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.

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.

Global Longitudinal Strain Reduction With Apical Sparing in Cushing Syndrome-Related Heart Failure With Preserved Ejection Fraction (HFpEF)

Posted on October 6, 2025 by MaryO

We describe a case of a 56-year-old woman with a history of recurrent pituitary adenoma, not well followed, and known comorbidities of coronary artery disease, hypertension, and type 2 diabetes mellitus. She arrived with severely high blood pressure and signs pointing to hypercortisolism.

Further evaluation revealed left ventricular hypertrophy, reduced global longitudinal strain, and preserved left ventricular ejection fraction, consistent with heart failure with preserved ejection fraction (HFpEF). Workup for amyloidosis was negative.

This case highlights that chronic hypercortisolism may cause pathophysiological changes in the heart, leading to HFpEF, and may induce myocardial fibrosis and impaired myocardial mechanics, producing an echocardiographic pattern that can mimic infiltrative cardiomyopathy. Recognition of this overlap is crucial to avoid misdiagnosis and to ensure timely endocrine and cardiovascular management.

Cushing Syndrome Leaves Lasting Health Effects

Posted on August 8, 2025 by MaryO

TOPLINE:

Compared with a matched population-based control group, patients with Cushing syndrome continued to exhibit elevated systolic and diastolic blood pressures along with reduced kidney function at least 14 years after biochemical remission.

METHODOLOGY:

  • Researchers in Germany conducted a retrospective cohort study to assess the long-term trajectory of blood pressure and kidney function in patients who achieved remission of Cushing syndrome.
  • They included 81 patients with Cushing syndrome (median age at baseline, 44 years; 75.3% women) and compared them with 243 matched control individuals from a population-based cohort.
  • Data were collected before treatment at baseline and at median follow-up intervals of 7.1 and 14 years after biochemical remission, with assessments of blood pressure, glomerular filtration rate, the prevalence of chronic kidney disease, and the use of antihypertensives.

TAKEAWAY:

  • Patients with Cushing syndrome had a significant reduction in blood pressure and required fewer antihypertensives at both 7 and 14 years vs baseline.
  • However, when compared with the control group, patients with Cushing syndrome had significantly elevated systolic and diastolic pressures at baseline and 7 and 14 years post-remission (P ≤ .0002 for all).
  • Although the proportion of patients on antihypertensive medications decreased in the Cushing syndrome group after remission was achieved, the prevalence of uncontrolled hypertension remained higher than in the control group at all follow-up points. In fact, reducing the use of these medications was associated with an increased risk for uncontrolled hypertension.
  • Kidney function assessed via glomerular filtration rate remained consistently lower among patients with Cushing syndrome than among control individuals at baseline and 7 and 14 years post-remission (P = .005, P < .0001, and P = .0359, respectively).

IN PRACTICE:

“Our findings provide further evidence that cardiovascular effects of hypercortisolism are not entirely reversible with the normalization of cortisol levels and enhance our understanding of the deteriorative long-term cardiovascular consequences of chronic hypercortisolism,” the authors wrote.

SOURCE:

This study was led by Katrin Ritzel, Ludwig-Maximilians-Universität München (LMU Munich), LMU University Hospital in Munich, Germany. It was published online on July 29, 2025, in Journal of Endocrinological Investigation.

LIMITATIONS:

The retrospective design and single-centre nature of this study could have been considered limitations.

From Weight Gain To Diabetes

Posted on March 10, 2025 by MaryO
Cushing’s syndrome happens when the body has too much cortisol, the stress hormone. It can cause weight gain, high blood pressure, and diabetes. So how to keep your health in check and what are the treatment options available? In an exclusive interview with Times Now, an Endocrinologist explains its symptoms, causes, and treatments.
We often blame stress for everything—from sleepless nights to stubborn weight gain. But did you know your body’s stress hormone, cortisol, could be at the root of more serious health issues like high blood pressure and diabetes? Yes, you read that right! But how? We got in touch with Dr Pranav A Ghody, Endocrinologist at Wockhardt Hospital, Mumbai Central, who explains how excessive cortisol levels can lead to a condition known as Cushing’s Syndrome.
What Exactly is Cortisol, and Why is it Important?
Hormones are the body’s chemical messengers, travelling through the bloodstream to regulate essential functions. Among them, cortisol, produced by the adrenal glands (tiny glands sitting above the kidneys), plays a crucial role in controlling blood pressure, blood sugar, energy metabolism, and inflammation. The pituitary gland, located at the base of the brain, regulates cortisol through another hormone called Adrenocorticotropic Hormone (ACTH).
Often referred to as the “stress hormone,” cortisol spikes when we’re under stress. However, when levels remain high for too long, it can lead to Cushing’s Syndrome, a disorder first identified in 1912 by Dr Harvey Cushing.

