...Wenyan Yu; Feng Zhuang; Shuai Ma; Qichen Fan; Mingli Zhu; Feng Ding Background: It has been confirmed that regional citrate anticoagulation (RCA) plays an effective role in extracorporeal anticoagulation. The current trial-and-error calcium supplementation approach, with intensive monitoring...

...) assay overestimates, whereas the bromcresol purple (BCP) assay underestimates albumin concentration. Since corrected calcium concentrations depend on albumin, the albumin assay may have implications for the management of bone mineral disorders. Methods: A subset of patients from CONTRAST, a cohort...

...Akishi Momose; Yasuo Shiraiwa; Satoshi Narita; Tomomi Kusumi; Shoko Goto; Koichiro Sera Background/Aims: In our earlier studies, we reported high concentrations of intra- and extracellular calcium ions (Ca 2+ ) in the deeper epidermis of patients with chronic kidney disease (CKD) and associated...

... consisted of 382 patients submitted to a Nephrology Unit for evaluation of advanced CKD in a tertiary hospital from Gran Canaria during 3 years. Associations between anemia and serum levels of calcium (albumin-corrected), phosphorus, PTH, 25-hydroxivitamin D (25(OH)D 3 ) and alkaline phosphatase were...

... lead to supersaturation of lithogens in the renal collecting system. The protective mechanisms that prevent the rise in the concentration of the lithogenic substances in urine, such as calcium phosphate, are explored. Methods: Urine samples were collected from 26 subjects every 2-3 h during daylight...

Olgaard The effects of intravenous administration of 1 α-hydroxycholecalciferol [lα(OH)D 3 ] in combination with CaCO 3 and ‘low-calcium dialysis’ (1.25 mmol/l) on plasma (p) parathyroid hormone (PTH) and biochemical bone markers...

... of l,25(OH) 2 vitamin D for 10 days. This protocol reproducibly produced markedly increased urinary calcium excretion (mean calciumxreatinine ratio 0.5). Despite this, no subject developed hematuria as seen by dipstick urinalysis or by alteration in erythrocyte Addis counts (mean counts 1.02 × 10 6 /12...

... compared the levels of serum intact parathyroid hormone (PTH) and the suppressibility of PTH by intravenous calcium infusion before and after 12 weeks of rHuEPO treatment in 8 HD patients with secondary HPT. The suppressibility of PTH by calcium infusion in HD patients was also compared with that of normal...

... increased in CRF rats compared to those of sham-operated rats when both groups of rats were fed with normal P (0.6%) diet. These changes were not accompanied by any detectable changes of serum concentrations of calcium (Ca), inorganic phosphate (Pi) or calcitriol. In contrast, such evidence of 2°HPT...

... hemodynamics. The exact mechanism of action of a HP meal on renal hemodynamics is not clear, but it appears that one mechanism by which a HP meal may alter renal hemodynamics is by altered calcium homeostasis. 10 10 1993 17 12 2008 © 1994 S. Karger AG, Basel 1994 Copyright / Drug Dosage...

...Anthony W. Nestel; Anthony M. Meyers; Janice Paiker; Halina B. Rollin It is well known that Al absorption is markedly enhanced by citrate. The aim of the study was to document whether low-dose citrate ingestion (4 g/day) contained in a well-known effervescent calcium supplement was sufficient...

... was not dependent on the increased production of autocrine matrix-stimulatory mediators by SHR MC. Changes of cytosolic free calcium – [Ca 2+ ] i -could not be correlated with the enhanced responsiveness of SHR MC to the tested growth factors. The described differences of cellular functions between SHR and WKY MC...

... in the erythrocytes of uraemic patients treated with recombinant human erythropoietin (rhEPO). Erythrocyte deformability is, at least partly, determined by the intracellular concentration of free calcium ions. Six patients with renal anaemia (initial haemoglobin 95 ± 11 g/l) were treated with rhEPO. They were...

Sørensen; Lars Hyldstrup; Ib Transbøl The objective of this study was to elucidate the effect of oral calcium supplement upon the severity of secondary hyperparathyroidism and hyperphosphatemia in patients undergoing hemodialysis. Twenty...

...H. Saha; J. Mustonen; K. Pietilä; A. Pasternack We studied serum concentrations of calcium, phosphate, intact parathyroid hormone (PTH) and vitamin D 3 metabolites in 41 patients with nephropathia epidemica. Thirty-four of the 41 patients had a mild to moderate, mostly nonoliguric acute renal...

...Makoto Nakamura; Hiromichi Suzuki; Hiroshi Yamakawa; Takao Saruta We measured blood pressure, platelet cytosolic calcium concentration ([Ca 2+ ] i ) and vasoactive hormones in 20 anuric normotensive patients on chronic hemodialysis (HD) to clarify the role of cytosolic calcium in regulation...

Among the latter, periarticular tumoral calcifications (TC) represent massive, multiloculated calcium-phosphate deposits. The aim...
