Randomized Controlled Trial Multicenter StudySelective aldosterone blockade with eplerenone reduces albuminuria in patients with type 2 diabetes.
Previous studies have shown that the selective aldosterone blocker eplerenone, in doses of up to 200 mg/d, reduces albuminuria in patients with type 2 diabetes. This study was conducted to ascertain whether lower doses of eplerenone (50 or 100 mg/d) co-administered with the angiotensin-converting enzyme (ACE) inhibitor enalapril would produce a similar antialbuminuric effect while obviating the hyperkalemia observed previously. After open-label run-in with enalapril 20 mg/d, patients with diabetes and a urinary albumin:creatinine ratio (UACR) > or = 50 mg/g were randomly assigned to receive enalapril plus one of three double-blind daily treatments for 12 wk: placebo, eplerenone 50 mg (EPL50), or eplerenone 100 mg (EPL100). ⋯ For the secondary end points, both eplerenone treatment groups significantly reduced albuminuria from baseline as early as week 4 (P < 0.001), whereas placebo treatment (including enalapril) did not result in any significant decreases in UACR. Systolic BP decreased significantly in all treatment groups at all time points, but, generally, all treatment groups experienced similar decreases in BP. Co-administration of EPL50 or EPL100 with an ACE inhibitor as compared with an ACE inhibitor alone significantly reduces albuminuria in patients with diabetes without producing significant increases in hyperkalemia.

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.
