Streptococcus pneumoniae spinal infection in Nottingham, United Kingdom: not a rare event.

Pneumonia and meningitis are the most frequent manifestations of Streptococcus pneumoniae infection. Spinal infection is considered to be a rarity. Between 1985 and 1997, 8 patients with spinal infection (vertebral osteomyelitis, 3; spinal epidural abscess, 1; both, 4) due to S. pneumoniae were seen at University Hospital (Nottingham, U.K.). Predisposing factors for pneumococcal infection were documented for five patients and included diabetes mellitus, alcoholism, and corticosteroid therapy. One patient presented with concomitant meningitis and endocarditis. Clinical features of note were prolonged symptoms and a lack of febrile response. S. pneumoniae was isolated from the blood of five patients. Magnetic resonance imaging was used to localize the spinal infection in five patients. Two cases were managed medically. Three patients died after a protracted illness. A literature search revealed 20 other cases of spinal infections due to S. pneumoniae. The salient features of the cases are summarized.
