    摘要: Methods and compositions for detection of microbial contaminants in peritoneal dialysis solutions are provided. The methods and compositions employ modified bioburden testing and the detection of peptidoglycan. A novel cause of aseptic peritonitis is provided—aseptic peritonitis associated with gram positive microbial contamination of a dialysis solution. Peptidoglycan is a major component of a gram positive bacterial cell wall and thus can serve as a marker for gram positive bacteria. In this regard, testing for peptidoglycans can be utilized to effectively prevent peritonitis in patients that use the peritoneal dialysis solutions, such as peritoneal dialysis solutions that contain a glucose polymer including an icodextrin and the like.

    摘要: A peritoneal dialysis solution that is biochemically balanced to correct metabolic acidosis associated with chronic renal failure in a more physiological manner. The peritoneal dialysis solution has a physiological pH, e.g., pH of 7.0 to 7.4, and contains bicarbonate at a concentration that is found in normal blood. Additionally, the solution contains carbon dioxide at a partial pressure that is similar to partial pressure of carbon dioxide found in normal blood. The peritoneal dialysis solution also contains a weak acid with a pKa of less than 5.0.

    摘要: An improved peritoneal dialysis solution comprising an osmotic agent having at least one amino acid, and a method of administering same to a patient are provided. Pursuant to the present invention, the sodium concentration in the solution is decreased thus causing sodium to be transported from the circulation to the peritoneal cavity. This provides for an improved ultrafiltration profile that is, more volume over a longer period of time, for the same initial osmolality when compared to standard solutions. Also, the same ultrafiltration profile as standard solutions can be achieved with lower initial osmolalities.

    摘要: The present invention provides devices and methods for stabilizing bicarbonate-based solutions for peritoneal dialysis or hemofiltration. The bicarbonate-based solutions of the present invention are formulated and stored in at least two parts—an alkaline bicarbonate concentrate and an acidic concentrate. The alkaline bicarbonate concentrate is adjusted to have a pH of about 8.6 to 10.0. The acidic concentrate is adjusted to have a stable, acidic pH ranging from about 1.0 to 3.0. Upon mixing, although some variation in the pH of the mixed bicarbonate solution exists, the inventors have discovered that with the appropriate selection of the parameters of the concentrates, the pH of the mixed solution is always within an acceptable physiological range.
