Basics: Meds: Recorlev Tuesday Oct 28
Cushing’s disease is a progressive pituitary disorder in which there is an excess of cortisol in the body. While the disease can be treated surgically, this option is not possible for all patients. This is one of the approved medications that assist in controlling cortisol levels in people with Cushing’s disease. Recorlev was approved by the FDA in December 2021 to treat those Cushing’s patients for whom surgery is not a choice or has failed to lower cortisol levels.

Basics: Testing: Dex Tests Wednesday Oct 29
Dexamethasone suppression test measures whether adrenocorticotrophic hormone (ACTH) secretion by the pituitary can be suppressed. How the Test is Performed Cushing's: A comprehensive guide to understanding a devastating condition Wednesday Oct 29
By Dr. Lewis Blevins: This book is perhaps something a little different than most would expect. Firstly, it's a single-author book on Cushing's syndrome. It is not, like most textbooks, a compendium of edited submissions from multiple authors where there are often divergent opinions from one chapter to the next. Instead, it's a treatise reflecting my education and experience. It is not referenced but instead each chapter is followed by suggested readings. It represents my thoughts, understanding and a personal reflection on a career of evaluating a multitude of patients suspected of having the disorder and treating those confirmed to have hypercortisolism due to one cause or another. It reflects my perspectives of the art and science of the field. More info at https://cushings.invisionzone.com/topic/57752-cushings-a-comprehensive-guide-to-understanding-a-devastating-condition/
Home cortisol tests: 3 of the best Thursday Oct 30
There are several home cortisol tests available to purchase over the counter or online. These allow a person to take a sample of blood, urine, or saliva before sending it off for analysis. After taking a home cortisol test, people can usually receive their results within 2–5 days online or via a telephone call with a healthcare professional. However, there are currently no studies investigating the reliability of these home cortisol tests. Therefore, people should follow up on their test results with a healthcare professional.

Some pain is normal after any surgery. Different people have different levels of sensitivity to pain. In general, you should experience a little less pain every day. Pain is usually worse in the evening when you are trying to go to sleep. Do not be afraid to take the pain medicine prescribed for you, particularly before you go to sleep, but you can stop taking it if you are comfortable. Most pain medications cause constipation and they can also cause drowsiness. Do not drive or operate power tools after you take narcotic pain medications. If you have only mild discomfort, try taking extra-strength Tylenol® as directed. https://cushings-help.com/2024/10/30/adrenalectomy-and-bla/ Cushing’s Syndrome Masquerading as Fibromyalgia: A Case Series Thursday Oct 30
Three young female patients with a history of generalized body pain were diagnosed with fibromyalgia. They visited several specialities which related patients' symptoms to their previous diagnosis of fibromyalgia and were treated symptomatically. These patients developed a multitude of clinical features including fractures, hypertension, abnormal weight gain, proximal myopathic pain and bruising. They were seen by rheumatologists whose assessment was that their clinical features were not entirely due to fibromyalgia and suspected that patients have a possible underlying endocrine cause. Patients were referred to an endocrinologist for further tests with suspicion of Cushing’s syndrome. Laboratory tests and imaging confirmed a diagnosis of Cushing’s syndrome. Two of them had adrenal adenoma and one had iatrogenic corticosteroid use. These cases emphasize the need for thorough clinical evaluation for patients who are thought to have fibromyalgia. Fibromyalgia is a diagnosis of exclusion. Read more at https://cushings.invisionzone.com/topic/57756-cushing%E2%80%99s-syndrome-masquerading-as-fibromyalgia-a-case-series/
Ectopic ACTH-secreting Pheochromocytoma Without Typical Signs of Cushing Syndrome Saturday Nov 1
Abstract This case report describes a 42-year-old female with a rare pheochromocytoma presenting without classic Cushingoid features but with uncontrolled hypertension, type 2 diabetes, and recurrent headaches. Despite the absence of typical signs, biochemical analysis revealed elevated cortisol and ACTH levels, and imaging showed a 6 cm adrenal mass. The patient was stabilized preoperatively with alpha-blockers and metyrapone before undergoing a successful laparoscopic adrenalectomy. Histopathology confirmed pheochromocytoma with aggressive features. Postoperatively, her blood pressure and symptoms improved, and her cortisol levels normalized. This case underscores the diagnostic challenges of ACTH-secreting pheochromocytomas without classic hypercortisolism signs and emphasizes the need for thorough endocrine and imaging assessments. Surgical resection remains the definitive treatment, with long-term follow-up essential to monitor for recurrence. This case contributes to the limited literature on the coexistence of pheochromocytoma and ectopic ACTH secretion. https://cushings.invisionzone.com/topic/57818-ectopic-acth-secreting-pheochromocytoma-without-typical-signs-of-cushing-syndrome/ Global Longitudinal Strain Reduction With Apical Sparing in Cushing Syndrome-Related Heart Failure With Preserved Ejection Fraction (HFpEF) Saturday Nov 1
We describe a case of a 56-year-old woman with a history of recurrent pituitary adenoma, not well followed, and known comorbidities of coronary artery disease, hypertension, and type 2 diabetes mellitus. She arrived with severely high blood pressure and signs pointing to hypercortisolism. Further evaluation revealed left ventricular hypertrophy, reduced global longitudinal strain, and preserved left ventricular ejection fraction, consistent with heart failure with preserved ejection fraction (HFpEF). Workup for amyloidosis was negative. This case highlights that chronic hypercortisolism may cause pathophysiological changes in the heart, leading to HFpEF, and may induce myocardial fibrosis and impaired myocardial mechanics, producing an echocardiographic pattern that can mimic infiltrative cardiomyopathy. Recognition of this overlap is crucial to avoid misdiagnosis and to ensure timely endocrine and cardiovascular management. https://cushings.invisionzone.com/topic/57888-global-longitudinal-strain-reduction-with-apical-sparing-in-cushing-syndrome-related-heart-failure-with-preserved-ejection-fraction-hfpef/ Cushing's Basics: What is Cortisol? Saturday Nov 1
Cortisol is a hormone which produced by the adrenal gland (cortex) to control blood sugar. The production of cortisol is triggered by the pituitary hormone ACTH. Cortisol is a glucocorticoid which stimulates an increase in blood glucose. Cortisol will also stimulate the release of amino acids from muscle tissue and fatty acids from adipose tissue. The amino acids are then converted in the liver to glucose (for use by the brain). The fatty acids can be used by skeletal muscles for energy (rather than glucose) thereby freeing up glucose for selective utilization by the brain. Cortisol levels are often measured to evaluate the function of the pituitary or adrenal glands. Some of the cortisol is metabolized by the liver to produce 17 hydroxycorticosteroids, which is then excreted in the urine.
