TLDR
EITB was more sensitive and specific than ELISA for epidemiological studies of neurocysticercosis and was strengthened by the higher rate of abnormal findings compatible with neurocyticercosis on computed tomography of the brain among individuals with a history of convulsions.Abstract:Â
We compared a plate enzyme-linked immunosorbent assay (ELISA) with an immunoblot--or enzyme-linked immunoelectrotransfer blot--assay (EITB) for the identification of cases of human neurocysticercosis due to Taenia solium and of risk factors for this disease in two Mexican villages. Findings related to age- and sex-specific seroprevalence, risk factors for transmission, and associated morbidity differed significantly according to the assay used. Rates of EITB positivity were significantly higher among persons with a history of convulsions than among those without such a history (29% vs 8%; P < .05); in contrast, ELISA results were negative for all persons with a history of convulsions. The association of seizures with neurocysticercosis in this population was strengthened by the higher rate of abnormal findings compatible with neurocysticercosis on computed tomography of the brain among individuals with a history of convulsions than among those without such a history (70% vs 14%; P < .001). In summary, EITB was more sensitive and specific than ELISA for epidemiological studies of neurocysticercosis.read more

Taenia solium cysticercosis
Hector H. Garcia,Armando E. Gonzalez,Armando E. Gonzalez,Carlton A. Evans,Robert H. Gilman,Robert H. Gilman +5 more
TL;DR: Clinical manifestations vary because of the variable number, size, and location of the cysts and the immune response of the host.
Journal ArticleDOI
Taenia solium cysticercosis.
TL;DR: The larval stage of the pork tapeworm infects the human nervous system, causing neurocysticercosis, one of the main causes of epileptic seizures in many less developed countries and also increasingly seen in more developed countries because of immigration from endemic areas.

Neurocysticercosis: Updates on Epidemiology, Pathogenesis, Diagnosis, and Management
TL;DR: Patients with neurocysticercosis should be treated with corticosteroids, antiparasitic drugs, and shunting if hydrocephalus is present, and the pathogenesis and clinical manifestations vary with the site of infection and accompanying host response.
Journal ArticleDOI
Neurocysticercosis: A major cause of neurological disease worldwide
TL;DR: The increased ease of international travel, the increasing numbers of immigrants from developing countries, and the widespread use of improved diagnostic techniques have led to widespread recognition of neurocysticercosis as a common infection not only in developing countries but also in the United States.
Journal ArticleDOI
Cysticercosis and epilepsy: a critical review.
TL;DR: There is a discrepancy between the results of serologic assays and neuroimaging studies: >50% of those individuals with NC diagnosed by computed tomography (CT) scan test EITB negative, and most seropositive individuals are asymptomatic.

Statistical methods for rates and proportions
TL;DR: In this paper, the basic theory of Maximum Likelihood Estimation (MLE) is used to detect a difference between two different proportions of a given proportion in a single proportion.

An Enzyme-Linked Immunoelectrotransfer Blot Assay and Glycoprotein Antigens for Diagnosing Human Cysticercosis (Taenia solium)
TL;DR: An enzyme-linked immunoelectrotransfer blot (EITB) assay was developed for immunodiagnosing human cysticercosis and identified seven major glycoprotein bands that are commonly recognized by virtually all serum and/or CSF samples from patients with confirmed cysticERCosis.

TL;DR: It is confirmed that the EITB assay for cysticercosis antibodies is highly sensitive in patients with multiple, enhancing intracranial lesions but is less sensitive in Patients with single lesions and in those with calcified lesions.

TL;DR: The results of this study have identified community behavioral and environmental practices that must be modified to prevent continued transmission of cysticercosis and taeniasis.
