Acute onset of severe joint pain.
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 (NSAIDs), colchicine, or corticosteroids are used to treat acute disease.
Allopurinol, febuxostat, probenecid, lesinurad, or sulfinpyrazone may be used as uric acid-lowering drugs 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.
