Hiding In Plain Sight: Florid Cushing’s Disease Presenting As A Severe Extremity Cellulitis

Posted on April 12, 2024 by MaryO

Abstract

Disclosure: C.M. Godar: None. E.B. Noble: None. N.O. Vietor: None. T.S. Knee: None.

Background: Cushing’s syndrome may rarely present as an emergency known as Florid Cushing’s Syndrome. Patients can exhibit severe hyperglycemia, hypertension, hypokalemia, infections, and hypercoagulability. Cushing’s syndrome is a rare disease, and the constellation of clinical features can be overlooked if clinicians are not aware of the manifestations of hypercortisolism. We present the case of a patient with Cushing’s syndrome that went unrecognized with life-threatening sequelae.

Case presentation: A 52-year-old woman with well-controlled type 2 diabetes and hypertension was admitted to the hospital for severe left lower extremity cellulitis. Prior to hospitalization she had noted rapid weight gain, fatigue, weakness, mental clouding, and moodiness. She was admitted for antibiotics and surgical debridement. The infection persisted despite broad spectrum antibiotics, multiple surgical debridements, and skin grafting. She became bacteremic, and extremity amputation was considered. She additionally developed hypertensive emergency, refractory hypokalemia, and hyperglycemia to 396 mg/dL. Exam was notable for facial plethora, supraclavicular fullness, dorsocervical fat pad, and violaceous abdominal striae. Cushing’s Syndrome was suspected, and labs revealed a significantly elevated random serum cortisol of 60.5mcg/dL (Ref 6.2-19.4), significantly elevated 24H urine cortisol of 2157mcg/24H (Ref 0-50), and ACTH elevated to 81.8pg/mL (Ref 7.2-63.3) that confirmed Cushing’s Disease. MRI sella and octreotide scans did not localize a lesion. Inpatient therapy included multiple antihypertensive agents, insulin drip, aggressive potassium repletion, and initiation of ketoconazole to reduce cortisol levels. Ketoconazole was maximally dosed and she underwent surgical exploration and removal of a small pituitary microadenoma. Following surgery, she developed transient adrenal insufficiency requiring hydrocortisone and she no longer required antihypertensives, insulin, or potassium therapy. Follow up 7 years later has revealed no recurrence of Cushing’s Disease.

Discussion: Cushing’s Syndrome may present with a variety of clinical features and rarely may present as a medical emergency. Delay in diagnosis can lead to Florid Cushing’s Syndrome which carries high risk for morbidity and mortality. This case illustrates the need for clinician awareness of the features of Cushing’s Syndrome: hypertension, hyperglycemia, rapid weight gain, cushingoid exam features, hypokalemia, hirsutism, virilization, infection, and/or hypercoagulable state. Severe hypercortisolism was responsible for this patient’s refractory infection, and if not controlled, she likely would have endured a lower extremity amputation. Rapid detection with elevated random serum and/or urine cortisol and treatment with a cortisol-lowering agent is critical and lifesaving.

Cushing’s Syndrome and Skin Problems

Posted on August 22, 2016 by MaryO

By Afsaneh Khetrapal, BSc (Hons)

Cushing’s Syndrome (sometimes called hypercortisolism) is a hormonal disease caused by an abnormally high level of the hormone cortisol in the body. This may arise because of an endogenous or exogenous source of cortisol. Endogenous causes include the elevated production of cortisol by the adrenal glands, while exogenous causes include the excessive use of cortisol or other similar steroid (glucocorticoid) hormones over a prolonged period of time.

The adrenal glands are situated just above each kidney, and form part of the endocrine system. They have numerous functions such as the production of hormones called catecholamines, which includes epinephrine and norepinephrine. Interestingly, the outer layer (cortex) of the adrenal glands has the distinct responsibility of producing cortisol. This hormone is best known for its crucial role in the bodily response to stress.

At physiologically appropriate levels, cortisol is vital in maintaining normal sleep-wake cycles, and acts to increase blood sugar levels. It suppresses the immune system, regulates the effect of insulin on the metabolism of fats, proteins, and carbohydrates, and help with the homeostasis of water in the body.

Exogenous corticosteroids can also lead to Cushing’s syndrome, when they are used as a form of long-term treatment for various medical conditions. In fact, the long-term use of steroid medication is the most common reason for the development of Cushing’s syndrome.

Prednisolone is the most commonly prescribed steroid medicine. It belongs to a class of medicine that is sometimes used to treat conditions such as certain forms of arthritis and cancer. Other uses include the rapid and effective reduction of inflammation in conditions such as asthma and multiple sclerosis (MS), as well as the treatment of autoimmune conditions such as lupus erythematosus, and rheumatoid arthritis.

