Background: Primary adrenal insufficiency (PAI) in children is an uncommon, but potentially fatal. The current symptoms include weakness, fatigue, anorexia, abdominal pain, weight loss, orthostatic hypotension, salt craving and characterized by hyperpigmentation.

 

Material and Methods: This is a retrospective, hospital based-study, conducted at King Khalid University Hospital (KKUH), during the period January 1989 and December 2014. Review of medical record of patient diagnosed with primary adrenal insufficiency. The diagnosis was based on medical history, physical examination and low levels of glucocorticoids and raised adrenocorticotropic hormone (ACTH). Appropriate laboratory and radiological investigations were also reviewed.

 

Results: During the period under review, January 1989 and December 2014, a total of 125 patients with the diagnosis of primary adrenal insufficiency were seen. Inherited disorders like congenital adrenal hyperplasia and hypoplasia were common, 85.5%. However, variable autoimmune mediated etiologic diagnosis accounted for, 13%, were also seen. The appropriate various laboratory and radiological investigations should be planned.

 

Conclusion: Although, congenital adrenal hyperplasia was the commonest etiology, however, congenital adrenal hypoplasia should not be over looked. The diagnosis of PAI can be challenging in some patients, and therefore appropriate serological and radiological investigations should be done.

Topical Steroid Use in Psoriasis Patient Leads to Severe Adrenal Insufficiency

This article is written live from the American Association of Clinical Endocrinologists (AACE) 2017 Annual Meeting in Austin, TX. MPR will be reporting news on the latest findings from leading experts in endocrinology. Check back for more news from AACE 2017.

At the AACE 2017 Annual Meeting, lead study author Kaitlyn Steffensmeier, MS III, of the Dayton Veterans Affairs (VA) Medical Center, Dayton, OH, presented a case study describing a patient “who developed secondary adrenal insufficiency secondary to long-term topical steroid use and who with decreased topical steroid use recovered.”

The patient was a 63-year-old white male with a 23-year history of psoriasis. For 18 years, the patient had been applying Clobetasol Propionate 0.05% topically on several areas of his body every day. Upon presentation to the endocrine clinic for evaluation of his low serum cortisol, the patient complained of a 24-pound weight gain over a 2-year period, feeling fatigued, as well as facial puffiness.

Laboratory analysis found that the patient's random serum cortisol and ACTH levels were low (0.2µg/dL and <1 .1pg="" 2mm="" a="" according="" additionally="" adrenal="" authors="" cleft="" consistent="" cyst="" gland="" hypoenhancing="" indicative="" insufficiency.="" labs="" lesion="" microadenoma.="" midline="" ml="" mri="" nbsp="" of="" p="" pituitary="" rathke="" respectively="" s="" secondary="" showed="" study="" the="" to="" versus="" were="" with="" within="">

The patient was initiated on 10mg of hydrocortisone in the morning and 5mg in the evening and was instructed to decrease the use of his topical steroid to one time per month. For the treatment of his psoriasis, the patient was started on apremilast, a phosphodiesterase-4 enzyme (PDE4) inhibitor, and phototherapy.

After 2.5 years, the patient had a subnormal response to the cosyntropin stimulation test. However, after 3 years, a normal response with an increase in serum cortisol to 18.7µg/dL at 60 minutes was obtained; the patient was then discontinued on hydrocortisone. Additionally, a stable pituitary tumor was shown via a repeat pituitary MRI.

The study authors explained that, although secondary adrenal insufficiency is not commonly reported, “one study showed 40% of patients with abnormal cortisol response to exogenous ACTH after two weeks of topical glucocorticoids usage.” Another meta-analysis of 15 studies (n=320) revealed 4.7% of patients developing adrenal insufficiency after using topical steroids. Because of this, “clinicians need to be aware of potential side effects of prolong topical steroid use,” added the study authors.

Health Care Expenditure Burden High in Adrenal Insufficiency

Patients with adrenal insufficiency may accrue substantial health care costs and have more hospital stays and outpatient visits compared with healthy controls, according to findings published in the Journal of the Endocrine Society.

Candace Gunnarsson, PhD, vice president of health economics and outcomes research at CTI Clinical Trial and Consulting in Cincinnati, and colleagues evaluated data from a U.S.-based payer database on 10,383 patients with adrenal insufficiency to determine the estimated annual health care burden among them.

Participants were divided into groups based on their type of adrenal insufficiency: primary adrenal insufficiency (n = 1,014), adrenal insufficiency secondary to pituitary disease (n = 8,818) or congenital adrenal hyperplasia (n = 551). A group of matched controls was also evaluated for comparison.

