    Insights into calcium-sensing receptor trafficking and biased signalling by studies of calcium homeostasis.
    J Mol Endocrinol 2018 Mar 29. Epub 2018 Mar 29.
    C Gorvin, Institute of Metabolism and Systems Research, University of Birmingham, Birmingham, United Kingdom of Great Britain and Northern Ireland
    The calcium-sensing receptor (CaSR) is a class C G-protein coupled receptor (GPCR) that detects extracellular calcium concentrations, and modulates parathyroid hormone secretion and urinary calcium excretion to maintain calcium homeostasis. The CaSR utilises multiple heterotrimeric G-proteins to mediate signalling effects including: activation of intracellular calcium release; mitogen-activated protein kinase (MAPK) pathways; membrane ruffling; and inhibition of cAMP production. By studying germline mutations in the CaSR and proteins within its signalling pathway that cause hyper- and hypocalcaemic disorders, novel mechanisms governing GPCR signalling and trafficking have been elucidated.

We conducted a nationwide epidemiologic survey of symptomatic vitamin D deficiency to observe its incidence rate among Japanese children. A questionnaire inquiring the number of new patients with vitamin D deficiency rickets and/or hypocalcemia for 3 years was sent to 855 randomly selected hospitals with a pediatrics department in Japan.

    Incidence, predictors and therapeutic consequences of hypocalcemia in patients treated with cinacalcet in the EVOLVE trial.
    Kidney Int 2018 Mar 7. Epub 2018 Mar 7.
    Memorial University, St. John's, Canada.
    The calcimimetic cinacalcet is used to treat secondary hyperparathyroidism in patients receiving dialysis, and asymptomatic hypocalcemia is often observed following its initiation. Here we investigated the incidence, predictors and therapeutic consequences of hypocalcemia by a post hoc analysis of the randomized, double-blind, placebo-controlled EValuation Of Cinacalcet Hydrochloride Therapy to Lower CardioVascular Events (EVOLVE) trial. Hypocalcemia was classified as mild (total serum calcium 8. Read More

    Secondary hyperparathyroidism develops in CKD due to a combination of vitamin D deficiency, hypocalcemia, and hyperphosphatemia, and it exists in nearly all patients at the time of dialysis initiation. There is insufficient data on whether to prefer vitamin D analogs compared with calcimimetics, but the available evidence suggests advantages with combination therapy. Calcium derangements, patient adherence, side effects, and cost limit the use of these agents. Read More

    Effects of denosumab on bone mineral density in Japanese women with osteoporosis treated with aromatase inhibitors for breast cancer.
    J Bone Miner Metab 2018 Mar 8. Epub 2018 Mar 8.
    Department of Endocrine and Breast Surgery, Kyoto Prefectural University of Medicine, 465 Kajii-cho, Kawaramachi-hirokoji, Kamigyo-ku, Kyoto, 602-8566, Japan.
    Adjuvant aromatase inhibitor (AI) therapy, for hormone receptor-positive breast cancer, in postmenopausal women is associated with bone loss, leading to an increased risk of fractures. Denosumab, an antibody raised against the receptor activator of nuclear factor-κB ligand, has been proven to protect against AI-induced bone loss. Hence, we aimed to determine whether denosumab is effective in postmenopausal Japanese women with osteoporosis, treated with AI. Read More

    Etidronate for Prevention of Ectopic Mineralization in Patients With Pseudoxanthoma Elasticum.
    J Am Coll Cardiol 2018 Mar;71(10):1117-1126
    Department of Vascular Medicine, University Medical Center Utrecht, Utrecht University, Utrecht, the Netherlands. Electronic address:
    Background: In pseudoxanthoma elasticum (PXE), low pyrophosphate levels may cause ectopic mineralization, leading to skin changes, visual impairment, and peripheral arterial disease.

    Objectives: The authors hypothesized that etidronate, a pyrophosphate analog, might reduce ectopic mineralization in PXE.

    Methods: In the Treatment of Ectopic Mineralization in Pseudoxanthoma Elasticum trial, adults with PXE and leg arterial calcifications (n = 74) were randomly assigned to etidronate or placebo (cyclical 20 mg/kg for 2 weeks every 12 weeks). Read More

    Metabolic predictors of peri-partum diseases and their association with parity in dairy cows.
    Res Vet Sci 2018 Feb 19;118:191-198. Epub 2018 Feb 19.
    Veterinary Faculty, Federal University of Pampa, Uruguaiana, Brazil.
    The predictive values of plasma non-esterified fatty acid (NEFA), beta-hydroxybutyrate (BHB), cholesterol, albumin and calcium to predict risk of peripartum diseases in primiparous (PP) and multiparous (MP) Holstein cows was investigated. Besides it was assessed if the health status interacted with parity on body condition score and metabolic profiles during the transition period. Dairy cows (126 PP and 182 MP) from a commercial dairy free stall herd (loose-housing system) were weekly body condition scored and tail bled for metabolites determination from -3 to +4 weeks relative to calving.

    Cinacalcet for Treatment of Chronic Kidney Disease-Mineral and Bone Disorder: A Meta-Analysis of Randomized Controlled Trials.
    Nephron 2018 Mar 7. Epub 2018 Mar 7.
    Division of Nephrology, Department of Medicine, Faculty of Medicine, King Chulalongkorn Memorial Hospital, Chulalongkorn University, Bangkok, Thailand.
    Background: Cinacalcet could decrease serum calcium, phosphate, and parathyroid hormone (PTH) in previous meta-analyses. However, the effect of cinacalcet on the new biomarkers such as fibroblast growth factor-23 (FGF-23), bone markers, and vascular calcification are still unestablished. We conducted a meta-analysis to examine the effects of cinacalcet on all laboratory and clinical spectrums of chronic kidney disease-mineral bone disorders (CKD-MBD). Read More

    Case report of primary intestinal lymphangiectasia diagnosed in an octogenarian by ileal intubation and by push enteroscopy after missed diagnosis by standard colonoscopy and EGD.
    Medicine (Baltimore) 2018 Jan;97(3):e9649
    Department of Pathology, William Beaumont Hospital.
    Rationale: Primary intestinal lymphangiectasia (PIL) is a rare, presumably congenital lesion that is usually diagnosed in patients < 3 years old, is rarely first diagnosed in adulthood, and when first diagnosed in adulthood typically presents with symptoms for many years. Although PIL is often identified by endoscopic abnormalities, it must be emphasized that the jejunoileum/distal duodenum must be intubated for diagnosis because the lesions are present in these regions. This work demonstrates that 1)-PIL can occur in an octogenarian; 2)-shows that the characteristic endoscopic findings are not found at colonoscopy without terminal ileal intubation; and 3)-may be missed at standard EGD without distal duodenal intubation.
