[Lemierre's syndrome: a report of six cases].

Objective: Lemierre's syndrome is a rare but severe condition combining pyrexia, cervical pain and pulmonary signs following a pharyngeal infection, usually tonsillitis. This infectious disease is still present in our country despite wide use of antibiotic therapy in pharyngeal infections.

Methods: In a retrospective study conducted between 1995 and 2000 in two departments (infectious diseases and critical care unit) of Nice university hospital (Nice, France), we collected and analysed six cases of Lemierre's syndrome.

Results: We describe a serie of 6 cases, all of them female patients of mean age 27. We enrolled healthy patients whose initial symptom was tonsillitis. Most of these patients showed signs of severe sepsis and one died of septic shock. All the others recovered with treatment. The mean time between tonsillitis and first sign of sepsis was seven days. In four cases, patients received a beta- lactam antimicrobial agent with metronidazole. In two cases, patients were treated with amoxicillin-clavulanate. All patients were investigated for the presence of internal jugular vein thrombosis and were treated by anticoagulants when research was positive.

Conclusions: A strong presumptive diagnosis can be made on the basis of clinical presentation, secondarily confirmed by para-clinical data. The prognosis depends on the speed and quality of management. We therefore wished to raise awareness of this condition among our colleagues by reporting our personal experience.
