Summary
Systemic inflammatory response syndrome (SIRS) and sepsis are leading causes of death in critically ill patients. This review clarifies definitions and pathophysiology, aiming to guide future treatment development for better patient outcomes.
Area of Science:
- Critical care medicine
- Pathophysiology
- Clinical definitions
Background:
- Sepsis and SIRS significantly contribute to mortality in intensive care units.
- Understanding the pathogenesis is advancing, yet novel treatments have underperformed.
- Existing treatments have not met expectations from preclinical studies.
Purpose of the Study:
- To define current criteria for SIRS, sepsis, and septic shock.
- To review the underlying pathophysiology of these critical conditions.
- To provide a foundation for developing more effective therapeutic strategies.
Main Methods:
- Literature review of current definitions.
- Synthesis of current knowledge on pathophysiology.
- Analysis of discrepancies between preclinical and clinical outcomes.
Main Results:
- Established definitions for SIRS, sepsis, and septic shock are presented.
- Key pathophysiological pathways are detailed.
- The gap between animal model promise and clinical trial results is highlighted.
Conclusions:
- Clear definitions and a solid grasp of pathophysiology are crucial.
- Further research is needed to bridge the gap between preclinical findings and clinical efficacy.
- Improved understanding may lead to more successful novel treatments for sepsis and SIRS.
