PSP/reg: a new stone in sepsis biomarkers?
Full text linkABSTRACT: Rapid diagnosis, appropriate management, and time are the key factors for improving survival rate in many emergency clinical scenarios such as acute myocardial infarction, pulmonary embolism, cerebral stroke, and severe sepsis. Clinical signs and electrocardiographic, radiological, and echographic investigations associated with biomarkers usually allow a quick diagnosis in all of the above situations, except severe sepsis, in which the diagnosis in the early phases is often only presumptive. In sepsis, microbiological cultures are still considered the 'gold standard' for diagnosis, whereas the numerous biomarkers investigated are actually valuable only for patient stratification and evaluation of clinical course. In this issue of Critical Care, Que and colleagues describe the prognostic value of pancreatic stone protein/regenerating protein (PSP/reg) concentration in patients with severe infections. The data reported are interesting, but several questions about this biomarker arise, and further studies are needed to understand its role in sepsis and clinical practice
Early alterations of B cells in patients with septic shock: another piece in the complex puzzle of the immune response in sepsis
Full text linkImpairment of the inflammatory-immune response is currently accepted as a hallmark of severe sepsis even in the early stages of the disease. In this context, the alterations of the circulating B-lymphocytes have never been described in detail. The study by Monserrat and colleagues in the previous issue of Critical Care indicated that, in patients with septic shock, the B-cell compartment is early and deeply altered with different patterns in subset distribution and activation between survivors and non-survivors
Hemostasis in acute liver and kidney failure: nothing is as it seems
No full textVery little is known about the behavior of the hemostatic system in patients with acute kidney injury (AKI) associated with acute liver failure (ALF). Agarwal and colleagues show that patients who suffer from both ALF and AKI exhibit a higher degree of hemostasis impairment than those with normal renal function. Both anticoagulant and procoagulant factors were impaired. The development of AKI appears to displace the hemostatic equilibrium toward a more prothrombotic pattern
Comment on [A modified goal-directed protocol improves clinical outcome in intensive care unit patients with septic shock patients: a randomized controlled trial.]
No full textINTRODUCTION: The application in clinical practice of evidence-based guidelines for the management of patients with severe sepsis/septic shock is still poor in the emergency department, while little data are available for patients admitted to the intensive care unit (ICU). The aim of this study was to evaluate the effect of an in-hospital sepsis program on the adherence to evidence-based guidelines and outcome of patients with severe sepsis/septic shock admitted to the ICU.METHODS: This prospective observational cohort study included 67 patients with severe sepsis/septic shock admitted to a multidisciplinary ICU at a University Hospital from January 2005 to June 2007. Compliance to 5 resuscitation and 4 management sepsis interventions and in-hospital mortality were measured following an educational program on sepsis for physician and nurses of all hospital departments and hospital implementation of a specific protocol for recognition and management of patients with severe sepsis/septic shock, including an early consultation by a skilled 'sepsis team'.RESULTS: During the study period, the compliance to all 9 interventions increased from 8% to 35% of the patients (P < 0.01). The implementation of resuscitation and management interventions was associated with a lower risk of in-hospital mortality (23% vs 68% and 27% vs 68%, P < 0.01). In the latter 2 semesters, after activation of the 'sepsis team', in-hospital mortality of ICU septic shock patients decreased by about 40% compared with the previous period (32% vs 79%, P < 0.01).CONCLUSIONS: In our experience, an in-hospital sepsis program, including education of health-care personnel and process-changes, improved the adherence to guidelines and the survival rate of patients with severe sepsis/septic shock admitted to the ICU
