Immunopathophysiology of human sepsis

Area of Science:

• Immunology
• Pathophysiology
• Microbiology

Background:

• Sepsis is a major global health issue, defined as life-threatening organ dysfunction from a dysregulated host response to infection.
• Current understanding of sepsis immune mechanisms reveals a complex interplay of hyperinflammation and immune suppression.
• Existing definitions of sepsis may not fully capture the intricate immune processes involved.

Purpose of the Study:

• To review the immunopathogenesis of sepsis.
• To highlight recent pathophysiological findings expanding sepsis knowledge.
• To explore the role of sepsis endotypes and the gut microbiome in immune response.

Main Methods:

• Literature review of immunopathogenesis in sepsis.
• Analysis of recent pathophysiological findings.
• Synthesis of evidence on sepsis endotypes and gut microbiome.

Main Results:

• Sepsis involves simultaneous hyperinflammation and immune suppression.
• Sepsis endotypes represent distinct immune profiles and patient outcomes.
• The gut microbiome plays a significant role in sepsis immunity.

Conclusions:

• Further research into sepsis immunopathogenesis is crucial.
• Translating molecular insights into effective sepsis therapies remains a challenge.
• Understanding sepsis endotypes and microbiome interactions may lead to improved patient outcomes.
