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
High Morning Cortisol Tied to Long-term Anxiety in Family Members of ICU Patients
A new study published in the journal Critical Care Medicine finds that a biomarker may help identify which family members will be most emotionally impacted by their loved one's ICU stay. In particular, family members who... read more
Are Biomarkers Ready for Prime Time?
Kyle Enfield, MD, speaks with John A. Kellum, MD, MCCM, about his talk presented at the 46th Critical Care Congress in Honolulu, Hawaii entitled, "Are Biomarkers Ready for Prime Time?" Dr. Kellum works as an Intensivist in... read more
Updates on Sepsis from WSC
Fourth session from the World Sepsis Congress Spotlight: Maternal and Neonatal Sepsis - Updates on Sepsis.... read more
Platelets and Multi-Organ Failure in Sepsis
Platelets have received increasing attention for their role in the pathophysiology of infectious disease, inflammation, and immunity. In sepsis, a low platelet count is a well-known biomarker for disease severity and more... read more
Translational Evidence for Two Distinct Patterns of Neuroaxonal Injury in Sepsis
Ischemic and diffuse neuroaxonal injury to the brain in experimental sepsis, human postmortem brains, and in vivo MRI suggest these two distinct lesion types to be relevant. Future studies should be focused on body fluid... read more
Biomarkers in AKI: That’s All the Story?
We would like to add to the recent editorial by McMahon on biomarkers of acute kidney injury (AKI), with a specific focus on biomarkers in the clinical setting of cardiac surgery-associated AKI (CSA-AKI). We agree with McMahon... read more