Total annual health care expenditures were significantly higher in the primary adrenal insufficiency group ($18,624 vs. $4,320), adrenal insufficiency secondary to pituitary disease group ($32,218 vs. $6,956) and the congenital adrenal hyperplasia group ($7,677 vs. $4,203) compared with controls. The adrenal insufficiency secondary to pituitary disease group had the highest health care expenditure estimated with an incremental health care burden of $25,262, followed by the primary adrenal insufficiency group ($14,304) and the congenital adrenal hyperplasia group ($3,474).

Compared with controls, participants with adrenal insufficiency spent eight to 10 times more days in the hospital and had up to twice as many outpatient visits per year.

“When comparing [adrenal insufficiency] patients within each cohort based on their drug regimen, patients receiving prednisone therapy vs. hydrocortisone therapy had significantly higher total annual expenditures in the [primary adrenal insufficiency] and [congenital adrenal hyperplasia] and significantly lower total expenditures in the [pituitary disease] cohort,” the researchers wrote. “Patients taking only hydrocortisone and meeting the threshold of 50% adherence were found to have lower expenditures when medication adherence was 75% or higher.” – by Amber Cox

Adrenal Insufficiency Patients Require More Education on Adrenal Crisis

Greater efforts to educate patients with adrenal insufficiency and their families about prevention of adrenal crisis may be necessary, according to data presented at the American Association of Clinical Endocrinologists (AACE) 24th Annual Scientific & Clinical Congress.

Additionally, the researchers, who looked at patients treated for adrenal insufficiency, found that many are not being adequately trained or equipped to deal with an adrenal crisis.

“These patients can crash and we are not doing enough to help prevent problems,” study investigator Nitika Malhotra, MD, endocrinologist in Lansing, Michigan, said. “We did this study because we think this is a big problem.”

Malhotra, who presented the study findings at the meeting, explained that patients with adrenal insufficiency are at risk for developing adrenal crisis, and it is now estimated that 8% of patients with adrenal insufficiency are hospitalized for adrenal crisis each year.

The problem, according to Malhotra, is that far too many patients are failing to receive crises prevention education. Moreover, they are not receiving emergency glucocorticoid kits.

“All of the families need to be taught and that is not happening,” Malhotra said in an interview with Endocrinology Advisor. “It will reduce the morbidity and mortality and the hospitalization, and it may improve the quality of life of patients too.”

For their study, Malhotra and her colleagues collected data from patients with adrenal insufficiency who were seen at a single institution between March 2009 and March 2014.

The investigators conducted a retrospective chart review and examined age, gender, causes of adrenal insufficiency, glucocorticoid dose, and monitoring for hyponatremia and hyperkalemia. They also looked at postural blood pressure, crises prevention education for glucocorticoid dose adjustments during stress, and whether patients had a Medic Alert ID or a parenteral glucocorticoid kit. 

The researchers identified 85 patients (29 males and 56 females) with adrenal insufficiency. Of these patients, 33 patients had primary adrenal insufficiency (38.8%) and 52 had secondary adrenal insufficiency (61.2%). The mean age of the patients was 55.8 years.

Among the 85 patients, 23 (27%) had postural blood pressures checked — five of whom were positive (21.7%). Seventy-seven patients (90.6%) were monitored for electrolytes, and 41 patients (48.2%) were on steroid doses above 20 mg per day.  

However, the researchers found that only 57 patients (67.1%) had received steroid dose adjustment instructions. In addition, only 29 patients (34.1%) had a Medic Alert ID, and only 17 patients (20%) were setup with emergency parenteral glucocorticoid kits.

Even though this study has many inherent limitations, Malhotra said, it appears that the preventive strategies for adrenal crisis in patients with adrenal insufficiency are not being consistently followed.

Patient education is paramount for achieving a successful prevention strategy for adrenal crisis, and endocrinologists have a responsibility to make sure that all patients with adrenal insufficiency have a Medic Alert ID and access to emergency glucocorticoid kits, according to Malhotra.

Furthermore, she said families should receive adequate education about parenteral steroid administration and steroid dose adjustments in stressful situations.

At her institution, Malhotra said, endocrinologists are introducing an automated electronic alert in their electronic medical records to determine if this electronic prompt will improve adherence.

Addison's disease may cause psychosis, say researchers

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.

