Abstract
Adrenal pathologies have variable clinical presentations and primary care providers should be aware of common and serious adrenal disorders. All adrenal masses require evaluation for malignancy, whether primary or metastatic, and all masses require evaluation for inappropriate hormonal secretion. In the event of adrenal insufficiency, the etiology of cortisol inadequacy must be identified and appropriately treated to prevent life-threatening complications.

Abstract
Few studies demonstrated a percentage decrease in the estimated glomerular filtration rate (eGFR) at a single time and the rate of hypoaldosteronism after adrenalectomy for primary aldosteronism (PA). Our aim was to investigate the evolution of renal function and the hypoaldosteronism risk after adrenalectomy for PA. Aldosterone, renin, eGFR, and electrolyte levels were determined before and at 1 week, 1, 3 and 6 months after unilateral adrenalectomy in 94 PA patients (40 men and 54 women). The main outcome was the postoperative eGFR decline using analysis of covariance with the preoperative eGFR as a covariate. eGFR decreased during first postoperative week compared to 3 months before surgery. During the first 6 months, eGFR remained stable at similar levels to the first week after surgery. Age (p=0.001), aldosterone levels (p=0.021) and eGFR 3 months before surgery (p+<+0.0001) had a significant correlation with eGFR during first postoperative week. High aldosterone levels at diagnosis were correlated with decline in renal function in the univariate model (p=0.033). In the multivariate analysis, aldosterone levels at diagnosis had a tendency to be an independent predictor of renal function after surgery (p=0.059). Postoperative biochemical hypoaldosteronism was diagnosed in 48% of the cases after adrenalectomy, but prolonged hyperkalemia occurred in only 4 cases (4.5%). Our findings showed a decrease of eGFR after unilateral adrenalectomy for PA. Additionally, aldosterone levels at diagnosis correlated with postoperative renal function. Postoperative biochemical hypoaldosteronism occurred in almost half of the patients, but prolonged hyperkalemia with fludrocortisone replacement was less frequent.

Abstract
RATIONALE AND OBJECTIVES Adrenal venous sampling (AVS) is the primary method for differentiating between primary aldosterone (PA) subtypes. The aim of study is to develop prediction models for subtyping of patients with PA using computed tomography (CT) radiomics and clinicobiochemical characteristics associated with PA. MATERIALS AND METHODS This study retrospectively enrolled 158 patients with PA who underwent AVS between January 2014 and March 2021. Neural network machine learning models were developed using a two-stage analysis of triple-phase abdominal CT and clinicobiochemical characteristics. In the first stage, the models were constructed to classify unilateral or bilateral PA; in the second stage, they were designed to determine the predominant side in patients with unilateral PA. The final proposed model combined the best-performing models from both stages. The model's performance was evaluated using repeated stratified five-fold cross-validation. We employed paired t-tests to compare its performance with the conventional imaging evaluations made by radiologists, which categorize patients as either having bilateral PA or unilateral PA on one side. RESULTS In the first stage, the integrated model that combines CT radiomic and clinicobiochemical characteristics exhibited the highest performance, surpassing both the radiomic-alone and clinicobiochemical-alone models. It achieved an accuracy and F1 score of 80.6% ± 3.0% and 74.8% ± 5.2% (area under the receiver operating curve [AUC] = 0.778 ± 0.050). In the second stage, the accuracy and F1 score of the radiomic-based model were 88% ± 4.9% and 81.9% ± 6.2% (AUC=0.831 ± 0.087). The proposed model achieved an accuracy and F1 score of 77.5% ± 3.9% and 70.5% ± 7.1% (AUC=0.771 ± 0.046) in subtype diagnosis and lateralization, surpassing the accuracy and F1 score achieved by radiologists' evaluation (p < .05). CONCLUSION The proposed machine learning model can predict the subtypes and lateralization of PA. It yields superior results compared to conventional imaging evaluation and has potential to supplement the diagnostic process in PA.

Abstract
Primary aldosteronism (PA), a significant and curable cause of secondary hypertension, is seen in 5-10% of hypertensive patients, with its prevalence contingent upon the severity of the hypertension. The principal aetiologies of PA include bilateral idiopathic hypertrophy (BIH) and aldosterone-producing adenomas (APAs), while the less frequent causes include unilateral hyperplasia, familial hyperaldosteronism (FH) types I-IV, aldosterone-producing carcinoma, and ectopic aldosterone synthesis. This condition, characterised by excessive aldosterone secretion, leads to augmented sodium and water reabsorption alongside potassium loss, culminating in distinct clinical hallmarks: elevated aldosterone levels, suppressed renin levels, and hypertension. Notably, hypokalaemia is present in only 28% of patients with PA and is not a primary indicator. The association of PA with an escalated cardiovascular risk profile, independent of blood pressure levels, is notable. Patients with PA exhibit a heightened incidence of cardiovascular events compared to counterparts with essential hypertension, matched for age, sex, and blood pressure levels. Despite its prevalence, PA remains frequently undiagnosed, underscoring the imperative for enhanced screening protocols. The diagnostic process for PA entails a tripartite assessment: the aldosterone/renin ratio (ARR) as the initial screening tool, followed by confirmatory and subtyping tests. A positive ARR necessitates confirmatory testing to rule out false positives. Subtyping, achieved through computed tomography and adrenal vein sampling, aims to distinguish between unilateral and bilateral PA forms, guiding targeted therapeutic strategies. New radionuclide imaging may facilitate and accelerate such subtyping and localisation. For unilateral adrenal adenoma or hyperplasia, surgical intervention is optimal, whereas bilateral idiopathic hyperplasia warrants treatment with mineralocorticoid antagonists (MRAs). This review amalgamates established and emerging insights into the management of primary aldosteronism.

Abstract
The adrenal glands drive physiologic homeostasis, with dysregulation in any direction causing multisystem dysfunction. Adrenal excess states include hyperaldosteronism which manifests with refractory hypertension and electrolyte abnormalities including hypernatremia and hypokalemia. Paragangliomas including pheochromocytoma can cause multisystem end-organ dysfunction due to catecholaminergic storm, which require rapid blood pressure control with phentolamine and identification of lesions amenable to surgical resection. Adrenal insufficiency states in contrast can result in hypotension and decompensation refractory to vasopressor administration, requiring adrenal supplementation via hydrocortisone.

