BACKGROUND: Serum calcium concentration (Ca) plays an essential role in a vascular muscle tone and myocardial contractility. Previously, we showed that acutely lowering Ca by hemodialysis reduced arterial stiffness. Cinacalcet is a calcimimetic that lowers Ca and parathyroid hormone (PTH). The aim of the present study was to examine whether acute lowering of Ca by cinacalcet improves vascular stiffness and myocardial diastolic dysfunction. METHOD: This is a double-blinded randomized placebo-controlled crossover study that included 21 adult patients with end-stage kidney disease undergoing chronic hemodialysis...

PURPOSE: We investigated the possible association between coping style and depressive feelings among caregivers of end-stage renal disease patients undergoing hemodialysis. METHODS: We studied 107 main caregivers of hemodialysis patients. Main caregiver was defined as the person on whom the patient counts for daily care or the one the patient calls upon in case of difficulties. Demographic data of caregivers and clinical data of patients were collected. The Jalowiec Coping Scale was applied to score two styles of coping: problem-oriented coping (POC) and emotion-oriented coping (EOC)...

Hyperkalemia is not uncommon in patients with end-stage renal disease (ESRD) on maintenance hemodialysis, often related to dietary indiscretion, following the prolonged inter-dialytic weekend interval in patients on thrice weekly hemodialysis treatments, and sometimes the adverse effects of medications such as RAAS blocking agents. Moreover, hyperkalemia following extended cardiac surgery can result from the use of high-potassium containing cardioplegic solutions used during cardiopulmonary bypass. Nevertheless, different from the foregoing, in the nephrology literature, there have been very rare reports of potentially life-threatening hyperkalemia following cardiac valve replacement procedure...

BACKGROUND: The association between preoperative aspirin use and postoperative acute kidney injury (AKI) in cardiovascular surgery is unclear. We sought to evaluate the effect of preoperative aspirin use on postoperative AKI in cardiac surgery. METHODS: A total of 770 patients who underwent cardiovascular surgery under cardiopulmonary bypass were reviewed. Perioperative clinical parameters including preoperative aspirin administration were retrieved. We matched 108 patients who took preoperative aspirin continuously with patients who stopped aspirin more than 7 days or did not take aspirin for the month before surgery...

Hypertension (HT) is present in more than 80% of patients undergoing hemodialysis (HD). Elevated blood pressure (BP) in hemodialysis patients is associated with cardiovascular events and mortality only when BP is recorded with home or ambulatory monitoring, since pre- and post-dialysis measurements are not valid estimates of BP levels during the inter-dialytic interval. Sodium and water overload is the most important of several mechanisms involved in HT development in HD. In this context, non-pharmacologic measures to ensure water and sodium balance by achieving patient dry weight and decreasing daily sodium intake, through modification of sodium level in the diet or in dialysis dialysate, are fundamental for HT control...

INTRODUCTION: Volume overload and the renin-aldosterone-angiotensin system (RAAS) are 2 major factors contributing to hypertension (HTN) among hemodialysis (HD) patients. Although volume-dependent components of HTN can be corrected by appropriate volume removal, a proportion of HD patients experience elevated blood pressure (BP) despite achieving euvolemic and ideal dry weight. METHOD AND ANALYSIS: A single center, prospective, randomized, parallel design, single-blind trial will be conducted in the Malaysian state of Kelantan among postdialysis euvolemic hypertensive patients that are on regular dialysis at least 3 times a week...

BACKGROUND: Patients with end-stage renal disease (ESRD) on maintenance hemodialysis (HD) respond poorly to clopidogrel. We assessed the utility of low-dose ticagrelor in ESRD patients on maintenance HD. METHODS: In this single-center, prospective, randomized pharmacodynamic study, 52 ESRD patients on HD were prescribed clopidogrel (300mg loading dose [LD], then 75mg daily), standard-dose ticagrelor (180mg LD, then 90mg twice daily), or low-dose ticagrelor (90mg LD, then 90mg daily) for 14days...

It is unclear whether warfarin is protective or harmful in patients with ESRD and atrial fibrillation. This state of equipoise raises the question of whether alternative anticoagulants may have a therapeutic role. We aimed to determine apixaban pharmacokinetics at steady state in patients on hemodialysis. Seven patients received apixaban 2.5 mg twice daily for 8 days. Blood samples were collected before and after apixaban administration on days 1 and 8 (nondialysis days). Significant accumulation of the drug was observed between days 1 and 8 with the 2...

INTRODUCTION: End-stage renal disease (ESRD) is associated with perturbations in thyroid hormone concentrations and an increased prevalence of hypothyroidism. Few studies have examined the effects of hemodialysis dose or frequency on endogenous thyroid function. METHODS: Within the Frequent Hemodialysis Network (FHN) trials, we examined the prevalence of hypothyroidism in patients with ESRD. Among those with endogenous thyroid function (without overt hyper/hypothyroidism or thyroid hormone supplementation), we examined the association of thyroid hormone concentration with multiple parameters of self-reported health status, and physical and cognitive performance, and the effects of hemodialysis frequency on serum thyroid stimulating hormone (TSH), free thyroxine (FT4), and free tri-iodothyronine (FT3) levels...

REVIEW
Dana C Miskulin, Daniel E Weiner
Despite having thousands of blood pressure (BP) readings on individual dialysis patients over the course of a year, our knowledge about the optimal assessment of BP, the mechanisms underlying hypertension and its management remain incomplete. Observational studies reveal that BP is lower at home than when measured in the dialysis unit. However, we do not know if using home vs. in-center measurements to guide treatment decisions improves BP control and/or clinical outcomes. Moreover, a recent US study suggests that typical hemodialysis patients are unlikely to adhere to home monitoring over the long term...

Simvastatin induced rhabdomyolysis with renal failure is a well reported clinical entity with hyperkalemia recognized as a life threatening risk. The risk of delayed hypercalcemia during the recovery of renal function is not well appreciated as this varies in severity and can be caused by multiple mechanisms. We present a patient with high dose simvastatin induced rhabdomyolysis leading to late onset of severe hypercalcemia due to calcium phosphate deposition in muscles diagnosed by distinctive bone scintigraphy...

Hyperphosphatemia is common among patients with CKD stage 5D and is associated with morbidity and mortality. Current guidelines recommend lowering serum phosphate concentrations toward normal. Tenapanor is a minimally absorbed small molecule inhibitor of the sodium/hydrogen exchanger isoform 3 that functions in the gut to reduce sodium and phosphate absorption. This randomized, double-blind, placebo-controlled trial assessed the effects of tenapanor on serum phosphate concentration in patients with hyperphosphatemia receiving hemodialysis...