"An array of neuropsychiatric symptoms is associated with AD. Addison is quoted as saying in 1855 that AD patients might present with “attacks of giddiness, anxiety in the face, and delirium.”1 Anglin et al1 also noted four case series published in the 1940s and 1950s that found the prevalence of neuropsychiatric symptoms in AD to be between 64 and 84 percent. Iwata et al6 reported that in some cases, the neuropsychiatric symptoms were the initial and sole presentation of AD, even though such symptoms are more common in the late course of the disease; this might lead to a patient initially being misdiagnosed, as it did in our case, and in turn, incorrectly treated. Neuropsychiatric symptoms of AD include, but are not limited to, depression, lack of energy, and sleep disturbances. During an Addisonian crisis, agitation, delirium, and, in some cases, visual and auditory hallucinations are reported.1 According to Smart,7 neuropsychiatric symptoms might also be the first presentation of an Addisonian crisis, especially in a patient who was previously symptom free while under therapy."

It is not clear exactly why these neuropsychiatric symptoms appear. It is possible that electrolytic and metabolic disturbances could produce these symptoms, and hyponatremia, which is its central expression, can result in brain damage. Other researchers believe that the neuropsychiatric symptoms are the effects of glucocorticoid abnormalities on the brain. Some researchers believe that unusually low amounts of the substance could produce hallucinations. In one report, Addison's disease presented as a psychotic break:

"A Caucasian 63-year-old man presented a five-month history of progressive depressive symptoms with sadness, anhedonia, asthenia, hyporexia, insomnia, limb weakness, and psychotic symptoms. He was a former heavy smoker and had been diagnosed with chronic occupational lung disease (silicosis). After a specialized psychiatric consultation, the patient started taking fluoxetine, risperidone, and nitrazepam. After a short period of time, the patient withdrew his medication by his own because of worsening of the limb weakness. The patient became severely paranoid with persecutory beliefs, delusions, an infantile speech, progressive social isolation, fear of leaving his home, periods of mental confusion and disorientation, and sporadic nausea and vomits. A few days before hospital admission, the patient almost stopped fluid intake and evolved with syncope."

New Jersey Ambulances Carrying Solu-Cortef

The New Jersey Department of Health passed a waiver in October of last year that allows ambulances to carry Solu- Cortef, for the purposes of treating an adrenal crisis. As a result, New Jersey ambulances can be better prepared to treat adrenal insufficiency.

This news was brought to NADF by Karen Fountain of the CARES Foundation, who has been helping push state health directors to accept protocols to help treat adrenal insufficient patients during an emergency.

Adrenal insufficient people in New Jersey should contact their local EMS to make them aware of the waiver, and encourage them to carry Solu-Cortef in their ambulances.

The hope is that other states, and eventually the entire country and beyond, will start having their ambulances carry the needed medication to treat adrenal crisis.

Abstract

BACKGROUND:

Conventional glucocorticoid (GC) replacement for patients with adrenal insufficiency (AI) is inadequate. Patients with AI continue to have increased mortality and morbidity and compromised quality of life despite treatment and monitoring.

OBJECTIVES:

i) To review current management of AI and the unmet medical need based on literature and treatment experience and ii) to offer practical advice for managing AI in specific clinical situations.

METHODS:

The review considers the most urgent questions endocrinologists face in managing AI and presents generalised patient cases with suggested strategies for treatment.

RESULTS:

Optimisation and individualisation of GC replacement remain a challenge because available therapies do not mimic physiological cortisol patterns. While increased mortality and morbidity appear related to inadequate GC replacement, there are no objective measures to guide dose selection and optimisation. Physicians must rely on experience to recognise the clinical signs, which are not unique to AI, of inadequate treatment. The increased demand for corticosteroids during periods of stress can result in a life-threatening adrenal crisis (AC) in a patient with AI. Education is paramount for patients and their caregivers to anticipate, recognise and provide proper early treatment to prevent or reduce the occurrence of ACs.

CONCLUSIONS:

This review highlights and offers suggestions to address the challenges endocrinologists encounter in treating patients with AI. New preparations are being developed to better mimic normal physiological cortisol levels with convenient, once-daily dosing which may improve treatment outcomes.

FDA Puts Strict Limits on Oral Ketoconazole Use

By John Gever, Deputy Managing Editor, MedPage Today

SILVER SPRING, Md. -- Oral ketoconazole (Nizoral) should never be used as first-line therapy for any type of fungal infection because of the risk of liver toxicity and interactions with other drugs, the FDA said Friday.

The agency ordered a series of label changes and a new medication guide for patients that emphasize the risks, which also include adrenal insufficiency. It noted that the restrictions apply only to the oral formulation, not topical versions.

Late Thursday, the chief advisory body for the FDA's European counterpart went further. The EU's Committee on Medicinal Products for Human Use (CHMP) recommended that member nations pull oral ketoconazole from their markets entirely.

Both the FDA and the CHMP cited studies indicating high risks of severe, acute liver injury in patients taking the drug. Studies using the FDA's adverse event reporting system and a similar database in the U.K. indicated that liver toxicity was more common with oral ketoconazole than with other anti-fungals in the azole class.

