Anti-platelete in HD

Reduction in renal clearance and removal by hemodialysis adversely affect the level and utility of high-sensitivity troponin I (hsTnI) for diagnosis of acute myocardial infarction (AMI) in hemodialysis (HD) patients. Furthermore, HD process itself might cause undesirable myocardial injury and enhance post HD hsTnI levels. This comparative cross-sectional study was conducted to compare the hsTnI levels between 100 asymptomatic HD patients and their 107 matched non-chronic kidney disease (CKD) population. The hsTnI levels in HD group were higher than non-CKD group [median (IQR): 54...

OBJECTIVES: Catheter-related right atrial thrombosis (CRAT) is an underreported but potentially life-threatening complication associated with the use of tunneled-cuffed catheters among hemodialysis (HD) patients. Because little is known about the evidence-based guidelines for the optimal management of CRAT among HD patients, this article reports findings based on 20 patients diagnosed with CRAT after catheter replacement and anticoagulation treatment. METHODS: The article retrospectively reviews the hospital records of 20 HD patients treated in the West China Hospital with diagnosis of CRAT from March 2013 to May 2016...

BACKGROUND: Restenosis remains a problem in hemodialysis access interventions. Paclitaxel-coated balloons have shown promise in reducing access-related restenosis in small trials. The primary hypotheses for our multicenter trial were superior effectiveness at 180 days and noninferior safety at 30 days of a drug-coated balloon compared with conventional angioplasty for treatment of dysfunctional arteriovenous fistulas. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This randomized trial enrolled 285 patients with dysfunctional arteriovenous fistulas at 23 centers...

INTRODUCTION: Fibrinolysis is one of the methods extending the use of vascular access in patients with tunneled venous catheters thrombosis. The aim of this study was to assess one-year maintenance of tunneled catheters patency after first effective thrombolysis with urokinase and identify its predictors. METHODS: Retrospective analysis included 85 patients (age 69 ± 13 years) with permanent venous catheter thrombosis treated with urokinase at one center in the period 2010-2016...

Appropriate anticoagulation for hemodialysis (HD) requires a subtle balance between under- and over-heparinization to prevent extracorporeal circuit (ECC) clotting and bleeding, respectively. We discuss five key issues relating to anticoagulation therapy for chronic HD in adults following a review of relevant literature published since 2002: (i) options for standardization of anticoagulation in HD settings. The major nephrology societies have issued low evidence level recommendations on this subject. Interventional studies have generally investigated novel low-molecular weight heparins and provided data on safety of dosing regimens that cannot readily be extrapolated to clinical practice; (ii) identification of clinical and biological parameters to aid individualization of anticoagulation treatment...

BACKGROUND: Antiplatelet agents are used to prevent cardiovascular events; however, treatment effects may differ in persons with chronic kidney disease (CKD) because atherosclerotic disease is less prevalent, whereas bleeding hazards may be increased in this population. PURPOSE: To summarize the effects of antiplatelet treatment on cardiovascular events, mortality, and bleeding in persons with CKD. DATA SOURCES: Embase and Cochrane databases through November 2011 without language restriction...
