Multisystem Morbidity and Mortality in Cushings Syndrome: a Cohort Study

Journal of Clinical Endocrinology and Metabolism, 03/28/2013  Clinical Article

Dekkers O.M. et al.– To examine the risks for mortality, cardiovascular disease, fractures, peptic ulcers, and infections in CS patients before and after treatment.Cushing’s syndrome (CS) is associated with hypercoagulability, insulin resistance, hypertension, bone loss, and immunosuppression. To date, no adequately large cohort study has been performed to assess the multisystem effects of CS. It was concluded that despite the apparently benign character of the disease, CS is associated with clearly increased mortality and multisystem morbidity, even before diagnosis and treatment.
  • The study used Cox–regression, and computed hazard ratios (HR) with 95% confidence intervals (95% CI).
  • Morbidity was investigated in the three years before diagnosis; morbidity and mortality was assessed during complete follow–up after diagnosis and treatment.
  • 343 CS patients and 34,300 controls were included. Mortality was twice as high in CS patients (HR 2.3, 95%CI 1.8–2.9) compared with controls.
  • Patients with CS 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), and infections (HR 4.9, 95%CI 3.7–6.4).
  • This increased multi–morbidity risk was present before diagnosis. Mortality and risk of myocardial infarction remained elevated during long–term follow–up.
  • Mortality and risks for AMI, VTE, stroke and infections were similarly increased in adrenal and pituitary CS.

Early diagnosis of pediatric Cushing’s disease improved surgical outcomes

Lonser RR. J Clin Endocrinol Metab. 2013;93:892-901.

  • March 27, 2013
Early postoperative endocrine testing could predict lasting remission among pediatric patients with Cushing’s disease, according to recent study findings published in the Journal of Clinical Endocrinology & Metabolism. Other findings suggest early diagnosis has the potential to improve surgical outcomes due to an association with younger age, smaller adenomas and lack of dural invasion.
Researchers at the NIH included 200 pediatric patients (106 females, 94 males) with Cushing’s disease in the prospective observational study from 1982 to 2010. The mean age was 10.6 years (range; 4 to 19 years) at the time of symptom development and 13.7 years at the time of the NIH study. However, 27 (13%) patients underwent prior surgery at another institution, the researchers reported.
Using MRI, researchers identified adenomas in 97 patients (50%); when positive, the MRI accurately specified discrete adenoma in 96 of the 97 patients (99%). The researchers wrote that this was more accurate compared with adrenocorticotropic hormone (ACTH) ratios during inferior petrosal sinus sampling to influence adenoma lateralization (accurate in 72% of patients without prior surgery).
Moreover, 195 of the 200 patients (98%) demonstrated remission after surgery (189 [97%] were hypocortisolemic; six [3%] were eucortisolemic postoperatively). Factors associated with initial remission (P<.05) included identification of an adenoma at surgery, immunohistochemical ACTH-producing adenoma and noninvasive ACTH adenoma.
According to researchers, younger age, smaller adenoma and absence of cavernous sinus wall or other dural invasion were associated with long-term remission (P<.05). Finally, minimum morning serum cortisol of less than 1 mcg/dL after surgery also demonstrated a positive predictive value for a lasting remission of 96%, the researchers wrote.

Depressed Mood and Other Psychiatric Manifestations of Cushing's Syndrome: Relationship to Hormone Levels

Thirty-five consecutive patients with Cushing's syndrome were studied prospectively prior to treatment.

A consistent constellation of psychiatric disturbances was found, including impairments in affect (depressed mood and crying), cognitive functions (decreased concentration and memory), and vegetative functions (decreased libido and insomnia).

A statistically significant relationship was found between the overall psychiatric disability rating and cortisol and ACTH level. The relationship of depressed mood and hormone levels was examined. Low ACTH levels were significantly associated with milder rather than pronounced depressed mood.

The implications of the similarities in psychiatric manifestations between Cushing's syndrome and the primary affective disorders are discussed.

Exophthalmos is typically associated with Graves' ophthalmopathy. Although originally described by Harvey Cushing, exophthalmos is an underappreciated sign of Cushing's syndrome. We present a case of a 38-year-old female who presented with severe bilateral proptosis and was subsequently diagnosed with Cushings disease. We discuss the possible mechanisms causing exophthalmos in patients with either endogenous or exogenous hypercortisolemia.

