Multi-center Study to Investigate the Effects of Citrasate® on Heparin N Requirements During Hemodialysis Treatment

09:01 EDT 21st May 2013 | BioPortfolio

Summary

The purpose of this study is to determine whether the use of Citrasate®, citric acid dialysate enables the reduction of the heparin N (anticoagulant) dose in patients undergoing hemodialysis.

Description

During hemodialysis, waste products are removed from the blood by diffusion across the dialyzer membrane into an electrolyte solution known as dialysate. Dialysate is produced from acid concentrate, bicarbonate solution and water using a three stream proportioning system that mixes the acid concentrate, bicarbonate and water to produce the final dialysate. Patients are typically anticoagulated with heparin during dialysis to prevent blood from clotting in the extracorpoeial circuit. Heparin use is associated with significant risks including the possibility of bleeding, heparin induced thrombocytopenia (HIT) and contamination. For these reasons, the possibility of reducing heparin dose while maintaining HD adequacy is clinically attractive. Citrasate® is an FDA approved acid concentrate that contains citric acid (citrate) rather than acetic acid (acetate) which is traditionally used in acid concentrate. Citrate in higher concentrations is also a known anticoagulant. We are therefore conducting this study to determine whether the use of Citrasate, citric acid dialysate enables the reduction of the heparin requirements in patients undergoing hemodialysis.

Medical and Biotech [MESH] Definitions

Renal Dialysis

Therapy for the insufficient cleansing of the BLOOD by the kidneys based on dialysis and including hemodialysis, PERITONEAL DIALYSIS, and HEMODIAFILTRATION.

Membranes, Artificial

Artificially produced membranes, such as semipermeable membranes used in artificial kidney dialysis (RENAL DIALYSIS), monomolecular and bimolecular membranes used as models to simulate biological CELL MEMBRANES. These membranes are also used in the process of GUIDED TISSUE REGENERATION.

Renal Insufficiency

Conditions in which the KIDNEYS perform below the normal level in the ability to remove wastes, concentrate URINE, and maintain ELECTROLYTE BALANCE; BLOOD PRESSURE; and CALCIUM metabolism. Renal insufficiency can be classified by the degree of kidney damage (as measured by the level of PROTEINURIA) and reduction in GLOMERULAR FILTRATION RATE. The most severe form is KIDNEY FAILURE. Renal function may deteriorate slowly (RENAL INSUFFICIENCY, CHRONIC) or precipitously (RENAL INSUFFICIENCY, ACUTE).

Peritoneal Dialysis, Continuous Ambulatory

Portable peritoneal dialysis using the continuous (24 hours a day, 7 days a week) presence of peritoneal dialysis solution in the peritoneal cavity except for periods of drainage and instillation of fresh solution.

Peritoneal Dialysis

Dialysis fluid being introduced into and removed from the peritoneal cavity as either a continuous or an intermittent procedure.
