Characteristics of Benign Adrenocortical Adenomas with 18F-FDG PET Accumulation.

Eur J Endocrinol 2021 May 1. Epub 2021 May 1.

K Yokote, Department of Endocrinology, Hematology and Gerontology, Chiba University, Chiba, Japan.

Introduction: Although 18F-FDG PET was originally developed to evaluate benign and malignant tumors, the frequency of detection of benign adrenocortical adenomas showing FDG-PET accumulation has increased. However, the details of FDG-PET-accumulated benign adrenocortical adenomas have not been elucidated.

Methods: To elucidate the pathophysiology of FDG-PET-positive cortisol-producing adrenal tumors, we performed clinicopathological and genetic analyses of adrenocortical adenomas examing FDG-PET in 30 operated patients with unilateral cortisol-producing adrenal tumors (26 adrenal adenomas and 4 adrenal cancers).

A Rare Independent Left Inferior Phrenic Vein Sampling in a Left Adrenal Aldosterone-Producing Adenoma.

Radiol Case Rep 2021 Jun 10;16(6):1443-1446. Epub 2021 Apr 10.

Department of Radiology, Nerima Hikarigaoka hospital, Tokyo, 179-0072, Japan.

This report presents a case of left adrenal aldosterone-producing adenoma (APA) diagnosed by segmental adrenal venous sampling in a patient with primary aldosteronism and a rare venous anomaly in which the left inferior phrenic vein (LIPV) and adrenal central vein entered the left renal vein separately. The outflow of tumor blood into the LIPV and the specimen from the LIPV that showed much higher aldosterone level than that from the adrenal central vein and tributaries were useful for proving the aldosterone hypersecretion from the APA. Sampling from the LIPV could be of diagnostic value for left APA. Read More

Recent Development toward the Next Clinical Practice of Primary Aldosteronism: A Literature Review.

Biomedicines 2021 Mar 17;9(3). Epub 2021 Mar 17.

Division of Nephrology, Endocrinology and Vascular Medicine, Tohoku University Graduate School of Medicine, Sendai 980-8575, Japan.

For the last seven decades, primary aldosteronism (PA) has been gradually recognized as a leading cause of secondary hypertension harboring increased risks of cardiovascular incidents compared to essential hypertension. Clinically, PA consists of two major subtypes, surgically curable and uncurable phenotypes, determined as unilateral or bilateral PA by adrenal venous sampling. In order to further optimize the treatment, surgery or medications, diagnostic procedures from screening to subtype differentiation is indispensable, while in the general clinical practice, the work-up rate is extremely low even in the patients with refractory hypertension because of the time-consuming and labor-intensive nature of the procedures.

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.

Molecular Genetic and Genomic Alterations in Cushing's Syndrome and Primary Aldosteronism.

Front Endocrinol (Lausanne) 2021 12;12:632543. Epub 2021 Mar 12.

Section on Endocrinology and Genetics, Eunice Kennedy Shriver National Institute of Child Health & Human Development (NICHD), National Institutes of Health (NIH), Bethesda, MD, United States.

The genetic alterations that cause the development of glucocorticoid and/or mineralocorticoid producing benign adrenocortical tumors and hyperplasias have largely been elucidated over the past two decades through advances in genomics. In benign aldosterone-producing adrenocortical tumors and hyperplasias, alteration of intracellular calcium signaling has been found to be significant in aldosterone hypersecretion, with causative defects including those in , and In benign cortisol-producing adrenocortical tumors and hyperplasias abnormal cyclic adenosine monophosphate-protein kinase A signaling has been found to play a central role in tumorigenesis, with pathogenic variants in , and being implicated. The role of this signaling pathway in the development of Cushing's syndrome and adrenocortical tumors was initially discovered through the study of the underlying genetic defects causing the rare multiple endocrine neoplasia syndromes McCune-Albright syndrome and Carney complex with subsequent identification of defects in genes affecting the cyclic adenosine monophosphate-protein kinase A pathway in sporadic tumors.

EBioMedicine 2021 Apr 25;66:103294. Epub 2021 Mar 25.

Departments of Medicine, David Geffen School of Medicine, University of California, Los Angeles, United States; Departments of Neurosurgery, David Geffen School of Medicine, University of California, Los Angeles, United States. Electronic address:

Background: Cushing disease (CD), although rare, is a life-threatening disorder caused by an adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma, which leads to excess adrenal-derived cortisol. Efficacious and safe medical therapies that control both hormonal hypersecretion and pituitary corticotroph tumor growth remain an unmet need in the management of CD. Translational research in pituitary tumors has been significantly hampered by limited quantities of surgically resected tissue for ex vivo studies, and unavailability of human pituitary tumor cell models.
