Background:
Although the coexistence of bacterial meningitis and arthritis has been noted in several studies, it remains unclear how often both conditions occur simultaneously.
Methods:
We evaluated the presence of arthritis in a prospective nationwide cohort of 696 episodes of community-acquired bacterial meningitis, confirmed by culture of cerebrospinal fluid, which occurred in patients aged >16 years. The diagnosis of arthritis was based upon the judgment of the treating physician. To identify differences between groups Fisher exact statistics and the Mann-Whitney U test were used.
Results:
Arthritis was recorded in 48 of 696 (7%) episodes of community-acquired bacterial meningitis in adults. Joint-fluid aspirations were performed in 23 of 48 patients (48%) and joint-fluid cultures yielded bacteria in 6 of 23 patients (26%). Arthritis occurred most frequently in patients with meningococcal meningitis (12%). Of the 48 patients with bacterial meningitis and coexisting arthritis, four died (8%) and 10 (23%) had residual joint symptoms.
Conclusion:
Arthritis is a common manifestation in patients with community-acquired bacterial meningitis. Functional outcome of arthritis in bacterial meningitis is generally good because meningococcal arthritis is usually immune-mediated, and pneumococcal arthritis is generally less deforming than staphylococcal arthritis. Nevertheless, additional therapeutic measures should be considered if clinical course is complicated by arthritis. In patients with infectious arthritis prolonged antibiotic therapy is mandatory.
Insights
Bacterial meningitis co-occurs with arthritis in 7% of adult cases. While often immune-mediated and generally having good outcomes, prolonged antibiotic therapy is crucial for infectious arthritis in bacterial meningitis.
Area of Science:
- Infectious Diseases
- Rheumatology
- Clinical Microbiology
Background:
- The simultaneous occurrence of bacterial meningitis and arthritis is recognized but not well-quantified.
- Understanding the frequency and characteristics of this dual condition is important for patient management.
Purpose of the Study:
- To determine the incidence of arthritis in adult patients with community-acquired bacterial meningitis.
- To analyze the clinical features and outcomes of bacterial meningitis with coexisting arthritis.
Main Methods:
- A prospective nationwide cohort study of 696 adult patients with culture-confirmed bacterial meningitis.
- Arthritis diagnosis was based on physician judgment; statistical analysis included Fisher exact test and Mann-Whitney U test.
Main Results:
- Arthritis was present in 7% of bacterial meningitis episodes (48/696).
- Meningococcal meningitis had the highest arthritis incidence (12%).
- Of those with arthritis, 48% underwent joint fluid aspiration, with 26% yielding positive bacterial cultures. Mortality was 8%, and 23% experienced residual joint symptoms.
Conclusions:
- Arthritis is a common complication of community-acquired bacterial meningitis.
- Outcomes vary by causative agent; meningococcal arthritis is typically immune-mediated and less deforming than staphylococcal arthritis.
- Consideration of additional therapies and mandatory prolonged antibiotic treatment for infectious arthritis are recommended.
