BACKGROUND: Even with recent treatment advances, type 2 diabetes (T2D) remains poorly controlled for many patients, despite the best efforts to adhere to therapies and lifestyle modifications. Although estimates vary, studies indicate that in >10% of individuals with difficult-to-control T2D, hypercortisolism may be an underlying contributing cause. To better understand the prevalence of hypercortisolism and the impact of its treatment on T2D and associated comorbidities, we describe the two-part Hyper c ortisolism in P at ients with Difficult to Control Type 2 Di a betes Despite Receiving Standard-of-Care Therapies: Preva l ence and Treatment with Korl y m® (Mifepri st one) (CATALYST) trial.
METHODS: In part 1, approximately 1000 participants with difficult-to-control T2D (haemoglobin A1c (HbA1c) 7.5%-11.5% despite multiple therapies) are screened with a 1 mg dexamethasone suppression test (DST). Those with post-DST cortisol >1.8 µg/dL and dexamethasone level ≥140 ng/dL are identified to have hypercortisolism (part 1 primary endpoint), have morning adrenocorticotropic hormone (ACTH) and dehydroepiandrosterone sulfate (DHEAS) measured and undergo a non-contrast adrenal CT scan. Those requiring evaluation for elevated ACTH are referred for care outside the study; those with ACTH and DHEAS in the range may advance to part 2, a randomised, double-blind, placebo-controlled trial to evaluate the impact of treating hypercortisolism with the competitive glucocorticoid receptor antagonist mifepristone (Korlym®). Participants are randomised 2:1 to mifepristone or placebo for 24 weeks, stratified by the presence/absence of an abnormal adrenal CT scan. Mifepristone is dosed at 300 mg once daily for 4 weeks, then 600 mg daily based on tolerability and clinical improvement, with an option to increase to 900 mg. The primary endpoint of part 2 assesses changes in HbA1c in participants with hypercortisolism with or without abnormal adrenal CT scan. Secondary endpoints include changes in antidiabetes medications, cortisol-related comorbidities and quality of life.
BACKGROUND: The study has been approved by Cleveland Clinic IRB (Cleveland, Ohio, USA) and Advarra IRB (Columbia, Maryland, USA). Findings will be presented at scientific meetings and published in peer-reviewed journals.

Pheochromocytoma is a chromaffin cell-derived adrenal medullary tumour and usually presents with paroxysms of hypertension, palpitations, sweating and headache due to excessive catecholamine release. These tumours can also secrete a variety of bioactive neuropeptides and hormones other than catecholamines, resulting in unusual clinical manifestations. We report a female in her mid-30s who presented with fever, anaemia, thrombocytosis and markedly elevated inflammatory markers. The fever profile, including cultures, was negative. Contrast-enhanced CT of abdomen showed a large solid-cystic right adrenal lesion with elevated plasma-free normetanephrine levels suggestive of pheochromocytoma. The fever persisted despite empirical antibiotics and antipyretics. Interleukin-6 (IL-6) levels were elevated (41.2 pg/mL (3-4 pg/mL)). She was initiated on naproxen (NPX) at a dose of 250 mg two times per day. The patient responded to NPX, and after stabilisation, she underwent an adrenalectomy. There was a complete resolution of fever with normalisation of IL-6 levels postoperatively.

With only 15 reported cases, anastomosing haemangioma of adrenal is a rare entity and usually presents as adrenal incidentaloma. A hypertensive, diabetic, non-smoker man in his late 60s presented with irritative voiding symptoms. On evaluation, he was found to have a urinary bladder mass and left adrenal incidentaloma measuring 8 cm. Metabolic evaluation confirmed it to be non-functional.The patient underwent transurethral resection of bladder tumour with left laparoscopic adrenalectomy. Intraoperatively, the adrenal tumour was highly vascular with multiple feeder vessels. Grossly it was soft, encapsulated with focal grey-brown areas. Microscopically, most of adrenal gland was replaced by anastomosing proliferating capillary vessels within framework of non-endothelial supporting cells reminiscent of splenic sinusoids. The tumour was positive for CD-31, CD-34, Glut-1 and SMA.Anastomosing haemangioma is a benign entity but it must be differentiated from angiosarcoma. Characteristic imaging features are not yet defined and is, therefore, difficult to diagnose preoperatively.