The FDA also said that oral ketoconazole "is one of the most potent inhibitors" of the CYP3A4 enzyme. This effect can lead to sometimes life-threatening interactions with other drugs metabolized by CYP3A4, and also to adrenal insufficiency, since the enzyme also catalyzes release of adrenal steroid hormones.

"This accounts for clinically important endocrinologic abnormalities observed in some patients (particularly when the drug is administered at high dosages), including gynecomastia in men and menstrual irregularities in women," the FDA said.

The only indication for oral ketoconazole still supported by the FDA is for use in life-threatening mycoses in patients who cannot tolerate other anti-fungal medications or when such medications are unavailable.

In such instances, the FDA said, physicians should assess liver function before starting the drug. It is contraindicated in patients with pre-existing liver disease, and patients should be instructed not to drink alcohol or use other potentially hepatotoxic drugs.

Adrenal function should also be monitored in patients using the drug.

The CHMP also indicated the topical formulations of ketoconazole should stay on the market, but it found no basis for keeping the oral form available for any purpose.

"Taking into account the increased rate of liver injury and the availability of alternative anti-fungal treatments, the CHMP concluded that the benefits did not outweigh the risks," the panel indicated in a statement.

It recommended that physicians stop prescribing oral ketoconazole and that they should review alternatives in patients currently receiving the drug. The committee also said that patients now taking oral ketoconazole "make a non-urgent appointment" with their physicians to discuss their treatment.

Adrenal Insufficiency - Female Patient found Unconscious with Syringe Nearby

Crew’s misdiagnosis of drug overdose could have cost patient her life

Kimberly Doran | From the October 2012 Issue |

A call comes in to 9-1-1 dispatch. “Help” is all that’s spoken before the operator hears the phone hit the floor. The 9-1-1 dispatcher calls back only to get a busy signal. Police and EMS are dispatched for a well-being call.

On arrival, the front door is found to be slightly ajar. The crew knocks, but there’s no reply. They find a young woman  lying on the floor, naked, and in a pool of vomit. A syringe with an unknown substance is on the ground nearby. Suspecting a drug overdose, the EMS crew begins treating the patient for this condition. The patient is unconscious with emesis around her head and face. Her vital signs are blood pressure 60/45, heart rate of 130 bpm and respiratory rate of 10.

The patient shows no signs of waking. The crew clears the airway and administers oxygen. An IV is established, and the patient is readied for transport. As the crew leaves the scene, one of the medics turns to shut the door and sees a vial under a chair. He retrieves it and notes that the label says Solu-Cortef (a glucocorticoid). He bags it for the emergency department (ED). Following his instinct, he looks around the area for medications and finds two bottles. One is labeled dexamethosone and the other is labeled fludrocortisone. He takes his findings and rushes out the door into the awaiting ambulance. During transport, the patient continues to deteriorate.

The medic administers 0.5 mg of narcan and a 500mL bolus of normal saline with no response. He radios ahead to let the hospital know that they’re en route. Now questioning the original diagnosis of drug overdose, he reports the medications he found on the scene in hopes it will help the receiving physician determine the cause of the patient’s condition.

Arrival at the ED
On arrival to the ED, the medic hands over the loaded syringe containing 2mL of unidentified solution, as well as the empty vial of Solu-Cortef and the bottles of dexamethosone and fludrocortisones.

As the crew arrives at the hospital, the ED physician meets the crew and informs them that he’s familiar with the medications. He says they're all used for people who have various forms of adrenal insufficiency (AI). The symptoms seen in this patient coincide with life-threatening adrenal crisis. The physician administers 100 mg of Solu-Cortef via IV and within minutes, the patient rouses. In 30 minutes, she can explain what happened in the desperate moments before her crisis.

Adrenal Insufficiency
Adrenal Insufficiency (AI) is a life-threatening in which the body is unable to produce enough cortisol to sustain life. In other words, their adrenal cortex is “asleep.” People suffering from AI take daily cortisol/glucocorticoid steroid replacement because whatever adrenal function is depleted. These patients are glucocorticoid dependent. In times of injury, dehydration, illness or surgery, they require an injection of Solu-Cortef. Solu-Cortef contains both glucocorticoid and mineralocorticoid properties, helping the body to compensate during a stress event.

The adrenal medulla (inside of the adrenal gland) secretes epinephrine and norepinephrine. The adrenal cortex (outer layer of the adrenal gland) secretes cortisol and aldosterone. Cortisol, a glucocorticoid, is often called the “stress” hormone. One of cortisol's functions is elevating blood glucose levels in times of stress. It also functions as a mediator for several inflammatory pathways.

