Filter by:We aimed to investigate the role of bioimpedance spectroscopy for the diagnosis of hyponatremia
Hypothesis: Tolvaptan will improve cognitive function, brain edema and health-related quality of life in cirrhotic patients with hyponatremia
This study is designed to determine the causes of low sodium (salt) in the body fluids outside the cells for patients who have received a kidney transplant at the Mayo Clinic of Florida. The investigators will look at data collected on previous transplant patients at the Mayo Clinic to determine if the low sodium levels could be related to factors occurring in the course of surgery. The investigators hypothesize that the intravenous fluid used in the surgery, which is about half the concentration of normal saline, could contribute to the low sodium levels.
Background: Hypo- and hypernatremia are common in hospitalized patients. The differential diagnosis of dysnatremia is challenging. Osmotically inadequate secretion of antidiuretic hormone (ADH) is the predominant mechanism in most dysnatremic disorders. ADH measurement is cumbersome. It is derived from a larger precursor peptide along with copeptin, which is a more stable peptide directly mirroring the production of ADH. Objective: To evaluate the additional value of copeptin to improve a currently used algorithm in the differential diagnosis of (A) severe hypoosmolar hypo- and (B) severe hypernatremia. Design: Prospective observational study.
The purpose of this study is to create an institutional and population-based registry of Hyponatremia with a prospective survey based on epidemiological data, risk factors, diagnosis, prognosis, treatment, monitoring and survival. This study will also describe the occurrence of hyponatremia in the population of HIBA in the Central Hospital, as well as the characteristics of clinical presentation, evolution and predisposing factors of hyponatremia.
The purpose of this study is to detect if there are any differences in the coding region of SLC12A3 gene in individuals who have had hyponatremia associated to the use of thiazides, and those thiazides consumers without hyponatremia that have demonstrated good tolerance to the drug.
The aim of this study is to evaluate the different types of osmotic dysregulation in patients with Syndrome of Inappropriate ADH (SIADH) and, hence, to analyze the pathophysiology of SIADH. These types will be characterized by measurement of AVP and copeptin while performing an osmotic stimulation with infusion of hypertonic saline.
The primary objective of this study is to compare the mean serum sodium after 48 hours of therapy with either 0.45% NaCl/dextrose 5% or 0.9% NaCl/dextrose 5%, in critically ill children requiring IV maintenance fluid administration.
Objective: To compare the incidence of peri-colonoscopy hyponatremia associated with PEG 3350 + sports drink (PEG-SD) versus PEG 3350-electrolyte solution + sodium sulfate + sodium ascorbate and ascorbic acid (PEG-ELS). Hypothesis: As compared to PEG-SD, hyponatremia occurs significantly less often with PEG-ELS.
The primary objective of this study is to compare the blood sodium level after 12 hours following the initiation of therapy with either 0.3% NaCl/dextrose 5% or 0.45% NaCl/dextrose 5%, in postsurgical hospitalized children requiring maintenance IV fluid administration.