OBJECTIVE: While glucocorticoid (GC) treatment initiated for COVID-19 reduces mortality, it is unclear whether GC treatment prior to COVID-19 affects mortality. Long-term GC use raises infection and thromboembolic risks. We investigated if patients with oral GC use prior to COVID-19 had increased mortality overall and by selected causes.
METHODS: Population-based observational cohort study.
METHODS: Population-based register data in Sweden.
METHODS: All patients infected with COVID-19 in Sweden from January 2020 to November 2021 (n=1 200 153).
METHODS: Any prior oral GC use was defined as ≥1 GC prescription during 12 months before index. High exposure was defined as ≥2 GC prescriptions with a cumulative prednisolone dose ≥750 mg or equivalent during 6 months before index. GC users were compared with COVID-19 patients who had not received GCs within 12 months before index. We used Cox proportional hazard models and 1:2 propensity score matching to estimate HRs and 95% CIs, controlling for the same confounders in all analyses.
RESULTS: 3378 deaths occurred in subjects with any prior GC exposure (n=48 806; 6.9%) and 14 850 among non-exposed (n=1 151 347; 1.3%). Both high (HR 1.98, 95% CI 1.87 to 2.09) and any exposure (1.58, 1.52 to 1.65) to GCs were associated with overall death. Deaths from pulmonary embolism, sepsis and COVID-19 were associated with high GC exposure and, similarly but weaker, with any exposure. High exposure to GCs was associated with increased deaths caused by stroke and myocardial infarction.
CONCLUSIONS: Patients on oral GC treatment prior to COVID-19 have increased mortality, particularly from pulmonary embolism, sepsis and COVID-19.

In this case report, we describe an uncommon presentation of Cushing\'s syndrome in a patient in their 60s who presented to the emergency department with left-sided chest pain. The initial workup for the patient was unremarkable except for an elevated blood pressure and elevated fasting plasma glucose. A CT scan of the chest, abdomen and pelvis was performed, demonstrating a splenic artery thrombus with multiple splenic infarcts, in addition to a combination of macronodular adrenal hyperplasia, bilateral gynecomastia, centripetal fat distribution and suspected mild bone demineralisation. Adrenocorticotropic hormone-independent macronodular adrenal hyperplasia, a rare aetiology responsible for Cushing\'s syndrome, was raised as a potential unifying diagnosis for the patient\'s hypercoagulable status, which was subsequently confirmed on an endocrinological investigation. The case report underscores the importance of communicating clinically relevant details to the imaging specialist in combination with considering a broad differential, including endocrine disorders, when evaluating an undifferentiated patient with atypical imaging findings.

The incidence of adrenal cysts is 0.06% and only 9% of these are true mesothelial cysts. Here, we present a case of a true mesothelial cyst together with a review of the literature. A female in her 30s presented to the surgical outpatient department complaining of right flank pain. Her contrast-enhanced CT scan revealed a 7.5×6.5×4.5 cm right adrenal gland cyst. The patient underwent a laparoscopic right adrenalectomy. Immunohistopathology revealed the cyst to be mesothelial in nature. The majority of true mesothelial adrenal cysts are benign, unilateral and more common in women. Any adrenal cyst diagnosed as a functional lesion or one that may be malignant or with a diameter of 5 cm or greater requires surgical care whereas smaller lesions can be managed conservatively. Laparoscopic adrenalectomy for an adrenal cyst of diameter greater than 6 cm is a safe and feasible procedure in expert hands if there is no invasion of surrounding tissue.

