Abstract
Introduction Aldosterone-producing adenoma (APA) is the most common cause of endocrine-related hypertension but surgery is not always feasible. Current medical interventions are associated with significant side effects and poor patient compliance. New APA animal models that replicate basic characteristics of APA and give physical and biochemical feedback are needed to test new non-surgical treatment methods, such as image-guided thermal ablation. Methods A model of APA was developed in nude mice using HAC15 cells, a human adrenal carcinoma cell line. Tumor growth, aldosterone production, and sensitivity to angiotensin II were characterized in the model. The utility of the model was validated via treatment with microwave ablation and characterization of the resulting physical and biochemical changes in the tumor. Results The APA model showed rapid and relatively homogeneous growth. The tumors produced aldosterone and steroid precursors in response to angiotensin II challenge, and plasma aldosterone levels were significantly higher in tumor bearing mice two hours after challenge verses non-tumor bearing mice. The model was useful for testing microwave ablation therapy, reducing aldosterone production by 80% in treated mice. Conclusion The HAC15 model is a useful tumor model to study and develop localized treatment methods for APA.

The Therapeutic Intensity Score as Predictor of Clinical Outcomes after Total and Partial Adrenalectomy for Unilateral Primary Aldosteronism: Results of a Multicentric Series. J Clin Med 2023; 12:jcm12030997. [PMID: 36769646 PMCID: PMC9917842 DOI: 10.3390/jcm12030997] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 01/11/2023] [Accepted: 01/13/2023] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND To evaluate the ability of therapeutic intensity score (TIS) in predicting the clinical outcomes of partial (PA) and total adrenalectomy (TA) for UPA. METHODS Between 2011 and 2022, a four-center adrenalectomy dataset was queried for "unilateral adrenal mass" and "UPA" (n = 90). Preoperative TIS of each antihypertensive medication were individually calculated and merged to create a single, cumulative variable. Probability of complete clinical, partial, and absent pooled success rates according to TIS were assessed for the overall cohort by Kaplan-Meier. Cox analyses were used to identify predictors of complete clinical and partial/absent success, respectively. For all analyses, a two-sided p < 0.05 was considered significant. RESULTS At a median follow-up of 42 months (IQR 27-54) complete partial, and absent clinical success were observed in 60%, 17.7%, and 22.3%, respectively. On Kaplan-Meier analysis, TIS < 1 predicted higher complete success rates (p < 0.001), while TIS ≥ 1 was predictor of either partial and absent clinical success (p = 0.008). On multivariable analysis, TIS < 1 (HR 0.25; 95% CI 0.11-0.57; p = 0.001) and adenoma size (HR 1.11; 95% CI 1-1.23; p = 0.0049) were independent predictors of complete clinical success, while TIS ≥ 1 (HR 2.84; 95% CI 1.32-6.1; p = 0.007) was the only independent predictor of absent clinical success. CONCLUSIONS TIS score and adenoma size may help to identify patients who are likely to be at risk of persistent hypertension after surgery.

Abstract
CONTEXT There are inconsistent results and insufficient evidence as to whether an association exists between the size and aldosterone-producing ability of aldosterone-producing adenomas. OBJECTIVE We further investigated this possible association retrospectively. METHODS A total of 142 cases of primary aldosteronism diagnosed as unilateral by adrenal venous sampling at 2 referral centers between 2009 and 2019 were included. We classified these individuals into small and large tumor groups using a diameter of 14 mm as a cutoff. This size was the median diameter of the tumor on the affected side of the adrenal gland. We compared plasma aldosterone concentration (PAC), plasma renin activity (PRA), PAC to PRA ratio, PAC from a saline infusion test (SIT), urinary aldosterone secretion (uAld), and serum potassium as indices of aldosterone-producing ability between the 2 groups. In some cases, we conducted histopathological evaluations and detection of the KCNJ5 mutation. RESULTS PAC, PAC to PRA ratio, PAC from SIT, and uAld were higher and serum potassium was lower in the large tumor group. PAC, PAC from SIT, uAld, and serum potassium significantly correlated with tumor diameter. PRA was not associated with tumor diameter. Clear cell-dominant cases were more common in the large tumor group, while cases showing a strong expression of CYP11B2 were not significantly different between the groups. KCNJ5 mutations tended to be more common in the large tumor group. CONCLUSION The higher aldosterone-producing ability in larger adenomas can be used to infer the responsible lesion and disease type.

