Differential
- Rheumatoid Arthritis:
- Infection:
- w/ rapid destruction of gouty joint (by intraarticular infection), crystalline deposits may be released into synovial fluid, leading to confusion;
- note that indomethacin can quell the clinical symptoms of early septic arthritis (just as it will w/ gout), and therefore, NSAIDs should not be used to differentiate between gout and infection;
- Pseudogout
- Rheumatic fever
- Hyperparathyroidism
- Bone Tumor
- Diabetic Ischemia
Secondary Gout
- Myeloroliferative disorders (polycythemia, AGL, CGL)
- Multiple Myeloma;
- Sickle Cell;
