Interaction Between Altered Gut Microbiota and Sepsis: A Hypothesis or an Authentic Fact?

Area of Science:

• Microbiology
• Immunology
• Public Health

Background:

• Sepsis is a major global cause of mortality, responsible for 25% of hospital deaths.
• Gut microbiota plays a dominant role in sepsis development, alongside immune system dysregulation.
• The human microbiome, particularly gut microbiota, significantly impacts overall health.

Purpose of the Study:

• To review and analyze existing studies on the association between gut microbiota and sepsis.
• To provide a comprehensive understanding of the relationship between microbiota alterations and sepsis.
• To highlight the clinical and research significance of gut microbiota in sepsis.

Main Methods:

• Extensive literature search conducted across multiple scientific databases.
• Analysis of studies focusing on the gut microbiome's role in sepsis.
• Synthesis of findings regarding microbiota composition, metabolites, and immune responses in sepsis.

Main Results:

• Dysbiosis, an imbalance in gut microbiota, is closely associated with altered immune responses in sepsis.
• Gut microbiota metabolites, such as short-chain fatty acids, are linked to various illnesses, including sepsis.
• The gut microbiota holds a unique position in understanding and potentially treating sepsis.

Conclusions:

• The gut microbiota is a critical factor in sepsis pathogenesis.
• Further research into the microbiota-sepsis axis can lead to novel therapeutic strategies.
• Understanding the human microbiome's influence is essential for public health initiatives targeting sepsis.
