View clinical trials related to Hyponatremia.
Filter by: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.
The aim of this epidemiological study is to characterize the neuropsychological and motoric performance in patients with hyponatremia. Newer studies revealed an association between mild hyponatremia and unstable walking, frequency of falls and risk of a fracture, questioning the paradigm of an "asymptomatic" hyponatremia. Until now, there is no known detailed investigation and characterisation of the cognitive and motoric performance or limitation by this disorder. Therefore this study will investigate patients with hyponatremia on the basis of neuropsychological and neurological tests.
This is a phase IV, open-label, prospective cohort study for 7 days.The recommended starting dose of tolvaptan is 15 mg daily orally. The dose may be titrated on the next day at 15 mg intervals up to 60 mg daily according to the serum sodium level response.Serum sodium level, change in sodium level from baseline, quality of life (EQ-5D-3L), change in body weight, edema, renal function, mortality and liver-related complications on day 7 and day 30 to evaluate the efficacy of tolvaptan in cirrhotic patients with hyponatremia.
We aimed to investigate the role of bioimpedance spectroscopy for the diagnosis of hyponatremia
The purpose of this study is to determine the effect of fluid restriction and the neurohormonal mechanisms in the development of hyponatremia in patients with congestive heart failure and hyponatremia. The hypothesis is that strict fluid restriction leads to a larger increase in plasma sodium than standard treatment in patients with decompensated heart failure associated with hyponatremia. A secondary hypothesis is that the neurohormonal change is greater in patients treated with strict fluid restriction versus standard treatment.
The purpose of the study is to investigate the efficacy and safety for the management of hyponatremia and ascites in patients with liver 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.
Hypothesis: Tolvaptan will improve cognitive function, brain edema and health-related quality of life in cirrhotic patients with hyponatremia
This study is to evaluate the efficacy of a 2-week course of tolvaptan in improving serum sodium and the excretion of extracellular fluid in liver cirrhotic patients with ascites and hyponatremia
The aim of this study is to identify factors associated with hyponatremia among patients hospitalized in the internal medicine ward. Consequtive patients hospitalized because of hyponatremia will be recruited. Follow up will include clinical factors such as background diseases, complete drug history, blood tests including Biochemistry tests (Sodium, renal function), endocrinological evaluation, thyroid function tests, cortisol,urinary sodium on addmition. One month following discharge follow up Sodium level will be taken.
