[Postanginal sepsis caused by Fusobacterium necrophorum: Lemierre syndrome]

Postanginal sepsis or Lemierre's syndrome is characterised by septic thrombophlebitis of the jugular vein, metastatic abscesses in the lungs, soft tissues, joints or elsewhere, occurring several days to two weeks after tonsillitis or pharyngitis. The primary pathogen is a Gram-negative anaerobic rod, mostly Fusobacterium necrophorum. Previously healthy, young adults are affected mainly and the syndrome was seen more frequently in the pre-antibiotic era than it is nowadays. In the three young patients described here, a girl aged 15 and two boys aged 18 and 16, F. necrophorum was isolated from blood or pus. Histories and examinations were suggestive of Lemierre's syndrome. Ultrasound and CT scanning of the neck and other localisations proved to be important diagnostic tools in assessing the diagnosis. Response to therapy was slow and depended in at least one case on adequate drainage of abscesses. If the syndrome is suspected, initial antibiotic treatment should provide adequate coverage of anaerobic bacteria. In previously healthy patients with chills and fever occurring several days after a sore throat, Lemierre's syndrome should be considered.
