Severe hypocalcemia (SH) is a common and serious complication in dialysis patients with secondary hyperparathyroidism (SHPT) after parathyroidectomy (PTX). The aim is to explore the risk predictors of SH in post-PTX dialysis ESRD patients with SHPT. 129 consecutive dialysis patients with SHPT underwent PTX were retrospectively reviewed. A total of 22 clinical parameters were included in the study. SH was defined as the minimum values of serum calcium lower than 1.875 mmol/L (7.5 mg/dL) after surgery. Univariate analysis showed that pruritus, lumbar X-ray changes of renal osteodystrophy, pre- and post-operative intact parathyroid hormone (iPTH), Calcium, alkaline phosphatase, and gland mass were significantly different between SH and non-SH groups...

Recent improvements in our understanding of physiology have altered the way in which bone is perceived: no longer is it considered as simply the repository of divalent ions, but rather as a sophisticated endocrine organ with potential extraskeletal effects. Indeed, a number of pathologic conditions involving bone in different ways can now be reconsidered from a bone-centred perspective. For example, in metabolic bone diseases like osteoporosis (OP) and renal osteodystrophy (ROD), the association with a worse cardiovascular outcome can be tentatively explained by the possible derangements of three recently discovered bone hormones (osteocalcin, fibroblast growth factor 23 and sclerostin) and a bone-specific enzyme (alkaline phosphatase)...

Hyperparathyroidism (HPT) is an endocrine metabolic disorder characterized by increased secretion of parathyroid hormone. Untreated secondary HPT leads to renal osteodystrophy (ROD). Facial skeletal abnormalities in patients with ROD are rare. The purpose of this paper is to report a conservative surgical approach of exuberant osteitis fibrosa lesions in patient with chronic kidney disease. A 24-year-old female was referred to maxillofacial surgery department with giants ROD affecting palate, maxilla, and mandible, resulting in esthetic and functional impairment...

Chronic kidney disease (CKD) causes dysregulation of mineral metabolism, vascular calcification and renal osteodystrophy, an entity called 'CKD-Mineral and Bone Disorder' (CKD-MBD). Here we determine whether metformin, an anti-diabetic drug, exerts favorable effects on progressive, severe CKD and concomitant mineral metabolism disturbances. Rats with CKD-MBD, induced by a 0.25% adenine diet for eight weeks, were treated with 200 mg/kg/day metformin or vehicle from one week after CKD induction onward. Severe, stable CKD along with marked hyperphosphatemia and hypocalcemia developed in these rats which led to arterial calcification and high bone turnover disease...

PURPOSE OF REVIEW: Klotho is a transmembrane protein that acts as a co-receptor for fibroblast growth factor 23 (FGF23). Recent investigations have discovered the presence of Klotho in bone-forming osteoblasts and osteocytes. This review summarizes emerging literature on the roles of bone Klotho in mineral and bone metabolism and discusses their possible involvement in renal osteodystrophy. RECENT FINDINGS: Mouse genetic studies have demonstrated that loss of Klotho in osteocytes leads to increased bone formation and bone volume...

PURPOSE: Chronic kidney disease (CKD) is a progressive condition characterized by irreversible loss of functional nephron mass due to variety of causes; an inevitable complication of CKD is metabolic bone disease, and this pathology is called as renal osteodystrophy (ROD). In this study, we aimed to determine the levels of serum sRANKL and intracellular NF-κB levels in peripheral blood osteoclast precursor cells in patients with stage 3 CKD. MATERIALS AND METHODS: Forty-one male patients aged 35-60 with CKD identified as stage 3 according to GFR calculated on the basis of creatinine values and 27 healthy male subjects with age ranging from 40 to 60 as control group were included in this study...

Background: Parathyroidectomy (PTX) is done in cases of secondary hyperparathyroidism from chronic kidney disease to improve renal osteodystrophy. Despite this widespread practice, clinical outcomes regarding the benefits of this procedure are still lacking. Most studies in the literature have opted to report the laboratory outcome instead. Our study aimed to evaluate the postoperative clinical course for patients who had undergone total PTX without autoimplantation. Methods and results: All patients who underwent PTX between January 2010 and February 2014 in a tertiary referral center were included in this study and followed up for 12 months...

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...

Background Renal osteodystrophy is common in advanced CKD, but characterization of bone turnover status can only be achieved by histomorphometric analysis of bone biopsy specimens (gold standard test). We tested whether bone biomarkers and high-resolution peripheral computed tomography (HR-pQCT) parameters can predict bone turnover status determined by histomorphometry. Methods We obtained fasting blood samples from 69 patients with CKD stages 4-5, including patients on dialysis, and 68 controls for biomarker analysis (intact parathyroid hormone [iPTH], procollagen type 1 N-terminal propeptide [PINP], bone alkaline phosphatase [bALP], collagen type 1 crosslinked C-telopeptide [CTX], and tartrate-resistant acid phosphatase 5b [TRAP5b]) and scanned the distal radius and tibia of participants by HR-pQCT...