What Causes Cushing’s Syndrome?

Dr Ghody explains that Cushing’s Syndrome occurs when the body is exposed to excessive cortisol, which can happen in two ways:

1. Exogenous (External) Cushing’s Syndrome
This is the most common form and results from prolonged use of steroid medications (such as prednisone) to treat conditions like asthma, rheumatoid arthritis, and lupus, or to prevent transplant rejection. Since steroids mimic cortisol, long-term use can disrupt the body’s hormone balance.
2. Endogenous (Internal) Cushing’s Syndrome
This occurs when the body produces too much cortisol due to a tumour in the pituitary gland, adrenal glands, or other organs (lungs, pancreas, thymus). While rare—affecting about 10 to 15 people per million annually—it’s more common in women between 20 and 50 years old. When caused by a pituitary tumour, it’s specifically called Cushing’s Disease.

Symptoms: How To Recognize Signs Of Cushing’s Syndrome

Excess cortisol affects multiple organs, leading to a variety of symptoms. This includes:

– Weight gain around the belly (central obesity)
– Rounded, puffy face (moon face)
– Excess facial and body hair (hirsutism)
– Fat accumulation on the upper back (buffalo hump)
– Thin arms and legs
– Dark red-purple stretch marks on the chest and abdomen
– Extreme fatigue and muscle weakness
– Depression or anxiety
– Easily bruising with minimal trauma
– Irregular menstrual cycles in women
– Reduced fertility or low sex drive
– Difficulty sleeping
High blood pressure and newly diagnosed or worsening diabetes are also common red flags.

Why is Cushing’s Syndrome Often Misdiagnosed?

Dr Ghody explains that while severe cases of Cushing’s Syndrome are easier to identify, milder forms can often be missed or mistaken for conditions like obesity, diabetes, or polycystic ovary syndrome (PCOS).

Diagnosing Cushing’s Syndrome involves:
1. Measuring cortisol levels in the blood, urine, or saliva.
2. Identifying the source through ACTH hormone testing, MRI/CT scans, and advanced techniques like Inferior Petrosal Sinus Sampling (IPSS) or nuclear medicine scans
Treatment Options: How is Cushing’s Syndrome Managed?
Once diagnosed, the treatment depends on the cause:
– If due to steroid medication, the dosage is gradually reduced under medical supervision.
– If caused by a tumour, surgery is the primary treatment. Some patients, especially those with pituitary tumours, may require repeat surgery, gamma knife radiosurgery, or medications to control cortisol levels.

Can You Prevent Cushing’s Syndrome?

While complete prevention isn’t always possible, Dr Ghody shares some key strategies to reduce risk:

– Use steroids cautiously – If prescribed, take the lowest effective dose for the shortest time. Never stop abruptly without consulting a doctor.
– Genetic screening for people at risk – If you have a family history of pituitary or adrenal tumours, regular monitoring can help with early detection.
– Maintain a healthy lifestyle – A diet rich in fresh vegetables, and fruits, low sodium intake, adequate calcium, and vitamin D can help manage the metabolic effects of excess cortisol.
– Avoid alcohol and tobacco – These can further disrupt hormone balance and overall health.
“Cushing’s Syndrome can be life-threatening if left untreated, but early diagnosis and proper management can significantly improve quality of life. So if you experience unexplained weight gain, blood pressure spikes, or other symptoms, consult an endocrinologist to manage hormonal imbalances,” he said.

