An association of VDR gene polymorphism in hypovitaminosis D mediated secondary hyperparathyroidism in adolescent girls; a tertiary hospital study in central India.

Steroids 2022 May 26;185:109054. Epub 2022 May 26.

Department of Biochemistry, All India Institute of Medical Sciences (AIIMS) Bhopal, Madhya Pradesh, India.

Vitamin D is required to maintain normal serum calcium and phosphate levels that help normal bone mineralization, nerve conduction, muscle contraction, immune function, cell proliferation, and differentiation. Interventions including vitamin D supplementation may not improve vitamin D deficiency, as various complex genomic actions could contribute to vitamin D deficiency in the Indian population. Thus, we assessed hypovitaminosis D's relationship with vitamin D receptor (VDR) gene polymorphism and evaluated parathyroid hormone (PTH) levels in seemingly healthy adolescent school-going girls.

An essential practice summary of the new EANM guidelines for parathyroid imaging.

Q J Nucl Med Mol Imaging 2022 Jun 15;66(2):93-103. Epub 2022 Feb 15.

EANM Dosimetry Committee.

Parathyroid imaging is essential for the detection and localization of hyperfunctioning parathyroid tissue in patients with primary hyperparathyroidism (pHPT). Surgical treatment of pHPT mainly consists of minimally invasive parathyroidectomy (MIP), as a single adenoma represents the most common cause of this endocrine disorder. Successful surgery requires an experienced surgeon and relies on the correct preoperative detection and localization of hyperfunctioning parathyroid glands. Read More

Cortical porosity development and progression is mitigated after etelcalcetide treatment in an animal model of chronic kidney disease.

Bone 2022 04 24;157:116340. Epub 2022 Jan 24.

Department of Anatomy, Cell Biology & Physiology, Indiana University School of Medicine, Indianapolis, IN, United States; Department of Medicine, Division of Nephrology, Indiana University School of Medicine, Indianapolis, IN, United States; Roudebush Veterans Administration Medical Center, Indianapolis, IN, United States. Electronic address:

Purpose: Chronic kidney disease (CKD) leads to increased bone fragility and risk of fracture. Cortical deteriorations, including cortical porosity, are key factors in fracture susceptibility in CKD. Since secondary hyperparathyroidism is common in CKD individuals and contributes to cortical deterioration, we hypothesized that reducing parathyroid hormone (PTH) may modulate CKD-induced cortical porosity.

Department of Radiology, College of Medicine, Qassim University, Buraidah, 6655-51452, Saudi Arabia.

Skeletal changes are a common complication in patients with chronic kidney disease and traditionally labelled as renal osteodystrophy. Uremic leontiasis ossea is a rare and severe form of renal osteodystrophy with characteristic overgrowth of the craniofacial bones. Imaging, in particular computed tomography, is valuable for the diagnosis and management of such rare condition. Read More

Parathyroid Hormone-Related Changes of Bone Structure.

Physiol Res 2021 11;70(Suppl 1):S3-S11

5th department of Internal Medicine, Comenius University Faculty of Medicine, University Hospital Bratislava, Bratislava, Slovakia.

Parathyroid hormone (PTH) increases the release of serum calcium through osteoclasts, which leads to bone resorption. Primary, PTH stimulates osteoblasts leading to increase RANKL (receptor activator for nuclear factor kappa-B ligand) expression and thus differentiation of osteoclasts. In kidneys, PTH increases calcium and decrease phosphate reabsorption. Read More

High bone turnover and hyperparathyroidism after surgery for tumor-induced osteomalacia: A case series.

Bone Rep 2021 Dec 9;15:101142. Epub 2021 Oct 9.

Department of Clinical Chemistry, St. Vincent's University Hospital, Dublin, Ireland.

Tumor-induced osteomalacia (TIO) is an ultrarare disorder that is caused by renal phosphate wasting due to uncontrolled tumoral production of fibroblast growth factor 23 (FGF23) from phosphaturic mesenchymal tumors. Surgical removal of the tumor is curative. There is limited information on the biochemical changes in mineral metabolism and bone remodeling activity after surgery, but it is reported that surgery is followed by a hungry bone syndrome (HBS) with hypocalcemia and secondary hyperparathyroidism.
