Clinical characteristics of primary aldosteronism screened from Chinese patients with hypertension: The China primary aldosteronism prospective study. J Clin Hypertens (Greenwich) 2024. [PMID: 39037171 DOI: 10.1111/jch.14874] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 05/28/2024] [Accepted: 07/09/2024] [Indexed: 07/23/2024]
Abstract
We investigated the clinical characteristics of primary aldosteronism (PA) screened from patients with hypertension in China. The participants were hypertensive patients who were suspected of PA and registered in the China Primary Aldosteronism Prospective Study. Plasma aldosterone-to-renin ratio (ARR) was used as the screening test. In patients screened positive for PA, that is, an ARR exceeding the thresholds and plasma aldosterone concentration (PAC) > 100 pg/mL, a confirmatory test was performed for diagnosis. Patients with PA underwent a CT scan and adrenal venous sampling for subtyping. Of the 1497 screened patients, 754 (50.4%) had an ARR exceeding the diagnostic threshold and 637 (84.5% of those eligible) were registered. These registered hypertensive patients with suspected PA had a mean (standard deviation) age of 52.6 ± 12.1 years, and included 442 (58.6%) women. In multiple stepwise logistic regression, the significant odds ratios for the presence of diagnosed (n = 490) versus suspected and non-diagnosed PA (n = 147) were 4.54 (95% CI: 2.78-7.39) for a history of hypokalemia, 0.79 (95% CI: 0.64-0.98) for a 0.9 mmol/l higher serum total cholesterol, and 2.25 (95% CI: 1.63-3.10) for a doubling of PAC in the supine or standing/sitting position. In multiple stepwise logistic regression, the significant odds ratios for the presence of unilateral (n = 135) versus bilateral PA (n = 53) were 3.04 (95% CI: 1.90-4.87) for a 0.4 mmol/l lower minimum serum potassium concentration and 1.86 (95% CI: 1.20-2.86) for a 0.3 mmol/l higher serum high-density lipoprotein cholesterol. PA might be a biochemical continuum in the adrenal hypersecretion of aldosterone as well as hypokalemia.

Abstract
Secondary hypertension in the elderly poses many challenges and requires a comprehensive diagnostic and management approach. This review explores the prevalence, diagnostic strategies, and treatment modalities for secondary hypertension in elderly patients, focusing on etiologies including primary aldosteronism, renal vascular disease, renal parenchymal disease, obstructive sleep apnea, thyroid disorders, Cushing's syndrome, pheochromocytomas and paragangliomas, and drug-induced hypertension. Key considerations include age-related changes in physiology and atypical presentations of underlying conditions necessitating thorough screening with a combination of clinical evaluation, laboratory tests, and imaging studies. Collaboration among healthcare providers is essential to ensure a timely diagnosis and personalized management tailored to the unique needs of elderly patients. Further research is needed to address knowledge gaps and optimize clinical strategies for managing secondary hypertension in this population.

Abstract
CONTEXT Primary aldosteronism (PA) leads to kidney function deterioration after treatment, but the effects of the estimated glomerular filtration rate (eGFR) dip following adrenalectomy and its long-term implications are unclear. OBJECTIVE This study aims to examine eGFR dip in patients with unilateral PA (uPA) after adrenalectomy and clarify their long-term prognosis. METHODS This multicenter prospective population-based cohort study, enrolled patients with uPA who underwent adrenalectomy. Patients were divided into 4 groups based on their eGFR dip ratio. Outcomes investigated included mortality, cardiovascular composite events, and major adverse kidney events (MAKEs). RESULTS Among 445 enrolled patients, those with an eGFR dip ratio worse than -30% (n = 74, 16.6%) were older, had higher blood pressure, higher aldosterone concentration, and lower serum potassium levels. During 5.0 ± 3.6 years of follow-up, 2.9% died, 14.6% had cardiovascular composite events, and 17.3% had MAKEs. The group with eGFR dip worse than -30% had a higher risk of MAKEs (P < .001), but no significant differences in mortality (P = .295) or new-onset cardiovascular composite outcomes (P = .373) were found. Multivariate analysis revealed that patients with an eGFR dip ratio worse than -30% were significantly associated with older age (odds ratio [OR], 1.04), preoperative eGFR (OR, 1.02), hypokalemia (OR, 0.45), preoperative systolic blood pressure (OR, 1.03), and plasma aldosterone concentration (OR, 0.99). CONCLUSION Within 5 years post adrenalectomy, 17.3% of patients had reduced kidney function. Notably, individuals with an eGFR dip ratio worse than -30% faced higher MAKE risks, underscoring the need to monitor kidney function in PA patients after surgery.

Abstract
OBJECTIVES The correlation of the changes of estimated glomerular filtration rate (eGFR) with long-term cardiovascular complications in patients with primary aldosteronism (PA) following mineralocorticoid receptor antagonists (MRA) treatment remains ambiguous. This prospective study aims to determine factors associated with all-cause mortality and de novo cardiovascular events of PA patients against the eGFR-dip. METHODS A total of 208 newly diagnosed PA patients were enrolled from January 2017 to January 2019. MRA was administered with at least a 6-month follow-up. The 'eGFR-dip' was defined as the difference between eGFR at 6 months after MRA treatment and respective baseline eGFR divided by the baseline eGFR. RESULTS After a mean 5.7 years follow-up, an eGFR-dip more than 12%, which was detected in 99 (47.6%) of the 208 patients, was a significant independent risk factor predicting composite outcomes (all-cause mortality, de-novo three-point major adverse cardiovascular events, and/or congestive heart failure). Multivariable logistic regression showed that age [odds ratio (OR), 0.94; P = 0.003], pretreatment plasma aldosterone concentration (PAC; OR, 0.98; P = 0.004), and initial eGFR (OR, 0.97; P < 0.001) had a positive linkage with the eGFR-dip more than 12%. CONCLUSIONS Nearly half of PA patients had an eGFR-dip more than 12% after 6 months of MRA treatment. They had a higher incidence of all-cause mortality and de novo cardiovascular events. Elder age, higher pretreatment PAC, or higher initial eGFR could be associated with an elevated risk of an eGFR-dip more than 12%.

Abstract
BACKGROUND AND AIMS This study explored the association between urinary liver-type fatty acid-binding protein to creatinine (uL-FABP-cre) ratio and postoperative clinical failure in unilateral primary aldosteronism (PA) patients undergoing adrenalectomy. MATERIALS AND METHODS Data from the Taiwan Primary Aldosteronism Investigation Group database were analyzed, including patients with unilateral PA who had adrenalectomy between December 2015 and October 2018. Statistical methods included generalized additive modeling, logistic regression analysis, net reclassification improvement (NRI), and the C statistic. RESULTS In the study cohort of 131 patients (mean age 52.3 ± 10.8 years; 43.5% male), 117 achieved clinical success, while 14 experienced clinical failure. A uL-FABP-cre ratio ≥5 predicted clinical failure (odds ratio: 6.22, p = 0.005). Subgroup analysis revealed its efficacy in predicting clinical failure in patients with BMI ≥ 24 kg/m2, normokalemia, or <5 years of hypertension. Furthermore, incorporating uL-FABP-cre ratio into the Primary Aldosteronism Surgical Outcome (PASO) score significantly improved predictive ability. The addition increased the C statistic from 0.671 to 0.762 (p < 0.01) and improved category-free NRI by 0.675 (p = 0.014). CONCLUSION A uL-FABP-cre ratio ≥5 accurately predicted clinical failure post-adrenalectomy in unilateral PA, enhancing PASO score's identification of high-risk patients for postoperative clinical failure.

Prognostic value of contralateral suppression on kidney function after surgery in patients with primary aldosteronism. Clin Endocrinol (Oxf) 2023; 98:306-314.

