    Service d'endocrinologie, hôpital Haut-Lévèque, avenue Magellan, CHU de Bordeaux, 33600 Pessac, France.
    The 2017 Endocrine Society annual meeting included several communications and debates on the conservative adrenal surgery in bilateral hereditary pheochromocytomas (BHP), bilateral adrenal macronodular hyperplasia (BAMH) and primary hyperaldosteronism (PHA). The general principle is to preserve a part of the adrenal cortex to prevent the occurrence of a definitive adrenal insufficiency. In BHP, cortical sparing surgery allows more than 50% of patients to maintain normal corticotropic function at 10 years with a low recurrence rate (~ 10%). Read More

    Three cases of adrenocortical tumors mistaken for hepatocellular carcinomas/diagnostic pitfalls and differential diagnosis.
    Ann Diagn Pathol 2017 Dec 29;31:9-13. Epub 2017 May 29.
    Department of Pathology, Pusan National University Hospital and Pusan National University School of Medicine, Busan, Republic of Korea; BioMedical Research Institute, Pusan National University Hospital, Busan, Republic of Korea. Electronic address:
    Adrenocortical adenomas and carcinomas in other parenchyma are extremely rare, with few cases reported and because of the rarity of these tumors, they occasionally cause problems during diagnosis. Adrenal cortical neoplasms in liver parenchyma can be present in 3 forms, including direct invasion or adhesion to liver parenchyma, tumors arising in adrenohepatic fusion tissue or in ectopic adrenal gland tissue. We report 3 cases of adrenal cortical tumors that were misdiagnosed as hepatocellular carcinoma in the preoperative state. Read More

    A case report of hyponatremia after surgery for Conn's adenoma.

    Cardiovascular events and target organ damage in primary aldosteronism compared with essential hypertension: a systematic review and meta-analysis.
    Lancet Diabetes Endocrinol 2017 Nov 9. Epub 2017 Nov 9.
    Division of Internal Medicine and Hypertension Unit, Department of Medical Sciences, University of Turin, Turin, Italy. Electronic address:
    Background: There is conflicting evidence, relying on heterogeneous studies, as to whether aldosterone excess is responsible for an increased risk of cardiovascular and cerebrovascular complications in patients with primary aldosteronism. We aimed to assess the association between primary aldosteronism and adverse cardiac and cerebrovascular events, target organ damage, diabetes, and metabolic syndrome, compared with the association of essential hypertension and these cardiovascular and end organ events, by integrating results of previous studies.

    Methods: We did a meta-analysis of prospective and retrospective observational studies that compared patients with primary aldosteronism and essential hypertension, to analyse the association between primary aldosteronism and stroke, coronary artery disease (as co-primary endpoints), atrial fibrillation and heart failure, target organ damage, metabolic syndrome, and diabetes (as secondary endpoints).

    Calneuron 1 Increased Ca(2+) in the Endoplasmic Reticulum and Aldosterone Production in Aldosterone-Producing Adenoma.
    Hypertension 2017 Nov 6. Epub 2017 Nov 6.
    From the Department of Molecular and Internal Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima University, Japan (K.K., K.O., H.O., K.I., Y.Y., M.Y., N.H.); Division of Endocrinology, G.V. (Sonny) Montgomery VA Medical Center, Jackson, MS (C.E.G.-S., E.P.G.-S.); and University of Mississippi Medical Center, Jackson (C.E.G.-S., E.P.G.-S.).
    Aldosterone production is initiated by angiotensin II stimulation and activation of intracellular Ca(2+) signaling. In aldosterone-producing adenoma (APA) cells, the activation of intracellular Ca(2+) signaling is independent of the renin-angiotensin-aldosterone systems. The purpose of our study was to clarify molecular mechanisms of aldosterone production related to Ca(2+) signaling. Read More

    Mouse models of primary aldosteronism: from physiology to pathophysiology.
    Endocrinology 2017 Oct 23. Epub 2017 Oct 23.
    Medizinische Klinik und Poliklinik IV, Klinikum der Ludwig-Maximilians-Universität München, Munich, Germany.
    Primary aldosteronism (PA) is a common form of endocrine hypertension that is characterized by the excessive production of aldosterone relative to suppressed plasma renin levels. PA is usually caused by either a unilateral aldosterone-producing adenoma or bilateral adrenal hyperplasia. Somatic mutations have been identified in several genes that encode ion pumps and channels that may explain the aldosterone excess in over half of aldosterone-producing adenomas, whereas the pathophysiology of bilateral adrenal hyperplasia is largely unknown.

