on treatment, the second DVT occurred 1 month before his referral, and therefore, rivaroxaban was changed to warfarin 5 mg/day.

The patient also mentioned weight gain with his body mass index (BMI) rising from 26 to 31 kg/m2, progressive weakness of proximal muscles, easy bruising, decreased libido, mood changes with mostly euphoric mood, and irritability during the last 2 years. Moreover, multiple osteoporotic fractures of ribs, clavicle, sternum, and lumbar vertebrae were added to his symptoms in the past 5 months. At that time, he underwent bone densitometry, which revealed osteopenia of the left hip with a Z-score of −1.3 and severe osteoporosis of total lumbar spine with a T-score of −3.9. He started taking calcium and vitamin D3 supplements and received a single injection of 750 μg/3 mL teriparatide 30 days before his referral to our center.

Two months ago, the patient gradually reduced the dosage of prednisolone by tapering the dose to 12.5 mg/day. However, a month later, the hip pain and muscle weakness worsened to such an extent that the patient was unable to walk. Due to his signs and symptoms, the patient was referred to our center for further evaluation of CS. The patient also mentioned a history of nephrolithiasis, new-onset hypertension, and lower limb edema, for which he was started on eplerenone 25 mg and furosemide 20 mg tablets once daily. In his family history, the patient’s mother had type 2 diabetes mellitus, and his two sisters had a history of nephrolithiasis. The patient did not mention any history of allergies to medications or foods. He was addicted to opium and had 15 pack-years of smoking, but he did not mention alcohol consumption.

Upon admission, the patient presented with a blood pressure of 150/83 mmHg, heart rate of 74 bpm, respiratory rate of 20/min, temperature of 36.5°C, oxygen saturation of 93%, and BMI of 31 kg/m2. He was sitting in a wheelchair due to weakness and severe pain in the hip. On physical examination, the patient showed the features of CS, including moon face, buffalo hump, central obesity, facial plethora, thin and brittle skin, acne, and purple stretch marks (striae) on the flanks (Figure 1). Proximal muscle weakness in the lower limbs with a muscle force grade of 4/5 and 3+ edema was also observed. Laboratory investigations are shown in Table 1.

1 mg Overnight dexamethasone suppression test (μg/dL) 16.5 — < 1.8

3 Methods (Differential Diagnosis, Investigations, and Treatment)

Initially suspected of having exogenous-induced CS, the patient’s prednisolone was on hold for 3 days. Cortisol 8 a.m. fasting level, measured with Electrochemiluminescence (ECL) and adrenocorticotropic hormone (ACTH) test, was 20.2 μg/dL (585.4 nmol/L) and < 1 pg/mL, respectively. Due to the lack of suppression of serum cortisol despite not using oral glucocorticoids, the absence of adrenal insufficiency symptoms, and the fact that the patient’s symptoms remained unchanged during this period, co-occurrence of endogenous CS was suspected.

A 1 mg overnight dexamethasone suppression test was performed to confirm endogenous CS diagnosis, and the results were reported as 16.5 μg/dL (normal range < 1.8 μg/dL). Considering the possibility of an ACTH-independent CS, the patient underwent an abdominopelvic multidetector computed tomography (MDCT) of abdominopelvic with adrenal protocol, which revealed a well-defined lesion with an approximate size of 32.8 × 38.6 mm in the left adrenal gland with a radiodensity of 90 Hounsfield units and a normal right adrenal gland (Figure 2). Moreover, evidence of previous old fractures as multiple callus formation was seen involving the clavicles, sternum, bilateral ribs, ischium, and pelvic bones. Multilevel old stable compression fractures of thoracic and lumbar vertebral bodies were also present. The differential diagnoses were glucocorticoid secretory adrenal tumors, including adrenal cell carcinoma and lipid-poor adenoma. In order to rule out pheochromocytoma, 24-h urine catecholamines were measured, and the results were negative.

