- Myeloperoxidase (MPO), which is secreted during activation of neutrophils, may serve as one mechanistic link among persistent inflammation, oxidative stress, and cardiovascular disease. This study related MPO activity to inflammatory and oxidative stress biomarkers, comorbidity, and ongoing medication in prevalent hemodialysis (HD) patients. In a cross-sectional evaluation of 115 prevalent (vintage 25 mo) HD patients (62 men; 63 +/- 1 yr), data on comorbidity (Davies score), diabetes, medication (statins and antiltypertensive drugs), nutritional status (subjective global assessment), blood lipids (cholesterol, HDL cholesterol, and triglycerides), inflammatory biomarkers (serum albumin, C-reactive protein, TNF-alpha, and IL-6), oxidative stress biomarkers (pentosidine, 8-hydroxydeoxyguanosine, and MPO activity) were recorded. Patients with MPO activity greater than the median had significantly (P < 0.05) lower serum albumin levels (33.2 +/- 0.7 versus 35.0 +/- 0.5 g/L), higher 8-hydroxydeoxyguanosine levels (1.26 +/- 0.08 versus 1.05 +/- 0.06 ng/mb, and a lower prevalence of statin treatment (18 versus 36%). Therefore, the median MPO activity was significantly (P < 0.05) lower (17.7 versus 26.6 Delta OD630/min per mg protein) in the subgroup of 31 HD patients with ongoing statin treatment. In a multiple regression model, correction for the impact of age, gender, vintage, serum cholesterol, serum albumin, comorbidity, diabetes, and statin use, only diabetes (P < 0.01) and statin use (P < 0.01) were significantly associated to MPO activity. Fourteen patients who had diabetes and were receiving statin treatment had markedly (P = 0.001) lower median (19.9 versus 41.2 Delta OD630/min per mg protein) MPO activity compared with 18 who had diabetes and were not taking statins. This cross-sectional study suggests that both diabetes and statin treatment affect MPO activity in prevalent HD patients.

- 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.
