Case Report: A 37-year-old man ingested in a suicide attempt 300 mL of a di
quat solution (equivalent to 60 g diquat ion). The initial diquat serum con
centration was 64 mu g/mL 4 hours after poisoning. The clinical course was
characterized by a progressive anuria and by neurological disorders (coma a
nd seizures). The patient died 26 hours after poisoning from refractory car
diocirculatory collapse. Extracorporeal techniques removed 1.09 g of diquat
which could be considered as significant in regard to the total amount tha
t was likely absorbed, but they did not influence the clinical outcome. The
re was marked renal tubular damage at autopsy and the highest diquat tissue
concentration was found in the kidneys.
