Primary meningococcal polyarthritis
Abstract:
We report a case of primary meningococcal polyarthritis simulating bacteraemic gonococcal infection. The clinical similarity between extragenital gonococcal and meningococcal infections is well illustrated. If the clinical features of meningococcal and gonococcal infections are usually different, they may sometimes be indistinguishable. Both gonococcal pharyngitis and meningococcal urethritis have been recorded. The onset of acute polyarthritis, fever and skin lesions is typical of gonococcal infection but these clinical features may also indicate infection due to Neisseria meningitidis. In the case we report, the correct diagnosis of meningococcal arthritis was established only after N. meningitidis group C had been identified in synovial fluid from the knee.
Insights
Primary meningococcal polyarthritis can mimic gonococcal infections, presenting similar symptoms like joint pain, fever, and skin lesions. Definitive diagnosis requires identifying Neisseria meningitidis in synovial fluid.
Area of Science:
- Infectious Diseases
- Rheumatology
- Microbiology
Background:
- Extragenital infections caused by Neisseria gonorrhoeae and Neisseria meningitidis can present with overlapping clinical features.
- Distinguishing between meningococcal and gonococcal infections can be challenging due to similar symptoms such as polyarthritis, fever, and skin manifestations.
