Abstract |
The aim of this study was to evaluate the efficacy of meso-2,3-dimercaptosuccinic acid ( DMSA) treatment in workers with increased lead absorption and no overt symptoms of lead poisoning. Seven occupationally lead exposed male workers with blood lead concentrations (PbB) exceeding 50 micrograms/100 ml and a positive calcium disodium ethylenediaminetetraacetate ( EDTA) lead mobilization test were treated with DMSA for 19 days. Individual doses were 700 mg DMSA, three times a day from day one to five, and twice a day from day six to 19. The treatment intensified urinary lead excretion, most rapidly during the first five days. The increased elimination was followed by a decline of mean PbB to 15% of the pretreatment values. However, 15 days after the treatment, the PbB concentrations rebounded, yet kept below the baseline values and did not exceed 40 micrograms/100 ml. After repeated EDTA lead mobilization test, urine lead was 23-68% of that before DMSA treatment. It can be concluded that DMSA can effectively reduce chelatable lead in occupationally exposed workers.
