Abstract
OBJECTIVE Adrenal venous sampling (AVS) is recommended for identifying the subtype of primary aldosteronism before making a surgical treatment decision, but failed cannulation of one adrenal vein is common. To evaluate whether using results of one adrenal vein during AVS could accurately predict unilateral primary aldosteronism. METHODS A retrospective study was conducted in primary aldosteronism patients receiving bilaterally or unilaterally successful AVS. The aldosterone-cortisol ratio from the adrenal vein divided by the aldosterone-cortisol ratio from the inferior vena cava (IVC) was calculated as the AV/IVC index. RESULTS The study examined 455 patients with primary aldosteronism, including 347 patients with unilateral primary aldosteronism. Among them, 250 and 125 patients received non- adrenocorticotropic hormone (ACTH) and ACTH-stimulated AVS, respectively, and 80 patients received both forms of AVS. Under non-ACTH-stimulated AVS, AUC of the AV/IVC index to diagnose ipsilateral and contralateral primary aldosteronism were 0.778 and 0.924, respectively. The specificity was 100% for both, with sensitivities of 5 and 26%, respectively, when using cutoffs of 17.05 to diagnose ipsilateral primary aldosteronism and 0.15 to diagnose contralateral primary aldosteronism. When using cutoffs of 3.60 and 0.70, the specificity decreased, but if combined with CT results (ipsilateral or contralateral adrenal nodules larger than 10 mm), the specificity could be maintained at 99%, with sensitivities of 33 and 45%, respectively. Under ACTH-stimulated AVS, the AV/IVC index showed similar accuracy to diagnose ipsilateral and contralateral primary aldosteronism. CONCLUSION The unilateral AV/IVC index can be used to diagnose unilateral primary aldosteronism during AVS. Combining CT results can increase the accuracy further.

Intraprocedural Cortisol Measurement Increases Adrenal Vein Cannulation Success Rate in Primary Aldosteronism: A Systematic Review and Meta-analysis. Am J Hypertens 2024; 37:134-142. [PMID: 37777871 DOI: 10.1093/ajh/hpad089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 09/09/2023] [Accepted: 09/14/2023] [Indexed: 10/02/2023] Open
Abstract
BACKGROUND This study aimed to explore the effectiveness of intraprocedural cortisol measurement (IPCM) for the technical success rates of bilateral adrenal vein, right adrenal vein (RAV), and left adrenal vein (LAV) cannulation during adrenal vein sampling (AVS). METHODS Systematic searches of PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were performed from database inception to May 10, 2023, without any restrictions. We estimated the overall effect estimates of outcomes using the Mantel-Haenszel random-effects model. We conducted subgroup analyses, meta-regression, and sensitivity analysis to explore the possible sources of between-study heterogeneity. RESULTS In total, 3,485 patients from 11 studies (three prospective and eight retrospective) were enrolled. Bilateral selectivity in patients who underwent IPCM during AVS was significantly higher than that in patients who underwent a routine AVS procedure (84% vs. 64%, RR 1.42, 95% confidence interval [CI]: 1.27-1.59, P < 0.01), with significant heterogeneity (I2 = 68%). A 42% relative risk reduction in the failure rate of bilateral adrenal vein cannulation was found in the IPCM group. Moreover, pooled analysis showed a significant increase in the success rates of RAV cannulation (84% vs. 72%, RR 1.21, 95% CI 1.12-1.31, P < 0.01, I2 = 33%) and LAV cannulation (89% vs. 84%, RR 1.05, 95% CI 1.02-1.08, P < 0.01, I2 = 4%) when IPCM was implemented during the AVS procedure compared to the routine AVS procedure. CONCLUSIONS An IPCM-based strategy during AVS appears to have a significant beneficial effect on improving the success rate of bilateral cannulation, RAV cannulation and LAV cannulation.

Corticotropin Stimulation in Adrenal Venous Sampling for Patients With Primary Aldosteronism: The ADOPA Randomized Clinical Trial. JAMA Netw Open 2023; 6:e2338209. [PMID: 37870836 PMCID: PMC10594148 DOI: 10.1001/jamanetworkopen.2023.38209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Accepted: 09/05/2023] [Indexed: 10/24/2023] Open
Abstract
Importance Adrenal venous sampling (AVS) is usually recommended to distinguish between unilateral and bilateral primary aldosteronism (PA) before definitive surgical or medical treatment is offered. Whether a treatment decision based on AVS with or without corticotropin (ACTH) stimulation leads to different biochemical and clinical remission rates in patients with PA remains unclear. Objective To evaluate whether treatment decisions based on AVS with or without ACTH stimulation lead to different biochemical and clinical remission rates in patients with PA. Design, Setting, and Participants This randomized clinical trial (RCT) was conducted at a tertiary hospital in China from July 8, 2020, to February 20, 2023, among patients with PA aged 18 to 70 years. Patients were followed up for 12 months after the initiation of treatment. An intention-to-diagnose analysis was conducted. Interventions Patients were randomly assigned to undergo either ACTH-stimulated or non-ACTH-stimulated AVS. Main Outcomes and Measures The primary end point was the proportion of patients with complete biochemical remission after 12 months of follow-up. Secondary outcomes included the proportion of patients who achieved complete clinical remission after 12 months of follow-up, dosages of antihypertensive agents, rate of successful bilateral AVS, and adverse events. Results Of 228 patients with PA, 115 were randomized to the non-ACTH-stimulated group (median age, 50.0 years [IQR, 41.0-57.0 years]; 70 males [60.9%]) and 113 to the ACTH-stimulated group (median age, 50.0 years [IQR, 43.5-56.5 years]; 63 males [55.8%]). A total of 68 patients (59.1%) underwent adrenalectomy in the non-ACTH group and 65 (57.5%) in the ACTH group. There was no significant difference in the proportion of patients with complete biochemical remission who were managed on the basis of AVS with vs without ACTH stimulation (with: 56 of 113 [49.6%]; without: 59 of 115 [51.3%]; P = .79). There also was no significant difference in the proportion of patients who achieved complete clinical remission between the non-ACTH and ACTH groups (26 of 115 [22.6%] and 31 of 113 [27.4%], respectively; P = .40). The intensity of therapy with antihypertensives, successful catheterization of bilateral adrenal veins, and incidence of adverse events did not significantly differ between the non-ACTH and ACTH groups. Conclusions and Relevance In this RCT, treatment of PA on the basis of non-ACTH-stimulated or ACTH-stimulated AVS did not lead to significant differences in clinical outcomes for the patients. These results suggest that ACTH stimulation during AVS may not have clinical benefit, at least in the Chinese population. Trial Registration ClinicalTrials.gov Identifier: NCT04461535.

