Differential Diagnosis: Gout vs. Other Conditions

When diagnosing gout, it’s crucial to differentiate it from other conditions that can present with similar symptoms, such as joint pain, inflammation, and swelling. Here’s a summary of the differential diagnosis:

1. Pseudogout (Calcium Pyrophosphate Deposition Disease – CPPD)

• Similarities: Both gout and pseudogout cause acute joint inflammation and swelling.
• Differences:
  • Crystals: Pseudogout involves calcium pyrophosphate crystals, which are rhomboid-shaped and have positive birefringence under polarized light. Gout involves monosodium urate crystals (needle-shaped, negative birefringence).
  • Joints Affected: Pseudogout commonly affects larger joints like the knees, whereas gout frequently targets the big toe (first metatarsophalangeal joint).

2. Septic Arthritis

• Similarities: Both can present with acute joint swelling, pain, warmth, and erythema.
• Differences:
  • Fever: Septic arthritis often presents with systemic symptoms like fever, while gout typically does not.
  • Synovial Fluid: In septic arthritis, synovial fluid analysis shows very high white blood cell count (>50,000 cells/mm³) and bacteria may be present on Gram stain or culture.
  • Onset: Septic arthritis has a rapid onset and is often monoarticular, just like gout.

3. Rheumatoid Arthritis (RA)

• Similarities: Chronic joint pain and swelling, with possible morning stiffness.
• Differences:
  • Joints: RA typically involves small joints of the hands and wrists bilaterally, while gout frequently affects one joint, especially in the lower extremities.
  • Crystals: No crystals are found in RA synovial fluid analysis. Inflammatory markers like rheumatoid factor (RF) or anti-CCP antibodies are usually positive in RA.
  • Symmetry: RA affects joints symmetrically, while gout often affects a single joint asymmetrically.

4. Osteoarthritis (OA)

• Similarities: Both can cause joint pain, swelling, and stiffness.
• Differences:
  • Onset: OA typically has a gradual onset and is related to wear-and-tear, while gout has a sudden, acute onset.
  • Joints: OA affects weight-bearing joints (hips, knees), whereas gout is common in the toe.
  • Synovial Fluid: In OA, synovial fluid has low WBC count and no crystals.

5. Reactive Arthritis

• Similarities: Both can cause acute joint inflammation.
• Differences:
  • History: Reactive arthritis typically follows an infection (e.g., gastrointestinal or genitourinary), while gout is linked to hyperuricemia.
  • Joints: Reactive arthritis often affects larger joints and is associated with additional symptoms like eye inflammation (conjunctivitis) or urethritis.

6. Trauma

• Similarities: Both trauma and gout can cause joint pain, swelling, and warmth.
• Differences:
  • History of Injury: Trauma often follows a clear injury or overuse, while gout may occur spontaneously or after a trigger like dietary intake.
  • Imaging: X-rays can show signs of injury in trauma but may show gouty tophi or urate deposits in chronic gout.

7. Psoriatic Arthritis

• Similarities: Both conditions can cause joint pain and swelling.
• Differences:
  • Skin Involvement: Psoriatic arthritis is associated with psoriasis (skin lesions), while gout is not.
  • Pattern of Joint Involvement: Psoriatic arthritis tends to affect the joints asymmetrically and can involve the distal interphalangeal joints.

Key Diagnostic Tools:

• Synovial Fluid Analysis: Essential for identifying crystals in gout and pseudogout, ruling out infection, and differentiating from other inflammatory arthritis.
• Serum Uric Acid: Elevated in gout, but not diagnostic on its own as some patients with gout have normal uric acid levels during attacks.
• Imaging: X-rays may show erosions or tophi in chronic gout, but are less useful in acute diagnosis.

By considering these factors, a clinician can distinguish gout from other potential causes of joint pain and inflammation.
