The endothelium in intensive care

Area of Science:

• Vascular biology and pathophysiology
• Endothelial cell function
• Systemic inflammation and critical illness

Background:

• The vascular endothelium normally acts as an antithrombotic surface.
• Inflammation disrupts endothelial homeostasis, leading to a prothrombotic state.
• Endothelial dysfunction is implicated in multi-organ failure during severe diseases like sepsis.

Purpose of the Study:

• To review the critical role of the vascular endothelium in metabolic, vascular, and coagulation processes.
• To highlight the transition of the endothelium from an antithrombotic to a prothrombotic interface during inflammation.
• To underscore the therapeutic challenges in improving endothelial function in sepsis.

Main Methods:

• Literature review of pathophysiological processes.
• Analysis of endothelial cell activation in inflammatory conditions.
• Synthesis of information on sepsis-induced multi-organ failure.

Main Results:

• The endothelium plays a central role in metabolism, vascular tone, and hemostasis.
• Inflammation triggers endothelial activation, promoting thrombosis and inflammation.
• Dysfunctional endothelium is a key factor in sepsis-related multi-organ failure.

Conclusions:

• Understanding endothelial pathophysiology is vital for managing sepsis.
• Targeting endothelial function represents a critical therapeutic avenue for sepsis.
• Improving endothelial function remains a significant challenge in sepsis treatment.
