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...

BACKGROUND: The kidneys maintain acid-base homeostasis through excretion of acid as either ammonium or as titratable acids that primarily use phosphate as a buffer. In chronic kidney disease (CKD), ammoniagenesis is impaired, promoting metabolic acidosis. Metabolic acidosis stimulates phosphaturic hormones, parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF-23) in vitro, possibly to increase urine titratable acid buffers, but this has not been confirmed in humans. We hypothesized that higher acid load and acidosis would associate with altered phosphorus homeostasis, including higher urinary phosphorus excretion and serum PTH and FGF-23...

BACKGROUND: Secondary Hyperparathyroidism (SHPT) requiring parathyroidectomy (PTX) occurs more commonly in patients with progressive chronic kidney disease and in those on long-term lithium therapy. Successful PTX often results in a dramatic drop of parathyroid hormone level, relieves the patient from clinical symptoms, and reduces mortality. However, there is an ongoing debate on the optimal surgical treatment of SHPT. Currently, no clinical guidelines or trials have definitely answered the question of whether Total Parathyroidectomy (TPTX) is superior or equal to Total Parathyroidectomy with Autotransplantation (TPTX + AT)...

OBJECTIVE Posttraumatic hydrocephalus (PTH) affects 11.9%-36% of patients undergoing decompressive craniectomy (DC) and is an important cause of morbidity after traumatic brain injury (TBI). Early diagnosis and treatment of PTH can prevent further neurological compromise in patients who are recovering from TBI. There is limited data on predictors of shunting for PTH after DC for TBI. METHODS Prospectively collected data from the erythropoietin severe TBI randomized controlled trial were studied. Demographic, clinical, and imaging data were analyzed for enrolled patients who underwent a DC...

A high Ca intake has been recommended for osteoporosis prevention; however, little research has examined the relationship between dietary Ca and bone health in men. We examined associations between dietary Ca intake, bone mineral density (BMD) and change in BMD at the total body, hip and spine over 2 years in a cohort of men (mean age 57 years, BMI 26 kg/m2) from a trial. Data from the total cohort (n 323) were used in the analysis of Ca intake and BMD at baseline, and data from the placebo group (n 99) were used in the longitudinal analysis of Ca intake and change in BMD...

BACKGROUND: Mild hyperphosphatemia is a putative risk factor for cardiovascular disease [CVD], loss of kidney function, and mortality. Very limited data are available from sizable multicenter kidney transplant recipient (KTR) cohorts assessing the potential relationships between serum phosphorus levels and the development of CVD outcomes, transplant failure, or all-cause mortality. STUDY DESIGN: Cohort study. SETTING & PARTICIPANTS: The Folic Acid for Vascular Outcome Reduction in Transplantation (FAVORIT) Trial, a large, multicenter, multiethnic, controlled clinical trial that provided definitive evidence that high-dose vitamin B-based lowering of plasma homocysteine levels did not reduce CVD events, transplant failure, or total mortality in stable KTRs...

BACKGROUND: In primary hyperparathyroidism, successful parathyroidectomy leads to improved bone mineral density in the majority of cases. Our aim was to further explore the relationship between hypercalciuria, kidney function, and bone recovery after parathyroidectomy. METHODS: Bone mineral density, estimated glomerular filtration rate, and 24-hour urinary calcium were analyzed before and one year after parathyroidectomy in a cohort of 150 primary hyperparathyroidism patients (119 women; median age 60 [range 30-80] years) taking part in a clinical trial...

Bone loss is common in clinical practice, such as health assessment of postmenopausal women, treatment of tumor metastasis, side-effects of glucocorticoids, and skeletal manifestations of inflammatory diseases. The imbalance of remodeling between bone resorption and bone formation, the pathophysiological basis of bone loss, increases bone fragility. The treatment of bone loss is mainly carried out from the treatment of osteoporosis. There are various pharmacological therapies for bone loss, which will be introduced in 3 aspects, including anti-resorptive agents, anabolic agents and new medications...

INTRODUCTION: Etelcalcetide is a novel calcimimetic that binds and activates calcium-sensing receptors (CaSRs) for the treatment of secondary hyperparathyroidism (SHPT). METHODS: To assess titrated dosing regimens, population pharmacokinetic (PK) and PK/pharmacodynamic (PKPD) modeling of etelcalcetide was performed using NONMEM 7.2. In this analysis, plasma etelcalcetide, serum parathyroid hormone (PTH) and calcium (Ca) concentration-time data were collected from five phase I, II, and III clinical trials following single or multiple intravenous doses of etelcalcetide ranging from 2...

BACKGROUND: Secondary hyperparathyroidism (sHPT) is associated with higher mortality in dialysis patients. The calcimimetic cinacalcet reduces intact parathyroid hormone (iPTH) in dialysis patients. The randomized controlled EVOLVE trial failed to unequivocally prove survival advantage of cinacalcet in dialysis patients. However, recent post hoc analyses suggested a benefit in subgroups of dialysis patients. Large observational cohort studies may represent an option to better determine such subgroups...

Bone marrow (BM) aspirates, mobilized peripheral blood, and umbilical cord blood (UCB) have developed as graft sources for hematopoietic stem and progenitor cells (HSPCs) for stem cell transplantation and other cellular therapeutics. Individualized techniques are necessary to enhance graft HSPC yields and cell quality from each graft source. BM aspirates yield adequate CD34(+) cells but can result in relative delays in engraftment. Granulocyte colony-stimulating factor (G-CSF)-primed BM HSPCs may facilitate faster engraftment while minimizing graft-versus-host disease in certain patient subsets...

The complex pathophysiology of progressive chronic kidney disease (CKD) and the development of mineral and bone disorder, abbreviated as CKD-MBD, is of vital importance to a pediatric patient. Paricalcitol, the 19 nor-1,25(OH)2D2 analogue was shown to be effective and safe in the treatment of secondary hyperparathyroidism (SHPT) in adults almost two decades ago. It also significantly improved survival in dialysis patients compared to the standard calcitriol. The successful treatment of CKD-MBD in children is essential if they are to grow and survive into adulthood...