Absence of cortisol can result in hypotension, hypoglycemia and death. Aldosterone, a mineralocorticoid, is responsible for the regulation of sodium and water. Absence of aldosterone can result in hypotension and electrolyte imbalance. AI in the prehospital setting may be difficult to recognize in the absence of a good history, including medications, to point providers in the cause of the problem. Two life-threatening conditions associated with AI include hypotension and hypoglycemia.

If not managed, these two conditions are life threatening. Prehospital treatment should include management of the patient’s airway, vascular access and fluid resuscitation. If blood glucose levels are low, the patient should receive dextrose per local protocol. It’s important to complete a thorough physical assessment and obtain a complete patient history before treating patients with this condition. Providers may confuse patients having an adrenal crisis with drug overdose patients because of their similar symptoms. Although AI is rare, it should still be considered as a potential diagnosis.

Authors’ note: Parts of the above case are taken from a true story. However, the difference is that there was no syringe on the floor, no vial under the chair and no one found the medications. The patient was treated with charcoal and diagnosed as a drug-overdose patient. She likely would have died, but her mother charged into the ED and expressed the need for Solu-Cortef. Security was called, but luckily someone listened, researched and called the patient’s treating physician. The patient was treated and released.

Adrenal cavernous hemangioma with subclinical Cushing’s syndrome: report of a case

Cavernous hemangioma of the adrenal gland is a rare tumor, which does not usually have endocrinological function. We report to our knowledge, the third documented case of a functioning adrenal hemangioma.

Interestingly, this tumor indicated glucocorticoid hypersecretion, whereas the two previous cases showed mineralocorticoid hypersecretion. The tumor was 5 cm in diameter with typical computed tomography and magnetic resonance imaging findings.

Subclinical Cushing’s syndrome was diagnosed preoperatively, as there was insufficient suppression of cortisol by low-dose dexamethasone, a low adrenocorticotropic hormone (ACTH) concentration, and diminished ACTH and cortisol circadian rhythms without the typical clinical manifestation and symptoms of hypercortisolism.

Intraoperative hypotension occurred immediately after tumor removal and following postoperative adrenal insufficiency, which support that the tumor was hyperfunctioning. The postoperative adrenal insufficiency had recovered completely by 12 months after the operation.

Abstract Summary

Primary adrenal insufficiency is treated with glucocorticoid and mineralocorticoid replacement therapy. Recent data revealed that health-related quality of life in adrenal insufficiency is impaired in many patients and that patients with adrenal insufficiency are also threatened by an increased mortality and morbidity. This may be caused by inadequate glucocortiocid therapy and adrenal crisis. Therefore, the optimization of hormone replacement therapy remains one of the most challenging tasks in endocrinology because it is largely based on clinical grounds because of the lack of objective assessment tools.

This article provides answers to the important daily clinical questions, such as correct dose finding, dose adaptation in special situations, e g, pregnancy, improvement of quality of life and measures for protection from adrenal crisis. Other important aspects discussed are side effects of glucocortiocid replacement therapy and interactions with other drugs.

DuoCort Pharma's Orphan Drug Plenadren® Granted European Marketing Authorization for Adrenal Insufficiency

HELSINGBORG, Sweden and EXTON, Pa., Nov. 7, 2011 /PRNewswire/ -- The Swedish specialty pharma company, DuoCort Pharma, announced today that the European Commission has granted a European Marketing Authorisation for Plenadren®(hydrocortisone, modified release tablet), an orphan drug for treatment of adrenal insufficiency in adults,  bringing these patients their first pharmaceutical innovation in over 50 years.

Developed by DuoCort Pharma, Plenadren® is a dual release hydrocortisone replacement therapy designed to better mimic the normal physiological cortisol profile in order to improve outcomes for patients suffering from adrenal insufficiency. Plenadren® is given as an oral tablet once daily.  It has an outer layer releasing hydrocortisone immediately and an inner core releasing the rest of the drug more slowly during the day.

Although glucocorticoid hormone replacement therapy for adrenal insufficiency has been available for decades, studies have recorded complications and comorbidities including premature death, impaired quality of life, increased risk of cardiovascular diseases, and decreased bone mineral density in treated patients, most likely because it is difficult to match the natural secretion pattern of cortisol.  

Maria Forss, CEO of DuoCort Pharma, said: "The marketing authorization for Plenadren® in Europe is an important step towards addressing the unmet needs of these patients."    

The approval of Plenadren® follows the positive opinion adopted by the Committee for Medicinal Products for Human Use (CHMP) in July 2011. Plenadren® is now approved for marketing in all countries of the European Union (EU) as well as in the European Economic Area (EEA), namely Iceland, Norway and Lichtenstein.  

