Hyperaldosteronism, also aldosteronism, is a medical condition wherein too much aldosterone is produced by the adrenal glands, which can lead to lowered levels of potassium in the blood (hypokalemia) and increased hydrogen ion excretion (alkalosis). This cause of mineralocorticoid excess is primary hyperaldosteronism reflecting excess production of aldosterone by adrenal zona glomerulosa. Bilateral micronodular hyperplasia is more common than unilateral adrenal adenoma. Play media It can be asymptomatic, but these symptoms may be present: Fatigue Headache High blood pressure Hypokalemia Hypernatraemia Hypomagnesemia Intermittent or temporary paralysis Muscle spasms Muscle weakness Numbness Polyuria Polydipsia Tingling Metabolic alkalosis The causes of primary hyperaldosteronism are adrenal hyperplasia and adrenal adenoma (Conns syndrome). These cause hyperplasia of aldosterone-producing cells of the adrenal cortex resulting in primary hyperaldosteronism. The causes of secondary ...
Most cases of hyperaldosteronism affect younger adults between the ages of 30 and 50 years, with a female preponderance three times higher than that of males. Many studies have demonstrated evolving etiologies of hyperaldosteronism depending on how the disease is defined. Hypertensive patients who are at risk for increased aldosterone levels include very young patients with refractory hypertension and those with a strong family history of an aldosteronoma. According to the Joint National Committee, the prevalence of primary hyperaldosteronism is 1.99% in subjects with stage 1 hypertension, 8.02% in stage 2 hypertension, and 13.2% in stage 3 hypertension. In patients with resistant hypertension, the prevalence of primary aldosteronism has been reported to be 17% to 20%, but African-American and black South African subjects have lower renin levels than white subjects.3 Ethnicity, age, and gender differences have not had a profound effect on the prevalence of hyperaldosteronism. ...
Ghose and colleagues (1) showed that long-term medical management (5 to 17 years) is a reasonable option for aldosterone-producing adenomas diagnosed by standard biochemistry and computed tomography in terms of blood pressure control and normalization of serum potassium levels in patients who decline or are unfit for surgery. However, I have concerns about the diagnostic accuracy in their cohort of patients. The use of computed tomography alone without adrenal venous sampling is often inadequate in differentiating between aldosterone-producing adenomas and adrenocortical hyperplasia (2, 3), the two major causes of primary hyperaldosteronism. In a series of hypertensive patients with primary hyperaldosteronism, computed tomography alone had a low specificity (58%) and a positive predictive value of only 72% (4). With the additional use of adrenal venous sampling, a significant proportion of patients was found to have nonfunctional adrenal masses with coexisting adrenal hyperplasia (4) ...
BACKGROUND: Cosyntropin and metoclopramide can affect the subtyping of primary aldosteronism when used with adrenal vein sampling by exerting hormone- and side-specific effects on cortisol and aldosterone secretion. We investigated how these stimuli affect the selectivity index, the relative aldosterone secretion index, and the lateralization index in consecutive primary aldosteronism patients submitted to adrenal vein sampling. METHODS: We recruited 171 patients; of these, 149 underwent adrenal vein sampling before and after stimulation with cosyntropin (250 µg intravenous bolus, n= 53, 73% with an aldosterone-producing adenoma) or with metoclopramide (10 mg intravenous bolus, n= 96, 65% aldosterone-producing adenoma), and 32 with an aldosterone-producing adenoma were investigated for the relative gene expression of dopamine, melanocortin 2, and 5-hydroxytryptamine (serotonin) 4 receptor with microarrays ...
Rationale: Primary hyperaldosteronism (PA) is the most frequent and possibly curable form of secondary hypertension. The diagnosis and targeted treatment of PA is essential because of high vascular morbidity associated with PA as compared to essential hypertension with comparable blood pressure levels. PA is usually caused by either a unilateral aldosterone-producing adenoma (APA) or by bilateral adrenal hyperplasia (BAH). Distinction between APA and BAH is critical since the former may be cured by adrenalectomy, and the latter needs life-long medical therapy with mineralocorticoid receptor antagonists (MRA). Studies demonstrate that adrenalectomy benefits also BAH patients with dominant nodule(s) producing the most of aldosterone excess. The distinction between unilateral and bilateral PA can be made by adrenal vein sampling (AVS), as recommended by The Endocrine Society 2008 guideline. Currently, in Finland the diagnosis is based on computed tomography (CT) scanning which does not distinguish ...

