[Physiopathological bases for a rational therapy of gout].

Rational therapy of gout must be correlated with the two basic aetiopathogenetic factors, i.e. metabolic error and the inflammatory dysreactive moment. Due to its different action mechanism, the former is responsible for the typing of adult primary hyperuricaemia: a) hyperincorporating and hyperescretory forms; b) normo-incorporating and relatively or absolutely hypoexcretory forms; c) hyperincorporating and hyposcretory forms. It would be a mistake to treat the condition chemically without knowing the physiopathology of the metabolic error. On the basis of a preliminary typing assessment, rational chemical correction of the metabolic error in gout cases can be achieved with drugs that block the enhanced endogenous synthesis of uric acid (allopurinol, etc.) or correct the metabolite renal excretion defect. Therapy of the dysreactive-inflammatory component should involve non-steroid anti-inflammatory drugs. The disadvantages of using cortisones in gout treatment are stressed.
