Pasteurella multocida polyarticular septic arthritis
The Journal of Rheumatology
|April 1, 1987
Abstract:
Pasteurella multocida is an unusual cause of septic arthritis with most patients having underlying joint damage or altered host defenses. We report 2 cases of polyarticular sepsis with this bacteria. Predisposing factors in our patients included alcoholic cirrhosis, end stage renal disease and metastatic malignancy. Heightened awareness of this organism's involvement in polyarticular septic arthritis in the immunocompromised patient is emphasized.
Insights
Pasteurella multocida rarely causes septic arthritis, typically in immunocompromised individuals with joint issues. This study highlights two such cases, emphasizing the need for awareness in at-risk patients.
Area of Science:
- Infectious Diseases
- Rheumatology
- Microbiology
Background:
- Septic arthritis is commonly caused by Staphylococcus aureus and Streptococcus species.
- Pasteurella multocida is an uncommon pathogen, usually associated with animal bites or scratches.
- Risk factors for atypical septic arthritis include joint damage and compromised immune systems.
Observation:
- Two cases of polyarticular septic arthritis caused by Pasteurella multocida are presented.
- Patients had significant comorbidities, including alcoholic cirrhosis, end-stage renal disease, and metastatic malignancy.
- These predisposing factors likely contributed to the unusual presentation.
Findings:
- Pasteurella multocida can cause severe, widespread joint infections.
- Immunocompromised status and underlying joint pathology are critical risk factors.
- Prompt identification and treatment are essential for favorable outcomes.
Implications:
- Clinicians should consider Pasteurella multocida in the differential diagnosis of septic arthritis, especially in immunocompromised patients.
- Increased awareness may lead to earlier diagnosis and improved management of these rare infections.
- Further research into the pathogenesis and treatment of Pasteurella multocida septic arthritis is warranted.
