We report a case of severe EAS in a young Tunisian man resulting from a well differentiated Neuroendocrine Tumor (NET) of the lung. Besides catabolic signs and profound hypokalemia orienting towards Cushing’s Syndrome (CS), psychiatric symptoms were particularly severe, dominant and atypical including persecutory delusions, depression and anxiety.

Etomidate in the Treatment Of Cushing Syndrome

Posted on September 25, 2023 by MaryO

Cushing syndrome is a metabolic disease caused by chronic exposure to high levels of glucocorticoids. It can present as an endocrine emergency due to a rapid increase in circulating cortisol leading to increased risk of cardiovascular disease and infection. Etomidate rapidly reduces plasma cortisol levels by inhibiting the action of 11β-hidroxilase. We report the case of a patient with severe hypercortisolaemia accompanied by metabolic and psychiatric disorders in whom administration of etomidate reduced preoperative levels of cortisol.

Introduction

Cushing’s syndrome is a metabolic disease caused by chronic exposure to high levels of glucocorticoids. The main causes are ectopic ACTH secretion, adrenal tumours (adenomas or carcinomas), adrenal hyperplasia, and administration of exognous glucocorticoids—the latter being the most common aetiology.1

In most cases, Cushing’s syndrome presents an indolent course for years before diagnosis is made, although it can sometime present as an endocrine emergency due to a rapid increase in circulating cortisol levels.2 In these cases, treatment to control hypercortisolaemia must be started quickly due to the high morbidity and mortality associated with the potentially life-threatening metabolic, infectious, and neuropsychiatric alterations that occur in this syndrome.1, 2, 3, 4

The options for treating Cushing’s syndrome include surgery, radiotherapy, and pharmacological treatment. The most commonly used drugs are adrenal steroidogenesis inhibitors (ketoconazole, metyrapone),3 but this treatment is not always well tolerated and its efficacy is limited.2 Etomidate is a drug from the imidazole family that inhibits the enzyme 11β-hydroxylase, and can reduce cortisol secretion within 48−72 h.2

Case report

Our patient was a 27-year-old woman with no known drug allergies or personal history of interest. She was studied in April 2021 for anxious-depressive symptoms with rapidly evolving paranoid ideation and hirsutism. A Nugent test was performed, which was positive (46.1 mcg/dl), and cortisol in urine was measured (2715 mcg/24 h), leading to a diagnosis of Cushing’s syndrome.

A CT scan showed a large mass on the right adrenal gland, compatible with a primary adrenal gland tumour (Fig. 1).

Discussion

Endogenous Cushing’s syndrome is characterized by over-production of cortisol. In patients such as ours, the syndrome presents in its most serious form, with very high hypercortisolaemia and metabolic, cardiovascular, and neuropsychiatric disorders. Cushing’s syndrome is a medical emergency due to its association with several comorbidities and its high rate of mortality.5 The first therapeutic option is surgical resection of the underlying tumour; however, the accompanying hypercortisolaemia

Conclusion

In its severe form, Cushing’s syndrome is a medical emergency that must be rapidly controlled.

Etomidate is both safe and effective, and has shown promising results in the treatment of severe hypercortisolaemia.

We believe that these patients should be admitted to the Anaesthesia Intensive Care Unit during etomidate therapy in order to monitor their level of consciousness, lung function, and haemodynamics, and to closely monitor cortisol and electrolyte levels.

Psychotropic drugs in patients with Cushing’s disease before diagnosis and at long-term follow-up

Posted on February 27, 2021 by MaryO

The Journal of Clinical Endocrinology & Metabolism, dgab079, https://doi.org/10.1210/clinem/dgab079

Abstract

Context

Psychiatric symptoms are common in Cushing’s disease (CD) and seem only partly reversible following treatment.

Objective

To investigate drug dispenses associated to psychiatric morbidity in CD patients before treatment and during long-term follow-up.

Design

Nationwide longitudinal register-based study.

Setting

University Hospitals in Sweden.

Subjects

CD patients diagnosed between 1990 and 2018 (N=372) were identified in the Swedish Pituitary Register. Longitudinal data was collected from 5 years before, at diagnosis and during follow-up. Four matched controls per patient were included. Cross-sectional subgroup analysis of 76 patients in sustained remission was also performed.

Main outcome measures

Data from the Swedish Prescribed Drug Register and the Patient Register.

Results

In the 5-year period before, and at diagnosis, use of antidepressants (OR 2.2[95%CI 1.3-3.7] and 2.3[1.6-3.5]), anxiolytics (2.9[1.6-5.3] and 3.9[2.3-6.6]) and sleeping pills (2.1[1.2-3.7] and 3.8[2.4-5.9]) was more common in CD than controls. ORs remained elevated at 5-year follow-up for antidepressants (2.4[1.5-3.9]) and sleeping pills (3.1[1.9-5.3]). Proportions of CD patients using antidepressants (26%) and sleeping pills (22%) were unchanged at diagnosis and 5-year follow-up, whereas drugs for hypertension and diabetes decreased. Patients in sustained remission for median 9.3 years (IQR 8.1-10.4) had higher use of antidepressants (OR 2.0[1.1-3.8]) and sleeping pills (2.4[1.3-4.7]), but not of drugs for hypertension.

Conclusions

Increased use of psychotropic drugs in CD was observed before diagnosis and remained elevated regardless of remission status, suggesting persisting negative effects on mental health. The study highlights the importance of early diagnosis of CD, and the need for long-term monitoring of mental health.