Abstract
BACKGROUND AND OBJECTIVE Adrenalectomy for primary aldosteronism (PA) has been associated with decreased kidney function after surgery. It has been proposed that elimination of excess aldosterone unmasks an underlying failure of the kidney function. Contralateral suppression (CLS) is considered a marker of aldosterone excess and disease severity, and the purpose of this study was to assess the hypothesis that CLS would predict change in kidney function after adrenalectomy in patients with PA. DESIGN AND PATIENTS Patients with PA referred for adrenal venous sampling (AVS) between May 2011 and August 2021 and who were subsequently offered surgical or medical treatment were eligible for the current study. RESULTS A total of 138 patients were included and after AVS 85/138 (61.6%) underwent adrenalectomy while 53/138 (38.4%) were treated with MR-antagonists. In surgically treated patients the estimated glomerular filtration rate (eGFR) was reduced by 11.5 (SD: 18.5) compared to a reduction of 5.9 (SD: 11.5) in medically treated patients (p = .04). Among surgically treated patients, 59/85 (69.4%) were classified as having CLS. After adrenalectomy, patients with CLS had a mean reduction in eGFR of 17.5 (SD: 17.6) compared to an increase of 1.8 (SD: 12.8) in patients without CLS (p < .001). The association between CLS and change in kidney function remained unchanged in multivariate analysis. Post-surgery, 16/59 (27.1%) patients with CLS developed hyperkalemia compared to 2/26 (7.7%) in patients without CLS (p = .04). CONCLUSION This retrospective study found that CLS was a strong and independent predictor of a marked reduction of eGFR and an increased risk of hyperkalemia after adrenalectomy in patients with PA.

Cortisol-producing adenoma-related somatic mutations in unilateral primary aldosteronism with concurrent autonomous cortisol secretion: their prevalence and clinical characteristics. Eur J Endocrinol 2022; 187:519-530.

Abstract
OBJECTIVE Concurrent autonomous cortisol secretion (ACS) in patients with primary aldosteronism (PA) is being reported more frequently. Several somatic mutations including PRKACA, GNAS, and CTNNB1 were identified in cortisol-producing adenomas (CPAs). The presence of these mutations in unilateral PA (uPA) patients concurrent with ACS (uPA/ACS) is not well known. This study aimed to investigate the prevalence of these mutations and their clinical vs pathological characteristics in uPA/ACS. DESIGN This is a retrospective cohort study. METHODS Totally 98 uPA patients from the Taiwan Primary Aldosteronism Investigation registry having overnight 1-mg dexamethasone suppression test (DST) and adrenalectomy from 2016 to 2018 were enrolled. Their adrenal tumors were tested for PRKACA, GNAS, and CTNNB1 mutations. RESULTS 11 patients had CPA-related mutations (7 PRKACA and 4 GNAS). The patients carrying these mutations had higher post-DST cortisol (5.6 vs 2.6 μg/dL, P = 0.003) and larger adenoma (2.2 ± 0.3 vs 1.9 ± 0.7 cm, P = 0.025). Adenomas with these mutations had a higher prevalence of non-classical uPA (72.7% vs 26.3%, P = 0.014). Numerically, slightly more complete clinical success of uPA patients with these mutations was noticed after adrenalectomy, although it was statistically non-significant. Post-DST cortisol levels, adenoma size >1.9 cm, and the interaction of adenoma size >1.9 cm with potassium level were found to be associated with the presence of these mutations. CONCLUSION Our study showed that CPA-related mutations were detected in 36.7% of uPA/ACS adenomas. The presence of these mutations was associated with higher post-DST cortisol levels, larger adenoma sizes, and a high percentage of non-classical uPA. However, these mutations did not significantly affect the clinical and biochemical outcomes after adrenalectomy of uPA/ACS patients but they showed a better trend.

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
OBJECTIVES Decreased glomerular filtration rate has been reported in patients with primary aldosteronism after unilateral adrenalectomy. Glomerular hyperfiltration has been assumed to mask the preoperative subtle renal impairment. In this study, we investigated predictors for decreased estimated glomerular filtration rate after adrenalectomy in patients with primary aldosteronism. METHODS From January 2006 through September 2018, 328 patients with confirmatory diagnoses of primary aldosteronism received unilateral laparoscopic adrenalectomy and subsequent follow-up for 12 months. We prospectively collected related parameters of the clinical outcomes and renal function to identify predictors of renal function impairment at 12 months after surgery. RESULTS Patients were stratified into three groups by preoperative estimated glomerular filtration rate level: 144 (43.9%) with estimated glomerular filtration rate ≥90, 130 (39.6%) with estimated glomerular filtration rate within 60-89.9, and 54 (16.5%) with estimated glomerular filtration rate <60 mL/min/1.73 m2 . The estimated glomerular filtration rate decreased significantly at the 6th month and remained stable at the 12th month, postoperatively. Patients with estimated glomerular filtration rate ≥90 had better clinical outcome with 59.6% success rate (P = 0.006) among three groups. Multivariate logistic regression analysis indicated that preoperative estimated glomerular filtration rate (odds ratio 1.012, P = 0.02) and hypokalemia (odds ratio 2.018, P = 0.024) were associated with renal impairment at 12th month after adrenalectomy. Multivariate linear regression analysis revealed high preoperative estimated glomerular filtration rate (β = 0.261, P < 0.001), high preoperative systolic blood pressure (β = 0.168, P = 0.003), high level of microalbuminuria (β = 0.024, P = 0.001), and low level of serum potassium (β = -4.883, P = 0.007) were associated with estimated glomerular filtration rate percentage decline at 12th month after adrenalectomy. CONCLUSIONS Estimated glomerular filtration rate declined significantly after adrenalectomy in patients with estimated glomerular filtration rate ≥90. The study provided important information to identify primary aldosteronism patients with higher risk of estimated glomerular filtration rate decline after adrenalectomy and might help to adopt early interventions to improve the outcomes.

GRAde: a long-read sequencing approach to efficiently identifying the CYP11B1/CYP11B2 chimeric form in patients with glucocorticoid-remediable aldosteronism. BMC Bioinformatics 2022; 22:613. [PMID: 35012455 PMCID: PMC8750845 DOI: 10.1186/s12859-022-04561-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Accepted: 01/03/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Glucocorticoid-remediable aldosteronism (GRA) is a form of heritable hypertension caused by a chimeric fusion resulting from unequal crossing over between 11β-hydroxylase (CYP11B1) and aldosterone synthase (CYP11B2), which are two genes with similar sequences. Different crossover patterns of the CYP11B1 and CYP11B2 chimeric genes may be associated with a variety of clinical presentations. It is therefore necessary to develop an efficient approach for identifying the differences between the hybrid genes of a patient with GRA. RESULTS We developed a long-read analysis pipeline named GRAde (GRA deciphering), which utilizes the nonidentical bases in the CYP11B1 and CYP11B2 genomic sequences to identify and visualize the chimeric form. We sequenced the polymerase chain reaction (PCR) products of the CYP11B1/CYP11B2 chimeric gene from 36 patients with GRA using the Nanopore MinION device and analyzed the sequences using GRAde. Crossover events were identified for 30 out of the 36 samples. The crossover sites appeared in the region exhibiting high sequence similarity between CYP11B1 and CYP11B2, and 53.3% of the cases were identified as having a gene conversion in intron 2. More importantly, there were six cases for whom the PCR products indicated a chimeric gene, but the GRAde results revealed no crossover pattern. The crossover regions were further verified by Sanger sequencing analysis. CONCLUSIONS PCR-based target enrichment followed by long-read sequencing is an efficient and precise approach to dissecting complex genomic regions, such as those involved in GRA mutations, which could be directly applied to clinical diagnosis. The scripts of GRAde are available at https://github.com/hsu-binfo/GRAde .

