Randomized Controlled Trial Multicenter Study Comparative Study
Intensive insulin therapy and pentastarch resuscitation in severe sepsis.
The role of intensive insulin therapy in patients with severe sepsis is uncertain. Fluid resuscitation improves survival among patients with septic shock, but evidence is lacking to support the choice of either crystalloids or colloids. ⋯ The use of intensive insulin therapy placed critically ill patients with sepsis at increased risk for serious adverse events related to hypoglycemia. As used in this study, HES was harmful, and its toxicity increased with accumulating doses. (ClinicalTrials.gov number, NCT00135473.)

Multicenter Study Clinical Trial
Expression of cell surface receptors and oxidative metabolism modulation in the clinical continuum of sepsis.
Infection control depends on adequate microbe recognition and cell activation, yet inflammatory response may lead to organ dysfunction in sepsis. The aims of this study were to evaluate cell activation in the context of sepsis and its correlation with organ dysfunction. ⋯ Surface receptors expression on neutrophils may be modulated across the continuum of sepsis, and enhanced or decreased expression may be found depending on the receptor considered. ROS generation is upregulated both in neutrophils and monocytes in septic patients, and it is differently modulated depending on the stage of the disease and the stimuli used.

Multicenter Study Comparative StudyA retrospective observational study of drotrecogin alfa (activated) in adults with severe sepsis: comparison with a controlled clinical trial.
To compare characteristics and outcomes of patients treated with drotrecogin alfa (activated) (DrotAA) in clinical practice to those treated in a phase III randomized controlled trial (PROWESS). ⋯ Patients treated in clinical practice differed from those in PROWESS. Patients were younger, had more comorbidities, had greater severity of illness, and had longer mean time from severe sepsis onset to the start of DrotAA. Hospital mortality for patients treated within 1 day of severe sepsis onset was similar to DrotAA-treated PROWESS patients. While the low number of serious bleeding events precludes a definitive assessment, the observed incidence of serious bleeding events in clinical practice patients was numerically higher than in DrotAA-treated PROWESS patients.

Randomized Controlled Trial Multicenter Study Comparative StudyThe INIS Study. International Neonatal Immunotherapy Study: non-specific intravenous immunoglobulin therapy for suspected or proven neonatal sepsis: an international, placebo controlled, multicentre randomised trial.
Sepsis is an important cause of neonatal death and perinatal brain damage, particularly in preterm infants. While effective antibiotic treatment is essential treatment for sepsis, resistance to antibiotics is increasing. Adjuvant therapies, such as intravenous immunoglobulin, therefore offer an important additional strategy. Three Cochrane systematic reviews of randomised controlled trials in nearly 6,000 patients suggest that non-specific, polyclonal intravenous immunoglobulin is safe and reduces sepsis by about 15% when used as prophylaxis but does not reduce mortality in this situation. When intravenous immunoglobulin is used in the acute treatment of neonatal sepsis, however, there is a suggestion that it may reduce mortality by 45%. However, the existing trials of treatment were small and lacked long-term follow-up data.This study will assess reliably whether treatment of neonatal sepsis with intravenous immunoglobulin reduces mortality and adverse neuro-developmental outcome. ⋯ Data will be collected at discharge from hospital and at 2 years of age (corrected for gestation) using a parental questionnaire and a health status questionnaire completed during a face-to-face follow-up appointment with the child's paediatrician.

Multicenter Study Comparative Study
Are blood transfusions associated with greater mortality rates? Results of the Sepsis Occurrence in Acutely Ill Patients study.
Studies have suggested worse outcomes in transfused patients and improved outcomes in patients managed with restricted blood transfusion strategies. The authors investigated the relation of blood transfusion to mortality in European intensive care units (ICUs). ⋯ This observational study does not support the view that blood transfusions are associated with increased mortality rates in acutely ill patients.
