Abstract
INTRODUCTION Adrenal venous sampling (AVS) is used to distinguish unilateral from bilateral aldosterone hypersecretion as a cause of primary aldosteronism (PA). Unilateral disease is treated with adrenalectomy and bilateral hypersecretion managed medically. METHODS We performed a single institution retrospective cohort study of adult patients undergoing adrenalectomy for PA from July 2013 to June 2022. Concordance of imaging findings with AVS was evaluated. Statistical analysis was performed with Mann-Whitney U and chi-squared Fisher's exact. Literature review performed via triple method search strategy. RESULTS Twenty-one patients underwent AVS and adrenalectomy for PA. Two patients did not have imaging findings and 19 were localized with an adenoma. For patients with image localization, AVS was concordant in nine, discordant in four, and nondiagnostic in six. For patients with discordant findings, age range was 35.8 to 72.4 y compared with concordant patient age range of 49.8 to 71.7 y. Overall discordance between imaging results and AVS was 40%. The aldosterone level was associated with concordance with a median of 52 ng/dL compared with 26 ng/dL if discordant (P = 0.002). There was a significant reduction in antihypertensive medications for the entire cohort from a median of three medications (interquartile range 2-4) to 1 medication (interquartile range 1-2), P < 0.001. CONCLUSIONS In this cohort, 40% of patients with selective AVS had discordant imaging and AVS results. Aldosterone level was associated with concordance. Hypertension was significantly improved with a median decrease of two antihypertensives. Our results support performance of AVS on all candidates for adrenalectomy for PA.

Abstract
PURPOSE Adrenal vein sampling (AVS) is used to lateralise and differentiate unilateral from bilateral aldosterone production in primary aldosteronism. The adrenal venous samples are standardised to a peripheral or low inferior vena cava (IVC) sample and compared. It is unknown whether the location of the non-adrenal sample affects the results. This study compares AVS results standardised to the low IVC and right external iliac vein (REIV). METHODS Patients who underwent AVS between March 2021 and May 2023 were included. All procedures were undertaken by a single operator (AA). Demographic data and AVS results were collected from patients' electronic records. Catheterisation success and lateralisation were assessed using both low IVC and REIV samples. Equivalence test was used to compare the cortisol and aldosterone levels. RESULTS Eighty-one patients, (M: F = 38:43), aged between 29 and 74 were included. Bilateral successful adrenal vein cannulation was achieved in 79/81 (97.5%) cases. The mean cortisol levels from the REIV were statistically equivalent although there was a small and not biologically significant difference from the low IVC (respective geometric means 183 nmol/l vs. 185 nmol/l, p = 0.015). This small difference in cortisol may be due to accessory adrenal venous drainage into the IVC. The aldosterone and aldosterone/cortisol ratios were statistically equivalent. There was no discordance in selectivity or lateralisation when the IVC or REIV measurements were used. CONCLUSION The IVC and REIV samples may be used interchangeably during AVS.

Abstract
Objective To compare the diagnostic value of adrenocorticotropic hormone (ACTH) stimulation test (AST) with different doses of ACTH combined with midnight administration of 1 mg dexamethasone for the determination of the subtypes of primary hyperaldosteronism (PA). Methods This is a prospective observational study. Patients diagnosed with PA in the Department of Endocrinology, the First Medical Center of of Chinese PLA General Hospital from January 1, 2020 to September 30, 2022 underwent AST with different doses of ACTH. All patients received 1 mg dexamethasone at midnight for inhibition. Then, the patients were randomly assigned to 25-unit and 50-unit ACTH treatment groups by a ratio of 1:2. Subtype classification and diagnosis of aldosterone-producing adenoma (APA) and idiopathic hyperaldosteronism (IHA) was made on the basis of adrenal venous blood samples and/or postoperative pathology and clinical follow-up findings. Receiver operating characteristics (ROC) curves were plotted to examine the diagnostic efficacy and the difference of AST by varying doses of ACTH in distinguishing APA and IHA. Results A total of 82 patients, including 49 patients with APA (59.8%) and 33 patients with IHA (40.2%), were enrolled. There were 29 patients in the 25-unit ACTH group (35.4%) and 53 patients in the 50-unit ACTH group (64.6%). There were no significant differences in age, sex, blood pressure, minimum serum potassium, and biochemical parameters between the 25-unit and 50-unit groups. After ACTH stimulation, plasma aldosterone concentration (PAC), cortisol (F), and PAC/F at different points of time showed no statistical difference between the two groups (P>0.05). The area under the curve (AUC) of PAC in the 25-unit group was higher than that of PAC/F. The AUC of PAC reached the maximum at 90 minutes (0.948, 95% confidence interval [CI]: 0870-1.000) and the optimal cutoff was 38.0 ng/dL, which had a sensitivity of 92.9% and a specificity of 86.7% for differentiating APA and IHA. Similar to the 25-unit group, the maximum AUC of PAC in the 50-unit group was greater than that of PAC/F. The AUC of PAC reached the maximum 90 minutes (0.930, 95% CI: 0.840-0.994) and the optimal cutoff was 39.6 ng/dL, which had a sensitivity of 91.2% and a specificity of 83.3%. The AUC of PAC at different points of time in the 25-unit ACTH group (0.862-0.948) was greater than that of 50-unit ACTH group (0.823-0.930), but the difference was not statistical significance. Conclusion AST with 25-unit or 50-unit ACTH combined with small-dose dexamethasone can be used in PA subtype determination, ie, differentiation between APA and IHA. The optimal PAC cut-off values for 25-unit or 50-unit ACTH are similar, being 38.0 ng/dL and 39.6 ng/dL, respectively, and both cutoff values show higher sensitivity and specificity at 90 min. The AST with 25-unit ACTH has the smaller dose and the better safety. Therefore, it is recommended for the diagnosis of PA subtypes.

