BACKGROUND: Patients with end-stage renal disease (ESRD) are at a high risk of cardiovascular mortality (CVM). In patients with ESRD, arterial stiffness increases at an earlier age when compared to the general population and this contributes to the overall risk of cardiovascular mortality. The main objective of this study was to clarify the interplay between age and cardiovascular alterations in ESRD. METHODS: Prospective, observational cohort study initiated in April 1987 until the end of 1998 with events recorded until the end of the year 2000 at the F...

BACKGROUND: Information on an individual's risk for death following dialysis therapy initiation may inform the decision to initiate maintenance dialysis for older adults. We derived and validated a clinical risk prediction tool for all-cause mortality among older adults during the first 6 months of maintenance dialysis treatment. STUDY DESIGN: Prediction model using retrospective administrative and clinical data. SETTING & PARTICIPANTS: We linked administrative and clinical data to define a cohort of 2,199 older adults (age ≥ 65 years) in Alberta, Canada, who initiated maintenance dialysis therapy (excluding acute kidney injury) in May 2003 to March 2012...

REVIEW
Manish Saha, Michael Allon
Given the high comorbidity in patients on hemodialysis and the complexity of the dialysis treatment, it is remarkable how rarely a life-threatening complication occurs during dialysis. The low rate of dialysis emergencies can be attributed to numerous safety features in modern dialysis machines; meticulous treatment and testing of the dialysate solution to prevent exposure to trace elements, toxins, and pathogens; adherence to detailed treatment protocols; and extensive training of dialysis staff to handle medical emergencies...

Maintenance dialysis patients experience a high burden of physical and emotional symptoms that directly affect their quality of life and health care utilization. In this review, we specifically highlight common troublesome symptoms affecting dialysis patients: insomnia, restless legs syndrome, and uremic pruritus. Epidemiology, pathophysiology, and evidence-based current treatment are reviewed with the goal of providing a guide for diagnosis and treatment. Finally, we identify multiple additional areas of further study needed to improve symptom management in dialysis patients...

REVIEW
Panagiotis I Georgianos, Rajiv Agarwal
The diagnosis and management of hypertension among patients on chronic dialysis is challenging. Routine peridialytic blood pressure recordings are unable to accurately diagnose hypertension and stratify cardiovascular risk. By contrast, blood pressure recordings taken outside the dialysis setting exhibit clear prognostic associations with survival and might facilitate the diagnosis and long-term management of hypertension. Once accurately diagnosed, management of hypertension in individuals on chronic dialysis should initially involve non-pharmacological strategies to control volume overload...

PURPOSE OF REVIEW: This review focuses on recent advances in our understanding of intradialytic hypotension (IDH) and measures that may reduce its frequency. RECENT FINDINGS: The frequency and severity of IDH predict the risk for adverse clinical outcomes. The highest mortality risks associated with IDH were observed when the intradialytic systolic blood pressure (SBP) nadirs were <90 and <100 mmHg and the predialysis SBP were ≤159 mmHg or ≥160 mmHg, respectively...

BACKGROUND: Hyperkalemia is common in patients receiving maintenance hemodialysis. However, few studies have examined the association between serum potassium level and mortality. METHODS: This study used annual cohorts of hemodialysis patients during 2007-2010. To determine hyperkalemia prevalence, monthly hyperkalemia was defined as serum potassium level ≥5.5 mEq/l; prevalence was calculated as a ratio of hyperkalemia episodes to follow-up time, reported separately by long and short interdialytic interval...

INTRODUCTION: Intradialytic hypertension with a prevalence of 15% among hemodialysis patients is with unknown pathophysiology, demographic, laboratoiy and clinical characteristic of patients, and it's influence on longtenn clinical effects (cardiovascular morbidity and mortality, rate of hospitalization). The aim of the study is to present the clinical, laboratoiy and demographic characteristics of patients with intradialytic hypertension in our dialysis center. MATERIALS AND METHODS: Out of 110 hemodialysis patients, 17 patients (15,45%) had intradialytic hypertension - started at a systolic pressure greater than 140 nun Hg or had an increase in systolic pressure more than 10 mm Hg during the session, and 17 patients were nonnotensive or had a drop in blood pressure dining the dialysis...

Chronic fatigue--an overwhelming subjective feeling of mental or physical exhaustion--impacts patients' everyday functioning and quality of life, delays recovery after hemodialysis, and increases mortality. There are a number of factors that may perpetuate clinically significant fatigue among individuals with chronic kidney disease, including sleep disorders, depression, sedentary lifestyle, anemia, and chronic inflammation. Some of these factors (i.e., anemia and inflammation) are in the forefront of clinical attention, whereas the other contributing factors often remain unrecognized...

