Acute iron poisoning. Rescue with macromolecular chelators.

Acute iron poisoning. Rescue with macromolecular chelators.

Acute iron intoxication is a frequent, sometimes life-threatening, form of poisoning. Present therapy, in severe cases, includes oral and intravenous administration of the potent iron chelator, deferoxamine. Unfortunately, high dose intravenous deferoxamine causes acute hypotension additive with that engendered by the iron poisoning itself. To obviate this problem, we have covalently attached d...

Ceruloplasmin: Macromolecular Assemblies with Iron-Containing Acute Phase Proteins

Copper-containing ferroxidase ceruloplasmin (Cp) forms binary and ternary complexes with cationic proteins lactoferrin (Lf) and myeloperoxidase (Mpo) during inflammation. We present an X-ray crystal structure of a 2Cp-Mpo complex at 4.7 Å resolution. This structure allows one to identify major protein-protein interaction areas and provides an explanation for a competitive inhibition of Mpo by C...

[Acute iron poisoning. A case report].

The ingestion of iron-containing products is a potential toxicological emergency. It is a leading cause of pediatric unintentional ingestion fatalities because some iron-containing compounds are readily available (vitamin mixtures, iron pills). Among adults, it has been described as accidental overdoses (mainly in pregnancy) and as suicidal attempts. We report a 42 years old woman, admitted due...
