Comparative Study
Renal anemia: comparing current Eastern and Western European management practice (ORAMA).
The Optimal Renal Anaemia Management Assessment trial prospectively examined the impact of implementing European Best Practice Guidelines on outcomes in the management of renal anemia. Baseline data give an insight to standards of clinical care and provide a basis for a future comparison of guideline target attainment with final results. Fifty-three centers from eight European countries enrolled 739 patients with stage II-V chronic kidney disease who were either anemic (hemoglobin <11 g/dL) or treated with erythropoiesis-stimulating agents and/or iron supplementation. ⋯ The guideline ferritin target was achieved by 85% of dialysis and 52% of non-dialysis patients; 81% of dialysis and 78% of non-dialysis patients attained the transferrin saturation target. Most patients (96%) were receiving erythropoiesis-stimulating agents. Anemia management in patients with chronic kidney disease shows considerable regional differences across Europe, and target attainment remains suboptimal in many European nephrology centers after the revised 2004 guidelines.

Comparative Study
Adjuvant hyperbaric oxygen therapy in the treatment of hemodialysis patients with chronic osteomyelitis.
Hemodialysis dependence is an independent risk factor for hematogenous complication, including distant metastatic infection and osteomyelitis. Chronic osteomyelitis is a serious disease that fails to respond to aggressive medical and surgical treatment. Hyperbaric oxygen therapy has been proved to enhance bone and soft tissue healing in many studies. This article presents the preliminary result of hyperbaric oxygen therapy in hemodialysis-dependent patients with chronic osteomyelitis. ⋯ Hyperbaric oxygen is effective as an adjunct to aggressive medical and surgical treatment in chronic refractory osteomyelitis among hemodialysis-dependent patients.

Acute kidney injury (AKI) occurs frequently after cardiac surgery. Although numerous variables were identified as predictors for AKI, there is a lack of information about possible differences in risk factors according to the level of preoperative renal function. Preoperative, intraoperative, and postoperative data from 4118 adult patients submitted to cardiac surgery from January 1, 2000, to December 31, 2005, were included in the study. ⋯ In conclusion, the present study demonstrated a difference in variables associated with postoperative AKI, according to baseline renal function. The degree of preoperative renal function was a predictor of AKI only in patients with CKD stages 3-4, as well as other risk factors. In addition to other well known risk factors for AKI in this setting, the use of diuretics in patients of group 1 and the level of hemodilution during CPB in both groups should be emphasized, as they are potentially modifiable.

Randomized Controlled Trial Comparative Study
The comparative safety of various intravenous iron preparations in chronic kidney disease patients.
The relative safety of parenteral iron preparations is a controversial issue in the management of anemia in chronic kidney disease (CKD), as direct head-to-head comparative trials are lacking. In this study, patients of CKD were randomized to receive intravenous low molecular weight iron dextran (ID), sodium ferrigluconate complex (SFGC), and iron sucrose (IS) at doses and infusion rates recommended by the product manufacturer. One time test dose was used only for ID and SFGC. ⋯ No significant difference was seen between the three groups in terms of non-serious ADEs. Drug discontinuation occurred significantly more often with ID. One patient who developed anaphylactoid reaction with SFGC and ID tolerated iron sucrose well.

Comparative Study
Positive correlation of CRP and fibrinogen levels as cardiovascular risk factors in early stage of continuous ambulatory peritoneal dialysis patients.
We aimed to study the relationship between the C-reactive protein (CRP), albumin, and fibrinogen as cardiovascular risk factors in continuous ambulatory peritoneal dialysis (CAPD) patients, in the early stage of their therapy. The study included 21 CAPD patients as the study group (SG) and age- and sex-matched 21 healthy patients as the control group (CG). History and physical exam data were obtained for all cases, and demographic baseline characteristics were taken. ⋯ When patients with and without cardiovascular disease (CVD) were compared, no correlation was seen between CRP and other parameters. A positive correlation of CRP and fibrinogen levels as cardiovascular risk factors was shown in early stage of CAPD patients. The CAPD patients with elevated levels of CRP and fibrinogen should receive close follow-up for cardiovascular disease prevention.
