TY - CHAP M1 - Book, Section TI - Gout A1 - Bottenberg, Michelle M. A2 - Sutton, S. Scott PY - 2019 T2 - McGraw-Hill's NAPLEX® Review Guide, 3e AB - Gout is characterized by acute and recurrent arthritis mediated by the formation of monosodium uric acid (MSU) crystals within the joints and surrounding tissues. This results in pain, erythema, and inflammation. Elevated serum uric acid (SUA) concentrations are a result of a defect in purine metabolism, a decrease in uric acid excretion, increased nucleic acid turnover, or increased purine production. Uric acid is a metabolic by-product of purine compounds derived from dietary sources or the breakdown of DNA within the body’s cells. Uric acid is excreted by the kidneys and can accumulate if production exceeds excretion. A majority of patients with gout accumulate excessive uric acid due to underexcretion of the compound. Regardless of the cause, excessive intake of high purine foods contributes to hyperuricemia and gout exacerbations (Table 48-1).
