Brzana J, et al. – This study aims to retrospectively review institutional records of female patients of reproductive age with Cushing’s disease (CD) and determine if and how many had been previously diagnosed as having solely PCOS. To determine whether clinical patterns might be useful in identifying appropriate candidates for hypercortisolism screening in women suspected of PCOS. Prolonged exposure to hypercortisolism has been linked with increased mortality and morbidity. Tests for hypercortisolism in all the PCOS cases authors report led to an appropriate CD diagnosis. Future research should focus on when and which (if not all) women with suspected PCOS should be tested for hypercortisolism.

Methods

  • The study included 50 patients with pathologically proven CD at Oregon Health & Science University, Northwest Pituitary Center between 2006 and 2011.
  • Physical, clinical, and biochemical features for hypercortisolism were compared.

Results

  • Of 50 patients with pathologically proven CD, 26 were women of reproductive age.
  • Of these, half had previously been diagnosed with and treated initially solely for PCOS.
  • Hirsutism and menstrual abnormalities were more common in the group with an initial PCOS diagnosis than in the group with an initial CD diagnosis.

Abstract

Background: The outcome of bilateral adrenalectomy (BADx) in patients with Cushing’s syndrome (CS) is not well characterized.

Methods: A literature search was performed with the search terms “bilateral adrenalectomy” or “total adrenalectomy” and “Cushing’s” or “Cushing.” Immediate and long-term outcomes after BADx in CS were analyzed using descriptive statistics (median [range]).

Results: From 549 screened publications, 37 studies met inclusion criteria (1320 patients, 82% having Cushing’s disease [CD], 13% having ectopic CS, and 5% having primary adrenal hyperplasia).

Surgical morbidity and mortality of BADx (23 studies, 739 patients) were 18% (6–31) and 3% (0–15), respectively. In patients with CD, surgical mortality was below 1%. Although residual cortisol secretion due to accessory adrenal tissue or adrenal remnants was found in 3–34% (5 studies, 236 patients), less than 2% had a relapse of CS.

Symptoms of hypercortisolism (eg, hypertension, obesity, or depression) improved in the majority of the patients after BADx (7 studies, 195 patients). The number of adrenal crises per 100 patient-years was 9.3 (6 studies, 203 patients).

Nelson’s syndrome occurred in 21% (0–47) of the patients (24 studies, 768 patients). Mortality (23 studies, 690 patients) was 17% (0–88) at a follow-up of 41 months (14–294). Remarkably, 46% of the patients died in the first year after surgery. The median ages at death were 62 years (CD) and 53 years (ectopic CS).

Conclusion: BADx is relatively safe and provides adequate success. Excess mortality within the first year after surgery suggests that intensive clinical care for patients after BADx is warranted.

Yaneva MK et al. – Data on the incidence, mortality and causes of death in patients with Cushing’s syndrome (CS) are scarce, due to the rarity of CS. The aim of the study was to analyze mortality rates in CS in a large cohort of patients of all etiologies and to determine the cause of death. Patients with CS have increased mortality due to vascular events and infections.

Abstract

OBJECTIVE:

Data on the incidence, mortality and causes of death in patients with Cushing’s syndrome (CS) are scarce, due to the rarity of CS. The aim of the study was to analyze mortality rates in CS in a large cohort of patients of all etiologies and to determine the cause of death.

DESIGN:

This was a retrospective study of patients with CS, treated over a period of 45 years in the main tertiary referral center in Bulgaria.

METHODS:

386 patients with CS of all etiologies were included. The main outcome measures were the standardized mortality ratio (SMR) and the cause of death.

RESULTS:

Mean (± SD) age at diagnosis was 38±13 years; 84% of patients were women; mean follow up was 85 months (range: 0-494 months). The SMR in the CS cohort was 4.05 (95% confidence interval (CI) 2.50-5.80) (p<0.0001). The following subgroups did not have a significantly increased SMR: patients with Cushing’s disease SMR – 1.88 (95%CI 0.69-4.08), adrenal adenomas 1.67 (95%CI 0.20-6.02) and ACTH-independent bilateral adrenal hyperplasia 1.14 (95 %CI 0.21-6.34). Patients with adrenal carcinomas, ectopic CS and those with CS of undetermined etiology had significantly increased SMR: 48.00 (95%CI 30.75-71.42), 13.33 (95%CI 0.00-24.59) and 4.00 (95%CI 0.48-14.45), respectively (p<0.0001). The significant predictors for mortality were active disease at death, age, male sex, etiology of the disease, the overall duration of active disease. The major causes of death were vascular events (40%) -cardiovascular 29% and cerebrovascular 11%, followed by infections (12%).

