Seronegative synovitis syndrome, characterized by joint inflammation without rheumatoid factor, presented acutely in three patients. The condition resolved completely within 18 months, showing no long-term damage or relapse.

Area of Science:

  • Rheumatology
  • Clinical Medicine
  • Immunology

Background:

  • Seronegative synovitis syndrome is a rare condition characterized by joint inflammation in the absence of specific autoantibodies.
  • Understanding its clinical presentation and prognosis is crucial for accurate diagnosis and management.

Observation:

  • Three patients (two elderly women, one man) presented with acute, symmetrical polysynovitis affecting appendicular joints and flexor digitorum tendons.
  • Pitting edema of the hands and feet was a notable associated symptom.
  • All patients tested negative for rheumatoid factor, and no erosions were observed radiologically.

Findings:

  • The syndrome exhibited a benign clinical course in all reported cases.
  • Complete resolution of synovitis occurred within 2 to 18 months post-onset.

  • Long-term follow-up (22-34 months) revealed no deformities, erosions, or relapses.

    • Implications:

    • This case series highlights the favorable prognosis of seronegative synovitis syndrome.
    • It underscores the importance of considering this diagnosis in patients with acute synovitis and negative rheumatoid factor.
    • Further research may elucidate the underlying pathophysiology and identify specific biomarkers.