Abstract
Adrenal vein sampling (AVS) is recommended for subtyping primary aldosteronism (PA) to identify lateralized or bilateral sources of aldosterone excess, allowing for better decision-making in regard to medical or surgical management on a case-by-case basis. To date, no consensus exists on protocols to be used during AVS, especially concerning sampling techniques, the timing of sampling, and whether or not to use adrenocorticotropic hormone (ACTH) stimulation. Interpretation criteria for selectivity, lateralization, and contralateral suppression vary from one expert center to another, with some favoring strict cut-offs to others being more permissive. Clinical and biochemical post-operative outcomes can also be influenced by AVS criteria utilized to indicate surgical therapy.In this review, we reanalyze studies on AVS highlighting the recent pathological findings of frequent micronodular hyperplasia adjacent to a dominant aldosteronoma (APA) overlapping with bilateral idiopathic hyperaldosteronism (IHA) etiologies, as opposed to the less frequent unilateral single aldosteronoma. The variable expression of melanocortin type 2 receptors in the nodules and hyperplasia may explain the frequent discordance in lateralization ratios between unstimulated and ACTH- stimulated samples. We conclude that aldosterone values collected during simultaneous bilateral sampling, both at baseline and post-ACTH stimulation, are required to adequately evaluate selectivity, lateralization, and contralateral suppression during AVS, to better identify all patients with PA that can benefit from a surgical indication. Recommended cut-offs for each ratio are also presented.

Abstract
Purpose The current clinical discrimination of the dominant side of primary aldosteronism (PA) mainly relies on invasive adrenal venous sampling (AVS) examination. This study investigated the feasibility of dual-energy CT energy imaging parameters as a novel biomarker in identifying bilateral adrenal dominant lesions. Methods Fifty PA patients with bilateral lesions who underwent CT and AVS of the adrenal glands at Shaanxi Provincial People's Hospital from October 2019 to June 2021 were retrospectively analyzed. Forty-eight patients had successful bilateral blood collection and two failed right-sided blood collection due to venous variation. Forty patients who were classified based on AVS underwent unilateral adrenalectomy and pathological findings confirmed adenoma in all cases. Quantitative dual-energy CT parameters were measured for all adrenal lesions, and the differences in dual-energy CT energy spectrum imaging parameters between the dominant and nondominant adrenal lesions were compared. Results Among forty-eight PA patients with bilateral lesions, forty patients with preoperative AVS-determined lesions on the dominant side underwent unilateral adrenalectomy, and eight patients without the dominant side were treated with medication. The iodine concentration difference (ICD) in the arteriovenous phase was more significant in the 40 cases of primary aldosteronism with dominant adrenal lesions than in the nondominant adrenal lesions (1.18 ± 0.45 vs 0.41 ± 0.42). The NICAP was higher in the dominant adrenal lesions than in the non-dominant lesions (0.39 ± 0.39 vs 0.14 ± 0.05). The sensitivity and specificity of the diagnosis of the dominant adrenal lesion were 88.2% and 82.4% using the ICD of 0.68 as the threshold value. Conclusion Conventional CT has lower diagnostic value for dominant adrenal lesions, and CT-based energy imaging can be a new assessment method as a complement to AVS in identifying bilateral dominant adrenal lesions.

Abstract
Primary aldosteronism is a common cause of hypertension and is a risk factor for cardiovascular and renal morbidity and mortality, via mechanisms mediated by both hypertension and direct insults to target organs. Despite its high prevalence and associated complications, primary aldosteronism remains largely under-recognized, with less than 2% of people in at-risk populations ever tested. Fundamental progress made over the past decade has transformed our understanding of the pathogenesis of primary aldosteronism and of its clinical phenotypes. The dichotomous paradigm of primary aldosteronism diagnosis and subtyping is being redefined into a multidimensional spectrum of disease, which spans subclinical stages to florid primary aldosteronism, and from single-focal or multifocal to diffuse aldosterone-producing areas, which can affect one or both adrenal glands. This Review discusses how redefining the primary aldosteronism syndrome as a multidimensional spectrum will affect the approach to the diagnosis and subtyping of primary aldosteronism.

Abstract
OBJECTIVE Primary aldosteronism (PA) is a common form of secondary hypertension. Adrenal venous sampling (AVS) is the gold standard for subtyping PA. This study aimed to determine whether there is a difference between immunoassays and liquid chromatography-mass spectrometry (LC-MS/MS) methods for measuring cortisol levels that affect the judgement of AVS. DESIGN This was a retrospective study. PATIENTS Included 72 patients who were diagnosed with PA and had undergone AVS. MEASUREMENTS Patients were grouped according to whether they received adrenocorticotropic hormone (ACTH) stimulation during AVS, and the cortisol results were measured using immunoassay and LC-MS/MS. RESULTS There were 48 patients in the without ACTH stimulation group and 24 in the post-ACTH stimulation group during AVS (bilateral adrenal vein cannulation success rate, 56.25% vs. 83.33%). ACTH stimulation was beneficial for increasing the success rate of AVS (p < .001). Immunoassays were linearly correlated with LC-MS/MS when cortisol concentrations were <1750 nmol/L (r = .959, p < .001). When cortisol concentrations were >17,500 nmol/L, no correlation was found between the two methods (p = .093). The two methods were consistent for the detection of cortisol for evaluating the success of cannulation for AVS. Five percent of patients showed discordant lateralization of aldosterone production according to the cortisol LC-MS/MS and immunoassay results in the without ACTH group, and 15% showed discordant lateralization in the post-ACTH group. CONCLUSIONS The immunoassay method can be used to determine whether cannulation is successful. The final decision for lateralization may be more appropriate based on LC-MS/MS results.