Finally, the patient underwent left adrenalectomy and corticosteroid replacement therapy due to the suppression of the other adrenal gland. According to the post-operative pathological investigations, immunohistochemistry markers reported as negative chromogranin, positive melan-A and inhibin, less than 3% Ki-67 marker, and lipid-poor adrenal cortical adenoma without invasions were diagnosed (Figure 3).

4 Results (Outcome and Follow-Up)

Within 3 months after the operation, the patient’s corticosteroid was tapered and then discontinued due to the normalization of the cortisone serum test (14.1 μg/dL). Proximal limb weakness and hip pain, which had deprived the patient of the ability to move, gradually improved so that he could walk easily and perform daily activities. The signs and symptoms related to CS, including the patient’s mood, skin signs, and general appearance, returned to normal. The patient has been followed up for 6 months after the surgery. The patient’s BMI decreased to 24 kg/m2, and he stopped his anti-hypertensive medications with a blood pressure of 100/60 mmHg without previously prescribed drugs. So far, the laboratory tests have been within the normal range, and he has no complaints (Table 1).

5 Discussion

The described case was diagnosed with a cortisol-producing adrenocortical adenoma accompanied by exogenous CS. CS is an uncommon clinical condition caused by prolonged exposure to increased cortisol levels, which can be due to endogenous or exogenous factors [6]. Endogenous CS is infrequent and is classified as ACTH-dependent (80% of cases) or ACTH-independent (20% of cases) [7]. In the ACTH-independent category, adrenal adenoma accounts for 60% of cases and only 12% of cases of endogenous CS [7, 8]. Exogenous CS mainly occurs due to prolonged administration of glucocorticoids, which are used to manage a broad spectrum of diseases such as inflammatory, autoimmune, or neoplastic disorders and are the most common cause of CS worldwide [9]. Multiple factors, including formulation, duration of administration, pharmacokinetics, affinity, and potency of exogenous glucocorticoids, affect the probability of exogenous CS, but all forms of glucocorticoids can induce CS [10].

In the setting of cushingoid clinical features with chronic administration of high-dose glucocorticoids, especially oral prednisolone, the probability of exogenous CS is remarkably high; therefore, CS diagnostic approaches suggest that the first step after confirmation of cortisol excess is ruling out exogenous glucocorticoid administration [7, 8, 10]. Therefore, the possibility of co-occurrence of endogenous CS with iatrogenic CS is extremely low, and the diagnosis requires high clinical suspicion [4].

Differentiating endogenous and exogenous CS based on clinical features can be challenging and far-fetched. However, a few points can help physicians distinguish between these two. First, exogenous CS symptoms tend to be more striking, while endogenous CS appears more gradually. Second, hypertension, hypokalemia, and features of androgen excess, such as acne and hirsutism, are more common in endogenous CS [4, 10]. In addition, endogenous CS should be suspected if the patient’s symptoms continue after corticosteroid discontinuation or if the serum cortisol level is high despite corticosteroid cessation. In our case, the patient had a high cortisol level despite stopping prednisolone for 3 days, and he did not have any symptoms of adrenal insufficiency despite stopping prednisolone suddenly. Consequently, it was suspected that glucocorticoids might come from an endogenous source. Because ACTH was suppressed concurrently with elevated cortisol, non-ACTH-dependent CS was suspected, and MDCT of abdominopelvic confirmed it.

So far, few similar cases of simultaneous endogenous and exogenous CS have been reported. The first case was a 23-year-old woman with juvenile idiopathic arthritis who was administered high doses of triamcinolone for 16 years [4]. The development of cushingoid features that favored endogenous CS, such as hirsutism and acne, strengthened the suspicion of endogenous CS, and a CT scan revealed hypercortisolism with a bulky and nodular left adrenal gland, and a double CS was confirmed [4]. The second case was a 66-year-old woman diagnosed with exogenous CS after consumption of Traditional Chinese medicine (TCM) for a year [5]. The cessation of TCM did not significantly improve her cushingoid features, and she developed additional CS complications, including hypertension, diabetes mellitus, and osteoporotic fractures over the next 8 years. CS workup revealed a right-sided adrenal adenoma, and after the adrenalectomy, her clinical cushingoid features markedly improved [5]. These cases suggest that exogenous and endogenous CS can exist simultaneously in the same person. Although it is very rare, it should be considered in a person who still complains of CS symptoms after corticosteroid cessation. We suggest clinicians evaluate the patients for the disappearance of exogenous CS symptoms after tapering and stopping glucocorticoids. If the symptoms remain, they should be evaluated for endogenous CS.

