THE EPITHELIUM AS A TARGET IN SEPSIS

Area of Science:

• Critical care medicine
• Cell biology
• Renal medicine

Background:

• Sepsis-induced organ dysfunction is a major cause of mortality.
• Epithelial dysfunction, affecting barrier function and ion transport, is a common feature across multiple organs in sepsis.
• These epithelial alterations contribute to organ impairment even without widespread cell death.

Purpose of the Study:

• To explore the role of epithelial dysfunction in sepsis-induced organ compromise.
• To investigate epithelial injury as a source for novel biomarkers.
• To assess the potential of targeting epithelial function with therapies like blood purification.

Main Methods:

• Review of existing literature on sepsis pathophysiology and epithelial biology.
• Analysis of studies investigating epithelial biomarkers in sepsis.
• Evaluation of experimental data on blood purification in sepsis models.

Main Results:

• Sepsis universally affects epithelial barrier function and ion transport, irrespective of the specific organ.
• Epithelial injury markers show promise for early detection and outcome prediction in sepsis.
• Blood purification strategies targeting sepsis-induced changes are under investigation.

Conclusions:

• Epithelial dysfunction is a critical, unifying pathophysiological event in sepsis-induced organ dysfunction.
• Further research is needed to understand epithelial cell responses, adaptation, and inter-organ crosstalk in sepsis.
• Targeting epithelial pathways and utilizing blood purification hold potential for future sepsis therapies.
