Comparison of Diagnostic Accuracy Among Procalcitonin, C-reactive protein, and Interleukin 6 for Blood Culture Positivity in General ICU Patients
Despite various technological advances, it still usually takes at least 24 to 48 h to obtain a blood culture result. The subsequent delays in diagnosis and treatment of infection can negatively impact care in the intensive... read more
Derivation and Validation of Plasma Endostatin for Predicting Renal Recovery from AKI
Plasma endostatin shows a useful value for predicting failure to recover from acute kidney injury (AKI). The predictive ability can be greatly improved when endostatin is combined with the Sequential Organ Failure Assessment... read more
Phenotyping: Need to Identify Subgroups of ARDS Patients
The consensus definitions of acute respiratory distress syndrome (ARDS) mainly rely on feasible clinical criteria, which help to group patients together for inclusion in clinical trials and for clinical management. This generates... read more
Combined Biomarkers Predict Acute Mortality Among Critically Ill Patients With Suspected Sepsis
Combined biomarkers predict risk for 14-day and total mortality among subjects with suspected sepsis. Serum amyloid P and tissue plasminogen activator demonstrated the best discriminatory ability in this cohort. Fourteen-day... read more
Immunotherapy Effects on Sepsis
A randomised controlled multicentre trial assessed for the first time the safety and pharmacokinetics of an antiprogrammed cell death-ligand 1 (anti–PD-L1) immune checkpoint inhibitor (BMS-936559; Bristol-Myers Squibb,... read more
Neutrophil Extracellular Traps Are Elevated in Patients with Pneumonia-related ARDS
Bronchoalveolar neutrophil extracellular trap concentration was not significantly associated with mechanical ventilation duration in pneumonia-related ARDS. The acute respiratory distress syndrome (ARDS) is the most severe... read more
New Guidelines for Hospital-acquired Pneumonia/Ventilator-associated Pneumonia
American and European guidelines have many areas of common agreement such as limiting antibiotic duration. Both guidelines were in favor of a close clinical assessment. Neither recommended a regular use of biomarkers but... read more
Surfactant protein D is a causal risk factor for COPD
Surfactant protein D (SP-D) is produced primarily in the lung and is involved in regulating pulmonary surfactants, lipid homeostasis and innate immunity. Circulating SP-D levels in blood are associated with chronic obstructive... read more
The utility of biomarkers in traumatic brain injury clinical management
Currently, TBI management is guided by clinical histories and neuroimaging techniques. While these techniques may be advanced, they are more costly than serum analysis, involve exposure to ionizing radiations, and have certain... read more
Metabolic-based Biomarkers Have Potential to Triage Children with Sepsis
A new study has validated potential biomarkers for a sepsis-triage model to distinguish sepsis patients requiring care in the pediatric intensive care unit (PICU) from sepsis identified in the pediatric emergency department... read more
The impact of age on the innate immune response and outcomes after severe sepsis/septic shock in trauma and surgical ICU patients
Aged, critically ill surgical patients have greater organ dysfunction and incidence of adverse clinical outcomes after sepsis. Biomarker profiles suggest an immunophenotype of persistent immunosuppression and catabolism.... read more
Blood test may obviate need for head CTs in brain trauma evaluation
A biomarker test based on the presence of two proteins in the blood appears to be suitable for ruling out significant intracranial injuries in patients with a history of mild traumatic brain injury (TBI) without the need... read more
Early PREdiction of Sepsis Using Leukocyte Surface Biomarkers
From a large panel of leukocyte biomarkers, immunosuppression biomarkers were associated with subsequent sepsis in ED patients with suspected acute infection. Between January 2014 and February 2016, we recruited 272, 59 and... read more
Viral Sepsis in Children
Sepsis in children is typically presumed to be bacterial in origin until proven otherwise, but frequently bacterial cultures ultimately return negative. Although the incidence of viral-induced sepsis is not precisely known,... read more
Circulating Biomarkers May be Unable to Detect Infection at the Early Phase of Sepsis in ICU Patients
During the study period, 363 patients with SIRS were screened, 84 having exclusion criteria. Ninety‑one patients were classified as having non‑septic SIRS and 188 as having sepsis. Eight biomarkers had an area under... read more
Temporal Biomarker Profiles and Their Association with ICU Acquired Delirium
While there are differences in markers (adiponectin and several brain proteins) between patients with and without delirium, the development of delirium is not preceded by a change in the biomarker profile of inflammatory... read more
Genomics and Pharmacogenomics of Sepsis: So Close and Yet So Far
Sapru et al. show in this issue of Critical Care that variants of thrombomodulin and the endothelial protein C receptor, but not protein C, are associated with mortality and organ dysfunction (ventilation-free and organ failure-free... read more
Biomarkers for Prediction of RRT in AKI
Acute kidney injury (AKI) frequently occurs in critically ill patients and often precipitates use of renal replacement therapy (RRT). However, the ideal circumstances for whether and when to start RRT remain unclear. We performed... read more
Evidence for Persistent Immune Suppression in Patients Who Develop Chronic Critical Illness After Sepsis
Many sepsis survivors develop chronic critical illness (CCI) and are assumed to be immunosuppressed, but there is limited clinical evidence to support this. We sought to determine whether the incidence of secondary infections... read more
Do We Need New Trials of Procalcitonin-Guided Antibiotic Therapy?
Using biomarkers as a guide to tailor the duration of antibiotic treatment in respiratory infections is an attractive hypothesis assessed in several studies. Recent work aiming to summarize the evidence assessed the effect... read more
The EM Educator Series: Sepsis in the ED
These posts provide brief mini-cases followed by key questions to consider while working. The featured questions provide important learning points for those working with you, as well as vital items to consider in the evaluation... read more
Urinary Oxygenation as a Surrogate Measure of Medullary Oxygenation During Angiotensin II Therapy in Septic AKI
In septic acute kidney injury (AKI), renal medullary and urinary hypoxia developed several hours before increases in currently used biomarkers. Angiotensin II transiently improved renal function without worsening medullary... read more
