Filter by:Researchers are trying to determine which dialysis solution, low bicarbonate fluid (22 mmol/L) or high bicarbonate fluid (32 mmol/L), is better in subjects with acute kidney injury (acute kidney failure) and metabolic acidosis that are admitted to the intensive care unit and require continuous renal replacement therapy (also known as continuous dialysis).
The purpose of this study is to evaluate the effect of TRC101 on the progression of chronic kidney disease (CKD) and to evaluate the safety profile of TRC101 in CKD patients with metabolic acidosis.
Metabolic acidosis is associated with vascular endothelial dysfunction and is a common complication in patients who have received a kidney transplant. Kidney transplant recipients (KTR) with lower serum bicarbonate levels, even within the normal range, have an increased risk of graft loss and mortality. The investigators propose a prospective, double-blind, randomized, placebo-controlled, 18-week crossover pilot study to examine the effects of sodium bicarbonate on vascular endothelial function, graft function, and cognitive function in 20 KTR patients.
This study is a 40-week, blinded, placebo-controlled extension of Study TRCA-301 (NCT03317444). Eligible subjects who complete the 12-week treatment period in Study TRCA-301 have the option to participate in this extension study evaluating the long-term safety and durability of effect of TRC101 in subjects with non-dialysis dependent chronic kidney disease and metabolic acidosis. Eligible subjects will be treated with TRC101 or placebo once daily (QD) on an out-patient basis for the subsequent 40 weeks. Subjects will continue to receive the same blinded treatment (TRC101 or placebo) that they received in Study TRCA-301.
Effect of oral sodium bicarbonate therapy on renal tubular acidosis in epilepsy patients taking topiramate.
This is a multicenter, double-blind, placebo-controlled, parallel-design study. The study will enroll approximately 210 adult male and female subjects with stage 3 or 4 chronic kidney disease and metabolic acidosis. The study dosing (TRC101 or placebo) will continue for 12 weeks once daily. The maximum study duration is anticipated to be up to 16 weeks.
Metabolic acidosis recovers a wide range of diseases in which an oral alkalinization could be useful. This therapeutic intervention has been said to increase extracellular volume leading to rising blood pressure. No prospective data has been published in clinical routine. Here, investigators propose to follow patients in which an oral alkalinization is indicated: blood pressure, body weight, and a clinical evaluation of the extracellular compartment will be performed at the beginning and during the follow-up of participants. The principal criterion of evaluation will be the variation in the extracellular compartment.
Low serum bicarbonate levels, even within the normal laboratory range, are strongly associated with increased risks of hypertension, endothelial dysfunction, cardiovascular disease and death. The current proposal will investigate whether bicarbonate administration in patients with chronic kidney disease (CKD) will improve the health and function of arteries and reduce the size of the left ventricle of the heart. Overall, the proposed research will provide important new scientific evidence upon which physicians can base recommendations to patients with CKD to decrease the risk of developing cardiovascular diseases.
Metabolic acidosis is a common complication that patients experience in the early postoperative period following cardiac surgery. Increasingly, the composition and volume of intravenous fluids administered during surgery have been implicated in the development of postoperative acidosis. Intraoperative Cell Salvage (ICS), an autologous blood transfusion technique employed by Cardiac/Perfusion Units to minimize blood loss during surgery, involves the infusion of of one such fluid, 0.9% sodium chloride. The rapid infusion of large volumes of 0.9% sodium chloride has previously been linked with the development of hyperchloraemic acidosis. It was therefore hypothesized that the volume of mechanically salvaged of red blood cells re-infused into patients undergoing heart surgery contributes to the acidosis that occurs in the early postoperative period. To test this, the investigators have designed an observational cohort study to check for correlation between the volume of cell salvaged blood infused during surgery and the severity of postoperative acidosis (which will be assessed using data from routine arterial blood gas samples).
The purpose of the present study is to compare the adjunct treatment of metabolic or mixed severe acidosis in the critically ill using Sodium Bicarbonate as a buffer to increase the plasma pH vs no buffering therapy. The study is a randomized multiple center clinical trial with the outcome as a primary endpoint.