Characteristics of a Novel ATP2B3 K416_F418delinsN Mutation in a Classical Aldosterone-Producing Adenoma. Cancers (Basel) 2021; 13:cancers13184729. [PMID: 34572956 PMCID: PMC8472399 DOI: 10.3390/cancers13184729] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Revised: 09/14/2021] [Accepted: 09/15/2021] [Indexed: 11/17/2022] Open
Abstract
Simple Summary The ATP2B3 channel mutation is a rare cause of primary aldosteronism (PA). ATP2B3 gene mutation leads to the dysfunction of calcium channel that pumps calcium ion out of the cell and accumulates intracellular calcium signal to stimulate aldosterone synthesis. In the present study, we found a novel somatic ATP2B3 K416_F418delinsN mutation in a PA patient, and proved its functionality by demonstrating aldosterone hyper-function in the mutant-transfected adrenal cell-line. The ATP2B3 K416_F418delinsN mutation resulted from the deletion from nucleotides 1248 to 1253. The translated amino acid sequence from 416 to 418 as lysine-phenylalanine-phenylalanine was deleted and an asparagine was inserted due to the merging of residual nucleotide sequences. Abstract In patients with primary aldosteronism (PA), the prevalence of ATP2B3 mutation is rare. The aim of this study is to report a novel ATP2B3 mutation in a PA patient. Based on our tissue bank of aldosterone-producing adenomas (APA), we identified a novel somatic ATP2B3 K416_F418delinsN mutation. The affected individual was a 53 year-old man with a 4 year history of hypertension. Computed tomography (CT) showed bilateral adrenal masses of 1.6 (left) and 0.5 cm (right) in size. An adrenal venous sampling (AVS) showed a lateralization index (LI) of 2.2 and a contralateral suppression index (CLS) of 0.12; indicating left functional predominance. After a left unilateral adrenalectomy, he achieved partial biochemical and hypertension–remission. This classical adenoma harbored a novel ATP2B3 K416_F418delinsN somatic mutation, which is a deletion from nucleotides 1248 to 1253. The translated amino acid sequence from 416 to 418, reading as lysine-phenylalanine-phenylalanine, was deleted; however, an asparagine was inserted due to merging of residual nucleotide sequences. The CYP11B2 immunohistochemistry staining demonstrated strong immunoreactivity in this classical adenoma. The ATP2B3 K416_F418delinsN mutation is a functional mutation in APA, since HAC15 cells, a human adrenal cell line, transfected with the mutant gene showed increased CYP11B2 expression and aldosterone production.

Comparison of cystatin C-based and creatinine-based glomerular filtration rate in the prediction of postoperative residual hypertension in aldosterone-producing adenoma patients after adrenalectomy. Clin Chim Acta 2021; 520:147-153. [PMID: 34116005 DOI: 10.1016/j.cca.2021.06.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2020] [Revised: 04/12/2021] [Accepted: 06/03/2021] [Indexed: 12/14/2022]
Abstract
Renal function is associated with postoperative residual hypertension in aldosterone-producing adenoma(APA) patients. Cystatin C-based glomerular filtration rate (GFR) can more accurately estimate renal function than creatinine-based methods. However, which renal function estimation method can more accurately predict postoperative hypertension in APA patients is still unknown. We recruited 180 APA patients who underwent adrenalectomy. Preoperative creatinine and cystatin C-based GFRs were calculated. Residual hypertension was defined as persistent hypertension > 140/90 mmHg or requiring anti-hypertensive medications 1 year after surgery. Sixty-five(36.1%) of the 180 APA patients had residual hypertension. Multivariate logistic regression and receiver operating characteristic (ROC) curve analysis showed a combination of creatinine and cystatin method CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) creatinine-cystatin GFR was significantly associated with residual postoperative hypertension and had the largest area under the ROC curve, which was statistically larger than that of Cockcroft-Gault creatinine-based GFR. In both net reclassification index and integrated discrimination index models, CKD-EPI creatinine-cystatin GFR significantly improved the discriminatory power of CG-GFR. Among these renal function estimations used in the presented study, creatinine-cystatin combined GFR was a precise method to predict residual postoperative hypertension in APA patients received adrenalectomy. These finding may help identify those patients with higher risk of residual hypertension after operation.

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.

Evaluation of Abdominal Computed Tomography Scans for Differentiating the Discrepancies in Abdominal Adipose Tissue Between Two Major Subtypes of Primary Aldosteronism. Front Endocrinol (Lausanne) 2021; 12:647184.

Abstract
The aim of this study was to analyze the differences in the distribution of abdominal adipose tissue between the two subtypes of primary aldosteronism (PA) using abdominal computed tomography. We retrospectively analyzed patients diagnosed as having essential hypertension (EH) or PA from the prospectively collected Taiwan Primary Aldosteronism Investigation (TAIPAI) database. Patients with PA were divided into the subgroups of idiopathic hyperaldosteronism (IHA) and unilateral aldosterone-producing adenoma (APA). Patients' basic clinicodemographic data were collected, and a self-developed CT-based software program was used to quantify the abdominal adiposity indexes, including visceral adipose tissue (VAT) area, VAT ratio, waist circumference (WC), subcutaneous adipose tissue (SAT) area, and SAT ratio. We included 190 patients with EH and 436 patients with PA (238 with IHA and 198 with APA). The APA group had significantly lower abdominal adiposity indexes than the other groups. We also found negative correlations of aldosterone-to-renin ratio (ARR) with VAT area, VAT ratio, WC, and body mass index (BMI) in the APA group. After propensity score matching (which left 184 patients each in the IHA and APA groups), patients in the APA group still had significantly lower WC, SAT area, SAT ratio, and VAT ratio than those in the IHA group. Furthermore, logistic regression analysis indicated that lower probability of abdominal obesity was significantly related to patients with APA. Our data revealed that the distribution of abdominal adipose tissue was similar in patients with IHA and those with EH, but the abdominal adiposity indexes were significantly lower in patients with APA than in those with IHA and EH.

Abstract
CONTEXT The association between arterial stiffness and clinical outcome in lateralized primary aldosteronism (PA) patients after adrenalectomy has not been clearly identified. OBJECTIVE We hypothesized that arterial stiffness estimated by brachial-ankle pulse wave velocity (baPWV) before adrenalectomy was associated with the clinical outcomes and cardiorenal injury in lateralized PA patients after adrenalectomy. DESIGN AND PATIENTS We designed a retrospective observational cohort study. We collected lateralized PA patients who had undergone adrenalectomy between 2013 and 2016 from the Taiwan Primary Aldosteronism Investigation database. The primary outcome was achieving complete clinical success at 1 year after adrenalectomy. The secondary outcome was estimated glomerular filtration rate declining over 20% and improved left ventricular mass index. RESULTS We enrolled 221 patients with lateralized PA (50.7% men; mean age, 51.9 years), of whom 101 patients (45.7%) achieved complete clinical success at the 1-year follow-up assessment after adrenalectomy. Lower baPWV before adrenalectomy (odds ratio = 0.998; 95% confidence interval, 0.996-0.999; P = 0.003) correlated with higher likelihood of complete clinical success by multivariate logistic regression analysis. Multifactorial adjusted generalized additive model demonstrated that preoperative baPWV<1600 cm/sec was significantly associated with complete cure of hypertension. In addition, higher preoperative baPWV was associated with renal function decline and less left ventricular mass regression after adrenalectomy in lateralized PA patients during the follow-up period. CONCLUSIONS Our study demonstrated that the preoperative severe arterial stiffness was associated with absent complete clinical success in lateralized PA patients after adrenalectomy, and this effect may contribute to cardiorenal injury, which at least partially explains kidney function deterioration and lessened regression of heart mass.

Abstract
INTRODUCTION Primary aldosteronism (PA) is a common form of secondary hypertension that has significant cardiovascular events and increased prevalence of metabolic syndrome and diabetics. Although plasma aldosterone concentration is positively correlated with visceral fat area (VFA) in non-PA individuals, the role of visceral adiposity associated with clinical success after surgery is not known. RESEARCH DESIGN AND METHODS We analyzed patients who underwent adrenalectomy for aldosterone-producing adenoma (APA) at the Taiwan PA Investigator group. VFA was calculated from the abdominal CT scan at APA diagnosis, and all patients received adrenalectomy. RESULTS The study involved 100 consecutive patients with APA (42 males; mean age 49.3 years) matched with 41 essential hypertension (EH) patients. Patients with APA had smaller VFA (p=0.010) than their EH counterparts. Multiple linear regression analysis revealed that the duration of hypertension (p=0.007), but not plasma aldosterone, was negatively correlated with VFA in patients with APA. Logistic regression analysis showed that log VFA (OR=0.065, p<0.001) and duration of hypertension before PA diagnosis (OR=0.919, p=0.011) can predict complete clinical success after adrenalectomy. Multifactor-adjusted generalized additive model demonstrated that log VFA <9.2 was associated with complete cure of hypertension. Furthermore, VFA was increased at 6 months after adrenalectomy (p=0.045). CONCLUSIONS Patients with APA had smaller VFA than their EH counterparts, and VFA increased after adrenalectomy. Clinical complete cure of hypertension after surgery was associated with smaller VFA and shorter duration of hypertension at PA diagnosis, suggesting a potential interplay of visceral adiposity and aldosterone of the patients with APA.