The pathophysiological significance of the dopaminergic system in primary aldosteronism (PA) however remains unknown. In the present study, we examined the effects of metoclopramide (MCP) on Aldo. secretion in normal subjects (w=ll) and patients with essential hypertension (EH, w = 8), aldosterone-producing adenoma (APA, n = 10), and idiopathic hyper aldosteronism (IHA, n = 6).

... , also known as Conns syndrome, is considered one of the most common causes of secondary hypertension or high blood pressure. Primary aldosteronism occurs when your body produces too much aldosterone, which is a hormone that controls the sodium and patassium levels in the blood. When too much aldosterone is produced, the result is too much salt (sodium) and too little potassium in the blood, which leads to hypertension. Conns syndrome is more common in females than males and can occur at any age, but most commonly in people in their 30s and 40s. Symptoms may include muscle weakness, frequent urination, excessive thirst, or muscle twitching and cramps. Medical therapy is a good treatment option ...
Fig. 30-4 Renal pressor system.. General laboratory findings. Hypokalemia is the most typical abnormality, and the combination of hypertension and hypokalemia in a person who is not taking diuretics suggests the possibility of primary aldosteronism. However, about 20% (range, 0%-66%) of patients with primary aldosteronism have serum potassium levels within population reference range. Most of these normokalemic patients have a serum potassium value that does not exceed 4.0 mEq/L (4 mmol/L). Also, hypokalemia in a person with hypertension who is taking diuretics does not mean that hypokalemia is invariably due only to the diuretic unless the patient had already been adequately investigated for Conns syndrome. Some other diseases that may be associated with both hypertension and hypokalemia include Cushings syndrome, essential hypertension combined with diuretic therapy, potassium-losing renal disease, licorice abuse, malignant hypertension, Bartters syndrome, and the 11-b-hydroxylase variant of ...

Background |p|The Captopril challenge test (CCT) is an easy-conduct confirmatory test for diagnosing primary aldosteronism (PA). Guidelines show that plasma aldosterone is normally suppressed by captopril (> 30%) in primary hypertension (PH) and in healthy people. It is unclear whether this standard is applicable in Chinese subjects. The aim of the present study was to investigate the post-CCT efficacy of plasma aldosterone concentration (PAC) suppression and determine the post-CCT aldosterone renin activity ratio (ARR) and PAC for PA diagnosis.|/p| Methods |p|We recruited 110 consecutive patients with PA, 163 with primary hypertension (PH), and 40 healthy volunteers (NC). The CCT was conducted in all patients. Total sodium intake was estimated from 24-h urinary excretions. ROC curves were used to analyze the efficiency of different CCT diagnostic criteria for diagnosing PA.|/p| Results |p|In NC and PH patients, PRA was increased and PAC was decreased post-CCT (|i|P|/i| < 0.05).