Abstract
Primary hyperaldosteronism typically leads to resistant hypertension, hypokalemia, and metabolic alkalosis. Excess aldosterone secretion by the adrenal glands may lead to heart failure with preserved ejection fraction. Potassium-sparing diuretics and aldosterone antagonists directed to lower excess aldosterone levels may help treat the associated heart failure and lead to control of blood pressure, resulting in improved outcomes. We report a case of a 55-year-old male with poorly controlled hypertension and newly symptomatic heart failure with preserved ejection fraction in the setting of excess aldosterone activity and an adrenal adenoma suggesting primary aldosteronism-induced diastolic heart failure. The biochemical evaluation revealed elevated plasma aldosterone concentrations with low plasma renin activity, diuretic-induced hypokalemia, and metabolic alkalosis. A progressively enlarging left adrenal adenoma was found on abdominal imaging along with resistant hypertension despite the use of multiple antihypertensive medications. Medical management targeted to lower excess aldosterone levels with the use of aldosterone antagonists helped us achieve better blood pressure control and resolution of symptoms of diastolic dysfunction. Treating the underlying pathology helped us improve overt heart failure and may suggest that goal-directed therapy towards the inciting factors may potentially lead to a path to reverse the heart failure symptoms clinically.

Abstract
Plasma renin activity (PRA) is recommended as the first screening indicator for primary aldosteronism. Immunoassays and liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods have been developed for quantifying PRA, but the interchangeability across assays and laboratories was suboptimal, which predominantly related to the differences in the plasma incubation strategy. This study aims to establish and validate a designed comparison method based on LC-MS/MS. The sensitivity, matrix effect, precision, accuracy, and storage stability were validated according to the Clinical Laboratory Standard Institution (CLSI) C-62A guidelines. The plasma incubation procedure was optimized to achieve maximum PRA results. The short-term stability of PRA plasma was assessed at 4 °C and room temperature (RT) for specific time points. Differences from the baseline were calculated using a one-way analysis of variance. The designed comparison method for PRA measurement exhibits excellent performance characteristics. The results from the 2022 national external quality assessment scheme for PRA showed good consistency of the developed method with other LC-MS/MS methods (relative biases: -6.8% to 4.6%), which demonstrated the reliability of the established method. Two sets of generation buffers were optimized to maximize the renin activity. The acetate buffer was recommended to be used in laboratory practice due to better metrological sensitivity. PRA plasma is stable for one day at 4 °C and RT. In summary, a reliable, traceable, and reproducible LC-MS/MS method for determining PRA was well-established and validated. The recommended incubation protocol is hoped to reduce the discrepancy in Ang1 generation. The evaluated short-term stability for PRA plasma could provide flexibility in clinical practice.

Abstract
CONTEXT Primary aldosteronism (PA) screening relies on an elevated aldosterone to renin ratio with a minimum aldosterone level, which varies from 10 to 15 ng/dL (277 to 415.5 pmol/L) using immunoassay. AIM To evaluate intraindividual coefficient of variation (CV) of aldosterone and aldosterone to direct renin concentration ratio (A/DRC) and its impact on PA screening. METHODS A total of 671 aldosterone and DRC measurements were performed by the same chemiluminescence assays in a large cohort of 216 patients with confirmed PA and at least two screenings. RESULTS The median intraindividual CV of aldosterone and A/DRC was 26.8% and 26.7%. Almost 40% of the patients had at least one aldosterone level <15 ng/dL, 19.9% had at least two aldosterone levels <15 ng/dL and 16.2% had mean aldosterone levels <15 ng/dL. A lower cut-off of 10 ng/dL was associated with false negative rates for PA screening of 14.3% for a single aldosterone measurement, 4.6% for two aldosterone measurements and only 2.3% for mean aldosterone levels. Considering the minimum aldosterone, true positive rate of aldosterone thresholds was 85.7% for 10 ng/dL and 61.6% for 15 ng/dL. An A/DRC >2 ng/dL/µIU/mL had a true positive rate for PA diagnosis of 94.4% and 98.4% when based on one or two assessments, respectively. CV of aldosterone and A/DRC were not affected by sex, use of interfering anti-hypertensive medications, PA lateralization, hypokalemia, age and number of hormone measurements. CONCLUSION Aldosterone concentrations had a high CV in PA patients, which results in an elevated rate of false negative test in a single screening for PA. Therefore, PA screening should be based in at least two screenings with concomitant aldosterone and renin measurements.

Abstract
High blood pressure (BP) is not restricted to adults; children and adolescents may also be affected, albeit less frequently. Aside from unfavorable environmental factors, such as obesity and sedentary life leading to early-onset essential hypertension (HT), several secondary causes must be investigated in the occasional hypertensive child/adolescent. Endocrine causes are relevant and multiple, related to the pituitary, thyroid, parathyroid, gonads, insulin, and others, but generally are associated with adrenal disease. This common scenario has several vital components, such as aldosterone, deoxycorticosterone (DOC), cortisol, or catecholamines, but there are also monogenic disorders involving the kidney tubule that cause inappropriate salt retention and HT that simulate adrenal disease. Finally, a blood vessel disease was recently described that may also participate in this vast spectrum of pediatric hypertensive disease. This review will shed some light on the diagnosis and management of conditions, focusing on the most prevalent adrenal (or adrenal-like) disturbances causing HT.

Abstract
Primary aldosteronism (PA) is the most common form of secondary arterial hypertension, with a prevalence of approximately 20% in patients with resistant hypertension. In the last decade, somatic pathogenic variants in KCNJ5, CACNA1D, ATP1A1 and ATP2B3 genes, which are involved in maintaining intracellular ionic homeostasis and cell membrane potential, were described in aldosterone-producing adenomas (aldosteronomas). All variants in these genes lead to the activation of calcium signaling, the major trigger for aldosterone production. Genetic causes of familial hyperaldosteronism have been expanded through the report of germline pathogenic variants in KCNJ5, CACNA1H and CLCN2 genes. Moreover, PDE2A and PDE3B variants were associated with bilateral PA and increased the spectrum of genetic etiologies of PA. Of great importance, the genetic investigation of adrenal lesions guided by the CYP11B2 staining strongly changed the landscape of somatic genetic findings of PA. Furthermore, CYP11B2 staining allowed the better characterization of the aldosterone-producing adrenal lesions in unilateral PA. Aldosterone production may occur from multiple sources, such as solitary aldosteronoma or aldosterone-producing nodule (classical histopathology) or clusters of autonomous aldosterone-producing cells without apparent neoplasia denominated aldosterone-producing micronodules (non-classical histopathology). Interestingly, KCNJ5 mutational status and classical histopathology of unilateral PA (aldosteronoma) have emerged as relevant predictors of clinical and biochemical outcome, respectively. In this review, we summarize the most recent advances in the pathogenesis of PA and discuss their impact on clinical outcome.

