Abstract:
Over a period of 12 months 3 patients presented with severe tonsillitis and subsequently grew Fusobacterium necrophorum (literally-spindle-shaped rod which brings death!) from blood cultures. Two patients responded well to antibiotics and were discharged within 4 days of admission. The third case had a longer history of symptoms and following investigations of a minor but unusual neck swelling was found to have thrombosis of the external and internal jugular vein. This is the first stage in the potentially fatal dissemination of this virulent organism which manifests clinically as Lemierre's syndrome. We describe the clinical histories and discuss whether cases are unrecognised because of the prompt clinical response to penicillin and metronidazole. We stress the importance of taking blood cultures and careful examination of the neck in all patients presenting with a severe tonsillitis.
Insights
Fusobacterium necrophorum can cause severe tonsillitis and Lemierre's syndrome. Early recognition and blood cultures are crucial for diagnosing this potentially fatal infection, even with prompt antibiotic response.
Area of Science:
- Infectious Diseases
- Microbiology
- Vascular Medicine
Background:
- Severe tonsillitis can be a precursor to serious systemic infections.
- Fusobacterium necrophorum is a bacterium that can cause severe throat infections.
Observation:
- Three patients with severe tonsillitis grew Fusobacterium necrophorum in blood cultures over 12 months.
- One patient developed external and internal jugular vein thrombosis, indicative of Lemierre's syndrome.
Findings:
- Two patients with Fusobacterium necrophorum tonsillitis responded rapidly to antibiotics.
- The third patient, with a longer symptom history, presented with jugular vein thrombosis, a critical step in disease dissemination.
Implications:
- Lemierre's syndrome may be underdiagnosed due to rapid clinical improvement with antibiotics like penicillin and metronidazole.
- Emphasizes the importance of blood cultures and neck examination in severe tonsillitis cases.
- Highlights the potential severity of Fusobacterium necrophorum infections beyond typical pharyngitis.