Spontaneous Cushing’s Disease Remission Induced by Pituitary Apoplexy

Posted on July 17, 2024 by MaryO

Abstract

Spontaneous remission of Cushing’s disease (CD) is uncommon and often attributed to pituitary tumor apoplexy. We present a case involving a 14-year-old female who exhibited clinical features of Cushing’s syndrome. Initial diagnostic tests indicated CD: elevated 24h urinary cortisol (235 µg/24h, n < 90 µg/24h), abnormal 1 mg dexamethasone overnight test (cortisol after 1 mg dex 3.4 µg/dL, n < 1.8 µg/dL), and elevated adrenocorticotropic hormone concentrations (83.5 pg/mL, n 10-60 pg/mL). A pituitary adenoma was suspected, so a nuclear MRI was performed, with findings suggestive of a pituitary microadenoma. The patient was referred for a transsphenoidal resection of the microadenoma. While waiting for surgery, the patient presented to the emergency department with a headache and clinical signs of meningism. A computed axial tomography of the central nervous system was performed, and no structural alterations were found. The symptoms subsided with analgesia. One month later, she presented again to the emergency department with clinical findings of acute adrenal insufficiency (cortisol level of 4.06 µg/dL), and she was noted to have spontaneous biochemical remission associated with the resolution of her symptoms of hypercortisolism. For that reason, spontaneous CD remission induced by pituitary apoplexy (PA) was diagnosed. The patient has been managed conservatively since the diagnosis and remains in clinical and biochemical remission until the present time, after 10 months of follow-up. There are three unique aspects of our case: the early age of onset of symptoms, the spontaneous remission of CD due to PA, which has been rarely reported in the medical literature, and the fact that the patient presented a microadenoma because there are fewer than 10 clinical case reports of PA associated with microadenoma.

Introduction

Cushing’s disease (CD) is characterized by excessive production of adrenocorticotropic hormone by a pituitary adenoma and represents the most common cause of endogenous Cushing’s syndrome (CS) [1]. CD was first reported in 1912 by Harvey Williams Cushing, and he described 12 cases at the Peter Bent Brigham Hospital in Baltimore [2]. This disease has a global incidence of approximately 2.2 cases per 1,000,000 people and occurs more frequently in women from 20 to 50 years of age [3]. Pituitary apoplexy (PA) is a rare condition that occurs in 2-12% of cases, and it has a high morbidity and mortality rate [4]. We report an interesting case of a woman diagnosed with CD who achieved spontaneous remission of her disease after a PA.

Case Presentation

A 14-year-old female presented with a two-year history of weight gain (32 kg), depression, elevated blood pressure, type 2 diabetes mellitus, and growth failure (height less than the third percentile). Her height was 140 cm, and her BMI was 28.1 (97th percentile). At presentation, she had not yet reached menarche. Physical examination revealed Tanner 2 breast development, acne, hirsutism, moon facies, dorsocervical fat pad, central obesity, and stretch marks. Initial laboratory tests showed hemoglobin A1C of 13%, low-density lipoprotein of 167 mg/dL, triglycerides of 344 mg/dL, high-density lipoprotein of 26 mg/dL, creatinine of 0.4 mg/dL, and elevated liver enzymes. Abdominal ultrasound indicated moderate hepatic steatosis changes.

Given the high suspicion of CS, a hormonal profile was conducted (Table 1), confirming CS and subsequently diagnosing CD. A nuclear MRI revealed a 2.6 × 1.8 mm pituitary lesion (Figure 1), prompting referral for transsphenoidal resection of the pituitary microadenoma.

Approximately one month after the suppression tests and while awaiting surgery, the patient presented to the emergency department with a sudden, severe, holocranial headache accompanied by projectile vomiting and diplopia, suggestive of meningism. A computed axial tomography of the central nervous system was conducted, revealing no structural abnormalities. Symptoms resolved with intravenous analgesia within approximately four to six hours. Subsequently, the patient experienced a significant decrease in insulin requirements, ultimately leading to the suspension of insulin therapy due to persistent hypoglycemia.

