BACKGROUND: Observational studies have shown a beneficial effect of obesity on bone health; however, most of those studies were not based on bone biopsies. Metabolic syndrome (MetS) could have an effect on bone remodeling. However, there are no data on the effects of MetS in the presence of renal osteodystrophy. OBJECTIVE: The aim of this study was to investigate associations between MetS and renal osteodystrophy using the bone histomorphometric turnover-mineralization-volume (TMV) classification...

OBJECTIVE: Epidemiologic studies have suggested a link between chronic systemic inflammation and chronic kidney disease-mineral and bone disorder (CKD-MBD). Additionally, declining renal function is associated with worsening physical and cognitive function, which may potentially be explained by systemic inflammation, CKD-MBD, or both. We hypothesized that inhibiting inflammation with an interleukin-1 (IL-1) trap would improve markers of CKD-MBD as well as physical/cognitive function in patients with moderate-to-severe CKD...

AIMS: To evaluate dose-escalation of etelcalcetide (ONO-5163/AMG 416), a novel, intravenous (IV), long-acting calcium-sensing receptor agonist, for treatment of secondary hyperparathyroidism (SHPT) in Japanese hemodialysis patients. MATERIALS AND METHODS: In this multicenter study, IV injections of etelcalcetide (3 times a week for 12 weeks) were administered, with dose escalation every 4 weeks depending on changes in serum intact parathyroid hormone (iPTH) and corrected calcium (cCa)...

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) reduces obesity-related co-morbidities, such as diabetes, hypertension, and hyperlipidemia. Endocrinological abnormalities may occur as undesired side effects. Most centers routinely prescribe folic acid, cyanocobalamin (vitB12), and protein replacement in the postoperative period, but 25-OH-vitamin-D3 (vitD) and intact parathyroid hormone (iPTH) levels are not routinely followed up. The aim of this study was to identify the effects of LSG on iPTH, vitD, calcium (Ca), phosphorus (P), alkaline phosphatase (ALP), and albumin levels...

Relationships of Sclerostin, a bone anti-anabolic protein, with biomarkers of mineral bone disorders in chronic kidney disease are still unsettled, in particular in kidney transplant (KTR). In 80 KTR patients (31F/49M, 54.7±10.3 years) we studied the relationships of serum Sclerostin with eGFR, Calcium, Phosphate, Alkaline Phosphatase (AP), intact Parathyroid hormone (iPTH), soluble alpha-Klotho (sKlotho), intact Fibroblast Growth Factor 23 (iFGF23), 25-hydroxyvitamin D(25D) and 1,25-dihydroxyvitamin D (1,25D)...

BACKGROUND: To investigate the role of magnesium in biochemical and symptomatic hypocalcemia, a retrospective study was conducted. METHODS: Less-than-total thyroidectomy patients were excluded from the final analysis. Identified the risk factors of biochemical and symptomatic hypocalcemia, and investigated the correlation by logistic regression and correlation test respectively. RESULTS: A total of 304 patients were included in the final analysis...

BACKGROUND: Scleroderma is a chronic connective tissue disease of unknown etiology. Vitamin D and parathyroid hormone (PTH) that play particular functions in calcium and phosphate homeostasis may be involved in the etiology of this disorder. Klotho, the co-receptor of the fibroblast growth factor 23 (FGF-23), can interfere with calcium and phosphate metabolism. The purpose of this study was to evaluate serum Klotho, FGF-23, intact PTH (iPTH) and vitamin D levels in scleroderma patients compared with the healthy controls...

PURPOSE: The aim of this randomized-controlled trial was to validate the results of a previous prospective single-cohort observational study conducted in the same surgical unit regarding the use of concomitant intact parathyroid hormone (iPTH) and serum calcium measurement in predicting hypocalcemia after total thyroidectomy. METHODS: From January 2014 to January 2015, 150 patients underwent total thyroidectomy in our department and were randomized into two groups...

Secondary hyperparathyroidism is often associated with end stage renal disease; even after renal transplantation, hyperparathyroidism may persist, and is responsible for hypercalcemia, hypophosphatemia and elevated parathyroid hormone (iPTH) levels. Parathyroid hyperplasia is frequently associated with persistent hyperparathyroidism, and may require a surgical treatment. Here, we report hyperparathyroidism along with parathyroid hyperplasia in a 7-year-old child, which persisted after renal transplant. Calcitonin and pamidronate failed to decrease serum calcium levels; clodronate was also inefficient...

