Arthritis associated with salmonella infection
Clinical Rheumatology
|December 1, 1982
Summary
Salmonella infection can cause distinct types of arthritis, including infectious or reactive forms. A chronic destructive reactive arthritis may be immune-complex mediated, even with negative Widal tests.
Area of Science:
- Rheumatology
- Infectious Diseases
- Immunology
Background:
- Salmonella infections are known to be associated with reactive arthritis.
- The Widal test is commonly used to diagnose Salmonella infections, but its sensitivity for detecting associated arthritis can be limited.
Observation:
- This study reports six cases of arthritis linked to Salmonella infection.
- A specific case of chronic destructive "reactive" oligoarthritis is detailed, exhibiting similarities to experimental Salmonella-associated arthritis in rats.
Findings:
- Salmonella infection can lead to two primary forms of arthritis: monoarticular infectious arthritis and subacute reactive oligoarthritis.
- Negative Widal test results do not rule out Salmonella-associated arthritis.
- The chronic destructive reactive arthritis observed may be an immune complex-mediated disease stemming from chronic infection.
Implications:
- Highlights the importance of considering Salmonella as a potential cause of reactive arthritis, irrespective of Widal test results.
- Suggests a potential immune-complex mechanism in chronic Salmonella-associated arthritis.
- Informs clinical diagnosis and management of patients presenting with arthritis potentially linked to Salmonella.