"Double-Down" Adrenal Vein Sampling Results in Patients with Apparent Bilateral Aldosterone Suppression: Utility of Repeat Sampling including Super-Selective Sampling. J Vasc Interv Radiol 2021; 32:656-665. [PMID: 33781686 DOI: 10.1016/j.jvir.2020.12.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Revised: 12/06/2020] [Accepted: 12/22/2020] [Indexed: 10/21/2022] Open
Abstract
PURPOSE To report outcomes of patients undergoing adrenal vein sampling (AVS) for primary aldosteronism with results indicating apparent bilateral adrenal suppression (ABAS), in which the adrenal aldosterone-to-cortisol ratios are decreased bilaterally ("double-down") compared to the non-adrenal sample, and evaluate repeat AVS results. MATERIALS AND METHODS Between 2003 and 2020, 762 patients underwent AVS. Twenty patients (2.6%; male, 12; female, 8; age 50.3 ± 9.7 years) with ABAS on initial AVS were identified. Ten underwent repeat AVS. Super-selective AVS (SS-AVS) was employed in 6 of 10 repeat AVS (60%). Outcomes after AVS were analyzed. A lateralization index (LI) >4 was considered an indication for adrenalectomy. RESULTS Repeat AVS was diagnostic in 70% of patients (n = 7), with 6 of 7 lateralizing with LI >4 (median LI = 32.3; range 4.6-54.8) and 1 of 7 nearly lateralizing (LI = 3.5). All 7 patients underwent adrenalectomy. ABAS was redemonstrated in 3 patients (30%): 2 with unilateral adenomas on cross-sectional imaging underwent adrenalectomy despite ABAS results and 1 was lost to follow-up. Four of 6 patients (66%) who underwent SS-AVS were diagnosed with unilateral disease (median LI = 43.3; range 23.9-54.8), with one patient's diagnosis reliant upon a single super-selective sample. In total, 9 patients underwent adrenalectomy after repeat AVS, all of whom had improved blood pressure control postoperatively. Ten patients did not undergo repeat AVS: 6 were lost to follow-up, 3 underwent medical management, and 1 underwent adrenalectomy. CONCLUSIONS AVS should be repeated when "double-down" ABAS results are encountered. Super-selective sampling may provide worthwhile diagnostic data when employed during repeat AVS.

Abstract
Several studies over the past 3 decades document a higher prevalence of primary aldosteronism (PA) among hypertensive patients than generally presumed. PA exists as a spectrum from mild to severe aldosterone excess. Although a variety of PA subtypes exist, the 2 most common are aldosterone-producing adenomas (APAs) and bilateral hyperaldosteronism (BHA). The distinction is important, because APA-and other subtypes, with aldosterone production mostly from 1 adrenal-can be cured surgically, and BHA should be treated medically with mineralocorticoid-receptor antagonists (MRAs). The major shortcomings in the tailored management of patients with possible PA are the low rates of screening for case identification and the expensive and technically challenging imaging and interventional procedures required to distinguish APA from BHA, especially adrenal vein sampling (AVS). When AVS identifies an APA and allows the patient to be cured surgically, the procedure is of great value. In contrast, the patient with BHA is treated with MRA whether AVS is performed or not. Consequently, it is prudent to gauge how likely it is to benefit from imaging and AVS in each case prior to embarking on these studies. The explosion of information about PA in the past decade, including predictors of APA and of surgical benefit, are useful in limiting the evaluation for some patients with a positive PA screening test. This article will review our suggestions for approaching these patients in a pragmatic style, recognizing the limitations to even the best resources and facilities.

J Clin Med 2020; 9:jcm9051447. [PMID: 32413990 PMCID: PMC7291054 DOI: 10.3390/jcm9051447] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Revised: 05/07/2020] [Accepted: 05/11/2020] [Indexed: 11/16/2022] Open
Abstract
The aim of this study is to determine the accuracy of adrenal vein sampling (AVS) with and without adrenocorticotropic hormone (ACTH) stimulation to distinguish between unilateral and bilateral primary hyperaldosteronism (PA). Retrospective analysis of a prospective database from a referral center between 1984 and 2009, 76 patients had simultaneous cannulation of bilateral adrenal veins and AVS with and without ACTH stimulation. All patients had adrenalectomies. The selectivity index (SI, cut-off value ≥2) was used for confirmation of successful cannulation of the adrenal vein. The lateralization index (LI, cut-off value >2 and >4) was used for distinguishing between unilateral and bilateral PA. The SI ratio was higher with ACTH stimulation compared to without for the right adrenal vein (p = 0.027). The LI >2 ratio was higher with ACTH stimulation compared to without (p = 0.007). For the LI >4 ratio, there was no difference between with and without ACTH stimulation (p = 0.239). However, for a LI >4, 7 patients (9.2%) were not lateralized with ACTH stimulation, but they did lateralize without ACTH stimulation. AVS with ACTH stimulation is associated with a higher SI ratio compared to AVS without ACTH stimulation. However, when using LI >4 for AVS, samples without ACTH stimulation should also be included to detect a subset of patients with unilateral disease that are not detected with ACTH stimulation.

Abstract
In adrenal venous sampling (AVS) for patients with primary aldosteronism (PA), adrenocorticotropic hormone (ACTH) stimulation generally increased the success rate. The effect of ACTH stimulation on the left-right differences of laterality diagnosis in AVS remains unclear. A total of 167 patients with PA underwent successful AVS were examined. Patients with autonomous cortisol secretion were excluded. The proportion of dominant side in AVS was compared before and after ACTH stimulation. Unilateral disease on AVS was defined as a lateralization index of more than 4, both before and after ACTH stimulation. Before ACTH stimulation, unilateral disease was more frequently observed on the right side than the left side (right 33.5% vs. left 13.8%, p < 0.01). After ACTH stimulation, unilateral disease was more frequently observed on the left side than the right side, without statistical significance (left 15.6% vs. right 10.8%, p = 0.20). Among the 56 patients who had right unilateral disease before ACTH stimulation, 17 patients (30.0%) also had right unilateral disease after ACTH stimulation. The affected side of AVS was changed from right unilateral to bilateral after ACTH stimulation in 34 (60.7%) out of 56 patients. These patients had milder PA and CT scans showed no nodular lesions on the right side. In AVS, ACTH stimulation not only decreased unilateral results but also shifted to the dominant side. Overestimation should be carefully considered when the surgical indication for the right adrenal gland was decided based on AVS results without ACTH stimulation.

