Endogenous Cushing’s Syndrome arises from the body’s own overproduction of cortisol due to adrenal tumors, pituitary adenomas, or other factors. Key differences lie in patient history and hormone levels.
Diagnostic tests can reveal distinct patterns; for example, iatrogenic cases usually show suppression of adrenal function on hormone evaluation. In contrast, endogenous cases often exhibit elevated ACTH levels depending on the source of excess cortisol production.
Pathophysiology of Glucocorticoid-Induced Cushing’s Syndrome
Glucocorticoid-induced Cushing’s syndrome occurs when there is an excess of glucocorticoids in the body, primarily from prolonged steroid use. These hormones regulate metabolism, immune response, and stress reactions. When administered externally, they disrupt the body’s natural feedback mechanisms.

The hypothalamus-pituitary-adrenal (HPA) axis becomes suppressed due to high levels of circulating glucocorticoids. This suppression leads to decreased production of adrenocorticotropic hormone (ACTH), which normally stimulates cortisol release from the adrenal glands.
As a result, patients may face various complications such as hypertension, obesity, and insulin resistance. The chronic exposure alters normal physiological functions and contributes significantly to morbidity associated with iatrogenic Cushing’s syndrome.
Clinical Features and Symptoms
Iatrogenic Cushing’s Syndrome manifests through a range of clinical features and symptoms that can significantly affect quality of life. Common signs include weight gain, particularly around the abdomen, face, and neck. Patients may also develop a characteristic round face often referred to as “moon facies.”
Skin changes are frequent as well; thinning skin leads to easy bruising and slow healing. Striae or purple stretch marks may appear on the abdomen and thighs.

Iatrogenic Cushing’s Syndrome can significantly impact cardiovascular health. Prolonged exposure to glucocorticoids leads to increased blood pressure and altered lipid profiles. These changes heighten the risk of hypertension, a common complication in affected individuals.
Furthermore, excess cortisol promotes insulin resistance, further aggravating cardiovascular risks. Elevated levels of triglycerides and LDL cholesterol contribute to the development of atherosclerosis. This condition narrows arteries and raises the chance of heart attacks.
Patients with iatrogenic Cushing’s often face an elevated risk for various heart-related issues. Regular monitoring is essential to manage these risks effectively and prevent serious complications down the line.
Psychiatric and Cognitive Manifestations
Iatrogenic Cushing’s Syndrome can lead to significant psychiatric and cognitive issues. Patients may experience mood swings, anxiety, and depression. These symptoms arise from the effects of excess glucocorticoids on brain chemistry.
Cognitive impairment is another concern. Individuals often report difficulties with memory, attention, and executive functions. This decline in mental clarity can impact daily activities and quality of life.
The psychological burden can be overwhelming for many patients. Social withdrawal and changes in self-esteem are common as individuals struggle to cope with their condition. Addressing these manifestations is crucial for holistic management of Iatrogenic Cushing’s Syndrome.
Diagnostic Approaches and Hormonal Evaluation
Diagnosing iatrogenic Cushing’s syndrome involves a careful evaluation of clinical symptoms alongside hormonal assessments. Physicians start with a detailed medical history, focusing on any long-term steroid use. Symptoms such as weight gain, easy bruising, and skin changes often prompt further testing.
Hormonal evaluations typically include measuring cortisol levels in urine and saliva. A 24-hour urinary free cortisol test is commonly employed to assess elevated cortisol production. Additionally, late-night salivary cortisol measurements can indicate abnormal diurnal variation.
Blood tests may also be conducted to evaluate adrenocorticotropic hormone (ACTH) levels. These results help determine if the excess cortisol originates from exogenous sources or if other underlying issues exist.
Imaging Studies in Iatrogenic Cushing’s Syndrome
Imaging studies play a crucial role in diagnosing iatrogenic Cushing’s Syndrome. These tests help differentiate between the causes of excess cortisol, paving the way for appropriate management strategies.
Magnetic resonance imaging (MRI) is typically employed to evaluate pituitary gland abnormalities. It can reveal adenomas that might be causing excessive hormone production.
Computed tomography (CT) scans are also valuable, particularly when assessing adrenal glands and detecting any structural changes or tumors. Both imaging modalities provide essential information that aids healthcare professionals in formulating an effective treatment plan tailored to each patient’s needs.
Management Strategies: Tapering Glucocorticoids
Tapering glucocorticoids is a critical management strategy for individuals with iatrogenic Cushing’s syndrome. Gradually reducing the dosage helps mitigate withdrawal symptoms and restores adrenal function. A slow taper allows the body to adjust, minimizing stress on the hypothalamic-pituitary-adrenal (HPA) axis.
Healthcare providers typically create a personalized tapering schedule based on factors like duration of steroid use and individual patient response. Monitoring during this process is essential, as some patients may require adjustments in their tapering plan due to fluctuating symptoms.
Close collaboration between patients and healthcare teams ensures effective communication throughout this phase. It’s vital for patients to report any side effects or concerns promptly, allowing timely interventions if necessary.