    Primary Aldosteronism: The Next Five Years.
    Horm Metab Res 2017 Oct 24. Epub 2017 Oct 24.
    Hudson Institute of Medical Research and Monash University, Clayton, Australia.
    The management of primary aldosteronism is widely varied within various published guidelines, with very little in the way of data supporting the choice of one variation over others. Current estimates of prevalence are probably accurate for aldosterone producing adenoma, but fall very short of that for bilateral adrenal hyperplasia. Discovery at the level of basic science has proven illuminating over the past 6 years in terms of unilateral disease and both somatic and germline mutations, with much less focus on the much more common bilateral disease; Attempts at harmonization have begun - for example, criteria for complete/partial/absent cure after adrenalectomy for unilateral disease; again focus on bilateral disease is muted.

    An exceedingly rare adrenal collision tumor: adrenal adenoma-metastatic breast cancer-myelolipoma.
    J Community Hosp Intern Med Perspect 2017 Oct 9;7(4):241-244. Epub 2017 Sep 9.
    Department of Medicine, Greater Baltimore Medical Center, Towson, MD, USA.
    Adrenal collision tumors (ACTs), in which distinct tumors coexist without histological intermingling in the same adrenal gland, are rare and their actual prevalence is unknown. ACTs commonly consist of adrenal cortical adenoma, myelolipoma, or metastatic malignant tumor. We report a 58-year-old woman with a past history of breast cancer, who presented with a 1 month history of fevers, chills, and abdominal fullness. Read More

    Comparison of DWIBS/T2 image fusion and PET/CT for the diagnosis of cancer in the abdominal cavity.
    Exp Ther Med 2017 Oct 22;14(4):3754-3760. Epub 2017 Aug 22.
    Department of Neurosurgery, National Hospital Organization Shimoshizu Hospital, Yotsukaido, Chiba 284-0003, Japan.
    Fusion images of diffusion-weighted whole-body imaging with background body signal suppression and T2-weighted image (DWIBS/T2) demonstrate a strong signal for malignancies, with a high contrast against the surrounding tissues, and enable anatomical analysis. In the present study, DWIBS/T2 was compared with (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) for diagnosing cancer in the abdomen. Patient records, including imaging results of examination conducted between November 2012 and May 2014, were analyzed retrospectively. Read More

    On the effect of hyperaldosteronism-inducing mutations in Na/K pumps.
    J Gen Physiol 2017 Nov 13;149(11):1009-1028. Epub 2017 Oct 13.
    Department of Cell Physiology and Molecular Biophysics, Center for Membrane Protein Research, Texas Tech University Health Sciences Center, Lubbock, TX
    Primary aldosteronism, a condition in which too much aldosterone is produced and that leads to hypertension, is often initiated by an aldosterone-producing adenoma within the zona glomerulosa of the adrenal cortex. Somatic mutations of ATP1A1, encoding the Na/K pump α1 subunit, have been found in these adenomas. It has been proposed that a passive inward current transported by several of these mutant pumps is a "gain-of-function" activity that produces membrane depolarization and concomitant increases in aldosterone production.

    Imaging of Nonmalignant Adrenal Lesions in Children.
    Radiographics 2017 Oct;37(6):1648-1664
    From the Mallinckrodt Institute of Radiology, Washington University School of Medicine, 510 S Kingshighway Blvd, Campus Box 8131-MIR, St Louis, MO 63110.
    The adrenal glands in children can be affected by a variety of benign lesions. The diagnosis of adrenal lesions can be challenging, but assessment of morphologic changes in correlation with the clinical presentation can lead to an accurate diagnosis. These lesions can be classified by their cause: congenital (eg, discoid adrenal gland, horseshoe adrenal gland, and epithelial cysts), vascular and/or traumatic (eg, adrenal hemorrhage), infectious (eg, granulomatous diseases), enzyme deficiency disorders (eg, congenital adrenal hyperplasia [CAH] and Wolman disease), benign neoplasms (eg, pheochromocytomas, ganglioneuromas, adrenal adenomas, and myelolipomas), and adrenal mass mimics (eg, extralobar sequestration and extramedullary hematopoiesis).

