Patients with chronic kidney disease are at high risk for sepsis and sepsis-related mortality. ⋯ Use of statins was strongly and independently associated with a reduction in the risk of sepsis events [corrected] in patients who had chronic kidney disease and were receiving dialysis. Randomized trials of statins in patients with chronic kidney disease should examine the prevention of sepsis as a potentially important benefit.

Multicenter StudyAdrenal function in sepsis: the retrospective Corticus cohort study.
To refine the value of baseline and adrenocorticotropin hormone (ACTH)-stimulated cortisol levels in relation to mortality from severe sepsis or septic shock. ⋯ Although delta cortisol and not basal cortisol level was associated with clinical outcome, further studies are still needed to optimize the diagnosis of adrenal insufficiency in critical illness. Etomidate influenced ACTH test results and was associated with a worse outcome.

The International Integrated Database for the Evaluation of Severe Sepsis and Drotrecogin alfa (activated) Therapy includes an extensive cohort of surgical patients (1659/4459; 37%). This database broadens the experience reported on a comparatively small set of surgical patients from the pivotal Protein C Worldwide Evaluation in Severe Sepsis trial to examine issues of safety and efficacy in a much larger cohort. ⋯ International Integrated Database for the Evaluation of Severe Sepsis and Drotrecogin alfa (activated) Therapy analyses affirmed the favorable benefit/risk profile of DrotAA for surgical patients. The serious adverse event rate that was experienced by surgical patients during the study drug infusion period was 7.5% in the DrotAA-treated group versus 6.3% in the placebo-treated group (odds ratio, 1.41; 95% CI, 0.89-2.25). The clinical benefit of DrotAA therapy paralleled baseline risk of death and substantiated findings from the Protein C Worldwide Evaluation in Severe Sepsis study. Future analyses are needed to evaluate the special relationships among sepsis severity, bleeding management, and the postoperative timing of DrotAA administration.

This study evaluated near-infrared spectroscopy (NIRS)-derived measurements in hemodynamically stable patients with severe sepsis, as compared with similar measurements in healthy age-matched volunteers. Prospective, preliminary, observational study in a surgical intensive care unit and clinical research center at a university health center. We enrolled 10 patients with severe sepsis and 9 healthy age-matched volunteers. ⋯ Patients with severe sepsis had longer StO2 recovery times and lower NIRS-derived local oxygen consumption values versus healthy volunteers. In our preliminary study, NIRS provides a noninvasive continuous method to evaluate peripheral tissue oxygen metabolism in hemodynamically stable patients with severe sepsis. Further research is needed to demonstrate whether these values apply to broader populations of patients with systemic inflammatory response syndrome, sepsis, severe sepsis, and septic shock.
