Patient's question:
Female, 1 year and 1 month, checked today for zinc and calcium deficiency, but high lead content. The doctor recommended lead removal. How can lead be eliminated? Currently, the diet consists of breast milk and complementary foods.Doctor's answer:
Hello: The main treatment for chronic lead poisoning is chelation therapy. The effectiveness of chelating agents in promoting lead excretion is as follows: CaNa3DTPA (Calcium Disodium Ethylenediaminetetraacetic Acid) > CaNa2EDTA (Calcium Disodium Edetate) > ZnNa3DTPA (Zinc Disodium Ethylenediaminetetraacetic Acid) > Na2DMS (Sodium Dimercapto succinate) > DMSA (Dimercaptosuccinic Acid) > 811 (Chelating Carboxyphenol). The specific usage is as follows:CaNa2EDTA or CaNa3DTPA
