Gout induced by L-dopa and decarboxylase inhibitors

Abstract
Two cases of clinical gout are reported in parkinsonian patients receiving L-dopa in combination with a decarboxylase inhibitor. Blockade of decarboxylation leads to major changes in the pattern of L-dopa metabolites. It is suggested that hyperuricaemia may result from accumulation of L-dopa itself or a transaminated product.
