Résumé
The diagnostic efficacy of an indirect enzyme linked immunosorbent assay (ELISA) was evaluated in cases of neurocystecercosis. Subjects studied included 22 cases and 30 controls (comprising 12 cases of surgically confirmed hydatid disease, 5 cases each of tuberculoma and P.U.O. and 8 cases of pyogenic meningitis). A standard ELISA was performed using porcine cysticerci as antigen. Sensitivity and specificity of the test were calculated for serum and cerebrospinal fluid separately. The test was found to give a sensitivity of 68 and 33 per cent for serum and C.S.F. respectively. The specificity for confirmed case was found to be cent per cent for both with the criteria of reporting used. The sensitivity of the test may be increased by using purified specific antigen and/or sandwich ELISA instead of indirect ELISA technique.
