Filter by:This study is examining how a dietary supplement called urea can be used to treat low blood sodium level. Low blood sodium level is a common problem and some studies show that many patients with low blood sodium level suffer from brain fog and/or loss of balance. Unfortunately, it is unknown at this point what the best treatment is for low blood sodium level. With this pilot research study, the investigators are hoping to learn more about whether urea is safe to take, whether patients can tolerate taking urea for several weeks, whether urea increases blood sodium level, and whether urea can help prevent the brain fog and/or loss of balance that some patients with low blood sodium level suffer from. The information obtained with this study is intended to be used to design a larger study in the future to get a definite answer whether urea is beneficial for patients with low blood sodium level.
In this study patients with hyponatremia, defined as a serum sodium < 126 mmol/L on admission to the hospital will be tested for muscular power by use of a hand grip dynamometer, for cognitive function by use of the Montreal-Cognitive-Assessment and gait stability by use of the Tinetti test. The tests will be performed on admission as well es after correction of hyponatremia.
This study will clarify the clinical usefulness of Tolvaptan therapy in patients with complicated acute decompensated heart failure and hyponatremia (low blood sodium).
Hyponatremia occurs frequently in patients with acute brain injury in the days to weeks following injury, and may contribute to adverse outcome. In addition, hyponatremia can aggravate neurologic dysfunction, complicate neurological assessments, and contribute to neurologic symptoms such as gait dysfunction that can impair efforts at mobilization and rehabilitation. Strict normonatremia (serum Na levels between 135 and 145 meq/dl) is the goal in most patients with acute brain injury. SIADH is the most frequent cause of hyponatremia in patients with neurological injury; however, treatment with fluid restriction is often difficult or contra-indicated, for example in patients with subarachnoid hemorrhage (SAH) where intravascular hypovolemia can trigger vasospasms. The aim of this project is to test Tolvaptan, an ADH antagonist, as a treatment in selected patients with acute brain injury who have developed SIADH.
The objective is to evaluate the efficacy and safety on the tolvaptan for increasing serum Na levels in patients with worsening heart failure and hyponatremia.
To assess the pharmacokinetic profile of tolvaptan in critically ill acute brain injury patients and to secondarily evaluate the clinical response and safety of tolvaptan in acute brain injured patients
The objective of this trial was to provide 6 months of safety follow-up for children and adolescents with dilutional (euvolemic or hypervolemic) hyponatremia who had previously participated in a tolvaptan hyponatremia trial and to assess the efficacy of tolvaptan in increasing serum sodium for those participants who received optional continuing tolvaptan treatment of variable duration (up to 6 months).
The purpose of this trial was to demonstrate that tolvaptan effectively and safely increases and maintains serum sodium concentrations in children and adolescent participants with euvolemic or hypervolemic hyponatremia.
Hyponatremia is a condition in which there is a low sodium level in the blood. Individuals with cirrhosis may develop low blood sodium as a complication of their liver disease. In these patients, the presence of low blood sodium may exacerbate other complications such as encephalopathy, resulting in confusion, drowsiness, or coma. It may also affect the ability of the body to fight infection. In certain cases, cirrhotic patients may be hospitalized for the treatment of their low blood sodium. The drug tolvaptan is currently FDA approved for the treatment of hyponatremia in patients with cirrhosis. Although it has been shown to increase the sodium level, the clinical trials that led to its approval did not otherwise assess clinical benefit of the drug. This study is designed to determine whether patients with cirrhosis derive a clinical benefit when they receive tolvaptan for the treatment of hyponatremia within 2 days of admission. Specifically, whether it is associated with shortened length of stay and improvement in other complications of cirrhosis.
Hyponatremia during labour has been associated with prolonged labour, and increased incidence of instrumental delivery and emergency caesarean section. Sodium influx in myometral cells are involved in contractility,and and influence of hyponatraemia on contractility can be suspected.