Professor Gudmundur Johannsson of the Department of Endocrinology, Sahlgrenska University Hospital, Gothenburg, Sweden, and Chief Medical Officer of DuoCort Pharma, said: "Plenadren® offers a welcome new treatment option to help patients suffering from adrenal insufficiency. Plenadren® can improve therapy for many of the almost 200,000 patients in Europe who suffer from this disease and who need life-long cortisol replacement therapy for their survival."

On October 26, 2011, ViroPharma Incorporated (NASDAQ: VPHM) signed a definitive agreement to acquire DuoCort Pharma AB.  The companies expect to complete the acquisition in November 2011. On closing, ViroPharma will pay an upfront closing cost of 220 million Swedish kroner (SEK) or $33 million in US dollars (USD).  Additionally, there are contingent milestone payments of up to 860 million SEK or $130 million USD associated with manufacturing, sales thresholds and territory expansion.  

About Adrenal insufficiency

Adrenal insufficiency (cortisol deficiency) is a rare, life-threatening disease that affects patients in their active years. To survive, patients suffering from this disease need lifelong replacement therapy with hydrocortisone. Treatment of adrenal insufficiency involves replacing, or substituting, the hormones that the patient's own adrenal glands are not producing. Cortisol is replaced using hydrocortisone, the synthetic form of cortisol.

About Plenadren® (hydrocortisone, modified release tablet)

Plenadren is the first true innovation in over 50 years in the treatment of adrenal insufficiency.

Hypersensitivity to the active substance of Plenadren or to any of the excipients may occur.  During acute adrenal insufficiency, parenteral administration of hydrocortisone in high doses, together with physiological sodium chloride solution for injection, must be given.  Use of Plenadren with potent CYP 3A4 inducers and inhibitors may merit an adjustment of hydrocortisone dosage.  High (supra-physiological) dosages of cortisone can cause elevation of blood pressure, salt and water retention, and increased excretion of potassium.  Long-term treatment with higher than physiological hydrocortisone doses can lead to clinical features resembling Cushing's syndrome with increased adiposity, abdominal obesity, hypertension and diabetes, and thus result in an increased risk of cardiovascular morbidity and mortality. All glucocorticoids increase calcium excretion and reduce the bone remodeling rate.  Patients with adrenal insufficiency on long term glucocorticoid replacement therapy have been found to have reduced bone mineral density.  Psychiatric adverse events may occur with systemic glucocorticoids.

The most common adverse reactions observed in clinical studies have been fatigue, gastroenteritis, upper respiratory tract infection, sedation, vertigo and dry eyes.

Benign adrenal gland tumors.

Case

A 54-year-old man with a history of hypertension treated with hydrocholorothiazide and Type 2 diabetes mellitus is admitted with abdominal pain and found to have an incidental 2.1-cm left adrenal mass on CT scan of the abdomen. He denies symptoms of headache, palpitations, weight gain, or muscle weakness. His exam is significant for mildly elevated blood pressure. What is the best approach for evaluation and management of this incidental finding?

Overview

Incidentalomas are mass lesions that are inadvertently discovered during radiolographic diagnostic testing or treatment for other clinical conditions that are unrelated to the incidental mass. In recent decades, improvements in radiographic diagnostic techniques and sensitivity have led to increasing discovery of incidental lesions that are often in the absence of clinical signs or symptoms.¹ Three commonly discovered lesions by hospitalists are pituitary, thyroid, and adrenal incidentalomas.² The concerns associated with these findings relate to the potential for dysfunctional hormone secretion or malignancy.

Patients found with pituitary incidentalomas can be susceptible to several types of adverse outcomes: hormonal hypersecretion, hypopituitarism, neurologic morbidity due to tumor size, and malignancy in rare cases. Thyroid incidentalomas are impalpable nodules discovered in the setting of ultrasound or cross-sectional neck scans, such as positron emission tomography (PET) scans. Discovery of a thyroid incidentaloma raises concern for thyroid malignancy.³ The increased use of abdominal ultrasound, CT scans, and MRI has fueled the growing incidence of adrenal incidentalomas (AIs).

The discovery of an endocrine incidentaloma in the inpatient setting warrants a systematic approach that includes both diagnostic and potentially therapeutic management. A hospitalist should consider an approach that includes (see Table 1):

1. Characterization of the incidentaloma, including clinical signs and symptoms, size, hormonal function, and malignant potential;
2. Immediate management, including medical versus surgical treatment; and
3. Post-discharge management, including monitoring.

