Subtypes and Mimics of Sepsis

Area of Science:

• Critical Care Medicine
• Infectious Diseases
• Clinical Diagnostics

Background:

• Sepsis is a complex syndrome with diverse phenotypes, necessitating targeted therapies for specific patient subsets.
• Current sepsis management may overlook treatable conditions that mimic sepsis due to commonality and confirmation bias.

Purpose of the Study:

• To emphasize the importance of identifying sepsis mimics and treatable diseases presenting as sepsis.
• To guide clinicians in differentiating typical sepsis from other conditions causing organ failure.

Main Methods:

• Review of clinical presentation and diagnostic challenges in sepsis.
• Highlighting the role of comprehensive medical and family history.
• Emphasizing focused diagnostic testing and subspecialty consultation.

Main Results:

• Sepsis is often heterogeneous, with some phenotypes responding to specific treatments.
• Confirmation bias can lead to overlooking unusual causes of organ failure.
• Thorough patient evaluation can uncover treatable diseases masquerading as sepsis.

Conclusions:

• Developing novel sepsis therapies requires focusing on distinct patient subpopulations.
• Identifying and treating conditions that mimic sepsis is essential for improving patient outcomes.
• Attention to history, diagnostics, and expert consultation aids in diagnosing rare, treatable causes of organ dysfunction.
