Gout is characterised by acute onset of severe joint pain, with swelling, effusion, warmth, erythema, and or tenderness of the involved joint(s).
Arthrocentesis with synovial fluid analysis shows strongly negative birefringent needle-shaped crystals under polarised light.
Non-steroidal anti-inflammatory drugs, colchicine, corticosteroids, or interleukin-1 inhibitors are used to treat acute disease.
Uric acid-lowering drugs (e.g., allopurinol, febuxostat, probenecid, or sulfinpyrazone) may be used when long-term prevention of crystal deposition is indicated.
Complications include joint destruction, kidney disease, and urolithiasis.
Gout is a syndrome characterised by: hyperuricaemia and deposition of urate crystals causing attacks of acute inflammatory arthritis; tophi around the joints and possible joint destruction; renal glomerular, tubular, and interstitial disease; and uric acid urolithiasis.
The disease most commonly affects the first toe (podagra), foot, ankle, knee, fingers, wrist, and elbow; however, it can affect any joint.
