[Treatment of lead poisoning by drinking water using hemofiltration and chelationin a hemodialysed anuric patient].

Lead intoxication was diagnosed in April 1984 in an anuric woman of 65 years of age, whose hemodialysis had begun 9 years previously. Lead poisoning was completely cured by repeated hemofiltration with calcium EDTA. 28.2 mg of lead were extracted during 26 hemofiltration sessions. After the twentieth session, the rate of extracted lead was 500 micrograms per session and the rate of delta-aminolevulinic acid dehydrase was normalized. This exceptional observation allowed a nearly experimental study of the kinetics and metabolism of Ca EDTA chelated lead.