Association of preserved vegetable consumption and prevalence of colorectal polyps: results from the Lanxi Pre-colorectal Cancer Cohort (LP3C). Eur J Nutr 2021; 61:1273-1284. [PMID: 34750639 DOI: 10.1007/s00394-021-02719-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Accepted: 10/18/2021] [Indexed: 01/06/2023]
Abstract
PURPOSE Although fresh vegetable consumption has been linked with a lower risk of colorectal polyps, a precursor lesion for colorectal cancer (CRC), the association between preserved vegetable consumption and colorectal polyps is unknown. We aimed to assess the association of preserved vegetable intake with the prevalence of colorectal polyps with the consideration of subsites, sizes and multiplicity of polyps. METHODS We analyzed the cross-sectional data from 40-80 years Chinese at a high risk of CRC from the Lanxi Pre-colorectal Cancer Cohort (LP3C) baseline survey, which was conducted between March 2018 and December 2019. Dietary information was obtained via a validated food frequency questionnaire. Multivariate logistic regression was employed to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of preserved vegetable consumption and the prevalence of colorectal polyps. RESULTS Of 6783 eligible participants in 2018-2019 survey of LP3C, 2064 prevalent colorectal polyp cases were identified. In the multivariable-adjusted model, preserved vegetable consumption was positively associated with the prevalence of colorectal polyps (OR for fourth vs. first quartile: 1.18; 95% CI 1.01-1.36; P trend = 0.02). The similar association was also detected for small polyps [ORQ4 vs Q1 (95% CI): 1.17 (1.00-1.37); P trend = 0.03]. The similar trend was detected for multiple polyps [OR Q4 vs Q1 (95% CI):1.27 (0.98-1.64); P trend = 0.04], proximal colon polyps [ORQ4 vs Q1 (95% CI): 1.12 (0.90-1.38); P trend = 0.07], and single polyp [ORQ4 vs Q1 (95% CI) for 1.15 (0.98-1.35); P trend = 0.06]. No significant association was observed for distal colon [ORQ4 vs Q1 (95% CI) 1.19 (0.98-1.45); P trend = 0.09]. Replacing one serving per day of preserved vegetables with fresh vegetables was related to 20%, 23%, and 37% lower prevalence of overall, small, and multiple polyps, respectively. CONCLUSIONS Preserved vegetable consumption was associated with a higher prevalence of colorectal polyps in a Chinese population at a high risk of CRC. Replacing preserved vegetables with fresh vegetables may be conducive to lower prevalent colorectal polyps.

Abstract
Context Aldosterone-producing adenomas are a curable subtype of primary aldosteronism (PA); however, hypertension persists in some patients after adrenalectomy. Objective To identify factors associated with, and develop prediction models for, blood pressure (BP) normalization or improvement after adrenalectomy. Design Retrospective analysis of patients treated between 2006 and 2018, with a 6-month follow-up. Setting A nationwide, 29-center Japanese registry encompassing 15 university hospitals and 14 city hospitals. Patients We categorized 574 participants in the Japan Primary Aldosteronism Study, who were diagnosed with PA and underwent adrenalectomy, as BP normalized or improved, on the basis of their presentations at 6 months postsurgery. Main Outcome Measure The rate of complete, partial, and absent clinical success. Predictive factors related to BP outcomes after PA surgery were also evaluated. Results Complete clinical success was achieved in 32.6% and partial clinical success was achieved in 53.0% of the patients at 6 months postsurgery. The following five variables were independent predictors for BP normalization: ≤7 years of hypertension, body mass index ≤25 kg/m2, no more than one antihypertensive medication, absence of medical history of diabetes, and female sex. The area under the receiver operator characteristic curve was 0.797 in the BP normalization model. Conclusion We established models that predicted postoperative BP normalization in patients with PA. These should be useful for shared decision-making regarding adrenalectomy for PA.

Abstract
OBJECTIVE To describe the challenging case of a 59-year-old male with a deoxycorticosterone (DOC)-producing adrenal adenoma concomitant with an aldosterone-producing microadenoma. METHODS We measured the patient's aldosterone and progesterone levels during adrenal venous sampling (AVS). The steroidogenic enzyme expression was studied with in situ hybridization (ISH). Steroids profiles were determined in the peripheral serum obtained before and after the operation, as well as in the main adrenal tumor. RESULTS The patient was diagnosed with primary aldosteronism (PA) based on typical clinical findings. He had an adrenal tumor located at the lower pole of the left adrenal gland. The aldosterone concentration in the adrenal vein proximal to the adrenal tumor was higher than that of the ipsilateral adrenal vein distal to the tumor during the AVS. Progesterone was only elevated in the adrenal vein proximal to the tumor, suggesting that the tumor produced steroids other than aldosterone. The postoperative findings revealed that the main tumor was accompanied by 2 microadenomas. The main adrenal tumor was diagnosed as a DOC-producing adenoma, and one of the microadenomas was diagnosed as aldosterone-producing based on the ISH and the determination of the steroid profiles. CONCLUSIONS Concomitant PA masked the key findings of a DOC-producing tumor; the suppression of aldosterone in this patient. Multiple sampling in the adrenal vein considering the location of the adrenal tumor provided a clue to the diagnosis. Progesterone measurement during AVS is easy and may be useful in diagnosing rare adrenal tumors that produce intermediate products in adrenal steroid biosynthesis.

