Introduction. Diquat is an herbicide that can lead to rapid multiorgan system failure upon toxic ingestion. Although Diquat shares a similar chemical structure with paraquat, diquat is still readily available to the general population, and in contrast to paraquat, it is not regulated. We present a case of an intentional diquat poisoning which emphasizes the necessity of the early recognition due to atypical symptoms within the first 24 hours and certainly enhanced regulatory restrictions on this very toxic compound. Case. A 60-year-old male with a history of severe depression presented to the emergency department after intentional ingestion of a commercial herbicide containing diquat dibromide 2.30%. The earliest manifestations of this acute diquat intoxication comprised a glomerulonephritis and proximal tubular dysfunction. Progressive multiorgan system failure then developed with a significant delay (24-38 hours) including acute renal, liver failure, and then respiratory failure with refractory hypoxemia. Despite maximal supportive care, the end organ failure was lethal. Discussion. Diquat intoxication should be suspected in patient presenting an acute glomerulonephritis with coma. Diquat should undergo the same regulatory restrictions as paraquat-containing compounds.