Radiomics utilization to differentiate nonfunctional adenoma in essential hypertension and functional adenoma in primary aldosteronism. Sci Rep 2022; 12:8892. [PMID: 35614110 PMCID: PMC9132956 DOI: 10.1038/s41598-022-12835-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2021] [Accepted: 05/12/2022] [Indexed: 11/08/2022] Open
Abstract
We performed the present study to investigate the role of computed tomography (CT) radiomics in differentiating nonfunctional adenoma and aldosterone-producing adenoma (APA) and outcome prediction in patients with clinically suspected primary aldosteronism (PA). This study included 60 patients diagnosed with essential hypertension (EH) with nonfunctional adenoma on CT and 91 patients with unilateral surgically proven APA. Each whole nodule on unenhanced and venous phase CT images was segmented manually and randomly split into training and test sets at a ratio of 8:2. Radiomic models for nodule discrimination and outcome prediction of APA after adrenalectomy were established separately using the training set by least absolute shrinkage and selection operator (LASSO) logistic regression, and the performance was evaluated on test sets. The model can differentiate adrenal nodules in EH and PA with a sensitivity, specificity, and accuracy of 83.3%, 78.9% and 80.6% (AUC = 0.91 [0.72, 0.97]) in unenhanced CT and 81.2%, 100% and 87.5% (AUC = 0.98 [0.77, 1.00]) in venous phase CT, respectively. In the outcome after adrenalectomy, the models showed a favorable ability to predict biochemical success (Unenhanced/venous CT: AUC = 0.67 [0.52, 0.79]/0.62 [0.46, 0.76]) and clinical success (Unenhanced/venous CT: AUC = 0.59 [0.47, 0.70]/0.64 [0.51, 0.74]). The results showed that CT-based radiomic models hold promise to discriminate APA and nonfunctional adenoma when an adrenal incidentaloma was detected on CT images of hypertensive patients in clinical practice, while the role of radiomic analysis in outcome prediction after adrenalectomy needs further investigation.

Abstract
In patients with hypertension secondary to aldosterone secreting adrenal adenomas, medical and surgical treatments are both well described, with trans-catheter arterial embolization an uncommon form of therapy, currently. In patients where medical therapy has not provided sufficient response, and where surgical therapy is not deemed appropriate, trans-catheter arterial embolization of aldosteronomas has shown promise in a number of case series. We present the case of a 69-year-old man with hypertension refractory to medical therapy, and deemed not to be a surgical candidate for laparoscopic adrenalectomy. The patient underwent successful selective embolization of a functional adrenal adenoma, with sustained improvement in his prior hypertension, and without major complication. We conclude that trans-catheter embolization, when performed in the carefully selected suitable candidate, is a promising therapeutic option, and warrants a cohort study to assess long term outcomes.

Abstract
BACKGROUND Despite being the most common cause of secondary hypertension, prevalence of primary aldosteronism (PA) among patients with young-onset hypertension (YH - age of hypertension onset <40 years) remains poorly studied. OBJECTIVE We assessed the prevalence of PA in patients with YH referred for evaluation of secondary hypertension. DESIGN AND PATIENTS In this prospective, cross-sectional study, 202 patients with YH, visiting endocrine and cardiology clinics of All India Institute of Medical Sciences, India, were evaluated. MEASUREMENTS Primary aldosteronism was screened by measuring plasma aldosterone concentration (PAC) and direct renin concentration (DRC) and calculating aldosterone-to-renin ratio (ARR), followed by confirmatory saline infusion test (SIT) according to Endocrine Society Guideline. Those confirmed with post-SIT PAC >5 ng/dl underwent adrenal computed tomography (CT), followed by adrenal venous sampling (AVS). RESULTS Of 202 YH patients, 38 (18.8%) screened positive, and PA was confirmed in 36 (17.8%). The mean age was 43.9 ± 10.9 years, and median duration of hypertension was 10.5 (3.5-18) years. The prevalence of PA increased with grade of hypertension (8.1% in grade 1 to 37.1% in grade 3), number of antihypertensive medications (2.5% in those taking ≤1 to 50% in those taking ≥4 medications) and severity of hypokalaemia (0% in potassium >5 to 85.7% in potassium <3.5 mmol/L). The prevalence of PA by age of hypertension onset was highest in age group 30-39 years (31.3%). CONCLUSIONS There is a high prevalence and a long delay in diagnosis of PA among patients with YH, and YH should be considered as a separate high-risk category in PA screening algorithm.

Abstract
Treatment of choice in patients with unilateral aldosterone producing adenoma (APA) is adrenalectomy. Following surgery, most patients retain normal adrenal function, while some develop adrenal insufficiency (AI). To facilitate early detection and treatment of AI, we aimed to identify variables measured pre-operatively that are associated with post-operative AI. Variables obtained from 66 patients before and after surgery included anthropometrical data, clinical chemistry, endocrine work-up. LC–MS/MS steroid hormone profiles from tests before surgery (ACTH-stimulation, saline infusion, dexamethasone suppression) were obtained. Based on 78 variables, machine-learning methods were used in model fitting for classification and regression to predict ACTH-stimulated cortisol after surgery. Among the 78 variables, insulin concentration during pre-operative oral glucose tolerance test (OGTT) correlated positively, and dexamethasone suppressed glucocorticoids correlated negatively with ACTH-stimulated cortisol after surgery. Inclusion of LC–MS/MS measurements allowed construction of better models associated with the occurrence of AI in the training data, but did not allow reliable prediction in cross-validation. Our results suggest that glucocorticoid co-secretion (low insulin during pre-operative OGTT and insufficient suppression of glucocorticoids following dexamethasone) are correlated with the development of post-operative AI. Addition of steroid profiles improved the accuracy of prediction, but cross validation revealed lack of reliability in the prediction of AI.