Abstract
Adrenal venous sampling is the gold standard test to identify surgically curable primary aldosteronism, but it is markedly underused in clinical practice being perceived as a technically challenging and invasive procedure and, moreover, as difficult to interpret. This review provides updated information on current indications to adrenal venous sampling and how to perform and interpret adrenal venous sampling.

Abstract
CONTEXT Cosyntropin [ACTH (1-24)] stimulation during adrenal vein (AV) sampling (AVS) enhances the confidence in the success of AV cannulation and circumvents intraprocedure hormonal fluctuations. Cosyntropin's effect on primary aldosteronism (PA) lateralization, however, is controversial. OBJECTIVES To define the major patterns of time-dependent lateralization, and their determinants, after cosyntropin stimulation during AVS. METHODS We retrospectively studied patients with PA who underwent AVS before, 10, and 20 minutes after cosyntropin stimulation between 2009 and 2018. Unilateral (U) or bilateral (B) PA was determined on the basis of a lateralization index (LI) value ≥4 or <4, respectively. Available adrenal tissue underwent aldosterone synthase-guided next-generation sequencing. RESULTS PA lateralization was concordant between basal and cosyntropin-stimulated AVS in 169 of 222 patients (76%; U/U, n = 110; B/B, n = 59) and discordant in 53 patients (24%; U/B, n = 32; B/U, n = 21). Peripheral and dominant AV aldosterone concentrations and LI were highest in U/U patients and progressively lower across intermediate and B/B groups. LI response to cosyntropin increased in 27% of patients, decreased in 33%, and remained stable in 40%. Baseline aldosterone concentrations predicted the LI pattern across time (P < 0.001). Mutation status was defined in 61 patients. Most patients with KCNJ5 mutations had descending LI, whereas those with ATP1A1 and ATP2B3 mutations had ascending LI after cosyntropin stimulation. CONCLUSION Patients with severe PA lateralized robustly regardless of cosyntropin use. Cosyntropin stimulation reveals intermediate PA subtypes; its impact on LI varies with baseline aldosterone concentrations and aldosterone-driver mutations.

Abstract
OBJECTIVES The aim of this study was to present up to date information concerning the diagnosis and treatment of primary aldosteronism (PA). PA is the most common cause of endocrine hypertension. It has been reported up to 24% of selective referred hypertensive patients. METHODS We did a search in Pub-Med and Google Scholar using the terms: PA, hyperaldosteronism, idiopathic adrenal hyperplasia, diagnosis of PA, mineralocorticoid receptor antagonists, adrenalectomy, and surgery. We also did cross-referencing search with the above terms. We had divided our study into five sections: Introduction, Diagnosis, Genetics, Treatment, and Conclusions. We present our results in a question and answer fashion in order to make reading more interesting. RESULTS PA should be searched in all high-risk populations. The gold standard for diagnosis PA is the plasma aldosterone/plasma renin ratio (ARR). If this test is positive, then we proceed with one of the four confirmatory tests. If positive, then we proceed with a localizing technique like adrenal vein sampling (AVS) and CT scan. If the lesion is unilateral, after proper preoperative preparation, we proceed, in adrenalectomy. If the lesion is bilateral or the patient refuses or is not fit for surgery, we treat them with mineralocorticoid receptor antagonists, usually spironolactone. CONCLUSIONS Primary aldosteronism is the most common and a treatable case of secondary hypertension. Only patients with unilateral adrenal diseases are eligible for surgery, while patients with bilateral and non-surgically correctable PA are usually treated by mineralocorticoid receptor antagonist (MRA). Thus, the distinction between unilateral and bilateral aldosterone hypersecretion is crucial.

Abstract
PURPOSE OF REVIEW Current guidelines recommend adrenal venous sampling (AVS) to identify the surgically curable causes of hyperaldosteronism. In contrast with this recommendation, AVS remains markedly underutilized in clinical practice, which leads to deny curative adrenalectomy, to many patients with primary aldosteronism. The purpose of this review is to challenge the views that AVS is a technically challenging, invasive and risky procedure, which moreover, is difficult to interpret. RECENT FINDINGS Several studies, including a large international survey on how AVS is being performed and used at major referral centres worldwide the AVIS-1 Study - and a randomized clinical trial comparing and AVS and a computed tomography based strategy, will be examined. SUMMARY The results of these studies have sound implications for clinical practice in that they allow to define what to do and what not to do for proper performance and interpretation of AVS and avoidance of the main concern, for example the risk of adrenal vein rupture.

Abstract
OBJECTIVE Correct subtyping of primary aldosteronism (PA) is essential for good surgical outcomes. Adrenal vein sampling (AVS) and/or computed tomography (CT) are used for PA subclassification. Clinical and/or biochemical improvement after surgery, however, is not always achieved in patients with presumed unilateral PA. We aimed to identify the pitfalls in PA subclassification leading to surgical treatment failures. PATIENTS AND DESIGN We retrospectively studied 208 patients who underwent adrenal vein sampling (AVS) for PA subclassification in a tertiary referral centre, between January 2009 and August 2016. Simultaneous bilateral AVS was performed before and after cosyntropin administration. We implemented immunohistochemistry for aldosterone synthase (CYP11B2) and 17α-hydroxylase/17,20 lyase (CYP17A1) in adrenal glands resected from patients without improvement of PA after surgical treatment and from those with limitations in AVS interpretation. RESULTS Of 55 patients who underwent adrenalectomy, three (5.5%) had no improvement of PA. All three patients underwent partial adrenalectomy to remove a CT-detected nodule present on the same side with AVS lateralization. Immunohistochemistry revealed a CYP11B2-negative nodule in both cases available. All patients who underwent total adrenalectomy based on AVS lateralization benefitted from surgery, including three patients with unilateral unsuccessful AVS and aldosterone suppression in the catheterized side vs inferior vena cava. CONCLUSIONS Radiographically identified adrenal nodules are not always a source of PA, even when ipsilateral with AVS lateralization. These data caution against reliance on imaging findings, either alone or in conjunction with AVS, to guide surgery for PA.

