Cushing Patients Could Be Diagnosed, Subtyped Using Plasma Steroid Levels

Posted on January 10, 2026 by MaryO

Patients with different subtypes of Cushing’s syndrome (CS) have distinct plasma steroid profiles. This could be used as a test for diagnosis and classification, a German study says.

The study, “Plasma Steroid Metabolome for Diagnosis and Subtyping Patients with Cushing Syndrome,” appeared in the journal Clinical Chemistry.

A quick diagnosis of CS is crucial so that doctors can promptly give therapy. However, diagnosing CS is often complicated by the multiple tests necessary not just to diagnose the disease but also to determine its particular subtype.

Cortisol, which leads to CS when produced at high levels, is a steroid hormone. But while earlier studies were conducted to determine whether patients with different subtypes of CS had distinct steroid profiles, the methods researchers used were cumbersome and have been discontinued for routine use.

Recently, a technique called LC-MS/MS has emerged for multi-steroid profiling in patients with adrenocortical dysfunction such as congenital adrenal hyperplasia, adrenal insufficiency and primary aldosteronism.

Researchers at Germany’s Technische Universität in Dresden used that method to determine whether patients with the three main subtypes of CS (pituitary, ectopic and adrenal) showed differences in plasma steroid profiles. They measured levels of 15 steroids produced by the adrenal glands in single plasma samples collected from 84 patients with confirmed CS and 227 age-matched controls.

They found that CS patients saw huge increases in the plasma steroid levels of 11-deoxycortisol (289%), 21-deoxycortisol (150%), 11-deoxycorticosterone (133%), corticosterone (124%) and cortisol (122%), compared to patients without the disease.

Patients with the ectopic subtype had the biggest jumps in levels of these steroids. However, plasma 18-oxocortisol levels were particularly low in ectopic disease. Other steroids demonstrated considerable variation.

Patients with the adrenal subtype had the lowest concentration of dehydroepiandrosterone (DHEA) and DHEA-SO4, which are androgens. Patients with the ectopic and pituitary subtype had the lowest concentration of aldosterone.

Through the use of 10 selected steroids, patients with different subtypes of CS could be identified almost as closely as with other tests, including the salivary and urinary free cortisol test, the dexamethasone-suppressed cortisol test, and plasma adrenocorticotropin levels. The misclassification rate using steroid levels was 9.5 percent, compared to 5.8 percent in other tests.

“This study using simultaneous LC-MS/MS measurements of 15 adrenal steroids in plasma establishes distinct steroid metabolome profiles that might be useful as a test for CS,” the team concluded, adding that using LC-MS/MS is advantageous, as specimen preparation is simple and the entire panel takes 12 minutes to run. This means it could be offered as a single test for both identification and subtype classification.

Long-Term Obesity Persists Despite Pituitary Adenoma Treatment In Childhood

Posted on January 9, 2026 by MaryO

Sethi A, et al. Clin Endocrinol. 2019;doi:10.1111/CEN.14146.

January 5, 2020

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

Cushing’s Syndrome Treatments

Posted on January 7, 2026 by MaryO
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.

Genetic mutation lowers obesity in Cushing’s syndrome

Posted on January 5, 2026 by MaryO

London E. J Clin Endocrinol Metab. 2013; doi:10.1210/jc.2013-1956.

Among adult patients with Cushing’s syndrome, those with mutations in PRKAR1A, the gene that controls cAMP-dependent protein kinase, are less obese than their counterparts without these mutations, according to a recent study.

The retrospective study evaluated adrenalectomy samples from 51 patients with Cushing’s syndrome, 13 with PRKAR1A mutations and 32 without. Of the 51 patients, 40 were female and 11 were male, and patients ranged in age from 4 to 74 years.

A non-Cushing’s syndrome comparison group consisting of 6 adrenalectomy patients with aldosterone producing adenomas (APAs) was included. Additional comparison groups comprising clinical data from 89 patients with Cushing’s disease and 26 with hyperaldosteronism were also studied.

Researchers recorded the weight, height and BMI of all patients, and measured abdominal subcutaneous adipose tissue (ScAT) and periadrenal adipose tissue (PAT) using computed tomography. PAT was collected and frozen for evaluation; the extracts were assessed for levels of cAMP and protein kinase (PKA) activity, as well as for protein and mRNA expression of subunits of PKA. Diurnal cortisol levels and urine-free cortisol were also measured preoperatively.

The study found that in adults with Cushing’s syndrome, the mean BMI of those with PRKAR1A mutations was lower than that of patients with noPRKAR1A mutations (P<.05), and was not inconsistent with the hyperaldosteronism comparison group.

In pediatric patients with adrenal Cushing’s syndrome, the presence of PRKAR1A mutation did not have an impact on mean BMI z-scores. However, in comparison with pediatric patients with pituitary Cushing’s disease, the BMI z-scores were significantly lower in pediatric Cushing’s disease patients with PRKAR1Amutations (P<.05). Patients with Cushing’s syndrome without PRKAR1A mutations had significantly more PAT and ScAT than non-Cushing’s syndrome patients. Additionally, the ratio of basal-to-total (cAMP-triggered) PKA activity was significantly lower in patients with PRKAR1A mutations, suggesting greater proportions of active PKA (P<.005).