Abstract
For several decades now, the analysis of steroids has been a key tool in the diagnosis and monitoring of numerous endocrine pathologies. Thus, the available methods used to analyze steroids in biological samples have dramatically evolved over time following the rapid pace of technology and scientific knowledge. This review aims to synthetize the advances in steroids' analysis, from classical approaches considering only a few steroids or a limited number of steroid ratios, up to the new steroid profiling strategies (steroidomics) monitoring large sets of steroids in biological matrices. In this context, the use of liquid chromatography coupled to mass spectrometry has emerged as the technique of choice for the simultaneous determination of a high number of steroids, including phase II metabolites, due to its sensitivity and robustness. However, the large dynamic range to be covered, the low natural abundance of some key steroids, the selectivity of the analytical methods, the extraction protocols, and the steroid ionization remain some of the current challenges in steroid analysis. This review provides an overview of the different analytical workflows available depending on the number of steroids under study. Special emphasis is given to sample treatment, acquisition strategy, data processing, steroid identification and quantification using LC-MS approaches. This work also outlines how the availability of steroid standards, the need for complementary analytical strategies and the improvement of calibration approaches are crucial for achieving complete steroidome quantification.

What Is the Most Common Cause of Secondary Hypertension?: An Interdisciplinary Discussion. Curr Hypertens Rep 2020; 22:101.

Abstract
PURPOSE OF REVIEW Traditional statements in medical textbooks pointed that 90 to 95% of cases of hypertension is essential or primary. However, secondary hypertension seems to be common in those patients with resistant forms of hypertension. Appropriate investigation and treatment may have prognostic impact but frequently hypertension remission did not occur raising concerns about the real meaning of secondary hypertension. Here, we provided an interdisciplinary and critical discussion comprising an endocrinologist, a nephrologist, and a cardiologist with expertise in resistant hypertension. We reviewed the literature approaching each one of the recognizable cause of hypertension. RECENT FINDINGS Recent studies pointed that the most common causes of secondary hypertension are those who overall responses to their treatments do not promote hypertension remission including obstructive sleep apnea (OSA), chronic kidney disease, renovascular hypertension and primary aldosteronism. The authors raised concerns regarding the lack of inclusion of obesity by several societies as a formal cause of hypertension considering not only the biologic plausibility but also the huge impact of weight loss therapies such as bariatric surgery on hypertension remission. In contrast, there is no discussion that a very rare condition-namely pheochromocytoma-is the most "typical" cause of hypertension by promoting hypertension remission in the majority of patients after surgical procedure. Hypertension is a complex condition with multiple environmental and genetics interactions. In clinical practice, it is challenging to prove causality in hypertension. Common conditions largely acceptable as causes of hypertension (OSA, chronic kidney disease, renovascular hypertension, and primary aldosteronism) frequently occur in a setting of an established hypertension background and therefore do not promote hypertension remission in a significant proportion of patients. If obesity becomes largely accepted by several societies as a secondary form of hypertension, this pandemic condition will be certainly the most common cause of hypertension.

Abstract
BACKGROUND Gitelman syndrome (GS) is an unusual, autosomal recessive salt-losing tubulopathy characterized by hypokalemic metabolic alkalosis, hypomagnesemia and hypocalciuria. It is caused by mutations in the solute carrier family 12 member 3 (SLC12A3) gene resulting in disordered function of the thiazide-sensitive NaCl co-transporter. To date, many types of mutations in the SLC12A3 gene have been discovered that trigger different clinical manifestations. Therefore, gene sequencing should be considered before determining the course of treatment for GS patients.
CASE SUMMARY A 55-year-old man was admitted to our department due to hand numbness and fatigue. Laboratory tests after admission showed hypokalemia, metabolic alkalosis and renal failure, all of which suggested a diagnosis of GS. Genome sequencing of DNA extracted from the patient’s peripheral blood showed a rare homozygous mutation in the SLC12A3 gene (NM_000339.2: chr16:56903671, Exon4, c.536T>A, p.Val179Asp). This study reports a rare homozygous mutation in SLC12A3 gene of a Chinese patient with GS.
CONCLUSION Genetic studies may improve the diagnostic accuracy of Gitelman syndrome and improve genetic counseling for individuals and their families with these types of genetic disorders

Abstract
AIMS Supranormal levels of aldosterone are associated with an increased cardiovascular risk in humans, and with accelerated atherosclerosis in animal models. Atherosclerosis is a low-grade inflammatory disorder, with monocyte-derived macrophages as major drivers of plaque formation. Monocytes can adopt a long-term pro-inflammatory phenotype after brief stimulation with microbial pathogens or endogenous atherogenic lipoproteins via a process termed trained immunity. In this study, we aimed to investigate whether aldosterone can induce trained immunity in primary human monocytes in vitro and explored the underlying mechanism. METHODS AND RESULTS We exposed human monocytes to aldosterone for 24 h, after which they were rested to differentiate into monocyte-derived macrophages for 5 days, and re-stimulated with toll-like receptor 2 and 4 ligands on day 6. We demonstrated that aldosterone augments pro-inflammatory cytokine production and reactive oxygen species production in monocyte-derived macrophages after re-stimulation, via the mineralocorticoid receptor. Fatty acid synthesis was identified as a crucial pathway necessary for this induction of trained immunity and pharmacological inhibition of this pathway blunted aldosterone-induced trained immunity. At the level of gene regulation, aldosterone promoted enrichment of the transcriptionally permissive H3K4me3 modification at promoters of genes central to the fatty acid synthesis pathway. CONCLUSION Aldosterone induces trained immunity in vitro, which is dependent on epigenetically mediated up-regulation of fatty acid synthesis. These data provide mechanistic insight into the contribution of aldosterone to inflammation, atherosclerosis, and cardiovascular disease.

