Active clinical trials for "Acidosis"

Cardiovascular disease (CVD) is the leading cause of death in patients with chronic kidney disease (CKD) and large artery damage is a major factor that contributes to death. Metabolic acidosis is a common complication of CKD resulting from an inability of the diseased kidney to excrete the daily dietary acid load and it is associated with all-cause mortality in patients with CKD. However, the effect of treatment of metabolic acidosis with oral sodium bicarbonate on endothelial dysfunction and arterial stiffness in patients with CKD has not been evaluated. The investigators propose a prospective, randomized, controlled, open-label 14-week crossover pilot study examining the effect of treatment of metabolic acidosis with oral sodium bicarbonate on vascular endothelial function in 20 patients with CKD stage IV with metabolic acidosis.

The overall objective of this drug trial is to determine whether the treatment of acute hyperammonemia with N-carbamyl-L-glutamate (NCG, Carglumic acid) in propionic acidemia (PA), methylmalonic acidemia (MMA), late-onset CPS1 deficiency (CPSD) and late-onset Ornithine transcarbamylase deficiency (OTCD) accelerates the resolution of hyperammonemia efficiently and safely. The primary goal is to determine if the study drug (NCG) efficiently reduces ammonia levels following a hyperammonemia episode(s). Secondly, the investigators want to know if treatment with this study drug (NCG) efficiently improves neurologic function, reduces plasma glutamine levels and lessens the duration of hospitalization after each episode of hyperammonemia.

This study evaluates the effect of oral sodium bicarbonate treatment on the intrarenal renin-angiotensin-system in adult patients with a metabolic acidosis and chronic kidney disease. This treatment is compared to sodium chloride treatment, which serves as control for increased sodium-intake and no treatment, which serves as time-control.

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.

The administration of intravenous fluids is ubiquitous in the care of the critically ill. Commonly available isotonic crystalloid solutions contain a broad spectrum electrolyte compositions including a range chloride concentrations. Recent prospective, randomized trials have shown improved patient outcomes with the use of balanced crystalloids compared to saline. There have not been large randomized studies comparing acetate buffered balanced crystalloids to non-acetate buffered balanced crystalloids in the critically ill. BASE will be a pilot study for a large, cluster-randomized, multiple-crossover trial enrolling critically ill patients from the Medical ICU at Vanderbilt University from June 2018 until January 2019. The primary endpoint will be plasma bicarbonate concentration between Intensive Care Unit admission and hospital discharge.

Kidney disease is a common medical condition. Individuals with kidney disease develop a build-up of acid in their blood. This acid can affect their muscles, bones, glucose metabolism and kidneys. The investigators will test alkali treatment, to treat acid build-up, in a randomized placebo-controlled clinical trial to evaluate effects on muscles, bones, glucose metabolism and kidney.

The objective of this study is to evaluate the effects of 'high' versus 'low' volume intraoperative fluid administration (Ringer Lactate, RL) on intra- and postoperative parameters, in obese patients undergoing laparoscopic bariatric surgery (i.e., gastric bypass), in order to establish evidence-based data for perioperative fluid management in this patient population. Based on their experience as well as several reports in the literature, the investigators hypothesized that a restrictive approach to intraoperative hydration will reduce the incidence of postoperative complications and the recovery time of gastrointestinal (GI) function, and shorten hospital stay.

Acidosis (accumulation of acid in the body) may be an underrecognized problem in patients after renal transplantation. It may have consequences on physical performance due to negative effects on bone and muscle metabolism. Therefore, the purpose of this study is to determine the status of physical capacity and bone structure in renal transplant patients with metabolic acidosis to study the effect of substituting base equivalents (citrate) on acid/base status of renal transplant patients with acidosis to compare the status of physical capacity and bone structure in renal transplant patients with metabolic acidosis before and after substitution with citrate

The purpose of this study is to assesses the efficacy of oral supplementation with glutamine over three months on several amino acids and lactate concentration measured in cerebrospinal fluid and cerebral lactate measured by magnetic resonance spectroscopy.

An acid-base imbalance, called metabolic acidosis (acid-base disorder lasting from several minutes to several days, caused by a decrease in serum bicarbonate ion (HCO3) concentration), is often observed in critically ill patients with various underlying diseases. Metabolic acidosis has a negative impact on the cardiovascular, respiratory, digestive, nervous, excretory, hematological, endocrine, musculoskeletal and immune systems and is associated with unfavourable outcomes. Reamberin® is a solution of disubstituted sodium salt of succinic acid, which has an alkaline reaction and succinate is capable to integrate into the Krebs cycle and restore energy metabolism in the cell. The aim of the present study is to evaluate the efficacy and safety of meglumine sodium succinate at a dose of 500 to 3000 ml in critically ill patients with metabolic acidosis and choose the optimal volume of its solution for the correction of metabolic acidosis in critically ill patients.