Abstract
Primary hyperaldosteronism (PAH) is an important cause of secondary hypertension (HTN). The study of the same requires a high clinical suspicion in addition to a hormonal study that confirms hormonal hypersecretion. It is important to start the appropriate treatment once the diagnosis is confirmed, and for this is necessary to demonstrate whether the hormonal hypersecretion is unilateral (patients who could be candidates for surgical treatment) or bilateral (patients who are candidates for pharmacological treatment only). At the Hospital del Mar since 2016 there has been a multidisciplinary work team in which Nephrologists, Endocrinologists, Radiologists and Surgeons participate to evaluate cases with suspected hyperaldosteronism and agree on the best diagnostic-therapeutic approach for these patients, including the need for adrenal vein sampling, which is a technique that in recent years has become the gold standard for the study of PAH. In the present study we collect the experience of our centre in performing AVC and its usefulness for the management of these patients.

Abstract
Background Primary aldosteronism (PA) is one of the main causes of secondary endocrine hypertension, especially refractory hypertension. Increased autonomous secretion leads to increased blood pressure and proinflammatory effects on different organ systems, including the cardiovascular system. However, because of its diverse clinical manifestations or the combination of other conditions, it sometimes causes problems for correct diagnosis. Therefore, we report and review the characteristics of some atypical and uncommon special case cases related to proaldosterone to provide clinical ideas for correct diagnosis and decision-making of proaldosterone. Case Description A 38-year-old male patient with fatigue and bilateral lower extremity pain came to the clinic and was found to have abnormal thyroid function, low blood potassium, elevated blood pressure, and also combined with rhabdomyolysis (RM) after further improvement of functional tests and imaging tests was diagnosed with an adrenal cortical adenoma (aldosteronism), hypertension secondary to PA, hypokalemia secondary to PA, RM, and subacute thyroiditis. After laparoscopic resection of a unilateral adrenal adenoma, the patient's blood pressure and blood potassium gradually returned to normal, and thyroid function returned to normal without additional intervention. Conclusions Early screening should be performed for the high-risk population of PA to prevent the occurrence of RM and other serious complications caused by the progression of the disease. For patients with RM, the primary disease should be approached radically and should be based on symptomatic treatment. For RM syndrome associated with thyroid dysfunction, the etiology of the thyroid dysfunction should be actively identified to guide appropriate clinical management.

Abstract
PURPOSE Central Serous Chorioretinopathy (CSCR) is a prevalent ocular disease classified in the pachychoroidal spectrum with an elevated morbidity. Although the pathogenesis is yet unclear, mineralocorticoid-mediated pathways seem to be implicated. Primary hyperaldosteronism (PA) is a relatively frequent, albeit underdiagnosed, cause of hypertension, and has a specific therapy. A previous study assessed the prevalence of CSCR-like signs in a cohort of patients diagnosed with PA and found signs in seven out of thirteen PA patients. The present study aims to study the contrary, screening for PA in a cohort of acute CSCR patients. METHODS Between March 2017 and September 2018 all patients with acute CSCR were systematically referred to Endocrinology Department after complete ophthalmic evaluation was performed with visual acuity, spectral domain optical coherence tomography, fundus autofluorescence, fluorescein and indocyanine green angiography. The method applied for detection of PA was the 2-h 25 mg captopril challenge test (CCT). RESULTS Of the nineteen patients screened, two of them had a CCT positive for PA (2-h plasma aldosterone/renin ratio > 50 and/or an aldosterone level of 130 pg/ml or higher), and were treated with mineralocorticoid receptor antagonists (MRA). No ophthalmic pattern was identified in them in terms of time to resolution, recurrences or features of the acute episode. The only differential feature in the fundus of PA patients was pathological arteriovenous crossings (AVC) as well as elevated BP levels. CONCLUSION a high incidence of PA was found among acute CSCR patients. This preliminary study suggests a need for screening for PA in hypertensive CSCR patients in real clinical practice.

