Severe sepsis-associated acute kidney injury and outcomes: a longitudinal cohort study.
Sepsis-associated acute kidney injury (SA-AKI) is common among patients admitted to the intensive care unit (ICU) with sepsis. ⋯ These results demonstrate an association between an index episode involving SA-AKI and the composite outcome in a defined population. Identification of this group may allow intensive nephrology follow-up and secondary prevention with the goal of mitigating the risk of progression of disease with significant economic and personal benefits.

Despite intensive clinical and scientific efforts, the mortality rate of sepsis remains high due to the lack of precise biomarkers for patient stratification and therapeutic guidance. Interleukin 40 (IL-40), a novel cytokine with immune regulatory functions in human diseases, was elevated at admission in two independent cohorts of patients with sepsis. High levels of secreted IL-40 in septic patients were positively correlated with PCT, CRP, lactate (LDH), and Sequential Organ Failure Assessment (SOFA) scores, in which IL-40 levels were used to stratify the early death of critically ill patients with sepsis. ⋯ Clinically, the IL-40 level was positively correlated with the NET-related MPO/dsDNA ratio in septic patients. Finally, with antibiotics (gentamycin), genetic knockout of IL-40 prevented polymicrobial sepsis fatalities more efficiently than without gentamycin treatment. In summary, these data reveal a novel prognostic strategy for sepsis and that IL-40 may serve as a novel therapeutic target for sepsis.

Ultrasonographic optic nerve sheath diameter (ONSD) is a satisfactory noninvasive intracranial pressure (ICP) monitoring test. Our aim was to evaluate ONSD as an objective screening tool to predict and diagnose ICP changes early in sepsis-associated encephalopathy (SAE). ⋯ ONSD could be an objective screening method for early diagnosis of SAE, with a cutoff > 5.2 mm. Trial registration NCT05849831 ( https://clinicaltrials.gov/study/NCT05849831 ).

Recent studies have proposed that Krebs cycle metabolites may serve as potential biomarkers for prognosis in sepsis. However, whether these metabolites are associated with disease severity and can be applied to improve the effectiveness of current prognosis assessment in sepsis remains unclear and is explored in this study. ⋯ Study findings indicate that Krebs cycle metabolites, particularly alpha-ketoglutarate, fumarate, and malate, when applied with SOFA score, might enhance prognostic assessment in patients with sepsis.