BACKGROUND: The hyperparathyroidism (HPT) is a condition in which the parathyroid hormone (PTH) levels in the blood are increased. HPT is categorised into primary, secondary and tertiary. A rare entity that occurs in the lower jaw in association with HPT is the so-called brown tumour, which an osteolytic lesion is predominantly occurring in the lower jaw. It is usually a manifestation of the late stage of the disease. Osteosclerotic changes in other bones are almost always associated with renal osteodystrophy in secondary HPT and are extremely rare in primary HPT...

Progressive chronic kidney diseases (CKDs) are on the rise worldwide. However, the sequence of events resulting in CKD progression remain poorly understood. Animal models of CKD exploring these issues are confounded by systemic toxicities or surgical interventions to acutely induce kidney injury. Here we report the generation of a CKD mouse model through the inducible podocyte-specific ablation of an essential endogenous molecule, the chromatin structure regulator CCCTC-binding factor (CTCF), which leads to rapid podocyte loss (iCTCFpod-/-)...

OBJECTIVES: To describe our initial experience in the treatment of hyperparathyroidism (HPP) of renal cause using total or subtotal parathyroidectomy, autoimplant and cryopreservation in pediatric patients. Secondary HPP is the increased function of the parathyroid hormone (PTH) due to an abnormal phosphocalcic metabolism in patients with chronic renal failure (CRF). This situation produces increased bone resorption resulting in osteodystrophy and endovascular calcifications. Surgical treatment is aimed to diminish the level of PTH in CRF patients, to avoid HPP complications...

A finding of high bone mineral density (BMD) from routine dual-energy X-ray absorptiometry (DXA) screening is not uncommon. No consensus exists about the definition of high BMD, and T-score and/or Z-score cutoffs of ≥+2.5 or ≥+4 have been suggested. The many disorders that can result in high BMD are usually classified based on whether the BMD changes are focal vs. generalized or acquired vs. constitutional. In over half the cases, careful interpretation of the DXA report and images identifies the cause as an artefact (e...

Renal osteodystrophy can cause calvarial hypertrophy and narrowing of the neural canals and foramina. Compressive optic neuropathy is extremely rare in renal osteodystrophy and was reported once only. The authors report bilateral, simultaneous compressive optic neuropathy secondary to renal osteodystrophy with features of uremic leontiasis ossea in chronic renal failure caused by branchio-oto-renal syndrome. Because of the extensive calvarial hypertrophy and the surgical difficulties envisaged with optic canal decompression, conservative approach was pursued...

Sclerostin is a soluble antagonist of canonical Wnt signaling and a strong inhibitor of bone formation. We present experimental data on the role of sclerostin in chronic kidney disease - bone mineral disorder (CKD-MBD). METHODS: We performed 5/6 nephrectomies in 36-week-old sclerostin-deficient (SOST-/- ) B6-mice and in C57BL/6J wildtype (WT) mice. Animals received a high phosphate diet for 11weeks. The bones were analyzed by high-resolution micro-computed tomography (μCT) and quantitative bone histomorphometry...

Excessive skeletal radioisotope uptake in relation to soft tissues along with absent or faint activity in the genitourinary tract on skeletal scintigraphy is known as a "superscan." Prostate cancer is the most common cause of superscan in skeletal scintigraphy due to diffuse skeletal metastases. However, prostate cancer may cause secondary renal osteodystrophy leading to metabolic superscan also. Differentiating between these two entities are important as treatment options are different. We, hereby, describe a case of prostatic adenocarcinoma presented with metabolic superscan on methylene diphosphonate skeletal scintigraphy and demonstrate the utility of single emission computed tomography-computed tomography in differentiating between two entities...

PURPOSE: Lumbar spinal stenosis is characterized by the narrowing of the spinal canal, which subsequently induces impingement of neural elements in the lumbar spine. Thus, symptoms of lumbar spinal stenosis are typically associated with damage to those neural elements. Herewith, we target the genitourinary symptoms of lumbar spinal stenosis and the importance of differentiating these symptoms from other genitourinary pathologies, namely benign prostatic hyperplasia. MATERIALS AND METHODS: MeSH and keywords relevant to lumbar spinal stenosis and the organs of the urinary tract were used to a guide a literature search on MEDLINE...

REVIEW
Ladan Zand, Rajiv Kumar
Chronic kidney disease (CKD) and end-stage renal disease (ESRD) are associated with abnormalities in bone and mineral metabolism, known as CKD-bone mineral disorder. CKD and ESRD cause skeletal abnormalities characterized by hyperparathyroidism, mixed uremic osteodystrophy, osteomalacia, adynamic bone disease, and frequently enhanced vascular and ectopic calcification. Hyperparathyroidism and mixed uremic osteodystrophy are the most common manifestations due to phosphate retention, reduced concentrations of 1,25-dihydroxyvitamin D, intestinal calcium absorption, and negative calcium balance...
