- Objective. There have been no endpoint studies with statins for patients with severe renal failure. The purpose of this prospective, open, randomized, controlled study was to investigate whether atorvastatin (10 mg/day) would alter cardiovascular endpoints and the overall mortality rate of patients with chronic kidney disease stage 4 or 5 (creatinine clearance < 30 ml/min).Material and methods. The study subjects comprised 143 patients who were randomized either to placebo (controls; n=73; mean age 69.5 years) or to treatment with atorvastatin (n=70; mean age 67.9 years). The patients included were either non-dialysis (n=33), haemodialysis (n=97) or peritoneal dialysis (n=13) patients. Analysis focused on the primary endpoints of all-cause mortality, non-lethal acute myocardial infarction, coronary artery bypass graft surgery and percutaneous transluminal coronary angioplasty. Statistical analysis for endpoint data was mainly by intention-to-treat.Results. Primary endpoints occurred in 74% of the subjects. There was no difference in outcome between the control and atorvastatin groups. The 5-year endpoint-free survival rate from study entry was 20%. Atorvastatin was withdrawn in 20% of patients due to unacceptable side-effects. In the atorvastatin group, low-density lipoprotein (LDL) cholesterol was reduced by 35% at 1 month and then sustained. The controls showed a progressive reduction in LDL cholesterol until 36 months.Conclusions. Although atorvastatin reduced total and LDL cholesterol effectively it was not beneficial regarding the long-term outcomes of cardiovascular endpoints or survival. In contrast to other patient groups, patients with severe chronic kidney disease, especially those on dialysis, seem to derive limited benefit from this lower dose of atorvastatin.

- BACKGROUND: Treatment at stroke units is superior to treatment at other types of wards. The objective of the present study is to determine the effect size of stroke unit care in subgroups of patients with stroke. This information might be useful in a formal priority setting. METHODS: All acute strokes reported to the Swedish Stroke Register from 2001 through 2005 were followed until January 2007. The subgroups were age (18-64, 65-74, 75-84, 85+ years and above), sex (male, female), stroke subtype (intracerebral haemorrhage, cerebral infarction and unspecified stroke) and level of consciousness (conscious, reduced, unconscious). Cox proportional hazards and logistic regression analyses were used to estimate the risk for death, institutional living or dependency. RESULTS: 105,043 patients were registered at 86 hospitals. 79,689 patients (76%) were treated in stroke units and 25,354 patients (24%) in other types of wards. Stroke unit care was associated with better long-term survival in all subgroups. The best relative effect was seen among the following subgroups: age 18-64 years (hazard ratio (HR) for death 0.53; 0.49 to 0.58), intracerebral haemorrhage (HR 0.61; 0.58 to 0.65) and unconsciousness (HR 0.70; 0.66 to 0.75). Stroke unit care was also associated with reduced risk for death or institutional living after 3 months. CONCLUSIONS: Stroke unit care was associated with better long-term survival in all subgroups, but younger patients, patients with intracerebral haemorrhage and patients who were unconscious had the best relative effect and may be given the highest priority to this form of care.

- In addition to extracorporeal renal replacement strategies, which in chronic kidney disease (CKD) are largely reserved for the treatment of end-stage kidney failure, conservative measures can be taken to reduce concentration, effects, or both concentration and effects of uremic retention solutes. In this overview, we will focus on those therapies, which are aimed at preventing or delaying cardio-vascular disease, retarding or halting the progression of CKD, or both. We will discuss, consecutively, inhibitors of the renin-angiotensin-aldosterone axis, beta-blockers, calcium-channel antagonists, anti-inflammatory drugs, intestinal sorbents, calcimimetics, and glitazones. Some of these approaches could lead to a therapeutic breakthrough in the future. In addition, comprehensive tables will be provided for more traditional therapeutic approaches, such as lifestyle changes and other pharmaceutical treatments.

The role of EUTox in uremic toxin research.

- In this publication, we review the activities of the European Uremic Toxin Work Group (EUTox) in the field of uremic toxin research. Founded in 1999 under the umbrella of the European Society of Artificial Organs (ESAO), and active since 2000, this group focuses essentially on questions related to solute retention and removal during chronic kidney disease, and on the deleterious impact of those solutes on biological/biochemical systems. As of January 1, 2009, the group had met 28 times; it organized the third meeting, "Uremic Toxins in Cardiovascular Disease," which took place in October 2008 in Amiens, France. The current group is composed of 25 members belonging to 23 European research institutions. As of November 1, 2008, in total 69 papers had been published to which at least two different research groups belonging to EUTox have contributed in a collaborative effort. Of these, 40 papers were on original research and eight were specific EUTox reviews or position statements. A website (http://www.eutox.info) summarizes all relevant information concerning the work group. EUTox also developed an interactive uremic toxin database, where concentrations of known toxins are displayed, to be used by researchers in the field. In the future, EUTox intends to continue its focus on bench to bedside research with specific consideration of proteomics, metabonomics, secretomics, and genomics.