Abstract
An adrenal incidentaloma is defined as an adrenal mass measuring at least 1 cm that is discovered surreptitiously in an imaging study done for reasons other than the evaluation of adrenal disease. The increase in the prevalence of adrenal incidentalomas has paralleled the increase in diagnostic imaging done for evaluation of other abdominal pathologies. However, most of these adrenal incidentalomas are benign non-hyperfunctioning adenomas. When an adrenal incidentaloma is discovered, the simultaneous presence of hypokalemia, metabolic alkalosis, mild hypernatremia, and mild to severe drug-resistant hypertension may alert a clinician to underlying primary hyperaldosteronism. We present a case of adrenal incidentaloma noted in a patient with end-stage renal disease on hemodialysis which presented a diagnostic challenge due to the correction of metabolic parameters with hemodialysis. The patient was found to have an aldosterone-producing adenoma based on an elevated aldosterone-to-renin ratio and was started on a mineralocorticoid antagonist.

Abstract
Primary hyperaldosteronism (PA) is one of the most common causes of hypertension that is amenable to surgical cure. Once a patient has a biochemical diagnosis of PA, workup should proceed with tumor lateralization to determine whether the patient has unilateral or bilateral disease. Tumor lateralization can be done with noninvasive imaging such as a CT or MRI. However, in older patients or in patients with non-lateralizing imaging, arteriovenous sampling (AVS) should be considered. If the patient has confirmed unilateral disease, options for surgical intervention include laparoscopic or, less commonly, open. Laparoscopic adrenalectomy for PA has been shown to be a safe and effective procedure that is associated with less morbidity compared to open adrenalectomy. Patients can either undergo a laparoscopic transabdominal adrenalectomy via a lateral (most common) or anterior approach or a retroperitoneoscopic adrenalectomy via a posterior approach. The majority of patients have complete biochemical success, defined as normalization of plasma aldosterone, renin and potassium levels and appropriate suppression with stimulation tests. Less than half of patients have complete clinical success, defined as normotensive with no antihypertensive medications. However, the majority of patients who do not have complete clinical success will have some improvement in their blood pressure and/or are able to decrease the number of antihypertensive medications that they require.

Abstract
Several studies suggest that variations in the concentration of plasma glycoproteins can influence cellular changes in a large number of diseases. In recent years, proton nuclear magnetic resonance (1H-NMR) has played a major role as an analytical tool for serum and plasma samples. In recent years, there is an increasing interest in the characterization of glycoproteins through 1H-NMR in order to search for reliable and robust biomarkers of disease. The objective of this review was to examine the existing studies in the literature related to the study of glycoproteins from an analytical and clinical point of view. There are currently several techniques to characterize circulating glycoproteins in serum or plasma, but in this review, we focus on 1H-NMR due to its great robustness and recent interest in its translation to the clinical setting. In fact, there is already a marker in H-NMR representing the acetyl groups of the glycoproteins, GlycA, which has been increasingly studied in clinical studies. A broad search of the literature was performed showing a general consensus that GlycA is a robust marker of systemic inflammation. The results also suggested that GlycA better captures systemic inflammation even more than C-reactive protein (CRP), a widely used classical inflammatory marker. The applications reviewed here demonstrated that GlycA was potentially a key biomarker in a wide range of diseases such as cancer, metabolic diseases, cardiovascular risk, and chronic inflammatory diseases among others. The profiling of glycoproteins through 1H-NMR launches an encouraging new paradigm for its future incorporation in clinical diagnosis.

Abstract
Background: Consistent evidence have demonstrated that patients with primary aldosteronism (PA) have higher risk of cardiovascular events to patients with essential hypertension (EH). Whether the long-term risk of mortality for PA patients is higher than EH patients is unclear. We aim to compare the long-term mortality of patients with PA to patients with EH. Methods: We searched PubMed, Embase, and Cochrane Central Register of Controlled Trials for eligible studies from inception to 14 Nov 2018. We combined the relative risks (RR) of each included study by random-effect model. The amount of between study heterogeneity was measured by the I2 statistic. Results: We totally included six studies with cohort design, including 3,039 PA and 45,495 EH patients. The pooled RRs for patients with PA were 1.97 (95%CI: 1.33, 2.91; P = 0.0007) for a follow-up of 3 years, 0.96 (95%CI: 0.75, 1.23; P = 0.76) for 5 years, 0.86 (95%CI: 0.51, 1.46) for 7.5 years, and 0.95 (95%CI: 0.61, 1.48; P = 0.58) for 10 years. For patients with aldosterone-producing adenomas (APA), evidence of lower risk of long-term mortality was observed. Our sensitivity analysis suggested our results were stable. Conclusions: Current evidence supported a higher risk of mortality for patients with primary aldosteronism at 3 years compared to patients with essential hypertension, however this risk no longer sustains as the follow-up time increased to 5 or more years. Patients with aldosterone-producing adenomas may have lower long-term mortality rate than patients with essential hypertension due to the better recovery of adrenalectomy.

Abstract
Increased hormonal secretion of aldosterone, cortisol, or catecholamines from an adrenal gland can produce a variety of undesirable symptoms, including hypertension, which may be the initial presenting symptom. Consequences of secondary hypertension can result in potential cardiovascular and cerebrovascular complications at higher rates than in those with essential hypertension. Once a biochemical diagnosis is confirmed, targeted pharmacotherapy can be initiated to improve hypertension and may be corrected with surgical intervention. Adrenalectomy can be curative and can reverse the risk of cardiovascular sequelae once blood pressure control is achieved. This article discusses perioperative and operative considerations of adrenal causes of hypertension.

Abstract
Insight into the health-related quality of life (HRQoL) impact of adrenocortical carcinoma (ACC) is important. The disease and its treatment options potentially have an impact on HRQoL. For patients with limited survival, HRQoL research is of utmost importance. We will therefore provide an overview of HRQoL studies in patients with ACC. We found six studies that measured HRQoL in 323 patients with ACC (3 cross-sectional, 1 cohort, 2 trials), all indicating a reduced HRQoL compared to the general population. The FIRMACT trial found that HRQoL of patients with ACC was reduced compared to the general population, and that chemotherapy-mitotane further reduced HRQoL even though survival improved. Clinical aspects of the disease, including cortisol and aldosterone production and adrenal insufficiency have shown great impact on HRQoL in benign disease, even after the recovery of hormonal status. However, the impact of malignant adrenal disease and treatment options on HRQoL including adrenalectomy, radiotherapy, mitotane therapy, and chemotherapy have not been sufficiently studied in patients with ACC. Although the number of HRQoL studies in patients with ACC is limited, the existing literature does indicate that ACC has a large impact on patients' HRQoL, with disease specific aspects. Further HRQoL research in patients with ACC is essential to improve patient-centered care, preferably by using an ACC-specific HRQoL questionnaire.

