Rheumatoid Arthritis Diagnostic Tests

• Lab tests

• · No specific tests
• ESR: Usually elevated
• C-reactive protein: Unspecific, direct measure of impact of IL-6 on liver cells
• Rheumatoid factor (RF): >1:80 in 70–80% of patients with RA (most commonly IgM Ab)
• · Rheumatoid factor positive
• · Normochromic normocytic anaemia
• · Increased ESR
• · Increased C-reactive protein

• Imaging –

• X-ray
  • Radiographic abnormalities are very useful in the diagnosis and treatment.
  • Periarticular osteopenia is the earliest change.
  • Typical deformity seen in the joints affected.
• CT Scan, MRI
•  mTc biphosphonate bone scan

Rheumatoid Arthritis Differential Diagnosis

• Vasculitis: Behçet syndrome
• Seronegative polyarthritis
• Erosive osteoarthritis
• Chronic infections: Lyme disease
• Other systemic connective tissue diseases:
• Sjögren syndrome, systemic lupus erythematosus, systemic sclerosis, adult Still disease, mixed connective tissue disease
• Psoriatic arthritis
• Viral-induced arthritis: Parvovirus B19, hepatitis C (with cryoglobulinemia)
• Occult malignancy

Rheumatoid Arthritis Treatment

• Relief of pain
• Reduce inflammation Restore function
• Treat systemic features Protection of joints.
• Start DMARDs within 2 months of diagnosis if patient has ongoing active disease despite appropriate dose of aspirin or other NSAIDs.
• Precautions: Offer proton pump inhibitors (PPIs) for chronic NSAID therapy; avoid NSAID combination.
• Relief of Pain
  • · NSAIDs (Ibuprofen, aceclofenac, nimuselide).
  • · COX-I! inhibitors (Rofecoxib, valdecoxib – not approved by FDA).
• Reduce inflammation
  • GlucocorticoidsSome Facts about Glucocorticoid & Major side effects. Read more ... ». Intraarticular glucocorticoids.
• Disease modifying Antirheumatic drugs (DMARDs)
  • Methotrexate, Gold compounds, Antimalarials, Sulfasalazine.
  • Methotrexate (MTX) (Rheumatrex): 7.5–25 mg per week PO
• Immunosuppressive/ cytotoxic drugs Omega-3 fatty acids
  • Leflunomide (Arava): Dose: 10–20 mg/d. Modifies T-cell function to decrease autoimmune activity,
• Surgery
  • Reconstructive, arthroplasties, joint replacement, synovectomy.