Abstract
Background Despite technical advances, day surgery still accounts for <1 % of adrenal procedures. We investigated feasibility and safety of same day adrenalectomy (SDA). Methods Between We recruited 30 patients with primary hyperaldosteronism (PHA) or Cushing's syndrome (CS) into a prospective matched, single centre cohort study to evaluate the impact of exposure to a same day discharge pathway (SDA cohort; n = 10) or inpatient adrenalectomy (PIPA cohort; n = 20). We compared results to a matched cohort (n = 40) from our prospective in-patient adrenalectomy registry (RIPA cohort). Results Mean age was 51.3 ± 8.5 years, with 43 % female, 3.3 % ASA I and 96.7 % ASA II. Lesion size was 17 ± 9 mm (range 5-40 mm). 80 % of patients presented with PHA. The predefined primary endpoint (discharge on same calendar day without major complications, emergency presentation or readmission) was achieved in 100 % of SDA, but none of the in-patients (χ2 = 57; p < 0.0001). The secondary endpoint (discharge within 23 h of surgery without major complications, emergency presentation or readmission) was achieved in 100 % of SDA, 90 % of PIPA (n.s.), 33 % of RIPA (33 %; χ2 = 14.6 p < 0.001), and 51.5 % of IPA patients (χ2 = 8.5 p < 0.01). Combining SDA and PIPA cohorts, 93.3 % of treatment episodes met widely used (WHO, United States) definitions of day surgery as completion of the hospital care episode within 23 h. Patients admitted for SDA were highly satisfied (100 %). Conclusion Same day discharge after adrenalectomy is feasible, safe, and well-perceived in appropriately selected patients with PHA and Cushing's syndrome.

Abstract
Secondary hypertension occurs in 5% to 10% of all patients with hypertension. Given the majority of patients with hypertension will not have a secondary cause, only select patients with specific characteristics should be screened. The causes include a range of abnormalities, some are quite rare, such as pheochromocytoma, while others are much more common, such as chronic kidney disease. When considering which disorders to test for, it is important to incorporate the clinical history, family history, and prevalence of each disease. Treatment is specific to the underlying cause and includes medications, procedures, surgery, and device therapies.

Abstract
OBJECTIVE To evaluate the indication and the resources for the screening/diagnosis of primary aldosteronism (PA) in Endocrinology units in Spain. MATERIAL AND METHODS An anonymous 2-phase (2020/2021) online survey was conducted by the AdrenoSEEN group among SEEN members with data about screening, confirmation tests, availability of catheterisation and the treatment of PA. RESULTS Eighty-eight (88) specialists completed the survey. Plasma aldosterone concentration and plasma renin activity were available at all centres; urinary aldosterone was available in 55% of them. The most frequent indications for determining the aldosterone/renin ratio (ARR) were adrenal incidentaloma (82.6%), hypertension with hypokalaemia (82.6%), hypertension in patients <40 years (79.1%) and a family history of PA (77.9%). 61% and 18% of the respondents used an ARR cut-off value of PA of ≥30 and 20ng/dl per ng/mL/, respectively. The intravenous saline loading test was the most commonly used confirmatory test (66.3%), followed by the captopril challenge test (24.4%), with the 25mg dose used more than the 50mg dose (65% versus 35%). 67.4% of the participants confirmed the availability of adrenal vein catheterization (AVC). 41% of this subgroup perform it with a continuous infusion versus 30.5% with an ACTH (1-24) bolus, whereas 70.3% employ sequential adrenal vein catheterization. 48% of the participants reported an AVC success <50%. Total laparoscopic adrenalectomy was the treatment of choice (90.6%), performed by specialists in General and Digestive Surgery specialising in endocrinological pathology. CONCLUSION PA screening and diagnostic tests are extensively available to Spanish endocrinologists. However, there is a major variability in their use and in the cut-off points of the diagnostic methods. The AVS procedure remains poorly standardised and is far from delivering optimal performance. Greater standardisation in the study and diagnosis of PA is called for.