Subtyping of primary aldosteronism with adrenal vein sampling: Hormone- and side-specific effects of cosyntropin and metoclopramide. Surgery 2017; 163:789-795.

Abstract
BACKGROUND Cosyntropin and metoclopramide can affect the subtyping of primary aldosteronism when used with adrenal vein sampling by exerting hormone- and side-specific effects on cortisol and aldosterone secretion. We investigated how these stimuli affect the selectivity index, the relative aldosterone secretion index, and the lateralization index in consecutive primary aldosteronism patients submitted to adrenal vein sampling. METHODS We recruited 171 patients; of these, 149 underwent adrenal vein sampling before and after stimulation with cosyntropin (250 µg intravenous bolus, n= 53, 73% with an aldosterone-producing adenoma) or with metoclopramide (10 mg intravenous bolus, n= 96, 65% aldosterone-producing adenoma), and 32 with an aldosterone-producing adenoma were investigated for the relative gene expression of dopamine, melanocortin 2, and 5-hydroxytryptamine (serotonin) 4 receptor with microarrays. Cosyntropin increased the selectivity index similarly on both sides; metoclopramide did not. Cosyntropin decreased relative aldosterone secretion index on the aldosterone-producing adenoma side but not contralaterally. Metoclopramide did not affect the selectivity index, but increased the relative aldosterone secretion index similarly on both sides. Because of these changes, cosyntropin decreased the lateralization index, while metoclopramide did not affect it. The relative gene expression of melanocortin 2, albeit heterogeneous across tumors, was 35% less (P<.0001) in aldosterone-producing adenoma than in the normal adrenal cortex, while dopamine receptor D2 and 5-hydroxytryptamine (serotonin) 4 receptors did not differ between tissues. CONCLUSION Cosyntropin, while facilitating ascertainment of selectivity, lessens the lateralization, likely because of a blunted melanocortin 2 expression in aldosterone-producing adenoma. The similar expression of dopamine and 5-hydroxytryptamine (serotonin) 4 receptors in aldosterone-producing adenoma and the normal adrenal cortex can explain why metoclopramide increased the relative aldosterone secretion index on both sides and, therefore, failed to increase the lateralization index.

Abstract
The term "adrenal incidentaloma" is a radiological term. Adrenal incidentalomas are adrenal tumors discovered in an imaging study that has been obtained for indications exclusive to adrenal conditions (Udelsman 2001; Linos 2003; Bulow et al. 2006; Anagnostis et al. 2009). This definition excludes patients undergoing imaging testing as part of staging and work-up for cancer (Grumbach et al. 2003; Anagnostis et al. 2009). Papierska et al. (2013) have added the prerequisite that the size of a tumor must be "greater than 1cm in diameter", in order to be called incidentaloma. Although in the most cases these masses are non-hypersecreting and benign, they still represent an important clinical concern because of the risk of malignancy or hormone hyperfunction (Barzon et al. 2003). Th e adrenal tumors belong to the commonest incidental findings having been discovered (Kanagarajah et al. 2012).

Abstract
Primary aldosteronism (PA) is the most common form of secondary hypertension and is critical to identify because when caused by an aldosterone-producing adenoma (APA) or another unilateral form, it is potentially curable, and even when caused by bilateral disease, antihypertensives more specific to PA treatment can be employed (ie, aldosterone antagonists). Identification of unilateral forms is not generally accomplished with imaging because APAs may be small and elude detection, and coincidental identification of a non-functioning incidentaloma contralateral to an APA may lead to removal of an incorrect gland. For this reason, the method of choice for identifying unilateral forms of PA is selective adrenal venous sampling (AVS) followed by aldosterone and cortisol analysis on collected samples. This procedure is technically difficult from a radiological standpoint and, from the laboratory perspective, is fraught with opportunities for preanalytical, analytical and postanalytical error. We review the process of AVS collection, analysis and reporting. Suggestions are made for patient preparation, specimen labelling practices and nomenclature, analytical dilution protocols, which numerical results to report, and the necessary subsequent calculations. We also identify and explain frequent sources of confusion in the aldosterone and cortisol results and provide an example of tabular reporting to facilitate interpretation and communication between laboratorian, radiologist and clinician.

For identification of potentially surgically curable primary aldosteronism, guidelines recommend use of adrenal vein sampling (AVS) that requires selective catheterization of both adrenal veins as verified by using the cortisol-derived selectivity index. Unfortunately, bilaterally selective studies are not obtained under unstimulated conditions in a proportion of the cases ranging between 15% and 50% depending on the cutoff used. We therefore investigated whether 17-α-hydroxyprogesterone and androstenedione, which showed a higher step-up between adrenal vein and inferior vena cava blood than cortisol, can ascertain selectivity when cortisol failed to do so. We prospectively recruited 32 hypertensive patients with confirmed primary aldosteronism, who underwent bilaterally simultaneous sampling without cosyntropin stimulation and with the same predefined AVS protocol. All were consecutively selected because of a cortisol-based selectivity index <2.00 in at least one of the paired adrenal vein blood samples collected as per protocol. Results showed that the values of the selectivity index based on 17-α-hydroxyprogesterone and androstenedione were higher (P<0.01) on average by 1.6- and 12-fold, respectively, than those based on cortisol. With use of these steroids, we rescued 43% and 73% of the AVS, respectively, from being judged nonselective. Thus, in challenging patients with primary aldosteronism submitted to AVS use of 17-α-hydroxyprogesterone, and even more so of androstenedione, for ascertaining selectivity allows demonstration of correct catheter placement in a proportion of AVS studies better than cortisol. Thus, replacing cortisol measurement with these steroids, and particularly androstenedione, can improve the diagnostic yield of AVS.

