Evaluation of the Enzyme-Linked Immunoelectrotransfer Blot Assay for Diagnosis of Neurocysticercosis in Children

Neurocysticercosis is a common problem in developing countries, and it causes neurologic disorders in children. Immunodiagnosis with Taenia solium glycoproteins as an antigen has been validated in adults but not in children. The aim of this work was to evaluate a Taenia solium glycoproteins-based en...

Description
Summary:Neurocysticercosis is a common problem in developing countries, and it causes neurologic disorders in children. Immunodiagnosis with Taenia solium glycoproteins as an antigen has been validated in adults but not in children. The aim of this work was to evaluate a Taenia solium glycoproteins-based enzyme-linked immunoelectrotransfer blot assay in children with neurocysticercosis. Twenty-five confirmed cases of neurocysticercosis and 50 healthy children from the same community were included. The test had a sensitivity of 72% and a specificity of 96%. Sensitivity was higher (100%) in cases with multiple cysts and in multiple sites. Sensitivity was higher when cysts were in parenchyma (86%) than when they were in the subarachnoid space. The most frequently recognized proteins were 24, 39 to 42, and 50 kDa. Diagnosis was more efficient in serum than in cerebrospinal fluid. Western blot is a reliable method for serologic diagnosis of neurocysticercosis in children. Multiple cysts and infections in multiple sites elicited a stronger immune response.