Review of the Data

Pituitary incidentalomas. The prevalence of pituitary incidentalomas found by CT ranges from 3.7% to 20%, while the prevalence found by MRI approximates 10%. Autopsy studies have revealed a prevalence ranging from 1.5% to 26.7% for adenomas less than 10 mm, considered to be microadenomas. Broad categories of etiologies should be considered: pituitary adenoma, nonpituitary tumors, vascular lesions, infiltrative disorders, and others (see Table 2). The majority of pituitary adenomas secrete prolactin (30% to 40%) or are nonsecreting (30% to 40%). Adenomas secreting adrenocorticotropin hormone (ACTH, 2% to 10%), growth hormone (GH, 2% to 10%), thyroid-stimulating hormone (TSH, <1%), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) are much less common.2 Significant morbidity and premature mortality are associated with hyperprolactinemia, acromegaly (growth hormone excess), Cushing’s syndrome, and hyperthyroidism. Additionally, up to 41% of patients with macroadenomas were found to have varying degrees of hypopituitarism due to compression of the hypothalamus, the hypothalamic-pituitary stalk, or the pituitary itself.⁴

TABLE 2. DIFFERENTIAL DIAGNOSIS FOR PITUITARY INCIDENTALOMAS^2,4,14

Pituitary adenoma:

• Secreting: prolactin, growth hormone, ACTH, glycopeptides (LH, FSH, TSH, a-subunit)
• Nonsecreting

Non-pituitary tumors:

• Germ cell tumors
• Craniopharyngioma
• Meningioma
• Metastatic disease

Vascular lesions:

• Aneurysms
• Hamartomas
• Infarctions

Infiltrative:

• Sarcoidosis
• Histiocytosis
• Lymphocytic hypophysitis
• Eosinophilic granulomas

Other:

• Rathke’s cleft cyst
• Anatomic abnormalities

ACTH=adrenocorticotropin hormone, GH=growth hormone, TSH=thyroid-stimulating hormone (thyrotropin), LH=luteinizing hormone, FSH=follicle-stimulating hormone

Recently, the Endocrine Society released consensus recommendations to guide the evaluation and treatment of pituitary incidentalomas, which are included in the approach outlined below.⁵ A detailed history and physical examination should be obtained with specific inquiry as to signs and symptoms of hormonal excess and mass effect from the tumor. Examples of symptoms of hormone excess can include:

• Prolactin: menstrual irregularity, anovulation, infertility, decreased libido, impotence, osteoporosis;
• Growth hormone: high frequency of colonic polyps and colon cancer (chronic excess);
• TSH: thyrotoxicosis, atrial fibrillation; and
• ACTH: hypertension, osteoporosis, accelerated vascular disease.

Symptoms related to the mass effect of the tumor include visual field defects and hypopituitarism related to the deficient hormone, including:

• FSH/LH: oligomenorrhea, decreased libido, infertility;
• TSH: hypothyroidism (weight gain, constipation, cold intolerance);
• ACTH: adrenal insufficiency (hypotension, hypoglycemia, weight loss); and
• ADH: polyuria, polydypsia.

The size and location of the pituitary lesion must be assessed. Lesions greater than 10 mm are considered macroademonas, and their size will affect their management. If the lesion was initially identified by CT scan, an MRI is recommended to better evaluate it.⁵ If the MRI locates the incidentaloma abutting the optic nerve or chiasm, then the patient should undergo a formal visual field examination.

Indications for an inpatient surgical referral for treatment include: a lesion larger than 2 cm, evidence of mass effect such as visual field defects, neurologic compromise, opthalmoplegia, hypopituitarism, a tumor abutting the optic nerve or chiasm, pituitary apoplexy, and hypersecretion of hormones other than prolactin. Patients with prolactinomas warrant an inpatient endo-crinology consult and may need medical management with a dopamine agonist. Hormone replacement therapy can also be provided for patients with hypopituitarism.^2,5

For patients who do not meet the criteria for inpatient surgical therapy, follow-up management must be arranged at the time of discharge. Clinical, laboratory assessment, and an MRI should be scheduled six months after the initial finding of the incidentaloma with the patient’s PCP or with an endocrinologist.⁵

Thyroid incidentalomas. The prevalence of thyroid nodules based on ultrasound studies ranges from 19% to 46%, with autopsy studies estimating an incidence of approximately 50%.^2,6 Incidence of thyroid nodules also increases with age, as almost 60% of people over the age of 60 harbor a thyroid incidentaloma. The rate of malignancy in the general population has ranged between 8% and 24%; however, in the last decade, the rates have increased by 2.4 times as more sophisticated ultrasound techniques and liberal use of fine-needle aspiration (FNA) biopsies have detected subclinical disease.^7,8

