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...

PURPOSE OF REVIEW: Primary aldosteronism is the most common form of secondary hypertension. Early diagnosis and treatment are key to cure of hypertension and prevention of cardiovascular complications. Recent genetic discoveries have improved our understanding on the pathophysiology of aldosterone production and triggered the development of new diagnostic procedures and targeted treatments for primary aldosteronism. RECENT FINDINGS: Different inherited genetic abnormalities distinguish specific forms of familial hyperaldosteronism...

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...

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...

Gregory Kline, Daniel T Holmes
Primary aldosteronism (PA) is the most common form of secondary hypertension and is critical to identify because when caused by an aldosterone-producing adenoma (APA) or another unilateral form, it is potentially curable, and even when caused by bilateral disease, antihypertensives more specific to PA treatment can be employed (ie, aldosterone antagonists). Identification of unilateral forms is not generally accomplished with imaging because APAs may be small and elude detection, and coincidental identification of a non-functioning incidentaloma contralateral to an APA may lead to removal of an incorrect gland...

Primary aldosteronism (PA) is the most common form of secondary hypertension (HTN), with an estimated prevalence of 4% of hypertensive patients in primary care and around 10% of referred patients. Patients with PA have higher cardiovascular morbidity and mortality than age- and sex-matched patients with essential HTN and the same degree of blood pressure elevation. PA is characterized by an autonomous aldosterone production causing sodium retention, plasma renin supression, HTN, cardiovascular damage, and increased potassium excretion, leading to variable degrees of hypokalemia...

BACKGROUND: Despite being widely recognized as the most common form of secondary hypertension, among the general hypertensive population the true prevalence of primary aldosteronism (PA) and its main subtypes, aldosterone-producing adenoma (APA) and bilateral adrenal hyperplasia (BAH), remains a matter of debate. OBJECTIVES: This study sought to determine the prevalence and clinical phenotype of PA in a large cohort of unselected patients with hypertension, consecutively referred to our hypertension unit, by 19 general practitioners from Torino, Italy...

Primary aldosteronism (PA) is an important and commonly unrecognized cause of secondary hypertension. Idiopathic hyperaldosteronism and aldosterone-producing adenomas account for more than 95% of PA and are characterized, respectively, by bilateral or unilateral involvement of the adrenal glands. When there is suspicion for the presence of PA, a plasma aldosterone to renin ratio should be obtained initially. Localization to determine adrenal gland involvement is done by imaging, with computerized tomography or magnetic resonance imaging...

Primary aldosteronism (PA) is a heterogeneous group of disorders including both sporadic and familial forms (familial hyperaldosteronism type I, II and III). PA is the most frequent endocrine cause of secondary hypertension and associated with a higher rate of cardiovascular complications, compared with essential hypertension.Here I review the recent progress in understanding of the genetic and molecular mechanisms leading to autonomous aldosterone production in PA.Systematic screening detects primary aldosteronism in 5 to 10% of all patients with hypertension and in approximately 20% of patients with resistant hypertension...

Hypertension is a common medical condition and affects approximately 20% of the population in developed countries. Primary aldosteronism is the most common form of secondary hypertension and affects 8-13% of patients with hypertension. The two most common causes of primary aldosteronism are aldosterone-producing adenoma and bilateral adrenal hyperplasia. Familial hyperaldosteronism types I, II and III are the known genetic syndromes, in which both adrenal glands produce excessive amounts of aldosterone. However, only a minority of patients with primary aldosteronism have one of these syndromes...

BACKGROUND: The distinction between unilateral aldosterone-producing adenoma or bilateral adrenal hyperplasia as causes of primary aldosteronism is usually made by adrenal CT or by adrenal vein sampling (AVS). Whether CT or AVS represents the best test for diagnosis remains unknown. We aimed to compare the outcome of CT-based management with AVS-based management for patients with primary aldosteronism. METHODS: In a randomised controlled trial, we randomly assigned patients with aldosteronism to undergo either adrenal CT or AVS to determine the presence of aldosterone-producing adenoma (with subsequent treatment consisting of adrenalectomy) or bilateral adrenal hyperplasia (subsequent treatment with mineralocorticoid receptor antagonists)...

Primary aldosteronism (PA) is the most frequent endocrine cause of secondary arterial hypertension. Sporadic forms of PA caused mainly by an aldosterone producing adenoma (APA) or idiopathic adrenal hyperplasia (IAH) predominate; in contrast, familial forms (familial hyperaldosteronism types I, II and III) affect only a minor proportion of PA patients. Patient based registries and biobanks, international networks and next generation sequencing technologies have emerged over recent years. Somatic hot-spot mutations in the potassium channel GIRK4 (encoded by KCNJ5), in ATPases and a L-type voltage-gated calcium-channel correlate with the autonomous aldosterone production in approximately half of all APAs...

Primary aldosteronism is the most common cause of secondary hypertension with an estimated prevalence of 5-13 % among patients with hypertension. The most common causes are aldosterone producing adrenal adenoma and idiopathic adrenal hyperplasia. Patients with primary aldosteronism have a higher prevalence of cardiovascular morbidity and mortality compared to patients with essential hypertension. An effective treatment is available for patients with primary aldosteronism, with mineralocorticoid receptor antagonists in bilateral, and minimal invasive adrenal surgery in unilateral disease, which emphasizes the importance of early detection, adequate diagnostic work-up and treatment...

Primary aldosteronism is the most common cause of secondary hypertension. Less than 50 cases of pregnancy in women with primary aldosteronism have been reported, suggesting the disorder is significantly underdiagnosed in confinement. Accurate diagnosis is complicated by physiological changes in the renin-angiotensin-aldosterone axis in pregnancy, leading to a risk of false negative results on screening tests. The course of primary aldosteronism during pregnancy is highly variable, although overall it is associated with a very high risk of fetal and maternal morbidity and mortality...

BACKGROUND: Recent studies have found that mild secondary hyperparathyroidism might be another clinical feature of patients with primary aldosteronims (PA), but whether serum parathyroid hormone level (PTH) is correlated with subtypes of PA and what contributes to the elevated PTH level remains unclear. OBJECTIVE: To illustrate the changes of PTH in PA and to partly explain the mechanism of how the effects of aldosterone regulating the secretion of PTH in PA. METHODS: We enrolled a total of 120 patients with primary hypertension (PH) and 242 patients with PA, which included 89 APAs (aldosterone-producing adenoma), 119 IHAs (idiopathic hyperaldosteronism) and 34 UAHs (unilateral adrenal hyperplasia)...

UNLABELLED: Myxoedema madness was first described as a consequence of severe hypothyroidism in 1949. Most cases were secondary to long-standing untreated primary hypothyroidism. We present the first reported case of iatrogenic myxoedema madness following radioactive iodine ablation for Graves' disease, with a second concurrent diagnosis of primary hyperaldosteronism. A 29-year-old woman presented with severe hypothyroidism, a 1-week history of psychotic behaviour and paranoid delusions 3 months after treatment with radioactive iodine ablation for Graves' disease...
