FIRST PARAGRAPH: Gout is caused by disordered purine metabolism resulting in hyperuricemia. Symptoms are related to the precipitation of monosodium urate (uric acid) crystals, typically in joint spaces or soft tissue. Primary gout is caused by an increase in uric acid production, while secondary gout is caused by either a decrease in urinary uric acid excretion or an overproduction of purine secondary to increased cell turnover (e.g., tumor lysis). Predisposing clinical factors include older age (fifth and older decade), male sex, obesity, heavy alcohol ingestion, a purine-rich diet, certain medications (e.g., thiazide diuretics), and genetic factors.
