NCT00755560

Brief Summary

The purpose of this study is to evaluate effectiveness of albendazole in the treatment of the asymptomatic infection with the parasite Toxocara in children. Treatment response is defined as a reduction in the number of eosinophils in blood. The study drug will be compared to placebo and randomly assigned in a double blind manner. Follow up will be prospective. 50 children (25 per group) will be enrolled in the study.