6 Conclusion

The co-occurrence of an endogenous CS in the setting of an exogenous CS is curious. The diagnosis is based on a high clinical suspicion. Clinicians should evaluate patients for symptom resolution after tapering and discontinuing corticosteroids. Clinical cushingoid features that do not resolve after discontinuing exogenous glucocorticoids and high cortisol levels despite discontinuing corticosteroids should raise clinicians’ suspicion of the co-occurrence of exogenous and endogenous CS.

Metyrapone Benefits Blood Pressure in Mild Hypercortisolism

Posted on November 7, 2025 by MaryO

TOPLINE:

A notable proportion of patients with mild hypercortisolism achieved blood pressure (BP) control with low-dose evening metyrapone, without requiring the intensification of antihypertensive therapy. The treatment was particularly beneficial for those with higher baseline systolic BP and was well tolerated, with no adverse events reported.

METHODOLOGY:

  • This prospective observational study assessed the impact of low-dose evening metyrapone on 24-hour ambulatory BP, glucose metabolism, and the cortisol circadian rhythm in 20 patients with mild hypercortisolism (median age, 70.5 years; 65% women).
  • Eligible patients had cortisol levels > 1.8 μg/dL after a 1-mg dexamethasone suppression test on at least two separate occasions, fewer than two specific Cushing syndrome‑related symptoms, and either hypertension or impaired glucose metabolism.
  • Patients received evening metyrapone 250 mg/d, with dose adjustments on the basis of clinical response and cortisol secretion; in 12 patients who showed no signs of hypoadrenalism after week 12, an additional 250-mg afternoon dose was given.
  • The primary endpoint was BP control, defined as a reduction in mean 24-hour systolic BP of ≥ 5 mm Hg without increasing antihypertensive medication; ambulatory BP monitoring was done at baseline and weeks 12 and 24.

TAKEAWAY:

  • At 24 weeks, 40% of patients had a clinically significant improvement in BP control without escalation of therapy, with reductions in both daytime and nighttime systolic BP; benefits were more pronounced in those with elevated baseline systolic BP.
  • Glucometabolic control improved in four patients at 24 weeks; those with poorly controlled type 2 diabetes at baseline achieved the most pronounced glycaemic benefits.
  • Salivary cortisol levels remained unchanged from baseline; no significant changes in hormonal, metabolic, or anthropometric parameters were observed from baseline, except for testosterone levels in women.
  • The treatment was well tolerated, with no side effects or reports of adrenal insufficiency.

IN PRACTICE:

“Our findings support the notion that metyrapone may offer clinical benefits in patients with mH [mild hypercortisolism], particularly those with uncontrolled comorbidities. The observed improvements in BP and glycaemic control, despite minimal changes in UFC [urinary free cortisol] levels, underscore the need to re-evaluate traditional therapeutic targets and to adopt a more holistic approach to disease management,” the authors of the study wrote.

SOURCE:

This study was led by Antonio Musolino, University of Milan, Milan, Italy. It was published online on October 16, 2025, in the European Journal of Endocrinology.

LIMITATIONS:

This study was limited by its relatively short treatment duration, potential adherence bias, and an older cohort age, which may have limited generalisability. The sample size, although adequate for the primary endpoint, was limited. The absence of a control group restricted the ability to definitively attribute improvements to metyrapone therapy.

DISCLOSURES:

This study received financial support through an investigator-initiated study grant from ESTEVE (formerly HRA RD). Two authors reported receiving speaker or consultancy fees or honoraria from Corcept Therapeutics.
