A 31-year-old patient was followed for cystinuria, justifying CT scans. In 2006, a tissue mass of 3cm of the right adrenal gland, homogeneous, measured at 3.5cm in 2007 was noted. Blood pressure was 90/61mmHg, without orthostatic hypotension. During the clinical interview, no discomfort, sweat attack, headache, or palpitation was reported by the patient. Hormonal assays did not favor a primary hyperaldosteronism, or a hypercortisolism. Adrenal androgens were normal. 24h normetanephrines urinary excretion and metanephrines to creatinine ratio were elevated...

Midlife obesity is a risk factor for dementia development. Obesity has also been linked to hyperaldosteronism, and this can be modeled in rats by high fat (HF) feeding from weaning. Aldosterone, or activation of the mineralocorticoid receptor (MR) causes cerebrovascular injury in lean hypertensive rats. We hypothesized that rats fed a HF diet would show inward middle cerebral artery (MCA) remodeling that could be prevented by MR antagonism. We further proposed that the cerebral artery remodeling would be associated with white mater injury...

The adrenocortical gland undergoes structural and functional remodelling in the fetal and postnatal periods. After birth, the fetal zone of the gland undergoes rapid involution in favor of the definitive cortex, which reaches maturity with the emergence of the zona reticularis(zR) at the adrenarche. The mechanisms underlying the adrenarche, the process leading to pre-puberty elevation of plasma androgens in higher primates, remain unknown, largely due to lack of any experimental model. By following up fetal and definitive cortex cell lines in mice, we showed that activation of protein kinase A (PKA) signaling mainly impacts the adult cortex by stimulating centripetal regeneration, with differentiation and then conversion of the zona fasciculata into a functional zR...

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...

RATIONALE: Glycyrrhizin is the main active component of licorice. Licorice and glycyrrhizin induced hypertension has been widely reported, yet licorice and glycyrrhizin induced hypertensive crisis has been rarely known. PATIENT CONCERNS: The case of this report was a 47-year-old woman, who took 225 mg of glycyrrhizin daily for 3 years due to primary biliary cholangitis. She was found to have a dramatically elevated blood pressure of about 230/110 mmHg without a history of hypertension and was referred to the emergency department...

PURPOSE OF REVIEW: Current guidelines recommend adrenal venous sampling (AVS) to identify the surgically curable causes of hyperaldosteronism. In contrast with this recommendation, AVS remains markedly underutilized in clinical practice, which leads to deny curative adrenalectomy, to many patients with primary aldosteronism. The purpose of this review is to challenge the views that AVS is a technically challenging, invasive and risky procedure, which moreover, is difficult to interpret...

Adrenal vein development in utero occurs concurrently with the development of the inferior vena cava, the renal veins, and the gonadal veins. The embryologic formation of these veins involves communication of various venous systems. Although the left adrenal-renal vein complex is most commonly described as a shared emptying of the left adrenal vein and the left inferior phrenic vein into the left renal vein, there have been reports of numerous anatomic variations of this complex. In this report, we present a case of a rare variant of the left adrenal vein, in which the left adrenal vein empties into the left gonadal vein, which takes an atypical course superolateral to the left kidney...

Glucocorticoid-remediable aldosteronism is a hereditary form of primary hyperaldosteronism and the most common monogenic cause of hypertension. We present the case of a 24-year-old man with a family history of Conn's syndrome. Yet, in the index patient, classical characteristics of mineralocorticoid excess could be reversed by exogenous glucocorticoids.

Inactivated variants in CLCNKB gene encoding the basolateral chloride channel ClC-Kb cause classic Bartter syndrome characterized by hypokalemic metabolic alkalosis and hyperreninemic hyperaldosteronism. Here we identified two cBS siblings presenting hypokalemia in a Chinese family due to novel compound heterozygous CLCNKB mutations (c.848_850delTCT/c.1755A>G). Compound heterozygosity was confirmed by amplifying and sequencing the patient's genomic DNA. The synonymous mutation c.1755A>G (Thr585Thr) was located at +2bp from the 5' splice donor site in exon 15, further transcript analysis demonstrated that this single nucleotide mutation causes exclusion of exon 15 in the cDNA from the proband and his mother...

The angiotensin II (Ang II) type 2 receptor (AT2R) and the angiotensin-(1-7) (Ang-(1-7)) receptor (MasR) play a cardiovascular protective role by counter-regulating Ang II type 1 receptor (AT1R)-mediated effects, but whether this involves blunting of adrenocortical hormone secretion is unknown. We investigated the presence of AT1R, AT2R, and MasR in aldosterone-producing adenoma (APA), a condition featuring hyperaldosteronism, and in APA-adjacent tissue. The effect of Compound 21 (C21), an AT2R agonist, on CYP11B1 (cortisol synthase) and CYP11B2 (aldosterone synthase) gene expression in NCI-H295R and HAC15 cell lines, and in APA and APA-adjacent tissue, was also assessed using the AT1R antagonist irbesartan to ascertain the specificity of C21 effect...

Primary aldosteronism, a common cause of severe hypertension 1 , features constitutive production of the adrenal steroid aldosterone. We analyzed a multiplex family with familial hyperaldosteronism type II (FH-II) 2 and 80 additional probands with unsolved early-onset primary aldosteronism. Eight probands had novel heterozygous variants in CLCN2, including two de novo mutations and four independent occurrences of a mutation encoding an identical p.Arg172Gln substitution; all relatives with early-onset primary aldosteronism carried the CLCN2 variant found in the proband...

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...

Hyperaldosteronism, a common cause of hypertension, is strongly connected to Na+ , K+ , and Mg2+ dysregulation. Owing to its steroidal structure, aldosterone is an active transcriptional modifier when bound to the mineralocorticoid receptor (MR) in cells expressing the enzyme 11β-hydroxysteroid dehydrogenase 2, such as those comprising the aldosterone-sensitive distal nephron (ASDN). One such up-regulated protein, the ubiquitous serum and glucocorticoid regulated kinase 1 (SGK1), has the capacity to modulate the surface expression and function of many classes of renal ion channels, including those that transport Na+ (ENaC), K+ (ROMK/BK), Ca2+ (TRPV4/5/6), Mg2+ (TRPM7/6), and Cl- (ClC-K, CFTR)...

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...

A middle-aged woman with obesity, hyperlipidaemia and diet-controlled diabetes was referred for resistant hypertension. Her blood pressure (BP) was uncontrolled on five medications, including a diuretic. Physical exam revealed a systolic ejection murmur, and ECHO demonstrated moderate hypertrophy. Laboratory examination revealed elevated aldosterone level (20.7 ng/dL) and elevated aldosterone:renin ratio (41.4 (ng/dL)/(ng/mL/h)), meeting criteria for primary aldosteronism (PA), and confirmed by saline infusion testing...
