Filter by:Delirium is a frequent and severe condition, especially in old adults. Its occurrence is due to a drug in 30% of cases. In 2009, the French national health authority (Haute Autorité de Santé) mentioned proton pump inhibitors (PPIs) among the drugs causing delirium. Most reports of delirium associated with PPI use in the literature are due to severe hyponatremia due to syndrome of inappropriate antidiuretic hormone secretion. However, a few case reports have described the occurrence of delirium PPI without hyponatremia related to PPI use. In 2016, a prospective observational study including 675 old adults found an association between PPI use and the occurrence of delirium. Evidence linking delirium and PPI use is thus scarce. By using data from the pharmacovigilance database of the World Health Organization (WHO), the investigators aim to describe the characteristics of delirium reports in which PPI were suspected to be involved, and to evaluate the association between PPI use and delirium, and the impact of hyponatremia in this association by performing a disproportionality analysis.
The aim of this study is to further analyse the dataset of the Hyponatremia Registry, a multicenter, prospective, observational study conducted between September 2020 and February 2013 in the United States of America and the European Union. The primary interest was to provide evidence to investigators' hypothesis that baseline sodium levels are a predominant factor determining the rapidity of sodium increase irrespective of the given treatment. Further investigators aimed to identify other independent predictors of the increase of plasma sodium upon treatment.
Considering the physiological changes in fluid and electrolyte balance and providing proper support are one of the important aspects of neonatal intensive care. Maintenance intravenous fluids are designed to maintain homeostasis when a patient is unable to uptake required water, electrolytes, and energy. Hypotonic fluids are still the most commonly prescribed IV fluids for pediatric hospitalized patients. However, previous studies, including children older than one month of age revealed that traditionally used hypotonic fluids may lead to hyponatremia. Because of the absence of evidence-based data, there is currently no clear consensus on the optimal composition of maintenance intravenous fluid therapy in newborns, leading to wide practice variation. The National Clinical Guideline Center (NICE) 2015 recommends the use of isotonic fluids in term newborn infants and some newborn centers has begun to use isotonic fluids since guidelines recommendations. Since the publication of the NICE guideline, no studies have addressed this topic. In this prospective, observational , multicentric study, conventional hypotonic fluids containing sodium chloride (NaCl) < 130 mmol/L compared with isotonic fluids (containing NaCl between 131-154 mmol/L) in terms of the risk of hyponatremia, hypernatremia, plasma sodium (pNa) level change, treatment morbidities, hospitalization duration and mortality.
Retrospective study that analyzes the changes in serum creatinine as a tool to correctly classify the volemic status volemic status (euvolemia vs hypovolemia) of the patients with hyponatremia.
SYSTEMIC INFLAMMATION HAS BEEN ASSOCIATED WITH SEVERE COVID-19. HYPONATREMIA CAN RESULT FROM INFLAMMATION DUE TO NON-OSMOTIC STIMULI FOR VASOPRESSIN PRODUCTION. IN THIS PROSPECTIVE COHORT STUDY WE ANALIZED DATA FROM PATIENTS WITH COVID-19 AND THE ASOCIATION WITH HYPONATREMIA AND CLINICAL OUTCOMES.
In this retrospective study, the investigators determined the frequency of hyponatremia in small cell lung cancer and the prognosis. 126 (27%) of 466 patients were hyponatremic. Hyponatremia could not be corrected in 50.8% (n=64) of hyponatremic patients. Survival was found to be better in the group of whom hyponatremia was corrected.
Hyponatremia is the most frequent electrolyte disorder encountered in clinical practice. The patient approach, however, is still problematic, above all because hyponatremia is a manifestation correlated to various pathological conditions, with complex etiopathogenesis. Even though some algorithms have been proposed to correctly assess hyponatremia subtype classification and patient volume status, there is no single parameter that has proven to be able alone to perfectly achieve this result.
Acute water load test has been using to diagnose renal ability to excrete water for decades. Latest recommendations for the diagnosis of hyponatremia do not recommend performing such a test. The investigators aim at, retrospectively, study the value of acute water load test in patients suffering from a syndrome of inappropriate antidiuresis.
Context. The relevance of hyponatremia has been acknowledged by guidelines from the United States of America (2013) and Europe (2014). However, treatment recommendations differ due to limited evidence. Objective. In hyponatremia following pituitary surgery - caused by the syndrome of inappropriate antidiuretic hormone (SIADH) secretion - the investigators compared fluid restriction with the pharmacological increase of water excretion by blocking the vasopressin 2 receptors with tolvaptan at a low and moderate dose. Design. Prospective observational study. Setting. Neurosurgical Department of a University hospital with more 200 pituitary procedures per year. Patients. Participants undergoing surgery for sellar lesions and developing a serum sodium below 135 mmol/L. The diagnosis of SIADH was established by eu- or hypervolemia (daily measurement of body weight and fluid balance daily), an inappropriately concentrated urine (specific gravity) and exclusion of a cortico- and thyreotropic insufficiency. Intervention. Participants were treated with fluid restriction (n=38) or tolvaptan at 3.75 (n=38) or 7.5 mg (n=48) orally. Main Outcome Measures. Treatment efficacy was assessed by the duration of hyponatremia, sodium nadir and length of hospitalization. Safety was established by an increment serum sodium below 10 mmol/L per day and exclusion of side effects.
Hyponatremia is a common complication among preterm infants, renal losses of sodium contribute to the development of hyponatremia in preterm newborns. Sodium imbalances impact in newborns outcome. There is controversy about the time of initiation and the requirements of sodium in premature infants. Hypothesis: early (24 hours of life) sodium supplementation (5mEq/kg/day) prevents the develop of hyponatremia in preterm infants.
