Clin Kidney J 2019 Apr 20;12(2):269-280. Epub 2018 Jul 20.

Division of Nephrology, Ambroise Paré University Medical Center, APHP, University of Paris Ouest (UVSQ), Boulogne Billancourt/Paris, France.

Chronic kidney disease (CKD) is often associated with a mineral and bone disorder globally described as CKD-Mineral and Bone Disease (MBD), including renal osteodystrophy, the latter ranging from high bone turnover, as in case of secondary hyperparathyroidism (SHPT), to low bone turnover. The present article summarizes the important subjects that were covered during 'The Parathyroid Day in Chronic Kidney Disease' CME course organized in Paris in September 2017. It includes the latest insights on parathyroid gland growth, parathyroid hormone (PTH) synthesis, secretion and regulation by the calcium-sensing receptor, vitamin D receptor and fibroblast growth factor 23 (FGF23)-Klotho axis, as well as on parathyroid glands imaging.

Intraoperative verification of parathyroid glands in primary and secondary hyperparathyroidism using near-infrared autofluorescence (IOPA).

Updates Surg 2019 Apr 3. Epub 2019 Apr 3.

Schwarzwald-Baar Klinikum Villingen-Schwenningen, Klinikstrasse 11, Villingen-Schwenningen, 78052, Germany.

Intraoperative verification of parathyroid glands relies on visual identification by the surgeon and, with some time delay, on serum parathormon measurements and frozen section. Fluorescence imaging, however, is an instant on-table method for direct visualization of parathyroid tissue which is known to exhibit increased autofluorescence intensity when exposed to near-infrared light. In this retrospective observational study, we evaluate the clinical use of this method in a series of patients with primary and secondary hyperparathyroidism. Read More

Skeletal status assessment by quantitative ultrasound and bone densitometry in children with different renal conditions.

Osteoporos Int 2018 Dec 20;29(12):2667-2675. Epub 2018 Aug 20.

Chair of Internal Medicine, Diabetology and Nephrology, Metabolic Bone Diseases Unit, School of Medicine with the Division of Dentistry in Zabrze, Medical University of Silesia in Katowice, Katowice, Poland.

Two methods of skeletal status assessment-quantitative ultrasound (QUS) and densitometry (DXA)-were applied and compared in a group of children with different renal disorders. Skeletal assessments in children with different renal conditions should rather not be based on a single diagnostic tool. Lumbar spine DXA is very effective to reveal disturbances secondary to glucocorticoids, whereas total body DXA and QUS are both better in identification of disturbances related to decreased GFR.

Raman Spectroscopic and Microscopic Analysis for Monitoring Renal Osteodystrophy Signatures.

Biosensors (Basel) 2018 Apr 8;8(2). Epub 2018 Apr 8.

Department of Physics, University of Texas at El Paso, El Paso, TX 79968, USA.

Defining the pathogenesis of renal osteodystrophy (ROD) and its treatment efficacy are difficult, since many factors potentially affect bone quality. In this study, confocal Raman microscopy and parallel statistical analysis were used to identify differences in bone composition between healthy and ROD bone tissues through direct visualization of three main compositional parametric ratios, namely, calcium content, mineral-to-matrix, and carbonate-to-matrix. Besides the substantially lower values found in ROD specimens for these representative ratios, an obvious accumulation of phenylalanine is Raman spectroscopically observed for the first time in ROD samples and reported here.

Should all patients with hyperparathyroidism be screened for a CDC73 mutation?

Endocrinol Diabetes Metab Case Rep 2018 8;2018. Epub 2018 Mar 8.

Endocrinology Department, Townsville Hospital, Townsville, Queensland, Australia.

Primary hyperparathyroidism (PH) is a common endocrine abnormality and may occur as part of a genetic syndrome. Inactivating mutations of the tumour suppressor gene have been identified as accounting for a large percentage of hyperparathyroidism-jaw tumour syndrome (HPT-JT) cases and to a lesser degree account for familial isolated hyperparathyroidism (FIHP) cases. Reports of whole gene deletions are exceedingly rare. Read More

Cortical and trabecular bone are equally affected in rats with renal failure and secondary hyperparathyroidism.

BMC Nephrol 2018 02 2;19(1):24. Epub 2018 Feb 2.

Musculoskeletal Disease Center, VA Loma Linda Healthcare System, 11201 Benton Street, Loma Linda, CA, 92357, USA.

Background: Changes in mineral metabolism and bone structure develop early in the course of chronic kidney disease and at end-stage are associated with increased risk of fragility fractures. The disruption of phosphorus homeostasis leads to secondary hyperparathyroidism, a common complication of chronic kidney disease. However, the molecular pathways by which high phosphorus influences bone metabolism in the early stages of the disease are not completely understood. Read More

Nuclear Medicine Methods for Evaluation of Abnormal Parathyroid Glands in Patients with Primary and Secondary Hyperparathyroidism.

Folia Med (Plovdiv) 2017 12;59(4):396-404

Complex Oncology Center, Plovdiv, Bulgaria

Considered rare disease in the past, primary hyperparathyroidism (PHPT) has dramatically increased in incidence over the past thirty years with the introduction of routine calcium measurements; it is now approximately 42 per 100 000 persons. By far, the most common lesion found in patients with PHPT is the solitary parathyroid adenoma, occurring in 85%-90% of patients, while in the rest 10%- 15% primary hyperplasia of the parathyroid glands is present. Currently, the most widely used surgical approach is minimally invasive parathyroidectomy which is associated with less post-surgery complications and shorter operation time. Read More