Abstract
RATIONALE Primary aldosteronism (PA) comprises 2 main subtypes: unilateral aldosterone-producing adenoma (APA) and idiopathic hyperaldosteronism or named as bilateral adrenal hyperplasia (BAH). An accurate discrimination between APA and BAH is crucial because the former is treated with adrenalectomy (ADX) and the latter is primarily by aldosterone antagonists. We report a case of idiopathic hyperaldosteronism characterized by BAH. PATIENT CONCERNS A 46-year-old woman had experienced a paroxysmal elevation of blood pressure for the past 2 months, along with an intermittent headache and mild occipital swelling and pain. DIAGNOSES We performed clinical, laboratory, and imaging tests, as well as bilateral adrenal vein sampling (AVS) on this patient. Specifically, computed tomography scan and magnetic resonance imaging were used to characterize the properties of bilateral adrenal adenoma. Additionally, bilateral AVS was performed to distinguish unilateral from bilateral adrenal abnormality in this patient. INTERVENTIONS After oral administration of aldosterone antagonists, her blood pressure and potassium levels returned to normal ranges and her condition improved. OUTCOMES Following differential diagnosis, screening, functional tests, a variety of imaging studies, and bilateral adrenal vein sampling (AVS) typing, she was finally diagnosed with idiopathic hyperaldosteronism. LESSONS For PA patients with lack of typical hypertension and hypokalemia performance, early identification and accurate diagnosis are of great significance for improving the prognosis of BAH. AVS plays an important role in the classification of PA subtype, especially for the cases with bilateral lesions. In regard to patients with rare bilateral adrenocortical adenoma-type aldosteronism, AVS plays a key role in choosing the appropriate treatment regimen.

Abstract
CONTEXT Primary aldosteronism (PA) is the most common cause of endocrine hypertension (HT). HT remission (defined as blood pressure <140/90 mm Hg without antihypertensive drugs) has been reported in approximately 50% of patients with unilateral PA after adrenalectomy. HT duration and severity are predictors of blood pressure response, but the prognostic role of somatic KCNJ5 mutations is unclear. OBJECTIVE To determine clinical and molecular features associated with HT remission after adrenalectomy in patients with unilateral PA. METHODS We retrospectively evaluated 100 patients with PA (60 women; median age at diagnosis 48 years with a median follow-up of 26 months). Anatomopathological analysis revealed 90 aldosterone-producing adenomas, 1 carcinoma, and 9 unilateral adrenal hyperplasias. All patients had biochemical cure after unilateral adrenalectomy. KCNJ5 gene was sequenced in 76 cases. RESULTS KCNJ5 mutations were identified in 33 of 76 (43.4%) tumors: p.Gly151Arg (n = 17), p.Leu168Arg (n = 15), and p.Glu145Gln (n = 1). HT remission was reported in 37 of 100 (37%) patients. Among patients with HT remission, 73% were women (P = 0.04), 48.6% used more than three antihypertensive medications (P = 0.0001), and 64.9% had HT duration <10 years (P = 0.0015) compared with those without HT remission. Somatic KCNJ5 mutations were associated with female sex (P = 0.004), larger nodules (P = 0.001), and HT remission (P = 0.0001). In multivariate analysis, only a somatic KCNJ5 mutation was an independent predictor of HT remission after adrenalectomy (P = 0.004). CONCLUSION The presence of a KCNJ5 somatic mutation is an independent predictor of HT remission after unilateral adrenalectomy in patients with unilateral PA.

Abstract
Introduction: The captopril challenge test (CCT) is the major confirmatory test for primary
aldosteronism (PA), and frequently carried out because of its convenience.
However, it presents false-negative results with a certain probability, and
as there are many criteria for CCT, it is not concluded yet which criteria
to use. Materials and methods: A total of 71 PA patients were evaluated. We compared CCT-positive and
CCT-negative patients in the following three criteria: plasma
aldosterone/renin ratio (ARR) >200 after the CCT (criterion 1); plasma
aldosterone concentration (PAC) >120 pg/ml after the CCT (criterion 2);
and PAC suppression <30% of PAC before CCT (criterion 3). Results: The positive rate was 70.4%, 64.8% and 54.9% for criterion 1, criterion 2 and
criterion 3, respectively. With criterion 1, the baseline plasma renin
activity was lower, thus baseline ARR was higher in CCT-positive patients.
With criterion 2, PAC was higher and estimated sodium intake and K were
lower in CCT-positive patients. With criterion 3, K and PAC were lower in
CCT-positive patients. Although it was not significant, in the patients with
high sodium intake, the positive rate of criterion 1 was higher than that of
the other criteria. Conclusions: ARR>200 is the valuable criterion for the diagnosis of PA.

Abstract
INTRODUCTION As part of the renin-angiotensin-aldosterone system (RAAS), aldosterone is key to the pathology of cardiovascular and renal diseases, leading to end-organ damage and cardiovascular death. Because of different aetiology and metabolism, pharmacotherapy in adults shows only limited transferability to children. Comprehensive investigations of humoral parameters, their precursors, and metabolites are necessary to establish a more rational and safe therapy in children. The LENA (Labeling of Enalapril from Neonates up to Adolescents) project aims to generate these missing data in neonates up to adolescents and provide insight into the maturing RAAS. METHODS A HRMS (high-resolution mass spectrometry) assay was developed, utilizing blank serum depleted of the endogenous aldosterone, its precursor, 18-hydroxycorticosterone, and its main metabolite, tetrahydroaldosterone. A TOF-MS (time-of-flight-mass spectrometry) scan run in parallel with the simultaneous determination of all three analytes enriches the acquired data. Validation of aldosterone was conducted according to EMA and FDA bioanalytical guidelines. RESULTS Using the Sciex TripleTOF 6600, a reliable determination in 50 µL serum was successfully shown. Appropriate calibration ranges from 19.53 pg/mL for aldosterone, 39.06 pg/mL for 18-hydroxycorticosterone, and 78.13 pg/mL for tetrahydroaldosterone to 2500 pg/mL were established to ensure the applicability in diseased paediatric patients. Between-run accuracy and precision for aldosterone ranged between -1.21 and -6.99 % and 2.07 and -10.22 %, respectively, confirming compliance with international guidelines. CONCLUSION A simultaneous bioanalytical LC-HRMS assay for the determination of the biomarker aldosterone, its precursor, and main metabolite, utilizing 50 µL serum, was successfully established. This assay facilitates insight into the maturing RAAS from neonates up to adolescents.

