Summary

Chronic exposure to excess glucorticoids results in diverse manifestations of Cushing’s syndrome, including debilitating morbidities and increased mortality.

Genetic and molecular mechanisms responsible for excess cortisol secretion by primary adrenal lesions and adrenocorticotropic hormone (ACTH) secretion from corticotroph or ectopic tumours have been identified. New biochemical and imaging diagnostic approaches and progress in surgical and radiotherapy techniques have improved the management of patients.

The therapeutic goal is to normalise tissue exposure to cortisol to reverse increased morbidity and mortality. Optimum treatment consisting of selective and complete resection of the causative tumour is necessay to allow eventual normalisation of the hypothalamic-pituitary-adrenal axis, maintenance of pituitary function, and avoidance of tumour recurrence. The development of new drugs offers clinicians several choices to treat patients with residual cortisol excess.

However, for patients affected by this challenging syndrome, the long-term effects and comorbidities associated with hypercortisolism need ongoing care.

If One Partner Has Cushing’s Syndrome, Can The Couple Still Get Pregnant?

Posted on May 12, 2015 by MaryO

Cushing’s syndrome can affect fertility in both men and women.

Women

The high levels of cortisol in Cushing’s syndrome disrupt a woman’s ovaries. Her menstrual periods may stop completely or become irregular. As a result, women with Cushing’s syndrome almost always have difficulty becoming pregnant.5,6,7 For those who do become pregnant, the risk of miscarriage is high.5,6,7

In rare cases, usually when a woman’s Cushing’s syndrome is caused by a benign adrenal tumor, pregnancy can occur, but it brings high risk for the mother and fetus.5,6,7

After a woman is treated for Cushing’s syndrome, her ovaries often recover from the effects of too much cortisol. Her regular menstrual cycles will return, and she can become pregnant.8

In some women, regular periods do not return after they are treated for Cushing’s syndrome. This occurs if surgery removes the part of the pituitary gland involved in reproduction.4 An infertility specialist can prescribe hormone therapy to bring back regular periods, ovulation, and fertility.8

Men

A man diagnosed with Cushing’s syndrome may have a decline in sperm production and could have reduced fertility.9 He also might experience a lowered sex drive as well as impotence (pronounced IM-puh-tuhns). In addition, some medications used to treat Cushing’s syndrome can reduce fertility.10 However, fertility usually recovers after Cushing’s syndrome is cured and treatment has stopped.9

Does Cushing’s syndrome affect pregnancy?

Cushing’s syndrome can cause serious and potentially life-threatening effects for the mother and the fetus during pregnancy.11,12 For example, Cushing’s syndrome raises a woman’s risk of developing pregnancy-related high blood pressure (called preeclampsia, pronounced pree-i-KLAMP-see-uh, or eclampsia) and/or pregnancy diabetes, which also is called gestational (pronounced je-STEY-shuhn-ul) diabetes). Infection and slow healing of any wounds are more likely, as is heart failure. When the syndrome is caused by a tumor, it will be surgically removed as early as possible to reduce any threat.13

Congenital adrenal hyperplasia: Current surgical management at academic medical centers in the United States

Posted on April 29, 2015 by MaryO

J Urol. 2015 May;193(5 Suppl):1796-801. doi: 10.1016/j.juro.2014.11.008. Epub 2015 Mar 25.

Congenital adrenal hyperplasia: current surgical management at academic medical centers in the United States.

Abstract

PURPOSE:

Controversy exists on the necessity for and timing of genitoplasty in girls with congenital adrenal hyperplasia. Our knowledge of surgical preferences is limited to retrospective series from single institutions and physician surveys, which suggest a high rate of early reconstruction. We evaluated current surgical treatment for congenital adrenal hyperplasia at academic centers.

MATERIALS AND METHODS:

We queried the Faculty Practice Solutions Center database to identify all female patients younger than 18 years with a diagnosis of congenital adrenal hyperplasia between 2009 and 2012. Procedures were identified by CPT codes for vaginoplasty, clitoroplasty and other genital procedures. Reconstruction type, age at surgery and surgeon volume were analyzed.

RESULTS:

We identified 2,614 females in the database with a diagnosis of congenital adrenal hyperplasia who were seen at a total of 60 institutions. Of infants younger than 12 months between 2009 and 2011 as few as 18% proceeded to surgery within a 1 to 4-year followup. Of those referred to a pediatric urologist 46% proceeded to surgery. Of patients who underwent surgery before age 2 years clitoroplasty and vaginoplasty were performed in 73% and 89%, respectively, while 68% were treated with a combined procedure. A medium or high volume surgeon was involved in 63% of cases.

CONCLUSIONS:

Many patients with congenital adrenal hyperplasia in the database did not proceed to early reconstructive surgery. Of those referred to surgeons, who were possibly the most virilized patients, about half proceeded to early surgery and almost all underwent vaginoplasty as a component of surgery. About two-thirds of the procedures were performed by medium or high volume surgeons, indicative of the surgical centralization of disorders of sexual development.

Common Asthma Steroids Linked to Side Effects in Adrenal Glands

Posted on April 25, 2015 by MaryO

(Reuters Health) – After stopping steroids commonly prescribed for asthma and allergies, a significant number of people may experience signs of malfunctioning in the adrenal glands, a European study finds.

