[Let us not forget the Lemierre's Syndrome.]

Area of Science:

• Infectious Diseases
• Microbiology
• Vascular Surgery

Background:

• Lemierre's syndrome, characterized by internal jugular vein septic thrombophlebitis, is a severe sequela of pharyngitis.
• Historically common and fatal, its incidence decreased with antibiotics, leading to its designation as a "forgotten disease".
• A notable resurgence has been observed since the 1990s, necessitating renewed clinical awareness.

Purpose of the Study:

• To highlight the re-emerging threat of Lemierre's syndrome.
• To emphasize the importance of early diagnosis and treatment in pharyngitis workups.
• To underscore the role of Gram-negative anaerobic bacteria, particularly Fusobacterium necrophorum.

Main Methods:

• Review of historical and recent clinical data on Lemierre's syndrome.
• Analysis of causative pathogens, focusing on Fusobacterium necrophorum.
• Discussion of diagnostic challenges and treatment protocols.

Main Results:

• Gram-negative anaerobic bacteria, primarily Fusobacterium necrophorum, are the main implicated pathogens.
• The syndrome, though uncommon, requires a high index of suspicion for timely diagnosis.
• Prompt and appropriate antimicrobial therapy is essential for favorable outcomes.

Conclusions:

• Clinicians must maintain awareness of Lemierre's syndrome due to its potential severity and resurgence.
• Early recognition and aggressive management, including targeted antimicrobial therapy, are critical.
• Understanding the microbiology and clinical presentation is key to combating this potentially fatal condition.
