Metoclopramide Can Mask Adrenal Insufficiency After Gland Removal in BMAH Patients

Metoclopramide, a gastrointestinal medicine, can increase cortisol levels after unilateral adrenalectomy — the surgical removal of one adrenal gland — and conceal adrenal insufficiency in bilateral macronodular adrenal hyperplasia (BMAH) patients, a case report suggests.

The study, “Retention of aberrant cortisol secretion in a patient with bilateral macronodular adrenal hyperplasia after unilateral adrenalectomy,” was published in Therapeutics and Clinical Risk Management.

BMAH is a subtype of adrenal Cushing’s syndrome, characterized by the formation of nodules and enlargement of both adrenal glands.

In this condition, the production of cortisol does not depend on adrenocorticotropic hormone (ACTH) stimulation, as usually is the case. Instead, cortisol production is triggered by a variety of stimuli, such as maintaining an upright posture, eating mixed meals — those that contain fats, proteins, and carbohydrates — or exposure to certain substances.

A possible treatment for this condition is unilateral adrenalectomy. However, after the procedure, some patients cannot produce adequate amounts of cortisol. That makes it important for clinicians to closely monitor the changes in cortisol levels after surgery.

Metoclopramide, a medicine that alleviates gastrointestinal symptoms and is often used during the postoperative period, has been reported to increase the cortisol levels of BMAH patients. However, the effects of metoclopramide on BMAH patients who underwent unilateral adrenalectomy are not clear.

Researchers in Japan described the case of a 61-year-old postmenopausal woman whose levels of cortisol remained high after surgery due to metoclopramide ingestion.

The patient was first examined because she had experienced high blood pressure, abnormal lipid levels in the blood, and osteoporosis for ten years. She also was pre-obese.

She was given medication to control blood pressure with no results. The lab tests showed high serum cortisol and undetectable levels of ACTH, suggesting adrenal Cushing’s syndrome.

Patients who have increased cortisol levels, but low levels of ACTH, often have poor communication between the hypothalamus, the pituitary, and the adrenal glands. These three glands — together known as the HPA axis — control the levels of cortisol in healthy people.

Imaging of the adrenal glands revealed they were both enlarged and presented nodules. The patient’s cortisol levels peaked after taking metoclopramide, and her serum cortisol varied significantly during the day while ACTH remained undetectable. These results led to the BMAH diagnosis.

The doctors performed unilateral adrenalectomy to control cortisol levels. The surgery was successful, and the doctors reduced the dose of glucocorticoid replacement therapy on day 6.

Eight days after the surgery, however, the patient showed decreased levels of fasting serum cortisol, which indicated adrenal insufficiency — when the adrenal glands are unable to produce enough cortisol.

The doctors noticed that metoclopramide was causing an increase in serum cortisol levels, which made them appear normal and masked the adrenal insufficiency.

They stopped metoclopramide treatment and started replacement therapy (hydrocortisone) to control the adrenal insufficiency. The patient was discharged 10 days after the surgery.

The serum cortisol levels were monitored on days 72 and 109 after surgery, and they remained lower than average. Therefore she could not stop hydrocortisone treatment.

The levels of ACTH remained undetectable, suggesting that the communication between the HPA axis had not been restored.

“Habitual use of metoclopramide might suppress the hypothalamus and pituitary via negative feedback due to cortisol excess, and lead to a delayed recovery of the HPA axis,” the researchers said.

Meanwhile, the patient’s weight decreased, and high blood pressure was controlled.

“Detailed surveillance of aberrant cortisol secretion responses on a challenge with exogenous stimuli […] is clinically important in BMAH patients,” the study concluded. “Caution is thus required for assessing the actual status of the HPA axis.”

Medical ID Jewelry Often Lacks Clear Instructions For Adrenal Insufficiency

Rushworth RL, et al. Clin Endocrinol. 2019;doi:10.1111/cen.13985.

Only 4.8% of patients with adrenal insufficiency who use medical identification jewelry clearly indicate on their emblem the need for urgent parenteral hydrocortisone in the event of an adrenal crisis, potentially jeopardizing the ability to receive proper assistance in an emergency, according to a cross-sectional analysis published in Clinical Endocrinology.