So-called adrenal insufficiency can be dangerous, especially if the person’s body has to cope with a stress like surgery, injury or a serious illness, the study authors say.

“The takeaway message of the study is that in corticosteroid use there is a substantial risk of adrenal insufficiency,” senior author Dr. Olaf Dekkers, an endocrinologist at Aarhus University in Denmark, said by email. “Patients should be aware of this risk and be informed about potential symptoms.”

Those symptoms can include fatigue, dizziness, weight loss and salt cravings, the authors write in the Journal of Clinical Endocrinology and Metabolism.

Corticosteroids are man-made drugs designed to mimic the hormone cortisol, which the adrenal glands produce naturally. The drugs are usually used to counter inflammation in a wide range of conditions, including asthma, psoriasis, rheumatoid arthritis, lupus, blood cancers and organ transplants.

People with adrenal insufficiency do not make enough of two hormones, cortisol and aldosterone. Cortisol helps the body respond to stress, recover from infections and regulate blood pressure and metabolism. Aldosterone helps maintain the right amounts of salt, potassium and water in the body.

While on steroids, the body often produces less of these hormones naturally, and after coming off the drugs it can take a while for natural production to ramp back up. The result is adrenal insufficiency, which can be treated with medication to replace cortisol or aldosterone.

Dekkers and colleagues analyzed 74 research articles published from 1975 to 2014, covering a total of 3753 study participants, to see how different doses and types of corticosteroid treatment might impact the likelihood of developing adrenal insufficiency after treatment.

Researchers found the risk of adrenal insufficiency was highest when corticosteroids were taken orally or injected, and lower with inhaled, nasal or topical treatment.

When they looked just at patients using steroids for asthma, the researchers found that the risk of adrenal insufficiency was about 7 percent with inhaled corticosteroids, but about 44 percent with other formulations including oral medication.

Only about 2 percent of asthma patients on the lowest dose of steroids experienced adrenal insufficiency, compared with about 22 percent on the highest doses.

Similarly, slightly more than 1 percent of asthma patients on short-term steroids developed adrenal insufficiency, compared with about 27 percent on long-term treatment.

There is no way to safely halt treatment with corticosteroids that can rule out the potential for adrenal insufficiency, Dekkers said.

The side effect is more likely when patients take higher doses of steroids or remain on treatment for longer than three weeks, said Dr. Roberto Salvatori, medical director of the pituitary center at Johns Hopkins Hospital in Baltimore.

“It’s likely, and it’s often overlooked because most often the people who prescribe corticosteroids aren’t endocrinologists; they are in other specialities and they don’t recognize the symptoms of adrenal insufficiency,” said Salvatori, who wasn’t involved in the study.

He gives his patients on corticosteroids medical identification bracelets or necklaces to wear so they can be identified as at risk for adrenal insufficiency in an emergency. “This is a very important issue that’s not on the radar screen,” he said.

To be sure, more physicians are aware of the risk now than in the 1970s, and the standard doses and durations of corticosteroid treatment have been reduced in part because of this risk, said Dr. Douglas Coursin, a professor at the University of Wisconsin School of Medicine and Public Health in Madison. He, too, advises medical alert bracelets for patients on long-term or high-dose treatment.

“In the past, patients with asthma, certain immune diseases, those receiving some cancer therapies and those who had a solid organ transplant received higher doses for longer periods of time,” Coursin, who wasn’t involved in the study, said by email. “Overall, I think the risk may be lower than outlined in the study because of practice changes.”

Abstract

Context:

Successful tumor resection in endogenous Cushing’s syndrome (CS) results in tertiary adrenal insufficiency requiring hydrocortisone replacement therapy.

Objective:

The aim was to analyze the postsurgical duration of adrenal insufficiency of patients with Cushing’s disease (CD), adrenal CS, and ectopic CS.

Design:

We performed a retrospective analysis based on the case records of 230 patients with CS in our tertiary referral center treated from 1983–2014. The mean follow-up time was 8 years.

Patients:

We included 91 patients of the three subtypes of CS undergoing curative intended surgery and documented followup after excluding cases with persistent disease, pituitary radiation, concurrent adrenostatic or somatostatin analog treatment, and malignant adrenal disease.

Results:

The probability of recovering adrenal function within a 5 years followup differed significantly between subtypes (P = .001). It was 82% in ectopic CS, 58% in CD and 38% in adrenal CS. In the total cohort with restored adrenal function (n = 52) the median time to recovery differed between subtypes: 0.6 years (interquartile range [IQR], 0.03–1.1 y) in ectopic CS, 1.4 years (IQR, 0.9–3.4 y) in CD, and 2.5 years (IQR, 1.6–5.4 y) in adrenal CS (P = .002). In CD the Cox proportional-hazards model showed that the probability of recovery was associated with younger age (hazard ratio, 0.896; 95% confidence interval, 0.822–0.976; P = .012), independently of sex, body mass index, duration of symptoms, and basal ACTH and cortisol levels. There was no correlation with length and extend of hypercortisolism or postoperative glucocorticoid replacement doses.

Conclusions:

Time to recovery of adrenal function is dependent on the underlying etiology of CS.