Abstract
OBJECTIVE A stress reaction involving increased adrenal hormone release occurs when starting adrenal venous sampling (AVS). The purpose of the present study was to investigate the effect of single shot venography on adrenal hormone production during AVS. SUBJECTS AND METHODS This was a prospective self-controlled study. We enrolled 54 consecutive patients (21 men, 33 women; mean age 52 ± 11 years) with primary aldosteronism who underwent AVS from May 2014 to February 2015. Under non-stimulated conditions, blood samples were obtained from a common trunk of the left adrenal vein before and after single shot venography. The initial plasma aldosterone and cortisol concentration (PAC and PCC) were compared with those measured after venography for each patient. RESULTS PAC and PCC were slightly but significantly decreased between before and after venography (after log transformation 2.12 ± 0.73 vs 2.07 ± 0.72, P = 0.00066, 1.89 ± 0.52 vs 1.83 ± 0.53, P = 0.00031, respectively). CONCLUSIONS During non-stimulated left AVS, adrenal hormone secretion was slightly but significantly decreased after venography, similar to the normal time-related stress reaction. Venography did not increase the adrenal hormone secretion.

Abstract
CONTEXT In adrenal vein sampling (AVS) for patients with primary aldosteronism, the contralateral ratio of aldosterone/cortisol (A/C) between the nondominant adrenal vein and the inferior vena cava is one of the best criteria for determining lateralized aldosterone secretion. Despite successful cannulation in some patients, the A/C ratios in the adrenal veins are bilaterally lower than that in the inferior vena cava (bilateral aldosterone suppression; BAS). OBJECTIVES To investigate the prevalence of BAS in AVS and how to resolve this condition. DESIGN AND SETTING Retrospective study involving nine referral centres. PATIENTS Four hundred and ninety-one patients who were confirmed as having primary aldosteronism and had an AVS between January 2006 and December 2013. MEASUREMENTS The prevalence of BAS before and after ACTH stimulation was compared. In addition, we investigated other methods for overcoming BAS. RESULTS In 304 patients with successful AVS before ACTH stimulation, BAS was observed in 29 (9·5%). BAS was resolved after ACTH stimulation in 22 patients. In 276 patients with successful AVS both before and after ACTH stimulation, the frequency of BAS was significantly reduced after ACTH (8·7% vs 2·5%, P < 0·01). In a few patients, BAS was also resolved by adding a sampling point at the common trunk of the left adrenal vein and by an alternative drainage vein from the adrenal tumour. CONCLUSIONS BAS sometimes occurs in AVS without ACTH stimulation. ACTH stimulation significantly reduces BAS with a single AVS procedure.

Abstract
CONTEXT Adrenal vein sampling (AVS) is required to identify a lateralized or bilateral aldosterone source in primary aldosteronism. OBJECTIVES Our objectives were to compare basal and post-ACTH selectivity ratio (SR) and lateralization ratio (LR) and to determine the prevalence of basal contralateral suppression and its effect on surgical outcome. PATIENTS AND INTERVENTION Bilateral simultaneous adrenal vein samples were obtained before and after a 250-μg bolus of ACTH. Analyses were conducted on 171 technically successful AVS and on the subgroup of 66 operated patients with evaluable outcome data. RESULTS ACTH increased selectivity on both sides from 66.7% in basal samples (SR ≥ 2) to 91.8% poststimulation (SR ≥ 5). A discordance of lateralization between basal (LR ≥ 2) and post-ACTH (LR ≥ 4) values was observed in 28% of cases, which were mostly lateralized cases basally that became bilateral post-ACTH. Basal CL suppression is present in only 30% using absolute ratio of aldosterone between the opposite (nondominant) adrenal vein and the peripheral vein AOPP/AP below 1.5 vs in 77% using aldosterone/cortisol ratio (A/C)OPP/(A/C)P below 1.5. The absence of CL suppression was associated with a lower rate of response to adrenalectomy in terms of clinical and biochemical parameters with difference in clinical cure (55% vs 13% P = .0003) and overall cure (35% vs 9%, P = .0084) using AOPP/AP, but not when using (A/C)OPP/(A/C)P. CONCLUSIONS Stimulation with ACTH is useful to improve selectivity of AVS but can frequently modify interpretation of lateralization. Basal ratios are as important as post-ACTH ratios to set an indication of adrenalectomy. AOPP/AP is superior to (A/C)OPP/(A/C)P to assess contralateral suppression. Infrequent CL suppression reveals frequent occurrence of contralateral hyperplasia in lateralized cases and helps predict postoperative outcomes.

Abstract
Primary aldosteronism (PA) is the most common cause of endocrine hypertension; it has been reported in more than 11% of referred hypertensive patients. PA may be caused by unilateral adrenal involvement [aldosterone producing adenoma (APA) or unilateral adrenal hyperplasia (UAH)], and bilateral disease (idiopathic adrenal hyperplasia). Only patients with unilateral adrenal hypersecretion may be cured by unilateral adrenalectomy, while patients with bilateral and non-surgically correctable PA are usually treated by mineralocorticoid receptor antagonists; thus the distinction between unilateral and bilateral aldosterone hypersecretion is crucial. Most experts agree that the referral diagnostic test for lateralization of aldosterone hypersecretion should be adrenal venous sampling (AVS) because the interpretation of other imaging techniques [computed tomography (CT), magnetic resonance imaging (MRI) and scintigraphy] may lead to inappropriate treatment. Adrenalectomy represents the elective treatment in unilateral PA variants. Laparoscopic surgery, using transperitoneal or retroperitoneal approaches, is the preferred strategy. Otherwise, the indications to laparoscopic unilateral total or partial adrenalectomy in patients with unilateral PA remain controversial. Adrenalectomy is highly successful in curing the PA, with correction of hypokalemia in virtually all patients, cure of hypertension in about 30-60% of cases, and a marked improvement of blood pressure values in the remaining patients. Interestingly, in several papers the outcomes of surgery focus only on blood pressure changes and the normalization of serum potassium levels is often used as a surrogate of PA recovery. However, the goal of surgery is the normalization of aldosterone, because chronically elevated levels of this hormone can lead to cardiovascular complications, independently from blood pressure levels. Thus, we strongly advocate the need of considering the postoperative normalization of aldosterone-renin ratio (ARR) as the main endpoint for determining outcomes of PA.

