Original title Intoxications par le fer [in French]

Abstract Most acute intoxications caused by iron are the result of ferrous salt ingestion, either accidentally in children or more rarely in suicidal attempts among adults. The main toxic mechanism of iron is related to its capacity to induce the formation of free radicals, followed by lipid peroxidation. Classically, five clinical phases have been identified: gastrointestinal toxicity; transitory relative stability; systemic toxicity with shock, metabolic acidosis and coma; hepatotoxicity with coagulopathy; gastrointestinal scarring. Therapy includes supportive care, whole bowel irrigation and the use of deferoxamine, a specific iron chelator. Activated charcoal is ineffective. Chronic exposure to iron occurs primarily in occupational settings and causes pneumoconiosis following the inhalation of dust and iron oxides. Ocular siderosis is a chronic disease that may lead to a vision loss. It occurs when a particle containing iron penetrates in the eye.