Abstract
OBJECTIVE To analyze the evolution of the cardiometabolic profile of patients with primary hyperaldosteronism (PA) after the treatment with surgery and with mineralocorticoid receptor antagonists (MRA). DESIGN Retrospective multicentric study of patients with PA on follow-up in twelve Spanish centers between 2018 and 2020. RESULTS 268 patients with PA treated by surgery (n = 100) or with MRA (n = 168) were included. At baseline, patients treated with surgery were more commonly women (54.6% vs 41.7%, P = 0.042), had a higher prevalence of hypokalemia (72.2% vs 58%, P = 0.022) and lower prevalence of obesity (37.4% vs 51.3%, P = 0.034) than patients treated with MRA. Adrenalectomy resulted in complete biochemical cure in 94.0% and clinical response in 83.0% (complete response in 41.0% and partial response in 42.0%). After a median follow-up of 23.6 (IQR 9.7-53.8) months, the reduction in blood pressure (BP) after treatment was similar between the group of surgery and MRA, but patients surgically treated reduced the number of antihypertensive pills for BP control more than those medically treated (∆antihypertensives: -1.3 ± 1.3 vs 0.0 ± 1.4, P < 0.0001) and experienced a higher increased in serum potassium levels (∆serum potassium: 0.9 ± 0.7 vs 0.6 ± 0.8mEq/ml, P = 0.003). However, no differences in the risk of the onset of new renal and cardiometabolic comorbidities was observed between the group of surgery and MRA (HR = 0.9 [0.5-1.5], P = 0.659). CONCLUSION In patients with PA, MRA and surgery offer a similar short-term cardiovascular protection, but surgery improves biochemical control and reduces pill burden more commonly than MRA, and lead to hypertension cure or improvement in up to 83% of the patients.

Abstract
Primary aldosteronism (PA) is the most common cause of secondary arterial hypertension. Moreover, it is associated with a higher cardio-metabolic risk than the observed in patients with essential arterial hypertension (EHT). Therefore, a high index of clinical suspicion for PA is mandatory. If an elevated aldosterone/renin ratio is confirmed, confirmatory tests should be performed, with the exception in those patients with florid PA, with, with spontaneous hypokalaemia, plasma aldosterone > 20 ng/dL and suppressed renin, in whom this step would not be strictly necessary. Intravenous saline infusion test or captopril test are the commonly used confirmatory tests. The last step in the diagnosis of PA is the localization study, being the computerized axial tomography (CT) of the adrenal glands the initial test of choice, and adrenal venous sampling (AVS), the definitive localization test in most cases. This review summarizes the available data about the diagnosis of PA, from screening to confirmatory study and localization.

Abstract
BACKGROUND Conventional diagnostic approaches for adrenal tumors require multi-step processes, including imaging studies and dynamic hormone tests. Therefore, this study aimed to discriminate adrenal tumors from a single blood sample based on the combination of liquid chromatography-mass spectrometry (LC-MS) and machine learning algorithms in serum profiling of adrenal steroids. METHODS The LC-MS-based steroid profiling was applied to serum samples obtained from patients with nonfunctioning adenoma (NFA, n=73), Cushing's syndrome (CS, n=30), and primary aldosteronism (PA, n=40) in a prospective multicenter study of adrenal disease. The decision tree (DT), random forest (RF), and extreme gradient boost (XGBoost) were performed to categorize the subtypes of adrenal tumors. RESULTS The CS group showed higher serum levels of 11-deoxycortisol than the NFA group, and increased levels of tetrahydrocortisone (THE), 20α-dihydrocortisol, and 6β-hydroxycortisol were found in the PA group. However, the CS group showed lower levels of dehydroepiandrosterone (DHEA) and its sulfate derivative (DHEA-S) than both the NFA and PA groups. Patients with PA expressed higher serum 18-hydroxycortisol and DHEA but lower THE than NFA patients. The balanced accuracies of DT, RF, and XGBoost for classifying each type were 78%, 96%, and 97%, respectively. In receiver operating characteristics (ROC) analysis for CS, XGBoost, and RF showed a significantly greater diagnostic power than the DT. However, in ROC analysis for PA, only RF exhibited better diagnostic performance than DT. CONCLUSION The combination of LC-MS-based steroid profiling with machine learning algorithms could be a promising one-step diagnostic approach for the classification of adrenal tumor subtypes.

Abstract
PURPOSE To perform a systematic review and meta-analysis to quantify the technical success rate of adrenal venous sampling (AVS) with and without intraprocedural computed tomography (CT). METHODS A systematic search of the Medline, Scopus, EMBASE, and Web of Science databases for comparative studies using intraprocedural CT was undertaken. More than 1,000 records were screened using titles and abstracts. Full texts of 121 studies were reviewed and 14 eligible studies were identified. Nine studies had adequate comparative data and were included in the meta-analysis. RESULTS A research synthesis was performed and data from 809 patients were pooled in multiple random effect models. Overall success rate of AVS without and with intraprocedural CT was 72.7% (59.3-83.0%) and 92.5% (86.6-95.9), respectively. The addition of intraprocedural CT increased the technical success rate by 19.8% (P < 0.001), with an odds ratio (OR) of 5.5 (3.3-9.2; P < 0.01). In meta-regression, odds of success with intraprocedural CT was associated with younger age (beta: 0.16 ± 0.05; P:0.001), higher body mass index (BMI; beta:0.08 ± 0.03; P:0.002), and higher selectivity index (defined as the ratio of cortisol in the adrenal vein to that in the inferior vena cava; beta:0.35 ± 0.08, P < 0.001). We found a linear inverse association between operator's success without CT and improved success with intraprocedural CT (R2: 0.86). CONCLUSIONS Intraprocedural CT is not required for every case, but can be performed in difficult cases or when operators' success is limited. The benefit was more pronounced in younger patients with higher BMI, female gender, and with higher selectivity. LEVEL OF EVIDENCE III Systematic review and meta-analysis of non-randomized clinical trials.

