    KCNJ5 Somatic Mutation Is a Predictor of Hypertension Remission After Adrenalectomy for Unilateral Primary Aldosteronism
    (2019) VILELA, Leticia A. P.; RASSI-CRUZ, Marcela; GUIMARAES, Augusto G.; MOISES, Caio C. S.; FREITAS, Thais C.; ALENCAR, Natalia P.; PETENUCI, Janaina; GOLDBAUM, Tatiana S.; MACIEL, Ana Alice W.; PEREIRA, Maria Adelaide A.; V, Giovanio Silva; PIO-ABREU, Andrea; ZERBINI, Maria Claudia N.; CAVALCANTE, Aline C. B. S.; CARNEVALE, Francisco C.; PILAN, Bruna; YAMAUCHI, Fernando; SROUGI, Vitor; TANNO, Fabio Y.; CHAMBO, Jose L.; LATRONICO, Ana Claudia; MENDONCA, Berenice B.; V, Maria Candida B. Fragoso; BORTOLOTTO, Luiz A.; DRAGER, Luciano F.; ALMEIDA, Madson Q.
    Context: Primary aldosteronism (PA) is the most common cause of endocrine hypertension (HT). HT remission (defined as blood pressure <140/90 mm Hg without antihypertensive drugs) has been reported in approximately 50% of patients with unilateral PA after adrenalectomy. HT duration and severity are predictors of blood pressure response, but the prognostic role of somatic KCNJ5 mutations is unclear. Objective: To determine clinical and molecular features associated with HT remission after adrenalectomy in patients with unilateral PA. Methods: We retrospectively evaluated 100 patients with PA (60 women; median age at diagnosis 48 years with a median follow-up of 26 months). Anatomopathological analysis revealed 90 aldosterone-producing adenomas, 1 carcinoma, and 9 unilateral adrenal hyperplasias. All patients had biochemical cure after unilateral adrenalectomy. KCNJ5 gene was sequenced in 76 cases. Results: KCNJ5 mutations were identified in 33 of 76 (43.4%) tumors: p.Gly151Arg (n = 17), p.Leu168Arg (n = 15), and p.GIu145GIn (n = 1). HT remission was reported in 37 of 100 (37%) patients. Among patients with HT remission, 73% were women (P = 0.04), 48.6% used more than three antihypertensive medications (P= 0.0001), and 64.9% had HT duration <10 years (P= 0.0015) compared with those without HT remission. Somatic KCNJ5 mutations were associated with female sex (P = 0.004), larger nodules (P = 0.001), and HT remission (P = 0.0001). In multivariate analysis, only a somatic KCNJ5 mutation was an independent predictor of HT remission after adrenalectomy (P = 0.004). Conclusion: The presence of a KCNJ5 somatic mutation is an independent predictor of HT remission after unilateral adrenalectomy in patients with unilateral PA.

    Genetic and clinical aspects of paediatric pheochromocytomas and paragangliomas
    (2021) PETENUCI, Janaina; GUIMARAES, Augusto G.; FAGUNDES, Gustavo F. C.; BENEDETTI, Anna Flavia F.; AFONSO, Ana Caroline F.; PEREIRA, Maria Adelaide A.; ZERBINI, Maria Claudia N.; SIQUEIRA, Sheila; YAMAUCHI, Fernando; SOARES, Silvia C.; SROUGI, Victor; TANNO, Fabio Y.; CHAMBO, Jose L.; I, Roberto Lopes; DENES, Francisco T.; HOFF, Ana O.; LATRONICO, Ana Claudia; MENDONCA, Berenice B.; V, Maria Candida B. Fragoso; ALMEIDA, Madson Q.
    Objective Few and conflicting reports have characterized the genetics of paediatric pheochromocytomas and paragangliomas (PPGLs). This study aimed to investigate the clinical and genetic features of Brazilian children with PPGL. Patients and Methods This study included 25 children (52% girls) with PPGL. The median age at diagnosis was 15 years (4-19). The median time of follow-up was 145 months. The genetic investigation was performed by Sanger DNA sequencing, multiplex ligation-dependent probe amplification and/or target next-generation sequencing panel. Results Of the 25 children with PPGL, 11 (44%), 4 (16%), 2 (8%), 1 (4%) and 7 (28%) had germline VHL pathogenic variants, SDHB, SDHD, RET and negative genetic investigation, respectively. Children with germline VHL missense pathogenic variants were younger than those with SDHB or SDHD genetic defects [median (range), 12 (4-16) vs. 15.5 (14-19) years; P = .027]. Moreover, 10 of 11 cases with VHL pathogenic variants had bilateral pheochromocytoma (six asynchronous and four synchronous). All children with germline SDHB pathogenic variants presented with abdominal paraganglioma (one of them malignant). The two cases with SDHD pathogenic variants presented with head and neck paraganglioma. Among the cases without a genetic diagnosis, 6 and 2 had pheochromocytoma and paraganglioma, respectively. Furthermore, metastatic PPGL was diagnosed in four (16%) of 25 PPGL. Conclusions Most of the paediatric PPGL were hereditary and multifocal. The majority of the affected genes belong to pseudohypoxic cluster 1, with VHL being the most frequently mutated. Therefore, our findings impact surgical management and surveillance of children with PPGL.

