Abstract

Gout is caused by monosodium urate crystal deposition in joints and tissues. Risk factors include male sex; obesity; hypertension; alcohol intake; diuretic use; a diet rich in meat and seafood; chronic kidney disease; a diet heavy in fructose-rich food and beverages; being a member of certain ethnic groups, including Taiwanese, Pacific Islander, and New Zealand Maori; and living in high-income countries. Gout is characterized by swelling, pain, or tenderness in a peripheral joint or bursa, including the development of a tophus. Diagnosis of gout can be made using several validated clinical prediction rules. Arthrocentesis should be performed when suspicion for an underlying septic joint is present; synovial fluid or tophus analysis should be performed if the diagnosis is uncertain. Colchicine, nonsteroidal anti-inflammatory drugs, and corticosteroids relieve pain in adults with acute gout episodes. Indications for long-term urate-lowering therapy include chronic kidney disease, two or more flare-ups per year, urolithiasis, the presence of tophus, chronic gouty arthritis, and joint damage. Allopurinol and febuxostat are used to prevent flare-ups, although febuxostat is associated with an increase in all-cause and cardiovascular mortality and is therefore not routinely recommended.