Weeks after the headache episode, the patient was reevaluated in the emergency department with a three-day history of diffuse abdominal pain, vomiting, asthenia, myalgia, hypotension, tachycardia, orthostatism, and recurrent hypoglycemia despite insulin suspension. Acute adrenal insufficiency was suspected and confirmed by a cortisol level of 4.06 µg/dL. Treatment with intravenous hydrocortisone 50 mg every six hours was initiated, leading to complete resolution of symptoms within 72 hours. The patient was discharged on maintenance therapy with oral hydrocortisone (20 mg in the morning and 10 mg at night). Subsequent follow-ups showed undetectable cortisol levels. Currently, the patient has been followed up for 10 months post-event, showing persistent clinical and hormonal remission of her disease.

Discussion

CD represents approximately 80% of cases of endogenous hypercortisolism, and pituitary microadenomas are the most common cause of CD in all age groups [5]. CD prevalence is 0.3-6.2 cases per 100,000 people [3], which represents 4.4% of all pituitary adenomas [6], and it is up to five times more likely to occur in women than men. Spontaneous remission of CD is rare, and it is mainly due to the apoplexy of a pituitary tumor [7].

PA is a potentially fatal condition resulting from hemorrhage or necrosis of a pituitary adenoma that produces compression of the surrounding structures with symptoms that can be critical and even fatal [8]. PA affects between 2% and 12% of patients with pituitary adenomas, mainly in nonfunctional macroadenomas [9]. Although the main mechanism of PA is hemorrhage, it can also be due to a hemorrhagic infarction or an infarction without hemorrhage; this last scenario is clinically less aggressive [10]. Among the most important precipitating factors are craniocerebral trauma, pregnancy, thrombocytopenia, coagulopathies, pituitary stimulation tests, drugs such as anticoagulants and estrogens, surgeries that are complicated by hypotension, and radiotherapy [4,11,12].

There are three unique aspects of our case. First, the age of onset is 14 years old. This characteristic has been reported in less than 6% of cases of CD, with a mean age of onset between 12.3 and 14.1 years and a slightly higher incidence in men (63%) [13]. In this population, CD is the most common cause of hypercortisolism, accounting for 75-80% of all cases [14]. Furthermore, our patient presented a significant weight gain, severe compromise in her height, hypertension, depression, and diabetes mellitus, which is compatible with the classic profile described for CD in pediatric ages. It is important to clarify that although type 2 diabetes mellitus is common in adults, it is unusual in the pediatric population [13].

Second, spontaneous remission in CD due to apoplexy has been rarely reported in the past; hence, our case is an important addition to the scant literature on this unusual phenomenon. Although there are characteristics suggestive of PA, such as hyperdense lesions within the pituitary gland and the reinforcing ring, a CT scan has a low sensitivity for detecting pituitary hemorrhage (21-46%); therefore, a negative CT scan does not rule out PA in cases where there is infarction without hemorrhage, a situation that could correspond to our case [15].

The third unique feature of our case is that the stroke occurred in the context of a microadenoma, a situation reported in less than 10 cases in the literature. Despite being a microadenoma, the symptoms of PA were severe, with symptoms of meningism, an intense headache, vomiting, and the development of adrenal insufficiency. Taylor et al. [16] reported a similar case of a 41-year-old female with microadenoma whose PA was associated with severe headache and vomiting.

The main differential diagnosis in our case is cyclical CS (CCS), a disorder that occurs in 15% of CS cases, especially in CD [17]. The diagnosis of CCS is classically established with three peaks and two valleys in cortisol secretion, spontaneous fluctuations, and clinical features of CS [7]. The possibility of CCS was ruled out due to the typical presentation of the PA event and the persistence of hypocortisolism.

Finally, several cases of recurrence of their disease have been described after remission of CS due to AP. Those recurrences usually develop in follow-ups of up to seven years [18]. At the time of the last evaluation (10 months post-PA), the patient remained in remission, but long-term follow-up is required to detect both reactivation and hypopituitarism [19].

Conclusions

CD is a rare entity in the pediatric population, usually associated with a pituitary microadenoma. Spontaneous remission of this disease is very uncommon, but when it occurs, it is mainly due to PA. We describe a case with three unique aspects: CD with an early age of onset of symptoms, spontaneous remission of CD due to PA, which has been rarely reported in the medical literature, and the fact that there are less than 10 clinical case reports of PA associated with microadenoma. It is imperative for clinicians to be aware of this possible outcome in patients with CD.