Abstract
BACKGROUND Primary aldosteronism is associated with a higher incidence of left ventricular (LV) hypertrophy and diastolic dysfunction than essential hypertension. However, systolic function via endocardial measurements is similar between patients with primary aldosteronism and essential hypertension. Speckle-tracking echocardiography is a sensitive tool which can detect subclinical impairments in systolic function. The aim of this study was to investigate aldosterone-induced subclinical impairments in systolic function. METHODS We prospectively enrolled patients with primary aldosteronism and essential hypertension and analyzed their clinical data, biochemical data, and echocardiographic parameters, including myocardial strain [global longitudinal strain (GLS)]. RESULTS Thirty-six patients with primary aldosteronism and 31 patients with essential hypertension were enrolled for analysis. The patients with primary aldosteronism had significantly lower serum potassium levels, lower plasma renin activity, higher aldosterone-to-renin ratio (ARR), and higher 24-h urinary aldosterone levels than patients with essential hypertension. With regards to echocardiographic parameters, the patients with primary aldosteronism had a thicker ventricular wall and higher LV mass index than those with essential hypertension. Most importantly, we found significant degradation of GLS in the patients with primary aldosteronism compared with those with essential hypertension (-17.84 ± 2.36 vs. -20.13 ± 2.32, P < 0.001). In correlation analysis, GLS was significantly correlated with serum potassium level, LV mass index, log-transformed plasma renin activity, log-transformed ARR, and log-transformed 24-h urinary aldosterone levels (all P < 0.05). Multivariate linear regression analysis further identified log-transformed ARR (β = 0.771, 95% confidence interval: 0.011-1.530, P = 0.047), and log-transformed 24-h urinary aldosterone level (β = 1.765, 95% confidence interval: 0.01-3.529, P = 0.050) as independent factors correlated with GLS. CONCLUSION Patients with primary aldosteronism have a lower magnitude of GLS than patients with essential hypertension, suggesting that aldosterone induces a subclinical decline in LV systolic function.

Systematic review of the clinical outcomes of mineralocorticoid receptor antagonist treatment versus adrenalectomy in patients with primary aldosteronism. Hypertens Res 2019; 42:817-824. [PMID: 30948836 DOI: 10.1038/s41440-019-0244-4] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2018] [Revised: 02/18/2019] [Accepted: 02/20/2019] [Indexed: 12/16/2022]
Abstract
Primary aldosteronism (PA) is the most common cause of secondary hypertension. The aim of this study was to review the clinical outcomes after mineralocorticoid receptor (MR) antagonist treatment versus adrenalectomy treatment in patients with PA. Relevant medical literature from PubMed, the Cochrane Library, and the ICHUSHI database from 1985 to August 2017 was reviewed. Data extraction was performed independently by three authors. The incidence of cerebrovascular or cardiovascular disease, the improvement of left ventricular hypertrophy or hypokalemia, the severity of hypertension, the incidence of renal dysfunction, and the reduction in the number of oral antihypertensive agents were set as the clinical outcomes. Of the 302 articles selected, 16 were included in the final analysis. Regarding the two therapeutic strategies, no difference in the reduced incidence of cerebrovascular or cardiovascular disease, the prevalence of left ventricular hypertrophy or hypokalemia, or the severity of hypertension, as well as an increase in the incidence of renal dysfunction was observed. Regarding the decrease in the number of oral antihypertensive agents, more agents were reduced in patients who underwent adrenalectomy. Available evidence indicated that the clinical outcomes were not different in PA patients treated with MR antagonist or adrenalectomy, except for a reduction in the number of antihypertensive agents.

Plasma Aldosterone Concentration as a Determinant for Statin Use among Middle-Aged Hypertensive Patients for Atherosclerotic Cardiovascular Disease. J Clin Med 2018; 7:jcm7110382. [PMID: 30355992 PMCID: PMC6262476 DOI: 10.3390/jcm7110382] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2018] [Revised: 10/15/2018] [Accepted: 10/15/2018] [Indexed: 01/19/2023] Open
Abstract
The use of statin therapy on the prevention of atherosclerotic cardiovascular disease (ASCVD) is recommended by the American College of Cardiology (ACC) and the American Heart Association (AHA); nevertheless, its validation on primary aldosteronism (PA) patients has not been reported. We investigated the risk of incident ASCVD in middle-aged patients with PA compared with essential hypertension (EH) based on ACC/AHA recommendations. We enrolled 461 PA patients and 553 EH patients. Even though the ratio of metabolic syndrome in each group was similar, the PA group had higher systolic blood pressures, higher low-density lipoprotein levels, higher plasma aldosterone concentration (PAC), lower high-density lipoprotein levels, and higher 10-year ASCVD compared to the EH group. The discriminative power for predicting ASCVD by the recommended statin use from the ACC/AHA guidelines was proper in the PA group (i.e., under the receiver operating characteristic curve (95% confidence interval; 0.94 (0.91–0.96)). The generalized additive model showed patients with PAC higher than 60 ng/dL accompanying the standard timing of the statin use suggested by the ACC/AHA. The ACC/AHA guidelines have good discriminative power in the prediction of middle-aged high-risk hypertensive patients, while PAC identifies those high-risk individuals who may benefit from early statin therapy.

Abstract
Objectives Adrenocortical scintigraphy for patients with primary aldosteronism (PA) without discontinuation or modification of antihypertensive medications is of concern because of drug interference with the renin-angiotensin-aldosterone system. We report the surgical outcomes of patients with PA lateralized with adrenocortical scintigraphy without drug discontinuation or modification. Materials and Methods We retrospectively reviewed 34 patients with PA with computed tomography (CT)-documented adrenal tumors who had undergoing subsequent I-131-6 β-iodomethyl-norcholesterol (NP-59) single photon emission CT (SPECT)/CT followed by unilateral adrenalectomy according to the results of NP-59 uptake between May 2005 and December 2014. All enrolled patients underwent standard confirmatory tests and lateralization with NP-59 SPECT/CT without discontinuation of existing antihypertensive medications, including spironolactone. The pathological findings, hypertension outcomes, and biochemical changes were reported. The accuracy of NP-59 SPECT/CT without drug discontinuation or modification was also evaluated. Results None of the 34 enrolled patients (M:F = 16:18) had complications such as a hypertensive crisis, life-threatening hypokalemic event, or cardiac arrhythmia. Pathology disclosed 31 (91%) adenomas and three cases of hyperplasia. Hypertension cure and improvement were observed in 12 (35%) and 18 (53%) patients, respectively. All of the 30 patients (100%) without postoperative use of beta-blockers and with an available postoperative aldosterone/renin ratio achieved a biochemical cure. The positive predictive values of NP-59 SPECT/CT were 91%, 88%, and 100% for the pathological findings, hypertension outcomes, and biochemical changes, respectively. Conclusion Noninvasive NP-59 SPECT/CT without discontinuation or modification of antihypertensive medications not only provided accurate lateralization and safety but also resulted in a high improvement rate for PA-associated hypertension.