CONCLUSIONS:

Patients with CS have increased mortality due to vascular events and infections.

Cushing’s Syndrome is Hazardous to Your Health

Posted on July 3, 2013 by MaryO

morbidity

People with Cushing’s syndrome, even when treated, have higher morbidity and mortality rates that comparable controls. That is the conclusion of a new study published in the June issue of the Journal of Clinical Endocrinology Metabolism. The study by Olaf Dekkers et al, examined data records from the Danish National Registry of Patients and the Danish Civil Registration System of 343 patients with benign Cushing’s syndrome of adrenal or pituitary origin (i.e., Cushing’s disease) and a matched population comparison cohort (n=34,300).  Due to the lengthy delay of many patients being diagnosed with Cushing’s syndrome, morbidity was investigated in the 3 years before diagnosis while  morbidity and mortality were assessed during complete follow-up after diagnosis and treatment.

The study found that mortality was twice as high in Cushing’s syndrome patients (HR 2.3, 95% CI 1.8-2.9) compared with controls over a mean follow-up period of 12.1 years. Furthermore, patients with Cushing’s syndrome were at increased risk for:

  • venous thromboembolism (HR 2.6, 95% CI 1.5-4.7)
  • myocardial infarction (HR 3.7, 95% CI 2.4-5.5)
  • stroke (HR 2.0, 95% CI 1.3-3.2)
  • peptic ulcers (HR 2.0, 95% CI 1.1-3.6)
  • fractures (HR 1.4, 95% CI 1.0-1.9)
  • infections (HR 4.9, 95% CI 3.7-6.4).

The study also found that this increased multimorbidity risk was present before diagnosis indicating that it was due to cortisol overproduction rather than treatment.

Many of the Cushing’s syndrome patients underwent surgery to remove the benign tumor. For this group, the investigators performed a sensitivity analysis of the  long-term mortality and cardiovascular risk in this  subgroup (n=186)  considered to be cured after operation (adrenal surgery and patients with pituitary surgery in combination with a diagnosis of hypopituitarism in the first 6 months after operation).  The risk estimates for mortality (HR 2.31, 95% CI 1.62-3.28), venous thromboembolism (HR 2.03, 95% CI 0.75-5.48), stroke (HR 1.91, 95% CI 0.90-4.05), and acute myocardial infarction (HR 4.38, 95% CI 2.31-8.28) were also increased in this subgroup one year after the operation.

The standard treatment for endogenous Cushing’s syndrome is surgery. This past year, Signifor (pasireotide) was approved for treatment of adults patients with Cushing’s disease for whom pituitary surgery is not an option or has not been curative.  Cushing’s disease, which accounts for the majority of Cushing’s syndrome patients, is defined as the presence of an ACTH producing tumor on the pituitary grand. In the study by Dekker’s et al, the percentage of patients with Cushing’s disease is not known. We look forward to reexamination of this dataset in a few years following the introduction of more treatment options for Cushing’s disease as well as an analysis that explores the differences in mortality/morbidity rates in the different subsets of patients that make of Cushing’s syndrome (Cushing’s disease, ectopic Cushing’s syndrome, Exogenous Cyshing’s syndrome).

Predictors of Mortality, CVD Risk in Cushing’s Disease ID’d

Posted on February 28, 2013 by MaryO

(HealthDay News) – A number of factors, including the duration of glucocorticoid exposure, older age at diagnosis, and preoperative adrenocorticotropic hormone (ACTH) concentration, are associated with a higher risk of mortality in patients treated for Cushing’s disease (CD), according to research published online Feb. 7 in the Journal of Clinical Endocrinology & Metabolism.

In an effort to identify predictors of mortality, cardiovascular disease, and recurrence with long-term follow-up, Jessica K. Lambert, MD, of the Mount Sinai Medical Center in New York City, and colleagues performed a retrospective chart review of 346 patients with CD who underwent transsphenoidal adenectomy.

The researchers found that the average length of exposure to glucocorticoids was 40 months. The risk of death was higher for those patients who had a longer duration of glucocorticoid exposure, older age at diagnosis, and higher preoperative ACTH concentration. For patients who achieved remission, depressed patients had a higher risk of death. The risk of cardiovascular disease was highest for men, older people, and those with diabetes or depression.

“Our study has identified several predictors of mortality in patients with treated CD, including duration of exposure to excess glucocorticoids, preoperative ACTH concentration, and older age at diagnosis. Depression and male gender predicted mortality among patients who achieved remission,” the authors write. “These data illustrate the importance of early recognition and treatment of CD. Long-term follow-up, with management of persistent comorbidities by an experienced endocrinologist, is needed even after successful treatment of CD.”