Introduction: Restless leg syndrome (RLS) is a sensory motor disorder. Patients with this syndrome have serious and uncontrollable desire to move their legs, which is mostly due to an uncomfortable feeling intensified when they are motionless. It may be a genetic disorder or secondary to iron deficiency, neurodegenerations, pregnancy, some drugs and severe kidney diseases. Objectives: This study was designed to find out the prevalence and its risk factors of RLS in hemodialysis patients. Patients and Methods: This multicenter cross-sectional study was done on 260 hemodialysis patients...

BACKGROUND: Hyperkalemia is prevalent in end-stage renal disease patients, being involved in life-threatening arrhythmias. Although polystyrene sulfonate (PS) is commonly used for the treatment of hyperkalemia, direct comparison of effects between calcium and sodium PS (CPS and SPS) on mineral and bone metabolism has not yet been studied. METHODS: In a randomized and crossover design, 20 pre-dialysis patients with hyperkalemia (>5 mmol/l) received either oral CPS or SPS therapy for 4 weeks...

OBJECTIVE: Normal or elevated 24-hour urinary calcium (Ca) excretion is a diagnostic marker in primary hyperparathyroidism (PHPT). It is used to distinguish familial hypocalciuric hypercalcaemia (FHH) from PHPT by calculating the Ca/creatinine clearance ratio (CCCR). The variance of CCCR in patients with PHPT is considerable. The aim of this study was to analyse the parameters affecting CCCR in patients with PHPT. DESIGN: The data were collected prospectively. Patients with sporadic PHPT undergoing successful surgery were included in a retrospective analysis...

OBJECTIVE: The aim of this article is to compare clinical characteristics and lab values for metabolic syndrome between primary hyperparathyroidism (PHPT) patients with different levels of serum intact parathyroid hormone (iPTH) and to determine correlation between different clinical characteristics among PHPT patients Methods: We reviewed charts of 212 PHPT patients in this retrospective study. Patients were divided into two groups according to their initial serum iPTH levels. Student's t-tests were used to compare the two groups for differences in clinical characteristics and laboratory values...

OBJECTIVE: Primary hyperparathyroidism (pHPT) is characterised by increased parathyroid hormone (PTH) secretion and consequently increased plasma calcium. During the last few decades parathyroid scintigraphy (PS), is applied in almost all patients with pPHT before surgery and specifically before minimally invasive parathyroidectomy. The aim of this study was to find the best cut-off levels of total plasma calcium and intact PTH (iPTH) that correlate with positive technetium-99m-methoxy isobutyl isonitrile ((99m)Tc-MIBI) PS and with positive subtraction PS (SPS) in patients with pHPT and thus the positive diagnostic value of these PS...

We investigated the clinical epidemiology of mineral bone disorder markers in prevalent hemodialysis (HD) patients in Xinjiang, the largest province in China. Data were obtained from 59 hospitals. A total of 3725 patients tracked from January 1 to December 31, 2014, were enrolled. Serum calcium (Ca) levels, phosphorus (P) levels, and intact parathyroid hormone (iPTH) levels were analyzed. Serum Ca levels were lower compared to the International Dialysis Outcomes and Practice Patterns Study (DOPPS4) and the Chinese DOPPS...

PURPOSE: Parathormone (PTH) is a very potent uraemic toxin, which affects calcium/phosphate homeostasis in patients with end-stage renal disease (ESRD). It also plays the role in uraemic autonomic neuropathy. The aim of the study was to investigate the relationship between elevated PTH levels and cardiac autonomic neuropathy assessed by frequency-domain measures of heart rate variability. METHODS: 24-h ECG was performed in 106 ESRD patients and 65 healthy controls...

INTRODUCTION: Parathyroid damage or unintentional excision still affect thyroid surgery and may cause permanent hypoparathyroidism. The only way to recover the excised or ischemic gland functionality is still reimplantation. Many sites of reimplantation have been described, each of one showing both advantages and drawbacks. The aim of this study is to verify results of a new procedure called PR-FaST: Parathyroid Reimplantation in Forearm Subcutaneous Tissue, in a series of unselected patients after long-term follow-up...