    International Histopathology Consensus for Unilateral Primary Aldosteronism
    (2021) WILLIAMS, Tracy Ann; GOMEZ-SANCHEZ, Celso E.; RAINEY, William E.; GIORDANO, Thomas J.; LAM, Alfred K.; MARKER, Alison; METE, Ozgur; YAMAZAKI, Yuto; ZERBINI, Maria Claudia Nogueira; BEUSCHLEIN, Felix; SATOH, Fumitoshi; BURRELLO, Jacopo; SCHNEIDER, Holger; LENDERS, Jacques W. M.; MULATERO, Paolo; CASTELLANO, Isabella; KNOSEL, Thomas; PAPOTTI, Mauro; SAEGER, Wolfgang; SASANO, Hironobu; REINCKE, Martin
    T Objective: Develop a consensus for the nomenclature and definition of adrenal histopathologic features in unilateral primary aldosteronism (PA). Context: Unilateral PA is the most common surgically treated form of hypertension. Morphologic examination combined with CYP11B2 (aldosterone synthase) immunostaining reveals diverse histopathologic features of lesions in the resected adrenals. Patients and methods: Surgically removed adrenals (n = 37) from 90 patients operated from 2015 to 2018 in Munich, Germany, were selected to represent the broad histologic spectrum of unilateral PA. Five pathologists (Group 1 from Germany, Italy, and Japan) evaluated the histopathology of hematoxylin-eosin (HE) and CYP11B2 immunostained sections, and a consensus was established to define the identifiable features. The consensus was subsequently used by 6 additional pathologists (Group 2 from Australia, Brazil, Canada, Japan, United Kingdom, United States) for the assessment of all adrenals with disagreement for histopathologic diagnoses among group 1 pathologists. Results: Consensus was achieved to define histopathologic features associated with PA. Use of CYP11B2 immunostaining resulted in a change of the original HE morphology-driven diagnosis in 5 (14%) of 37 cases. Using the consensus criteria, group 2 pathologists agreed for the evaluation of 11 of the 12 cases of disagreement among group 1 pathologists. Conclusion: The HISTALDO (histopathology of primary aldosteronism) consensus is useful to standardize nomenclature and achieve consistency among pathologists for the histopathologic diagnosis of unilateral PA. CYP11B2 immunohistochemistry should be incorporated into the routine clinical diagnostic workup to localize the likely source of aldosterone production.

    Development and internal validation of an adrenal cortical carcinoma prognostic score for predicting the risk of metastasis and local recurrence
    (2013) FREIRE, Daniel Soares; SIQUEIRA, Sheila Aparecida Coelho; ZERBINI, Maria Claudia Nogueira; WAJCHENBERG, Bernardo Leo; CORREA-GIANNELLA, Maria Lucia; LUCON, Antonio Marmo; PEREIRA, Maria Adelaide Albergaria
    Objective To develop and internally validate a prognostic score to predict the risk of metastases or recurrence in patients with adrenal cortical carcinomas (ACC). Design Clinical, laboratory and pathological data from 129 ACC patients, treated in a tertiary centre, were retrospectively reviewed. Results Using a multivariate binary logistic regression analysis, we developed a prognostic score with five covariates: a functional pattern other than isolated hyperandrogenism, a tumour size >75cm, a primary tumour classified as T3/T4, the presence of microscopic venous invasion and a mitotic index >5/50 high-power fields. The prognostic score was calibrated according to the Hosmer-Lemeshow goodness-of-fit test (P=09329) and exhibited excellent overall performance (Brier score=00738). Finally, the discriminatory ability of the model, determined by the area under the ROC curve (A(ROC)), was near perfect (A(ROC), 09611; 95% CI, 092676-099552). The prediction model was internally validated with 200 bootstrap resamples and achieved excellent performance for estimating the risk of metastasis and recurrence in eight additional patients with apparently localized disease at diagnosis. Conclusion We developed and internally validated a prognostic score based on the clinicopathological data that are readily available to any attending physician. Our model can be used to accurately estimate the risk of unfavourable outcomes in ACC patients. This score could be beneficial for both patient counselling and the identification of patients in whom adjuvant mitotane is justified.