Abstract
BACKGROUND The aim of this study was to investigate the factors associated with resolution of hypertension after adrenalectomy in patients with primary aldosteronism. A secondary aim was to describe our use of the contralateral ratio in adrenal venous sampling (AVS) in the setting of suboptimal successful cannulation rates. METHODS A retrospective review of patients who underwent AVS followed by unilateral adrenalectomy for primary aldosteronism was performed. RESULTS Complete resolution of hypertension and hypokalemia was seen in 17 of 40 patients (42.5%), while a clinical improvement in hypertension was seen in 38 of 40 (95%). Shorter duration of hypertension, mean aldosteronoma resolution score (ARS), and a high ARS of 3 to 5 were associated with resolution of hypertension after adrenalectomy (P=0.02, P=0.02, and P=0.004, respectively). Of the individual components of ARS, only a duration of hypertension of ≤6 years was associated with resolution of hypertension after adrenalectomy (P=0.03). CONCLUSION A shorter duration of hypertension was significantly associated with resolution of hypertension after adrenalectomy in patients with primary aldosteronism.

Abstract
BACKGROUND/PURPOSE Even with the increasing recognition of primary aldosteronism (PA) as a cause of refractory hypertension and an issue of public health, the consensus of its optimal surgical or medical treatment in Taiwan has not been reached. Our objective was to develop a clinical practice guideline that is feasible for real-world management of PA patients in Taiwan. METHODS The Taiwan Society of Aldosteronism (TSA) Task Force recognized the above-mentioned issues and reached this Taiwan PA consensus at its inaugural meeting, in order to provide updated information of internationally acceptable standards, and also to incorporate our local disease characteristics and constraints into PA management. RESULTS In patients with lateralized PA, including aldosterone producing adenoma (APA), laparoscopic adrenalectomy is the 'gold standard' of treatment. Mini-laparoscopic and laparoendoscopic single-site approaches are feasible only in highly experienced surgeons. Patients with bilateral adrenal hyperplasia or those not suitable for surgery should be treated by mineralocorticoid receptor antagonists. The outcome data of PA patient management from the literature, especially from PA patients in Taiwan, are reviewed. Mental health screening is helpful in early detection and management of psychopathology among PA patients. CONCLUSION We hope this consensus will provide a guideline to help medical professionals to manage PA patients in Taiwan to achieve a better quality of care.

Abstract
BACKGROUND Primary hyperaldosteronism is a common cause of hypertension, with significant cardiovascular, renal, and metabolic sequelae. Delayed diagnosis of primary hyperaldosteronism can lead to severe disease and lower cure rates after adrenalectomy. This study investigated the presentation and outcomes of patients who had primary hyperaldosteronism diagnosed after incidental discovery of an adrenal mass. METHODS A retrospective cohort study investigated patients receiving adrenalectomy for primary hyperaldosteronism at the authors' institution from 2001 to 2014. Patients were classified as nonincidental if the aldosteronoma was identified on imaging performed for a hypertension or hypokalemia workup or after a biochemical diagnosis or as incidental if the aldosteronoma was identified on imaging performed for any other reason. Nonincidental and incidental patients were compared in terms of patient demographics, clinical history, preoperative test results, surgical pathology findings, and postoperative course. RESULTS The study included 210 patients, 17 (8.1 %) of whom were incidental. At the time of surgical evaluation, 88 % of the incidental patients met the criteria for primary hyperaldosteronism screening based on hypokalemia or the degree of hypertension. The incidental patients were younger than the nonincidental patients, but the two groups were otherwise demographically and clinically similar. The incidental patients had larger aldosteronomas than the nonincidental patients. The nonincidental and incidental patients had similar rates of postoperative cure and failure. CONCLUSIONS Nonincidental and incidental patients have comparable disease severity before surgical evaluation and similar rates of postoperative cure. Increased adherence to guidelines for screening of primary hyperaldosteronism will lead to a more timely diagnosis for all patients and a higher potential for surgical cure.

