    Functional TASK-3-Like Channels in Mitochondria of Aldosterone-Producing Zona Glomerulosa Cells.
    Hypertension 2017 Jun 19. Epub 2017 Jun 19.
    From the Departments of Pharmacology (J.Y., D.M., W.E.M., N.A.G., D.A.B., P.Q.B.) and Psychology (A.E.), University of Virginia School of Medicine, Charlottesville; Silverback Therapeutics, Inc, Seattle, WA (C.A.C.); and Department of Neuroscience, Merck & Co, Inc, West point, PA (V.P.S.).
    Ca(2+) drives aldosterone synthesis in the cytosolic and mitochondrial compartments of the adrenal zona glomerulosa cell. Membrane potential across each of these compartments regulates the amplitude of the Ca(2+) signal; yet, only plasma membrane ion channels and their role in regulating cell membrane potential have garnered investigative attention as pathological causes of human hyperaldosteronism. Previously, we reported that genetic deletion of TASK-3 channels (tandem pore domain acid-sensitive K(+) channels) from mice produces aldosterone excess in the absence of a change in the cell membrane potential of zona glomerulosa cells.

    Somatic and inherited mutations in primary aldosteronism.
    J Mol Endocrinol 2017 Jul 11;59(1):R47-R63. Epub 2017 Apr 11.
    INSERMUMRS_970, Paris Cardiovascular Research Center, Paris, France.
    Primary aldosteronism (PA), the most common form of secondary hypertension, is caused in the majority of cases by unilateral aldosterone-producing adenoma (APA) or bilateral adrenal hyperplasia. Over the past few years, somatic mutations in KCNJ5, CACNA1D, ATP1A1 and ATP2B3 have been proven to be associated with APA development, representing more than 50% of sporadic APA. The identification of these mutations has allowed the development of a model for APA involving modification on the intracellular ionic equilibrium and regulation of cell membrane potential, leading to autonomous aldosterone overproduction.

    Am J Hypertens 2017 May;30(5):484-489
    Department of Nephrology and Hypertension, Hannover Medical School, Hannover, Germany.
    Background: Hyperaldosteronism is well known cause of secondary hypertension. However, the importance of aldosterone for the much larger group of patients with primary hypertension is less clear. We hypothesized that in young subjects with primary hypertension, the rise of plasma aldosterone levels in response to head-up tilt testing as a stress stimulus is exaggerated. Read More

    Primary Aldosteronism as a Risk Factor for Vertebral Fracture.
    J Clin Endocrinol Metab 2017 Apr;102(4):1237-1243
    Department of Internal Medicine 1, Shimane University Faculty of Medicine, Izumo, Shimane 693-8501, Japan, and.
    Context: Some observational studies have revealed an association between excessive aldosterone levels and reduced bone mineral density (BMD). However, whether patients with primary aldosteronism (PA) are at higher risk of fracture than healthy individuals remains unclear.

    Objective: This study aimed to clarify whether PA represents a risk factor for vertebral fracture (VF). Read More

    Adrenocortical neoplasms in adulthood and childhood: distinct presentation. Review of the clinical, pathological and imaging characteristics.
    J Pediatr Endocrinol Metab 2017 Mar;30(3):253-276
    Adrenocortical tumors (ACT) in adulthood and childhood vary in clinical, histopathological, molecular, prognostic, and imaging aspects. ACT are relatively common in adults, as adenomas are often found incidentally on imaging. ACT are rare in children, though they have a significantly higher prevalence in the south and southeast regions of Brazil. Read More

    Stroke disclosing primary aldosteronism: Report on three cases and review of the literature.
    Ann Endocrinol (Paris) 2017 Feb 4;78(1):9-13. Epub 2017 Feb 4.
    Department of Neurology, Military Hospital, 1008, Montfleury, 1089 Tunis, Tunisia.
    Objectives: There is a growing evidence of increased risk of cerebrovascular events in primary aldosteronism (PA). Nevertheless, acute neurologic ailment as presenting feature of PA is uncommon. Our aim is to highlight the diagnosis challenges in stroke unmasking PA and to discuss the underlying physiopathology and management dilemmas. Read More

    Anatomical Variations of the Right Adrenal Vein: Concordance Between Multidetector Computed Tomography and Catheter Venography.
    Hypertension 2017 Mar 30;69(3):428-434. Epub 2017 Jan 30.
    From the Department of Diagnostic Radiology (K.O., H.O., Y.T., T.M., K.S., K.T.), Department of Urology (Y.A.), and Division of Nephrology, Endocrinology, and Vascular Medicine (R.M., F.S.), Tohoku University Hospital, Sendai, Japan.
    Adrenal venous sampling is the most reliable diagnostic procedure to determine surgical indications in primary aldosteronism. Because guidelines recommend multidetector computed tomography (CT) to evaluate the adrenal gland, some past reports used multidetector CT as a guide for adrenal venous sampling. However, the detailed anatomy of the right adrenal vein and its relationship with an accessory hepatic vein remains uncertain. Read More

    Assessment of the Aldosteronona resolution score as a predictive resolution score of hypertension after adrenalectomy for aldosteronoma in French patients.
    Langenbecks Arch Surg 2017 Mar 22;402(2):309-314. Epub 2017 Jan 22.
    Clinique de Chirurgie Digestive et Endocrinienne (CCDE), Institut des Maladies de l'Appareil Digestif (IMAD), CHU Hôtel-Dieu, 1 place Alexis Ricordeau, 44093, Nantes cedex 1, France.
    Purpose: Aldosteronoma Resolution Score (ARS) is a predictive score for cure of hypertension after adrenalectomy for hyperaldosteronism and has been validated in American patients. The aim of the study was to validate this score in a French population.

    Method: Data concerning patients operated from 2002 to 2015 in 7 French University Hospitals were retrospectively collected. Read More

    Evacetrapib: Another CETP Inhibitor for Dyslipidemia With No Clinical Benefit.
    Cardiol Rev 2017 Mar/Apr;25(2):43-52
    From the *Department of Medicine, Ronald Reagan UCLA Medical Center, Los Angeles, CA; and †Department of Medicine, New York Medical College/Westchester Medical Center, Valhalla, NY.
    Evacetrapib is a cholesteryl ester transfer protein (CETP) inhibitor that has been recently studied as a cholesterol modifying agent to reduce cardiovascular risk and mortality in high risk cardiovascular disease patients. Evacetrapib acts to decrease lipid exchange through CETP inhibition. CETP acts to transfer cholesteryl esters from high-density lipoprotein-cholesterol (HDL-C) to low-density lipoprotein cholesterol (LDL-C) and very-low-density lipoprotein (VLDL-C). Read More