    Expression of SOAT1 in Adrenocortical Carcinoma and Response to Mitotane Monotherapy: An ENSAT Multicenter Study
    (2020) WEIGAND, Isabel; ALTIERI, Barbara; LACOMBE, Amanda M. F.; BASILE, Vittoria; KIRCHER, Stefan; LANDWEHR, Laura-Sophie; SCHREINER, Jochen; ZERBINI, Maria C. N.; RONCHI, Cristina L.; MEGERLE, Felix; BERRUTI, Alfredo; CANU, Letizia; VOLANTE, Marco; PAIVA, Isabel; CASA, Silvia Della; SBIERA, Silviu; FASSNACHT, Martin; V, Maria Candida B. Fragoso; TERZOLO, Massimo; KROISS, Matthias
    Context: Objective response rate to mitotane in advanced adrenocortical carcinoma (ACC) is approximately 20%, and adverse drug effects are frequent. To date, there is no marker established that predicts treatment response. Mitotane has been shown to inhibit sterol-O-acyl transferase 1 (SOAT1), which leads to endoplasmic reticulum stress and cell death in ACC cells. Objective: To investigate SOAT1 protein expression as a marker of treatment response to mitotane. Patients: A total of 231 ACC patients treated with single-agent mitotane as adjuvant (n = 158) or advanced disease therapy (n = 73) from 12 ENSAT centers were included. SOAT1 protein expression was determined by immunohistochemistry on formalin-fixed paraffin-embedded specimens. Setting: Retrospective study at 12 ACC referral centers. Main outcome measure: Recurrence-free survival (RFS), progression-free survival (PFS), and disease-specific survival (DSS). Results: Sixty-one of 135 patients (45%) with adjuvant mitotane treatment had recurrences and 45/68 patients (66%) with mitotane treatment for advanced disease had progressive disease. After multivariate adjustment for sex, age, hormone secretion, tumor stage, and Ki67 index, RFS (hazard ratio [HR] = 1.07; 95% confidence interval [CI], 0.61-1.85; P = 0.82), and DSS (HR = 1.30; 95% CI, 0.58-2.93; P = 0.53) in adjuvantly treated ACC patients did not differ significantly between tumors with high and low SOAT1 expression. Similarly, in the advanced stage setting, PFS (HR = 1.34; 95% CI, 0.63-2.84; P = 0.45) and DSS (HR = 0.72; 95% CI, 0.31-1.70; P = 0.45) were comparable and response rates not significantly different. Conclusions: SOAT1 expression was not correlated with clinical endpoints RFS, PFS, and DSS in ACC patients with mitotane monotherapy. Other factors appear to be relevant for mitotane treatment response and ACC patient survival.

    Phosphodiesterase 2A and 3B variants are associated with primary aldosteronism
    (2021) RASSI-CRUZ, Marcela; MARIA, Andrea G.; FAUCZ, Fabio R.; LONDON, Edra; VILELA, Leticia A. P.; SANTANA, Lucas S.; BENEDETTI, Anna Flavia F.; GOLDBAUM, Tatiana S.; TANNO, Fabio Y.; SROUGI, Vitor; CHAMBO, Jose L.; PEREIRA, Maria Adelaide A.; CAVALCANTE, Aline C. B. S.; CARNEVALE, Francisco C.; PILAN, Bruna; BORTOLOTTO, Luiz A.; DRAGER, Luciano F.; LERARIO, Antonio M.; LATRONICO, Ana Claudia; V, Maria Candida B. Fragoso; MENDONCA, Berenice B.; ZERBINI, Maria Claudia N.; STRATAKIS, Constantine A.; ALMEIDA, Madson Q.
    Familial primary aldosteronism (PA) is rare and mostly diagnosed in early-onset hypertension (HT). However, 'sporadic' bilateral adrenal hyperplasia (BAH) is the most frequent cause of PA and remains without genetic etiology in most cases. Our aim was to investigate new genetic defects associated with BAH and PA. We performed whole-exome sequencing (paired blood and adrenal tissue) in six patients with PA caused by BAH that underwent unilateral adrenalectomy. Additionally, we conducted functional studies in adrenal hyperplastic tissue and transfected cells to confirm the pathogenicity of the identified genetic variants. Rare germline variants in phosphodiesterase 2A (PDE2A) and 3B (PDE3B) genes were identified in three patients. The PDE2A heterozygous variant (p.Ile629Val) was identified in a patient with BAH and early-onset HT at 13 years of age. Two PDE3B heterozygous variants (p.Arg217Gln and p.Gly392Val) were identified in patients with BAH and HT diagnosed at 18 and 33 years of age, respectively. A strong PDE2A staining was found in all cases of BAH in zona glomerulosa and/or micronodules (that were also positive for CYP11B2). PKA activity in frozen tissue was significantly higher in BAH from patients harboring PDE2A and PDE3B variants. PDE2A and PDE3B variants significantly reduced protein expression in mutant transfected cells compared to WT. Interestingly, PDE2A and PDE3B variants increased SGK1 and SCNN1G/ENaCg at mRNA or protein levels. In conclusion, PDE2A and PDE3B variants were associated with PA caused by BAH. These novel genetic findings expand the spectrum of gene tic etiologies of PA.

