Second-Line Tests in the Diagnosis of Adrenocorticotropic Hormone-Dependent Hypercortisolism.

Ann Lab Med 2021 Nov;41(6):521-531

Endocrinology Unit, Department of Medicine (DIMED), University-Hospital of Padova, Padova, Italy.

Cushing's syndrome (CS) is a rare disease caused by chronic and excessive cortisol secretion. When adrenocorticotropin hormone (ACTH) is measurable, autonomous adrenal cortisol secretion could be reasonably ruled out in a differential diagnosis of CS. ACTH-dependent CS accounts for 80%-85% of cases and involves cortisol production stimulated by uncontrolled pituitary or ectopic ACTH secretion. Read More

Cortisol Co-Secretion and Clinical Usefulness of ACTH Stimulation Test in Primary Aldosteronism: A Systematic Review and Biases in Epidemiological Studies.

Front Endocrinol (Lausanne) 2021 16;12:645488. Epub 2021 Mar 16.

Endocrinology and Diabetes Center, Yokohama Rosai Hospital, Yokohama, Japan.

The hypothalamus-pituitary-adrenal (HPA) axis plays an important role in primary aldosteronism. Aldosterone biosynthesis is regulated not only by angiotensin II in the renin-angiotensin-aldosterone system, but also by adrenocorticotropic hormone (ACTH), one of the key components of the HPA axis. Although previous studies have reported cortisol cosecretion in primary aldosteronism, particularly aldosterone-producing adenoma (APA), the clinical relevance of such aldosterone and cortisol cosecretion from APA and hypertension or other metabolic disorders has not been fully established.

Feasibility of Iodine-131 6β-Methyl-Iodo-19 Norcholesterol (NP-59) Scintigraphy to Complement Adrenal Venous Sampling in Management of Primary Aldosteronism: A Case Series.

Int J Gen Med 2021 1;14:673-680. Epub 2021 Mar 1.

Division of Endocrinology and Metabolism, Department of Internal Medicine, Eunpyeong St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea.

Purpose: Primary aldosteronism (PA) is mainly comprised of aldosterone-producing adenoma and bilateral idiopathic adrenal hyperplasia. Current guidelines recommend adrenal venous sampling (AVS) as a gold standard method to classify the subtypes. However, because of technical challenges in AVS including invasiveness of AVS and a wide range of success rate for cannulation, it is not uncommon that appropriate decisions could not be made depending on AVS.

Multiple enlarging hepatic and retroperitoneal myelolipomas in the setting of Cushing disease.

BMJ Case Rep 2021 Feb 23;14(2). Epub 2021 Feb 23.

Department of Radiology, University of Utah Health, Salt Lake City, UT, USA.

Myelolipomas are benign tumours typically occurring in the adrenal glands, made up of fat and trilineage haematopoeitic cells resembling bone marrow. Their aetiology is not well understood; however, they have a clear association with elevated serum adrenocorticotropic hormone (ACTH). Extra-adrenal myelolipomas are rare, and to our knowledge there are no previously reported cases of multiple enlarging hepatic and retroperitoneal myelolipomas in the setting of Cushing disease.

SILENT CORTICOTROPH TUMOR WITH ADRENOCORTICAL CHORISTOMA IN AN ELEVEN-YEAR-OLD BOY.

J Clin Res Pediatr Endocrinol 2021 Feb 15. Epub 2021 Feb 15.

Istanbul University-Cerrahpaşa, Cerrahpaşa Faculty of Medicine, Department of Pediatric Endocrinology, Istanbul, Turkey.

Silent corticotroph tumors are composed of corticotroph cells, but do not manifest any biochemical or clinical evidence of hypercortisolism. A choristoma is a benign, congenital proliferation of histologically mature tissue elements normally not present at the site of occurrence. The existence of adrenocortical cells within the pituitary gland, which can be explained as a choristoma, is a very rare entity, and the co-occurrence of these two entities have only been reported in few cases.
