Elevated serum IL-37 concentrations in patients with sepsis

Area of Science:

• Immunology
• Critical Care Medicine
• Biochemistry

Background:

• Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection.
• Understanding the role of specific cytokines, such as Interleukin-37 (IL-37), is crucial for managing sepsis.
• The inflammatory response in sepsis is complex and involves numerous signaling pathways.

Purpose of the Study:

• To investigate the changes and significance of Interleukin-37 (IL-37) levels in patients with sepsis.
• To explore the correlation between IL-37 and the inflammatory reaction in sepsis.
• To assess the potential role of IL-37 as a therapeutic target in sepsis management.

Main Methods:

• Serum samples were collected from 50 sepsis patients and 30 healthy controls.
• Interleukin-37 (IL-37) levels were measured using enzyme-linked immunosorbent assay (ELISA) on day 1 and day 7.
• Correlation analysis was performed to assess the relationship between IL-37, IL-1β, and inflammatory severity.

Main Results:

• Serum IL-37 levels were significantly higher in sepsis patients on day 1 compared to healthy controls (P < .05).
• IL-37 levels decreased after treatment but without statistical significance (P > .05).
• A positive correlation was observed between serum IL-37 and IL-1β levels.

Conclusions:

• Elevated IL-37 levels in sepsis patients are associated with the severity of the inflammatory response.
• IL-37 may play a role in controlling sepsis by suppressing pro-inflammatory cytokine production.
• Further research is warranted to explore IL-37's therapeutic potential in sepsis.
