          Abstract

          A dot-ELISA was developed for the detection of antibodies in CSF in the immunologic diagnosis of human neurocysticercosis, using antigen extracts of the membrane and scolex of Cysticercus cellulosae (M+S-Cc) and, alternately, membrane (M) and vesicular fluid (VF) of Cysticercus longicollis (Cl) covalently bound to a new solid phase consisting of polyester fabric treated with N-methylol-acrylamide resin (dot-RT). The test was performed at room temperature, with reduced incubation times and with no need for special care in the manipulation of the support. The sensitivity rates obtained were 95.1% for antigen Cc and 97.6% for antigen Cl. Specificity was 90.6% when Cc was used, and 96.9% and 100% when M-Cl and VF-Cl were used, respectively. No significant differences in titer were observed between tests carried out with homologous and heterologous antigens. The low cost and easy execution of the dot-RT test using antigen extracts of Cysticercus longicollis indicate the test for use in the immunodiagnosis of human neurocysticercosis.

          Foi desenvolvido o teste dot-ELISA para detecção de anticorpos em líquido cefalorraquiano (LCR) no diagnóstico imunológico da neurocisticercose humana, utilizando antígenos de membrana e escólex de Cysticercus cellulosae (M+E-Cc) e, alternativamente, membrana (M) e líquido vesicular (LV) de Cysticercus longicollis (Cl) covalentemente ligados a um novo suporte constituído de tecido de poliéster-resina de N-metilol-acrilamida (dot-TR). O teste foi realizado à temperatura ambiente, com tempos de incubação reduzidos e sem necessidade de cuidados na manipulação do suporte. A sensibilidade obtida foi de 95,1% para o antígeno Cc e 97,6% para o Cl. A especificidade foi de 90,6% quando o antígeno Cc foi usado, e 96,9% e 100% para M-Cl e LV-Cl, respectivamente. Não foi observada diferença significativa entre os antígenos homólogo e heterólogo. O baixo custo e a fácil execução do teste dot-TR empregando extratos antigênicos de Cysticercus longicollis indicam que pode ser empregado como alternativa no imunodiagnóstico da neurocisticercose humana.

            Clinical evaluation of the cysticercosis enzyme-linked immunoelectrotransfer blot in patients with neurocysticercosis.

            During the 3 years that the enzyme-linked immunoelectrotransfer blot (EITB) assay for the diagnosis of human cysticercosis has been in use at the Centers for Disease Control, 50 patients with both pathologically confirmed neurocysticercosis and computed tomographic (CT) or magnetic resonance imaging (MRI) scan results were identified. Of 32 patients with two or more lesions, 94% had detectable antibodies by EITB compared with 28% of 18 patients with single lesions. Patients with only calcified cysts (single or multiple) were less likely to have EITB-positive results than were those with noncalcified, enhancing lesions. Antibody was detectable more frequently in serum than in cerebrospinal fluid, regardless of the number or apparent condition of the cysts. These findings confirm 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.