“These findings have obvious implications in the establishment of the diagnosis of CS in patients with PRKAR1A mutations: These patients may be leaner than other patients with [Cushing’s syndrome],” the study authors wrote. “Perhaps more importantly, our findings point to the importance of cAMP and or PKA signaling in the regulation of adiposity.”

Adrenal Crisis

Posted on December 8, 2025 by MaryO

Robin wrote a great blog post about Jackie and Sam dealing with Adrenal Crisis.  This is a very important article that all should read.  Be your own advocate!

New PDF! Managing Adrenal Insufficiency

New Podcast! Podcast: Adrenal Crisis

If left untreated, adrenal insufficiency can cause serious illness or death. But by working with their doctors and nurses, patients can learn how to manage this condition.

A Paramedic wrote on the message boards:

I’d like to add a couple things from the perspective of a Paramedic…

A lot of us are not taught about adrenal insufficiency during our education….nor do many of us (if any at all) have a protocol to administer Injectable for AI unless we are able to contact the ER doctor for permission. So…if any of you should have an AI crisis please gently nudge your paramedic to contact the receiving physician for permission to administer the medication. I know this sounds like a lot of responsibility on the part of the patient…but you have to realize that we’re taught to recognize the most common life threats and endocrine disorders (other than diabetes) most usually do not present with life threats (we all know that as cushing’s is more recognized that this will change)…and our protocols cover the most common life threats….so while we may recognize that you are hypotensive and need fluids (IV) and are sweaty, nauseated, decreased level of responsiveness etc…we are not equipped to deal with the actual cause unless you help educate us….

Also…please don’t get angry with us….if we are having problems understanding…just gently insist that a call be made to your doctor or the receiving ED (usually not feasible for us to call your doctor since they do not come to the phone for just anybody but if you have access to them, as many cushies do, it would be great to talk to them)…

Paramedicine is evolving….someday soon, hopefully, our education will include more diagnostic skills…untill just in the past 5 years or so we were NEVER to make a diagnosis at all…just treat the symptoms!!!! So there is hope out there for futher understanding of such a critical problem for those without adrenal (or asleep adrenals) glands….

The medical alert jewerly is a life-saver and we do look for it….

Be sure to print this page to carry with you.

Alternative names:

adrenal crisis; Addisonian crisis; acute adrenal insufficiency

Definition:

An abrupt, life-threatening state caused by insufficient cortisol, a hormone produced and released by the adrenal gland.

Causes, incidence, and risk factors:

The two adrenal glands are located on top of the kidneys. They consist of the outer portion, called the cortex, and the inner portion, called the medulla. The cortex produces three types of hormones, which are called corticosteroids. The androgens and estrogens affect sexual development and reproduction. The glucocorticoids maintain glucose regulation, suppress the immune response, and provide for the response to stress (cortisol). The mineralocorticoids regulate sodium and potassium balance. These hormones are essential for life.

Acute adrenal crisis is an emergency caused by decreased cortisol. The crisis may occur in a person with Addison’s disease, or as the first sign of adrenal insufficiency. More uncommonly, it may be caused by a pituitary gland disorder. It may also be caused by sudden withdrawal of corticosteroids, removal or injury of the adrenal glands, or destruction of the pituitary gland. Risk factors are stress, trauma, surgery, or infection in a person with Addison’s disease, or injury or trauma to the adrenal glands or the pituitary gland. The incidence is 4 out of 100,000 people.

Prevention:

People who have Addison’s disease should be taught to recognize signs of potential stress that may precipitate an acute adrenal crisis (cause it to occur suddenly and unexpectedly). Most people with Addison’s disease are taught to give themselves an emergency injection of hydrocortisone in times of stress. It is important for the individual with Addison’s disease to always carry a medical identification card that states the type of medication and the proper dose needed in case of an emergency. Never omit medication. If unable to retain medication due to vomiting, notify the health care provider.

Symptoms:

  • headache
  • profound weakness
  • fatigue
  • slow, sluggish, lethargic movement
  • nausea
  • vomiting
  • low blood pressure
  • dehydration
  • high fever
  • chills shaking
  • confusion or coma
  • darkening of the skin
  • rapid heart rate
  • joint pain
  • abdominal pain
  • unintentional weight loss
  • rapid respiratory rate
  • unusual and excessive sweating on face and/or palms
  • skin rash or lesion may be present
  • flank pain
  • appetite, loss

Signs and tests:

  • An ACTH (cortrosyn) stimulation test shows low cortisol.
  • The cortisol level is low.
  • The fasting blood sugar may be low.
  • The serum potassium is elevated.
  • The serum sodium is decreased.
  • This disease may also alter the results of the following tests:
    • sodium, urine
    • 17-hydroxycorticosteroids

Treatment:

In adrenal crisis, an intravenous or intramuscular injection of hydrocortisone (an injectable corticosteroid) must be given immediately. Supportive treatment of low blood pressure is usually necessary. Hospitalization is required for adequate treatment and monitoring. Low blood pressure may be treated with intravenous fluids. If infection is the cause of the crisis, antibiotic therapy is indicated.

Expectations (prognosis):

Death may occur due to overwhelming shock if early treatment is not provided.

Complications:

  • shock
  • coma
  • seizures
