- Background: The primary aim of this study was to assess whether a fixed protocol, using a specially trained team, for intermediate follow-up to fulfillment of guideline targets is non-inferior to conventional follow-up in the care of uraemic patients. A secondary aim was to investigate possible impact on patient outcome.Methods: The cohort comprised 424 patients from seven centers. Inclusion criteria were either serum creatinine exceeding 200 mu mol/l or calculated clearance below 30 ml/min, representing CKD 4 or 5a. Six centers followed a standardized protocol (group 1). One center provided controls (group 2). The study design was prospective and interventional. The variables measured were blood hemoglobin, bicarbonate, calcium, phosphate, intact parathyroid hormone, albumin, renal function variables, blood pressure and RAAS blockade. The number of patients achieving the set goals was analyzed as a time trend to determine if the intervention resulted in an improvement.Results: At baseline, group 1 had significantly lower GFR and higher serum creatinine, calcium, phosphate, calcium x phosphate product and bicarbonate, lower mean arterial pressure (MAP), systolic blood pressures and less use of RAAS. During the intervention, group 1 improved in the direction of guidelines for blood hemoglobin, albumin, bicarbonate and MAP. Outcome of secondary endpoints gave a risk of death of 30% in both groups, while the risk of renal replacement therapy was higher in group 1.Conclusions: However, the time to renal replacement therapy was significantly shorter in the intervention group, indicating that other variables than guideline achievements are important for the patient.

- BACKGROUND: Bacterial translocation from the gut has been suggested to induce a systemic inflammatory response syndrome (SIRS) and organ dysfunction. The liver has a pivotal role in eliminating circulating bacteria entering from the gut. We investigated whether pre-existing inflammation affects hepatic bacterial elimination.METHODS: Fifteen anaesthetised piglets were infused with E. coli in the portal vein for 3 h. The naive group (n = 6) received the bacterial infusion without endotoxin exposure. SIRS (SIRS group, n = 6) was induced by endotoxin infusion 24 h before the bacterial infusion. For effects of anaesthesia, controls (n = 3) received saline instead of endotoxin for 24 h. Bacterial counts and endotoxin levels in the portal and hepatic veins were analysed during bacterial infusion.RESULTS: The bacterial killing rate was higher in the naive group compared with the SIRS group (p = 0.001). The ratio of hepatic to portal venous bacterial counts, i.e. the median bacterial influx from the splanchnic circulation, was 0.06 (IQR 0.01-0.11) in the naive group and 0.71 (0.03-1.77) in the SIRS group at 3 h, and a magnitude lower in the naive group during bacteraemia (p = 0.03). Similar results were seen for hepatic endotoxin elimination. Peak log tumour necrosis factor alpha was higher in the naive 4.84 (4.77-4.89) vs. the SIRS group 3.27 (3.26-3.32) mg/L (p < 0.001).CONCLUSIONS: Our results suggest that hepatic bacterial and endotoxin elimination is impaired in pigs with pre-existing SIRS while the inflammatory response to bacterial infusion is diminished. If similar mechanisms operate in human critical illness, the hepatic elimination of bacteria from the gut could be impaired by SIRS.

- Background: Patients with chronic kidney disease (CKD) often suffer from iron deficiency anemia necessitating treatment with intravenous iron. This study was designed to assess the safety of iron isomaltoside 1000 (Monofer) in CKD patients. The secondary objective was to assess its effect on iron deficiency anemia. Methods: This open-label, noncomparative, multi-center trial assigned 182 patients with CKD (n=161 in dialysis and n=21 in predialysis) to iron isomaltoside 1000 either as 4 intravenous bolus injections of 100-200 mg iron per dose or as a fast high-dose infusion at baseline. Patients were generally undergoing erythropoiesis-stimulating agent (ESA) treatment (82%), and the dosage was to be kept constant during the trial. They were either switched from an existing parenteral maintenance therapy (n=144) or were not currently being treated with parenteral iron (n=38). Frequency of adverse events (AEs) and changes in markers of iron deficiency anemia were measured during 8 weeks from baseline. Results: Nineteen treatment-related AEs occurred in 13 patients (7.1%) and after 584 treatments (3.3%). No anaphylactic or delayed allergic reactions were observed. There were no clinically significant changes in routine clinical laboratory tests or vital signs. Hemoglobin increased from 99.2 g/L (SD=9.0) at baseline to 111.2 g/L (SD=14.7) at week 8 in patients not currently treated with parenteral iron (p<0.001) and increased slightly or stabilized in patients in maintenance therapy. S-Ferritin, s-iron and transferrin saturation increased significantly at all visits. Conclusions: Iron isomaltoside 1000 was clinically well tolerated, safe and effective. This new intravenous iron may offer a further valuable choice in treating the anemia of CKD.

- Early secondary sepsis (ESS), occurring after recent inflammatory activation is associated with a reduced inflammatory response. If this attenuation also is associated with decreased bacterial killing, the need for antibiotic efficacy might be greater than in primary sepsis (PS). This prospective, randomised interventional study compares bacterial killing in ESS and PS in a large animal intensive care sepsis model. 38 pigs were intravenously administered live Escherichia coli for 3 h. Before baseline ESS was pre-exposed to endotoxin 24 h, whereas PS was not. Bacterial growth was measured in organs immediately post-mortem, repeatedly during 6 h in blood in vivo and for blood intrinsic bactericidal capacity ex vivo. Splenic growth was lower in ESS animals, than in PS animals (3.31 ± 0.12, vs. 3.84 ± 0.14 log10 CFU/mL, mean ± SEM) (p < 0.01) with a similar trend in hepatic growth (p = NS). Blood bacterial count at 2 h correlated with splenic bacterial count in ESS (ESS: r = 0.71, p < 0.001) and to blood killing capacity in PS (PS: r = 0.69, p < 0.001). Attenuated inflammation in ESS is associated with enhanced antibacterial capacities in the spleen. In ESS blood bacterial count is related to splenic killing and in PS to blood bactericidal capacity. The results suggest no increased need for synergistic antibiotic combinations in ESS.