1. Case Presentation

A 38-year-old female noticed progressively worsening bilateral proptosis for a period of two years, to the point causing episodes of ocular dislocation from her sockets. She also noted irregular menstrual cycles during this time and was amenorrheic for 6 months prior to referral. She underwent extensive workup by her primary care physician including thyroid tests which were normal. She then underwent orbital decompression surgery in June 2011 with transient improvement of symptoms. However in the next 12 months she gained 60 lbs and developed proximal muscle weakness, purplish abdominal striae, facial hirsutism, and easy bruisability. She was also diagnosed with new onset diabetes and hypertension during this time and was treated with Metformin and Lisinopril, respectively. Physical examination revealed an obese female with a BMI of 43 and BP . She had frank stigmata of Cushings syndrome (CS). She had bilateral proptosis with Hertel’s exophthalmometry readings of 26 mm (right) and 27 mm (left) (Figure 1). Visual acuity was  bilaterally. There was no corneal/conjunctival congestion or lid retraction/lag. Fundus exam was normal. Extraocular movements were intact and visual fields were normal on confrontation. Tonometry was not performed. Labs done prior to referral indicated midnight salivary cortisol of 654 ng/dL (normal 112 ng/dL) and post 1 mg dexamethasone cortisol of 16.9 mcg/dL. Random ACTH level was 50 (8–42 pg/mL). MRI of pituitary gland revealed 1.6 cm macroadenoma with deviation of the stalk to the right (Figure 2). MRI also indicated bilateral exophthalmos with increased retrorbital fat (Figure 2). Prolactin was 40 (2–17.4 ng/mL) consistent with stalk effect, gonadotropins were low, and IGF-1, free T4 were normal. Patient underwent trans-sphenoidal removal of the tumor which stained diffusely with ACTH (Figure 3). Patient is being treated with hydrocortisone and followed closely by her ophthalmologist. Although the exophthalmos persisted after the pituitary surgery, episodes of ocular dislocation had not occurred at 3 months followup.

2. Discussion

Exophthalmos or proptosis refers to forward displacement of the eyeball. It has to be differentiated from retraction of the eyelids, which can cause an illusion of exophthalmos. Conventionally, exophthalmos refers to ocular proptosis secondary to endocrinopathies. Graves’ disease is the most common endocrine cause of exophthalmos. Although described in 1932 by Harvey Cushing in 4 of his 12 patients with Cushings disease, this is an often forgotten clinical sign [1] in patients with CS. We have presented a case highlighting the importance of exophthalmos and its association with hypercortisolemia.
Exophthalmos is seen in about 30–45% of patients with Cushings syndrome (CS) [13]. Kelly reported that exophthalmos (exceeding 16 mm) occurred in 45% of active CS, 21% of iatrogenic CS, and 20% of treated CS in comparison to 2% in controls [3]. Cases of severe exophthalmos preceding the evolution of CS have been reported in the literature [45].
The cause of exophthalmos in CS is still unknown. Multiple theories have been proposed including fat redistribution and increased retro-orbital fat, associated thyroid disease, and an exophthalmos causative factor. It has been proposed that retro-orbital fat deposition is also part of the fat re-distribution seen in CS, resulting in increase in volume of the retro-orbital tissues and a consequent rise in intra-orbital pressure [36]. Orbital fat volume was increased in patients with CS and orbital muscles are relatively spared [78]. In contrast to patients with Graves’ disease the retrorbital fat in CS is devoid of inflammatory cell infiltration. Whether differential fat deposition in the orbits is due to increased glucocorticoid receptor density, defective lipolysis or increased lipoprotein lipase activity is not known.

Cushing’s Syndrome, Prostate Cancer and Adrenocortical Carcinoma

Orphagen has identified and characterized small molecule antagonists to steroidogenic factor-1 (SF-1). SF-1 binds to and regulates DNA promoter elements in the major transporters and enzymes required for adrenal steroid synthesis. It is also required for development of the adrenal gland. SF-1 antagonists inhibit cortisol secretion in adrenal cells and have potential application in two orphan indications, Cushing’s syndrome and adrenocortical carcinoma. In addition, SF-1 appears to have an important role in the progression of advanced prostate cancer.


  Cushing’s syndrome: An estimated 20,000 people in the US have Cushing’s, with more than 3,000 new cases diagnosed each year. The incidence is similar in Europe. Cushing’s syndrome disproportionately affects females, who make up about 75% of the diagnosed cases. Symptoms of Cushing’s syndrome can include obesity, diabetes, psychiatric disorders, osteoporosis and immune suppression. Cushing’s syndrome is caused by elevated secretion of cortisol from the adrenal gland, in association with pituitary, adrenal or other cancers. Orphagen has identified small molecule antagonists to SF-1 that have the potential to suppress cortisol levels in all Cushing’s patients without serious side effects.

  Adrenocortical carcinoma (ACC): ACC is a rare malignancy with an extremely poor prognosis (5-year overall survival: 37-47%). Complete surgical resection offers hope for long-term survival but surgery is not an option in up to two-thirds of patients because metastasis has usually occurred by the time of diagnosis. SF-1 is recognized as a potential mechanism-based therapeutic target for control of ACC and an SF-1 antagonist could be used in the treatment of ACC.

  Pediatric ACC: Pediatric ACC is a very rare but aggressive cancer with a long-term survival rate of about 50%. Approximately 60% of children with adrenocortical tumors are diagnosed before the age of four. The SF-1 gene is amplified and SF-1 protein is overexpressed in the vast majority of childhood adrenocortical tumors strongly implicating SF-1 in pediatric adrenocortical tumorigenesis.

  Castration resistant prostate cancer (CRPC): CRPC is the most common cancer in males. Surgery is not an option if the cancer has spread beyond the prostate gland, at which point patients typically receive hormonal therapy, essentially chemical castration. This course of therapy usually fails within two years, resulting in castration resistant prostate cancer (CRPC). Most patients eventually succumb to CRPC, which is the second leading cause of cancer deaths in men. SF-1 antagonists may: (1) block the adrenal androgens that circumvent chemical castration, and are a primary cause of CRPC; and (2) inhibit synthesis of androgens within the prostate tumor itself, where SF-1 may control induction of enzymes for de novo androgen synthesis in treatment-resistant cancers.
