Sepsis accounts for approximately one in three hospital deaths and is associated with very high health care costs due to prolonged lengths of stay in the intensive care unit and hospital. Sepsis is essentially an immunologic response to infection that is propagated systemically, leading to diffuse cellular and microcirculatory dysfunction, vasodilation, vital organ hypoperfusion, and eventual failure. This review covers the pathophysiology, stabilization/assessment, diagnosis, treatment, and disposition and outcomes of sepsis. Figures show the inflammatory and thrombotic response to infection, the action of nitric oxide on vascular smooth muscle cells, accelerated glycolysis and increased lactate production as a result of the catecholamine surge seen in septic shock, sepsis mortality associated with number of organ failures identified in the emergency department (ED), and protocolized therapy for septic shock. Tables list definitions of sepsis syndromes; frequently cited scoring systems for mortality prediction in ED patients with sepsis; Sequential Organ Failure Assessment (SOFA) score; current recommendations regarding treatment bundles at 3 and 6 hours of resuscitation; antibiotic recommendations based on suspected source; and vasopressors used in septic shock with recommended dosing, mechanism of action, and indications. This review contains 5 highly rendered figures, 6 tables, and 42 references.

AbstractEarly identification of infection severity and organ dysfunction is crucial in improving outcomes of patients with sepsis. We aimed to develop a new combination of blood-based biomarkers that can early predict 28-day mortality in patients with sepsis or septic shock. We enrolled 66 patients with sepsis or septic shock and compared 14 blood-based biomarkers in the first 24 h after ICU admission. The serum levels of interleukin-6 (IL-6) (median 217.6 vs. 4809.0 pg/ml, P = 0.001), lactate (median 2.4 vs. 6.3 mmol/L, P = 0.014), N-terminal prohormone of brain natriuretic peptide (NT-proBNP) (median 1596.5 vs. 32,905.3 ng/ml, P < 0.001), prothrombin time (PT) (median 15.6 vs. 20.1 s, P = 0.030), activated partial thrombin time (APTT) (median 45.1 vs. 59.0 s, P = 0.026), and international normalized ratio (INR) (median 1.3 vs. 1.8, P < 0.001) were significantly lower in the survivor group. IL-6, NT-proBNP, and INR provided the best individual performance in predicting 28-day mortality of patients with sepsis or septic shock. Furthermore, the combination of these three biomarkers achieved better predictive performance (AUC 0.890, P < 0.001) than conventional scoring systems. In summary, the combination of IL-6, NT-proBNP, and INR may serve as a potential predictor of 28-day mortality in critically ill patients with sepsis or septic shock.

Abstract Background The diagnostic and prognostic utility of various sepsis scores varied among different cohorts and settings. Methods A prospective cohort study in adult patients with sepsis at Siriraj Hospital (Bangkok, Thailand) was conducted during January to July 2019. The performance of sepsis assessments, including systemic inflammatory response syndrome (SIRS) score, sequential organ failure assessment (SOFA) score, quick sepsis-related organ failure assessment (qSOFA) score, modified early warning score (MEWS), and national early warning score (NEWS), for sepsis detection and mortality prediction were compared with agreement between 2 infectious disease (ID) specialists to determine their sepsis and septic shock status as the reference standard. Results Among the 470 subjects included in this study, 206 patients (43.8%) were determined by 2 ID specialists to have sepsis. Systemic inflammatory response syndrome ≥2, qSOFA ≥2, and NEWS ≥5 yielded the highest sensitivity (93.2%), specificity (81.3%), and accuracy (72.6%), respectively, for detecting sepsis. The SIRS ≥2 had the highest sensitivity (97.8%), whereas qSOFA ≥2 had the highest specificity (61%) and accuracy (69.7%) for predicting mortality among sepsis patients. Receiver operating characteristic (ROC) curve showed MEWS to have the highest discriminatory power for sepsis detection (area under the ROC curve [AUROC], 0.79; 95% confidence interval [CI], 0.74–0.83), whereas SOFA had the highest discriminatory power for predicting hospital mortality (AUROC, 0.76; 95% CI, 0.69–0.79). Conclusions The NEWS ≥5 and qSOFA ≥2 were the most accurate scoring systems for sepsis detection and mortality prediction, respectively. Each scoring system is useful for different specific purposes relative to early detection and mortality prediction in sepsis patients.

This study aimed (1) to assess the diagnostic accuracy of neutrophil-to-lymphocyte (NLR), platelet-to-lymphocyte (PLR), monocyte-to-lymphocyte (MLR) and platelet count-to-mean platelet volume (PLT/MPV) ratios in predicting septic shock in patients on admission to the intensive care unit (ICU) and (2) to compare it with the role of C-reactive protein (CRP), procalcitonin (PCT) and lactate level. We also sought (3) to verify whether the indices could be useful in ICU mortality prediction and (4) to compare them with Acute Physiology and Chronic Health Evaluation II (APACHE II), Simplified Acute Physiology Score II (SAPS II) and Sequential Organ Failure Assessment (SOFA) scores. This retrospective study covered 138 patients, including 61 subjects with multi-organ failure due to septic shock (study group) and 77 sex- and age-matched controls. Septic patients had significantly higher NLR (p < 0.01) and NLR predicted septic shock occurrence (area under the ROC curve, AUROC = 0.66; 95% CI 0.58–0.74). PLR, MLR and PLT/MPV were impractical in sepsis prediction. Combination of CRP with NLR improved septic shock prediction (AUROC = 0.88; 95% CI 0.81–0.93). All indices failed to predict ICU mortality. APACHE II and SAPS II predicted mortality with AUROC = 0.68; 95% CI 0.54–0.78 and AUROC = 0.7; 95% CI 0.57–0.81, respectively. High NLR may be useful to identify patients with multi-organ failure due to septic shock but should be interpreted along with CRP or PCT. The investigated indices are not related with mortality in this specific clinical setting.