Abstract
PURPOSE To evaluate the feasibility and effect of an approach to adrenal venous sampling (AVS) analysis by combining established selective cortisol and aldosterone indices with the acquisition of a collimated C-arm CT(CACTColl). METHODS Overall, 107 consecutive patients (45f,62 m; 54 ± 10 years) undergoing 111 AVS procedures without hormonal stimulation from 7/13 to 2/20 in a single institution were retrospectively analysed. Hormone levels were measured in sequential samples of the suspected adrenal veins and right iliac vein, and selectivity indices (SI) computed. Stand-alone SICortisol and/or SIAldosterone ≥ 2.0 as well as SICortisol and/or SIAldosterone ≥ 1.1 combined with positive right-sided CACTColl of the adrenals (n = 80; opacified right adrenal vein) were defined as a successful AVS procedure. Radiation exposure of CACT was measured via dose area product (DAP) and weighed against an age-/weight-matched cohort (n = 66). RESULTS Preliminary success rates (SICortisol and/or SIAldosterone ≥ 2.0) were 99.1% (left) and 72.1% (right). These could be significantly increased to a 90.1% success rate on the right, by combining an adjusted SI of 1.1 with a positive CACTColl proving the correct sampling position. Sensitivity for stand-alone collimated CACT (CACTColl) was 0.93, with 74/80 acquired CACTColl confirming selective cannulation by adrenal vein enhancement. Mean DAPColl_CACT measured 2414 ± 958 μGyxm2, while mean DAPFull-FOV_CACT in the matched cohort measured 8766 ± 1956 μGyxm2 (p < 0.001). CONCLUSION Collimated CACT in AVS procedures is feasible and leads to a significant increase in success rates of (right-sided) selective cannulation and may in combination with adapted hormone indices, offer a successful alternative to previously published AVS analysis algorithms with lower radiation exposure compared to a full-FOV CACT.

Abstract
BACKGROUND The current first-line screening test for primary hyperaldosteronism is the plasma aldosterone:renin ratio; however, renin assays have several disadvantages and the ARR is affected by medications and physiological factors. Angiotensin II is a key biologically active hormone in the renin-angiotensin-aldosterone system. It has been suggested that measurement of equilibrium levels of this peptide, involving an in vitro incubation of serum prior to analysis, may provide a better marker of renin-angiotensin-aldosterone system activity than renin. METHODS An eqAng II LC-MS/MS assay was developed, optimized and validated. Serum samples were incubated at 37°C for 45 min prior to stabilization with cold EDTA solution, solid phase extraction and LC-MS/MS analysis. Stability in whole blood and the effect of cryoactivation were assessed. For comparison to the current screening test, 150 anonymized patients' samples were analysed for eqAng II, renin activity and aldosterone (all by LC-MS/MS). RESULTS The assay had good precision, minimal bias and acceptable recovery. EqAng II did not change significantly when whole blood samples were stored for up to 72 h, and cryoactivation was only observed for pregnant patients. EqAng II was significantly correlated with renin, and the aldosterone:eqAng II ratio had a strong positive correlation with the aldosterone:renin ratio. CONCLUSIONS An LC-MS/MS assay for eqAng II has been developed which shows promise as an alternative screening test for primary hyperaldosteronism. Compared to renin assays, it is quicker, simpler and less likely to be affected by anti-hypertensive medications. Further clinical validation in hypertensive patients would be required prior to implementation.

Abstract
Primary aldosteronism is associated with higher cardiovascular and renal morbidity and mortality than essential hypertension in age- and sex-matched patients with the same degree of blood pressure elevation. Therefore, it is essential to establish a specific treatment to avoid the deleterious effects of aldosterone excess. Although adrenalectomy is generally considered the treatment of choice in cases of primary aldosteronism due to unilateral disease, several aspects and circumstances should be taken into account that may make medical treatment more appropriate. Among them, in this review we mention the limited experience and efficacy, and the potential risks of adrenal vein sampling; the risks and low efficacy of adrenalectomy; the high safety and efficacy of medical treatment and some special situations such as primary aldosteronism during pregnancy, in patients of advanced age or hereditary forms of primary aldosteronism, in which medical treatment is considered especially indicated as the first line therapy. The main studies comparing medical and surgical treatment in primary aldosteronism are also discussed.

