We report the case of a 77-year-old man with Parkinson’s disease (PD) who experimented for the first time gout crisis after initiation of levodopa. Levodopa was withdrawn, colchicine and allopurinol were initiated to treat the gout crisis. Because of PD progression, levodopa was reintroduced, and the patient presented relapse of gout flare. To further explore the association between gout and levodopa, we extracted and synthetized all Individual Case Safety Reports of gout associated with levodopa in the World Health Organization pharmacovigilance database, VigiBase®, up to April 2021. 43 cases of gout were reported in VigiBase® with drugs from N04BA ATC class. Levodopa was suspected in fifteen cases among which improvement was noticed in six cases (two after levodopa withdrawal, two despite treatment continuation, and two cases lacking details about action taken with levodopa); three cases did not recover; in the remaining six cases, evolution was not known. “Hyperuricemia” was not mentioned in the Summary of Product Characteristics of medicine containing levodopa; however, “abnormality biologics test with uric acid” was mentioned. Despite few cases of recovery after reduced doses of levodopa, the above described case of positive reintroduction was an argument in favor of the role of levodopa in gout flare. This study highlights a potential association between levodopa and gout through an analysis of the cases reported in the WHO pharmacovigilance database.
