Neurocysticercosis in children: clinical therapy in a randomized, double-blind, placebo-controlled trial in newly diagnosed cases

The clinical findings of neurocysticercosis, diagnosed primarily on the basis of computed tomography (CT), and response to albendazole therapy in a randomized, double-blind, placebo-controlled trial were studied in 72 newly diagnosed children aged 1.5-12 years admitted to hospital in New Delhi, India, during March to July 2000. The lesions by initial CT were mostly single with perilesional oedema, and were located in the parietal lobes. The most common clinical finding was partial seizure (79.2%). The outcome of the albendazole trial was assessed through changes in CT lesions and status of seizure after 6 months of follow-up; about 55% of the lesions had disappeared and about 80% of the children were seizure-free. The frequency of healing of CT lesions in the albendazole-treated group and placebo group was 54.2% and 55.2%, respectively, and the frequency of a seizure-free state in the albendazole-treated group and placebo group was 87.5% and 77.5%, respectively; the differences were not statistically significant. Changes in lesions by CT and the recurrence of seizures after 6 months of follow-up were not related to the number of lesions by initial CT and albendazole was not beneficial in neurocysticercosis in children with ring-enhancing lesions in CT.