Abstract
OBJECTIVE The current study aimed to evaluate the role of Küpers' score in predicting unilateral aldosteronism, and develop a modified score in Chinese patients with primary aldosteronism. METHODS The current retrospective study included 406 patients with primary aldosteronism who underwent successful adrenal venous sampling (AVS) and were divided into the unilateral (n = 211) and bilateral (n = 195) groups according to the AVS results. Normokalemia was noted in both the unilateral (n = 64) and bilateral groups (n = 84) when plasma and urinary aldosterone were measured. RESULTS We evaluated Küpers' prediction score, which had the best cutoff value at four points [area under the curve, 0.601 (95% confidence interval 0.551-0.650); specificity, 53%; sensitivity, 62%]. Then, we modified this score by using urinary aldosterone level quartiles, history of hypokalemia, and typical adenoma more than 10 mm on computed tomography (CT) [area under the curve, 0.745 (95% confidence interval 0.667-0.813)]; sensitivity, 45.3%; specificity, 90.5%). The best cutoff value to discriminate unilateral from bilateral disease was a score of 5. This modified prediction score only applied to patients who were normokalemic when urinary aldosterone was measured. A specificity of 100% was achieved at a score of 6 for patients aged 40 years or less, and 5 when the adrenal lesion was on the right side on CT imaging. CONCLUSION Küpers' prediction score is not suitable for our patients. Urinary aldosterone levels combined with a history of hypokalemia are useful to discriminate unilateral from bilateral aldosteronism in patients with typical adenoma on the right adrenal gland on CT or in patients 40 years old or less.

Abstract
BACKGROUND/PURPOSE Even though the increasing clinical recognition of primary aldosteronism (PA) as a public health issue, its heightened risk profiles and the availability of targeted surgical/medical treatment being more understood, consensus in its diagnosis and management based on medical evidence, while recognizing the constraints of our real-world clinical practice in Taiwan, has not been reached. METHODS The Taiwan Society of Aldosteronism (TSA) Task Force acknowledges the above-mentioned issues and reached this Taiwan PA consensus at its inaugural meeting, in order to provide updated information of internationally acceptable standards, and also to incorporate our local disease characteristics into the management of PA. RESULTS When there is suspicion of PA, a plasma aldosterone to renin ratio (ARR) should be obtained initially. Patients with abnormal ARR will undergo confirmatory laboratory and image tests. Subtype classification with adrenal venous sampling (AVS) or NP-59 nuclear imaging, if AVS not available, to lateralize PA is recommended when patients are considered for adrenalectomy. The strengths and weaknesses of the currently available identification methods are discussed, focusing especially on result interpretation. CONCLUSION With this consensus we hope to raise more awareness of PA among medical professionals and hypertensive patients in Taiwan, and to facilitate reconciliation of better detection, identification and treatment of patients with PA.

Abstract
Salt intake is highly associated with cardiac structure in patients with primary aldosteronism (PA). We investigated the association among dietary salt intake, aldosterone and left ventricular mass in patients with PA. We enrolled 158 patients with PA and 158 patients with essential hypertension. We measured 24-hour urinary sodium (UNa) and aldosterone (UAldo) level and echocardiography parameters. In patients with PA, the UAldo level was positively correlated with left ventricular mass index (LVMI; r=0.231, p=0.007). The UNa level was not linearly correlated with left ventricular structural parameters in patients with PA. To test if UNa has a non-linear relationship with LVMI among patients with PA, we categorized the participants according to the tertile of UNa (low, median, and high tertile). PA patients with medium tertile of UNa had significant lower LVMI than the other two groups (LVMI: 144.1 ± 42.9, 121.1 ± 33.4, and 136.7 ± 32.8 g/m2, from the lowest to the highest tertile of Una; analysis of variance p=0.006, post-hoc p <0.05). Multifactor analysis of variance confirmed this finding after adjustment for clinical parameters. Post-hoc analyses revealed that the high UNa tertile was associated with higher left ventricular end-diastolic volume compared with medium UNa tertile; while the low UNa tertile was associated with higher mean wall thickness compared with medium UNa tertile. The findings imply the reasons for increased LVMI may be different in patients with the highest and lowest UNa tertile. In conclusion, the medium tertile of 24-hour UNa is associated with lowest LVMI in patients with PA.

The prevalence of CTNNB1 mutations in primary aldosteronism and consequences for clinical outcomes. Sci Rep 2017; 7:39121.

Abstract
Constitutive activation of the Wnt pathway/β-catenin signaling may be important in aldosterone-producing adenoma (APA). However, significant gaps remain in our understanding of the prevalence and clinical outcomes after adrenalectomy in APA patients harboring CTNNB1 mutations. The molecular expression of CYP11B2 and gonadal receptors in adenomas were also explored. Adenomas from 219 APA patients (95 men; 44.2%; aged 50.5 ± 11.9 years) showed a high rate of somatic mutations (n = 128, 58.4%). The majority of them harbored KCNJ5 mutations (n = 116, 52.9%); 8 patients (3.7%, 6 women) had CTNNB1 mutations. Patients with APAs harboring CTNNB1 mutations were older and had shorter duration of hypertension. After adrenalectomy, CTNNB1 mutation carriers had a higher possibility (87.5%) of residual hypertension than other APA patients. APAs harboring CTNNB1 mutations have heterogeneous staining of β-catenin and variable expression of gonadal receptors and both CYP11B1 and CYP11B2. This suggests that CTNNB1 mutations may be more related to tumorigenesis rather than excessive aldosterone production.

Abstract
In this retrospective study, we aimed to examine the effect of applying Dyna computed tomography (CT) on the success rate of adrenal venous sampling (AVS) without adrenocorticotropic hormone stimulation. A total of 100 consecutive patients with primary aldosteronism who underwent AVS between May 2012 and July 2015 were enrolled. In all the cases, Dyna CT was used in AVS to validate catheter position in the right adrenal vein. A selectivity index (cortisoladrenal vein /cortisolinferior vena cava) of ≥2.0 of both adrenal veins were required for successful AVS. Dyna CT indicated misplaced catheters in 16 patients; of these patients, 75% (12/16) eventually had successful right AVS after catheter repositioning. The success rate of initial sampling at the right adrenal vein was 76% (76/100), which increased to 88% (88/100) after Dyna CT was applied (p < 0.001). The most common inadvertently catheterised vessels detected using Dyna CT were the accessory hepatic veins (56.3%, 9/16), followed by the renal capsular veins (37.5%, 6/16). The overall success rate of non-stimulated AVS using Dyna CT was 87% (87/100). Thus, the application of Dyna CT further increased the success rate of non-stimulated AVS.

Abstract
Primary aldosteronism (PA) is the most common cause of secondary hypertension and consists up to 11% of patients with hypertension. Adrenal venous sampling (AVS) is the recommended procedure for diagnosis of PA, but the technique is difficult and the right adrenal vein is especially hard to catheterize. We retrospectively examined the clinically relevant anatomy of the right adrenal vein in a sample of 66 PA patients with technically successful AVS and distinctly-opacified right adrenal veins in Dyna computed tomography (CT). In the majority of cases: the right adrenal veins were catheterized when the catheter tilted posterior and rightward (57/66, 86.4%), the transverse direction of the right adrenal vein from the inferior vena cava (IVC) was posterior and rightward (55/66, 83.3%), and the vertical direction of the right adrenal vein from the IVC was caudal (52/66, 78.8%). This study shows that Dyna CT is able to provide detailed anatomical information to the course and direction of the right adrenal vein.

Abstract
UNLABELLED Primary aldosteronism has been associated with myocardial fibrosis, and is the most common cause of secondary hypertension. We previously showed that aldosterone can induce the secretion of galectin-3. The aim of this study was to investigate the association between myocardial fibrosis and plasma galectin-3 level in patients with primary aldosteronism. We prospectively analyzed 11 patients with aldosterone-producing adenoma (APA) who received adrenalectomy from December 2006 to October 2008, and 17 patients with essential hypertension as controls. Levels of plasma galectin-3 were determined in both groups, and both groups underwent echocardiography with cyclic variations of integrated backscatter (CVIBS) to characterize tissue initially and 1 year after surgery in the APA group. Diastolic blood pressure, concentration of plasma aldosterone and aldosterone-renin ratio were significantly higher, and serum potassium level and plasma renin activity significantly lower in the APA group compared to the controls. In addition, left ventricular mass index was significantly higher and CVIBS significantly lower in the APA group (7.3±2.0 vs 9.2±1.7 dB, p=0.015). Furthermore, the concentration of plasma galectin-3 was significantly higher in the APA group (2.1±0.9 vs 1.1±0.6 ng/mL, p=0.005) compared to the controls. CVIBS was correlated to plasma galectin-3 level. In the APA group, CVIBS increased significantly (7.3±2.0 to 9.2±2.4 dB, p=0.032) and plasma galectin-3 decreased (2.1±0.9 to 1.2±0.6, p=0.049) 1 year postadrenalectomy. The patients with APA had increased myocardial fibrosis, and this was associated with a higher plasma galectin-3 level. Both increased myocardial fibrosis and plasma galectin-3 level recovered at least partially after adrenalectomy. TRIAL REGISTRATION NUMBER 200611031R; Results.

