Comparative Study Clinical TrialPro- and anti-inflammatory cytokines in chronic pediatric dialysis patients: effect of aspirin.
Dialysis provides effective and safe treatment of ESRD in children, but patients who are maintained on chronic dialysis are at risk for cardiovascular disease. One major risk factor for cardiovascular disease in adult patients with ESRD is chronic inflammation. The effect of anti-inflammatory therapy with aspirin on serum cytokine concentration was studied in seven children who were receiving hemodialysis (HD) and seven who were receiving continuous cycling peritoneal dialysis (CCPD or PD). ⋯ The effect of aspirin treatment on serum cytokine concentrations was similar for HD and PD patients. In HD patients, IL-6, IL-8, and TNF-alpha remained suppressed 1 mo after discontinuation of aspirin. It is concluded that proinflammatory cytokines are elevated in pediatric HD and PD patients without counterbalance from anti-inflammatory cytokines, and aspirin therapy attenuates inflammation.

Facilitating advance care planning for patients with end-stage renal disease: the patient perspective.
Comprehensive care of patients with ESRD requires expertise in advance care planning (ACP), including attention to ethical, psychosocial, and spiritual issues related to starting, continuing, withholding, and stopping dialysis. However, there are no standards of care regarding when to initiate or how to facilitate ACP. The purpose of this study was to determine the perspectives of patients with ESRD of the salient elements of ACP discussions. ⋯ The role of patients and family within ACP is complex and varies significantly between patients. For most, family was an integral component of ACP, and many relied extensively on family to make end-of-life decisions. These findings identify a precarious tension between patients' preferences in terms of facilitated ACP and current clinical practice.

Randomized Controlled TrialN-3 fatty acids as secondary prevention against cardiovascular events in patients who undergo chronic hemodialysis: a randomized, placebo-controlled intervention trial.
Patients who are treated with chronic hemodialysis (HD) experience premature cardiovascular disease and an increased mortality. N-3 polyunsaturated fatty acids (PUFA) may be effective in the secondary prevention of cardiovascular disease, but the effects of n-3 PUFA has not previously been examined in HD patients. It was hypothesized that secondary prevention with n-3 PUFA would reduce the number of cardiovascular events and death in patients who are treated with chronic HD. ⋯ This trial was limited by a relatively small number of patients and a large number of withdrawals. However, it is concluded that treatment with n-3 PUFA did not reduce the total number of cardiovascular events and death in this high-risk population. N-3 PUFA significantly reduced the number of myocardial infarctions as a secondary outcome, a finding that might be of clinical interest.

Handcarried ultrasound measurement of the inferior vena cava for assessment of intravascular volume status in the outpatient hemodialysis clinic.
Accurate intravascular volume assessment is critical in the treatment of patients who receive chronic hemodialysis (HD) therapy. Clinically assessed dry weight is a poor surrogate of intravascular volume; however, ultrasound assessment of the inferior vena cava (IVC) is an effective tool for volume management. This study sought to determine the feasibility of using operators with limited ultrasound experience to assess IVC dimensions using hand-carried ultrasounds (HCU) in the outpatient clinical setting. ⋯ HCU measurement of the IVC is a feasible option for rapid assessment of intravascular volume status in an outpatient dialysis setting by operators with limited formal training in echocardiography. There is a poor relationship between dry weight goals and IVC collapsibility. Practice variation in the maintenance of volume status is correlated with significant differences in intradialysis adverse events.
