Gout and vitamin A intoxication: is there a connection?
Several lines of indirect evidence implicate vitamin A intoxication, associated mainly with impaired renal function, in the etiopathogenesis of gouty arthritis. The enzyme xanthine oxidase is involved not only in the conversion of xanthine to uric acid but also in that of retinol to its more toxic metabolite, retinoic acid. Retinoic acid should therefore be present in high concentration in hyperuricemic states.
