- Title
Lightening the Lead Load in Children.

- Abstract
More than 4 percent of preschool-aged children in the United States have blood lead levels above 10 Mu g per dL (0.50 Mu mol per L), and these levels have been associated with a decline in IQ. The Centers for Disease Control and Prevention advocates the use of a screening questionnaire to identify lead exposure or toxicity in all children. Primary prevention through the removal of lead from gasoline and paint has led to a reduction of blood lead levels in children. Secondary prevention through paint hazard remediation is effective in homes that have a high lead burden. Children with lead levels of 45 to 69 Mu g per dL (2.15 to 3.35 Mu mol per L) should receive chelation therapy using succimer (DMSA) or edetate calcium disodium (CaNa2EDTA). Use of both CaNa2EDTA and dimercaprol (BAL in oil) is indicated in children with blood lead levels higher than 70 Mu g per dL (3.40 Mu mol per L). Current treatment recommendations are based on the reduction of blood lead levels, which may not represent a significant overall reduction of the lead burden. Clinical trials of existing agents are needed to determine patient-oriented outcomes, such as the effect on IQ.
