BACKGROUND: The evaluation and management of fluid balance are key challenges in critical care patients who require renal replacement therapies because cumulative fluid balance is an independent factor that increases morbidity and mortality in different clinical scenarios. SUMMARY: One of the strategies when fluid overload is refractory to diuretics, is extracorporeal fluid removal (i.e., net ultrafiltration [UFNET] during kidney replacement therapy). However, problems with UFNET without individualized assessment are cardiovascular events and intradialytic hypotension, events that contribute to decreasing organ perfusion and sympathetic stress...

INTRODUCTION: Lowering dialysate sodium may improve volume and blood pressure control in maintenance hemodialysis patients. METHODS: We randomized 42 participants 2:1 to dialysate sodium 135 vs. 138 mEq/L for 6 months. This was followed by a 12 week extension in which sodium was increased to 140 mEq/L in low arm participants. The primary outcome was intradialytic hypotension (IDH). Secondary outcomes included dialysis disequilibrium symptoms, ER visits/hospitalizations, interdialytic weight gain, blood pressure (BP)...

PURPOSE: Low physical function can be effectively improved via intradialytic exercise. However, the association between the effects of intradialytic exercise on physical function and malnutrition severity has not been studied extensively. This study aimed to investigate the impact of nutritional status severity on physical function in patients undergoing hemodialysis with low physical function to whom intradialytic exercise was prescribed. METHODS: The participants were patients with decreased mobility [walking speed < 1...

BACKGROUND: Sarcopenia is common in hemodialysis patients. This study aimed to evaluate the effect of simultaneous nutritional support and intradialytic neuromuscular electrical stimulation (NMES) in hemodialysis patients. METHODS: We performed a 12-week, multicenter, randomized controlled trial. The participants were randomly assigned to the control group, the protein group (25 g of protein at every dialysis session), the NMES group (intradialytic NMES to quadriceps femoris muscles), and the NMES + P group (NMES with protein supplementation)...

Maintaining independence is the top health-related priority reported by older patients with advanced kidney disease.1 Unfortunately, functional losses such as fatigue, skeletal muscle loss, infection, cognitive decline, and diminished aerobic capacity are very common among patients receiving hemodialysis for chronic kidney failure. Such functional losses are associated with higher mortality2-4 and affect patients' physical activity level and overall quality of life. Indeed, symptom burden and mortality in patients receiving hemodialysis rival those in patients with cancer...

RATIONALE & OBJECTIVE: Intradialytic hypotension (IDH) is associated with mortality in adults with kidney failure requiring hemodialysis (HD); however, large-scale pediatric studies are lacking. Moreover, there is no evidence-based consensus definition of IDH in pediatric literature. We aimed to examine the association of commonly used definitions of IDH with mortality in adolescents and young adults. STUDY DESIGN: This was a retrospective observational cohort study...

INTRODUCTION: Continuous monitoring of relative blood volume (percentage BV) in hemodialysis (HD) is critical for determining dry weight and preventing intradialytic hypotension. However, the cause of the blood volume variation remains unknown. This research aims to examine factors that influence the percentage BV. METHODS: We devised a formula based on coefficients ("a," "τ" and "b") to predict changes in percentage BV. "a" denotes a significant decrease in percentage BV in the early stages of HD...

BACKGROUND: Cardiovascular disease is the leading cause of death among people with kidney failure on hemodialysis, for whom improving cardiovascular health is a research priority. Intradialytic myocardial stunning is common and associated with adverse cardiovascular events. Intradialytic exercise may mitigate intradialytic myocardial stunning and improve cardiovascular structure and function. This systematic review investigated the effect of intradialytic exercise on cardiovascular outcomes in adults undergoing maintenance hemodialysis (PROSPERO #CRD42018103118)...

Occasionally, patients undergoing dialysis develop acute severe hypotension that requires interruption of dialysis within minutes of initiating every dialysis session. Although the underlying causes of recurrent intradialytic hypotension are evaluated extensively, including dialysis-associated allergic reactions or other possible causes, the definitive cause is sometimes missed. Dialysis is a life-sustaining procedure; therefore, prompt identification and management of the underlying cause of dialysis intolerance are crucial...

