Overview

Differential Diagnosis

Differentiating gonococcal arthritis from non-gonococcal arthritis
Characterestic Gonococcal arthritis Non gonococcal arthritis
Patient profile
  • Mostly sexually active young adult
  • Female > male
  • Patient with history of rheumatoid arthritis or other systemic arthritis
  • Immunocompromised patient
  • Common in extremes of age such as in newborn or elderly
Initial presentation
  • Migratory polyarthralgia is common
  • Tenosynovitis in majority of patients
  • Dermatitis in majority of patients
  • Single hot, swollen and painful joint
  • Polyarthralgia is very rare
  • Tenosynovitis and dermatitis are very rare.
Polyarticular involvement
  • Common (~40–70% of patients)
  • Usually involves 2-3 joints
  • Rare (~10–20% of patients).
  • Mostly monoarticular involvement (>85%)
Recovery of bacteria
  • Positive blood culture <10%
  • Positive synovial fluid culture <50%
  • Positive blood culture 50%
  • Positive synovial fluid culture >90%
Response to antibiotics
  • Within a few days outcome excellent
  • Takes weeks
  • Joint drainage must be adequate
  • Outcome often poor
