Abstract:
The invention provides a source of sodium thiosulfate via the dialysate used to cleanse the blood of toxic and metabolic waste in patients undergoing hemodialysis, peritoneal dialysis, or gastro-intestinal dialysis for treatment of end-state or near end-stage chronic renal disease. In the method of the invention, dialysis solution components contain therapeutic amounts of sodium thiosulfate, which when fully reconstituted for use as a single solution, deliver 20-130 mg/dl of dialysate.
Abstract:
The invention relates to a container having a wall structure comprising a polymer material including an acid diffusion barrier. The invention also relates to a use of a cycloolefin polymer, COP, and/or a cycloolefin copolymer, COC, as an acid diffusion barrier polymer in a container for an acid. The invention further relates to a use of such a container and to a system for providing a medical solution comprising at least one container according to the invention. Finally the invention relates to a method for treatment by means of a container according to the invention.
Abstract:
The dose of dialysis in terms of urea clearance is marginal in many hemodialysis patients, and metabolic acidosis as determined by the pre-dialysis serum HCO3 level is common. A dialysate that included citric acid rather than acetic acid as acidifying agent provides superior performance properties. Citrate-containing dialysate was used exclusively in 22 hemodialysis patients. Initially, only 8 of the 22 patients had a pre-dialysis serum HCO3>23mEq/L (lower limit of normal), however, after 12 weeks of dialysis using the citrate-containing dialysate, the serum HCO3 normalized in 15 patients (p=0.0001, Chi-square). Dialysis variables were kept constant in 19 of the patients, who also used and reused the same dialyzer model throughout. In these patients, the initial average urea reduction ratio (URR) was 68.5+/-5.9%, and after treatment with the citrate dialysate disclosed herein, this ratio had increased to 73+/-5.3% (p
Abstract:
The present invention provides a liposomal composition, method of using a liposomal composition, and devices and modes of operation of the devices and of the compositions, and kits related thereto. The invention provides for the reverse transport of cholesterol from peripheral tissues to the liver in a warm blooded mammal while controlling plasma atherogenic lipoprotein concentrations, including LDL concentrations. The method and mode of operation of the devices includes the step of administering an effective amount of a multiplicity of acceptors comprised of phospholipids substantially free of sterol. The method optionally includes the step of periodically assaying atherogenic lipoprotein concentrations with an assay during the treatment period to assess atherogenic lipoprotein concentrations and obtain an atherogenic lipoprotein profile, and adjusting the administration in response to said profile. The large liposomes are dimensioned larger than fenestrations of an endothelial layer lining hepatic sinusoids in the liver so that the liposomes are too large to readily penetrate the fenestrations of one variant. The therapeutically effective amounts are in the range of about 10 mg to about 1600 mg phospholipid per kg body weight per dose. A pharmaceutical composition and related kit for mobilizing peripheral cholesterol and sphingomyelin that enters the liver of a subject consisting essentially of liposomes of a size and shape larger than fenestrations of an endothelial layer lining hepatic sinusoids in the liver is also provided. The invention also provides for control of cholesterol related genes and other compounds.