Hemodialysis (HD) is a life-saving treatment for patients with kidney failure. However, patients requiring HD have a 10-20 times higher risk of cardiovascular (CV) morbidity and mortality than that of the general population. Patients encounter complications such as episodic intradialytic hypotension (IDH), abnormal perfusion to critical organs (heart, brain, liver, and kidney) and damage to vulnerable vascular beds. Recurrent conventional HD exposes patients to multiple episodes of circulatory stress, exacerbating and being aggravated by microvascular endothelial dysfunction...

A method of overcoming barriers associated with implementing lifestyle interventions in CKD may be through the use of eHealth technologies. The aim of this review was to provide an up-to-date overview of the literature on this topic. Four bibliographical databases, two trial registers, and one database for conference proceedings were searched from inception to August 2023. Studies were eligible if they reported a lifestyle intervention using eHealth technologies. A narrative synthesis of the findings from the included studies structured around the type of eHealth intervention was presented...

Hemodialysis (HD) patients suffer from multiple health problems, including severe insulin resistance. Both cold dialysis and intradialytic exercise training could elicit health benefits; however, it is still unknown whether the combination of those two approaches could enhance overall health. The current study aimed to evaluate the separate and combined acute effects of a single session of cold dialysis and intradialytic exercise in parameters related to insulin sensitivity and glucose disposal. Ten HD patients (57...

There are several forms of maintenance high-efficiency hemodialysis (HD), including hemodiafiltrations (HDF) in different technical modes and expanded HD, using dialyzers with medium cut-off membranes. The aim of the study was to assess the intradialytic tolerance and length of dialysis recovery time (DRT) in these modalities. This is an exploratory, crossover study in maintenance HD patients with low comorbidity and no clinical indications for the use of high-efficiency HD, who were exposed to five intermittent dialyses in random order: high-flux hemodialysis (S-HD), expanded HD (HDx), pre-dilution HDF (PRE-HDF), mix-dilution HDF (MIX-HDF) and post-dilution HDF (POST-HDF)...

PURPOSE: Exercise therapy is a crucial intervention for improving health-related quality of life (HRQOL) in patients undergoing haemodialysis. However, factors that improve HRQOL by improving physical function and dialysis-related symptoms remain unknown. This study aimed to examine the physical function parameters and dialysis-related symptoms that improve HRQOL following intradialytic exercise. METHODS: This multicentre cohort study included 596 patients who participated in an intradialytic exercise program three times per week for a period of 6 months, which comprised of stretching and resistance training...

INTRODUCTION: Accumulation of β2-microglobulin (B2M) in dialysis patients contributes to several comorbidities of end stage kidney disease (ESKD). The LIXELLE® device adsorbs B2M from blood using sorbent bead technology. Studies in Japan showed LIXELLE treatment during hemodialysis (HD) at blood flow rates up to 250 mL/min removes B2M above HD alone and is well-tolerated. We investigated tolerance for LIXELLE treatment during HD at higher HD blood flow rates standard in the United States (US)...

In patients undergoing hemodialysis, the impact of atrial fibrillation (AF) through cardiac thromboembolism on the development of ischemic stroke may be influenced by the severity of atherosclerosis present. However, there are no large-scale reports confirming whether the severity of atherosclerosis influences the relationship between AF and stroke development in patients requiring hemodialysis. We aimed to investigate the effects of atherosclerotic disease on the relationship between AF and new-onset ischemic stroke...

BACKGROUND: Intradialytic hypotension (IDH) is a common hemodialysis complication causing adverse outcomes. Despite the well-documented associations of ambient temperatures with fluid removal and pre-dialysis blood pressure (BP), the relationship between ambient temperature and IDH has not been adequately studied. METHODS: We conducted a cohort study at a tertiary hospital in southern Taiwan between 1 January 2016 and 31 October 2021. The 24-h pre-hemodialysis mean ambient temperature was determined using hourly readings from the weather station closest to each patient's residence...

Intradialytic hypotension (IDH) is a common complication of hemodialysis (HD), but there is no consensus on its definition. In 2015, Flythe proposed a definition of IDH (Definition 1 in this study): nadir systolic blood pressure (SBP) <90 mmHg during hemodialysis for patients with pre-dialysis SBP <159 mmHg, and nadir SBP <100 mmHg during hemodialysis for patients with pre-dialysis SBP ≥160 mmHg. This prospective observational cohort study investigated the association of frequent IDH based on Definition 1 with clinical outcomes and compared Definition 1 with a commonly used definition (nadir SBP <90 mmHg during hemodialysis, Definition 2)...