Addison’s disease may cause psychosis, say researchers

Posted on December 10, 2015 by MaryO

adrenal-glands

 

Research suggests that chronic adrenal insufficiency, more commonly known as Addison’s disease, may be responsible for psychiatric symptoms in those who suffer with it. Unfortunately, these symptoms are poorly understood and inadequately studied. In one case, a 41-year-old construction worker was admitted to a psychiatric clinic complaining of depression. He had trouble sleeping and concentrating and had lost 6 pounds due to a loss of appetite. He was placed on 20mg of fluoxetine but returned 2 weeks later complaining that the therapy did not work, and even reported hallucinating his ex-wife, who had recently died in a car accident. He returned again later 4 months later and was found to have a weak pulse, major hypotension, and hyponatremia and hyperkalemia. It was at this point that he was diagnosed with Addison’s disease.

The disease was first described by Thomas Addison in the mddle of the 19th century. It involves inadequate secretion from the adrenal glands, leading to lower secretion of glucocorticoids. Its usual symptom pigmentation involves fatigue, weight loss, nausea, vomiting, weakness and abdominal pain. Among its psychiatric symptoms are psychosis and delirium.

Endocrine Society Releases Guidelines on Treatment of Cushing’s Syndrome

Posted on August 26, 2015 by MaryO

To lessen the risk for comorbidity and death, the Endocrine Society’s newly published guidelines on the treatment of Cushing’s syndrome focus on surgical resection of the causal tumor with the goal of normalizing cortisol levels. Furthermore, there is increased emphasis on individualizing treatment options when choosing a second-line treatment.

In July 2015, the Endocrine Society published treatment guidelines to assist endocrinologists in appropriately initiating treatment or referring patients with Cushing’s syndrome to treatment. A task force of experts compiled evidence from systematic reviews and graded the strength of the recommendations.

“We hope that it will lead to improved treatment of comorbidities both before and after definitive treatment of the syndrome, and to increased individualization of patient treatment,” said chair of the task force Lynnette Nieman, MD, who is chief of the Endocrinology Consultation Service at the National Institutes of Health Clinical Center.

“There are two new drugs that were approved in 2012, and so I think that is what prompted the review. Still, medications are not the first line of treatment, but we have some new therapeutic options, and I think the idea was to help people understand where to use them,” Julie Sharpless, MD, assistant professor and director of the UNC Multidisciplinary Pituitary Adenoma Program, told Endocrinology Advisor.

“The primary treatment is surgical resection of the causal tumor(s). If that cannot be done (because the tumor is occult or metastatic) or is not successful, then the choice of secondary treatment should be individualized to the patient. The comorbidities of Cushing’s syndrome, for example hypertension and diabetes, should be treated separately as well,” Nieman said.

For example, the guidelines recommend surgical removal of the causative lesion, with the exception of cases which are unlikely to cause a drop in glucocorticoids or in patients who are not surgical candidates.

Likewise, in patients with benign unilateral adrenal adenoma, adrenalectomy by an experienced surgeon has a high rate of cure in children and adults. Because of the poor prognosis associated with adrenal carcinoma, the guidelines highlight the need for complete resection and possibly medical treatment to stabilize cortisol levels.

Other first-line treatment options include recommending surgical resection of ectopic ACTH-secreting tumors; referring to an experienced pituitary surgeon for transsphenoidal selective adenomectomy; treatments to block hormone receptors in bilateral micronodular adrenal hyperplasia; and surgical removal in bilateral adrenal disorders.

The elevated mortality rate seen in patients with Cushing’s syndrome is due to infection, venous thrombosis and cardiovascular disease (CVD). Appropriately lowering cortisol levels improves hypertension, insulin resistance, dyslipidemia and obesity in patients with Cushing’s syndrome. Therefore, the guidelines highlight the need for restoring cortisol levels and treating the associated comorbidities.

Nevertheless, the task force specifically recommends against treatment without an established diagnosis or when there are no signs of Cushing’s syndrome and hypothalamic-pituitary-adrenal laboratory studies are borderline.

In patients who are not surgical candidates or in cases of noncurative resection, the decision on whether to consider second-line treatment options such as medical therapy, radiation, bilateral adrenalectomy or repeat transsphenoidal surgery should be based on several factors. For instance, the guidelines recommend taking into consideration location and size of the tumor, patient desires, goals of treatment and level of biochemical control.

The guidelines note medical therapy should be based on cost, efficacy and individualization of treatment. Endocrinologists can approach medical therapy with a goal of establishing normal cortisol levels or reducing cortisol levels to very low levels and replacing to achieve desired levels.

Remission in Cushing’s syndrome is associated with notable improvement; however, long-term follow-up is recommended for osteoporosis, CVD and psychiatric conditions.

After treatment, patients may experience reductions in weight, blood pressure, lipids and glucose levels that may allow reduction or discontinuation of medications. Even so, patients with a history of Cushing’s syndrome tend to have higher rates of hypertension, hyperlipidemia and diabetes. Likewise, rates of myocardial infarction are higher in this population, further emphasizing the need for treatment and management of diabetes and hypertension.

Sharpless highlighted that Cushing’s syndrome is rare.

“There are multiple studies that have shown that patients do better when they are treated in a specialty center where people see a lot of cases of this. So in that sense, treatment is not usually going to fall to the general practitioner,” she said.

She continued that the guidelines are helpful and provide guidance to endocrinologist who “can’t readily refer their patient to a pituitary center.”

Sharpless went on to describe the multidisciplinary care involved in Cushing’s syndrome including endocrinologists, neurosurgeons, radiologists, counselors and radiation oncologist.

“When the care is complicated, you want to ensure all of your providers have reviewed your case together and figured out the best plan.”

The guidelines were co-sponsored by the European Society of Endocrinology. Nieman received salary support for her work on the manuscript from the Intramural Research Program of the Eunice Kennedy Shiver Institute of Child Health and Human Development. Members of the task force reported multiple disclosures.
