An alternate pathophysiologic paradigm of sepsis and septic shock: implications for optimizing antimicrobial therapy

Area of Science:

• Infectious Diseases
• Critical Care Medicine
• Pharmacology

Background:

• Antimicrobial therapy revolutionized serious infection treatment, but pathogen evolution limits current septic shock drug effectiveness.
• Despite extensive research, novel non-antimicrobial sepsis therapies have shown limited clinical progress.
• The current understanding of septic shock may overlook the microbial burden's primary role in organ dysfunction.

Purpose of the Study:

• To explore the hypothesis that the microbial burden is the primary driver of septic organ dysfunction.
• To propose an alternate pathophysiologic paradigm for septic shock.
• To identify key areas for optimizing antimicrobial therapy and improving septic shock outcomes.

Main Methods:

• Review of existing literature on septic shock pathophysiology and antimicrobial therapy.
• Analysis of the limitations of current treatment paradigms.
• Development of an alternate model emphasizing microbial burden and antimicrobial delivery.

Main Results:

• The current pathophysiologic paradigm may not adequately address the microbial burden's role in septic shock.
• An alternate paradigm suggests improved antimicrobial delivery and enhanced antimicrobial cidality are crucial.
• Timely administration of antimicrobials is critical for improving septic shock outcomes.

Conclusions:

• Improving the delivery of existing antimicrobials and anti-infectious strategies may be key to better septic shock outcomes.
• Focusing on antimicrobial efficacy and minimizing treatment delays are essential.
• A paradigm shift recognizing the primacy of microbial burden is needed for therapeutic advancement.
