H3K14la drives endothelial dysfunction in sepsis-induced ARDS by promoting SLC40A1/transferrin-mediated ferroptosis.
MedComm (2020)
February 2025
Pulmonary endothelial cell (EC) activation is a key factor in acute respiratory distress syndrome (ARDS). In sepsis, increased glycolysis leads to lactate buildup, which induces lysine lactylation (Kla) on histones and other proteins. However, the role of protein lactylation in EC dysfunction during sepsis-induced ARDS remains unclear.

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.

Introduction: We investigated the extent to which demographic characteristics, clinical care aspects, and relevant biomarkers predicted sepsis-related mortality among patients transferred from a rural, low-volume emergency department (ED) to an urban, high-volume, level-2 trauma center.
Methods: We conducted an observational study among adult severe sepsis patients (N = 242) who, within a community-based regional healthcare system, presented to one of the four rural, low-volume EDs and were subsequently transferred to the urban, high-volume, level-2 trauma center, and were identified as septic at either location. We evaluated in-hospital and 30 days after discharge mortality.
Lipopolysaccharide-Neutralizing Peptide Modulates P2X7 Receptor-Mediated Interleukin-1β Release.

Lipopolysaccharide (LPS)-neutralizing peptides are emerging as new potential therapeutic modalities to treat sepsis and skin infections. Purinergic ligand-gated ion channels (P2X receptors) play a critical role in various biological processes, including inflammation. Recent drug development efforts have significantly focused on the modulation of P2X receptors.

Septic shock is a significant challenge in the management of patients with burns and traumatic injuries when complicated by infection, necessitating prompt and effective haemodynamic support. This review provides a comprehensive overview of current strategies for vasopressor and fluid management in septic shock, with the aim to optimize patient outcomes. With regard to vasopressor management, we elaborate on the pharmacologic profiles and clinical applications of catecholamines, vasopressin derivatives, angiotensin II, and other vasoactive agents.