Abstract
OBJECTIVE Unilateral adrenalectomy is the first-line treatment for aldosterone-producing adenomas (APA). Hyperkalemia after adrenalectomy because of contralateral zona glomerulosa insufficiency has been reported. We investigated clinical risk factors to predict postoperative hyperkalemia in patients with APA undergoing adrenalectomy. DESIGN AND METHODS This study was conducted by retrospectively reviewing medical records from 2000 to 2012 at Seoul National University Hospital and two other tertiary centers. Data from 124 patients who underwent adrenalectomy were included. Hyperkalemia was defined as serum potassium >5.5 mmol/l. Clinical preoperative risk factors included age, blood pressure, plasma renin activity (PRA), plasma aldosterone concentration (PAC), serum potassium, serum creatinine, glomerular filtration rate (GFR), the mass size on pathology, and mineralocorticoid receptor (MR) antagonist use. RESULTS Out of 124 patients, 13 (10.5%) developed postoperative hyperkalemia. The incidences of transient and persistent hyperkalemia were 3.2 and 7.3% respectively. Preoperative PRA and PAC were not significantly different in postoperative hyperkalemic patients compared with normokalemic patients. Patients with persistent hyperkalemia were older, had a longer duration of hypertension, larger mass size on pathology, and lower GFR (all P<0.05). The incidence of postoperative hyperkalemia was not different between MR antagonist users and non-users. CONCLUSION Older age (≥53 years), longer duration of hypertension (≥9.5 years), larger mass size on pathology (≥1.95 cm), and impaired preoperative renal function (GFR <58.2 ml/min) were associated with prolonged postoperative hyperkalemia in patients with APA. MR antagonist use did not prevent postoperative hyperkalemia.

Abstract
CONTEXT Adrenal vein sampling (AVS) is the only reliable means to distinguish between aldosterone-producing adenoma and bilateral adrenal hyperplasia, the two most common subtypes of primary aldosteronism (PA). AVS protocols are not standardized and vary widely between centers. OBJECTIVE The objective of the study was to retrospectively investigate whether the presence of contralateral adrenal (CL) suppression of aldosterone secretion was associated with improved postoperative outcomes in patients who underwent unilateral adrenalectomy for PA. SETTING The study was carried out in eight different referral centers in Italy, Germany, and Japan. PATIENTS From 585 consecutive AVS in patients with confirmed PA, 234 procedures met the inclusion criteria and were used for the subsequent analyses. RESULTS Overall, 82% of patients displayed contralateral suppression. This percentage was significantly higher in ACTH stimulated compared with basal procedures (90% vs 77%). The CL ratio was inversely correlated with the aldosterone level at diagnosis and, among AVS parameters, with the lateralization index (P = .02 and P = .01, respectively). The absence of contralateral suppression was not associated with a lower rate of response to adrenalectomy in terms of both clinical and biochemical parameters, and patients with CL suppression underwent a significantly larger reduction in the aldosterone levels after adrenalectomy. CONCLUSIONS For patients with lateralizing indices of greater than 4 (which comprised the great majority of subjects in this study), CL suppression should not be required to refer patients to adrenalectomy because it is not associated with a larger blood pressure reduction after surgery and might exclude patients from curative surgery.