Time course and factors predicting arterial stiffness reversal in patients with aldosterone-producing adenoma after adrenalectomy: prospective study of 102 patients. Sci Rep 2016; 6:20862. [PMID: 26883298 PMCID: PMC4756682 DOI: 10.1038/srep20862] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2015] [Accepted: 01/08/2016] [Indexed: 12/03/2022] Open
Abstract
Primary aldosteronism not only results in hypertension but also stiffer arteries. The time course and factors predicting the reversal of arterial stiffness after treatment are unclear. We prospectively enrolled 102 patients with aldosterone-producing adenoma (APA) from March 2006 to January 2012. We measured the pulse wave velocity (PWV) between brachial-ankle (baPWV) and heart-ankle (haPWV) before, 6 and 12 months after their adrenalectomy. After treatment, the PWV decreased significantly during the first 6 months (both p < 0.001), but no further reduction in the following 6 months. The determinant factors for baseline baPWV were age, duration of hypertension, and baseline systolic blood pressure (SBP) in multivariate linear regression analysis, similar with baseline haPWV (determinants: age, duration of hypertension, baseline SBP and diastolic blood pressure (DBP)). In multivariate linear regression analysis, the decrease in DBP at 6 months (ΔDBP0-6mo) and baseline baPWV were significantly associated with the decrease in baPWV at 6 months (ΔbaPWV0-6mo). The associated factors of the change in haPWV at 6 months (ΔhaPWV0-6mo) were baseline haPWV, ΔDBP0-6mo and change in log-transformed plasma renin activity. Our result suggested that reversal of arterial stiffness in APA patients occurred early after adrenalectomy and determined by baseline vascular condition, hemodynamic factors, and humoral factors.

Abstract
BACKGROUND Primary aldosteronism (PA) is one of the major etiologies for secondary hypertension featuring more prominent left ventricular hypertrophy. The purpose of the study was to investigate the predictive factors of left ventricular mass index (LVMI) regression in patients with PA after adrenalectomy. METHODS We prospectively analyzed 30 patients with aldosterone-producing adenoma (APA) who received adrenalectomy from October 2006 to September 2008. Echocardiography was performed preoperation and 1 year after operation. RESULTS Thirty patients with aldosterone-producing adenoma undergoing adrenalectomy were enrolled. In a 1-year follow-up, LVMI decreased significantly by an average of 18.6%. Net LVMI decrease (ΔLVMI) was associated with preoperative LVMI, preoperative serum potassium level, baseline systolic blood pressure (SBP), baseline diastolic blood pressure, net SBP decrease (ΔSBP), net diastolic blood pressure decrease, preoperative/postoperative change of log-transformed plasma aldosterone concentration, preoperative/postoperative change of log-transformed plasma renin activity, and preoperative/postoperative change of serum potassium level (Δserum potassium level). In a multiple regression analysis, preoperative LVMI (β = -0.287, P = 0.049), ΔSBP (β = 0.518, P = 0.01), and Δserum potassium level (β = -20.471, P = 0.014) were significantly correlated with ΔLVMI. CONCLUSIONS The LVMI in patients with PA regressed significantly after adrenalectomy. Preoperative LVMI, ΔSBP, and Δserum potassium levels are independent factors associated with the degree of LVMI regression.

Abstract
Excess aldosterone secretion in patients with primary aldosteronism (PA) impairs their cardiovascular system. Heart rhythm complexity analysis, derived from heart rate variability (HRV), is a powerful tool to quantify the complex regulatory dynamics of human physiology. We prospectively analyzed 20 patients with aldosterone producing adenoma (APA) that underwent adrenalectomy and 25 patients with essential hypertension (EH). The heart rate data were analyzed by conventional HRV and heart rhythm complexity analysis including detrended fluctuation analysis (DFA) and multiscale entropy (MSE). We found APA patients had significantly decreased DFAα2 on DFA analysis and decreased area 1-5, area 6-15, and area 6-20 on MSE analysis (all p < 0.05). Area 1-5, area 6-15, area 6-20 in the MSE study correlated significantly with log-transformed renin activity and log-transformed aldosterone-renin ratio (all p < = 0.01). The conventional HRV parameters were comparable between PA and EH patients. After adrenalectomy, all the altered DFA and MSE parameters improved significantly (all p < 0.05). The conventional HRV parameters did not change. Our result suggested that heart rhythm complexity is impaired in APA patients and this is at least partially reversed by adrenalectomy.

Abstract
Primary aldosteronism (PA) is a common form of secondary hypertension and has significant cardiovascular consequences. Mutated channelopathy due to the activation of calcium channels has been recently described in aldosterone-producing adenoma (APA). The study involved 148 consecutive PA patients, (66 males; aged 56.3 ± 12.3years) who received adrenalectomy, and were collected from the Taiwan PA investigator (TAIPAI) group. A high rate of somatic mutation in APA was found (n=91, 61.5%); including mutations in KCNJ5 (n=88, 59.5%), ATP1A1 (n=2, 1.4%), and ATP2B3 (n=1, 0.7%); however, no mutations in CACNA1D were identified. Mutation-carriers were younger (<0.001), had lower Cyst C (p=0.042), pulse wave velocity (p=0.027), C-reactive protein (p=0.042) and a lower rate of proteinuria (p=0.031) than non-carriers. After multivariate adjustment, mutation carriers had lower serum CRP levels than non-carriers (p=0.031. Patients with mutation also had a greater chance of recovery from hypertension after operation (p=0.005). A high incidence of somatic mutations in APA was identified in the Taiwanese population. Mutation-carriers had lower CRP levels and a higher rate of cure of hypertension after adrenalectomy. This raises the possibility of using mutation screening as a tool in predicting long-term outcome after adrenalectomy.

Abstract
BACKGROUND Primary aldosteronism (PA) is the most common cause of secondary hypertension. The main aims of this paper were to review outcome after surgical versus medical treatment of PA and partial versus total adrenalectomy in patients with PA. METHODS Relevant medical literature from PubMed, the Cochrane Library and Embase OvidSP from 1985 to June 2014 was reviewed. RESULTS Of 2036 records, 43 articles were included in the final analysis. Twenty-one addressed surgical versus medical treatment of PA, four considered partial versus total adrenalectomy for unilateral PA, and 18 series reported on surgical outcomes. Owing to the heterogeneity of protocols and reported outcomes, only a qualitative analysis was performed. In six studies, surgical and medical treatment had comparable outcomes concerning blood pressure, whereas six showed better outcome after surgery. No differences were seen in cardiovascular complications, but surgery was associated with the use of fewer antihypertensive medications after surgery, improved quality of life, and (possibly) lower all-cause mortality compared with medical treatment. Randomized studies indicate a role for partial adrenalectomy in PA, but the high rate of multiple adenomas or adenoma combined with hyperplasia in localized disease is disconcerting. Surgery for unilateral dominant PA normalized BP in a mean of 42 (range 20-72) per cent and the biochemical profile in 96-100 per cent of patients. The mean complication rate in 1056 patients was 4·7 per cent. CONCLUSION Recommendations for treatment of PA are hampered by the lack of randomized trials, but support surgical resection of unilateral disease. Partial adrenalectomy may be an option in selected patients.

