Description

WO 2010/005961 PCT/US2009/049800 NUTRITIVE COMPOSITIONS AND METHODS OF USING SAME FIELD OF THE INVENTION The invention pertains to nutrition supplement compositions for patients receiving 5 dialysis treatment and methods of using the nutrition supplement compositions. The nutrition supplement compositions include reduced levels of carbohydrates and lower volume to reduce complications in patients who are diabetic or suffer from other glucose management related pathologies, or patients who require strict fluid management. 10 BACKGROUND OF THE INVENTION Severe malnutrition remains a problem for patients receiving maintenance hemodialysis (MHD). Dialysis patients often have poor appetites and low energy. This malnutrition is reflected in low serum albumin concentrations, a strong predictor of increased morbidity and mortality. (Moore and Lindenfield, Support Line 29(5):7-16 (Oct. 2007)). 15 Patients are often treated using diet liberalization, oral supplements and enteral feeding. When these methods are not effective intradialytic parenteral nutrition (IDPN) may be utilized for more aggressive nutrition repletion efforts. IDPN is infused during the hemodialysis procedure. IDPN has been used for decades and has resulted in weight gain and improved protein levels in patients. (U.S. Publication 20 No. 2005/0148647). The typical IDPN treatment delivers 4-6 mg/kg/minute of glucose for patients in need of carbohydrate control and 6-8 mg/kg/minute for patients who do not need carbohydrate control. Blood glucose must be monitored to avoid problems associated with insulin resistance, hyperglycemia and hypoglycemia. In some cases, insulin is also administered either in the IDPN solution or more typically separately administered 25 subcutaneously to modulate blood glucose levels. IDPN generally contains 1.2-1.4 g/kg of amino acids. However, these amounts can be lowered for patients who do not tolerate protein well. Monitoring of serum bicarbonate and carbon dioxide levels must be monitored to check for acidosis caused by administration of amino acids. Lipids are provided in IDPN at a rate between 4 mg/kg/minute and 12-12.5 g/hour depending on tolerance of the lipids by the 30 patient. Generally, these lipids are emulsions of purified vegetable oil from soybean (Intraliipid@ from Kabi Vitrum or Travamulsion@ from Travenol) or safflower oil (Liposyn@ from Abbott). (Powers, Contemporary Dialysis and Nephrology:29-31 (Feb. 1990).

WO 2010/005961 PCT/US2009/049800 IDPN is usually administered in one liter of solution, and occasionally micronutrients, like vitamins and minerals are co-administered in or with IDPN. IDPN has proved effective in decreasing morbidity and mortality in MHD patients, leads to increased levels of serum albumin and creatine levels, and increased body weight. (Moore and Celano, Nutrition in 5 Clinical Practice, 20(2):202-212 (2005)). Hypoglycemia is another potential dangerous result of the administration of insulin during IDPN with symptoms of nervousness, sweating, intense hunger, trembling, weakness, palpitations, and trouble speaking. Problems associated with IDPN include hyperglycemia, complications in patients with insulin resistance or other problems associated with glucose management, as well as 10 complications in patients who require strict fluid management. The glucose concentrations administered with IDPN can cause hyperglycemia and hypoglycemia in some patients. The administration of insulin can sometimes successfully treat this hyperglycemia, but some patients demonstrate insulin resistance, and may not respond to insulin treatment. (Goldstein and Strom, Journal ofRenal Nutrition 1(l):9-22 (Jan. 1991)). Hyperglycemia is a major 15 barrier to effective nutrition support even outside the context of hemodialysis. Many studies report associations between hyperglycemia and increased morbidity and mortality. (McCowen and Bistrian, Nutrition in Clinical Practice, 19(3):235-244 (Jun. 2004)). Moreover, the amount of fluid in typical IDPN treatment is a barrier to use in patients with strict fluid management. Thus, a need exists for an improved IDPN composition for 20 administration to patients that diminishes hyperglycemia associated with IDPN administration and decreases the need for the administration of insulin with IDPN. Moreover, a need exists for a lower volume IDPN dosage form. SUMMARY OF THE INVENTION 25 The invention provides intradialytic parenteral nutrition (IDPN) solutions with low carbohydrate content and low volume. The IDPN solutions of the invention are effective in the treatment of malnutrition in patients receiving dialysis treatment. These solutions also reduce the need for insulin administration when administered to patients undergoing maintenance hemodialysis (MHD) patients. Moreover, patients with metabolic conditions 30 that impair their glucose tolerance and metabolism would also benefit from the IDPN solutions of the invention. Also, patients with strict fluid management would benefit from the IDPN solutions of the invention. The IDPN solutions of the invention also include amino acids and, optionally, lipids and/or micronutrients such as vitamins, trace elements and/or minerals. In certain preferred embodiments the IDPN solutions are lipid free. In other WO 2010/005961 PCT/US2009/049800 preferred embodiments, the IDPN solutions of the invention are kept in containers for administration to patients, such as bags appropriate for parenteral administration. In one embodiment, each bag contains one dose of IDPN for a patient. In other embodiments, these doses are supplemented with pharmaceuticals, such as insulin. These doses are often 5 administered subcutaneously using a separate administration system. DETAILED DESCRIPTION The invention provides intradialytic parenteral nutrition (IDPN) solutions with low carbohydrate and low volume.

Preferably 5-20 units of insulin is added with one dose of IDPN. 25 Preferably, the IDPN solution of the invention is administered to dialysis patients who are suffering from malnutrition. A dialysis patient suffering from malnutrition can be identified by detecting evidence of protein or energy malnutrition and inadequate dietary protein intake, evidence of the inability to administer or tolerate adequate oral nutrition inclusive of supplements and tube feeding, and evidence that the combination or oral and/or 30 enteral intake when combined with IDPN will meet the patient's nutritional needs. Administration of the IDPN solution of the invention generally coincides with the start of hemodialysis on a patient. During IDPN solution administration the patient should be monitored for glucose tolerance, protein status and/or fat status. Glucose monitoring includes blood glucose level before, during and after IDPN administration and monitoring the patient WO 2010/005961 PCT/US2009/049800 for symptoms of hyper or hypoglycemia. The symptoms of hyperglycemia include nausea, thirst, headache, vomiting and weakness. The symptoms of hypoglycemia include headache, dizziness, tremors, cold sweat, confusion, and faintness. The presence of hyper or hypoglycemia can then be confirmed through blood sugar analysis, such as via a fingerstick 5 or arterial glucose level. To treat hyperglycemia, insulin is administered. To treat hypoglycemia the patient should receive 20-30 g of simple carbohydrates orally. Protein monitoring includes the monitoring of blood urea nitrogen (BUN) prior to dialysis and Kt/V which is a measure of dialysis adequacy. Fat monitoing includes a pre-dialysis triglyceride test prior to lipid infusion and then 10 another following first lipid infusion to ensure that the patient is clearing lipids from the bloodstream. Also, sodium, potassium, phosphorus and magnesium levels should be monitored for the presence of refeeding syndrome. Generally, the IDPN solution of the invention is administered through a port post dialyzer of the dialysis machine being used to perform hemodialysis on the patient. In a 15 preferred embodiment, the IDPN infusion is performed through the venous chamber of the dialysis machine. Examples of routes of parenteral administration include intravenous, intradermal, subcutaneous, and intraperitoneal administration. Any pharmaceutically acceptable carrier can be used in conjunction with the IDPN solution of the invention. The IDPN solution of the invention can be administered in the same manner prior art IDPN 20 solutions have been administered.