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

Abstract
BACKGROUND Primary aldosteronism caused by an aldosterone producing adrenal tumor/aldosteronoma (APA), is a potentially curable form of hypertension, via unilateral adrenalectomy. Resolution of hypertension (HTN) is not as prevalent after tumor resection, as are the normalization of aldosterone secretion, hypokalemia, and other metabolic abnormalities. Here, we review the immediate and long-term medical outcomes of laparoscopic adrenalectomy in patients with an APA, and attempt to identify any distinctive sex differences in the management of resistant HTN. METHODS We performed a retrospective review of the prospective adrenal database at the University of Wisconsin between January 2001 and October 2010. Of the 165 adrenalectomies performed, 32 were for the resection of an APA. Patients were grouped according to their postoperative HTN status. Those patients with normal blood pressure (≤120/80 mm Hg) and on no antihypertensive medication (CURE) were compared with those who continued to require medication for blood pressure control (HTN). We evaluated sex, age, body mass index, tumor size, duration of time with high blood pressure, and the differences in systolic and diastolic blood pressure following adrenalectomy. Statistical analysis was performed using Student's t-test. Statistical significance was defined as a P value of <0.05. RESULTS We identified 32 patients with an APA based on biochemical and radiographic studies, two patients were excluded, due to missing data. There were 19 males (63%) and 11 (37%) females, with a mean age was 48.3 ± 2.1 y, and mean tumor size was 24 ± 3 mm. Postoperatively, patients required significantly fewer antihypertensive medications (1.5 ± 0.2 versus 3.3 ± 0.3, P < 0.001). Nine patients (31%) had complete resolution of their HTN, requiring no postoperative antihypertensive medication. The only significant difference between the sexes, was a lower body mass index in women (27.6 ± 1.7 versus 33.4 ± 2.1 kg/m(2), P = 0.04). Ninety percent of the cohort had at least a 20 mm Hg decline in their systolic blood pressure postoperatively, placing them in the prehypertensive or normal blood pressure categories. Sixty-six percent of the CURE patients required at least 6 mo for resolution of their HTN. All 20 patients who presented with hypokalemia, had immediate resolution postoperatively and did not require continuance of the preoperative spironolactone or potassium supplementation. CONCLUSIONS Laparoscopic adrenalectomy for aldosterone producing adenoma results in the normalization of, or more readily manageable blood pressure in 90% of patients, within 6 mo. Metabolic disturbances are immediately corrected with tumor resection. Weight is an important contributing factor in resolving HTN.

Abstract
An increasing number of patients are being diagnosed with primary aldosteronism (PA) due to aldosterone-producing macroadenoma (APA). However, there are only limited data available on the clinical characteristics of PA that are associated with adrenal microadenoma. Of the 55 patients that were diagnosed with PA in our study, 22 patients showed a unilateral adrenal over-production of aldosterone. The histopathology of the surgically removed adrenal tissues led to six patients being diagnosed with microadenoma, and the clinical features of microadenoma, macroadenoma and idiopathic hyperaldosteronism (IHA) were studied. The expression levels of CYP11B2, CYP17, CYP21 and 3β-hydroxysteroid dehydrogenase 2 (HSD3B2) mRNA in the adrenal cortices (n=5 and 6, respectively) that remained attached to the adrenal microadenomas or macroadenomas were examined by real time-PCR and then compared to the expression levels in the adrenal cortices (n=5) of non-functioning adrenal adenomas (NF). The patients with microadenoma (n=6) had significantly higher diastolic blood pressure than the patients with macroadenoma (n=16) or IHA (n=33) (p<0.05). The systolic blood pressure, plasma aldosterone concentration, serum potassium level and renal function did not differ between the PA sub-groups. The levels of CYP11B2 and CYP17 mRNA were significantly increased in the adjacent tissues of microadenomas, as compared with macroadenomas or NF (p<0.05), whereas no significant differences in the CYP21 and HSD3B2 mRNA levels were found between the PA sub-groups. The tumor size did not influence the clinical characteristics of APA. The non-tumor portions of the microadenomas showed marked and sustained CYP11B2 mRNA expression under the suppressed renin-angiotensin system. We suggest that an increased number of microadenomas should be sampled, and the immunohistochemistry for steoridogenic enzymes should be investigated to clarify the etiology of microadenoma.

Abstract
BACKGROUND Primary aldosteronism caused by aldosterone-producing adenoma is the most common curable cause of secondary hypertension, but despite resection, many patients continue to require antihypertensive medications to control their blood pressure postoperatively. The Aldosteronoma Resolution Score is a preoperative 4-item predictive model for the complete postoperative resolution of hypertension. Our aim was to validate the accuracy of this model in predicting postoperative resolution of hypertension in Japanese patients. METHODS The records of 91 Japanese patients who underwent unilateral adrenalectomy for aldosterone-producing adenoma were surveyed retrospectively. Patients were distributed into 2 groups according to whether blood pressure was normal without antihypertensive medications at 6 months postoperatively. Clinical and biochemical data were evaluated at baseline and after the 6-month follow-up. RESULTS At 6 months, blood pressure had normalized in 45% of the patients without antihypertensive medications. Multivariate logistic regression analysis revealed that patients who had complete resolution of hypertension were significantly more likely to have been taking ≤2 antihypertensive medications preoperatively, have a duration of hypertension of <6 years, and be female. The predictive accuracy of the Aldosteronoma Resolution Score was assessed using the area under the curve of receiver operator characteristics analysis. The value of the area under the curve was 0.81. CONCLUSION Our external validation revealed that the Aldosteronoma Resolution Score developed using Western data can identify accurately Japanese individuals with aldosterone-producing adenoma who are likely to have complete resolution of hypertension after adrenalectomy.
