I. See Also

II. Pathophysiology

  1. Rheumatoid disease in children

III. Types

  1. Pauciarticular (4 or fewer joints involved)
    1. Age at presentation <8 years
    2. Involves large joints and is typically asymmetric
    3. Boys may develop sacroiliitis
    4. Iridocyclitis may be present
  2. Polyarticular (>4 joints involved)
    1. Age at presentation 1-6 or 11-16 years
    2. Involves small joints with symmetric involvement
    3. Rheumatoid Factor may be positive
      1. Positive Rheumatoid Factor confers similar presentation to Rheumatoid Arthritis in adults
  3. Systemic (Still's Disease)
    1. High daily Relapsing Fever >39 degrees persists over 2 weeks (most distinguishes this type from others)
    2. Polyarticular involvement with >4 joints involved
    3. Hepatomegaly and Splenomegaly
    4. Lymphadenopathy
    5. Pleural Effusion or Pericardial Effusion may be present
    6. Recurrent evanescent rash
      1. Faint salmon colored rash over trunk, palms and soles

IV. Symptoms

  1. Pediatric Limp (most common presentation)
  2. Pain is minimal compared to inflammatory signs
    1. Increasing pain has Negative Predictive Value for RA

V. Signs

  1. Similar to adult form of Rheumatoid Arthritis
    1. Joint Swelling with warmth (not red and hot)
  2. Differences from Adult Rheumatoid Arthritis
    1. Higher fever
    2. Rheumatoid Nodules are rare
    3. Pericarditis and valvulitis are more common
    4. Lymphadenopathy and hepatosplenomegaly are common
    5. Arthritis interferes with bone growth
      1. Example: underdeveloped Mandible
    6. Uveitis most common juvenile RA eye disorder
      1. Occurs in up to 50% of pauciarticular juvenile RA
        1. Highest risk if ANA positive and recent onset
      2. Asymptomatic in up to 80% of cases
      3. Delayed diagnosis risks Cataracts, Glaucoma, blind
      4. Ophthalmology should follow all with juvenile RA

VII. Labs (often non-diagnostic)

  1. Rheumatoid Factor
    1. Variably positive, often normal
  2. Antinuclear Antibody
    1. May be associated with Uveitis (see above)
  3. Erythrocyte Sedimentation Rate (ESR)
    1. High ESR may suggest other diagnoses (e.g. infection)
  4. Complete Blood Count
    1. Abnormal in systemic presentation

VIII. Diagnosis (diagnosis of exclusion)

  1. Chronic Arthritis of one or more joints for 6 weeks
  2. Other diagnoses excluded

IX. Management

  1. NSAIDs
  2. TNF agents