Etiologies for incidental thyroid nodules can be divided into benign and malignant causes. Benign etiologies include thyroid cyst (simple or complex), multinodular goiter, and Hashimoto’s thryoiditis, while malignant causes include papillary, medullary, follicular, Hurthle cell, and anaplastic carcinomas, thyroid lymphomas, and rare instances of metastatic cancers.^2,3

Targeted history and physical examination helps to characterize the thyroid incidentaloma. Historical features, such as palpitations, weight loss, anxiety, new onset atrial fibrillation, or menstrual irregularities, coupled with tachycardia, tremors, proximal muscle weakness, and a palpable nodule aid in the diagnosis of hyperthyroidism. Findings such as a family history of thyroid cancer, symptoms of hoarseness or dysphagia, rapid growth of the nodule, environmental or history of head or neck irradiation along with physical findings of a hard, fixed nodule, or cervical lymphadenopathy increase the suspicion for malignancy.^2,7

The functionality of the nodule can be assessed by checking TSH, free T3, and free T4 levels. Suppression of TSH (< 0.1 mU/L) with elevated levels of free T3 and T4 indicates nodule production of excess thyroid hormone and warrants thyroid scintography. Thyroid scintography will identify the nodule as “hot” (hyperfunctioning) or “cold” (nonfunctioning).²

Regardless of the radiographic modality that initially identified the thyroid incidentaloma, a dedicated thyroid high-resolution ultrasound should be ordered to assess the size, multiplicity (single or multinodular), location, and character (solid, cystic, or mixed).⁷

Recommendations for proceeding to FNA to evaluate for malignancy differ among subspecialty societies. Generally, nodules larger than 1 cm or nodules smaller than 1 cm with risk factors for malignancy should be referred for FNA.^2,7

If diagnostic workup identifies a patient with hyperthyroidism due to an autonomously functional nodule or a nodule that may be at high risk for malignancy, it is appropriate to involve an endocrinologist and possibly a surgical subspecialist prior to discharge. Management of hyperthyroidism can include starting antithyroid agents (methimazole or propylthiouracil), radioactive iodine ablation, or referral for surgery.

Preparation for discharge of the patient whose incidentaloma is nonfunctional or does not appear to be malignant should include appointments to recheck thyroid hormone levels, including TSH as well as a thyroid ultrasound within one year of the initial discovery.

Adrenal incidentaloma. The prevalence of AIs found by CT of the abdomen ranges from 0.4% to 4%, while autopsy studies have found a prevalence of 1.4% to 9% with increasing prevalence with age.^2,9,10 The majority of AIs are benign and nonfunctioning adenomas, in the absence of known malignancy. Other differential diagnoses include Cushing’s syndrome, pheochromocytoma, adrenocortical adenoma, aldosteronoma, and metastatic lesions.

Because functioning adrenal incidentalomas may be clinically silent, any patient found with an AI must undergo biochemical workup as part of their evaluation to assess for pheochromocytoma, Cushing’s syndrome, and if he or she has a history of hypertension or hyperaldosteronism (Conn’s syndrome). Table 3 outlines the approach for characterizing adrenal incidentalomas.^2,11,12 An important point is that imaging studies are not useful in distinguishing a functioning versus nonfunctioning tumor but rather can help to discriminate malignant lesions.¹¹

click for large version

Table 3. Characterization of the adrenal incidentaloma^2,11

Inpatient surgical consult for resection is indicated if the patient is found to have pheochromocytoma, clinically apparent functioning adrenocortical adenoma, or a tumor size greater than 4 cm. Consultation with an endocrinologist is also recommended if biochemical tests are positive. If the diagnostic workup leads to suspicion for infection or metastatic disease, the patient should be referred for FNA.^2,12

For patients whose lesions do not require surgical resection, repeat CT scan of the abdomen is recommended six months from the initial finding. Hospitalists should also arrange for the patient to repeat biochemical testing, including an overnight dexamethasone test.^12,13

Back to the Case

The patient underwent biochemical testing and was found to have normal levels of plasma-free metanephrines, a plasma aldosterone, plasma renin activity ratio less than 20, and a serum cortisol level of 7 mg/dL after his overnight dexamethasone suppression test. The 24-hour urine collection for free cortisol revealed elevated levels of cortisol in the urine, and the ACTH level was low.

Endocrinology and endocrine surgery teams were consulted, and recommended surgical resection. After surgical resection of his tumor, the patient was started on glucocorticoid replacement and was discharged with a follow-up appointment with endocrinology.

Bottom Line

An inpatient approach to endocrine incidentalomas should include characterization of the clinical signs and symptoms, size, function, and malignant potential of the lesion. Based on this, inpatient surgical or medical management can be determined. Post-discharge management should include arrangements for surveillance testing and follow-up with appropriate subspecialists.