“Although the use of medical identification jewelry is recommended for patients with adrenal insufficiency to assist in the prevention and treatment of an adrenal crisis, the results of this study indicate that this advice is taken up by only a modest proportion of patients,” R. Louise Rushworth, MBBS, PhD, FAFPHM, an adjunct professor and medical epidemiologist at the School of Medicine, Sydney, and the University of Notre Dame Australia, told Endocrine Today. “Patients with secondary adrenal insufficiency have a lower uptake than those with primary adrenal insufficiency despite their risk of an adrenal crisis approaching that people with primary adrenal insufficiency.”

In a cross-sectional analysis, Rushworth and colleagues analyzed data from 1,955 patients with adrenal insufficiency aged at least 20 years with an active subscription to a large medical jewelry provider (MedicAlert) as of September 2018. The researchers calculated subscription rates by adrenal insufficiency subtype, geographic area, age and sex using relevant population data.

The overall subscription rate was 105.79 per million, representing approximately one-third of the estimated 300 per million patients with adrenal insufficiency in the population, according to researchers. Among subscribers, 57.4% had primary adrenal insufficiency and 15.1% had a diagnosis of congenital adrenal hyperplasia. The overall subscription rate for patients with primary adrenal insufficiency was 61.72 per million, or 61.7% of the approximately 100 per million patients with primary adrenal insufficiency in the Australian population, according to researchers.

Researchers observed considerable differences in subscription rates based on geographic region, patient age and sex. Western Australia had an overall subscription rate (247 per million) that was more than four times higher than Victoria, the state with the lowest subscription rate (60.87 per million; P < .0001). Patients aged 60 to 69 years had the highest subscription rate (165.15 per million), whereas patients aged 30 to 39 years had the lowest rate (47.23 per million; P < .001). Additionally, most subscribers reporting primary adrenal insufficiency were women (69%).

The researchers found that hydrocortisone was the most common replacement therapy (41.6%), followed by cortisone acetate (25.6%) and prednisone (16.3%). They noted that few patients — only 4.8% — clearly mentioned the need for urgent parenteral hydrocortisone in the event of severe illness.

Rushworth said most patients who used medical identification jewelry did not have clear emergency instructions inscribed on the emblem, and that this may lead to delays in administration of hydrocortisone in an emergency.

“Guidelines recommend that patients with adrenal insufficiency who are at risk for adrenal crisis should wear medical identification jewelry as a form of nonverbal communication in an emergency,” Rushworth said. “These should be recommended by the treating doctor, and adherence should be encouraged and reviewed regularly. The jewelry should be inscribed with clear instructions for emergency treatment, for example: ‘Adrenal insufficiency. Give IM 100 mg hydrocortisone.’” – by Regina Schaffer

Cortisol Pumps May Be Viable Option to Reduce Adrenal Crisis in Severe Adrenal Insufficiency

The use of an insulin pump to deliver continuous pulsatile cortisol may be a viable treatment option in patients with severe adrenal insufficiency who are unresponsive to oral corticosteroids, according to study results presented at the 28th Annual Congress of the American Association of Clinical Endocrinologists, held April 24 to 28, 2019, in Los Angeles, California.

According to the investigators, increasing oral steroid doses may be required to prevent adrenal crisis in patients with adrenal insufficiency. However, in light of the associated side effects of long-term use of steroids, an alternative treatment method is needed. Insulin pumps, typically used to treat patients with diabetes, can be used to deliver steroids and may provide symptom control, prevent adrenal crisis, and lower required corticosteroid dose.

The current study enrolled patients with adrenal insufficiency who could not absorb oral corticosteroid treatment or were not responding to treatment. Of 118 patients with adrenal insufficiency, 6 patients were switched to pump treatment.

The results indicated that the use of cortisol pumps was associated with a 78.5% risk reduction for adrenal crisis compared with oral corticosteroids. As hydrocortisone dose was gradually tapered using the cortisol pump, there was a mean dose reduction of 62.77 mg compared with oral corticosteroid therapy.