It is well known that primary aldosteronism (PA) is the most common form of secondary hypertension, and also that aldosterone-producing adenoma and bilateral are the most common forms of PA.
Three patients with primary aldosteronism due to adrenocortical carcinoma were studied, two with hyperaldosteronism alone and one also with hypercortisolism; in the later stages all three had hypersecretion of glucocorticoid and androgenic hormones. Although clinical presentations were similar to those of patients with benign adenoma, all had significantly higher concentrations of deoxycorticosterone and aldosterone and more profound hypokalemia. Stimulation with adrenocorticotropin in two patients showed a good cortisol response but no aldosterone response. The circadian rhythm for Cortisol was normal but absent for aldosterone and deoxycorticosterone. Sequential 24-hour circadian studies in one patient showed that as the disease progressed, corticosterone and finally Cortisol lost their circadian rhythms. Treatment with spironolactone, mitotane, or aminoglutethimide had transient clinical effects. The patients died 2 to 13 years later. ...
Our results indicate that the progression of damage in three major target organs is disparate among PA and EH patients. In PA patients, LVH preceded hypertensive retinopathy and hypertensive renal involvement.. There is a paucity of information in human subjects relating the effects of prolonged hypersecretion of aldosterone on target organs. Campbell et al20 reported that in five patients with adrenal adenoma proved by autopsy, reactive and/or reparative fibrosis was found in the heart, pancreas, adrenal glands, and lung but not in the kidneys or liver. This necropsy study supports our results that the influence of aldosterone on the heart preceded the influence on the kidneys and brain in PA patients.. It is well established that aldosterone plays an important role in the pathogenesis of cardiovascular fibrosis.7 21 22 23 24 Immunohistochemical studies of intact tissue have demonstrated the presence of mineralocorticoid receptors in the cardiovascular system, supporting the possibility of ...
Aldosterone-producing adenomas (APAs) cause a sporadic form of primary aldosteronism and somatic mutations in the KCNJ5 gene, which encodes the G-protein-activated inward rectifier K+ channel 4, GIRK4, account for ≈40% of APAs. Additional somatic APA mutations were identified recently in 2 other genes, ATP1A1 and ATP2B3, encoding Na+/K+-ATPase 1 and Ca2+-ATPase 3, respectively, at a combined prevalence of 6.8%. We have screened 112 APAs for mutations in known hotspots for genetic alterations associated with primary aldosteronism. Somatic mutations in ATP1A1, ATP2B3, and KCNJ5 were present in 6.3%, 0.9%, and 39.3% of APAs, respectively, and included 2 novel mutations (Na+/K+-ATPase p.Gly99Arg and GIRK4 p.Trp126Arg). CYP11B2 gene expression was higher in APAs harboring ATP1A1 and ATP2B3 mutations compared with those without these or KCNJ5 mutations. Overexpression of Na+/K+-ATPase p.Gly99Arg and GIRK4 p.Trp126Arg in HAC15 adrenal cells resulted in upregulation of CYP11B2 gene expression and its ...

Primary Aldosteronism (PA) is a disease caused by the overproduction of aldosterone hormone from the adrenal glands. PA causes hypertension and the majority with this disease are undiagnosed for PA. There are new insights into this matter by using biochemistry as well as advanced radiology. In 2011, a breakthrough in the genetic derangements came, identifying a mutated potassium channel gene - KCNJ5 - in about 40% of PA with adenoma. Chapters in this book include a history of the disorder, epidemiology, genetics derangements, the KCNJ5 mutations and phenotype and more.. ...

Recent genetic examinations and multisteroid profiles have provided the basis for subclassification of aldosterone-producing adenomas (APAs). The objective of the current study was to produce a comprehensive, high-resolution mass spectrometry imaging (MSI) map of APAs in relation to morphometry, immunohistochemical profiles, mutational status, and clinical outcome. The study cohort comprised 136 patients with unilateral primary aldosteronism. Matrix-assisted laser desorption/ionization-Fourier transform-ion cyclotron resonance MSI was conducted, and metabolite profiles were analyzed with genotype/phenotype information, including digital image analysis from morphometry and IHC of steroidogenic enzymes. Distinct molecular signatures between KCNJ5- and CACNA1D-mutated APAs with significant differences of 137 metabolites, including metabolites of purine metabolism and steroidogenesis, were observed. Intratumor concentration of 18-oxocortisol and 18-hydroxycortisol were inversely correlated with the ...
What is the cost of AVS for the National Health System or Insurance and for patients? The second aim of the study is to calculate the rate of AVS studies that are selective and show lateralization of aldosterone excess at each center by applying predefined set of criteria for defining selectivity and lateralization. Data on the final diagnosis of the PA subtype will be gathered and used as reference to assess the performance of AVS using receiver operating characteristic curves analysis and the Youden index to determine the optimal cutoffs. A worksheet will need to be completed providing information on the following: Demography; Date of AVS;Baseline blood pressure (BP) values and serum K+;Dynamic test during the AVS if any; plasma aldosterone and cortisol concentration in the infra-adrenal inferior vena cava and in the right and left adrenal vein; diagnosis of PA subtype; treatment (adrenalectomy or pharmacological therapy); post-treatment BP and serum K+ values; concordance/discordance between ...
