Vertebral osteomyelitis due to Capnocytophaga
Revue Du Rhumatisme (English Ed.)
|December 1, 1995
Summary
This report details the first vertebral Capnocytophaga infection in an immunocompetent patient. Prompt diagnosis via repeat biopsy and culture led to a full recovery, highlighting the need for broad microbiological evaluation.
Area of Science:
- Infectious Diseases
- Osteomyelitis
- Microbiology
Background:
- Vertebral infections are typically associated with immunocompromised individuals.
- Capnocytophaga species are commensal oral bacteria, rarely causing invasive disease.
Observation:
- A 75-year-old immunocompetent woman presented with low back pain and declining health.
- Radiography revealed vertebral endplate erosions (L3-L4) without disc involvement; MRI confirmed a normal intervertebral disc.
Findings:
- Repeat vertebral biopsy and targeted bacteriologic cultures in a CO2-enriched atmosphere were crucial for identifying Capnocytophaga.
- The patient experienced a complete recovery following appropriate treatment.
Implications:
- This case expands the spectrum of Capnocytophaga infections to include vertebral osteomyelitis in immunocompetent hosts.
- Clinicians should consider Capnocytophaga in suspected bone infections, evaluating oral portals of entry and employing comprehensive microbiological studies.
