[Favorable evolution of severe paraquat poisoning. Treatment with gastric lavage, activated charcoal, cyclophosphamide + corticoids, and conventional daily hemodialysis: case study at the Franck Joly Hospital Center in french Guiana].

We report the observations of two patients, having voluntarily ingested lethal doses of paraquat with suicidal intent, with an unfavorable prognostic score. The treatment consisted of gastric lavage, administration of activated charcoal, n-acetylcysteine and cyclophosphamide + methylprednisolone + dexamethasone. The installation of acute renal failure motivated the initiation of daily conventional hemodialysis (HD) over 10 to 14 days, with a favorable evolution. The following complications were recorded: anemia, bacteremia and deep vein thrombosis. These observations raise three questions in the treatment of paraquat intoxication: the effectiveness of HD, the interest of its association with the above therapies in the prevention of pulmonary fibrosis, and the need for infectious prevention and thromboembolism. Furthermore, the absence of a paraquatemia assay cannot constitute a limitation for management, and hemoperfusion on an inaccessible charcoal column can be replaced by an HD usually available.