Abstract
The renin-angiotensin-aldosterone system (RAAS) is a major regulator of blood pressure control, fluid, and electrolyte balance in humans. Chronic activation of mineralocorticoid production leads to dysregulation of the cardiovascular system and to hypertension. The key mineralocorticoid is aldosterone. Hyperaldosteronism causes sodium and fluid retention in the kidney. Combined with the actions of angiotensin II, chronic elevation in aldosterone leads to detrimental effects in the vasculature, heart, and brain. The adverse effects of excess aldosterone are heavily dependent on increased dietary salt intake as has been demonstrated in animal models and in humans. Hypertension develops due to complex genetic influences combined with environmental factors. In the last two decades, primary aldosteronism has been found to occur in 5% to 13% of subjects with hypertension. In addition, patients with hyperaldosteronism have more end organ manifestations such as left ventricular hypertrophy and have significant cardiovascular complications including higher rates of heart failure and atrial fibrillation compared to similarly matched patients with essential hypertension. The pathophysiology, diagnosis, and treatment of primary aldosteronism will be extensively reviewed. There are many pitfalls in the diagnosis and confirmation of the disorder that will be discussed. Other rare forms of hyper- and hypo-aldosteronism and unusual disorders of hypertension will also be reviewed in this article.

Abstract
Adrenal venous sampling is recommended by current guidelines to identify surgically curable causes of hyperaldosteronism but remains markedly underused. Key factors contributing to the poor use of adrenal venous sampling include the prevailing perceptions that it is a technically challenging procedure, difficult to interpret, and can be complicated by adrenal vein rupture. In addition, the lack of uniformly accepted standards for the performance of adrenal venous sampling contributes to its limited use. Hence, an international panel of experts working at major referral centers was assembled to provide updated advice on how to perform and interpret adrenal venous sampling. To this end, they were asked to use the PICO (Patient or Problem, Intervention, Control or comparison, Outcome) strategy to gather relevant information from the literature and to rely on their own experience. The level of evidence/recommendation was provided according to American Heart Association gradings whenever possible. A consensus was reached on several key issues, including the selection and preparation of the patients for adrenal venous sampling, the procedure for its optimal performance, and the interpretation of its results for diagnostic purposes even in the most challenging cases.

Abstract
PURPOSE OF REVIEW To describe the current indications for adrenal vein sampling (AVS), variability in institutional protocols for performing the procedure, shortage of expert interventional radiologists trained in this procedure, pitfalls in technique and strategies to improve success. A major emphasis of the review will focus on the interpretation of the AVS results. RECENT FINDINGS Published protocols for performance of the AVS procedure and variability in the diagnostic criteria differentiating aldosterone-producing adenoma from bilateral adrenal hyperplasia vary significantly. Inability to catheterize the right adrenal vein is the major reason for technical failure of AVS. Preplanning computed tomography, stat intraprocedural cortisol levels and cone-beam computed tomography are helpful in identifying the right adrenal vein. The administration of adrenocorticotropic hormone stimulation during AVS varies significantly between different studies. SUMMARY More interested interventional radiologists need to acquire the necessary technical expertise for AVS due to increased demand for the procedure, which is the diagnostic reference standard for primary aldosteronism. Unresolved issues include variability in the AVS procedure protocol, use of adrenocorticotropic hormone stimulation and standardization of the interpretation of the results. Despite all these variables, many different approaches still appear to be clinically successful, as indicated by the extensive published reports.

Abstract
Primary aldosteronism is the most frequent cause of secondary arterial hypertension. As adrenal imaging has been shown to have only limited value for differential diagnosis, adrenal vein sampling (AVS) has been implemented as a gold standard in the guidelines. However, AVS is a not well-standardized technique, and success rates vary in a wide range. Successful AVS procedures presuppose careful preparation and operational efficiency in an interdisciplinary team. Besides ruling out malignancy, multidetector-row helical computed tomography facilitates the localization of the adrenal veins. Rapid cortisol measurement has been shown to increase cannulation rates. The values of cosyntropin stimulation and bilateral simultaneous versus sequential catheterization remain unclear, but consistency is important. AVS should be performed in specialized centers by a limited number of radiologists in order to ensure success rates of at least 70%. Standardization of cutoff values should be accomplished through a consensus statement for consistent decision-making in patient care.

Abstract
OBJECTIVE Adrenalectomy for unilateral primary aldosteronism cures hypertension in less than 50% of patients, but improvement is observed in most of the remaining ones. Our goal was to quantify the blood pressure (BP) decrease adjusted for medication changes following adrenalectomy and to identify preoperative predictors of this outcome. METHODS We analyzed simultaneous changes in BP and medication by reviewing the records of 156 consecutive patients who had undergone adrenalectomy for unilateral primary aldosteronism in one center between 2001 and 2009 for whom postoperative follow-up data were available. RESULTS Median [interquartile range] baseline SBP was 149 [135-160] mmHg on drugs from two [1-3] different classes. After adrenalectomy, SBP decreased by 21 [5-31] mmHg and the number of drug classes administered, by one [0-2]. The decrease in SBP, adjusted for the change in the number of drug classes, was 26 [14-36] mmHg. Each drug class dropped after surgery was equivalent to a 5 mmHg SBP decrease. Patients with higher preoperative BP or serum sodium levels experienced a greater BP decrease after adrenalectomy. Adrenalectomy cured hypertension in 68 (44%) patients. Hypertension was less likely to be cured in patients with a longer history of hypertension, higher preoperative BP levels, larger number of drug classes, or lower urinary aldosterone levels. CONCLUSION Although patients with severe hypertension are likely to derive considerable benefits from adrenalectomy in terms of BP or treatment reduction, they should be warned that hypertension cure is unlikely.