Rates of abnormal aldosterone/renin ratio in African-origin compared to European-origin patients: A retrospective study. Clin Endocrinol (Oxf) 2019; 90:528-533. [PMID: 30575078 DOI: 10.1111/cen.13920] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2018] [Revised: 12/11/2018] [Accepted: 12/18/2018] [Indexed: 12/01/2022]
Abstract
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 aldosterone/renin ratio (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. RESULTS Aldosterone/renin ratio was available in 1473 patients, and abnormal in 374 (25.4%). Abnormal ARR was observed in 305/1349 (22.6%) of European-origin and 69/124 (55.6%) of African-origin patients (P < 0.001). Among those with abnormal ARR, hypokalaemia (<3.5 mmol/L) was documented on at least one occasion in 171/305 (56.1%) European-origin and 43/69 (62.3%) African-origin patients (P = 0.35). Median (range) IVS was 1.57 (0.78-2.80) cm in African-origin and 1.20 (0.69-2.18) cm in European-origin patients (P < 0.002); IVS did not correlate with aldosterone or ARR however. Adrenal adenoma was identified in 41/170 (24.1%) of European-origin and 4/29 (13.7%) African-origin patients (P = 0.15), while hyperplasia was identified in 35/170 (20.5%) of European and 8/29 (27.5%) African patients (P = 0.39). CONCLUSION In summary, ARR was abnormal in 55.6% of African-origin patients screened at an Irish hospital. Rates of hypokalaemia were similar between European-origin and African-origin patients. These findings have implications for the use of current screening guidelines for ARR in African-origin patients and also for the mechanistic role of aldosterone in hypertensive complications in African-origin patients.

Abstract
RATIONALE Cases of adrenocortical hyperfunction combined with primary aldosteronism have been reported in the literature, and the underlying mechanism involves the secretion of aldosterone and glucocorticoids by a tumor or an adenoma. However, adrenocortical hypofunction and coexisting primary aldosteronism have not been reported until now. Herein, we report a case of adrenocortical hypofunction combined with primary aldosteronism. PATIENT CONCERNS A 66-year-old Chinese woman with rheumatoid arthritis who had been diagnosed with secondary adrenal insufficiency and was taking prednisone acetate tablets for replacement treatment presented to our department. She also had type 2 diabetes mellitus, osteoporosis, bilateral knee osteoarthritis, and lumbar vertebral compression fracture. She had previously developed tuberculosis, which had been cured. DIAGNOSIS The cortisol and adrenocorticotropic hormone rhythm indicated cortisol dysfunction in the patient. A 64-slice computed tomography and magnetic resonance imaging both showed bilateral adrenal hyperplasia. A postural stimulation test indicated a high level of aldosteronism and a high aldosterone-to-renin ratio (ARR, supine position: aldosterone 1788.73 pg/mL, ARR 146.62; upright position: aldosterone 2916.21 pg/mL, ARR 92.29). The captopril test showed the aldosterone level decreased by 364.70 pg/mL 1 hour after administration of captopril (from 2153.28 to 1788.58 pg/mL). The decline in aldosterone level was approximately 16.90% (i.e., <30%), and the ARR was still >40. Based on the above-mentioned findings, we diagnosed the patient with adrenocortical hypofunction with primary aldosteronism. INTERVENTIONS We administered spironolactone 20 mg twice daily and continued the glucocorticoid replacement therapy. OUTCOMES One week after diagnosis, the patient had an aldosterone level of 2201.16 pg/mL, plasma renin activity of 3.88 ng/mL/h, and an ARR of 56.7 (upright position). Her blood pressure was maintained within the normal range. LESSONS Although adrenocortical hypofunction with primary aldosteronism is rare, cases of primary aldosteronism complicated with hypercortisolism are occasionally encountered. Hence, whenever possible, we recommend testing both aldosterone and cortisol levels in all patients with adrenal dysfunction.

Abstract
The review is devoted to the consideration of genetic determination and pathophysiology of one of the forms of hypertensive disease known as low-renin hypertension. At frst glance, the development of low-renin hypertension is “unnatural”, as renin, as a key enzyme of the renin-angiotensin system, which plays an important role in the development of hypertensive disease, is suppressed in low-renin hypertension. At the same time, the most important drugs actual in the treatment of hypertensive disease belong to the renin-angiotensin system blockers. This contradiction was resolved by a study of genetic and pathophysiological mechanisms of hypertension in some groups of patients with characteristic symptoms bringing these people together. Genetic studies of some recent decades using both family analysis and modern molecular genetic technologies have revealed the main mechanisms underlying low-renin hypertension, which can be classifed as certain syndromes with well-defned genetic and clinical features. These syndromes include cases of sporadically occurring somatic mutations in the cells of the adrenal cortex, which begin to produce aldosterone in increased amounts. Also, several oligogenic forms of low-renin hypertension were studied, some of which are associated with the hyperproduction of aldosterone, but in the others the development of low-renin hypertension was associated with mutations of genes involved in regulation of the functioning of the kidney ion channels. The discovery of some types of arterial hypertension with known mechanisms of their development is of paramount importance for medicine, as it allows for targeted efective therapy and in some cases for achieving a complete cure. However, the main contingent of patients with low-renin hypertension belongs to cases with unexplained etiology, as their development is associated with polygenic systems and with a signifcant influence of numerous environmental factors. The study of genetic and physiological mechanisms of various forms of low-renin arterial hypertension provides a good example of how penetration into the intimate mechanisms of the blood pressure regulation in each personal case makes it possible to identify some specifc syndromes and establish its fnal causes. It seems that progress in understanding the causes and mechanisms of essential hypertension lies along this way.