Hypoglycaemia is one of the most common causes of convulsions in neonatal period. Repeated hypoglycaemic convulsions have to be addressed with utmost urgency to prevent its morbid sequelae. Repeated ketotic hypoglycaemia in the infantile period needs detailed endocrine evaluation. Our patient is a boy in the third year of his life, had presented in infancy with hypoglycaemic convulsions and hyperpigmentation of skin and mucous membrane. Investigations revealed ketotic hypoglycaemia, hypocortisolaemia with high adrenocorticotropic hormone (ACTH) and normal aldosterone, 17-hydroxyprogesterone (17-OHP) and testosterone levels. This suggested isolated glucocorticoid deficiency without mineralocorticoid deficiency. He responded well to hydrocortisone therapy with resolution of symptoms and normalisation of lab parameters. Genetic study confirmed the diagnosis of familial glucocorticoid deficiency (FGD) with homozygous mutation in NNT (nicotinamide nucleotide transhydrogenase) gene with a novel p.Thr578lle variant. This is the first case of FGD with NNT mutation to be reported from the Indian subcontinent.

A woman in her late 50s with recent onset of hypertension, diabetes, lumbar pain and unintentional weight loss was diagnosed with a cortisol and androgen-producing adrenal mass. Despite this, serum adrenocorticotropic hormone (ACTH) concentration was inappropriately elevated, which was investigated thoroughly. Investigations included a brain magnetic resonance imaging to exclude concomitant pituitary adenoma, a corticotropin-releasing hormone stimulation test and a gallium-68 DOTATATE and 18F-FDOPA PET scan, both excluding ectopic ACTH production. Considering the disparity between clinical presentation and biochemical results, the ACTH was reanalysed using the Cobas immunoassay (Roche, Switzerland), ultimately unveiling the cause for ACTH elevation. ACTH levels had previously been measured with ACTH Immulite (Siemens, Germany), a two-site immunoassay which is prone to interferences causing falsely elevated ACTH concentrations. Inaccurate laboratory levels can lead to diagnosis delay and unnecessary diagnostic procedures and a close communication between the physicians and laboratorians is of utmost importance.

We report the case of a middle-aged hypertensive woman presenting to the neurology department with short-lasting episodic headaches for 4 years. She was initially diagnosed and treated with cluster headaches for one year. Following this, she presented with right lower limb arterial claudication. Arterial Doppler of lower limbs showed thrombosis of the bilateral common femoral arteries. Further computed tomography (CT) angiogram of the lower limbs confirmed extensive arterial thrombosis in bilateral lower limbs. The CT angiogram incidentally detected a left adrenal lesion. She had elevated urinary vanillylmandelic Acid and 24-hour metanephrines suggesting the presence of a pheochromocytoma. She was initially medically managed and later underwent left open adrenalectomy. Histopathology examination of the sections proved pheochromocytoma. Postsurgery, the patient\'s symptoms improved remarkably. This case highlights the importance of diagnosing pheochromocytoma when you encounter a patient with refractory short-lasting headaches, hypertension and hypercoagulability.

An adult male in his early 30s diagnosed with multiple endocrine neoplasia type 2A syndrome, confirmed through genetic testing, presented as bilateral pheochromocytoma in a metachronous fashion, primary hyperparathyroidism and medullary thyroid carcinoma. Left and right adrenalectomy was done 9 years and 3 years ago, respectively. He was also subjected to total thyroidectomy with neck dissection and left inferior parathyroidectomy. During surveillance monitoring, 24-hour total urine metanephrines were elevated 13.977 mg (Normal value 0-1 mg) 1 year after right adrenalectomy. Adrenal CT scan demonstrated a 2.1 cm ovoid focus in the right suprarenal region, and functional imaging (131I meta-iodobenzylguanidine (MIBG scan) showed an avid uptake on the right frontal bone. Excision of the right adrenal bed and the right frontal bone tumour was performed, and metastatic pheochromocytoma was confirmed histologically. The patient achieved clinical and biochemical remission postoperatively and is currently receiving steroid and thyroxine replacement.