    A Novel Method: Super-selective Adrenal Venous Sampling.
    J Vis Exp 2017 Sep 15(127). Epub 2017 Sep 15.
    Endocrinology & Diabetes Center, Yokohama Rosai Hospital;
    Primary aldosteronism (PA) and subclinical Cushing's syndrome (SCS) are conditions in which the adrenal glands autonomously produce excessive amounts of aldosterone and cortisol, respectively. The conventional adrenal venous sampling (cAVS) method collects blood samples from both adrenal central veins and is useful for identifying the laterality of excess hormone production in a unilateral lesion(s), as documented in PA cases. In cAVS, plasma cortisol concentrations (PCCs) are used to normalize plasma aldosterone concentrations (PACs). Read More

    Luteinizing Hormone and GATA4 Action in the Adrenocortical Tumorigenesis of Gonadectomized Female Mice.
    Cell Physiol Biochem 2017 4;43(3):1064-1076. Epub 2017 Oct 4.
    Institute of Biomedicine, University of Turku, Turku, Finland.
    Background/aims: Physiological role of luteinizing hormone (LH) and its receptor (LHCGR) in adrenal remains unknown. In inhibin-α/Simian Virus 40 T antigen (SV40Tag) (inhα/Tag) mice, gonadectomy-induced (OVX) elevated LH triggers the growth of transcription factor GATA4 (GATA4)-positive adrenocortical tumors in a hyperplasia-adenoma-adenocarcinoma sequence.

    Methods: We investigated the role of LHCGR in tumor induction, by crossbreeding inhα/Tag with Lhcgr knockout (LuRKO) mice. Read More

    Genetic causes of functional adrenocortical adenomas.
    Endocr Rev 2017 Aug 2. Epub 2017 Aug 2.
    INSERM, UMRS_970, Paris Cardiovascular Research Center, Paris, France.
    Aldosterone and cortisol, the main mineralocorticoid and glucocorticoid hormones in humans, are produced in the adrenal cortex, which is composed of three concentric zone with specific functional characteristics. Adrenocortical adenomas (ACA) may lead to the autonomous secretion of aldosterone responsible for primary aldosteronism, the most frequent form of secondary arterial hypertension. In the case of cortisol production, ACA lead to overt or subclinical Cushing syndrome. Read More

    The subtyping of primary aldosteronism by adrenal vein sampling: sequential blood sampling causes factitious lateralization.
    J Hypertens 2017 Sep 27. Epub 2017 Sep 27.
    aDepartment of Medicine, DIMED, Clinica dell'Ipertensione Arteriosa bDepartment of Medicine, DIMED, Institute of Radiology, University of Padua, Padua, Italy *Current address for G.R. is Institute of Cardiovascular and Medical Sciences, University of Glasgow, Glasgow, UK.
    Background: The pulsatile secretion of adrenocortical hormones and a stress reaction occurring when starting adrenal vein sampling (AVS) can affect the selectivity and also the assessment of lateralization when sequential blood sampling is used. We therefore tested the hypothesis that a simulated sequential blood sampling could decrease the diagnostic accuracy of lateralization index for identification of aldosterone-producing adenoma (APA), as compared with bilaterally simultaneous AVS.

    Methods And Results: In 138 consecutive patients who underwent subtyping of primary aldosteronism, we compared the results obtained simultaneously bilaterally when starting AVS (t-15) and 15 min after (t0), with those gained with a simulated sequential right-to-left AVS technique (R ⇒ L) created by combining hormonal values obtained at t-15 and at t0.

    Materials And Methods: Six saliva samples were collected from awakening to night in 106 patients with AI and 40 controls. Read More

    Adrenal GIPR expression and chromosome 19q13 microduplications in GIP-dependent Cushing's syndrome.
    JCI Insight 2017 Sep 21;2(18). Epub 2017 Sep 21.
    Inserm U1185, Le Kremlin Bicêtre, France.
    GIP-dependent Cushing's syndrome is caused by ectopic expression of glucose-dependent insulinotropic polypeptide receptor (GIPR) in cortisol-producing adrenal adenomas or in bilateral macronodular adrenal hyperplasias. Molecular mechanisms leading to ectopic GIPR expression in adrenal tissue are not known. Here we performed molecular analyses on adrenocortical adenomas and bilateral macronodular adrenal hyperplasias obtained from 14 patients with GIP-dependent adrenal Cushing's syndrome and one patient with GIP-dependent aldosteronism.

    A 13-Steroid Serum Panel Based on LC-MS/MS: Use in Detection of Adrenocortical Carcinoma.
    Clin Chem 2017 Sep 13. Epub 2017 Sep 13.
    Department of Clinical Biochemistry (Viapath), King's College Hospital NHS Foundation Trust, London, UK.
    Background: Adrenocortical carcinoma (ACC) is a rare malignancy, with an annual incidence of 1 or 2 cases per million. Biochemical diagnosis is challenging because up to two-thirds of the carcinomas are biochemically silent, resulting from de facto enzyme deficiencies in steroid hormone biosynthesis. Urine steroid profiling by GC-MS is an effective diagnostic test for ACC because of its capacity to detect and quantify the increased metabolites of steroid pathway synthetic intermediates.

