Seven patients with active neurocysticercosis (NCC) received an eight days treatment with albendazole and were followed up using computed tomography (CT-scan) and a monoclonal antibody based ELISA for the detection of circulating antigen (Ag-ELISA). Only three patients were cured as was shown by CT-scan and by the disappearance of circulating antigens one month after treatment. After a second course of albendazole therapy, two other patients became seronegative. CT-scan showed the disappearance of viable cysts in all persons who became seronegative whereas patients who were not cured remained seropositive. These preliminary results show that this Ag-ELISA is a promising technique for monitoring the success of treatment of NCC patients because of the excellent correlation between the presence of circulating antigens and of viable brain cysts.
Résumé
Sept patients atteints de neurocysticercose active (NCC) ont été traités à l'albendazole pendant huit jours et ont été suivis en utilisant la tomodensitométrie et un ELISA pour la détection d'antigènes circulants à base d'anticorps monoclonaux (Ag-ELISA). Seulement trois patients étaient guéris comme indiqué par le CT-scan et par la disparition des antigènes circulants un mois après traitement. Après un deuxième traitement à l’albendazole, deux outres patients sont devenus séronégatifs. Le CT-scan montrait la disparition de tous les cysticerques vivants chez les personnes qui étaient devenus séronégatifs, tandis que les patients qui n'étaient pas guéris restaient séropositifs. Ces résultats préliminaires montrent que l'Ag-ELISA est une technique prometteuse pour évaluer le succès d'un traitement de la neurocysticercose en raison de la corrélation excellente entre l'Ag-ELISA et la tomodensitométrie.