The researchers noted that in addition to reducing the number of adrenal crises, use of a cortisol pump was found to be associated with better symptom control and quality of life.

“Continuous pulsatile cortisol replacement via pump is an option for management of severe adrenal insufficiency in patients unresponsive to oral therapy,” concluded the researchers.

Health Alert: Adrenal Crisis Causes Death in Some People Who Were Treated with hGH

Doctors conducting the follow-up study of individuals treated with hGH looked at causes of death among recipients and found some disturbing news. Many more people have died from a treatable condition called adrenal crisis than from CJD (MaryO’Note: Creutzfeldt-Jakob Disease). This risk does not affect every recipient. It can affect those who lack other hormones in addition to growth hormone. Please read on to find out if this risk applies to you. Death from adrenal crisis can be prevented.

Adrenal crisis is a serious condition that can cause death in people who lack the pituitary hormone ACTH. ACTH is responsible for regulating the adrenal gland. Often, people are unaware that they lack this hormone and therefore do not know about their risk of adrenal crisis.

Most people who were treated with hGH did not make enough of their own growth hormone. Some of them lacked growth hormone because they had birth defects, tumors or other diseases that cause the pituitary gland to malfunction or shut down. People with those problems frequently lack other key hormones made by the pituitary gland, such as ACTH, which directs the adrenal gland to make cortisol, a hormone necessary for life. Having too little cortisol can be fatal if not properly treated.

Treatment with hGH does not cause adrenal crisis, but because a number of people lacking growth hormone also lack ACTH, adrenal crisis has occurred in some people who were treated with hGH. In earlier updates we have talked about how adrenal crisis can be prevented, but people continue to die from adrenal crisis, which is brought on by lack of cortisol. These deaths can be prevented. Please talk to your doctor about whether you are at risk for adrenal crisis.

  • Why should people treated with hGH know about adrenal crisis? Among the people who received hGH, those who had birth defects, tumors, and other diseases affecting the brain lacked hGH and often, other hormones made by the pituitary gland. A shortage of the hormones that regulate the adrenal glands can cause many health problems. It can also lead to death from adrenal crisis. This tragedy can be prevented.
  • What are adrenal hormones? The pituitary gland makes many hormones, including growth hormone and ACTH, a hormone which signals the adrenal glands to make cortisol, a hormone needed for life. If the adrenal gland doesn’t make enough cortisol, replacement medications must be taken. The most common medicines used for cortisol replacement are:
    • Hydrocortisone
    • Prednisone
    • Dexamethasone
  • What is adrenal crisis? Adrenal hormones are needed for life. The system that pumps blood through the body cannot work during times of physical stress, such as illness or injury, if there is a severe lack of cortisol (or its replacement). People who lack cortisol must take their cortisol replacement medication on a regular basis, and when they are sick or injured, they must take extra cortisol replacement to prevent adrenal crisis. When there is not enough cortisol, adrenal crisis can occur and may rapidly lead to death.
  • What are the symptoms of lack of adrenal hormones? If you don’t have enough cortisol or its replacement, you may have some of these problems:
    • feeling weak
    • feeling tired all the time
    • feeling sick to your stomach
    • vomiting
    • no appetite
    • weight loss

    When someone with adrenal gland problems has weakness, nausea, or vomiting, that person needs immediate emergency treatment to prevent adrenal crisis and possible death.

