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). Subjects confirmed undergo imaging, followed by adrenal venous sampling (AVS) for lateralization...

Adrenal venous sampling (AVS) is the gold standard test for distinguishing between unilateral and bilateral primary aldosteronism (PA); however, AVS requires advanced and time consuming technique. The needs for AVS have been increasing due to the increased utilization of screening for PA. An efficient selection of unilateral PA, such as aldosterone-producing adenoma (APA), before AVS is useful to avoid undesirable AVS in bilateral PA, such as idiopathic hyperaldosteronism. In this study, 40 patients who received all three confirmatory tests, including the captopril challenge test, furosemide upright test and adrenocorticotropin (ACTH) stimulation test (AST), and who were diagnosed as having PA by AVS were recruited...

INTRODUCTION: The aldosterone/ renin ratio is the initial screening test for primary hyperaldosteronism (PHA), but little data exists regarding ethnic variations in this. METHODS: Following clinical observation of a high prevalence of abnormal ARR in patients of African origin, we retrospectively reviewed all ARR measurements in a single centre over 10 years. Rates of hypokalaemia, intraventricular septal thickness (IVS, by echocardiography) and adrenal imaging were recorded when available...

Less than 15% of hypertension cases in children are secondary to a primary hyperaldosteronism. This is idiopathic in 60% of the cases, secondary to a unilateral adenoma in 30% and 10% remaining by primary adrenal hyperplasia, familial hyperaldosteronism, ectopic aldosterone production or adrenocortical carcinoma.To date, four types of familial hyperaldosteronism (FH I to FH IV) have been reported. FH III is caused by germline mutations in KCNJ5, encoding the potassium channel Kir3.4. The mutations cause the channel to lose its selectivity for potassium, allowing large quantities of sodium to enter the cell...

: 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. Hence, the finding of an adrenal mass at imaging does not reliably detect the culprit of primary aldosteronism...

Context: The involvement of visceral fat in aldosterone secretion has not been reported in patients with primary aldosteronism (PA). Patients with PA are complicated by metabolic syndrome more frequently than those without PA. An excess of visceral fat has been hypothesized to cause an elevation of aldosterone secretion in patients with PA. Objectives: To clarify the role of visceral fat in the pathophysiology of PA, we investigated the correlation between plasma aldosterone concentration (PAC) and visceral fat parameters in patients with PA...

Primary aldosteronism affects ≈5% to 10% of hypertensive patients and has unilateral and bilateral forms. Most unilateral primary aldosteronism is caused by computed tomography-detectable aldosterone-producing adenomas, which express CYP11B2 (aldosterone synthase) and frequently harbor somatic mutations in aldosterone-regulating genes. The cause of the most common bilateral form of primary aldosteronism, idiopathic hyperaldosteronism (IHA), is believed to be diffuse hyperplasia of aldosterone-producing cells within the adrenal cortex...

Context: Primary aldosteronism (PA) represents the most frequent form of endocrine hypertension. Hyperaldosteronism and hypercortisolism both induce excessive left ventricular hypertrophy (LVH) compared with matched essential hypertensives. In recent studies frequent cosecretion of cortisol and aldosterone has been reported in patients with PA. Objective: Our aim was to investigate the impact of cortisol cosecretion on LVH in patients with PA. We determined 24-hour excretion of mineralocorticoids and glucocorticoids by gas chromatography-mass spectrometry and assessed cardiac remodeling using echocardiography initially and 1 year after initiation of treatment of PA...

Primary hyperaldosteronism (PHA) is the most common form of secondary hypertension of hormonal origin. It affects about 10% of all hypertensive patients. It is connected with increased morbidity and mortality from cardiovascular diseases (CVD) compared to patients with essential hypertension of a similar age. Usually, it is an effect of bilateral adrenal hyperplasia (BAH) or aldosterone-producing adenoma (APA), more rare causes of PHA are: unilateral adrenal hyperplasia, aldosterone-producing adrenocortical carcinoma, ectopic aldosterone-producing tumors and familial hyperaldosteronism...

Primary aldosteronism is the most common form of endocrine hypertension with a prevalence of 6% in the general population with hypertension. The genetic basis of the four familial forms of primary aldosteronism (familial hyperaldosteronism FH types I-IV) and the majority of sporadic unilateral aldosterone-producing adenomas has now been resolved. Familial forms of hyperaldosteronism are, however, rare. The sporadic forms of the disease prevail and these are usually caused by either a unilateral aldosterone-producing adenoma or bilateral adrenal hyperplasia...

The first discovery of primary hyperaldosteronism secondary to an aldosterone-secreting adrenal adenoma has been credited solely to Dr. Jerome Conn, an endocrinologist at the University of Michigan and for whom, Conn syndrome was named. Dr. William Baum, a urologist at the University of Michigan, however, was instrumental in the appropriate operation and historical aldosteronoma resection. Despite Dr. Baum's important role in this discovery, he was never included as an author in any of the subsequent papers describing Conn syndrome and, few today would recognize his name...

Aldosterone is the main mineralocorticoid hormone in humans and plays a key role in maintaining water and electrolyte homeostasis. Primary aldosteronism (PA), characterized by autonomous aldosterone overproduction by the adrenal glands, affects 6% of the general hypertensive population and can be either sporadic or familial. Aldosterone-producing adenoma (APA) and bilateral adrenal hyperplasia (BAH) are the two most frequent subtypes of sporadic PA and 4 forms of familial hyperaldosteronism (FH-I to FH-IV) have been identified...

Acute hypokalemic paralysis is a relatively rare cause of acute weakness. It may resolve spontaneously; however, it may be a potential life-threatening condition. Hypertension may be considered the most important finding in combination with hypokalemic paralysis for raising the suspicion of primary hyperaldosteronism (PHA). A 55-year-old hypertensive Mexican woman was admitted to the Emergency Unit with a sudden onset of generalized paralysis. An endocrinological workup and an abdominal magnetic resonance imaging revealed PHA with a 1...

Background: Primary hyperaldosteronism is a known cause for secondary hypertension. In addition to its effect on blood pressure, aldosterone exhibits proinflammatory actions and plays a role in immunomodulation/development of autoimmunity. Recent researches also suggest significant thyroid dysfunction among patients with hyperaldosteronism, but exact causal relationship is not established. Autoimmune hyperthyroidism (Graves' disease) and primary hyperaldosteronism rarely coexist but underlying mechanisms associating the two are still unclear...

Primary aldosteronism is the most common type of secondary hypertension affecting 6-10% of patients with primary hypertension. PA is mainly caused by unilateral hyperaldosteronism due to an aldosterone-producing adenoma, unilateral hyperplasia with or without micronodules or bilateral zona glomerulosa hyperplasias with or without macro or micronodules. The development of antibodies against the terminal enzyme of aldosterone biosynthesis (CYP11B2) has permitted the further characterization of normal adrenals and resected adrenals from patients with primary aldosteronism...

The 2017 Endocrine Society annual meeting included several communications and debates on the conservative adrenal surgery in bilateral hereditary pheochromocytomas (BHP), bilateral adrenal macronodular hyperplasia (BAMH) and primary hyperaldosteronism (PHA). The general principle is to preserve a part of the adrenal cortex to prevent the occurrence of a definitive adrenal insufficiency. In BHP, cortical sparing surgery allows more than 50% of patients to maintain normal corticotropic function at 10 years with a low recurrence rate (~ 10%)...