Abstract
Context Patients with primary aldosteronism are associated with increased myocardial fibrosis. Galectin-3 is one of the most important mediators between macrophage activation and myocardial fibrosis. Objective To investigate whether aldosterone induces galectin-3 secretion in vitro and in vivo. Methods and Results We investigated the possible molecular mechanism of aldosterone-induced galectin-3 secretion in macrophage cell lines (THP-1 and RAW 264.7 cells). Aldosterone induced galectin-3 secretion through mineralocorticoid receptors via the PI3K/Akt and NF-κB transcription signaling pathways. In addition, aldosterone-induced galectin-3 expression enhanced fibrosis-related factor expression in fibroblasts. We observed that galectin-3 mRNA from peripheral blood mononuclear cells and serum galectin-3 levels were both significantly increased in mice implanted with aldosterone pellets on days 7 and 14. We then conducted a prospective preliminary clinical study to investigate the association between aldosterone and galectin-3. Patients with aldosterone-producing adenoma had a significantly higher plasma galectin-3 level than patients with essential hypertension. One year after adrenalectomy, the plasma galectin-3 level had decreased significantly in the patients with aldosterone-producing adenoma. Conclusion This study demonstrated that aldosterone could induce galectin-3 secretion in vitro and in vivo.

Abstract
BACKGROUND High aldosterone concentrations are associated with the risk of stroke that is independent of blood pressure levels. We investigated the risk of ischemic stroke in primary aldosteronism (PA) patients. METHODS This retrospective case-control study was based on the Taiwan Primary Aldosteronism Investigation (TAIPAI) database from 2004 to 2010. The study group comprised the patients who developed ischemic stroke after the diagnosis of PA. The PA patients who did not develop stroke were matched according to age and sex as the control group. A multivariate logistic regression model was performed to determine the risk factors of ischemic stroke. RESULTS Of 339 patients diagnosed with PA, 22 patients (6.5%) developed de novo ischemic stroke. The PA patients with stroke suffered from a longer hypertensive period (11.0±6.5 vs 7.8±8.3, P=.007) and a higher prevalence of proteinuria than those who did not develop stroke (40.9% vs 12.9%, P=.002). A multivariate logistic regression model showed that PA patients with proteinuria (HR 3.58, P=.02), preexisting coronary artery disease (HR 11.12, P<.001) or left ventricular hypertrophy (HR 3.09, P=.047) were associated with an increased risk of ischemic stroke. CONCLUSIONS Proteinuria, a medical history of coronary artery disease or left ventricular hypertrophy, was associated with an increased risk of ischemic stroke in PA patients. Our results suggest that a public health initiative is necessary to enhance the follow-up of proteinuria and to manage subsequent stroke among patients with aldosteronism.

Abstract
OBJECTIVE The diagnosis of primary aldosteronism (PA) among the older-aged population has posed a crucial challenge. Among patients over 50 years old, this trial assessed comparability of the performance of two PA diagnostic tests: losartan and captopril suppression tests. METHODS A post-hoc subgroup analysis from a prospective cohort was conducted by the TAIPAI (Taiwan Primary Aldosteronism Investigation) group between July 2003 and July 2006. Of the 160 patients in the cohort, 60 patients over 50 years old received captopril and losartan tests to confirm PA. RESULTS Among the 60 patients over 50 years old, 31 patients had PA confirmed by standardized protocol. The area under the receiver-operating characteristic (ROC) curve for post-captopril aldosterone was significantly less than that for post-losartan plasma aldosterone concentration (PAC) (0.87 vs 0.94, p=0.02). Using the aldosterone-renin ratio (ARR)>35 with PAC>10 ng/dl, the specificity was 82.76% vs 93.1% and the sensitivity was 77.42% vs 87.10% for the captopril and losartan tests, respectively. The equivalence between the two tests were confirmed by the exact McNemar's test (p=1.0). CONCLUSION The losartan test showed comparable accuracy to confirm PA. Verification of this "elderly-friendly" confirmatory test will be the first step to prepare a specific diagnostic model of PA for the older-aged population.

Abstract
OBJECTIVES To develop algorithms of locating patients with primary aldosteronism (PA) using insurance reimbursement data and to validate the algorithms using medical charts. STUDY DESIGN AND SETTING We extracted National Health Insurance (NHI) reimbursement data and medical charts in seven enrolled hospitals and analyzed diagnosis-related information for 1999-2010. The NHI codes PA as 255.1x, using the International Classification of Diseases, Ninth Revision, Clinical Modification. Confirmation of PA was based on suppression tests. RESULTS We reviewed medical charts for 1,094 cases with at least one PA diagnosis. PA was confirmed for 563 cases. Compared with patients with essential hypertension, PA patients had higher systolic blood pressure, higher aldosterone, lower renin activity, and lower potassium level (all P-values <0.05). An algorithm based on PA diagnosis reported in at least one hospital stay or three outpatient visits had modest performance (sensitivity = 0.94 and specificity = 0.20). The best additional condition for the algorithm was use of mineralocorticoid receptor antagonist (MRA; sensitivity = 0.89 and specificity = 0.88). CONCLUSION Using information on PA diagnosis and MRA prescription reported in insurance claims data can precisely locate PA patients in high-risk groups. This algorithm can construct a reliable PA sample for conducting research in various fields, including epidemiology and clinical practice.

Abstract
PURPOSE Primary aldosteronism (PA), characterized by an excessive production of aldosterone, affects 5-13 % of patients with hypertension. Accurate strategies are needed for the timely diagnosis of PA to allow curability and prevention of excessive cardiovascular events and related damage. This study aimed to evaluate the usefulness of semiquantification of (131)I-6β-iodomethyl-norcholesterol (NP-59) single photon emission computed tomography (SPECT)/CT in differentiating aldosterone-producing adenoma (APA) from idiopathic adrenal hyperplasia (IAH) and in predicting clinical outcomes after adrenalectomy. METHODS We retrospectively reviewed 49 PA patients who had undergone adrenalectomy after NP-59 SPECT/CT within 1 year. A conventional visual scale (VS) and two semiquantitative parameters generated from SPECT/CT, adrenal to liver ratio (ALR) and lesion to contralateral ratio of bilateral adrenal glands (CON), with cutoff values calculated by receiver-operating characteristic (ROC) analysis, were compared with pathology results and postsurgical outcomes to determine the accuracy. RESULTS An ALR cutoff of 1.84 and a CON cutoff of 1.15 showed an ability to distinguish adenoma from hyperplasia similar to VS (p = 0.2592 and 0.1908, respectively). An ALR cutoff of 2.28 and a CON cutoff of 1.11 yielded the highest sensitivity and specificity to predict postsurgical outcomes, and an ALR of 2.28 had an ability superior to VS (p = 0.0215), while a CON of 1.11 did not (p = 0.1015). Patients with either ALR or CON greater than the cutoff had a high probability of positive postsurgical outcomes (n = 36/38), while patients with both ALR and CON less than the cutoff had a low probability of positive postsurgical outcomes (n = 2/11). CONCLUSION Semiquantification of NP-59 scintigraphy has an ability similar to VS in differentiating APA from IAH, but an excellent ability to predict postsurgical outcomes of adrenalectomy. An ALR or CON greater than the cutoff strongly suggests benefits from adrenalectomy, and both ALR and CON less than the cutoff implies a reduced chance of improvement in postsurgical outcome.

Abstract
OBJECTIVE In mice, a lack of cryptochrome results in up-regulation of aldosterone production due to high expression of the 3β-hydroxysteroid dehydrogenases (HSD3β) gene. The HSD3β pathway might play a pivotal role in aldosterone synthesis. This study aimed to determine the association of HSD3β and HSD3β2 gene variations with primary aldosteronism in a Taiwanese population. METHOD In this case-control cohort, 688 consecutive ethnically matched unrelated individuals including 362 primary aldosteronism and 326 essential hypertension cases were recruited. Nineteen tag single-nucleotide polymorphisms (SNPs) across HSD3β1, HSD3β2, and CYP11β2 were genotyped. Expression of HSD3β mRNA and immunohistochemical stain of HSD3β in the specimens of aldosterone-producing adenoma (APA) was compared with that in nonfunctional incidentaloma. RESULTS The SNPs of rs12410453 A allele in HSD3β2 gene [odds ratio (OR) 1.92, 95% confidence interval (CI) 1.13-3.32, P=0.018] and rs6203 C allele in the HSD3β1 gene (OR 2.21, 95% CI 1.28-3.95, P=0.006) showed significant association with primary aldosteronism, with corresponding population attributable risk of 6.7 and 30.7%, respectively. Primary aldosteronism patients of non-CC in rs6203 and non-GA in rs12401453 had lower plasma aldosterone-to-renin ratio. A haplotype in a linkage disequilibrium block containing rs6203 associated significantly with serum potassium level (OR 1.24, 95% CI 1.02-1.24, P=0.026). The expressions of HSD3β1 mRNA, HSD3β2 mRNA and HSD3β protein were increased in APA, as compared to incidentaloma. CONCLUSION Risk-conferring genetic variations in the HSD3β gene influenced susceptibility of primary aldosteronism. Concomitant presence of rs6203 CC and rs12410453 GA genotypes synergistically increased aldosterone-to-renin ratio.

