Revisiting the Problem of Finding Effective Sepsis Treatment Solutions

Area of Science:

• Microbiology
• Pharmacology
• Immunology

Background:

• Sepsis remains a critical global health challenge.
• Pseudomonas aeruginosa is a common cause of hospital-acquired infections and sepsis.
• Effective therapeutic strategies for sepsis are urgently needed.

Purpose of the Study:

• To evaluate the efficacy of a novel preparation containing ultralow doses of formic aldehyde.
• To assess the impact of this preparation on experimental sepsis induced by Pseudomonas aeruginosa in a murine model.

Main Methods:

• Induction of experimental sepsis in C57BL/6 male mice using two strains of Pseudomonas aeruginosa (1623 and 5266).
• Administration of a preparation with ultralow doses of formic aldehyde.
• Microscopy and quantitative bacteriological analyses of blood and organ homogenates.
• Assessment of animal survival and organ histology (lungs, liver, kidneys, spleen, adrenal glands).

Main Results:

• 100% survival rate observed in the treated group of mice.
• Preservation of normal histological structure in key organs.
• Significant reduction in bacterial load in blood and tissues within hours post-infection.
• Complete eradication of bacteria by day 7 post-infection.

Conclusions:

• Ultralow doses of formic aldehyde exhibit potent therapeutic effects against experimental Pseudomonas aeruginosa sepsis.
• The preparation effectively reduces bacterial burden and prevents organ damage.
• These findings support the potential of formic aldehyde-based treatments for sepsis management.
