Randomized Controlled Trial Comparative Study
Removal of humoral mediators and the effect on the survival of septic patients by hemoperfusion with neutral microporous resin column.
The aim of this study is to evaluate the impact of neutral microporous resin hemoperfusion on hemodynamic improvement, removal of inflammatory cytokines, and mortality in critical care patients with severe sepsis. Forty-four patients with severe sepsis or septic shock were randomized to HA type hemoperfusion treatment (N=24) or standard therapy (N=20). Those undergoing hemoperfusion treatment received HA330 hemoperfusion. ⋯ There was no significant difference between the groups in 28-day mortality, hospital mortality, or length of hospital stay, but ICU mortality and the length of ICU stay in the HA group were markedly reduced. Hemoperfusion treatment using the HA type cartridge in sepsis is safe and it may improve organ dysfunction, ICU mortality, and shorten the length of ICU stay. Clinical significant removal of inflammatory cytokines such as IL-6 and IL-8 from circulation by hemoperfusion may contribute to improving a patient's outcome in an ICU.

Incidence and clinical outcomes of acute kidney injury requiring renal replacement therapy in Japan.
No population-based studies have described the prevalence of acute kidney injury (AKI) treated with renal replacement therapy (RRT) in Japan. This study prospectively examined the incidence of AKI requiring RRT by surveying 16 hospitals in Shizuoka prefecture from January to October 2006. The subjects comprised 242 patients treated with RRT during the observation period. ⋯ The in-hospital mortality rate was 47.1%, paralleling the increased number of insufficient organs. Oliguria was a risk factor for in-hospital mortality. These findings suggest that the incidence of AKI treated with RRT in Japan is comparable to those in Western countries, and the prognosis of AKI patients requiring RRT is also poor in Japanese patients.

The Japanese Society for Dialysis Therapy (JSDT) guideline committee, chaired by Dr Y. Tsubakihara, presents the Japanese guidelines entitled "Guidelines for Renal Anemia in Chronic Kidney Disease." These guidelines replace the "2004 JSDT Guidelines for Renal Anemia in Chronic Hemodialysis Patients," and contain new, additional guidelines for peritoneal dialysis (PD), non-dialysis (ND), and pediatric chronic kidney disease (CKD) patients. Chapter 1 presents reference values for diagnosing anemia that are based on the most recent epidemiological data from the general Japanese population. ⋯ Chapter 7 discusses adverse reactions to ESA therapy. Of particular concern is the emergence and exacerbation of hypertension associated with rapid hematopoiesis due to ESA therapy. The treatment of renal anemia in pediatric CKD patients is discussed in Chapter 8; it is fundamentally the same as that in adults.

Advanced glycation end products (AGE) are significantly increased in end-stage renal disease patients and it has been suggested that AGE accumulation is related to the progression of cardiovascular disease. An autofluorescence reader non-invasively assesses AGE accumulation using skin autofluorescence under ultraviolet light. Skin autofluorescence has been reported to be an independent predictor of mortality in Caucasian hemodialysis patients. ⋯ Each parameter was compared in patients with and without cardiovascular disease; the gender distribution, age, carotid IMT, high-density lipoprotein cholesterol, hsCRP, and skin autofluorescence were significantly related to the presence of cardiovascular disease. Multiple logistic regression analysis identified carotid IMT (OR 6.76), hsCRP (OR 1.41), and skin autofluorescence (OR 2.29) as significant factors for the presence of cardiovascular disease. Increased skin autofluorescence was related to the presence of cardiovascular disease in Asian (non-Caucasian) hemodialysis patients, and therefore an autofluorescence reader might have the potential to be a useful assessment of cardiovascular risk in these patients.

Unlike Goodpasture's syndrome with diffuse alveolar hemorrhage (DAH), there are scarce reports on the use of plasmapheresis for patients with a recurrence of DAH associated with antineutrophil cytoplasmic antibody (ANCA)-associated small vessel vasculitis (AAV) on hemodialysis. We report a case of a relapse of perinuclear-AAV with DAH, five months after starting hemodialysis. ⋯ We suggest that patients on hemodialysis with a relapse of AAV and DAH would benefit from the prompt initiation of apheresis in combination with aggressive immunosuppressive therapy. Pulmonary hemorrhage is not included in the current guidelines for therapeutic apheresis; therefore, we report this case and, if warranted, propose this condition to be included in the guidelines.