  • Why are adrenal hormones so important? Cortisol (or its replacement) helps the body respond to stress from infection, injury, or surgery. The normal adrenal gland responds to serious illness by making up to 10 times more cortisol than it usually makes. It automatically makes as much as the body needs. If you are taking a cortisol replacement drug because your body cannot make these hormones, you must increase the cortisol replacement drugs during times of illness, injury, or surgery. Some people make enough cortisol for times when they feel well, but not enough to meet greater needs when they are ill or injured. Those people might not need cortisol replacement every day but may need to take cortisol replacement medication when their body is under stress. Adrenal crisis is extremely serious and can cause death if not treated promptly. Discuss this problem with your doctor to help decide whether you need more medication or other treatment to protect your health.
  • How is adrenal crisis treated? People with adrenal crisis need immediate treatment. Any delay can cause death. When people with adrenal crisis are vomiting or unconscious and cannot take medicine, the hormones can be given as an injection. Getting an injection of adrenal hormones can save your life if you are in adrenal crisis. If you lack the ability to make cortisol naturally, you should carry a medical ID card and wear a Medic-Alert bracelet to tell emergency workers that you lack adrenal hormones and need treatment. This precaution can save your life if you are sick or injured.
  • How can I prevent adrenal crisis?
    • If you are always tired, feel weak, and have lost weight, ask your doctor if you might have a shortage of adrenal hormones.
    • If you take hydrocortisone, prednisone, or dexamethasone, learn how to increase the dose when you become ill.
    • If you are very ill, especially if you are vomiting and cannot take pills, seek emergency medical care immediately. Make sure you have a hydrocortisone injection with you at all times, and make sure that you and those around you (in case you’re not conscious) know how and when to administer the injection.
    • Carry a medical ID card and wear a bracelet telling emergency workers that you have adrenal insufficiency and need cortisol. This way, they can treat you right away if you are injured.

Remember: Some people who lacked growth hormone may also lack cortisol, a hormone necessary for life. Lack of cortisol can cause adrenal crisis, a preventable condition that can cause death if treated improperly. Deaths from adrenal crisis can be prevented if patients and their families recognize the condition and are careful to treat it right away. Adrenal crisis is a medical emergency. Know the symptoms and how to adjust your medication when you are ill. Taking these precautions can save your life.

Steroid Medication for Nasal Obstruction in Infants May Cause Cushing’s Syndrome

Intranasal steroid drops used to treat nasal obstruction may cause Cushing’s syndrome and adrenal insufficiency in infants, a case study of two patients suggests.

The study, “Iatrogenic Cushing’s syndrome and adrenal insufficiency in infants on intranasal dexamethasone drops for nasal obstruction – Case series and literature review,” was published in the International Journal of Pediatric Otorhinolaryngology.

Children with nasal obstruction may have severe delays in development and can face life-threatening complications later in life such as obstructive sleep apnea and cardiopulmonary problems.

While intranasal steroid drops have become increasingly popular as a substitute for surgery, they can have adverse effects. In addition to suppressing the immune system and changing metabolism, high levels of corticosteroids in the blood may cause Cushing’s syndrome.

Researchers at Weill Cornell Medical College presented two cases of adrenal gland insufficiency and Cushing’s syndrome caused by intranasal dexamethasone drops. Dexamethasone is a type of corticosteroid medication.

First, they described the case of a 3-month-old boy who was taken to the hospital following a life-threatening episode at home after feeding. A physical evaluation revealed nasal congestion with no additional anatomic abnormalities.

Treatment with nasal dexamethasone drops three times a day improved his breathing. While the dosage was later decreased to three drops once daily, a congestion episode led the mother to increase the dose back to the initial recommendation.

After seven weeks of treatment, the boy was noted to have facial puffiness, leading to an endocrine evaluation that revealed low cortisol levels. The dose was eventually reduced, and the boy’s cortisol levels returned to normal after several months.

The second case was a 6-week-old boy with a history of chronic congestion and difficulty feeding. He had severe nasal obstruction and required intubation due to respiratory distress. A nasal exam revealed damaged mucosa with severe nasal cavity narrowing, and he began treatment with three ciprofloxacin-dexamethasone drops three times a day.

After two and a half weeks of treatment, the boy’s cortisol levels were considerably low, and adrenal insufficiency was diagnosed. The treatment dose was reduced in an attempt to improve cortisol levels, but nasal obstruction symptoms continued.

The child then underwent surgery to resolve his nasal obstruction, and the treatment with steroid drops was discontinued. While his cortisol levels subsequently improved, they continued to be low, suggesting that he may have a hormone-related disease.

Despite the benefits of steroid-based nasal drops, small infants are more sensitive to steroid compounds. In addition, nasal drops are more easily absorbed than nasal sprays, suggesting that infants taking these medications should be better controlled for side effects.

“Patients started on this therapy must be closely monitored in a multi-disciplinary fashion to ensure patient safety and optimal symptom resolution,” the researchers suggested.
