Active clinical trials for "Water Intoxication"

The objective of this study is to determine if early high volume intravenous fluid administration (hyperhydration) may be effective in mitigating or preventing complications of shiga toxin-producing E. coli (STEC) infection in children and adolescents when compared with traditional approaches (conservative fluid management).

Greater muscular strength and power are relevant qualities for athletic success and decreased injury rate. It is known that dehydration impairs muscular strength and power, although the explanation for this association is not entirely clear. Besides morphological factors, strength production also depends on neural factors which in turn can be affected by dehydration. Some studies tested the effects of dehydration on neuromuscular function using electromyography (EMG) analysis. However, there is no consensus among those studies. Additionally, exercise may disturb water balance. This can further lead to dehydration if the athlete does not properly rehydrate. In this sense, the scientific evidence has identified people who are considered low drinkers that may be more susceptible to cellular shrinkage, potentially impairing health and performance. Thus, it would be expected that athletes regularly exposed to lower amounts of water intake would have beneficial effects in both performance and health if higher water ingestion was promoted, namely an improved neuromuscular function via enhanced cellular hydration. However, any potential benefit of increasing water intake on neuromuscular function is still to be determined using well-designed experimental studies and state-of-the-art methods. Lastly, there is no consensus regarding the diagnosis of dehydration in athletes. The identification of simple indices to measure dehydration in athletes is crucial as many may be inaccurately diagnosed.

This is an exploratory interventional study. The aim of the investigation is to identify and quantify contributing factors to local bioimpedance spectroscopy (BIS) measured by a wearable sensor patch, particularly the effect of fluid shifts caused by postural changes and lower body negative pressure (LBNP).

The investigation is a prospective cohort study, where two patient groups will be monitored by a wearable bioimpedance sensor during their scheduled treatment. The overall objective is to assess the bioimpedance sensor's ability to detect local and systemic fluid accumulation. Sub-investigation A will investigate the ability of the device to detect fluid accumulation in patients with stable chronic kidney disease undergoing regular and planned hemodialysis. Sub-investigation B will investigate the ability of the device to track hydration status in patients scheduled for an "intensive" dialysis treatment regime, due to severe overhydration.

Background: Data generated with the body composition monitor (BCM, Fresenius) show based on bioimpedance technology, that chronic fluid overload in hemodialysis patients is associated with poor survival. However, removing excess fluid by lowering dry weight can be accompanied by intradialytic and postdialytic complications. Here, we aim at testing the hypothesis that, in comparison to conventional hemodialysis, blood-volume monitored regulation of ultrafiltration and dialysate conductivity (UCR) and/or regulation of ultrafiltration and temperature (UTR) will decrease complications when ultrafiltration volumes are systematically increased in fluid overloaded hemodialysis patients. Methods/Design: BCM-measurements yield results on fluid overload (in liters), relative to extracellular water (ECW). In this prospective, multicenter, triple-arm, parallel group, cross-over, randomized, controlled clinical trial, we use BCM-measurements, routinely introduced in our 3 maintenance hemodialysis centers shortly prior to the start of the study, to recruit 60 hemodialysis patients with fluid overload (defined as ≥15% ECW). Patients are randomized 1:1:1 into UCR, UTR and conventional hemodialysis groups. BCM-determined, 'final' dry weight is set as -7% ECW postdialysis, and reached by reducing the previous dry weight, in steps of 0.1 kg per 10 kg body weight, during 12 hemodialysis sessions (one study phase). In case of intradialytic complications, dry weight reduction is decreased, according to a pre-specified algorithm. A comparison of intra- and postdialytic complications among study groups constitutes the primary endpoint. In addition, we will assess relative weight reduction, changes in residual renal function, quality of life measures, and predialysis levels of various laboratory parameters including C-reactive protein, troponin T, and N-terminal pro-B-type natriuretic peptide, before and after the first study phase (secondary outcome parameters). Discussion: Patients are not requested to revert to their initial degree of fluid overload after each study phase, Therefore, the cross-over design of the present study merely serves the purpose of secondary end-point evaluation, for example to determine patient choice of treatment modality. Previous studies on blood volume monitoring have yielded inconsistent results. Since we include only patients with BCM-determined fluid overload, we expect a benefit for all study participants, due to strict fluid management which decreases the mortality risk of hemodialysis patients.

This study's purpose is to determine whether tolvaptan can safely and effectively return the body's balance of sodium and water toward normal, and to characterize and quantify the potential clinical benefits of this treatment.

The objective of this study was to assess the effect of oral nutritional supplementation (ONS) combined with bioelectrical vector analysis (BIVA) on the nutritional and hydration status and the quality of life (QoL) in hemodialysis (HD) patients. Design and Methods: Thirty-two chronic HD patients were included in a 6-month randomized pilot study. Patients in SUPL group received a simultaneous intervention consisting of a personalized diet, 245 mL/d ONS and dry weight adjustment through BIVA. Patients in CON group received a personalized diet and dry weight adjustment by BIVA. Anthropometrical, biochemical, dietary, QoL, handgrip strength (HGS) and bioimpedance measurements were performed. Malnutrition Inflammation Score (MIS) was applied.

The purpose of this study is to investigate the effect of renal transplantation on fluid overload and its consequence on the severity of obstructive sleep apnea, in patients with end stage chronic kidney disease. It aims further to investigate the relationship between overhydration, nocturnal rostral fluid shift and the severity of sleep apnea.

The purpose of this research study is to evaluate the effects of a topical sodium bicarbonate lotion on physiological and psychological responses associated with hydration status and fluid balance in humans during passive heat stress. Currently, the ingestion of sodium has been an effective measure for improvements in fluid regulation and hydration status in humans. However, the investigators do not know its regulatory relationship with measurements of fluid balance when supplemented through the skin.
