Primary aldosteronism: comparison between guidelines of the Japanese and the US Endocrine Society.

Expert Rev Endocrinol Metab 2012 Nov;7(6):637-645

a Endocrinology and Diabetes Center, Yokohama Rosai Hospital, Yokohama, Kanagawa 222-0036, Japan.

The US and Japanese Endocrine Societies recently both developed a therapeutic guideline for primary aldosteronism (PA). These guidelines indicate that differential diagnosis between PA caused by aldosterone-producing adenoma (APA) and bilateral adrenal hyperplasia (or idiopathic hyperaldosteronism [IHA]) is important and critical for treatment choice, while they show some inconsistency due to different frequencies of disorders and medical circumstances in respective countries. Japanese Endocrine Society guidelines have a unique description on the adrenal vein sampling (AVS) against microAPA, detection of which is difficult with current imaging tools and thus is frequently misdiagnosed as IHA.

Diagnostic value of adrenal iodine-131 6-beta-iodomethyl-19-norcholesterol scintigraphy for primary aldosteronism: a retrospective study at a medical center in North Taiwan.

Nucl Med Commun 2019 Jan 28. Epub 2019 Jan 28.

Department of Internal Medicine, Division of Endocrinology and Metabolism, College of Medicine.

Background: Primary aldosteronism (PA) is a common cause of secondary hypertension. Among the many leading causes of PA, the two most frequent are, bilateral adrenal hyperplasia (BAH) and aldosterone-producing adenomas (APA). Since a solitary APA may be cured surgically, but BAH needs lifelong pharmacologic therapy, confirmation is mandatory before surgery. Read More

Imaging features of adrenal masses.

Insights Imaging 2019 Jan 25;10(1). Epub 2019 Jan 25.

Dipartimento di Biomedicina, Neuroscienze e Diagnostica Avanzata, Università degli studi di Palermo, Via del Vespro 127, 90127, Palermo, Italy.

The widespread use of imaging examinations has increased the detection of incidental adrenal lesions, which are mostly benign and non-functioning adenomas. The differentiation of a benign from a malignant adrenal mass can be crucial especially in oncology patients since it would greatly affect treatment and prognosis. In this setting, imaging plays a key role in the detection and characterization of adrenal lesions, with several imaging tools which can be employed by radiologists. Read More

Primary Aldosteronism: Present and Future.

Authors:
John W Funder

Vitam Horm 2019 23;109:285-302. Epub 2018 Dec 23.

Hudson Institute of Medical Research, Clayton, VIC, Australia; Monash University, Clayton, VIC, Australia. Electronic address:

Primary aldosteronism (PA), currently recognized to be 5-10% of hypertension, has a cardiovascular risk profile double that in age-, sex-, and blood pressure-matched essential hypertensives. Screening for PA is by determining the plasma aldosterone to renin ratio (ARR), followed by one of half a dozen confirmatory/exclusion tests. Unilateral hyperaldosteronism normally reflects an aldosterone producing adenoma; bilateral disease is the more common form, and termed idiopathic hyperaldosteronism (IHA). Read More

Aldosterone and 18-Oxocortisol Coaccumulation in Aldosterone-Producing Lesions.

Hypertension 2018 Dec;72(6):1345-1354

From the Department of Biochemistry (Y.S., M.S., K.N.), Keio University School of Medicine, Tokyo, Japan.

Primary aldosteronism is a secondary hypertensive disease caused by autonomous aldosterone production that often caused by an aldosterone-producing adenoma (APA). Immunohistochemistry of aldosterone synthase (CYP11B2) shows the presence of aldosterone-producing cell clusters (APCCs) even in non-primary aldosteronism adult adrenal cortex. An APCC-like structure also exists as possible APCC-to-APA transitional lesions (a speculative designation) in primary aldosteronism adrenals. Read More

10 good reasons why adrenal vein sampling is the preferred method for referring primary aldosteronism patients for adrenalectomy.

J Hypertens 2019 Mar;37(3):603-611

Division of Clinical Hypertension, Endocrinology and Metabolism, Tohoku University Graduate School of Medicine, Sendai, Japan.

: Nowadays most patients diagnosed with surgically curable primary aldosteronism have small or micro aldosterone-producing adenoma or unilateral micronodular hyperplasia, which are undetectable with available imaging technologies. Therefore, a negative imaging test by no means excludes unilateral primary aldosteronism. Moreover, about 10% of the subjects above the age of 35 years have nonfunctioning adrenal tumors, regardless of being hypertensive or not, with a prevalence that raises with aging. Read More

A variable course of Cushing's disease in a 7 year old: diagnostic dilemma.

J Pediatr Endocrinol Metab 2018 Nov;31(11):1285-1288

Fellow Pediatric Endocrinology, Indraprastha Apollo Hospital, New Delhi, India.

Background Cushing's syndrome (CS) or hypercortisolism results from disruption of the hypothalamus-pituitary-adrenal (HPA) axis with the resultant increase in the circulating serum and urinary cortisol levels and lack of cortisol circadian rhythm. The resultant effects cause the physical manifestation of hypercortisolism. The appearance of Cushing's disease in children is insidious, the most common features being growth failure, obesity, early puberty and facial appearance. Read More

Autonomous hypercortisolism: definition and clinical implications.

Minerva Endocrinol 2019 Mar 2;44(1):33-42. Epub 2018 Jul 2.

Unit of Internal Medicine and Endocrinology, Department of Clinical and Biological Sciences, San Luigi Gonzaga University Hospital, University of Turin, Orbassano, Turin, Italy.

In current practice, an adrenal adenoma usually comes as an unexpected byproduct of an imaging study performed for unrelated reasons, without any prior suspect of adrenal disease. Therefore, these tumors currently represent a public health challenge because they are increasingly recognized due to the widespread use of high-resolution cross-sectional imaging for diagnostic purposes. In radiology series, the prevalence of adrenal adenomas increases steeply with age, from around 3% below the age of 50 years up to 10% in the ageing population. Read More

Saline suppression test parameters may predict bilateral subtypes of primary aldosteronism.

Clin Endocrinol (Oxf) 2018 Sep 26;89(3):308-313. Epub 2018 Jun 26.

Department of Endocrinology, Monash Health, Clayton, Vic., Australia.

Background: The saline suppression test (SST) serves to confirm the diagnosis of primary aldosteronism (PA) whilst adrenal vein sampling (AVS) is used to determine whether the aldosterone hypersecretion is unilateral or bilateral. An accurate prediction of bilateral PA based on SST results could reduce the need for AVS.

Aim: We sought to identify SST parameters that reliably predict bilateral PA. Read More
