OBJECTIVES Vascular calcification is a frequent complication in chronic haemodialysis patients and is associated with adverse outcomes. Serum calcium and phosphate levels and imbalances in calcification regulators are thought to contribute to the process. In this regard, the dialysate calcium concentration is a modifiable tool for modulating the risk of vascular calcification. We explored pre- ...

Plasma concentration of immunoreactive parathyroid hormone (IPTH) was measured in 18 patients who had been on a hemodialysis program for longer than 6 months. A negative correlation was found between the predialysis plasma concentration of IPTH and the mean concentration of calcium in the dialysate previously used: plasma concentrations of IPTH were higher in patients dialyzed against a calcium...

Many nephrologists feel threatened by the allegation that, in patients with chronic renal failure, treatment with calcium-based phosphate binders (calcium acetate and calcium carbonate) may induce coronary artery and cardiac calcification, thereby imposing a greater risk for death compared with sevelamer, a non-calcium-based binder. Acknowledging that drug manufacturers are not unaware of the m...

The crystallization of calcium phosphate nanoparticles in the presence carboxylates was characterized situ through simultaneous SAXS/WAXS using synchrotron light.

It has been close to a century since calcium phosphate materials were first used as bone graft substitutes. Numerous studies conducted in the last two decades have produced a wealth of information on the chemistry, in vitro properties, and biological characteristics of granular calcium phosphates and calcium phosphate cement biomaterials. An in depth analysis of several key areas of calcium pho...

BACKGROUND The effects of calcium compared with non-calcium-based phosphate binders on mortality, cardiovascular events and vascular calcification in patients with chronic kidney disease (CKD) are unknown. METHODS To address this question, we conducted a systematic review. We electronically searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and CINAHL. We identified 160 ...

BACKGROUND AND AIMS Lactulose fermentation by the intestinal microflora acidifies the gut contents, resulting in an increased resistance to colonisation by acid sensitive pathogens. The extent of fermentation should be controlled to prevent acid induced epithelial cell damage. Considering the buffering capacity of calcium phosphate and its intestinal cytoprotective effects, whether supplemental...

Seed induces and promotes the crystallization of calcium phosphate, and acts as carrier of the recovered phosphorus (P). In order to select suitable seed for P recovery from wastewater, three seeds including Apatite (AP), Juraperle (JP) and phosphate-modified Juraperle (M-JP) were tested and compared. Batch and fixed-bed column experiments of seeded crystallization of calcium phosphate were und...

From chronic kidney disease (CKD) Stage 4 onwards, phosphate binders are needed in many patients to prevent the development of hyperphosphataemia, which can result in disturbed bone and mineral metabolism, cardiovascular disease and secondary hyperparathyroidism. In this review, we re-examine the use of magnesium-containing phosphate binders for patients with CKD, particularly as their use circ...