Comparison of 24-h urinary aldosterone level and random urinary aldosterone-to-creatinine ratio in the diagnosis of primary aldosteronism. PLoS One 2013; 8:e67417. [PMID: 23840695 PMCID: PMC3696056 DOI: 10.1371/journal.pone.0067417] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2013] [Accepted: 05/18/2013] [Indexed: 12/22/2022] Open
Abstract
Background Historically, urinary aldosterone level measurement was a commonly employed confirmatory test to detect primary aldosteronism (PA). However, 24-h urine collection is inconvenient and cumbersome. We hypothesized that random urinary aldosterone measurements with correction for creatinine concentration might be comparable to 24-h urinary aldosterone levels (Uald-24 h) in the diagnosis of PA. Methods The non-concurrent prospective study was conducted between June 2006 and March 2008 in patients admitted for confirmation of aldosteronism by salt loading test. A 24-h urine sample, which was collected during hospitalization on the day before saline infusion testing after restoration of serum hypokalemia, was collected from all subjects. Moreover, participants were asked to collect a first bladder voiding random urine sample during clinic visits. Uald-24 h and the random urinary aldosterone-to-creatinine ratio (UACR) were calculated accordingly. Results A total of 102 PA patients (71 patients diagnosed of aldosterone-producing adenoma, 31 with idiopathic hyperaldosteronism) and 65 patients with EH were enrolled. The receiver operating characteristic curve showed comparable areas under the curves of UACR and Uald-24 h. The Bland-Altman plot showed mean bias but no obvious heteroscedasticity between the two tests. When using random UACR >3.0 ng/mg creatinine as the cutoff value, we obtained a specificity of 90.6% to confirm PA from essential hypertension. Conclusions Our study reinforce that the diagnostic accuracy of random UACR was comparable to that of Uald-24 h in PA patients. With the quickness and simplicity of the UACR method and its equivalence to Uald-24 h, this assay could be a good alternative diagnostic tool for PA confirmation.

Abstract
Primary aldosteronism (PA) is the most common secondary form of arterial hypertension, with a particularly high prevalence among patients with resistant hypertension. Aldosterone has been found to be associated with cardiovascular toxicity. Prolonged aldosteronism leads to higher incidence of cardiac events, glomerular hyperfiltration, and potentially bone/metabolic sequels. The wider application of aldosterone/renin ratio as screening test has substantially contributed to increasing diagnosis of PA. Diagnosis of PA consists of two phases: screening and confirmatory testing. Adrenal imaging is often inaccurate for differentiation between an adenoma and hyperplasia, and adrenal venous sampling is essential for selecting the appropriate treatment modality. The etiologies of PA have two main subtypes: unilateral (aldosterone-producing adenoma) and bilateral (micro- or macronodular hyperplasia). Aldosterone-producing adenoma is typically managed with unilateral adrenalectomy, while bilateral adrenal hyperplasia is amenable to pharmacological approaches using mineralocorticoid antagonists. Short-term treatment outcome following surgery is determined by factors such as preoperative blood pressure level and hypertension duration, but evidence regarding long-term treatment outcome is still lacking. However, directed treatments comprising of unilateral adrenalectomy or mineralocorticoid antagonists still potentially reduce the toxicities of aldosterone. Utilizing a physician-centered approach, we intend to provide up-dated information on the etiology, diagnosis, and the management of PA.

Abstract
OBJECTIVE The objective of this article is to measure serum dehydroepiandrosterone sulfate (DHEA-S) concentration in both genders with primary aldosteronism (PA). MATERIALS AND METHODS The study enrolled 78 subjects with normal controls, 46 subjects with essential hypertension and 85 subjects with PA from October 2007 to June 2011. Subjects with PA were divided into three subtype groups: aldosterone-producing adenoma (APA), bilateral idiopathic hyperplasia (IHA) and PA with negative imaging findings. RESULTS Women with PA (n = 49) had lower serum DHEA-S levels compared with normal controls and subjects with essential hypertension (p < 0.01). In subtype analysis, only female APAs had lower serum DHEA-S levels (p < 0.01 compared with normal controls, p < 0.01 compared with subjects with essential hypertension). In APA, a significant correlation between tumor size and serum DHEA-S was found in women (p < 0.01). CONCLUSION Our data suggested that serum DHEA-S levels are lower in women with PA. In subtype groups, only women with APA had lower serum DHEA-S. There was no significant difference between subjects with bilateral essential hyperplasia, PA with negative imaging findings, normal controls and subjects with essential hypertension in both genders. The serum DHEA-S level is negatively correlated with the size of APA.

Abstract
OBJECTIVE Primary aldosteronism is the most frequent cause of secondary hypertension and is associated with more prominent left ventricular hypertrophy and increased myocardial fibrosis. However, the reversibility of cardiac fibrosis is still unclear. Our objective was to investigate myocardial fibrosis in primary aldosteronism patients and its change after surgery. METHOD We prospectively analyzed 20 patients with aldosterone-producing adenoma (APA) who received adrenalectomy from December 2006 to October 2008 and 20 patients with essential hypertension were enrolled as the control group. Plasma carboxy-terminal propeptide of procollagen type I (PICP) determination and echocardiography including ultrasonic tissue characterization by cyclic variation of integrated backscatter (CVIBS) were performed in both groups and 1 year after operation in the APA group. RESULTS APA patients had significantly higher SBP and DBP, higher plasma aldosterone concentration (PAC), higher aldosterone-renin ratio (ARR), lower serum potassium levels, and lower plasma renin activity (PRA) than patients with essential hypertension. In echocardiography, APA patients had a higher left ventricular mass index than essential hypertension patients. APA patients had significantly lower CVIBS (6.2 ± 1.5 vs. 8.7 ± 2.0 dB, P < 0.001) and higher plasma PICP levels (107 ± 27 vs. 85 ± 24 μg/l, P = 0.009) than essential hypertension patients. In the correlation study, CVIBS is correlated with log-transformed PRA and log-transformed ARR and PICP is correlated with log-transformed PRA, log-transformed PAC, and log-transformed ARR. One year after adrenalectomy, CVIBS increased significantly (6.2 ± 1.5 to 7.3 ± 1.7 dB, P = 0.033) and plasma PICP levels decreased (107 ± 27 vs. 84 ± 28 μg/l, P = 0.026). CONCLUSION Increases in collagen content in the myocardium of APA patients may be reversed by adrenalectomy.

Abstract
Hypertension is a frequent early manifestation of autosomal dominant polycystic kidney disease (ADPKD). Several mechanisms can cause hypertension in ADPKD patients, although, primary aldosteronism (PA) as a possible manifestation of hypertension in ADPKD is extremely rare. We retrospectively reviewed the Taiwan Primary Aldosteronism Investigation (TAIPAI) database, which listed a total of 346 patients diagnosed with PA. Of these 346 patients, only three cases of concurrent PA and ADPKD were identified. These patients presented with hypertensive crisis and hypokalemia, and subsequent testing revealed aldosterone-producing adenomas (APAs) that were removed by laparoscopic adrenalectomy. Postoperatively, aldosterone-renin ratios (ARRs) and potassium levels normalized, and blood pressure improved. The diagnosis of PA in ADPKD is extremely challenging because multiple renal cysts can obscure the identification of adrenal adenomas, and ADPKD is associated with hypertension in almost all cases.(1) Because of frequent delays in the diagnosis of PA in ADPKD patients, future prospective studies to screen PA in hypertensive ADPKD patients may be necessary to evaluate the exact prevalence of coexistence of PA and ADPKD.
