Gout: current concepts and treatment

Gout is a disorder of purine metabolism, of varied etiology, associated with an increase in serum uric acid and a recurrent arthritis. The defect may be either metabolic or renal, or either unknown etiology or associated with other disease states. The acute arthritis has been shown to be due to a crystal (sodium urate) synovitis. The many chronic complications, arthritic, renal and vascular, necessitate a vigorous and longterm treatment program. With the advent of the xanthine oxidase inhibiter Allopurinol, excellent control of gout and its complications can be achieved in a large number of patients, with good control in the remainder.