Abstract
A 36-year-old woman presented at 16 weeks' gestation with severe hypertension. In comparison to the non-pregnant reference normal ranges, potassium was 3.1-3.9 mmol/L, aldosterone 2570-3000 pmol/L (N 250-2885) renin was unsuppressed (24-76.4 ng/L (N1.7-23.9)), with aldosterone to renin ratios in the reference range. An adrenal MRI scan demonstrated a 1.8 × 1.4 cm left adrenal adenoma. Primary aldosteronism was strongly suspected and surgery considered. However, she was managed conservatively with labetalol and modified-release nifedipine with no obstetric complications. Post-partum blood pressures remained elevated with normal aldosterone (539 pmol/L), unsuppressed renin (5.2 ng/L) and normal aldosterone-to-renin ratio (104 (N < 144)). Suspected primary hyperaldosteronism is challenging to investigate and manage in pregnancy. The accepted screening and confirmatory tests are either contraindicated or not validated in pregnancy. Pregnancy has significant effects on the renin-angiotensin-aldosterone pathway leading to physiologic elevations in both aldosterone and renin. While primary hyperaldosteronism has been associated with poor pregnancy outcomes, optimal management in pregnancy is not clearly established.

Abstract
Background Conn’s syndrome is a curable condition if identified properly. It is characterized by autonomous secretion of aldosterone from the adrenal gland cortex. Its morbidity is related to the increased risk of cardiovascular diseases. Case presentation We report the case of a 48-year-old man of African descent presenting with generalized tonic-clonic seizure and coma secondary to hypertensive encephalopathy. A biochemical evaluation revealed a very high aldosterone level and an undetectable renin level, both are compatible with primary aldosteronism. The presentation of the following confirms the diagnosis of primary aldosteronism: spontaneous hypokalemia, an undetectable renin level, and a high aldosterone level. Abdominal computed tomography revealed a left adrenal adenoma. Adrenal venous sampling confirmed lateralization of aldosterone excretion from the left adrenal gland. Our patient underwent left laparoscopic adrenalectomy that confirmed a left functional adrenal adenoma. After 12 months of follow up, his hypertension was controlled on only one antihypertensive drug which was down from four drugs preoperatively. Conclusion Conn’s syndrome, in this case, was complicated by coma secondary to seizure. Adrenalectomy normalized the hypokalemia and improved resistant hypertension. Potassium supplementation and several antihypertensives were discontinued as our patient became normokalemic and normotensive on one antihypertensive agent.

Abstract
We present a case of persistent postpartum hypertension found to be secondary to primary hyperaldosteronism in a woman with a history of recurrent hypertensive disorders of pregnancy and associated fetal complications. Our systematic review revealed only 18 cases of primary aldosteronism diagnosed in women with postpartum hypertension, suggesting that this disorder is under-studied in the postpartum period. A review of these cases suggests that women with primary hyperaldosteronism commonly present with hypertensive disorders of pregnancy, but may only be identified de novo postpartum. However, a high index of suspicion is needed to diagnose primary hyperaldosteronism in the postpartum period, guided by a woman's obstetric history.

Abstract
PURPOSE OF REVIEW Primary aldosteronism (PA) is a common form of hypertension characterized by autonomous aldosterone secretion from one or both adrenal glands. The purpose of this review is to synthesize recent research findings regarding cardiovascular disease risk in PA both pre- and post-targeted therapy. RECENT FINDINGS Previously considered a rare disease, recent prevalence studies demonstrate that PA is actually a very common, yet vastly under-diagnosed, etiology of hypertension. Prior to targeted therapy, PA is associated with substantially higher rates of cardiovascular disease compared with essential hypertension. Surgical adrenalectomy is highly effective in curing or improving hypertension as well as mitigating cardiovascular disease risk in patients with unilateral PA. For the remainder of PA patients, MR antagonists are recommended; however, several recent studies have brought into question their effectiveness in improving cardiovascular outcomes. PA is a common cause of hypertension that leads to disproportionately high rates of cardiovascular disease. Future studies are needed to enhance the clinical approach to both identification and treatment of patients with PA to optimize long-term cardiovascular outcomes.

Abstract
Less than 15% of hypertension cases in children are secondary to a primary hyperaldosteronism. This is idiopathic in 60% of the cases, secondary to a unilateral adenoma in 30% and 10% remaining by primary adrenal hyperplasia, familial hyperaldosteronism, ectopic aldosterone production or adrenocortical carcinoma.To date, four types of familial hyperaldosteronism (FH I to FH IV) have been reported. FH III is caused by germline mutations in KCNJ5, encoding the potassium channel Kir3.4. The mutations cause the channel to lose its selectivity for potassium, allowing large quantities of sodium to enter the cell. As a consequence, the membrane depolarizes, voltage-gated calcium channels open, calcium enters the cell, initiating the cascade that leads to aldosterone synthesis. Somatic mutations in KCNJ5 has also been described in aldosterone-producing adenomas. The most frequent presentation of FH III is with severe hyperaldosteronism symptoms and resistance to pharmacological therapy which leads to bilateral adrenalectomy. We will review current literature and describe a child with FH III due to a novel de novo deletion in KCNJ5 with wild phenotype as a sign of clinical variability of this disease.

