INTRODUCTION: It is well documented that patients with osteoporosis (OP) have high incidence of hypercalciuria (HC). However, the mechanism of HC in patients with OP is not well established. It is thought to be the result of high bone turnover (HBT) with excessive bone resorption. OP also frequently presents with low bone turnover (LBT). At this time, it is not clear whether OP with LBT is also associated with hypercalciuria. PURPOSE: The purpose of this study is to evaluate urinary calcium excretion in osteoporotic patients with HBT and LBT...

BACKGROUND: Secondary hyperparathyroidism (SHPT) is a common complication of chronic kidney disease (CKD) leading high mortality and even long-term morbidity. SHPT is manifested by elevation of parathyroid hormone (PTH) and accurate determining the level of serum PTH is very essential for early diagnosis of SHPT secondary to CKD. It is very important to match the values obtained for intact parathormone (iPTH) and 1- 84 PTH with the minimized measurement bias. OBJECTIVES: The present study aimed to first determine the agreement value between the iPTH and 1- 84 PTH measures in patients with hyperparathyroidism secondary to endstage renal disease under chronic hemodialysis...

Paricalcitol is approved for prevention and therapy of secondary hyperparathyroidism (sHPT) in patients with chronic kidney disease (CKD), with only short-term data in clinical routine settings. A 12-month observational study was conducted in Germany and Austria (90 centers, 761 patients) from 2008 to 2013. Laboratory values, demographical, and clinical data were documented in 629 dialysis patients and 119 predialysis patients. In predialysis patients, median intact parathormone (iPTH) was 180.0 pg/mL (n = 105) at the start of the study, 115...

OBJECTIVE: Little is known about the natural changes in parathyroid function after successful parathyroid surgery for primary hyperparathyroidism. The association of intact parathyroid hormone (iPTH) and calcium (Ca) with "temporary hypoparathyroidism" and "hungry bone syndrome" (HBS) was evaluated. DESIGN: Potential risk factors for temporary hypoparathyroidism and HBS were evaluated by taking blood samples before surgery, intra-operatively, at postoperative day (POD) 1, at POD 5 to 7, in postoperative week (POW) 8 and in postoperative month (POM) 6...

Using a forward genetics approach to map loci in a mouse skin cancer model, we previously identified a genetic locus, Skin tumour modifier of MSM 1 (Stmm1) on chromosome 7, conferring strong tumour resistance. Sub-congenic mapping localized Parathyroid hormone (Pth) in Stmm1b. Here, we report that serum intact-PTH (iPTH) and a genetic polymorphism in Pth are important for skin tumour resistance. We identified higher iPTH levels in sera from cancer-resistant MSM/Ms mice compared with susceptible FVB/NJ mice...

BACKGROUND: Parathyroid water-clear cell hyperplasia (WCCH) and water-clear cell adenoma (WCCA) are rare causes of primary hyperparathyroidism. The frequency of WCCH seems to be less than 1% of all primary hyperplasia. CASE PRESENTATION: We report a 53-year-old woman with a large unilateral water clear cell parathyroid hyperplasia associated with primary hyperparathyroidism and severe osteoporosis. Ultrasonography showed a 5.4 cm multilobulated hypoechoic well defined mass localized in the lower half of the left thyroid lobe...

BACKGROUND: Secondary hyperparathyroidism (SHPT) is a serious major complication in hemodialysis patients with chronic kidney disease. Long-term maintenance of serum phosphate, calcium, and parathyroid hormone (PTH) levels in appropriate ranges in these patients is a major challenge. We investigated the efficacy and safety of long-term treatment with etelcalcetide, a novel intravenous calcimimetic, in Japanese SHPT patients on long-term hemodialysis. METHODS: This study was a multicenter open-label study...

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in patients with end-stage renal disease. Chronic kidney disease (CKD)-associated cardiovascular mortality is more prevalent in those with diastolic heart failure and is an early predictor, while increased left ventricular mass (LVM) is a strong independent risk factor. Hypovitaminosis D is extensively being studied as a nontraditional risk factor for CVD. The aim of the present study is to look at the association of Vitamin D and other parameters of mineral bone disorder (MBD) with diastolic dysfunction and LVM in nondiabetic young adult patients with CKD...

Vitamin D has immunomodulating properties. The nuclear receptor for vitamin D is expressed in several immune cells, which convert 25-hydroxyvitamin D (25OHD) to the active form 1,25 hydroxyvitamin D [1,25(OH)2 D]. Under conditions of infection, 1,25(OH)2 D promotes production of cathelicidin (an antimicrobial peptide) in monocytes and activated macrophages. In vitro studies have shown the ability of cathelicidin to inhibit replication of human immunodeficiency virus (HIV-1) in T CD4 lymphocytes and macrophages...

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...
