Cardiovascular and Stroke Risk in Japanese Hemodialysis Patients With Atrial Fibrillation
Abstract Atrial fibrillation is one of the most common arrhythmias in hemodialysis patients. We evaluated its clinical outcomes among hemodialysis patients with atrial fibrillation in Japan. Using data derived from the Japanese Dialysis Outcomes and Practice Patterns Study, we analyzed backgrounds and outcomes among hemodialysis patients with and without atrial fibrillation in Japan. Among 7002 hemodialysis patients, the prevalence of atrial fibrillation was 5.7% and the incidence was 0.2 per 100 patient‐years. Atrial fibrillation was independently associated with all‐cause mortality (hazard ratio, 1.32; 95% confidence...

Dabigatran treatment simulation in patients undergoing maintenance haemodialysis.
This study simulated the dose-exposure relationship of dabigatran in patients undergoing haemodialysis. Dabigatran exposure was modelled at once- and twice-daily doses of 75 mg, 110 mg and 150 mg and at variations in non-renal clearance and dialysis settings. Resultant dose exposure (area under the curve [AUC]) was compared with values simulated from typical patients in the RE-LY® trial (based on a previously characterised pharmacometric model). In this simulation, all twice-daily dosages resulted in exposures above those simulated from typical RE-LY patients (1.5- to 3.3-fold increase in AUC) and thus may not be optimal ...

Prevalence and correlates of functional dependence among maintenance dialysis patients
Abstract Functional dependence is an important determinant of longevity and quality of life. The purpose of the current study was to determine the prevalence and correlates of functional dependence among patients with end‐stage renal disease (ESRD) receiving maintenance dialysis. We enrolled 148 participants with ESRD from five clinics. Functional status, as measured by basic and instrumental activities of daily living (ADL, IADL), was ascertained by validated questionnaires. Functional dependence was defined as needing assistance in at least one of seven IADLs or at least one of four ADLs. Demographic characteristics, c...

Pharmacokinetics, safety, and tolerability of edoxaban in end-stage renal disease subjects undergoing haemodialysis.
In conclusion, based on these single-dose PK data, a supplementary dose of edoxaban may not be required following a haemodialysis session. Importantly, haemodialysis is not an effective mechanism for removal of edoxaban from the blood. PMID: 25566930 [PubMed - as supplied by publisher]

Clopidogrel Use in End‐Stage Kidney Disease
In conclusion, current evidence suggests that ESKD patients may not derive the same benefits from clopidogrel therapy as the general population and this therapy may be associated with harm. Properly designed observational studies and randomized controlled trials are needed to establish the role of clopidogrel in patients with ESKD, the use of platelet assays to tailor therapy, and the role of other antiplatelet agents such as prasugrel or ticagrelor in patients who exhibit high on‐treatment residual platelet reactivity.

Changes in Volumetric Hemodynamic Parameters Induced by Fluid Removal on Hemodialysis in Critically Ill Patients
Abstract Management of volume status is difficult in critically ill patients with renal failure. Volumetric hemodynamic indices are increasingly being used to guide fluid therapy in the intensive care unit (ICU), but are not established to monitor hemodialysis‐induced fluid removal in critically ill patients. Using volumetric hemodynamic monitoring, changes in extravascular lung water index (EVLWI) and intrathoracic blood volume index (ITBVI) were measured immediately before and after hemodialysis sessions in 35 ICU patients. Additional hemodynamic and oxygenation related parameters were recorded at the same time, and on...

Higher Mortality Due to Intracerebral Hemorrhage in Dialysis Patients: A Comparison with the General Population in Japan
Abstract Cerebrovascular diseases, including intracerebral hemorrhage, cerebral infarction, and subarachnoid hemorrhage, remain prevalent causes of morbidity and mortality among dialysis patients. Their mortality rate for cerebrovascular diseases is roughly three times higher than that in the general population. However, whether mortality rates for all subtypes of cerebrovascular diseases are equally higher has not been evaluated. The aim of this study was to determine the mortality rate for each stroke subtype, comparing dialysis patients and the general population in Japan. We used mortality data reported by the Japanese...

Erythropoiesis-stimulating agents and thrombotic events in dialysis patients
Erythropoiesis-stimulating agents (ESA) have been associated with a higher cardiovascular event and mortality rate in dialysis patients. The ESA-associated risk of arterial thrombotic events is mainly based on composite endpoints of anemia-correction trials targeting high hemoglobin levels. The ESA-associated risk of venous thromboembolism (VTE) has not been studied in dialysis patients yet. We therefore aimed to determine the association between ESA use and dose with ischemic stroke, myocardial infarction (MI) and VTE.

Piperacillin/tazobactam‐induced neurotoxicity in a hemodialysis patient: A case report
This report presents a case of a hypertensive and diabetic 67‐year‐old woman in regular hemodialysis, which previously had a stroke. She was hospitalized presenting pneumonia, which was initially treated with cefepime. Two days after treatment, she presented dysarthria, left hemiparesis, ataxia, and IX and X cranial nerves paresis. Computed tomography showed no acute lesions and cefepime neurotoxicity was hypothesized, and the antibiotic was replaced by piperacillin/tazobactam. The neurologic signs disappeared; however, 4 days after with piperacillin/tazobactam treatment, the neurological manifestations returned. A new...

Evidence for the Prevention and Treatment of Stroke in Dialysis Patients
Abstract The risks of both ischemic and hemorrhagic stroke are particularly high in dialysis patients of any age and outcomes are poor. It is therefore important to identify strategies that safely minimize stroke risk in this population. Observational studies have been unable to clarify the relative importance of traditional stroke risk factors such as blood pressure and cholesterol in those on dialysis, and are affected by biases that usually make them an inappropriate source of data on which to base therapeutic decisions. Well‐conducted randomized trials are not susceptible to such biases and can reliably investigate t...

Practical Approach to Evaluate Asymptomatic Coronary Artery Disease in End‐Stage Renal Disease Patients at the Initiation of Dialysis
Abstract The high prevalence of significant asymptomatic coronary artery disease (CAD) has been reported in patients with end‐stage renal disease (ESRD) at the initiation of dialysis. However, the approach to evaluate asymptomatic CAD for these patients has not been established. The aim of this study is to assess the applicability of our practical approach at the initiation of dialysis. We prospectively enrolled 182 consecutive ESRD patients who initiated dialysis. After echocardiography as primary screening, pharmacologic stress thallium‐201 scintigraphy and/or coronary angiography (CAG) were performed to diagnose CAD...