Abstract
As diagnostic techniques have advanced, primary aldosteronism (PA) has emerged as the most common cause of secondary hypertension. The excess of aldosterone caused by PA resulted in not only cardiovascular complications, including coronary artery disease, myocardial infarction, arrhythmia, and heart failure, but also cerebrovascular complications, such as stroke and transient ischemic attack. Moreover, PA is associated more closely with these conditions than is essential hypertension. In this review, we present up-to-date findings on the association between PA and cerebrovascular diseases.

Abstract
CONTEXT Adrenal venous sampling (AVS) with or without adrenocorticotropic hormone (ACTH) stimulation is the test of choice to identify patients with a surgically curable subtype of primary aldosteronism (PA). Whether AVS with ACTH stimulation is more effective than AVS without ACTH stimulation remains controversial. OBJECTIVE To compare the effectiveness of AVS with ACTH stimulation and AVS without ACTH stimulation in patients with PA. METHODS The Cochrane Library, PubMed, Embase, and Web of Science databases were searched to identify relevant articles. All cohort studies comparing the 2 techniques (AVS with ACTH stimulation and AVS without ACTH stimulation in patient with PA) were included in the analysis. RESULTS A total of 14 studies met the inclusion criteria, and they were analyzed. AVS with ACTH stimulation did not significantly reduce the number of incorrect lateralization more than AVS without ACTH stimulation in patients with PA [OR: 0.76, 95% confidence interval (CI): 0.36, 1.59; P=0.47]. AVS with ACTH stimulation significantly reduced the number of unsuccessful cannulations of both adrenal veins more than AVS without ACTH stimulation in patients with PA (OR: 0.26, 95% CI: 0.17, 0.40; P<0.00001). For subgroup analyses, it also significantly reduced the number of unsuccessful cannulations of left adrenal vein and right adrenal vein (OR: 0.14, 95% CI: 0.06, 0.33; P<0.00001 and OR: 0.30, 95% CI: 0.12, 0.71; P=0.007, respectively). CONCLUSION AVS with ACTH stimulation can significantly reduce the number of unsuccessful cannulations, without significantly reducing the number of incorrect lateralization. Further studies are still needed to verify these findings.

Abstract
This review summarizes key knowledge regarding the development, growth, and growth disorders of the adrenal cortex from a molecular perspective. The adrenal gland consists of two distinct regions: the cortex and the medulla. During embryological development and transition to the adult adrenal gland, the adrenal cortex acquires three different structural and functional zones. Significant progress has been made in understanding the signaling and molecules involved during adrenal cortex zonation. Equally significant is the knowledge obtained regarding the action of peptide factors involved in the maintenance of zonation of the adrenal cortex, such as peptides derived from proopiomelanocortin processing, adrenocorticotropin and N-terminal proopiomelanocortin. Findings regarding the development, maintenance and growth of the adrenal cortex and the molecular factors involved has improved the scientific understanding of disorders that affect adrenal cortex growth. Hypoplasia, hyperplasia and adrenocortical tumors, including adult and pediatric adrenocortical adenomas and carcinomas, are described together with findings regarding molecular and pathway alterations. Comprehensive genomic analyses of adrenocortical tumors have shown gene expression profiles associated with malignancy as well as methylation alterations and the involvement of miRNAs. These findings provide a new perspective on the diagnosis, therapeutic possibilities and prognosis of adrenocortical disorders.

Abstract
Besides ultrasound and nuclear medicine techniques, computed tomography (CT) and magnetic resonance imaging (MRI) are commonly used to examine adrenal lesions in both symptomatic and asymptomatic patients. Some adrenal lesions have characteristic radiological features. If an adrenal nodule is discovered incidentally, determining whether the lesion is benign or malignant is of great importance. According to their biological behavior, lesions can be divided into benign (mainly: adenoma, hyperplasia, pheochromocytoma, cyst, hemorrhage, cystic lymphangioma, myelolipoma, hemangioma, ganglioneuroma, teratoma) and malignant (mainly: metastases, adrenal cortical carcinoma, neuroblastoma, lymphoma) conditions. In this paper, we review CT/MRI findings of common adrenal gland lesions.

Abstract
This review article proposes a model of integrative care for cardiovascular patients in institutional settings. We review relevant historic and contemporary examples of medical-chiropractic cooperation and a brief review of the literature illustrating the clinical benefits of chiropractic care for patients with cardiovascular disease. The groundwork proposes a distinct research and clinical practice model incorporating the doctor of chiropractic (D.C.) as a synergistic partner with the medical cardiologist coined the Kaleidoscope Model of Integrative Care (KM). While a traditional kaleidoscope does not alter the nature of light itself, the observer does see the 'raw data' of colors and shapes, wavelengths, etc. contained within the "potential" of the light itself; left unrecognized, even subtle re-orientations of the instrument changes the perspective. Similarly, the KM is intended as a conduit for slight reorientations to traditional medical-chiropractic-patient hierarchies, thus creating new treatment options and generating robust changes in inter-professional perception of the patient's condition(s) and treatment options. It is hoped that this model will not only serve future patients within hospitals, but that institutions will serve as incubators for better collaboration and research among the majority of free-standing medical and chiropractic practices ultimately benefitting the patient with cardiovascular disease.

Abstract
Secondary osteoporosis resulting from specific clinical disorders may be potentially reversible, and thus continuous efforts to find and adequately treat the secondary causes of skeletal fragility are critical to ameliorate fracture risk and to avoid unnecessary treatment with anti-osteoporotic drugs. Among the hyperfunctional adrenal masses, Cushing's syndrome, pheochromocytoma, and primary aldosteronism are receiving particularly great attention due to their high morbidity and mortality mainly by increasing cardiovascular risk. Interestingly, there is accumulating experimental and clinical evidence that adrenal hormones may have direct detrimental effects on bone metabolism as well. Thus, the present review discusses the possibility of adrenal disorders, especially focusing on pheochromocytoma and primary aldosteronism, as secondary causes of osteoporosis.