Abstract
Panic attacks and panic disorders are common in the general population. However, the presence of panic attacks associated with primary hyperaldosteronism has been rarely documented. We describe a patient with new-onset hyperaldosteronism secondary to adrenal adenoma who presented with recurrent panic attacks. The patient underwent adenoma resection, which was the definitive cure for the patient's hyperaldosteronism and panic attacks. Clinicians should include hyperaldosteronism on the differential for medical etiologies of panic attacks. Further research is needed to elucidate the mechanistic relationship between primary hyperaldosteronism and panic attacks.

Abstract
OBJECTIVES To evaluate long-term results of adrenalectomy for primary aldosteronism (PA) and to identify prognostic factors associated. METHODS Exhaustive retrospective review of all consecutive patients undergoing adrenalectomy for PA between 2002 and 2013 in our department. All patients underwent preoperative: clinical evaluation (age, sex, height, weight, systolic and diastolic BP under treatment, identification of anti-hypertension treatment), biological evaluation (potassium, renin, aldosterone) and radiological evaluation (CT and/or MRI). Blood pressure was assessed postoperatively at 1 month, 1 year, then at the date of the latest news. The patients were classified into three categories: cured (no antihypertensive therapy in postoperative associated with strictly lower blood pressures of 140/90mmHg), improved (decreased number of drugs or number unchanged but with better blood pressure control), and refractory (no change in the number of drug and blood pressure, or deterioration of one or other of these two parameters). RESULTS We evaluated 43 patients, 23 men and 20 women, with a median follow-up of 74.4 months [16.8 to 141]. Pathological analysis described 34 adenomas (79%), 7 hyperplasias (16%) (5 micro-nodular and 2 macro-nodular) and 2 adrenocortical carcinoma (5%). The postoperative long-term assessment found 20% of cured patients (n=8), 65% of improved (n=26) and 15% of refractory (n=6). Prognostic factors associated with favorable long-term blood pressure outcome were those typically associated with ARS score [preoperative number of anti-hypertension drugs (P=0.005), BMI<25kg/m2 (P=0.009), and duration of hypertension (P=0.007)]. CONCLUSION Adrenalectomy for PA is a long-term effective treatment for blood pressure control. Prognostic factors associated with long-term success are those conventionally described in ARS score. LEVEL OF EVIDENCE 4.

Abstract
PURPOSE Adrenal venous sampling is generally considered the gold standard to identify unilateral hormone production in cases of primary hyperaldosteronism. The aim of this study is to evaluate whether the iodine-131-6-β-iodomethyl-19-norcholesterol (NP-59) test may represent an alternative in selected cases. METHODS Patients submitted to laparoscopic adrenalectomy for suspected primary hyperaldosteronism (n = 27) were retrospectively reviewed. When nuclear medicine tests were preoperatively performed, their results were compared with the histopathologic findings and clinical improvement. RESULTS Nuclear medicine tests were realized in 13 patients. In 11 (84.6%), a planar anterior and posterior NP-59 scintigraphy was performed and a SPECT/TC in two (15.4%). Scintigraphy indicated a preoperative lateralization in 12 out of 13 patients (92.3%). When the value of NP-59 tests was based on pathologic results, it showed a sensitivity of 90.9% and a positive predictive value of 83.3%. When the nuclear medicine test's performance was based on postoperative blood pressure control, both sensitivity and positive predictive value were 91.6%. CONCLUSIONS Nuclear medicine tests represent a useful tool in the preoperative localisation of primary hyperaldosteronism with a high sensitivity and positive predictive value. In patients with contraindications to adrenal venous sampling like contrast allergies, or when it is inconclusive, scintigraphy can represent a useful and non-invasive alternative.

Abstract
OBJECTIVES Primary hyperaldosteronism (PHA) is one of the most common endocrine forms of secondary hypertension. Among the most used confirmatory tests for PHA is urinary aldosterone determination after oral sodium loading test. The primary aim of our study was to investigate if sodium concentrations interfere with urinary aldosterone in an automated competitive immunoassay (Liaison®) as well as to verify the manufacturer's specifications. DESIGN AND METHODS 24-hr urine samples were collected and stored frozen until assayed. Two pools at low and high aldosterone concentrations were prepared. Verification of performance for precision was tested according to Clinical and Laboratory Standards Institute (CLSI) document EP15-A2 and interference with increasing concentrations of NaCl according to CLSI EP7-A2. RESULTS The assay met the quality specifications according to optimal biological variation. Our results show that sodium concentrations up to 200mmol/L do not interfere on urinary aldosterone quantification, but sodium concentrations above 486mmol/L negatively interfere with the test. CONCLUSIONS The Liaison® automated method is useful for aldosterone determination in the PHA confirmatory test, but interferences with NaCl may occur. It is therefore recommended to determine urinary NaCl before measuring urinary aldosterone to avoid falsely low results.