BACKGROUND AND OBJECTIVES: The International Society of Renal Nutrition and Metabolism (ISRNM) has recently recommended the use of the term "protein-energy wasting" (PEW). PEW is a state of malnutrition with decreased body stores of protein and energy fuel in hemodialysis patients and is known as a risk factor for morbidity and mortality. We examined the prevalence of PEW and the characteristics of PEW patients in a hemodialysis center in Japan. METHODS AND STUDY DESIGN: Fifty-nine outpatients undergoing maintenance hemodialysis at Iga City General Hospital were evaluated...

The recent epidemiologic data pointed out, that the general number of patients on hemodialysis is steadily increasing, especially in group of elderly patients over 75 years old. The geriatric syndromes are a multietiological disorder related to physiological aging and partly associated with comorbid conditions. Frailty, falls, functional decline and disability, cognitive impairment and depression are main geriatric syndromes and occurs in patients with impaired renal function more often than among general population...

BACKGROUND: For patients with end-stage renal disease who are not candidates for fistula, dialysis access grafts are the best option for chronic haemodialysis. However, polytetrafluoroethylene arteriovenous grafts are prone to thrombosis, infection, and intimal hyperplasia at the venous anastomosis. We developed and tested a bioengineered human acellular vessel as a potential solution to these limitations in dialysis access. METHODS: We did two single-arm phase 2 trials at six centres in the USA and Poland...

REVIEW

The heart and the vascular tree undergo major structural and functional changes when kidney function declines and renal replacement therapy is required. The many cardiovascular risk factors and adaptive changes the heart undergoes include left ventricular hypertrophy and dilatation with concomitant systolic and diastolic dysfunction. Myocardial fibrosis is the consequence of impaired angio-adaptation, reduced capillary angiogenesis, myocyte-capillary mismatch, and myocardial micro-arteriopathy. The vascular tree can be affected by both atherosclerosis and arteriosclerosis with both lipid rich plaques and abundant media calcification...

PURPOSE: Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were established showing the poor prognosis in some diseases, such as cardiovascular diseases and malignancies. The risk of mortality in patients with end-stage renal disease (ESRD) was higher than normal population. In this study, we aimed to investigate the relationship between NLR, PLR, and all-cause mortality in prevalent hemodialysis (HD) patients. METHODS: Eighty patients were enrolled in study...

The evidence that chronic hepatitis C plays a detrimental role in survival among patients on maintenance dialysis or renal transplant recipients promotes the antiviral treatment of hepatitis C virus (HCV) among chronic kidney disease patients. Also, it seems that HCV infection is associated with an increased risk of developing chronic kidney disease in the adult general population. Interferon-based regimens have provided limited efficacy and safety among chronic kidney disease patients, whereas the advent of the new direct-acting antivirals for the treatment of hepatitis C (launched over the past 5 years) has given the opportunity to reach sustained virologic response rates of 90% for many patient groups...

REVIEW
Stephanie M Toth-Manikowski, Stephen M Sozio
The use of cooled dialysate temperatures first came about in the early 1980s as a way to curb the incidence of intradialytic hypotension (IDH). IDH was then, and it remains today, the most common complication affecting chronic hemodialysis patients. It decreases quality of life on dialysis and is an independent risk factor for mortality. Cooling dialysate was first employed as a technique to incite peripheral vasoconstriction on dialysis and in turn reduce the incidence of intradialytic hypotension. Although it has become a common practice amongst in-center hemodialysis units, cooled dialysate results in up to 70% of patients feeling cold while on dialysis and some even experience shivering...

Heart failure (HF) is the most frequent cardiovascular disease associated with chronic kidney disease and represents a high risk for cardiovascular mortality in incident hemodialysis (HD) patients. This risk is especially high during the arteriovenous fistula (AVF) maturation period due to the marked hemodynamic changes related to the large increase in the blood flow and also within the first 120 days after HD inception because in this period the highest mortality rate occurs. When planning the vascular access for each incident HF patient, the risk of aggravating HF after AVF creation must be evaluated carefully alongside the risk of catheter-related complications, but avoiding a non-selective 'catheter first' approach for all these patients...

Initiation of thrice-weekly hemodialysis often results in a rapid loss of residual kidney function (RKF) including reduction in urine output. Preserving RKF longer is associated with better outcomes including greater survival in dialysis patients. An alternative approach aimed at preserving RKF is an incremental transition with less frequent hemodialysis sessions at the beginning with gradual increase in hemodialysis frequency over months. In addition to favorable clinical and economic implications, an incremental transition would also enhance a less stressful adaptation of the patient to dialysis therapy...

BACKGROUND AND OBJECTIVES: Intradialytic hypoxemia has been recognized for decades, but its associations with outcomes have not yet been assessed in a large patient cohort. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Our retrospective cohort study was conducted between January of 2012 and January of 2015. We recorded blood oxygen saturation every minute during hemodialysis in patients with arteriovenous access. A 6-month baseline period with at least 10 treatments with oxygen saturation measurements preceded a 12-month follow-up...