Overall, Cushing’s syndrome is quite uncommon and affects approximately 1 in 50,000 people. Most of them are adults between the ages of 20 and 50.  Women are 3 times more commonly affected than men. Additionally, patients who are obese, or those who have type 2 diabetes with poorly controlled blood sugar and blood pressure show a greater predisposition to the disorder.

Symptoms of Cushing’s syndrome

There are numerous symptoms associated with Cushing’s syndrome, which range from muscle weakness, hypertension, curvature of the spine (kyphosis), osteoporosis, and depression, to fatigue Specific symptoms which pertain to the skin are as follows:

  • Thinning of the skin and other mucous membranes: the skin becomes dry and bruises easily. Cortisol causes the breakdown of some dermal proteins along with the weakening of small blood vessels. In fact, the skin may become so weak as to develop a shiny, paper-thin quality which allows it to be torn easily.
  • Increased susceptibility of skin to infections
  • Poor wound healing  of bruises, cuts, and scratches
  • Spots appear on the upper body, that is, on the face, chest or shoulders
  • Darkened skin which is seen on the neck
  • Wide, red-purple streaks (at least half an inch wide) called striae which are most common on the sides of the torso, the lower abdomen, thighs, buttocks, arms, and breasts, or in areas of weight gain. The accumulation of fat caused by Cushing’s syndrome stretches the skin which is already thin and weakened due to cortisol action, causing it to hemorrhage and stretch permanently, healing by fibrosis.
  • Acne: this can develop in patients of all ages.
  • Swollen ankles: this is caused by the accumulation of fluid, called edema.
  • Hyperhidrosis (excessive sweating)

Abstract

OBJECTIVE:

Cushing’s disease (CD) causes a wide variety of nonspecific symptoms, which may result in delayed diagnosis. It may be possible to uncover unusual combinations of otherwise common symptoms using ICD-9-CM codes. Our aim was to identify and evaluate dyads of clinical symptoms or conditions associated with CD.

METHODS:

We conducted a matched case-control study using a commercial healthcare insurance claims database, designed to compare the relative risk (RR) of individual conditions and dyad combinations of conditions among patients with CD versus matched non-CD controls.

RESULTS:

With expert endocrinologist input, we isolated 10 key conditions (localized adiposity, hirsutism, facial plethora, polycystic ovary syndrome, abnormal weight gain, hypokalemia, deep venous thrombosis, muscle weakness, female balding, osteoporosis) with RR varying from 5.1 for osteoporosis to 27.8 for hirsutism. The RR of dyads of these conditions ranged from 4.1 for psychiatric disorders/serious infections to 128.0 for hirsutism/fatigue in patients with vs. without CD. Construction of uncommon dyads resulted in further increases in RR beyond single condition analyses, such as osteoporosis alone had RR of 5.3, which increased to 8.3 with serious infections and to 52.0 with obesity.

CONCLUSION:

This study demonstrated that RR of any one of 10 key conditions selected by expert opinion was ≥5 times greater in CD compared to non-CD, and nearly all dyads had RR≥5. An uncommon dyad of osteoporosis and obesity had an RR of 52.0. If clinicians consider the diagnosis of CD when the highest-risk conditions are seen, identification of this rare disease may improve.

Abstract

Endogenous pathologic hypercortisolism, or Cushing’s syndrome, is associated with poor quality of life, morbidity and increased mortality. Early diagnosis may mitigate against this natural history of the disorder.

The clinical presentation of Cushing’s syndrome varies, in part related to the extent and duration of cortisol excess. When hypercortisolism is severe, its signs and symptoms are unmistakable. However, most of the signs and symptoms of Cushing’s syndrome are common in the general population (e.g. hypertension and weight gain) and not all are present in every patient.

In addition to classical features of glucocorticoid excess, such as proximal muscle weakness and wide purple striae, patients may present with the associated co-morbidities that are caused by hypercortisolism. These include cardiovascular disease, thromboembolic disease, psychiatric and cognitive deficits, and infections. As a result, internists and generalists must consider Cushing’s syndrome as a cause, and endocrinologists should search for and treat these co-morbidities.

Recommended tests to screen for Cushing’s syndrome include 1 mg dexamethasone suppression, urine free cortisol and late night salivary cortisol. These may be slightly elevated in patients with physiologic hypercortisolism, which should be excluded, along with exogenous glucocorticoid use. Each screening test has caveats and the choice of tests should be individualized based on each patient’s characteristics and lifestyle.

The objective of this review was to update the readership on the clinical and biochemical features of Cushing’s syndrome that are useful when evaluating patients for this diagnosis.

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
