[Acute organophosphorus pesticide poisoning and cholinesterases activities].
Suicides attempts with an organophosphate pesticide still occur in Brittany, an agricultural French area. The acute poisoning due to this nerve agent, responsible for the inhibition of the cholinesterases enzymes, is severe and can be fatal. The diagnosis is based on the decrease of cholinesterases activity, an assay which has been performed because of the patient context. The measurement of butyrylcholinesterases activity in emergency guarantees an appropriate and rapid management of the patient in order to rapidly regenerate cholinesterases. Even if the decrease level of butyrylcholinesterases activity does not give a significant prognostic value, its follow-up with time indicates the efficacy of the treatment and the gradual remission. In routine the measurement of acetylcholinesterase activity is more useful for the biological follow-up of subjects exposed to organophosphate phytosanitary compounds.