    A New Insight into the Surgical Treatment of Primary Macronodular Adrenal Hyperplasia
    (2020) TANNO, Fabio Yoshiaki; SROUGI, Victor; ALMEIDA, Madson Q.; YAMAUCHI, Fernando Ide; COELHO, Fernando Morbeck Almeida; NISHI, Mirian Yumie; ZERBINI, Maria Claudia Nogueira; SOARES, Iracy Silvia Correa; PEREIRA, Maria Adelaide Albergaria; CHARCHAR, Helaine Laiz Silva; LACOMBE, Amanda Meneses Ferreira; BRONDANI, Vania Balderrama; SROUGI, Miguel; NAHAS, Willian Carlos; MENDONCA, Berenice B.; CHAMBO, Jose Luis; FRAGOSO, Maria Candida Barisson Villares
    Purpose: This prospective study presents the results of a new approach in the treatment of primary macronodular adrenal hyperplasia (PMAII), with simultaneous total adrenalectomy of the larger adrenal gland and partial adrenalectomy of the contralateral adrenal gland (adrenal-sparing surgery). Materials and Methods: We performed a prospective study including 17 patients with PMAH treated surgically with adrenal-sparing surgery in a tertiary referral hospital, with a median follow-up of 41 months. Clinical, hormonal, and genetic parameters were evaluated before surgery and during follow-up. All patients had at least 1 radiological examination before and after the procedure. Results: Among the 17 patients, all but 1 patient had complete hypercortisolism control, and 12 recovered normal adrenal function after surgery. Significant improvement in clinical parameters was observed: weight loss (P = .004); reduction of both systolic (P = .001) and diastolic (P = .001) blood pressure; and reduction in the number of antihypertensive drugs (P < .001). Intra-, peri-, and postoperative complications were not observed. Conclusion: Adrenal-sparing surgery is a safe and feasible procedure to treat patients with PMAH, providing a substantial chance of hypercortisolism control without the disadvantages of lifetime corticosteroid replacement.

    DAX1 Overexpression in Pediatric Adrenocortical Tumors: A Synergic Role with SF1 in Tumorigenesis
    (2015) SOUSA, G. R. V. de; SOARES, I. C.; FARIA, A. M.; DOMINGUES, V. B.; WAKAMATSU, A.; LERARIO, A. M.; ALVES, V. A. F.; ZERBINI, M. C. N.; MENDONCA, B. B.; FRAGOSO, M. C. B. V.; LATRONICO, A. C.; ALMEIDA, M. Q.
    DAX1 transcription factor is a key determinant of adrenogonadal development, acting as a repressor of SF1 targets in steroidogenesis. It was recently demonstrated that DAX1 regulates pluripotency and differentiation in murine embryonic stem cells. In this study, we investigated DAX1 expression in adrenocortical tumors (ACTs) and correlated it with SF1 expression and clinical parameters. DAX1 and SF1 protein expression were assessed in 104 ACTs from 34 children (25 clinically benign and 9 malignant) and 70 adults (40 adenomas and 30 carcinomas). DAX1 gene expression was studied in 49 ACTs by quantitative real-time PCR. A strong DAX1 protein expression was demonstrated in 74% (25 out of 34) and 24% (17 out of 70) of pediatric and adult ACTs, respectively ((2)=10.1, p=0.002). In the pediatric group, ACTs with a strong DAX1 expression were diagnosed at earlier ages than ACTs with weak expression [median 1.2 (range, 0.5-4.5) vs. 2.2 (0.9-9.4), p=0.038]. DAX1 expression was not associated with functional status in ACTs. Interestingly, a positive correlation was observed between DAX1 and SF1 protein expression in both pediatric and adult ACTs (r=0.55 for each group separately; p<0.0001). In addition, DAX1 gene expression was significantly correlated with SF1 gene expression (p<0.0001, r=0.54). In conclusion, DAX1 strong protein expression was more frequent in pediatric than in adult ACTs. Additionally, DAX1 and SF1 expression positively correlated in ACTs, suggesting that these transcription factors might cooperate in adrenocortical tumorigenesis.
