Gout is an inflammatory arthritis that occurs in response to the deposition of MSU crystals, the end product of human purine metabolism, in joints, soft tissues, and bones Abstract. More than% of the population in affluent countries has hyperuricemia (21% of males but only 3% of premenopausal females), however, only about % develop gout The genetic, metabolic, and environmental causes of hyperurice-mia and the physicochemical processes that lead to uric acid crystallization have been reviewed in PATHOGENESIS OF GOUT. In the human body, urate is constantly near its limit of solubility, in a flux balance between production and elimination. URIC ACID PRODUCTION.