Abstract
BACKGROUND During the course of evaluation for primary hyperaldosteronism, cross-sectional imaging is obtained in efforts to identify patients with an aldosterone producing adenoma (APA). A subset of these patients will have a synchronous, contralateral adrenal abnormality. Adrenal vein sampling (AVS) further guides clinical decision making by identifying unilateral (APA) versus bilateral hypersecretion. In the subset of patients with contralateral adrenal abnormalities, it is unclear how this affects the durability of an adrenalectomy for APA. This study characterizes this group of patients to assess the efficacy of surgical intervention. METHODS A retrospective review of patients undergoing adrenalectomy for APA based on AVS at a university practice. Preoperative and postoperative patient characteristics, laboratory evaluations, imaging results, and final pathology were noted. RESULTS From 2000 to 2011, 103 patients with APA underwent unilateral adrenalectomy. Eighteen patients (17%) had discordant results between AVS and imaging. Most of these patients were male (78%), and the mean age was 57 ± 13 y. Median duration of follow-up was 3.5 y [1 y, 6 y]. All patients with initial hypokalemia were rendered normokalemic after the operation. Four patients increased their antihypertensive regimen during the follow-up period. These patients all had nodular hyperplasia on final pathology. CONCLUSIONS In patients with bilateral adrenal abnormalities who have undergone unilateral adrenalectomy for primary hyperaldosteronism, patients with clear APAs on final pathology appear to have durable outcomes after resection. Conversely, nodular hyperplasia on final pathology may be a risk factor for ongoing aldosterone hypersecretion. An algorithm for biochemical surveillance in this subset of patients should be considered.

Abstract
Hypertension causes significant morbidity and mortality worldwide, owing to its deleterious effects on the cardiovascular and renal systems. Primary hyperaldosteronism (PA) is the most common cause of reversible hypertension, affecting 5%-18% of adults with hypertension. PA is estimated to result from bilateral adrenal hyperplasia in two-thirds of patients, and from unilateral aldosterone-secreting adenoma in approximately one-third. Suspected cases are initially screened by measurement of the plasma aldosterone-renin-ratio, and may be confirmed by additional noninvasive tests. Localization of aldostosterone hypersecretion is then determined by computed tomography imaging, and in selective cases with adrenal vein sampling. Solitary adenomas are managed by laparoscopic or robotic resection, while bilateral hyperplasia is treated with mineralocorticoid antagonists. Biochemical cure following adrenalectomy occurs in 99% of patients, and hemodynamic improvement is seen in over 90%, prompting a reduction in quantity of anti-hypertensive medications in most patients. End-organ damage secondary to hypertension and excess aldosterone is significantly improved by both surgical and medical treatment, as manifested by decreased left ventricular hypertrophy, arterial stiffness, and proteinuria, highlighting the importance of proper diagnosis and treatment of primary hyperaldosteronism. Although numerous independent predictors of resolution of hypertension after adrenalectomy for unilateral adenomas have been described, the Aldosteronoma Resolution Score is a validated multifactorial model convenient for use in daily clinical practice.

Abstract
UNLABELLED Adrenal venous sampling (AVS) is a challenging technical procedure and few patients had AVS procedure twice. AIM To evaluate the reproducibility of the AVS, why AVS were repeated and the conclusions drawn from them. PATIENTS AND METHODS From 1997-2012, 12 patients underwent two AVS. A cortisol level in the adrenal vein greater than or equal to 1.1 to inferior vena cava defined a successful catheterization and a lateralization of secretion corresponded to an aldosterone-to-cortisol vein ratio greater than or equal to 2 between the one side to another. RESULTS The same side of lateralization of secretion was found in 75% of them. The second AVS were due to technical failure (n=4), unproven lateralization (n=2), a lateralization opposite to the main nodule and ipsilateral to hyperplasia (n=4) on first AVS. For two patients, as the CT was normal, AVS was required again. The second AVS was successful in all patients, including those with an initial technical failure but only patient with technical failure underwent surgery, as BP and kaliemia were controlled. Lateralization on the side of hyperplasia or opposite to the biggest nodule was confirmed in two of four cases. CONCLUSION When AVS is unsuccessful for technical reasons, it is worth doing it again but after being sure that surgery is still possibly indicated.
