Group B streptococcal arthritis in adults
The American Journal of Medicine
|May 1, 1984
Summary
Group B streptococci (Streptococcus agalactiae) are an increasing cause of septic arthritis in adults. Early diagnosis and treatment are crucial to prevent joint damage and improve outcomes.
Area of Science:
- Infectious Diseases
- Rheumatology
- Microbiology
Background:
- Group B beta-hemolytic streptococci (GBS), or Streptococcus agalactiae, are an uncommon cause of septic arthritis in adults.
- Literature review identified only 18 previously cited cases, with 8 reported since 1976.
Observation:
- Two new cases of GBS septic arthritis in adults were observed.
- The incidence of GBS septic arthritis appears to be rising.
- Risk factors include prior joint issues (30%) and immunocompromised status (30%).
- Four cases presented as probable oligoarticular GBS arthritis.
Findings:
- This study details 20 cases of GBS septic arthritis in adults.
- A significant portion of cases occurred in patients with predisposing factors.
Implications:
- Early recognition and prompt treatment of GBS septic arthritis are vital.
- While mortality was higher pre-penicillin, preventing joint destruction remains a key goal.
- Increased awareness of GBS as a cause of septic arthritis is warranted.