Abstract
BACKGROUND A stress reaction involving increased cortisol release, which has not been documented thus far, might affect the assessment of selectivity of catheterization during adrenal venous sampling (AVS). OBJECTIVE To investigate whether an ACTH-driven cortisol release occurs during AVS and whether it influences the assessment of selectivity by the step-up of cortisol (plasma cortisol concentrations, PCC) between the adrenal vein blood (PCC(SIDE)) and the inferior vena cava (PCC(IVC)), e.g. the selectivity index (SI). DESIGN AND METHODS We determined the SI in samples obtained simultaneously at starting AVS (t-15) and again after 15 min (t0) in 34 consecutive patients with proven aldosterone-producing adenoma. We then calculated the SI with PCC(SIDE) obtained at t-15 and at t0, and the PCC(IVC) values obtained at the different time point, thus simulating sequential AVS. RESULTS The PCC(SIDE) and the SI fell significantly from t-15 to t0 on both the sides. When PCC(SIDE) obtained at t-15 was combined with PCC(IVC) at t0, the SI values were higher than those obtained with simultaneously drawn samples. This led to label as selective more AVS studies than with bilaterally simultaneous data, especially when using higher cutoffs for the SI. CONCLUSIONS A transient increase in cortisol release from both adrenal glands occurs in the majority of the patients who undergo AVS. This stress reaction can influence the assessment of both the selectivity of the catheterization during the sequential AVS technique and the lateralization of aldosterone excess.

Abstract
Primary aldosteronism is now thought to be the commonest potentially curable and specifically treatable form of hypertension. The detection of primary aldosteronism is of utmost importance not only because it provides an opportunity for a targeted treatment, but also because it has been demonstrated that patients with primary aldosteronism are more prone to cardiovascular events and target organ damage than essential hypertensives. Normalization of blood pressure and hypokalemia should not be the only goal of treatment. Normalization of circulating aldosterone or mineralocorticoid blockade is necessary to prevent aldosterone-induced tissue damage that occurs independent of blood pressure. This review will focus on the current understanding and comprehensive management review of primary aldosteronism, highlighting the new evidence that has become recently available.

Abstract
Hypertension is a very common disease, leading to significant morbidity with reduction in quality of life. In addition to being a major cause of morbidity and mortality, hypertension places a heavy burden on health care systems, families, and society as a whole. In patients with hypertension, the ability to identify a contributing or secondary cause that is potentially curable or amenable to specific forms of management is of great importance. Endocrine hypertension has emerged as one of the common forms of secondary hypertension. Primary aldosteronism, pheochromocytoma and Cushing's syndrome are among the common causes of endocrine hypertension. The application of new clinical, biochemical, and radiologic approaches has significantly advanced our understanding of the pathophysiology and clinical spectrum of these diseases and improved the management strategies of these challenging conditions.

Abstract
CONTEXT 18-Oxocortisol (18-oxoF) is a derivative of cortisol (F) that is produced by aldosterone synthase (CYP11B2). The potential for this steroid as a biomarker for differentiating patients with aldosterone-producing adenoma (APA) from those with idiopathic hyperaldosteronism (IHA) has not been examined. OBJECTIVES We measured 18-oxoF, aldosterone, and F in plasma from adrenal vein sampling (AVS) of patients with primary aldosteronism. We compared 18-oxoF levels and 18-oxoF/F ratios for their potential to differentiate APA from IHA. DESIGN, SETTING, AND SUBJECTS This study measured 18-oxoF, F, and aldosterone in AVS obtained from patients with unilateral APA (14 cases) or bilateral IHA (seven cases, 14 samples total) using liquid chromatography-tandem mass spectrometry and RIA analyses. RESULTS The levels of 18-oxoF and the ratios of 18-oxoF/F, before and after ACTH stimulation, were significantly higher in blood-draining APA than in those from the contralateral adrenal glands and from adrenal glands with IHA. CONCLUSIONS The 18-oxoF levels and ratios of 18-oxoF/F in AVS samples can be a clinically useful biomarker for differentiating APA from IHA and for determining the localization or lateralization of APA in patients with primary aldosteronism.

Abstract
A few simple rules can allow physicians to successfully identify many patients with arterial hypertension caused by PA among the so-called essential hypertensive patients. The hyperaldosteronism and the hypokalemia can be cured with adrenalectomy in practically all of these patients. Moreover, in a substantial proportion of them, the blood pressure can be normalized or markedly lowered if a unilateral cause of PA is discovered. Hence, the screening for PA can be rewarding both for the patient and for the clinician, particularly in those cases where hypertension is severe and/or resistant to treatment, in which the removal of an APA can allow blood pressure to be brought under control despite withdrawal of, or a prominent reduction in, the number and doses of antihypertensive medications.

Abstract
Primary aldosteronism is much more common than previously thought. The high prevalence of primary aldosteronism, the damage this condition does to the heart, blood vessels and kidneys (which causes a high rate of cardiovascular events), along with the notion that a timely diagnosis followed by an appropriate therapy can correct the arterial hypertension and hypokalemia, justify efforts to search for primary aldosteronism in many patients with hypertension. Most centers can use a cost-effective strategy to screen for patients with primary aldosteronism. By contrast, the identification of primary aldosteronism subtypes, which involves adrenal-vein sampling, should only be undertaken at tertiary referral centers that have experience in performing and interpreting this test. The identification of a curable form of primary aldosteronism can be beneficial for the patient. In some subgroups of patients with hypertension who are at high risk of primary aldosteronism or can benefit most from an accurate diagnosis, an aggressive diagnostic approach is necessary.

Abstract
Primary hyperaldosteronism is known to be one of the commonnest causes of arterial hypertension. The authors propose a diagnostic protocol for primary hyperaldosteronism and a method for comparative selective blood sampling from adrenal veins. This method is described as the sole tool for differential diagnostics of different nosological forms of primary hyperaldosteronism. A clinical case of idiopathic hyperaldosteronism is presented.

Abstract
Primary aldosteronism is unquestionably the most common secondary cause of hypertension, and effective approaches to diagnosis and targeted treatments exist. Even the most conservative estimates of the prevalence of primary aldosteronism, however, indicate that the condition is grossly underdiagnosed. Part of the reason why diagnosis and treatment lag far behind is the lack of expertise, even among endocrinologists and hypertension specialists, in the approach to the patient with possible primary aldosteronism. We will never make an impression on this important problem unless general internists and primary care physicians actively participate in the screening and referral process. A healthcare delivery team need not fear an overwhelming and fruitless battle with an intractable conundrum if a practical and staged approach to workup and treatment is taken. This review discusses the approach we have taken in Dallas, a strategy of targeted screening, referral for positive screens, and individualized management.