    Cortisol overproduction results from DNA methylation of CYP11B1 in hypercortisolemia.
    Sci Rep 2017 Sep 11;7(1):11205. Epub 2017 Sep 11.
    Division of Endocrinology and Hypertension, Department of Cardiovascular and Internal Medicine, Kanazawa University Graduate School of Medicine, Kanazawa, Ishikawa, 920-8640, Japan.
    Adrenocortical hormone excess, due to primary aldosteronism (PA) or hypercortisolemia, causes hypertension and cardiovascular complications. In PA, hypomethylation of aldosterone synthase (CYP11B2) is associated with aldosterone overproduction. However, in hypercortisolemia, the role of DNA methylation of 11β-hydroxylase (CYP11B1), which catalyzes cortisol biosynthesis and is highly homologous to CYP11B2, is unclear. Read More

    Adrenal venous sampling for primary aldosteronism: laboratory medicine best practice.
    J Clin Pathol 2017 Nov 11;70(11):911-916. Epub 2017 Sep 11.
    Department of Pathology and Laboratory Medicine, St. Paul's Hospital, Vancouver, Canada.
    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. Read More

    Is there a role for epithelial-mesenchymal transition in adrenocortical tumors?
    Endocrine 2017 Nov 8;58(2):276-288. Epub 2017 Sep 8.
    Endocrinology Section, Federal Hospital of Lagoa, Rio de Janeiro, Brazil.
    Purpose: Epithelial-mesenchymal transition (EMT) is a biological dynamic process by which epithelial cells lose their epithelial phenotype and acquire mesenchymal invasive and migratory characteristics. This has been postulated as an essential step during cancer progression and metastasis. Although this is well described in other tumors, the role of EMT in adrenocortical tumors (ACT) has yet to be addressed. Read More

    The diagnosis of low-grade adrenal cortical carcinoma (ACC) confined to the adrenal gland can be challenging. Although there are diagnostic and prognostic molecular tests for ACC, they remain largely unutilized. We examined the diagnostic and prognostic value of altered reticulin framework and the immunoprofile of biomarkers including IGF-2, proteins involved in cell proliferation and mitotic spindle regulation (Ki67, p53, BUB1B, HURP, NEK2), DNA damage repair (PBK, γ-H2AX), telomere regulation (DAX, ATRX), wnt-signaling pathway (beta-catenin) and PI3K signaling pathway (PTEN, phospho-mTOR) in a tissue microarray of 50 adenomas and 43 carcinomas that were characterized for angioinvasion as defined by strict criteria, Weiss score, and mitotic rate-based tumor grade.

    This study aimed to evaluate the methylation levels of G protein-coupled receptor (GPCR) related genes and the effects of methylation on mRNA expression levels in aldosterone-producing adenoma (APA). DNA methylation array and transcriptome analysis were applied in non-functioning adrenocortical adenoma (NFA) and APA. We investigated 192 GPCR-related genes and found hypo-methylation in the promoter region of 66 of these genes in APA. Read More

    The loss of normal regulation of corticosteroid secretion is important in the development of cardiovascular disease. We previously showed that microRNAs regulate the terminal stages of corticosteroid biosynthesis. Here, we assess microRNA regulation across the whole corticosteroid pathway. Read More

    Update in diagnosis and management of primary aldosteronism.
    Clin Chem Lab Med 2017 Aug 28. Epub 2017 Aug 28.
    Primary aldosteronism (PA) is a group of disorders in which aldosterone is excessively produced. These disorders can lead to hypertension, hypokalemia, hypervolemia and metabolic alkalosis. The prevalence of PA ranges from 5% to 12% around the globe, and the most common causes are adrenal adenoma and adrenal hyperplasia. Read More

    Acute hypopituitarism associated with periorbital swelling and cardiac dysfunction in a patient with pituitary tumor apoplexy: a case report.
    J Med Case Rep 2017 Aug 24;11(1):235. Epub 2017 Aug 24.
    Department of Respiratory Medicine, Uonuma Institute of Community Medicine, Niigata University Medical and Dental Hospital, Niigata, Japan.
    Background: Pituitary tumor apoplexy is a rare clinical syndrome caused by acute hemorrhage or infarction in a preexisting pituitary adenoma. It typically manifests as an acute episode of headache, visual disturbance, mental status changes, cranial nerve palsy, and endocrine pituitary dysfunction. However, not all patients present with classical symptoms, so it is pertinent to appreciate the clinical spectrum of pituitary tumor apoplexy presentation. Read More

    Cofilin is a cAMP effector in mediating actin cytoskeleton reorganization and steroidogenesis in mouse and human adrenocortical tumor cells.
